Abstract
In a positioning device, first and second members are mounted for movement (e.g. rotation) relative to each other. At least one of the members (e.g. of plastic material) has at least one through slot defining an elastically deformable strip integral with its body portion. In a first embodiment deformable strips flank the sides of a polygonal opening or pivot on one of the members in engagement with a circular pivot or opening in the other member.
Claims3
A wear compensated positioning device comprising:
- a pivot having an outer contour;
- a member;
- a bearing surface portion integrally formed with said member;
- a polygonal shaped opening in said member having a closed inner periphery with substantially straight sides providing said bearing surface portion;
- elongated slots each substantially parallel to, and having a length substantially equal to, each of said sides, with each slot spaced from its respective side a distance effective to form a deformable strip between said side and said slot, said deformable strips being connected at their ends to adjacent ones thereof above apices only of said polygonal shaped opening;
- and
- said deformable strips being resiliently deflected when said opening is fitted over said outer contour of said pivot whereby a wear compensated bearing fit is formed therebetween.
