Abstract:
A cable lift mechanism for a multi panel, overhead garage door includes a drum having a spiral groove comprised of two adjacent sections that are generally coaxial with the longitudinal axis of the cable drum. The groove or grooves in a first section adjacent the attachment end of the cable to the drum have a lesser radius than the remaining grooves of the second section of the drum which have substantially equal radii of greater diameter than the first section radii. As a consequence, initial torque associated with lifting of a garage door is increased to lift a heavier upper or top panel or panels of a multi-panel garage door.
Abstract:
A hinge for controlling the movement of a door on a refrigerator is disclosed, the hinge allowing the refrigerator to be installed flush to adjacent cabinets. The door translates and rotates in order to allow access to the refrigerator cabinet interior without contacting the adjacent cabinets.
Abstract:
A position detection arrangement for a functional element (1) which can be positioned motor-driven in a motor vehicle, a drive arrangement (2) being coupled via a drive train (3) to the functional element (1) and the functional element (1) thus being positionable by a motor (4), there being a measuring unit (5) which is assigned to the drive train (3) and which includes a sensor unit (6) and a gearing with a drive side and a driven side, the drive side being assigned to the drive train (3) and the driven side being assigned to the sensor unit (6). It is suggested that the gearing is realized as a tumble gearing (7) with a tumbler gear (8) and a ring gear (9).
Abstract:
The invention relates to a force supporting device (10) for providing a load-dependent supporting force, in particular for a lowerable overhead locker (12) in an aircraft. The device (10) comprises a bracket (20), whose one end is attached to a supporting structure so as to be pivotal about an axis (P) and whose other end is configured for connection to an object to which the supporting force should be applied. There is also a gas-filled spring (22), whose one end is pivotally articulated to the bracket (20) and whose other is pivotally articulated to one end of an oscillating lever (24), whose other end is pivotally attached to a bearing plate (18) and which can pivot relative to the bearing plate (18) between a first end position and a second end position. By means of an arresting device the oscillating lever (24) can be arrested at a plurality of positions in the region of its first end position to the second end position. A displacing device (46) serves to pivot the oscillating lever (24) between its first end position and its second end position as a function of a load determining device which interacts with the displacing device (46).
Abstract:
An opening and closing apparatus for vehicle lid includes a lower base adapted to be mounted on a body panel of the vehicle and arranged to an opening of an inner space of the vehicle, first and second hinge links rotatably connected to the lower base at each one end of the respective first and second hinge links, an upper base attached to the vehicle lid formed for closing the opening of the inner space and connected to each the other end of the respective first and second hinge links, a motor for providing a drive to the first hinge link, a drive transmitting member provided between the motor and the first hinge link for transmitting the drive from the motor to the first hinge link, a normally section torque transmitting mechanism provided between the drive transmitting member and the first hinge link for transmitting the drive to the first hinge link at a point of force reaction through the normally section torque transmitting mechanism after the drive transmitting member is rotated with a predetermined angle while the vehicle lid in a fully-opened state is under closing operation and a close-start section torque transmitting mechanism provided between the drive transmitting member and the upper base for directly pressing the upper base at a point of force reaction through the close-start section torque transmitting mechanism that a distance from a center point of the rotation of the upper base is longer than a distance of the point of force reaction through the normally section torque transmitting mechanism from the center point of the rotation of the upper base before the drive transmitting member is rotated with the predetermined angle while the vehicle lid in the fully-opened state is under closing operation.
Abstract:
A device for controlling a door operated by a motor includes an opening/closing mechanism that opens and closes the door, and a gear mechanism that includes a plurality of tooth units each of which has different mesh and that conveys a torque of the motor to the opening/closing mechanism. The tooth units include a low-torque tooth unit that convey a relatively low torque, and a high-torque-tooth unit that conveys a relatively high torque. The torque conveyed to the opening/closing mechanism is changed by selecting a tooth unit based on a position of the door at the time of starting an opening or closing operation of the door.
Abstract:
This invention relates to an overhead door closer with slide arm assembly having a toothed pinion that is eccentrically supported and presents a circular rolling curve, which pinion meshes with a toothed rack arranged at a piston. The invention concentrates on a particular embodiment of the rolling curve and of the teeth of the toothed rack in adaptation to a toothing of the pinion. Furthermore, the invention concentrates on an improved embodiment of the delayed closing operation in order to achieve an optimized movement pattern of the piston within the housing of the overhead door closer with slide arm assembly.
Abstract:
A method and system for controlling the descent of a moveable element pivotally attached to a rigid structure. The moveable element is pivotally attached to the rigid structure, and is then pivotally connected to a compressible strut, which is pivotally attached to a linkage pivotally connected to the rigid structure. The descent of the moveable element is controlled using a microcontroller and a motor attached to the linkage, and the control path for the linkage is selected based on a comparison of the angle between the linkage and rigid structure and the angle between the moveable element and the rigid structure.
Abstract:
A device for urging a door into a first position includes a spring apparatus (16) including a winding drum (22) having a conical outer peripheral surface (27) and a torsional spring (24) for imparting a relatively constant urging force to a cable 23 secured to the door in the direction of the first position.
Abstract:
A pivot-hung door drive system with an electro-mechanical or electro-hydraulic drive device that supplies the opening and closing moment required to open and close a connected pivot-hung door panel, whereby an electronic regulation/control system with at least one memory and at least one microprocessor, on the basis of sensor signals, controls the opening or closing moment by means of a gear wheel that is located on an output shaft, which gear wheel is connected by means of a linkage and an actuator arm with the pivot-hung door panel, whereby between the output shaft of the pivot-hung door drive system and the linkage or the actuator arm, there is a device that effects a change in the opening and closing moment over the angle of rotation of the pivot-hung door panel.
