Abstract

FIELD: production of furniture. SUBSTANCE: furniture is composed from hollow blocks made in the form of similar rectangular parallelepipeds with sides a, b,c and a¹, b¹ c¹, respectively. b = a + kx, c = b + kx, b¹ = a¹ + ky, c¹ = b¹ + ky, where a, a¹ are values selected for groups of children of different age; k>0 is arbitrary number; x/y ratio is 1.5. Parallelepiped faces have openings of diameters D(ab) <D(ac) <D(bc), d (a¹b¹) <d(a¹c¹) <d(b¹c¹), respectively. According to first version, furniture blocks have three faces and three rigid binding members. According to second version furniture is provided with panel mounted in vertical position on two equally sized blocks with sides a,b,c or a¹, b¹, c¹. Height of furniture is changed by overturning parallelepipeds from one face to another. EFFECT: wider operational capabilities, simplified construction and enhanced reliability in operation. 4 cl, 3 dwg

Description

 The invention relates to furniture, in particular to sets of children's furniture.

 Known children's furniture containing at least one hollow three-dimensional block made in the form of a rectangular parallelepiped with an opening on the sides - US patent for industrial design N D 299600, class. 6-03, 1989. The disadvantage of such furniture is the impossibility of using it for various age groups of children.

 Combined children's furniture is also known, consisting of at least two hollow three-dimensional blocks - RF patent for industrial design N 36337, class. 6-05, 1993.

 This known furniture is the closest analogue to the claimed invention in all variants of its implementation.

 The disadvantage of this furniture is its difficulty in manufacturing for various age groups of children with constantly changing child growth.

 The invention allows to ensure the simplicity of the design of furniture, its use for various age groups of children, and also to expand its functionality.

определяются по формулам

По второму варианту выполнения указанный технический результат достигается за счет того, что в мебели детской комбинированной, состоящей по крайней мере из двух полых объемных блоков, последние выполнены в виде подобных прямоугольных параллелепипедов с ребрами a, b, c и a₁, b₁, c₁ соответственно, каждый из блоков включает три смежные грани и три жесткие связи, при этом размер ребер определяется по формулам
b = a + kx; c = b + kx; b₁ = a₁ + ky; c₁ = b₁ + ky,
где a, a₁ выбираются для различных возрастных групп детей;
k - произвольное число больше нуля;
отношение x/y = 1,5.The specified technical result is achieved due to the fact that in combined furniture for children, consisting of at least two hollow three-dimensional blocks according to the first embodiment, the latter are made in the form of similar rectangular parallelepipeds with edges a, b, c and a ₁ , b ₁ , c _1, respectively, the size of which is determined by the formulas:
b = a + kx; c = b + kx; b ₁ = a ₁ + ky; c ₁ = b ₁ + ky,
where a, a ₁ are selected for different age groups of children;
k> 0, an arbitrary number;
x / y ratio = 1.5,
the diameters of the holes made in three adjacent faces of the blocks, D _ab <D _ac <D _bc and

determined by the formulas

According to the second embodiment, the indicated technical result is achieved due to the fact that in combined children's furniture, consisting of at least two hollow three-dimensional blocks, the latter are made in the form of similar rectangular parallelepipeds with edges a, b, c and a ₁ , b ₁ , c _1, respectively, each of the blocks includes three adjacent faces and three rigid bonds, while the size of the edges is determined by the formulas
b = a + kx; c = b + kx; b ₁ = a ₁ + ky; c ₁ = b ₁ + ky,
where a, a ₁ are selected for different age groups of children;
k is an arbitrary number greater than zero;
x / y ratio = 1.5.

