The gripping elements increase grip between the adjacent sections when the rotating member is tilted about the tilt axis in a first direction, and decrease grip when the rotating member is tilted about the tilt axis in a second and opposite direction to enable rotation of the rotating member.

Abstract: A mechanism for adjusting vehicle handlebars includes a lower hub intergral with a vehicle steering column, and an upper hub formed as an integral part of the handlebars. Two opposed diamond-shaped plates rotationally receive both hubs. Two locking gears, one integral with each hub, form various interlocking engagement with one of the plates, corresponding to different handlebar position settings. A release lever, pivotally attached to one of the plates, is pivotable to urge the plates away from one another to release the locking engagment of the gears and projection groove, enabling movement of the handlebars to different settings. A spring loaded detent prevents inadvertent release of the mechanism, and must be moved against the force of a torsion spring prior to the pivoting of the release lever.

Abstract: A swivel lock assembly includes pivotally interconnected first and second rods. A pivot of resilient material has two radially projecting end extrusions, one of which is passed through the bores of the rods and rotated to engage with a shallow groove of the corresponding rod surface. The other of the extrusions presses the rods against each other with its inwardly extending push arms so that the circularly arranged teeth of the rods mesh with each other, thereby preventing relative rotation of the rods. The rods can be forced by hand to disengage from each other, permitting the relative rotation of the rods. When the operator lets go of the rods, the push arms of the pivot press the rods toward each other to interlock the rods.

Abstract: The tool of the present invention is comprised of a scoop with a short upright stem which is connected to a threaded broom handle of any length thru a multi-positional, self-locking, rotary acting articulated joint.
