Definitions
- the present invention relates to a post system for fastening posts to a substrate.
- posts are also to be understood as rods, stands or the like.
- these are barrier posts, bollards, railings, fall protection, signposts, brackets for signs or rubbish bins, or bike racks.
- the underground can be, for example, a roadway, a sidewalk or a square, outdoors or inside a building.
- a barrier post system is known in which a post is detachably arranged in a floor anchorage and held by the latter by a bayonet lock.
- a locking mechanism prevents unauthorized persons from removing the barrier post.
- a disadvantage of such a system is that the insertion of the post requires correct alignment of the locking elements of the bayonet catch. To do this, the post must first be placed on the floor anchor and then a correct position must be found by rotating the post.
- the ground anchoring of such a system is susceptible to contamination, which has a detrimental effect on the insertion and locking of the post.
- Another disadvantage is the rigid connection between the post and the ground anchorage, since this leads to the fact that at least the fastening elements of the bayonet lock are destroyed when a force is applied to the post.
- the fastening elements In order to reduce the destruction to the fastening elements as much as possible, the fastening elements have predetermined breaking points.
- Such a fastener in the form of a screw is made the CH 707 526 known.
- the disadvantage of such a screw is that it is complex to manufacture or rework.
- the driving profile reaching through the head into the threaded shaft causes an additional weakening, which leads to a greatly reduced screw strength.
- the post is detachably arranged in the floor anchor, the post being rotatably arranged by means of a lock located on the underside of this on a counter lock assigned to the upper side of the floor anchor.
- the posts and ground anchors can be metal, such as steel, stainless steel, aluminum, or the like, or plastic or composite, or a combination thereof.
- a lock can be provided at the top and a bolt that is in operative connection therewith by a tension element, which in the closed position penetrates the lock and engages in a bolt receiving recess in the ground anchorage.
- the lock is releasably connected to the counter lock by a plug-and-turn connection, such as a bayonet lock or a Storz coupling.
- the closure of the post also has a centrally arranged guide pin with a central shaft on the underside, and the floor anchorage also has a central recess on the upper side with a central bore complementary to the central shaft.
- the guide mandrel has at least one outwardly to the side of the shaft protruding elevation and the central recess has at least one radial recess which is complementary to the elevation and which extends outwardly to the side of the central bore.
- the guide pin is made longer than the closure elements and this protrudes in the insertion direction.
- the design of smooth transitions between the central shaft of the guide mandrel and the elevations provided on it, as well as between the central bore of the counter-lock and the radial recesses adjoining this, is also advantageous, since the alignment then takes place almost automatically with little effort .
- the guide mandrel preferably has a tip which is implemented by conically converging the circumference of the shaft. There is no elevation in the area of the tip. An area with the at least one elevation adjoins the top. Alternatively, there can be two, three, four or more elevations. The number of elevations on the guide pin preferably corresponds to the number of radial recesses in the counter lock. However, an unequal number is also conceivable.
- the area with the at least one elevation is followed by a shaft area which has no elevations. This area enables the guide pin, and thus the entire closure, to be rotatable after being inserted into the counter-closure.
- the counter-lock has an upper-side area with the recesses complementary to the guide pin, and an underlying area which is designed in such a way that it does not prevent the guide pin with its elevations from rotating about its longitudinal axis.
- the at least one radial recess is designed in such a way that, when the guide pin is inserted into the central recess, it acts as a Guide for the at least one elevation is used and serves as a bolt receiving recess after the plug-in-turn connection has been established. That is, after the rotation into the closed position, the bolt engages in one of the at least one radial recesses.
- the longitudinal center axis of the bolt lies on a circle around the longitudinal center axis of the guide mandrel which lies within the area of the radial recesses. This embodiment has the advantage that no additional recesses have to be provided for receiving the bolt in the counter lock.
- the bolt can be arranged in such a way that its longitudinal center axis lies on a circle around the longitudinal center axis of the guide mandrel, which lies within the area of peripheral recesses which are provided for receiving closure elements.
- the bolt In the locked state of the post, the bolt is preferably located in an insertion area of the peripheral recesses, since this is only occupied by the locking elements during the insertion of the locking elements of the post into the counter-lock and is unoccupied in the locked state.
- the arrangement of the bolt in a peripheral area has the advantage that larger torques can be absorbed, which act on the post about its longitudinal center axis or that of the guide pin.
- a displaceable locking core is preferably arranged in the floor anchorage, which, when not connected to the post, closes the recesses on the upper side of the floor anchorage and which can be pressed down by the guide pin and / or other elements of the plug-and-turn connection. Closing the recesses on the top prevents the floor anchoring from becoming clogged. For example, leaves, snow or ice are prevented from clogging the recesses and thus making it more difficult to insert the post.
- the locking core can be made of metal or plastic.
- a metal locking core is particularly wear-resistant, which means that a long service life can be achieved.
- a metal locking core is made of stainless steel or aluminum.
- a closure core made of plastic has the advantage that the plastic has a different coefficient of thermal expansion than the housing of the mating closure that surrounds it. This prevents or reduces the risk of icing at temperatures around or below freezing point.
- a closure core is based on a polycarbonate mixture.
- the closure core is advantageously pressed upwards into the recesses located on the top by a spring element. For example, by a spiral or leaf spring or other spring elements known from the prior art.
- the closure can have a centrally arranged guide pin and preferably at least one elevation protruding laterally outward from the shaft.
- the closure preferably has at least one claw as an element of the plug-and-turn connection.
- Other known locking elements such as for bayonet locks or Storz couplings, such as a combination of slot and bolt, can also be used.
- the guide mandrel has a cable receptacle in its interior in the form of a bore, which extends from the side of the closure opposite the guide mandrel along the longitudinal axis of the guide mandrel into the latter, with receptacles on the guide mandrel for elements for attaching a restraint rope in the rope holder are provided.
- the restraint rope has the advantage that if the lock is separated from the rest of the post, the lock still remains connected to the rest of the post, so that if the lock is still locked in the mating lock, the rest of the post does not move freely from the mating lock or . can remove the floor anchor.
- a locking pin is preferably provided in the closure, which locks with the counter-closure when the closure from the rest of the post, ie from the bottom of the The post is separated.
- the floor anchorage according to the invention can also be made with posts, rods, stands or the like known from the prior art, in particular Use barrier posts, such a ground anchorage having a counter-lock located on the top of this having a centrally arranged recess with a central bore, the central recess having at least one radial recess which extends outwardly to the side of the central bore.
- Use barrier posts such a ground anchorage having a counter-lock located on the top of this having a centrally arranged recess with a central bore, the central recess having at least one radial recess which extends outwardly to the side of the central bore.
- the floor anchorage preferably also has at least one peripheral recess on the upper side as an element of the plug-and-turn connection, which has an insertion area and a closure area, the insertion area being wider than the closure area in the radial direction.
- a displaceable locking core is arranged in the stand-alone floor anchorage, through which the recesses located on the top of the floor anchorage can be closed upwards and which is held in a position closing the recesses by a spring element.
- a post system can have at least one fastening element, a first receptacle on the closure and a second receptacle on the bottom for fastening the closure to the bottom of the post, each fastening element being received on one side in the first receptacle and on its other side in the second recording is recorded.
- the fastening element has a longitudinal axis and the closure and the base are braced against one another in the direction of the longitudinal axis.
- the second receptacle is preferably movable essentially in the direction of the longitudinal axis in a predetermined range. This leads to a limited resilience of the second receptacle, which has the advantage that the forces acting on the fastening element or elements are dampened and thus damage to the fastening elements can be reduced.
- the base preferably has a passage for each fastening element and the second receptacle has at least one guide element which is arranged around each passage, with at least one fixation and at least one spring element for the corresponding fastening element in each guide element are led.
- Cages or sleeves are suitable as guide elements, nuts, split pins or bolts, for example, as fixings, and tension, compression or disc springs, for example, as spring elements.
- the at least one spring element is preferably arranged between the floor and the at least one fixation. With such an arrangement, the fixation is pushed away from the floor by the spring element and there is an increase in the force acting on the fixation when the fixation is shifted in the direction of the floor.
