A traffic gate apparatus comprises an upstanding pedestal. A first elongate arm is also provided having a proximal end and a distal end, with the proximal end of the first elongate arm being pivotally connected to the pedestal at a first pivot axis. A second elongate arm has a proximal end and a distal end, with the proximal end of the lower elongate arm being pivotally connected to the pedestal at a second pivot axis. The second pivot axis is below the first pivot axis such that the first and second elongate arms are movable between a lowered position, in which the first and second elongate arms are generally horizontal and parallel with the first elongate arm being above said second elongate arm, and a raised position. The first and second elongate arms each have an adjustment mechanism such that a length thereof can be varied.

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.

The present disclosure relates to an articulated-arm drive, in particular for a swing gate, with a drive unit comprising an output shaft and an articulated arm, wherein the articulated arm comprises a first and a second articulated-arm member, which are rotatably connected to each other by means of a first rotary joint, wherein the first articulated-arm member is connected or connectable to a stationary first pivot point at the end facing away from the first rotary joint, and wherein the second articulated-arm member is rotatably connectable to a gate at the end facing away from the first rotary joint. In accordance with the disclosure, the end of the first articulated-arm member facing away from the first rotary joint is not connected to the output shaft and the output shaft is connected to one of the articulated-arm members via a coupling arm.

A gate latching system is provided. A gate latching system installed onto a gate hinged to a stationary post for covert, one-handed operation, the gate latching system comprising a latch bar mounted to an interior side of the hinged gate via a plurality of fasteners where a first end of the latch bar rests against the stationary post preventing the gate from opening in an inward direction. The latch bar having a latch affixed next to the first end of the latch bar. An operator lever affixed at a midpoint of the latch bar and a stiff wire connector coupled to the latch and the operator lever and a latch coupling fastened to the stationary post in plane with the latch to optionally couple with the latch.

A gate opening apparatus includes an external housing, a main chassis, a motor device, a driving rotor, a plurality of guiding rollers, a transmission chain connecting the driving rotor, the guiding rollers and a door gate, and a gate actuating arrangement. The gate actuating arrangement includes a clutching device supported on the main chassis and connected to the motor device, a limit switch assembly coupled to the clutching device, and a control module. The gate opening apparatus is arranged to operate between a power mode and a manual mode. In the power mode, the clutching device is engaged with the driving rotor for driving a movement thereof by the motor device so as to selectively open and close the door gate. In the manual mode, the clutching device is disengaged from the driving rotor so that the driving rotor is adapted for being rotated manually.

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 connecting device connects between the open ends of tubes of two adjacent frames within a cantilevered structure. The device is a bridging apparatus having opposing first and second portions received within the open ends of the tubes. First and second sets of circumferentially spaced fasteners bores in respective first and second portions of the bridging apparatus align with bores in the tubes so that fasteners threaded into the fastener bores clamp the first and second portions against corresponding inner surfaces of the tubes at each fastener location. In this manner, the fasteners in both tubes are oriented in different radial directions such that the bridging apparatus is better suited to bracing adjacent frame sections in a cantilevered structure such as a gate panel against a variety of different loads from different directions, including wind loads and the like.

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 horizontal adjustable hinge system that is capable of replacing existing hinges. The adjustable hinge assembly comprises of a first and second horizontally mounted support legs which comprise of two elongated slots for fasteners. These elongated slots for fasteners allow for adjustment of the distance between the fixed support structure and the movable structure. There is also two square holes for additional fortifying of the hinge assemble to the structure. The system also has a vertical mounted pole bracket capable of acting as a clamp over a standard post pole and having a multiplicity of openings for the insertion of fasteners.

A traffic gate apparatus comprises an upstanding pedestal. A first elongate arm is also provided having a proximal end and a distal end, with the proximal end of the first elongate arm being pivotally connected to the pedestal at a first pivot axis. A second elongate arm has a proximal end and a distal end, with the proximal end of the lower elongate arm being pivotally connected to the pedestal at a second pivot axis. The second pivot axis is below the first pivot axis such that the first and second elongate arms are movable between a lowered position, in which the first and second elongate arms are generally horizontal and parallel with the first elongate arm being above said second elongate arm, and a raised position. The first and second elongate arms each have an adjustment mechanism such that a length thereof can be varied.
