Abstract
Abstract The invention relates to a spacial joint for parts, which will find application in the lighting, building and trade industries. The present invention provides a spacial joint for quick and precise joining of parts with no possibility of turning them, which will ensure stability of the spacial disposition of the parts. The joint includes two shells with clamping beds and a mating edge formed therein, the shells being fixed one to the other through joining elements. Each shell has at least two annularly disposed beds, and on the mating edge of each bed is formed a bevelled edge, an engaging projection, and an inclined opening through which a joining element such as a bolt may pass.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
122 words
A spacial joint for joining two or more parts comprising two mating shells, each shell having at least two spacially angularly disposed members, said members providing a clamping surface for engagement with a surface of the parts to be joined, each shell being provided with a common mating edge between said members and on which there is formed a beveled edge portion and an engaging projection and an inclined opening through which a joining element may pass so as to join the two shells in mating relationship thereby engaging the projection of one shell with the beveled edge portion of the other shell and providing joining pressure on said clamping surface with respect to the surface of the parts to be joined.
Claim 2
Dependent Claim
122 words
A spacial joint for joining two or more parts comprising two mating shells, each shell having at least two spacially angularly disposed members, said members providing a clamping surface for engagement with a surface of the parts to be joined, each shell being provided with a common mating edge between said members and on which there is formed a beveled edge portion and an engaging projection and an inclined opening through which a joining element may pass so as to join the two shells in mating relationship thereby engaging the projection of one shell with the beveled edge portion of the other shell and providing joining pressure on said clamping surface with respect to the surface of the parts to be joined.
Claim 3
Dependent Claim
27 words
A spacial joint, as claimed in claim 1, wherein said members are formed with said clamping surface complementary to the surface of the parts to be joined.
Claim 4
Dependent Claim
21 words
A spacial joint, as claimed in claim 1, wherein said engaging projection is formed as an integral part of said shell.
Claim 5
Dependent Claim
29 words
A spacial joint, as claimed in claim 1, wherein said engaging projection is formed as an additional sectional element, immovably fixed on the common mating edge of the shell.
Claim 6
Dependent Claim
33 words
A spacial joint, as claimed in claim 1, wherein the engaging projection is formed as a ball, movably placed on bearings in a socket made in the common mating edge of the shell.
Claim 7
Dependent Claim
34 words
A spacial joint, as claimed in claim 1, wherein the said common mating edge of the shell with the bevelled edge, the engaging projection and the inclined opening is formed as an independent element.
