<p>A golf cart propelling system includes a rail formed by a plurality of channel members, each having a U-shaped cross section defined by spaced side walls joined at lower ends thereof by a bottom wall. The side walls have at upper ends thereof flanges extending inwardly toward each other and defining therebetween a longitudinal groove. The channel members are buried in the ground to define a rail extending through selected locations of a golf course with portions of the flanges flush with the ground surface and with the longitudinal grooves of the channel members defining a continuous rail groove. A golf cart has front and rear wheel members running on the flange portions of the rail. Each wheel member has a width no greater than the width of the exposed flange portions. The golf cart is prevented from falling sideways from the rail by at least one vertical shaft attached to the golf cart and extending downwardly therefrom through the groove into the interior of the rail. At least one vertical roller is mounted on the vertical shaft for rotation in a vertical plane in contact with an inner surface of the flanges of the channel members. At least one horizontal roller is mounted on the vertical shaft for rotation in a horizontal plane in contact with inner surfaces of the side walls of the channel members.</p> |
