Claim 4

An element adapted for connection to components of a diagram board assembly comprising: a rectangular body including opposite sidewalls, at least two opposing sidewalls each including at least one pair of depending transversely spaced legs, each leg having an inner face and an outer face and opposite side faces, each said outer face including a curved portion; said legs of each pair being substantially in-line so that said all side faces thereof are intersected by an imaginary straight line substantially parallel to said cooperating sidewall; the curved portion of the outer face of one leg of a pair being concave while the curved portion of the outer face of the other leg being convex; and said legs being made of elastic material and each pair of legs are mounted to said body so that said legs are flexible in a first direction, which is in a plane perpendicular to the sidewall, and are flexible in a second direction which is in a longitudinal plane including each said pair of legs and imaginary straight line to enable engagement with another component of said assembly.

Claim 5

A connecting element as defined in claim 1 or claim 2, wherein the curvature of the concavity of the outer face of one leg of a pair differs slightly from the curvature of the convexity of the outer face of the other leg of said pair so as to provide line contacts between engaging faces of two adjacently connected elements having similar leg construction.

Claim 6

A connecting element as defined in claim 1 or claim 2, wherein each said inner face include a curved portion; the curved portion of the inner face of one leg of a pair being concave while the inner face of the other leg of said pair is convex.

Claim 7

A connecting element as defined in claim 1 or claim 2, wherein the legs taper on all sides to the lower edge thereof.

Claim 8

An element adapted for connection to components of a diagram board comprising: a body having a plurality of sidewalls; at least one pair of depending transversally spaced legs projecting beyond one sidewall of said body and being integral therewith, said legs being of elastic material; each leg having an inner face, an outer face, and first and second side faces; said legs first side faces being adjacent each other and substantially in-line along the length of said sidewalls, and said legs second side faces being substantially in-line with said first side faces of both legs, and each other; said leg first side faces extending from said sidewall at an angle so that imaginary extensions of said leg first side faces intersect, and imaginary extensions of said legs' second side faces intersect each other; the outer face of each leg including a curved portion; and the curved portion of the outer face of one leg of a pair being concave while the curved portion of the outer face of the other leg of the pair is convex.

Claim 9

An element adapted for connection to components of a diagram board comprising: a body having a plurality of sidewalls; at least one pair of depending transversally spaced legs projecting beyond one sidewall of said body and being integral therewith, said legs being of elastic material; each leg having an inner face, an outer face, and first and second side faces; said legs first side faces being adjacent each other and substantially in-line along the length of said sidewalls, and said legs second side faces being substantially in-line with said first side faces of both legs, and each other; said leg first side faces extending from said sidewall at an angle so that imaginary extensions of said leg first side faces intersect, and imaginary extensions of said legs' second side faces intersect each other; the outer face of each leg including a curved portion; and the curved portion of the outer face of one leg of a pair being concave while the curved portion of the outer face of the other leg of the pair is convex.

Claim 10

A connecting element as defined in claim 6, wherein the curvature of the concavity of the outer face of one leg of a pair differs slightly from the curvature of the convexity of the outer face of the other leg of said pair so as to provide line contacts between engaging faces of two adjacently connected elements having similar leg construction.

Claim 11

Claim 12

A connecting element as defined in claim 6 wherein each leg includes a lower edge thereof, and wherein the intersection of each leg second side face and lower edge is curved to facilitate insertion of said legs into a cavity of a component with which said connecting element cooperate.
