Abstract: An orthopedic brace, specifically for a knee, has an antifriction mechanical joint to provide easier movement and has the ability of being custom made for different geometries of rotational movements and ranges. The antifriction mechanical joint has a first bearing plate and a second bearing plate which mate with bearing surfaces of a link. The bearing plates each have a cavity therein and a cam rests in each cavity and is attached to each of the bearing surfaces of the link. Rollers fit between the cams and the cavity so when the joint is flexed, there is only rolling movement between the rollers and the contact surfaces of the cams and rollers.

Abstract: The invention is directed to a connection system for two structural component parts (1, 10) which are constructed as pipe or rod and/or nodal elements and contain connection ends (7, 15) having front recesses. An angle element (22) with a spherical surface (23) at which the two ends of a through-passage (32) penetrating the angle element (22) open out serves to adjust a multitude of angles (.alpha.) between the structural component parts (1, 10), which angles (.alpha.) can be changed preferably between preselected limits. The connection ends (7, 15) are provided in the area of the joint faces (24, 25) with contact surfaces (27, 28) adapted to the spherical surface (23) so that fine, hardly visible joint faces (24, 25) are formed between the structural component parts (1, 10) and the angle element (22).

Abstract: A guide rail has an axially extending recessed groove opening upwardly to guide a nut block to move rectilinearly along the recessed groove when a ball screw shaft is rotated. A pair of strip-shaped magnets are secured to upper surfaces of both side walls of the guide rail. A flexible seal plate made of steel sheet is fixed to the guide rail with its opposite ends fastened to opposite ends of the guide rail. The seal plate slidably engages a guide recess formed in the upper surface of the nut block and crosses axially over the nut block forming an expanded portion along the outer surface of the nut block. A seal pressing member is attached to the nut block to press the expanded portion of the seal plate downwardly, and also to guide the seal plate towards the belt-shaped magnets at front and rear portions of the expanded portion so that the seal plate is attracted by the magnets at portions located before and behind the expanded portion, i.e., the nut block, to cover the recessed groove of the guide rail.

Abstract: This mechanical joint allows relative rotation of two articles (one may be a stationary fixture), on an arbitrary axis. The joint has as much angular-rotation range as a hinge, but as many degrees of freedom as a ball-and-socket or universal joint. It allows transmission, between the objects, of force or flux (e.g., of electricity, gas, or liquid), or both. In can be used as an applied-force or motion sensor, varying electrical contacts or conductivity in response to relative motion or force applied between the articles. In one form the invention is simply a mechanical joint formed of two closely interlocked toroids. The minor cross-section of each toroid is sized to just fit through the central aperture of the other; there is a connection point on each toroid for attachment of one article. By adjusting closeness of fit, a designer can impart to the device a wide range of desirable frictional properties.
