The disclosure relates to roller assemblies and more particularly pertains to a new roller assembly for a storage unit enabling rolling of the storage unit on a surface.
The prior art relates to roller assemblies. Prior art roller assemblies for storage units generally comprise casters that are threadedly couplable to either a bottom or to lower ends of posts of the storage unit.
An embodiment of the disclosure meets the needs presented above by generally comprising a set of bearings and a set of couplers. The bearings are ball transfer type. Each coupler is coupled to a respective bearing and is configured to couple to a bottom of a storage unit so that the coupler is configured to couple the respective bearing to the bottom of the storage unit. The set of bearings is configured to facilitate rolling of the storage unit and contents thereof along a surface.
There has thus been outlined, rather broadly, the more important features of the disclosure in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the disclosure that will be described hereinafter and which will form the subject matter of the claims appended hereto.
The objects of the disclosure, along with the various features of novelty which characterize the disclosure, are pointed out with particularity in the claims annexed to and forming a part of this disclosure.
The disclosure will be better understood and objects other than those set forth above will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed drawings wherein:
With reference now to the drawings, and in particular to
As best illustrated in
Each coupler 14 is coupled to a respective bearing 12 and is configured to couple to a bottom of a storage unit so that the coupler 14 is configured to couple the respective bearing 12 to the bottom of the storage unit. The present invention also anticipates the set of bearings 12 being integral to the storage unit. The set of bearings 12 is configured to facilitate rolling of the storage unit and contents thereof along a surface. The present invention is anticipated to be particularly useful for a storage unit, such as a shelving unit 16, that is positioned in a garage or other enclosure with a hard, substantially flat, floor.
The set of couplers 14 may comprise four couplers 14 that are configured to couple four bearings 12 to the storage unit singly proximate to each bottom corner of the storage unit. The set of couplers 14 may comprise other numbers of couplers 14 depending on the shape and size of the storage unit, such as three couplers 14, and five or more couplers 14. For example, a larger storage unit might have four couplers 14 and associated bearings 12 positioned singly proximate to the bottom corners of the storage unit and two couplers 14 and associated bearings 12 positioned singly on the bottom proximate to a front and a back of the storage unit and evenly positioned between opposing sides of the storage unit.
In the embodiment shown in
Each of a set of holes 24 is positioned in a respective side 26 of the sleeve 18 proximate to the lower end 22. The set of holes 24 may comprise two holes 24 that are positioned in a first pair of adjacent sides 28 of the sleeve 18, as shown in
A set of fasteners 34 is coupled to the sleeve 18 proximate to an upper end 36 of the sleeve 18. Each fastener 34 is configured to couple to a respective post 38 of the shelving unit 16. The set of fasteners 34 is configured to couple the sleeve 18 to the respective post 38 so that the ball 20 extends from the respective post 38 positioning the ball 20 to roll on the surface and thus allowing locomotion of the shelving unit 16.
The set of fasteners 34 may comprise two fasteners 34, with each fastener 34 being coupled to a respective one of a second pair of adjacent sides 40 of the sleeve 18, as shown in
The fastener 34 comprises an orifice 44 and a bolt 46 that is complementary to the orifice 44. The orifice 44, which is threaded, is positioned in the respective one of the second pair of adjacent sides 40 of the sleeve 18. The bolt 46 is configured to be inserted through a respective keyhole slot 48 that is positioned in the respective sidewall 42 of the post 38, positioning the bolt 46 to be threadedly inserted into the orifice 44 to couple the sleeve 18 to the post 38.
The present invention also anticipates the bearing 12 being of other types, such as, but not limited to, lockable drop-in type, flange type, lockable flange type, stud mounted type, lockable stud mounted type, and the like. In the case of the bearing 12 being flange type or lockable flange type, the coupler 14 would comprise a four-holed plate (not shown) that is either coupled to or couplable to the storage unit. In the case of the bearing 12 being stud type or lockable stud type, the coupler 14 would comprise a single-holed plate (not shown) that is either coupled to or couplable to the storage unit.
In use, the sleeve 18 is positioned adjacent to a post 38 of the shelving unit 16 so that each orifice 44 is aligned with a respective keyhole slot 48. Each bolt 46 is inserted through a respective keyhole slot 48 and threadedly inserted into an associated orifice 44 to couple the sleeve 18 to the post 38. The ball 20 of the bearing 12 that is coupled to the sleeve 18 extends from the post 38. With four sleeves 18 coupled singly to the posts 38 of the shelving unit 16, the shelving unit 16 can be positioned upright with the ball 20 of each bearing 12 contacting the surface. The shelving unit 16 and contents thereof thus can be rolled upon the surface.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.
Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the elements is present, unless the context clearly requires that there be only one of the elements.
