Security enclosure and gate system

A security access gate comprising one rigid barrier on each side, each said barrier being retractable and adapted to mechanically latch to each other when fully closed, each said barrier having a separate support and drive posts supporting the driven end, comprising upper drive means which provide positive drive connections to an upper surface of said barrier through downward pressure on at least two laterally separated points and corresponding lower drive means which provide positive drive connections to a lower surface of said barrier and support that barrier on at least two laterally-separated points, said upper drive means and said lower drive means being driven by a common power source and connecting drive means to open and close the gate by retracting and advancing said barriers, further comprising remote switching means to operate latching means and said drive means to open or close said gate by simultaneously retracting or advancing each of said barriers.

A power-driven remotely-actuated security gate, comprising a rigid barrier formed of tubular metal stock, a latch post to receive and support the barrier at one end with an electrically activated mechanical latch and a support and drive post supporting the driven end of said barrier, comprising an electric drive motor connected by mechanical drive means with at least two upper and two lower drive rollers, said upper drive rollers exerting downward pressure on an upper surface of said barrier on at least two laterally-separated points and the corresponding lower rollers exerting upward pressure on said barrier on at least two laterally-separated points, with said upper drive rollers and lower drive rollers being driven at the same speed but in opposite directions to open and close said gate by retracting or advancing said barrier, further comprising remotely actuated switching means activated by radio or an electrical signal to activate said latch and said drive motor to commence a cycle of opening said gate, followed by a variable predetermined time delay at the subsequent closing of said gate.

A barrier structure section suitable for security fences, gates or the like, comprising at least two horizontal tubular members interconnected by a plurality of vertical tubular members to form said section, further comprising at least one reinforcing cable passing through at least one of said horizontal tubular members and at least on cable passing through said at least two horizontal members and at least a portion of said vertical tubular members in interwoven fashion, with means for latching or mechanically connecting each end of said barrier section and the corresponding ends of said cable to another such section or to a stationary object.
