Description

Title of the invention: Injected fitting with incorporated pins for mounting sofa boxes

[0001] Object of the invention

[0002] The invention, as described in the present description, relates to a fitting with incorporated pins for mounting sofa boxes, and provides, for the function for which it is intended, advantages and characteristics, described in detail below, which represent an advance over the current state of the art.

[0003] More particularly, the subject of the invention relates to a fitting of the type intended to allow the assembly of two parts of a piece of furniture, in particular intended to assemble perpendicularly two adjacent partitions of the box of a sofa bed, which has the advantageous feature of having, integrated as an integral part of the injected part itself, which constitutes the fitting, pins or pegs which, intended to be inserted into holes provided for this purpose in the partitions, give robustness to the assembly, and allow, among other advantages, easier and faster assembly of said sofa bed. Technical field

[0004] The field of application of the present invention belongs to the furniture sector and more particularly to the field of industry dedicated to the manufacture of fittings and accessories for the assembly of furniture. State of the art

[0005] In the furniture and carpentry sector, it is common to use pins or dowels to allow a more robust assembly between two parts of a piece of furniture, for example between two boards or partitions assembled at an angle. These pins or dowels are generally made of a section of wood, metal or other material, cylindrical or slightly conical, which is either inserted fitted into respective perforations provided for this purpose in the two parts to be joined, generally by adding glue, or fixed permanently in one of the parts, then fitted by pressure in the other. This type of assembly, although it provides robustness, has the disadvantage of being laborious to set up and involving the introduction of a greater number of parts.

[0006] Furthermore, it is also well known that fittings are used to assemble adjacent pieces of furniture by screwing, said fittings being for this purpose generally made of a simple perforated plate, made of metal or another material, designed to insert the fixing screws. This type of assembly, although less robust, is faster.

[0007] Thus, the essential objective of the present invention is the development of an improved type of fitting which combines the two types of assembly, that is to say with pins and screwing, taking advantage of the advantages of each, but without presenting the disadvantages.

[0008] Furthermore, a second objective of the invention is to provide a fitting specifically designed to facilitate the assembly of sofa bed type furniture, in particular for the assembly of the box which corresponds to the lower part of the sofa and in which, often, feet are included at the corners, at the point where the partitions of said box are assembled, given that the fittings currently existing for this type of furniture do not allow the feet to be changed without first dismantling the fitting itself.

[0009] Furthermore, and with reference to the current state of the art, at least to the applicant's knowledge, there is no other fitting with integrated pins for mounting sofa boxes, nor any other invention of similar application, having technical, structural and constitutive characteristics identical or similar to those claimed herein. Statement of the invention

[0010] The injected fitting with incorporated pins for the assembly of sofa boxes proposed by the invention constitutes an ideal solution for the aforementioned objective which, at the same time, represents an improvement over the solutions already known, the characteristic details which make it possible and which distinguish it being conveniently included in the final claims which are attached to this description.

[0011] The invention proposes, as previously indicated, a fitting intended to allow the assembly of two parts of a piece of furniture, in particular to assemble at right angles or perpendicularly the adjacent partitions of the box of a sofa bed, with the particularity that said fitting, consisting of an angular plate with at least two perpendicular sides and provided with perforations on said two sides to allow the insertion of fixing screws, is distinguished in that it further comprises several pins which are integrated in the injected part itself, as an integral part thereof, projecting perpendicularly from the external face of the two sides, so as to be designed to be inserted into holes provided for this purpose in the partitions.

[0012] Furthermore, in one embodiment, the plate which constitutes the body of the fitting is an L-shaped piece, on both sides of which the pins protrude from the external face, and is mainly designed for mounting sofa boxes without feet, so that the adjacent partitions of the box are assembled directly to each other at right angles.

[0013] Furthermore, in another embodiment, the plate that constitutes the body of the fitting is a chamfered L-shaped piece, designed to mount a sofa with legs by interposing a leg between the ends of the adjacent partitions, at the four corners of the box. In other words, the angular plate of the body of the fitting is folded in three planes, two ends, from the external face of which the pins protrude, which are perpendicular to each other, and which are those that assemble the respective partitions of the box, and a central chamfered plane with holes for screwing a leg on the external part, between the two ends of the partitions.

[0014] In addition, the body of the fitting comprises, on the internal face, a series of transverse reinforcing bars which give greater resistance to the part.

[0015] It should be clarified that the shape of the fitting may vary, both with regard to the L-shaped or chamfered L-shaped body, which may be quadrangular, round or of another configuration, and with regard to the position, thickness, number and inclination of the pins that protrude from it, which may vary according to the needs or design of each case.

[0016] Thus, the injected fitting described, with integrated pins for mounting sofa boxes, constitutes an invention whose main advantage is to allow easy assembly of the sofa, saving time during assembly, given that it introduces integrated pins.

