Abstract: A novel electrical floor-hinge device is provided, which contains an electrical motor and a speed reducing element configured on top of a platform element at a side on top of a body member. A vertical input shaft connected to the speed reducing element is joined to a lateral involute shaft via bevel gears. The involute shaft in turn engages a driven gear on a vertical output shaft. The top end of the output shaft is attached to a seat element whose top surface is fixedly joined to a lower inner corner of a door. By the electrical motor's driving the seat element into clockwise or counterclockwise swing, the door is closed or opened automatically. The speed reducing element can be easily replaced to fit doors of different weight.

Abstract: An automated car door opening system proposes a very simple yet reliable system that can easily be retrofitted on most cars. It uses the combination of a large electrically actuated inner shaft cooperating with a piston. The piston opens the car door slightly in a manner similar to the normal opening of a car door, so that the door clears the car frame and then, a combination of outward but more predominantly upward motion by the inner shaft has the door opening in an upwardly rotational motion along a vertical plane which fully opens it. The reverse process closes the door.

Abstract: A window-regulating assembly selectively moves a window of a vehicle door between an open position and a closed position. The window-regulating assembly includes a rail that is fixedly secured to the vehicle door. The rail extends through a radius of curvature. A lift plate is slidably engaged with the rail. The lift plate is also secured to the window. The lift plate moves the window between the open and closed positions. A lead screw is secured to the rail. The lift plate travels along the lead screw to move the window between the open and closed positions. A drive motor is secured to lift plate. The drive motor receives electrical energy and converts the electrical energy into a selectively bidirectional rotational force to drive the lift plate over the lead screw. A pivot mount extends between the drive motor and the lift plate allowing the drive motor to move through the radius of curvature as the lift plate slides along the rail.

Abstract: An actuator for gates, doors and the like, with at least one wing. The actuating motor (14) and the associated motor reduction unit (15) are housed inside as half-arm (2) which turns on a fixed support (9) in an oscillating way about a substantially vertical swinging axis (10). Advantageously, the electric motor (14) operates a maneuvering worm screw (12) which is carried by said half-arm (2) and engages a corresponding helical gear (13) coaxial with the swinging axis (10) and is fastened to the fixed support of the half-arm (2) by a torque-limiting device which prevents excessive stresses on the actuator as a result of external forces and also makes it possible to release the helical gear for manual emergency actuation of the wing.

Abstract: An assembly, preferably comprising a clearance pole, includes a first pole element with a first horizontal portion and a second vertical portion, and a second tubular pole element mounted to the ground, extending vertically, and receiving the first pole second portion. The first and second pole elements are mounted so that the first element is rotatable with respect to the second about a vertical axis. The slanted surface of an ultra-high molecular weight polyethylene block acts as a cam follower engaging a rod, bar, or tube which acts as a cam, the structures biasing the first pole element first portion to a home position. A dry lubricant is provided between the pole element bearing surfaces to provide relatively friction-free rotation between them.

Abstract: A housing assembly for a window operating assembly having a drive shaft and drive shaft boss having recesses on opposite sides thereof. The housing assembly includes a cover having a top side with an opening therethrough and sides depending from the top side to define an interior and an exterior. The cover is open on the interior for receiving a portion of the window operating assembly including a drive shaft boss portion with a portion of the drive shaft extending through the top side opening to the exterior. The depending sides having outer edges mateable with a window operating assembly to maintain alignment of the cover with a substantial portion of the operating assembly housed by the cover. A discrete connecting member is secured to the cover interior and includes an oblong opening with a narrow portion having a radial dimension less than that of the drive shaft boss.

Abstract: A universal window-actuator drive unit capable of use with either a cable pulley window-actuator or an arm-scissors type window-actuator. A worm shaft extends from a driving motor and is rotatably coupled to a worm gear. The worm gear is coupled in a rotational-slave relationship to a driving disk, and both the worm gear and the driving disk are rotatably supported on a gear housing shaft. At its end opposite the driving disk, the gear housing shaft includes an actuator shaft collar concentrically surrounding the gear housing shaft and having a grooved toothing about its inner circumference. This inner grooved toothing enables the window-actuator drive unit to be coupled to either a drive pinion of an arm-scissor type window actuator or a cable pulley of a cable pulley window actuator, each of which include couplings having an outer grooved toothing corresponding to the inner grooved toothing of the actuator shaft collar.
