Definitions

  • the invention relates to a screen for shielding from accidents, comprising frame-shaped support elements which each have at least two interconnected, vertical support posts and are covered or can be covered with a flexible sheet made of an opaque material and are held in support feet, and on a stand for such a screen.
  • a generic screen is the German Offenlegungsschrift DE 196 38 361 A1 refer to.
  • a vertical stand is inserted into several holding feet, and then a fabric web is stretched between these stands. Since each support foot can only carry one stand, there are large gaps between the individual stands, which are stabilized by horizontal expansion elements. The fabric web is then hung on slot-shaped recesses in the stands.
  • This system can be completely dismantled down to the individual components and thus stored and transported in a space-saving manner. However, a large number of handling steps are required for on-site assembly, which takes a long time.
  • the utility model DE 20 2014 009 447 U1 discloses a wind and / or privacy screen element for flat application to a building fence or the like, comprising a flat body with a plurality of fastening eyes or other fastening means for attachment to a building fence or the like, one or. in or on the two lateral areas of the flat body several lateral connecting elements are provided for connecting immediately adjacent flat bodies.
  • This privacy screen element is not suitable for shielding accidents on busy roads because the wide and bulky feet are an obstacle to traffic.
  • the disclosure WO 2010/031122 A1 discloses a fence panel support leg of the type which is arranged to support fence panels upright on a floor surface.
  • the support foot has a box-shaped foot block of sufficient weight and dimensions to prevent an upright fence panel from tipping over when it is mounted on the foot block and when the panel is subjected to predetermined forces normal to the expansion of the panel.
  • the mounting receptacles are arranged in one or more groups on the foot block, each group having at least three mounting receptacles which are arranged so close to one another that the upright mounting rods of the fence panels accommodated therein maintain a predetermined distance between them. Due to the voluminous box shape, this base is also not suitable for use on busy roads.
  • the wall component includes a pair of vertical posts. Each post has an upper component and a lower component with a hollow opening extending therethrough. However, there is no frame-shaped support element. This cannot be replaced by the vertical posts, so that use on busy roads is also out of the question here.
  • the disclosure WO 2016/139486 A1 shows a stand for a temporary lock, comprising a support portion made of plastic material, on which at least one upwardly extending pin or base or at least one recess is provided for inserting a part of the lock.
  • a frame-shaped support element and a flexible flat body instead of a frame-shaped support element and a flexible flat body, only one fencing panel is disclosed as a barrier. Since the base does not have a friction-increasing coating on its underside, it could slip into traffic and hinder it when used on a busy street.
  • each pedestal has an elongated plate, which is provided at least in some areas with a friction-increasing coating on its underside and is designed in such a way that it can be safely rolled over by a car tire and four upwardly projecting sleeves with a vertical longitudinal axis Inserting a vertical support post of a frame-shaped support element, wherein the four upstanding sleeves are arranged at the corners of a square, one diagonal of the square is arranged in the longitudinal direction of the elongated plate, the other diagonal transverse to it.
  • a plate-shaped foot has the advantage that it can be safely overrun by a car tire if necessary, which is particularly important if, for example, a driver is not concentrated enough at a carriageway area narrowed by an accident and comes too close to the screen according to the invention.
  • a vehicle tire will first roll over the pedestal facing the roadway, signaling to the driver with a noticeable blow that he is now getting too close to the front panel before anything actually happens. If the driver then reacts quickly enough, he can avert greater damage to his vehicle.
  • a pedestal Due to the friction-increasing coating on its underside, a pedestal resists any tendency to shift relative to the ground, which is particularly important when using it on motorways or along streets to shield an accident site in order to avoid that such a privacy fence shifted too far into the lane and could possibly hinder the flow of traffic there.
  • a plurality of upwardly projecting sleeves with a vertical longitudinal axis are provided on the elongate plate for inserting a vertical support post of a frame-shaped support element.
  • the use of several sleeves on a common plate has the advantage that several support posts can be anchored to a single stand. This in turn offers the possibility of being able to divide the support structure for a continuous screen wall into individual, prefabricated segments, which can then be transported in the fully assembled state and set up in a few simple steps.
  • Each segment of the screen wall or the support structure preferably extends from one base to an adjacent base.
  • a four-fold arrangement of the sleeves allows a certain amount of leeway in how a stand can be used.
  • the longitudinal axis of the base will be aligned approximately perpendicular to the course of the screen in order to ensure optimum stability;
  • a single stand could exceptionally be used parallel to the screen so that it does not protrude into the narrowed roadway.
  • the four upwardly projecting sleeves are arranged particularly close to one another, they are arranged at the corners of a square, preferably at the corners of a square. With such a positioning of the sleeves, minimal mutual distances can be realized. There could be another sleeve in the middle of the square; however, the invention recommends dispensing with such a central sleeve in order to be able to minimize the mutual distance between the four sleeves.
  • one diagonal of the square or square is arranged in the longitudinal direction of the elongated plate, the other diagonal transverse to it. Every support post can be inserted into any sleeve; However, if there are only two support posts meeting each other on a pedestal, it is preferred that the sleeves be occupied such that the two sleeves located near the long sides of the pedestal are used and the pedestal itself is aligned approximately such that its longitudinal axis roughly corresponds to the course of the bisector between the two supporting elements anchored there follows; If they extend in a common line of alignment, the longitudinal axis of the base points as perpendicular as possible to that line.
  • a covering attached to the underside of a pedestal and increasing the slip resistance should contain natural and / or synthetic rubber.
  • a rather soft material can adapt better to uneven floors and will therefore find a better grip on a road surface than a harder material.
  • the invention recommends that the nature and / or synthetic rubber of a friction-increasing covering on the underside of a pedestal is mixed with sulfur and vulcanized. As a result, the mechanical strength of the material is further improved, which in this case is not damaged even in the case of rather rough operation on a construction site or the like.
  • carbon black and / or zinc oxide and / or silicon dioxide and / or chalk and / or kaolin and / or antioxidants can be added to the natural and / or synthetic rubber of a friction-increasing covering on the underside of a pedestal, preferably in an amount of up to at 20% by weight or above. These substances give the friction-increasing covering particularly preferred properties.
  • a covering which is attached to the underside of a pedestal and increases the slip resistance is made of rubber, in particular hard rubber.
  • Hard rubber in particular can carry a greater weight without significant deformation
  • the elongate plate should be provided with a friction-increasing covering on its underside, at least in some areas, for example made of hard rubber. Since the subsoil will mostly be a road surface, in particular made of asphalt, materials of the type that are also used for car tires can be considered. The goal should be the highest possible slip resistance, in other words a high coefficient of static friction.
  • Another measure to increase the slip resistance is to provide at least one friction-increasing profile on the underside of the elongated plate, for example with groove-shaped depressions that are parallel and / or intersect with one another. It is advisable to select those areas for this which are designed as preferred contact areas and thus normally have direct contact with the ground or the road surface, for example, coverings made of a non-slip material arranged on the underside of the plate.
  • the invention provides that the elongate plate has on its underside two raised end regions arranged in the region of its front ends, and an intermediate region arranged therebetween, which is set back in comparison therewith. These end areas have the maximum mutual distance and therefore offer the highest possible stability against tipping, which is why they are best suited in terms of the best possible stability. Because these two end areas are lower than the middle area in between, Even with slightly uneven floors, it is ensured that precisely these end areas are in contact with the floor.
  • An embodiment of the invention has proven to be optimal for stability, the elongated plate having a flat underside with two shoulders attached to it in the region of its front ends, preferably projecting downward, from an elastic material such as hard rubber, the undersides of which are profiled.
  • the elongated plate may be more than twice as long as wide, preferably it is more than three times as long as wide, in particular more than four times as long as wide, or even five times as long as wide or more than five times as long.
  • the invention recommends that the length of one, several or all of the upstanding sleeves is at least twice as large as the thickness of the elongated plate of the relevant stand, for example at least four times as large as the thickness of the elongated plate, preferably at least six times as large as the thickness of the elongated plate, in particular at least eight times as large as the thickness of the elongated plate.
  • This provides an inserted support post with good lateral support.
  • the thickness of the plate can preferably be 8 mm or more, preferably 10 mm or more, in particular 12 mm or more. A higher thickness of the plate not only gives it a higher rigidity, but also a higher weight, which has a positive effect on the stability of the support structure.
  • each support post can optionally be inserted into any sleeve, depending on the local conditions. In particular, it can also be used to realize T-shaped or even X-shaped profiles of the screen, where three or even four support elements meet on a pedestal.
  • the four upwardly projecting sleeves are arranged close to one another, preferably at or near the center of the elongated plate.
  • a flap made of opaque material When placed at or near the center of the elongated plate, the center of gravity of the inserted support post is above the center of the pedestal, and this can provide the relevant support elements with maximum stability against tilting.
  • the elongate plate can be provided below the sleeves with a recess, which preferably corresponds in its cross-sectional area to the clear inner cross section of a sleeve.
  • a recess which preferably corresponds in its cross-sectional area to the clear inner cross section of a sleeve.
  • the elongate plate and / or the sleeves consist of metal, preferably of iron or steel.
  • metal preferably of iron or steel.
  • such a material offers maximum stability and, on the other hand, it provides a not inconsiderable weight, which improves the stability.
  • the invention recommends that the sleeves are connected to the elongated plate, preferably welded, soldered or glued. As a result, in particular tilting moments and / or lateral forces introduced into the sleeves by the support posts can be reliably derived into the base.
  • the elongate plate should have one, two or more handles.
  • the invention recommends that the handle (s) be designed as a U-shaped bracket with two short legs that are connected by a longer central web, so that the central web can be gripped by one hand while the Give both shorter legs security against slipping. Especially in view of the traffic flowing past an accident site, a high level of grip security is important.
  • At least one handle should be attached to or in the top of the elongated plate, preferably welded, soldered or glued.
  • An optimal wearing position is favored by the fact that at least one handle extends transversely to the longitudinal axis of the elongated plate.
  • a stand can be held or carried with its longitudinal axis transversely in front of the stomach.
  • a handle is located in an area between the sleeves and a front end, in particular between the sleeves on the one hand and an end shoulder, a stand can also be held with only one hand, the end area opposite the handle used then hanging approximately vertically.
  • a strong person is able to grab and carry two feet at the same time, which is also preferable from an ergonomic point of view, because this places a symmetrical load on the spine and the weight does not hang in front of the spine, but rather on a level surface The spine.
  • a weight of, for example, four to ten kilograms per stand, this aspect is not unimportant.
  • a base of a screen according to the invention preferably has one or more bores in the elongated plate, so that such a base can also be anchored to the floor, if necessary, for example by screwing on, by means of dowels or with earth spikes. Furthermore, a base could also be fixed for storage purposes, for example on a fixing rod.
  • the anchoring means to be used there i.e. screws, dowels, earth spikes or the like easily accessible.
  • the support elements each have at least two vertical support posts connected to one another.
  • a sheet of opaque material can be optimally anchored between two such support posts.
  • a another support element with one of its support posts can be placed immediately afterwards in order to create a complete privacy screen.
  • frame-shaped support elements offer the possibility of providing them with a lattice within the frame, as a result of which a sheet of an opaque material between the support posts or other parts of the frame is not left to itself, but rather - in the case of a gust of wind - adheres to one Can nestle mesh.
  • a sheet made of an opaque material can be clamped or anchored to a support element in that it is attached to the vertical support posts and / or to the horizontal connecting bars of a frame-shaped support element, for example by means of rings, cords, wires arranged through holes or eyes in the sheet or the like. There is also the possibility of threading a tension wire through a series of eyelets of the opaque web, which is then anchored to the support element.
  • the opaque web can consist of a flexible material, for example a tarpaulin material for trucks and / or a fabric, for example of linen or canvas.
  • This can be a light material, which can save weight, so that a individual support element can be transported and erected by a maximum of two people or possibly even by a single person.
  • such a track can be provided with information, for example with warning signals and / or warning colors, or with an instruction to continue carefully, etc.
  • a web has at least one overlap region in at least one area of a joint between adjacent support elements. This can, for example, follow the course of a vertical support post with a width of a few centimeters, for example five to twelve centimeters, and thus extends to an adjacent support post.
  • an overlap area can be defined on a subsequent web by means of a Velcro connection.
  • the invention is characterized by a base for a screen for shielding from accidents, with frame-shaped support elements which each have at least two interconnected vertical support posts and are covered or can be covered with a flexible sheet made of an opaque material and are held in support feet, wherein the base has an elongated plate and four sleeves projecting upward from this elongated plate with a vertical longitudinal axis for inserting a vertical support post of a frame-shaped support element.

