Abstract

A lockable barrier comprises a support (1) adapted to be firmly mounted in position in or on the ground and a member (8) pivotally mounted on the support, this member being movable between a substantially horizontal position and a substantially vertical position, this member also being provided with lockable means (18) which engage the support when the member is in the substantially vertical position so as to retain the member in that position. <IMAGE>

Description

Improvements in or relating to a lockable barrier THIS INVENTION relates to a lockable barrier and more particularly relates to a lockable barrier of the type which may be utilised to secure access to a parking space.

According to this invention there is provided a lockable barrier, said lockable barrier comprising a support adapted to be firmly mounted in position in or on the ground, there being a further member pivotally mounted on the support and movable between a substantially horizontal position and a substantially vertical position, the further member being provided with lockable means which engage the support when the said member is in said substantially vertical position to retain the member in that position.

Preferably the support comprises a base plate adapted to be mounted in or on the ground, and means defining a bush or bearing, the bush or bearing receiving part of said member to enable the member to pivot about a substantially horizontal axis defined by the bush or bearing.

Conveniently the support comprises an element defining an aperture, said aperture being the portion of the support adapted to be engaged by the lockable means provided on said member.

Advantageously the lockable means are actuated by means of a manually operable handle, key-operated means being provided to lock the lockable means.

Preferably said member comprises a horizontal portion which is rotatably connected to the support for rotation about a substantially horizontal axis, the horizontal portion supporting two substantially parallel arm portions which are interconnected by a transverse connecting portion to define a peripheral frame for the member, a housing being mounted on the frame and containing said lockable means.

Conveniently a manually operable handle is mounted on the housing9 the handle being lockable by means of a key-actuated locking mechanism, the handle actuating a locking mechanism incorporating a locking element which can be driven into and out of engagement with the support selectively to lock the said member in a substantially vertical position.

In order that the invention may be more readily understood, and so that further features thereof may be appreciated, the invention will now be described, by way of example, with reference to the accompanying drawings in which: FIGURE 1 is a front perspective view of a lockable barrier in accordance with the invention, FIGURE 2 is a rear view of the barrier, with parts thereof cut away on the line 2-2 of Figure 3, and Figure 3 is a vertical sectional view, taken on line 3-3 of Figure 2, FIGURE 3 also showing the barrier in its alternative position in phantom.

Referring to the drawings a barrier in accordance with the invention comprises on a support structure comprising a base plate 1 adapted to be firmly mounted in position. The base plate 1 may be provided with apertures to enable the base plate to be bolted or otherwise secured to the surface of a car park or the like, or may be adapted to be partially embedded in the surface of the car park or the like. The base plate 1 has secured to it an arched shaped metal element 2, this element being provided, at its apex 3, with an aperture 4, the purpose of which will be described hereinafter.

A transverse square sectioned tube 5 extends, between the two sides of the arch, resting on the upper surface of the support plate 1, and a horizontally extending tubular bush or bearing 6 rests on top of the tube 5.

Various webs 7 extend from the bust or bearing 6 to the inner surface of the curved part of the arch 2.

A member 8 in the form of a frame is pivotally mounted on the support. The member 8 has a lower horizontal tube 9 which extends through the tubular bush or bearing 6, so that the tube may rotate relatively freely about the axis of the bush or bearing 6. Mounted on the tube 9, is a further part 10 of the frame, this part of the frame defining two substantially parallel tubular portions 11, 12, interconnected by curved tubular portion 13. The free ends of the tubular portions 11, 12 are secured to the ends of the horizontal tube 9.

A transverse plate 14 extends between the two tubular portions 11, 12 adjacent the arch 2, and a hollow housing 16 extends between the plate 14 and the curved tubular portion 13.

A rotatable handle 17 is mounted on a front face of the housing 16, the handle 17 being provided with a lock 18, so that the handle may be locked to prevent an authorised rotatation thereof. As can be seen from Figure 2, the handle is connected to a drive lever 19, one end of the drive lever 19 being connected to a locking element 20 which extends downwardly, within the housing 16, through an aperture 21 formed in the plate 14, and through the aperture 4 formed in the arch 2. Thus, with the handle in position illustrated in Figure 2 the frame 8 is locked in a vertical position and can thus prevent unauthorised entry to a car parking space or the like. The locking element engages the aperture 4 at a position which is significantly spaced from the axis of rotation of said frame. When the key operated handle 17 is unlocked and rotated, the lever 19 moves to the position shown in phantom (19a), shown in Figure 2, thus lifting the locking element to the position shown in phantom (20a) in Figure 2, thus withdrawing the lower end of the locking lever from the aperture 4 formed in the apex 3 of the arch 2. The frame 8 is then able to rotate to the lowered position 22 illustrated in Figure 3.

The barrier in accordance with the invention is sturdy and strong, but is straightforward to manufacture.

Claims

CLAIMS:

1. A lockable barrier, said lockable barrier comprising a support adapted to be firmly mounted in position in or on the ground, there being a further member pivotally mounted on the support and movable between a substantially horizontal position and a substantially vertical position, the further member being provided with lockable means which engage the support when the said member is in said substantially vertical position to retain the member in that position.

2. A barrier according to claim 1 wherein the support comprises a base plate adapted to be mounted in or on the ground, and means defining a bush or bearing, the bush or bearing receiving part of said member to enable the member to pivot about a substantially horizontal axis defined by the bush or bearing.

3. A barrier according to claim 1 or claim 2 wherein the support comprises an element defining an aperture, said aperture being the portion of the support adapted to be engaged by the lockable means provided on said member.

A A barrier according to any one of the preceding claims wherein the lockable means are actuated by means of a manually operable handle, key-operated means being provided to lock the lockable means.

5. A barrier according to any one of the preceding claims wherein said member comprises a horizontal portion which is rotatably connected to the support for rotation about a substantially horizontal axis, the horizontal portion supporting two substantially parallel arm portions which are interconnected by a transverse connecting portion to define a peripheral frame for the member, a housing being mounted on the frame and containing said lockable means.

6. A barrier according to claim 5 wherein a manually operable handle is mounted on the housing, the handle being lockable by means of a key-actuated locking mechanism, the handle actuating a locking mechanism incorporating a locking element which can be driven into and out of engagement with the support selectively to lock the said member in a substantially vertical position.

7. A barrier substantially as herein described with reference to and as shown in the accompanying drawings.
