Abstract
A barrier device (1) comprises a housing (2) of channel section which accommodates at least one post (10). Each post (10) is considered as having a proximal end (11) and a distaiend (12). Support means such as roller bearings (17, 17') are provided for supporting the post (10) in the housing (2) in an inclined position with its distal end (12) raised with respect to the proximal end (11). An actuator 30 provides a displacing means operable for effecting displacement of the post (10) at its proximal end (11) along the channel (4) and towards the support means 17, 17'). This is effective to raise the distal end (12) of the post (10) from an inoperative position in which it is accommodated in the channel (4) to an operative position in which it projects therefrom and this may obstruct passage of vehicles. Several similar posts may be included in the housing with a linkage between them for raising all the posts simultaneously. <IMAGE>
Description
VEHICLE BARRIER
The present invention concerns a barrier device for restricting access of vehicles to a passageway, such as a road, particularly at or near an entrance or exit from a building, for example.
There is often a need to selectively restrict access of unauthorised vehicles to areas, particularly for security purposes. In this respect, various types of barrier devices are presently available. Generally, there is also a requirement that the barrier devices be readily removable or dismantleable to permit access for authorised vehicles.
Some example barrier devices presently in use include a post which can be telescopically or pivotally raised from an inoperative position to an operative position in which it presents an obstruction to vehicles. The post is typically retained in the operative position by use of a locking means such as padlock.
Various problems arise with such barrier devices.
Often, even when in the inoperative position, in which the post lies down on the roadway, the barrier still causes an obstruction. Also, if protection of a wide or otherwise large area is required, it is time consuming to raise several such posts independently.
The present invention recognises and seeks to alleviate at least some of the aforementioned problems.
In a broad aspect the invention concerns a barrier including one or more posts which require both translational and pivotal displacement from their inoperative to their operative position.
Accordingly, with this aim in mind the present invention provides a barrier device, the device comprising a housing of channel section, at least one post located in the housing, said post having a proximal end and a distal end, support means for supporting the post in the housing in an inclined position with its distal end raised with respect to the proximal end, and displacing means operable for effecting displacement of the post at its proximal end along the channel and towards the support means so as to raise the distal end of the post from an inoperative position in which it is accommodated in the housing channel to an operative position in which it projects therefrom.
Preferably the barrier device includes at least two posts, suitably arranged so that they may be raised and lowered substantially simultaneously.
Conveniently the displacing means for the barrier device are operable to displace the proximal end of the post along the axis of the channel towards the support means. Preferably the proximal end of the post is chamfered or rounded to assist in swinging the distal end of the post upwardly, above the proximal end, as the post rides over the support means. Suitably the barrier has means for providing a cross bar when the barrier is in the operative position, so as to further obstruct passage of verticals. Typically a cross bar is associated with the distal end of a post and, preferably, pivotally secured to the posts, at or near the distal end, so as to be capable of extending generally transverse to the post when the barrier is in the operative position.
Preferably a surface of the post, suitably the underside, is arranged to rest on the support means when the post is in an inoperative position. In preferred embodiments such a surface of the post is provided with a shoulder for resting on the support means when the post is in an inoperative position.
Most preferably a shoulder is also provided for accommodating or resting on the support means when the post is in an operative position. In preferred embodiments the post is provided with an undulating surface between two or more parts of the post, which parts are arranged for resting on the support means when the post is in its operative or inoperative positions, such as shoulders as aforesaid, to assist in swinging the distal end of the post into a generally upright position.
Suitably, securing means are also provided for securing the post in its operative position so as to inhibit retraction of the post into the housing. In preferred embodiments the displacing means for effecting displacement of the post also serve a8 a securing means for securing it in its operative position. Preferred such displacing and securing means comprise an actuator (possibly a screwed drive) operative to act on the post at or near its proximal end so as to displace the proximal end of the post in a direction towards the support means. When in an extended position the actuator may act as a securing means by inhibiting pivotal and/or translational displacement of the proximal end of the post in a direction away from the support means. Preferably any such actuator is pivotally secured to the post at or near the proximal end of the post.Suitable actuators are electrically, hydraulically or manually operable.
Preferably the actuator is operable from a remote location. Preferably the housing of the barrier device is adapted to accommodate any required power source for the actuator.
In preferred embodiments, the support means for supporting the post comprise one or more bearings.
Preferably, the support means are roller bearings, suitably arranged to be rotatable about an axis transverse to the channel of the housing. Any such bearing is suitably arranged so that it may support the post in an inclined position in which the distal end of the post is raised with respect to the proximal end.
Preferably the post is provided with ramp surfaces on its underside arranged to co-operate with one or more bearings upon displacement of the post so as to present the distal end of the post generally upright when in its operative position. In particularly preferred embodiments a post has associated therewith two or more opposed bearings, arranged spaced apart so as to define a path for displacement of the post between them.
