BACKGROUND ART

Any discussion of background art, any reference to a document and any reference to information that is known, which is contained in this specification, is provided only for the 0 purpose of facilitating an understanding of the background art to the present invention, and is not an acknowledgement or admission that any of that material forms part of the common general knowledge in Australia or any other country as at the priority date of the application in relation to which this 25 specification has been filed.

Normally a drawer for separate waste collection is constituted by a guide installed inside the cabinet compartment wherein the drawer operates, a sliding frame along the guide and 30 adapted to support one or more waste holding buckets, a front door fixed to the frame and a backboard fixed to the frame.

Currently the cabinet, the guide, the door and the backboard is built by the cabinet maker while said frame and buckets are 35 manufactured by a company supplying the cabinet maker. 2 2013213278 20 Apr 2017

The main problems that currently exist lie in the fact that in the same area width wherein the drawer must operate every cabinet maker installs his own guide of construction and size different than those guides installed by other cabinet makers. 5 Consequently, the frame-work manufacturing companies must produce a series of models thereof each suited to the type of guide used by the cabinet maker. In addition, the guide with the current commercially available frames remains visible, and therefore is not only unsightly but subject to collecting dust 0 and occasional particles of waste (because of the use of the drawer). Finally, with the current frame-work there arises the complexity of being able to adjust the width thereof to obtain a precise and effective support for holding the waste buckets.

5 SUMMARY OF INVENTION

According to an aspect of the present invention, there is provided a drawer for separate waste collection to be installed inside a compartment made in a cabinet and delimited by two side walls that support a respective guide along which 0 a frame that supports a plurality of waste holding buckets slides, wherein said frame has a rectangular perimeter development and comprises two lateral elongated side bodies parallel to each other and two bars parallel to each other for connecting together the longitudinal ends of said bodies; each 25 of said bodies having a covering member of the corresponding said guide; wherein said covering member comprises a first tab of substantially the same length as said body and when installed inside said compartment extending in a horizontal plane towards the corresponding said side wall of said 30 compartment; a second tab shaped as an inverted L, of substantially the same length as said first tab and having a first portion defined in a horizontal plane which in use is inserted between said first tab and the top part of said guide and a second portion defined in a vertical plane and that 35 laterally covers the upper part of said guide; the drawer further comprising fastening means between said tabs 3 2013213278 20 Apr 2017 constituted by at least one knurled area defined on the upper face of said first portion and at least one tooth that extends from the lower face of said first tab and which engages with its tip a region of said knurled area; said fastening means 5 between said tabs allowing the position adjustment of said second tab with respect to said first tab so as to adjust the covering area of said guide as a function of the size thereof.

Preferably, on the face of each of said bodies facing the 0 corresponding face of the other said body, at least at one longitudinal end, there extends towards the other said body a corresponding sleeve adapted to house the longitudinal end of the corresponding said bar. 5 Preferably, the drawer further comprises means for adjusting the distance between said bodies.

DESCRIPTION OF EMBODIMENTS

With reference to Figure 1 a drawer for separate waste 5 collection installed inside a compartment 2 made in a cabinet 3 is indicated as a whole; the two side walls 4 bounding the compartment 2 supporting a respective guide 5 (figure 6) . The drawer 1 comprises a frame 6 which supports a plurality of holding waste buckets 7 and which is slidable along the guides 0 5 during opening and closing of the drawer 1.

With reference to Figures 2 to 5, the frame 6 has a rectangular perimeter development and comprises two side elongated bodies 8 parallel to each other and two bars 11 25 parallel to each other for connecting together the ends of the longitudinal bodies 8; the bodies 8 being preferably made of plastic material and the bars 11 being preferably made of metallic material. On the face of each body 8 facing the corresponding face of the other body 8, at both longitudinal 30 ends extends towards the other body 8 a corresponding sleeve 12 internally hollow and having a rectangular inner section. The sleeves 12 housing the longitudinal ends of the bars 11. Moreover, the upper wall of each sleeve 12 has a through slot 13 with longitudinal axis perpendicular to the longitudinal 35 axis of the corresponding body 8. The longitudinal end of each bar 11 has a threaded hole 14 inside the sleeve 12 and exactly 5 2013213278 20 Apr 2017 in correspondence to the slot 13. A corresponding screw 15 creates the fastening between the sleeve 12 and the bar 11 which has its longitudinal end housed inside the sleeve 12. In fact, the threaded shank of the screw 15 passes through the 5 slot 13 and is screwed into the hole 14. Naturally the screw head 15 has a diameter greater than the width of the slot 13. This fastening system just described allows to adjust, before the screwing of the screws 15, the position of the longitudinal ends of the bars 11 inside the respective sleeves 0 12 and then allow to adjust the distance between the bodies 8 also according to the width of the compartment 2.

