Structure for the composition of a frame.

The present invention consists of a structure for the composition of a frame, formed by a piece of a resistant sheet material, such as cardboard, plastic or the like, that forms a body that duly folded forms a box or housing capable of wrapping an article, for example, a canvas, which comprises a plurality of precut lines, and which, once the corresponding pieces have been cut and assembled, forms a frame or support frame for, for example, the canvas housed inside. Background and prior art

From a long time ago the frames for holding canvases are known, which are made up of wooden slats, normally provided with tie rods or ties. Said frames are often used to hold a canvas that extends from the front of said slats, to wrap the slats from the outside and towards the back, and finally said spiked (or currently stapled) canvas on the inner faces facing each other between yes or on the back faces of the slats.

However, this part does not know a device that allows a box or housing to be converted into a frame by cutting the precut lines that exist in the laminar surface defined by said box, so that, according to the invention to be proposes, the resulting frame can be adapted to multiple formats from a base piece that constitutes a generic standard.

The present invention therefore has a structure for the composition of a frame comprising a die-cut piece of a sheet material for the manufacture of a box by means of a suitable bending, and by cutting into pre-cut lines the formation of parts that duly joined will form a frame, for example for the fastening of a canvas contained inside the previously shaped box. The shaped box comprises handles and some side closures. Brief description of the drawings

As described, the present invention consists of a structure for the composition of a frame, which is constituted from a die cut piece (1). This sheet is a template that has two functions:

•

Forming an envelope (8) box or housing, which defines an internal hollow, and is capable of protecting a product, such as a canvas, sheet or any other product; Y

•

Form a frame for the support of, for example, a canvas, a sheet or any other laminar element.

The wrapper (8) is formed by folding the die-cut sheet piece (1) by means of parallel folds or folds towards one of the faces, and at least one and preferably two folds (those of the end portions) oriented opposite to the previous.

The die cut sheet (1) has defined on its surface a set of areas corresponding to uprights (2) and angular pieces (3) for the con fi rmation of two angular structures (13), with which it is possible to mount the frame ( 16) of the invention.

In order to form the envelope (8), it is provided that the die-cut sheet (1) comprises in hollow extreme central positions (5) that will perform the function of handles of the box that is formed. In addition, two sets of side closure tabs (6) of said box are arranged at the lateral ends.

These areas are formed by printed lines, fold lines and / or precut lines.

Some of these areas correspond to the uprights (2). Said uprights, in addition to the corresponding printed lines or pre-cut lines that define their flat shape, comprise a set of fold lines, so that once the cut and the bending are made, structures (12) are formed in the form of "U ”, With a centerpiece (10) and two wings the

3 EN 2358653A1 4

Terales (9). Each of the lateral wings (9) comprises at their ends two angular recesses (16), so that when the corresponding uprights are formed they allow miter mounting.

According to a preferred embodiment, the areas corresponding to each of the uprights comprise, on at least one of their faces, a set of printed cutting lines (7) corresponding to the different lengths that said upright can adopt. Said printed lines (7) will normally be parallel to each other, will be located symmetrically at both ends of each upright, and it is provided that they define different calibrated lengths of the uprights (2). For lengths shorter than the total length, then, the uprights (2) should be cut to a shorter length, following one of the corresponding printed lines (7).

In the die cut sheet there are also reinforcing elements (4) of the angular structures (13). Said reinforcing elements (4) of the angular structures (13) are capable of being bent to con fi gure a three-dimensional reinforcement structure (14) capable of holding said angular structure (13) internally and externally on one of the faces it forms. Normally they will be arranged on the face of the angular structure in which the two opposite ends are joined in the die cut sheet (1), thus constituting a connecting element between the separated ends. It is designated with

(15) the assembly of the angular structure (13) attached to the reinforcement structure (14).

Once the frame is assembled, the outer part of the three-dimensional reinforcement structure (14) located externally in the angular structure protrudes from said angular structure (13) in the same magnitude as the "U" shaped structures (12). conforming with these a flush surface.

The different elements will normally be joined by chemical adhesives or other mechanical bonding means.

2. Statement motivated according to articles 29.6 and 29.7 of the Regulations for the execution of Law 11/1986, of March 20, on Patents on novelty and inventive activity; quotes and explanations in support of this statement The patent application describes a structure for the composition of a frame constituted from a die-cut sheet that can be folded to form a wrap provided with handles. In the stamped sheet piece, some uprights and / or angular pieces are defined by means of printed lines, bending lines and / or pre-cut lines for shaping angular structures. The uprights of the frame are obtained by folding a series of lines achieving U-shaped structures that have angular recesses at their ends. They can have at least one of their faces a set of printed cut lines that correspond to the possible different lengths. In the die cut sheet, reinforcement elements of the angular structures are also defined which, when folded, form a three-dimensional structure capable of holding the triangular structures. It includes inside the die cut piece hollows that perform the function of handles when used as a wrapper. The materials to be used can be cardboard or plastic or similar. Document D01 describes the realization of a wrap suitable for containing a painting, canvas or poster. It is likely to become a frame. Part of a die cut sheet that can be folded to form a wrap. The laminar piece becomes a wrap by folding its die-cut lines and inside it allows the uprights to be contained. Once the envelope is deployed, it constitutes a rigid base where it supports the painting, canvas or poster and is tied by means of the uprights. Document D02 starts from a die cut sheet that constitutes or is part of a package. Said generally rectangular sheet is made of cardboard or similar material. It has folding lines that allow the development of rigid tubular elements that behave as uprights. Document D03 refers to a folding frame to support an ornamental motif or a drawing. Part of a single sheet piece that by cutting and folding marked lines leads to the obtaining of a frame or frame to support the ornamental motif. Although many documents have been found describing the realization of cardboard packaging or similar that can subsequently acquire other functionality such as serving as a frame for paintings, canvases or puzzles, none has been found that starts from a die-cut sheet in which its parts can be not only bent but also cut to be part of a future frame as claimed in the patent application. It is considered, therefore, that the patent application is new and has inventive activity according to Art.6.1 and 8.1 of Patent Law 11/86. State of the Art Report Page 4/4
