Abstract:
A drive train for a pivotable flap of a motor vehicle includes a holding device which can hold the flap in at least one open position, a first element which can be driven by a drive motor, and a second element connected to the pivotable flap to pivot the flap in response to movement of the first element. When the second element is moved along a path of motion relative to the first element counter to a specific spring force, a sensor generates a signal indicating relative motion of the elements, and a control device releases the holding device in response to the signal, whereby the flap can be moved manually by applying a force counter to the spring force.
Abstract:
A push-out style window assembly including window hardware for frictionally retaining an open position of the window under typical loading conditions. A push-out style window assembly generally includes a friction hinge assembly including a track, a sash arm, a support arm, and a friction arm. The friction arm can include an adjustable and/or detachable slide enabling adjustment of a frictional resistance between the friction slider and the support arm. Using the friction arm, frictional resistance is provided so as to provide control both during opening of the window and in retaining the position of an open window.
Abstract:
A driving device for an adjusting system of a motor vehicle includes a transmission with a drive element rotatably mounted about an axis of rotation for introducing a torque, a driven element rotatably mounted about the axis of rotation for delivering a torque, and a wrap spring brake device for transmitting a drive-side torque introduced by the drive element to the driven element and for blocking a driven-side torque applied on the driven element. It is provided that the drive element and the driven element each are mounted on a stationary portion of the transmission. In this way a driving device is created, whose drive element and driven element can have low bearing tolerances and which in addition is optimized in terms of friction to provide a smooth operation.
Abstract:
A hold open rod is provided. The hold open rod includes an outer tube, a lock body connected to the outer tube, an inner tube, slidingly disposed within the outer tube and lock body, the inner tube having an outer surface, and a friction pad captured between the lock body and the outer surface of the inner tube. A method for damping movement of a telescoping rod is also provided. The method includes attaching the locking body to an outer tube, configuring the outer tube and the inner tube to move with respect to each other in a telescoping manner, fitting a damper between an outer diameter of an inner tube and a locking body, and fitting the damper to frictionally engage the outer diameter of the inner tube and the locking body.
Abstract:
Provided is an opening-and-closing mechanism that can be latched at a predetermined opening angle, wherein the latching can be disengaged with a small force in the opening direction whereas the latching is gradually disengaged in the closing direction. An opening-and-closing mechanism 1 includes a first supporting member 9 and a second supporting member 7 disposed relatively rotatable around a rotary axis; a plurality of protruding portions 15 provided on the first supporting member 9; and a plurality of depressed portions 23A, 23B, 23C, 23D, 23E, and 23F provided on the second supporting member 7 and engaged with the plurality of protruding portions 15, wherein, when the first supporting member 9 and the second supporting member 7 are in a plurality of predetermined relative alignments, some of the plurality of protruding portions 15 and some of the plurality of depressed portions 23A, 23B, 23C, 23D, 23E, and 23F are engaged, and wherein forces required for disengaging the protruding portions 15 and the depressed portions 23A, 23B, 23C, 23D, 23E, and 23F by rotating at least one of the first supporting member 9 and second supporting member 7 differ in a first rotation direction and a second rotation direction.
Abstract:
A vehicle tailgate movement assist mechanism including a tailgate configured to rotate between opened and closed positions, and a tailgate lever arm fixedly connected to a bottom area of the tailgate. A drive lever may be pivotally connected to the lever arm and to a bell crank at opposite ends thereof. The bell crank may be connected to a shaft of a rotary gear pivotally anchored to a vehicle body. A rotary damper may be anchored to the vehicle body and include a damper gear connected to a shaft thereof. The damper gear may be rotatably meshed with the rotary gear. Rotation of the tailgate from a closed to an opened position simultaneously rotates the lever arm to move the drive lever and the bell crank to thereby rotate the rotary gear which rotates the damper gear to actuate the rotary damper to reduce an opening speed of the tailgate.
Abstract:
An overhead door control system includes an input shaft drivably connected to an overhead door axle and a load brake shaft drivably connected to the input shaft. The control system includes a load brake which releases the load brake shaft in response to rotation of the input shaft. The load brake engages the load brake shaft in response to the rotation of the input shaft being driven to zero.
Abstract:
A spindle drive for a movable component includes a threaded spindle which is rotatable about a spindle axis; a spindle nut which engages the threaded spindle; and a transmission element which can be connected to the movable component, the transmission element being fixed against rotation about the spindle axis and being axially drivable by rotation of the spindle nut. An intermediate element, which is fixed against rotation relative to the spindle nut, extends axially with respect to the threaded spindle and is rotatable relative to the threaded spindle. A drive is connected to rotate one of the intermediate element and the threaded spindle; and the other of the intermediate element and the threaded spindle can be fixed against rotation.
Abstract:
Brackets for interrupting the opening of a multi-panel garage door and methods for their use, the brackets including a first plate having an inner face and an outer face, a pin located on the outer face of the first plate, and a protrusion associated with the first plate, the protrusion and pin defining a gap capable of accepting a garage door opening cable.
Abstract:
A closure mechanism C comprising a elongated push/pull member 1, a base part 2, a resilient element 4, such as a coil spring, a motion converting means 6, such as a rack-and-pinion gearing, comprising a rotary output element 6o and a rotary braking device 7, such as a centrifugal brake, comprising a rotary input element 7i directly or indirectly coupled to said rotary output element 6o at least during movement of the elongated push/pull member 1 towards said first position, so as to be rotated thereby. The elongated push/pull member 1 and the base part 2 are assembled to each other so that said elongated push/pull member 1 is guided in a translational motion relative to the base part 2 between a first and a second position. The resilient element 4 is placed between said first and base parts 1, 2 so as to urge the elongated push/pull member 1 towards said first position. The motion converting means 6 converts the translational motion of said elongated push/pull member 1 relative to said base part 2 into a rotational motion of said rotary output element 6o, which is transmitted to the rotary input element 7i, and the rotary braking device 7 brakes its rotary input element 7i with a variable braking torque which increases and decreases with the rotational speed of said rotary input element 7i.
