Description

[0001] Mounting System

[0002] Field of the Invention

[0003] The invention relates to a system for mounting an article to a surface, and in particular to a system for mounting pipework and electrical equipment to a rail.

[0004] Background of the Invention

[0005] There is currently no standardised method for the installation of pipework in domestic and small commercial installations. In any installation, pipes are required to be supported or clipped at regular intervals to prevent damage caused by movement. Typically, offcuts of timber are used which can be fixed into position, for example across joists, and then individual plastic pipe clips can be fixed to the timber with screws. Where the level of the pipe needs to be raised, for example to allow a straight run to be fitted, then several pieces of timber are often stacked and fixed together in order to support the raised pipe. These methods are time consuming since each clip must be individually fixed to a supporting structure. In addition, the resulting installation is often unsightly.

[0006] Larger commercial installations benefit from a standardised method of securing pipework, usually using a combination of metal rails and clip supports or extendible pipe brackets which are connected to the rails, for example using spring channel nuts. However, these types of installation are time consuming to install and are expensive to use on smaller commercial or domestic applications, as well as being more complicated than is necessary in such installations.

[0007] EP0795708 describes pipe clamps which include coupling means for coupling multiple clamps together. The clamps also include grooves which allows the clamps to slide onto a C- shaped rail. CN219119996U describes an adjustable pipe clamp assembly comprising a number of pipe clamps which slide onto a T-shaped rail.

[0008] It would be desirable to provide an improved and simplified method for installation of pipework which would reduce installation times as well as cost. Summary of the Invention

[0009] According to an aspect of the invention there is provided a system for mounting an article to a surface, the system comprising: at least one first component, the first component including a rail portion, wherein the rail portion comprises an elongate substantially U-shaped channel defined by a pair of upstanding, opposing side walls, each side wall having an inwardly extending lip; means for attaching the first component to a surface; at least one adaptor, the adaptor comprising a base, and means for attachment to the rail portion of the first component; wherein the means for attachment to the rail portion comprises: a pair of upstanding opposing side walls extending from the base, and connected to the base at a first end; a pair of wings, each wing extending outwardly from a second end of each side wall; and a recessed portion in each of the side walls located adjacent to each of the wings; wherein the adaptor further comprises means for supporting an article extending from the base and located between the pair of upstanding side walls; wherein the at least one adaptor is configured such that each of the side walls can flex with respect to base; wherein the at least one adaptor is configured to be inserted into the channel of the rail portion of the first component such that the lips of the rail portion locate in the recessed portions of the at least one adaptor; and wherein, when attached to the rail portion of the first component, each wing of the or each adaptor is located adjacent to an external surface of the inwardly extending lip of the rail portion.

[0010] Each of the side walls of the at least one adaptor has a thickness and each side wall may be connected to the base of the adaptor by a region of material which has a thickness which is less than the thickness of the side wall. The reduced thickness of material allows the side walls and wings to flex with respect to the base of the adaptor.

[0011] Preferably, when the or each adaptor is attached to the rail portion of the first component, each wing of the or each adaptor extends beyond the side walls of the rail. This allows the adaptor to be easily removed from the rail portion.

[0012] Preferably, the at least one adaptor is formed from a plastics material. More preferably, the at least one adaptor is formed from a one-piece plastics moulding. The first component and the at least one adaptor may each be formed from a plastics material. Each of the first component and the at least one adaptor may be formed as a one-piece plastics moulding.

[0013] The at least one adaptor may include a first surface with a tapered profile on the side wall between the base and the recess, and a second surface with a tapered profile located between the base and the protrusion.

[0014] The opposing side walls of the rail portion may each include an inner surface with a tapered profile, where the side walls of the rail portion are configured to provide a complementary mating interface with the first and second surfaces of the at least one adaptor.

[0015] According to a further aspect of the invention there is provided a system for mounting an article to a surface, the system comprising: at least one first component, the first component including a rail portion, wherein the rail portion comprises an elongate substantially U-shaped channel defined by a pair of upstanding, opposing side walls, each side wall having an inwardly extending lip; means for ataching the first component to a surface; at least one adaptor, the adaptor comprising a base, means for supporting an article extending from the base, and first and second lip engagement means for engaging with a respective first and second inwardly extending lip of the rail portion of the first component; wherein the first lip engagement means comprises: a side wall extending from the base of the adaptor and connected to the base at a first end; a wing extending outwardly from a second end of the side wall, configured such that the side wall and wing can flex with respect to the base; and a recessed portion in the side wall, located adjacent to the wing; the recessed portion arranged to receive the first inwardly extending lip of the rail portion.

