Abstract:
A window regulator provided in a door of a vehicle to raise and lower a windowpane in the door. The window regulator includes a traveling body that holds the windowpane and travels together with the windowpane, a wire that pulls the traveling body, and a drive mechanism that generates a drive force to wind the wire. The traveling body includes a sub-housing that encloses at least a portion of the drive mechanism. The traveling body includes a recessed groove into which the wire is inserted and which has a depth in a plate thickness direction thereof. The sub-housing is fixed to the traveling body while striding across the recessed groove.
Abstract:

Abstract:
A powered garage door opener is provided for operating a garage door between an open and closed position. The powered garage door opener comprises a main housing mounted adjacent the garage door. An electric motor and gear train assembly is mounted within the main housing and coupled to the garage door to drive the garage door between the open and closed positions. A power supply is mounted within the main housing and electrically connected to the electric motor and gear train assembly. A control module is mounted within the main housing and electrically connected to the power supply and the electric motor and gear train assembly for controlling selective actuation of the electric motor and gear train assembly. The electric motor and gear train assembly includes a secondary housing, an electric motor sealed within the secondary housing, a worm gear coupled to and driven by the electric motor, a spur gear in meshed engagement with the worm gear, and a driven shaft mounted to the spur gear and coupled to garage door. The electric motor provides electrical power to drive the worm and spur gears, rotating the driven shaft, to provide power actuation of the garage door and the gear relationship between the worm gear and spur gear allows the spur gear to back drive the worm gear and provide manual actuation of the garage door.
Abstract:
A damping device for furniture doors includes a damping cylinder longitudinally displaceably mounted in a recess of a damper housing including a cylinder housing and a piston rod and forming a stop for the furniture door. The cylinder housing is longitudinally displaceably mounted in the recess of the damper housing, the recess being formed as a hole, the end thereof protruding out of the damper housing forming a stop for the furniture door. The adjusting screw forms an axial counterbearing for the piston rod. The inner diameter of an internal thread receiving the adjusting screw is at least equal to the inner diameter of the hole receiving the cylinder housing. The end of the piston rod is received in a centric hole of the adjusting screw.
Abstract:
A slide gate comprising: a frame assembly which defines an opening through which fluid flows; a slide plate movably mounted to the frame assembly for vertical movement relative thereto so as to selectively open and close the opening in the frame assembly; an operating mechanism for vertically moving the slide plate between its open and closed positions so as to regulate fluid flow through the opening in the frame assembly, wherein the operating mechanism comprises a threaded operating stem which is secured to the top of the slide plate and which extends through a threaded operating nut which is rotatably mounted to the frame assembly, and means for rotating the threaded operating nut so as to cause longitudinal movement of the threaded operating stem relative to the threaded operating nut, so as to raise or lower the slide plate, whereby to open or close the opening in the slide gate; and a threaded fall-protection nut disposed on the threaded operating stem in spaced relation to the threaded operating nut and configured to rotate in unison with the threaded operating nut, the threaded operating nut being spaced from a fall-protection stop plate which is connected to the frame assembly.
Abstract:
The invention relates to an electric door-locking system to be applied to at least one electric door body that is movable in a sliding manner, and includes forwardly and reversely rotatable screws disposed side by side along a direction in which the electric door body slides at the side of a door frame; a cam assembly provided at a predetermined position of the screws to perform a locking function and an unlocking function; and a sliding unit provided with a locking roller resiliently biased in a direction toward the cam assembly and engaging with the cam assembly to perform the locking function, one end of the sliding unit being rotatably connected to the screw and the other end of the sliding unit being connected to the electric door body.
Abstract:
The invention relates to an actuating drive for moving a flap of a piece of furniture, comprising: at least one pivotably supported actuating arm for moving the flap, a spring device for applying a pivoting torque to the actuating arm in the opening direction, and an adjusting device having an adjusting screw, which has a thread, wherein the pivoting torque of the spring device acting on the actuating arm can be adjusted by means of a rotational motion of the adjusting screw, wherein the adjusting screw has a screw shaft, wherein a screw nut is supported in such a way that said nut can be moved along the screw shaft by means of a rotational motion of the adjusting screw, wherein the adjusting screw has a blocking device separate from the thread, which blocking device prevents an unintentional rotational motion of the adjusting screw.
Abstract:
A window regulator cable tensioner includes a screw and nut assembly having an irreversible thread lead angle, a first spring to absorb reversible slack in the cable, and a second spring to actuate movement of the screw and nut assembly. The stiffness of the first spring is greater than the stiffness of the second spring. The cable tensioner absorbs the reversible slack in the cable differently from irreversible slack in the cable.
Abstract:
The carriage, which serves for holding a slidable separation element, comprises a carriage body and at least one running wheel, which is a rolling along a rail when the separation elements is displaced. According to the invention the carriage body comprises a housing with an interior space, in which a holding unit is provided, which is protruding through an opening out of the housing and which is seated slidable in a direction at least approximately vertically to the running direction of the carriage, and which the holding unit comprises a holding element that interacts within the housing with an adjusting element, that is displaceable in relation to the holding element by means of an adjusting screw, which is held by the carriage body, so that the holding unit is held at a selected position, whereas either the part of the holding unit that is protruding out of the housing is provided with the at least one running wheel and the carriage body is connected to the separation element; or the part of the holding unit that is protruding out of the housing is connected to the separation element and the carriage body is provided with the at least one running wheel.
