Abstract
An adaptor for connecting conduits either side of the wall 10 of, for instance, a meter box has connections 2, 3 at each end. A central portion of the body 1 of the adapter has a groove 6 into which a locking member 13 suitably formed as a C shaped clip is arranged to be fitted. Between the groove and the locking member is a chamfered interaction formed by a chamfered surface or surfaces 11, (14) so as to cause the locking member to press the adaptor into firm engagement with the wall into which it is fitted. This provides a rigid securing of the adapter in the wall. <IMAGE>
Description
AN ADAPTOR FITTING
The present invention relates to an adaptor for connecting two conduits.
Adaptors for connecting conduits either side of a wall of for instance a meter box are known from GB Patent
Specifications Nos. 2117470B and 2125506B. Somewhat similar adaptors for connecting hose lines either side of bulkheads are also known from GB Patent Specification Nos.
2065812A. A conventional gas adaptor is shown in Figure 1 of GB 2117470B in which a tubular body has a plastics gas pipe connection at one end and a threaded end connection at the other end for connection to a meter box equipment.
A central portion of the body has a flange and a threaded portion on which is a nut. To secure the adaptor to a meter box, the body is inserted through a hole in the box, a thick rubber washer and then a metal washer is threaded over the body. The nut is then placed over the body and screwed tight to clamp the body in the hole. The expense of this conventional adaptor has resulted in a design having a snap fitted flange arrangement with a 'C' shaped split washer shown in GB 2117470B or an expanding skirt arrangement as shown in GB 2125506B. In both these arrangements it is necessary to take up tolerances in the box wall with '0' rings.
An object of the present invention is to provide an improved adaptor which is economical to manufacture and eliminates the need for washers or '0' rings.
An adaptor for connecting two conduits comprises a tubular body with connections at each end, a central portion of the body having a flange and a groove formed in a cylindrical portion of the central portion, the cylindrical portion being of smaller diameter than the flange, a locking member arranged to fit into the groove, the groove and/or the locking member being chamfered so as to cause the locking member to be urged relatively towards the flange when fitted into the groove.
An advantage of the invention is that on fitting the locking member on to the adaptor body a wall of a meter box between the locking member and the flange can be firmly held by the action of the chamfer(s) without the need of any resilient washer or '0' ring. In particular the locking member acts in a radial direction to cause axial take-up.
Preferably the locking member is a resilient 'C' shaped clip with the gap having a smaller dimension than the diameter of the bottom of the body groove.
The locking member is preferably chamfered at an angle of between 200 and 450 and preferably about 300 on one face.
Preferably the groove is chamfered at a corresponding angle to the locking member on a side facing the flange.
The distance between the flange face and the groove on the cylindrical portion is such as to provide an axial dimension slightly less than the minimum wall thickness of for instance a meter box wall.
An embodiment of the invention will now be described with reference to the accompanying drawings in which:
Figure 1 shows a partial axial cross section and
partial side elevation of an adaptor according to
the invention fitted to a wall of a meter box,
Figure 2 shows a plan view of a locking 'C' shaped
clip member for the adaptor shown in Figure 1, and
Figure 3 is a partial cross section taken at AA of
the clip of Figure 2.
The adaptor shown in Figure 1 has a tubular body 1, with connections 2 and 3 at its ends and an integral flange 4 on a central portion 5. The connections are for pipes or other conduits. A groove 6 is formed in a cylindrical portion 7 of the central portion. This cylindrical portion is of a smaller diameter than the flange so that it can be pushed through a hole 9 in a wall 10 of a meter box.
The groove 6 is chamfered at side 11 at angle of between 20" and 450 and preferably about 300 to face 12 of the flange.
A 'C' shaped nylon clip or locking member 13 having a chamfered inner surface 14 of the same angle, preferably about 300 as the groove side 11 is shown in Figures 2 and 3 with leading chamfers 15 for assisting insertion in the groove. The internal dimension between surfaces 17 isless than the diameter at the bottom of the body groove.
The side 16 opposite chamfered surface 14 is flat and when in place in the groove abuts against the meter box wall. The clip or locking member is urged tightly against the wall by means of its resilience acting to close and the wedging action between the chamfered surfaces 11 and 14.
The dimensions of the groove 6 in the body 1, its relative position to the flange 4 and the dimensions of the clip 13 re such that the tolerance of the meter box wall around the hole 9 can be fully accommodated and is radially and axially secure under all normal operating conditions.
The outer shape of the clip 13 whilst shown as approximately circular may be shaped in other ways for instance can have straight edges.
Whilst the adaptor of the invention is described as being fitted and used in a meter box, it can also be used as a fitment for securing pipes in any other bulkhead or to a bracket. Alternatively it can be used for connecting pipes and equipment having conduits.
The advantage of the adaptor according to the invention is that it not only eliminates the need for a flat rubber washer or '0' ring with cost advantages. It also provides a rigid and positive securing of the adaptor in a wall.
Claims (7)
1. An adaptor for connecting two conduits comprising a tubular body with connections at each end, a central portion of the body having a flange and a groove formed in a cylindrical portion of the central portion, the cylindrical portion being of a smaller diameter than the flange, a locking member arranged to fit into the groove, the groove and/or the locking member being chamfered so as to cause the locking member to be urged relatively towards the flange when fitted into the groove.
2. An adaptor as claimed in claim 1 wherein the locking member is a resilient 'C' shaped clip having a gap formed between extremities of the clip, the gap having a smaller dimension than the diameter of the body groove.
3. An adaptor as claimed in claim 1 or 2 wherein the locking member is chamfered at an angle of between 200 and 450 and preferably about 300 on one face.
4. An adaptor as claimed in any one of claims 1 to 3 wherein the groove is chamfered at a corresponding angle to the locking member on a side facing the flange.
5. An adaptor as claimed in claim 3 wherein the extremities of the clip each have a leading edge which is chamfered for assisting insertion in the body groove.
6. An adaptor as claimed in any one of claims 1 to 5 wherein the locking member has an outer partly circular shape.
7. An adaptor for connecting two conduits substantially as described with reference to the accompanying drawings.
