Description

The invention is based on the idea of reducing the loss of material in wooden furniture to a minimum determined by the corresponding pacHejpM for sections of each part and part of the product. If it is impossible to achieve this goal in ordinary furniture made from Solid wood parts, the cross sections of which are obviously much larger than those calculated, the need to ensure the strength of the fasteners, the use of plywood, according to the inventor, can provide economic benefits, since the gluing allows bending in various directions, and all plywood, and the manufacture of the I1 cobblestones from it, with interlocking connections, allows them to use reinforcing metal or other gaskets and fasteners, or various types of knots. In the present invention, invented various ways of Vi.pieces for making furniture from fanjbi, in the form of glued plywood boards and plywood strips, straight, curved, twisted and grieved, using various inserts; spacers, lattices and ties and with the introduction for reinforcement of metal or other polrs and gaskets and various nodal fixings.

In FIG. , 2 / and 3 huts reflect a plywood chair in three projects:

FIG. 4 is the same detail of the connection parts (top view); FIG. 5-10 plywood stool in different projections and sections; .fig. 11, 12, 13, 14, 15, 16, 17, and 18 are different options in the device legs and frame; FIG. 19 and 20 are views of a tabletop and an under-table in two projections of FIG. 21, 22 and 30 variant of the chair in side view and its details; FIG. 23, 24, 25, 27, 28, 29 and 32 variants, sections of plywood bars; FIG. 26- about to flax and type of plywood bar; FIG. 31-method of making a lattice of plywood strips.

The chair described by way of example is made of narrow strips of glued laminated furniture — birch, / alder, aspen, etc. For the formation of individual parts of the chair-legs, seat frames, backrests — several such strips are glued together in one bar. Each knuckle-up consists of two such bars: side-G, 2-2 and additional front and rear 3--3, 4-4 (fig.I, 2 and 4). The side bars are set obliquely to one another and slightly curved, with their lower ends retracting from the chair and from the vertical plane and passing through the sides of the seat frame. Additional bars and 4-H are connected to the main screws B-6 below (Fig. 2) and on the glue, and their upper ends are fixed in the front and rear

parts of the seat frame. To enable one-side fastening of these ends at the top with the frame of the seat, as well as for their bending, the bolsters 3 and 4 are twisted screw-shaped by 90 °. The fastening of the legs with the seat frame is made by spikes formed by the ends of the individual strips of plywood, which are properly positioned for this when they are glued together. As a type of construction, the second additional bars 3–3 and 4–4 may, not income to the floor, connect to 9 CORE bars 1–1, above, being also twisted helically to connect their upper ends with the seat frame. In this case, they will be more like the appearance of the struts. To form the seat 5 (Figs. 1, 3 and 4), the plywood strips are bent around the front seat of the chair (narrowed back), and the back part of the frame is formed by extension of the side plywood strips bent for this purpose under ANGLE 90, gluing part.m new ones. When gluing the seat frame, in it, separate plywood skirts are cut in the corresponding places to form the nests 7 and 8 (Fig. 3) for spikes of legs or other bars. ; The lateral bars of the legs of the chair are fastened additionally in pairs with the tips 9-9; The frame can be connected with the frame of the projectile (with the rims 10-10 (Figs. 1, 2). The fastening of the racks with the tips and the frame of the seat is made on spikes, according to the type of connection of the legs to the seat. -11 (Figs. 1, 2, 3), which at their ends enter between the main and additional leg sticks and are attached thereto by screws or dowels passing through both leg sticks and through the end of the link 11. The back of the chair consists of two main bars 12-12, connected at the top by arcs 14, 15, 16 (Fig. 1, 2). Bars 12-12 rest on the rear legs 2-2 below, for which their ends are cut along the slope line of these legs, with some of the plywood strips forming the bars 12 placed on the side surface of the legs and fastened with screws 21, nails or with glue With the frame of the seat bru) Ski 12 - 12 are fastened with screws 19 of FIG. 4) passing through the laid sidebands of the frame. Bbiuie seat strips 12-12 twist in a curved manner to make spike fastenings of arcs 14, 15, 16 with them. The back can be reinforced with additional racks 17-17, slightly diverging upwards and fastened with a pin 14, and with a frame of the seat - screws. In order to give greater strength to the joints of bars 12–12 with Si, an iron strip 18 (Fig. 4) is inserted into the frame of the latter between the individual strips, which on one side is fastened to the frame of the seat with a screw .19, and on the other, screw 19 For the same purpose, stripes 12–12 are inserted between the Thai and Iron stripes 20–20 (Fig. 4) between the plywood, through which screws 19 and 21 pass through the bottom, and screws 22 at the top, which tightly screw the plywood strips together. 12-12 (fig. 2). The hole for the screw 22 in one of the strips is made elongated, as a result of which the strips get the possibility of mutual displacement and the back of the chair turns out to be springy (due to the elasticity of the veneer and metal strips). The seat itself is made like that of ordinary chairs — solid slightly curved plywood, patterned plywood, or whatever. As a variation, in FIG. Figure 3 shows a seat which is formed by fan-like diverging plywood strips 23 slightly curved and attached to the seat area. For the elevation, forge iron strips are laid below these strips. The device backrest at the top may. Be of another kind. So, bars 12-12 can be bent at the top in the form of an arc, in the form of a bend in Vienna chairs, or otherwise. The insertion of metal strips (forging iron) between the veneer strips described here or the stripping of these strips from the outside can also be applied in all other parts of the chair (in legs, passageways, seat frame, etc. (it. 24 in Fig. 4).

