Abstract:
A drive includes a motor (5) and at least one gear assembly (7) that is connected downstream of the motor (5) for vehicles comprising a door (1) that can be closed automatically. The output shaft (28) of the gear assembly (7) is disengaged from the drive shaft (27) in such a way that during the manual actuation of the units connected to the output shaft (28), (e.g. tailgate of the vehicle,) their displacement is not restricted by the units connected to the drive shaft (27) of the coupling (e.g. electromotor (5) or intermediate gear (6)), thus preventing wear of the units. The gear assembly (7) can be disengaged and comprises a gear-assembly housing (21) with a cylindrical cavity (22), in which a planetary gear (23;38), provided with a housing (26;39) and concentric drive and output shafts (27,28), is rotatably mounted.
Abstract:
A system and method for decoupling a barrier from a barrier movement apparatus for the manual operation of the barrier. Advantageously, the decoupling is performed in response to a wireless signal and may be done only when the barrier is determined to be in a safe position.
Abstract:
A power liftgate drive assembly automatically moves the liftgate of a vehicle between its open and closed positions. The drive assembly is secured to the vehicle at a position near the top of the liftgate. The drive assembly includes a motor that drives a sector gear between two positions. A guide rod is secured to the sector gear to translate the rotational movement of the sector gear into the pivotal movement of the ligtgate. A slot extends through the sector gear that allows the liftgate to be moved manually. A latch locks the guide rod in position with respect to the sector gear for automated movement whereas the latch releases the guide rod to move in the slot for manual operation.
Abstract:
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).
Abstract:
A power liftgate device for a liftgate of a vehicle having a power drive unit and a pneumatic actuator. The pneumatic actuator is pivotally coupled between the liftgate and the vehicle and exerts a force opposing retraction of the liftgate. A driven gear is fixed to the pneumatic actuator to pivot therewith and is selectively driven by the power drive unit. The liftgate assembly further includes an engaging device that is coupled to the vehicle for engaging the power drive unit with the driven gear, thereby enabling the power drive unit to drive the driven gear. Specifically, the engaging device is positionable between an engaged and a disengaged position, wherein the engaging device is operable in the engaged position to engage the power drive unit into driving connection with the driven gear. The engaging device is also operable in the disengaged position to disengage the power drive unit from the driven gear to enable the actuator to actuate freely.
Abstract:
A side mount garage door operator capable of being positioned on either the ceiling or end wall of a garage at either side of the garage door on a frame unit, the operator providing a clutch for disengaging the drive motor from the garage door in the absence of electric power and having a manual graspable handle operated by a solenoid when power is present and operable manually in the absence of power. Novel limit means having limits which is on the end of an axially movable bar which is moved by a follower riding in a spiral groove in the base of a disk such as a gear connected to the drive shaft.
Abstract:
An oven door hinge having stable positions in closed, broil and open positions of the door includes an elongated support member which extends along the side of the door, and a hanger with an elongated arm portion which removably seats in a recess adjacent the lower side of the oven cavity. The hanger also has a depending hinge portion which is pivotably supported on the support member adjacent its lower end. A translation member has its lower portion pivoted to the hanger arm portion, and an upper portion which is disposed within the support member. A spring is connected between the upper portion of the translation member and the upper end portion of the support member so that opening of the door displaces the translation member relative to the support member and hanger and tensions the spring. The support member and translation member have cooperating positioning elements to bias the door into its closed position and to hold the door in its broil position.
Abstract:
The manually releasable stop device permits unimpeded swinging of the window within a limited angle of rotation between the closed and partially open window. After releasing the stop device further swinging of the window is permitted beyond the limited angle of rotation. The stop device comprises two cooperating stop members (25, 26) which are fastened to respective support members (14, 18) in the window hinge which are pivotable relative to each other. A first stop member is constituted by a stop element (26) fixedly fastened to the one support member (14), and the second stop member is constituted by a self-locking catch element (25) fastened to the other support member (18). The catch element cooperates with a positive control mechanism (26, 32, 37, 39) in the pivotal region of the window within the limited angle of rotation. In the pivotal region the positive control mechanism is adapted to forcibly control the catch element (25) to engage with the fixedly fastened locking element (26), while the catch element in the pivotal region is designed for limited movement of the catch element relative to the fixed locking element.
