Definitions
- the invention relates to a barrier grid consisting of a number of gleichgeformte bars, which are pivotally connected and at a distance to each other with a hinged to a barrier housing and pivotable in a vertical plane boom and connected to a rail extending parallel to the boom.
- the bars are set at their lower and, if necessary, also at its upper attachment end so that they can swing in the vertically raised barrier tree automatically, not inhibiting against each other.
- Barrier gates should prevent crawling under the barrier barrier when the barrier is closed, or at least provide additional protection for people, especially children, as well as animals.
- a problem with known barrier gratings is that, when opening the barrier, when the barrier grid folds up, virtually every grid bar, that is to say a total of pinch and shear points, presents a risk of injury, especially for children who, for example, want to reach into the grid , represent. Such hazards must be avoided according to the existing European Machinery Directive.
- the object of the invention is to provide a secure barrier grid, in which there are no pinching and shearing, especially when opening the barrier.
- the grid should also be easy to install and easy to repair after possible damage to the bars;
- the bars should be easily replaced or replaced.
- the new barrier grid is intended to be used both as an anti-creep protection and, if required, to be able to offer combined creep and protection against overcrowding.
- the upper and lower ends of the bars are bent in the opposite direction and the upper end is pivotally connected to a guide groove on the boom and the lower end is connected to a in the Distance below and parallel to the boom extending guide rail pivotally connected.
- the bend at both ends of the bars has the consequence that during the opening movement of the barrier and in the open state of the barrier no crushing or shearing between the ends of the bars and the guide groove on the barrier boom or the bar parallel to the guide rail are formed and exist, a risk of injury is thus largely eliminated.
- both ends of the grid bars are also bent; the one bent end of the bars is pivotally connected to a running at a distance below and parallel to the barrier boom guide rail and the other cranked end the grid bars are pivotally connected to a guide rail extending at a distance above and parallel to the boom, and each grid bar is pivotally connected to the barrier boom at a location between and spaced from its two bent ends.
- This embodiment of the bars is particularly suitable for barriers that are to be equipped with both an anti-crawl and with a safety guard.
- only one end of the bars can be bent, and this cranked end can be pivotally connected to a spaced below and parallel to the barrier boom guide rail, while the other end of the bars projecting freely from the boom can stand up; each of the bars is connected at one point between and at a distance from its ends pivotally connected to the barrier boom.
- a foot part can be formed, with which each grid bar can be mounted pivotably in a guide rail running parallel to the boom or in a guide groove on the barrier boom.
- spacer bars between the cranked ends of the grid bars may be inserted into the guide groove on the barrier boom or into the guide rails.
- the length of the spacer bars is selected accordingly, the distance of the bars to each other can be changed as needed.

- the spacer strips are preferably held by engagement means in the guide rails or in the guide groove and have recesses with which a formed on the bent end of a lattice bar foot can be engaged.
- the spacer strips may be U-shaped and held by inwardly curved side walls of the guide rails in the guide rails; in their side walls, the spacer strips may have recesses with which the trained at the bent end of a lattice bar foot can be engaged. This allows a very simple placement of the barrier grid.
- the foot at the bent ends of the bars is preferably formed transversely and has transversely to the cranked end and oppositely directed connecting pin, which can be brought into engagement with the recesses of a spacer bar.
- bars can be inserted one after the other in the spacer bars in a very simple manner.

- the connecting piece is for this purpose preferably arranged laterally on the barrier boom about an axis and it has two mutually oppositely directed extensions, with each of which one end of the center pieces of a lattice bar of the second embodiment is connected.
- the axis about which the connecting piece is pivotable on the boom is formed so that there is a gap between the barrier boom and the connecting piece, it is avoided that scratches occur on the barrier boom or on the connecting piece.
- the end pieces rod-shaped and the middle pieces are tubular, and the end pieces can be advantageously connected with its remote from the bent end, straight, rod-shaped end by a snap connection with one end of a tubular center piece.
- the bars can be so quickly and easily assembled without the aid of a tool from the end pieces and middle pieces and are hung with the foot of their bent ends in a guide on the boom and in a parallel to the boom extending guide rail. If once individual bars are damaged, so they can be easily replaced and replaced.
- the end pieces of the bars may be tubular and the centerpieces may be rod-shaped, wherein in turn the end pieces are connected with their remote from the bent end, straight end by a snap connection with one end of a central piece.

Schrankengitter sollen das Unterkriechen des Schrankenbaumes bei geschlossener Schranke verhindern oder zumindest einen zusätzlichen Schutz für Personen, besonders für Kinder, und auch Tiere bieten.Barrier gates should prevent crawling under the barrier barrier when the barrier is closed, or at least provide additional protection for people, especially children, as well as animals.