[0016] The means for supporting an article preferably extends from the base and is spaced apart from the side wall.

[0017] The second lip engagement means of the at least one adaptor may comprise a second recessed portion shaped to receive the second inwardly extending lip of the rail portion. The side wall and the second recessed portion are preferably located on opposing sides of the at least one adaptor.

[0018] The second lip engagement means of the at least one adaptor may comprise a protrusion configured to engage with the second inwardly extending lip of the rail portion. The side wall and the protrusion are preferably located on opposing sides of the at least one adaptor.

[0019] Engagement of the adaptor with the first and second inwardly extending lips of the rail is such that displacement of the adaptor relative to the rail portion is restricted.

[0020] Preferably, the side wall of the at least one adaptor has a thickness and the side wall is connected to the base of the adaptor by a region of material which has a thickness which is less than the thickness of the side wall. The reduced thickness of material allows the side wall and wing to flex with respect to the base of the adaptor.

[0021] Preferably, the at least one adaptor is formed from a plastics material. More preferably, the at least one adaptor is formed from a one-piece plastics moulding. The first component and the at least one adaptor may each be formed from a plastics material. Each of the first component and the at least one adaptor may be formed as a one-piece plastics moulding.

[0022] The means for supporting an article may include a surface for supporting a pipe.

[0023] The means for supporting an article may include an aperture for receiving a fastening means for fastening an article to the adaptor.

[0024] The means for supporting an article may include push-fit clip means and the article to be mounted may include an aperture shaped and dimensioned to connect to the clip means of the adaptor. The push-fit clip means may comprise a pair of resilient legs which extend away from the base of the adaptor. Each leg may include a locking projection and a tapered sliding surface.

[0025] The first component of the system may include a rail portion and means for attachment to the rail portion of a further first component.

[0026] Preferably, when the or each adaptor is attached to the rail portion of the first component, each wing of the or each adaptor extends beyond the side walls of the rail. This allows the adaptor to be easily removed from the rail portion.

[0027] The at least one adaptor may include a first surface with a tapered profile on the side wall between the base and the recess, and a second surface with a tapered profile located between the base and the protrusion.

[0028] The opposing side walls of the rail portion may each include an inner surface with a tapered profile, where the side walls of the rail portion are configured to provide a complementary mating interface with the first and second surfaces of the at least one adaptor.

[0073] Detailed Description of the Preferred Embodiments

[0074] Figure 1 illustrates a low-pro file rail 10 comprising a substantially U-shaped elongate channel comprising a base 14, and a pair of spaced apart upstanding parallel side walls 12. The side walls 12 are fixed to the base along a first elongate edge. A second elongate edge of each of the side walls 12 is provided with an inwardly extending lip 16, which extends at substantially right angles to each of the side walls. The base 14 of the rail 10 includes a plurality of apertures 18 for securing the rail to a surface such as a wall, floor, or joist using fasteners, such as screws (not shown) .

[0075] Figure 2 illustrates an adaptor 20 for mounting an article to the rail 10. The adaptor illustrated in Figure 2 comprises rail attachment means in the form of a base 22, a pair of walls 26 extending from the edges of the base 22 at an angle of substantially 90 degrees, and a pair of wings 24 extend outwardly from each wall, from the edge of the wall which is distal from the base. Each wing extends outwards at an angle of substantially 90 degrees to the wall to which it is connected, such that each wing is substantially parallel to the base 22. The walls 26 and wings 24 are connected to the main body 30 of the adaptor 20 by a web 21, which is a region of reduced thickness material which extends adjacent to each wall 26. The adaptor is preferably formed from a one-piece plastics moulding, and together, the walls and wings can flex about the web 21. At the underside of the junction between each wall and wing there is an elongate recess 28. When the adaptor 20 is inserted into the rail 10, as shown in Figure 3, each lip 16 of the rail locates inside an elongate recess 28 on the adaptor. Preferably, the base 22 of the adaptor 20 rests on the base of the rail and the wings 24 locate adjacent to the upper, external surface of the lips 16 of the rail. Each side wall 26 preferably includes an outer surface 26a with a tapered profile, this surface being located on the side wall between the base and the recess 28. The tapered surfaces help insertion and removal of the adaptor from the rail, and may help the adaptor engage with the rail as discussed later in relation to the low profile rail illustrated in Figure 20.

[0076] The adaptor illustrated in Figure 2, 3, and 4 includes a central portion 30 which is spaced apart from the side walls 26. The central portion 30 has an upper surface 32, which may have a V-shaped profile, for supporting a pipe 36 (see Figure 4) and an aperture 34 through which fastening means such as a cable tie 38 can be inserted.

