Definitions

  • the present invention relates to a door for commercial furniture.
  • Such doors are made of sheet metal.
  • they are usually composed of two metal sheets, for example made of stainless steel, which are blanked, bent, and mutually joined so as to form a box-like structure which, in the case of use in refrigerators or in pieces of furniture requiring particular heat insulation features, is filled with foamed insulating material, such as polyurethane or the like.
  • Conventional doors besides having handle-like elements, which are provided to the user for closing and opening and are obtained either by pressing the front metal sheet or by welding separate parts prior to assembly, also have elements for rotatable coupling to the pieces of furniture for which they are intended.
  • These rotatable coupling elements typically constitute the male or female component of a hinge associated with the corresponding component, which is fixed to the piece of furniture, when the door is assembled.
  • a first embodiment entails, in a back region of the door, the application of an internal reinforcement plate for each hinge element to be applied, said plate being perforated together with the back of the door, thus connecting the male or female hinge element externally to said door by means of screws or other threaded elements.
  • a second embodiment entails the formation, at the transverse edges of the door, of seats providing the female components of the hinges, or the fixing of pivots providing the male components of said hinges.
  • the first embodiment is rather complicated from the point of view of production, since it is necessary to fix the plate, usually by welding, perforate said plate, and apply the hinge element, which is a separate part, prior to assembly.
  • the second embodiment has the main drawback that, in order to achieve door closure and opening, it must provide for chamfering of the corner of the piece of furniture that corresponds to the hinges; its opening kinematics would in fact unavoidably make it interfere with said corner, as experience has shown.
  • both embodiments are reversible, that is to say, doors manufactured as described above can be fitted equally to the right side or to the left side of the piece of furniture, the formation of handles by pressing the front metal sheet or the application of said separately provided handles eliminates the above mentioned reversibility, and this requires not only greater skill on the part of the assembly personnel but also separate production lines.
  • both embodiments have systems for hinging to the piece of furniture that are clearly visible and therefore certainly do not have an optimum aesthetic effect.
  • a principal aim of the present invention is to provide a door that solves the drawbacks of the conventional types pointed out above, in particular by offering complete reversibility, as well as an opening and closing kinematics that never makes it interfere with the piece of furniture.
  • an object of the present invention is to provide a door that is constructively very simple and is obtained while preserving, if not improving, good structural strength features.
  • Another object of the present invention is to provide a door having a pleasant aesthetics and in which the handles are concealed adequately for this purpose.
  • Another object of the present invention is to provide a door that allows easy cleaning and does not have regions where dirt accumulates, with a high bacteriological risk.
  • Another object of the present invention is to provide a door that can be manufactured with conventional technologies and the costs whereof are competitive with those of currently commercially available doors.
  • Another object of the present invention is to provide a door that is ergonomically competitive with conventional models.
  • a door for commercial furniture is generally designated by the reference numeral 10.
  • the door 10 is constituted by a box-like body 11 formed by associating a front metal plate 12, a rear metal plate 13, two tubular uprights 14, and two likewise tubular cross-members 15.
  • the front plate 12 and the rear plate 13 are both folded and made, in this case, of plastic-coated sheet metal, whereas the two uprights 14 and the two cross-members 15 are constituted by an extruded element made of plastics.
  • the two cross-members 15 are identical one another and are substantially L-shaped, so that each one forms a concealed handle, their concave portions being directed towards the piece of furniture (not shown in the figures) on which the door 10 will be mounted.
  • both the uprights 14 and the cross-members 15 have, in outer edge regions 16 and along their entire length, two flexible flaps 17 and 18 having respective facing free ends; the flap 17 accommodates by abutment, in its inner part, the folded portion of the front metal plate 12, whereas the flap 18 provides a stop element ensuring the fixing of said plate.
  • the rear plate 13 is fixed to the uprights 14 and to the cross-members 15 by insertion in slots 19 formed therein and in which its folded portion produces slight interference.
  • the uprights 14 and the cross-members 15 substantially produce a perimetric frame for the front plate 12 and for the rear plate 13; said frame is fixed further by four corner elements designated by the reference numerals 20 to 23 in the figures.
  • corner elements 20 and 21 are identical one another, and each one is constituted by a shaped body 24 preferably made of injection-molded plastics and from which two substantially prism-shaped mutually perpendicular pins, not shown in the figures, protrude; each one of said pins fits respectively inside the cavities of a corresponding upright 14 and of a corresponding cross-member 15.
  • the corner elements 22 and 23 are identical one another, and each one is constituted by a body 25 preferably made of injection-molded plastics, from which two substantially prism-shaped and mutually perpendicular pins 26 and 27 protrude together with a substantially prism-shaped lug 28 that remains substantially on the plane of arrangement of said body 11.
  • each one of the pins 26 and 27 fits, upon assembly, in a corresponding cross-member 15 and upright 14.
  • the lug 28, in this case, is perforated so as to form a blind hole 29, inside which a pivot 30 is inserted; said pivot forms, in association with the lug 28, the male component of an external back hinge the female component whereof is rigidly coupled to the piece of furniture which, as mentioned, is not illustrated in the figures.
  • the body 11 once assembled, is filled with thermally insulating material, such as foamed polyurethane or the like.
  • hinge components related to the door executed according to the invention, have considerable constructive simplicity, with a saving in production steps with respect to conventional types; they in fact require only assembly by simple insertion in the uprights and in the cross-members after being produced by injection-molding plastics or by virtue of another production process.
  • the hinge components according to the invention furthermore produce a door movement by virtue whereof said door never interferes with the piece of furniture on which it is mounted.
  • hinge components furthermore causes them to be fully uniform from the visual point of view with the door, and this provides a pleasant aesthetic effect.
  • the shape of the door according to the invention being without regions that are particularly difficult to reach for cleaning after assembly, accordingly allows assured and effective hygiene.
  • radiused lines as well as the frame of tubular elements made of plastics, give the operator assurance of safe use without danger of cuts or other hazards.
  • the present invention is susceptible of numerous modifications and variations, all of which are within the scope of the inventive concept; thus, for example, instead of inserting the pivot in the lug, it is possible to leave the hole therein, thus constituting the female component of the hinge, and the pivot can be provided monolithically with the lug.
  • the materials employed, as well as the dimensions, may be any according to the requirements.
