1. Field of the Invention
The present invention relates to wheel devices and more particularly pertains to a new wheel device for an inline skate that includes a removable hub that may be removed and inserted into a new outer wheel when the outer wheel wears out.
2. Description of the Prior Art
The use of wheel devices is known in the prior art. U.S. Pat. No. 6,176,554 describes a wheel assembly for positioning on an inline skate. Another type of wheel device is U.S. Pat. No. 5,564,790 having a design adapted for being positioned on an inline skate. Yet another such wheel assembly is found in U.S. Pat. No. 5,720,529.
While these devices fulfill their respective, particular objectives and requirements, the need remains for a device that allows for easy interchange of outer wheels from a hub attached to an inline skate. Additionally, the device should be stable to ensure that the hub does not rotate with respect to the outer wheel.
The present invention meets the needs presented above by generally comprising a loop that has a centrally disposed opening extending therethrough. The loop defines a wheel and has an outer perimeter surface, an inner perimeter surface, a first lateral side and a second lateral side. A ring is integrally attached to and is coextensive with the inner perimeter surface. The ring is coaxial with the loop and is positioned between and is spaced from the first and second lateral sides. The ring has a first side edge, a second side edge and an inner edge. The inner edge has a plurality of elongated cavities therein extending between and through each of the first and second side edges. A hub assembly is configured to be removably attached to the loop. The hub assembly includes a cylinder having a first end and a second end. The first and second ends are open. A first perimeter flange is attached to an outer surface of the cylinder and abuts the first end. A second perimeter flange is attached to the outer surface of the cylinder and abuts the second end. A plurality of raised sections is attached to the outer surface and extends between the first and second flanges. Each of the raised sections is positionable in one of the elongated cavities. The first flange has a plurality of elongated wells extending therein. The wells each extend through one of the elongated raised sections and outwardly of the second flange. The cylinder has a break therein that extends through the raised sections so that a first portion and a second portion of the cylinder are defined. Each of plurality of fasteners is removably extendable through one of the elongated cavities and securing the first portion to the second portion when each of the first and second flanges is abutted against one of the first and second side edges of the ring. An axle is extended through the cylinder such that the cylinder is rotatably mounted on the axle. The axle is secured to the inline skate.
There has thus been outlined, rather broadly, the more important features of the invention 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 invention that will be described hereinafter and which will form the subject matter of the claims appended hereto.
The objects of the invention, along with the various features of novelty which characterize the invention, are pointed out with particularity in the claims annexed to and forming a part of this disclosure.
The invention 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
A hub assembly 30 is configured to be removably attached to the loop 12. The hub assembly 30 includes a cylinder 31 that has a first end 32 and a second end 33. The first 32 and second 33 ends are open. A first perimeter flange 34 is attached to an outer surface 37 of the cylinder 31 and abuts the first end 32. A second perimeter flange 35 is attached to the outer surface 37 of the cylinder 31 and abuts the second end 33. A plurality of raised sections 36 is attached to the outer surface 37 and extends between the first 34 and second 35 flanges. Each of the raised sections 36 is positionable in one of the elongated cavities 23. The first flange 34 has plurality of an elongated wells 38 extending therein. Each of the wells 38 extends through one of the elongated raised sections 36 and outwardly of the second flange 35. The cylinder 31 has a break 39 therein that extends through the raised sections 36 so that a first portion 41 and a second portion 42 of the cylinder 31 is defined. Each of the first 41 and second 42 portions has a distal edge 43 with respect to the first 34 and second 35 flanges. An inwardly extending first perimeter lip 44 is attached to the distal edge 43 of the first portion 41 and an inwardly extending second perimeter lip 45 is attached to the distal edge 43 of the second portion 42.
A plurality of fasteners 50 is provided. Each of the fasteners 50 is removably extendable through one of the elongated cavities 38 and secures the first portion 41 to the second portion 42 when each of the first 34 and second 35 flanges is abutted against one of the first 19 and second 20 side edges of the ring 18. The first 19 and second 20 flanges preferably have a same depth as a distance from the first 19 and second 20 side edges of the ring 18 to the first 16 and second 17 lateral sides of the loop 12. The fasteners 50 each preferably include a hex bolt 51 and a threaded rod 52. The portion of the cavity 38 in the section portion may have a same size and shape as the hex bolt 51 to prevent rotation of the hex bolt 51.
A plurality of posts 60 is provided. Each of the posts 50 is attached to the first flange 34 and extends toward and through the second flange 35 when the first 41 and second 42 portions are secured together. Each of the posts 60 is extendable through one of the apertures 24. The posts 60 each have an outer side 61, an inner side 62 and a pair of lateral edges 63. Each of the outer 61 and inner 62 sides is arcuate and each of the apertures 24 has same shape and size as the posts 60. The outer sides 61 are preferably convex while the inner sides 62 are preferably concave. This shape adds strength and stability to the cylinder 31 when it is attached to the ring 18.
In use, an axle 70 is extended through the cylinder 31 so that the cylinder 31 is rotatably mounted on the axle 70. The axle 31 is secured to the inline skate track 71 and is positioned in a pair of annular saddles 72, each having bearings therein, that sit within the cylinder 31 and are abuttable against the first 44 and second 45 perimeter lips. When the loop 12, or wheel, wears out, the hub assembly 30 may be removed and inserted into a new loop 12.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, 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 the present invention.
Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention 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 invention.
