A pre-assembled gate opener assembly is comprised of a gate and an anchor assembly having a platform. A plurality of track assemblies on the platform provide a track on which the gate may slide from a first position (closed) to a second position (open) and any position in between. A guidepost having a Shepherd's hook configuration guides the gate as the gate passes therethrough. A pair of rollers within the interior of the top of the guidepost makes continuous contact with each side of the top of the gate both while the gate is stationary and in motion. A gate opener controller contains the required electrical connections to fully the operate gate opener assembly. Subterrain anchor supports provide the necessary support for the gate opener assembly. An alternative embodiment accommodates nontraditional configured gates. Installation of the gate opener assembly is performed by do-it-yourselfers in minimal time.

A system may include a first module and a second module. The first module may include a first transceiver, the first module configured to transmit a request using the first transceiver. The second module may include an input connection for an obstruction sensor and a second transceiver configured to receive a request from the first transceiver. The second module may be configured to receive sensor information from the obstruction sensor and send a response to the first module based on the sensor information.

A breakaway gate assembly includes a hinge subassembly rotatably mounted to a vertical hinge post, and a gate subassembly removably mounted to the hinge subassembly. The gate subassembly includes a gate body and a plurality of standoff features coupled thereto. The hinge subassembly comprises a vertical mounting plate forming a plurality of apertures configured to receive and secure a respective plurality of standoff features. Each of the plurality of apertures comprises a wide portion for receiving a head portion of one of the standoff features, and a narrow portion below the wide portion for receiving a stem portion of a respective standoff feature to position a portion of the vertical mounting plate between the vertical mounting surface and the respective bearing surface. The hinge subassembly also comprises a plurality of hinge rings coupled to the first plate surface, the plurality of hinge rings rotatably disposed around the vertical hinge post.

A system for guiding and supporting a leaf of a platform-access door capable of moving relative to a fixed panel in a horizontal translational movement in a plane of the leaf between open and closed positions, includes a rail extending in a direction of the horizontal translational movement, a first set of rollers collaborating with the rail, for guiding and supporting it, with an axis of rotation perpendicular to the plane of the leaf and being made up of: a main roller in contact with a lower bearing surface of the rail; first and second secondary rollers which are offset from one another in at least a vertical direction and respectively in contact with the lower bearing surface and with an upper bearing surface of the rail and positioned some distance away from the main roller in the direction of a transition from the closed position into the open position.

An elevator car upper handrail apparatus, in which a connecting body is provided between respective ends of first and second side handrails on a landing side. The connecting body includes an opening/closing member which is rotatable between a closed position, in which a path for movement of a worker from a landing to a car upper surface is closed by the opening/closing member, and an open position, in which the path for movement is opened by the opening/closing member. The opening/closing member is configured to return automatically to the closed position. When the opening/closing member is in the closed position, the connecting body transmits an external force applied to one of the first and second side handrails in the width direction of a car to the other of the first and second side handrails.

A hinge apparatus that includes a stationary hinge portion, which includes a first bracket configured to be attached to a fixed surface, a first arm extending from the first bracket, and a second arm extending from the first bracket. The first and second brackets include axial holes with a hinge pin arranged therethrough. The hinge pin defines a rotation axis. The stationary hinge portion also includes a stop plate extending away from the first bracket and connected to the first arm. The hinge apparatus also includes a rotatable hinge portion, which includes a body arranged around the hinge pin between the first and second arms and a stop body extending from the body along the rotation axis. Ends of the stop body contact the stop plate to limit rotation of the body about the rotation axis. A second bracket configured to be attached to a movable body.

A hinge locking mechanism is provided for securing a gate, the mechanism comprising a locking component that is connectable to the gate and which is biased against a first plate that is connectable to a post about which the gate pivots, such that the locking component is secured to or within the first plate when the gate is in the closed position (preventing movement of the gate into the open position). Also provided is a gate having said hinge locking mechanism and a method of securing a gate using the mechanism.

A trolley assembly comprises a frame incorporating at least one tire encompassing a wheel bearing and a bumper comprising a first portion made of a comparably incompressible material and a second portion made of a comparably compressible material. The bumper is mounted on the frame such that the bumper moves upon impact with an object, compressing the compressible material. For example, the incompressible material may be a polyamide and the compressible material may be a neoprene extrusion.

Vehicle barrier systems that can selectively move a barrier arm between a first position that prevents a vehicle from passing, or a second position that allows the vehicle to pass, wherein the barrier arm moves both upwardly away from a travel path and laterally along the travel path in a direction away from the vehicle. The barrier arm movement thereby leads the driver of the vehicle through the barrier system in a sweeping or leading movement. In some embodiments, an actuator assembly of the barrier system includes a breakaway assembly coupled to the barrier arm. In the event that an abnormal force (e.g. vehicle strike, vandalism, etc.) applied to the barrier arm exceeds a predetermined threshold, one or more drive magnets of the breakaway assembly disengage from the one or more magnetically-attractive elements to prevent damage to the barrier system.

A hinge apparatus that includes a stationary hinge portion, which includes a first bracket configured to be attached to a fixed surface, a first arm extending from the first bracket, and a second arm extending from the first bracket. The first and second brackets include axial holes with a hinge pin arranged therethrough. The hinge pin defines a rotation axis. The stationary hinge portion also includes a stop plate extending away from the first bracket and connected to the first arm. The hinge apparatus also includes a rotatable hinge portion, which includes a body arranged around the hinge pin between the first and second arms and a stop body extending from the body along the rotation axis. Ends of the stop body contact the stop plate to limit rotation of the body about the rotation axis. A second bracket configured to be attached to a movable body.