  • Such a support element 3 comprising support posts 4, connecting bars 5 and, if appropriate, a filling, for example in the form of a mat or a mesh, is then covered or can be covered with a web 6 made of an opaque material.
  • This can be a tarpaulin, in the manner of a tarpaulin for a truck, or a fabric, for example made of linen or canvas; but it is also conceivable to use a thin plastic plate for this.

Description

Die Erfindung richtet sich auf eine Sichtblende zum Abschirmen von Unfällen, umfassend rahmenförmige Stützelemente, die zumindest jeweils zwei miteinander verbundene, vertikale Stützpfosten aufweisen und mit einer flexiblen Bahn aus einem undurchsichtigen Material bespannt oder bespannbar sind und in Stützfüßen gehalten werden, sowie auf einen Standfuß für eine solche Sichtblende.The invention relates to a screen for shielding from accidents, comprising frame-shaped support elements which each have at least two interconnected, vertical support posts and are covered or can be covered with a flexible sheet made of an opaque material and are held in support feet, and on a stand for such a screen.

Eine gattungsgemäße Sichtblende ist der deutschen Offenlegungsschrift DE 196 38 361 A1 zu entnehmen. Gemäß der dortigen Vorerfindung werden in mehreren Haltefüßen je ein vertikale Ständer eingesteckt, und sodann wird zwischen diesen Ständern eine Gewebebahn gespannt. Da hierbei jeder Haltefuß nur einen Ständer tragen kann, befinden sich zwischen den einzelnen Ständern jeweils große Abstände, welche durch horizontale Spreizelemente stabilisiert werden. Die Gewebebahn wird dann an schlitzförmigen Ausnehmungen in den Ständern eingehängt. Zwar lässt sich dieses System bis herab zu den Einzelkomponenten vollständig zerlegen und somit platzsparend aufbewahren und transportieren. Jedoch sind für den Aufbau vor Ort eine Vielzahl von Handhabungsschritten erforderlich, was viel Zeit in Anspruch nimmt.A generic screen is the German Offenlegungsschrift DE 196 38 361 A1 refer to. According to the invention there, a vertical stand is inserted into several holding feet, and then a fabric web is stretched between these stands. Since each support foot can only carry one stand, there are large gaps between the individual stands, which are stabilized by horizontal expansion elements. The fabric web is then hung on slot-shaped recesses in the stands. This system can be completely dismantled down to the individual components and thus stored and transported in a space-saving manner. However, a large number of handling steps are required for on-site assembly, which takes a long time.

Die Gebrauchsmusterschrift DE 20 2014 009 447 U1 offenbart ein Wind- und/oder Sichtschutzelement zur flächigen Applikation an einem Bauzaun oder ggl., umfassend einen Flachkörper mit mehreren Befestigungsösen oder sonstigen Befestigungsmitteln zur Festlegung an einem Bauzaun od. dgl., wobei in oder an den beiden seitlichen Bereichen des Flachkörpers jeweils ein oder mehrere seitliche Verbindungselemente zum Verbinden unmittelbar benachbarter Flachkörper vorgesehen sind. Dieses Sichtschutzelement ist nicht für das Abschirmen von Unfällen an befahrenen Straßen geeignet, weil die weit ankragenden und voluminösen Standfüße ein Hindernis für den Verkehr darstellen.The utility model DE 20 2014 009 447 U1 discloses a wind and / or privacy screen element for flat application to a building fence or the like, comprising a flat body with a plurality of fastening eyes or other fastening means for attachment to a building fence or the like, one or. in or on the two lateral areas of the flat body several lateral connecting elements are provided for connecting immediately adjacent flat bodies. This privacy screen element is not suitable for shielding accidents on busy roads because the wide and bulky feet are an obstacle to traffic.

Die Offenlegungsschrift WO 2010/031122 A1 offenbart einen Zaunpaneel-Stützfuß des Typs, der zum aufrechten Stützen von Zaunpaneelen auf einer Bodenfläche angeordnet ist. Der Stützfuß weist einen kastenförmigen Fußblock mit ausreichendem Gewicht und Abmessungen auf, um ein Umkippen einer aufrechten Zaunplatte zu verhindern, wenn sie an dem Fußblock montiert ist und wenn die Platte vorbestimmten Kräften ausgesetzt ist, die normal zur Ausdehnung der Platte sind. Es gibt drei oder mehr Befestigungsaufnahmen zur Aufnahme je eines aufrechten Befestigungspfostens eines Zaunpaneels. Die Montageaufnahmen sind in einer oder mehreren Gruppen am Fußblock angeordnet, wobei jede Gruppe mindestens drei Montageaufnahmen aufweist, die so nahe beieinander angeordnet sind, dass die aufrechten Montagestangen der darin aufgenommenen Zaunplatten einen vorbestimmten Abstand zwischen sich einhalten. Aufgrund der voluminösen Kastenform ist auch dieser Standfuß für den Einsatz auf befahrenen Straßen nicht geeignet.The disclosure WO 2010/031122 A1 discloses a fence panel support leg of the type which is arranged to support fence panels upright on a floor surface. The support foot has a box-shaped foot block of sufficient weight and dimensions to prevent an upright fence panel from tipping over when it is mounted on the foot block and when the panel is subjected to predetermined forces normal to the expansion of the panel. There are three or more mounting brackets to hold an upright mounting post on a fence panel. The mounting receptacles are arranged in one or more groups on the foot block, each group having at least three mounting receptacles which are arranged so close to one another that the upright mounting rods of the fence panels accommodated therein maintain a predetermined distance between them. Due to the voluminous box shape, this base is also not suitable for use on busy roads.

