Abstract
Abstract A pneumatic or semi-pneumatic unitary tire-wheel comprising a completely enclosed toroidal chamber bonded around a coaxial inner sleeve. A plurality of tie members are integral with and extend between the sidewalls to restrict lateral deformation thereof. Such reinforcing tie members may be hollow to give the appearance of openings between wheel spokes.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
215 words
A one-piece inflatable tire-wheel having a pneumatic tire portion including a crown portion and a pair of spaced apart sidewalls which cooperatively define a toroidal air chamber coextendant thereabout, a wheel portion including a central hub and a pair of spaced apart sidewalls, each of said sidewalls of said wheel portion being integral with one of said sidewalls of said tire portion and extending therefrom to said central hub and being integral with said central hub, said sidewalls of said wheel portion defining a continuous air chamber therewithin and interconnecting said central hub and said pneumatic tire portion as a unitary one-piece tire-wheel, said air chamber of said tire portion opening into said air chamber of said wheel portion and providing unitary and continuous inflatable air chamber means within said tire-wheel for receiving pneumatic pressurization in maintaining the structural integrity of said tire-wheel to provide a pneumatically sustained tire-wheel, said wheel portion including a plurality of hollow structural reinforcing tie members disposed intermediate said central hub and said pneumatic tire portion, said tie members including wall portions integral with and extending between said sidewalls of said wheel portion in a manner to restrict lateral deformation thereof, and valve means for inflation of said air chamber means of said inflatable tire-wheel to the desired pneumatic pressure.
Claim 2
Dependent Claim
215 words
A one-piece inflatable tire-wheel having a pneumatic tire portion including a crown portion and a pair of spaced apart sidewalls which cooperatively define a toroidal air chamber coextendant thereabout, a wheel portion including a central hub and a pair of spaced apart sidewalls, each of said sidewalls of said wheel portion being integral with one of said sidewalls of said tire portion and extending therefrom to said central hub and being integral with said central hub, said sidewalls of said wheel portion defining a continuous air chamber therewithin and interconnecting said central hub and said pneumatic tire portion as a unitary one-piece tire-wheel, said air chamber of said tire portion opening into said air chamber of said wheel portion and providing unitary and continuous inflatable air chamber means within said tire-wheel for receiving pneumatic pressurization in maintaining the structural integrity of said tire-wheel to provide a pneumatically sustained tire-wheel, said wheel portion including a plurality of hollow structural reinforcing tie members disposed intermediate said central hub and said pneumatic tire portion, said tie members including wall portions integral with and extending between said sidewalls of said wheel portion in a manner to restrict lateral deformation thereof, and valve means for inflation of said air chamber means of said inflatable tire-wheel to the desired pneumatic pressure.
Claim 3
Dependent Claim
13 words
The tire member defined by claim 1 wherein: said tie members are tubular.
Claim 4
Dependent Claim
24 words
The tire member defined by claim 1 wherein: said tie members are tubular and disposed to coincide with the bolting on a vehicle hub.
Claim 5
Dependent Claim
31 words
The tire member defined by claim 1 wherein: said tie members are tubular and are configurated and disposed so that the inner side wall portions between them appear as wheel spokes.
Claim 6
Dependent Claim
52 words
A one-piece inflatable tire-wheel as specified in claim 1 wherein said side walls of said pneumatic tire portion are spaced apart substantially the width of said tread portion and said sidewalls of said wheel portion are more closely positioned together than said sidewalls of said tire portion in simulation of a wheel.
Claim 7
Dependent Claim
215 words
A one-piece, molded, inflatable tire-wheel having a pneumatic tire portion including a crown portion and a pair of spaced apart sidewalls which cooperatively define a toroidal air chamber coextendant thereabout, a wheel portion comprising a hub for said tire portion, said wheel portion including a pair of spaced apart sidewalls, each of said sidewalls of said wheel portion being integral with one of said sidewalls of said tire portion, said sidewalls of said wheel portion defining a continuous air chamber within said wheel portion and interconnecting said tire portion and wheel portion as a unitary one-piece tire-wheel, and a plurality of hollow structural reinforcing tie members spaced apart within said wheel portion, each said tie members including wall portions integral with and extending between said sidewalls of said wheel portion in a manner to restrict lateral deformation thereof, said air chamber of said tire portion opening into said air chamber of said wheel portion and providing unitary and continuous inflatable air chamber means within said tire wheel for receiving pneumatic pressurization in maintaining the structural integrity of said tire-wheel to provide a pneumatically sustained tire-wheel, means for interconnection of said tire wheel to an axle means, and valve means for inflation of said air chamber means of said inflatable tire-wheel to the desired pneumatic pressure.
Claim 8
Dependent Claim
215 words
A one-piece, molded, inflatable tire-wheel having a pneumatic tire portion including a crown portion and a pair of spaced apart sidewalls which cooperatively define a toroidal air chamber coextendant thereabout, a wheel portion comprising a hub for said tire portion, said wheel portion including a pair of spaced apart sidewalls, each of said sidewalls of said wheel portion being integral with one of said sidewalls of said tire portion, said sidewalls of said wheel portion defining a continuous air chamber within said wheel portion and interconnecting said tire portion and wheel portion as a unitary one-piece tire-wheel, and a plurality of hollow structural reinforcing tie members spaced apart within said wheel portion, each said tie members including wall portions integral with and extending between said sidewalls of said wheel portion in a manner to restrict lateral deformation thereof, said air chamber of said tire portion opening into said air chamber of said wheel portion and providing unitary and continuous inflatable air chamber means within said tire wheel for receiving pneumatic pressurization in maintaining the structural integrity of said tire-wheel to provide a pneumatically sustained tire-wheel, means for interconnection of said tire wheel to an axle means, and valve means for inflation of said air chamber means of said inflatable tire-wheel to the desired pneumatic pressure.
