Abstract
Abstract This invention relates to a tie member which enables an angle joint to be produced between two obliquely cut hollow members, and consists of two non-deformable parts each of which has two arms adapted to fit into one or other of the hollow members to be joined, and means for moving one part relative to the other to enable them to be moved apart. One of the parts includes two retractable plungers which slide in openings in its arms and which are each subject to thrust from a spring which causes them to project towards the facing wall of one of the hollow members so that they will enter a bore formed in this wall. The arms of the two parts are resiliently connected together, in particular by the springs to prevent the parts from becoming detached from one another. The tie member according to the invention enables a joint to be made under conditions of remarkable ease and simplicity, and automatically ensures that the hollow members are properly clamped against one another.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
267 words
A tie member for forming an angled joint between two obliquely cut hollow members, said member comprising two non-deformable oppositely-faced parts each having two arms whose shape and included angle are suitable to enable them to fit into either of the hollow members to be joined, the arms of one part coming into place adjacent those walls of the hollow members which are situated on the inside of the angle and the arms of the other part coming into place adjacent the opposing walls situated on the outside of the angle, and the corners of the two parts being situated near the plane of junction of the two hollow members, said tie member also having means for moving one part relative to the other which are so arranged as to enable the parts to be moved apart by a pressure exerted where their corners are situated, and wherein one of said parts contains two retractable plungers, one of which is carried by one arm and is arranged to slide substantially perpendicularly thereto in an opening formed in said arm, and the other of which is carried by the other said arm and slides in a similar fashion, spring members arranged to cause each said plunger to project from the appropriate arm towards the adjacent wall of one of the hollow members so that said plunger can enter and latch in a bore formed in said wall, and wherein means are arranged between the facing arms of said two parts to form a resilient connection between said two parts and prevent them from becoming detached from one another.
Claim 2
Dependent Claim
267 words
A tie member for forming an angled joint between two obliquely cut hollow members, said member comprising two non-deformable oppositely-faced parts each having two arms whose shape and included angle are suitable to enable them to fit into either of the hollow members to be joined, the arms of one part coming into place adjacent those walls of the hollow members which are situated on the inside of the angle and the arms of the other part coming into place adjacent the opposing walls situated on the outside of the angle, and the corners of the two parts being situated near the plane of junction of the two hollow members, said tie member also having means for moving one part relative to the other which are so arranged as to enable the parts to be moved apart by a pressure exerted where their corners are situated, and wherein one of said parts contains two retractable plungers, one of which is carried by one arm and is arranged to slide substantially perpendicularly thereto in an opening formed in said arm, and the other of which is carried by the other said arm and slides in a similar fashion, spring members arranged to cause each said plunger to project from the appropriate arm towards the adjacent wall of one of the hollow members so that said plunger can enter and latch in a bore formed in said wall, and wherein means are arranged between the facing arms of said two parts to form a resilient connection between said two parts and prevent them from becoming detached from one another.
Claim 3
Dependent Claim
68 words
A tie member according to claim 1, wherein each said plunger has shoulder which defines an end section of smaller diameter which is adapted to enter and latch in the bore in one of the hollow members, the other portion of said plunger being of larger diameter than said bore so that said plunger will lock in the hollow member at the point where its shoulder is situated.
Claim 4
Dependent Claim
39 words
A tie member according to claim 1, wherein each said plunger has an abutment collar, which is arranged in the vicinity of its end nearer the other said part, to restrict its travel under the prompting of said spring.
Claim 5
Dependent Claim
56 words
A tie member according to claim 1, wherein said two arms of one of said parts each have at their free end a return which is adapted to act as an end-of-travel abutment for the end of the facing arm of the other said part, to restrict the degree to which said parts can move apart.
Claim 6
Dependent Claim
44 words
A tie member according to claim 1, wherein said part which is not provided with the plungers has, on each of its arms, a bulge which is adapted to press against the inner face of the appropriate wall of one of the hollow sections.
Claim 7
Dependent Claim
30 words
A tie member according to claim 1, wherein said plungers are carried by the said part which is adapted to take up a position on the outside of the angle.
Claim 8
Dependent Claim
116 words
A tie member according to claim 1, wherein said means for moving one said part relative to the other said part consist of a pressure screw which is screwed into a tapped hole formed in the said part which is adapted to take up a position on the outside of the angle, said screw being arranged on the line bisecting the angle formed by the two arms of the said part, and wherein the other said part has, at the point where its corner is situated, a bearing situated facing said pressure screw which has a face orthogonal to the junction plane against which the end of said pressure screw is intended to come to bear.
Claim 9
Dependent Claim
61 words
A tie member according to claim 1, wherein said means forming the resilient connection between the arms of the two parts comprise said spring members and said retractable plungers, said spring members being arranged between the arms of said parts at the points where said plungers are situated so as to thrust against the latter and to connect the parts resiliently.
Claim 10
Dependent Claim
57 words
A tie member according to claim 8 wherein each of said spring members comprises a spring of conical shape whose end of smaller diameter is inserted in a recess formed in the end of its said plunger and whose other, larger diameter end is engaged in a groove provided in the facing arm of said other part.