In der Patentschrift US 5,553,648 ist eine tragbare Wandkomponente offenbart. Die Wandkomponente umfasst ein Paar vertikaler Pfosten. Jeder Pfosten hat eine obere Komponente und eine untere Komponente mit einer sich dadurch erstreckenden hohlen Öffnung. Hierbei fehlt es jedoch an einem rahmenförmigen Stützelement. Dieses kann durch die vertikalen Pfosten nicht ersetzt werden, sodass auch hier ein Einsatz auf befahrenen Straßen nicht in Betracht kommt.In the patent US 5,553,648 a portable wall component is disclosed. The wall component includes a pair of vertical posts. Each post has an upper component and a lower component with a hollow opening extending therethrough. However, there is no frame-shaped support element. This cannot be replaced by the vertical posts, so that use on busy roads is also out of the question here.

Die Offenlegungsschrift WO 2016/139486 A1 zeigt einen Standfuß für eine vorübergehende Sperre, umfassend einen Stützabschnitt aus Kunststoffmaterial, auf dem wenigstens ein sich nach oben erstreckender Zapfen oder Sockel oder wenigstens eine Vertiefung zum Einstecken eines Teils der Sperre vorgesehen ist. Als Sperre ist anstelle eines rahmenförmigen Stützelements und eines flexiben Flachkörpers nur ein Umzäunungspaneel offenbart. Da der Standfuß keinen reibungserhöhenden Belag an seiner Unterseite aufweist, könnte dieser beim Einsatz an einer befahrenen Straße in den Verkehr rutschen und diesen behindern.The disclosure WO 2016/139486 A1 shows a stand for a temporary lock, comprising a support portion made of plastic material, on which at least one upwardly extending pin or base or at least one recess is provided for inserting a part of the lock. Instead of a frame-shaped support element and a flexible flat body, only one fencing panel is disclosed as a barrier. Since the base does not have a friction-increasing coating on its underside, it could slip into traffic and hinder it when used on a busy street.

Aus den Nachteilen des beschriebenen Standes der Technik resultiert das die Erfindung initiierende Problem, eine gattungsgemäße Sichtblende zum Abschirmen von Unfällen derart weiterzubilden, dass die Sichtblende möglichst schnell auf- und wieder abgebaut werden kann und eine möglichst gute Standfestigkeit aufweist.The disadvantages of the prior art described result in the problem initiating the invention of developing a generic screen for shielding against accidents in such a way that the screen can be assembled and disassembled as quickly as possible and has the best possible stability.

Die Lösung dieses Problems gelingt dadurch, dass jeder Standfuß eine langgestreckte Platte aufweist, die an ihrer Unterseite zumindest bereichsweise mit einem reibungserhöhenden Belag versehen ist und derart ausgebildet ist, dass sie von einem Autoreifen gefahrlos überrollbar ist sowie vier nach oben ragende Hülsen mit vertikaler Längsachse zum Einstecken je eines vertikalen Stützpfostens eines rahmenförmigen Stützelements aufweist, wobei die vier nach oben ragenden Hülsen an den Ecken eines Vierecks angeordnet sind, wobei eine Diagonale des Vierecks in Längsrichtung der langgestreckten Platte angeordnet ist, die andere Diagonale quer dazu.The solution to this problem is achieved in that each pedestal has an elongated plate, which is provided at least in some areas with a friction-increasing coating on its underside and is designed in such a way that it can be safely rolled over by a car tire and four upwardly projecting sleeves with a vertical longitudinal axis Inserting a vertical support post of a frame-shaped support element, wherein the four upstanding sleeves are arranged at the corners of a square, one diagonal of the square is arranged in the longitudinal direction of the elongated plate, the other diagonal transverse to it.

Ein plattenförmiger Fuß hat den Vorteil, dass dieser notfalls von einem Autoreifen gefahrlos überrollt werden kann, was besonders dann wichtig ist, wenn bspw. an einer durch einen Unfall verengten Fahrbahnstelle ein Fahrer nicht konzentriert genug ist und der erfindungsgemäßen Sichtblende zu nahe kommt. Bevor das Fahrzeug an der Sichtblende anstreift, wird zunächst ein Fahrzeugreifen den der Fahrebahn zugewandten Standfuß überrollen und damit dem Fahrer mit einem spürbaren Schlag signalisieren, dass er nun der Sichtblende zu nah kommt, bevor tatsächlich etwas passiert. Sofern der Autofahrer dann schnell genug reagiert, kann er größeren Schaden an seinem Fahrzeug abwenden.A plate-shaped foot has the advantage that it can be safely overrun by a car tire if necessary, which is particularly important if, for example, a driver is not concentrated enough at a carriageway area narrowed by an accident and comes too close to the screen according to the invention. Before the vehicle touches the front panel, a vehicle tire will first roll over the pedestal facing the roadway, signaling to the driver with a noticeable blow that he is now getting too close to the front panel before anything actually happens. If the driver then reacts quickly enough, he can avert greater damage to his vehicle.

Durch den reibungserhöhenden Belag an seiner Unterseite widersetzt sich ein Standfuß jeder Tendenz einer Verschiebung gegenüber dem Untergrund, was insbesondere bei der Verwendung an Autobahnen oder entlang von Straßen zur Abschirmung einer Unfallstelle wichtig ist, um zu vermeiden, dass sich ein solcher Sichtschutzzaun zu weit in die Fahrbahn hinein verlagert und dadurch eventuell den dortigen Verkehrsfluß behindern könnte.Due to the friction-increasing coating on its underside, a pedestal resists any tendency to shift relative to the ground, which is particularly important when using it on motorways or along streets to shield an accident site in order to avoid that such a privacy fence shifted too far into the lane and could possibly hinder the flow of traffic there.

An der langgestreckten Platte sind mehrere nach oben ragende Hülsen mit vertikaler Längsachse zum Einstecken je eines vertikalen Stützpfostens eines rahmenförmigen Stützelements vorgesehen. Die Verwendung mehrerer Hülsen an einer gemeinsamen Platte hat den Vorteil, dass mehrere Stützpfosten an einem einzigen Standfuß verankert werden können. Dies wiederum bietet die Möglichkeit, die-Stützkonstruktion für eine durchgehende Sichtschutzwand in einzelne, vorgefertigte Segmente aufteilen zu können, die dann in fertig montiertem Zustand antransportiert und mit wenigen Handgriffen aufgestellt werden können. Vorzugsweise erstreckt sich dabei jedes Segment der Sichtschutzwand bzw. der Stützkonstruktion von einem Standfuß bis zu einem benachbarten Standfuß.A plurality of upwardly projecting sleeves with a vertical longitudinal axis are provided on the elongate plate for inserting a vertical support post of a frame-shaped support element. The use of several sleeves on a common plate has the advantage that several support posts can be anchored to a single stand. This in turn offers the possibility of being able to divide the support structure for a continuous screen wall into individual, prefabricated segments, which can then be transported in the fully assembled state and set up in a few simple steps. Each segment of the screen wall or the support structure preferably extends from one base to an adjacent base.

Eine Vierfach-Anordnung der Hülsen gewährt einen gewissen Spielraum, wie ein Standfuß eingesetzt werden kann. Zwar wird im Normalfall die Längsachse des Standfußes etwa lotrecht zu dem Verlauf der Sichtblende ausgerichtet sein, um eine optimale Standfestigkeit zu gewähren; an besonderen Engstellen könnte aber ausnahmsweise auch ein einzelner Standfuß einmal parallel zu der Sichtblende eingesetzt werden, so dass er nicht in die verengte Fahrbahn hineinragt.A four-fold arrangement of the sleeves allows a certain amount of leeway in how a stand can be used. In the normal case, the longitudinal axis of the base will be aligned approximately perpendicular to the course of the screen in order to ensure optimum stability; In exceptional constrictions, however, a single stand could exceptionally be used parallel to the screen so that it does not protrude into the narrowed roadway.

Damit die vier nach oben ragenden Hülsen besonders nahe beieinander angeordnet sind, sind diese an den Ecken eines Vierecks angeordnet, vorzugsweise an den Ecken eines Quadrats. Bei einer derartigen Positionierung der Hülsen lassen sich minimale gegenseitige Abstände realisieren, Zwar könnte sich in der Mitte des Quadrats eine weitere Hülse befinden; die Erfindung empfiehlt jedoch, auf eine solche, zentrale Hülse zu verzichten, um den gegenseitigen Abstand zwischen den vier Hülsen minimieren zu können.So that the four upwardly projecting sleeves are arranged particularly close to one another, they are arranged at the corners of a square, preferably at the corners of a square. With such a positioning of the sleeves, minimal mutual distances can be realized. There could be another sleeve in the middle of the square; however, the invention recommends dispensing with such a central sleeve in order to be able to minimize the mutual distance between the four sleeves.