[0077] To insert the adaptor 20 onto the rail 10 the wing portions 24 are squeezed together by hand, causing the walls 26 to move inwards towards the central part, as illustrated in Figure 5b. The adaptor can then be easily slid onto the rail, and along the rail into a desired position. When the wings 24 are released, the lips 16 of the rail 10 locate in the recesses 28 underneath the wings 24, locking the adaptor 20 in place, as illustrated in Figure 5a. Alternatively, the adaptor 20 can be pressed downwards onto the rail. The outside edges of the walls 26 are tapered and pressing down causes the walls 26 to move inwards towards the central portion of the adaptor until the lips 16 of the rail 10 locate in the recesses 28, as illustrated in Figure 5a. The reverse process can be employed for removing the adaptor 20 from the rail 10: by pulling up on the wings 24 as shown in Figure 5b, the lips 16 of the rail 10 are released from the recesses 28 of the adaptor 20, allowing the adaptor to be removed from the rail either as illustrated in Figure 5c or by sliding the adaptor off the end of the rail. Preferably, as illustrated, the wings 24 extend beyond the lip 16 and the side walls 12 of the rail to make removal of the adaptor easier.

[0078] Figure 6 illustrates an alternative adaptor 40 which includes a push fit clip. The push fit clip adaptor comprises rail attachment means which are the same as described in relation to the embodiment of Figure 2, and are labelled with the same reference numerals. The push fit clip adaptor 40 of Figure 6 differs from the previously described adaptor in that it includes a push fit clip 41 in the form of a pair of resilient legs 42 which extend away from the central portion 30 of the adaptor 40. Each leg 42 includes a locking projection 44 and a tapered sliding surface 45. The push fit clip part 41 is shaped and dimensioned to connect with a complementary aperture 48 on an object such as an electrical back box 46, as shown in Figure 8. To mount the electrical back box 46 on the push fit clip adaptor 40, the legs 42 of the push fit clip are aligned with an aperture 48 on the electrical back box 46. Pressing down allows the sliding surface 45 of the legs to slide over the sides of the aperture 48, pushing the resilient legs together. When the edges of the aperture located underneath the locking projections 44 of the resilient legs 42 spring back into position and the electrical back box is locked into place on the push fit clip adaptor 40. The electrical back box can be removed by pinching together the ends of the legs 42 to allow the edges of the apertures to disengage from the locking projections, so that the electrical back box can be removed. Other objects, such as a cable trunking conduit 47 provided with similar apertures 48, as illustrated in Figure 9, could also be connected to the push fit clip adaptor 40 in the same way. Figure 10a and 10b illustrate a further alternative adaptor 50 which includes an aperture 52 for receipt of a pipe or wiring conduit. This adaptor also comprises rail attachment means which are the same as described in relation to the embodiment of Figure 2, and are labelled with the same reference numerals. Figure 11 illustrates the adaptor 50 installed on a low-profile rail 10.

[0079] Figures 12a and 12b illustrate a further alternative adaptor 54 which includes a pair of resilient arms 56 for receiving a pipe 36 or wiring conduit as illustrated in Figure 34. The adaptor may include an aperture 58 through which fastening means such as a cable tie 38 can be inserted. As with the other adaptors, each side wall 26 preferably includes an outer surface 26 with a tapered profile, this surface being located on the side wall between the base 31 and the recess 28. The tapered surfaces help insertion and removal of the adaptor from a rail, and may help the spacer rail engage with the rail as discussed later in relation to the low profile rail illustrated in Figure 20.

[0080] Figures 13a and 13b illustrate a spacer rail 60 which can be attached to a low-pro file rail 10, allowing the height of the rail to which an object is to be attached to be raised. As shown in Figure 13b, the lower portion 61 of the spacer rail includes the same rail attachment means as the adaptors described previously, namely a base 62, a pair of walls 66 extending from the edges of the base 62 at an angle of substantially 90 degrees, and a pair of wings 64 which extend outwardly from each wall, from the edge of the wall which is distal from the base. Each wing extends outwards at an angle of substantially 90 degrees to the wall to which it is connected, such that each wing is substantially parallel to the base 62. The walls 66 and wings 64 are connected to the main body 67 of the adaptor 60 by a web 69, which is a region of reduced thickness material which extends adjacent to each wall 66. Together, the walls and wings can flex about the web 69. At the underside of the junction between each wall 66 and wing 64 there is an elongate channel 68.

[0081] Each side wall 66 preferably includes an outer surface 66a with a tapered profile, this surface being located on the side wall between the base 62 and the channel 68. The tapered surfaces help insertion and removal of the spacer rail from another rail, and may help the spacer rail engage with the rail as discussed later in relation to the low profile rail illustrated in Figure 20.

