In general, devices of the type which have been patented tend to be somewhat complicated in terms of structure and hence expensive to produce, or not user friendly, i.e.
difficult to use.
The object of the present invention is to provide a solution to the problems described above in the form of a relatively simple, easily operated and manipulated tire handling device.
Accordingly, the present invention relates to a tire handling device comprising U-shaped, horizontal frame means including parallel side bar means and rear crossbar means interconnecting rear ends of said side bar means; first post means on said rear crossbar means; wheel means supporting a front end of said horizontal frame means; caster means supporting said rear crossbar means, whereby the apparatus can be rolled along a surface and steered; support frame means including parallel, horizontal tire support arms between and parallel to said side bar means; end bar means interconnecting said support arms; second post means on said end bar means;
parallel, vertically aligned, pivot arm means pivotally connected to said first post means and to said second post means for rotating the support frame means between a lower, horizontal, rest position for receiving a tire and an elevated, horizontal position for movement or installation of the tire on a vehicle; and drive means for rotating said pivot arm means and consequently said support frame means to raise or lower said support frame means.
The invention is described hereinafter in greater detail with reference to the accompanying drawings of preferred embodiments of the invention, wherein:

In the following detailed description, wherever possible the same reference numerals have been used to identify the same or similar elements of the different embodiment of the apparatus.
With reference to Figs. 1 to 3, a tire handling device in accordance with the present invention includes a generally U-shaped horizontal frame 1 defined by a pair of parallel side bars 2, the bifurcated front ends 3 of which are supported by rollers 4. Inclined arms 6 extend upwardly and rearwardly from the rear ends 7 of the side bars 2 to a rear crossbar 8. The ends of the crossbar 8 are supported by casters 10 which facilitate steering of the device.
- 2t2~9S8 The frame 1 carries a support frame 11, which is used to carry and manipulate a vehicle tire 12 (Fig. 3). For such purpose a rectangular post 13 is provided in the center of the rear crossbar 8 of the horizontal frame 1. The box-like post 13 includes a rectangular, front to rear opening 14for receiving a top arm or lever 15 and a bottom arm 16 parallel to the lever 15. The lever 15 and the arm 16 are pivotally connected to the post 13 by pins 17. The top end 19 of the lever 15 extends upwardly beyond the post 13. A pin 20 extends outwardly from each side of the lever 15 into an L-shaped slot 21 in a handle 22 for releasably connecting the handle to the lever.
The support frame 11 is also generally U-shaped, including a pair of arms 24, which are parallel to each other and to the side bars 2 of the frame 1, and a rear crossbar 25.
Each arm 24 includes an elongated bolt 26 (Fig. 3) carrying a roller 27. The roller 26 is held on the bolt 26 by a knob 28 and nut 29 on the threaded outer end of the bolt. The rollers 27 are circular in cross section with central depressions for supporting the outer surface of a tire 12. The arms 24, which are approximately the same length as the side bars 2 are close to the sides of the frame 1 for supporting a tire 12 at widely spaced apart locations (Fig. 5). The knobs 28 on the outer, free ends of the arms 24 reduce the likelihood that a tire will slide from the arms.
A tubular post 32 extends upwardly from the center of the crossbar 30. The post 32 is mounted on a bolt 33 connected to the crossbar 25 and is held in position by a washer 35 and a nut 36. The front ends of the lever 15 and the arm 16 are pivotally mounted on pins 38 in a bracket defined by parallel plates 39, which extend rearwardly from the post 32.
Referring to Figs. 4 to 6, a second embodiment of the apparatus is virtually identical to the first embodiment, and includes a pair of wings 40 pivotally mounted on the side bars 2 of the frame 1 for stabilizing a tire 12 on the support arms 24. Each wing 40 includes a rectilinear bottom edge 41, tapering ends 42 and a concave top surface 43. By providing the proper curvature of the top surface 43 ~6 1/2" radius is found to be suitable), the wings 40 can accommodate a variety of tire sizes. A bracket in the form of a lug 45 is provided at each end of the bottom edge 41 for receiving the horizontal arm of an inverted L-shaped rod 46 for pivotally connecting the wing to the side bar 2. As best shown in Fig. 6, each rod 46 is inclined upwardly and towards the center of the frames 1 and 11 so that the wing 40 can be rotated from the rest position (shown in phantom outline) to the use position (shown in solid lines). When the wings are in the rest position, i.e.
inclined outwardl~ and downwardly, they facilitate the roller of a tire onto the support frame 11. In the use position, the wings 40 prevent rotation of the tire 12 on the support arms 24.
