Abstract
Abstract A plurality of bar-shaped structural elements are provided in an assembly kit. A socket member serves for connecting at least two of these structural elements to one another and comprises first and second connecting means each of which is operative for releasably engaging an end portion of one of the structural elements and connecting the same to the socket member. At least one of the connecting means enables movement of the associated structural element relative to the socket member in a predetermined direction and plane.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
104 words
In an assembly kit, in combination, a plurality of bar-shaped structural elements; socket means, including first and second connecting means operative for releasably engaging respective end portions of at least two of said elements, at least one of said connecting means being a connecting element mounted for pivoting movement about a predetermined axis and being composed of at least two portions secured to one another with freedom of tilting movement about a given axis; building blocks provided with undercut coupling portions; and at least one complementary undercut coupling portion on said socket means for enabling releasable coupling of the latter to respective building blocks.
Claim 2
Dependent Claim
104 words
In an assembly kit, in combination, a plurality of bar-shaped structural elements; socket means, including first and second connecting means operative for releasably engaging respective end portions of at least two of said elements, at least one of said connecting means being a connecting element mounted for pivoting movement about a predetermined axis and being composed of at least two portions secured to one another with freedom of tilting movement about a given axis; building blocks provided with undercut coupling portions; and at least one complementary undercut coupling portion on said socket means for enabling releasable coupling of the latter to respective building blocks.
Claim 3
Dependent Claim
22 words
In an assembly kit as defined in claim 1, wherein said given axis and said predetermined axis cross one another in space.
Claim 4
Dependent Claim
93 words
In an assembly kit, in combination, a plurality of bar-shaped structural elements; socket means, including first and second connecting means operative for releasably engaging respective end portions of at least two of said elements, at least one of said connecting means enabling pivotal movement of the associated one of said elements with reference to said socket means in at least one predetermined plane; building blocks provided with undercut coupling portions; and at least one complementary undercut coupling portion on said socket means for enabling releasable coupling of the latter to respective building blocks.
Claim 5
Dependent Claim
93 words
In an assembly kit, in combination, a plurality of bar-shaped structural elements; socket means, including first and second connecting means operative for releasably engaging respective end portions of at least two of said elements, at least one of said connecting means enabling pivotal movement of the associated one of said elements with reference to said socket means in at least one predetermined plane; building blocks provided with undercut coupling portions; and at least one complementary undercut coupling portion on said socket means for enabling releasable coupling of the latter to respective building blocks.
Claim 6
Dependent Claim
33 words

Claim 7
Dependent Claim
43 words
In an assembly kit as defined in claim 4, said socket means having an exposed surface provided with two spaced-apart marginal portions, and each of said connecting means being provided on said socket means in the region of one of said marginal portions.
Claim 8
Dependent Claim
25 words
In an assembly kit as defined in claim 3; and further comprising at least one additional complementary undercut coupling portion provided on said socket means.
Claim 9
Dependent Claim
24 words
In an assembly kit as defined in claim 6, at least one of said undercut complementary coupling portions being elongated in said predetermined plane.
