Wheel assembly for transportable carton
A transportable carton assembly is disclosed that includes a carton defining a bottom rear corner edge portion having a pair of longitudinally spaced apart apertures formed therein, and an elongated shield retained within the bottom rear corner edge portion of the carton and including a pair of longitudinally spaced apart wheels positioned to extend through the longitudinally spaced apart apertures formed in the bottom rear corner edge portion of the carton for transporting the carton over a surface.
1. A wheel assembly for a transportable carton, comprising:
a) an elongated shield having a planar base portion defining upper and lower surfaces, opposed front and rear edges, opposed side edges and a central axis, and a pair of support flanges extending upwardly from the opposed front and rear edges of the base portion at opposed angles to one another relative to the upper surface of the base portion, each support flange having a respective interior and exterior surface; and
b) a pair of longitudinally spaced apart wheel wells formed within the shield, wherein each wheel well is adapted and configured to accommodate a respective wheel mounted on an axle, and wherein struts extend outwardly from the exterior surfaces of each support flange along peripheral edges of the wheel wells formed therein.
2. A wheel assembly as recited in claim 1 , wherein each support flange extends upwardly from a respective edge of the base portion at an angle of about between 40 and 45 degrees relative to the upper surface of the base portion.
3. A wheel assembly as recited in claim 1 , wherein the pair of support flanges includes a front support flange extending upwardly at an angle from the front edge of the base portion and a rear support flange extending upwardly at an angle from the rear edge of the base portion.
4. A wheel assembly as recited in claim 3 , wherein the front support flange is wider than the rear support flange.
5. A wheel assembly as recited in claim 3 , wherein the lower surface of the base portion and the exterior surface of rear support flange includes a plurality of spaced apart outwardly projecting rounded nubs.
6. A wheel assembly as recited in claim 1 , wherein each wheel well has an arcuate wheel housing associated therewith that extends between the respective interior surfaces of the support flanges.
7. A wheel assembly as recited in claim 1 , wherein each wheel well has an elongated axle channel associated therewith, which is formed in the base portion aligned with the central axis thereof.
8. A wheel assembly as recited in claim 7 , wherein each axle channel opens through the lower surface of the base portion, and includes an enclosed hub area projecting upwardly from the upper surface of the base portion.
9. A wheel assembly as recited in claim 1 , wherein opposed side walls extend from side edges of the interior surfaces of each support flange and from the upper surface the base portion along the side edges thereof.
10. A wheel assembly as recited in claim 1 , wherein a wheel mounted on an axle is accommodated within each of the wheel wells.
