BEST METHOD OF PERFORMING THE INVENTION

[0036] By way of example, the present invention is now described in detail by reference to preferred embodiments.

[0037] FIG. 1 shows the cross section of a top guide 101 for use in the present system. Top guide 101 can be extruded in lengths of this cross-section from suitable materials such as an aluminium alloy. Top guide 101 includes a top plate 102. Each of a first end 103 and a second end 104 of top plate 102 may be adapted to be secured to structural elements of a building, such as framing defining a wall cavity, or a door frame. As shown, this may be achieved by each of first end 103 and second end 104 being thinner than the main body of top plate 102. One or more of first end 103 and second end 104 may also include one or more holes to allow the passage of securing means such as screws or similar through the first end 103 and/or second end 104 of top plate 102.

[0038] Integrally formed with top plate 102 of top guide 101 are a first wing 105 and a second wing 106. First wing 105 extends substantially perpendicularly from top plate 102. Typically each of the first and second wings shall extend from the top plate for substantially the same distance, such as 24-33 mm, for example 26-31 mm (such as about 27 mm). On the side closer to first end 104, first wing 105 may include one or more first engagement protrusions 107. The or each first engagement protrusion may be configured to optionally receive a fixing member (such as a screw) in or out of the plane of the cross section shown in FIG. 1. Such a fixing member (such as a screw) may be used to mount the top guide to a vertical support member, such as door jamb 203 where present. At an end of first wing 105 distal to top plate 102, a first bottom plate 108 extends from either side of first wing 106, substantially parallel to top plate 102.

[0039] Second wing 106 extends substantially perpendicularly from top plate 102 at a position closer to second end 104 than is first wing 105. On the side closer to second end 104, second wing 106 may include one or more second engagement protrusions 109. The or each second engagement protrusion may be configured to optionally receive a fixing member (such as a screw) in or out of the plane of the cross section shown in FIG. 1. Such a fixing member (such as a screw) may be used to mount the top guide to a vertical support member, such as door jamb 203 where present. At an end of second wing 106 distal to top plate 102, a second bottom plate 110 extends from either side of second wing 106, substantially parallel to top plate 102. First wing 105 and second wing 106 are separated so that there is a gap between first bottom plate 108 and second bottom plate 110. Together, top plate 102, first wing 105, and second wing 106 define a U-shaped cavity 111 dimensioned to receive a roller carriage, with the wheels of the roller carriage supported upon, and running along, first bottom plate 108 and second bottom plate 110.

[0040] Unlike a standard top guide for a cavity slider door, in top guide 101 both first wing 105 and second wing 106 are closer to second end 104 than to first end 102, so that top guide 101 is not symmetrical, but top plate 102 extends for a significant offset length between first wing 105 and first end 103. For example, the U-shaped cavity 111 between first wing 105 and second wing 106 may be about 20-30 mm (such as 26 mm). For example, the second end 104 may be about 10-30 mm from second wing 106. By way of another example, the second end 104 may be about 20-40 mm (such as about 31 mm) from second wing 106. For example, the first end 103 may be about 60-80 mm from first wing 105. By way of another example, the first end 103 may be about 70-90 mm (such as about 81 mm) from second wing.

[0041] FIG. 2 shows a plan view of a potential installation of a cavity slider door system according to the present invention. A wall cavity is defined between a first wall lining 201 and a second wall lining 202, adjacent a door frame and aligned therewith so that a single continuous top guide extends across the top of the door frame and along the top of the cavity. The structural elements supporting first wall lining 201, the structural elements supporting second wall lining 202, and the top guide together form a wall cavity body. Although the door frame is shown in this example as having an end jamb 203, it will be appreciated by one skilled in the to art that it will sometimes be architecturally desirable not to include this feature, for example when the cavity slider door is one of a pair that will meet together to fill a larger door frame. In such installations, a stop for the roller carriage may be included in the U-shaped cavity of the top guide at a desired location.

