Detailed Description Referring to the drawings there is illustrated an elongate structural member 1 according to the invention. The structural member 1 is in this case for joining frame parts such as support beams 2 of a construction such as a wall or roof cladding system.
The structural member 1 comprises an elongate member, in this case in the form of a rolled tube 3 having an axially extending seam 4 and a continuous opening extending the length thereof defining opposite ends openings 6, 7. An entrapping member 10 is inserted into each end opening 6, 7 and a threaded insert is held captive in each entrapping member 10. In this case the threaded insert at the end opening 6 is provided by a nut 11 and the threaded insert at the end opening 7 is provided by a bolt 12.
The entrapping members 10 are injection moulded of a plastics material in a single part from the same tool. Each entrapping member 10 comprises a head part 15 which is external of the tube 3 and a shank 16 which is inserted into the tube 3. The head part 15 has a through hole 18. At a transition between the head 15 and the shank 16 a circumferentially extending groove 17 is formed to receive a swaged part 19 of the tube 3 on assembly as illustrated particularly in Fig. 3. The shank 16 of the entrapping member 10 defines an hexagonal-shaped recess for receiving a nut 11 or the head of a bolt 12. The hexagonal shape of the recess prevents relative rotation of the nut 11 or bolt 12, in use.
IE000148 The shank 16 of the entrapping member 10 has a slot 25 to accommodate the seam 4 of the tube 3. To retain the nut 11 or bolt 12 from pulling out of the entrapping member 10 the shank 16 also has a projection in the form of an annular ring 30 which extends radially inwardly. The ring 30 is sized and shaped to allow a nut 11 or bolt 12 to be push fitted into position while capturing the nut 11 or bolt 12 and preventing axial dislocation of the insert.
The shank 16 has three circumferentially spaced-apart slots 31 formed therein to define four shank elements 16(a) at an insertion end of the entrapping member 10 to facilitate insertion of the shank 16 into the elongate tube 3. Upon insertion of a threaded insert into the entrapping member 10 and upon insertion of the entrapping member 10 into a tube 3 the elements 16(a) flex slightly to engage the inside surface of the tube 3. To further engage and retain the entrapping member 10 in position in the tube 3 the shank 16 is formed with engagement projections in the form of small bumps 32 which extend radially outwardly to engage with the inner surface of the tube 3.
Locating means for aligning the entrapping member 10 with the tube 3 for assembly is in this case provided by a locating hole 35 in the head 15 of the entrapping member 10. The locating hole 35 is provided at a pre-set position relative to the slot 25 for aligning the slot 25 with the seam 4 of the tube 3 for assembly. This arrangement greatly facilitates automated assembly of the tube 3 with the entrapping members 10.
In use, the threaded inserts 11, 12 are first inserted into entrapping members 10.
This assembly may be readily automated. Once the inserts 11, 12 are in position they are held in place by the shape of the recess and the annular projections 30.
The appropriate entrapping member 10 and insert assembly is inserted into the rolled tube 3 and the tube 3 is swaged to deform into the groove 17 of the entrapping member 10. Depending on the desired application the elongate structural member 1 may be provided with a nut 11 at one end and a bolt 12 at 8 IE000148 the other end, as illustrated, or may be fitted with two bolts or two nuts. One typical arrangement is illustrated in Figs. 11 to 13. In this case a spacer 40 is also provided to conform with the shape of the engaged part of the support beam 2.
The invention provides an elongate structural member and entrapping member which are extremely efficient in use and are cost effective to produce because minimum parts are utilised and the assembly is readily automated.
Many variations on the specific embodiments of the invention described will be readily apparent and accordingly the invention is not limited to the embodiments hereinbefore described which may be varied in construction and detail.
