Abstract

Attachment elements are connected to spaced ends of an elastic cord. A shroud extends the length of the cord between the attachment elements and is affixed to the attachment elements. The shroud is a tubular-shaped member forming a plurality of pleats when the elastic cord is in unelongated condition. When the elastic cord is elongated and the shroud is unpleated it provides a positive restraint against further stretching of the elastic cord.

Claims7

Dependent claims

In combination:

an elastic cord having spaced ends;
an attachment element at each of said elastic cord ends for attaching said elastic cord ends to relatively moveable objects, movement of said objects away from each other stretching said elastic cord;
shroud means wholly covering said elastic cord, extending between said attachment elements, and affixed to said attachment elements, said shroud means comprising flexible generally tubular-shaped member extending along the full length of said elastic rod and forming a plurality of pleats when said elastic cord is in the elongated condition, said generally tubular-shaped member being formed of woven fabric material which becomes unpleated when said objects are moved away from each other a predetermined distance, and said generally tubular-shaped member operable upon unpleating thereof to positively prevent said objects from moving substantially further apart than said predetermined distance, said generally tubular-shaped member being unaffixed to the elastic cord along the full length of said elastic cord whereby stretching of said elastic cord will not be impeded by said generally tubular-shaped member until the objects have moved said predetermined distance, at least one of said attachment elements comprising a strap affixed to an end of said elastic cord and forming a loop projecting from said elastic cord end and having overlapping strap portions, said generally tubular-shaped member partially covering said strap and affixed thereto by stitching passing through both said overlapping portions of said strap and through said generally tubular-shaped member on opposed sides of said strap to close the end of said as generally tubular-shaped member, said stitching big spaced outwardly away from the end of said elastic cord to which said strap is affixed, said elastic cord being doubled back on itself to form engaging cord segments defining a bight at each said elastic cord end and additionally comprising fastener means disposed about said engaging cord segments for maintaining said bight, said attachment elements being connected t said bights.

Dependencies are inferred from the claim text.
