Abstract

A pedestal made of inner and outer tubes with a pair of bearings carried by the inner tube and carrying the outer tube. The inner tube has elongated slots extending downwardly from the top end thereof with the top bearing having projections extending through these slots and into the inner tube. A spring shock absorber is connected at its lower end to the lower end of the inner tube and at its upper end to the projections on the top bearing. A pin releasably connects the outer tube to the top bearing for unitary movement.

Claims

1. A shock absorbing pedestal comprising

A) a lower vertically extending tube including a mounting means on the bottom thereof,

B) a top and a bottom bearing mounted on and adjacent the top and bottom ends of said tube, respectively, for low friction movement relative thereto,

C) said lower tube having vertically elongated receiving means in the upper end thereof,

D) projection means on said top bearing extending into said receiving means for relative vertical movement while abutting said receiving means and thereby being held against relative rotative movement,

E) upper and lower securing means,

F) vertically disposed and acting shock absorbing means disposed in said lower tube with the lower end thereof secured by said lower securing means to said lower tube and the upper end thereof secured by said upper securing means directly to said upper bearing,

G) an upper supporting tube for supporting a seat on the top thereof and being disposed in telescopic relationship with said inner tube and supported by said bearings, and

H) tube securing means securing said upper tube to said top bearing for unitary movement.

2. A shock absorbing pedestal according to claim 1 wherein said securing means secures said shock absorbing means directly to said projecting means of said top bearing.

3. A shock absorbing pedestal according to claim 2 wherein said top bearing has a pair of aligned openings therein and said securing means is a pin means disposed in said openings.

4. A shock absorbing pedestal according to claim 3 wherein said tube securing means securing said upper tube to said top bearing connects to said top bearing in one of said openings.

5. A shock absorbing pedestal according to claim 4 wherein said tube securing means is a spring loaded pin.

6. A shock absorbing pedestal according to claim 2 wherein

A) both of said top and bottom bearings are annular and have a peripheral surface and are disposed about and received on the periphery of said lower tube and

B) said upper tube is an outer tube received about the peripheral surface of said bearings.

7. A shock absorbing pedestal comprising

A) a lower vertically extending tube including a mountings means on the bottom thereof,

B) a top and a bottom bearing mounted on and adjacent the top and bottom ends of said tube, respectively, for low friction movement relative thereto,

C) said lower tube having vertically elongated receiving means in the upper end thereof,

D) projecting means on said top bearing extending into said receiving means for relative vertical movement while abutting said receiving means and thereby held against relative rotative movement,

E) upper and lower securing means,

F) vertically disposed and acting shock absorbing means disposed in said lower tube with the lower end thereof secured by said lower securing means to said lower tube and the upper end thereof secured by said upper securing means directly to said upper bearing,

G) an upper supporting tube having an upper supporting surface thereon being disposed in telescopic relationship with said lower tube and supported by said bearings and movable downward unitarily therewith.

8. A shock absorbing pedestal according to claim 7 wherein said upper supporting surface supports a seat thereon.

9. A shock absorbing pedestal according to claim 7 including means securing
