A universal joint between an upper steering shaft and a lower steering shaft in a tilt-adjustable motor vehicle steering column includes a pair of bifurcated yokes formed to near-net-shape integrally with the upper and lower shafts, a plastic jacket molded in-situ on each of the bifurcated yokes, and a plastic centering sphere. Each of the plastic jackets has a pair of exposed, frusto-conical bearing surfaces molded thereon which slidably engage corresponding frusto-conical side walls of cross grooves in the plastic centering sphere.

A connector for handles and shoulder belts of bags, or other traveling containers, includes a base member (1) provided with holes (2) or other mechanism for securing it to the bag. Provided at the ends of the base member, on the exposed face, are equal and parallel protrusions (101) provided with respective transverse holes (5) aligned with each other and having pivoted thereon, by use of a spindle (4) or any other suitable device, a body member (3) which may effect a 180.degree. oscillation about the spindle and which--when disposed upright and abutted against the base member--exposes a recess also directed upwards (7). The flattened end portion of an axially hollow stem (8) is pivotably connected by use of a screw (10) or any other suitable device, orthogonally to the pivotal spindle (4) of the member so that it can effect an oscillation of sufficient amplitude, the end portion of the handle or shoulder-belt (M-T) being secured by means of a screw or any other suitable device within the hollow stem.

A universal joint includes a first shaft member having a cylindrical portion, a pair of yoke portions at a free end thereof and a ball-like portion formed between the yoke portions and a second shaft member having a cylindrical portion and a pair of yoke portions at a free end thereof. The ball-like portion is formed integrally and inseparably with the yoke portions of the first shaft member. The first and second shaft members are thus detachably and movably connected with each other through engagement between the ball-like portion of the former and the yoke portions of the latter.
摘要:
A locking pin for connecting elements having a common bore comprising two coupling units. The coupling action is provided by teeth which engage when the two coupling units are engaged. The teeth exhibit a ratchet effect, whereby the coupling units can be engaged relatively easily by pushing the coupling units together but cannot be easily disengaged by pulling them apart.

A pair of knuckles each including a base element and a pair of transversely spaced longitudinally extending lugs on the base element. The lugs on each knuckle are pivoted in a pair of lugs secured to the frame of one of the leading and trailing equipment units, the two knuckles being positioned on relatively transversely positioned axes. The knuckles are interconnected by a longitudinal pin extending through the base elements, the longitudinal pin being dimensioned to enable longitudinal play between the knuckles, and relative angular movement therebetween.
