Definitions

• the subject of the invention is a method of manufacturing furniture for assembly by tubular profiles. It also relates to a profiled element of any length, or "profiled", more especially intended for the assembly of furniture comprising at least two side panels connected by two or more transverse panels as well as the furniture itself, manufactured according to process.
• the method according to the invention overcomes these drawbacks; it allows, by the use of profiles of particular section, forming a cross member and squaring elements for the side panels and stiffening elements for the plates, and it allows the creation of pieces of furniture which are themselves new in their structure and which can easily be assembled side by side to form sets of two or more elementary pieces of furniture.
• the profiles are produced, in a known manner, by elements of great length, generally made of a light and ductile metal alloy, such as an aluminum alloy, or also made of relatively rigid plastic, the elements of great length have a constant profile (or section shape) and are later cut into elements having the required length.
• the profile according to the invention is more specifically designed to constitute an assembly and connection element forming a cross between two side panels of a piece of furniture and a support element for one or more intermediate plates intended to support the objects to be stored. .
• the extruded profile according to the in-vention has a tubular main body and is remarkable in that it comprises, on the one hand, at least one longitudinal tubular element of substantially circular inner section, integral with one at least internal faces of its walls and intended to receive a fixing screw on a panel of a piece of furniture, and, on the other hand, at least one wing arranged projecting transversely to one of its external walls and intended to maintain or support an element of the piece of furniture, such as a tray1 tubular element and the said wing also coming from extrusion with the profile itself.
• the section of the profile is preferably close to that of a rectangle elongated in the transverse direction to the projecting wing, its ends being cut off at right angles to the direction of extrusion, this arrangement makes it possible by simple tightening at the bottom of two screws crossing corresponding apertures formed respectively in two opposite panels and engaged in the two previously threaded ends of the tubular element, to produce by pressing the panels against the bearing polygon constituted by the end of the tubular body the area itself of the profile and the wing which is transverse to it, a very good parallelism between the said panels.
• the piece of furniture comprising at least four profiles of the type defined above, fixed, in the same way, in the vicinity of the four angles of each panel, a perfectly rigid parallel-piped piece of furniture is thus formed.
• the profiles are arranged in a manner such that the transverse wings are oriented two by two towards one another and in the same plane so as to support a plate by group of two corresponding profiles.
• the trays can, for example, be placed in pla-ce after assembly of the carcass of the piece of furniture constituted, as has just been said, by the two panels joined by the profiles and, in this case, they are simply placed on the wings that face each other.
• some of the plates may also have, on each of their longitudinal edges, a deep mortise intended to receive the wing of the corresponding profile.
• the plate is put in place during the assembly of the carcass and is thus made permanently prisoner of the latter.
• This provision is particularly essential when it is desired to ensure an invariable distance between two trays which, themselves, must keep prisoners of the vertical elements of the piece of furniture, such as partitions or rows of rigid wires intended to maintain, in position vertical, for example recorded books or discs.
• two or more elementary pieces of furniture thus constituted can be joined in juxtaposition with the addition of finishing profiles masking the joints between two pieces of furniture or end finishing panels.
• FIGS. 1 to 6 are cross sections of six different embodiments of profiles according to the invention
• FIG. 7 is a section, with cutouts and approximations, parallel to the side panels of a piece of furniture assembled by sections according to the invention
• FIG. 8 is a variant of FIG. 7
• FIG. 9 is a section through IX -IX of Figure 8
• Figure 10 is a top view of two furniture according to the invention, joined in juxtaposition with interposition of finishing profiles and installation of an end finishing panel.
• the section A is made of a light aluminum alloy and has been obtained, in a known manner, by extruding the metal through a suitable die; he introduces :
• a main tubular body 2 of elongated section having the small flat walls 4 and 6 perpendicular to a flat wall 3 of greater width while the fourth wall 5, which corresponds to the wall 3, is concave,
• the tubular element 7 is tapped at each of its ends so as to receive screws 11 for assembling the side panels of the cabinet.
• the wing 10 is intended to receive and support one of the longitudinal edges of a shelf or tray 12, the opposite edge of which will be carried by the wing of a similar profile and of opposite orientation arranged in the same way between the two side panels of the furniture made up as described in the introduction.
• the wing contributes, by its end edge, to constitute the support polygon of the profile on the corresponding panel and thus to increase the stability or cohesion of the assembly in the direction corresponding to the short sides 4, 6 main body 2.
• the profile B has a tubular main body 2 of constitution analogous to the profile A, which also carries on the internal faces of its walls a tubular element 7.
• the profile B differs from the profile A in that the wing 10b, functionally homologous to the wing 10 is, here, carried in the middle of the height of the wall 3b.
