Connection element structure for a non-textile fabric
View Patent ↗Non-textile fabric panels (FIG. 17 ) are either formed, formed and joined, or joined by using plates or elements 1, 2, 51, 52 having edges with connection structures of complementary shaped and spaced knuckles 54, 55, 58 that interfit with one another. The knuckles include surfaces 57, 56, 59 , that interfit and engage similar structures on adjacent elements or plates. Aligned, interfitting connection structures or knuckles can hinge along major bending axes, giving the non-textile fabric made thereby the ability to flex and bend like textile fabric or leather. Buttressing surfaces 7, 57 between connected knuckles help prevent early disengagement of intermitting surfaces when the non-textile fabric is subjected to strong tensile forces. Elements 51, 52 having the overall shape of a right isoscoles triangle in the plane of the non-textile fabric formed therefrom thus provide four major bending axes for superior flexible strength. Knuckles 22, 24 on the free edges of non-textile fabric panels made according the invention can be interleaved in a post manufacturing operation to make strong and almost invisible seams between panels.
1. A non-textile fabric comprising:
a. at least a first element having at least three sides, each side defining a first connection structure having an axis of rotation, which axes intersect in the form of a right triangle;
b. at least a second element having at least three sides, each of said sides defining a second connection structure having an axis of rotation, which axes intersect in the form of a right triangle; and
c. wherein said at least first and at least second elements are attached together using said connection structures, and in turn are attached together with similarly attached first and second elements using said connection structures to form out of at least some intersecting axes of rotation the general shape of a parallelogram in a repeating manner to form the non-textile fabric having at least three major bending axes, said first and second connection structures, when connected together, form a hinge along the connected sides of the first and second elements, the hinge having a solid structure with substantially no gaps or spaces.
2. A non-textile fabric as defined in claim 1 , wherein:
a. said connection structure on said first element comprises at least one knuckle defining at least one pintle; and
b. said connection structure on said second element includes at least one recess sized for receiving said at least one pintle, whereby a hinge connection is formed between the connection structures of the first and second elements.
3. A non-textile fabric as defined in claim 2 , wherein said recess is conical and said pintle is conical.
4. A non-textile fabric as defined in claim 2 , wherein said recess and said pintle are formed so the first element and the second element can rotate about one of said major bending axes with respect to each other when in engagement.
5. A non-textile fabric as set forth in claim 1 wherein said right triangle is a right isosceles triangle.
6. A non-textile fabric as set forth in claim 1 wherein said parallelogram is a square.
7. A non-textile fabric comprising:
a. at least a first element having a side defining a connection structure having an axis of rotation;
b. at least a second element having at least a side defining a connection structure having an axis of rotation; and
c. wherein said at least first and at least second elements are attached together using said connection structures, said connection structure on said first element includes at least one knuckle defining at least one recess; and said connection structure on said second element includes at least one knuckle defining at least one pintle shaped to be received in the at least one recess for rotation therein, whereby a hinge connection is formed by the connection structures of the first and second elements, the hinge connection being a substantially solid structure with at most minimal gaps along connected sides of said first and second elements such that the knuckles are kept from flexing with respect to one another to help prevent the pintle from pulling from the recess.
8. The non-textile fabric as set forth in claim 7 wherein said first element has at least three sides, each side defining a connection structure having an axis of rotation, which axes intersect in the form of a right triangle.
9. The non-textile fabric as set forth in claim 8 wherein said second element has at least three sides, each side defining a connection structure having an axis of rotation, which axes intersect in the form of a right triangle.
10. The non-textile fabric as set forth in claim 7 wherein the connection structure of said first element comprises a pair of knuckles.
11. The non-textile fabric as set forth in claim 10 wherein each of said pair of knuckles defines a single recess, whereby the hinge connection has two of the recesses.
12. The non-textile fabric as set forth in claim 11 wherein each recess of the pair of knuckles open inwardly towards one another.
13. The non-textile fabric as set forth in claim 7 wherein the connection structure of the second element comprises a single knuckle.
14. The non-textile fabric as set forth in claim 13 wherein the single knuckle has two pintles, whereby the hinge connection has two pintles.
