Assembly for preventing the vehicle passage
First Claim
1. Assembly for preventing vehicle passage across an access road having an elongate open top excavated trench formed transversely thereacross, the assembly comprising:
- an elongate swing-gate sized to fit within at least a portion of the open top trench, the swing-gate having a first side, a second side as well as a upper side and a lower side;
a fixed support to be located at a first edge of the open top trench;
a movable support supporting the second side, the movable support having an upper end and a lower end;
where the first side of the swing-gate is mounted to the fixed support and the movable support supports the lower side of the swing-gate adjacent to the second side, and the lower end of the movable support stands on the bottom of the excavation; and
a flexible tensile member connected to the movable support, where the flexible tensile member is activated by an activating assembly, the activating assembly including a movable plate defining a slot therethrough and having a bottom surface and a carrier having a top surface, where at least one groove is formed on the top surface and the carrier defines an opening therein, and where the bottom surface of the moveable plate is slideably connected to the top surface of the carrier, the activating assembly further comprising at least one roller which cooperates with the slot of the movable plate and the groove of the carrier so that when the activating assembly activates the tensile member, the movable support no longer supports the second side of the swing-gate, allowing the swing-gate to fall into the excavation, preventing vehicle passage from both directions.

Abstract
The assembly of the mobile swing-gate is installed in the channel that is dug across the entire width of the road, and the sides of the excavation are reinforced by wall (5). The created recess is over-bridged by swing-gate (1). One side of swing-gate (1) is connected onto joint (2) that is fixed onto channel wall (5). The opposite side of swing-gate (1) is supported by support grate (3) that by its upper side leans against swing-gate (1) and by its lower side against the corner of wall (5). Steel rope (4) is attached at the upper side of the support grate. By pulling steel rope (4) the support grate (3) eludes bellow swing-gate (1) that remains without support at that side, rotates about joint (2) and falls into the channel, and in such a way a recess is opened in the road.