The described production of bars from plywood strips and the method of their interconnection can be applied to the device and other types of furniture, such as tables, stools, benches, beds; chairs and so on. At the same time, to prevent mutual shift of the bands.

joined into the bars, additional layers of table glue, liquid glass or of broken glass, iron filings, sand, etc. of substances i / a connected with glue or without glue can be applied between the plywood. With a strong clamping of the plywood strips, individual solid particles of such substances are pressed into the plywood on both sides and fixed in this position either by clamping the joint or by the adhesive itself. A similar method is applicable when joining plywood blocks together. , FIG. Table 5-10 shows another exemplary plywood stool design. The seat frame is made up of two or more plywood strips 1, 2, 5 arranged by ledges one relative to the other and connected by nails, wooden dowels or otherwise: A lattice 4 (Fig. 5, 9) is applied to the ledge formed inside thin strips mutually intersecting with cuttings into the floor of the tree. The ends of these bands are included in the notches of the frame 5 (Fig. 5). Seat 6, carved out of plywood, is inserted into the ledge of the boron. Strip 1-1 (Fig. 5, b and 9) and rests on the strips 5, the grill 3 and 4 and partly on the upper ends of all four legs; the seat can be fixed with small studs, as is usually done for plywood seats. With a solid stool frame and a solid seat, the Zi4 grille is not necessary. The legs of the stool 7-g-7 (Figs. 5, 6) are cut out of the plywood sheet according to the shape indicated in Figs. ten; Such a blank is trough-shaped along its entire length / length, stronger at the bottom, with the expanded end entering the seat frame between its two strips, where it is fixed. The notches 8 (Fig. 10) make it possible to position the leg somewhat inclined to the vertical axis.

The lower end of the stem (Fig. 7, the cross section rio de e in Fig. 6) is bent in the form of a sleeve, and inside it is fixed on the nail a shaped bell box (inset) 9 (fig. 6; eu, except for TGO, on the ends The metal nozzles 10 (fig. b, 8) can be put on the legs. To eliminate the cracking of the tree with a sharp bend of the leg, a wedge-shaped cut-out 11 can be made at the bottom of the workpiece (fig. 10). 12-12 (figs. B and 7), consisting of two or more plates, which are fastened with the legs on the keys, on the nail with screws It is possible to do this in places of ring-jacks 9; see this kind of connection - in Fig. 22.) At the crossover point, the communications are fastened with dowels 13 (Fig. 7 and 8). Crusades can There may also be a different form, for example, in the form of two wooden bars cutting into the floor of the tree, bamboo, reed bars, etc.

