Abstract:
A power window assembly in a vehicle includes a slidable window pane mounted to the vehicle for movement in a first lateral direction to an open position and in a second lateral direction to a closed position. The power window assembly further includes first and second mounting brackets securely attached to the window pane and each having a pocket therein. The power window assembly also includes a power drive mechanism for selectively moving the window pane between the closed position and the open position. The power drive mechanism includes first and second connector arms each laterally coupled to the first and second mounting brackets, respectively. The connector arms each have an upper portion seated in the pockets of the respective mounting brackets by slip-fitted insertion therein and are vertically slidable relative the pockets to adjustably connect the window pane to the power drive mechanism. Thus, the connector arms of the power drive mechanism vertically float relative the window pane during movement of the window pane between the open position and the closed position.
Abstract:
This invention provides an existing garage door locking system with a motorized unlocking system that will unlock the garage door prior to motorized opening, but maintain garage accessability and security with the existing garage door locking system if a power or motorized garage door system failure occurs.
Abstract:
An overhead door assembly designed particularly for use with vehicles such as railroad cars is disclosed. The door assembly is made up of an overhead door, vertical guide members for guiding the overhead door in the vertical direction and horizontal guide members for guiding the door in the horizontal direction. A motor is provided for driving the door between an open and a closed position. According to the invention, the door is first guided to a position directly in front of the door opening, but slightly spaced therefrom. The door is then moved horizontally in a plugging movement so as to securely close off the door opening.
Abstract:
A device (16b) for tilting windows, doors, ventilation hatches, or similar closures open, with a motorized transmission-activating mechanism (12b) and a transmission (14b) comprising two back-to-back chains that curve in opposite directions.
Abstract:
Given is a formed partition made of displaceable wall elements that are suspended, by means of carrier studs, on two carrier members that are displaceable in guide rails, and movable along their perpendicular interfaces in sealing contact against one another and/or against terminal elements. Situated on the horizontal interfaces of the wall elements are sealing strips that are capable of being extended in contact against the floor and/or the guide rails or the ceiling of the room. On one of the wall elements, one of the carrier studs is journaled in horizontally-displaceable fashion toward the other carrier stud. In order to be able to execute a simple and rapid transport of the wall elements, even diagonally, running in the guide rail is a drivable endless element to which are fixed, at a predetermined interval apart, two followers. Disposed on the carrier members are vertically-extendable follower pins, which, in the extended position, come into engagement with the followers and are then transported by the endless element along the guide rail.
Abstract:
A sliding window assembly for moving a window between a cavity defined by a structure having an outer surface, and a space located above the cavity comprises a first motor for selectively moving the window between the cavity and the space and a second motor for selectively moving the window between a first position substantially aligned with the cavity and a second position substantially aligned with the outer surface. First sensors indicate when the window is substantially entirely within the cavity and when the window is substantially entirely within the space. Second sensors indicate when the window is in the first position and when the window is in the second position. In one embodiment of the invention, third sensors indicate when the window is positioned for the second motor to move the window between the first and second positions. A programmable logic controller is connected to the sensors for appropriately controlling the motors.
Abstract:
A sliding door in a van is mounted on tracks for sliding movement between open and closed positions. At the closed position a weather strip is compressed and a door latch is latched. A cable is attached to the door and routed through the vehicle body via pulleys so that pulling the first cable end opens the door and pulling the second cable end closes the door. A motorized drive mechanism includes first and second reels mounted concentrically and having the cable ends wrapped respectively about the reels in opposite directions. A motor drives in one direction rotating the first reel to open the door and is reversible to rotate the second reel to close the door. Each of the reels has a large diameter portion for winding the cable to provide relatively high speed and low force door movement over the greatest portion of travel and a small diameter portion for winding the cable to provide relatively low speed and high force movement of the door during the lesser portion of travel of the door closest to the closed position. The reels have cable set grooves to receive the cable and a spiral ramp groove to connect the large and small diameter portions. A tension retaining spring acts between the two reels to always maintain the cable under tension.
Abstract:
The invention relates to an automatic remote controlled opening device which may be used to open and close doors, windows or similar closure systems. The opening device includes a receiver to detect control signals generated at a remote location from the device. The control signals are then utilized to effect selective operation of a mechanical system coupled with the closure system for opening and closing thereof. The mechanical system enables smooth and efficient automatic opening and closing, but does not inhibit manual operation of the door or the like. Control circuitry associated with the device enables various functions to be performed for selective operation of the device. The device may also be provided with a stored energy source of power such that it can be retrofit for use with an existing closure system. Auxiliary control of the device enables opening or closing in response to an emergency situation or other circumstances.

Abstract:
A power supplying system for supplying power to a self-driving closure device in which a driving source for driving the closure device for opening and closing an opening moves together with the closure device includes a lead wire having one end connected to a power source and the other end connected to the driving source. The side of the lead wire connected to the power source is supported at a midpoint between the positions of the upper and lower limits of movement of the driving source, while the side of the lead wire connected to the driving source is supported in such a manner as to move together with the driving source. The lead wire is thus made to swing in conjunction with the movement of the driving source so as to supply power to the moving driving source. A guide shaft is provided along the direction of movement of the driving source, and a helical portion formed in the lead wire is extended or shrunk along the guide shaft so as to supply power to the moving driving source.
