A battery powered golf club cart having an elongated handle which controls both the power applied to its rear wheels and a brake associated with its front wheel. When the handle is depressed an electric motor which rotates the rear wheels is actuated and the front brake is released. When the handle is raised, the electric motor is disabled and the front wheel is drawn into contact with a braking member. A full set of golf clubs are vertically held in a flat rack forming a part of the cart framework and, after removal of the battery, the cart may be collapsed into a thin flat package, convenient for transporting and storage, without need for removal of the golf clubs.

1. An electrically powered golf cart comprising: a tricycle including a single forward wheel, and first and second rear wheels, axle means supporting said rear wheels, a drive gear assembly for rotating said axle means; a controllable electric motor for providing rotational power to said drive gear assembly; a rack for supporting a plurality of golf clubs in vertical parallel spaced relation substantially over said foward wheel; means for collapsing the golf cart into a flat, compact unit without removal of the golf clubs from said rack; a pair of triangular frames forming the framework of said cart, each of said pair of frames being pivotally coupled to said axle means and to the top and bottom sides of said rack, said rack forming one leg of the triangular frame for each of said pair of frames; a control handle movable substantially vertically within said framework for controlling the excitation of said motor and the braking of said forward wheel; and a frame for mounting a storage battery, said frame being supported by hooks removably attached to members of said framework and further supported by a linkage pivotally connected to said movable control handle, whereby the raising of said handle moves said frame toward the center of said framework. 2. The golf cart as recited in claim 1 further comprising an electrical switch coupling said battery to said electric motor, said electrical switch being positioned in the path of said battery frame such that it is opened and closed, respectively, by the movement of said battery frame toward the center of said cart framework and away from the center of said cart framework. 3. The golf cart as recited in claim 1 wherein the single forward wheel of said tricycle is rotatable on an axle supported at the first end of a fork, the second end of said fork being pivotally connected to said movable control handle, a point on the top of said fork between said first and second ends lying against the lower surface of a cross member across the bottom of said rack, said cross member contacting the periphery of said forward wheel to operate as a brake upon the raising of said movable handle. 4. The golf cart as recited in claim 3 wherein the frame members of the triangular framework pairs coupled between the rear wheel axles and the top sides of said club rack are hinged on the inner surfaces of the frame members whereby, upon removal of said battery frame and the withdrawing of said forward wheel into the center of said framework behind and parallel with said club rack, the hinged and pivoted legs of said framework pairs may be collapsed. 5. A golf cart comprising: a collapsible frame assembly including a separated pair of triangular framework members coupled together at a lower, rearward apexes thereof by a rear axle, said frame assembly including a braking surface; a pair of rear wheels coupled to said rear axle; an elongated control handle attached to said frame assembly; a front wheel attached to a lower end of said control handle, said front wheel being located proximate lower, forward apexes of said pair of triangular frameworks when in an operating position, and being locatable within said frame assembly when said collapsible frame assembly is in a collapsed position; said front wheel being coupled to said control handle by a pivoting link, whereby said front wheel can be drawn against said braking surface by the vertical movement of said control handle; and carrying means attached to said frame assembly adapted to carry a set of golf clubs. 6. A golf cart as recited in claim 5 further comprising: an electric motor coupled to said rear axle; a battery support attached to said collapsible frame; a storage battery supported by said battery support; and means for selectively coupling said storage battery to said electric motor. 7. A golf cart as recited in claim 6 wherein said means for selectively coupling said storage battery to said electric motor includes switch means responsive to the vertical position of said control handle. 8. A golf cart as recited in claim 7 wherein said battery support is pivotally supported by said collapsible frame assembly and is connected to said control handle by a pivoting link, and wherein said switch means is controlled by the pivotal motion of said battery support. 9. A golf cart as recited in claim 8 wherein said means for selectively coupling said storage battery to said electric motor includes power adjustment means for varying the power supplied to said electric motor. 10. A golf cart comprising: a collapsible frame assembly supported by a plurality of wheels; braking means for braking at least one of said wheels; an electric motor for rotating at least one of said wheels; a storage battery; coupling means for coupling said battery to said electric motor; club carrying means attached to said frame assembly; and a control handle coupled to said frame assembly and operative to control said braking means, said braking means including a linkage coupling a wheel to said control handle such that a movement of said control handle draws said wheel against a surface of said frame assembly. 11. A golf cart as recited in claim 10 wherein said coupling means includes a switch coupling said battery to said electric motor, said switch being responsive to the position of said control handle. 12. A golf cart as recited in claim 11 further comprising a pivoting support for said battery coupled to said frame assembly, and a pivoting link attaching said support to said control handle, and wherein said switch is responsive to the pivotal position of said support. 13. An electrically powered golf cart comprising: a pair of triangular frame members each having a base leg, a rear folding leg, and a front support leg; an axle coupling said pair of frame members together proximate a juncture of said rear folding legs and said base legs; a pair of rear wheels attached to opposing ends of said axle; a sliding control handle assembly including a first member slidingly supported by collar means between said rear folding legs of said pair of triangular frame members, and a second member slidingly engaged with said first member and pivotally supported by a pivotal support means between said base legs of said triangular frame member; and a front wheel operationally disposed approximately one half the way between junctures of said front support legs and said base legs of said triangular frame members, means coupling said front wheel to said control handle, whereby said front wheel can be drawn within said front support legs, said rear folding legs, and said base legs by sliding said first member of said control handle in an upward direction. 14. An electrically powered golf cart as recited in claim 13 wherein said first member and said second member of said control handle are telescopically engaged.
