Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to tubular steel sections used in the assembly and manufacture of furniture. The tubular steel sections of the present invention have various lengths and shapes. The present specification also discloses an assembled furniture including at least two side panels connected to two or a plurality of horizontal panels using these sections, and a method for manufacturing the same.

(Prior art) Furniture components are manufactured by connecting two side panels using a cross-branch component along with an angled component formed by a frame component and a back panel provided diagonally behind the furniture. This is known.

This method has the disadvantage that, for example, when furniture members must be packaged for sale, the entire backing board becomes large in size, making packaging difficult. Furthermore, this method requires the separate provision of support members for the shelves forming the intermediate tray and members for enhancing the support of the shelves along their length.

Arranging frame members forming diagonal cross axes presents similar drawbacks and further impairs aesthetics.

(Problems to be Solved by the Invention) Therefore, an object of the present invention is to provide a shaped steel that can efficiently connect furniture members for assembly so that each furniture member does not have to be large, and that supports shelf boards. The object of the present invention is to solve the above-mentioned drawbacks of the prior art by providing a section steel that can also be used as a member or the like.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a tubular section steel for constructing a framework of furniture, which is made by extrusion forming, the main tubular section being and at least one elongate tubular member having a substantially C-shaped circular internal cross-section, said tubular member being connected by the shank of a partition connecting two opposing walls of the section to each other. and is adapted to receive screws at each end for attaching the section onto the panel plate of the framework by means of fixing screws, said main tubular portion being substantially fixed to the wall. The blade has at least one wing that is provided to protrude laterally from the tubular member and the wing that is capable of supporting a furniture member such as a shelf board by gravity, A piece is a section that is extruded together as a whole, and this extruded section is cut along a plane perpendicular to its length with the wing pieces at each end. There is provided a section steel characterized in that the curved end faces form a polygon that supports the section steel on a corresponding panel plate.

Shapes are generally manufactured as large lengths of light plastic metal alloys, such as aluminum alloys, or of relatively hard plastic materials, the large lengths having a defined contour or cross-section. It has a shape and is later cut into pieces of the required length.

The steel section according to the invention is particularly designed to constitute an assembly connection member forming a crosspiece between two side panels of furniture, or a support member for one or more intermediate shelves supporting objects to be accommodated. has been done.

The section of the steel section is preferably close to a rectangular section elongated transversely to the direction in which the protruding winglets extend, and both ends of the section steel are cut at right angles to the direction of extrusion. In this way, two screws can simply be inserted through openings formed in two opposing panel plates and threaded into the two ends of the pre-threaded tubular member. , it is possible to maintain good parallelism between the two panels. This is because the tubular main portion, the tubular member, and the end faces of the wings extending laterally from the tubular member form a flared support polygon that abuts the panel board.

The furniture is constructed as a rigid parallelepiped piece of furniture, including at least four sections of the type described above secured adjacent to the four corners of each panel board in the same manner as described above.

Furthermore, each section steel may be provided with wings extending in the transverse direction in pairs so as to face each other, so that each of the two corresponding wing sections of the section steel supports one shelf board. .

Further, the shelves can be installed after, for example, assembling the framework of the furniture, which is made up of two panel boards joined together using shaped steel, as described above. In this case, the shelves will simply be placed on the oppositely arranged wings.

However, some of the shelves have deep slots on each of their longitudinal edges that accommodate corresponding section steel wings. In this case, the shelves are installed during assembly of the framework and become integrated within the framework. This configuration is especially necessary when it is desired to keep the distance between the two shelves constant, and the two shelves can themselves be used as part of a piece of furniture, such as a bulkhead or rigid wire partition, for example to keep books or records in a vertical position. Maintain vertical members installed.

Two or more furniture elements constructed in this way can be joined together in juxtaposition by using finished sections that hide the joints between the two pieces of furniture or by adding finished end panels. Something happens.

The invention will be better understood from the description of some embodiments with reference to the accompanying drawings, in which: FIG.

In Figures 1 to 6, elements with the same function are given the same reference numerals, regardless of their relative position or number.

In FIG. 1, the section steel A is made of an aluminum light alloy obtained by a known method of metal extrusion through a suitable die, and has a large flat wall 3.

The tubular member 7 is internally threaded at both ends and adapted to accommodate screws 11 for assembling furniture side panels.

The wings 10 are adapted to receive or support one of the longitudinal edges of the tray or shelf 12;
The opposite longitudinal edge is supported by a section steel wing located opposite the section shown.