Eine weitere Besonderheit der Erfindung ist, dass eine Diagonale des Vierecks oder Quadrats in Längsrichtung der langgestreckten Platte angeordnet ist, die andere Diagonale quer dazu. Zwar kann jeder Stützpfosten in jede beliebige Hülse eingesteckt werden; bevorzugt wird aber bei nur zwei einander an einem Standfuß begegnenden Stützpfosten eine Belegung der Hülsen derart, dass die beiden nahe den Längsseiten des Standfußes befindlichen Hülsen verwendet werden und der Standfuß selber etwa derart ausgerichtet wird, dass seine Längsachse etwa dem Verlauf der Winkelhalbierenden zwischen den beiden dort verankerten Stützelementen folgt; erstrecken sich jene in einer gemeinsamen Fluchtlinie, so zeigt die Längsachse des Standfußes möglichst lotrecht zu jener Linie.Another special feature of the invention is that one diagonal of the square or square is arranged in the longitudinal direction of the elongated plate, the other diagonal transverse to it. Every support post can be inserted into any sleeve; However, if there are only two support posts meeting each other on a pedestal, it is preferred that the sleeves be occupied such that the two sleeves located near the long sides of the pedestal are used and the pedestal itself is aligned approximately such that its longitudinal axis roughly corresponds to the course of the bisector between the two supporting elements anchored there follows; If they extend in a common line of alignment, the longitudinal axis of the base points as perpendicular as possible to that line.

Ein an der Unterseite eines Standfußes befestigter, die Rutschsicherheit erhöhender Belag sollte Natur- und/oder Synthesekautschuk enthalten. Ein eher weiches Material kann sich Bodenunebenheiten besser anpassen und wird daher auf einer Fahrbahnoberfläche eher Halt finden als ein härteres Material.A covering attached to the underside of a pedestal and increasing the slip resistance should contain natural and / or synthetic rubber. A rather soft material can adapt better to uneven floors and will therefore find a better grip on a road surface than a harder material.

Die Erfindung empfiehlt, dass der Natur und/oder Synthesekautschuk eines reibungserhöhenden Belags an der Unterseite eines Standfußes mit Schwefel versetzt und vulkanisiert ist. Dadurch wird die mechanische Beanspruchungsfähigkeit des Materials weiter verbessert, welches solchenfalls auch bei einem eher rauhen Betrieb auf einer Baustelle od. dgl. keinen Schaden nimmt.The invention recommends that the nature and / or synthetic rubber of a friction-increasing covering on the underside of a pedestal is mixed with sulfur and vulcanized. As a result, the mechanical strength of the material is further improved, which in this case is not damaged even in the case of rather rough operation on a construction site or the like.

Weiterhin kann/können dem Natur- und/oder Synthesekautschuk eines reibungserhöhenden Belags an der Unterseite eines Standfußes Ruß und/oder Zinkoxid und/oder Siliziumdioxid und/öder Kreide und/oder Kaolin und/oder Antioxidantien beigemengt sein, bevorzugt in einer Menge von insgesamt bis zu 20 Gew.-% oder darüber. Diese Substanzen verleihen dem reibungserhöhenden Belag besonders bevorzugte Eigenschaften.Furthermore, carbon black and / or zinc oxide and / or silicon dioxide and / or chalk and / or kaolin and / or antioxidants can be added to the natural and / or synthetic rubber of a friction-increasing covering on the underside of a pedestal, preferably in an amount of up to at 20% by weight or above. These substances give the friction-increasing covering particularly preferred properties.

Es liegt im Rahmen der Erfindung, dass ein an der Unterseite eines Standfußes befestigter, die Rutschsicherheit erhöhender Belag aus Gummi besteht, insbesondere aus Hartgummi. Besonders Hartgummi kann ein größeres Gewicht tragen, ohne eine nennenswerte Verformung,It is within the scope of the invention that a covering which is attached to the underside of a pedestal and increases the slip resistance is made of rubber, in particular hard rubber. Hard rubber in particular can carry a greater weight without significant deformation,

Damit insbesondere Seitenkräfte möglichst optimal in einen Untergrund eingeleitet werden können, sollte die langgestreckte Platte an ihrer Unterseite zumindest bereichsweise mit einem reibungserhöhenden Belag versehen sein, beispielsweise aus Hartgummi. Da der Untergrund zumeist ein Fahrbahnbelag sein wird, insbesondere aus Asphalt, kommen hierfür beispielsweise derartige Materialien in Betracht, wie sie auch für Autoreifen verwendet werden. Das Ziel sollte dabei eine möglichst hohe Rutschfestigkeit sein, mit anderen Worten ein hoher Haftreibungskoeffizient.So that in particular lateral forces can be optimally introduced into a subsurface, the elongate plate should be provided with a friction-increasing covering on its underside, at least in some areas, for example made of hard rubber. Since the subsoil will mostly be a road surface, in particular made of asphalt, materials of the type that are also used for car tires can be considered. The goal should be the highest possible slip resistance, in other words a high coefficient of static friction.

Eine weitere Maßnahme zur Steigerung der Rutschfestigkeit besteht darin, an der Unterseite der langgesteckten Platte zumindest ein reibungserhöhendes Profil vorzusehen, beispielsweise mit zueinander parallelen und/oder einander kreuzenden, rillenförmigen Vertiefungen. Es bietet sich an, hierfür diejenigen Bereiche auszuwählen, welche als bevorzugte Aufstandsflächen ausgebildet sind und also im Normalfall direkten Kontat zum Untergrund bzw. zue Fahrbahnoberfläche haben, bspw. an der Unterseite der Platte angeordnete Beläge aus einem rutschhemmenden Material.Another measure to increase the slip resistance is to provide at least one friction-increasing profile on the underside of the elongated plate, for example with groove-shaped depressions that are parallel and / or intersect with one another. It is advisable to select those areas for this which are designed as preferred contact areas and thus normally have direct contact with the ground or the road surface, for example, coverings made of a non-slip material arranged on the underside of the plate.

In Weiterbildung dieses Erfindungsgedankens sieht die Erfindung vor, dass die langgestreckte Platte an ihrer Unterseite zwei im Bereich ihrer stirnseitigen Enden angeordnete, erhabene Endbereiche aufweist, sowie einen dazwischen angeordneten, demgegenüber nach oben zurückversetzten Mittelbereich. Diese endseitigen Bereiche weisen den maximalen gegenseitigen Abstand auf und bieten also die höchstmögliche Kippsicherheit, weshalb diese im Hinblick auf eine bestmögliche Standsicherheit am besten geeignet sind. Indem diese beiden Endbereiche tiefer liegen als der dazwischen befindliche Mittelbereich, wird auch bei leicht unebenem Boden sichergestellt, dass genau diese Endbereiche Bodenkontakt haben.In a further development of this inventive concept, the invention provides that the elongate plate has on its underside two raised end regions arranged in the region of its front ends, and an intermediate region arranged therebetween, which is set back in comparison therewith. These end areas have the maximum mutual distance and therefore offer the highest possible stability against tipping, which is why they are best suited in terms of the best possible stability. Because these two end areas are lower than the middle area in between, Even with slightly uneven floors, it is ensured that precisely these end areas are in contact with the floor.

Für die Standfestigkeit optimal erwiesen hat sich eine Ausbildung der Erfindung, wobei die langgestreckte Platte eine ebene Unterseite aufweist mit zwei im Bereich ihrer stirnseitigen Enden daran befestigten, vorzugsweise nach unten ragenden Absätzen aus einem elastischen Material wie Hartgummi, deren Unterseiten profiliert sind.An embodiment of the invention has proven to be optimal for stability, the elongated plate having a flat underside with two shoulders attached to it in the region of its front ends, preferably projecting downward, from an elastic material such as hard rubber, the undersides of which are profiled.

Es hat sich als günstig erwiesen, dass die langgesteckte Platte eine rechteckige Grundfläche aufweist. Dies bietet den Vorteil, dass quer dazu verlaufende Stützelemente selbst gegenüber Windböen einen ausreichenden Seitenhalt erfahren. Die Platte kann beispielsweise mehr als doppelt so lang als breit sein, bevorzugt ist sie mehr als dreimal so lang als breit, insbesondere mehr als viermal so lang als breit, oder sogar fünfmal so lang als breit oder mehr als fünf mal so lang.It has proven to be advantageous for the elongated plate to have a rectangular base area. This offers the advantage that transverse support elements experience sufficient lateral support even against wind gusts. For example, the plate may be more than twice as long as wide, preferably it is more than three times as long as wide, in particular more than four times as long as wide, or even five times as long as wide or more than five times as long.

