Abstract:
A brake-equipped retracting device (3) returns a liquid crystal display device (1) from a deployed position (1B) to a stored position (1A) using an elastic returning force of a spiral spring (18) that is wound up when the liquid crystal display device (1) is opened by the rotational force of a motor. A braking force for preventing the liquid crystal display device (1) from returning with too much force is applied to an input shaft (17a) of a reducer by having a rope (21) whose tensile force increases and decreases in relation to the opening and closing of the liquid crystal display device (1) be wound around a slip clutch (15) that is connected to the input shaft (17a). In emergency situations such as when the rope (21) breaks, a centrifugal grip (53) of a rotation-restraining mechanism (50) strikes an engagement notch surface (56b) on a fixed side, and the rotation of the input shaft (17a) is forcibly halted. A retracting device for a liquid crystal display device comprising a braking device that has a simple structure, is reliable, is highly safe, and is low in cost can be realized.
Abstract:
A decoupler assembly is provided for allowing an alternator to be rotatably driven by a serpentine belt in an engine of an automotive vehicle and for allowing the speed of the belt to oscillate relative to the alternator. A hub is fixedly carried by a drive shaft from the alternator for rotation therewith. A pulley is rotatably journaled to the hub by a ball bearing assembly. A bare, helical clutch spring is operatively coupled between the hub and pulley for transferring rotational movement from the pulley to the hub during acceleration of the pulley relative to the hub by the serpentine belt and for allowing the hub to overrun the pulley during deceleration of the pulley relative to the hub. A torque limiter, preferably a spring or sleeve, is wrapped about the torsion limiting outward expansion of the torsion isolating the torsion spring from torques above a predetermined limit.
Abstract:
Gear unit and motor-driven gear unit for cable window lift system of motor vehicles, comprising drive and gear mechanism which cooperates with the drive and is coupled to rotatably mounted cable drum for winding/unwinding a cable of the system. Diameter of the cable drum of the gear unit ranges from about 22 mm to about 30 mm, preferably from about 24 mm to about 28 mm; gear ratio of the gear mechanism ranges from about 1:38 to about 1:55, preferably from about 1:42 to about 1:51. The cable drum has, on its end face, claws which engage in corresponding recesses on the end face of a worm wheel. Electric motors having maximum driving torque of only about 5.7 Nm can be used. The gear unit size can be reduced by about 40-50%, and it can be standardized for both electric and manual cable window lift systems for front or rear vehicle doors.
Abstract:
A drive system for regulating devices in motor vehicles comprising a housing containing a drive element of the regulating device, a disk armature motor provided with an armature disk, and a planet wheel transmission. The planet wheel transmission comprises an internal geared wheel fixed to the housing and provided with an internal gear, an output internal geared wheel connected to the drive element of the regulating device and provided with an internal gear, and a radially flexible ring, the external gear thereof partially meshing with the inner gears of the internal geared wheel fixed to the housing and of the output internal geared wheel, and the inner envelope surface thereof rolling on rollers arranged on a drive hub connected to the armature disk. A journal pertaining to the output internal geared wheel is centred between the fixed drive axle and a cylinder of the drive hub.
Abstract:
A mobile terminal having three parts rotatably interconnected by hinges. The terminal can be a mobile telephone having an operative position where a microphone and a loudspeaker are positioned for conversation. When not in operation, the terminal may be positioned around a user's wrist in a safe manner. Removing the terminal from the wrist requires operation of a release means or the overcoming of a predetermined force, which is a safety measure of the hinges and the terminal. The hinges provide a combination of snap or automatic rotation and freely selective rotational positions of the parts of the terminal.
Abstract:
A hinge is mounted in an appliance with a cover and a base and has a stationary bracket, multiple resilient spacers and a pintle. The stationary bracket is attached to the base of the appliance and has a tubular sleeve. The resilient spacers are mounted securely in the sleeve. The pintle is attached to the cover of the appliance and is mounted rotatably in the resilient spacers. With multiple resilient spacers, the area to provide friction between the resilient spacers and the pintle is increased. Therefore, the friction between the resilient spacers and the pintle is increased and is sufficient to easily hold the cover at any desired angle.
Abstract:
The invention relates to a bilateral drive for rotating in the one or the other direction of drive a drive wheel which is linked with an adjusting device. Said drive comprises a drive lever which can be rotated about a drive axis, starting from an initial position, in the one or the other direction. Said lever is linked with a coupling element for expanding a spring element that is at least partially supported by the cylindrical drive surface of the drive wheel and that entrains the drive wheel in the peripheral direction when the drive lever is moved away from the initial position, while the spring element is no longer supported by the cylindrical drive surface of the drive wheel and the drive wheel is not entrained when the drive lever is returned to the initial position. The coupling element comprises expansion cams that can be tilted about an axis spaced apart from the drive axis. The expansion cams expand the actuation lever which is linked with the spring element in such a manner that the spring element which is supported by the cylindrical drive surface of the drive wheel is expanded.
Abstract:
An anti-pinch system of a vehicle closure includes a detection system for detecting pinching and a clutch to disconnect the vehicle closure from a closure driving mechanism following detection of pinching by the detection system. The closure drive mechanism can be disengaged to prevent an increase in pinching during the time required to reverse the movement of the closure driving mechanism.
Abstract:
A dual rack and pinion system is provided for a window lift mechanism. The window lift mechanism includes improved window brackets for simple mounting to a window. A modular frame design is provided to improve assembly of the window lift mechanism into the door of a vehicle. An improved assembly method is provided for the dual rack and pinion system. The system is also provided with a smart motor and incorporates resilient shock absorbers in the dual rack and pinion gear train to allow more time for the smart motor to detect and react to an obstruction in the window.
Abstract:
A braking system for a vehicle manual window-lifting mechanism prevents a window from dropping as a consequence of vibrations and minimizes angular play in a crank shaft. The system includes a helical spring that assists the crank shaft and that has a geometry modified from its conventional design. An included angle between the radial side pieces at which the winding ends terminate is an acute angle. One of the side pieces is coupled inside a radial hollow of the crank-driven shaft itself. The other side piece is located between the crank shaft and the drum, which rotate relative to each other. As a result, instead of the usual 40° or 45° of free play, the invention allows a maximum free play of only 10° to 15° in the crank shaft.
