Patent number: 6324788Abstract: A powered window regulator for use with a horizontally sliding window assembly may be disconnected from a sliding pane to permit manual operation of the window. The regulator has a tubular guide rail mounted adjacent and parallel to the lower edge of the window assembly by pivot brackets which engage the respective ends of the guide rail such that the guide rail is rotatable about the pivot brackets. A carrier block slides within the guide rail, and a portion of the block extends out through a longitudinal slot extending along the length of the guide rail to engage a pane attachment affixed to the sliding pane. The carrier block is moved reciprocally along the guide rail by a motor-driven cable to slide the sliding pane between open and closed positions. Rotation of the guide rail about the pivot brackets through approximately ninety degrees moves the carrier block between an upright position wherein it engages the pane attachment and a depressed position wherein it is disengaged from the pane attachment.Type: GrantFiled: February 4, 2000Date of Patent: December 4, 2001Assignee: Hi-Lex CorporationInventors: Kevin Koneval, Jeffrey W.

Patent number: 6321490Abstract: A mechanically interlocking belt weatherstrip for a motor vehicle. The weatherstrip is formed by three separate components: a cover, a body and a sealing lip. The weatherstrip may be made from separate, all-extruded components, or may be a made from a combination of molded and extruded components. The weatherstrip is formed by snapping the body and the cover snap together to hold the sealing lip securely in place. Because the cover can be easily interchanged with a different cover, the cover can be made to include properties, such as color and gloss, desired by a particular motor vehicle manufacturer while the remaining components remain unchanged. Thus, the weatherstrip allows versatility of the selection of the separate components to meet the individual style and functional needs of a particular motor vehicle design.Type: GrantFiled: October 1, 1997Date of Patent: November 27, 2001Assignee: GenCorp Inc.Inventor: James Randall Vance

Patent number: 6318024Abstract: A system for servicing an overhead door having a spring counter balance mechanism, an operator and a directional control system. The servicing system includes a counter, information cards, and contact cards. The counter includes a counting device and a numeric display. The counting device records the number of full cycles of the springs used in the counter balance mechanism measured from the fully closed position of the door. The numeric display shows this number of full cycles. An inspector of the door compares this number to the cycle failure specification for the springs used in the counter balance mechanism listed on the information cards. If replacement or attention is required, the inspector uses the contact cards to inform the appropriate parties that the door is not functioning properly or that the springs require attention.Type: GrantFiled: December 10, 1999Date of Patent: November 20, 2001Assignee: Fallon Safety Systems, Inc.Inventors: Joseph J.

Patent number: 6314680Abstract: A louvre shutter adapted to be assembled from elements forming a kit. The elements are so adapted that the shutter dimensions can vary, enabling the shutter to be installed within a window frame that falls within a predetermined range of sizes. The side rails of the shutter incorporate elongate channels for receiving elongate support members. The support members have a plurality of apertures that journal elongate pinion gears projecting from the louvres. The combination of the support rails, louvres, and pinion gears forms a sub-assembly that can be received within the side rails and top rails of the shutter frame. The support members include channels that receive gear racks. The pinion gears mesh with the gear racks enabling synchronous rotation of the louvres. The pinion gears perform the additional function of operating as spindles for the louvres. The dual functionality of the pinion gears reduces the complexity of component parts in the kit and facilitates assembly.Type: GrantFiled: June 24, 1997Date of Patent: November 13, 2001Assignee: Nomad Handicrafts Pty Ltd.Inventors: David Buckwalter, Ian Plummer

Patent number: 6311432Abstract: A safety device for center pivot doors which prevents the crushing of fingers between the door and the door frame comprises a rigid elongate barrier member secured on one or both sides of the door which sweeps the zone between the door and the frame as the door pivots, and which is shaped substantially to fill the gap between door and frame when the door is fully opened. The barrier member is preferably adjustable by being made in two interengageable parts. The gap between door and frame can be further reduced by providing elongate shielding strips secured to the frame, one on each side of the door.Type: GrantFiled: March 3, 1997Date of Patent: November 6, 2001Inventor: Paul Lennard Watson

Patent number: 6308463Abstract: A door having a core made from a composite panel material such as medium density fiberboard or particleboard is provided with a plurality of dowels which are secured, such as by an adhesive, within openings extending into the core. The dowels and openings are positioned in alignment with the screw holes in the hinges which mount the door to a jamb or cabinet. Screws or other fasteners extend through the screw openings in the hinges and are secured within the dowels. The dowels permit conventional wood screws to be used to mount the hinges to the door and improve the screw holding capability of the door. The dowels also eliminate the need to use edge banding for screw holding purposes and thereby eliminate the problems associated with the joint formed between the edge banding and the core material.Type: GrantFiled: April 18, 2000Date of Patent: October 30, 2001Assignee: The Maiman CompanyInventor: Timothy J.

Patent number: 6308461Abstract: A method and system for detecting the presence of an object caught between an automotive window and its respective frame is provided. The window opens and closes via a regulator driven by an electric drive motor. A force is sensed at an interface between the window and the regulator proportional to a force exerted on the window. This force is compared with a predetermined value, and if the sensed force exceeds the predetermined value, an object caught between the window and its respective door frame is detected.Type: GrantFiled: September 8, 1999Date of Patent: October 30, 2001Assignee: Meritor Light Vehicle Systems, Inc.Inventors: Charles Hopson, Timothy Davies, Christos Kyrtsos, Joseph Tyckowski, Pascal Bonduel, Francois Breynaert

Patent number: 6305123Abstract: In a first embodiment, a vehicle window obstruction system incorporates a conductive coating placed on the window. Such coatings are known for use in defrost systems. A voltage source is connected to the conductive coating, such that an electrical charge is placed across the window. Electrical characteristics of the charge are monitored, and compared to expected values. In the event that an obstruction is encountered, the monitored values will differ from expected values, and a control can indicate the presence of an obstruction. Alternatively, the signal could be a high frequency signal such as a sound signal which would be varied when the window contacts a human obstruction.Type: GrantFiled: September 17, 1999Date of Patent: October 23, 2001Assignee: Meritor Light Vehicle Systems, LLCInventors: Timothy Davies, Charles Hopson, Pascal Bonduel, Francios Breynaert, Christos Kyrtsos, Joseph Tyckowski

Patent number: 6295772Abstract: The modular masonry step and deck assembly consists of a plurality of like-shaped risers and a plurality of like-shaped treads that enable the assembly to have a variety of shapes, sizes and heights to provide a custom fit to a variety of buildings, mobile homes or trailers. The risers are dry stacked in a multi-tier, multi-column, multi-row arrangement to form a base of the assembly. An inwardly expanding groove is formed in each corner of each riser. When aligned flush with adjacent risers and dry stacked one atop the other in a stacked bond arrangement, the groves form a continuous vertical channel. A semi-flexible locking key is formed inside the channel to secure the risers together, but accommodate movements caused by the freezing and thawing of the ground. Four differently shaped treads are used to form the walking surface of the step and deck assembly. Each tread shape is used to form a specific portion of the walking surface.Type: GrantFiled: April 30, 1999Date of Patent: October 2, 2001Assignee: Bend Industries, Inc.Inventor: Robert L. Whitson
