Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
112 words
A reinforced resilient wheel having: an annular tire rim, a hub within the rim, an annular channel of generally U-shaped cross-section on the inner side of the rim and facing the hub, a one-piece, annular, elastomeric member engaging the annular channel creating a shock absorbing, sealed, air space defined by the inner surface of the elastomeric member and the inner surface of the U-shaped channel, the hub being connected to the elastomeric member by mechanical fastening means comprising headed fasteners passing through the elastomeric member and secured to the hub, and flange means attached to the rim extending around the edges of the elastomeric member to clamp the member to the rim.
Claim 2
Dependent Claim
112 words
A reinforced resilient wheel having: an annular tire rim, a hub within the rim, an annular channel of generally U-shaped cross-section on the inner side of the rim and facing the hub, a one-piece, annular, elastomeric member engaging the annular channel creating a shock absorbing, sealed, air space defined by the inner surface of the elastomeric member and the inner surface of the U-shaped channel, the hub being connected to the elastomeric member by mechanical fastening means comprising headed fasteners passing through the elastomeric member and secured to the hub, and flange means attached to the rim extending around the edges of the elastomeric member to clamp the member to the rim.
Claim 3
Dependent Claim
40 words
A reinforced resilient wheel in accordance with claim 1 wherein, there is an annular reinforcing member in the form of a hoop on the elastomeric member in the air space and mechanical fastener means connecting the hoop to the hub.
Claim 4
Dependent Claim
33 words
A reinforced resilient wheel in accordance with claim 1 wherein, the securing means include at least two legs each extending in engagement with the elastomeric member to clamp the member to the hub.
Claim 5
Dependent Claim
44 words
A reinforced resilient wheel in accordance with claim 1 wherein the flange means extend toward the hub from opposed directions and terminate without engaging the hub to create a limiting means to restrict lateral deflection of the rim and tire relative to the hub.
Claim 6
Dependent Claim
142 words
A reinforced resilient wheel having: an annular tire rim, a hub within the rim, an annular channel of generally U-shaped cross-section on the inner side of the rim and facing the hub, a one-piece, annular, elastomeric member engaging the annular channel creating a shock absorbing, sealed, air space defined by the inner surface of the elastomeric member and the inner surface of the U-shaped channel, the hub being connected to the elastomeric member by mechanical fastening means comprising headed fasteners passing through the elastomeric member and secured to the hub, and means for securing the elastomeric member to the rim comprising a pair of an annular flanges permanently secured to the rim adjacent the sealed air space, each flange having at least one leg extending around the edges of the elastomeric member in engagement therewith to clamp the member to the rim.
Claim 7
Dependent Claim
142 words
A reinforced resilient wheel having: an annular tire rim, a hub within the rim, an annular channel of generally U-shaped cross-section on the inner side of the rim and facing the hub, a one-piece, annular, elastomeric member engaging the annular channel creating a shock absorbing, sealed, air space defined by the inner surface of the elastomeric member and the inner surface of the U-shaped channel, the hub being connected to the elastomeric member by mechanical fastening means comprising headed fasteners passing through the elastomeric member and secured to the hub, and means for securing the elastomeric member to the rim comprising a pair of an annular flanges permanently secured to the rim adjacent the sealed air space, each flange having at least one leg extending around the edges of the elastomeric member in engagement therewith to clamp the member to the rim.
Claim 8
Dependent Claim
40 words
A reinforced resilient wheel in accordance with claim 5 wherein, there is an annular reinforcing member in the form of a hoop on the elastomeric member in the air space and mechanical fastener means connecting the hoop to the hub.
Claim 9
Dependent Claim
33 words
A reinforced resilient wheel in accordance with claim 5 wherein, the securing means include at least two legs each extending in engagement with the elastomeric member to clamp the member to the hub.
Claim 10
Dependent Claim
44 words
A reinforced resilient wheel in accordance with claim 5 wherein the flange means extend toward the hub from opposed directions and terminate without engaging the hub to create a limiting means to restrict lateral deflection of the rim and tire relative to the hub.
Claim 11
Dependent Claim
140 words
A reinforced resilient wheel having: an annular tire rim, a hub within the rim, an annular channel of generally U-shaped cross-section on the inner side of the rim and facing the hub, a one-piece, annular, elastomeric member engaging the annular channel creating a shock absorbing, sealed, air space defined by the inner surface of the elastomeric member and the inner surface of the U-shaped channel, the hub being connected to the elastomeric member by mechanical fastening means comprising headed fasteners passing through the elastomeric member and secured to the hub, and flange means attached to the rim extending around the edges of the elastomeric member to clamp the member to the rim, an annular reinforcing member in the form of a hoop on the elastomeric member in the air space and mechanical fastener means connecting the hoop to the hub.
Claim 12
Dependent Claim
