PIPE SUPPORT FIELD

The present disclosure relates to a clip or other device for supporting a pipe or conduit of variable diameter on a support surface.

BACKGROUND

The use of clips, saddles, and clamps to hold a pipe or conduit against a support surface such as masonry, brick, timber, steel is known. Typically such holding devices have a curved pipe holding recess that can receive a pipe or conduit and a method of fixing the device to a substrate surface. Generally the holding device has an aperture through which a fastener such as a nail or screw can pass. Holding devices are sized to receive a pipe or conduit of a specific diameter such that the pipe or conduit is firmly held against the support surface. If the pipe or conduit has a smaller diameter than that prescribed for the pipe or conduit will fit loosely in the device. The device cannot be used with a conduit or pipe having a larger diameter because the pipe cannot be received in the holding device.

It has been recognised within the plumbing and gas fitting industry that it would be desirable to provide a clip, saddle or other holding device that can accommodate a pipe or conduit of different diameters. There have been a number of proposals to address thisissue. Some approaches have been to provide an internal resilient arm(s) or tongue that extend into the pipe holding recess. This allows a pipe of smaller diameter to be retained between the extending tongue and an opposite side wall of the recess. When a pipe of larger diameter is to be held the resilient tongue deforms to accommodate the larger diameter.

Another approach has been to provide an insert that is placed in the pipe holding recess so as to reduce the effective diameter thereof.

The reference to prior art in the background above is not and should not be taken as an acknowledgment or any form of suggestion that the referenced prior art forms part of the common general knowledge in Australia or in any other country.

DETAILED DESCRIPTION

Reference throughout this specification to 'one embodiment' or'an embodiment' means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the present invention. Thus, the appearance of the phrases'in one embodiment' or'in an embodiment' in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more combinations.

In compliance with the statute, the invention has been described in language more or less specific to structural or methodical features. It is to be understood that the invention is not limited to specific features shown or described since the means herein described comprises preferred forms of putting the invention into effect. The invention is, therefore, claimed in any of its forms or modifications within the proper scope of the appended claims (if any) appropriately interpreted by those skilled in the art.

Figures 1 to 7 show a clip 10 of one aspect of the disclosure. The clip 10 has a clip body 12 that defines a first curved or arcuate pipe receiving recess or pipe holding recess 14 having a first effective diameter, D1 that corresponds to the diameter of the full circle of the arc.

The body 12 has a base part 11 below the pipe receiving recesses that spaces a pipe held therein from the support surface so as to protect the pipe surface from damage caused by abrasion against the support surface.

The clip 10 has two curved or arcuate arms 16, 18 spaced laterally on either side or end of the body 12 by means of a link 17. Each arm 16, 18 defines a further curved pipe receiving recess 19 (on each end of the first pipe receiving recess 14) having a second diameter D2. The effective diameter D2 of the second pipe receiving recess 19 is less that of the first pipe receiving recess 14.

In use, the first pipe holding recess 14 in the body 12 may accommodate for example a 20mm pipe. The second effective diameter D2 of the second pipe receiving recess 19 may accommodate a 16mm pipe.

The second effective diameter D2 is an internal diameter of the arms 16, 18. The arms 16, 18 further define an outer diameter D2o. The outer diameter D2o is the same as D1. This means that there is nothing projecting into the first recess and may facilitate clipping a pipe therein. This may be compared to prior art clips for accommodating two different pipe diameters that have a flexible tongue extending into pipe receiving recess.

The body 10 has two sides that for convenience are referred to as the front and rear sides in the Figures. The rear side comprises an outer support section 20 with a curved inner wall that defines one side of the first pipe receiving recess 14. An aperture 24 extends through the support section 20 to allow a screw to pass therethrough. An anchor or wall plug 22 extends from the support section 20 that communicates with the aperture 24. Anchors or wall plugs 22 enable a screw to be inserted into a material that is porous or brittle such as masonry. The top of the aperture 24 is countersunk for receiving the head of a fastener so that it does not project up above the support section 20. The support section 20 is substantially non-resilient, and there is essentially no elastic deformation of the support section 20 when a pipe having a first diameter is inserted into the first pipe receiving recess or pipe holding recess 14.

The other or front side of the body 12 is defined by a curved member 21 with a curved inner wall that defines the other half of the recess 14. The outer curved member 21 has a reinforcing rib 26 on an outer surface thereof. The curved member 21 is resilient such that it undergoes elastic deformation so as to allow a pipe of a first diameter to be placed or clipped therein.

The clip 10 is made from a thermoplastics material such as polypropylene that is firm but has a degree of resilience so as to allow a pipe to be press or snap fitted into the pipe holding recesses 14, 19 and firmly hold the pipe in place.

