Golf cart system with embedded rail having inclined surfaces

A golf cart system comprising:

• a longitudinal rail to be implanted in the terrain of a golf course and formed by a plurality of channel members;
• each said channel member having a transverse cross section defined by spaced side walls joined at lower ends thereof by a bottom wall having an inner upper surface, said side walls having at upper end thereof upper walls extending inwardly toward each other and having inner lower surfaces, said upper walls having spaced inner edges having extending upwardly therefrom mouth portions, and said inner edges and said mouth portions defining therebetween a longitudinal groove opening downwardly into the interior of said rail, said inner upper surface of said rail lower wall being formed by two inwardly and downwardly convergent inclined surfaces, and said inner lower surfaces of said rail upper walls comprising inwardly and upwardly convergent inclined surfaces, and said inclined surfaces of said bottom and upper walls as well a inner surfaces of said side walls defining within said channel member a longitudinal channel having a generally hexagonal transverse cross section;
• a golf cart to be moved along said rail;
• support means mounted on said cart and extending downwardly therefrom through said longitudinal groove, said support means comprising at least one vertical shaft and a frame mounted on said vertical shaft;
• at least two pairs of wheels mounted on said frame within said rail interior at positions forwardly and rearwardly with respect to said vertical shaft, each said pair including two wheels rollingly contacting respective said inner upper surfaces of said rail bottom wall;
• means supported by said cart for rotating at least some of said wheels for thereby moving said cart along said rail;
• and
• means for preventing said cart from falling sideways from said rail and comprising a pair of rollers supported by said frame between said two pairs of wheels and positioned within said rail interior, each of said rollers contacting a said inner lower surface of a respective said rail upper wall.
