A gate apparatus having an automatically returning gate, an upper latch operated by an upper button, and a lower latch operated by an upper finger handle. Each of the latches must be opened to open the gate. The gate returns without the aid of a spring to a position close to the closed position or to the closed position by the structure of a pivot or hinge connection between the gate and the frame of the gate. Gate tubes are rectangular in section for their entire length. Wood panels are included in the gate and excluded from other portions of the gate apparatus to make the gate stand out to the user seeking to open the gate.

A barrier that includes four structurally different corner connections for fixing a gate frame of the barrier to and between opposing vertical surfaces. A first connection includes a headed straight pin engaging a pivot hook and socket, a second connection includes a headed straight pin engaging a socket, a third connection includes headless bent pin engaging a socket and a limiter, and a fourth connection includes a headless bent pin engaging a socket.

A gate system and related control systems and methods include a frame assembly and a tracking assembly coupled to the frame assembly. A door is in mechanical communication with the frame assembly. Related methods for operating a gate of a gate system, where the gate is set to manual mode to manually open or close the gate. Additionally, control systems include a fail-safe programmable logic controller (PLC) circuit for controlling the gate for opening and closing a gate that employs redundant fail-safe features. The control system includes a safety PLC circuit having a PLC including a first input terminal and a second input terminal, and a light curtain switch electrically coupled to the first and second input terminals.

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.

The present invention relates to inflatable bladder actuated water control gates for control of open channels such as rivers and canals and for control of dam spillways without the need for intermediate piers. The air bladder and hinge flap wedge clamping system includes hinged engagement of the upstream edge of the clamps to the foundation so as to prevent the application of bending and shear loads to the anchor bolts. The resulting configuration facilitates the use of high strength alloy steel anchor bolts in a corrosion protected environment and also prevents tensile loading of the concrete foundation and associated cracking of the concrete foundation.

A lock includes a pair of spaced apart parallel bolts connected by a plate extending between the bolts. A slot, formed in a hinged structure, such as a gate, extends from a free edge of the structure (an edge opposite a hinged edge) to an end point at a determined distance from the free edge. The plate is received in the slot. Each bolt is located on an opposite side of the hinged structure, when the plate is received in the slot. The slot defines a range of sliding motion of the plate and bolts.

A hinge has a first component that pivotally supports a second component of the hinge. The first hinge component carries an energy harvesting switch having a movable operator such as a spring-projected plunger that is positioned to be depressed or otherwise moved by the second hinge component in response to relative pivotal movement of the first and second hinge components. If a gate is fastened to the second hinge component, at least some of the weight of the gate is transferred from the second hinge component to the first hinge component. When the gate is pivoted away from a closed orientation toward an open orientation, the second hinge component moves the operator of the energy harvesting switch thereby causing the energy harvesting switch to emit a radio frequency signal.

A passage barrier has guide elements, the first guide element and the second guide element cooperate such that they define a gate region, through which a person passes from an entrance region into a passage region. At least one guide element includes a vertically running profile, on which a locking apparatus is arranged. The locking apparatus has a torque transmission toothing, which engages into a complementary torque reception toothing of the hollow shaft, wherein a circular stop disc is disposed, which has a toothing engagement, which is engaged with the torque transmission toothing. The stop disc has on its stop disc circumferential surface a stop lug, which protrudes radially from the stop disc circumferential surface, and cooperates with a stop element arranged on the vertically running profile such that a rotation of the stop disc is delimited by the stopping of the stop lug against the stop element.

A gate opening and closing assembly includes a mount that is coupled to a vertical member of a gate that is extendable across an entry way. A drive unit is coupled to the mount and the drive unit is actuated to rotate in a first direction or a second direction. A wheel is rotatably coupled to the drive unit to roll along the ground. The wheel is rotated in an opening direction when the drive unit rotates in the first direction to urge the gate into an open position thereby facilitating a vehicle to drive through the entry way. The wheel is rotated in a closing direction when the drive unit rotates in the second direction to urge the gate into a closed position thereby inhibiting the vehicle from driving through the entry way. A remote control is in wireless electrical communication with the drive unit. The remote control turns the drive unit on and off to open and close the gate.

A wing/swing turnstile gate, installed at controlled entrances or exits, comprising at least: a frame; a flap; the frame comprises at least a control unit and an actuating means. The control unit is in communication with the actuating means such that the control unit is able to operate the actuating means. The flap is fixed to the actuating means of said frame such that the flap is operable, from a close position to an open position and/or vice versa when a user is present within its zone of detection, by said control unit via the actuating means. The flap is equipped with a sensing device, in communication with the control unit, apt to regulate the behavior of the flap, and/or send information of a user to the control unit to be processed.