[0082] The upper portion 63 of the spacer rail 60 comprises a low-profile rail including a pair of spaced apart upstanding parallel side walls 12’. The side walls 12’ are each provided with an inwardly extending lip 16’, which extends at substantially right angles to each of the side walls.

[0083] Figures 14a and 14b illustrate a spacer rail 60 connected to a low-profile rail 10, with each lip 16 of the low-profile rail 10 located in the elongate channels 68 of the lower portion 61 of the spacer rail 60. Several spacer rails 60 may also be connected together to raise the height of the rail further, as illustrated in Figures 15a and 15b, where a first spacer rail 60 is connected to a second spacer rail 60, with the rail lips 16’ of the first spacer rail located in the elongate channels 68 of the lower portion of the second spacer rail. Any of the adaptors described herein can then be connected to the uppermost low-profile rail portion 63 of the uppermost spacer rail.

[0084] Figures 16a and 16b illustrate an alternative low-profile rail 70 for use with the system of the invention. This rail includes a vertical fixing surface 72 extending from one edge of the rail. Such a rail is useful for fixing to vertical surfaces such as joists. The fixing surface 72 includes a plurality of apertures 74 for receipt of fasteners (not shown). In all other aspects the rail features are identical to those described in relation to Figure 1 and are labelled with like reference numerals.

[0085] Figure 17 illustrates a rail end bracket 75 suitable for fixing rails to vertical surfaces such as joists. The rail end bracket 75 resembles a spacer rail 60 as illustrated in Figure 12a, with one end attached to a substantially vertical plate 77. The vertical end plate 77 includes a plurality of apertures 78 for receipt of suitable fasteners. The lower portion 78 of the spacer rail portion of the rail end bracket includes rail attachment means as previously described and is suitable for connection to either low-profile rails 10 or spacer rails 60. The upper portion 79 of the spacer rail portion of the rail end bracket 75 is suitable for connection to adaptors or spacer rails. Figure 18a illustrates a rail end bracket 75 with a spacer rail 60 connected to the lower portion 78 of the rail end bracket. Figure 18b illustrates a rail end bracket 75 with a spacer rail 60 connected to the upper portion of the rail end bracket. The connection between the two parts is the same as described in relation to Figure 15a.

[0086] Figure 19 illustrates a rail end bracket 74 with a low-profile rail 10 connected to the lower portion of the rail end bracket. The connection between the two parts is as described in relation to Figure 13a.

[0087] Figure 20 illustrates an alternative example of a low-profile rail 10’ which is similar to that described in relation to Figure 1, however in this version the internal walls 17 of the rail have a tapered profile. Preferably, the tapered profile of the internal side walls of the rail are shaped to correspond to tapered surfaces (26a, 108, 109) of the adaptor in order to provide a complementary mating interface with the first and second surfaces of the at least one adaptor. Friction between the mating surfaces helps to prevent the adaptor sliding on the rail. Figure 21 illustrates different adaptors installed on the rail of Figure 20, and Figure 22 is an end on view, illustrating more clearly the mating surfaces with tapered profiles.

[0088] Figure 23 illustrates a pair of spacer rails 60’ similar to those described in relation to Figures 13a to 15b, the rails having the tapered internal walls 17 as described in relation to Figure 20. The lower portion 61’ of the spacer rail includes the same rail attachment means as described previously.

[0089] Figure 24 illustrates an alternative low-profile rail 70’ for use with the system of the invention in a similar way to that described in relation to Figures 16a and 16b, the rail having tapered internal walls 17’ as described in relation to Figure 20. This rail includes a fixing surface 72’ extending from one edge of the rail, substantially perpendicular to the base of the rail. Such a rail is useful for fixing to vertical surfaces such as joists. Figure 25 illustrates a pair of rail end brackets 75’ suitable for fixing rails to vertical surfaces such as joists, in a similar way to that described in relation to Figure 17, the rail end brackets having the tapered internal walls 17 as described in relation to Figure 20.

