Abstract

The invention is in relation to hidden holes or slots behind the outer surface of furniture elements, thus improving the furniture esthetics. It give the possibility to the manufacturer to reduce the number of furniture elements without reducing their applications. The holes or slots may be visible by simple pressing and subsequent collapse of the said outer surface.

Description

METHODS FOR THE CONSTRUCTION OF INVISIBLE HOLES-FISSURES AND THEIR FINDING, IN FURNITURE ELEMENTS AND ELEMENTS OF

PLACE SEPARATION.

The invention is reported to methods for the constuction of invisible holes-fissures, in furniture elements and elements of place separation and the manner of their

finding.

Furniture elements are all the parts of the piece of funiture, before their adjusting from the constructor or the cunsumer to present the complete piece of furniture

(in its totality).

Elements of place separation are pieces of various

materials, with which,adjusted or not, we divise the inner places of residences, offices, sites of works etc. to more or less. They are also used for tike diminution of these places (false-roofs). Furthermore, since the separation

(division) elements of the place constitute furniture, they are called furniture elements.

The creation of the invisible holes and fissures is

managed mainly in two ways:

I) They are created before the furniture elements are lined or painted, afterwards the holes and the fissures remain empty and they are covered of filled with a foamy or other material (for examble: polyurethane), when their size and their form create a problem of solidity to the lining or when the furniture element is not covered with an other material, but it is painted. (Fig.I).

2) They are created with the joining of two furniture- elements which from their inner side, where they are

joined, are perforated in a depth slightly less than their thickness, so that from their exterior side at the point of the hole or the fissure, there is only a thin surface from the material of the furniture-element left. The

thickness of the furniture-element is fixed from the total of the thickness of the two joined furniture-elements. (Fig.2)

Naturally, it is possible that both the ways which have been mentioned above can be used for the creation of

invisible-holes or fissures, in one furniture-element which is perforated or engraved according to the decribed second way so that its perforated side to be covered or painted according to the first decribed way.

With a small pressure on the point of the invisible holes or fissures, the lining or the painting or the thin surface of the furniture-element which has been remained retreats (breaks), the hole is uncovered and the mechanism is

adjusted to it, the part, the screw etc., so that an element (for example a door with its hinge) or any connection for its mounting, can be adjusted to the piece of furniture etc.

The materials which are usually used today for the

contruction of the furniture-element are board-corpuscules, hardboards, M.D.F., bar-boards, ply-woods, pressed polyure- thane or paper-mass, plastic sheets and others, in a covered form or not and, naturally, the wood.

The materials which are used for their covering are: thin sheet from wood (veneer), cartomelamine, plastic carton or metallic lining (tapestry) and others. Naturally many materials like the wood, the plastic sheets and others, is not necessary to be covered or painted, but they remain with their initial surface.

The furniture-elements are generally in a pre-constructed form. They usually consitute parts of dissolved furnitures, they are perforated or engraved in the desired points and with various mechanisms or parts which are adjusted to these holes or fissures, they are mounted (libraries, shelves, compounds, bath furnitures, office furnitures, furnitures of kitchen and other). But they have a basic DEFECT. The pre-constructed holes or fissures which are not used in the mounting are visible and, thus, they attenuate the furniture esthetically, as a result the constructors avoid the unnecessary perforations or engraves, but the

"capacity" of the furniture-elements to more applications is also decreased.

This invention,as described, has as a purpose the

dissolution of this defect. With the creation of as many holes or fissures as wants, it gives to the constructor the possibility, to ameliorate the AESTHETICS of his furniture and to DECREASE THE NUMBER OF THE PIECES in his production range, without decreasing but INCREASING THE "CAPACITY" OF THE FURNITURE-ELEMENTS TO MORE APPLICATIONS.

An application manner of the invention is described below with references to the figures which explain a particular materialization, whereº

In the figure 3 there are 4 perspective views of perforated stanchions (lateral) of one pre-constructed dissolved library. Their dimensions are the same.

The first stanchion is perforated along of its (right) view, to two straight lines, parallel to its two (height) sides, to the points I_I,I₂,I₃,....I_n and 2_I,2₂,2₃,....2_n.

The second and the third stanchions, are perforated both from their two views on the points 3_I,3₂,3₃,....3_n. and 4_I,h₂,4₃,....4_n in one (left) view, 5_I,5₂,5₃,....5_n and 6_I,6₂,6₃,....6_n in the other (right) view the second,

7_I,7₂,7₃,....7_n. and 8_I,8₂,8₃,....8_n, to the one view,

9_I,9₂,9₃,....9_n and I0_I,I0₂,I0₃,....I0_n in the other view the third.

