Description

The invention relates to a rigid bollard comprising a pedestal and a post, an anchorage for fixing the bottom of the base and a bayonet closure for releasably connecting the base to the pile.

Bollards are vertical piles fixed in the ground. Bollards prevent driving on or leaving traffic areas. In order to enable a temporary driving or leaving a traffic area, folding bollards or plug-in bollards are used. In addition, automatically retractable bollards are known to temporarily release a traffic area.

Furthermore, a distinction is made between flexible and rigid bollards. Flexible bollards have a bottom joint that deflects impact forces on the pole. If it comes to a contact of a vehicle with a flexible bollard, the bollard diffuses in the direction opposite to the force direction and then usually independently re-starting in the initial state. From these flexible bollards rigid bollards are distinguished, which due to their impact load has a barrier function for traffic areas. Fixed bollards are therefore particularly suitable as barriers for traffic areas.

In order to temporarily remove the barrier effect of a rigid bollard, the rigid bollard may have a base anchorable to the ground and a post detachably connectable to the base. The GB 875,635 reveals one rigid bollard and a base anchored in the ground. The conical bollard has at its lower end face on a cylindrical pin, from the lateral surface of which extends radially outward a pin which engages in a bayonet groove of the base. Through a plug-in rotary movement, the pole can be easily connected to the socket and also detached from the socket again.

Based on this prior art, the present invention seeks to provide a rigid bollard, which is suitable for anti-theft, especially of vehicles and trailers.

• eine verschließbare mechanische Verriegelung zwischen dem Sockel und dem Pfahl, eingerichtet um eine Verdrehung des mit dem Sockel verbundenen Pfahls zu blockieren,
• wobei die Verankerung nicht zugänglich ist, wenn der Pfahl mit dem Sockel verbunden und die mechanische Verriegelung verschlossen ist.

This object is achieved in a bollard of the type mentioned by

• a lockable mechanical interlock between the pedestal and the pole, arranged to block rotation of the post connected to the pedestal,
• the anchorage being inaccessible when the pole is connected to the base and the mechanical lock is locked.

For mechanical locking a bolt is used, which can be brought together with a counterpart in a positive and detachable connection. The mechanical interlock between and pole and base is also lockable, so that unauthorized release of the bayonet lock is excluded. In addition, to prevent complete disassembly of the bollard, the anchoring of the base on the ground is not accessible when the Post connected to the base over the bayonet lock and the mechanical lock between the base and the post is closed.

• einen Basküleverschluss mit einer verschiebbaren Riegelstange,
• ein Sperrelement, das mit der Riegelstange in eine formschlüssige Verbindung bringbar ist und
• einen Schließzylinder eingerichtet zum Antrieb der Riegelstange.

A particularly advantageous, theft-proof mechanical lock comprises the following components:

• a cage closure with a sliding latch bar,
• a locking element which can be brought into a positive connection with the locking bar and
• a lock cylinder arranged to drive the locking bar.

The crutch closure, also referred to as a push-rod closure, comprises a locking rod displaceable in the vertical direction of the pile and loaded by its own weight. The locking bar cooperates with its engagement region with a locking element as a counterpart, which can be brought into positive connection with the locking bar. The positive engagement acts transversely to the rotation of the bayonet closure. One at the base, i. The lock cylinder arranged in the box of the mortise lock is designed to drive the locking bar and prevents unauthorized unlocking. Even if the lock cylinder is destroyed, the loaded by its own weight locking bar remains engaged.

In an advantageous embodiment of the invention, the cylinder lock is additionally equipped with a pull protection. The pull protection is a cylinder cover comprising a rotating disk during the closing operation by which the key is inserted into the lock cylinder. The pull protection prevents the lock cylinder from being pulled out of the mortise lock.

The theft protection is further improved when the cage plug is arranged in the interior of the hollow body formed as a pile and the blocking element in the form of a hollow body socket. Constructively advantageous for this purpose, the post designed as a hollow cylinder, wherein the hollow cylinder has an upper closed and a lower open end face. The open end face points in the direction of a bottom plate of the base, on which the blocking element is arranged, which cooperates with the locking bar of the mortar closure.

In order to be able to attach the cage bolt and the lock cylinder in the interior of the pile and out of the way, the cage bolt and the lock cylinder are preferably fastened to a lock carrier which extends in the interior of the hollow cylinder in its longitudinal direction, wherein on the inner shell of the hollow cylinder near the upper end side, a U-shaped bracket is fixed, which is adapted for insertion of an upper portion of the lock carrier between the bracket and the inner shell and wherein on the inner shell of the hollow cylinder in the region of the lower, open end side, a clamping device is attached, which is for fixing the position of a lower Section of the lock carrier is set up in the hollow cylinder.

