摘要:
A gate operator in a first configuration opens and closes a gate that swings about an upstanding pivotal axis. In a second configuration the gate operator opens and closes a gate that extends and retracts along a straight line. A motor-driven wheel extends from the bottom of an open-bottomed enclosure and is perpendicular to the gate in the first configuration and parallel to the gate in the second configuration. The wheel is driven by a reversible DC motor. Turning a jack screw in a first direction increases the bias on an adjustable compression spring so that the weight of the gate is transferred to the wheel and rotation of the jack screw in an opposite direction shifts weight from the wheel to the gate.

A handle for a window operator. The handle (10) is formed by a lever handle rotatably coupled to a mounting (12) which is pivotally mountable by pivot axles (22). A spigot mount (15) of the handle (10) is hingedly connected to a drive shaft (18) which is engageable with the drive mechanism of the operator. Clearances (16) and (23) of the spigot mount (15) and mounting (12) respectively can be aligned at a certain angular position of the lever handle (11) relative to the mounting (12) to enable the handle (11) and mounting (12) to be pivotally moved about the axis of axles (22). A latch operating member (29) can be coupled to the mounting (12) so that as the mounting (12) is pivotally moved about the axis of axles (22) the latch operating member can be moved to operate a window latch.

An auxiliary operating device for manually operating a normally motor-operated closure between open and closed positions, the device comprising a shaft, a driving member mounted to the shaft and displaceable between an idle position and an operational position wherein the driving member is operatively coupled to the closure. The device further comprises a manual actuator for first displacing the driving member from its idle position to its operational position and then driving the driving member in order to displace the closure. The actuator can be advantageously mounted at either end portions of the shaft irrespectively of the position of the driving member on the shaft.

An apparatus for shutting off power to a gate motor is disclosed when the gate to which the gate motor is connected is opened or closed manually. In a preferred embodiment a sensor is activated that immediately shuts off power to the gate motor upon insertion of a crank into a receptacle on a pulley of the power driven gate movement system to commence manual opening or closing of the gate with the crank. Rotation of the crank in the appropriate direction either opens or closes the gate. Power is restored to the gate motor when the sensor determines that the crank has been withdrawn from the pulley.

A running carriage arrangement (1) includes a housing receptacle (5) and a housing (9) embedded in it. The running carriage (7) can be vertically shifted within the housing (9). The shifting of the running carriage (7) is accomplished by an adjusting wheel (39), which can be rotated by hand and by which the running carriage (7) can be adjusted relative to the housing (9) and the sliding door (3).

A foot pedal door opener device for use with a reach-in commercial cabinet, having a mounting bracket and retaining clip that allow the foot pedal to be mounted in a desired position for a left or right side opening door. The mounting bracket has at least two holes in a top portion of the bracket body to retrofit or mount the bracket to an outer surface of the cabinet. The retaining clip is configured to be aligned with either one of the holes of the bracket body. A connector passes through the retaining clip and corresponding hole of the bracket and penetrates the outer surface of the cabinet to secure the retaining clip to the bracket body and the mounting bracket to the cabinet. The pedal engages a rotating member that connects the pedal to the mounting bracket such that when a user depresses the pedal, the pedal rotates toward the user around the rotating member, whereby an engaging head of the pedal pushes the cabinet door open.
摘要:
A gate opening apparatus which utilizes a horizontably swingable arm assembly which is to be operated electrically to effect movement of a gate between a closed position and an open position. The arm assembly is mounted through a latching mechanism to the motor mechanism of the gate opening apparatus. This latching mechanism can be manually released which will permit the arm assembly to pivot through a vertical plane so as to provide for manual movement of the gate between the open and closed position during instances when electrical power is not available to operate the gate opening apparatus.
摘要:
A door operator mechanism which has a motive power source and drive and a manual drive for use with a manual source of power. A mechanism is included which by the simple expedient of pulling a chain or cable disconnects the power source and associated driver and connects the manual drive for use of a manual source of power. Release of the cable causes the reverse.

A retractable roof system for motor cars, said system comprising: a plurality of nesting shutters interconnected for movement between a nested position and an extended position in which each shutter overlaps an adjacent shutter and the outer surfaces of said shutters altogether define a substantially horizontal essentially continuous, stepped, extended surface, a pair of fixed guide members adjacent, respectively, the lateral margins of said extended surface, and followers attached to the shutters for cooperation with guide members to position the shutters so that said extended surface generally matches a desired surface for said roof system. The system includes interchannel sealing strips which inhibit the passage of wind and rain into the motor car and also serve to reduce vibration by compressing and maintaining spacing between the several shutters.
摘要:
A door operator for driving a track guided door through opening and closing cycles, including a rotating shaft and drive member movable therealong in response to rotation wherein the drive member is resiliently coupled to a door. A locking mechanism is provided for locking the door in closed position and an emergency device enables opening of the door when power is not available.
