Abstract
Abstract A fabricating component has several first holes, and a second hole orthogonal to and between the first holes. One end of the first hole has an enlarged indentation, and the other end of the hole has a projection shaped like the indentation so that the projections of one component can be interlocked with the indentations of another component. Several fabricating components can be connected by components which have the shape of a rod, a tube, a U-shaped member, or an elongated grooved member having a series of projections.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
135 words
A fabricating device comprising, in combination: a fabricating component including at least two substantially parallel major surfaces and including at least one first perforation having its longitudinal axis disposed substantially transverse to said major surfaces; said fabricating component including at least one second perforation having its longitudinal axis disposed substantially parallel to said major surfaces; one of said major surfaces having a projection which surrounds one end of said first perforation; the other one of said major surfaces having an indentation which surrounds the other end of said first perforation; the cross section of said projection being substantially similar to the cross section of said indentation; and a connecting component which is adapted to interconnect at least two of said fabricating components by fitting at least partially within said first perforation or said second perforation.
Claim 2
Dependent Claim
135 words
A fabricating device comprising, in combination: a fabricating component including at least two substantially parallel major surfaces and including at least one first perforation having its longitudinal axis disposed substantially transverse to said major surfaces; said fabricating component including at least one second perforation having its longitudinal axis disposed substantially parallel to said major surfaces; one of said major surfaces having a projection which surrounds one end of said first perforation; the other one of said major surfaces having an indentation which surrounds the other end of said first perforation; the cross section of said projection being substantially similar to the cross section of said indentation; and a connecting component which is adapted to interconnect at least two of said fabricating components by fitting at least partially within said first perforation or said second perforation.
Claim 3
Dependent Claim
59 words
A device characterized in accordance with claim 1, wherein said fabricating component includes one or more grooves which are diaposed between said major surfaces and which are shaped similar to the outer periphery of said major surfaces, and said axis of each second perforation being disposed intermediate between and orthogonal to the axis of at least two first perforations.
Claim 4
Dependent Claim
32 words
A device characterized in accordance with claim 1, wherein said fabricating component includes a plurality of said first perforations which are spaced apart at uniform intervals and arranged within a straight line.
Claim 5
Dependent Claim
64 words
A device characterized in accordance with claim 1, wherein said fabricating component includes a plurality of said first perforations which are spaced apart at uniform intervals and arranged in a first straight line, and includes a plurality of said first perforations which are spaced apart at uniform intervals and are arranged in a second straight line which is parallel to said first straight line.
Claim 6
Dependent Claim
54 words
A device characterized in accordance with claim 1, wherein said connecting component includes a base portion and a plurality of projections affixed to said base portion at uniform intervals, and wherein said projections affixed to said base portion are adapted to fit within said second perforations of at least two of said fabricating components.
Claim 7
Dependent Claim
61 words
A device characterized in accordance with claim 5, wherein said connecting component has a groove which is disposed along or parallel to the longitudinal axis of said connecting component, and said groove of said connecting component is disposed along the surface of said base portion which is opposed to the surface of said base portion to which said projections are affixed.
Claim 8
Dependent Claim
55 words
A device characterized in accordance with claim 1, wherein said connecting component is U-shaped and has legs which are spaced apart by an interval which corresponds to the interval between said second perforation of a first fabricating component and said second perforation of a second fabricating component which is contiguous to said first fabricating component.
Claim 9
Dependent Claim
44 words
A device characterized in accordance with claim 1, wherein said connecting component has a tubular shape with an aperture which extends parallel to the entire length of the longitudinal axis of said connecting component, and said connecting component has a discontinuous annular cross section.
Claim 10
Dependent Claim
28 words
A device characterized in accordance with claim 8, wherein the external diameter of said tubular shape is larger than the internal diameter of said first or second perforation.
Claim 11
Dependent Claim
51 words
A device characterized in accordance with claim 1, wherein said connecting component is made of flexible material and has a rodlike shape with a groove which opens onto the external periphery of said connecting component and which is directed to and formed along the entire longitudinal axis of said connecting component.
