Abstract

A tube or rod joining device consisting of a tubular body (1), a tensile element (2), and a worm screw (3), which together assemble a butted tube (4) at a pre-determined angle to a through tube (5). The tensile element (2) is looped around the through tube (5) and tensioned by the worm screw (3) and retained at the other end by a ridge on the tensile element acting against the tubular body (1) thus fixing the assembly. Variations in through tube (5) diameter are accommodated by differing strap lengths.

Description

Invention Title: Tube Joining Device
Technical Field
The present invention relates to tube or rod assembling devices particularly for the joining of a first tube or rod to abut a second tube or rod in a tee arrangement.
Background Art
The present invention provides an alternative to a prior art method of clamping tubes together by bolting two clamp halves, which are specifically formed to nest the particular tubes used in the joint. This method is costly in terms of the variety of clamps needed to cater for every possible joint combination and the associated high stock holding requirements.
It is the object of the present invention to overcome the above disadvantage by providing an assembly fitted to a first tube or rod end which incorporates a tensile element or strapping that can encompass any reasonable diameter of a second tube or rod that is to be joined, simply by changing the length ofthe tensile element.
Disclosure of Invention
There is disclosed herein a fitting assembly to join two tubes or rods, as defined herein, said assembly comprising a tubular body having a bore adapted to be sleeved upon an end portion of a first tube or rod, a pliable tensile element, as defined herein, having a first end fixed to said body and extending in a loop from one end ofthe body to encompass a second tube or rod to be held to the first tube or rod, and tensioning means mounted to said tubular body engaging the other end of said tensile element to reduce the size of said loop. Description of drawings
Fig 1. is a schematic perspective view of the fitting assembly showing a butted pipe joined to a thru pipe.
Fig 2 is a schematic sectioned end elevation through the butted pipe and fitting assemble.
Fig 3. is a schematic perspective view of the fitting assemble showing a cut away section.
Best mode for carrying out invention.
A preferred form of the present invention will now be described by way of example with reference to the accompanying drawings.
As shown in the drawings the fitting assembly of the preferred embodiment is made up of a tubular body 1, a tensile element 2 defined here as a pliable strap (as shown) or cable or pliable wire, and a tensioning means in the form of a worm screw 3. The purpose of the fitting is to join tubes or rods 4 and 5, defined here as elongated structures including pipes(as shown) or tubes or rods of circular or non circular section.
The tubular body 1 is sleeved onto the end of pipe 4. The strap 2 passes through and is contained by a passage formed by a cavity between the tubular body 1 and the pipe 4. The end of the strap 2 is retained by a retention device 6 at one end of the strap which acts against the end edge of tubular body 1. The strap 2 forms a loop and is retumed to the tubular body 1 where it is engaged by a tensioning device in the form of a worm screw 3. The worm screw 3 engages thread indentations on the strap 2 so that when the screw is rotated it produces relative movement ofthe strap which pulls up and hence reduces the loop thus tightening the pipe 5 to the tubular body 1. The screw 3 is supported by its shoulder acting on the end ofthe tubular body 1. The retention ofthe strap 2 to one end ofthe tubular body 1 is achieved by a retention device 6 consisting of a ridge formed on strap 2, reinforced by the strap being folded back and fastened to itself at 7. The ridge formation at 6 acts against the tubular body 1. The action of the screw 3 also has the effect of forcing the additional material created near 6 by the folded back portion of strap 2, between the pipe 4 and the tubular body 1. This folded back flap thus wedges the body 1 to the pipe 4.
The tubular body 1 can be constructed with extruded or moulded, metal or plastic, the strap 2 can be constructed from metal or plastic, sheet or wire, and the screw 3 from metal.
The fitting described above can be utilised in many different combinations to provide a variety of assembled configurations such as interlocking the straps of two fitting assemblies forming a variable angle corner arrangement. Variations in pipe 5 diameter can be accommodated merely by fitting a strap 2 of suitable length.
In one form the end of the tubular body engages the thru pipe 5 with a countered surface 8 in a seamless manner so as to set the radial location ofthe tubular body with respect to the through pipe 5.
In another form the tubular body 2 end is not contoured to the shape of the thru pipe 5, but has a straight edge which abuts in tangent with the circumferential exterior of thru pipe 5.
Another form of the invention is a tubular body as above provided with slots at one end, through which a banded pipe clamp device of known and prior art is fed, again looping the thru pipe and in the action of tensioning, via its own thread engaging mechanism, clamping the tubular body so that it firmly abuts the thru pipe thus locating and holding the attached butted tube or rod.

Claims

Claims
The claims defining the invention are as follows:
1) A fitting assembly to join two tubes or rods, said assembly comprising a tubular body having a bore adapted to be sleeved upon an end portion of a first tube or rod, a pliable tensile element, having a first end fixed to said body and extending in a loop from one end of the body to encompass a second tube or rod to be held to the first tube or rod, and tensioning means mounted to said tubular body engaging and acting on the other end of said tensile element to reduce the size of said loop.
2) A fitting assembly as claimed in claim 1 in which the said tensile element in the form of a strap has a ridge formed at one end for retention purposes which is reinforced by the said strap folding back on itself and being fastened to itself.
3) A fitting assembly as claimed in any of claim 1 to 2 in which the said strap increases in thickness due to said folded back end or other means and this said end being forced or wedged between the said tubular body and first tube.
4) A fitting assembly as claimed in any of claim 1 to 3 in which said pliable tensile element can be engaged by threaded means to induce tension in said element along a line substantially parallel with the major axis of said first tube.
5) A fitting assembly as claimed in any of claim 1 to 4 in which said pliable tensile element can be changed in length independently from said body to accommodate variation in said second tube diameter.
6) A fitting assembly as claimed in any one of claim 1 to 5 wherein the said tubular body has a contoured surface complementary to the said second tube so as to sealingly connect the said body to the said second tube.
7) A fitting assemble as claimed in any of claim 1 to 6 in which tubes or rods are of either circular or non circular cross section.
8) An assembly to connect two tubes or rods substantially as hereinbefore described with reference to the accompanying drawings.
