Abstract: A telescoping self-aligning tube having an inner tube dimensioned and configured to fit within an outer tube which is equipped with a guide slot for receiving a snap button, thereby preventing rotation of the inner tube relative to the outer tube. The guide slot allows the telescoping tube to self-align such that the user does not have to twist and maneuver the inner and outer tubes when changing the tube length in order to align a detent button with its detent hole. Embodiments include detent holes located both within and radially opposite with respect to the guide slot. A Foam insert may be located on both ends of the inner tube allow the telescoping tube to be buoyant. A special layer of rubberized or polymer coating protects the cleaned surface from abrasions due to contact with the telescoping tube.

Abstract: An adjusting device for a push-pull rod (1) such as is used in motor vehicles between the gearshift lever and the tranmission. To achieve continuous length compensation, the invention uses a spring (4) to directly or indirectly effect clamping between the push-pull rod (1) and the housing of the adjusting device or a connector (6).

Abstract: A telescopic tube joint has a sleeve, which is adapted to securely coupling an outer tube and an inner tube, and defines a locking chamber therein. At least two locking rings are received in the locking chamber of the sleeve, the locking rings are forced apart by a biasing member between the locking rings and cause the locking rings to press on the outer wall of the inner tube to hold the inner tube in place with respect to the outer tube. When a user squeezes the locking rings, the inner tube will slide freely in the outer tube.

Abstract: The tiltable component in a tilt type vehicle steering column can be locked in selected positions of adjustment by an external locking mechanism that includes an elongated rod having pivot connections with the stationary and movable components of the column. A rotatable locking sleeve encircles the rod to form a rigid connection between the rod and one of the pivot connections. Meshed teeth on the rod and sleeve prevent the rod from moving in the longitudinal direction. By rotating the sleeve on the rod it is possible to shift the teeth out of mesh, such that the rod can move longitudinally to set the movable component of the steering column in a new selected position of adjustment.
