Abstract:
A clutch selectively transmits torque and rotary motion from a spindle having an axis of rotation to a drum. First and second shoe members disposed radially between the spindle and the drum move radially with respect to the axis of rotation between an engaged position and a disengaged position with respect to the drum. The first and second shoe members are responsive to acceleration for moving into the engaged position and responsive to rotational speed for moving into the disengaged position. A biasing spring normally maintains the first and second shoe members in the disengaged position when the spindle is at rest.
Abstract:
A pivoting and sliding closure assembly is provided which rides in a guide channel of a frame upon a pivot shoe assembly which at one end securely pivots a closure member upon one pivot shoe when the closure is pivoted away from the channel, and which latches the closure member in a slidable position when the closure member is pivoted to its latched position. The pivot shoes are connected together in the assembly and unique cam structures and rollers are incorporated in the assembly.
Abstract:
A door hinge is disclosed including a door mounting bracket and a body mounting bracket interconnected by an intermediate member pivotably attached to each bracket. A locking arrangement including a pivotable locking arm on the intermediate member simultaneously locks and unlocks the intermediate member with the respective mounting bracket at the closed and an intermediate open position of the door providing for sequential, reversible pivotable movement of the intermediate member and door bracket as a unit about the pivot point on the body bracket between the closed and intermediate open position and independent reversible pivotable movement of the door mounting bracket between the intermediate open position and fully open position of the door.
Abstract:
A drive mechanism for full-automatic opening and closing of a sliding door comprises two drive mechanisms for supplying different moving speeds to the door. A main motor for the higher speed drives a worm-gear spindle, a low-power motor for the lower speed drives a profiled bar. A gear wheel moving on the worm-gear spindle and a pinion slideably mounted on the profiled bar mesh with each other and are contained in a sliding carriage guiding the sliding door via a latch. The selective or common drive of both motors results in various combinations and enables an adaptation to the requirements for variable door speeds. The drive mechanism is of simple design, relatively cheap and does not require trained service personnel.
Abstract:
A window in a motor vehicle is mounted for pivotal movement about a pivot element. An electric motor drives a gear unit whose output shaft is coupled with the pivot in such a manner that pressure manually exerted upon the window disconnects the output shaft from the pivot so that the window can be manually moved in the event this is desirable or necessary because of malfunction of the motor or the gear unit.
