Abstract
Abstract A recreational device includes an outer hoop to which a generally axially disposed hub is secured by radial spokes. The hub includes a discoid portion and a generally cylindrical wall defining a recess so that the device can be spun on the tip of a stick. An axial hole in the hub allows two of the devices to be mounted on a shaft to provide a pair of wheels while, by detaching the hub and the spokes from the hoop, the device is converted into a conventional trundling hoop. By the use of generally trapezoidal vanes having airfoil configurations as the spokes, the device can be caused to fly through the air when spun from the tip of a stick or, by inverting the device, it tends to remain on the tip of such a stick when it is spun thereon.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
236 words
In a recreational device, the combination of a wheel comprising a hoop defined by inner and outer peripheral surfaces, a generally axially disposed hub and a plurality of spokes extending outwardly from said hub and detachably connected to said hoop inwardly of said outer peripheral surface thereof by resiliently deformable securement means for maintaining said hub in generally axial disposition relative to said hoop, and in which said hub includes an annular discoid portion defining a generally axial opening and depending from said annular discoid portion a continuous outer skirt wall defining a generally cylindrical axial recess, and an elongated playing stick comprising a reduced diameter terminal portion defined by a radially extending shoulder and dimensioned freely to be received in said generally axial opening in said discoid portion of said hub for essentially non-eccentric rotation of said wheel on said playing stick and said playing stick having a terminal portion dimensioned to be received in said axial recess in said hub so as to engage said annular discoid portion of said hub outwardly of said axial opening therethrough thereby to support said wheel on that end of said playing stick and whereby, in turn, said wheel can be spun eccentrically on said playing stick, and whereby, on detachment of said spokes from said hoop and on removal of said hub and said spokes from said hoop, that hoop can be used as a trundling hoop.
Claim 2
Dependent Claim

In a recreational device, the combination of a wheel comprising a hoop defined by inner and outer peripheral surfaces, a generally axially disposed hub and a plurality of spokes extending outwardly from said hub and detachably connected to said hoop inwardly of said outer peripheral surface thereof by resiliently deformable securement means for maintaining said hub in generally axial disposition relative to said hoop, and in which said hub includes an annular discoid portion defining a generally axial opening and depending from said annular discoid portion a continuous outer skirt wall defining a generally cylindrical axial recess, and an elongated playing stick comprising a reduced diameter terminal portion defined by a radially extending shoulder and dimensioned freely to be received in said generally axial opening in said discoid portion of said hub for essentially non-eccentric rotation of said wheel on said playing stick and said playing stick having a terminal portion dimensioned to be received in said axial recess in said hub so as to engage said annular discoid portion of said hub outwardly of said axial opening therethrough thereby to support said wheel on that end of said playing stick and whereby, in turn, said wheel can be spun eccentrically on said playing stick, and whereby, on detachment of said spokes from said hoop and on removal of said hub and said spokes from said hoop, that hoop can be used as a trundling hoop.
Claim 3
Dependent Claim
35 words
A recreational device as claimed in claim 1 and in which said peripheral outer surface of said hoop is formed with a generally central peripherally extending recess for receiving a tip of said playing stick.
Claim 4
Dependent Claim
38 words
A recreational device as claimed in claim 1 and in which said resiliently deformable securement means comprises resiliently deformable members provided at outer ends of said spokes for detachable securement to co-operating securement means provided on said hoop.
Claim 5
Dependent Claim
58 words
A recreational device as claimed in claim 1 in which each said spoke is defined by lateral edges which diverge in the radially outward direction and in which each said spoke has an airfoil configuration with one major surface thereof disposed obliquely relative to the major plane of said hoop when said spokes are attached to said hoop.
Claim 6
Dependent Claim
43 words
A recreational device as claimed in claim 4 and in which said discoid portion of said hub is integrally formed with a generally cylindrical outer wall thereby to define two said generally cylindrical axial recesses, one on each side of said discoid portion.
Claim 7
Dependent Claim
53 words
A recreational device as claimed in claim 3 and in which said hub and said spokes are integrally formed of a resiliently flexible plastics material and in which said resiliently deformable members comprise studs formed at the radially outer ends of said spokes and removably received within corresponding recesses formed in said hoop.
