Description
ORIGINAL AUSTRALIA Patents Act 1990 COMPLETE SPECIFICATION Standard Patent Invention title: "PARTITION WALL SUPPORT LEG" Applicant: Rynat Australia Pty Ltd The following statement is a full description of this invention, including the best method of performing it known to me: -2 "PARTITION WALL SUPPORT LEG" Field of the Invention The present invention relates to a support leg for supporting a partition wall and relates particularly, though not exclusively, to a support leg for a toilet cubicle in 5 a public bathroom or change-room. Background to the Invention Public bathrooms typically have separate cubicles for each toilet or shower recess, separated from adjoining cubicles by partition walls. The partition walls do not normally extend from floor to ceiling but instead are supported above 10 floor level on a plurality of support legs. This makes it easier to clean the floors and reduces the number of corners and skirtings where grime can accumulate. It also helps to improve security as it is possible to see which cubicles are occupied by looking under the partition walls and doors. Prior art support legs for the partition walls typically comprise a threaded shank 15 with a foot at the bottom end, and which screws into a tubular support fixed to the lower edge of the partition wall. The height of the support leg can be adjusted by screwing the threaded shank up or down as the floor level requires. A problem with this arrangement is that the threaded shank is exposed and often accumulates grime and threads from the cleaner's mop which get caught 20 on the thread. The shanks quickly corrode and become unsightly, not to mention unhygienic, due to the accumulation of grime and other matter. The present invention was developed with a view to providing a support leg for partition walls which has a more aesthetically pleasing finish and is therefore more visually attractive in use. Although the preferred embodiment is described 25 in relation to partition walls for bathroom cubicles, it will be understood that the invention has wider application wherever a partition wall is required to be supported above floor level. References to prior art in this specification are provided for illustrative purposes only and are not to be taken as an admission that such prior art is part of the 30 common general knowledge in Australia or elsewhere.
-3 Summary of the Invention According to one aspect of the present invention there is provided a support leg for supporting a partition wall, the leg comprising: an elongate support tube having a top end and a bottom end; 5 an adjustable top cap adapted to be mechanically coupled to the top end of the support tube by an internal screw-thread connection, wherein the height of the top cap relative to the support leg can be adjusted by turning the support tube to cause the top cap to move up or down, the top cap having a recess adapted to receive a lower edge of a partition wall therein, and wherein the top cap 10 further comprises a skirt having an internal diameter slightly larger than the external diameter of the support tube, the skirt being received in use over the top end of the support tube so as to hide the top end from view; and, a foot designed to engage with the bottom end of the support tube and having fastening means for fixing the bottom end of the support tube to a floor. 15 In a preferred embodiment the elongate support tube has a threaded hole provided in the top end, and the top cap has a threaded connecting rod provided on its underside which is received in the threaded hole to form said internal screw-thread connection. Preferably the support tube and top cap are of substantially circular cross-section. 20 Advantageously the recess provided on the top cap is an adjustable fixing recess having a generally horizontal ledge on which the lower edge of the partition wall is supported, and a vertical surface against which a side surface of the lower edge of the partition wall can be fixed using a suitable fastening arrangement. Typically a threaded aperture is provided in the vertical surface of 25 the top cap for receiving a security bolt that passes through the partition wall adjacent a lower edge to fix it to the top cap. The adjustable fixing recess may further comprise a spacer element received between a head of the security bolt and the side surface of the lower edge of the partition wall. The spacer element is typically provided with a rubber liner that sits between the spacer element -4 and the generally horizontal ledge of the adjustable fixing recess and/or the side surface of the lower edge of the partition wall. In a preferred embodiment the bottom end of the support tube is open and the foot comprises a spigot which is received inside the open end of the support 5 tube. Preferably the spigot is provided with a central aperture through which a first threaded fastener is received for fixing the spigot to the floor. Preferably a second threaded fastener is received in an aperture provided in the wall of the support tube adjacent the bottom end, the second threaded fastener being adapted to engage with the spigot to retain the bottom end of the support tube 10 in connection therewith. Typically the first threaded fastener is a bolt which may be screwed into a hole drilled into the floor using a masonry plug. Typically the second threaded fastener is a grub screw. Throughout the specification, unless the context requires otherwise, the word "comprise" or variations such as "comprises" or "comprising", will be 15 understood to imply the inclusion of a stated integer or group of integers but not the exclusion of any other integer or group of integers. Likewise the word "preferably" or variations such as "preferred", will be understood to imply that a stated integer or group of integers is desirable but not essential to the working of the invention. 