Adjustable strap

Claim 2

An adjustable strap connectable between spaced points, comprising: an elongated elastomeric belt means, means located effectively at the ends of said belt means for connecting said belt means to said spaced points, first and second buckles including transverse cross bars defining first, second, and third slots to receive said belt means for engagement of said cross bars with first and second spaced-apart portions of said belt means in a substantially no-slip condition that includes said belt means passing through said first slot and back through said second slot at each of said buckles, the intermediate portion of said belt means between said first and second portions passing alternately through the third slot of first one buckle and then the other buckle to form a plurality of strands of belt means extending between the first and second buckles whereby each of said slots receives a single strand of said belt means, said first and second portions of the belt means being selectively movable relative to said first and second buckles to vary relative spacing of said buckles whereby the effective overall length of said adjustable strap is varied.

Claim 3

An adjustable strap as defined in claim 1 wherein said belt means has a generally rectangular cross section and wherein the base dimension engageable with said cross bars greatly exceeds the thickness dimension.

Claim 4

An adjuStable strap as defined in claim 1 wherein said connecting means is in the form of hooks fixed to the ends of said belt means.

Claim 5

An adjustable strap as defined in claim 1 wherein said belt means is in the form of a unitary strip of polyurethane material.

Claim 6

An adjustable strap connectable between first and second spaced points, the combination comprising: an elongated flat elastomeric belt member, means at the ends of the belt member for connecting said belt member to said first and second spaced points, first and second spaced-apart buckles each having transverse cross bars engageable with said belt member and defining first, second and third slots, said belt member passing through the first slot from a first side of said first buckle and back through the second slot of said first buckle from the second side thereof, said belt member extending to said second buckle and passing through the third slot from said first side and returning to said first buckle to pass through said third slot from said first side, said belt member continuing to said second buckle to pass through said second slot from said second side and back through the first slot of said second buckle from said first side whereby each of the first, second and third slots of both buckles receives a single strand of said belt member in a substantially no-slip engagement with said buckles, said belt member being selectively movable relative to said buckles to vary the relative portion of said belt member between said buckles whereby the effective overall length of said strap is adjustable.

Claim 7

An adjustable strap connectable between first and second spaced points, the combination comprising: an elongated flat elastomeric belt member, means at the ends of the belt member for connecting said belt member to said first and second spaced points, first and second spaced-apart buckles each having transverse cross bars engageable with said belt member and defining first, second and third slots, said belt member passing through the first slot from a first side of said first buckle and back through the second slot of said first buckle from the second side thereof, said belt member extending to said second buckle and passing through the third slot from said first side and returning to said first buckle to pass through said third slot from said first side, said belt member continuing to said second buckle to pass through said second slot from said second side and back through the first slot of said second buckle from said first side whereby each of the first, second and third slots of both buckles receives a single strand of said belt member in a substantially no-slip engagement with said buckles, said belt member being selectively movable relative to said buckles to vary the relative portion of said belt member between said buckles whereby the effective overall length of said strap is adjustable.

Claim 8

An adjustable strap as defined in claim 5 wherein said flat belt member is in the form of a unitary strip of polyurethane material and wherein said adjustable strap is resiliently connectable between said spaced attachment points to maintain said adjustable strap under tension.

Claim 9

An adjustable strap as defined in claim 5 wherein said flat belt member is in the form of a unitary strip of polyurethane material and wherein said connecting means includes hooks retained in loops of polyurethane material at the ends of the belt member.
