Abstract
There is provided a device to rotationally secure a member with respect to a base. The member is connected to an axle having an ellipse-shaped cross section through an elliptical or truncated-oval cavity for receiving the axle. As the member rotates, different tensions are experienced by the spring based on the orientation of the ellipse-shaped cross section with respect to the orientation of the cavity, thereby providing preferred orientations for the rotating member.
Claims8
A device comprising:
- a base comprising a resilient member extending therefrom, the resilient member defining an ellipse-shaped cavity;
- a rotating member;
- an axle extending laterally from a proximal end of the rotating member, the axle comprising an ellipse-shaped cross section, the axle passing through the ellipse-shaped cavity.
A device comprising:
- a base;
- an axle secured to the base, the axle having an ellipse-shaped cross section;
- a rotating member, the rotating member comprising at a proximate end thereof a pair of members defining a truncated-oval shaped opening;
- wherein the axle passes through the truncated-oval shaped opening, thereby rotationally securing the rotating member through the base between a first position where a major axis of the ellipse-shaped cross section is perpendicular to rotating member, and a second position where the major axis of the ellipse-shaped cross section is parallel to the rotating member.

A device comprising:
- a base;
- a first shoulder extending upwardly from the base, the first shoulder comprising an ellipse-shaped cavity;
- a second shoulder extending upwardly from the base, the second shoulder comprising a cavity aligned with the ellipse-shaped cavity of the first shoulder;
- and
- an axle extending through the ellipse-shaped cavity and the cavity, the axle comprising a first section with an ellipse-shaped cross-section, wherein the first section is aligned with the ellipse-shape cavity of the first shoulder.