- the above-mentioned fastening element is designed as a predetermined breaking screw for fastening the closure to a bottom of the post, which has a threaded shaft with an external thread and a head with a driving profile, the predetermined breaking screw having a predetermined breaking point area on the threaded shaft, with the Head opposite side of the predetermined breaking point area, adjoining this at least one recess is formed.
- the predetermined breaking screw is intended to prevent the closure from being damaged if a permissible force is exceeded.
- the predetermined breaking point area ensures that the predetermined breaking screw breaks before the closure is damaged. After the head of the screw has been separated from the threaded shaft, it is important that the threaded shaft can still be removed.
- the at least one recess is provided on the threaded shaft.
- the predetermined breaking point area is preferably formed adjacent to the head. This arrangement ensures that, after the head has been separated, the recess is accessible from the direction in which the head was previously located. A tool can be used to reach into this recess in order to remove the threaded shaft.
- two, three, four, five, six or more recesses can be provided.
- six recesses can be designed in such a way that a conventional hexagon can be used to unscrew the threaded shaft.
- a plurality of recesses can be provided, which are designed as Torx, for example.
- the at least one recess is of this type designed that it penetrates the threaded shaft transversely to its longitudinal center axis. If the head is then separated, a slot is created which extends transversely through the threaded shaft.
- a conventional slotted screwdriver can then be used as a tool.
- the Figure 1 shows a perspective view of a post system according to the invention before the introduction of a barrier post 1 into a ground anchorage 2.
- the barrier post 1 has a tube 10, a bottom 11 closing the tube 10 in the lower area, a lock 12 arranged on the bottom 11, and a tube 10 in the upper area closing lid 13.
- An intermediate piece 14 can optionally be arranged between the cover 13 and the upper end of the post 1.
- the intermediate piece 14 is an annular component and at its one end connects essentially seamlessly to the tube 10 of the post 1 and has a receptacle for the cover 13 at its other end.
- Recesses 140 are provided in the intermediate piece 14. These recesses 140 can be used to accommodate a chain, for example, which has the advantage that no eyelets are required on the post.
- the construction with the recesses 14 is more economical than that with eyelets attached to the tube of the post.
- such a cover 13 can also be used without chains, without eyelets protruding from and protruding from the post side in a disruptive manner.
- a lock 8 is arranged in an upper area, which can be operated from the outside and into which a key 80 can be inserted for actuation.
- the lock 80 is operatively connected to a locking bolt 7 via a locking rod 70.
- the second receptacles 30 for receiving the fastening elements 4 of the closure 12 are shown.
- the Figure 2 shows a partial sectional view of the post system through a locking bolt 7 and a fastening element in the form of a predetermined breaking screw 4 with the barrier post 1 inserted.
- claws 122 of the closure 12 form a form-fitting connection with a correspondingly complementary geometry on the mating closure 20.
- the insertion area 2010 of the peripheral recesses 201 is released in the closed state, ie there is no claw 122 in the area.
- the guide pin 121 is guided in the ground anchorage 2 through a central bore 2020 in a central recess 202.
- the locking bolt 7 is guided in a locking bolt passage 110 in the base 11 and in a collinear passage 127 in the lock 12 and engages in a radial recess 2021 of the central recess 202 in the counter lock 20
- Lock 8 can be actuated, whereby the locking bolt 7 is pulled out of the radial recess 2021 by means of the locking rod 70.
- the locking bolt 7 can be arranged in such a way that it can engage in one of the peripheral recesses 201. If the locking bolt 7 is arranged in the radius further away from the center, the larger torques can be absorbed with the same bolt, or a smaller bolt can be used to absorb the same torque.
- the barrier post 1 In its lower region, the barrier post 1 has a base 11 which is let into the pipe 10 and is firmly connected to it.
- the closure 12 is arranged below the base 11 and adjoining it in alignment.
- the closure 12 is firmly mounted on the base 11 by means of a fastening 3, the fastening 3 having a first receptacle 123 on the closure 12, a second receptacle 30 on the base 11 and a predetermined breaking screw 4. Details of the closure 12 are in FIGS Figures 3 and 4 shown, details of the second receptacle 30 in FIG Figure 7 and details of the break screw in the Figure 8 .
- the head 42 of the predetermined breaking screw 4 is in the first The receptacle 123 is arranged on the closure 12.
- the first receptacle 123 shown here is a countersunk hole which has the countersink on the side of the closure 12 on which the guide pin 121 is arranged. It can thus be avoided that the screw 4 protrudes from an underside of the closure 12.
- a passage 111 is provided in the base 11, which has a diameter that is essentially the same as the countersunk bore 123 in the closure 12. The diameter is dimensioned such that there is sufficient lateral play for the tube 10 with the base 11 with respect to the closure 12 can be inclined by up to 15 degrees, preferably up to 10 degrees, preferably up to 8 degrees, without the screw jamming.
- the second receptacle 30 is arranged on the floor 11.
- the second receptacle 30 has guide elements 31 in the form of threaded bolts.
- Three such threaded bolts 31 are each arranged around a through hole 111 of a predetermined breaking screw 4.
- a stack of disc springs 35 is arranged between the three threaded bolts 31 and is guided laterally through the threaded bolts 31.
- a screw nut 34 which serves as a fixation 34 for the predetermined breaking screw 4, is arranged on the cup spring stack 35.
- a stop plate 32 is provided above the screw nut 34, which supports the nut 34 upwards and at the same time serves as an anti-twist device for the nut 34.
- the stop plate 32 is secured by nuts 33 which are screwed tight to the free ends of the threaded bolts 31.
- a predetermined breaking screw 4 can be inserted through the first receptacle 123 in the closure 12, pushed through the passage 111 in the base 11 until it reaches the nut 34, where it can be screwed in. The more the screw 4 is tightened, the more the plate springs 35 are compressed and the greater the clamping force. The screw 4 is not fully tightened, so that a lifting of the base 11 of up to 15 millimeters, preferably up to 10 millimeters, preferably up to 8 millimeters with respect to the closure 12 is possible. If the distance between the base 11 and the lock 12 increases, the clamping force increases until all the cup springs are completely compressed.
- the three second recordings 30 are arranged regularly, ie at an angle of 120 degrees to one another with respect to the central axis of the base 11 around this.
- FIG. 13 shows a perspective bottom view of a closure 12 and FIG Figure 4 a corresponding top view.
- the closure 12 essentially has a circular disk 120 which is essentially flat on its upper side and which has a guide pin 121 formed on its underside in the extension of the disk center axis, which extends downward away from the disk 120.
- the guide mandrel 121 essentially has the shape of an arrowhead with a bolt-shaped shaft 1210, which has a conically converging tip 1211 at its free end, ie on the opposite side of the disk 120. Adjacent to the tip 1211, three wing-shaped elevations 1212 are arranged rotationally symmetrically with respect to the central axis of the guide mandrel 121 or the disk 120.
- the elevations 1212 are in the form of wings, the radial extension of which increases continuously from the tip towards the disk 120 until it reaches a value which corresponds approximately to the radius of the shaft 1210.
- the diameter of the shaft 1210 measures 5 to 20 millimeters, preferably 8 to 15 millimeters. That is to say, the elevations 1212 extend in cross section from the center of the shaft 5 to 35 millimeters, preferably 10 to 25 millimeters, radially outward.
- the angle between the longitudinal center axis of the shaft 1210 and the outer contour of the elevations 1212 is between 8 and 20 degrees, preferably 10 to 15 degrees. The expansion then decreases again, so that between the area with the elevations 1212 and the disk 120 there is an area that has no elevations.
- the decrease in expansion toward disk 120 is greater than the increase toward the tip side.
- the angle between the outer contour of the surname and the outer contour of the decrease is 90 to 150 degrees, preferably 110 to 130 degrees.
- the width of the individual elevations in cross section measure 3 to 10 millimeters, preferably 5 to 8 millimeters.
