Abstract
Abstract A wheel for a toy vehicle has a device whereby the wheel can be releasably and coaxially attached to a hub mounted on an axle of the toy vehicle and/or to another wheel by way of a bayonet coupling so that wheels can be easily added or removed to increase or decrease the number of wheels on any axle or to interchange wheels with different tire treads. The coupling device is supported relative to a rim of the wheel so as to be coaxial therewith and angularly movable relative thereto. The coupling device has a part on an outer side of the wheel for enabling the coupling device to be turned angularly and a first part of the bayonet coupling on the inner side of the wheel. The second part of the bayonet coupling is provided on the hub and/or a like wheel.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
142 words
A wheel for a toy vehicle, comprising a coupling device for releasably and coaxially attaching the wheel to a hub mounted on an axle of a toy vehicle or to another wheel, the coupling device being supported relative to a rim of the wheel so as to be coaxial therewith and angularly movable relative thereto, the coupling device having a part on an outer side of the wheel for enabling the coupling device to be turned angularly, and a first part of a bayonet coupling on the inner side of the wheel for co-operating with a second part of a bayonet coupling on said hub or said another wheel, the wheel having a said second part of a bayonet coupling on the outer side of the wheel for co-operating with a said first part of a bayonet coupling on a like wheel.
Claim 2
Dependent Claim
142 words
A wheel for a toy vehicle, comprising a coupling device for releasably and coaxially attaching the wheel to a hub mounted on an axle of a toy vehicle or to another wheel, the coupling device being supported relative to a rim of the wheel so as to be coaxial therewith and angularly movable relative thereto, the coupling device having a part on an outer side of the wheel for enabling the coupling device to be turned angularly, and a first part of a bayonet coupling on the inner side of the wheel for co-operating with a second part of a bayonet coupling on said hub or said another wheel, the wheel having a said second part of a bayonet coupling on the outer side of the wheel for co-operating with a said first part of a bayonet coupling on a like wheel.
Claim 3
Dependent Claim
33 words
The wheel of claim 1, wherein the first part of the bayonet coupling comprises a plurality of angularly spaced projections for cooperating with complementary bayonet slots on said hub or said another wheel.
Claim 4
Dependent Claim
46 words
The wheel of claim 2, wherein each projection is provided with one of a protrusion and a recess which extends transversely to a plane of the projections for co-operating with a corresponding one of a recess and protrusion in a part defining a respective bayonet slot.
Claim 5
Dependent Claim
50 words
The wheel of claim 2, wherein the first part of the bayonet coupling comprises a cup-shaped member having a cylindrical wall and an outwardly projecting flange abutting against the inner surface of the wheel, the flange having a generally polygonal peripheral edge having corner portions which define the aforesaid projections.
Claim 6
Dependent Claim
36 words
The wheel of claim 1, wherein the coupling device is capable of limited axial movement relative to the wheel and wherein resilient means are provided to urgee the coupling device towards an outer limit position thereof.
Claim 7
Dependent Claim
55 words
The wheel of claim 1, wherein the first part of the bayonet coupling comprises a plurality of angularly spaced projections and wherein the said second part of the bayonet coupling comprises a plurality of angularly spaced bayonet slots equal in number to the number of projections on the said first part of the bayonet coupling.
Claim 8
Dependent Claim
44 words
The wheel of claim 1, further comprising a hub adapted to be mounted on an axle of a toy vehicle, the hub having a said second part of a bayonet coupling for co-operating with the first part of a bayonet coupling on the wheel.
Claim 9
Dependent Claim
54 words
The combination of claim 7, wherein the first part of the bayonet coupling comprises a plurality of angularly spaced projections and wherein the second part of the bayonet coupling comprises a plurality of angularly spaced bayonet slots equal in number to the number of projections on the said first part of the bayonet coupling.
Claim 10
Dependent Claim
109 words
A wheel for a toy vehicle, comprising a coupling device for releasably and coaxially attaching the wheel to a hub mounted on an axle of a toy vehicle or to another wheel, the coupling device being coaxial with a rim of the wheel and having a first part of a bayonet coupling on an inner side of the wheel for co-operating with a second part of a bayonet coupling on said hub or said another wheel, the wheel having a said second part of a bayonet coupling on the outer side of the wheel for co-operating with a said first part of a bayonet coupling on a like wheel.
Claim 11
Dependent Claim
109 words
A wheel for a toy vehicle, comprising a coupling device for releasably and coaxially attaching the wheel to a hub mounted on an axle of a toy vehicle or to another wheel, the coupling device being coaxial with a rim of the wheel and having a first part of a bayonet coupling on an inner side of the wheel for co-operating with a second part of a bayonet coupling on said hub or said another wheel, the wheel having a said second part of a bayonet coupling on the outer side of the wheel for co-operating with a said first part of a bayonet coupling on a like wheel.
Claim 12
Dependent Claim
33 words
