Titles process to manufacture τοη duroh profile tubes assembled furniture · Möbelstüoke following these procedures

The invention has a method for producing furniture for an object which are held together by profile tubes. In the same way it has a profile element or ^M profile "of any length for an object, which is intended in particular for the assembly of furniture that has at least two cross winds" that are connected by two or more transverse walls · It also applies to the piece of furniture · itself, which according to the process are produced

It is known to manufacture furniture parts by " Two side walls are connected by cross members, which are completed by angle attachments, which are generally formed by a rear wall or by spars that are diagonal are generally arranged at the rear of the piece of furniture.

This embodiment has the disadvantage that you can resort to a back wall, for example, except the large one Dimension leads to the creation of a formidable package when the piece of furniture is paoed for sale become nut · In addition, it cannot be prevented that special parts are used to support the floors whichever the intermediate boards form, nooh the need for stiffening elements can be avoided

to provide the stalls mentioned in their longitudinal direction.

The arrangement of spars, which form a diagonal bracing, has similar disadvantages and. is hinaas unattractive about it.

The method according to the invention eliminates these disadvantages; it allows to use profiles of special cross-section, which have a traverse and elbows for the cross winds form and stiffening elements for the floors, and it enables the manufacture of furniture that are new in construction themselves and that can be joined side by side to make up of two or more lends Furniture elements to form existing units

The profiles are made in a known manner in parts of great length and generally consist of one borne and soft metal alloy, for example from an aluminum alloy, or at least consist of a relatively strong plastic. These elements of great length have a constant ProSil (or constant cross-sectional shape) and are later in parts of the required length has been cut

The profile according to the invention is designed in more detail with a view to a mounting and connecting element to create a traverse between the two side walls of a piece of furniture and a support element for one or forms several intermediate floors that serve to carry objects to be accommodated.

For this purpose, the extruded profile according to the invention has a tubular main body and is notable for the fact that, on the one hand, it has at least one tubular Has longitudinal element with an approximately circular inner cross-section, which has at least one inner surface of its loin is firmly connected and is intended to be a screw

receive for attachment to one side of a piece of furniture, and on the other hand has at least one flange which is arranged so as to be transversely projecting over one of its outer walls and which is intended to keep a ^H öbeltei}., such as a floor, or support, the tubular element and the said flange being extruded in the same way with the profile itself «

The cross section of the profile is preferably closely related to that of a rectangle, which in the direction transverse to the protruding flange is elongated and the ends of which are cut at right angles to the extrusion direction. This design makes it possible, by simply tightening two corresponding opening-crossing screws, which are each arranged in two opposing walls are and engage the two previously threaded ends of the tubular member by supporting the Walls against the support polygon, which is from the end of the actual tubular body of the profile and that to it transverse flange is formed to achieve a very good parallelism between the mentioned walls « The piece of furniture, which has at least four profiles of the type defined above, which are in the same manner in the vicinity of the Four Eoken are attached to each wall, thus forming a completely rigid furniture parallelepiped.

Furthermore, the profiles are arranged in such a way that the transverse flanges are directed in pairs towards one another and in lie on the same level in such a way that they are governed by a group of two corresponding profiles carry·

The floors can, for example, after the assembly of the Furniture body can be brought into position, which, as yet will have to be explained in more detail, consists of the two walls connected by the profiles. You are in this

However, certain panels can also have a deep groove on each longitudinal edge, which is intended for the Take up the flange of the corresponding profile. In such a case, the floor will be damaged when assembling the The corpus is brought into position and thus finally locked by this.This design is particularly essential if you want to ensure a constant distance between two floors, which even vertical furniture parts, such as partition walls or rows of inflexible rods, have to lock the task hold books or recorded records in a vertical position, for example.

Finally, two or more furniture parts assembled in this way can be placed side by side by adding End profiles are connected to each other, which the joints between two pieces of furniture or partition walls on Cover the end.

The invention will be well understood upon reading the following description of some embodiments that include Reference is made to the accompanying drawings in which:

FIGS. 1 through 6 are cross-sections of six different embodiments of FIG Profiles according to the invention,

Fig. 10 is a plan view of two pieces of furniture according to the invention, which are connected to each other standing side by side with the interposition of end profiles and with a boundary wall attached to one end

In FIGS. 1 to 6, parts with the same function are denoted by the same reference numerals, whatever their mutual position or possibly their number like.

