Patent number: 6203109Abstract: An ergonomic arm support for supporting the forearm during typing, keying, or assembly operations. The arm support includes an armrest pivotally mounted on a shroud for sliding the armrest to and away from a cantilever disk which is secured to a table or chair. The shroud is pivotally slidable or repositionable relative to the cantilever disk such that the armrest, which is pivotal relative to the shroud may be positioned to provide a wide range of locations for positioning of an individual's forearms. The cantilever disk permits easy or convenient inward, outward, forward, or backward positioning of an armrest relative to an object where the cantilever disk frictionally engages the shroud to lock the armrest into a desired position during use. The shroud may also function as an enclosure of the cantilever disk to prevent inadvertent engagement between an individual and/or the individual's clothes and the cantilever disk.Type: GrantFiled: December 29, 1999Date of Patent: March 20, 2001Assignee: Industrial Ergonomics, Inc.Inventors: Jeffrey D. Bergsten, Donald A. Bergsten

Patent number: 6142570Abstract: An ergonomic arm support for supporting the forearm during typing, keying, or assembly operations. The arm support includes an armrest pivotally mounted on a shroud for sliding the armrest to and away from a stem dowel which is secured to an object such as a table or chair. The shroud is disposed about a pillow block which includes a plurality of roller bearing members which slidably engage one or more of the inside surfaces of the shroud. The slidable pillow block allows the shroud to be slidably and pivotally repositioned relative to the stem dowel. The arm pad is pivotal relative to the shroud and may be positioned to provide a wide range of locations for positioning of an individual's forearms.Type: GrantFiled: December 10, 1999Date of Patent: November 7, 2000Assignee: Industrial Ergonomics, Inc.Inventors: Jeffrey D. Bergsten, Donald A. Bergsten

Patent number: 5884974Abstract: An ergonomic arm support for supporting the forearm during typing, keying, or assembly operations. The arm support includes an armrest pivotally mounted on a slide or a shroud for sliding the armrest to and away from a base which is secured to a table or chair. The slide or shroud is pivotally mounted in the base such that the armrest, which is pivotal relative to the slide or shroud and slidable to and away from the base, is also rotatable about the base to provide for a wide range of fluid motion for the forearm. The armrest further includes a plurality of roller bearing arrangements for facilitation of the slide or shroud and arm support. The roller bearing arrangements engage the slide or shroud proximate to the housing to provide for the fluid movement of the slide or shroud. A shroud may also be provided for enclosure of the roller bearing slide arrangement to prevent inadvertent engagement between an individual and/or the individual's clothes and the slide.Type: GrantFiled: October 29, 1997Date of Patent: March 23, 1999Assignee: Industrial ErgonomicsInventors: Jeffrey D.