[0090] Figure 26 illustrates an alternative adaptor 80 for use on a low-profile rail system. The rail connection means for this adaptor is similar to that described previously. The adaptor comprises a base 82, with one wall 86 extending from one edge of the base 82 at an angle of substantially 90 degrees thereto, adjacent to a first face of the main body 85 of the adaptor.. A wing 84 extends outwardly from the edge of wall 86 which is distal from the base 82. The wing 84 extends outwards at an angle of substantially 90 degrees to the wall 86 such the wing is substantially parallel to the base 82. The wall 86 and wing 84 are connected to the main body 81 of the adaptor 80 by a web 83, which is a region of reduced thickness material which extends adjacent to the wall 86. Together, the wall and wing can flex about the web 83. At the underside of the junction between the wall 86 and the wing 84 there is a first elongate recess 88 for engagement with one of the inwardly extending lips of the rail portion. The opposing face of the main body of the adaptor 80 comprises a second elongate recess 87 for engagement with a second of the inwardly extending lips of the rail portion. The side wall 86 preferably includes an outer surface 108 with a tapered profile, this surface being located on the side wall between the base and the recess 88. The tapered surface help insertion and removal of the adaptor from a rail, and may help the adaptor engage with the rail as discussed previously. In summary, one half of the rail connection means is the same as that described previously, and the other half comprises a recess 87 in the opposite side of the adaptor.

[0091] As illustrated in Figure 27, when the adaptor 80 is inserted into the rail 10 a first lip 16 of the rail 10 locates inside the first elongate recess 88 on the underside of the wing 84 on the adaptor 80 and the second lip 16 locates inside the second elongate recess 87. Preferably, the base 82 of the adaptor 80 rests on the base of the rail and the wing 84 rests on the upper surface of the first lip 16 of the rail. To insert the adaptor 80 onto the rail 10 the wing portion 84 is pulled inwards and upwards by hand, causing the wall 86 to flex about the web 82 and to move inwards towards the main body 81 of the adaptor. The adaptor 80 can then be slid onto the end of the rail 10 by locating the second lip 16 of the rail into the second elongate recess 87. When the wing 84 is released, the first lip 16 of the rail 10 locates in the first elongate recess 88 underneath the wing 84, locking the adaptor 80 in place.

[0092] Alternatively, the adaptor 80 could be inserted onto the rail 10 by locating a lip of the rail 10 into the second elongate recess 87 of the adaptor 80 and then pulling inwards and upwards on the wing portion 84, causing the wall 86 to flex about the web 82 and to move inwards towards the main body 81 of the adaptor, allowing the main body of the adaptor to be pressed into the channel of the rail , causing the first lip 16 to ride over the tapered part 108 of the wall 86 until the first lip 16 locates within the. recess 88 underneath the wing 84.

[0093] The reverse process can be employed for removing the adaptor 80 from the rail 10: by pulling up on the wing 84, the first lip 16 of the rail 10 is released from the first elongate recess 88 of the adaptor 80, allowing the adaptor to be removed from the rail by sliding the adaptor off the end of the rail, or by rotating the adaptor about the second elongate recess 87 and removing it from the channel of the rail. This type of rail attachment means could be applied to any of the adaptors or rails described herein. In the example illustrated in Figure 19, the adaptor comprises an upper surface 90, which may have a V-shaped profile, for supporting a pipe 36 (see Figure 28) and an aperture 92 through which fastening means such as a cable tie 38 can be inserted.

[0094] Figure 29a to 31b illustrate three examples of a further alternative adaptor 100, 110, 120 for use on a low-profile rail system which is similar to those illustrated in Figures 26 to 28. Like features are referred to with like reference numerals. Each adaptor 100, 110, 120 comprises a base 82, at a first side of the adaptor a wall 86 extends from one edge of the base 82 at an angle of substantially 90 degrees thereto, and adjacent to a first face of the main body 105 of the adaptor. A wing 84 extends outwardly from the edge of wall 86 which is distal from the base 82. The wing 84 extends outwards at an angle of substantially 90 degrees to the wall 86 such the wing is substantially parallel to the base 82. The wall 86 and wing 84 are connected to the main body 81 of the adaptor by a web 83, which is a region of reduced thickness material which extends adjacent to the wall 86. Together, the wall and wing can flex about the web 83. At the underside of the junction between the wall 86 and the wing 84 there is a first elongate recess 88 for engagement with one of the inwardly extending lips of the rail portion. At the opposite side of each adaptor 100, 110, 120, there is an elongate protrusion in the form of an elongate ledge 107 for engagement with a second of the inwardly extending lips of the rail portion. As illustrated best in Figures 32 and 33, the ledge 107 locates underneath the lip 16’ of the rail portion 10’, in a similar way to the recess 87 of the embodiment of Figures 26 and 27. Each of the adaptors 100, 110, 120 preferably include a first surface 108 with a tapered profile, this surface being located on the side wall between the base and the recess. Each of the adaptors 100, 110, 120 also preferably includes a second surface 109 with a tapered profile, this surface being located between the base and the protrusion. The tapered surfaces help insertion and removal of the adaptor from the rail.