- the length of the area without an elevation is coordinated with the thickness of the support plate 203 of the counter-lock 20 and measures 10 to 50 millimeters, preferably 15 to 35 millimeters.
- a cable receptacle 126 Arranged from the top of the disk 120 is a cable receptacle 126 in the form of a bore, which extends from the top on the center axis of the disk 120 into the Guide mandrel 121 extends into it.
- threaded bores 124 are provided, into which screw elements for clamping a wire rope can be screwed.
- each claw 122 is an elevation 1220 extending from the disk 120 parallel to its axis of rotation and has essentially the shape of a ring segment in a cross section parallel to the disk 120.
- the radial dimension of each ring segment is 5 to 15 millimeters, preferably 5 to 10 millimeters.
- the radial dimension in the area of the elevations 1220 is essentially twice as large as that of the ring segments, i.e. 5 to 30 millimeters, preferably 10 to 20 millimeters.
- a free end of the claw converges towards the free end in the circumferential direction.
- the free end has chamfers 1223 on both sides in the circumferential direction.
- the claw In an area adjoining the disk 120, the claw has a recess 1221 on the side directed outward in the radius, so that the claw is made thinner in the radius direction in this area.
- a surface of the recess 1221 directed towards the disk 120 is configured parallel to the disk 120 and a closure surface 1222 of the recess 1221 opposite this surface is configured helically.
- the helical shape causes the locking surface 1222 of the post to be braced against a corresponding locking surface 2013 of the counter-lock 20 when the post is tightened, i.e. when the post is rotated.
- the closure surface 1222 can also be formed parallel to the pane 120. As long as at least one of the closure surfaces 1222, 2013 is helical, tensioning takes place when the post is tightened.
- Three countersunk bores 123 distributed rotationally symmetrically are formed in the disk 120, the countersinks being formed on the underside, ie on the side of the guide mandrel 121. Furthermore, a through-hole 127 and a locking pin receptacle 125 are arranged in the disk 120, the longitudinal center axes of which are located on a common circle around the disk center.
- the through-hole 127 has a diameter which is matched to the diameter of the locking bolt 7 that it is easily in the Through hole 127 can be performed.

- the diameter of the bolt 90 and the receptacle 125 are matched to one another in such a way that, in the exception 125, the bolt 90 falls downwards under the action of gravity. Ie the bolt is loose in the mount.
- the floor anchor 2 as shown in the Figure 2 is shown in a sectional view, has a counter-closure 20, which forms a complementary counterpart to the closure 12. Individual times of the counter lock 20 are in the Figures 5 and 6 shown.
- the counter-lock 20 is placed on a tubular ground sleeve 21, partially embedded in it and firmly connected to it.
- the Figures 5 and 6 show a perspective top view or a perspective partial section bottom view of a counter-lock 20 of the post system.
- the counter-lock 20 is essentially hat-shaped and has a support plate 203 on the top and a circumferential side wall 2014 adjoining this, which extends downward from the circumference of the support plate 203.
- the support plate 203 is essentially a circular disk and the side wall is a tubular sleeve.
- central recess 202 which extends along the longitudinal center axis of the counter lock 20 through the support plate 203 and forms a passage from the inside of the counter lock to the outside.
- the central recess 202 has a central bore 2020, the diameter of which is matched to that of the shaft 1210 of the guide mandrel 121 in such a way that that the guide pin 121 can be guided in the central recess 202 so that it can be easily displaced.
- From the central bore 2020 three radial recesses 2021 extend radially outward.
- the radial recesses 2021 are rotationally symmetrical and evenly distributed around the central bore 2020.
- the dimensions of the radial recesses 2021 are coordinated with the elevations 1212 of the guide mandrel 121 in such a way that the elevations 1212 can easily be guided in the radial recesses 2021.
- peripheral recesses 201 are arranged around the central recess 202 at a distance from it.
- the peripheral recesses 201 are arranged rotationally symmetrically and uniformly around the central recess 202, ie at an angle of 120 degrees to one another.
- each peripheral recess 201 In a cross-section parallel to the support plate 203, each peripheral recess 201 essentially has the shape of a ring segment, with each peripheral recess 201 being divided into an insertion area 2010 and a closure area 2011.
- Each peripheral recess 201 extends on the circumference over an angular area, which is in half the introduction area 2010 and the closure area 2011 is divided.
- the cross section of the insertion area 2010 is coordinated with the cross section of the elevation 1220 of the claw 122 of the closure 12 in such a way that it can be easily introduced into the insertion area 2010.

Description
Die vorliegende Erfindung betrifft ein Pfostensystem für die Befestigung von Pfosten an einem Untergrund. Wobei unter Pfosten auch Stangen, Ständer oder dergleichen zu verstehen sind. Beispielsweise handelt es sich dabei um Absperrpfosten, Poller, Geländer, Absturzsicherungen, Wegweiser, Halterungen für Schilder oder Abfalleimer, oder Fahrradständer. Der Untergrund kann beispielsweise eine Fahrbahn, ein Gehweg oder ein Platz sein, im Freien oder im Innern eines Gebäudes.The present invention relates to a post system for fastening posts to a substrate. Whereby posts are also to be understood as rods, stands or the like. For example, these are barrier posts, bollards, railings, fall protection, signposts, brackets for signs or rubbish bins, or bike racks. The underground can be, for example, a roadway, a sidewalk or a square, outdoors or inside a building.
Aus der
Es ist daher eine Aufgabe der Erfindung, ein Pfostensystem und eine Bodenverankerung zur Verfügung zu stellen, welche die oben-genannten Nachteile vermeidet.It is therefore an object of the invention to provide a post system and a floor anchorage which avoids the above-mentioned disadvantages.
Eine solche Aufgabe löst ein Pfostensystem mit den Merkmalen des Anspruchs 1 und eine Bodenverankerung mit den Merkmalen des Anspruchs 10.Such a problem is achieved by a post system with the features of
Bei einem bevorzugten Pfostensystem mit einem Pfosten und einer Bodenverankerung ist der Pfosten in der Bodenverankerung lösbar angeordnet, wobei der Pfosten mittels eines unterseitig an diesem befindlichen Verschlusses auf einem oberseitig an der Bodenverankerung befindlichen dieser zugeordneter Gegenverschlusses verdrehbar angeordnet ist. Pfosten und Bodenverankerung können aus Metall sein, wie beispielsweise Stahl, rostfreiem Stahl, Aluminium oder dergleichen, oder aus Kunststoff oder Verbundwerkstoff, oder aus einer Kombination davon. Im Pfosten kann oben ein Schloss und unten ein mit diesem durch ein Zugelement in Wirkverbindung stehender Bolzen vorgesehen sein, welcher in Schliessstellung den Verschluss durchdringend, in eine Bolzenaufnahmeausnehmung in der Bodenverankerung eingreift. Der Verschluss ist durch eine Steck-Dreh-Verbindung, wie beispielsweise ein Bajonettverschluss oder eine Storz-Kupplung, mit dem Gegenverschluss lösbar verbunden. Der Verschluss des Pfostens weist unterseitig im Weiteren einen zentrisch angeordneten Führungsdorn mit einem zentrischen Schaft auf und die Bodenverankerung weist oberseitig im Weiteren eine zentrische Ausnehmung mit einer zum zentrischen Schaft komplementären zentrischen Bohrung auf.In a preferred post system with a post and a floor anchor, the post is detachably arranged in the floor anchor, the post being rotatably arranged by means of a lock located on the underside of this on a counter lock assigned to the upper side of the floor anchor. The posts and ground anchors can be metal, such as steel, stainless steel, aluminum, or the like, or plastic or composite, or a combination thereof. In the post, a lock can be provided at the top and a bolt that is in operative connection therewith by a tension element, which in the closed position penetrates the lock and engages in a bolt receiving recess in the ground anchorage. The lock is releasably connected to the counter lock by a plug-and-turn connection, such as a bayonet lock or a Storz coupling. The closure of the post also has a centrally arranged guide pin with a central shaft on the underside, and the floor anchorage also has a central recess on the upper side with a central bore complementary to the central shaft.
