Description

29 08 24 Technical Field The present disclosure relates to an adjustable leg for example for a cabinet, and is 5 particularly, although not exclusively, concerned with an adjustable leg comprising a hexagonal foot and a hexagonal attachment portion. Background Legs having adjustable lengths are often provided on items of furniture in order to correct 10 for uneven floors. For example, kitchen cabinets often include four independently adjustable legs in order to allow the cabinet to sit level on an uneven floor. During installation of an item of furniture, fine adjustment of the leg lengths may take place after the item of furniture has been placed on its legs on the floor. This means that the legs will bear the weight of the item of furniture during fine adjustment, and that the legs may be 15 less accessible due to the space restriction imposed by the item of furniture, thus making adjustment more challenging. Statements of Invention The present inventors have determined that certain solutions to the above problems may 20 involve an adjustable leg that may be adjusted from within the item of furniture, such as through the base of a kitchen cabinet. However, such a solution requires the presence of a hole through the base of the kitchen cabinet which mars the appearance of the cabinet throughout its life. It would therefore be advantageous to improve the ease of adjustment of a leg length. It 25 would also be desirable to achieve such an improvement without disrupting the inside surface(s) of the kitchen cabinet. It would be further desirable to provide an alternative means for adjusting a leg length. An adjustable leg for a cabinet is defined by claim 1. The leg comprises: a top section 30 attachable to the cabinet and a base section configured to support the leg on a floor, wherein the base section is configured to threadedly engage the top section such that relative rotation therebetween about a longitudinal axis of the leg varies a length of the 29 08 24 leg, wherein the base section comprises a foot configured to support the leg on the floor, wherein the foot is provided with at least one flat (e.g. a first flat) configured to be engaged by a spanner for rotating the base section relative to the top section. For example, the foot may be engaged by a spanner in situ. The base section may be 5 configured to be threadedly coupled to the top section. The top section comprises an attachment portion configured to attach the top portion of the leg to the cabinet. The attachment portion may have a substantially hexagonal transverse cross section. 10 The foot may comprise a cross section comprising a circle from which a segment has been removed. The foot may comprise a second flat on a side opposing the first flat. The foot may comprise a hexagonal transverse cross section. The foot may comprise a square or octagonal transverse cross section. The foot may be configured to be rotated 15 by a spanner. The foot may comprise a uniform transverse cross section such that an end surface of the foot configured to support the leg on the floor may comprise substantially the same transverse cross section. The first flat, and optionally the second flat, of the foot may 20 intersect the end surface of the foot. The end surface may comprise a hexagonal shape. The attachment portion may comprise an attachment surface configured to abut a lower surface of the cabinet, wherein the attachment surface may comprise a hexagonal shape. The attachment surface may attach to the cabinet in an attachment plane, provided 25 substantially perpendicular to the longitudinal axis of the leg. The attachment surface may be configured to attach directly to the cabinet. The attachment portion comprises a locating protrusion configured to be received in a pre-drilled recess provided in a lower surface of the cabinet. The attachment portion may 30 comprise a locating tab protruding laterally from the attachment portion. The attachment portion may comprise a side face configured to abut a plinth (e.g. in a vertical plane). The attachment portion may comprise a plurality of side faces. The attachment portion may comprise six side faces. 