The present invention relates, in general, to tools and, more particularly, this invention relates to tools for assisting a user in lifting heavy and awkwardly shaped objects.
Prior to the conception and development of the present invention, lifting tools, as are generally well known in the prior art, have been used to aid people in lifting objects. However, some objects, such as tires and the like, have awkward shapes making them difficult to lift even using a lifting tool. Moreover, tires, in particular, are often lifted to be mounted on vehicles necessitating not only lifting of the tire but also positioning of the tire to align it with the surface upon which it will be mounted. Therefore there is a need for a device which will enable a user to lift and position heavy and awkwardly shaped objects such as tires easily.
Specifically of interest to the present invention are the following: Garnett, U.S. Pat. No. 6,095,745, discloses a caddy apparatus for lifting and carrying a vehicle tire. The device includes a cart frame and a wheel maneuvering structure having a tilt frame and lift carriage slideably mounted on the tilt frame; a pivot mounting of the tilt frame on the cart frame; a tire lift carriage slideably mounted to the tilt frame of the wheel maneuvering structure for engaging and retaining a vehicle tire; and a tire lift carriage lifting and lowering mechanism, preferably employing a hydraulic pump and cylinder.
Kassebaum, U.S. Pat. No. 5,362,194, discloses a lifting and tilting device for facilitating removal, repair and re-installation of large commercial and recreational vehicle wheels comprising a frame supported by wheels, a fork supporting tines, and a hydraulic jack interposed between the frame and the fork. The fork, in addition, includes a kicker. As one actuates the jack, the fork is vertically raised from a wheel receiving position to a predetermined height. Once the fork reaches this predetermined height, the kicker, upon further actuation of the jack, operates to tilt the fork and tines upwardly and outwardly to move the wheel carried thereon into an inclined work position.
Niewald, et al, U.S. Pat. No. 4,571,142 discloses a mechanism for lifting vehicle tires which includes a base framework which is movable along the ground. An elongated mast extends upwardly from the base framework and has a masthead which is movable along the mast. An arm extends outwardly from the masthead and has at its outer end two tandem wheels which are aligned in the same plane and have rotational axes parallel to one another in a horizontal plane. A jack on the base framework is operably connected to the masthead and allows selective lifting and lowering of the masthead. The tandem wheels engage the top inside of the rim of the vehicle tire and cause the vehicle tire to be lifted when the masthead is lifted. When lifted, the tire may be rotated because it is supported only by the rotatable tandem wheels. The tire may also be transported when in a lifted position.
Hawkins, U.S. Pat. No. 4,050,597, discloses a wheel dolly wherein threaded adjustment means are provided for adjusting the level of an inner substantially L-shaped wheel carrying frame within an outer substantially L-shaped wheeled support frame so that the level of the inner frame may be independently adjusted when elevated as into truck tire engaging position so that the proper level may be achieved for removing and replacing truck tires and the like.
Cofer, U.S. Pat. No. 3,951,287, discloses a dolly to receive and hold tires or wheel assemblies for removing or replacing same on a vehicle such as a tractor having a frame with an open front. A lift assembly is mounted on the frame. Stanchion members are secured to the lift assembly and extend upward. A cross member is mounted on the stanchion members. This cross member is movable relative the frame. Lift arms are mounted on the cross member and extend toward the front.
Barosko, U.S. Pat. No. 3,145,859, discloses a dolly type apparatus for transporting heavy objects such as wheel and tire assemblies. The dolly is meant to adjust the position of the wheel and tire assemblies in all directions.
The present invention provides an apparatus for lifting, lowering, supporting, positioning, and transporting a tire. Such apparatus includes a first generally horizontal frame member having a first end and a second end and being manufactured from a first predetermined material and having a first predetermined size and a first predetermined shape. A first generally vertical frame member having a first end and a second end is manufactured from a second predetermined material and has a second predetermined size and a second predetermined shape. The first end of such first generally vertical frame member is operably connected to the first generally horizontal frame member at at least one predetermined location thereon. A pair of arm members each having a first end and a second end are manufactured from a third predetermined material and have a third predetermined size and a third predetermined shape. Such arm members are adjustably connectable at each of such respective first ends thereof to the first generally horizontal frame member at predetermined locations thereon.
It is, therefore, one of the primary objects of the present invention to provide a device for use in lifting various sized tires.
Another object of the present invention is to provide a device which will enable a user to lift and position oversize tires for placement on a vehicle and which can be used to lower such tires from a vehicle to a floor.
Still another object of the present invention is to provide a device which can be used to lift heavy and cumbersome objects thereby minimizing back strain to the person completing such tasks.
Yet another object of the present invention is to provide a device for more easily maneuvering heavy tires into position for installation thereby saving time for a user of such device.
An additional object of the present invention is to provide a device which assists a user in accurately positioning a tire onto a wheel hub.
In addition to the various objects and advantages of the present invention described with some degree of specificity above it should be obvious that additional objects and advantages of the present invention will become more readily apparent to those persons who are skilled in the relevant art from the following more detailed description of the invention, particularly, when such description is taken in conjunction with the attached drawing figures and with the appended claims.
