Abstract

A method of making a pipe joint comprises providing a mould for forming substantially half the joint split longitudinally, moulding half the joint including strengthening webs, and assembling two halves so moulded to form the finished pipe joint. Moulding the joint in two complementary halves (12) enables strengthening webs (22) to be produced within the elbow, which is difficult or impossible with the conventional injection moulding technique. Since the webs can be designed to provide the strength where necessary, the thickness of the remainder of the elbow can be reduced, leading to an overall saving in weight and material. Moreover, by careful choice of the shape and positioning of the strengthening webs, a single mould is sufficient to produce both halves of the joint. By these means, savings of over 50 % on the cost of conventionally produced joints can be made.

Description

PIPE JOINT
This invention relates to a pipe joint and in particular relates to a method of forming a joint for pipes or tubes by moulding.
Pipes and tubes often need to be joined, particularly at corners, to make larger structures. Pipe joints for doing this job may be straight ("straight couplers") or angled, usually at 90°, ("elbows") . In a particular end use, for jointing tubes to produce a frame-work, for example to hang the net of a five-a-side football goal, the elbows used for the corners have conventionally been moulded in one piece from a plastics material, for example by injection moulding. The extremities of the elbows are of a diameter which is a close fit within the bore of the tubing to be joined, and shoulders are formed against which the ends of the respective tubes abut when the elbow is in place.
In order for an elbow of this type to have sufficient strength, a considerable amount of plastics material must be employed. Moreover the mould necessary is relatively expensive in terms of tooling.
The invention seeks to provide a method of making a pipe joint, and a pipe joint so made, improved in the above respects.
According to the present invention there is provided a method of making a pipe joint which comprises providing a mould for forming substantially half the joint split longitudinally, moulding half the joint including strengthening webs, and assembling two halves so moulded to form the finished pipe joint.
Moulding the joint in two complementary halves enables strengthening webs to be produced within the elbow, which is difficult or impossible with the conventional injection moulding technique. Since the webs can be designed to provide the strength where necessary, the thickness of the remainder of the elbow can be reduced, leading to an overall saving in weight and material. Moreover, by careful choice of the shape and positioning of the strengthening webs, a single mould is sufficient to produce both halves of the joint. By these means, savings of over 50% on the cost of conventionally produced joints can be made.
The invention further includes a pipe joint so-produced.
The pipe joint of the invention may be a conventional 90° "elbow" or may be a "straight coupler" or other desired shape. Moreover, although a two-way joint is the commonest, three-way, four-way, five-way, and six-way joints can be produced.
The joints may be produced from thermoplastic materials such as polyolefins, PVC, nylon, or the like, or thermo-setting materials such as phenolic resins.
The halves may be moulded with complementary snap fit means but, since in use the joints normally fit within the bores of the tubes or pipes to be joined, they are held together in place and in these circumstances it is not therefore necessary to lock or adhere them together prior to use.
The pipes or tubes to be joined may be of any section, e.g. oval or square, as well as round.
The invention will be described further, by way of example, with reference to the accompanying drawings, in which:
Figure 1 is a perspective view of a pipe joint half in accordance with the invention;
Figure 2 is a sectional view equivalent to figure 1; and Figure 3 is a similar view to figure 2 of a three-way joint.
Referring to the drawings, in particular figures 1 and 2, a two-way pipe joint or elbow is formed from two halves each generally designated 10 and formed by moulding. Each half 10 comprises a bend portion 12 and two straight portions 14,16. The straight portions 14,16, when the pipe joint is assembled, form externally smooth cylinders and fit closely within the bore of a pipe or tube to be joined (not shown) . Shoulders 18,20 are formed at the ends of portions 14,16 to provide stops for the ends of the respective pipes. The bend 12 is moulded with a web 22 which is off-set from the central radius of the bend for reasons which will be explained hereinafter. The portion 14 contains a longitudinal strengthening web 24 and two transverse webs 26,28. The other portion 16 has longitudinal webs 30,32, each supported by transverse webs 34,36 with a gap 38 therebetween.
The shape of the half shown in figure 1 is such that, if two identical halves 10 are taken, and one is reversed with respect to the other, they are complementary in shape and interlock to produce an elbow with smooth external appearance. The web 24 goes through the gap 38 and abuts the webs 30 and 32. The webs 26,28 abut the webs 34 and 36, and the webs 22, each being offset from the central radius, abut one another. Normally no fixing means will be necessary since there is a sufficient interference fit between the two halves to hold them in place while they are placed into the pipes to be joined. Once in the pipes, they are held together by the pipes themselves. Alternatively, of course, mechanical fixing means may be provided, the halves may be made a snap fit, or a glue or adhesive may be used.
The presence of the strengthening webs, which can be placed where most needed, enables the strength of the joint of the invention to be sufficient using a relatively low weight of material .
Turning now to figure 3, a three-way joint is illustrated. This is made using one half 10 as illustrated in figure 1 together with a second half having an additional branch 40 as illustrated in figure 3. The branch 40 is provided with a cruciform strengthening web 42 which, as it lies in the same direction as the other webs, can therefore be moulded in one shot. If two such halves as illustrated in figure 3 are jointed together, a four-way joint is produced. By extension, five and six-way joints can be produced also.
The invention provides a simple, quick and inexpensive method of producing pipe joints having integral strengthening but which are nevertheless cheaper and quicker to produce than conventional joints. The joints of the invention may be used to join pipework to produce frames, racks, and the like in a wide variety of applications including, but not limited to, sporting applications such as goalposts, tent frames, storage racking systems, display racking systems, and the like.