Erfindungsgemäss weist der Führungsdorn mindestens eine seitlich vom Schaft nach aussen abstehende Erhebung auf und die zentrische Ausnehmung weist mindestens eine zur Erhebung komplementäre radiale Ausnehmung auf, welche sich seitlich der zentrischen Bohrung nach aussen erstreckt. Dies hat den Vorteil, dass der Pfosten beim Einführen des Führungsdorns in die Bodenverankerung nicht nur zentriert sondern auch ausgerichtet wird. Dadurch muss der Pfosten nicht mehr so lange gedreht werden bis irgendwann einmal die Verschlusselemente des Pfostens in die dafür vorgesehenen Ausnehmungen in der Bodenverankerung finden.According to the invention, the guide mandrel has at least one outwardly to the side of the shaft protruding elevation and the central recess has at least one radial recess which is complementary to the elevation and which extends outwardly to the side of the central bore. This has the advantage that the post is not only centered but also aligned when the guide pin is inserted into the ground anchorage. As a result, the post no longer has to be rotated until at some point the locking elements of the post find their way into the recesses provided in the ground anchorage.
Hierfür ist es vorteilhaft, wenn der Führungsdorn länger als die Verschlusselemente ausgebildet ist und diesen in der Einführungsrichtung vorsteht. Ebenfalls vorteilhaft ist die Ausgestaltung von sanften Übergängen zwischen dem zentrischen Schaft des Führungsdorns und den an diesem vorgesehenen Erhebungen, sowie zwischen der zentrischen Bohrung des Gegenverschlusses und den an diese anschliessende radialen Ausnehmungen, da dann die Ausrichtung unter geringem Kraftaufwand, fast schon wie von alleine geschieht.For this purpose, it is advantageous if the guide pin is made longer than the closure elements and this protrudes in the insertion direction. The design of smooth transitions between the central shaft of the guide mandrel and the elevations provided on it, as well as between the central bore of the counter-lock and the radial recesses adjoining this, is also advantageous, since the alignment then takes place almost automatically with little effort .
Vorzugsweise weist der Führungsdorn eine Spitze auf, welche durch ein konisches zusammenlaufen des Umfangs des Schaftes realisiert ist. Im Bereich der Spitze ist keine Erhebung vorhanden. Anschliessend an die Spitze schliesst ein Bereich mit der mindestens einen Erhebung an. Alternativ können zwei, drei, vier oder mehr Erhebungen vorhanden sein. Vorzugsweise entspricht die Anzahl der Erhebungen des Führungsdorns der Anzahl der radialen Ausnehmungen im Gegenverschluss. Eine ungleiche Anzahl ist jedoch auch denkbar. Anschliessend an den Bereich mit der mindestens einen Erhebung schliesst ein Schaftbereich an, welcher keine Erhebungen aufweist. Dieser Bereich ermöglicht es, dass der Führungsdorn, und somit der ganze Verschluss, nach dem Einführen in den Gegenverschluss drehbar ist. Hierfür ist es vorteilhaft, wenn der Gegenverschluss einen oberseitigen Bereich mit den für den Führungsdorn komplementären Ausnehmungen aufweist, und einen darunterliegenden Bereich, der derart ausgebildet ist, dass er den Führungsdorn mit dessen Erhebungen nicht an einer Drehung um seine Längsachse behindert.The guide mandrel preferably has a tip which is implemented by conically converging the circumference of the shaft. There is no elevation in the area of the tip. An area with the at least one elevation adjoins the top. Alternatively, there can be two, three, four or more elevations. The number of elevations on the guide pin preferably corresponds to the number of radial recesses in the counter lock. However, an unequal number is also conceivable. The area with the at least one elevation is followed by a shaft area which has no elevations. This area enables the guide pin, and thus the entire closure, to be rotatable after being inserted into the counter-closure. For this purpose, it is advantageous if the counter-lock has an upper-side area with the recesses complementary to the guide pin, and an underlying area which is designed in such a way that it does not prevent the guide pin with its elevations from rotating about its longitudinal axis.
In einer vorteilhaften Ausführungsform ist die mindestens eine radiale Ausnehmung derart ausgebildet, dass sie beim Einführen des Führungsdorns in die zentrische Ausnehmung als Führung für die mindestens eine Erhebung dient und nach dem Herstellen der Steck-Dreh-Verbindung als Bolzenaufnahmeausnehmung dient. D.h. nach der Drehung in die Verschlussposition rastet der Bolzen in eine der mindestens einen radialen Ausnehmungen ein. Hierfür ist es vorteilhaft, wenn die Längsmittelachse des Bolzens auf einen Kreis um die Längsmittelachse des Führungsdorns liegt, welcher innerhalb dem Bereich der radialen Ausnehmungen liegt. Diese Ausführungsform hat den Vorteil, dass keine zusätzlichen Ausnehmungen für die Aufnahme des Bozens im Gegenverschluss vorgesehen werden müssen.In an advantageous embodiment, the at least one radial recess is designed in such a way that, when the guide pin is inserted into the central recess, it acts as a Guide for the at least one elevation is used and serves as a bolt receiving recess after the plug-in-turn connection has been established. That is, after the rotation into the closed position, the bolt engages in one of the at least one radial recesses. For this purpose, it is advantageous if the longitudinal center axis of the bolt lies on a circle around the longitudinal center axis of the guide mandrel which lies within the area of the radial recesses. This embodiment has the advantage that no additional recesses have to be provided for receiving the bolt in the counter lock.
Alternativ und mit dem gleichen Gedanken, kann der Bolzen derart angeordnet sein, dass seine Längsmittelachse auf einem Kreis um die Längsmittelachse des Führungsdorns liegt, welcher innerhalb dem Bereich von peripheren Ausnehmungen liegt, welche zur Aufnahme von Verschlusselementen vorgesehen sind. Vorzugsweise befindet sich der Bolzen im verschlossenen Zustand des Pfostens in einem Einführbereich der peripheren Ausnehmungen, da dieser nur während der Einführung der Verschlusselemente des Pfostens in den Gegenverschluss durch die Verschlusselemente belegt ist und im verschlossenen Zustand unbelegt ist. Die Anordnung des Bolzens in einem peripheren Bereich hat den Vorteil, dass grössere Drehmomente aufgenommen werden können, welche auf den Pfosten um seine Längsmittelachse, bzw. die des Führungsdorns wirken.Alternatively and with the same idea, the bolt can be arranged in such a way that its longitudinal center axis lies on a circle around the longitudinal center axis of the guide mandrel, which lies within the area of peripheral recesses which are provided for receiving closure elements. In the locked state of the post, the bolt is preferably located in an insertion area of the peripheral recesses, since this is only occupied by the locking elements during the insertion of the locking elements of the post into the counter-lock and is unoccupied in the locked state. The arrangement of the bolt in a peripheral area has the advantage that larger torques can be absorbed, which act on the post about its longitudinal center axis or that of the guide pin.