The clamping device may, for example, comprise a clamping screw which presses the lock carrier against the inner jacket of the hollow cylinder with the aid of a clamping element adjustably arranged on the clamping screw. As an abutment, the clamping screw is supported on a carrier which extends transversely to the longitudinal axis of the hollow cylinder and transversely to the direction of action of the screw in the hollow cylinder. At the ends of the carrier with the inner shell of the hollow cylinder is fixedly connected, for example by welding.

The anchoring to the floor mounting of the base comprises at least one, preferably a plurality of screws and a passage for each screw in the bottom plate of the base. The screw heads are accessible with dissolved pile on the insertion of the pile in the base from above. If the post is connected to the base, it blocks the insertion opening in the base and thus access to the anchoring of the base. Unless the anchoring screws can be screwed directly into the ground, the anchoring also has a screw plug for each screw, each screw plug being insertable into a cylindrical hole in the floor.

The base preferably has a small height of a maximum of 10 cm, so that it can be easily run over by a motor vehicle or trailer with the pole removed. However, it is particularly advantageous if the base is completely or at least partially embedded in the ground. As a result, caused by the pedestal Störkante is completely avoided at best. When removed Stake the insertion in the socket is preferably closed with a lid.

In order to facilitate the production of the mechanical connection between the post and base on the required plug and rotary movement of the pile, at least one handling device is arranged on the outer jacket of the pile. The handling device has, in particular, two handles, which extend radially outward at the upper end of the pile and are fastened diametrically opposite to the outer jacket.

In one embodiment of the invention, the rigid bollard is not only the barrier of a traffic area, but also the direct theft protection of a trailer. For this purpose, a holder with a ball head is permanently attached to the outer shell, in particular welded. The ball head is with a counterpart of a ball coupling, as is customary for car trailer, detachable. The ball head has a standardized diameter of in particular 50 mm. On the drawbar of the trailer is located as a counterpart to the ball a ball socket with a closure. This can be opened by lifting a lever and placed on the ball head. If the ball socket and the ball head are coupled together, the ball socket is rotatably mounted on the ball. In order to prevent lifting of the trailer thus connected to the ball, a protective element is additionally arranged on the outer jacket of the pile. The suspension element preferably comprises a plate arranged above the ball socket whose distance from the ball socket is so small that lifting is precluded.

In order to make the anti-sag element effective only after the coupling of ball and ball socket of the trailer, the anti-sag element is releasably connected to the post, wherein at least one stop element is attached to the post, which can be brought to the anti-sag element such that the detachable Connection between the safety element and the stake with the screwing of the pile is locked in the socket.

In the interest of effective anti-theft protection, the rigid bollard must withstand a high impact load of at least 10,000 Newton, but preferably at least 20,000 Newton. As materials for pedestal and pile are therefore primarily metallic materials, especially steel with galvanized surface into consideration. Depending on the size of the bollard, the base and the post have a wall thickness of at least 3 mm, but preferably of at least 10 mm. The floor on which the bollard is anchored must have a corresponding stability (concrete quality).

The rigid bollard according to the invention will be explained in more detail below with reference to the figures.

The pile (3) and the base (2) are detachably connected to each other by means of a bayonet closure (4). The base (2) is formed in the embodiment of a bottom plate (2a), an intermediate ring (2b) and a cover plate (2c), which are welded together. The cover plate (2c) has an insertion opening (2d) for the pile (3). At the outer periphery of the insertion opening (2d) are two offset by 180 ° incisions (2e). At the downwardly open front side (3a) of the pile (3), a ring (3c) is welded to the has two opposing sides with the incisions (2e) corresponding lugs (3d). The diameter of the insertion opening (2d) corresponds to the diameter of the ring (3c), so that the pile (3) guided by the incisions (2e) and the lugs (3d) in the vertical direction (6) in the base (2) can be inserted , After insertion, the tabs (3d) between the bottom plate (2a) and the cover plate (2c) and can be rotated by a rotation (7) in a clockwise direction, whereby the pile (3) with base (2) is connected. In order to facilitate the connection of the pile (3) to the base (2), two radially outwardly extending handles (8) are fastened to the upper end face (3b) of the pile (3).

Die Verriegelung umfasst einen Basküleverschluss (9a) mit einer in vertikaler Richtung (6) verschiebbaren Riegelstange (9b) mit einem Eingriffsbereich (9c), der mit einem auf der Bodenplatte (2a) des Sockels (2) angeordneten Sperrelement in eine formschlüssige Verbindung bringbar ist. Das Sperrelement verhindert eine Rückdrehung entgegen der Drehrichtung (7) des Pfahls (3), an dessen Innenmantel die mechanische Verriegelung (9) befestigt ist. In dem Kasten (9d) des Basküleverschlusses (9a) ist ein Schließzylinder (9e) angeordnet, der die Riegelstange (9b) antreibt. Wie insbesondere aus Figur 2 erkennbar, ist in dem Mantel des Pfahls (3) eine Zugangsöffnung für den Schließzylinder (9e) eingebracht.

