Abstract:
A brake device for damping a translatory motion having a bearing housing and a brake disk both made of a resilient, hard elastic plastic material. The brake disk is supported for rotation in the bearing housing and adapted for rotation in response to a translatory motion, the brake disk having an outer conically shaped friction surface and the bearing housing a correspondingly configured inner conically shaped friction. The surfaces are held together when the disk is supported in the housing to generate frictional resistance between them as the disk rotates in the housing in response to a translatory motion and thereby dampen the motion.
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 mechanism for controlling the raising and lowering of a door comprising a speed reduction gearing, a high speed input shaft and a low speed output shaft connected to the gearing, and a governor mounted on the input shaft for regulating the input shaft's rotational speed. More particularly, the mechanism is provided with a brake having a movable brake shoe, a temperature sensitive link and an elongate member having a central portion coupled to the brake shoe. As well, the first portion of the elongate member is engageable with the temperature sensitive element and a second portion of the elongate member is engageable with the actuator. In this way, the elongate member is provided for moving the brake shoe to the release position in response to one of (1) the temperature sensitive link upon the temperature reaching a predetermined temperature and (2) the actuator.
Abstract:
An oven door is provided with a mechanism for controlling the rate of door opening and closing. The mechanism includes first and second parts pivotably connected to the oven body and oven door, respectively. A rotary element interconnects the first and second parts in such manner that those parts are relatively longitudinally movable when the door is opened and closed, and such that the rotary member is induced to rotate in response to such relative movement. The rotary member frictionally engages the first and second parts such that relative movement between the parts produces friction forces tending to resist such relative movement and thereby control the rate of opening and closing of the door.
Abstract:
Herein disclosed is a continuous speed change type door check for closing a door, which comprises: a pivot pin made rotatable; a slider adapted to be linearly moved by the rotations of the pivot pin and to rotate the pivot pin when it returns; a coil spring for biasing the slider to return; a gear train for speeding up the rotations of the pivot pin; a brake connected to the gear train; and a one-way transmission clutch for operating the brake in a direction to close the door.
Abstract:
A device for motorized opening and closing of pivotable body panels of motor vehicles, especially the rear trunk lid or rear hatch and/or the hood of automobiles, has a motor-actuated lever system engaging in an articulated manner, on the one hand, with the body panel, and on the other hand, with the body. The body end of the lever system is articulated at a slide block guided slidingly in a guide track. The slide block is operatively connected to a driver that is secured to a control cable. The ends of the control cable can be wound onto or off a common cable pulley actuated by an electric motor.
Abstract:
A safety device for preventing accidental unrolling of a rolling shutter or overhead door comprising a cogwheel which has uniformly distributed on the circumference opening outward for containing radially movable tumblers, a cage which surrounds the cogwheel that contains an abutment in the form of a recess for the tumblers which are raised by the action of centrifugal force. Upon reaching a predetermined rotational speed, the tumblers engage an abutment in the cage and the cage acting as a brake is then driven by the cogwheel and slowed down by friction.