[0042] FIG. 3 shows the installation of the cavity slider system in the doorway. A doorway structural framing member 204 above the doorway is hidden on the sides by a first lining 205, which is continuous with first wall lining 201, and second lining 206, which is continuous with second wall lining 202. Top guide 101 extends along the doorframe with U-shaped cavity 111 accessible from the doorway. In this embodiment, top guide 101 is secured to doorway structural framing member 204 by passing screws through holes provided in each of first end 103 and second end 104 and into doorway structural framing member 204. Other known securing means could be used.

[0043] A first head jamb 207 is preferably made of timber. First head jamb 207 includes one or more grooves which receive first engagement protrusions 107, and is supported by first bottom plate 108 and engages with and conceals an edge of first lining 205.

[0044] A second head jamb 208 is preferably made of timber. Second head jamb 208 includes one or more grooves which receive second engagement protrusions 109, and is supported by second bottom plate 110 and engages with and conceals an edge of second lining 206.

[0045] In light of the unique proportions of the first head jamb 207 and second head jamb 208 which are configured to conceal most of the top plate 102, it may be convenient to be supplied with the top guide 101 and the first head jamb 207 and/or second head jamb 208 as a kit of parts. In one aspect the invention provides a kit of parts including:

[0046] (a) a guide for a sliding door, the guide including a plate, and two wings extending from the plate to define a cavity between the wings and the plate, characterised in that the cavity is closer to a second end of the plate than it is to a first end of the plate; and

[0047] (b) a first head jamb configured to conceal the plate between the first end and the wing closest to the first end and/or a second head jamb configured to conceal the plate between the second end and the wing closest to the second end.

[0048] Preferably the kit of parts is also provided with a roller carriage and cassette for fixing to a suspended door, wherein the cassette to adapted to be fixed to a recess in the top surface of the suspended door.

[0049] Generally the first head jamb 207 and the second head jamb will be supplied in the kit of parts. The kit of parts may be supplied as part of a complete door set.

[0050] Generally the first head jamb 207 and/or second head jamb 208 will extend from the top plate 101 a distance substantially equal to the distance that the respective first wing 105 and/or second wing 106 extend from the top plate 102.

[0051] Where the first protrusion 107 and/or second protrusion 109 are present it may be preferable to provide the respective first head jamb 207 and/or second head jamb 208 configured so as to substantially shroud the first protrusion 107 and/or second protrusion 109. Such a shrouding configuration may be provided in the form of a channel extending longitudinally along the first head jamb 207 and/or second head jamb 208 so as to provide a mated fit with the first protrusion 107 and/or second protrusion 109.

[0052] In some examples, the first head jamb 207 and/or second head jamb 208 may be provided with a longitudinal channel configured to engage with and conceal an edge of first lining 205 and/or second lining 208. In some embodiments this channel may extend a short distance (such as 5-20 mm) into the region between the top plate 102 and the head jamb. Advantageously this short extension allows a fixture (such as a hook, J-formed metal piece, or C-channel metal piece) extending from above (such as a ceiling) to hook around the undersurface of the top guide 101 to support its weight and enable the top guide 101 to be directly fixed to the ceiling.

[0053] It will be appreciated by one skilled in the art that different aesthetic appearances could be achieved. For example, instead of first head jamb 207 and second head jamb 208, the top guide 101 could engage directly with a ceiling lining, such as plasterboard. In some such instances the weight of the top guide (and door hanging therefrom) can be supported by a fixture (such as a hook, J-formed metal piece, or C-channel metal piece) extending from above (such as a ceiling and/or rafter beam). For example the fixture may hook around the undersurface of the top guide 101 to support its weight and enable the top guide 101 to be directly fixed to the ceiling. Such an embodiment may be particularly well suited to applications where having a door flush to ceiling finish is desired, since such a configuration will typically allow for more efficient ventilation, such as heating. Optional packing can also be included where necessary to position the top guide 101 for the desired aesthetic effect.

[0054] FIG. 4 shows the installation of the cavity slider system in the wall cavity. Cavity top structural member 209 may preferably be continuous with doorway structural framing member 204. Cavity top structural member 209 extends along the top of the cavity between first wall lining 201 and second wall lining 202. Top guide 101 extends along cavity top structural member 209 with U-shaped cavity 111 accessible from the cavity. In this embodiment, top guide 101 is secured to cavity top structural member 209 by passing screws through holes provided in each of first end 103 and second end 104, and into cavity top structural member 209. Other known securing means could be used.

