The invention also claims a front part of a shelf or drawer, the front part comprising: an elongated support projecting from a surface capable of supporting the shelf or the bottom plane of the drawer, facing in the use condition towards the drawer or the surface of the centre of the shelf, said surface comprising a protruding element coupled to the elongated support by inserting the protruding element in a complementary longitudinal cavity present in the projecting support.

Description

Assembly system and method for drawers or shelves

Technical Field

The present invention generally relates to mounting systems and methods for shelves or drawers for furniture.

Background

Furniture shelves or drawers, in particular wooden shelves or drawers, are constructed by combining four sides to form a square or rectangular frame for supporting a bottom plane. The usual technique is to form a C-shaped piece by fixing together three sides-the bottom and sides of a drawer or shelf, followed by a connection to the front.

The front portion is often just a wooden panel, secured to the C-shaped member with some anchoring elements. In order to support the bottom plane, on the surface of the table facing the inside of the drawer, an elongated profile is fitted, which will act as a support for the edge of the shelf.

Currently, the elongated profile is attached to the plate by means of a sleeve inserted with pressure into a hole of the plate, but this mounting method has several drawbacks. The casing is very expensive and the drilling of the plate must be very precise. Even if only holes are misaligned or misaligned (out of pitch), the assembly may not be as standard.

FIG. 2 shows an exploded three-dimensional view of the front component of the shelf or drawer;

Detailed Description

In the drawings, like reference numbers indicate identical or conceptually similar parts, and elements are described as in use. Some reference numerals are omitted in order not to crowd the drawings.

Fig. 1 shows a shelf or drawer 12, the shelf or drawer 12 comprising a frame formed by a front section 14, a bottom section 16 and two side sections 18. The

sections

16, 18 are, for example, tubular members, with the ends cut at 90 degrees to fit together. The

sections

14, 16, 18 are assembled to form a generally rectangular or square frame. The bottom of the shelf 12 is indicated at 20 and in the use position lies in a horizontal plane.

To mount the shelf or drawer 12, the front section 14 is secured to a C-shaped assembly formed by the combination of a bottom section 16 and two side sections 18.

The front section 14 is constituted by a flat plate 30 or comprises a flat plate 30, the flat plate 30 having a main surface S facing the bottom section 16 in the use state, i.e. facing the interior of the drawer or shelf 12.

On the surface S, an anchoring element 42 is fixed, for example with a screw 40, near the end of the plate 30, the screw 40 and the anchoring element 42 being adapted to couple the plate 30 to the free end of the segment 18.

On the surface S, pairs of holes 50 are made centrally, by means of which holes 50 some dowels 54 are attached to the surface S with screws 52. All of the holes 50 are aligned so that the dowels 54 are on the same X-axis, see fig. 3.

With reference to fig. 6, the dowel 54 is a block, for example parallelepiped-shaped, and comprises a section or head 56, which section or head 56 has a larger or enlarged cross section, said section or head 56 projecting in an overhanging manner from the surface S.

The rows of dowels 54 form guides for coupling the elongated profile 60 to the plate 30, see fig. 4 and 6. The elongated profile 60 is a strip 62 extending elongated along an axis, the strip 62 comprising a cavity 64 and a bracket 66.

The cavity 64 is complementary in a negative manner to the shape/volume of the dowel 54, while the bracket 66 remains horizontal in the use condition.

The elongated profile 60 is coupled to the dowel 54 by having the cavity 64 facing the surface S.

The elongated profile 60 is then slid horizontally parallel to the surface S from the edge of the plate 30 towards the centre (see arrow F), inserting in sequence the dowels 54 one at a time into the cavities 64.

Referring to fig. 5, at the end, the elongated profile 60 is integral with the plate 30 on the surface S, and the elongated profile 60 cannot be disengaged from the dowel 54 (unless extracted in the opposite direction) due to the segment or head 56.

Thus, the elongated profile 60 can serve as a support for the bottom 18 when the assembly is complete. Preferably, the bracket 66 includes a longitudinal groove 68, for example, having a T-shaped cross-section. The longitudinal groove 68 is placed in front of the surface S in the condition of use, for example oriented upwards, and serves for slidingly fixing an element with a complementary T-shaped projecting head or for anchoring the internal components of the drawer or shelf 12.

It should be noted that:

the number of dowels 54 may vary, even if only one dowel 54 is required if dowel 54 is long enough; and

the shape of the dowel 54 may vary, it being sufficient if the dowel 54 protrudes from the plate 30 to support the elongated profile 60. The presence of the head 56 creates a linear prism pair between the dowel and the elongated profile, which is advantageous, since it prevents the elongated profile 60 from coming out,

but is not required.

Even the manner in which the dowel is secured to the plate 30 may vary, such as by adhesive. Alternatively, the plate 30 may be made by: on which one or more protruding parts functionally similar to the dowel 54 are integrally made. This is easy if, for example, the plate 30 is a piece molded from plastic. The plate 30 is preferably made of wood.

It should be noted that the support for the plane 20 can be a single elongated profile 60, or a group of several smaller elongated profiles arranged along the X-axis. This facilitates, for example, assembly, avoiding the insertion of many dowels 54 along the long travel of the elongated profile 60.