35 The base section may comprise a shaft having a thread. The top section may comprise a shaft having a thread. The thread of the base section may correspond to the thread of the 29 08 24 top section. The shaft of the base section may comprise an external thread, and the shaft of the top section may comprise an internal thread. Relative rotation between the base section and the top section may vary a perpendicular distance between an attachment surface of the attachment portion and an end surface of the foot. Clockwise rotation of the 5 base section relative to the longitudinal axis may advance the base section relative to the top section. The base section comprises an abutment portion having a substantially continuous cylindrical surface configured to abut (e.g. tangentially) a plinth (e.g. in a vertical plane). A 10 radius of the abutment portion (e.g. a distance from a longitudinal axis of the leg to the continuous surface) may be equal to half of the edge-to-edge dimension (e.g. equal to a distance from a longitudinal axis of the leg to a side face) of the hexagonal attachment portion of the top section. The continuous surface of the abutment portion and a side face of the top section are configured to abut a plinth simultaneously (e.g. in a plane parallel to 15 the longitudinal axis of the leg). An adjustable leg assembly is defined by claim 19. The plinth clip may be configured to hold the plinth in a plane in parallel with the longitudinal axis of the adjustable leg. The plinth clip may comprise a jaw element configured to engage a shaft of the top section. 20 A cabinet assembly is defined by claim 22. A method of adjusting an adjustable leg is defined by claim 24. The method may further comprise engaging opposing sides of the foot with a tool; and / or rotating the base section 25 of the leg. To avoid unnecessary duplication of effort and repetition of text in the specification, certain features are described in relation to only one or several aspects or embodiments of the invention. However, it is to be understood that, where it is technically possible, features 30 described in relation to any aspect or embodiment of the invention may also be used with any other aspect or embodiment of the invention. 29 08 24 Brief Description of Drawings For a better understanding of the present invention, and to show more clearly how it may be carried into effect, reference will now be made, by way of example, to the accompanying drawings, in which: 5 Fig. 1A is a top perspective view of an adjustable leg according to one embodiment of the present invention; Fig. 1B is a bottom perspective view of an adjustable leg according to one embodiment of the present invention; Fig. 2A is a side view of an adjustable leg in a shortened configuration according to one 10 embodiment of the present invention; Fig. 2B is a side view of an adjustable leg in a lengthened configuration according to one embodiment of the present invention; Fig. 3A is a bottom perspective view of a plinth clip according to one embodiment of the present invention; 15 Fig. 3B is a bottom perspective view of a fixing bracket for a plinth clip according to one embodiment of the present invention; Fig. 4 is a bottom perspective view of a kitchen cabinet comprising an adjustable leg according to one embodiment of the present invention; and Fig. 5 is a method of adjusting an adjustable leg according to an embodiment of the 20 present invention. Detailed Description Whilst the adjustable leg of the present disclosure will be explained in the context of an adjustable leg for a kitchen cabinet, it will be understood by the skilled person that the 25 adjustable leg may be equally suitable for other items of furniture. With reference to Fig. 1A and Fig. 1B, collectively Fig. 1, an adjustable leg 1 comprises a top section 100 and a base section 200. The top section 100 is configured to attach to an item of furniture, such as a kitchen cabinet 7 (Fig. 4), whilst the base section is configured to support the adjustable leg on a floor or other surface. 30 29 08 24 Top section The top section 100 may comprise a shaft 110 and an attachment portion 120. The shaft 110 may extend away from the attachment portion 120 along a longitudinal axis L-L, and may have a substantially uniform circular cross section. The shaft 110 may be hollow and 5 on an internal circumferential surface may comprise an internal thread 112. One end of the shaft 110 may be open, such that the shaft 110 may comprise a mouth 114. The attachment portion 120 may be substantially planar and may be provided at an end of the shaft 110 opposite to that of the mouth 114. For example, the attachment portion 120 may abut and adjoin an end of the shaft 110 such that the end of the shaft is effectively 10 closed. The attachment portion 120 may extend substantially perpendicularly to the longitudinal axis L-L of the shaft 110 such that the attachment portion 120 occupies a plane substantially transverse to the longitudinal axis L-L