20 Brief Description of the Drawings The nature of the invention will be better understood from the following detailed description of several specific embodiments of the support leg of the invention, given by way of example only, with reference to the accompanying drawings, in which: 25 Figure 1 is a back isometric view of a preferred embodiment of a support leg for a partition wall according to the present invention; Figure 2 is a front isometric view of the support leg of Figure 1; Figure 3a is a top plan view of the support leg of Figure 1; Figure 3b is a side elevation view of the support leg of Figure 1; -5 Figure 3c is a bottom plan view of the support leg of Figure 1; Figure 4 is a back elevation view of the support leg of Figure 1; Figure 5 is a back isometric view of the support leg of Figure 1 supporting a partition wall in use, absent the spacer element; 5 Figure 6 is a front isometric view of the support leg as shown in use in Figure 5; Figure 7 is an exploded view of the support leg of Figure 1 and a bottom edge of a partition wall; Figure 8a is a back isometric view of the support leg, similar to Figure 1 10 but with a fixing bolt and masonry plug attached; Figure 8b is a front isometric view of the support leg of Figure 8a; Figure 8c is an exploded view of the support leg of Figure 8a; Figure 9a is a front elevation view of the support leg of Figure 8a showing hidden lines in dotted outline; 15 Figure 9b is a vertical cross-section view of the support leg through the line A-A in Figure 9a; Figure 9c is a top plan view of the support leg of Figure 9a showing hidden lines in dotted outline; Figure 10a is a top plan view of a support tube of the preferred 20 embodiment of the support leg illustrated in the foregoing drawings; Figure 10b is a front elevation view of the support tube of Figure 10a showing hidden lines in dotted outline; Figure 10c is a vertical cross-section view of the support tube through the line B-B in Figure 10b; 25 Figure 1Od is an isometric view of the support tube of Figure 10a; -6 Figure 11 a is front elevation view of a top cap employed in the preferred embodiment of the support leg illustrated in the foregoing drawings showing hidden lines in dotted outline; Figure 11 b is a top plan view of the top cap of Figure 11 a; 5 Figure 11c illustrates a possible manufacturing process for the top cap of Figure 11a; Figure 1ld is a vertical cross-section view of the top cap through the line A-A in Figure 11a; Figure 11e is a front isometric view of the top cap of Figure 11 a; 10 Figure 1 1f is a back isometric view of the top cap of Figure 11 a; Figure 12a is a front elevation view of a spacer element employed in the preferred embodiment of the support leg illustrated in the foregoing drawings; Figure 12b is top plan view of the spacer element of Figure 12a; 15 Figure 12c is a vertical cross-section view of the spacer element through the line C-C in Figure 12a; Figure 12d is a top plan view of a spigot employed in the preferred embodiment of the support leg illustrated in the foregoing drawings; Figure 12e is a vertical cross-section view of the spigot through the line 20 A-A in Figure 12d; Figure 12f is a back isometric view of the spacer element of Figure 12a; and, Figure 12g is a front isometric view of the spacer element of Figure 12a. Detailed Description of Preferred Embodiments 25 A preferred embodiment of the support leg 10 for a partition wall in accordance with the present invention, as illustrated in the accompanying drawings, comprises an elongate support tube 12 having a top end and a bottom end. An -7 adjustable top cap 14 is adapted to be mechanically coupled to the top end of the support tube 12 by an internal screw-thread connection, as described in more detail below. In use, the height of the top cap 14 relative to the support leg 12 can be adjusted by turning the support leg 12 which causes the top cap 5 14 to move up or down. The top cap 14 has a recess 16 adapted to receive a lower edge 18 of a partition wall therein. The support leg 10 further comprises a foot 20 designed to engage with the bottom end of the support tube 12 and has a fastening means for fixing the bottom end of the support tube 12 to a floor (not shown). 10 In the preferred embodiment, the elongate support tube 12 has a threaded hole 22 provided in the top end, and the top cap 14 has a threaded connecting rod 24 (see Figures 9a, 9b, 11a, 11c and 11d) provided on its underside. The threaded connecting rod 24 is received in the threaded hole 22 to form the internal screw-thread connection. A possible process for fixing the threaded 15 connecting rod 24 to the underside of the top cap 14 is illustrated in Figure 1 1c. The threaded rod 24 is prepared and a threaded hole drilled into the top of top cap 14. The threaded rod 24 is then screwed into the threaded hole and welded into position. The top surface of the threaded rod 24 is then machined or ground flat using an angle grinder. The threaded connecting rod 24 of this 20 embodiment permits the height of the top cap 14 relative to the support tube 12 to be adjusted up or down by up to about 30mm. This gives an overall height of the support leg 10 of between 165 to 195mm. However the threaded hole 22 (with corresponding threaded connecting rod) can of course easily be made longer, typically giving an overall adjustment height of the support leg between 25 about 165 and 230mm. This is compared to a range of about 170-195mm in a prior art support leg. Preferably both the support tube 12 and top cap 14 are of substantially circular cross-section and are manufactured from stainless steel or aluminium. The top cap 14 preferably further comprises a cylindrical skirt 26 having an internal 30 diameter slightly larger than the external diameter of the support tube 12. In use the skirt 26 is received over the top end of the support tube 12 so as to hide the top end and the threaded connecting rod 24 from view. Thus an -8 aesthetically pleasing finish is achieved and a visually attractive appearance is maintained at all times. Furthermore, the accumulation of grime or the catching of threads from the cleaner's mop on the support leg 10 is substantially inhibited. 