Furthermore, the wing pieces constitute a polygon with their end faces that support the sections on the corresponding side plates, and the main tubular part 2
This serves to improve the stability and bondability of the assembly in the direction corresponding to the small flat walls 4, 6.

In FIG. 2, section B has a main tubular section 2 of similar construction to section A, which section 2 likewise supports a tubular member 7 on the inner surface of its wall. However, in the steel section B, the blade 10b is functionally similar to the blade 10, but differs in its position.
That is, it differs from the section steel A in that it is supported at the middle of the height of the wall 3b.

With this positioning of the wing piece 10b, it is possible to provide on the wing piece 10b a shelf plate 12 of an appropriate thickness such that its upper surface is immediately adjacent to the upper wall 6 of the section steel B. Wings 10b can also support shelves as shown in FIG. For this purpose, a deep slot 13e is provided in the shelf plate (FIG. 5) of a size that allows the wing piece 10b or 10e to fit snugly into it.

In FIG. 3, the section steel C supporting the wing piece 10c at the bottom is higher than the section steel A and therefore supports the two tubular members 7c in two symmetrical positions with respect to the central part of the section section. ing. Such sections can be used, for example, at the level of the uppermost shelf, or on the front of a piece of furniture, as a skirt member that can cover the lower part of a device, such as an LP record pick-up stand, that you wish to hide. It has the advantage of being able to form

In FIG. 4, the section D has a relatively small main tubular section 2d, whose wall 4d is similar to the wall 4 of FIG.
, but directly supports the tubular member 7d. In this example, large walls 3d, 5d
extends beyond the small wall 4d to form two walls 14d and 1
5d, these walls 14d and 15d are supported in the middle by the wall 5d, and the two walls 14
With central wall 16d extending in the same direction as d and 15d, sliding doors 29, 30 are provided as shown in FIG.
Alternatively, two grooves 17d are formed for accommodating panel members constituting the back plate 27 of the furniture.

The inner surface of the walls 14d and 15d is the central wall 16d.
The outer surface of the wall 14d, which is an extension of the wall 5d, has a concave curve that is an extension of the concave curve of the surface of the wall 5d. Therefore, wall 1
At the edge of wall 4d, a reinforcing edge 18 which is thicker than the thickness of wall 14d located at the height of wall 4d maintains wall 14 outwardly, similar to the outer surface of wall 5 in FIG.
It is equipped with d.

In this embodiment, the blade 10d is a blade 1 made of section steel A.
Similarly to 0 (Fig. 1), the extension part 15 of the wall 3d is
It is supported on the bottom of d.

In FIG. 5, the section E has the same structure as the section D, but the blade 10e is connected to the wall 3e and its extension wall 15e for the same purpose as in the section B of FIG. It differs from section steel D in that it is supported at the center of the entire height.

In FIG. 6, the main tubular portion 2f of the section steel F is reduced to a height approximately corresponding to the outer diameter of the tubular member 7f, and extension walls 14f, 15f and Two groups of central walls 16f are supported laterally on each side of wing 10f.

The set of six sections described here can be configured in a very large number of combinations, some of which will be briefly explained below as a method for manufacturing assembled furniture.

In FIG. 7, the side plates 20 are connected to each other by steel sections according to the invention, and the side plates are fastened to the tubular members 7 to 7f by screws such as 11 passing through suitable perforations in the side plates. . At the bottom are two steel sections 21, both of which are E-shaped (FIG. 5) and which support a lower shelf board 23 by their wings 10e.
22 are provided. Above and at a distance from the shelf 23, the shelf 24 is supported in front by a section 25 of E-shape inverted with respect to the section 21, while a section 26 of F-shape (FIG. 6) It is supported at the rear by. The wings 10e, 10f for the sections 25, 26 engage in correspondingly sized slots, such as 13e, provided in the longitudinal edges of the shelves.
The back plate 27 engages in the grooves 17d of the sections 22 and 26, with a thickness key 28, which is constructed of a suitable section steel member, for example, installed in advance. The front part of the furniture has the same thickness as the key 28. Sliding doors 29, 30, which are also located on the key, similarly engage in the grooves 17d of the individual sections 21, 25.

Shelf board 23 whose mutual distance is fixed because E-shaped or F-shaped section steel in which wing pieces 10e, 10f are engaged in longitudinal grooves 13e, 13f is used for supporting the lower shelf board. and 24, sliding door 29,
30 is configured with an inwardly extending lower compartment. In this configuration, metal such as 33 is installed by simply bending into blind holes 31, 32 provided through the thickness of the two opposing shelves, or is held in position simply by its weight. It is possible to install and maintain a row of pieces, the depth of the blind hole 32 being such that the metal piece is introduced diagonally and lightly and then guided by weight to be located at the bottom of the blind hole 31. That's how deep it is.

