Abstract

Abstract At least two elongated structural elements are provided. They are of open-profiled cross-section, that is of T-shaped, U-shaped or similar cross-section, and have spaced opposite ends each of which has a flange extending transversely to the elongation of the respective element. Connecting means is provided at least on the axially outer sides of the respective flanges.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 191 words
In a toy erecting set, in combination, at least two elongated structural elements, at least one of said elements having a longitudinally extending first wall having parallel opposed planar major surfaces, said first wall being resiliently bendable transversely of its plane and provided with spaced ends; a pair of flanges extending from the respective ends of said wall to one side of the plane thereof and transversely to the elongation of said wall, each of said flanges having an axially outer side; said one element including an elongated second wall of stripshaped configuration having opposite end portions, and said second wall being arcuately curved within its general plane and relatively inflexible in its general plane compared to the flexibility of said first wall transversely of its general plane; detachably mating engaging means provided at said opposite end portIons and on the axially inner sides of said flanges so that, after said engaging means are mated, said first wall is resiliently held into general conformity with the curvature of said second wall; and mutually cooperating connecting means provided on said axially outer sides of said flanges and on another of said elements.
Claim 2
Dependent Claim 191 words
In a toy erecting set, in combination, at least two elongated structural elements, at least one of said elements having a longitudinally extending first wall having parallel opposed planar major surfaces, said first wall being resiliently bendable transversely of its plane and provided with spaced ends; a pair of flanges extending from the respective ends of said wall to one side of the plane thereof and transversely to the elongation of said wall, each of said flanges having an axially outer side; said one element including an elongated second wall of stripshaped configuration having opposite end portions, and said second wall being arcuately curved within its general plane and relatively inflexible in its general plane compared to the flexibility of said first wall transversely of its general plane; detachably mating engaging means provided at said opposite end portIons and on the axially inner sides of said flanges so that, after said engaging means are mated, said first wall is resiliently held into general conformity with the curvature of said second wall; and mutually cooperating connecting means provided on said axially outer sides of said flanges and on another of said elements.
Claim 3
Dependent Claim 25 words
In a toy erecting set as defined in claim 1, wherein at least said first wall of said one element is of synthetic plastic material.
Claim 4
Dependent Claim 21 words
In a toy erecting set as defined in claim 1, wherein at least said one element is of synthetic plastic material.
Claim 5
Dependent Claim 41 words
In a toy erecting set as defined in claim 1, said cooperating connecting means including an undercut groove in the axially outer side of one, and an undercut coupling head on the axially outer side of the other of said flanges.
Claim 6
Dependent Claim 38 words
In a toy erecting set as defined in claim 1, said mating engaging means being so configurated that, when it is in mated condition, the general plane of said first and second walls extend normal to one another.
Claim 7
Dependent Claim 25 words
In a toy erecting set as defined in claim 1, and further comprising coupling means including coupling apertures provided in said first and second walls.
Claim 8
Dependent Claim 103 words
In a toy erecting set as defined in claim 6, said coupling apertures each having a main portion bounded by a margin and each having a recess portion extending in said margin outwardly of said main portion; and said coupling means further comprising coupling elements each having a major body portion receivable in said main portion, and a projecting body portion extending laterally of said major body portion and extendable through said recess portion from one to the other side of the respective wall, for enabling locking of the respective coupling element by turning of the major body portion thereof about its axis.
Claim 9
Dependent Claim 153 words
In a toy erecting set, in combination, at least two elongated structural elements, at least one of said elements having a longitudinally extending first wall resiliently bendable transversely of its plane and provided with spaced ends; a pair of flanges extending from the respective ends of said first wall to one side of said plane; said one element including an elongated second wall of strip-shaped configuration having opposite end portions, and said second wall being arcuately curved within its general plane and relatively inflexible in its general plane compared to the flexibility of said first wall transversely of its general plane; detachably mating engaging means at said opposite end portions and on said flanges so that, after said engaging means are mated, said first wall is resiliently held into general conformity with the curvature of said second wall; and mutually cooperating connecting means provided on said flanges and on another of said elements.
Claim 10
Dependent Claim 153 words
In a toy erecting set, in combination, at least two elongated structural elements, at least one of said elements having a longitudinally extending first wall resiliently bendable transversely of its plane and provided with spaced ends; a pair of flanges extending from the respective ends of said first wall to one side of said plane; said one element including an elongated second wall of strip-shaped configuration having opposite end portions, and said second wall being arcuately curved within its general plane and relatively inflexible in its general plane compared to the flexibility of said first wall transversely of its general plane; detachably mating engaging means at said opposite end portions and on said flanges so that, after said engaging means are mated, said first wall is resiliently held into general conformity with the curvature of said second wall; and mutually cooperating connecting means provided on said flanges and on another of said elements.