Ein Problem bei bekannten Schrankengittern ist, dass sich beim Öffnen der Schranke, wenn sich das Schrankengitter zusammenfaltet, praktisch an jedem Gitterstab, also insgesamt eine Vielzahl von Quetsch- und Scherstellen ergeben, die eine Verletzungsgefahr besonders für Kinder, die beispielsweise in das Gitter greifen wollen, darstellen. Solche Gefahrenquellen müssen nach der bestehenden europäischen Maschinenrichtlinie vermieden werden.A problem with known barrier gratings is that, when opening the barrier, when the barrier grid folds up, virtually every grid bar, that is to say a total of pinch and shear points, presents a risk of injury, especially for children who, for example, want to reach into the grid , represent. Such hazards must be avoided according to the existing European Machinery Directive.
Häufig wird es auch als notwendig angesehen, eine Schranke nicht nur mit einem Unterkriechschutz in Form eines Schrankengitters sondern zusätzlich auch mit einem Schrankengitter als Übersteigschutz auszustatten. Zur Befestigung der Gitterstäbe eines Übersteigschutzes ist es bekannt, die Gitterstäbe zu durchbohren und mit Schrauben am Schrankenbaum zu befestigen. Da die Gitterstäbe meistens aus Metall, vorzugsweise Aluminium, sind, müssen am Schrankenbaum zusätzliche Gleitschienen angebracht werden, um ein Verkratzen der Gitterstäbe und des Schrankenbaumes zu verhindern.Often it is also considered necessary to equip a barrier not only with a creep in the form of a barrier grid but also with a barrier grid as Übersteigschutz. To attach the bars of a climb protection, it is known to pierce the bars and fasten with screws on the boom. Since the bars are usually made of metal, preferably aluminum, additional slide rails must be attached to the barrier boom to prevent scratching of the bars and the barrier boom.
Aufgabe der Erfindung ist es, ein sicheres Schrankengitter zu schaffen, bei dem sich vor allem beim Öffnen der Schranke keine Quetsch- und Scherstellen ergeben. Das Gitter soll außerdem einfach zu montieren und nach einer möglichen Beschädigung der Gitterstäbe leicht zu reparieren sein; die Gitterstäbe sollen leicht ausgewechselt oder ersetzt werden können. Das neue Schrankengitter soll sowohl als Unterkriechschutz einsetzbar sein als auch bei Bedarf kombiniert Unterkriech- und Übersteigschutz bieten können.The object of the invention is to provide a secure barrier grid, in which there are no pinching and shearing, especially when opening the barrier. The grid should also be easy to install and easy to repair after possible damage to the bars; The bars should be easily replaced or replaced. The new barrier grid is intended to be used both as an anti-creep protection and, if required, to be able to offer combined creep and protection against overcrowding.
Erfindungsgemäß wird dies erreicht mit einem Schrankengitter nach Anspruch 1.This is achieved according to the invention with a barrier grid according to
Nach der Erfindung ist das Ende der Gitterstäbe, mit dem sie mit einer parallel zum Schrankenbaum verlaufende Führungsschiene oder mit einer Führungsnut am Schrankenbaum verschwenkbar verbunden sind, als abgekröpftes Ende ausgebildet. Durch die abgekröpften Enden der Gitterstäbe werden Scherstellen an der im Abstand und parallel zum Schrankenbaum verlaufenden Führungsschiene vermieden.According to the invention, the end of the bars, with which they are pivotally connected to a parallel to the barrier boom guide rail or with a guide on the boom, formed as a cranked end. By the bent ends of the bars shear points are avoided at the running in the distance and parallel to the barrier rail guide rail.
Nach einer ersten Ausführungsform der Erfindung, die besonders vorteilhaft für ein Schrankengitter als Unterkriechschutz anwendbar ist, sind die oberen und unteren Enden der Gitterstäbe in entgegengesetzter Richtung abgekröpft und das obere Ende ist mit einer Führungsnut am Schrankenbaum verschwenkbar verbunden und das untere Ende ist mit einer im Abstand unterhalb und parallel zum Schrankenbaum verlaufenden Führungsschiene verschwenkbar verbunden. Die Abkröpfung an beiden Enden der Gitterstäbe hat zur Folge, dass während der Öffnungsbewegung der Schranke und im geöffneten Zustand der Schranke keine Quetsch- oder Scherstellen zwischen den Enden der Gitterstäbe und der Führungsnut am Schrankenbaum bzw. der zum Schrankenbaum parallel verlaufenden Führungsschiene entstehen und bestehen, eine Verletzungsgefahr somit weitgehendst ausgeschaltet ist.According to a first embodiment of the invention, which is particularly advantageous for a barrier grid as creeping applicable, the upper and lower ends of the bars are bent in the opposite direction and the upper end is pivotally connected to a guide groove on the boom and the lower end is connected to a in the Distance below and parallel to the boom extending guide rail pivotally connected. The bend at both ends of the bars has the consequence that during the opening movement of the barrier and in the open state of the barrier no crushing or shearing between the ends of the bars and the guide groove on the barrier boom or the bar parallel to the guide rail are formed and exist, a risk of injury is thus largely eliminated.
