Patent number: 6908255Abstract: A clamping flexure for use in a vacuum employs a spring-loaded shaft that pulls an object being supported against a support piece, including a mechanism, passing through the vacuum vessel, for releasing the spring tension during adjustment, the shaft being sufficiently compliant that restoring force after adjustment is less than a threshold value so that displacement of the shaft does not impress a force on the object being supported that returns it toward its position before adjustment.Type: GrantFiled: June 25, 2003Date of Patent: June 21, 2005Assignee: International Business Machines CorporationInventors: Rodney A. Kendall, Lonn E. Moore, David J. Pinckney, Richard A. Rieland

Patent number: 6908249Abstract: A lock for securing first and second telescoped pole sections includes a base defining a through-bore for receipt of an end of a first pole section. A neck projects from the base and a collar is connected to the neck. The collar defines an opening aligned with the bore of the base. The collar receives a second pole section that is telescoped into the first pole section. A fastener is connected to the collar and a threaded end thereof projects from the collar. A lever control member is mated with the threaded end of the fastener and is movable to selectively radially constrict the collar. The fastener is rotatable relative to the collar but is frictionally engaged with the collar to prevent its unintended rotation. As necessary, the fastener is rotated relative to the collar to adjust the amount that the lever is advanced thereon.Type: GrantFiled: October 11, 2001Date of Patent: June 21, 2005Inventor: Erwin Tomm

Patent number: 6516684Abstract: A locking mechanism includes a seat having four comers each having a tube foamed thereon. Four guide posts of a base of a shaper extend through one of the tubes of the four corners, respectively. Each guide post is clamped by a respective tube when in a locking position. The seat further comprises two longitudinal through-holes each for receiving a connecting rod. Each connecting rod has two ends respectively operatively connected to two of the four tubes of the seat. One of the connecting rods is moved to urge each tube to the locking position. The connecting rods are linked together to thereby allow synchronous movement of the connecting rods. Thus, when one of the connecting rods is moved, all of the lugs are moved to the locking position to thereby synchronously clamp the guide posts of the base.Type: GrantFiled: July 9, 2001Date of Patent: February 11, 2003Inventor: Lee-Cheng Chang

Patent number: 6499810Abstract: A locking quick-release bike hub skewer for securely engaging an axle of a bike includes a security lock for preventing theft. A cam member is housed within a quick-release skewer housing and is completely restrained from rotation via a tri-tumbler locking apparatus. The cam member is arranged in a combination lock type design and, therefore, cannot be rotated. In dialing in a proper lock combination, a series of locking pins which would otherwise prevent rotation of the cam about the bike's axle are aligned such that the cam member is allowed to freely spin. A pivoting lever is also provided not only for aiding in compressing the cam member against the axle, but also for removing compression of the cam member against the axle which aids in the removal of the quick-release hub once a proper lock combination has been dialed.Type: GrantFiled: May 16, 2001Date of Patent: December 31, 2002Inventor: Scott Andrew Krahl

Patent number: 6267528Abstract: A coupling structure of a variable length shaft, comprises a pipe member having an end formed with a plurality of slits elongated in the axial direction to be capable of expanding and diminishing in diameter, an intermediate shaft spline-fitted in the end of the pipe member, and a ring member fitted on an outer periphery of the end of the pipe member, the intermediate shaft being fastened by the end of the pipe member. A holder is releasably attached to an end of the ring member to expand a diameter thereof and thereby reduce a slide frictional resistance of the pipe member against the intermediate shaft. When the holder is released, the ring member diminishes in diameter, and a fastening force of the pipe member on the intermediate shaft is increased.Type: GrantFiled: July 1, 1999Date of Patent: July 31, 2001Assignee: NSK Ltd.Inventor: Kiyoharu Higashino

Patent number: 6179513Abstract: A clamp for securing a canopy to a telescoping rafter while simultaneously securing the rafter is provided by the present invention. A handle is pivotally mounted on a rafter arm used to support and extend a retractable awning canopy. When the handle is rotated to a first position, the clamp is disengaged and a rafter arm may be extended freely. When the handle is rotated to a second position a spring lock is engaged by a cam attached to the handle, such that the spring lock secures the position of a first member relative to a second member of the telescoping rafter. At least one end of the handle includes a pair of clamping jaws for securing a canopy to the handle. The clamping jaws are tightened or loosened by a thumb screw connecting the jaws. The thumb screw may also be used to secure the handle to the rafter when the handle is not in use.Type: GrantFiled: November 30, 1998Date of Patent: January 30, 2001Assignee: Carefree/Scott Fetzer CompanyInventor: Albert P.

Patent number: 6176641Abstract: An attachment element for mounting or otherwise securing an ancillary device to the vicinity of a machine tool or the like provides quick locking/release on a dovetail element. The attachment member has a base member and a pair of spaced arms forming an open-mouthed way that slides over such a dovetail member. At a locking angle relative to the dovetail, the edges of the arms bear against the dovetail sides, and the edges of the distal ends of the arms bear against the surface from which the dovetail extends. That locking angle is less than 90° angle between the plane of the attachment element and the surface from which the dovetail extends. The attachment element is translatable from its locked orientation to a release orientation by a brief application of manual pressure on it.Type: GrantFiled: December 28, 1998Date of Patent: January 23, 2001Inventor: Noel J.