[0055] A first side packing 210 includes one or more grooves which receive first engagement protrusions 107 and extend from top plate 102 to first bottom plate 108. First end 103 of top guide 101 is connected to a structural cavity body component 212 adjacent first side packing 210. Structural cavity body component 212 may be made of a material such as an H3.1 structural timber of plywood or strand board. First wall lining 201 is connected to the structural cavity body component 212 by known means.

[0056] Second end 104 of the top guide 101 is connected to a timber frame rail 211. Second wall lining 202 is connected to the timber frame rail 211 by known means.

[0057] FIG. 4 shows the position of door panel 213 when it is in the cavity. For clarity, the roller carriage is not shown in U-shaped cavity 111, nor are the connectors between the door panel 213 and the roller carriage. These are known features. As shown, there is a space 214 between door panel 213 and structural cavity body component 212. This space is an important feature of the present invention, because it provides a space within the wall cavity for services such as electrical wiring, or plumbing fittings, such as the examples described below in more detail.

[0058] First Example—Shower Installation

[0059] A first example of the use of the cavity slider system according to the present invention is for a door adjacent a shower area, and is described with particular reference to FIGS. 1, 2, 5 and 6.

[0060] The chosen aesthetic appearance for the doorway of the installation shown uses a first head jamb 207 engaged with first protrusion 107 on first wing 105 of top guide 101, a second head jamb 208 engaged with second protrusion 109 on second wing 106 of top guide 101, and a substantially vertical split jamb 313 along the edge of the doorway adjacent the wall cavity.

[0061] In this example, first wall lining 201 is adapted to form a lining for shower wall. This may be achieved by any of a variety known means, such as first wall lining 201 being a waterproof panel, or being coated with a waterproof coating or membrane and covered with tiles, or being a side wall of a prefabricated shower cavity made of acrylic or another material.

[0062] In order to provide a shower area adjacent the sliding door, first wall lining 201 is to be fitted with fittings, which in this example include a shower mixer 301, a shower hose 302, and a shower head support rail 303. (It will be appreciated that alternative fittings could be used, such as a fixed shower rose instead of the shower hose and shower head support rail, taps instead of a mixer, and that multiple water outlets and/or mixers or taps could be provided.)

[0063] For the shower to function, pipes carrying hot and cold water need to extend from the ceiling cavity to the shower mixer 301, and at least one pipe needs to extend from the shower mixer 301 to the shower hose 302. For the prior art models of cavity slider door, this would be impossible, because there is insufficient space within the wall cavity to allow pipes to run. However, the system of the present invention provides a space 214. A series of plumbing support rails 306, made of timber or a similar material, can be installed within the space 214.

[0064] As shown in FIGS. 2 and 5, in this example, shower inlet pipes 304 can run through the space 214 to the inlet ports on shower mixer 301, and a shower mixer outlet pipe 305 can also run through the space 214 from shower mixer 301 to the inlet port on shower hose 302, supported if necessary by connection to one or more plumbing support rails 306.

[0065] Shower head support rail 303 can be connected by conventional securing means such as screws through first wall lining 201 to engage with one or more (two in this example) plumbing support rails 306.

[0066] In this way, the cavity slider system of the present invention permits the installation of fittings for a shower area on the same wall cavity which houses the door panel in the open position. This provides a useful new option for designers and architects, which was not possible using the prior art systems.

[0067] Second Example—Vanity Installation

[0068] A second example of the use of the cavity slider system according to the present invention is for a door adjacent a wall on which a sink or vanity unit is to be installed, and is described with particular reference to FIGS. 1, 2, 5 and 6.

[0069] The chosen aesthetic appearance for the doorway of the installation shown uses a first head jamb 207 engaged with first protrusion 107 on first wing 105 of top guide 101, a second head jamb 208 engaged with second protrusion 109 on second wing 106 of top guide 101, and a substantially vertical split jamb 313 along the edge of the doorway adjacent the wall cavity.

