The tire racks 100 may be stacked or unstacked while they are holding a plurality of tires T. In other words, it is not necessary to remove the tires T from the racks 100 for stacking purposes.
FIG. 12 illustrates a side view of three stacked tire racks 100. In one known embodiment, it is desired to stack three tire racks for storing tires in a storage location, such as a warehouse. In this embodiment, the total height of the three stacked tire racks 100 is 302.5 inches (7.7 meters). However, it should be understood that tire racks of different dimensions may be employed, and that a stack of three such racks would have a different height. Further, tire racks may be stacked according to available storage space. Therefore, it should be understood that in storage areas having a lower height, a single tire rack or a stack of two racks may be employed. Similarly, in storage areas having a higher height, four or more tire racks may be stacked. In all cases, the tire racks may be stacked or unstacked without removing the tires.
In one known embodiment, a rack or stacks of racks is mounted to a mounting plate. The mounting plate may be fixed to a floor surface, using known fixing means, such as bolts, screws, nails, pegs, adhesive, and welding. The mounting plate may have posts located in positions corresponding to the posts 120 of the rack 100 and dimensioned to be received in the bottom apertures 190 of the base 110.
In one known embodiment, at least one rack includes casters that extend from one or more posts at a position above the base. The casters may be configured to engage a caster from another rack. Alternatively, the casters may be configured to receive a crossbar that extends from one rack to another.
In one known embodiment, multiple stacks of three racks are disposed in a storage area. At least two of the storage racks are spaced apart by a distance of 84 inches (213 centimeters) to allow a user or a device clearance for removing a tire from a rack or placing a tire in the rack.
FIGS. 13 and 14 illustrate a side view and front view, respectively, of an alternative embodiment of a tire rack 200. The alternative embodiment of the tire rack 200 is substantially the same as the tire rack 100 described above, except for the differences detailed herein. Like reference numerals are used for like components.
In the tire rack 200, an adjustable rail 210 is slidably attached to each of the posts 120 by a plurality of fasteners 220. Exemplary fasteners include bolts and screws. In one particular embodiment, the fasteners 220 are flange bolts having a gripping surface that performs a locking function.
In the illustrated embodiment, fasteners 220 are fixed to the posts 120 and the adjustable rail 210 is moved up or down to a desired height. When the desired height is reached, the fasteners 220 are tightened, thereby fixing the adjustable rail 210 in place. In an alternative embodiment (not shown), the rails 220 have a plurality of detent positions, so the rail may be easily moved to a plurality of desired positions. In another alternative embodiment, the rails 210 have a plurality of apertures (not shown) that can be aligned with the fasteners 220 at a plurality of different heights. In yet another embodiment (not shown), the posts 120 and the rails 220 both have a plurality of corresponding apertures. The corresponding apertures may be aligned at a desired height, and the rail 210 is fixed in place with a fastener that passes through the corresponding apertures.
In the illustrated embodiment, lower side bars 130c are directly attached to the posts 120. However, upper side bars 130a and middle side bars 130b are not directly attached to the posts 120, but are instead attached to the rails 210. The side bars 130a,b may be fixedly or removably attached to the rails 210. Further, the side bars 130a,b may be directly connected to the rails 210, or they may be connected via intervening connectors.
It should be understood that the rails 210 may be placed at a desired height before the side bars 130a,b are attached to the rails 210. Alternatively, the side bars 130a,b may be attached to the rails 210 first. In such an embodiment, the side bars 130a,b and front and back rails 210 may be moved as a unit. Similarly, the crossbars 150 may also be attached to the side bars 130 prior to adjustment, in which case, the side bars 130a,b, crossbars 150, and all rails 210 may be moved as a unit.
In FIGS. 13 and 14, the rails 210 are placed in a first position, holding a plurality of alternative tires T2. The alternative tires T2 have a larger diameter than the tires T illustrated in FIGS. 7, 8, and 10-12. Therefore, the first position is a higher position than the position of the side bars 130 in the embodiment illustrated in FIGS. 1-12, to provide adequate clearance for the tires.
In FIGS. 13 and 14, tires are not held in the upper crossbars 150. The upper crossbars 150 may be left empty to allow an additional tire rack (not shown) to be stacked on top of the tire rack 200. The upper crossbars 150 may also be left empty if the storage space (such as a trailer of a truck) would not accommodate tires placed at this height. However, it should be understood that tires may otherwise be held by the upper crossbars 150.
FIGS. 15 and 16 illustrate a side view and front view, respectively, of the alternative embodiment of the tire rack 200 having the adjustable rail 210 in a second position, holding a plurality of other alternative tires T3.

In alternative embodiments, the crossbeams may be circular, rectangular, or take any geometric shape. In another alternative embodiment, the crossbeams may be welded or otherwise affixed to the crossbeams. In yet another alternative embodiment, the side beams may have apertures that receive the crossbeams.
To the extent that the term “includes” or “including” is used in the specification or the claims, it is intended to be inclusive in a manner similar to the term “comprising” as that term is interpreted when employed as a transitional word in a claim. Furthermore, to the extent that the term “or” is employed (e.g., A or B) it is intended to mean “A or B or both.” When the applicants intend to indicate “only A or B but not both” then the term “only A or B but not both” will be employed. Thus, use of the term “or” herein is the inclusive, and not the exclusive use. See, Bryan A. Garner, A Dictionary of Modern Legal Usage 624 (2d. Ed. 1995). Also, to the extent that the terms “in” or “into” are used in the specification or the claims, it is intended to additionally mean “on” or “onto.” Furthermore, to the extent the term “connect” is used in the specification or claims, it is intended to mean not only “directly connected to,” but also “indirectly connected to” such as connected through another component or components.
While the present application has been illustrated by the description of embodiments thereof, and while the embodiments have been described in considerable detail, it is not the intention of the applicants to restrict or in any way limit the scope of the appended claims to such detail. Additional advantages and modifications will readily appear to those skilled in the art. Therefore, the application, in its broader aspects, is not limited to the specific details, the representative apparatus and method, and illustrative examples shown and described. Accordingly, departures may be made from such details without departing from the spirit or scope of the applicant's general inventive concept.