Nach einer anderen Ausführungsform der Erfindung sind ebenfalls beide Enden der Gitterstäbe abgekröpft; das eine abgekröpfte Ende der Gitterstäbe ist mit einer im Abstand unterhalb und parallel zum Schrankenbaum verlaufenden Führungsschiene verschwenkbar verbunden und das andere abgekröpfte Ende der Gitterstäbe ist mit einer im Abstand oberhalb und parallel zum Schrankenbaum verlaufenden Führungsschiene verschwenkbar verbunden, und jeder Gitterstab ist an einer Stelle zwischen und im Abstand zu seinen beiden abgekröpften Enden verschwenkbar mit dem Schrankenbaum verbunden. Diese Ausführungsform der Gitterstäbe eignet sich besonders für Schranken, die sowohl mit einem Unterkriechschutz als auch mit einem Übersteigschutz ausgerüstet werden sollen.According to another embodiment of the invention, both ends of the grid bars are also bent; the one bent end of the bars is pivotally connected to a running at a distance below and parallel to the barrier boom guide rail and the other cranked end the grid bars are pivotally connected to a guide rail extending at a distance above and parallel to the boom, and each grid bar is pivotally connected to the barrier boom at a location between and spaced from its two bent ends. This embodiment of the bars is particularly suitable for barriers that are to be equipped with both an anti-crawl and with a safety guard.
Nach einer einfacheren Ausführungsform des Schrankengitters mit Unterkriech- und Übersteigschutz kann nur das eine Ende der Gitterstäbe abgekröpft sein, und dieses abgekröpfte Ende kann mit einer im Abstand unterhalb und parallel zum Schrankenbaum verlaufenden Führungsschiene verschwenkbar verbunden sein, während das andere Ende der Gitterstäbe freikragend vom Schrankenbaum nach oben stehen kann; jeder der Gitterstäbe ist dabei an einer Stelle zwischen und im Abstand zu seinen Enden verschwenkbar mit dem Schrankenbaum verbunden.According to a simpler embodiment of the barrier grid with creeping and excess protection, only one end of the bars can be bent, and this cranked end can be pivotally connected to a spaced below and parallel to the barrier boom guide rail, while the other end of the bars projecting freely from the boom can stand up; each of the bars is connected at one point between and at a distance from its ends pivotally connected to the barrier boom.
Vorteilhaft kann an jedem abgekröpften Ende der Gitterstäbe ein Fußteil angeformt sein, mit dem jeder Gitterstab in einer parallel zum Schrankenbaum verlaufenden Führungsschiene oder in einer Führungsnut am Schrankenbaum verschwenkbar eingehängt werden kann.Advantageously, at each bent end of the bars, a foot part can be formed, with which each grid bar can be mounted pivotably in a guide rail running parallel to the boom or in a guide groove on the barrier boom.
Um die Gitterstäbe in der Führungsnut am Schrankenbaum bzw. in der oder den Führungsschienen zu platzieren und an ihrem Platz zu halten, können Abstandsleisten zwischen den abgekröpften Enden der Gitterstäbe in die Führungsnut am Schrankenbaum bzw. in die Führungsschienen eingeführt werden. Indem die Länge der Abstandsleisten entsprechend gewählt wird, kann der Abstand der Gitterstäbe zueinander nach Bedarf verändert werden. Um zu verhindern, dass kleine Tiere zwischen die Gitterstäbe kriechen können oder für den Einsatz des Schrankengitters als Wildschutzgitter, wird der Abstand der Gitterstäbe eher eng gewählt werden, bei anderen Anwendungen kann ein eher weiter Abstand der Gitterstäbe vorteilhaft sein.To place the grid bars in the guide groove on the barrier boom or in the guide rail (s) and hold it in place, spacer bars between the cranked ends of the grid bars may be inserted into the guide groove on the barrier boom or into the guide rails. By the length of the spacer bars is selected accordingly, the distance of the bars to each other can be changed as needed. To avoid that small animals can crawl between the bars or for the use of the barrier grid as a game guard, the distance of the bars will be rather narrow, in other applications, a rather wide distance of the bars may be advantageous.
Die Abstandsleisten werden vorzugsweise durch Eingriffsmittel in den Führungsschienen bzw. in der Führungsnut gehalten und weisen Ausnehmungen auf, mit denen ein am abgekröpften Ende eines Gitterstabes ausgebildetes Fußteil in Eingriff gebracht werden kann.The spacer strips are preferably held by engagement means in the guide rails or in the guide groove and have recesses with which a formed on the bent end of a lattice bar foot can be engaged.
