ABSTRACT:
BACKGROUND OF THE INVENTION
1. The Field of the Invention
The present invention relates to golf bag carts. More particularly, it relates to a lightweight golf bag cart that can be used with a conventional golf bag and that can be easily disassembled and stored.
2. The Relevant Technology
Although a golf bag is convenient for its short-range portability, it becomes quite cumbersome when used on the golf course, carrying it from green to green. In addition, the size and weight of golf bags has been increasing. As a result, golf bag carts are frequently used on the golf course where the golf bag is placed in or attached to the cart to permit wheeling about the golf course during the game. While present-day carts have eased the burden of carrying the golf bag, they have several disadvantages.
Most golf bag carts are separate pieces of equipment from the golf bag with which they may be used. Therefore, a golfer must transport both the golf bag and the golf bag cart separately or hope that he can rent a golf bag cart at the golf course. The inconvenience of having to carry and store a separate piece of equipment has limited the use of golf bag carts.
In addition, most golf bag carts are bulky and heavy, making them difficult to transport and to store along with equally bulky golf bags. Thus, transporting a golf bag cart from the house to the car and from the car to the golf course can be a difficult task, especially for those who may not have the physical strength necessary for such a task.
Furthermore, the wheels on golf bag carts can become caked with mud, dirt, or grass in the process of being used on a golf course. When a conventional golf bag cart with dirty wheels is transported or stored, dirty wheels can soil areas in a car or home. This is undesirable.
Moreover, many golf bag carts that have solved some of the problems above can only be used with golf bags especially designed for use with the specific cart. Thus, the purchase of a lightweight, transportable golf cart may require the purchase of a new golf bag as well. This can be expensive.
A further difficulty with some present-day disassemblable golf bag carts is that the detachable wheels, handles, etc. either require additional storage space or take up space that otherwise could be used for golf equipment.
Still a further difficulty with present-day disassemblable or collapsible golf bag carts is that the small size of the components necessary for portability has forced the distance between golf carts' wheels to be small, rendering the golf bag cart relatively unstable.
SUMMARY OF THE INVENTION
The invention relates to a golf bag cart comprising a plurality of wheels, a collapsible frame, an adjustable support means for supporting a conventional golf bag, a storage means for storing the wheels, an adjustable securing means for releasably securing the conventional golf bag to the collapsible frame, and a handle.
The golf bag cart has a fully assembled state and a disassembled state. In its fully assembled state, a conventional golf bag is attached to the golf bag cart to permit wheeling about a golf course during the game. In its fully assembled state, the golf bag cart has a proximal side and a distal side. The proximal side of the golf bag cart is that side which would be pulled by a user. The distal side of the golf bag cart is the opposite side. The golf bag cart also has a top and a bottom. The bottom of the golf bag cart is that side which is closest to the ground when the golf bag cart is being pulled along the ground. The top of the golf bag cart is the opposite side. In its disassembled state, the golf bag cart takes up less room than conventional golf bag carts.
The collapsible frame comprises an axle member, a horizontally disposed support means having a proximal end and a distal end, and a vertically disposed support means having a top end and a bottom end.
The collapsible frame has a fully assembled state and a disassembled state. In the collapsible frarne's fully assembled state, the bottom end of the vertically disposed support means is attached to the axle member, and the vertically disposed support means extends substantially vertically from the axle member. The proximal end of the horizontally disposed support means is attached to the axle member, and the horizontally disposed support means extends substantially horizontally from the axle member. In the collapsible frame's disassembled state, the vertically disposed support means and the horizontally disposed means are disconnected from the axle member or are rotated so as to be disposed substantially parallel to the axle member.
In the golf bag cart's fully assembled state, the wheels are each releasably journaled on the axle member.
Furthermore, the distal end of the horizontally disposed support means is connected to the adjustable support means, so as to prevent the adjustable support means from moving vertically relative to the collapsible frame. The adjustable support means supports the bottom of the conventional golf bag and can be adjusted to accommodate conventional golf bags of varying diameters.
The top end of the vertically disposed support means is connected to the adjustable securing means, so as to prevent the adjustable securing means from moving relative to the collapsible frame. The adjustable securing means restrains any movement of the top of the conventional golf bag and can be adjusted to accommodate conventional golf bags of varying diameters.
The storage means is rigidly connected to the adjustable support means.
In the golf bag cart's disassembled state, the wheels are removed from the axle member and are placed within the storage means. The collapsible frame is put in its disassembled state and placed within the conventional golf bag as a conventional golf club. The adjustable support means and the adjustable securing means remain attached to the conventional golf bag.
