A retractable fence assembly includes a plurality of lifting units. Each of the lifting units is sunk into a support surface. Each of the lifting units is selectively positioned in a deployed position to extend upwardly from the support surface. Each of the lifting units is selectively positioned in a stored position to be stored beneath the support surface. A fencing unit is operationally coupled to each of the lifting units. Each of the lifting units selectively positions the fencing unit in the deployed position to surround an area. Each of the lifting units selectively positions the fencing unit in the stored position. Thus, the fencing unit is positioned in a trench in the support surface thereby facilitating the fencing unit to be concealed.

Example impactable gate systems disclosed herein include a track to be coupled to a base post, a drive strip slidable along the track, a rail including a tube, the rail to move with the drive strip relative to the track between an opened position and a closed position, and a bracket to be disposed within the track, the bracket to couple the rail to the drive strip, the bracket to be disposed within the base post when the rail is in the closed position.

A safety barrier assembly is provided for a parking garage is positioned in proximity to an opening for a VRC and includes a horizontal AGV safety beam and upper and lower pedestrian barriers having horizontal railings and vertical legs. The vertical legs are slidable within openings at opposite ends of the AGV safety beam. The vertical legs of the upper pedestrian barrier are longer than those of the lower pedestrian barrier. The AGV safety beam can be moved vertically between a lower position where the AGV safety beam is substantially adjacent a floor of the parking garage and an upper position where the AGV safety beam is elevated from the floor. The horizontal railings of the pedestrian barriers are parallel to and spaced above the AGV safety beam in the lower position. However, the horizontal railings abut the AGV safety beam in the upper position.

The present invention relates to a parking barrier having an advertising function, and the present invention relates to a parking barrier in which vertical panels printed with an advertisement are arranged and provided so as to be supported by a cross bar, thereby having an advertising function. The parking barrier having an advertising function according to the present invention comprises; a driving unit; an upper cross bar provided so as to be rotatable by the driving unit, thereby controlling vehicles; and a plurality of vertical panels provided at the upper cross bar such that upper ends thereof are rotatable, thereby maintaining a vertical state by the weight thereof, wherein a rotating shaft and the revolving shaft so as to be engaged with each other such that the vertical panels revolve on the revolving shaft when the upper cross bar rotates so as to stand upright.

There is provided a barrier and a method of opening and closing a barrier. The barrier including a first arm moveable about a first support, a second arm moveable about a second support and at least one coupling. The first and second supports are spaced across an opening and the barrier is arranged between an open and closed position, such that in the closed position, the arms are arranged in combination to traverse the opening. The barrier is further arranged in a locked position, such that the coupling is slidably coupled to the first and second arms. The barrier improves the safety of loading bay areas in order to allow the efficient transfer of goods on freight transportation vehicles.

A safety gate apparatus is provided which couples as a cost efficient and reliable gate for preventing falls and injury as well as a gate that can easily be opened by existing equipment such as a fork lift. The invention comprises a vertical sliding gate configured to move in a path of motion having at least a closed position and an open position. The vertical sliding gate remains in a closed, default position by an applied counter force created by one more elastic means. The sliding gate slides down to an open position by a downward force created by a fork lift or other machinery. The gate will automatically return to the default position when the downward force is removed.

A positioning device for fence supplemented with pet guardrail comprises: an upper embedding slot and a lower embedding slot having face-to-face openings and extending axially being respectively formed on an opposite outside of the upper crossbar and the lower crossbar of the pet guardrail, for embedding the upper and lower ends of the straight rod and fixing the straight rod via the positioning peg from the inner side of the upper crossbar and the lower crossbar to avoid the exposure of the positioning peg and omitting the installation of the front cover plate on the front side of the upper crossbar and the lower crossbar, and moreover, the side cover installed and covered on the left and right ends of the upper crossbar and the side cover facing the end of side pole of the existing fence being an circular arc surface, thereby meeting the installation inclination angle of the existing fence. The configuration of the circular arc surface enables the side cover to maintain attached with the side pole.

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.
