DETAILED DESCRIPTION OF THE PREFERRED EM~ODIMENTS
Figure 1 shows a typical structure made rigid with joints
2 according to -the invention, structurel being composed of a pll1rality of hollow pipes 3.
~ igure 2 illustrates a typical joint 2, composed ~f a block member 4 to which is rigidly connected a pipe 3 of square cross-section. Pipe 3 is formed with four spaced apart pairs of parallel flanges 5 (which constitute the attachment means), one pair on each face, and each pair defining a longitudinal slot 6. The latter are adapted for the retention of suitable panels (not shown) to cover structure 1. Pipes are preferably further formed with an(3ular faces 7 for aesthetic appearance.
A joint 2 consists of a pair of block halves 8 which, when assembled, form the rectangular or cubic block 4. In Figure 2 the securing means consists of a long bolt 10 and nut 11. ~olt 10 extends through a face made in a central axis of each half 8.
At leas-t two faces of every block 4 are made with an opening 12. The latter is of rectangular shape in a plane normal to that of bolt 10 and of triangular shape in a plane longitudinal to that of`bolt 10 and such that the base of the triangle faces the bolt. Each opening 12 is equally divided between the two halves 8, each of the half-openings erected thereby having an inclined surface 12'extending away from its block face and towards the bolt 10.
A male member 13 has a front projection 14 corresponding exactly to an opening 12 in shape. Member 13, is in-tegrally formed of a plurality of frusto-conical sections 13' tapering towards projection 14. Member 13 is cross-sectionally square (see Fig. 3~.
Figures 2 and 3 advantageously show the female member of a joint 2, the former consisting of two cross-sectionally L-shlped segments 15 surrounding male member 13. Segmen-ts 15 are separate~ forming a cross-sectional square when disposed inside a pipe element 3. For assembly purpose an elastic band 16 keeps the two segments together at thelr mid lengths (see Figure 4). The inner surfaces of segments 15 are of exac-tly the same shape as male member 13, i.e. -they are formed with a plurality of frustro-conical indentations. The outer surface of segments 15 is formed with a plurality of spaced-apart raised transverse ribs 15' each having a frontward pointing ., . -apex.
Figure 2 depicts how a joint 2 holds a pipe 3. To secure a pipe 3 to a joint 2 the procedure is as follows: a female member 15 is placed inslde the end portion of a pipe 3 and a male member 13 is in turn placed inside female member 15.
In its initi,~l position male member 13 will have its rear end, designated at A, generally flush with the rear end o female member 15, designated at ~. Projection 14 will thus extend only slightly forward of pipe 3. The two block halves 8 are then assembled such that the edges of an opening 12 grip projection 140 Block halves 8 are made to bear against end 3' of pipe 3. Nut 11 is then tightened to draw projection 1~
in-to the fully locked position shown. Thus A will be moved a certain distance frontwardly relative to B of the female member, causing the latter to expand so that ribs 16 grip the inner surface of pipe 3.
Figure 5 depicts an alternate embodiment wherein an elongated bolt 17 extends axially of and through a modified . male member 13a the latter receiving a nut 18 and formed with-out Lhe front projection 140 Block halves 8 are iden-tical to those of Figure 2.
Figure 4 suggests how the embodiment shown in Figure ~
may be combined with the first embodiment descrlbed above to :~26~
Lorm a joint wherein Eive faces of blocks 4 are used to re-tain plpes 3.
Referring to Figure 6, there i5 shown means to attach a joint to a ceiling 19, although the joint could also be attached to a wall or floor. The means consists of a flat pla-te 20 secured in place by screws 21 and provided with a projection 22 rigidly at-tached to its outer surface. Projectlon ~2 is identical to a projection 14 of a male member 13, beiny meant for engagement in openings 12 of a block 4~ ~igure 1 shows plates 20 attached to a floor.
Figures 7 and 8 illustrate another feature of the inven-tion, namely a pivotal connection for a pipe 3. The connection comprises: a pair of parallel spaced-apart sector plates 23 integrally joined at one end. The same end has a projection 2 integrally formed therewith. Extending hetween sector plates 23 is a large pivotal member 25 which has a rear portion 25' transversely as wide as sector plates 23 (see Figure 8~. Por-tion 25' is formed with a rectangular cavity 26 and a trans-verse slot 27.
Pivotal member 25 has converging sides at the above-mentioned one end, merging together thereat in a rounded con-figuration 25''. Adjacent the same end is a transverse pivot rod 28 extendlng through both member 25 and sector plates 23.
Thus member 25 can pivot as shown by the arrows in Figure 7.
Cavity 26 and slot 27 serve to position the long bolt 17 shown in Figure 5 and a washer 29 so that bolt 17 may ex-tend through a male member 13a and be secured by a nut as described above. Such a feature may be utilized for one of the angular pipe connections indicated at 30 in Figure 1.