In preferred embodiments the housing has a closure for closing the channel and shielding the post when in its inoperative position. Preferred embodiments may include a closure associated with the distal end of the post and arranged to present a cross bar for the barrier when the post is in its operative position.
Preferably, the housing of the device is adapted for flush mounting with the surface of the passageway to be obstructed, such as a roadway. In this respect, it is preferable that the housing includes a closure arranged so that, in use, the closure may be mounted flush with the passageway.
In particularly preferred embodiments the barrier includes at least two posts arranged spaced apart within the channel, although the appropriate number of posts may vary to suit the extent of the area to be obstructed. Preferably, a linkage is provided between such respective posts. Preferably any such linkage is arranged so that displacement of one post is effective to actuate corresponding displacement of the or each respective post.
Embodiments of the present invention, will now be described further, by way of example, with reference to the accompanying drawings in which:
Figs. la and 1b are sectional views of an example barrier device, Fig. la shows the barrier in an open or operative position and Fig. 1b in a closed or inoperative position;
Figs. 2a and 2b are cross-sectional views of the device of Figs. la and lb; Figs. 3a and 3b are perspective views of the barrier device; and
Figs. 4a and 4b are perspective views of the barrier device when mounted in a roadway.
Turning firstly to Fig. 1, this shows a barrier device indicated generally at 1. Fig. 1 shows the device 1 in an operative or "closed" position and Fig.
1b illustrates an inoperative or "closed" position. The device includes a housing 2 which is generally of box section and defines an internal channel 4. The housing 2 also has a removable closure 8 having an internal channel 8'.
Posts 10 and 20 are located in channel 4 in the housing 2. The posts may be constructed from any strong material, such as steel, for example. The posts 10, 20 have rounded proximal ends 11, 21 respectively, both located in the base of channel 4. The distal ends of the posts 10, 20 are designated 12, 22 respectively.
The distal ends of the posts 10, 20 are pivotally connected at 13, 23 to the interior of the closure 8 in channel 8'.
The posts 10, 20 are supported in the housing 2 by respective roller bearings 17, 27 and between opposing bearings 17', 27' respectively. The bearings are arranged so as to be rotatable about axes transverse to the channel 4. The undersides 14, 24 of the posts rest on the respective bearings 17, 27. Each post 10, 20 is provided with a shoulder 16, 26 at or near its distal end for resting on the bearings when in the inoperative position. The posts also have shoulders 16' 26' intermediate their distal and proximal ends for resting on the bearings in the operative position. Each post 10, 20 is also provided with ramp surface formations 15, 25 between shoulders 16, 16' and 26, 26' respectively. The ramp surface formations 15, 25 cooperate with roller bearings 17, 27 to guide displacement of the posts 10, 20.
An actuator 30 is located in the housing 2, and is arranged with its free end pivotally connected to the proximal end 11 of post 10 at 18. The actuator is arranged to extend and retract along the axis A of the channel 4. A power source 40 for the actuator 30 is accommodated in the housing.
An interconnecting linkage indicated as item 42 is provided between posts 10, 20, and arranged below the roller bearings 17 and 27.
In use, the housing 2 is mounted in a roadway (or other passageway) such as illustrated in Figs. 4a and 4b and arranged so that closure 8 is generally flush with the floor level when the barrier is in a closed position. Fig. 1b and 4b show the first, inoperative position of the barrier. In this position, both posts 10, 20 are supported at shoulders 16, 26 at their distal ends 12, 22 by roller bearings 17, 27 respectively. The actuator 30 is withdrawn into its inoperative position. The closure 8 is located on the housing 2.
To bring the barrier into its operative position, the actuator 30 is actuated to drive displacement of the proximal end 11 of post 10 along axis A towards bearing 17. This disengages shoulder 16 from the bearing 17 and drives the ramp surface formations 15 of post 10 over bearing 17 until the bearing 17 engages in shoulder 16'. The post 10 swings upwardly about the curved proximal end 11 so that the distal end 12 of the post is presented in a generally upright position, as indicated in Figs. la and 4a.
The interconnecting linkage 42 actuates corresponding displacement of the second post 20 so that its distal end 22 is also generally upright. In this operative position the closure 8 is presented above the level of the roadway so as to act as a cross bar to obstruct passage of vehicles. The actuator 30, when in operation, also serves to retain the post 10 in its operative position.
When the barrier device 1 is no longer required, the actuator 30 may be released, allowing posts 10 and 20 to be lowered into the housing 2, drawing the closure 8 downwardly to close the housing 2 and to present the closure 8 flush with the roadway.
It will be appreciated that various modifications may be made to the illustrated embodiment. For example, the barrier device may include any number of posts, which may be the same or different, and any such posts may be independently operable. Also, a post may take a variety of forms although provision of an undulating underside is of assistance in presenting the post generally upright in the operative position. The barrier device may be adapted for mounting in the interior or exterior of a building, as desired.
