Abstract

Abstract A carrying strap comprises a resilient foam padding layer sandwiched between inner and outer surface strips of soft pliable simulated leather material, with an inner load-bearing layer of tightly woven high-strength webbing extending across the full width of the strap between the foam padding and the outer surface layer. Side edge caps enclose the side edge portions of the surface layers and webbing, and side stitching secures the caps, surface layers and webbing together throughout the length of the strap. The opposite ends of the strap are attached to a carrying bag by a pair of side-by-side rivets extending through the surface layers and webbing of the strap, through the bag material and through a leather backing patch on the inside surface of the bag material. Cross-stitching through the strap ends, bag and backing patch below the rivets prevents the strap from twisting on the rivets.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 254 words
A carrying strap construction comprising: a first thin, soft, pliable strip forming a first surface layer of said strap; a second thin, soft, pliable strip overlying said first strip and forming a second surface layer of said strap; a resilient layer of padding material of greater thickness than said surface layers sandwiched between said surface layers; a thin, flexible strip of high-strength material resistant to stretching forming an inner load-bearing layer of said strap between said resilient layer and one of said surface layers and extending across the full width of said padding layer; and stitching extending through said first and second surface layers and said load-bearing inner layer at the opposite side edge portions of said strap and along the length thereof to stitch together said surface and inner layers and enclose said layer of padding; at least one end portion of said strap being fastened to a carrying bag by attachment means comprising at least two side-by-side rivets extending through both said surface layers and said load-bearing inner layer and through the material of said bag and through a backing patch member on an inside surface portion of said bag material with said rivets compressing the aforesaid layers of strap and bag between the opposite enlarged ends thereof; and cross-stitching extending across the width of said strap and through said surface and inner layers of said strap and through said bag material and said backing patch at a position on said strap spaced toward the end of said strap from said rivets.
Claim 2
Dependent Claim 254 words
A carrying strap construction comprising: a first thin, soft, pliable strip forming a first surface layer of said strap; a second thin, soft, pliable strip overlying said first strip and forming a second surface layer of said strap; a resilient layer of padding material of greater thickness than said surface layers sandwiched between said surface layers; a thin, flexible strip of high-strength material resistant to stretching forming an inner load-bearing layer of said strap between said resilient layer and one of said surface layers and extending across the full width of said padding layer; and stitching extending through said first and second surface layers and said load-bearing inner layer at the opposite side edge portions of said strap and along the length thereof to stitch together said surface and inner layers and enclose said layer of padding; at least one end portion of said strap being fastened to a carrying bag by attachment means comprising at least two side-by-side rivets extending through both said surface layers and said load-bearing inner layer and through the material of said bag and through a backing patch member on an inside surface portion of said bag material with said rivets compressing the aforesaid layers of strap and bag between the opposite enlarged ends thereof; and cross-stitching extending across the width of said strap and through said surface and inner layers of said strap and through said bag material and said backing patch at a position on said strap spaced toward the end of said strap from said rivets.
Claim 3
Dependent Claim 99 words
A construction according to claim 1 wherein both said surface layers and said bag material comprise a vinyl material and wherein edge caps of vinyl material enclose opposite side edge portions of said strap in overlying relationship to said surface layers throughout the length of said strap, said stitching extending through said edge caps, surface layers and inner layer of said strap throughout the length thereof to fasten said strap surface layers and caps together and cause said high-strength inner layer to extend substantially flat across the full width of said strap, said rivets extending through said edge caps.
Claim 4
Dependent Claim 18 words
A construction according to clAim 1 wherein said backing patch member comprises a monolithic full thickness of leather.
Claim 5
Dependent Claim 22 words
A construction according to claim 1 wherein said backing patch member is bonded to said inside surface portion of said bag material.
Claim 6
Dependent Claim 195 words
A carrying strap construction comprising: a first thin, soft, pliable strip forming a first surface layer of said strap; a second thin, soft, pliable strip overlying said first strip and forming a second surface layer of said strap; a thin, flexible strip of high-strength material resistant to stretching forming an inner load-bearing layer of said strap between said first and second surface layers; at least one end portion of said strap including said first and second surface layers and said inner layer being fastened to a carrying bag by attachment means comprising at least two sideby-side rivets, extending through said surface layers and said load-bearing inner layer and through the material of said bag and through a backing patch member on an inside surface portion of said bag material with said rivets compressing the aforesaid layers of said strap and bag between the opposite enlarged ends of said rivets; and cross-stitching extending across the width of said strap end portion and through said surface and inner layers of said strap and through said bag material and said backing member at a position on said strap spaced toward the end of said strap from said rivets.
Claim 7
Dependent Claim 195 words
A carrying strap construction comprising: a first thin, soft, pliable strip forming a first surface layer of said strap; a second thin, soft, pliable strip overlying said first strip and forming a second surface layer of said strap; a thin, flexible strip of high-strength material resistant to stretching forming an inner load-bearing layer of said strap between said first and second surface layers; at least one end portion of said strap including said first and second surface layers and said inner layer being fastened to a carrying bag by attachment means comprising at least two sideby-side rivets, extending through said surface layers and said load-bearing inner layer and through the material of said bag and through a backing patch member on an inside surface portion of said bag material with said rivets compressing the aforesaid layers of said strap and bag between the opposite enlarged ends of said rivets; and cross-stitching extending across the width of said strap end portion and through said surface and inner layers of said strap and through said bag material and said backing member at a position on said strap spaced toward the end of said strap from said rivets.
Claim 8
Dependent Claim 31 words
A strap construction according to claim 5 wherein said first and second surface layers of said strap are composed of vinyl material and said backing patch member is composed of leather.