5 Advantageously the recess 16 provided on the top cap 14 is an adjustable fixing recess having a generally horizontal ledge 28 on which the lower edge 18 of the partition wall is supported (see Figures 7 and 1 1f). The adjustable fixing recess 16 further comprises a vertical surface 30 against which a side surface of the lower edge 18 of the partition wall can be fixed using a suitable fastening 10 arrangement. Typically a threaded aperture 32 is provided in the vertical surface 30 of the top cap 14 for receiving a security bolt 34 that passes through the lower edge 18 of the partition wall to fix it to the top cap 14. The adjustable fixing recess 16 may further comprise a spacer element 36 received between a head of the security bolt 34 and the side surface of the 15 lower edge 18 of the partition wall (see Figures 1, 3, 4, 7, 9b, 12a, 12b, 12c, 12f and 12g). An aperture 38 provided in the spacer element 36 receives the security bolt 34 there through. Preferably the spacer element 36 is provided with a rubber liner (not visible) that sits between the spacer element 36 and the generally horizontal ledge 28 of the adjustable fixing recess 16 and/or the side 20 surface of the lower edge 18 of the partition wall. The rubber liner improves the friction between the adjoining surfaces and inhibits relative movement. The illustrated embodiment of the support leg 10 is designed specifically for supporting partition walls manufactured from either medium density fibre (MDF) board or 13mm solid compact laminate boards. Either board type of various 25 thicknesses can be accommodated in the recess 16 of the top cap 14. For example the lower edge 18 of a partition wall made from 18mm thick MDF board can be secured directly onto the top cap 14 by means of a security bolt 34 that passes through a suitable aperture, as shown in Figures 5 and 6. In this case no spacer element 36 is required. On the other hand, if the partition wall is 30 made from a thinner board substrate, say 13mm thick, the spacer element 36 can be used together with a security bolt 34 to secure the lower edge 18 of the board to the vertical surface 30 of the adjustable fixing recess 16, as shown in -9 Figure 7. The upper edges of both the top cap 14 and the spacer element 36 have a bevelled surface to provide an aesthetically pleasing finish. In the illustrated embodiment the bottom end of the support tube 12 is open (see Figure 1 Oc) and the foot 20 comprises a spigot 40 which is received inside 5 the open end of the support tube 12 (see Figures 7, 9a and 9b). Preferably the spigot 40 is provided with a central aperture 42 (see Figures 12d and 12e) through which a first threaded fastener 44 is received for fixing the spigot to the floor. The spigot 40 is of cylindrical configuration having an outside diameter slightly smaller than the internal diameter of the support tube 12. Preferably a 10 second threaded fastener 46 is received in an aperture 48 provided in the wall of the support tube 12 adjacent the bottom end of the support tube. The second threaded fastener 46 is adapted to engage with the spigot 40 in use to retain the bottom end of the support tube 12 in connection therewith. The spigot may be made of metal or plastic, and of a larger diameter than that shown in the 15 drawings. When the spigot is made of a larger diameter than that shown in the drawings, this improves the stability of the support leg, and restricts movement of the support tube. Typically the first threaded fastener is a bolt 44 which may be screwed into a hole drilled into the floor (not shown) using a masonry plug 50. Preferably the 20 second threaded fastener is a grub screw 46. When installing the partition wall, a hole is drilled into the (concrete or tiled) floor of the bathroom in the desired position of the support leg 10. The masonry plug is then inserted and forced into the hole in the floor with a hammer. The spigot 40 can then be fixed to the floor by screwing the bolt 44 through the central aperture 42 into the masonry 25 plug 50. The open end of the bottom of the support tube 12 is then placed over the spigot, and the grub screw 46 provided in aperture 48 is tightened until it engages the outer circumference of the spigot 40. The outer circumference of the spigot 40 may be provided with an annular recess, as can be seen most clearly in Figure 9b. When the inner end of the grub screw 46 is received in the 30 annular recess of the spigot 40, the bottom end of the support tube 12 is effectively locked onto the spigot 40 and secured into position on the floor.
-10 Now that preferred embodiments of the support leg 10 have been described in detail, it will be apparent that the embodiments provide a number of advantages over the prior art, including the following: (i) The support leg has a more aesthetically pleasing finish and is 5 therefore more visually attractive in use. (ii) The screw thread connection between the top cap 14 and the support tube 12 is fully enclosed and not visible from the exterior, so that it is less likely to accumulate grime or catch threads from a cleaner's mop. 10 (iii) The screw thread connection provided by the threaded connecting rod 24 in threaded hole 22 permits an overall improved height adjustment of varying ranges, which can typically be in the range of between 170 to 230mm. 15 It will be readily apparent to persons skilled in the relevant arts that various modifications and improvements may be made to the foregoing embodiments, in addition to those already described, without departing from the basic inventive concepts of the present invention. For example, the manner in which the lower edge of the partition wall is secured to the top cap 14 may vary 20 substantially from that described and illustrated. Therefore, it will be appreciated that the scope of the invention is not limited to the specific embodiment described.
