! Designation: "Process and insert trays for interior decoration of furniture ".

The present invention relates to a method of manufacture of furniture with an inner cladding made by injecting a foamable material with a light outer cladding case is firmly connected.

The use of plastics and soles in the field furniture production, especially for kitchens, is known per se.

The furniture industry, for example, produces all sorts of sorting elements for the kitchen from wooden panels that are made with soaking material based on "melamine", e.g. coated with "du formica".

The manufacture of furniture with components from such panels requires that they coexist within one and the same plant several interdependent systems with different technologies.

One of these plants deals with e.g. Production of support housings (plywood and chipboard), which are covered on one side with plastic sheets or flooring material.

clothes bind.

It should be noted that this support housing is through the Fluctuating humidity warps, which sooner or later has the consequence that the veneers come loose.

In addition, this production brings many different gluing operations, Pressing and drying with it Ee is therefore necessary, to cut these panels to the required dimensions and the operations necessary for finishing perform.

Another focus of production is directed to the work processes that are used to manufacture those furniture parts that are made of non-veneered wood.

When assembling the various components of the Piece of furniture with each other as well as the add-on parts fit together «This piece of furniture has to fit inside with that for its purpose essential accessories, e.g. with suitable supports to hold the shelves on their To hold plata.

Eb is understandable that the time it takes for these operations must be spent, accounts for a significant part of the hours needed to make the furniture, especially if the Assembly takes place in private households.

Since the time for the manual labor is the most significant part of the cost, it is practically impossible to determine the cost price of furniture made in this way reduce.

The production accordingly comprises a whole series of operations of different nature that are difficult to coordinate with one another

109808/0653

and which are poorly suited for large-scale production.

It is true that devices are already known which are provided with a cushion made of foamed plastic inside the crosswinds, but in very specific areas, such as ». in the heating industry (uasherde) or refrigeration industry (refrigerators). Außeruuiii iat be noted that in these devices, the outer walls of which the iäiiuse oilden that the various x'eilen of Geräuäs (^ ui.lmotcr oei refrigerators, burner for gas stove, etc.) ain i "ra _(-er uient necessarily are made of a resistant material.

Most of these devices have the interior limited to a binary set, which is generally used in casting ancestors or is manufactured using the drawing process and which is attached to the Höbel frame with an outer rim.

But when assembling these latter, the pre-expanded, preformed and cut plastic pads the inner walls of the housing attached so that the inside provided for the subsequent fitting of the insert shell Space remains available. This insert tray can be used as light shelves (grid shelves in the refrigerators).

Then there are containers with double walls that delimit a chamber into the interior of which a foamable material is injected that attaches to the chamber walls and a Forms cushion that increases strength.

However, these are mostly thermos flasks, the production of which does not pose any of the many problems, such as they are mentioned above in relation to the furniture industry.

In order to remedy the ills of this industry, the applicant is got the idea to have armored furniture inside

to equip a foamed upholstery and ale inner wall to use against the upholstery insert bowls, as they are used in the devices described above.

For this purpose, the furniture is built from two parts!

- once with an outer overall housing without special strength properties, as it is of a .bauart with one or more frames to accommodate one or more insert shells can and

- on the part with a cast or injected insert Bohale, which is with the for its future Use the necessary accessories.

The assembly consists of placing the insert (s) in the corresponding opening (s) in the housing, to fasten the edge strips of the insert shells on the frame strips of the housing and a foamable material between inject the insert shell and the outer housing.

The invention will be explained in more detail with reference to the accompanying drawings t

Fig. 1 is the perspective view of a piece of furniture with 4 components according to the invention.

Fig. 2 shows a Höbelstück according to the invention, the has a one-piece rigid structure, is open along its entire length and without cross bracing.

Fig. 3 shows the hinge system that is used for fastening the doors.

Fig. 4 represent sections of the various assembly -> ^u * possibilities of insert shells without bent outwards

The housing 10 in fig, I contains 4 adjacent cells, which are bounded at the front by a transverse wood 11 into which the corresponding insert shells 12 are or will be fitted.

In the case of the insole 12a, which is not yet in the housing, are on the three inner sides of the insert shell molded support strips 13 parallel to the reception of the shelf boards arranged, which consist of massive, full plates 18 (Fig.2). The latter are therefore based on 3 sides, which enables that the pressure on the plates to which they are exposed under heavy loads is distributed and the risk of deformation is turned off. ™

In order to arrange the distribution of the shelves inside the furniture as desired, the vertical walls of the insert sofa are provided with a series of support strips that are arranged parallel to one another. In the illustrated embodiment the distance between two strips let as large as the Dioke the shelves and it provides a sliding track 19 is, is inserted into weloh · the shelf and held in it, preventing any tilting of the plate forwards.

