The present invention relates to a gate. More specifically, the present invention relates to a gate having at least one arm, wherein the at least one arm is configured to extend and retract. When the at least one arm is substantially extended, the at least one arm substantially prevents access through the gate. When the at least one arm is substantially retracted, the at least one arm no longer substantially prevents access through the gate.

A door assembly for an animal enclosure includes a door frame and a door each having a plurality of interconnected horizontal and vertical wires. The door frame defines an opening for an animal to pass therethrough, and the door is slidably coupled to the door frame such that it moves between an open position and a closed position relative to the door frame to allow egress and ingress through the opening. A catch member is coupled to the door frame. A latch includes a base member, a bolt, and a lever portion. A first vertical wire and a second vertical wire of the door are spaced from one another such that the first vertical wire is at a first end of the door and the second vertical wire is at a second end of the door. In the closed position, the bolt is coupled to the first vertical wire.

A door body includes a door main body, an upper guided portion provided to an upper portion of the door main body, and a lower guided portion provided to a lower portion of the door main body. A guide member includes an upper guide portion, a lower guide portion, and a restricting portion. The upper guide portion supports the upper guided portion from below while restricting movement of the upper guided portion along the fore and aft direction. The lower guide portion supports the lower guided portion from below while restricting movement of the lower guided portion along the fore and aft direction. The upper guided portion is moved upwardly away from the upper guide portion in the expanded support state. The restricting portion restricts movement of the door main body in the first direction in the expanded support state, and restricts movement of the door main body in the second direction in the expanded support state.

The present invention is directed to a gate system capable of recognizing the shape of an object, for example a car, and generating a passage opening which is adapted to the shape of the object.

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 opener for simultaneously operating a pair of opposed sliding gates. The gate opener includes a pair of identical pulley assemblies one each affixed to the ground adjacent to a either gate and oriented a hundred eighty degrees to each other. A first cable is affixed to a lateral edge of a first gate, passes through a series of pulleys and is affixed to a medial edge of a second gate. A second cable is affixed to a lateral edge of a second gate, passes through a series of pulleys and is affixed to a medial edge of the first gate.

The present gate handle includes a push button that is pushed before the gate handle is slid from a closed position to an open position on top of a support member. The support member includes a resilient button that extends into the gate handle and is pushable out of the gate handle by the push button. The support member further includes side slots that are engaged by side slides extending from the handle.

A gate system includes a plurality of gate portions, including at least a first gate portion and a second gate portion. A motor includes a drive shaft and a first pinion secured to the drive shaft. A first gate portion includes a first rack configured to be driven by the first pinion. The first gate portion further includes a second pinion rotatably secured to a wheel of the first gate portion. The second gate portion includes a second rack configured to be driven by the second pinion. The second rack may be selectively coupled with or uncoupled from the second pinion by way of a clutch gear.

A linear gate drive assembly with a drive rail connectable to a gate panel. The drive rail has a first drive surface. A linear drive portion is coupled to the first drive surface and has teeth thereon with a first rolling tooth profile. The linear drive portion defines a toothed second drive surface. Dive motors are pivotally coupled to a support structure. A first drive wheel is attached to one drive motor and engages the first drive surface to impart an axial drive force on the drive rail. A second drive wheel is attached to another drive motor and engages the second drive surface. The second drive wheel has second teeth that mate with the first teeth and that define a second rolling tooth profile that substantially corresponds to the first rolling tooth profile. Rotation of the second drive wheel imparts axial and normal forces via a rolling teeth interface the mating teeth for moving the drive rail and the gate panel.

A ground assembly for movable member includes an electrical ground connection that does not interfere with movement and operation of the movable member. The movable member can be a sliding member (e.g., sliding barrier, gate or closure member). The ground assembly includes an electrical connector fixed to the movable member and moves along a length of a fixed grounding member while maintaining contact with the electrical grounding member to provide continuous grounding connection during movement of the movable member. The fixed electrical grounding member can be oriented with a longitudinal length parallel to direction of movement of the movable member where the electrical connector of the movable member moves along the electrical grounding member. Alternatively, the electrical connector is fixed to the grounding member and the movable member includes a surface that slides in contact with the electrical connector by movement of the movable member relative to the grounding member.