The forth stanchion is perforated only in its one (left) view in the points II_I,II₂,II₃,....II_n and I2_I,I2₂,I2₃,.. ..I2_n.

In the figure 4 there are I2 perspective views of shelves from which the I3, I4, I5, I6, 2I, 22, 23, 24 are of smaller dimension than I7, I8, I9, 20, and 3 perspective views, of rear connections of the furniture support (they support diagonally the furniture) 25, 26, 27.

The existence of the perforations in the stanchions has as a purpose to give the consumer the possibility to settle the shelves to the height he wants and parallely the possibility to change posterioly himself the form and the

function of his library, by changing the positions of the shelves and of the stanchions.

These shelves are spined at the desired points to the stanchions by connections and they present ( figure 5) the mounted preconstructed library.

But the basic defect ( figure 5) is that the unused holes in the stanchions are VISIBLE.

Using this invention in a respective construction, although the holes will exist behind the covering or the painting or the thin surface in the hole points, THEY SHALL NOT BE VISIBLE.

An other amelioration in the construction is that although the constructor has three forms of stanchions, but or the same dimension in his production, that is one perforated in the left view, one in the right and two in both the views, he could have ONLY ONE, using in all the cases, one of the two middle stanchions.

The reason that the constructor has avoided to use the middle stanchions in all the four positions is to avoid the apearance of the perforations on the right and the left side of the library. According to this invention this case does not exist since all the holes ARE INVISIBLE. He could create more of them,ameliorating in this way the "capacities" and the function, of his piece of furniture, because since in the first construction (Figure 5) the extension to the left and to the right is impossible because the holes do not exist, in the second case

(Figure 6) the extension is possible, by the addition of new stanchions, because the holes on the right and the left of the library exist but they are not visible.

The figure 7 is a perspective view of a part of the piece of furniture which appeara in the previous figure 6.

Here are presented the cutting surface (frames) of the stanchion which are connected with the self in the place

28 of the furniture.

The constructors usually cover the cutting surfaces (end- grained wood) of the furniture-elements: I)With thin tapes of thin sheet from wood (veneer), PVC and other, in the cheap constructions, and 2) wood bands, plastic or PVC, 8 to 30 mm thick in the most resistent and dearest.

Naturally the constructor must construct two similar pieces furniture to succeede in the both the cases, the cheap and the expensive one.

With this invention, creating invisible holes or furthermore, fissures in the cutting points of the furniture- elements and covering with the material of the first case, the consumer is given the possibility to add to the same piece of furniture whathe wants with the help of wooden or plastic, divibed or not holdfasts, bands of wood, plastic or PVC, of various forms and colours (Figure 8).

Thus, the "capasity" of the furniture-elements is increased for more forms and the production of the constructor (range) is decreased from two to one furniture.

The discovery of the above described invisible holes or fissures is effected in many ways. The most usual is the utilization of a copy of the furniture-element on a paper or plastic (patron), where the positions of the holes and the fissures are marked.

The discovery is also obtained by the utilization of the dimensions of a design under the scale.

An complete application of the creation of many-compund furnitures with furniture-elements perforated invisibly, of fixed dimensions, industrially applicable, is described below with references to designs. These applications cover all the modern places, professional, residence e.t.c.

Today similar applications cover only one or a few of these places, e.g. only the kitchen or only the sitting- room etc. because of the speculiarity of the used dimensions from place to place and of course, there is always the problem of a not elegant appearance and the unused holes in the created combinations.

Certainly the way by which we work on simiral applications nowdays differs. The furniture-elements instead of being created after the parcelling out of great covered or painted pieces (for examle simple sheet of chip-board or MDF) and after-wards they are covered or painted.

This construction way has already been industrially performed in the described application.

It is characteristic of these described furniture-elements that they can be used in many various posisions in one compound furniture, as stanchions, as shelves, as connections of diagonal support and other, also because of their perforations in the frames they can be connected between themeselves with joints or holdfasts, in the width and the height, giving that way the possibility of a many dimensions creation, in height and depth, to the pieces of furnitures which are under being combined. (Figure IO)

By using auxiliary furniture-elements, as doors, drawers, rears and other which are easily adjusted with hinges, mechanisms and connections in the existing perforations, with the appropriate combinations endless forms of compoud furniture can be created, for examle, compounds, libraries, shelves, cumpboards, kitchen cupboards and benches, drawers, offices, drawing tables, small-tables, beds e.t.c.

