Abstract: A mount for attachment to a window having a pair of faces and a hole extending between the faces has a body adapted to engage one of the faces and having a pin projecting with play through the hole and past the other face, a retainer adapted to engage the other face and formed with a passage snugly receiving the pin, and an eccentric ring engaged in the hole and having an eccentric passage snugly receiving the pin. Formations on the ring and on the retainer are interengageable in any of a multiplicity of angularly offset position of the retainer relative to the eccentric ring and retain the ring against rotation in the hole relative to the bodies. The pin is in a different position relative to the window hole in each of the angularly offset positions.

Abstract: A panel fastener has a hook and cam assembly with a C-shaped leaf spring mounted in a recess in the camming surface of the cam. The recess is formed with a central barrier with opposed ledges on which the spring is mounted. Rotation of the cam causes the spring to frictionally engage the hook and in so doing become compressed and to flex below the recess edges without crimping.

Abstract: A fastener comprises a nut surrounding a collar that in turn surrounds a t, the nut and collar holding a bracket element against a mounting surface. The collar fits closely but slidably within the nut. Of the nut or collar, one has a boss that rides upon a cam surface of the other, so that a camming relation exists between the nut and collar. Turning the nut relative to the collar will thus squeeze the collar into an interference fit with the post so that the fastener attains a locking configuration. A groove adjacent the cam surface accepts the projection and retains it such that the fastener maintains its locking condition. A predetermined torque is needed to rotate the projection to the groove, whereby the fastener is a torque controlled fastener.

Abstract: A two-part electric motor shaft assembly. The assembly includes an elongated shank member which has a cavity hollowed out at one end. A cam pin has one end configured to be received in the shank cavity and secured thereto. The other end of the cam pin forms a cam surface which is eccentric with respect to a longitudinal axis defined by the elongated shank member. By utilizing a two-piece design, the shank member may be formed of a softer and less expensive material than the alloy steel used to form the cam pin since the shank member is subjected to less loading and wear. The two-part motor shaft assembly of the present invention eliminates the stress riser that occurs with application of loading to the transition joint of a single piece design.

Abstract: A coupling has a first coupling part comprising a holding rod which is provided with a groove for the engagement of locking balls. The locking balls are radially movably arranged in transverse bores of a holding element arranged on a second coupling part. In a non-operative position of the rollover bar, the locking balls are pressed by a cone surface of a locking member into the groove of the holding rod. If the locking member is displaced in a sensor-controlled manner axially against the effect of a spring by an electromagnet, the holding rod is released. To achieve a construction which is as compact as possible and which permits a housing of the coupling also in the very limited space conditions in a motor vehicle, the holding element with the locking balls and the locking member are arranged inside the electromagnet.

Abstract: A quick-change mechanism is provided between a male member and a female member which has a socket with an axis. A flange is provided on each member, and in the flange of the female member an eccentric circular cam is pivotably mounted on one side of the socket. The cam may be pivoted through an arc between a locked and an unlocked condition in a single plane. The unlocked condition moves the cam laterally outwardly beyond the cam follower surface in the male member. As the cam is rotated towards the locked condition, the cam locking surface moves in a single plane laterally inwardly and establishes an axially inward force on the cam follower surface. The quick-change mechanism is small and compact and contained entirely within the flange of the female member. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.

Abstract: A joint connection for space frameworks made of rods and joint members wherein the joint members have concentric threaded bores for receiving threaded bolts for the connection of the rods with the joint members. The required torque is applied by means of screwing tools through non-rotatable but axially slidable drive sleeves on the threaded bolts. The drive sleeves inserted between the rod ends and joint members are also used to bias the threaded bolts so strongly that the bias force is greater than the charges from the outside which have a dynamic effect, in order to avoid the danger of fatigue fractures. For this purpose, each drive sleeve may be formed of three parts which, on the basis of cooperating helical surfaces with suitable relative rotation of the middle part relative to both outside parts, are axially adjustable in opposite directions to axially bias the threaded bolt to lengthen it and therewith to axially bias it.