According to the third embodiment, the indicated technical result is achieved due to the fact that the combined children's furniture containing hollow three-dimensional blocks is equipped with a panel horizontally mounted on two blocks of the same size, the blocks are made in the form of similar rectangular parallelepipeds with edges a, b, c or a ₁ , b ₁ , c ₁ , while the size of the ribs is determined by the formulas:
b = a + kx; c = b + kx; b ₁ = a ₁ + ky; c ₁ = b ₁ + ky,
where a, a ₁ are selected for different age groups of children;
k> 0 is an arbitrary number;
x / y ratio = 1.5.

In FIG. 1 presents the 1st version of children's furniture,
in FIG. 2 - option 2,
in FIG. 3 - option 3.

The dimensions of the ribs a and a ₁ are selected depending on the purpose of the furniture. So, for example, if the furniture should be a set in the form of a table and chair, ribs a (table) and a ₁ (chair) should be selected on the basis of standard sizes for children's and school furniture (GOST 11015-93 and 11016-93), see .table.

 The ratio x / y = 1.5, since the change in table height from frame size to frame size is 60 mm, and the chair - 40 mm.

Changing the height of the furniture is carried out by simply turning the box from one side to another. So, for example, if we take a = 460 mm, and a ₁ = 260 mm (1st size), then b = 520 mm, c = 580 mm, b ₁ = 300 mm, c ₁ = 340 mm (at x = 60 mm, y = 40 mm, k = 1). Then we get three sizes in one set (1, 2, 3). Choosing k = 2, we get a table and chair 1, 3, 5 sizes. The size of the ribs is determined by the formulas
b = a + kx; c = b + kx; b ₁ = a ₁ + ky; c ₁ = b ₁ + ky,
where a, a ₁ are selected for different age groups of children;
k> 0 is an arbitrary number.

Диаметры отверстий D_ab, D_bc, D_ac выполняются такими, чтобы меньший параллелепипед мог вставляться в больший, причем в наименьшее отверстие D_ab второй параллелепипед входит только гранью с отверстием

в отверстие D_ac - гранями

а в отверстие D_bc - любой гранью. Это может быть использовано для тренировки сообразительности и развития конструкторского мышления у ребенка, при этом

Полые блоки могут дополнительно использоваться в качестве емкостей для хранения, например, игрушек, в этом случае отверстиям могут быть заглушены.In the furniture of FIG. 1 (1st option) holes made in three adjacent faces provide comfortable seating, as they may have the legs of a sitting child, while

The diameters of the holes D _ab , D _bc , D _ac are such that the smaller parallelepiped can be inserted into the larger one, and the second parallelepiped enters the smallest hole D _ab only with a face with a hole

in the hole D _ac - faces

and in the hole D _bc - any face. This can be used to train ingenuity and the development of design thinking in a child, while

Hollow blocks can be additionally used as containers for storing, for example, toys, in which case the holes can be plugged.

 Blocks stacked on top of each other or stacked side by side can be game sets. So, for example, vertically placed blocks can be used as a puppet theater, horizontally - as a maze, etc.

In furniture (Fig. 2, option 2), parallelepipeds contain only three adjacent faces, and the missing faces are replaced by three rigid bonds (edges). This design also allows you to adjust the height with a change in the height of the child, the absence of three faces creates comfort for sitting and facilitates the design. In this case, the blocks are easily inserted into each other. The size of the ribs is determined by the formulas
b = a + kx; c = b + kx; b ₁ = a ₁ + ky; c ₁ = b ₁ + ky,
where a, a ₁ are selected for different age groups of children;
k> 0 is an arbitrary number;
x / y ratio = 1.5,
In FIG. 3 presents the 3rd version of furniture. Two hollow blocks having ribs a, b, c and equipped with an additional panel (table top) can form a double-bed table (with adjustable height), and two blocks with dimensions a ₁ , b ₁ , c ₁ and with the panel - a seat.

The size of the ribs is determined by the formulas
b = a + kx; c = b + kx; b ₁ = a ₁ + ky; c ₁ = b ₁ + ky,
where a, a ₁ are selected for different age groups of children;
k> 0 is an arbitrary number;
x / y ratio = 1.5.