Andererseits empfiehlt die Erfindung, dass die Länge einer, mehrerer oder aller nach oben ragenden Hülsen jeweils wenigstens doppelt so groß ist wie die Dicke der langgesteckten Platte des betreffenden Standfußes, beispielsweise wenigstens vier mal so groß ist wie die Dicke der langgestreckten Platte, vorzugsweise wenigstens sechs mal so groß wie die Dicke der langgestreckten Platte, inbesondere wenigstens acht mal so groß wie die Dicke der langgestreckten Platte, Dadurch erfährt ein eingesteckter Stützpfosten einen guten Seitenhalt.On the other hand, the invention recommends that the length of one, several or all of the upstanding sleeves is at least twice as large as the thickness of the elongated plate of the relevant stand, for example at least four times as large as the thickness of the elongated plate, preferably at least six times as large as the thickness of the elongated plate, in particular at least eight times as large as the thickness of the elongated plate. This provides an inserted support post with good lateral support.

Die Dicke der Platte kann bevorzugt 8 mm oder mehr betragen, vorzugsweise 10 mm oder mehr, insbesondere 12 mm oder mehr. Durch eine höhere Stärke der Platte erhält diese nicht nur eine höhere Steifigkeit, sondern auch ein höheres Gewicht, was sich positiv auf die Standfestigkeit der Stützkonstruktion auswirkt.The thickness of the plate can preferably be 8 mm or more, preferably 10 mm or more, in particular 12 mm or more. A higher thickness of the plate not only gives it a higher rigidity, but also a higher weight, which has a positive effect on the stability of the support structure.

Die vier nach oben ragenden Hülsen sollten gleiche Längen aufweisen, und/oder gleiche Innendurchmesser. Dadurch kann jeder Stützpfosten wahlweise in Jede beliebige Hülse eingesteckt werden, je nach den örtlichen Verhältnissen. Insbesondere lassen sich damit auch T- oder gar X-förmige Verläufe der Sichtblende realisieren, wo sich dann drei oder gar vier Stützelemente an einem Standfuß begegnen.The four upstanding sleeves should have the same length and / or the same inside diameter. As a result, each support post can optionally be inserted into any sleeve, depending on the local conditions. In particular, it can also be used to realize T-shaped or even X-shaped profiles of the screen, where three or even four support elements meet on a pedestal.

Es liegt im Rahmen der Erfindung, dass die vier nach oben ragenden Hülsen nahe beeinander angeordnet sind, vorzugsweise an oder nahe der Mitte der langgestreckten Platte. Solchenfalls verbleibt zwischen zwei in verschiedenen Hülsen desselben Standfußes eingesteckten Stützelementen nur ein vergleichsweise schmaler Spalt, der einerseits kaum Durchblick erlaubt, und der andererseits leicht durch eine Lasche aus undurchsichtigem Material überdeckt werden kann. Bei einer Platzierung an oder nahe der Mitte der langgestreckten Platte befindet sich der Schwerpunkt des (der) eingesteckten Stützpfosten oberhalb der Mitte des Standfußes, und dieser kann den betreffenden Stützelementen eine maximale Stabilität gegenüber Verkippen gewähren.It is within the scope of the invention that the four upwardly projecting sleeves are arranged close to one another, preferably at or near the center of the elongated plate. In such a case, only a comparatively narrow gap remains between two support elements inserted in different sleeves of the same base, which on the one hand hardly allows a view and which on the other hand can easily be covered by a flap made of opaque material. When placed at or near the center of the elongated plate, the center of gravity of the inserted support post is above the center of the pedestal, and this can provide the relevant support elements with maximum stability against tilting.

Die langgestreckte Plattekann unterhalb der Hülsen mit je einer Ausnehmung versehen sein, welche vorzugsweise in ihrer Querschnittsfläche dem lichten Innenquerschnitt einer Hülse entspricht. Dadurch bleibt bspw. bei Regen entlang der Stützpfosten herab rinnende Feuchtigkeit nicht in den Hülsen stehen, sondern verlässt jene an der jeweiligen, unteren Ausnehmung in der Platte. Dadurch wird einer potentiellen Verschmutzung, aber auch Rost vorgebeugt.The elongate plate can be provided below the sleeves with a recess, which preferably corresponds in its cross-sectional area to the clear inner cross section of a sleeve. As a result, for example, in the case of rain, moisture running down the support posts does not remain in the sleeves, but leaves them at the respective lower recess in the plate. This prevents potential pollution, but also rust.

Weitere Vorteile ergeben sich dadurch, dass die langgestreckte Platte und/oder die Hülsen aus Metall bestehen, vorzugsweise aus Eisen oder Stahl. Ein solches Material bietet einerseits ein Höchstmaß an Stabilität und liefert andererseits auch ein nicht unbetrachtliches Gewicht, was die Standfestigkeit verbessert.Further advantages result from the fact that the elongate plate and / or the sleeves consist of metal, preferably of iron or steel. On the one hand, such a material offers maximum stability and, on the other hand, it provides a not inconsiderable weight, which improves the stability.

Eine Maßnahme zum Schutz der langgestreckten Platte und/oder der Hülsen vor Korrosion besteht darin, jene zu verzinken. Natürlich kann stattdessen auch eine Rostschutzfarbe aufgetragen werden, was im Allgemeinen jedoch nur eine verminderte Korrosionsbeständigkeit liefert.One measure to protect the elongated plate and / or the sleeves from corrosion is to galvanize them. Of course, an anti-rust paint can also be applied instead, but this generally only provides reduced corrosion resistance.

Die Erfindung empfiehlt, dass die Hülsen mit der langgestreckten Platte verbunden sind, vorzugsweise verschweißt, verlötet oder verklebt. Dadurch können insbesondere von den Stützpfosten in die Hülsen eingeleitete Kippmomente und/oder Seitenkräfte sicher in den Standfuß abgeleitet werden.The invention recommends that the sleeves are connected to the elongated plate, preferably welded, soldered or glued. As a result, in particular tilting moments and / or lateral forces introduced into the sleeves by the support posts can be reliably derived into the base.

Um den Auf- und Abbau der erfindungsgemäßen Sichtblende so weit als möglich zu vereinfachen, sollte die langgestreckte Platte einen, zwei oder mehrere Tragegriffe aufweisen.In order to simplify the assembly and disassembly of the screen according to the invention as much as possible, the elongate plate should have one, two or more handles.

Aufgrund des erhöhten Gewichts eines Standfußes empfiehlt die Erfindung, den (die) Tragegriff(e) als U-förmiger Bügel auszubilden mit zwei kurzen Schenkeln, die durch einen längeren Mittelsteg verbunden sind, so dass der Mittelsteg von einer Hand umgriffen werden kann, während die beiden kürzeren Schenkel Sicherheit vor einem Abrutschen geben. Gerade in Anbetracht des an einer Unfallstelle unmittelbar vorbeifließenden Verkehrs ist eine hohe Griffsicherheit wichtig.Due to the increased weight of a pedestal, the invention recommends that the handle (s) be designed as a U-shaped bracket with two short legs that are connected by a longer central web, so that the central web can be gripped by one hand while the Give both shorter legs security against slipping. Especially in view of the traffic flowing past an accident site, a high level of grip security is important.

Damit nach dem Herausziehen der Stützpfosten eine Person die Standfüße einfach und sicher ergreifen und einsammeln kann, sollte wenigstens ein Tragegriff an oder in der Oberseite der langgestreckten Platte befestigt sein, vorzugsweise angeschweißt, angelötet oder angeklebt.So that a person can easily and safely grab and collect the feet after pulling out the support posts, at least one handle should be attached to or in the top of the elongated plate, preferably welded, soldered or glued.

Eine optimale Trageposition wird dadurch begünstigt, dass sich wenigstens ein Tragegriff quer zu der Längsachse der langgestreckten Platte erstreckt. Beispielsweise kann ein Standfuß solchermaßen mit seiner Längsachse quer vor dem Bauch gehalten oder getragen werden.An optimal wearing position is favored by the fact that at least one handle extends transversely to the longitudinal axis of the elongated plate. For example, a stand can be held or carried with its longitudinal axis transversely in front of the stomach.

Sofern ein Tragegriff sich in einem Bereich zwischen den Hülsen und einem stirnseitigen Ende befindet, insbesondere zwischen den Hülsen einerseits und einem endseitigen Absatz, kann ein Standfuß auch mit nur einer Hand gehalten werden, wobei dann der dem benutzten Tragegriff gegenüber liegende Endbereich etwa vertikal herabhängt. Somit ist eine kräftige Person in die Lage versetzt, gleichzeitig zwei Standfüße ergreifen und tragen zu können, was auch in ergonomischer Hinsicht zu bevorzugen ist, weil dadurch die Wirbelsäule symmetrisch belastet wird und dabei das Gewicht nicht vor der Wirbelsäule hängt, sondern etwa in der Ebene der Wirbelsäule. Gerade bei einem Gewicht von beispielsweise vier bis zehn Kilogramm pro Standfuß ist dieser Gesichtspunkt nicht unwichtig.If a handle is located in an area between the sleeves and a front end, in particular between the sleeves on the one hand and an end shoulder, a stand can also be held with only one hand, the end area opposite the handle used then hanging approximately vertically. Thus, a strong person is able to grab and carry two feet at the same time, which is also preferable from an ergonomic point of view, because this places a symmetrical load on the spine and the weight does not hang in front of the spine, but rather on a level surface The spine. With a weight of, for example, four to ten kilograms per stand, this aspect is not unimportant.