The pipe holding recess 14 in the body 12 of the clip 10 can hold a pipe or conduit of a first diameter D1. The resilient curved arms 16, 18 when in the non-elastically deformed position can hold a pipe of smaller diameter than the pipe holding recess 14 of the body 12. If a pipe of the larger diameter D1 to be held by the body, the resilience of the arms 16, 18 allows them to elastically deform so as to accommodate the larger size.

The arms 16, 18 are more resilient than member 21. This allows the arms 16, 18 to deform sufficiently so as to accommodate the larger pipe. The arms 16, 18 each have a width that is less than that of the body 12. However, it will be appreciated that by having two arms spaced apart compensates for their lack of width, and enables them to firmly holds a pipe having a second diameter.

Figures 7a and 7b schematically show the bottom view of the clip 12 holding a pipe having a second pipe diameter P2 and first pipe diameter P1 respectively. Deformation of the arms 16, 18 to accommodate the larger pipe diameter P1 may be seen in Figure 7b.

Figures 8 to 14 show a clip 50 according to a further embodiment of the invention. The clip 50 has the same arrangement of the first recess 14 and further recesses 19 defined by the curved arms 16 as the clip 10 of Figures 1 to 7. Further the same reference numerals are used to refer to the same components unless otherwise indicated.

The clip 50 does not have an anchor and has a hinge member 52 that closes the first pipe holding recess 14 in the body 60. The hinge member 52 has a flat base 54 for abutting against the support surface and a curved inner 56 surface that is complementary to the curved surface of a pipe. The hinge member 52 is attached to the clip body 12 at a hinge point 58. In use, the hinge member 52 is folded back under the pipe and the clip 10 is then fixed to the support surface. The hinge member 52 keeps the pipe from contacting the substrate or support surface, in particular for a horizontal run of pipe.

Figures 15 to 21 show a clip 70 in accordance with yet another embodiment of the invention. The clip has the same arrangement of first 14 and further recesses 19 defined by curved arms 16, 18 and anchor 22 as the clip 10 of Figures 1 to 7. Once again, the same reference numerals are used to refer to the same components unless otherwise indicated.

The clip has a hinge member 74 for closing the recess 14. In this aspect, the hinge 74 member cannot extend across the full extent of the base of the body 22 because of the presence of the anchor 22. Figure 19a shows the hinge member 74 in the open position.

Figures 22 to 28 show a still further clip 80 in accordance with yet another embodiment of the invention that does not have an anchor or a hinge member. The clip 80 has the same arrangement of first 14 and further recesses 19 defined by curved arms 16 and anchor 22 as the clip 10 of Figures 1 to 7and the same reference numerals are used to refer to the same components

Figure 29 shows a further clip 90 in accordance with yet another embodiment of the invention. The clip 10 is in the form of a saddle with outward extending feet 92 with an aperture 94 in each foot 92 for receiving a fastener. The clip 90 has the same arrangement of first 14 and further recesses 19 defined by curved arms 16, 18 as the clip 10 of Figures 1 to 7 and the same reference numerals are used to refer to the same components.

Figure 30 shows a further clip 100 in accordance with yet another embodiment of the invention. The clip 100 has the same arrangement of first 14 and further recesses 19 defined by curved arms 16, 18 as the clip 10 of Figures 1 to 7 and the same reference numerals are used to refer to the same components.

The clip 100 has an aperture 102 through the top part of the body 12 and communicates with the first pipe receiving recess or pipe holding recess 14.

It may be appreciated that having two separate pipe holding arms on either side of and axially spaced from the body that is centrally positioned between the two arms, a smaller pipe can be held in a more secure manner than if for example, there was a simple single tongue extending into the pipe holding recess in the body. It also does not interfere with the structure of the clip body, allowing the central body to be stronger, which then in turn provides further and stronger support for a held pipe.

In the present disclosure and claims, the term "comprising" may be understood to have a broad meaning similar to the term "including" and will be understood to imply the inclusion of a stated integer or step or group of integers or steps but not the exclusion of any other integer or step or group of integers or steps unless the context indicates otherwise. This definition also applies to variations on the term "comprising" such as "comprise" and "comprises".

In the present disclosure and claims, the term "clip" may be interpreted broadly and may include any suitable pipe or conduit retainer or holder such as a clip, clamp, saddle or the like.

It will of course be realised that the above has been given only by way of illustrative example of the invention and that all such modifications and variations thereto, as would be apparent to persons skilled in the art, are deemed to fall within the broad scope and ambit of the invention as is herein set forth.
