DETAILED DESCRIPTION OF THE INVENTION

(8) Referring firstly to FIG. 1, the invention provides a simple yet effective means of mounting an item of furniture 10 in a cavity 11 exposed by an aperture in a panel or cladding applied to a stud wall, that is to say a wall comprising cladding 12 fixed to spaced vertical studs, one of which is shown in dotted outline at 13. In the well-known manner, the inner face 14 of the cladding engages the studs while the outer face 15 provides the visible wall surface. In this example the item of furniture 10 comprises a hollow body 16 that locates within the cavity, and spaced contact surfaces 17 that project from the body 16 to overlie parts of outer face 15 of the wall, the contact surfaces 17 serving as a position datum that limits the degree to which the hollow body 16 can be inserted into the cavity 11. As will be described in greater detail below, fixing means 18 are mounted on an exterior of the body 16 in the manner such that they can be displaced relative to the body, from the interior of the body, against the inner face 14 of the cladding. This, in turn, clamps the contact surfaces 17 against the outer cladding face 15.

(9) As used herein the term ‘item of furniture’ should be interpreted in its broadest sense and to include (but not necessarily be restricted to) a cupboard, a cabinet, a shelving unit, and a support for mounting other wall-mounted items. However, for explanatory purposes, the following description is to be directed to the invention when applied to a cabinet intended for mounting within cavity 11.

(10) Turning now to FIGS. 2 to 6, a typical bathroom cabinet 20 is shown, the carcass of which in this case is formed from sheet aluminium although the use of this material is by no means essential. The cabinet 20 includes a back or base 21 from which project top 22, bottom 23 and spaced sides 24 and 25. The combination of back 21, top 22, bottom 23 and sides 24 & 25 define an interior volume 26 and the outer or free edges of the wall components combine to define an opening 27 to the volume 26. An outwardly directed peripheral lip or flange 28 surrounds the opening 27 and a door (not shown) may be fitted into the opening 27. The lip or flange 28 includes and/or defines the position datum.

(11) The cabinet 20 has an insertion axis 29 along which the cabinet is inserted into cavity 11.

(12) In the form shown, mounting slots 30 are provided in sides 24 & 25 of the cabinet that are at least generally aligned in the direction of the insertion axis 29 and, in the particular form shown, are aligned parallel to the insertion axis. In this example at least one slot 30 is required in each of sides 24 & 25 and preferably two are provided, one adjacent to top 22 and one adjacent to bottom 23. Each slot is preferably identical and is defined by a first section 31 and a second section 32, the section 31 merging into the section 32 in the direction of the insertion axis 29 and being of a greater width than the section 32.

(13) The fixing means 18 is configured so that it can be positioned in place and displaced into a locking position entirely from within the interior volume 26 yet those parts that provide the locking action to the inner cladding surface can be hidden from view. As shown in FIG. 3 the fixing means 18 comprises a locking stud 34 and a positioning or locking tab 35 that is fixed to the locking stud 34 by any suitable fastening such as screw 36. The locking tab 35 includes a spigot 37 that engages within bore 38 in the locking stud 34 to lock the stud 34 against rotation relative to the locking tab 35. As can be seen in FIG. 3, locking tab 35 the positions of the screw fixing and the spigot 37 are offset from the centreline 40 of the locking tab, and the diameter of the spigot is a clearance fit within part 32 of the slot 30, allowing the screw and spigot to slide along part 32 of the slot but preventing rotation of the locking tab relative to the slot. To further ensure pure sliding action of the locking tab 35 in part 32 of the slot, a lozenge-shape boss 39 may be formed about the base of spigot 37, the vertical dimension of the boss being a sliding fit in part 32 of the slot. It will be further noted that the locking stud 34 is dimensioned to pass through part 31 of the slot 30. Finally, this particular embodiment of fixing means includes a resilient O-ring 41 that locates in groove 42 on the inner surface of the locking tab 35 to increase the frictional engagement of the locking tab 35 with the cabinet sides 24 & 25.

(14) The fixing means 35 shown in FIG. 3 is shown assembled to the cabinet side 24 in FIGS. 4 & 5, it being appreciated that the assembly of the fixing means to the cabinet side 25 is simply a mirror image of what is shown. When assembled, the locking stud 34 of the fixing means is concealed in the cavity 11, the only part being visible within the cabinet being the locking tab 35. If desired, this can be provided with an aesthetically pleasing cover (not shown).

(15) A sequence of fitting cabinet 20 into a wall cavity is shown in FIGS. 6A to 6F. Firstly, an aperture is created in the wall cladding to expose the cavity in which the cabinet is to be fitted. As with prior art applications the cavity should be sufficiently large to receive the periphery of the cabinet carcass defined by the outer surfaces of top 22, bottom 23 and sides 24 & 25, but sufficiently small to be overlaid by peripheral flange 28. In the event a stud 13 passes through the position selected for the cavity, a part must be removed to allow the cabinet to be inserted. In this event, it is preferred that the upwardly facing edge of the stud section remaining following removal of part of the stud, is horizontal and substantially flush with the bottom edge of the formed aperture so that the stud can add vertical support to the cabinet, once installed. In the absence of a stud, the cabinet may rest substantially on the lower edge of the aperture in the wall cladding.

(16) With the cavity prepared, the cabinet is inserted along insertion axis 29 until the flange 28 contacts the wall cladding surrounding the formed aperture. The locking tab 35 is loosely fitted to the locking stud 34 and the stud then passed through part 31 of the slot 30 to locate within the cavity 11. In FIG. 6A, the offset attachment of the stud 34 to the tab 35 is shown positioned closer to the rear of the cabinet meaning that the fixing means is configured for thicker wall claddings. If the fixing means is to be used with thinner wall claddings, the assembly is rotated as shown in FIG. 6B, while still positioned to the rear of slot 30, so that the offset is now closer to the front of the cabinet. Regardless of the position of the offset, the locking tab 35 is preferably dimensioned so that the slot 30 is covered when the cabinet is locked in place.

(17) With the locking tab and locking stud assembled and positioned within slot 30 such that some friction is generated between the cabinet side and the O-ring 41, the assembly can be displaced forward, in the direction shown by the arrows in FIGS. 4, 5, 6C & 6D until the stud 34 buts up against the inner face of the wall cladding. Thereafter the screw 36 is further tightened to lock the fixing means relative to the cabinet side and thus, in turn, retain the cabinet within the cavity.

(18) Those skilled in the art will appreciate that many variations to the embodiment described could be realised without departing from the scope of the invention. By way of example only, the fixing means could, alternatively or in addition, be fitted to the top 22 and bottom 23 of the cabinet. Further, while the linear sliding action between the fixing means and the cabinet carcass is a simple and convenient way of providing the necessary relative adjustment, alternative relative movements, including cam-based actions, could be employed.

(19) It will thus be appreciated that the invention, at least in the case of the particular embodiment described, provides a simple yet effective method and apparatus that allows persons of limited skill to effectively and accurately mount furniture items in cavities in stud walls while offering more skilled people a method and/or apparatus that can substantially reduce the time required to perform such tasks.
