A retract gate has an upper roller assembly, a lower roller assembly, an axial tube, a holding pole, and a screen body. The upper roller assembly has a rolling mechanism and a controlling mechanism. The controlling mechanism has a switch and an engaging component, the engaging component selectively sticking the differential crown gear. Two ends of the axial tube are connected with the upper roller assembly and the lower roller assembly. Two ends of the screen body are securely fixed on the holding pole and the axial tube. When the upper roller assembly is turned on, the rolling mechanism is released; when the upper roller assembly is turned off, the rolling mechanism can memorize the maximum length of the screen body and make the screen body not able to be unrolled further. Consequently, the retract gate can restrict babies and pets within a safe area.

A double door gate apparatus having a frame, a main gate and a secondary gate, where the apparatus includes the unique features of a) a latch apparatus between uppermost framework members of the main gate and secondary gate, b) the latch apparatus being weighted to return to a normally closed position, c) each of the main gate and secondary gates having an inverted U-shaped piece engaging the bottommost horizontal member such that each of the main and secondary gates need to be lifted prior to being opened and prior to being closed, and d) a pair of hand wheels on a common shaft that work together to space the double door gate apparatus a desired distance from a vertical surface such as a wall.

A swing gate mechanism to swing open an overhead lift gate system includes an overhead swing gate. The overhead swing gate has a pivot side and a catch side. A first gate power arm is configured to move along a first overhead guide track on a first side of the overhead lift gate system. A second gate power arm is configured to move along a second overhead guide track on a second side of the overhead lift gate system. At least one hinge is connected between the pivot side of the overhead swing gate and the first gate power arm. The at least one hinge is configured to allow the overhead swing gate to swing open by rotating about the first gate power arm.

A show-ride attraction includes a moving pathway configured to transport a guest toward a barrier, and a gate positioned across the moving pathway upstream of the barrier relative to a direction of travel of the moving pathway, wherein the gate is configured to transition between a first position and a second position in response to the guest engaging with the gate. The ride-show attraction further includes one or more sensors configured to detect transitioning of the gate from the first position to the second position, and a controller configured to control the moving pathway in response to an indication from the one or more sensors that the gate is transitioning and/or has transitioned to the second position.

A vehicle barrier gate system which is positioned above a roadway through which vehicles pass. Some of the various embodiments of the present disclosure include a gate comprised of an arm and barrier which is adjustable between a raised position in which a vehicle may pass and a lowered position in which a vehicle is prevented from passing. The gate may be movably connected to a ceiling or an overhead support structure positioned above the roadway. Various types of actuators may be utilized to adjust the gate along a linear and/or angular path between the raised and lowered positions. A control unit may be in communication with one or more sensors and/or an authorization system to control the actuator. The gate may include a breakaway mechanism which allows the gate to be manually raised or lowered in the event of actuator failure or a vehicle ramming through the gate.

A movable modular vehicle barrier (10) formed from at least two modular units (12). Each modular unit is foldable and comprising: a base bar (14), a reclining bar (16) hingedly connected to the base bar, a horizontal reclining bar (38) hingedly connected to the base bar, and a vertical reclining bar (42) hingedly connected to the reclining bar. In a folded position of the modular unit the base bar, the reclining bar, the horizontal reclining bar and the vertical reclining bar are substantially parallel to each other. In an operative position of the modular unit, the reclining bar forms with the base bar an internal angle that is not smaller than ninety degrees, the horizontal reclining bar is perpendicular to two adjacent base bars, and the vertical reclining bar is perpendicular to two adjacent reclining bars. The barrier includes a moving system for enabling manual movement of the barrier.

A dock gate barrier system includes: a barrier with first and second ends with a central axis extending therebetween, and a coupling defining a passage; and a support member, from which extends a hitch pin, which extends along a longitudinal axis, and can enter and extend into the coupling passage. The hitch pin and the passage are configured such that: in a first configuration, the hitch pin can enter into/withdraw from, the passage; and in a second configuration, in response to a load being applied to the barrier causing it to bend, the hitch pin is engaged with the coupling to thereby lock the coupling relative to the hitch pin and thereby lock the barrier member to the first support member.

In a method for operating a vehicle barrier (1) having a barrier column (2), a barrier arm (4) and a drive mechanism for pivoting the barrier arm (4) between a blocking position and an open position, a camera (7) is used for vehicle recognition, for the license plate recognition, for recognizing a following vehicle and for monitoring for vandalism, and the images thereof are evaluated by an electronic evaluation logic that is coupled to control of the vehicle barrier (1).