of the shaft 110. For example, the attachment portion 120 may form a flange of the shaft 110. The attachment portion may comprise an attachment surface 122 configured to attach the 15 top section 100 of the adjustable leg 1 to a kitchen cabinet 7. For example, the attachment surface 122 may be configured to abut a lower surface 702 (Fig. 4) of the kitchen cabinet 7. The attachment portion 120 may comprise a locating protrusion 124. The locating protrusion 124 may protrude perpendicularly from the attachment surface 122 (e.g. in 20 parallel with, and / or collinear with, the longitudinal axis L-l of the shaft 110) in order to help locate the top section 100 in a desired location of the kitchen unit. For example, the lower surface of the kitchen cabinet may comprise a pre-drilled recess (not shown), within which the locating protrusion 124 may be configured to be received. As shown in Fig. 1, the attachment portion 120 may comprise an hexagonal transverse 25 cross section. For example, the attachment surface 122 may be substantially hexagonal in shape such that it may comprise six edges 123. In other words, the attachment surface 122 may comprise six corners or vertices. The hexagonal transverse cross section of the attachment portion 120 may be concentric with the longitudinal axis L-L of the shaft 110. Each edge 123 of the attachment surface 122 may form part of a longitudinally extending 30 side face 130 of the attachment portion 120. The attachment portion 120 may thereby comprise six side faces 130 disposed substantially in parallel with the longitudinal axis L-L of the shaft 110 but spaced radially or laterally apart therefrom. The vertices between the side faces 130 may be rounded. 29 08 24 Upon attachment of the top section 100 to a lower surface 702 of a kitchen cabinet, the side face 130 may be configured to form a contiguous surface with a lateral and / or front surface of the kitchen unit 702, such that the side face 130 does not protrude beyond the kitchen unit 7. In other words, the side face 130 may sit flush with a surface of the kitchen unit 7. 5 Each side face 130 may be configured to abut a plinth or kickboard of a kitchen cabinet assembly. The attachment portion 120 may comprise a number of (e.g. three) apertures 126 extending longitudinally therethrough. The apertures 126 may be provided at regular spacings across the attachment surface 122. For example, in the embodiment shown in Fig. 1, the apertures 10 may be provided 120 degrees apart. Each aperture 126 may be configured to receive a fastener (e.g a screw) in order to fasten the top section 100 of the adjustable leg 1 to the kitchen cabinet 7 (e.g. a lower surface 702 thereof). For example, with respect to the orientation shown in Fig. 1, a screw may be passed upwards through the attachment portion 120 and screwed in to the lower surface 702 of the kitchen cabinet 7. 15 A number of supporting struts (e.g. webs) may be provided in order to reinforce the coupling between the attachment portion 120 and the shaft 110. The supporting struts may additionally strengthen the top section 100 of the leg 1 in order to increase the loadbearing capacity and stiffness of the leg 1. The attachment portion 120 is thereby rigidly coupled to the shaft 110, such that upon attachment of the attachment portion 120 to the kitchen 20 cabinet 7, the top section 100, including the shaft 110, is rigidly attached to the kitchen cabinet 7. The attachment portion 120 may additionally comprise a locating tab 140. The locating tab may be provided adjacent and substantially coplanar with the attachment surface 122, such that the attachment surface and the locating tab may be contiguous. The locating tab 140 25 may protrude laterally from a corner or edge 123 of the attachment portion 120 in order to aid location of the top section 100 relative to a desired location on a kitchen cabinet. As will be explained below, the outer surface of the shaft 110 may be configured to engage a plinth clip 3 (Fig. 3A). The hexagonal transverse cross section of the attachment portion 120 may allow the 30 kitchen cabinet to be more stable than an equivalent circular attachment portion. For example, the dimensions (e.g. area of attachment surface 122) of an attachment portion 120 having a hexagonal transverse cross section may exceed those of a corresponding attachment portion having a circular cross section. The radial or lateral dimension of the attachment portion may be limited by the distance from the longitudinal axis L-L of the leg 35 to the face at which it abuts the plinth and / or sits flush with the front face of the kitchen unit 29 08 24 7. A circle necessarily has the same radius throughout, whereas a hexagon has a greater dimension from its centre to a vertex than from its centre to a mid-point of a side. The present inventors have thereby determined that an attachment portion of the present invention may thereby be advantageous. 