Die Abstandsleisten können U-förmig ausgebildet sein und durch nach innen gebogene Seitenwände der Führungsschienen in den Führungsschienen gehalten sein; in ihren Seitenwänden können die Abstandsleisten Ausnehmungen aufweisen, mit denen das am abgekröpften Ende eines Gitterstabes ausgebildete Fußteil in Eingriff gebracht werden kann. Damit wird eine sehr einfache Bestückung des Schrankengitters ermöglicht.The spacer strips may be U-shaped and held by inwardly curved side walls of the guide rails in the guide rails; in their side walls, the spacer strips may have recesses with which the trained at the bent end of a lattice bar foot can be engaged. This allows a very simple placement of the barrier grid.
Das Fußteil an den abgekröpften Enden der Gitterstäbe ist bevorzugt querstehend angeformt und weist quer zum abgekröpften Ende und einander entgegengesetzt gerichtete Verbindungszapfen auf, die mit den Ausnehmungen einer Abstandsleiste in Eingriff gebracht werden können. Nachdem die Abstandsleisten in der benötigten Zahl in die Führungsschiene eingeschoben wurden, können in sehr einfacher Weise Gitterstäbe nacheinander in die Abstandsleisten eingesetzt werden. Dabei werden die Verbindungszapfen des Fußteils zunächst noch in Richtung der Führungsschiene bzw. der Abstandsleisten gehalten und können durch Drehen um 90° in den Ausnehmungen einer Abstandsleiste und damit in der Führungsschiene verankert werden.The foot at the bent ends of the bars is preferably formed transversely and has transversely to the cranked end and oppositely directed connecting pin, which can be brought into engagement with the recesses of a spacer bar. After the spacer bars have been inserted in the required number in the guide rail, bars can be inserted one after the other in the spacer bars in a very simple manner. The connecting pins of the foot part are initially held in the direction of the guide rail or the spacer strips and can be anchored by turning by 90 ° in the recesses of a spacer bar and thus in the guide rail.
Wenn ein Verbindungsstab mit seinem einen Ende mit dem dem Schrankengehäuse zugewandten Ende einer im Abstand unterhalb und parallel zum Schrankenbaum verlaufenden Führungsschiene in einem ersten Drehpunkt und mit seinem anderen Ende über einen Abstandhalter mit dem Schrankengehäuse in einem weiteren Drehpunkt gelenkig verbunden ist, erhält das Schrankengitter mehr Stabilität und es wird auch bei schnellen Öffnungs- und Schließbewegungen der Schranke ein störendes Pendeln des Schrankengitters verhindert. Durch entsprechende Wahl der Höhe H des Drehpunktes des Verbindungsstabes am Schrankengehäuse und/oder der Länge L des Verbindungsstabes, kann erreicht werden, dass auch bei geöffneter Schranke die Gitterstäbe nicht direkt aufeinander liegen, sondern ein definierter Abstand zwischen ihnen verbleibt, wodurch Quetschstellen zwischen den Gitterstäben vermieden werden. Der Verbindungsstab verhindert außerdem, dass das Schrankengitter bei geschlossener Schranke manuell gefaltet und so ein an sich unerlaubter Durchgang am Schrankenbaum geschaffen werden kann.When a connecting rod is pivotally connected at one end to the barrier housing facing the end of a spaced below and parallel to the boom extending guide rail in a first pivot point and with its other end via a spacer to the barrier housing in a further pivot point, the barrier grid gets more Stability and it is prevented even with rapid opening and closing movements of the barrier disturbing oscillation of the barrier grid. By appropriate choice of the height H of the pivot point of the connecting rod on the barrier housing and / or the length L of the connecting rod, it can be achieved that even when the barrier is open, the bars are not directly adjacent to each other, but a defined distance between they remain, which squeaks between the bars are avoided. The connecting rod also prevents the barrier grid from being manually folded when the barrier is closed, thus creating an inherently unauthorized passage on the barrier boom.
Nach einer Ausführungsform der Erfindung besteht jeder Gitterstab vorzugsweise aus drei Einzelteilen, nämlich zwei Endstücken und einem Mittelstück; dabei sind die Endstücke an ihrem einen Ende abgekröpft und an ihrem anderen Ende gerade verlaufend ausgebildet und zwei Endstücke sind mit ihrem geraden Ende mit jeweils einem Ende des durchgehend gerade ausgebildeten Mittelstücks verbunden.According to one embodiment of the invention, each grid bar preferably consists of three individual parts, namely two end pieces and a center piece; while the end pieces are bent at one end and straight at its other end formed straight and two end pieces are connected with their straight end with one end of the continuous straight center piece.
