Patent number: 6367123Abstract: A hinge and linkage system comprises a four-link system wherein first and second links are respectively connected to vehicle body and closure members, and an additional pair of links interconnect the first and second links. An expansible gas strut also interconnects the first and second links. In accordance with the invention, an expansible spring-biased plunger mechanism is mounted upon one of the additional links so as to operatively engage and be axially compressed by the second link and the closure member when the closure member is disposed at its latched position. When the closure member is unlatched, the spring-biased plunger mechanism initially partially elevates the closure member toward its open position whereupon the expansible gas strut can continue the elevational movement of the closure toward its open position.Type: GrantFiled: August 15, 2000Date of Patent: April 9, 2002Assignee: Illinois Tool Works Inc.Inventors: Jonathan Paul Anthony Cheal, Andrew Proffitt

Patent number: 6296142Abstract: A counter balance assembly for a lid assembly comprising a spring inside a housing assembly. The counter balance assembly is mounted to a lid, whose displacement generates an external force substantially along a longitudinal axis of the spring. A restoring force is generated by the spring to counteract an inertia force arising from the lid displacement.Type: GrantFiled: June 7, 1999Date of Patent: October 2, 2001Assignee: Applied Materials, Inc.Inventor: Son T.

Patent number: 6263542Abstract: A hinge assembly and methods for mounting a hatch relative to a port defined in a cover of a vacuum chamber to close and open the port. A torsion rod mounted between the port and the hatch is in torsion when the hatch is in a closed position relative to the port, assisting port-opening motion. A sleeve surrounds the rod and is movable with the hatch. Friction hinge structures between the cover and the sleeve, and between the hatch and a second sleeve are in a friction-engaging relationship with the corresponding sleeve. Each friction hinge structure provides high resistance to relative motion between a friction spring and the corresponding sleeve. During the port-opening motion of the hatch the friction springs provide low resistance to such relative motion. The hinge structures provide tolerance resistance and vacuum compliance by allowing relative movement between a hinge mounting plate and the hatch.Type: GrantFiled: June 22, 1999Date of Patent: July 24, 2001Assignee: Lam Research CorporationInventors: Dean Jay Larson, Thomas R.

Patent number: 6260236Abstract: A resilient member, useful in a back checking arrangement, is provided as a body of resilient material having a surface engageable by an outside member such as a portion of a sliding mechanism in a door closer. The body is compressible when engaged by the outside member with a sufficient force. The body has at least one reservoir chamber therein, for receiving a liquid, such as hydraulic fluid, with a communication passage leading from the chamber to the surface to provide fluid communication between the chamber and an exterior of the body. Additional communication passages from the chamber to the exterior of the body may be provided as well. When the body is engaged by the member, the body, chamber and passage are compressed, thus causing the liquid in the chamber to exit the body through the compressing passage. This increasingly restricts the flow of liquid through the passage and increases the force of operation.Type: GrantFiled: October 30, 1998Date of Patent: July 17, 2001Assignee: Jackson Corp.Inventor: George F. Toledo

Patent number: 6230364Abstract: A hinge mechanism for assisting the lifting of a trunk lid of a vehicle comprises a V-shaped leaf spring (12) mounted on a first hinge part (2) attached to the vehicle body, and a roller element (32) mounted on a second hinge part (4) attached to the lid. A compressible gas strut (38) may be connected directly between the lid and the body; alternatively the strut may be connected between the first and second hinge parts, (2, 4) so that the resulting sub-assembly can be mounted directly to the lid and body on the vehicle assembly line. The hinge mechanism assists in initially lifting the trunk lid so that the gas strut (38) is disposed in an advantageous leveraged position at which it can continue the lifting movement of the trunk lid.Type: GrantFiled: October 9, 1998Date of Patent: May 15, 2001Assignee: ITW LimitedInventor: Jon Paul Anthony Cheal

Patent number: 6167977Abstract: A work vehicle having a novel hood coupling apparatus is disclosed. The work vehicle includes a frame provided with a compartment and a hood. The hood is coupled to the frame by at least one hinge and at least one latch. The latch includes a stationary portion associated with the frame and a movable portion associated with the hood, and the hinge includes a first portion associated with the frame and a second portion associated with the hood. The latch is configured for the stationary portion to engage the movable portion in a particular location when the hood is closed, and the second portion of the hinge is configured to assume an approximate position with respect to the first portion of the hinge, and thereby to the frame, upon engagement of the latch, the latch thereby aligning the hood and the second portion of the hinge to the frame when engaged. The work vehicle may also include a hood biasing device and a hood positioner for controlling the amount of opening of the hood.Type: GrantFiled: January 15, 1999Date of Patent: January 2, 2001Assignee: Case CorporationInventors: William H.

Patent number: 6092264Abstract: A mechanism (10, 100) is disclosed for deploying a mechanism, such as an air foil or antenna (14, 102, 104) which utilizes a pivot axle (16) and a torsion spring (18) to pivot the erectable surface to the erected position. A locking pin 22 can be provided to lock the erectable surface (14) in the erected position. In one embodiment, a wing (102) and a control fin (104) can be deployed about a single axis.Type: GrantFiled: November 13, 1998Date of Patent: July 25, 2000Assignee: Lockheed Martin CorporationInventor: Johnny E.

Patent number: 5967392Abstract: A truck cargo bed utility box blow molded of high density polyethylene which complements the styling of many truck bedliners. The utility box incorporates a mounting system for a central pneumatic spring which holds the lid of the box open. The mounting system consists of a bracket mounted to a wall forming part of the storage bin and a bracket on the bin lid. The lid bracket and the bin bracket extend to and engage with a hinge pin which joins the lid to the storage bin. The brackets are constructed of sheet metal and are mechanically joined by the hinge pin. The loads imposed on the lid and bin wall by the air spring are distributed through the hinge pin. The bin bracket is also attached to a metal rim which surrounds the opening into the box to provide load distribution. The metal rim provides a distortion resistant structure to which locking hasps can reliably latch. By distributing the loads imposed on the plastic lid and plastic bin distortion of the plastic is prevented.Type: GrantFiled: April 22, 1997Date of Patent: October 19, 1999Assignee: Penda CorporationInventors: Karl A.
