Abstract
Abstract A wheel having an inflatable tire and designed to be used on automobiles, airplanes, trucks, and the like. The tire has an outer wall provided with an outer tread surface and surrounding a predetermined axis, this outer wall having a pair of opposed side edge regions from which a pair of side walls extend integrally from the outer wall inwardly toward the axis and terminate in inner peripheral edges which surround the axis. An intermediate wall is integral with the outer wall and is situated between and spaced from the side walls, also extending inwardly toward the axis so as to define with the outer walls a pair of air chambers which are separated from each other by the intermediate wall. The wheel includes a suitable mounting structure on which the tire is mounted in such a way that fluid-tight seals are provided at the inner peripheral edges of the side and intermediate walls. In this way if the tire should become punctured or lose air pressure for any reason at one of its chambers it will still be capable of providing fully operative service as a result of the air pressure in the other of its chambers.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
314 words
A wheel comprising an inflatable tire having an outer wall surrounding a predetermined axis and having an outer thread surface and a pair of opposed side edge regions, a pair of opposed side walls integral with said outer wall and extending from said side edge regions thereof inwardly toward said axis, said side walls respectively terminating in inner peripheral edges surrounding said axis, and an intermediate wall integral with said outer wall and situated midway between and spaced from said side walls in a plane normal to said axis, said intermediate wall also extending inwardly from said outer wall toward said axis and terminating in an inner peripheral edge surrounding said axis, said intermediate wall having a greater thickness at the region of its inner peripheral edge than at the region of said outer wall and said thickness of said intermediate wall gradually tapering from said inner peripheral edge toward said outer wall, and mounting means for mounting said tire, said mounting means being surrounded by and engaging said tire and said mounting means including a pair of opposed side sealing means and an intermediate sealing means located between said pair of opposed side sealing means, said pair of opposed side sealing means of said mounting means engaging said inner peripheral edges of said side walls for forming fluid-tight connections therewith and said intermediate sealing means of said mounting means engaging said inner peripheral edge of said intermediate wall for forming a fluid-tight connection therewith, whereby said mounting means and said tire form together a pair of air chambers separated by said intermediate wall, said intermediate sealing means of said mounting means defining an annular groove of rectangular cross section in which said intermediate wall is compressed at said inner peripheral edge thereof and at the portion of said intermediate wall which adjoins said intermediate peripheral edge thereof and is situated in said groove.
Claim 2
Dependent Claim
314 words
A wheel comprising an inflatable tire having an outer wall surrounding a predetermined axis and having an outer thread surface and a pair of opposed side edge regions, a pair of opposed side walls integral with said outer wall and extending from said side edge regions thereof inwardly toward said axis, said side walls respectively terminating in inner peripheral edges surrounding said axis, and an intermediate wall integral with said outer wall and situated midway between and spaced from said side walls in a plane normal to said axis, said intermediate wall also extending inwardly from said outer wall toward said axis and terminating in an inner peripheral edge surrounding said axis, said intermediate wall having a greater thickness at the region of its inner peripheral edge than at the region of said outer wall and said thickness of said intermediate wall gradually tapering from said inner peripheral edge toward said outer wall, and mounting means for mounting said tire, said mounting means being surrounded by and engaging said tire and said mounting means including a pair of opposed side sealing means and an intermediate sealing means located between said pair of opposed side sealing means, said pair of opposed side sealing means of said mounting means engaging said inner peripheral edges of said side walls for forming fluid-tight connections therewith and said intermediate sealing means of said mounting means engaging said inner peripheral edge of said intermediate wall for forming a fluid-tight connection therewith, whereby said mounting means and said tire form together a pair of air chambers separated by said intermediate wall, said intermediate sealing means of said mounting means defining an annular groove of rectangular cross section in which said intermediate wall is compressed at said inner peripheral edge thereof and at the portion of said intermediate wall which adjoins said intermediate peripheral edge thereof and is situated in said groove.
Claim 3
Dependent Claim
88 words
The combination of claim 1 and wherein said mounting means is in the form of a split rim having a pair of rim units respectively provided with said side sealing means which engage said inner peripheral edges of said side walls, said mounting means including a connecting means for connecting said rim units together, and said rim units respectively having inner peripheral flanges which when said rim units are connected together by said connecting means define said annular groove receiving said inner peripheral edge of said intermediate wall.
Claim 4
Dependent Claim
32 words
The combination of claim 2 and wherein said rim units engage each other at an interface situated in a plane normal to said axis, said intermediate wall being located in said plane.
Claim 5
Dependent Claim
29 words
The combination of claim 3 and wherein said outer wall is formed with an exterior annular groove of substantially V-shaped cross section having a crest situated in said plane.
Claim 6
Dependent Claim
30 words
The combination of claim 1 and wherein said inner peripheral edge of said intermediate wall is located closer to said axis than said inner peripheral edges of said side walls.
