Abstract:
A shock absorbing device for an elongate structure adapted for contact with a bearing surface and suitable as a ski pole, walking stick, crutch, for damping in both compression and extension, said structure including a generally cylindrically shaped member (1) and a generally cylindrically shaped element (2) telescopically disposed with respect to member (1), member (1) and element (2) being coaxial with said elongate structure and being telescopically movable with respect to each other in response to stresses imparted to said structure from contact with said bearing surface, said shock absorbing device comprising:a first end plate (1') on said member (1) and a second end plate (2') on said element (2);a first elastic member (7) having a first base surface anchored to said first end plate (1') and a second base surface anchored to said second end plate (2');a second elastic member (8) disposed within said element (2) and engaging said second end plate (2') in opposition to said first elastic member (7),whereby said first and second elastic members act to dampen in both compression and extension.