Nach einer zweiten Ausführungsform besteht jeder Gitterstab aus fünf Einzelteilen, nämlich zwei Endstücken mit einem abgekröpften Ende und einem gerade verlaufenden Ende, zwei durchgehend gerade ausgebildeten Mittelstücken und einem Verbindungsstück; jedes Endstück ist mit seinem vom abgekröpften Ende abgewandten, geraden Ende mit einem Ende eines durchgehend gerade ausgebildeten Mittelstücks verbunden, und das andere Ende jedes durchgehend gerade ausgebildeten Mittelstücks ist mit einem am Schrankenbaum angelenkten Verbindungsstück verbunden. Mit dieser Ausführungsform eines Gitterstabes lassen sich vorteilhaft und in einfacher Weise Schrankengitter mit sowohl einem Unterkriech- als auch einem Übersteigschutz zusammenstellen.According to a second embodiment, each grid bar consists of five individual parts, namely two end pieces with a bent end and a straight end, two continuous straight center pieces and a connecting piece; each end piece is connected with its straight end facing away from the bent end to one end of a continuous straight center piece, and the other end of each continuously straight middle piece is connected to a connecting piece hinged to the barrier arm. With this embodiment of a grid bar can be advantageous and easily put together barrier grid with both a creep as well as a safety cover.
Das Verbindungsstück wird dazu vorzugsweise seitlich am Schrankenbaum um eine Achse verschwenkbar angeordnet und es weist zwei einander entgegengesetzt gerichtete Fortsätze auf, mit denen jeweils ein Ende der Mittelstücke eines Gitterstabes der zweiten Ausführungsform verbunden wird.The connecting piece is for this purpose preferably arranged laterally on the barrier boom about an axis and it has two mutually oppositely directed extensions, with each of which one end of the center pieces of a lattice bar of the second embodiment is connected.
Wenn die Achse, um die das Verbindungsstück am Schrankenbaum verschwenkbar ist, so ausgebildet ist, dass zwischen dem Schrankenbaum und dem Verbindungsstück ein Abstand besteht, so wird vermieden, dass am Schrankenbaum oder am Verbindungsstück Verkratzungen entstehen.If the axis about which the connecting piece is pivotable on the boom, is formed so that there is a gap between the barrier boom and the connecting piece, it is avoided that scratches occur on the barrier boom or on the connecting piece.
Bevorzugt sind nach der ersten, dreiteiligen Ausführungsform der Gitterstäbe die Endstücke stabförmig und die Mittelstücke rohrförmig ausgebildet, und die Endstücke können vorteilhaft mit ihrem vom abgekröpften Ende abgewandten, geraden, stabförmigen Ende durch eine Schnappverbindung mit jeweils einem Ende eines rohrförmigen Mittelstücks verbunden werden. Die Gitterstäbe können so ohne Zuhilfenahme eines Werkzeugs sehr einfach und schnell aus den Endstücken und Mittelstücken zusammengefügt werden und auch mit dem Fußteil ihrer abgekröpften Enden in eine Führungsnut am Schrankenbaum und in eine parallel zum Schrankenbaum verlaufende Führungsschiene eingehängt werden. Sollten einmal einzelne Gitterstäbe beschädigt sein, so können diese in einfacher Weise ausgetauscht und ersetzt werden. Die Schnappverbindungen eines beschädigten Gitterstabes zwischen den Endstücken und dem Mittelstück werden gelöst, wonach die Endstücke, wieder ohne Zuhilfenahme eines Werkzeugs, aus der Führungsnut am Schrankenbaum bzw. aus der Führungsschiene herausgelöst werden können und ein neuer Gitterstab in umgekehrter Reihenfolge montiert werden kann.Preferably, according to the first, three-part embodiment of the bars, the end pieces rod-shaped and the middle pieces are tubular, and the end pieces can be advantageously connected with its remote from the bent end, straight, rod-shaped end by a snap connection with one end of a tubular center piece. The bars can be so quickly and easily assembled without the aid of a tool from the end pieces and middle pieces and are hung with the foot of their bent ends in a guide on the boom and in a parallel to the boom extending guide rail. If once individual bars are damaged, so they can be easily replaced and replaced. The snap connections of a damaged grid bar between the end pieces and the center piece are released, after which the end pieces, again without the aid of a tool, can be removed from the guide groove on the barrier boom or from the guide rail and a new grid bar can be mounted in reverse order.
Alternativ können die Endstücke der Gitterstäbe rohrförmig und die Mittelstücke stabförmig ausgebildet sein, wobei wiederum die Endstücke mit ihrem vom abgekröpften Ende abgewandten, geraden Ende durch eine Schnappverbindung mit jeweils einem Ende eines Mittelstücks verbunden werden.Alternatively, the end pieces of the bars may be tubular and the centerpieces may be rod-shaped, wherein in turn the end pieces are connected with their remote from the bent end, straight end by a snap connection with one end of a central piece.
