Abstract
An improved bumper for a fussball game table constructed with a plurality of apertures for improving the energy dissipation thereof. Each bumper is constructed of solid rubber in a generally cylindrical configuration having a central aperture formed therethrough for snugly receiving an actuation rod therein. The walls of the bumper include a plurality of apertures formed axially therethrough for removing mass therefrom. The apertures reduce the structural strength of the rubber bumper and increase its longitudinal compressibility to permit a harder, more reliable rubber to be utilized with sufficient energy absorptive characteristics for dissipating forces generated in the use of the actuation rods of the fussball game table.
Claims13
An improved bumper for a table soccer game structure of the type having a plurality of game figures mounted to rotationally and axially movable actuating rods mounted through side walls disposed about a playing field portion, certain ones of said playing figures disposed upon the actuating rod and having a resilient bumper disposed outwardly thereof, said bumper being positioned to absorb energy resulting from the axial movement of said rod and the impact of said playing figure and bumper against the side wall of the game structure, said improvement comprising said bumper having a cylindrical body having opposite first and second ends;
- a circularly cross-sectioned central passage extending axially through said body between said first and second ends and being radially sized to snugly receive a longitudinal portion of the actuating rod;
- and a circumferentially spaced series of apertures extending radially through said body radially outwardly of said central passage, said apertures extending inwardly through said first end of said body and terminating inwardly adjacent said second end thereof.
An improved bumper mountable on an actuating rod of a table soccer game between an upstanding side wall portion of the game and an outermost playing figure on the rod, said improved bumper being operative to absorb impact forces, axially directed relative to the rod, when said outermost playing figure is forcibly moved by the rod into adjacency with said side wall portion, said improved bumper comprising:
- a cylindrical body formed from a rubber material and having opposite first and second ends;
- a circularly cross-sectioned central passage extending axially through said cylindrical body and opening outwardly through said first and second ends thereof, said central passage being radially sized to snugly receive a longitudinal portion of the actuating rod;
- and
- aperture means formed in said cylindrical body and operative to structurally weaken it in a manner increasing its axial flexibility and shock absorbing capability in response to axial impact forces imposed thereon, said aperture means extending axially through said cylindrical body radially outwardly of said central passage and including a circumferentially spaced series of apertures extending axially through said cylindrical body radially outwardly of said central passage, said apertures extending inwardly through said first end of said cylindrical body and terminating inwardly adjacent said second end thereof,
- whereby said improved bumper is provided with the mechanical durability and chemical degradation resistance attributes of rubber, while at the same time having the enhanced shock absorbing capability of a softer but less durable resilient material.
An improved bumper mountable on an actuating rod of a table soccer game between an upstanding side wall portion of the game and an outermost playing figure on the rod, said improved bumper being operative to absorb impact forces, axially directed relative to the rod, when said outermost playing figure is forcibly moved by the rod into adjacency with said side wall portion, said improved bumper comprising:
- a body formed from a resilient material, said body extending along an axis and having opposite first and second ends spaced apart along said axis;
- a circularly cross-sectioned central passage coaxially extending through said body and opening outwardly through said first and second ends thereof, said central passage being radially sized to snugly and coaxially receive a longitudinal portion of said actuating rod;
- and
- a circumferentially spaced series of apertures extending axially through said body radially outwardly of said central passage, said apertures extending inwardly through said first end of said body and terminating inwardly adjacent said second end thereof.
