Abstract

A shock absorbing platform includes a bottom plate and a top plate joined to one another at their respective rearward and side peripheral edges by elongate rigid links that enable the plates to remain in parallel relation to one another as the top plate moves in relation to the bottom plate. In a first embodiment, an opening formed in the bottom plate accommodates the upper end of a platform-supporting pedestal so that the platform may be retrofit onto a pre-existing pedestal. The forward edge of the platform is open so that height-adjusting and seat-rotating pins are readily accessible. A cylinder is pivotally mounted on each outboard side of the platform and its plunger bears against a roller of a truncate link assembly that interconnects the top and bottom plates at their respective forward edges. Downward forces applied to the top plate are resisted by the cylinders.

Dependent claims

A platform that absorbs shocks, comprising:

a bottom plate having a central opening formed therein, said central opening adapted to receive an uppermost end of an upstanding pedestal;
a flat plate disposed in elevated relation to said bottom plate, said flat plate adapted to be secured to an uppermost end of said upstanding pedestal in surmounting relation thereto;
a top plate disposed in parallel relation to said bottom plate;
a plurality of pairs of rigid link members positioned at the side rearward edges of said top plate and said bottom plate in interconnecting relation thereto;
each pair of rival link members being interconnected to one another in scissors interconnection so that said top plate and bottom plate remain in said parallel relation to one another when said top plate is displaced relative to said bottom plate
a pair of shock-absorbing damper means disposed between said top plate and said bottom plate in interconnecting relation thereto;
and
said platform adapted to be retrofit onto said upstanding pedestal by mounting said flat plate to said upstanding pedestal in surmounting relation thereto.
