Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
53 words
A module consisting of: a base portion; a pair of spaced flanges depending from said base portion, each of said flanges having a free end, said flanges having facing surfaces defining an arcuate surface therebetween; and at least one channel extending continuously along said arcuate surface between said free ends of said flanges.
Claim 2
Dependent Claim
53 words
A module consisting of: a base portion; a pair of spaced flanges depending from said base portion, each of said flanges having a free end, said flanges having facing surfaces defining an arcuate surface therebetween; and at least one channel extending continuously along said arcuate surface between said free ends of said flanges.
Claim 3
Dependent Claim
30 words
The combination including the module of claim 1 and a rigid planar element of finite thickness whereby said rigid planar element may be slidably received in one of said channels.
Claim 4
Dependent Claim
24 words
The combination described in claim 2 wherein said rigid planar element has an edge portion substantially conforming to the configuration of said arcuate surface.
Claim 5
Dependent Claim
50 words
The module of claim 1 having at least one detent provided in the surface thereof whereby said module can be joined to a second module provided with at least one detent, by means of a pin received in a detent in said module and a detent in said second module.
Claim 6
Dependent Claim
67 words
A module consisting of: a first planar surface; a pair of parallel planar surfaces extending at right angles from said first planar surface; an arcuate recessed surface located between said parallel planar surfaces; a plurality of parallelly spaced channels extending continuously along said arcuate surface; means for gripping said modules whereby they may be manually moved; and means for maintaining said module in contact with additional modules.
Claim 7
Dependent Claim
67 words
A module consisting of: a first planar surface; a pair of parallel planar surfaces extending at right angles from said first planar surface; an arcuate recessed surface located between said parallel planar surfaces; a plurality of parallelly spaced channels extending continuously along said arcuate surface; means for gripping said modules whereby they may be manually moved; and means for maintaining said module in contact with additional modules.
