Load bearing fabric attachment and associated method
View Patent ↗An attachment structure for a load bearing fabric. The attachment structure includes interfitted inner and outer rings. The outer ring includes a fabric leg 74 carrying a load bearing fabric. The inner ring defines a channel receiving the fabric leg 74 . The inner ring and outer ring are configured to stretch the fabric upon insertion of the fabric leg 74 into the channel. The present invention also provides a method for securing a load bearing fabric to a support structure, generally including the steps of (a) providing an outer ring having fabric leg 74 , (b) attaching a section of load bearing fabric to the fabric leg 74 , (c) providing an inner ring having a channel adapted to receive the leg of the outer ring and (d) installing the outer ring to the inner ring by inserting the leg into the channel, the insertion forcing the fabric down into the channel and stretching the fabric to the desired tension.
1. An assembly comprising:
a load bearing fabric having a periphery;
a first ring secured about said periphery of said fabric, said first ring having an inner surface facing toward said fabric, said fabric secured to said first ring at said inner surface, wherein said first ring and said fabric are integral, said first ring being molded in place about said fabric, wherein said first ring is substantially L-shaped having a fabric leg and a trim leg, said fabric leg extending in said direction substantially perpendicular to said remainder of said fabric, said fabric leg defining said inner surface;
a second ring mounted within said first ring to engage and stretch said fabric, said second ring extending along said inner surface and directly engaging a portion of said fabric such that said portion of said fabric is forced to extend in a direction at an angle to a remainder of said fabric, whereby said second ring stretches said fabric to a desired tension, wherein said second ring defines a channel opening in a direction substantially perpendicular to said remainder of said fabric, said first ring being fitted within said channel, whereby said portion of said fabric is forced to extend in said direction perpendicular to said remainder of said fabric;
securing means for intersecuring said first ring and said second ring to maintain said fabric at said desired tension; and
a support structure, said second ring being secured to said support structure.
2. An assembly comprising:
a load bearing fabric having a periphery;
a first ring secured about said periphery of said fabric, said first ring having an inner surface facing toward said fabric, said fabric secured to said first ring at said inner surface, wherein said first ring and said fabric are integral, said first ring being molded in place about said fabric, wherein said first ring is substantially L-shaped having a fabric leg and a trim leg, said fabric leg extending in said direction substantially perpendicular to said remainder of said fabric, said fabric leg defining said inner surface, wherein said fabric is secured to said fabric leg at different locations in different regions of said first ring to selectively control said portion of said fabric extending in said direction perpendicular to said remainder of said fabric;
a second ring mounted within said first ring to engage and stretch said fabric, said second ring extending along said inner surface and directly engaging a portion of said fabric such that said portion of said fabric is forced to extend in a direction at an angle to a remainder of said fabric, whereby said second ring stretches said fabric to a desired tension, wherein said second ring defines a channel opening in a direction substantially perpendicular to said remainder of said fabric, said first ring being fitted within said channel, whereby said portion of said fabric is forced to extend in said direction perpendicular to said remainder of said fabric;
securing means for intersecuring said first ring and said second ring to maintain said fabric at said desired tension; and
a support structure, said second ring being secured to said support structure.
3. An assembly comprising:
a load bearing fabric having a periphery;
a first ring secured about said periphery of said fabric, said first ring having an inner surface facing toward said fabric, said fabric secured to said first ring at said inner surface, wherein said first ring and said fabric are integral, said first ring being molded in place about said fabric, wherein said first ring is substantially L-shaped having a fabric leg and a trim leg, said fabric leg extending in said direction substantially perpendicular to said remainder of said fabric, said fabric leg defining said inner surface, wherein said fabric is secured to said fabric leg at different locations in different regions of said first ring to selectively control said portion of said fabric extending in said direction perpendicular to said remainder of said fabric;
a second ring mounted within said first ring to engage and stretch said fabric, said second ring extending along said inner surface and directly engaging a portion of said fabric such that said portion of said fabric is forced to extend in a direction at an angle to a remainder of said fabric, whereby said second ring stretches said fabric to a desired tension, wherein said second ring defines a channel opening in a direction substantially perpendicular to said remainder of said fabric, said first ring being fitted within said channel, whereby said portion of said fabric is forced to extend in said direction perpendicular to said remainder of said fabric, wherein at least one of said first ring and said second ring includes integral interlocking tabs intersecuring said first ring and said second ring;
securing means for intersecuring said first ring and said second ring to maintain said fabric at said desired tension; and
a support structure, said second ring being secured to said support structure.
4. The assembly of claim 3 wherein said first ring is rigid, being substantially nonexpendable.
