Abstract:
A door hinge and a method of its use is provided which is suitable for use with glass shower screen doors. The method involves cutting a pair of circular cut-outs at a side edge of the door near the top and bottom of the door respectively. After toughening of the cut-out portions of glass, a hinge in accordance with this invention is mounted in each cut-out portion. The hinges each have a first arm which has a circular door mounting portion of substantially the same diameter as the cut-outs which are located in the cut-outs. The hinges each have two clamping parts, one part is fitted to abut with one face of the door, and the other part is fitted to abut with the other face of the door. Each part is fitted to immediately surround the respective cut-outs. The hinge then has screw holding means which holds the parts together and clamps the door. The second arm of the hinge can be mounted directly to a frame member, such as a jam member or to a further glass panel. In the case where mounting is to a further glass panel, the mounting can be by similar circular cut-outs, and by the second arm having a similar circular door mounting part, and clamping parts. By having circular cut-outs, it makes the cutting of the glass door less complicated than providing square shaped cut-outs used in the past.
Abstract:
A powered drive assembly for positioning various slidable components within a vehicle interior. The powered drive assembly includes a motor assembly operably coupled to a flexible flocked drive cable which is supported for rotation within a housing. The flocked drive cable provides a helical surface. Specific coupling members are adapted to engage the helical surface and operably couple the drive cable with the slidable component. For example, in one preferred embodiment a coupling bracket operably couples the flocked drive cable to a slidable window assembly of the type used in the rear opening of a pick-up cab for opening and closing the window. In a second preferred embodiment, the coupling member operably couples the drive cable to a curtain assembly located within the interior of an over-the-road truck cab for opening and closing the curtain. The drive assembly further enables the motor assembly to be remotely located from the housing and coupling brackets, thereby facilitating in packaging of the powered drive assembly within the confines of the vehicle interior.
Abstract:
A modular sliding window assembly in a motor vehicle has two glazing panes, typically a sliding subassembly incorporating two vertically mounted transparent panes, which are slidably mounted in a circumferential frame slightly to the interior of, substantially parallel to and between two fixed panes. The sliding panes are mounted for sliding laterally back and forth between their open and closed positions. A motor and drive drum apparatus for powered operation of the window assembly is mounted to the vehicle body at a location remote from the frame. First and second cable fasteners are mounted to first and second sliding panes, respectively, and first and second cable guides are provided to guide a drive cable. The drive cable extends from the drive drum to the second cable fastener through the first cable guide, from the second cable fastener to the first cable fastener through the second cable guide, and from the first cable fastener to the drive drum through the first cable guide.
Abstract:
A brake and clutch assembly mounted on an electric motor's drive shaft comprises, in succession and outwardly from the motor, a brake pad, a drive disk, a clutch plate, a pulley, a compression spring and an end cap. The drive disk includes a sleeve with the clutch plate and the pulley being slidably mounted thereon. A pin extending diametrically through the shaft lies in a diametrical V-shaped recess defined in the drive disk. The spring biases the pulley, clutch plate and disk drive towards the brake pad thereby frictionally retaining the drive disk thereagainst when the motor is not operating and preventing the components from rotating. When the motor is started, the pin climbs out of the bottom of the recess by pushing the drive disk against the spring's force thereby axially displacing slightly the disk drive away from the brake pad such that the pin rotates the drive disk which frictionally drives the clutch plate and the pulley. Resistance applied against the rotation of the pulley causes the clutch plate to slip thereby allowing the pulley to stop while the clutch plate, the drive disk and the motor shaft continue to rotate, thus preventing damage to the motor. The friction forces between the clutch plate and the pulley are insufficient to stop the clutch plate and thus the drive disk and the motor shaft if the pulley is forced to stop rotating.

An actuator device for an electric window winder (101) having an electric motor (104) and a window displacement actuator element (112) which is displaceable with respect to a frame (102) of the device under action of the electric motor (104). An electronic unit (27) for drive and control of the electric motor (104) has power elements and is housed in a first portion (120) of the frame (102), and the electric motor is housed in a second portion of (107) of the frame (102). The first and second portions (120, 107) of the frame (102) are formed by a single one-piece body part of the frame, and the power components of the electronic unit (27) are in direct thermal contact with the first portion (120), which is formed of a thermally conductive metal material for the dissipation of heat from the power components.
Abstract:
A hinge, preferably for hinging a door or flap to a carrying wall of a furniture corpus, comprises a cup-shaped hinged hinge member and a hinge bracket, which is articulatedly connected to the hinge member by two links and is adapted to be mounted on the carrying wall by a carrying plate. One of the links is extended in length beyond the pivot pin by which the link is connected to the hinge bracket, and that extended length portion of the link is so connected by a coupling link or by a guide slot to a pin which is mounted on the carrying plate or on an intermediate plate, which is adapted to be connected to the carrying plate, that the hinge bracket will be pivotally and longitudinally displaceably held on the carrying plate or on the intermediate plate by pin-slot guides during pivotal movement of the one link.
Abstract:
An electric motor drive unit for driving a worm wheel such as for vehicle window regulator applications wherein a casing housing a rotatable armature utilizes a synthetic plastic end cap at one end, and a worm wheel housing constitutes the motor end cap at the other end. A worm shaft rotatably mounted within the wheel housing upon its own radial and thrust bearings interconnects to the motor armature through a self-aligning drive element extending through a thrust bearing defined in the worm wheel housing. The brush holders for the motor are homogeneously formed of synthetic plastic material upon the associated end cap, and the armature utilizes an inexpensive self-aligning bearing mounted within the end cap and worm wheel housing.

Abstract:
A split-tubular track structure to receive carriage means for suspending sliding doors from a wall of a building and brackets for mounting the track on a building wall above a door opening. Preferably the brackets have fastening flanges parts of which overlie a horizontal surface of the building wall so as to be mounted by nails driven through the horizontal surface, track flanges on the brackets have depending headed studs which slidably engage a line of keyhole slots in the upper part of the track for quick mounting of the track on the brackets, and means are provided for preventing the track from moving relative to the brackets. For outdoor use the bracket track flanges extend downwardly and outwardly from the track, and a continuous shield has its upper edge portion secured to the building wall and its lower edge portion folded around the outer ends of the track flanges. Firm contact between an intermediate portion of the shield and the tops of the track flanges bows the shield to damp vibration and to give the shield a smooth surface appearance.