In Fig. 1, the profile A consists of a light aluminum alloy and is produced in a manner known per se by extruding the metal through a suitable drawing die; it shows:

a tubular main body 2 of elongated cross-section, the small flat walls 4 and 6 thereof stand perpendicular to a flat wall 3 of much greater length, while the fourth wall 5, which is the Wall 3 corresponds to, is concave,

- An intermediate wall 9 which connects the opposing inner surfaces of the profile 3 »5 and carries a tubular element 7, the internal cross-section of which is approximately circular and for reasons has a longitudinal cut 8 for easier production compared to the production of the extrusion mouthpiece,

a flange 10 carried by the wall 3 and projects across the outer surface of the latter.

The tubular element 7 is threaded on both sides so that there are screws 11 for fastening the side walls of the piece of furniture.

The flange 10 is used to receive and support a the longitudinal edges of a board or floor 12, the opposite edge of which is supported by the flange of an analog and inversely directed profile, which in the same , Way is arranged between the two side walls of the assembled piece of furniture, as indicated in the introduction was explained.

In addition, the flange contributes with its outer edge to the support polygon of the profile on the associated wall form and so the stability or cohesion of the connection in the direction of the corresponding small sides 4 and 6 of the main body 2 to enlarge.

In Fig. 2, profile B has a tubular main body 2 of similar design to profile A, which in the same way carries a tubular element 7 on the inner surfaces of its walls. However, profile B differs from profile A in that the flange 10b, which corresponds functionally to the flange 10, there in the middle of the Height of the wall 3b is connected.

This embodiment makes it possible to place a base 12b of suitable thickness on the flange 10b in such a way that its surface is in the immediate vicinity of surface 6 of profile B. This design, which is the same as that of FIG. 5, enables it also, as shown in the latter figure,

to carry a bottom 12e, In which a deep longitudinal groove 13e arranged 1st, which has such dimensions that the flange 10b or 1Oe can possibly be absorbed there under the action of force.

In Figure 3, the profile C has the flange at its base 10c carries a relatively much greater height than the profile A} it consequently carries two longitudinal tube elements 7c, which are symmetrically distributed on both sides of the middle section of the profile when viewed in section la. Such a profile has the advantage that, for example, in the Height of the upper shelf and on the front of the piece of furniture an edge panel can be attached, which makes it possible to cover the lower part of a device, for example a reading table for long-playing records, which one wishes to conceal.

Xn Fig, 4, the profile D has a relatively small, tubular main body 2d, the wall 4d of which, functionally corresponds to the wall 4 of FIG carries tubular longitudinal element 7d. In this embodiment the long walls 3d, 5d are above the small wall 4d extended in such a way that they form two walls I4d, 15d, which together with a central wall 16d extending from the Wall 5d is carried in the middle and has the same direction and extent as the first two, two grooves 17d, which are intended to either each one To take up an element of a sliding door or to take up a wall part with one of them, which forms the rear wall of the piece of furniture, as can still be seen in FIG.

It is to be noted that the inner surfaces of the aforementioned walls are parallel to each other and with the central wall I6d, while the outer surface of the wall I4d, which extends the wall 5d, has a concave curvature, which extends that of the said surface. As a result, in the vicinity of the

Outer edge of the wall 14d formed a reinforcing edge 18d, the thickness of which is greater than the thickness of its base, which is is at the level of the wall 4d, which outwardly has the same appearance as the outer surface of the wall 5 towards Fig. 1.

In this embodiment, the flange 10d is on the base carried by the extension 15d, in a manner similar to the flange 10 of the profile A (Fig. 1).

In Fig. 5, the profile E has a similar design to the profile D, but differs from this in that the flange 10e of the wall 3e is located in the middle of the total height of this wall and its extension 15e, as is the case in profile B of FIG. 2 for the same purpose.

In Fig. 6, the main body 2f of the profile F is reduced to a height which almost corresponds to the outer diameter of the tubular element 7f and carries the main body on both sides and across the flange 10f two groups each of wall extensions I4f, 15f and two middle walls 16f of the same design as the walls I4d, 15d and I6d of the Fig. 4.

It is evident that the set of six profiles described allows the manufacture of a very large number of Combinations possible, some of which are briefly described below.

In Fig. 7, the side walls 20 are connected to one another by profiles according to the invention, which are screwed together in the elements 7 to 7f, for example by means of screws 11, which pass through matching, milled openings arranged in the walls mentioned _o One notices two in the lower part Profiles 21 and 22, both of which are of the type

E, which carry the lower base 23 on their flanges 1Oe, above the floor 23 and at a certain distance therefrom, a floor 24 on its front surface is related to one another the profile 21 is held by an inverted profile 25 of the type E, while on its rear side it is held by a profile 26 of the type F is held. The flanges 10e, 10f of the profiles 25 and 26 engage in recesses, such as 13e, of corresponding ones Dimensions, which are arranged in the longitudinal edges of the floor. A rear wall 27 is in the grooves 17d of the Profiles 22 and 26 used after a compensation piece 28 was used, for example, from a matching profile element. On the front of the piece of furniture are in the corresponding grooves 17d of Profiles 21 and 25 each have a sliding door element in the same way 29 and 30 are used, which also rest on compensating pieces that are identical to the compensating pieces 28 are.

