Description

The utility model relates to furniture, in particular to children's furniture, which can be converted from one type to another, and can be used mainly in everyday life.

A children's chair is known (patent US7021705B1, publ. 04/04/2006), which includes two sidewalls connected by a coupler and having a back and a seat.

The disadvantage of this analogue is the limited use - the possibility of its use only as a chair.

A height-adjustable chair is known (RF patent No. 2664662 IPC: A47C 3/20, publ. which is made with a greater length and with parallel horizontal grooves on the side facing the other sidewall, as well as a back connected to the sidewalls and a rearranged seat and footrest, made in the form of plates with the possibility of installation in the grooves of the sidewalls, the horizontal and inclined strips of each sidewall are connected stiffening rib.

The disadvantage of this technical solution is the impossibility of assembly, bulkiness and limited use, due to use only as a chair.

A children's chair is known (the official website of the Konek-Gorbunek company https://www.kon-gor.com/), containing connected left and right sidewalls, each of which is formed by connected horizontal and inclined slats, the latter of which is made with a greater length and with parallel horizontal grooves on the side facing the other sidewall, as well as a backrest, a reversible table, a seat and a footrest made in the form of figured plates, and the seat and footrest are made with the possibility of installation in the grooves of the sidewalls, the horizontal slats are connected by a coupler at the free ends.

The disadvantage of analogue is the bulkiness due to the integral design of the horizontal and inclined bars, the difficulty in assembling for storage associated with the impossibility of assembling the chair without special tools.

An adjustable chair is known (RF patent No. 2664662 IPC: А47С 3/20, A47D 1/04, publ. 08/21/2018), containing the left and right sidewalls connected by the back, seat, footrest and screed, in which there is a long segment with two rows holes on the side surface is inclined at an acute angle to the horizontal short segment, horizontal strips are attached to the horizontal short segments of the left and right sidewalls in the front part, directed forward in working condition, behind the front dimension of the chair, and a coupler is attached in the back part, connecting the sidewalls, to inclined long segments of the sidewalls are attached in the upper part of the back, below the seat and footrest, consisting of plates and attached to the plates from the bottom on the right and left sides of the figured side panels with through holes on the side surfaces, which are aligned with the holes in the sidewalls and are fixed with fasteners .

The disadvantage of the known technical solution is the bulkiness, the possibility of using only as a chair.

The closest to the claimed technical solution is the "Children's Chair" (RF patent No. 102469 IPC: A47D 1/00, publ. 03/10/2011), containing the left and right sidewalls connected by ties, each of which is formed by horizontal and inclined slats installed at an acute angle , the last of which is made with a greater length and with parallel horizontal grooves on the side facing the other sidewall, as well as the back, rearranged table, seat and footrest, made in the form of figured plates with the possibility of installation in the grooves of the sidewalls, the sidewalls are made with through holes for ties, and two ties are connected to the inclined slats of the sidewalls above and below the footrest, and the third - to the horizontal slats at the free ends of the latter.

The disadvantage of the prototype is low ergonomics due to the limited use - only as a baby chair for feeding.

The objective of the proposed technical solution is to improve the ergonomics of the children's chair by increasing the area of its use, which allows you to purchase one type of furniture instead of several.

This problem is solved by the fact that the chair-transformer, containing the left and right sidewalls connected by ties, each of which is formed by horizontal and inclined strips, the latter of which is made with a greater length and with parallel horizontal grooves on the side facing the other sidewall, as well as the back , adjustable seat and footrest, made in the form of figured plates, and the seat and footrest are made with the possibility of installation in the grooves of the sidewalls, which are made with through holes for the ties, and two ties are connected to the inclined slats of the sidewalls above and below the footrest , and the third - with horizontal bars at the free ends of the latter, in contrast to the prototype, the horizontal bars are connected to an inclined fastener with the possibility of rotational movement; in the horizontal slats at their free ends there are blind cutouts for the screed according to its shape, which is made with two through holes on the wide side, symmetrical to the holes on the seat for connection by placing the fixing elements in the aligned holes for fixing in the “Student” position, and for fastening steering wheel in the "Machine" position on the narrow side in the center of the screed, a non-through hole is made. The coupler, made below the footrest, is a U-shaped stop, fixed at one end in non-through cutouts on inclined slats, a round cutout is made in the horizontal slats for its installation. On the inclined planks at the free edge, a through hole is made for rigid fastening of the backrest, which has two holes symmetrical to them, by placing the fixing elements in the aligned holes. On the inclined slats on the free edge there is a vertical groove for fixing the backrest, made with through cutouts along the edges for fixing the U-shaped limiter, at the corners of which two through holes are made, symmetrical to the holes on the footrest for connecting them by placing the fixing elements in the aligned holes for fastening in the "High chair" position. From the bottom of the U-shaped limiter, triangular stops are rigidly fixed, having round holes on one side, symmetrical to the holes on the footrest for connection by placing fixing elements in the combined holes for fixing the footrest in the “Desk” and “Typewriter” positions. All horizontal slots are inclined at an angle of 1-3°. For the position "Machine" in the upper and lower parts of the inclined bars on the outer sides, wheels are symmetrically fixed in pairs with the possibility of rotation.

