Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
140 words
A unit sole construction, comprising a sole body of molded, rubbery material, having a central top surface for receipt of an upper and a peripheral top surface for receipt of a welt, and a welt extending along the perimeter of said body, said welt comprising an exposed upper wall portion arranged to cover said peripheral top surface of said sole, and a tongue portion extending from said wall portion into said body, a tongue being embedded in said body so as to be wholly surrounded by said rubbery material to secure said welt thereto prior to attachment of said upper to said surface, said welt being free of encroachment onto said central top surface of said sole, so as to avoid reduction of bonding area between said upper and said sole, said welt being free of stitching to said upper.
Claim 2
Dependent Claim
140 words
A unit sole construction, comprising a sole body of molded, rubbery material, having a central top surface for receipt of an upper and a peripheral top surface for receipt of a welt, and a welt extending along the perimeter of said body, said welt comprising an exposed upper wall portion arranged to cover said peripheral top surface of said sole, and a tongue portion extending from said wall portion into said body, a tongue being embedded in said body so as to be wholly surrounded by said rubbery material to secure said welt thereto prior to attachment of said upper to said surface, said welt being free of encroachment onto said central top surface of said sole, so as to avoid reduction of bonding area between said upper and said sole, said welt being free of stitching to said upper.
Claim 3
Dependent Claim
18 words
The sole construction of claim 1, wherein said tongue extends from the inner periphery of said wall portion.
Claim 4
Dependent Claim
43 words
The sole construction of claim 2 wherein said welt further comprises an exposed flange portion extending from the outer periphery of said wall portion so as to give said welt a J-shaped cross-section with said flange forming the short leg of said J.
Claim 5
Dependent Claim
27 words
The sole construction of claim 1 or 3 wherein said tongue portion has a perforation therethrough, and said rubbery material of said body extends into said perforation.
Claim 6
Dependent Claim

Claim 12
Independent Claim
148 words
A method of manufacturing a unit sole construction, said construction comprising a sole body of molded, rubbery material, having a central top surface for receipt of an upper and a peripheral top surface for receipt of a welt, and a welt extending along the perimeter of said body, said welt comprising an exposed upper wall portion arranged to cover said peripheral top surface of said sole, and a tongue portion extending from said wall portion into said body, said method comprising the steps of molding said body around said tongue so as to cause said tongue to be wholly surrounded by said rubbery material to secure said welt thereto prior to attachment of said upper to said surface, and said welt to be free of encroachment onto said central top surface of said sole, so as to avoid reduction of bonding area between said upper and said sole.
Claim 13
Independent Claim
148 words
A method of manufacturing a unit sole construction, said construction comprising a sole body of molded, rubbery material, having a central top surface for receipt of an upper and a peripheral top surface for receipt of a welt, and a welt extending along the perimeter of said body, said welt comprising an exposed upper wall portion arranged to cover said peripheral top surface of said sole, and a tongue portion extending from said wall portion into said body, said method comprising the steps of molding said body around said tongue so as to cause said tongue to be wholly surrounded by said rubbery material to secure said welt thereto prior to attachment of said upper to said surface, and said welt to be free of encroachment onto said central top surface of said sole, so as to avoid reduction of bonding area between said upper and said sole.
Claim 14
Dependent Claim
47 words
The method of claim 11 further comprising the steps of providing a mold having a groove around the periphery thereof adapted to receive said welt, positioning said welt in said groove, and injecting rubbery material into said mold to form said sole body and embed said tongue.
Claim 15
Dependent Claim
57 words
The method of claim 12 further comprising the steps of providing a mold having a groove around the periphery thereof adapted to receive said welt, coating said surfaces of said welt with an adhesive and positioning said welt in said groove, and injecting rubbery material into said mold to form said sole body and embed said tongue.
