An electric gate system adapted to close an open space. The electric gate system includes a support disposed at an edge of the open space, and a first plurality of gate segments. Each of the first plurality of gate segments has a closed operative orientation and an open operative orientation, where the closed operative orientation and the open operative orientation are in a single plane and are rotationally offset from one another. A gate opening assembly is attached to the support. At least one electric motor is functionally associated with each of a second plurality of gate segments, the second plurality of gate segments being a subset of the first plurality of gate segments. During operation thereof, the at least one electric motor causes simultaneous rotational motion of all gate segments in the second plurality of gate segments.

A traffic gate apparatus comprises an upstanding pedestal. A first elongate arm is also provided having a proximal end and a distal end, with the proximal end of the first elongate arm being pivotally connected to the pedestal at a first pivot axis. A second elongate arm has a proximal end and a distal end, with the proximal end of the lower elongate arm being pivotally connected to the pedestal at a second pivot axis. The second pivot axis is below the first pivot axis such that the first and second elongate arms are movable between a lowered position, in which the first and second elongate arms are generally horizontal and parallel with the first elongate arm being above said second elongate arm, and a raised position. The first and second elongate arms each have an adjustment mechanism such that a length thereof can be varied.

The gate has an exchangeable span that is fixed to the load bearing beam and is connected with pulley bearings and rope-slings to the system of adjustable counterweights. The drive system is fitted with an electric drive with a worm-wheel mounted to the load bearing beam that travels vertically along the worm. The beam, span and the drive travel on adjustable guiderails inside a reinforced concrete pit in the direction opposite to that of counterweights. The load bearing beam is fitted with rollers and retaining rollers mounted to the cover. Emergency (manual) operation of the gate is possible by turning a crank handle connected with the worm, having released the lock that prevents the worm from rotating on its axis.

An electric strand gate has at least one electric strand thereacross. The gate comprises an actuator which moves the electric strand up along a hoisting rail from a closed position to an open position, thereby providing clearance thereunderneath for passage of livestock, vehicles and or the like through the gate. The gate may have shuttles travelling along the hoisting rail, each of which is connected to a respective electric strand. The rail and shuttles may be configured so that electric strands are closer together when in the open position, thereby maximising clearance thereunderneath whilst moving apart in the closed position, so as to maintain the full height of the electric fence. The shuttles and the rail may be further configured so that the electric strands are electrically disconnected in the open position.

A mezzanine gate assembly designed for installation along the edge of an elevated platform with a railing includes a central support assembly with two lateral sides. The assembly features a first side gate assembly pivotally mounted on the first lateral side, comprising lower and upper swing arms pivotally attached to the central support assembly and connected by a member. Similarly, a second side gate assembly is pivotally mounted on the second lateral side. Both gate assemblies can be rotated about a first axis between downward and elevated positions and about a second axis between forward and aft positions. This design allows for versatile movement and positioning of the gate assemblies to enhance safety and accessibility on elevated platforms with railings.

A room access control system including a base assembly positionable adjacent a door opening; an arm having a first end pivotally mounted with respect to the base assembly; wherein the arm is positionable in a first undeployed position where the arm is generally vertical and the second end of the arm points downwardly; wherein a fan assembly is attached to the arm, the fan assembly including a plurality of fan blades; wherein each of the fan blades is pivotally mounted to a pivot point on the arm; wherein when the arm is rotated into a second, generally horizontal deployed position, the plurality of fan blades extend beneath the arm in a fanned out pattern with the second end of a first fan blade of the plurality of fan blades attached to the arm, and a last fan blade of the plurality of fan blades positioned in a generally vertical position.

A room access control system including a base assembly positionable adjacent a door opening; an arm having a first end pivotally mounted with respect to the base assembly; wherein the arm is positionable in a first undeployed position where the arm is generally vertical and the second end of the arm points downwardly; wherein a fan assembly is attached to the arm, the fan assembly including a plurality of fan blades; wherein each of the fan blades is pivotally mounted to a pivot point on the arm; wherein when the arm is rotated into a second, generally horizontal deployed position, the plurality of fan blades extend beneath the arm in a fanned out pattern with the second end of a first fan blade of the plurality of fan blades attached to the arm, and a last fan blade of the plurality of fan blades positioned in a generally vertical position.

A door apparatus for closing an access opening and to a parking apparatus equipped therewith. The door apparatus has two vertically aligned guide rails and an inner and an outer door element which are each movably mounted in/on a vertically aligned inner or outer guide of the guide rails. In a closed position, the inner door element is arranged in a first region of the access opening which is situated lower than a second region in which the outer door element is arranged. In an open position, the inner and the outer door element are arranged in a third region of the access opening which is situated higher than the first and the second region. Furthermore, the door apparatus has a locking element and a coupling element.

A multi-layered film including a polyvinyl chloride (PVC)-based base layer containing a plasticizer and including a surface layer containing a UV stabilizer that is adhesively bonded to the base layer, wherein an acrylate-based PVC-free copolymer is used as a plasticizer in the base layer.

A room access control system including a base attachable to a wall or door jamb adjacent a door opening to a room, an arm having a first end pivotally mounted to the base and having a second end, illuminated warning indicia positioned on the arm, wherein the arm is positionable in a first position wherein the arm is in a generally vertical, undeployed position with the second end of the arm positioned above a floor located beneath the base and adjacent the door opening, and wherein the arm is pivotable from the first, generally vertical undeployed position, to a second generally horizontal, deployed position, where the arm extends across the door opening.
