Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The following invention pertains to tool transport carts and, more particularly, to such carts that can be used with large workbench tools that can be operated while attached to the transport cart.
2. Description of the Related Art
Trades people and do-it-yourselfers often work in workshops with a wide variety of different tools. Unfortunately, there often isn't sufficient workbench space to keep all of the tools assembled and ready to operate. While the larger workbench tools may be permanently setup on workbenches, smaller workbench tools, hand tools, and the accessories used with these tools are usually stored on shelves or racks.
Today, there are several multi-purpose shop tools available for woodworking and metalworking. Such multi-purpose tools are three-in-one tools that share common components, such as a workbench or electric motor, which can be easily configured to operate as a lathe, mill, saw, and a drill. Their main advantages are that their tools can be conveniently stored in a ready-to-use manner, and occupy less shop space than four separate tools. Their main disadvantage is that the tools are designed to use shared components, which enables the manufacturer to demand a high retail price and control replacement parts and accessories.
What is needed is a relatively inexpensive, universal tool transport cart that enables a plurality of workbench tools to be conveniently stored in a ready-to-use manner.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a tool transport cart for a plurality of workbench tools.
It is another object of the present invention to provide such a cart that is relatively inexpensive to manufacture.
It is another object of the present invention to provide such a cart that includes additional storage space of work pieces, work supplies, small hand tools, safety equipment, and miscellaneous accessories.
These and other objects are met by a universal tool transport cart for large workbench tools, small hand tools, work supplies, safety equipment, and machinery accessories that is mounted on wheels to be easily rolled around a shop area. More particularly, the storage unit includes a lower base unit mounted on four caster wheels. The base unit includes two opposite end storage areas, a relatively large central storage area, and a flat top surface.
Attached to the top surface of the base unit is an elongated, trapezoidal unit designed to hold various large workbench tools, such as a band saw, a jointer, sander, and the like. The trapezoidal unit is shorter in length than the base unit thereby enabling one end of the top surface to be exposed and used as a horizontal workbench. Holes are formed in the exposed top surface of the base unit that enable another workbench tool, such as a scroll saw, to be attached. The trapezoidal unit includes a flat top surface, two diagonally aligned side surfaces, and two end openings. The flat top surface may be used to support a large workbench tool, such as a band saw. The two diagonally aligned side surfaces may be used to attach smaller workbench tools, such as a jointer or belt sander. The end openings enable elongated tools, work pieces and machine accessories to be stored longitudinally under the trapezoidal unit and over the top surface of the base unit. In the preferred embodiment, the diagonally aligned side surfaces are pivotally mounted to the trapezoidal unit thereby enabling the workbench tools mounted thereon to be used in a diagonally or vertically aligned positions.
