Patent number: 4592245Abstract: A window regulator comprises a stiff but bendable elongated guide of general C-shape having inturned retainer flanges, and a flexible tape of a cross-section conforming to the interior of said guide, and slidably retained therein by the flanges. The bottom wall of the guide preferably has a channel therein contributing to its stiffness and providing spaces for fasteners for installing the guide or mounting structure thereon. The portion of the tape exposed between the edges of the flanges is formed with rack teeth for driven engagement with a drive pinion preferably mounted on the guide. A housing for the drive pinion has a connector for connecting to one end of the tape, and the end portion of the tape beyond the guide is thus formed into an expandable loop. In order to avoid subjecting the guide to large stresses due to tape tension, a relatively large gear carried by the guide engages the tape at a major bend of the guide. A spring is connected to the gear to act in window-raising direction.Type: GrantFiled: July 28, 1983Date of Patent: June 3, 1986Assignee: Ferro Manufacturing CorporationInventor: Joseph Pickles

Patent number: 4589301Abstract: A linearly infinitely variable mechanism comprises first and second portions which are relatively axially positionable to establish the effective length of the mechanism. A rotary element is axially captured on the second portion. The operative connection between the first portion and the second portion is via a threaded connection of the first portion with the rotary element. The axial capture of the rotary element comprises a twist lock which, when locked, forcefully abuts the ends of the rotary element to preclude its rotation and prevent a change in the effective length of the mechanism provided that the first and second portions are constrained against relative rotation. When unlocked, the rotary element can rotate within its axial capture so that axial forces applied to the mechanism are effective to change its length.Type: GrantFiled: April 27, 1983Date of Patent: May 20, 1986Assignee: Hoover Universal, Inc.Inventor: Glenn C.