The great number of applications is due to the fact that the furnityre-elements are perforated in many points,

increasing their "capasity" so that the same elements can be used in many positions, decreasing for the same reason the number of the used types of furniture-elements in one

construction.

Naturally, the many perforations are not visible and thus they do not influence the aesthetic of the construction.

The furniture-elements of this application are perforated on parallel series of holes 96 mm the one from the other (Designs I3 to I7) at a distance of 32 mm from hole to hole (from center to center). The first line is of 27 mm from the left side of the furniture-element and the last 27 mm from its right side. The first, and the last holes begin I6 mm from their up and down side.

The diameter of the first and the last hole of each line (range) is I0 mm. (They could be 5 mm), since the balance intermediators 5 mm.

Their frames are also perforated, each 96 mm from hole to hole of diameter I0 mm and depth at least I2 mm, with begining and end in height 48 mm(96:2) and in length 27 mm.

The dimensions of these furniture-elements start from

I50 mm (27+96+27) in width, increasing at 96 mm dimension from dimension until 534 mm (27+480+27) and from 288 mm

(96X3) in height increasing in 96 mm up to II52 mm.

5 dimensions in width and I0 in height, that is dimensions total (5XI0) 50. (Designs from I3 to I7).

The great difference in the number of the used furniture- elements between the above described library (Figure 5 and 6) and of one library constructed with furniture-elements of the described application (Figure 9)is presented below.

Let us suppose that the dimensions of the library

(Figures 5 and 6) is of height I63 centimeters, depth 44 centimeters, the small opening of shelf 67 centimeters and the greate 96 centimeters, we observe that the constructor needs 7 various furniture-elements in order to create it.

That is three kinds of stanchions with different perforations two shelves with different dimensions and two connections with different dimensions.

In a respective construction with furniture-elements of the described application (Figure 9) we need only 2. The height of the stanchions is obtained with the settlement of two furniture-elements the one on the other, to say of 960X438 and of 672X438, for shelves we use the same as well as for the connections of diagonal support.

It is estimated that in order to obdain a PART of the applications which are obtained with the described application of the 50 furniture-elements, without the technics of the invisible holes, the constructor must use. more than 500 different.items of furniture-elements, without even in this way to avoid the visible perforations.

An other group of the described application, the named form elements are invisibly perforated. With the many perforations we are given the possibility to use these furniture- elements in many positions. (Designs from I8 to 22).

These are peximetrically perforated in hole series of diameter of I0 mm at a distance of 32 mm from hole to hole (from their center) with beginning and end 30,5 mm (32-I,5 air) from the side of the furniture-element and distance of I4,5 mm (I6-I,5 air) the hole series from the side of the furniture-element. In these perforations the laterals of drawers and also connections are adjusted, so that they can be used as shelves divisions or stable frontages. (Figure II and I2) Mechanisms of retardation are adjusted when these are used as doors which open either up or down. (Figure I2) These furniture-elements are perforated in two points on their left side with a hole diameter of 26 mm at a distance of the hole center from the left side I8,5 mm and 78,5 mm from the uper or down side.

In these two perforations hinges are adjusted (Figure I2) so that these furniture-elements can be also used as doors which open right or left, up or down.

They are also perforated in other points where handles or door handles of various dimensions, locks and other components are settled.

The dimensions of these furniture-elements begin from

93 mm (96-3) increasing in width from 96 mm to 573 mm (576-3) and from285 mm (288-3) in height increasing in 96 mm up to II49 mm (II52-3).

6 dimensions inwidth and I0 in height, total (6XI0) 60.

From the above mentioned dimensions 6, which happen to be equal, must be deducted 6, so 54 are left.

It is estimated that in order to obtain the number of applications which can be obtained with the 54 elements of form which have been described, in combination with the whole application, the constructor must use more than 200 various and different furniture-elements (doors, doors upper, doors down, drawers frontages etc.) in .order to avoid the visible perforations.

In the described application there are also the auxiliary elements which are the rear elements the bases and the wood band which with divided plastic fuses are adjusted to the frontage (frames) of the basical elements (of the laterals or of the shelves) and give various from to the piece of furniture under mounting.

The components referred in the figures II and I2 are some of those which can be adjusted to the present application with the utilization of the already existing invisible perforations and are already in the market.-
