Double desk of Labutin

The utility model relates to children's furniture and can be used in schools and kindergartens.

Our industry produces separately set tables and chairs 1 which are convenient in arrangement, but in a hygienic sense they are not functional, because there is no fixed distance (sitting distance) between the table and the chair, which can lead to a violation of the child’s posture and increased fatigue during study. There is school desk 2, in which the table is rigidly fixed with a seat; however, the shoulder girdle of the seated person is in tension due to the lack of proper support of the forearms. There are 3 desks, which with the help of a telescopic stand changes the height of the desks and countertops, the disadvantage of such desks is the design complexity, the shoulder girdle is stressed due to the lack of proper support of the forearms. There is a more functional desk 4, consisting of a countertop, a frame with supporting legs, a seat, a back, armrests and leg supports, but the drawback of the desk is the complexity and fragility of the design.

The utility model is based on a double school desk 5, including a countertop, an armchair with a seat, back, armrests and leg support, a countertop on the side of the hinged covers and hinged covers with armrests form a single plane. The positive in this design is that it is more hygienic, and the disadvantage is the complexity of manufacture and fragility.

The present task is achieved in that the double desk of Labutin includes a frame, a countertop, a seat, a back, armrests, a leg support, while the countertop, hinged covers and armrests form a single plane, and the metal frame is made of two C-shaped bases that are connected between transverse and longitudinal screeds, transverse screeds are installed under the tabletop, back, seat, footrest, the middle armrest is mounted on the longitudinal screed, while the longitudinal screed is installed in the middle between pepper screeds installed under the tabletop and back, while a longitudinal screed and cross screeds under the back, tabletop, armrests connected to the C-shaped bases form a single plane, the frame consisting of; the C-shaped bases and screeds can be made of quadrangular profile, also C-shaped bases can be made of metal pipes, and the longitudinal screed from a quadrangular profile, also C-shaped bases can be made of a quadrangular profile, and screeds from metal x strips or corners, a metal quadrangle is installed inside the C-shaped bases under the tabletop, and in the rest of the joints metal triangles, the seat and back can be made of several wooden bars with gaps between the wooden bars, C-shaped bases can be made of solid cast .

The proposed utility model is illustrated by the drawings, in which FIG. Is a front view of the desk, FIG. 2 is the rear view of the desk, FIG. 3 is the top view of the desk, FIG. 4 is the side view of the desk while the right lid is raised and one student is standing up, FIG. 5 is an external view. metal frame.

A double desk of Labutin contains a frame, a countertop 2, a seat 6, a backrest 7, armrests 4 and 5, a footrest 8, while the countertop 2, hinged covers 3 and armrests 4 and 5 form a single

the plane, and the metal frame is made of two C-shaped bases 1 which are connected by transverse 9 and longitudinal 10 screeds, transverse ties 9 are installed under the tabletop 2, back 7, seat 6, footrest 8, the middle armrest 5 is mounted on a longitudinal screed 10, while a longitudinal screed 10 is installed in the middle between the transverse screeds 9 installed under the tabletop 2 and the backrest 7, while the longitudinal screed 10 and the transverse screeds 9 under the backrest 7, the countertop 2, armrests 4 and 5 connected to the C-shaped holes 1 form a single plane, and also the frame consisting of C-shaped bases 1 and screeds 9 and 10 can be made of a quadrangular profile, as well as C-shaped bases 1 made of metal pipes, and the longitudinal screed 10 of a quadrangular profile, and The shaped bases 1 are made of a quadrangular profile, and the ties 9 and 10 are made of metal strips or corners, and also inside the C-shaped bases 1, a metal quadrangle 11 is installed under the tabletop 2, and metal triangles 12 at the other joints, and the seat 6 and backrest 7 are made of several wooden bars with gaps between the wooden bars 13, and the C-shaped base made from whole -1 casting.

The double school desk is used as follows: when the student is working sitting (Fig. 4), his elbows are supported on the armrests 4 and 5, and his legs can be placed on the leg support 8. When rising and exiting from the school desk (Fig. 4), the hinged lid rises 3 and the student gets up or leaves the desk. The frame (Fig. 5) of the school desk is made of metal, where all the joints are welded, which can be done on the street or in school workshops. Worktop 2, hinged covers 3, armrests 4 and 5, backrest 5, seat 6, footrest 8, book stand 14 are mounted on the frame using bolts or rivets. For

stability of the middle 5 and side armrests 4 (Fig. 3,4) mounted on a longitudinal screed 10 and C-shaped bases 1, they are pressed from the back with a back 7. To comply with the tilt angles and sizes, prepare quadrangles 11, corners 12, as well as other structural elements of the frame it is possible according to templates, according to GOST. The transverse screed 9 under the leg support 8 (Fig. 1.5) does not protrude beyond the leg support 8. The two-part bench of Labutin can be produced with corners 11 and quadrangles 12 and without them (Fig. 4,5). Seat 6 and backrest 7 (Fig. 2,3) can be made of a solid board like Erisman's desk, and can be made of wooden bars at intervals of 13 to prevent stagnation in the back muscles, as well as in the gluteal and femoral muscles. Tolsh; the ina of the bars on the back 7 and seat 6 depends on the bending of the back and seat according to the age-related anatomical features of the pupils; theirs. The exact dimensions and angles of the metal triangles 12 and quadrangles 11 inside the Shaped bases 1 allow in ordinary workshops to make a welded construction of C-shaped bases 1 according to GOSTs. Simplification of the design, which is not related to modern wood processing technologies - using glues, allows us to produce GOST, tabletop 2, hinged covers 3, armrests 4 and 5, backrest 7, seat 6 in any regional center where there is a carpentry workshop. Also, to reduce the cost of construction, large volumes, it is possible to manufacture C-shaped bases 1 by metal casting. Also, the cross ties 9 (Figs. 1,2,5) under the seat 6 and the leg support 8 can be made of a square, pipe or thick wire. For the stand for kg books 14 (Fig. 1.4), you can use a steel corner welded to the base.