Nach der zweiten, fünfteiligen Ausführungsform der Gitterstäbe sind vorzugsweise beide Endstücke und die einander entgegengesetzt gerichteten Fortsätze des Verbindungsstücks stabförmig und beide Mittelstücke eines Gitterstabes rohrförmig ausgebildet und die Endstücke sind mit ihrem vom abgekröpften Ende abgewandten, geraden Ende mit dem einen Ende eines Mittelstücks verbunden, und das andere Ende jedes Mittelstücks ist mit jeweils einem der Fortsätze eines Verbindungsstücks durch eine Schnappverbindung verbunden. Auch diese Ausführungsform der Gitterstäbe lässt sich schnell und ohne Zuhilfenahme eines Werkzeugs aus seinen Einzelteilen zusammensetzen und am Schrankenbaum sowie an den Führungsschienen zu einer Schranke mit Unterkriech- und Übersteigschutz montieren. Einzelne, beschädigte Gitterstäbe können schnell und auf einfache Weise gegen neue Gitterstäbe ausgetauscht werden.According to the second, five-part embodiment of the bars are preferably both end pieces and the oppositely directed extensions of the connecting rod rod-shaped and both middle pieces of a grid bar tubular and the end pieces are connected with its remote from the bent end, straight end to the one end of a central piece, and the other end of each central piece is connected to a respective one of the extensions of a connector by a snap connection. Also, this embodiment of the bars can be composed quickly and without the aid of a tool from its individual parts and mounted on the boom and on the guide rails to a barrier with creeping and Übersteigschutz. Single, damaged bars can quickly and easily replaced with new bars.
Alternativ können beide Endstücke und die entgegengesetzt gerichteten Fortsätze des Verbindungsstücks rohrförmig und beide Mittelstücke eines Gitterstabes stabförmig ausgebildet sein und die Endstücke können mit ihrem vom abgekröpften Ende abgewandten, geraden Ende mit dem einen Ende eines Mittelstücks durch eine Schnappverbindung verbunden sein, während das andere Ende jedes Mittelstücks mit jeweils einem der rohrförmigen Fortsätze eines Verbindungsstücks ebenfalls durch eine Schnappverbindung verbunden sein kann.Alternatively, both end pieces and the oppositely directed extensions of the connector tubular and both centers of a grid bar may be rod-shaped and the end pieces may be connected with its remote from the bent end, straight end to one end of a centerpiece by a snap connection, while the other end of each Center piece with one of the tubular extensions of a connector can also be connected by a snap connection.
Die Schnappverbindungen an einem Gitterstab können gebildet werden, indem an dem vom abgekröpften Ende abgewandten, gerade verlaufenden Ende jedes Endstücks, das mit einem Mittelstück verbunden werden soll, mindestens eine federnd nachgebende Ausbiegung mit einem nach außen weisenden, zapfenförmigen Vorsprung vorgesehen ist und beide Enden jedes Mittelstücks jeweils mindestens ein seitliches Eingriffsloch für den zapfenförmigen Vorsprung der Ausbiegung am gerade verlaufenden Ende eines Endstücks aufweisen und die Enden eines Mittelstücks über jeweils ein die Ausbiegung mit zapfenförmigem Vorsprung aufweisendes Ende eines Endstücks zu schieben ist, bis der zapfenförmige Vorsprung in ein Eingriffsloch am Mittelstück einrastet Mit einer solchen Schnappverbindung können die Gitterstäbe ohne Zuhilfenahme eines Werkzeugs zusammengefügt werden. Um die Schnappverbindungen zu lösen, genügt ein sehr einfaches Werkzeug, vergleichbar einer Pinzette, mit dem der zapfenförmige Vorsprung eines Endstücks aus dem Eingriffsloch des Mittelstücks herausgedrückt werden kann, so dass der betreffende Gitterstab zerlegt werden kann.The snap-fit connections on a grid bar can be formed by providing at least one resilient bend with an outwardly facing peg-shaped projection on the straight end of each end piece to be connected to a center at the end remote from the cranked end and both ends of each Centerpiece each having at least one lateral engagement hole for the peg-shaped projection of the bend at the straight end of an end piece and the ends of a center piece to slide over each of a deflection with zapfenförmigem projection exhibiting end of an end piece until the pin-shaped projection engages in an engagement hole on the center piece With such a snap connection, the bars can be assembled without the aid of a tool. In order to solve the snap connections, a very simple tool, comparable to a pair of tweezers, with which the peg-shaped projection of an end piece can be pushed out of the engagement hole of the center piece, so that the relevant grid bar can be disassembled is sufficient.
Selbstverständlich können die Schnappverbindungen auch gebildet werden, indem in äquivalenter Weise die Ausbiegung mit dem zapfenförmigen Vorsprung an den Enden eines jeden Mittelstücks und das Eingnifisloch für den zapfenförmigen Vorsprung am gerade verlaufenden Ende jedes Endstücks ausgebildet werden.Of course, the snap connections can also be formed by equivalently forming the deflection with the peg-shaped projection at the ends of each central piece and the peg-shaped projection entry hole at the straight end of each end piece.