• This arrangement makes it possible to have on the wing 10b a plate 12b, of suitable thickness so that it comes to be situated, by its upper face, in the immediate vicinity of the upper face 6 of the profile B.
• This arrangement which is also the one in figure 5, would still allow, as it is shown in this last figure, to support a plate 12e, in which a deep longitudinal mortise 13e has been formed, of dimensions such that the wing 10b or 10e ptiisse be engaged there, possibly by force.
• the section C which carries the wing 10c at its base is of proportionally greater height than the section A; it therefore carries two longitudinal tubular elements 7c symmetrically distributed on either side of the central part of the profile considered in section.
• Such a profile has the advantage of being able to constitute, for example at the upper plate and on the front of the piece of furniture a border making it possible to hide the lower part which it is desired to conceal, of an apparatus such as a reading table for microgroove discs.
• the profile D has a tubular main body 2d proportionally reduced and whose wall 4d, which corresponds functionally to the wall 4 of Figure 1, directly carries the longitudinal tubular element 7d.
• the large walls 3d, 5d are extended, beyond the small wall 4d, so as to. constitute two walls 14d, 15d, which define, with a median wall 16d carried by the wall 5d in the middle, and of the same orientation and extension as the first two, two grooves 17d intended to receive, as will be seen on the Figure 7, either each a sliding door element, or, for one of them, a panel element constituting the bottom of the cabinet.
• the internal faces of said walls are mutually parallel and with the median wall 16d while the external face of the wall I4d, which extends the wall 5d has a concave curve extending that of the said face. It is thus formed, in the vicinity of the extreme edge of the wall 14d, a reinforcing edge 18d of thickness greater than that of its base situated at the level of the wall 4d while externally maintaining the same appearance as that of the external face of wall 5 of FIG. 1.
• the wing 10d is carried at the base of the extension 15d of the wall 3d in a similar manner to the wing 10 of the section A (FIG. 1).
• the profile E is similar in constitution to the profile D but it differs in that the wing 10e is carried by the wall 3e in the middle of the total height of said wall and its extension 15th, as in the profile B of Figure 2 and for the same purpose.
• the main body 2f of the profile F is reduced to a height corresponding approximately to the outside diameter of the tubular element 7f and it carries on either side and transversely to the wing 10f respectively two groups of extended walls 14f, 15f and two middle walls 16f of the same constitution as the walls 14d, 15d, 16d of FIG. 4. It is clear that the play of the six profiles which have just been described authorizes the constitution of a very large number combinations, some of which will be briefly described below.
• the side panels 20 are interconnected by profiles according to the invention, which are screwed into the elements 7 to 7f by screws such as 11 which pass through suitable milled openings formed in said panels.
• FIG. 9 highlights in particular the way in which the fixing screw 11 passes through the panel 40 and is screwed into the tubular element 7, the corresponding profile 2 of type A having undergone an axial cut on its straight part to highlight this arrangement.
• Figure 10 shows, in top view, a set of two pieces of furniture according to the invention, the one on the right is only partially shown. It should be understood that these pieces of furniture are similar in structure to that of FIG. 7, with installation. or not doors such as 29, 30, 39 and use of profiles of the type C shown in FIG. 3 possibly modified in that they can comprise one or two wings such as 10c arranged not at the lower part of the inner wall of the profiled, but on intermediate generators of said wall.
• the cabinet on the left 50 has the side panels 53 and 65 and the cabinet on the right 51 has the panel 52 and the corresponding panel which faces it and is not visible in the drawing.
• These side panels are joined .two to two by the profiles forming crosspieces according to the invention, such as 69 which have the transverse wings such as 71 which support the plates 70 of which only the upper plate is visible in the drawing.
• the profiles 69 are fixed to the side panels by the tapped screws 72 whose heads 72a are embedded in the thickness of said panels.
• the two pieces of furniture 50, 51 are joined by the screws 62, here constituted by simple threaded rods which cooperate with the blind nuts 63 and pass through the holes 66 made in the panels.
• the holes 66 are drilled in such a way that they come to tangent the extreme edge of the median wings 54, 55 of the profiles.
• the T sections 57 which interest the rear part of the furniture assembly have a transverse wing 59 which constitutes one of the wings of a U-shaped gutter whose two end wings 59, 59a, have two ribs 73 facing each other. one from the other, these ribs are intended for fixing, for example electrical connection elements such as 67, intended for supplying electronic devices housed on the shelves of the furniture assembly.
• the fixing is ensured by pinching the ribs 73 by screws 74 cooperating with square nuts 75 which bear on one of their sides, against the wings 59, 59a.
• said U-shaped gutters constitute passage and guide elements of the conductive cables such as 68 which lead to the electrical connection elements 67.