[0017] It also allows the legs (or corner pieces) to be changed without having to dismantle the sofa, since the legs are screwed onto the external part, which avoids the existing drawback that, in all sofa fittings, when a leg needs to be changed, the sofa must first be dismantled to make said change. With the fitting of the present invention, this is not necessary, since the leg is fixed to the chamfered face of the fitting, on the external part of the box, and it is not necessary to dismantle the latter from the sofa to change only the leg.

[0018] Another advantage is that the use of this fitting allows to reduce the cost of the sofa, because the machining of the uprights and feet that make up the box or drawer of the sofa is less expensive and simpler.

[0019] Thus, preferably, the fitting of the invention is presented in two variants, one for a sofa box without legs or corner pieces, composed only of two uprights (or long partitions) and two transverse pieces (or short partitions), and the other where the sofa box is composed of two uprights (or long partitions), two transverse pieces (or short partitions) and legs or corner pieces in the four assemblies of the partitions or corners.

[0020] On the other hand, the fitting of the invention also has the advantage of allowing greater play during assembly to adjust the parts of the box, so that they are completely adjusted and perfect to the eye of the end user.

[0021] Preferably, the fitting is made of a fiberglass part, without limitation, because it can also be made of any other injected material.

[0022] Finally, the fitting has several reinforcement points inside the part which give it greater resistance. Description of the drawings

[0030] Preferred embodiment of the invention

[0031] With reference to the aforementioned figures, and in accordance with the numbering adopted, it is possible to observe in them two examples of embodiment without limitation of the injected fitting with incorporated pins for the assembly of sofa boxes of the invention, comprising what is indicated and described in detail below.

[0032] Thus, as shown in said figures, the fitting (1) of the invention, suitable for obtaining a right-angled assembly of two partitions (2) of a sofa box (3), is of the type consisting, essentially, of a body (10) in the form of an angular plate with, at least, two end sides (11) in which there are one or more perforations (13) designed for the insertion of fixing screws (4) with which they are fixed to the respective ends of said partitions (2).

[0033] Furthermore, compared to this already known configuration, the fitting (1) is distinguished by the introduction of at least two pins (14) integrated as an integral part thereof, which project from the external face (a) of the two end sides (11) of the body (10) at an angle of the fitting (1), and which are designed to be inserted adjusted in orifices (not shown in the figures) provided for this purpose in the partitions (2).

[0034] In one embodiment, intended for the assembly of partitions (2) in boxes (3) without feet, the plate constituting the body (10) of the fitting (1) is an L-shaped part with only two end sides (11) perpendicular to each other from which several pins (14) project perpendicularly from the external face (a) thereof, interposed between several perforations (13) for the insertion of fixing screws (4). Preferably, three pins (14) project from each side (11), as shown in Figures 1-A and 1-B.

[0035] Furthermore, in another embodiment, shown in Figures 2-A and 2-B, intended for the assembly of a sofa box (3) with legs (5) interposed between the ends of the adjacent partitions (2), the plate which constitutes the body (10) of the fitting (1) is a chamfered piece, that is to say folded in three planes which define two end sides (11) perpendicular to each other, from the external face (a) of which pins (14) project perpendicularly and comprising perforations (13) for the insertion of fixing screws (4) with which they are assembled to the respective adjacent partitions (2) of the box (3), and a chamfered central side (15), in which openings (16) are also provided, for screwing a leg (5) to the external part of said side, between the two ends of the partitions (2), as shown in Figures 3-A and 3-B.

[0036] Preferably, the aforementioned openings (16) on said chamfered central side of the body (10) of the fitting have a groove or oblong shape, in order to be able to precisely adjust the height at which the foot is fixed and to align the four feet of the box (3).

[0037] Furthermore, the body (10) of the fitting comprises, on its internal face (b), a series of transverse reinforcing bars (17), which increase its resistance.

[0038] Furthermore, although the fitting (1) can be of any size, depending on the dimensions of the box (3) in which it is incorporated, preferably its dimensions are between approximately 5 cm and 20 cm in height (h) and more or less 2 cm wide (1), in correspondence with the end sides (11) from which the pins (14) protrude.

[0039] In all cases, preferably, the fitting (1) is made of a single piece obtained by an injection process, and preferably a piece made of fiberglass, even if it can also be made of another injected material.

[0040] The nature of the present invention as well as the manner of putting it into practice having been described in sufficient detail, it is not considered necessary to explain it further so that any person skilled in the art can understand its scope and the advantages resulting therefrom, and it should be noted that, in its essence, it can be put into practice according to other embodiments which differ in details from those indicated by way of example, and for which the protection claimed will also apply, provided that its fundamental principle is not altered, modified or transformed.