In this way, a lower compartment is formed, the front by the sliding doors 29 and 30 between the floors 23 and 24 is to be opened, the mutual distance due to the profiles used to support the lower floor from Type E and F is invariable, the support flanges 1Oe and 1Of engage in the longitudinal grooves 13e and 13f. This Design allows in blind holes 31 and 32, which are arranged in the depth of the two floors considered, To bring rows of metal rods 33 in position and to hold, which are brought into position by a simple bend or simply through there in this position their weight remain, the blind holes 32 have such a great depth that the rods are easily inserted from the side can be and then caused to settle on the bottom of the blind holes 31 by gravity.

Above the floor 24, the floor 33 is arranged, which by the profile 34 of the type C and by the profile 35 from

The rear wall 36 is made in the same way brought in Stelliing and held like the wall 27 while Pivoting elements 37 pivotably pass through the lower and upper wall of the profiles 25 and 34 and each one on the pivot pin Have fixed rail in which a pivoting door element 39 is held immovable by a screw 38.

8 and 9 show a simplified piece of furniture, the design of which is similar to that of the piece of furniture according to FIG is, in which the profiles 41 to 44 hold the two side walls 40 and the floors 45 and 46 carry. The piece of furniture rests on the floor with pivotable rollers 47, which are pivotably mounted with their axes 48 in shoes 49, which are attached to the underside of the floor 40.

Drawing, however, is not recognizable «, these side walls are connected in pairs by the profiles that form trusses according to the invention, such as the profiles 69, which Have transverse flanges 71, which carry floors 70 of which only the top floor can be seen in the drawing is.

The profiles 69 are on the side walls with threaded screws 72 attached, the heads 72a of which are sunk into the depth of said side walls.

The two pieces of furniture 50 and 51 are connected by the screws 62, which are formed there by simple threaded rods which cooperate with cap nuts 63 and pass through the bores 66 arranged in the side walls.

In order to cover in particular the joint 60 between the walls 52 and 53, two profiles 56 and 57 are provided which are essentially in the shape of a T, the middle legs 54, 55 of which are inserted between the two walls before the nuts 63 are tightened the transverse flange 58, 59 has a width that is exactly equal to the thickness of the two adjacent side walls 52 and 53 increased by the thickness of the central leg 54 and 55, respectively, to the front and rear edges (and possibly the upper edges) of the walls with respect to completely cover for an aesthetically better effect. In the drawing, and because it is so common, the T-shaped profiles of the left-hand part, which will be discussed below, are shown hatched to make their outline clearer, _etc.

It is clear that after tightening the screws and nuts 62 and 63, the profiles 56 and 57 by the screw pressure, which acts on its middle leg via the side walls 52 and 53, are held firmly in position.

It should be noted that the holes 66 are drilled so that they are the outer edge of the central legs 54 and 55 of the profiles touch to avoid possible deformation of the side walls under the screwing pressure of the bolts and nuts 62 and 63 to avoid.

In order, on the one hand, to cover the numerous heads of the fastening screws 72a which appear on the wall 65 and, on the other hand, to give the piece of furniture a balanced appearance, an end wall or end wall 64 is provided in the embodiment shown in FIG Wall 65 and which this with the interposition of two T-shaped profiles, as they have been described further above, covers _β The screws 62 here, however, have a countersunk head 62a which is let into the end wall. To fasten the end wall, four fastening screws 62 can be provided, which are distributed over the wall corners. In the case of furniture of greater height, however, it goes without saying that intermediate screws can also be provided.

The T-shaped profiles 57 that form the rear of the furniture assembly hold, have a transverse flange 59, which forms one of the two legs of a U-shaped channel, the two outer legs 59 and 59a of which have two strips 73 lying opposite one another. These bars serve For example, for fastening electrical connection parts 67, which are used to supply electronic devices, which are placed on the floors of the furniture assembly. The attachment is made by pinching this Last secured with the help of screws 74, which cooperate with square nuts 75, which are connected to a support their edges against the legs 59 and 59a.

Last but not least, it should be noted that the U-shaped grooves form passage and guide elements for line cables 68, which extend as far as the electrical connection elements 67 ₀