The first two embodiments of the invention are intended for manual operation. A tire 12 is placed on the support arms 24 in their lower position (Figs. 1 to 3 and 5), for example by rolling the tire over the side bars 2.
2124~68 Pre6sure is applied to the handle 22 to elevate the support frame 11. The elevated position of the frame 11 is shown in phantom outline in Fig. 3. Because of the parallelogram linkage between the vertical frame 13 and the support frame 11, the support arms 24 remain horizontal during any movement thereof between the lower, tire receiving and elevated positions. Because the frames 1 and 11 are of tubular, skeletal construction and the handle 22 is readily removable, the device is lightweight and compact for easy movement into and out of a vehicle trunk. The parallelogram linkage defined by the vertically aligned lever 15 and the arm 16 means that relatively little manual force is required to raise a tire, with or without a rim.
In the embodiment of the invention illustrated in Figs. 7 to 9, a pair of posts 50 are provided on the rear crossbar 8 of the frame 1, and a stand 51 is provided on the crossbar 25 of the support frame 11. The square cross section posts 50 extend upwardly from spaced apart locations on a sleeve 53 mounted on the crossbar 8. The stand 51, which is intended to stabilize a tire on the support frame 11, is defined by a pair of posts 54 spaced apart by the same distance as the posts 50 and a top bar 55 extending across and connected to the top ends of the posts 54. A generally T-shaped hook 57 is mounted on the rear of the top bar 55. One end of a chain (not shown) is connected to the top bar 55 of the stand 51. The chain is wrapped around a tire and hooked onto the hook 57 to secure the tire to the device.
~12~968 _ Two pairs of bottom arms 15 extend between each post 54 on the frame 11 and a longitudinally aligned post 50 on the frame 1. Two pairs of top arms or levers 16 extend between the posts 54 above the arms 15 to a crossbar 58 and rearwardly of the post 50. The levers 16 are pivotally connected to the posts 50 for elevating the tire support frame 11. The crossbar 58 extends transversely beyond the posts 50, and a handle 60 is mounted on one end thereof. The handle 60 includes an elongated body 61, which defines a shallow V when viewed from the side, and a grip portion 62 extending horizontally inwardly towards the longitudinal axis of the device.
The use of two pairs of pivot arms and a pair of posts on each of the frames 1 and 11 results in greater stability and strength in the device. The offset handle 61 facilitates operation and manipulation of the handling device.
With reference to Figs. 10 and 11, the tire handling device can be heavy duty for handling heavy tires, e.g. truck tires. The heavy duty version of the device includes a frame 1 similar to the frame 1 of the first embodiment of the invention, wheels 4 and casters 10. The tire support frame 64 includes a pair of arms defined by bolts 65 connected at one end to an angle iron crossbar 66 by nuts 68, and rollers 69 mounted on the bolts 65 for receiving a tire. A pair of square cross section posts 70 extend upwardly from the crossbar of the frame 1 proximate the ends thereof, and a second pair of posts 72 extend upwardly form the crossbar 66 of the tire support frame 64. Each post 70 on the frame 1 is pivotally connected to a post 72 on the support frame 64 by upper and lower arms 73 and 74, respectively. The upper arms 73 extend rearwardly beyond the post 70 and the outer ends thereof are interconnected by an angle iron crossbar 76. A
stem 77 extends rearwardly and upwardly from the center of the crossbar 76 for receiving a steering handle (not shown).
Bolts 79 and nuts 80 are used to connect the arms 73 and 74 to the posts 70 and 72, except that the front ends of the upper arms 73 are connected to the post 72 by a shaft 82 extending between the posts 72. Washers 83 are provided on the sides of the arms 73, and cotter pins 84 extend through holes (not shown) in the shaft 82 to retain the arms 73 in position on the shafts.