5 Base section The base section 200 may comprise a shaft 210 and a foot 220. The shaft 210 may extend along the longitudinal axis L-L and may have a substantially uniform circular cross section. The shaft 210 may be hollow. On an external surface of the shaft 210, the shaft 210 may comprise an external thread 212. The external diameter of the shaft 210 may correspond 10 with the internal diameter of the shaft 110. For example, the external thread 212 may correspond to the internal thread 112 of the shaft 110 such that the base section 200 may be threadedly engageable (e.g. threadedly couplable) to the shaft 110 of the top section 100 by means of the internal thread 112 and external thread 212. The foot 220 may be provided at the opposite end of the base section 200 to the shaft 210. 15 The foot 220 may extend longitudinally and may be substantially collinear with the shaft 210. The foot 220 and the shaft 210 may extend along the longitudinal axis L-L. The foot 220 may comprise a lateral dimension (e.g. width or diameter) similar (e.g. the same as) the external diameter of the shaft 210 such that the foot 220 and the shaft 210 may appear continuous and / or contiguous. 20 The foot 220 may comprise a substantially hexagonal cross section. In particular, the foot 220 may comprise an hexagonal cross section in a plane transverse to the longitudinal axis L-L of the foot 220. The foot 220 may comprise a substantially uniform hexagonal cross section throughout its length. Accordingly, the foot 220 may comprise six angular side faces or flats 224. The angular side faces 224 may be engageable (e.g. laterally engageable) by 25 a tool, such as a spanner, in order to rotate the base section 200 about its longitudinal axis L-L. The foot 220 may comprise a planar end surface 222. The end surface 222 may be provided at an end of the base section 200 opposite to that of the shaft 210. The end surface 222 may be substantially transverse to the longitudinal axis L-L of the shaft 210 and the foot 30   220. The end surface 222 may be configured to support the base section 200 on a floor or other surface, such that the longitudinal axis L-L of the foot 220 and the shaft 210 may be substantially perpendicular to the floor on which the base section 200 is supported. For example, when the end surface 222 is placed on a horizontal floor, the longitudinal axis L-L of the shaft 210 and the foot 220 may be substantially vertical. 29 08 24 As shown in Fig. 1B, the end surface 222 may be substantially hexagonal in shape. For example, the end surface 222 may comprise six edges 223 in a hexagonal shape. In other words, the end surface 222 may comprise six corners or vertices. The edges 223 and / or vertices of the end surface 222 may comprise a chamfer, bevel and / or rounding. 5 The hexagonal transverse cross section of the foot 220 may be substantially smaller in width than the hexagonal transverse cross section of the attachment portion 120. For example, the hexagonal transverse cross section of the attachment portion 120 may be 75 mm in width (e.g. measured from one opposing side to the other), whilst the foot 220, including the end surface 222, may be approximately half as wide (e.g. 33 mm wide). In 10 other words, the attachment portion 120 may be twice as wide as the foot 220. Similarly, the attachment surface 122 may be twice as wide as the end surface 122. The base section 200 may additionally comprise an abutment portion 230. The abutment portion 230 may be provided part way along the longitudinal axis L-L of the foot 220. The abutment portion 230 may comprise a support flange 234 extending away from the foot 220 15 perpendicular to the longitudinal axis L-L of the foot 220. The abutment portion 230 may additionally comprise a substantially continuous surface 232 connected the support flange. The surface 232 may extend longitudinally in parallel with the longitudinal axis L-L of the foot 220 and the shaft 210 with a circular cross section. The surface 232 may be cylindrical in shape, such that it may be concentric with the longitudinal axis L-L of the foot 220 and 20 spaced apart therefrom. The surface 232 may be configured to abut a plinth or kickboard provided beneath the kitchen cabinet 7 in order to conceal the legs 1 and the space beneath the kitchen cabinet. For example, the surface 232 may tangentially abut a plinth. Due to the cylindrical nature of the abutment portion 230, the surface 232 may comprise rotational symmetry and / or rotational invariance about the longitudinal axis L-L of the foot 220. 