Bevorzugt verfügt ein Standfuß einer erfindungsgemäßen Sichtblende über ein oder mehrere, Bohrungen in der langgestreckten Platte, damit ein solcher Standfuß ggf. auch am Boden verankert werden kann, bspw. durch Anschrauben, mittels Dübel oder mit Erdspießen. Ferner könnte damit ein Standfuß auch zu Lagerungszwecken fixiert werden, bspw. an einer Fixierstange.A base of a screen according to the invention preferably has one or more bores in the elongated plate, so that such a base can also be anchored to the floor, if necessary, for example by screwing on, by means of dowels or with earth spikes. Furthermore, a base could also be fixed for storage purposes, for example on a fixing rod.

Wenn sich wenigstens eine solche Bohrung in einem Bereich zwischen den Hülsen und einem stirnseitigen Ende befindet, vorzugsweise zwischen den Hülsen einerseits und einem endseitigen Absatz, insbesondere zwischen einem Tragegriff und einem Absatz, so sind die dort anzusetzenden Verankerungsmittel, also Schrauben, Dübel, Erdspieße od. dgl. leicht zugänglich.If there is at least one such bore in an area between the sleeves and an end, preferably between the sleeves on the one hand and an end shoulder, in particular between a handle and a shoulder, the anchoring means to be used there, i.e. screws, dowels, earth spikes or the like easily accessible.

Eine weitere Konstruktionsvorschrift besagt, dass die Stützelemente zumindest jeweils zwei miteinander verbundene, vertikale Stützpfosten aufweisen. Zwischen zwei solchen Stützpfosten lässt sich eine Bahn aus einem undurchsichtigen Werkstoff optimal verankern. Andererseits kann auch ein weiteres Stützelement mit einem seiner Stützpfosten unmittelbar anschließend platziert werden, um einen möglichst lückenlosen Sichtschutz zu erzeugen.Another design specification states that the support elements each have at least two vertical support posts connected to one another. A sheet of opaque material can be optimally anchored between two such support posts. On the other hand, a another support element with one of its support posts can be placed immediately afterwards in order to create a complete privacy screen.

Indem zwei solche Stützpfosten vorzugsweise dauerhaft miteinander verbunden sind, bspw. durch sich dazwischen erstreckende, mit den Stützpfosten verbundene, insbesondere verschweißte, verlötete oder verklebte, horizontal verlaufende Verbindungsholme, ergibt sich eine rahmenförmige Gestalt der Stützelemente, wodurch jene eine hohe Stabilität erfahren.Since two such support posts are preferably permanently connected to one another, for example by connecting brackets extending in between, connected to the support posts, in particular welded, soldered or glued, horizontally extending connecting bars, this results in a frame-like shape of the support elements, which gives them a high degree of stability.

Ferner bieten rahmenförmigen Stützelemente die Möglichkeit, diese innerhalb des Rahmens mit einem Gitter zu versehen, wodurch eine Bahn aus einem undurchsichtigen Material zwischen den Stützpfosten oder sonstigen Teilen des Rahmens nicht sich selbst überlassen ist, sondern sich - insbesondere im Fall einer Windbö - an ein solches Gitter anschmiegen kann.Furthermore, frame-shaped support elements offer the possibility of providing them with a lattice within the frame, as a result of which a sheet of an opaque material between the support posts or other parts of the frame is not left to itself, but rather - in the case of a gust of wind - adheres to one Can nestle mesh.

Eine Bahn aus einem undurchsichtigen Material kann an einem Stützelement dadurch aufgespannt oder verankert werden, dass sie an den vertikalen Stützpfosten und/oder an den horizontalen Verbindungsholmen eines rahmenförmigen Stützelements befestigt wird, beispielsweise mittels in der Bahn angeordnete Löcher oder Ösen durchgreifender Ringe, Schnüre, Drähte od. dgl. Es besteht auch die Möglichkeit, durch eine Reihe von Ösen der undurchsichtigen Bahn einen Spanndraht zu fädeln, welcher dann an dem Stützelement verankert wird.A sheet made of an opaque material can be clamped or anchored to a support element in that it is attached to the vertical support posts and / or to the horizontal connecting bars of a frame-shaped support element, for example by means of rings, cords, wires arranged through holes or eyes in the sheet or the like. There is also the possibility of threading a tension wire through a series of eyelets of the opaque web, which is then anchored to the support element.

Die undurchsichtige Bahn kann aus einem flexiblen Material bestehen, bspw. aus einem Planenmaterial für Lastkraftwagen und/oder aus einem Gewebe, bspw. aus Leinen oder Segeltuch, Hierbei kann es sich um ein leichtes Material handeln, wodurch Gewicht eingespart werden kann, so dass ein einzelnes Stützelement von höchstens zwei Personen oder ggf. sogar von einer einzigen Person transportiert und aufgerichtet werden kann.The opaque web can consist of a flexible material, for example a tarpaulin material for trucks and / or a fabric, for example of linen or canvas. This can be a light material, which can save weight, so that a individual support element can be transported and erected by a maximum of two people or possibly even by a single person.

An einer oder beiden Flächen kann eine solche Bahn mit einer Information versehen sein, bspw. mit Warnsignalen und/oder Warnfarben, oder mit einem Hinweis, vorsichtig weiterzufahren, etc.On one or both surfaces, such a track can be provided with information, for example with warning signals and / or warning colors, or with an instruction to continue carefully, etc.

Um den Spalt zu einer anschließenden Bahn derart überbrücken zu können, dass kein Sichtspalt mehr verbleibt, sieht die Erfindung vor, dass eine Bahn im wenigstens Bereich einer Stoßstelle zwischen benachbarten Stützelementen wenigstens einen Überlappungsbereich aufweist. Dieser kann bspw. dem Verlauf eines vertikalen Stützpfostens folgen mit einer Breite von einigen Zentimetern, beispielsweise fünf bis zwölf Zentimetern, und reicht dadurch bis zu einem benachbart eingesteckten Stützpfosten.In order to be able to bridge the gap to a subsequent web in such a way that there is no longer any viewing gap, the invention provides that a web has at least one overlap region in at least one area of a joint between adjacent support elements. This can, for example, follow the course of a vertical support post with a width of a few centimeters, for example five to twelve centimeters, and thus extends to an adjacent support post.

Schließlich entspricht es der Lehre der Erfindung, dass ein Überlappungsbereich mittels einer Klettverbindung an einer anschließenden Bahn festlegbar ist. Dadurch ergibt sich einerseits eine lückenlose Sichtblende; andererseits erhält man auch eine durchgehende Fläche, die mit einer die verschiedenen Stützelemente übergreifenden Information bedruckt sein kann, bspw. mit einer an die vorbeifahrenden Verkehrsteilnehmer gerichteten Botschaft in großen Buchstaben.Finally, it corresponds to the teaching of the invention that an overlap area can be defined on a subsequent web by means of a Velcro connection. On the one hand, this results in a complete screen; on the other hand, a continuous surface is also obtained, which can be printed with information spanning the various support elements, for example with a message in large letters directed at the passing road users.

Ferner zeichnet sich die Erfindung aus durch einen Standfuß für eine Sichtblende zum Abschirmen von Unfällen, mit rahmenförmigen Stützelementen, die zumindest jeweils zwei miteinander verbundene, vertikale Stützpfosten aufweisen und mit einer flexiblen Bahn aus einem undurchsichtigen Material bespannt oder bespannbar sind und in Stützfüßen gehalten werden, wobei der Standfuß eine langgestreckte Platte aufweist sowie vier von dieser langgetreckten Platte nach oben ragende Hülsen mit vertikaler Längsachse zum Einstecken je eines vertikalen Stützpfostens eines rahmenförmigen Stützelements. Ein solcher Standfuß ist für eine Sichtblende von zentraler Bedeutung, da er jener auch bei stürmischem Wetter eine ausreichende Stabilität geben soll.Furthermore, the invention is characterized by a base for a screen for shielding from accidents, with frame-shaped support elements which each have at least two interconnected vertical support posts and are covered or can be covered with a flexible sheet made of an opaque material and are held in support feet, wherein the base has an elongated plate and four sleeves projecting upward from this elongated plate with a vertical longitudinal axis for inserting a vertical support post of a frame-shaped support element. Such a stand is of central importance for a screen, since it should give it sufficient stability even in stormy weather.

In Fig. 1 ist beispielhaft für die vorliegende Erfindung eine wandförmige Sichtblende 1 dargestellt, die bevorzugt zum Abschirmen von Unfällen gegenüber Schaulustigen zum Einsatz gelangen kann.In Fig. 1 a wall-shaped screen 1 is shown as an example of the present invention, which can preferably be used to shield accidents from onlookers.

