Abstract:
An-exercise device having a first part (11) and a second part (12) which turn with respect to each other at a friction assembly, a user interface connected to each of said parts, said friction assembly comprising:an outer cylinder (28â€²) affixed to first part (11), said outer cylinder (28â€²) having an inwardly facing cylindrical friction surface (28); at least one elastomeric ring (35,36) affixed to said second part (12), said elastomeric ring (35,36) having an outwardly facing cylindrical ring surface (35â€²,36â€²) adjacent said inwardly facing cylindrical friction surface (28) and said elastomeric ring (35,36) being in a confined space and having two outwardly facing end surfaces (38,39); and means for adjustably compressing said at least one elastomeric ring (35,36) from an outwardly facing end surface of said elastomeric ring (35,36), thereby compressing said at least one elastomeric ring (35,36) and distorting it thereby urging said outwardly facing cylindrical ring surface (35â€²,36â€²) outwardly against said inwardly facing cylindrical friction surface (28), thereby increasing a resistance movement between said cylindrical ring surface (35â€²,36â€²) and said cylindrical friction surface (28), so as to generate friction for said exercise device.