25 Assembly During assembly of the adjustable leg 1, the shaft 210 of the base section 200 may be aligned with the shaft 110 of the top section 100. For example, the base section 200 and the top section 100 may be aligned such that their respective longitudinal axes are collinear. The end of the shaft 210 may then be inserted into the mouth 114 of the shaft 110, and the 30 base section 200 rotated relative to the top section 100. For example, the base section 200 may be rotated clockwise relative to the top section 100. The shafts 110, 210 may then threadedly engage one another by means of the internal and external threads 112, 212 such that the base section 200 and the top section 100 become threadedly coupled. Accordingly, relative rotation between the base section 200 and the top section 100 may 35 vary the length of the adjustable leg 1. In particular, relative rotation between the base 29 08 24 section 200 and the top section 100 may vary a distance between the end surface 222 of the foot 220 and the attachment surface 122 of the attachment portion 120. Accordingly, a clearance between a kitchen cabinet supported by the attachment surface 122 and a floor on which the end surface 222 supports the leg 1 may be selectively varied by rotation of 5 the base section 200 relative to the top section 100. For example, clockwise rotation of the base section 200 relative to the top section 100 may shorten the length of the leg 1 by advancing the shaft 210 within the shaft 110. Conversely, anti-clockwise rotation of the base section 200 relative to the leg 100 may lengthen the leg 1 by causing the shaft 210 to back out of the shaft 110. 10 Figs. 2A and 2B, collectively Fig. 2, show the leg 1 in which the base section 200 has threadedly engaged, and become threadedly coupled to, the top section 100. Fig. 2A shows the leg 1 adjusted to its maximum length. The maximum length of the leg (e.g. the maximum perpendicular distance between the abutment surface 122 and the end surface 222) may be approximately (e.g. equal to) 200 mm. Fig. 2B shows the leg adjusted to near its 15 minimum length. The minimum length of the leg 1 (e.g. the minimum perpendicular distance between the abutment surface 122 and the end surface 222) may be approximately (e.g. equal to) 140 mm. The side 130 and the continuous surface 232 may be vertically aligned, such that they may be disposed an equal distance from the longitudinal axis L-L of the assembled leg 1. The 20 side 130 and the continuous surface 232 may thereby be configured to simultaneously abut a surface of a plinth, which the leg 1 is configured to support, in a substantially vertical plane. Plinth Clip With reference to Fig. 3A, a plinth clip 3 may comprise a jaw element 300 and a slide 25 element 320. The jaw element 300 may comprise an incomplete circular shape. For example, the jaw element 300 may comprise an arc spanning approximately 270 degrees and an opening 310 spanning approximately 90 degrees. The jaw element 300 may thereby comprise a C-shape. The plinth clip 3 may be made from an elastically deformable material (e.g. polypropylene) such that the opening 310 of the jaw element 300 may be able to widen 30 and spring back. The opening 310 may be defined by a pair of lips 312, each lip 312 protruding radially from a distal point of the arc. The jaw element 300 and the opening 310 may be comprise an internal dimension (e.g. internal diameter) such that the plinth clip 3 may be able to receive and / or engage (e.g. grip on to) the shaft 110 of the top section 100 of the adjustable leg 1. 29 08 24 For example, the opening 310 may be marginally narrower than the diameter of the shaft 110, such that a threshold force is required to push the shaft 110 through the opening 310 and into the jaws 300. The jaws 300 may subsequently grip the shaft 110 such that the plinth clip 3 is secured thereto. For example, upon application of a threshold force, the plinth 5 clip 3 may be translatable linearly along a portion of the length of the shaft 110, in order to accommodate different leg lengths. At a side of the jaw element 300 opposite to that of the opening 310, the jaw element 300 may be attached to the slide element 320 by means of a bridge element 322. The slide element 320 may be