Bevorzugt ist in der Bodenverankerung ein verschiebbarer Verschlusskern angeordnet, welcher in einem mit dem Pfosten unverbundenen Zustand die an der Bodenverankerung oberseitig befindlichen Ausnehmungen nach oben hin verschliesst und welcher durch den Führungsdorn und/oder weitere Elemente der Steck-Dreh-Verbindung niederdrückbar ist. Durch das Verschliessen der oberseitigen Ausnehmungen wird verhindert, dass die Bodenverankerung verstopft wird. Beispielsweise wird verhindert, dass Laub, Schnee oder Eis die Ausnehmungen verstopft und so die Einführung des Pfostens erschwert. Der Verschlusskern kann aus Metall oder aus Kunststoff gefertigt sein. Ein Verschlusskern aus Metall, ist besonders verschleissfest, wodurch eine lange Lebensdauer erreicht werden kann. Beispielsweise ist ein metallener Verschlusskern aus rostfreiem Stahl oder Aluminium gefertigt. Ein Verschlusskern aus Kunststoff hat den Vorteil, dass der Kunststoff einen anderen Wärmeausdehnungskoeffizient als das ihn umgebende Gehäuse des Gegenverschlusses aufweist. Dies verhindert oder reduziert die Gefahr von Vereisung bei Temperaturen um oder unter dem Gefrierpunkt. Beispielsweise basiert ein solcher Verschlusskern auf einer Polykarbonat-Mischung. Vorteilhafter Weise wird der Verschlusskern durch ein Federelement in die oberseitig befindlichen Ausnehmungen nach oben gedrückt. Beispielsweise durch eine Spiral- oder Blattfeder oder andere aus dem Stand der Technik bekannte Federelemente.A displaceable locking core is preferably arranged in the floor anchorage, which, when not connected to the post, closes the recesses on the upper side of the floor anchorage and which can be pressed down by the guide pin and / or other elements of the plug-and-turn connection. Closing the recesses on the top prevents the floor anchoring from becoming clogged. For example, leaves, snow or ice are prevented from clogging the recesses and thus making it more difficult to insert the post. The locking core can be made of metal or plastic. A metal locking core is particularly wear-resistant, which means that a long service life can be achieved. For example, a metal locking core is made of stainless steel or aluminum. A closure core made of plastic has the advantage that the plastic has a different coefficient of thermal expansion than the housing of the mating closure that surrounds it. This prevents or reduces the risk of icing at temperatures around or below freezing point. For example, such a closure core is based on a polycarbonate mixture. The closure core is advantageously pressed upwards into the recesses located on the top by a spring element. For example, by a spiral or leaf spring or other spring elements known from the prior art.
In einer bevorzugten Ausführung kann der Verschluss einen zentrisch angeordneten Führungsdorn und vorzugsweise mindestens eine seitlich vom Schaft nach aussen abstehende Erhebung aufweisen. Die zu erzielenden Vorteile sind gleich wie beim oben-beschriebenen Pfostensystem.In a preferred embodiment, the closure can have a centrally arranged guide pin and preferably at least one elevation protruding laterally outward from the shaft. The advantages to be achieved are the same as with the post system described above.
Bevorzugt weist der Verschluss mindestens eine Kralle als Element der Steck-Dreh-Verbindung auf. Es können auch andere bekannte Verschlusselemente wie für Bajonettverschlüsse oder Storz-Kupplungen, wie beispielsweise eine Kombination von Schlitz und Bolzen, verwendet werden.The closure preferably has at least one claw as an element of the plug-and-turn connection. Other known locking elements, such as for bayonet locks or Storz couplings, such as a combination of slot and bolt, can also be used.
In einer vorteilhaften Ausführungsform weist der Führungsdorn in seinem Innern eine Seilaufnahme in der Form einer Bohrung auf, welche sich von der dem Führungsdorn gegenüberliegenden Seite des Verschlusses entlang der Längsachse des Führungsdorns in diesen hinein erstreckt, wobei am Führungsdorn Aufnahmen für Elemente zur Befestigung eines Rückhalteseils in der Seilaufnahme vorgesehen sind. Das Rückhalteseil hat den Vorteil, dass wenn der Verschluss vom Rest des Pfostens getrennt wird, der Verschluss dennoch mit dem Rest des Pfostens verbunden bleibt, sodass, wenn der Verschluss noch im Gegenverschluss verriegelt ist, sich der Rest des Pfostens nicht beliebig vom Gegenverschluss, bzw. der Bodenverankerung entfernen kann.In an advantageous embodiment, the guide mandrel has a cable receptacle in its interior in the form of a bore, which extends from the side of the closure opposite the guide mandrel along the longitudinal axis of the guide mandrel into the latter, with receptacles on the guide mandrel for elements for attaching a restraint rope in the rope holder are provided. The restraint rope has the advantage that if the lock is separated from the rest of the post, the lock still remains connected to the rest of the post, so that if the lock is still locked in the mating lock, the rest of the post does not move freely from the mating lock or . can remove the floor anchor.
Um zu verhindern, dass der Verschluss aus dem Gegenverschluss gelöst werden kann, wenn der Rest des Pfostens vom Verschluss abgetrennt wurde, ist vorzugsweise ein Sperrbolzen im Verschluss vorgesehen, der mit dem Gegenverschluss verriegelt, wenn der Verschluss vom Rest des Pfostens, d.h. vom Boden des Pfostens getrennt wird.In order to prevent the closure from being released from the counter-closure when the rest of the post has been separated from the closure, a locking pin is preferably provided in the closure, which locks with the counter-closure when the closure from the rest of the post, ie from the bottom of the The post is separated.
Wie der Verschluss, lässt sich auch die erfindungsgemässe Bodenverankerung mit aus dem Stand der Technik bekannten Pfosten, Stangen, Ständer oder dergleichen, insbesondere Absperrpfosten einsetzen, wobei eine solche Bodenverankerung ein oberseitig an dieser befindlicher Gegenverschluss eine zentrisch angeordnete Ausnehmung mit einer zentrischen Bohrung aufweist, wobei die zentrische Ausnehmung mindestens eine radiale Ausnehmung aufweist, welche sich seitlich der zentrischen Bohrung nach aussen erstreckt. Die zu erzielenden Vorteile sind gleich wie beim oben-beschriebenen Pfostensystem.Like the lock, the floor anchorage according to the invention can also be made with posts, rods, stands or the like known from the prior art, in particular Use barrier posts, such a ground anchorage having a counter-lock located on the top of this having a centrally arranged recess with a central bore, the central recess having at least one radial recess which extends outwardly to the side of the central bore. The advantages to be achieved are the same as with the post system described above.
Vorzugsweise weist die Bodenverankerung oberseitig im Weiteren mindestens eine periphere Ausnehmung als Element der Steck-Dreh-Verbindung auf, welche einen Einführbereich und einen Verschlussbereich aufweist, wobei der Einführbereich in radialer Richtung breiter als der Verschlussbereich ausgestaltet ist.The floor anchorage preferably also has at least one peripheral recess on the upper side as an element of the plug-and-turn connection, which has an insertion area and a closure area, the insertion area being wider than the closure area in the radial direction.
Wie schon vorgängig im Zusammenhang mit dem Pfostensystem beschrieben, ist in der alleinstehenden Bodenverankerung ein verschiebbarer Verschlusskern angeordnet, durch welchen die an der Bodenverankerung oberseitig befindlichen Ausnehmungen nach oben hin verschliessbar sind und welcher durch ein Federelement in einer die Ausnehmungen verschliessende Position gehalten ist.As already described above in connection with the post system, a displaceable locking core is arranged in the stand-alone floor anchorage, through which the recesses located on the top of the floor anchorage can be closed upwards and which is held in a position closing the recesses by a spring element.
Ein Pfostensystem kann zur unterseitigen Befestigung des Verschlusses an einem Boden des Pfostens mindestens ein Befestigungselement, eine erste Aufnahme am Verschluss und eine zweite Aufnahme am Boden aufweisen, wobei jedes Befestigungselement an seiner einen Seite in der ersten Aufnahme aufgenommen ist und an seiner anderen Seite in der zweiten Aufnahme aufgenommen ist. Das Befestigungselement weist eine Längsachse auf und der Verschluss und der Boden sind in der Richtung der Längsachse gegeneinander verspannt. Vorzugsweise ist die zweite Aufnahme im Wesentlichen in der Richtung der Längsachse in einem vorbestimmten Bereich bewegbar. Dies führt zu einer bedingten Nachgiebigkeit der zweiten Aufnahme, was den Vorteil hat, dass die auf das oder die Befestigungselemente wirkenden Kräfte gedämpft werden und somit eine Beschädigung der Befestigungselemente reduziert werden kann.A post system can have at least one fastening element, a first receptacle on the closure and a second receptacle on the bottom for fastening the closure to the bottom of the post, each fastening element being received on one side in the first receptacle and on its other side in the second recording is recorded. The fastening element has a longitudinal axis and the closure and the base are braced against one another in the direction of the longitudinal axis. The second receptacle is preferably movable essentially in the direction of the longitudinal axis in a predetermined range. This leads to a limited resilience of the second receptacle, which has the advantage that the forces acting on the fastening element or elements are dampened and thus damage to the fastening elements can be reduced.
