Description

Improved union for furniture structures, particularly tables.

The present invention is about a union perfected, for table structures or similar furniture.

Conventionally, tables or office furniture Similar consist of a frame with legs, where it supports a board higher. The frame is formed by stringers and crossbars joined between yes.

Conventionally, each piece of furniture or type of furniture Concrete requires a concrete frame. It is not possible to vary a same rack to configure different furniture (for example, in Modular furniture).

Racks are required that, using the same structure, allow you to vary your configuration, to adapt it to each concrete need and form different furniture. This is achieved with removable joints between stringers / crossbars.

It is also required to configure different racks, modular or not, varying the number of components - knots, stringers and / or crossbars - or by varying the number of pieces that affect the same knot.

US Patent 4702638 describes a knot for furniture structures, especially for tables, which consists of two pieces / lid that can be placed symmetrically face to face and having means of anchoring and mutual self-positioning; every one of the two pieces / cover has two grooves non-interns forming an angle between them and the pairs they are conjugated face to face to compress, between them, two crossbars or uprights of the furniture structure that have a radial incidence on this assembly forming an angle between they according to the amplitude and orientation determined by the angles Between the grooves.

The MU. DE29809994 describes a knot with a first through groove and second groove non-passer perpendicular to the first groove being able to compress between them three crossbars / stringers.

The modularity described for two or three crossbars do not solve the demand for multi-modularity for furniture especially for tables of office that should be able to get caught between them.

The perfected union of the application has solved the problem by having a horizontal groove through and a vertical through groove that are cut between them and two non-through grooves that are cut forming an angle (?) with the horizontal groove in the parts flanges / contours / lid.

The solution of the application gives 14 possibilities of conformation of the knot, that is, a great versatility.

To better understand the purpose of this invention, a preferred form of practical realization, susceptible to accessory changes that do not distort its foundation.

Figures 1 and 2 represent paths general plan of some furniture structures with several unions according to the invention, in each of which they affect more than a crossbar / crossbar (4) according to different shapes and / or angles.

In these figures only one of the pieces / cover (1a).

Figure 3 represents a general view in plant, similar to the previous figures, for an alternative way of angled stringers / crossbars (4) and with the other cover (1b) in operational disposition.

Figures 4 and 5 represent in details expanded in plan -figure 4a, 5a- and in profile -figure 4b and 5b- the pieces / cover (1a), (1b) with their conjugate conformations of self-positioning and anchoring.

An example of practical, non-limiting embodiment of the present invention. I dont know discarded at all other embodiments in which introduce accessory changes that do not distort its foundation; by On the contrary, the present invention also covers all its variants.

In accordance with the invention, and according to the represented embodiment, perfected union, for structures of furniture, particularly tables consists of individual pieces / cover (1st), (1b) configured as an open, confrontable single piece bowl symmetrically and with anchoring and self-positioning means mutual.

Each of said pieces / cover (1a), (1b) is noticeably flat. On its inner face it defines a plurality of grooves or throats (11) angled to each other, in the symmetrical confrontation of two caps (1a), (1b), hug in them to elements (4) - beams or crossbars - that are part of the structure / frame of the furniture in question.

These conjugated grooves (11) reach the edges / contour of the covers (1a), (1b), according to angles (?), (?), (?) different: they are open to one of the larger faces and may be transverse or oblique, through or not -see figures 4 and 5- without altering the essence of the invention.

For the embodiment shown - see figures 4 and 5- the means of self-positioning are games of bumps (12b) / pockets (12a) formed some (12b) in one piece / cap (1b) and the others (12a) in the piece / cover (1a) that fit tongue and groove in confronting them.

For the embodiment shown - see figures 4 and 5- the anchoring means are screw / nut sets, housed in pairs of holes (13a), (13b) facing each other, forming some (13a) in the part / cover (1a) and others (13b) in the part / cover (1b). Preferably, one of these holes (13b) carries the nut (14) embedded - see figure 5b-.

With this structuring the assembly of each stringer / crossbar (4) in a pocket / throat (11) defined in the opposing conjunction of two pieces / lid (1a), (1b). The screws housed in the holes (13a), (13b) and threaded to the nut (14) firmly hold each other to the stringers / crossbars (4) of the structure / frame.

The angular amplitudes (α1), (? 1), (? 1) between stringers / crossbars (4) comes given both by the angular amplitudes (?), (?), (γ) between pockets / throat (11) as per the quantity and orientation of stringers / crossbars (4) that converge in a Union.

In fig. 4a it is appreciated that the grooves are a through horizontal groove (11_ {2}) and a groove vertical through (11_ {1}) that are cut between them and two non-through grooves (11_ {3}) that are cut forming an angle (?) with the horizontal groove (11_ {2}) on the flanges / contours of the parts / lid (1a), (1 B).

Claims (1)

1. Improved union, for furniture structures, particularly tables, consisting of individual pieces / cover (1a), (1b), symmetrically confrontable and with means of anchoring and mutual self-positioning; each of said pieces / cover (1a), (1b) comprising a plurality of grooves (11) angled together and clashing in pairs to embrace between them a crossbar (s) or crossbar (s) (4) of the structure of the furniture (T) that radially affect said joint angled together, according to the amplitude and orientation determined by the angles between grooves, characterized in that the plurality of grooves (11) are a horizontal through groove (11_2) and a vertical groove through (11_ {1}) that are cut between them and two non-through grooves (11_ {3}) that are cut at an angle (?) with the horizontal groove (11_ {2}) in the flanges / contours of the pieces / cover (1a), (1b).
