Abstract
Abstract A tire mounting device utilizing a locking sleeve wherein the sleeve has an inner diameter substantially equal to the outer diameter of the bottom of the rim so as to encircle the rim and a width slightly greater than the internal separation of the tire beads when the latter are applied to the flanges of the rim, the sleeve being provided with a cross channel to permit the passage of an air passage.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
204 words
A device for mounting a tire on a dismountable rim having a bottom portion and first and second opposed flanges in contact along first and second areas of contact with first and second beads of the tire, respectively, the device in an inflated state comprising: deformable, substantially voidless, circumferentially continuous and incompressible sleeve means encircling the rim for being deformed between said first and second beads and for holding said first and second beads of said tire against said first and second flanges, said sleeve means having an opening formed therein for permitting passage of air therethrough; and means positioned in said sleeve means for causing locking engagement of said sleeve means on said bottom portion of said rim, for preserving a constant external diameter of said sleeve means and for securing said first and second beads of said tire between said sleeve means and said first and second flanges, respectively, wherein said means for causing locking engagement of said sleeve means further comprises a circumferentially continuous reinforcement layer positioned in said sleeve means at a radial position which is located radially outward of said area of contact of said first and second opposed flanges with said first and second beads of said tire.
Claim 2
Independent Claim
204 words
A device for mounting a tire on a dismountable rim having a bottom portion and first and second opposed flanges in contact along first and second areas of contact with first and second beads of the tire, respectively, the device in an inflated state comprising: deformable, substantially voidless, circumferentially continuous and incompressible sleeve means encircling the rim for being deformed between said first and second beads and for holding said first and second beads of said tire against said first and second flanges, said sleeve means having an opening formed therein for permitting passage of air therethrough; and means positioned in said sleeve means for causing locking engagement of said sleeve means on said bottom portion of said rim, for preserving a constant external diameter of said sleeve means and for securing said first and second beads of said tire between said sleeve means and said first and second flanges, respectively, wherein said means for causing locking engagement of said sleeve means further comprises a circumferentially continuous reinforcement layer positioned in said sleeve means at a radial position which is located radially outward of said area of contact of said first and second opposed flanges with said first and second beads of said tire.
Claim 3
Dependent Claim
18 words
A device according to claim 1, wherein said reinforcement layer further comprises a belt-type layer of corded fabric.
Claim 4
Independent Claim
41 words
A device according to claims 1 or 2, wherein said sleeve means further comprises a sleeve having a cross-sectional shape with first and second laterally opposed surfaces adapted to the shape of said first and second beads of said tire, respectively.
Claim 5
Dependent Claim
76 words
A device according to claim 3, wherein said sleeve means further comprises a sleeve having a trapezium-shaped cross-section, so as to have a large outer surface and a small inner base, said small inner base being mounted so as to encircle said rim and wherein the mean of the lateral width dimensions of said outer surface and said inner base is approximately seven percent greater than a distance of separation of said first and second beads.
Claim 6
Dependent Claim

Claim 8
Independent Claim
74 words
A device according to claims 1 or 2, further comprising an air passage means and a fastening boss attached to said rim for connecting said air passage means to said rim wherein said sleeve means has a small inner base and a central groove formed in said small inner base for housing said fastening boss, said groove communicating with an inner space portion of said tire via said opening formed in said sleeve means.
Claim 9
Dependent Claim
31 words
A device according to claim 7, wherein said air passage means includes a radial section at least in the vicinity of first and second opposite lateral surfaces of said sleeve means.
Claim 10
Independent Claim
22 words

Claim 15
Dependent Claim
32 words
A device according to claim 1, wherein said sleeve means further comprises a sleeve of homogeneous composition and wherein said reinforcement layer is positioned at an upper portion of said sleeve means.
Claim 16
Dependent Claim
38 words
A device according to claim 1, wherein said reinforcement layer further comprises an axially continuous reinforcement layer positioned at an upper portion of said sleeve means and wherein said sleeve means further comprises a sleeve of homogeneous composition.
Claim 17
Dependent Claim
28 words
A device according to claim 1, wherein the width dimension of said sleeve is greater than an internal spacing of said first and second beads of said tire.