Nach der zweiten Ausführungsform der Gitterstäbe ist an dem vom abgekröpften Ende abgewandten, gerade verlaufend ausgebildeten Ende beider Endstücke und an den gerade verlaufenden Fortsätzen des Verbindungsstücks eines Gitterstabes mindestens eine federnd nachgebende Ausbiegung mit einem nach außen weisenden, zapfenförmigen Vorsprung vorgesehen, und beide Enden jedes Mittelstücks weisen jeweils mindestens ein seitliches Eingriffsloch für den zapfenförmigen Vorsprung einer der Ausbiegungen auf; die Enden eines Mittelstücks werden jeweils über das die Ausbiegung mit zapfenförmigem Vorsprungs aufweisende Ende der Endstücke und der Fortsätze eines Verbindungsstücks geschoben, bis der zapfenförmige Vorsprung in ein Eingriffsloch am Mittelstück einrastet.According to the second embodiment of the grid bars, at least one resilient deflection with an outwardly directed peg-shaped projection is provided on the straight end of both end pieces facing away from the bent end and on the straight extensions of the connecting piece of a grid bar, and both ends of each center piece each have at least one lateral engagement hole for the peg-shaped projection of one of the bends; the ends of a center piece are respectively slid over the end of the end pieces having the buckle-shaped projection and the extensions of a connecting piece until the pin-shaped projection engages in an engagement hole on the center piece.
Auch bei dieser Ausführungsform ist die oben erwähnte äquivalente Ausführung der Schnappverbindung möglich.Also in this embodiment, the above-mentioned equivalent embodiment of the snap connection is possible.
Vorteilhaft ist der Durchmesser der gerade verlaufend ausgebildeten, stabförmigen Endstücke und der stabförmigen Fortsätze des Verbindungsstücks an der federnd nachgebenden Ausbiegung im ungespannten Zustand dieser Ausbiegung größer als der offene Durchmesser eines Mittelstücks. Im zusammengebauten Zustand eines Gitterstabes ist dann die Ausbiegung vorgespannt und es besteht eine spielfreie Verbindung zwischen Endstücken, Mittelstücken bzw. Verbindungsstück.Advantageously, the diameter of the straight extending, rod-shaped end pieces and the rod-shaped extensions of the connecting piece on the resiliently yielding deflection in the untensioned state of this deflection is greater than the open diameter of a central piece. In the assembled state of a grid bar then the deflection is biased and there is a backlash-free connection between end pieces, center pieces or connector.
Die Schnappverbindungen können sicherer gemacht werden, indem das gerade, stabförmige Ende der Endstücke bzw. die geraden Fortsätze des Verbindungsstücks, die mit einem Mittelstück verbunden werden sollen, mit zwei einander gegenüberliegenden, federnd nachgebenden Ausbiegungen mit je einem zapfenförmigen Vorsprung ausgebildet sind und die beiden Enden der geraden Mittelstücke zwei einander gegenüberliegende Eingriffslöcher für die zapfenförmigen Vorsprünge an den Endstücken und an den Fortsätzen eines Verbindungsstücks aufweisen. Auch hier ist die erwähnte äquivalente Lösung möglich.The snap connections can be made safer by the straight, rod-shaped end of the end pieces or the straight extensions of the connecting piece, which are to be connected to a center piece, formed with two opposing, resilient buckles, each with a pin-shaped projection and the two ends the straight centerpieces have two mutually opposite engagement holes for the peg-shaped projections on the end pieces and on the extensions of a connecting piece. Again, the mentioned equivalent solution is possible.
Bei einer Schranke mit Unterkriech- und Übersteigschutz kann eine Reihe von Verbindungsstücken seitlich am Schrankenbaum angeordnet sein. Jedes Verbindungsstück ist dabei beabstandet zum Schrankenbaum um eine Achse verschwenkbar und weist einander entgegengesetzt gerichtete Fortsätze auf, mit denen die Mittelstücke eines Gitterstabes verbunden sind; die Verbindungsstücke am Schrankenbaum sind dabei entsprechend dem gewünschten Abstand der Gitterstäbe beabstandet.In a barrier with crawl and climb protection, a number of connectors can be arranged laterally on the barrier boom. Each connector is spaced from the barrier boom pivotable about an axis and has mutually oppositely directed extensions with which the centerpieces of a lattice bar are connected; The connectors on the boom are spaced according to the desired spacing of the bars.
Alle Einzelteile der Gitterstäbe, also die Endstücke, die Mittelstücke und die Verbindungsstücke, können aus einem Kunststoff bestehen oder die Endstücke und die Verbindungsstücke können aus einem Kunststoff und die Mittelstücke können aus Aluminium bestehen. Ein Schrankengitter wird damit leichtgängig, ist von leichtem Gewicht und bewegt sich ohne nennenswerte Geräuschentwicklung.All items of the bars, so the end pieces, the center pieces and the connectors, may be made of a plastic or the end pieces and the connectors may be made of a plastic and the centerpieces may be made of aluminum. A barrier grid is thus easy, is lightweight and moves without significant noise.