Dis Sichtblende 1 umfasst eine Stützkonstruktion 2 aus mehreren Stützelementen 3, welche modulartig miteinander kombiniert werden können.The screen 1 comprises a support structure 2 comprising a plurality of support elements 3, which can be combined with one another in a modular manner.

Jedes Stützelement 3 hat eine rahmeriförmige Gestalt und umfasst vertikale Stützpfosten 4 sowie horizontale Verbindungsholme 5. Bevorzugt weist jedes Stützelement 3 die Gestalt eines vertikalen Rechteckrahmens auf, mit einem ersten Stützpfosten 4 am linken Rand und einem zweiten Stützpfosten 4 am rechten Rand, welche durch einen oberen Verbindungsholm 5 und durch einen unteren Verbindungsholm 5 miteinander verbunden sind, vorzugsweise untrennbar miteinander verbunden sind, bspw, miteinander verschweißt, verlötet oder verklebt sind.Each support element 3 has a frame-like shape and comprises vertical support posts 4 and horizontal connecting bars 5. Preferably, each support element 3 has the shape of a vertical rectangular frame, with a first support post 4 on the left edge and a second support post 4 on the right edge, which is represented by an upper one Connecting bar 5 and are connected to one another by a lower connecting bar 5, preferably are inseparably connected to one another, for example welded, soldered or glued to one another.

Ferner kann ein solches rahmenförmiges Stützelement 3 innerhalb des von den vertikalen Stützpfosten 4 und den horizontalen Verbindungsholmen 5 aufgespannten Rahmens noch eine Füllung aufweisen, bspw. aus einer Art Matte oder Geflecht von einander vorzugsweise rechtwinklig überkreuzenden Metalldrähten, die bevorzugt miteinander und/oder mit den Stützpfosten 4 und Verbindungsholmen 5 verbunden sind, beispielsweise verschweißt, verlötet oder verlebt.Furthermore, such a frame-shaped support element 3 within the frame spanned by the vertical support posts 4 and the horizontal connecting bars 5 can also have a filling, for example made of a type of mat or mesh of metal wires that preferably cross at right angles, preferably with one another and / or with the support posts 4 and connecting bars 5 are connected, for example welded, soldered or glued.

Ein solches Stützelement 3 aus Stützpfosten 4, Verbindungsholmen 5 sowie ggf. einer Füllung bspw. in Form einer Matte oder eines Geflechts ist sodann mit einer Bahn 6 aus einem undurchsichtigen Material bespannt oder bespannbar. Es kann sich hierbei um eine Plane handeln, nach Art einer Plane für einen Lastkraftwagen, oder um ein Gewebe, bspw. aus Leinen oder Segeltuch; es ist aber auch denkbar, hierfür eine dünne Plastikplatte zu verwenden.Such a support element 3 comprising support posts 4, connecting bars 5 and, if appropriate, a filling, for example in the form of a mat or a mesh, is then covered or can be covered with a web 6 made of an opaque material. This can be a tarpaulin, in the manner of a tarpaulin for a truck, or a fabric, for example made of linen or canvas; but it is also conceivable to use a thin plastic plate for this.

Wie der Zeichnung weiter zu entnehmen ist, ruhen die Stützelemente 3 auf Standfüßen 7, von denen sie zuverlässig gehalten werden.As can be seen from the drawing, the support elements 3 rest on feet 7, by which they are held reliably.

Jeder Standfuß 7 weist eine langgestreckte Platte 8 auf, vorzugsweise aus Metall, insbesondere aus verzinktem Eisen oder Stahl. Die Länge der Platte 8 liegt beispielsweise zwischen einem Viertel und drei Vierteln der Höhe der undurchsichtigen Bahn 6 bzw. dem vertikalen Abstand zwischen oberstem und unterstem Verbindungsholm 5, vorzugsweise zwischen einem Drittel und zwei Dritteln der Höhe der undurchsichtigen Bahn 6 bzw. dem vertikalen Abstand zwischen oberstem und unterstem Verbindungsholm 5.Each stand 7 has an elongated plate 8, preferably made of metal, in particular made of galvanized iron or steel. The length of the plate 8 is, for example, between a quarter and three quarters of the height of the opaque web 6 or the vertical distance between the top and bottom connecting bar 5, preferably between one third and two thirds of the height of the opaque web 6 or the vertical distance between top and bottom connecting bar 5.

Fig. 4 zeigt den Zuschnitt der Platte 8, wonach seine Länge etwa vier- bis sechsmal so groß ist wie seine Breite. Die Ecken 9 können abgerundet sein, um die Verletzungsgefahr zu minimieren. Fig. 4 shows the cut of the plate 8, after which its length is about four to six times as large as its width. The corners 9 can be rounded in order to minimize the risk of injury.

Die Platte 8 kann völlig eben sein, wodurch die Herstellung weiter vereinfcht ist. Da ein Biegeschritt nicht erforderlich ist, kann die Dicke der Platte 8 etwas größer gewählt werden, beispielsweise 3 mm oder mehr, vorzugsweise 5 mm oder mehr, insbesondere 7 mm oder mehr, oder sogar 9 mm oder mehr.The plate 8 can be completely flat, which further simplifies the manufacture. Since a bending step is not required, the thickness of the plate 8 can be chosen to be somewhat larger, for example 3 mm or more, preferably 5 mm or more, in particular 7 mm or more, or even 9 mm or more.

Im zentralen Bereich der Platte 8 befinden sich auf deren Oberseite 10 mehrere, vorzugsweise vier nach oben ragende Hülsen 11 mit vertikaler Längsachse zum Einstecken je eines vertikalen Stützpfostens 4 eines rahmenförmigen Stützelements 3.In the central area of the plate 8 there are a plurality, preferably four, upwardly projecting sleeves 11 with a vertical longitudinal axis for inserting a vertical support post 4 of a frame-shaped support element 3 on the upper side 10 thereof.

Vorzugsweise sind die Hülsen 11 allesamt gleich lang und können mit einer Stirnseite auf der Oberseite 10 stumpf aufgesetzt sein und dort - beispielsweise mit einer rundum laufenden Schweißnaht 12 - fixiert sein.The sleeves 11 are preferably all of the same length and can be butt-fitted with an end face on the top 10 and fixed there - for example with a weld seam 12 running all around.

Unterhalb jeder Hülse 11 ist die Platte 8 vorzugsweise mit je einer Ausnehmung 13 versehen, so dass aus jeder Hülse 11 Regenwasser od. dgl. jederzeit abfließen kann. Allerdings sollte der Durchmesser einer solchen Ausnehmung 13 kleiner sein als der Innendurchmesser der betreffenden Hülse 11 und auch kleiner als der Außendurchmesser eines darin einzusteckenden Stützpfostens 4 im Bereich von dessen unterem Ende, beispielsweise wenigstens 1 mm kleiner, bevorzugt wenigstens 2 mm kleiner, insbesondere wenigstens 3 mm kleiner als der Außendurchmesser des unteren Endes eines einzusteckenden Stützpfostens 4, damit ein Stützpfosten 4 nicht gänzlich durch den Standfuß 7 hindurchrutschen kann, sondern auf dem die Ausnehmung 1 umgebenden Rand der Platte 8 aufsteht und also das anteilige bzw. halbe Gewicht des betreffenden Stützelements 3 auf die Platte 8 beschwerend einwirkt und dadurch einem unerwünschten Kippen oder Verrutschen des betreffenden Standfußes 7 entgegenwirkt.Below each sleeve 11, the plate 8 is preferably provided with a recess 13, so that rainwater or the like can flow out of each sleeve 11 at any time. However, the diameter of such a recess 13 should be smaller than the inner diameter of the sleeve 11 in question and also smaller than the outer diameter of a support post 4 to be inserted therein, in the region of its lower end, for example at least 1 mm smaller, preferably at least 2 mm smaller, in particular at least 3 mm smaller than the outer diameter of the lower end of a support post 4 to be inserted, so that a support post 4 cannot slide completely through the base 7, but instead stands on the edge of the plate 8 surrounding the recess 1 and therefore the proportionate or half the weight of the support element 3 concerned acts on the plate 8 in a weighting manner and thereby counteracts an undesired tilting or slipping of the relevant base 7.

Wie man der Zeichnung weiter entnehmen kann, sind alle Hülsen 11 an den Ecken eines Quadrats angeordnet, welches ähnlich einer Raute derart zu der Platte 8 ausgerichtet ist, dass eine Diagonale dieses Quradrats parallel zu einer Längskante 14 der Platte 8 verläuft, während die andere Diagonale des Quadrats parallel zu einer kurzen Stirnkante 15 der Platte 8 verläuft.As can be seen from the drawing, all sleeves 11 are arranged at the corners of a square, which is aligned to the plate 8 in a manner similar to a rhombus in such a way that a diagonal of this square is parallel to a longitudinal edge 14 of the plate 8, while the other diagonal of the square runs parallel to a short end edge 15 of the plate 8.

