  • the internal threaded part of the plug may be integrally formed in the plug but is preferably provided by a metal
  • both ends of the first member will be provided with plugs as described above and there will be as plurality of keyhole apertures in the second member. These may be disposed along the length of the second 30 member and also at differing radial orientations.
  • first and second membes are not necessarily straight, but could be curved or include bends. Both the first and second members may be formed with external grooves or channels for receiving panels.

  • the tube 12 has a wall 14 in which is formed a groove 16.
  • the groove 16 defines a shoulder 18, the purpose of which will be explained hereinafter.
  • a plug 28 ( Figure 2) has a head portion 29 and a main portion 30.
  • Four axial slots 32 in the end of the main portion 30 define four legs 34, upstanding from each of which is a detent 36.
  • the main portion 30 is of such a size that it may be pushed into the end of the tube 12 with the legs 34 under resilient compression.
  • the head portion 29 abuts the end of the tube 12
  • the detents 36 will enter the groove 16 and the compression on the legs 34 will be released.
  • the action of the detents 36 against the shoulder 18 will then prevent removal of the plug 28 from the tube 12.
  • the plug 28 is provided with an internally threaded bore 38.
  • a bolt 20 comprises a head 22, a threaded shaft 26 and a neck portion 24 intermediate the head 22 and shaft 26 and of smaller diameter than either of them.
  • a second member 40 ( Figure 4) of a coupling according to the invention comprises a tube 42 of circular cross- -section.
  • the wall 44 of the tube 42 is provided with keyhole apertures 50 (two shown), each of which comprises a hole 52 intersected by a slot 54.
  • the hole 52 is of a size such that the head 22 of the bolt 20 can pass through it.
  • the slot 54 is of a lesser width, whereby it may accommodate the neck portion 24 of the bolt 20, but not allow the head 22 or the threaded shaft 26 of the bolt 20 to pass through it.
  • Figures 5 and 6 show a locking washer 60.
  • the locking washer 60 has a central hole 62 through which the threaded shaft 26 of the bolt 20 can pass. Face 64 of the locking washer 60 is shaped for abutment to the outer surface of the wall 44 of the tube 42, while face 66 of the locking washer 60 is shaped for abutment to the free end of the head portion 29 of the plug 28. Upstanding from the face 64 of the locking washer 60 is a pin 68 sized such that it may be inserted in the hole 52 but not the slot 54 of the keyhole aperture 50.
  • the coupling of the invention is assembled as follows.
  • the head 22 of the bolt 20 is passed through the hole 52 of the keyhole aperture 50.
  • the neck portion 24 of the bolt 20 is then slid into the slot 54 of the keyhole aperture 20, leaving the head 22 within the tube 42 and the threaded shaft 26 projecting radially from the tube 42.
  • the locking washer 60 is presented to this assemblage in such a way that the threaded shaft 26 passes through the central hole of the locking washer 60, the pin 68 enters the hole 52 of the keyhole aperture 50 and the face 64 of the locking washer 60 abuts the wall 44 of the tube 42.
  • the threaded shaft 26 is then screwed into the threaded bore 38 of the plug 28 until the face 66 of the locking washer 60 abuts the end of the head portion 29 of the plug 28.
  • the plug 28 may be engaged in the end of the tube 12 as above described either before or after the last described operation.
  • FIGs 7 and 8 of the drawings there are shown an alternative tubular second member and an alternative plug.
  • the same reference numerals are used for the parts which correspond to those of the tubular second member shown in Figure 4 and the plug shown in Figure 2.
  • a rebate 70 is formed in the tubular second member around the slot 54, and the head portion 29 of the plug is differently shaped, including a projection 72.
  • the tubular second member and plug of Figures 7 and 8 are used together with the tubular first member and bolt of Figures 1 and 3 (but omitting the locking washer of Figures 5 and 6) to form an alternative coupling according to the invention.
  • the method of assembly comprises fitting the bolt 20 to the tubular second member as previously described and then screwing the plug 28 on to the threaded shaft 26 of the bolt 20 so that the projection 72 engages in the recess 70, preventing lateral movement of the bolt 20.
  • the plug 28 can be engaged with the end of the tube 12 before it is screwed on to the threaded shaft 26 or afterards.
  • the coupling of the invention is of particular use in joining struts and ties into useful structures. Examples are shown in Figures 9 and 10.

Abstract

Un accouplement pour deux éléments tubulaires (10, 40), dont un (40) est pourvu d'une ouverture en forme de trou de serrure (5) avec un trou (52) entrecoupé d'une fente (54) et l'autre (10) est pourvu d'un obturateur (28) possédant un perçage taraudé (38), est réalisé à l'aide d'un boulon (20) dans lequel une tête (22) est séparée d'une tige filetée extérieurement (26) par un collet (24). La tête (22) et la tige (26) sont dimensionnées de manière à ne pas pouvoir passer à travers la fente (54), mais le collet (24) est d'une largeur inférieure et peut passer à travers la fente (54). La tête (22) est passée à travers le trou (52) et le collet (24) est glissé dans la fente (54). Le perçage taraudé (38) de l'obturateur (28) est ensuite vissé sur la tige (26). Des moyens sont prévus pour bloquer en position le boulon (20), et comportent de préférence une rondelle (60) pourvue d'un trou (62) à travers lequel la tige (26) peut dépasser et d'un ergot (68) s'engageant dans le trou (52).