Above the shelf board 24, a shelf board 33 is provided which is maintained by a C-shaped steel section 34 and a D-shaped section steel 35.
The back plate 36 is installed and supported in the same way as the back plate 27, but on the front side, the pivot member 37 is connected to the sections 25 and 3.
It is pivotable through the lower and upper walls opposite to 4 and is provided with an integral groove in which a hinged door 39 is fixed by screws 38.

8 and 9 show a simple piece of furniture similar in construction to that of FIG. 7, in which the section steel 41
44 maintains the two opposing side plates 40 and supports the shelf plates 45 and 46. The furniture is installed on the floor via caster wheels 47 which are provided to pivot within shafts 48 provided in a bottom plate 49 fixed to the bottom of the side panels 40.

FIG. 9 particularly shows how the fixing screw 11 is screwed to the tubular member 7 through the side plate 40', and shows the section steel corresponding to the A-shaped tubular member 2 in axial section in the right part. shows its configuration.

FIG. 10 is a top view of a combination of two pieces of furniture according to the invention, the right side of which is only partially shown. These pieces of furniture have the same structure as the one in Figure 7, and can be installed with or without doors such as 29, 30, and 39, and are made of C-shaped steel as shown in Figure 3. is modified so that it can include one or two wings such as 10c placed on the middle generatrix of the wall rather than at the bottom of the inner wall.

The furniture 50 on the left includes side panels 53 and 65, and the furniture 50 on the right has a side panel 52 and a corresponding side panel opposite thereto that is not visible in the drawing. These side plates are made of two steel sections forming a cross-section according to the invention, such as 69 having wings such as 71 supporting a plurality of shelves 70 of which only the upper shelf is shown in the drawing. are connected together.

The shaped steel 69 is fixed onto the side plate with internal screws 72, with the head 72a embedded in the thick part of the side plate.

The two pieces of furniture 50, 51 are connected by a screw 62, which is a simple screw shaft, which cooperates with a cap knight 63 and passes through a hole provided in the side plate.

In particular for the purpose of shielding the seam 60 existing between the side plates 52, 53, according to the invention a generally T-shaped wing whose central wing 54, 55 engages between the two side plates before tightening the nut 63 is provided. Two steel sections 56, 57
are provided, while the wing pieces 58, 59 are provided with the center wing piece 5.
Two adjacent side plates 52, 53 with a thickness of 4,55
The width is approximately equal to the width plus the thickness of the side plate, and the entire front and rear (sometimes upper) edges of the side panels are covered for aesthetic effect.
In the drawing, the T-shaped steel on the left side is shown with diagonal lines to make its outline easier to understand.

After tightening the screws and nuts 62, 63, the sections 56, 57 are held firmly in place by the tightening force exerted on the center wing via the side plates 52, 53.

In order to avoid unexpected deformation of the side plate under the tightening force of the screws and nuts 62 and 63, the holes 66 are grogged.
Make the edges of the center wing of the section steel tangential.

In the embodiment of FIG. 10, an end or finished side plate 64 of the same thickness as the side plate 65 is used to cover the multiple heads of the fixing screws 72a appearing on the side plate 65 and to provide equilibrium to the furniture. The side plate 65 is covered by inserting two T-beams as described above. However, the screw 62
Here, it is provided with a grooved head 62a which is recessed into the thickness of the finished side plate. The fixing screws 62 to the finished side panels can be divided into the four corner heights of the side panels, but it is clear that in the case of tall furniture other intermediate screws can be provided.

The T-beam 57 associated with the rear part of the furniture assembly has a wing 59 whose two end wings 59, 59a constitute one of the wings of a U-shaped groove with two ribs 73 facing each other. have These ribs are adapted to secure, for example, electrical connection members, such as 67, adapted to power electronic devices housed on the shelves of the furniture assembly. Fixed by wing piece 59,
This is ensured by pinching the rib 73 by means of a screw 74 cooperating with a square nut 75 which supports it by one of its flat faces against 59a.

Further, the U-shaped groove constitutes a path guiding member for a power transmission line such as 68 which joins the electrical connection member 67.

(Effects) According to the shaped steel of the present invention, it is possible to construct furniture by connecting relatively small furniture members of furniture for assembly, so even when packed in a disassembled state, it does not become bulky as in the case of conventional furniture. That's fine. Further, since furniture members such as shelves can be supported, a separate member for supporting shelves, which is conventionally required, can be omitted.
