Abstract:
The invention relates to a device for automatically actuating a vehicle door (1), in particular a side door or a tailgate of the motor vehicle. Said device comprises a control device (12) and a drive (4;4null) that consists of a motor (5) with a gearing (6) connected downstream and at least one transmission element (8;20) located between the gearing (6) and the vehicle door (1). The aim of the invention is to facilitate the manual actuation of an automatically actuated vehicle door (1) that is in an open position. To achieve this, a load sensor (10) is mounted on the drive (4). When a predetermined load on the open vehicle door (1) has been reached, said sensor generates a control signal, which is fed to the control device (12) for activating the motor (5), or for decoupling a coupling (18) that is located between the gearing (6) and the transmission element (8;20), the load on the open vehicle door (1) being produced e.g. by a corresponding manual pressure on said vehicle door (1).
Abstract:
A device for opening and closing a pivotally mounted door leaf (2) or the like comprises an actuator, which is displaceably and/or rotatingly arranged in a housing (10) and connected to the door leaf and which, during displacement rotation, actuates said door leaf, and a drive motor (27) which is connected to the actuator for providing displacement/rotation thereof.
Abstract:
A supporting and sliding system for a piece of furniture door comprises a supporting and sliding assembly (13) to be fastened to the door for running, by means of a grooved wheel thereof (16), on a rail (14) which is designed to be secured to the piece of furniture. Present along the rail (14) is an undercut (17) under which a locking end (18) of a constraint element (19) projecting from the sliding assembly is positioned, which constraint element prevents the wheel from lifting from the rail to such an extent that derailment of the wheel from the rail should be caused. Advantageously, the constraint element (19) is of a resilient type and an operating lever (22) enables it to be moved away from its locking position when the assembly (13) is required to be removed from the rail (14).
Abstract:
An overhead door safety sensor mounting bracket allows overhead door safety sensors to travel beneath the leading edge of an overhead door for substantially the full travel path of the overhead door as the overhead door closes. The mounting brackets attach to the bottommost roller axles of the overhead door on opposite lateral sides of the overhead door. As the overhead door approaches a closed position, the mounting brackets for the overhead door safety sensors rotate about the bottommost roller axles of the overhead door. The safety sensors are rotated up above the ground so that neither the safety sensors, nor the mounting brackets touch the ground.
Abstract:
Apparatus for guiding displaceable elements. The apparatus of this invention serves for guiding sliding elements, particularly doors, windows, dividing walls, shutters and coverings, that are slidably journalled on an upper side thereof in a first guide and are guided on a lower side thereof with an additional guide which is in turn connected with the floor or a side wall, with the additional guide including at least one elastic element which is adapted for direct force transfer or force transfer via transfer means, so as to press against the underside of the sliding element, so that the underside of the sliding element is retained by the additional guide free from play, thereby avoiding objectionable noises, both at rest and during displacement of the sliding element.
Abstract:
A quick release hinged support or bracket for coupling two cooperating objects together comprises a pair of plates each having opposed side walls and openings for mounting to the objects and further comprises retractable coupling members for hingedly coupling the two plates together. The retractable coupling members allows a user to quickly separate the plates of the hinged support and the two cooperating objects so that the user can conveniently and substantially clean the two objects such as a lid or cover attachable to a container or an appliance. The hinged support allows the user to quickly separate the two objects without having to use a tool.
Abstract:
A van door slidable in tracks (16, 18 and 20). An operating module is mounted inside the van adjacent center track 18. A front cable attached to drive pulley (144) extends through guide assembly (54) to hinge and roller assemble (26). A rear cable attached to drive pulley (136) extends through guide assembly (56) to hinge and roller assembly (26). The drive pulleys (136 and 144) each have a large diameter spiral cable groove (164), a small diameter cable groove (208) and a transition cable groove (210). A motor rotates the drive pulleys. The small diameter cable grooves drive the door when the door is in the forward portion of the tracks. The large diameter spiral cable grooves drive the door when the door is in the center and rear portions of the track. Fixed idler rollers (226 and 254) are positioned relative to the cable drive pulleys to insure that the total cable in the continuous cable loop is substantially the same when the cable is driven by the small diameter cable grooves as when the cable is driven by the large diameter spiral cable grooves. A cable tension system (220) maintains cable tension. A slack cable take-up pulley (174) on the drive pulley (136) takes up slack cable to set cable tension and is then locked in position.
Abstract:
An automatic sliding door in which a main drive moves at least one door panel to open and closed positions. An electromagnetic clutch is located between the main drive and the door panel for the purpose of disconnecting the panel from the drive and to open the door in event of a power failure. An auxiliary drive is connected to the door panel and stores energy received when the door panel is in a closed position, so as to drive the door to the open position when the clutch disconnects the main drive from the door panel in event of power failure. The auxiliary drive has a rubber cable actuated always with the door so that the auxiliary drive can be tested with every movement of the door panel.
Abstract:
One or more spring lock devices are included at the inner sides of a conventional garage door positioned to engage with the side door frame. The spring locks are actuated to the open position by operative connection, usually through tension lines to a garage door drive mechanism, which is connected to the garage door through a lost motion mechanism so that initial movement of the drive mechanism moves the spring lock devices and opens them before the garage door mechanism moves the garage door. For closing, the spring lock devices can be of the wedge striker type which will close and lock with the closing motion of the garage door or of a straight pin type, in which case the door is adjusted so that its balance mechanisms always biases the door toward the closed position when the door is near its closed position.
Abstract:
An arrangement for converting rotary motion into translational motion in which a motion-transmission device that is movable translationally, is divided into two strings that move longitudinally along their direction of motion. A driving motor provides rotational motion through a rotary drive. The strings are guided transversely and are positioned outside of a guide where they become separated. The strings, on the other hand, become united inside the guide, and this guide prevents the strings from being movable from each other laterally. The strings have teeth on sides facing each other in vicinity of the guide, and these strings have ends secured to an intermediate component in the guide, remote from the rotary drive. The intermediate component is common to both strings, and they become disengaged in vicinity of the intermediate component.
