摘要:
This invention relates to an overhead door closer with slide arm assembly (1) having a toothed pinion (6) that is eccentrically supported and presents a circular rolling curve, which pinion meshes with a toothed rack (5) arranged at a piston (4). The invention concentrates on a particular embodiment of the rolling curve and of the teeth (9) of the toothed rack (5) in adaptation to a toothing of the pinion (6). Furthermore, the invention concentrates on an improved embodiment of the delayed closing operation in order to achieve an optimized movement pattern of the piston (4) within the housing (2) of the overhead door closer with slide arm assembly (1).

A reinforcing block for a closure tilt latch, comprising a body fastened in a closure track fastened to a frame, said body having a top and bottom and having a locking detent extending therein said locking detent providing a vertical face extending toward said top of said body from intermediate said top and bottom, the tilt latch being compatible with the vertical face of said locking detent, wherein when said latch engages said detent said block provides a reinforcement path to the closure frame to strengthen the loading capability of said closure and to reduce the risk of the latch from disengaging said track under loading which track would be subject to distortion had the block not been utilized.

A universal power operator for shifting a movable barrier, such as a gate, and a circuit control system for operation thereof, is shown that allows the operator to be assembled for both a left-hinged or right-hinged movable barrier. The universal power operator includes generally an actuator arm, a housing assembly, a gear assembly, and a modular drive motor. The housing assembly contains generally symmetrical portions allowing the user to interchangeably assemble the motor in one of two positions for use with a left-hinged or right-hinged movable barrier.

This sliding sash drive assembly includes a rack gear for the sash and a drive unit adapted to be mounted on the window frame and having a driven spur gear. An L-shaped engagement lever is mounted at its vertex on the housing and carries on its short leg a rack guide adapted to embrace the rack gear so that, as the long leg of the lever is moved, the guide moves the rack to a position at which the rack meshes with the spur.

A drive apparatus, in particular for the automatic actuation of a sliding door of a motor vehicle, comprising a fast running motor, the motor shaft of which is connected to a transmission with a large step-down ratio, the transmission having a first gear wheel which can be secured against rotation, via a releasable blocking device, and a second rotatable gear wheel which is rotationally fixedly connected to an output drive shaft and which is rotatable relative to the first gear wheel by the rotation of the motor when the first gear wheel is blocked, with the number of teeth of the first gear wheel only differing by a few teeth from the number of teeth of the second gear wheel and with the large step-down ratio being determined by this difference of the tooth numbers. By releasing the blocking device, the step-down ratio of the transmission changes. In particular a step-down ratio of 1:1 results. The transmission is thereby capable of being driven in reverse, so that a manual actuation of the sliding door of a motor vehicle is possible, without the requirement for a releasable clutch device between the sliding door and the drive apparatus.

An actuation device for motor vehicle parts that are movable by an electric motor, in particular for window regulators and sliding roofs that are driven by a reversible electric motor. This actuation device has a setpoint value device for the desired position of the movable part, an incremental actual-value device for producing a signal corresponding to the actual position of the movable part, an absolute actual value device which emits first and second signals that are positionally fixed relative to the incremental actual-value device, and a microprocessor to compare the setpoint and actual value signals and to perform control and regulation programs. The signal emitted by the absolute actual-value device changes only at predetermined position values and the absolute actual-value device has position zones which are separated from one another by these position values that can be predetermined. The first and last position zones are each defined by a first or second end position of the movable part. The absolute actual-value device has at least five separate position zones and emits the first signal in the first and last position zone, and the first and last position zone are wider than all other position zones in which the absolute actual value device emits the first signal.

A driving mechanism is disposed in the bottom of a door for driving the door and includes a reduction gearing and a motor fixed to the door, and a gear coupled to the reduction gearing and engaged with two shafts for rotatably supporting the wheels of the door so as to apply a downward force to the pinions in order to prevent the wheels moving upward away from the tracks. A retaining device is fixed to one of the tracks or fixed to the ground and has an opening for engaging with one of the pinions so as to maintain the door in place.
摘要:
A door operator for an overhead garage door having a reversible electric motor and a gear train driving the door. Limit stops are provided, one for the "up" limit and another for the "down" limit. Each of the limit stops is independently zero setable to cut off current to the motor at a pre-selected position.

A door which is to be swung open and closed to provide access to an enclosure and slid back into the enclosure is provided with one or more hinges rotatably mounted on a shaft to the ends of which there are fixedly mounted gears which positively engage respective racks disposed adjacent the top and bottom of the enclosure and extending along the depth of the enclosure so that as each door is slid in and out of the enclosure there is no rotation of the door in its plane and, hence, no sagging and binding of the door. A portion of each hinge is confined within a guide block which is in turn rotatably connected with the shaft and slidably mounted in a channel adjacent and parallel to the rack so that only the member of the hinge attached to the door is swingable with the pivot of the hinge being rectilinearly slidable with the door along the depth of the enclosure.