As best shown in Fig. 11, a tee coupler 86 is mounted on the center of the shaft 76 for receiving the top, outer end of a piston rod 87. The rod 87 extends out of a hydraulic cylinder 89, the bottom end of which is pivotally connected to the crossbar 8 of the frame 1 by a clevis 90.
Hydraulic fluid is pumped into the cylinder 89 via a hose 92 from a reservoir 93 using a pump handle 95. When the piston rod is extended, the tire support frame 64 moves from a lower, rest position to an elevated position. The frame 64 is returned to the rest position by releasing the pressure in the cylinder 89.

In the following detailed description, wherever possible the same reference numerals have been used to identify the same or similar elements of the different embodiment of the apparatus.
With reference to Figs. 1 to 3, a tire handling device in accordance with the present invention includes a generally U-shaped horizontal frame 1 defined by a pair of parallel side bars 2, the bifurcated front ends 3 of which are supported by rollers 4. Inclined arms 6 extend upwardly and rearwardly from the rear ends 7 of the side bars 2 to a rear crossbar 8. The ends of the crossbar 8 are supported by casters 10 which facilitate steering of the device.
- 2t2~9S8 The frame 1 carries a support frame 11, which is used to carry and manipulate a vehicle tire 12 (Fig. 3). For such purpose a rectangular post 13 is provided in the center of the rear crossbar 8 of the horizontal frame 1. The box-like post 13 includes a rectangular, front to rear opening 14for receiving a top arm or lever 15 and a bottom arm 16 parallel to the lever 15. The lever 15 and the arm 16 are pivotally connected to the post 13 by pins 17. The top end 19 of the lever 15 extends upwardly beyond the post 13. A pin 20 extends outwardly from each side of the lever 15 into an L-shaped slot 21 in a handle 22 for releasably connecting the handle to the lever.
The support frame 11 is also generally U-shaped, including a pair of arms 24, which are parallel to each other and to the side bars 2 of the frame 1, and a rear crossbar 25.
Each arm 24 includes an elongated bolt 26 (Fig. 3) carrying a roller 27. The roller 26 is held on the bolt 26 by a knob 28 and nut 29 on the threaded outer end of the bolt. The rollers 27 are circular in cross section with central depressions for supporting the outer surface of a tire 12. The arms 24, which are approximately the same length as the side bars 2 are close to the sides of the frame 1 for supporting a tire 12 at widely spaced apart locations (Fig. 5). The knobs 28 on the outer, free ends of the arms 24 reduce the likelihood that a tire will slide from the arms.
A tubular post 32 extends upwardly from the center of the crossbar 30. The post 32 is mounted on a bolt 33 connected to the crossbar 25 and is held in position by a washer 35 and a nut 36. The front ends of the lever 15 and the arm 16 are pivotally mounted on pins 38 in a bracket defined by parallel plates 39, which extend rearwardly from the post 32.
Referring to Figs. 4 to 6, a second embodiment of the apparatus is virtually identical to the first embodiment, and includes a pair of wings 40 pivotally mounted on the side bars 2 of the frame 1 for stabilizing a tire 12 on the support arms 24. Each wing 40 includes a rectilinear bottom edge 41, tapering ends 42 and a concave top surface 43. By providing the proper curvature of the top surface 43 ~6 1/2" radius is found to be suitable), the wings 40 can accommodate a variety of tire sizes. A bracket in the form of a lug 45 is provided at each end of the bottom edge 41 for receiving the horizontal arm of an inverted L-shaped rod 46 for pivotally connecting the wing to the side bar 2.

In the embodiment of the invention illustrated in Figs. 7 to 9, a pair of posts 50 are provided on the rear crossbar 8 of the frame 1, and a stand 51 is provided on the crossbar 25 of the support frame 11. The square cross section posts 50 extend upwardly from spaced apart locations on a sleeve 53 mounted on the crossbar 8. The stand 51, which is intended to stabilize a tire on the support frame 11, is defined by a pair of posts 54 spaced apart by the same distance as the posts 50 and a top bar 55 extending across and connected to the top ends of the posts 54. A generally T-shaped hook 57 is mounted on the rear of the top bar 55. One end of a chain (not shown) is connected to the top bar 55 of the stand 51. The chain is wrapped around a tire and hooked onto the hook 57 to secure the tire to the device.
