Abstract
Abstract A shock absorber for use in combination with either or both a seat post and front wheel fork of bicycles and the like. The shock absorber includes a pair of elongated tubes adapted to fit together in a telescopic fashion. The wall of each tube has a pair of slots on opposite sides of the tube so that when the tubes are fitted together, the slots are in general alignment. Plugs are fitted in each tube to compress therebetween a resilient wire mesh pad. A tab is fitted in the slots to keep the tubes together and to enable the tab to slide in the slots of the interior tube as the tubes slide relative to each other. The wire mesh pad serves to absorb vibrations and shocks applied to either tube.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
177 words
A shock absorber comprising a first elongated tube having a first pair of slots on opposite sides of the tube near one end thereof, a second elongated tube, one end of which slidably fits in said one end of the first tube, said second tube having a second pair of slots on opposite sides and extending lengthwise of the second tube and generally aligned with the first pair of slots, the second pair of slots being longer than the first pair, a first plug secured in said first tube between the first pair of slots and the other end of the tube, a second plug secured in said second tube at said one end, at least one resilient wire mesh pad disposed in said first tube between said first and second plugs and partly compressed therebetween, and a tab secured in and extending between the first pair of slots through the second pair of slots such that the tab slides in the second pair of slots as the first and second tubes move relative to each other.
Claim 2
Dependent Claim
177 words
A shock absorber comprising a first elongated tube having a first pair of slots on opposite sides of the tube near one end thereof, a second elongated tube, one end of which slidably fits in said one end of the first tube, said second tube having a second pair of slots on opposite sides and extending lengthwise of the second tube and generally aligned with the first pair of slots, the second pair of slots being longer than the first pair, a first plug secured in said first tube between the first pair of slots and the other end of the tube, a second plug secured in said second tube at said one end, at least one resilient wire mesh pad disposed in said first tube between said first and second plugs and partly compressed therebetween, and a tab secured in and extending between the first pair of slots through the second pair of slots such that the tab slides in the second pair of slots as the first and second tubes move relative to each other.
Claim 3
Dependent Claim
46 words
A shock absorber as in claim 1 wherein said first elongated tube is disposed in a tubular steering head of a cycle and is coupled to the handlebars of the cycle, and wherein the second elongated tube is coupled to the front fork of the cycle.
Claim 4
Dependent Claim
30 words
A shock absorber as in claim 1 wherein said first elongated tube is mounted on a cycle frame, and wherein said second elongated tube is attached to a cycle seat.
Claim 5
Dependent Claim
158 words
A shock absorber for use in bicycles and the like comprising an exterior tube having a pair of oppositely disposed slots in the walls thereof, an interior tube, one end of which is fitted into one end of the exterior tube, said interior tube having a pair of oppositely disposed slots in the walls thereof, the slots in said interior tube being generally aligned with the slots in the exterior tube, a first plug fixed in said exterior tube above the slots, a second plug fixed in the interior tube at said one end thereof, at least one resilient wire mesh pad positioned in the exterior tube between the first and second plugs to be partly compressed therebetween, and a tab extending between the slots of the exterior tube and through the slots of the interior tube and slidable longitudinally in the slots of the interior tube as the exterior and interior tubes move relative to each other.
Claim 6
Dependent Claim
158 words
A shock absorber for use in bicycles and the like comprising an exterior tube having a pair of oppositely disposed slots in the walls thereof, an interior tube, one end of which is fitted into one end of the exterior tube, said interior tube having a pair of oppositely disposed slots in the walls thereof, the slots in said interior tube being generally aligned with the slots in the exterior tube, a first plug fixed in said exterior tube above the slots, a second plug fixed in the interior tube at said one end thereof, at least one resilient wire mesh pad positioned in the exterior tube between the first and second plugs to be partly compressed therebetween, and a tab extending between the slots of the exterior tube and through the slots of the interior tube and slidable longitudinally in the slots of the interior tube as the exterior and interior tubes move relative to each other.
Claim 7
Dependent Claim
130 words
A shock absorber comprising an exterior tube having a tab extending inwardly from the inner wall of the tube, an interior tube, one end of which is fitted into one end of the exterior tube, said interior tube having at least one slot in the wall thereof for receiving said tab, a first plug fixed in said exterior tube between the tab and the end of the tube opposite said one end, a second plug fixed in the interior tube at said one end thereof, at least one resilient wire mesh pad positioned in the exterior tube between the first and second plugs, and said tab preventing rotation of either tube relative to the other while being slidable in said slot as said tubes are moved longitudinally of each other.
Claim 8
Dependent Claim
130 words
A shock absorber comprising an exterior tube having a tab extending inwardly from the inner wall of the tube, an interior tube, one end of which is fitted into one end of the exterior tube, said interior tube having at least one slot in the wall thereof for receiving said tab, a first plug fixed in said exterior tube between the tab and the end of the tube opposite said one end, a second plug fixed in the interior tube at said one end thereof, at least one resilient wire mesh pad positioned in the exterior tube between the first and second plugs, and said tab preventing rotation of either tube relative to the other while being slidable in said slot as said tubes are moved longitudinally of each other.
