Definitions

• the present invention relates to a multipurpose drawer for commercial furniture.
• This structure entails using metallic material, usually stainless steel, to form the drawer, and substantially comprises a metallic housing inside which the rails for the sliding of one or more compartments inside said housing are fixed; the rails are separate elements prior to assembly, and the compartments are also made of metallic material.
• fascias are applied to the compartments that slide inside the drawers, both for aesthetic and functional requirements; handles for moving said compartments are formed or applied to said fascias, generally by molding but also by connection by welding or by virtue of mechanical means.
• fascias are currently connected to the corresponding compartments by welding or by virtue of mechanical means.
• a principal aim of the present invention is to provide a multipurpose drawer the constructive structure whereof can adapt to a wide range of requirements in the field of commercial furniture.
• an object of the present invention is to provide a multipurpose drawer the constructive structure whereof considerably simplifies the processes required for its production with respect to those required for conventional drawers.
• Another object of the present invention is to provide a multipurpose drawer the production whereof minimizes the requirement of specialized labor. Another object of the present invention is to provide a multipurpose drawer the quality level whereof, as a product, is competitive with that of conventional models. Another object of the present invention is to provide a multipurpose drawer that is durably reliable as regards both its operation proper, and as regards any specific features for containing fumes or for protecting substances placed inside it.
• Another object of the present invention is to provide a multipurpose drawer having competitive costs with respect to conventional ones and furthermore allowing to apply any fascia to a corresponding compartment in order to obtain an optimum aesthetic and functional effect.
• a multipurpose drawer for commercial furniture which comprises a housing inside which one or more compartments are slidingly supported, characterized in that said housing is made of plastics and in that raised portions extend monolithically from the internal surface of said housing and/or grooves are formed therein, said raised portions and/or grooves being adapted to form guides and/or rails for the sliding of said one or more compartments in cooperation with carriages.

• a multipurpose drawer for commercial furniture is generally designated by the reference numeral 10.
• the drawer 10 comprises a housing 11 inside which, in this case, a compartment 12 is slidingly supported.
• the housing 11, again in this case, is constituted by two shells 13 and 14 that are mutually superimposed and connected in a snap-together manner along their respective edges.
• the shells 13 or 14 are mutually connected by the interlocking of respective tabs 15 extending monolithically from their edges; each tab has a hook-shaped end, with which it is anchored to a corresponding hollow 16 formed on the other shell 13 or 14 with respect to the one with which it is monolithic.
• the housing 11 is substantially symmetrical.
• the shells 13 and 14 are furthermore formed by molding plastic material, and two identical pairs of raised portions extend from the internal surface of each one of said shells.
• each one of the pairs are designated by the reference numerals 17 and 18 respectively. Both the raised portion 17 and the raised portion 18 of each pair run substantially longitudinally with respect to the housing 11 and over almost all of its length, and are furthermore located in regions that are substantially adjacent to those that become side walls when the housing 11 is assembled.
• the raised portions 17 and 18 are substantially parallel to each other and have respective transverse cross-sections that are both substantially trapezoidal; however, the raised portion 18 is higher than the raised portion 17.
• Each pair, which as mentioned is constituted by the raised portions 17 and 18, forms substantially two rails, provided by said raised portions 17 and 18, and a guide formed by their respective mutually facing surfaces and by the internal surface of the housing 11.
• Carriages 20 and 21 slide in the guides 19.
• the carriages 20, which slide on the upper part of the drawer 10 after assembly is completed are constituted by a frame 22 that forms substantially two open seats inside which two rollers 23 run.
• the carriages 21 are instead constituted by a frame 24 in which three seats are formed; corresponding rollers 23a run inside said seats.
• rollers 23 and 23a related to the carriages 20 and to the carriages 21 are identical to each other in this case and, again after assembly is completed, are in rolling contact with the inner surface of the housing 11 and with the outer surface of the compartment 12.
• rollers 23 related to the carriages 20 are in rolling contact with the upper part of an edge 25 formed perimetrically in the compartment 12.
• the rollers 23a related to the carriages 21 are instead in rolling contact with the lower outer surface of the compartment 12, where two depressions 26 have been formed; each one of said depressions is related to a carriage 21, and said depressions are mutually parallel and longitudinal and are furthermore shaped so as to correspond to the raised portions 17 and 18 that constitute the rails and the lower guides.
• the four pairs, each constituted by the respective raised portions 17 and 18, the carriages 20 and 21, as well as the depressions 26 and the edge 25, all cooperate to the sliding of the compartment 12 inside the housing 11.
• raised portions 27 have been formed on the bottom of the compartment 12; when the compartment 12 is extracted, they abut against corresponding raised portions 28 formed on the internal surface of the housing 11, causing the downward tilt of said compartment 12 without making it bear on the carriages 20 which, as mentioned, are arranged in an upward region.
• Said raised portions 27 can be conveniently provided if the compartment 12 is used as a filter shakeout tray.
• a connecting element 29 made of plastics is frontally fixed to the compartment 12 through mechanical means, such as for example bolts or the like, that are not shown in the figures, and by interposing, in this case, a metallic frame 12a.
• Said connecting element 29, which is shaped frontally so as to form a handle 29a, is adapted to fix a fascia 30 of any kind to the compartment 12.
• the fascia 30 is, in this case, made of sheet metal shaped so as to form a perimetric edge 31 that provides an undercut and a central region 31a that is open for access to the handle 29a but conceals said handle from sight. %
• the connecting element 29 is shaped so as to match the internal surface of the edge 31 and has, in some of its regions adjacent to said edge 31 upon assembly, through holes 32 that are shaped so as to substantially follow its perimetric shape; each one of said holes has a corresponding forming surface having a raised portion 33 in a region located towards the edge 31 upon assembly.
• the connecting element 29 furthermore comprises expanding elements 34, each whereof is shaped so as to correspond to a matching hole 32, inside which it is inserted, thus pushing outwardly the corresponding raised portion 33; this entails the outward expansion of a respective perimetric portion of the connecting element 29.
• the materials, so long as they are compatible with the contingent use, may be any.