FIG. 11-16 a slightly different arrangement of the legs and the seat frame is shown. FIG. 11 and 12 leg has an additional strap. 1, trapezoidal or straight, 1st form (see sections in Fig. 12), which is fastened at the top with the strip 2 of the seat frame; the frame is then stiffer in the corners. FIG. 13, 14, 15, 16, the main strip forming the leg 1 is not arched by the half-pipe, but taken in a flat form; A small notch 11 can be made at the top of it. To counteract the buckling, each pair of strips forming the leg is indicated by wooden struts 3 (Fig. 14) or by means of wave-shaped inserts 15 (Fig. 16), successively nailed to the and another lane. Corna io FIG. 13 seat round, with additional inserts 3 in the frame. FIG. 14, a dotted line shows another arrangement of the crosses 5; they can also be replaced with rings, like those of Vienna chairs, from one or several strips of one or another cross-section (see, for example, in Fig. 21). FIG. 17 and 18 show the structure of the legs of three flat plywood strips. In cross section in FIG. 17-a, the dotted line shows a curved bar 1, the type of which can be used to connect three parts of the leg in several places. The legs of the stool can also be made using any of the methods shown in FIG. 23-29.

A plywood table is molded, approximately, in the same way as a stool, only with an increase in the length of the legs and the area of the dining room as compared with the seat.

stool. For larger tables, tabletops and a sub-table are shown in FIG. 19 and 20. The basement consists of a wide strip 1, to which a strip 2 is nailed to the bottom, from the inside, is bent at the corners along circumferences of different radii. The junction of the bands Can be / produced at the attachment points of the legs. In order to prevent the hanging edges of the thin table top from bending, a wide strip b is nailed to the bottom of the table top, which can be bent along the entire length so that

. so that its edge, slightly overhang, abuts against lane 1. Grid ends 3 and 4 fit precisely into the notches of lane 1, with an emphasis

B strip 6. In order to reinforce the edge of the table top 5, an esh, e strip 7 can be hammered under it. In FIG. 31 shows a different method, the device of gratings of wavy strips fastened at points 2 by rivets or other clips. The substratum inside can be further strengthened by a lattice with larger cells than in the tabletop.

FIG. 21 shows another exemplary plywood chair structure. Compared with the stool, the cross ties 1 are raised upward and, when crossed, are moved apart. The fastening of their ends can be done with inserts (Fig. 22) or with metal clips. The rear legs 2 and the legs 3 supporting the back may be cut out together from a single sheet, according to the shape shown in FIG. 30. The backrest 4 is nailed or screwed to the posts 3. In FIG. 23-25, 27--39 and 32 show cross-sections of fan-gray bars, which can be used in various types of furniture. FIG. 23 shows a section of a bar, consisting of two strips 1 and 2, connected by triangles and inserts 3. The link can be

 also achieved with the help of two wavy strips 2 (Fig. 6), knitted together between themselves at points 3-3; in fig. 28 shows a cross-section of a bar with such a wavy connection with a very short strip-1 shape. FIG. 24 shows a section of a bar consisting of three layers | e, forming grooves along the edges. FIG. 25 is a cross-section of a bar of two strips with additional strips 1 and 2 along the edges. In FIG. 29 two lanes are swirled along different radii. FIG. 26 and 27 illustrate the structure of an I-beam bar. Pr.i uve; Considering the width of lanes 2-2, in this case, the juice of the required shape is obtained. A tubular bar of this kind can be obtained from two bars in FIG. 26 and 27 by inserting one into the other in such a way that all the undulating inserts of the plates 2-2 merge, being located symmetrically / about the axis. Similarly, a circular section is formed, shown in FIG. 32; The junction of the gorged halves of such a tube may overlap the wavy inserts of one of them. In the nodal joints of the parts of plywood furniture structures, we apply the method of metal fastenings made of tape iron or copper, shaped swashes, brackets, rings, etc.,

As the main material for the described furniture, all types of non-glued and glued fayers manufactured as well as semi-finished products of glued plywood (veneers, shirts) and various kinds of plywood wastes can be used. BnojiHe / it is also appropriate to use combinations of plywood with natural, hollow material like bamboo, cane, and reed. others

Color finishing of furniture made of plywood can be limited to painting only visible exterior parts, and can be applied to all parts and parts before assembling them. In addition to the usual type of painting with oil and other paints, the method of color coating by burning, etching, staining, embossing and patterned patterns from through holes is widely applicable. The usual methods of preserving wood by prilling, impregnating with various compositions are also quite applicable here, ii