Wie man der Fig. 1 entnehmen kann, wird im Normalfall, also wenn sich an einem Standfuß 7 nur zwei Stützelemente 3 treffen, die Längsachse bzw. eine Längskante 14 des dortige Standfußes 7 in Richtung bzw. parallel zu der Winkelhalbierenden zwischen den zusammentreffenden Stützelemente 3 ausgerichtet, bzw., wenn jene in einer geraden Fluchtlinie orientiert sind, lotrecht zu eben jener Fluchtlinie. Es wäre bei Bedarf allerdings auch möglich, den Standfuß 7 anders auszurichten, bspw. parallel zu dem Verlauf der Sichtblende 1, wobei dann allerdings die durch den betreffenden Standfuß 7 vermittelte Standfestigkeit vermindert sein kann. Ein Kompromiss besteht darin, zwei unmittelbar benachbarte Hülsen 11 zu verwenden, so dass der Standfuß 7 mit der Linie der angrenzenden Stützelemente 3 etwa einen Winkel von 45° einschließt.How to Fig. 1 can be seen, in the normal case, i.e. when only two support elements 3 meet on a base 7, the longitudinal axis or a longitudinal edge 14 of the base 7 there is aligned in the direction or parallel to the bisector between the encountering support elements 3, or if those are oriented in a straight line of alignment, perpendicular to that same line of alignment. If necessary, however, it would also be possible to align the base 7 differently, for example parallel to the course of the screen 1, but the stability imparted by the base 7 in question can then be reduced. A compromise is to use two immediately adjacent sleeves 11 so that the base 7 forms an angle of approximately 45 ° with the line of the adjacent support elements 3.

Wie die Platte 8, so können auch die Hülsen 11 korrosionshemmend ausgebildet oder behandelt sein, bspw. verzinkt.Like the plate 8, the sleeves 11 can also be designed to be corrosion-resistant or treated, for example galvanized.

Weitere, wichtige Bestandteile des Standfußes 7 sind zwei Beläge 16 aus einem rutschhemmenden Material an seiner Unterseite 17, vorzugsweise im Bereich seiner beiden kurzen Stirnkanten 15.Further, important components of the base 7 are two coverings 16 made of an anti-slip material on its underside 17, preferably in the region of its two short end edges 15.

Ein solcher rutschhemmender Belag 16 sollte durchaus eine erkennbare Dicke von wenigstens einigen Millimetern aufweisen, bspw. zwischen 5 mm und 25 mm, insbesondere zwischen 10 mm und 20 mm, so dass bei einem ebenen oder nur leicht unebenen Untergrund der mittlere Bereich 18 der Unterseite 17 zwischen den beiden, endseitigen Belägen 16 vom Boden abgehoben ist und das gesamte Gewicht des Standfußes 7 samt eingesteckter Stützpfosten 4 auf den beiden endseitigen Belägen 16 ruht.Such a slip-resistant covering 16 should definitely have a recognizable thickness of at least a few millimeters, for example between 5 mm and 25 mm, in particular between 10 mm and 20 mm, so that the middle region 18 of the underside 17 on a flat or only slightly uneven surface between the two end-facing coverings 16 is lifted off the floor and the entire weight of the base 7 including the inserted support post 4 rests on the two end-facing coverings 16.

Die Beläge 16 können bspw. aus Hartgummi bestehen, und/oder aus einem Material, wie es auch für Autoreifen verwendet wird. Ferner kann eine Profilierung vorgesehen sein, bspw. mit Rillen 19, welche einander bevorzugt überkreuzen, so dass zwischen diesen Rillen ein Raster von erhabenen Bereichen 20 verbleibt. Andere Profile sind denkbar, vergleichbar mit dem Profil an der Lauffläche eines Fahrzeugreifens.The linings 16 can consist, for example, of hard rubber and / or of a material such as is also used for car tires. Furthermore, profiling can be provided, for example with grooves 19, which preferably cross each other, so that a grid of raised areas 20 remains between these grooves. Other profiles are conceivable, comparable to the profile on the tread of a vehicle tire.

Eine weitere Besonderheit eines erfindungsgemäßen Standfußes 7 ist, dass die Platte 8 ein oder mehrere, vorzugsweise zwei durchgehende Ausnehmungen 21 aufweist. Eine solche Ausnehmung 21 kann nahe eines endseitigen Belags 16 angeordnet sein, und sie kann bevorzugt dazu verwendet werden, den betreffenden Standfuß 7 auf einem Untergrund zu fixieren.Another special feature of a stand 7 according to the invention is that the plate 8 has one or more, preferably two, continuous recesses 21. Such a recess 21 can be arranged near an end covering 16, and it can preferably be used to fix the relevant base 7 on a surface.

Damit ein Standfuß 7 leicht ergriffen werden kann, bspw. um an Ort und Stelle aufgestellt zu werden, verfügt er außerdem über einen oder mehrere, vorzugsweise zwei Tragegriffe 22.So that a stand 7 can be easily gripped, for example to be set up on the spot, it also has one or more, preferably two, handles 22.

Wie Fig. 2 erkennen lässt, gibt es vorzugsweise zwei Tragegriffe 22, und zwar zu beiden Seiten der mittig angeordneten Hülsen 11, in einem Abstand zu jenen von etwa 2 cm bis 15 cm, vorzugsweise in einem Abstand von etwa 5 cm bis 10 cm.How Fig. 2 shows, there are preferably two handles 22, namely on both sides of the centrally arranged sleeves 11, at a distance from them of about 2 cm to 15 cm, preferably at a distance of about 5 cm to 10 cm.

Jeder Tragegriff 22 hat eine etwa U-förmige Gestalt mit zwei Seitenschenkeln 23, welche durch einen dazu lotrechten Mittelsteg 24 miteinander verbunden sind.Each handle 22 has an approximately U-shaped shape with two side legs 23 which are connected to one another by a central web 24 perpendicular thereto.

Vorzugsweise sind die Seitenschenkel 23 kürzer als der Mittelsteg 24. Die freien Enden der Seitenschenkel 23 sind bevorzugt an der Oberseite 10 der Platte 8 festgelegt, insbesondere angeschweißt, ggf. auch in dortigen Ausnehmungen 25 in der Oberseite 10 der Platte 8 eingesteckt und sodann befestigt, bevorzugt angeschweißt.The side legs 23 are preferably shorter than the central web 24. The free ends of the side legs 23 are preferably fixed, in particular welded, to the top 10 of the plate 8, possibly also inserted into the recesses 25 in the top 10 of the plate 8 and then fastened, preferably welded on.

Bevorzugt ist der fertig zusammengebaute Standfuß 7 (mit Ausnahme der Beläge 16 aus einem rutschhemmenden Material) galvanisiert oder verzinkt oder mit einem sonstigen, korrosionshemmenden Überzug versehen.The fully assembled base 7 (with the exception of the pads 16 made of an anti-slip material) is preferably galvanized or galvanized or provided with another, corrosion-resistant coating.

Die Fig. 1 zeigt als eine weitere Besonderheit, dass an einer Bahn 6 aus einem undurchsichtigen Material entlang einer vertikalen Kante ein laschenartiger Ansatz 26 vorgesehen sein kann, welcher dem Zweck dient, den Spalt zwischen zwei Stützpfosten 4 benachbart in den selben Standfuß 7 verankerter Stützelemente 3 zu überdecken, so dass der Sichtschutz lückenlos ist. Ferner kann Im Bereich der freien Kante 27 eines solchen laschenartigen Ansatzes 26 ein Klettelement angeordnet sein, als Pendant zu einem anderen lettelement im Bereich der gegenüber liegenden Kante 28 der Bahn 6 des betreffenden Stützelements 3. Bei Verwendung allesamt gleichartiger Sichtschutzelemente 1 findet dann ein Klettelement im Bereich der freien Kante 27 des laschenartigen Ansatzes 26 ein passendes Pendant entlang der ihm zugewandten, freien Kante 28, so dass sich durch das Zusammenfügen dieser Klettelemente eine durchgehende Sichtschutzwand ergibt, die ggf. auch zum Übertragen von Botschaften bedruckt sein könnte.The Fig. 1 shows as a further peculiarity that a tab-like extension 26 can be provided on a web 6 made of an opaque material along a vertical edge, which serves the purpose of covering the gap between two support posts 4 adjacent to anchored support elements 3 in the same base 7, so that the privacy screen is complete. Furthermore, a Velcro element can be arranged in the area of the free edge 27 of such a tab-like extension 26, as a counterpart to another Latv element in the area of the opposite edge 28 of the web 6 of the support element 3 concerned In the area of the free edge 27 of the tab-like extension 26, a suitable counterpart along the free edge 28 facing it, so that the joining of these Velcro elements results in a continuous screen wall, which could possibly also be printed for the transmission of messages.

Bevorzugt hat die Platte 8 eines Standfußes 7 etwa eine Länge von 800 mm bis 1.200 mm, und/oder etwa eine Breite von 100 mm bis 200 mm und/oder eine Stärke von 10 mm bis 20 mm. Das Gewicht eines erfindungsgemäßen Standfußes 7 beträgt dann etwa 15 kg bis 25 kg.