Bevorzugt weist der Boden einen Durchgang für jedes Befestigungselement auf und die zweite Aufnahme weist mindestens ein Führungselement auf, welches um jeden Durchgang angeordnet ist, wobei mindestens eine Fixierung und mindestens ein Federelement für das entsprechende Befestigungselement in jedem Führungselement geführt sind. Als Führungselemente eignen sich beispielsweise Käfige oder Hülsen, als Fixierung beispielsweise Schraubenmuttern, Splinte oder Bolzen und als Federelement beispielsweise Zug-, Druck- oder Tellerfedern.The base preferably has a passage for each fastening element and the second receptacle has at least one guide element which is arranged around each passage, with at least one fixation and at least one spring element for the corresponding fastening element in each guide element are led. Cages or sleeves, for example, are suitable as guide elements, nuts, split pins or bolts, for example, as fixings, and tension, compression or disc springs, for example, as spring elements.
Vorzugsweise ist das mindestens eine Federelement zwischen dem Boden und der mindestens einen Fixierung angeordnet. Bei einer solchen Anordnung wird die Fixierung durch das Federelement vom Boden weggedruckt und es erfolgt eine Zunahme der auf die Fixierung wirkende Kraft, wenn die Fixierung in die Richtung des Boden verschoben wird.The at least one spring element is preferably arranged between the floor and the at least one fixation. With such an arrangement, the fixation is pushed away from the floor by the spring element and there is an increase in the force acting on the fixation when the fixation is shifted in the direction of the floor.
In einer bevorzugten Ausführungsform wird das oben genannte Befestigungselement als eine Sollbruchschraube zur Befestigung des Verschlusses an einem Boden des Pfostens ausgestaltet, welche einen Gewindeschaft mit einem Aussengewinde und einem Kopf mit einem Mitnahmeprofil aufweist, wobei die Sollbruchschraube einen Sollbruchstellenbereich am Gewindeschaft aufweist, wobei auf der dem Kopf gegenüberliegenden Seite des Sollbruchstellenbereichs, anschliessend an diesen mindestens eine Ausnehmung ausgebildet ist. Die Sollbruchschraube soll verhindern, dass bei einer Überschreitung einer zulässigen Kraft auf den Verschluss, dieser beschädigt wird. Der Sollbruchstellenbereich stellt sicher, dass die Sollbruchschraube bricht, bevor der Verschluss beschädigt wird. Nachdem der Kopf der Schraube vom Gewindeschaft abgetrennt wurde, ist es wichtig, dass der Gewindeschaft dennoch entfernt werden kann. Hierfür ist am Gewindeschaft die mindestens eine Ausnehmung vorgesehen.In a preferred embodiment, the above-mentioned fastening element is designed as a predetermined breaking screw for fastening the closure to a bottom of the post, which has a threaded shaft with an external thread and a head with a driving profile, the predetermined breaking screw having a predetermined breaking point area on the threaded shaft, with the Head opposite side of the predetermined breaking point area, adjoining this at least one recess is formed. The predetermined breaking screw is intended to prevent the closure from being damaged if a permissible force is exceeded. The predetermined breaking point area ensures that the predetermined breaking screw breaks before the closure is damaged. After the head of the screw has been separated from the threaded shaft, it is important that the threaded shaft can still be removed. For this purpose, the at least one recess is provided on the threaded shaft.
Vorzugsweise ist der Sollbruchstellenbereich anschliessend an den Kopf ausgebildet. Diese Anordnung stellt sicher, dass die Ausnehmung nach dem Abtrennen des Kopfes von der Richtung her zugänglich ist, in welcher sich zuvor der Kopf befunden hat. Mit einem Werkzeug kann in diese Ausnehmung eingegriffen werden, um den Gewindeschaft zu entfernen. Anstelle einer Ausnehmung können zwei, drei, vier, fünf, sechs oder mehr Ausnehmungen vorgesehen sein. So können beispielsweise sechs Ausnehmungen derart ausgebildet sein, dass ein herkömmlicher Sechskant verwendet werden kann, um den Gewindeschaft herauszudrehen. Alternativ kann eine Vielzahl von Ausnehmungen vorgesehen sein, welche beispielsweise als Torx ausgebildet sein.The predetermined breaking point area is preferably formed adjacent to the head. This arrangement ensures that, after the head has been separated, the recess is accessible from the direction in which the head was previously located. A tool can be used to reach into this recess in order to remove the threaded shaft. Instead of one recess, two, three, four, five, six or more recesses can be provided. For example, six recesses can be designed in such a way that a conventional hexagon can be used to unscrew the threaded shaft. Alternatively, a plurality of recesses can be provided, which are designed as Torx, for example.
In einer alternativen Ausführungsform ist die mindestens eine Ausnehmung derart ausgebildet, dass sie den Gewindeschaft quer zu seiner Längsmittelachse durchdringt. Wird dann der Kopf abgetrennt, so entsteht ein Schlitz, welcher sich quer durch den Gewindeschaft erstreckt. Als Werkzeug kann dann ein herkömmlicher Schlitzschraubendreher verwendet werden.In an alternative embodiment, the at least one recess is of this type designed that it penetrates the threaded shaft transversely to its longitudinal center axis. If the head is then separated, a slot is created which extends transversely through the threaded shaft. A conventional slotted screwdriver can then be used as a tool.

Zwischen dem Deckel 13 und dem oberen Ende des Pfostens 1, kann optional ein Zwischenstück 14 angeordnet werden. Das Zwischenstück 14 ist ein ringförmiges Bauteil und schliesst an seinem einen Ende im Wesentlichen nahtlos an das Rohr 10 des Pfostens 1 an und hat an seinem anderen Ende eine Aufnahme für den Deckel 13 ausgebildet. Im Zwischenstück 14 sind Ausnehmungen 140 vorgesehen. Diese Ausnehmungen 140 können genutzt werden, um beispielsweise eine Kette darin aufzunehmen, was den Vorteil hat, dass keine Ösen am Pfosten benötigt werden. Die Bauweise mit den Ausnehmungen 14 ist kostengünstiger als jene mit am Rohr des Pfostens befestigten Ösen. Ausserdem kann ein solcher Deckel 13 auch ohne Ketten eingesetzt werden, ohne dass Ösen störend auf der Pfostenseite von dieser ab- und überstehen.An
Im Posteninnern ist in einem oberen Bereich ein Schloss 8 angeordnet, welches von aussen bedienbar ist und in welches ein Schlüssel 80 zur Betätigung einführbar ist. Das Schloss 80 ist über eine Verschlussstange 70 mit einem Verschlussbolzen 7 wirkverbunden. Ebenfalls im Pfosteninnern sind die zweiten Aufnahmen 30 zur Aufnahme der Befestigungselemente 4 des Verschlusses 12, wie sie in der
Die
