Abstract:
A direction switchable ratchet device for a door operator is provided. The door operator includes an electric motor, an electromagnetic brake and the direction switchable ratchet device. The direction switchable ratchet device comprises a first and second direction restricting devices and a manually operable mechanism. A drive shaft of the electric motor is braked by a brake baffle disk when the electric motor is electrically de-energized and is released when the electric motor is electrically energized. The first and second direction restricting devices are provided to prevent the drive shaft from being rotated clockwise and counter-clockwise respectively by holding the brake baffle disk. In the event of power failure, the manually operable mechanism is effective to open the door once a pawl of the direction restricting device at the free side is retracted. The manually operable mechanism of the door operator is prevented from being incorrectly mounted in a cost-effective manner.
Abstract:
An electrically powered vehicle tailgate operator for pivoting a tailgate of a pickup truck about a horizontal tailgate axis near a bottom edge of the tailgate. The vehicle tailgate operator comprises a cable spool for spooling a cable and a drive gear for transmitting torque from the drive shaft to the cable spool. The vehicle tailgate operator also has a retention system. The cable spool, the drive actuator, the drive shaft, the drive gear, and the retention system are arranged inside of a housing, wherein the spool axis is oriented in parallel to the drive shaft axis and the spool axis is arranged on the same height or above the drive shaft axis.
Abstract:
A gate lock (10) includes a body (11), which in turn includes a latch (12) that can house a key (13) for opening the lock (10) and a stop element (14) having a first configuration of engagement on at least a part of the gate. The lock (10) further includes a slide (17), which slides with respect to the body (11); the stop element (14) is slidably constrained to a guide element.
Abstract:
A piece of furniture has an actuating arrangement for a flap of the piece of furniture. An actuating arm arrangement includes a lever arrangement for moving the flap and a main spring that acts in the closing direction (SR) to hold the flap closed. The piece of furniture also has an ejecting device for ejecting the flap in the opening direction (OR) by overpressing the flap in the closing direction (SR). At least one support spring acts in the opening direction (OR) and is separate from the ejecting device, and supports the ejecting motion of the ejecting device. At least in an overpressed closed position (US), the spring forces (A, U) are together greater than the closing force (Z) which acts on the flap and which is provided by the main spring acting in the closing direction (SR).
Abstract:
A hanger hinge for a folding door, window or similar closure having one or more panels, the hanger hinge comprising: A hanger bolt having a receiving portion in a lower end thereof adapted to receive at least a portion of an adjusting tool; A sleeve adapted to be supported on the lower end of the hanger bolt; At least one hinge leaf pivotally mounted on the hanger bolt and adapted to be fixed to a respective panel; and A locking mechanism comprising a locking member movable axially between a locked condition in which the locking member is engaged with the sleeve in a manner to substantially preclude rotation of the hanger bolt relative to the sleeve, and an unlocked condition in which the locking member is disengaged from the sleeve by axial insertion of the adjusting tool into the receiving portion, thereby freeing the hanger bolt for rotation relative to the sleeve.
Abstract:
A hinge including a first hinge half rotatably connected to a second hinge half is described. A support mechanism selectively supports the first hinge half at one or more rotated positions relative to the second hinge half. The support mechanism includes a support which is selectively biased toward a support position in which the support is capable of supporting the first hinge half at a rotated position relative to the second hinge half. The support can further be selectively biased into a disengaged position in which the support is not capable of supporting the first hinge half relative to the second hinge half. With the support in a disengaged position, the first hinge half is freely pivotable relative to the second hinge half. An automatic reset mechanism may be utilized in connection with the hinge to reposition the support from the disengaged position to the support position as the hinge approaches a predefined position.
Abstract:
The invention is a security trolley lock for garage door openers. The trolley lock is a “U-shaped” element that removably attaches to a garage door trolley for preventing lateral access to the release lever of a garage door opener system. The trolley lock has a pass-through opening for allowing attachment of said trolley to a garage door trolley and another pass-through opening for receiving a lock means preventing unauthorized actuation of the release lever.
Abstract:
A clutch switching device for electric rolling doors contains: a housing, a rotating plate, and a shifting bar. The rotating plate is provided in the housing for connecting with the clutch pulling cord. The shifting bar is coupled with the rotating plate and is pulled to drive the rotating plate to move toward a manual mode position or an automatic mode position. The rotating plate has a wrenching portion for matching with a wrench tool so as to wrench the rotating plate. The housing includes a movable fixing element, the rotating plate has a first positioning aperture and a second positioning aperture, such that when the rotating plate is located at a manual mode position, the first positioning aperture aligns and retains with the movable fixing element; when the rotating plate is located at the automatic mode position, the second positioning aperture aligns and retains with the movable fixing element.

Abstract:
A window assembly including a frame having an interior portion with an inner surface, and a sash having an interior portion and an exterior portion. The window assembly includes an operational mode and a wash mode. In the operational mode, the sash is movable from a closed position to a position in which the sash is generally perpendicular with the frame. In the wash mode, the sash is movable to a position where the exterior of the sash faces toward the interior frame.
