Abstract

Device prohibiting access of alien vehicles to given zones, while allowing recognized, identified and authorized vehicles to enter, consisting of at least one re-usable modular element with instantaneous positioning which requires no specific installation, comprising an access-control barrier (13) activated by the help of the lever (14) of a release mechanism (9) (11) (17) (18), operable by a lever (11) and by a stop-barrier (2), which is released by the action of a skid (16) on a skid (9) pushing a bolt (7), the whole being incorporated in a frame (1).

Claims

1. Modular anti-intrusion barrier, comprising a single body which is, at one and the same time, an access-control barrier and a stop-barrier, linked to each other by a release mechanism, which activates the stop-barrier allowing, once loaded, an instantaneous, extremely high-powered action, and by the fact that it is placed on the ground

wherein the loading of the modular anti-intrusion barrier is assured by the lowering of the stop-barrier, which tightens the spring, and by the fact that the stop-barrier is maintained flush by a bolt, the movement of the control barrier into a vertical position being obtained by activating a manoeuvering lever operatively connected only with said control barrier.

2. A modular anti-intrusion barrier for preventing unauthorized entry of a vehicle, comprising:

a frame;

a control barrier means movable from a first horizontal position through a second vertical position;

means for preventing vehicle entry movable from a first deactivated position to a second activated position;

means operatively connecting said control barrier means to said preventing means for actuating said preventing means;

said actuating means being operable in response to contact energy of a vehicle against said control barrier means.

3. The modular anti-intrusion barrier according to claim 2, further comprising means for moving said control barrier means from said first position through said second position.

4. The modular anti-intrusion barrier according to claim 3, further comprising means for retaining said control barrier means in said first position.

5. The modular anti-intrusion barrier according to claim 3, further comprising means for retaining said preventing means in said first position.

6. The modular anti-intrusion barrier for preventing unauthorized entry of a vehicle, comprising:

a frame;

a control barrier means movable from a first horizontal position through a second vertical position;

means for preventing vehicle entry movable from a first deactivated position to a second activated position;

means operatively connecting said control barrier means to said preventing means for actuating said preventing means;

said actuating means being operable in response to contact energy of a vehicle against said control barrier means;

said control barrier means being rotatable about a horizontal axis and including a first skid member eccentrically mounted about said horizontal axis and slidable on said frame; and

said actuating means including a second skid member rotatable about a second horizontal axis from a first position, in which the second skid member is abuttable by the first skid member, and a second position thereby defining a clearance between said second skid member and said first skid member.

7. The modular anti-intrusion barrier according to claim 6, wherein said actuating means further comprises means for moving said second skid member from said first position to said second position.

8. The modular anti-intrusion barrier according to claim 6, wherein:

said actuating means includes a horizontally movable pusher member;

a lever means rotatable upon contact with said pusher member; and

means for retaining said preventing means, said retaining means being moveable by said pusher member through said lever member.

9. The modular anti-intrusion barrier according to claim 7, further comprising means for urging said preventing means from said first position to said second position.

10. The modular anti-intrusion barrier according to claim 8, further comprising means for limiting the movement of said preventing means.