substantially planar, with the bridge element 322 extending 10 perpendicularly therefrom at a central point. Accordingly, the slide element 320 may comprise a flat, planar border along its edges. With reference to Fig. 3B, a fixing bracket 5 may comprise a channel 520 and apertures 510 for receiving fasteners (not shown). The fixing bracket 5 may be substantially planar, such that its rear surface (not shown) may be flat. The fixing bracket 5 may be configured 15 to be fastened flush to a surface of a plinth or kickboard of a kitchen cabinet 7. In particular, the fixing bracket 5 may be configured to be screwed into a plinth using the apertures 5, such that the rear surface of the fixing bracket 5 may sit flush on a surface of the plinth. The channel 520 may be configured to receive the slide element 320 of the plinth clip 3. For example, the channel 520 may be configured to slidingly receive the slide portion 320 20 of the plinth clip, such that the plinth clip 3 and the fixing bracket 5 may be coupled to one another. The plinth clip 3 and the fixing bracket 5 may thereby be slidably attachable and detachable. In the attached configuration (not shown), the slide element 320 of the plinth clip 3 may be located within the channel 520, the bridge element 322 protruding perpendicularly therefrom and connecting the kickboard to the adjustable leg 1 via the jaw 25 element 300. The top section 100, the base section 200, the plinth clip 3 and / or the fixing bracket 5 may be injection moulded. The plinth clip 3 and the fixing bracket 5 may be injection moulded as one piece with a pre-defined break-point in order to separate the two parts. The top section 100, the base section 200, the plinth clip 3 and / or the fixing bracket 5 may be made from 30 polypropylene. Installation During installation, the top section 100 may be attached to an item of furniture such as a kitchen cabinet 7. In particular, the top section 100 may be attached to a lower (e.g. lowermost) surface 702 (e.g. a base) of a kitchen cabinet 7 at a particular location, as 29 08 24 defined and located by a pre-drilled recess corresponding to the locating protrusion 124 and / or the locating tab 140. Fasteners may be inserted through the apertures 126 and into the lower surface 702 of the kitchen unit 7, such that the top section 100 becomes rigidly fixed thereto. 5 The shaft 210 of the base section 200 may threadedly engage the shaft 110 of the top section 100. The shafts 110, 210 of the top and base sections 100, 200 may be aligned along the longitudinal axis L-L the shaft 110 being inserted into the mouth 114 of the shaft 210, and the base section 100 being rotated clockwise relative to the top section 100 and / or the kitchen cabinet 7. 10 Three further legs 1 may be attached to the lower surface 702 of the kitchen cabinet in a similar manner. The legs 1 may be adjusted to a uniform height (e.g. 170 mm) such that each leg may be subsequently either lengthened or shortened. The kitchen cabinet may be placed on the floor, and the level of the kitchen unit determined (e.g. using a spirit level). During fine adjustment of the level of the kitchen unit, an installer may use a spanner or 15 other tool (e.g. adjustable wrench) to rotate the base section of one or more legs 1 either clockwise or anticlockwise in order to shorten or lengthen respectively the leg 1. The installer may thereby finely adjust the level of the kitchen cabinet without requiring access to the inside of the kitchen cabinet, and / or without requiring a hole through the base of the kitchen cabinet. 20 Upon completion of the fine adjustment of the leg lengths, a number of fixing brackets 5 may be attached to a plinth by means of fasteners such as screws. A plinth clip 3 may be slidably coupled to each fixing bracket 5 by means of slide element 320 and channel 520. The openings 310 of the plinth clips may then be pushed against the shaft 110 of each of a corresponding number of legs 1, the plinth clip 3 then “snap fitting” onto the shaft 110 so 25 as to hold the plinth vertically against the continuous surface 232 and a side face 130. Method of adjusting With reference to Fig. 5, there is provided a method 500 of adjusting a length of a leg 1. The method 500 may comprise 502 providing an adjustable leg 1. The method 500 may comprise 504 engaging opposing sides 224 of the foot 220 with a tool (not shown). The 30 method 500 may comprise 504 rotating the base section 200 of the leg 1 using the tool so as to adjust a length of the leg 1. Additional statements of invention are set out below: Statement 1.
