Abstract
Abstract A telescoping plant stake employing a number of telescoping tubular elements, each of which are fitted with a highly resilient friction element at their inner end. The friction element is secured in a groove with its outermost surface extending slightly above the surface of the tubular member with which it is associated and includes a plurality of diamond like protuberances spaced around the periphery which assume compressive engagement with the encircling tube for that member.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
127 words
A telescoping plant stake comprising at least two telescoping members, the outer of which is tubular; a plug having a flange on one end and having its other end inserted in the lower end of the inner most of said telescoping members, said flange and said lower end defining an annular groove, a generally annular elastomeric friction member secured in said groove and having an outer periphery which is convex in cross-section said outer periphery having a plurality of outward extending local protuberances; said protuberances having a height sufficient that when the outer and inner members are assembled, said protuberances are in compressed contact with the inner wall of said outer tube, said protuberances including tapers extending in each direction of telescoping movement of said telescoping members.