In order to block a reverse rotation of the pole (3) connected to the base (2), the bollard (1) has a closable mechanical lock (9), which is described below with reference to FIG FIGS. 2 and 3 is explained in more detail:

• The mechanical lock (9) is arranged in the interior of the hollow cylinder designed as a post (3), as in FIG. 2 is recognizable. The lock comprises a base bolt closure (9a) with a locking bar (9b) displaceable in the vertical direction (6) and having an engagement region (9c) which can be brought into positive engagement with a blocking element arranged on the bottom plate (2a) of the base (2) , The blocking element prevents a reverse rotation against the direction of rotation (7) of the pile (3), on the inner shell of which the mechanical lock (9) is fastened. In the box (9d) of the Bascule closure (9a), a lock cylinder (9e) is arranged, which drives the locking bar (9b). As in particular from FIG. 2 recognizable, is in the Shell of the pile (3) an access opening for the lock cylinder (9e) introduced.

The mortise lock (9a) with the lock cylinder (9e) is fastened to a lock carrier (10) which extends in the interior of the hollow cylinder in the vertical direction (6) from the upper to the lower end face (3a, 3b). The lock carrier (10) is formed by a rectangular cross-section profile bar. At the upper end face (3b), a U-shaped bracket (11) is attached to the inner shell (3e) of the pile (3). The lock carrier (10) is inserted with an upper portion (10a) between the bracket (11) and the inner shell (3e) ( FIG. 2a ). On the lower end face (3a) of the hollow cylinder, a clamping device (12) for fixing the position of the lower portion (10b) of the lock carrier (10) is provided ( FIG. 2b ). The clamping device (12) comprises a with the inner shell (3e) welded at the ends of the cross member (12a) centrally has a passage for a clamping screw (12b) on which a U-shaped clamping bracket (12c) by means of nuts (12d ) presses against the lower portion (10b) of the lock carrier (10).

For the installation of the lock carrier with the cage bolt, the upper portion (10a) is first inserted into the bracket (11). Only then is brought from the easily accessible lower end face by means of the clamping device (12) of the clamping bracket (12c) with the free legs on the surface of the lower portion (10b) of the lock carrier for conditioning. Through the gap (12e) between the screw tip and the surface of the lower portion (10b), the locking bar (9b) is freely movable in the vertical direction (6) back and forth.

Below the clamping device (12) extends perpendicular to the surface of the lock carrier (10) a guide element (13) for the locking bar (9b).

By turning the lock cylinder (9e), the locking bar (9b) is extended beyond the lower end face (3a) of the pile (3) and comes into positive engagement with the locking element, for example a piece of metal welded onto the base plate (2a), and effectively prevents it reverse rotation. By removing the key from the lock cylinder (9e), the mechanical lock is closed and the pile can not be released from the bollard.

At the same time, the anchoring (5) of the base (2) on the ground is no longer accessible. In the present case, the anchoring takes place with the aid of four screws, which extend through passages in the base plate (2a) and in each case engage in a screw anchor in the ground ( FIG. 1 ). A release of the base (2) from the ground is therefore excluded in the closed and mechanically locked state of the pile (3).

FIGS. 4 a-c show a further embodiment of the bollard (1) according to the invention, with respect to the bayonet closure for detachable connection of the base (2) with the pile (3) and the lockable mechanical lock (9) between the base (2) and the pile ( 3) with the embodiment of the FIGS. 1 to 3 matches. To avoid repetition is therefore on the comments on the first embodiment directed. In addition, on the outer casing (3f) of the pile (3), a holder (14) is welded to a ball head (15) which can be coupled to a counterpart, not shown, of a ball head coupling for trailers.

Above the ball head (15), a hook (16) is welded to the outer casing (3f), in which after hanging the trailer a suspension element (17) is hung. From the FIGS. 4a, b It can be seen that a horizontal portion (17a) of the suspension element (17) at a small distance above the ball head (15), so that the trailer can not be lifted upwards. After locking the pile (3) to the base (2), a lower horizontal portion (17b) of the suspension element (17) engages under a hook (18) welded to the base (2), the lower horizontal portion (17b) passing through the rotation of the post (3) is clockwise engaged with the hook (18). The so by the hooks (16), (18) with the base (2) and the pile (3) connected to the protection element (17) with the screwing of the pile (3) in the base (2) by a on the outer casing (3f ) fixed stop member (19) which blocks movement of the horizontal portion (17b) against the screwing under the hook (18).

From the above functional description of the suspension element (17) it is clear that after the coupling between the ball head (15) and the ball socket on the trailer a slight reverse rotation of the bayonet lock is required to the horizontal portion (17b) of the suspension element (17) with the hook (18) engage and lock by the stop element (19).
