Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
154 words
A clamp element to be used in conjunction with three or more similar elements interconnected with at least one adjustable strap comprising: a relatively thick main body portion of an L configuration wherein the legs are the same length and have a substantially uniplanar inner surface, each leg including a longitudinal bore extending the length thereof along the exterior edge and a longitudinal, substantially rectangular slot which slots intersect in a smooth interior arcuate intersection, each leg also including a substantially rectangular slot extending through the leg laterally thereof, said main body portion further including a lateral bore at the intersection of the legs whereby a plurality of elements may be aligned in a three-dimensional array by dowels extending through the bores thereof, said elements likewise being capable of presenting clamping forces in a three-dimensional configuration whereby the device may readily and easily be used to clamp objects in either two or three dimensions.
Claim 2
Dependent Claim
154 words
A clamp element to be used in conjunction with three or more similar elements interconnected with at least one adjustable strap comprising: a relatively thick main body portion of an L configuration wherein the legs are the same length and have a substantially uniplanar inner surface, each leg including a longitudinal bore extending the length thereof along the exterior edge and a longitudinal, substantially rectangular slot which slots intersect in a smooth interior arcuate intersection, each leg also including a substantially rectangular slot extending through the leg laterally thereof, said main body portion further including a lateral bore at the intersection of the legs whereby a plurality of elements may be aligned in a three-dimensional array by dowels extending through the bores thereof, said elements likewise being capable of presenting clamping forces in a three-dimensional configuration whereby the device may readily and easily be used to clamp objects in either two or three dimensions.
Claim 3
Dependent Claim
32 words
A clamp means as in claim 1 wherein the element further includes bores on the inner face of the leg to accept accessory clamp means altering the inner surface of the legs.
