Patent number: 10330140Abstract: A device for securing a clamping element against unintentional release includes a disk-shaped structure penetrated in an axial manner by a bore hole. A driving profile is defined by the bore hole. The disk-shaped structure is positionable on a component such that the bore hole engages a profile on the component to establish a torque-proof coupling of the disk-shaped structure and the component. The disk-shaped structure has a pair of contact surfaces. Each contact surface of the pair of contact surfaces runs radially and is positioned at a respective axial side of the disk-shaped structure. A profile plane of the driving profile is tilted at an angle with respect to a radial plane of each contact surface of the pair of contact surfaces. A related mounting arrangement is also provided.Type: GrantFiled: April 17, 2015Date of Patent: June 25, 2019Assignee: ZF FRIEDRICHSHAFEN AGInventors: Matthias List, Ingo Decker, Siegfried Selbherr

Publication number: 20120177460Abstract: The invention provides a lock nut with a nut body which has a threaded section with an internal thread and an adjoining inner annular groove. An annular lock washer made of metal is held in the annular groove. An internal thread corresponding to the nut thread is cut into the inner circumference of the annular washer, and the internal thread of the annular washer is offset axially in relation to the nut thread by a distance which is smaller than a thread pitch of the nut thread. According to the invention, the thickness of the annular washer at the inside diameter thereof is greater than the thickness of the annular washer at the outside diameter to thereof. As a result, the elasticity of the annular lock washer and the holding force of the lock nut can be adjusted.Type: ApplicationFiled: July 3, 2009Publication date: July 12, 2012Inventor: Hartmut Flaig

Patent number: 6146074Abstract: A washer for accommodating the shank of a threaded bolt is formed with at least one slanted opposing face having an angle such that the lower face of a nut, threaded on the bolt, is urged into entire surface contact with the upper face of the washer, while the lower face of the washer is urged into entire surface contact with the upper surface of the article fastened to the bolt. Embodiments include an inclination angle of about 2 degrees to about 2.4 degrees, thereby providing an adequate shearing stress to the shank while concurrently providing a substantially vertical force to the upper face of the article to prevent loosening of the knot.Type: GrantFiled: February 17, 1998Date of Patent: November 14, 2000Assignee: Daiyasu Metal Industry Co., Ltd.Inventor: Yoshiji Tutikawa

Patent number: 6099223Abstract: The subject invention relates to an adjustable wedge washer to be used in connection with various material testing machines which are used to mechanically test the strength of bolts, screws and other types of fasteners. The subject adjustable wedge washer includes two wedge washers being joined together mechanically with a snap ring so that they are not separable. The wedge washers then rotate relative to each other to form a variable testing angle relative to the fastener.Type: GrantFiled: December 21, 1998Date of Patent: August 8, 2000Assignee: Instron CorporationInventors: Erik J. Galis, Robert S. Whitelaw, III, Scott L. Maxwell

Patent number: 5309780Abstract: A headlamp adjusting mechanism having a housing member with a passage formed therethrough and an independent nut body is retained in the housing member. The independent nut body has a threaded aperture which is substantially coincident with the passage in the housing. An elongated threaded shaft extends through the passage in the housing and cooperatively engages the threaded aperture in the independent nut body. An assembly for driving the elongated shaft such as a mitered gear arrangement is operatively associated with the housing. The driving assembly transfers motion applied to the assembly to rotate the elongated shaft cooperatively engaged with the threaded aperture in the independent nut body to produce axial displacement of the elongated shaft through the passage.Type: GrantFiled: October 15, 1992Date of Patent: May 10, 1994Assignee: Textron Inc.Inventor: Karl R. Schmitt

Patent number: 4900179Abstract: The mounting cross-piece or node assembly serves for the leak-tight connection of the cut ends of profile sections with one another. These profile sections are provided with an upper lengthwise extending opening and thus form a support or carrier construction or framework in the form of a grid or grid structure suspended at the ceiling of a room, especially a clean room. Filter frames and clean room filters can be mounted in gas-tight fashion in the grid structure. The mounting cross-piece assembly comprises at the cut surfaces of the profile sections to be interconnected and at the sides of the mounting cross-piece confronting such cut surfaces connection elements which can be secured in both of these components.Type: GrantFiled: January 25, 1988Date of Patent: February 13, 1990Assignee: Luwa AGInventor: Walter Kundert

Patent number: 4840529Abstract: A safety lock for adjustment locking structures in which a set screw is passed longitudinally through a jam screw element at a position off-center from the axis and parallel to the axis of the jam screw and locking the jam screw against the end of the coaxially adjacent element in the adjustment stack.Type: GrantFiled: August 17, 1987Date of Patent: June 20, 1989Inventor: Donald A. Phillips