An envelope around the entire circumference of the socket 14 (Fig. 1)

m is on the rim of the housing and on the Randver-

aspiration to lie so that the insert can be attached to it

The built-in housing Binsatzsohale 12b with partial lateral cutout, shows filling 15 au · foamed plastic whose attachment is explained below and is intended to fill in the spaces between the housing and the insert and give the necessary resistance au the piece of furniture.

The inner filling 15 takes place duroh foaming a light Resin, e.g. polyurethane! that is what you bring especially to the

109808/0693

Side panels of the housing with openings that allow:

- once a uniform injection of foamable material into the entire room between the insert shell and the housing and

- on the other hand, the air present in this room due to the pressure of the plastic material to drive out.

So you walls have two series of openings: one on the lower part of the wall and the other on the upper part for the purpose the ventilation and also as an overflow in the event of too much filling. As soon as the foamed material is solid, these openings are closed with suitable means.

12o is a built-in insert shell. You can see a metal one Winkelohiene 16, which with the interposition of a bead lets the rim of the Sinsatar sit on the edge of the case.

? ig. Fig. 3 shows the details of the hinge as used to mount the doors P. This hinge system is known per se, so that it is unnecessary to describe it in detail. It enables a lateral shift, which lifts the door when opening Pl, P2 (see arrow 5 ¹ I). The door in the open state P3 is etched face to face on the side edge of the furniture.

In addition, the invisible hinges contribute to the nicer appearance of the piece of furniture.

According to another type of joint construction, Pig. 4, 5 and 6 are used a metal profile 20, 21 or 22, the la section L-shape (21) or U-shape with equal legs (22) or unequal legs (20), on the vertical, the different cells

dividing frame bar attached to 23.

This profile 20, 21 or 22 comes with screws 24- either on the inside in the case of the profile 20 or 21 or in the case of the profile 22 on the face of these frame bars fastened and creates a fastening groove on the cell edge, the opening of which runs against the base of the housing, is equal to the bead of the edge 25 of the insert.

The edge 25 of the insert that extends from the front of the housing is introduced, sits firmly in this groove. The free spaces between the walls and the housing are with foamed material '26 filled.

According to the arrangement in Fig. 4, the fastening screws of the Profile covered by the edge of the insert. In the species the assembly naoh Fig. 4 and 6 is the insert pocket held in place by the foamed material.

A variant of this technique consists in pouring (Form) the seed tray directly into the one provided in the housing Cavities takes place.

This way of making furniture makes it very easy to use housings made of material of small thickness 3ind, the strength and rigidity of which is achieved by injecting a foamed plastic compound which takes place in the cavities between the insert and the housing, and which adheres strongly to the walls of these two elements.

The invention is in no way restricted to the type of embodiment described here, but of course includes all of them Variants a.

on the techniques used up to now.

This simplifies production in a unique way. It only includes:

- the manufacture of a simple housing without any internal accessories, the purpose of which is to to carry and disguise the inset shells,

- the production of ready-to-install insert shells made of plastic material using a casting process Injection or molding under vacuum, outside or directly in the cells,

- a single assembly operation, quick and easy, to complete the two components Unite EU,

- the injection of a foamable resin between the basin and the walls of the cells.

They do not require the various manufacturing stages manifold operations for assembly and final completion, as are common practice, and from this Reasons for using this process can be an economic production in large series.

The furniture produced in this way can be provided with all types of shelves; they let the burden go heavy objects, as they also contribute to the nicer look of the furniture. You are very nervous because of them empty spaces are filled with foamed plastic.

With the internal cladding reduced, they have all the classic advantages of the cast material (easy to maintain, significant color scale, no more blind spots, etc.).

109808/0 6 53

They can also be made from a single cell of large dimensions exist, so that they have a considerable volume and no central cross bracing, for security the strength and stiffening of the housing.

Such a piece of furniture offers a completely free space that is accessible in its entire length without any Operations for special equipment, as is the case with all furniture with toothed racks on which the shelves rest, the case is.

The distance between the support strips can also be greater than the thickness of the boards and the support strips can be continuous or be attached with interruptions to the vertical walls.

Such furniture unite the door parts, which are inherent in an interior design made of plastic, with the possibilities the external design of a normal wooden furniture piece.

In particular, when the outer housing of the furniture from wood panels, formed from plywood or pressed sheets, these materials may be printed or painted veneer plated and it is possible in this way to obtain clientele decorative effects depending on the tastes of the _A.

Due to this technology, it is also possible to create period furniture and to get all the desired decorations by means of decorative strips and decorative grooves.