[0070] In this example, first wall lining 201 may be a known type of wall lining, such as plasterboard, and may be partially additionally covered with a tile splashback or mirror, or include appropriate waterproof coatings or membranes to comply with building code requirements.

[0071] In this second example, first wall lining 201 is to be fitted with fittings, which include a sink 401. The sink 401 may be fitted with a faucet, mixer, and/or taps, and a waste water trap, which are not shown for clarity. Alternatively, a mixer for water to the sink may be mounted elsewhere on first wall lining 201.

[0072] For the sink to function, pipes carrying hot and cold water need to extend from the floor or ceiling to the sink, and a waste water pipe needs to extend from the sink to the floor. For the prior art models of cavity slider door, this would be impossible, because there is insufficient space within the wall cavity to allow pipes to run. However, the system of the present invention provides a space 214. A series of plumbing support rails 306, made of timber or a similar material, can be installed within the space 214.

[0073] As shown in FIGS. 2 and 5, in this example, sink inlet pipes 402 can run through the space 214 to inlet ports on the sink 401, and waste water pipe 403 can run through the space 214 from the outlet for the sink 401 to the floor, supported if necessary by connection to one or more plumbing support rails 306.

[0074] Sink 401 can be connected by conventional securing means such as screws through first wall lining 201 to engage with one or more (two in this example) plumbing support rails 306.

[0075] In this way, the cavity slider system of the present invention permits the installation of fittings for a sink or vanity unit on the same wall cavity which houses the door panel in the open position. This provides a useful new option for designers and architects, which was not to possible using the prior art systems.

[0076] Third Example—Device Installation

[0077] A third example of the use of the cavity slider system according to the present invention is for a door adjacent a wall on which a mounted device is to be installed. This example is not shown in the drawings.

[0078] In this example, the first wall lining may be a known type of wall lining, fitted with mounting means such as a bracket to support a display screen or television.

[0079] For the device to function, wires carrying electrical power, and communications signals (such as co-axial, Ethernet or fibre-optic cables) need to extend from the ceiling space (or from the floor space) to the device. It is aesthetically desirable to have these travel through the wall cavity to face plates that are mounted as close as possible to the device, preferably behind where the device will be mounted. For the prior art models of cavity slider door, this would be impossible, because there is insufficient space within the wall cavity. However, the system of the present invention provides a space through which wires can be run. There is also room for the space to include one or more support rails to which the wires can be connected, to keep them neat and easy to locate.

[0080] In this way, the cavity slider system of the present invention permits the installation of a device on the same wall cavity which houses the door panel in the open position. This provides a useful new option for designers and architects, which was not possible using the prior art systems.

[0081] Fourth Example—Heating and/or Cooling Appliance Installation

[0082] A fourth example of the use of the cavity slider system according to the present invention is for a door adjacent a wall on which a heating or cooling appliance is to be installed. This example is not shown in the drawings.

[0083] In this example, the first wall lining may be a known type of wall lining, fitted with mounting means such as a bracket to support a heating and/or cooling appliance. This may be an indoor unit for a heat pump.

[0084] For the appliance to function, wires carrying electrical power need to extend from the ceiling space (or from the floor space) to the appliance. In the case where the heating appliance is part of a heat pump system or central heating system, pipes for carrying air or water to or from the appliance may also be needed, and it may be necessary to install features such as condensers or pumps near the appliance. For the prior art models of cavity slider door, this would be impossible, because there is insufficient space within the wall cavity. However, the system of the present invention provides a space through which wires and/or pipes can be run. There is also room for the space to include one or more support rails to which the wires and pipes can be connected, and which can support the installation of accessory units within the wall cavity.

[0085] In this way, the cavity slider system of the present invention permits the installation of a heating and/or cooling appliance on the same wall cavity which houses the door panel in the open position. This provides a useful new option for designers and architects, which was not possible using the prior art systems.

[0086] The embodiments shown and described in detail herein are by way of example only. The present invention is intended to include such modifications and variations thereto as may be obvious to one skilled in the art.