Der Führungsdorn121 wird im verschlossenen Zustand in der Bodenverankerung 2 durch eine zentrische Bohrung 2020 einer zentrischen Ausnehmung 202 geführt. Als Verdrehsicherung ist der Verschlussbolzen 7 in einem Verschlussbolzendurchgang 110 im Boden 11 und in einem dazu kollinearen Durchgang 127 im Verschluss 12 geführt und greift im Gegenverschluss 20 in eine radiale Ausnehmung 2021 der Zentrischen Ausnehmung 202. Um den Eingriff zu lösen, muss der Schlüssel 80 im Schloss 8 betätigt werden, wodurch der Verschlussbolzen 7 mittels der Verschlussstange 70 aus der radialen Ausnehmung 2021 gezogen wird. Alternativ kann der Verschlussbolzen 7 derart angeordnet sein, dass er in eine der peripheren Ausnehmungen 201 eingreifen kann. Ist der Verschlussbolzen 7 im Radius weiter weg vom Zentrum angeordnet, so können mit dem gleichen Bolzen die grösseren Drehmomente aufgenommen werden, oder es kann ein kleinerer Bolzen verwendet werden, um das gleiche Drehmoment aufzunehmen.In the closed state, the
Der Absperrpfosten 1 weist in seinem unteren Bereich einen Boden 11 auf, welcher in das Rohr 10 eingelassen und mit diesem fest verbunden ist. Unterhalb des Bodens 11 und an diesen fluchtend anschliessend ist der Verschluss 12 angeordnet. Der Verschluss 12 ist mittels einer Befestigung 3 am Boden 11 fest montiert, wobei die Befestigung 3 eine erste Aufnahme 123 am Verschluss 12, eine zweite Aufnahme 30 am Boden 11 und eine Sollbruchschraube 4 aufweist. Einzelheiten des Verschlusses 12 sind in den
Im Innern des Pfostens 1, d.h. im Innern des Rohres 10 ist die zweite Aufnahme 30 am Boden 11 angeordnet. Die zweite Aufnahme 30 weist Führungselemente 31 in der Form von Gewindebolzen auf. Drei solcher Gewindebolzen 31 sind um jeweils eine Durchgangsbohrung 111 einer Sollbruchschraube 4 angeordnet. Zwischen den drei Gewindebolzen 31 ist ein Stapel von Tellerfedern 35 angeordnet, welcher seitlich durch die Gewindebolzen 31 geführt ist. Auf dem Tellerfederstapel 35 ist eine Schraubenmutter 34 angeordnet, welche als Fixierung 34 der Sollbruchaschraube 4 dient. Über der Schraubenmutter 34 ist eine Anschlagplatte 32 vorgesehen, welche die Mutter 34 nach oben abstützt und gleichzeitig als Verdrehsicherung für die Mutter 34 dient. Die Anschlagplatte 32 ist durch Muttern 33 gesichert, welche an den freien Enden der Gewindebolzen 31 festgeschraubt werden. Eine Sollbruchschraube 4 kann durch die erste Aufnahme 123 im Verschluss 12 eingeführt, durch den Durchgang 111 im Boden 11 gestossen werden, bis sie die Mutter 34 erreicht, wo sie eingeschraubt werden kann. Je mehr die Schraube 4 angezogen wird, desto mehr werden die Tellerfedern 35 zusammengedrückt und desto grösser wird die Klemmkraft. Die Schraube 4 wird nicht vollständig angezogen, sodass ein Abheben des Bodens 11 von bis zu 15 Millimeter, vorzugsweise bis zu 10 Millimeter, vorzugsweise bis zu 8 Millimeter bezüglich des Verschlusses 12 möglich ist. Vergrössert sich die Distanz zwischen Boden 11 und Verschluss 12, so nimmt die Klemmkraft zu, bis alle Tellerfedern vollständig zusammengedrückt sind. Wird die diese Distanz weiter erhöht, so erhöht sich die auf die Sollbruchschraube 4 wirkende Längskraft. Wenn die Kraft den zugelassenen Wert der Sollbruchschraube übersteigt, so bricht diese im Sollbruchstellenbereich 44 und der Schraubenkopf 42 wird vom Gewindeschaft 40 getrennt. Die drei zweiten Aufnahmen 30 sind regelmässig, d.h. unter einem Winkel von 120 Grad zueinander bezüglich der Mittelachse des Bodens 11 um diese angeordnet.In the interior of the

Von der Oberseite der Scheibe 120 ist eine Seilaufnahme 126 in der Form einer Bohrung angeordnet, welche sich von der Oberseite auf der Mittelachse der Scheibe 120 in den Führungsdorn 121 hinein erstreckt. Seitlich am Schaft 1210 sind Gewindebohrungen 124 vorgesehen, in welche Schraubenelemente zur Klemmung eines Drahtseils eingeschraubt werden können.Arranged from the top of the
In einem peripheren, umfangnahen Bereich der Scheibe 120 erstrecken sich drei rotationssymmetrisch verteilte Klauen 122 von der Scheibe 120 nach unten. Jede Klaue 122 ist eine sich von der Scheibe 120 parallel zur deren Rotationsachse erstreckende Erhebung 1220 und hat in einem zur Scheibe 120 parallelen Querschnitt im Wesentlichen die Form eines Ringsegments. Die radiale Abmessung jedes Ringsegments beträgt 5 bis 15 Millimeter, vorzugsweise 5 bis 10 Millimeter. Die radiale Abmessung im Bereich der Erhebungen 1220 ist im Wesentlichen doppelt so gross, wie die der Ringsegmente, d.h. 5 bis 30 Millimeter, vorzugsweise 10 bis 20 Millimeter. Ein freies Ende der Kralle ist gegen das freie Ende hin in Umfangrichtung zusammenlaufend. D.h. Das freie Ende weist beidseitig in Umfangrichtung Fasen 1223 auf. In einem der Scheibe 120 anschliessenden Bereich weist die Kralle auf der im Radius nach aussen gerichteten Seit eine Ausnehmung 1221 auf, sodass die Kralle in diesem Bereich in Radiusrichtung dünner ausgebildet ist. Eine gegen die Scheibe 120 gerichtet Fläche der Ausnehmung 1221 ist parallel zur Scheibe 120 ausgebildet und eine dieser Fläche gegenüberliegende Verschlussfläche 1222 der Ausnehmung 1221 ist schraubenförmig ausgebildet. Die Schraubenform bewirkt, dass sich die Verschlussfläche 1222 des Pfostens beim Anziehen des Pfostens, d.h. beim Verdrehen des Pfostens, gegen eine entsprechende Verschlussfläche 2013 des Gegenverschlusses 20 verspannt. Alternativ kann auch die Verschlussfläche 1222 parallel zur Scheibe 120 ausgebildet sein. Solange mindestens eine der Verschlussflächen 1222, 2013 schraubenförmig ausgebildet ist, findet beim Anziehen des Pfostens eine Verspannung statt.In a peripheral region of the
In der Scheibe 120 sind drei rotationssymmetrisch verteilet Senkbohrungen 123 ausgebildet, wobei die Senkungen auf der Unterseite, d.h. auf der Seite des Führungsdorns 121 ausgebildet sind. Im Weiteren sind in der Scheibe 120 eine Durchgangsbohrung 127 und eine Sperrbolzenaufnahme 125 angeordnet, deren Längsmittelachsen sich auf einem gemeinsamen Kreis um den Scheibenmittelpunkt befinden. Die Durchgansbohrung 127 weist einen Durchmesser auf, der so mit dem Durchmesser des Verschlussbolzens 7 abgestimmt ist, dass dieser leicht in der Durchgangsbohrung 127 geführt werden kann. Die Sperrbolzenaufnahme 125 weist von der Scheibenoberseite her gesehen einen grösseren Durchmesser auf, als auf der gegenüberliegenden Seite. Der so entstehende Absatz bildet einen unteren Anschlag für einen Sperrbolzen 90 wie er in der

In der Mitte der Auflageplatte 203 ist eine zentrische Ausnehmung 202 angeordnet, welche sich entlang der Längsmittelachse des Gegenverschlusses 20 durch die Auflageplatte 203 hindurch erstreckt und einen Durchgang vom Inneren des Gegenverschlusses nach aussen bildet. Die zentrische Ausnehmung 202 weist eine zentrische Bohrung 2020 auf, deren Durchmesser mit dem des Schaftes 1210 des Führungsdorns 121 derart abgestimmt ist, dass der Führungsdorn 121 leicht versschiebbar in der zentrischen Ausnehmung 202 führbar ist. Von der zentrischen Bohrung 2020 erstrecken sich drei radiale Ausnehmungen 2021 radial nach aussen. Die radialen Ausnehmungen 2021 sind rotationssymmetrisch und gleichverteilt um die zentrische Bohrung 2020 angeordnet. Die Abmessungen der radialen Ausnehmungen 2021 sind mit den Erhebungen 1212 des Führungsdorns 121 derart abgestimmt, dass die Erhebungen 1212 leicht in den radialen Ausnehmungen 2021 führbar sind.In the middle of the
