Abstract:
An assembly for opening/closing doors including at least a first wing, a second wing and a mechanism adapted to move the wings from a closing position wherein they lie in a vertical plane, to an opening position wherein they are arranged facing each other and lying onto parallel and substantially horizontal planes, and vice versa. The passage from the closing position to the opening position and vice versa occurs through a synchronized and simultaneous rotary-translating motion of the wings. The mechanism includes first and second kinematic arrangements respectively adapted to move the first and second wings, the kinematic arrangements being separate and distinct, kinematically connected through a mechanism for synchronizing and changing the transmission ratio to impart a differential trajectory to the synchronized motion of the first wing with respect to the second wing during closing and opening.
Abstract:
A system of ejecting a sliding door of a closet, comprising a plurality of ejection assemblies and a connecting mechanism, which connects one assembly to the other. Each ejection assembly comprises a rail and a slidable member configured to slide along the rail, where the rail engages with a frame of the closet. The connecting mechanism allows synchronizing the ejection force applied upon the door at different locations of the door, by connecting the ejection assemblies through the connecting mechanism. This configuration allows ejecting and retrieving of the door outwardly and inwardly by sliding the slidable member of each assembly along the rail.
Abstract:
A drive assembly for a closed loop cable system in which a flexible driver member drives a door or the like back and forth has the flexible drive member wrapped around and driven by a drive pulley. The drive assembly includes a motor unit having a motor shaft that rotates about a drive axis for rotating the drive pulley about a pulley axis, and a tensioning mechanism for adjusting the position of the pulley axis with respect to the drive axis responsive to tension in the flexible drive member.
Abstract:
A driving system for a garage door includes a track having an end fixed on an inside of a wall and has an open side that faces upward. A driving assembly is movably received in the track and driven by a motor. The driving assembly includes a connection member to which two ends of a power transferring member are connected. A U-shaped member is movably engaged with the track from an underside of the track and two sides of the U-shaped member are connected to the driving assembly. A link is pivotably connected between the U-shaped member and the garage door. The power transferring member reeves a gear which is rotatably connected to the track and the motor has a driving shaft which is conveniently extended through an opening of the track and engaged with an engaging hole of the gear.
Abstract:
The invention relates to a curved vehicle door having a correspondingly curved windowpane and a correspondingly curved function carrier on which all of the add-on parts and door coverings are held and which can be used as protection for the occupant in the nulllacunanull or in a militant assault, the function carrier being provided in each case along lines at least in two parallel planes with intersecting stiffening sections and advantageously being constructed in a sandwich-like manner from at least two shell bodies with longitudinal and transverse stiffening sections within a continuously closed frame, the outer shell body of which has at least two parallel grooves for accommodating a window lifting and lowering device which is matched to the curvature of the vehicle door.
Abstract:
A door closer or operator includes a pivoting pinion on the door closer housing for transmitting door motion, and a cam connected thereto. A connecting member extends along a spring and engages the peripheral edge of the cam. Rotation of the cam causes a change in length of the portion of the connecting member between the position tangent to the cam peripheral edge and the spring second end to expand or compress the spring, resulting in a force transmitted along a longitudinal axis of the connecting member as a result of spring deflection. The cam peripheral edge has a profile with a varying radial distance between the cam axis and the connecting member at the position tangent to the cam peripheral edge such that the radial distance is changed as the spring expands or compresses to maintain a desired constant torque about the axis of the cam and pinion.

Abstract:
A control system for controlling an adjustment device which is operated by electric motor in a motor vehicle includes an indirect anti-trapping system for detecting a trapping situation between an adjustment element, which is moved by the adjustment device in an adjustment movement along an adjustment path, and a vehicle element. The anti-trapping system stops or reverses the adjustment movement of the adjustment element if a defined threshold value for a mechanical running parameter—which results from the adjustment movement is exceeded. The anti-trapping system operates with an analysis unit for analyzing the adjustment movement of the adjustment element, wherein the control system is configured and embodied in such a way that by means of the analysis unit, in an analysis mode, the running parameters of the adjustment device can be checked for mechanical functional faults of the adjustment device.