The transforming chair has 6 versions: folded position, chair, chair with limiter, high chair, desk, typewriter.

The execution of the seat, footrest and limiter of the same thickness allows them to be inserted into the same slots, replacing each other depending on the type of operation.

The ability of one and the same element to be rearranged and perform the functions of another - allows you to create an ergonomic chair that takes up a minimum of space, combining several options.

A transforming chair containing the left and right sidewalls connected by ties, each of which is formed by horizontal 1 and inclined slats 2 (Fig. 1, Fig. 2), the latter of which is made with a greater length and with parallel horizontal grooves 3 on the side facing the other sidewall. The horizontal strips 1 are connected to the inclined fastener 2 4, for example, a bolt, with the possibility of rotational movement of one strip relative to the other.

The elements made with the possibility of insertion into the grooves are the seat 5 and the footrest 6, made in the form of figured plates. Seat 5 is a figured rectangular plate with rounded edges and has two through holes 7 and 8 at the larger side. Footrest 6 is a figured rectangular plate with rounded edges and has two through holes 9 and 10 at the larger side (Fig. 4, Fig. 5).

Sidewalls are made with through holes for screeds 11, 12, 13, and two ties are connected to inclined slats 2 of sidewalls above (11) and below (12) footrest 6, and the third (13) - with horizontal slats 2 at the free ends of the latter (Fig. 7, Fig. 8).

On inclined slats 2 at the free edge, two through holes 16 are made for rigid fastening of the backrest 17, which has two through holes 20 symmetrical to them for fastening by placing fixing elements, for example, bolts, in aligned holes (Fig. 6-9). For better fixation, the back 17 is inserted into the vertical grooves 19 on the inclined slats 2. The back 17 is a figured rectangular plate with rounded edges on one side and has through cuts 20 along the edges. Moreover, when the back 17 is installed in the vertical grooves, the through cuts 20 coincide with the upper grooves 3 of the inclined bars 2 for fixing the U-shaped limiter 21 (Fig. 12). At the corners of the U-shaped limiter 21, two through holes 22 and 23 are made, symmetrical to the holes on the footrest 9 and 10 for connecting them by placing the fixing elements in the aligned holes, for example, with a bolt, for fixing in the “Stool for feeding” position (Fig. 10, Fig. 13, Fig. 14). From below, to the U-shaped limiter 21, triangular stops 24 are rigidly fixed, having round holes 25 on one side, which, when the footrest 6 is placed on them, will be symmetrical to the holes 9 and 10 on the footrest 6 to connect them by placing the fixing elements in the combined holes for fixing the footrest 6 in the position "Desk" and "Machine" (Fig. 11). The fastening of the triangular stops 24 to the U-shaped limiter 21 can be made with two bolts through the holes 26. The U-shaped limiter 21 is made with the possibility of installation in the grooves 3.

In the horizontal slats 1 at their free ends, non-through cutouts 27 are made for the screed 13 according to its shape, and in such a way that when the transforming chair is placed in the “Desk” or “Typewriter” position, the wide edge of the screed 13 is parallel to the floor. The coupler 13 is made with two through holes 28 and 29 on the wide side, symmetrical to the holes 7 and 8 on the seat 5 for connection by placing locking elements in the aligned holes, for example, bolts, to fix the seat 5 in the “Desk” position, serving as a desk table ( Fig. 15-17). On the narrow side, in the center of the coupler 13, a non-through hole 30 is made for fixing the steering wheel in the "Machine" position. The steering wheel 31 has a hole 32 for fastening, for example, with a bolt, into the hole 30 (Fig. 18, Fig. 19).

For the position "Machine" in the upper and lower parts of the inclined bars 2 from the outer sides, wheels are symmetrically fixed in pairs with the possibility of rotation.
