Abstract:
An emergency door closing device that can be installed upon existing doors and hinges to automatically close doors in the response to smoke and fire. The improvements incorporated therein include a hinge cam pivot member that attaches to an existing hinge member of a door and produces a moment force about the existing hinge member allowing a reduced force necessary to pivot the door into a closed position. Further, a novel spring, cam, and lever system is incorporated to activate the moment force to close the door.
Abstract:
A drive device for a flap of a piece of furniture including at least one actuating arm which is activated by a spring device and is intended for moving the flap. A pushing-out device can move the flap from the closed position the opening direction toward the open position over a first opening-angle range (M1). The spring device exerts substantially no force on the flap in the first opening-angle range (M1), and the spring device moves the flap in the opening direction only in a second opening-angle range (M2), wherein the second opening-angle range (M2) adjoins the first opening-angle range (M1) or, at most, slightly overlaps the first opening-angle range.
Abstract:
The invention relates to a drive mechanism having a drive motor and a drive element drivable by the drive motor. A first worm gear, which has a first worm gear shaft and a first worm wheel, and a second worm gear, which has a second worm gear shaft and a second worm wheel, are connected between the drive motor and the drive element.
Abstract:
An actuator device for automatically activating the vehicle door of a motor vehicle, in particular the tailgate, is disclosed. The actuator device includes an electromotive drive and a radially extending arm attached either to the vehicle door or to a vehicle bodywork, and set in motion by the electromotive drive, the electromotive drive having an electrical motor and a gearbox driven by the motor, characterized in that, the gearbox has a wobble mechanism.
Abstract:
An actuator for a flap on an item of furniture includes at least one actuating arm that is mounted to pivot between a closed position and an open position in order to move the flap, a spring device for acting on the actuating arm, and a transmission mechanism for transmitting the force of the spring device onto the actuating arm. An adjustment device allows the transmission mechanism to be shifted between at least two operating positions. In a first operating position, the spring device applies a closing force, in the direction of the closed position, onto the actuating arm which is in an opening position immediately upstream of said closed position. In a second operating position, when said actuating arm is in the aforementioned, immediately-upstream opening position, the spring device exerts a force which acts in the direction of the open position.
Abstract:
A spring winding device, a counterbalancing force adjustment device for a counterbalancing mechanism, and a method of adjusting an amount of force stored in a spring of a counterbalancing mechanism are provided. The spring winding device includes a support bracket, a worm gear, and a drive gear. The worm gear is rotatably coupled to the support bracket and includes a mount portion for coupling a first end cone thereto. The drive gear is rotatably disposed adjacent the support bracket and is drivingly engaged with the worm gear. A rotation of the drive gear causes the worm gear to rotate within the support bracket. The spring winding device does not require pretensioning using winding rods, maintains rigidity and alignment when a counterbalancing force is applied, and decreases a cost and a complexity of the counterbalancing mechanism.
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).