With reference to Figures 6 and 7, the guide 5 is supported by way of a bracket 16 from the corresponding side wall 4 of the 5 compartment 2. In said figures the solid line illustrates a guide 5 and the dashed lines illustrate other types of guides 5. The parts in common to all these guides 5 are, apart from the connection by way of the bracket 16 to the wall 4, a side projection 17 having a substantially triangular shape that 0 reaches a recess 18 which also has a triangular shape formed on the face of the body 8 facing the guide 5. It is evident that the projection 17-recess 18 coupling constitutes the supporting device and the guide of the drawer 1. Furthermore, as can be seen, the geometric development of various guides 5 25 is different and therefore is important as stated above to achieve a correct and precise adjustment of the distance between the bodies 8.

With reference to Figures 4 to 7, each body 8 has an integral 30 tab 21 of the same length as the body 8 extending in a horizontal plane towards the corresponding wall 4. In addition, to each body 8 is associated a tab 22 shaped as an inverted L and of the same length as the tab 21. The tab 22 has a first portion 23 defined in a horizontal plane which in 35 use is inserted between the tab 21 and the upper part of the guide 5 and a second portion 24 defined in a vertical plane 6 2013213278 20 Apr 2017 and that laterally covers the upper part of the guide 5. In essence, the tab 22 is substantially at the same level of the tab 21 and above all covers the guide 5 carrying out both an aesthetic function and a barrier function against any dust or 5 anything else that comes to rest in the area occupied by the guide 5 with consequent sliding problems of the drawer 1. It should be noted that on the upper face of the portion 23 there are two small areas 25 which are knurled and that from the lower face of the tab 21 exactly in correspondence to said 0 areas 25 downwardly originate teeth 26 engaging with their tips said areas 25 thus actuating the fastening of the tab 22 to the corresponding body 8 as the portion 23 is pressed by the upper part of the guide 5 on the lower face of the tab 21.

This type of fastening as it appears evident also allows 5 adjustment of the position of the tab 22 with respect to the corresponding body 8 by engaging the teeth 26 with a different zone of the areas 25. In this way it is possible to position the tab 22 according to the size of the guide 5. 0 With reference to Figure 1, each body 8 at its front longitudinal end supports a corresponding bracket 31 to which, by means of screws not shown, a door 32 of the drawer 1, shown in dashed lines, is fixed. Similarly each body 8 at its rear longitudinal end supports a respective bracket, not shown, for 25 the fastening of a backboard (not shown) of the drawer 1.

With reference to Figures 1 and 2 the frame 6 has a support area for the buckets 7. This support area is defined by the upper face of the bars 11, by the upper face of a bar 33 30 parallel to the bodies 8 and which connects the centerlines of the bars 11 and by the upper face of a portion 34 which extends from the wall of the body 8 facing the other body 8. The buckets 7 have an upper edge 35 folded towards the outside by way of which each bucket 7 rests on the upper face of the 35 corresponding area of the bars 11, of the bar 33 and of the portion 34. 7 2013213278 20 Apr 2017

From that described above the advantages of the embodiment of the present innovation become evident and numerous. 5 In particular a drawer 1 is obtained which has a cover system of the guides 5 not only easy to assemble but also provided with simple fastening means and with means for adjusting the position of the tab 22 with respect to the tab 21 that allows to obtain a cover adaptable to dimensions of the guide 5 which 0 may be different from cabinet maker to cabinet maker as already mentioned. The cover system, besides an aesthetic function, protects the guides 5 from the collection of dust or anything else that could affect the sliding quality of the drawer 1. Moreover, the drawer 1 has means for fastening the 5 bodies 8 and the bars 11 one to the other that are also means for adjusting the distance between the bodies 8 so as to adapt to the width of the compartment 2 and to the dimensions of the guides 5. It should be noted that the adjustment is made using simple screws 15 screwed from above and overall without 0 disassembling the various parts of the drawer 1.

Whilst one or more preferred embodiments of the present invention have been herein before described, the scope of the present invention is not limited to those specific 25 embodiment (s) , and may be embodied in other ways, as will be apparent to a person skilled in the art.

Modifications and variations such as would be apparent to a person skilled in the art are deemed to be within the scope of 30 the present invention.
