Description

The present patent invention is applied to furniture area, and refers to a system for bending pieces and a system for quick mounting applied to a cabinet body, specially steel cabinets, for joining took apart pieces by fitting and bending of the steel piece locking the pieces one to another without needing screws, connectors, tools or skilled labor. The cabinet body presents bipartite backside section of which two pieces are joined by quick fitting in one piece which side section, top and bottom parts fit to, resulting in the box. This box having pieces non-locked yet receives in its four corners simple manual bends at the steel, forming the cabinet box for doors and shelves to be immediately fitted thereto.

The mounting systems currently used to mount box of took-apart steel-plated cabinets, specially in the backside section, are fixed by joining the side sections, top and bottom parts to the back part, the side sections, top and bottom parts having bends that when in contact with the backside flat plate are joined using screws and nuts that pass through coincident bores. In another known system, the back part presents a small backlash made by the bend in contact with the side sections, top and bottom parts of the cabinet having U-shaped bends at the backside part and being fixed using screws and nuts or self-tapping screw through coincident bores.

In turn, the systems currently used to installation of cabinets on a wall commonly use a device that is fixed to the backside of the backside section of the cabinet box, which is fitted to a panel having recesses to be fixed to the wall or that will be able to be fixed to the wall using bores on the back part that are positioned at the installation place and fixed through screw and bush.

The document no BR 102014016208-9—entitled “SISTEMA CONSTRUTIVO DE MONTAGEM APLICADO EM ARMÁRIO” (CONSTRUCTIVE MOUNTING SYSTEM APPLIED TO CABINET)—consists of a wooden cabinet, comprising two side plates, a cap, a fixed middle shelf, a bottom plate, a backside plate, a double-sheet door, the wooden cabinet being provided with adjustable shelves, finishing bungs and supporting bungs, bun feet, screws, bulkhead plate and handles. The novelty consists of the fact of being provided with grooved plates, or slots designed for fitting and locking, reducing the fixation using screws, and eliminating weld. It differs from the present system for presenting wooden plates and finishes, and for fitting and locking using screws, while the present patent above described presents a quick-mounting system through pieces of steel plates, the steel having fits and bends on itself.

The document no PI 0603865-4, owned by the Applicant of the present patent, is a CABINET MOUNTING SYSTEM WITH FIXING ELEMENT (“SISTEMA DE MONTAGEM DE ARMÁRIO COM ELEMENTO DE FIXAÇÃO”), presents a structured assembly of bent- or stamped-steel molded pieces, the shape and size substantially corresponding to the fit one another, which will take place concurrently at the moment of mounting, gradually by coupling through a common fixing element. The side profiles are provided with U-shaped bend, holes for fitting the fixing element, in addition to holes for fitting the backside face; central faces or caps. The side profiles are provided with slots for coupling to the U-shaped side parts, hole for fitting the fixing element pin, and coincident hole and for juxtaposition to the hole of the fixing element; the fixing element of the body being provided with a pin at the bottom part in addition to holes, and a fit for receiving a hinge and a screw allowing the hinge of the door to be fixed. After the door having received the hinge fit, this is coupled to the element through the fit and fixed to it by the screw screwed into the hole through the hinge fit. It differs from the present system due to the fixation of the pieces, and the fixation of the cabinet to the wall takes place through screws, fixing pins and element, while the present patent described herein presents a system for quick mounting through steel plate pieces, the steel having fits and bends on itself, dispensing with screws, connectors, tools or skilled labor.

The document no MU 8903064-8—entitled “Disposição construtiva introduzida em dispositivos de montagem e fixação de partes componentes de armário metálico” (Constructive Arrangement inserted into fixing and mounting devices of parts composing metallic cabinet)—presents a fixing and mounting device of the couple of pieces composing the bottom; fixing and mounting device of the pieces composing the side parts joined to the upper crossbar; fixing and mounting device of the shelves joined to the set of racks and fixing and mounting device of the backside part of the top component, new constructive arrangement being inserted into the parts composing right and left side pieces; right and left bottom pieces, rack piece, shelf piece and top piece. It differs from the present system for presenting locking bar, crossbar and extruded column supporting the cabinet structure, while the present patent do not have structural pieces, only steel plate pieces with fits and bends on the steel itself dispensing with screws, connectors, tools or skilled labor.

The system of mounting the steel cabinet box of the present patent consists of loose pieces in steel plates having predefined bends forming parts of backside section, side sections, top part, and bottom part that by only fitting one to another they form the cabinet box having no shelves and doors yet. This box formed by fitted parts being not locked yet will receive simple manual bends at the steel plate, one bend on each of the four corners of the cabinet box where the backside, side part, top or bottom sections are. These bends can be made without needing tools allowing for a simplified and quick mounting that can be performed by any person, thus forming the steel cabinet box locked and sufficiently stiff to receive shelves and doors, if needed.

The systems for quick mounting applied to cabinet body mating a system for bending pieces and a system for quick mounting applied to a cabinet body present the following advantages:

• • allowing for the quick and secure mounting of the components through bends;
  • enabling pieces of the cabinet box to be locked in an effective and resistant manner;
  • providing for fits to the steel itself by means of bends;
  • allowing for the cabinet body mounting without needing specific connectors and tools;
  • enabling the cabinet body mounting to be performed by only one person needing no a skilled person.
