ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a mechanic's utility cart and more specifically relates to a mechanic's tool and parts cart. There are many tool chests presently available for use by mechanics. However, they are all used primarily for storing a mechanic's tools and have no room for parts when a mechanic is working on a vehicle and in many instances are of such weight that they cannot be readily moved about. There are no known utility carts presently available that can be used by a mechanic when he is working on a particular job, i.e. there is no place for him to place the parts that are removed from a vehicle to complete the job. In most instances, there are a series of parts that must be removed in a particular order to allow a mechanic to get the point where the repair is needed. For example, if a mechanic is replacing the brake shoes on an auto, the tires must first be removed, requiring a place to keep the wheel cover, which may or may not require a special tool for removing it to gain access to the lug nuts, the axle dust cap, castellated nuts and cotter pins, must all be removed to allow the drums to be removed and once the drums are removed, there are springs that must be removed to gain access to the shoes. All these parts must be kept in a safe place to insure that they are readily available when the mechanic is ready to re-assemble the parts after installing the new brake shoes. The reverse order of steps is taken in re-assembling the parts. The usual approach taken, is for the mechanic to place these various parts on the floor or on a nearby workbench until he is ready to re-assemble them. Quite often, these parts become lost or misplaced due to someone accidentally kicking into them on the floor or someone moving them from their original location because they needed room at the workbench. The subject invention is designed to provide a mechanic with a readily movable cart that can be rolled into the immediate vicinity of where he is working and provide him with space where the removed parts can be stored until he is ready to reassemble them. By means of this invention, lost parts are kept to a minimum, time is saved, because the parts are available when needed and the re-assembling proceeds in an orderly and timely manner.
SUMMARY OF THE INVENTION
A combination tool and parts utility cart is provided with casters for easy movement and a plurality of shelves that are divided into compartments for keeping parts and tools separated. The top level of the cart includes a well that receives a removable tray with lifting handles at opposite ends and four smaller caster at the respective underside corners to allow the mechanic to take the tray with him under a vehicle raised off the floor and deposit parts therein without getting up and going to a bench to place them down. The tray can also be placed on top of the engine when the hood is raised and allow the mechanic to place new and removed plugs therein, without returning to the bench to place the removed plugs down and pick up the new ones, or taken into the interior of the vehicle and set the tray on the seat while doing some under-the-dash repairs, thus saving additional steps and also time. The uppermost portion of the cart, with the tray in place or removed, is of sufficient dimensions to allow the placement of heavier components such as tailgate, door or bumper thereon without collapsing the cart. The middle portion of the cart is made in a U-shape with the center portion partially removed to provide space for the vertical positioning of parts such as a drive axle, bumper, muffler or other lengthy components. In addition to the cut-out portion, the remainder of the second level includes three open compartments, two larger ones of equal size and a third smaller one therebetween for tools or smaller parts. The lowermost or base level of the cart is provided with a plurality of compartments, which are deeper than the compartments of the second level and can accommodate larger parts and tools. The overall unit is made of sufficient structural strength to allow major components of a vehicle to be placed thereon without collapsing the cart. Thus it can be seen that applicant has provided a job specific tool and parts cart that provides the mechanic with a convenient place for storing tools and parts when working on a particular job.
DISCUSSION OF THE PRIOR ART
A prior art search was made of the Patent Office files in the appropriate Classes and subclasses and revealed the following U.S. patents:
U.S. Pat. No. 4,119,044—issued to R. E. Hines on Oct. 10, 1978 and discloses a tool caddy with a lower tray that is supported by casters and an upper tray that has a carrying handle and is removable from its stand. The upper tray has a plurality of hooks for hanging tools.
U.S. Pat. No. 4,7115,573—issued to R. D. Liegel on Dec. 29, 1987 and discloses a tool tray having a lower base or frame that is supported by casters and a vertically extending support for an upper tray. Both the lower base and upper tray have casters thereon.
U.S. Pat. No. 4,795,180—issued to J. Poleyn on Jan. 3, 1989 and discloses a compartmented wheeled tray for use by a mechanic for holding his tools when working beneath a vehicle.
U.S. Pat. No. 5,269,545—issued to Huebschen et al on Dec. 14, 1995 and discloses a molded plastic utility cart with an I-shaped frame and a base with supporting casters. A tray is removably mounted in the upper portion of the unit. This cart serves mainly as tool cart providing ready access to the tools contained thereon.
U.S. Pat. No. 5,460,391—issued to Gantz et al on Oct. 24, 1995 and discloses combination tray and wheeled cart having a lower shelf and an upper tray fixedly mounted to the vertical supports. The unit is convertible from a self-standing unit to a re-configured arrangement whereby the legs can be re-oriented to become handles for carrying the tray. There are a plurality of possible uses for the tray/cart disclosed.
U.S. Pat. No. 5,588,659—issued to Boes et al on Dec. 31, 1996 and discloses a tool cart with a stand with four legs and a pair of rear wheels. The stand supports a plurality of spaced drawers and a vertically extending frame that supports a plurality of horizontally pivotable arms for holding sockets, screw drivers, pliers, wrenches, etc. A horizontal work surface is provided as well as a protective fiberglass cover when not in use.
U.S. Pat. Nos. 5,927,837 and 5,997,116—issued to L. D. Schmidt on Jul. 17, 1999 and Dec. 7, 1999, respectively and disclose a rolling tool box with an upper horizontal surface and a cut-out portion that receives a removable drawer with compartments and includes casters. The sides of the main frame include a pair of diagonal bins that taper outwardly from their bottom connecting point. On the side opoasite to these bins ithere s provided with a removable drawer that includes a handle for carrying.
As can be seen from a review of the above cited prior art, all of the above cited patents disclose trays and carts for storing the tools used by the mechanic or workman, there is currently nothing available that provides a storage area for the parts or components of the vehicle that is being worked on and also the tools requited for that particular job. Applicant has designed a combination tool and parts cart that provides the mechanic with a secure area where he can safely place the parts while the repair is undertaken and have them immediately available when it comes time to re-assemble the component that is being repaired. It can readily be observed that such a tool and parts cart can save the mechanic an enormous amount time in dis-assembling and re-assembling the particular job at hand. It eliminates the many trips the mechanic would have to make back and forth to and from a work bench or other safe place where the parts can be temporarily placed. The cart finds further utility in the situation where the mechanic has dis-assembled a particular job and has ordered the new parts required to finish the job, he can then move on to the nex
