Abstract
Abstract This invention concerns a set of assembly elements consisting of assembly rails fitted to engage each other along a nodal line, and which may be intended for the assembly of sheet elements; the individual rail may be attached along the edge of each sheet element by its underside by generally known means, such as screws, glue or tongued and grooved joints; the cross-section of the individual assembly rail consisting of a basic part and a hook-shaped part; at least the basic parts, duly assembled, will bear against each other, preferably along radial surfaces.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
150 words
A set of at least three elongated assembly rails for engaging each other along an axial line, at least one of said rails being adapted to have a plate affixed thereto, each of said rails having at least one axially extending end portion comprising a base part and a resilient hook-shaped part, the base part of each adjacent rail having a pair of radially directed surfaces adapted to mate with the corresponding radially directed surfaces of the base parts of the adjacent rails, and the other hook-shaped parts thereof all being substantially equal in size and forming a cylindrical hole around said axial line and a locking member disposed in said hole for urging the portions of said hook-shaped parts adjacent said hole against each other, said locking member exerting a camming action which thereby forces said radially directed surfaces together, whereby said rails are stabilized in a locking relationship.
Claim 2
Dependent Claim
150 words
A set of at least three elongated assembly rails for engaging each other along an axial line, at least one of said rails being adapted to have a plate affixed thereto, each of said rails having at least one axially extending end portion comprising a base part and a resilient hook-shaped part, the base part of each adjacent rail having a pair of radially directed surfaces adapted to mate with the corresponding radially directed surfaces of the base parts of the adjacent rails, and the other hook-shaped parts thereof all being substantially equal in size and forming a cylindrical hole around said axial line and a locking member disposed in said hole for urging the portions of said hook-shaped parts adjacent said hole against each other, said locking member exerting a camming action which thereby forces said radially directed surfaces together, whereby said rails are stabilized in a locking relationship.
Claim 3
Dependent Claim
32 words
The set according to claim 1, comprising four of said rails, the hook-shaped part of each said rail subtending an angle on the order of 90° as measured from said axial line.
Claim 4
Dependent Claim
14 words
The set according to claim 1 wherein said locking member is circular in cross-section.
Claim 5
Dependent Claim
12 words
The set according to claim 3, wherein said locking member is cylindrical.
Claim 6
Dependent Claim
13 words
The set according to claim 3, wherein said locking member is slightly conical.
Claim 7
Dependent Claim
21 words
The set according to claim 1, wherein said locking member comprises a single elongated plug extending the length of said hole.
Claim 8
Dependent Claim
34 words
The set according to claim 1, wherein said locking member comprises a pair of plugs, each said plug being relatively short with respect to said cylindrical hole and being inserted at one end thereof.
Claim 9
Dependent Claim
28 words
The set according to claim 7, wherein each plug further comprises a square end plate of a size sufficient to cover the total cross-sectional area of said rails.
Claim 10
Dependent Claim
80 words
The set according to claim 1, wherein the contact faces of said base parts bearing against each other run diagonally with respect to said rails and extend radially from said axial line, each hook-shaped part comprising a base portion having an essentially linear inner face, an axially extending shoulder, an outer portion having an arcuate inner face, and an axially extending outer face, whereby said outer face of each hook-shaped part mates with said shoulder of each adjacent hook-shaped part.
Claim 11
Dependent Claim
20 words
The set according to claim 1 wherein said locking member is adapted to be expandible while disposed in said hole.
Claim 12
Dependent Claim
18 words
The set according to claim 1, wherein said locking member is integrally formed with one of said rails.