Wenn die Endstücke und die Verbindungsstücke der Gitterstäbe aus einem Kunststoff und die Mittelstücke der Gitterstäbe aus Edelstahl bestehen, sind die Gitterstäbe besonders widerstandsfähig gegen Witterungseinflüsse.If the end pieces and the connecting pieces of the bars are made of a plastic and the centers of the bars are made of stainless steel, the bars are particularly resistant to weathering.
Um Beschädigungen oder Verletzungen zu vermeiden kann zumindest die im Abstand unterhalb und parallel zum Schrankenbaum verlaufende Führungsschiene auf ihrer gesamten Länge mit einem Kantenschutz überzogen sein.In order to avoid damage or injury, at least the guide rail running at a distance below and parallel to the barrier boom can be covered over its entire length with edge protection.
Der Kantenschutz kann ein wulstförmiges Profil aufweisen, an dem Einbuchtungen vorgesehen sind, mit denen an der Führungsschiene vorgesehene Eingriffsmittel in Eingriff bringbar sind.The edge protector may have a bead-shaped profile, on which indentations are provided, with which engaging means provided on the guide rail can be brought into engagement.
Ein weiterer Vorteil des erfindungsgemäßen Schrankengitters ist, dass sich seine Einzelteile - wie Gitterstäbe, Endstücke, Mittelstücke und Verbindungsstücke der Gitterstäbe, Führungsschienen, Abstandsleisten und Verbindungsstab samt Abstandhalter - sehr kompakt für einen Transport und eine Montage vor Ort verpacken lassen; es werden so Transportraum und Transportkosten, auch wegen des reduzierten Gewichts, eingespart; die Montage vor Ort ist, wie beschrieben, sehr einfach.Another advantage of the barrier grid according to the invention is that its individual parts - such as bars, end pieces, centerpieces and connectors of the bars, guide rails, spacer strips and connecting rod together with spacers - very compact packaging for transport and assembly on site; it saves so transport space and transport costs, also because of the reduced weight; the installation on site is, as described, very simple.

Nach dieser Ausführungsform der Erfindung besteht jeder Gitterstab 4 aus drei Einzelteilen, nämlich zwei Endstücken 11 und einem Mittelstück 12, die zusammenmontiert einen Gitterstab 4 ergeben.
In glatt äquivalenter Weise können die Schnappverbindungen auch hergestellt werden, indem die Ausbiegungen mit den zapfenförmigen Vorsprüngen an den Enden der Mittelstücke der Gitterstäbe und die Eingriffslöcher für die zapfenförmigen Vorsprünge an den gerade verlaufenden Enden der Endstücke vorgesehen werden.In a smooth equivalent manner, the snap connections can also be made by providing the bumps with the peg-shaped projections at the ends of the centers of the grid bars and the engagement holes for the peg-shaped projections at the straight ends of the ends.
Ein Gitterstab 4 kann so auf sehr einfache Weise, ohne Zuhilfenahme irgendeines Werkzeugs aus zwei Endstücken 11 und einem Mittelstück 12 zusammengefügt werden und mit den das obere und untere Ende des Gitterstabs 4 bildenden, abgekröpften Enden 13 der Endstücke 11 ebenso einfach, ohne Zuhilfenahme eines Werkzeugs in die Führungsnut 5 am Schrankenbaum 2 und in die Führungsschiene 6 (siehe

Ein besonderer Vorteil der erfindungsgemäßen Schrankengitter 3, 3' ist, dass die, wie beschrieben, sehr einfache, werkzeuglose Montage der Gitter ohne weiteres vor Ort erfolgen kann. Die Einzelteile, wie Endstücke 11, Mittelstücke 12, Führungsschienen 6, 6', Verbindungsstücke 20, Verbindungsstab 7, Abstandhalter 8, Abstandsleisten 17, lassen sich für einen Transport in zerlegtem Zustand sehr kompakt verpacken und vor Ort, wie beschrieben, montieren; es werden so der benötigte Transportraum und die Transportkosten deutlich reduziert. Indem als Material für die Endstücke 11 und die Verbindungsstücke 20 der Gitterstäbe 4, 4' Kunststoff und für ihre Mittelstücke 12 Aluminium gewählt wird, wird Gewicht eingespart und die Transportkosten werden weiter gesenkt. Außerdem werden die Bewegungen der Schranke bzw. der Schrankengitter 3, 3' geräuscharm, d.h. leise im Vergleich zu bekannten Schrankengittern. Bei Bedarf kann als Material für die Mittelstücke 12 der Gitterstäbe 4, 4' auch Edelstahl gewählt werden; die Gitterstäbe werden damit widerstandfähiger z.B. gegen Witterungseinflüsse.A particular advantage of the
