Patent ID: 7950632

Claim:
A device for damping the relative motion between a handle ( 24 ) and a rod ( 22 ) of a pole ( 20 ), the device comprising: a tube ( 3 ) with a closed lower end ( 19 ), the lower end ( 19 ) fixed within the rod ( 22 ); a rod-shaped body ( 5 ) with a free lower end held in the tube ( 3 ); an elastically deformable seal ( 13 ) on the free lower end of the rod-shaped body ( 5 ), under a pressure the seal being deformed to bear against an inner surface of the tube ( 3 ); upon a displacement of the rod-shaped body ( 5 ) into the tube ( 3 ), a gas compression spring comprises a gas-filled space located within the tube ( 3 ) between the closed lower end ( 19 ) of the tube ( 3 ) and the seal ( 13 ) bearing against the inner surface of the tube ( 3 ); and a helical compression spring ( 17 ) clamped between i) the closed lower end ( 19 ) of the tube ( 3 ) and ii) the free lower end of the rod-shaped body ( 5 ), wherein under the displacement of the rod-shaped body ( 5 ) into the tube ( 3 ) the helical compression spring ( 17 ) creates the pressure on the seal ( 13 ) that deforms the seal ( 13 ) to bear against the inner surface of the tube ( 3 ).
