Abstract

Self-adapting lath bottom for example for beds and chairs, said lath bottom having at least two frame beams (1), to which are attached with bearings rope sheaves (3) over which run ropes (4) supporting, with the help of other rope sheaves (5) and support members (14), laths (2) connected with one another. It is the intention of the invention to bring about a steady and reliable lath bottom and its rope apparatus. In a lath bottom structure in accordance with the invention, the frame beam (1) consists of a minimum of two adjoining, parallel plates (13), of which the gap is fitted with support rope sheaves (3) and other ropes sheaves (5) made to move with the bottom ends of the support members (14) between the frame plates only in a vertical direction or in a corresponding direction if the frame beam (1) is in a position other than horizontal.

The invention relates to furniture, in particular, to self-forming rack and pinion bases for beds and seats,

The purpose of the invention is to improve performance by increasing stability and reliability. FIG. 3 shows a rack and pinion.

base, general view, top and side view; Figures 4 and 5 show the same longitudinal and transverse cuttings. On fig. 7 and 8.9, the rail and the supporting element, as seen from the side and the front, respectively; FIG. 10 shows a node connecting a support member with a rail; on figl - npo longitudinal incision in the area of liners.

The self-forming lath base contains at least two longitudinal joints connected to each other by means of frame elements; 1e support beams 1 and 2, ropes 3 located along the beams and 2 and connected to them by means of pulleys A, the mounting base is formed by the interaction of the rope system

on the beams I and 2 with the help of bearings 5. Perpendicular to the beams of 25 pulleys of the tape 15. The rails 6 1 and 2 are arranged by the rails 6, which are made with a flexible tape 15 so that the ropes 15 are flexible through the supporting elements 7 and additional pulleys 8.

The rack base is provided with inserts 9. Each of the supporting beams 1 and

K sagged between 6, then the formation of the rails occurs as follows. At the time of lowering

2 includes two boards 10 parallel to each other. Each of the supporting elements 7 includes two sections 1 1 placed between the board: 10 beams, and each of the inserts 9 is embedded on the boards 10 of the supporting caps 1 and 2 and placed between every two

pairs of pgs 11 support elements 7, I

Each of the additional pulleys 8 of the rails 6 is mounted on the plates 15 of the epor element 7 and placed between them, and each of the rope pulleys 4 is mounted on the liner 9 and has guide surfaces 12 for sliding engagement with the end surfaces 13 on its end portions feed 11 supporting elements 7 when they are moved in the vertical direction.

The rack base has restrictive elements 14, made in the form of a steel cable or rod, passing over the cable pulleys 4 and secured on the support beams 1

The slats 6 cBOHt Oi are interconnected by means of a flexible elastic band 15, the length of which between two adjacent strips 6 is chosen taking into account the limitation of the distance between the edges of these strips.

The interfacing end face sliding surfaces 12 of the contributed 9 and the surface 13 of the feed 11 of the supporting elements 7 are V-shaped. Each of the rails 6 is connected to the support element 7 by means of a slide 16, which is parallel to the rail, and a bracket 17, one of these elements being placed on the rail 6, and the other on the support element te 7, If the slide 16 is placed on the opona then it can be connected to it by means of a hinge 18.

The rack base is formed by the interaction of the cable system.

pulleys of the tape 15. The connection of the rails 6 with a flexible tape 15 is made so that the connecting tape 15 is flexible, slightly

k sagging between 6, then the formation of the rails is as follows. At the time of lowering

rails 6 down when loaded; a connecting tape of 15 tons is flexible; no adjacent rails 6 are down; at the same time, they are inclined. This prevents the rope from raising the adjacent rail 6 higher than the flexible connecting tape 15 allows, while simultaneously transferring its lifting effect to the next rail 6. When the adjacent rail 6 tilts under the influence of the flexible connecting tape 15, it raises the next rail up, not being under load using flexible connecting tape 15, transferring the lifting effect of the rope

3 on subsequent rails, so the rack base forms smoothly. The connecting tape 15 is only slightly narrower than the support knobs 1 and 2, therefore it protects the parts inside the support beam from being contaminated.

neither, but does not prevent full ventilation of the rack base.

Support beams 1 and 2 can be made of two or three support boards 10. The larger the number of rails, the narrower they are, which means that the base will form better. The structure of the three boards can be moved in such a way that the supporting elements in one row support each second rail, and the rest of the slats rest on a row of support elements 7 installed between adjacent support boards 10. Working space of the support cable pulleys 4 Between the supporting boards 10 is equal to 6 width, so that in the construction of three supporting boards the number of rails can be doubled without reducing the working space of the supporting cable pulleys.

FIGS. 4 and 5 show the structure of the rack and support pulleys, their placement in the support beam 1 and the attachment of the flexible tape 15 to the rail 6,

Support element 7 consists of two support plates 11, between which in the lower part there is a canet pulley 4 with a bearing, in the upper part there is a swing 1- with a hinge 19 with a bearing. Rope pulley 4 and kachaidium hinge 19 are attached with bearing sleeves 20 and bolts 21 to support plates P so that the length of bearing sleeve 20 determines the distance between support plates 11 when they are pressed against the ends of bearing sleeve 20, the attachment of rail 6 is described below. to swing hinge.

The outer edges of the base plates 11 have-. The shape of the V-shaped ridge, through which they are inserted into the corresponding V-shaped grooves of the insert 9, One of the guiding surfaces 12, 13 of the insert 9 or base plates 11 is covered with a rigid sheet, and the other is made of gshastmas 10

prevent cable pulleys A from escaping, pierce the steel conductor 14 through all the supporting elements 7, securing it on the liners 9. After that, a second supporting durability Ure is applied to the assembled structure, after which the supporting boards are fixed with rods 22. The assembly can also be carried out in another way.

The rail is attached to the swinging {yc hinge 19 with the help of the slide 16. Under the rail b, the rear sight 23 is attached, which simultaneously fixes the flexible lei 15 that 15 between the rail 6 and the entire 23. The swing hinge 19 connects to the whole 23, so that its round the upper end is inserted into the groove in the slab, and then a hinge is formed. This hinge is necessary, as the rail 6 bends under load and the hinge contributes to this deflection.

The ease of transporting the bed or seat and the ease of assembling them at the place of use depends largely on the presence and use of the slider 16. The ribs 6, connected on the belt 15, form a slatted carpet that can be rolled up and easily packaged.

The remaining parts - supporting beams 1 and 2 and other frame elements - are pre-assembled so that they include a block of cable pulleys and supporting elements 7. Assembly takes place so that the sliders 16 supporting elements 7 of both supporting beams 1 and 2 lay each B 23 round slats

The back plate in the rear pillars prevents the rails from moving from their place on the support beams 1 and 2. The design of the ram can be done in other ways, the most important thing is its filling.

a slidable sliding fit between the base plates 11 and the sleeve 9, From the point of view of fixing the rigid sheet, a method in which the rigid sheet is covered is not only covered by the V-shaped grooves, but also by the side surfaces of the insert 9, the Hard sheet is attached to frame with the same rods 22 as the insert itself 9.

The liner 9 is an integral part, and the supporting cable pulley 4 is attached directly to it by means of a bearing. The assembly of the supporting beams 1 and 2 can be carried out quickly by inserting pre-assembled inserts 9 with rods 22 and supporting elements 7 further on the supporting plate 10 and passing the rope 3 through the pulleys along the entire length of the support bars 1 and 2.