In der Auflageplatte 203 sind um die zentrische Ausnehmung 202, beabstandet zu dieser periphere Ausnehmungen 201 angeordnet. Die peripheren Ausnehmungen 201 sind rotationssymmetrisch und gleichmässig um die zentrische Ausnehmung 202 angeordnet, d.h. in einem Winkel von 120 Grad zueinander. In einem zur Auflageplatte 203 parallelen Querschnitt hat jede periphere Ausnehmung 201 im Wesentlichen die Form eines Ringsegments, wobei jede periphere Ausnehmung 201 in einen Einführbereich 2010 und in einen Verschlussbereich 2011 aufgeteilt ist Jede periphere Ausnehmung 201 erstreckt sich am Umfang über einen Winkelbereich, der hälftig in den Einführungsbereich 2010 und den Verschlussbereich 2011 aufgeteilt ist. Der Querschnitt des Einführungsbereichs 2010 ist derart mit dem Querschnitt der Erhebung 1220 der Klaue 122 des Verschlusses 12 abgestimmt, dass dieser leicht in den Einführungsbereich 2010 einführbar ist. Der Querschnitt des Verschlussbereichs 2011 ist derart mit dem Querschnitt im Bereich der Ausnehmung 1221 der Klaue 122 des Verschlusses 12 abgestimmt, dass der Verschluss 12 vom Einführbereich 2010 leicht drehbar in den Verschlussbereich 2011 führbar ist. Der Innenradius des Einführungsbereichs 2010 entspricht dem Innenradius des Verschlussbereichs 2011. Der Aussenradius des Verschlussbereichs 2011 ist kleiner als der Aussenradius des Einführungsbereichs 2010, wodurch in Radiusrichtung ein Absatz zwischen den beiden Bereichen entsteht. Der Absatz erstreckt sich jedoch nicht über die gesamte Höhe des Gegenverschlusses 20. Im Verschlussbereich 2011 ist eine Ausnehmung 2012 vorhanden, welche im Querschnitt die gleichen Abmessungen wie die des Absatzes aufweist und welche bewirkt, dass der Aussendurchmesser im Bereich der Ausnehmung, dem Aussendurchmesser des Einführungsbereichs 2010 entspricht. Durch die Ausnehmung 2012 entsteht eine Verschlussfläche 2013, welche zur Auflagefläche 203 beabstandet und dieser gegenüberliegend angeordnet ist. Die Verschlussfläche 2013 ist schraubenförmig ausgebildet. Alternativ kann die Verschlussfläche 2013 parallel zur Auflagefläche 203 ausgebildet sein. Die Verschlussfläche 2013 des Gegenverschlusses 20 ist komplementär zur Verschlussfläche 1222 des Verschlusses 12 ausgebildet.In the
Wie in der
Ein Rohr 23 ist ebenfalls auf der Innenseite der Auflageplatte 203 des Gegenverschlusses 20 angeordnet. Das Rohr 23 ist konzentrisch um die Längsmittelachse des Gegenverschlusses 20 angeordnet und somit auch um die zentrische Ausnehmung 202 des Gegenverschlusses 20. Der Rohrdurchmesser ist derart bemessen, dass das Rohr 23 die zentrische Ausnehmung 202 vollständig umschliesst. Das Rohr 23 erstreckt sich von der Innenseite der Auflageplatte 203 bis über den Gegenverschluss 20 hinaus und im Wesentlichen gleich weit wie eine untere Kante der Bodenhülse 21 der Bodenverankerung 2. Das Rohr 23 dient einerseits als Schmutzabweiser und andererseits als Führung für den Verschlusskern 5. Um eine Verdrehung des Verschlusskerns 5 zu verhindern, ist das Rohr 23 als Vierkantrohr ausgebildet. Alternativ kann ein Rundrohr mit einer Verdrehsicherung verwendet werden. Das Rohr 23 ist als Einzelteil ausgebildet, welches mit der Innenseite der Auflageplatte 203 verbunden ist. Alternativ können die Auflageplatte 203 und das Rohr 23 gemeinsam einstückig miteinander ausgebildet sein.A
Um das Rohr 23 ist ein im Wesentlichen hutförmiger Verschlusskern 5 angeordnet, wobei der Verschlusskern 5 einen Boden 50 und eine umlaufende Seitenwand 51 aufweist. Im eingebauten Zustand ist der Verschlusskern 5 mit einer zum Rohr 23 komplementären Ausnehmung im Boden 50 um das Rohr 23 angeordnet und wird von diesem so geführt, dass nur eine Bewegung in der Längsrichtung möglich ist. Die umlaufende Seitenwand 51 weist Unterbrechungen auf und die Querschnitte durch die Seitenwand 51 in einer Ebene parallel zum Boden, entsprechen den Querschnitten der peripheren Ausnehmungen 201 des Gegenverschlusses 20. Die Länge der Seitenwand 51 ist so bemessen, dass der Boden 50 am Ring 22 anschlägt, wenn die Abschnitte der Seitenwand 51 in die peripheren Ausnehmungen 201 hineinreichen und eine obere Stirnfläche der Seitenwandabschnitte 51 im Wesentlichen fluchtend mit der Oberfläche der Auflageplatte 203 ist. Im Boden 50 des Verschlusskerns 5 sind Entwässerungsöffnungen 52 vorgesehen, durch welche Wasser ablaufen kann, welches durch den Gegenverschluss 20 in den Verschlusskern 5 gelangt ist.A substantially hat-shaped
Am unteren freien Ende des Rohres 23 ist eine Ringplatte 24 angeordnet und zumindest teilweise an diesem fixiert. Ein Anschlag, beispielsweise in der Form eines Splints oder eines Bolzens verhindert, dass die Ringplatte 24 über das freie Ende hinaus, vom Gegenverschluss 20 wegbewegt werden kann. Die Gegenrichtung kann ebenfalls blockiert sein, muss es jedoch nicht. Die Ringplatte 24 dient einer Druckfeder 6 als unterer Anschlag. Der Aussendurchmesser der Ringplatte 24 ist grösser als der Aussendurchmesser der Druckfeder. Die Druckfeder ist zwischen der Ringplatte 24 und dem Verschlusskern 5 angeordnet und bewirkt, dass der Verschlusskern 5, bzw. die Abschnitte der Seitenwand 51 in die peripheren Ausnehmungen 201 des Gegenverschlusses gedrückt werden.An

Alternativ können andere Querschnitte realisiert sein, wie beispielsweise solche mit drei, fünf, sechs oder mehr Kanten. Als weitere Alternative kann auch ein ovaler Querschnitt realisiert sein.Alternatively, other cross-sections can be implemented, such as those with three, five, six or more edges. As a further alternative, an oval cross section can also be implemented.
Als weitere Alternative kann eine Sollbruchschraube anstelle der Ausnehmungen 44, welche sich im Wesentlichen an der Oberfläche des Schraubenschafts erstrecken, auch Ausnehmungen aufweisen, welche sich durch den Schraubenschaft erstrecken. So bildet eine einzelne Ausnehmung, welche sich quer zur Schraubenlängsachse L erstreckt, einen bezüglich des Schraubenschafts stirnseitigen Schlitz, wenn der Schraubenkopf abgetrennt wird. In diesen Schlitz kann dann ein Schlitz-Schraubendreher eingeführt werden, um den Schraubenschaft aus seiner Aufnahme herauszudrehen. Alternativ können zwei oder mehr solcher durchgehender Ausnehmungen regelmässig oder unregelmässig verteilt bezüglich des Umfangs der Schraube angeordnet sein und bilden so unterschiedliche Eingriffsformen für ein entsprechendes Werkzeug nach dem Abtrennen des Schraubenkopfes. Beispielsweise bilden zwei bezügliche der Längsmittelachse L zueinander senkrechte, durchgehende Ausnehmungen, nach dem Abtrennen des Schraubenkopfes eine Eingriffsform für einen Kreuz-Schraubendreher.As a further alternative, instead of the
