Abstract

The invention relates to devices for joining furniture parts. This is a core-shaped part. It is presented in two options: the screed is single-sided and the screed is double-sided. One-sided coupler has a threaded part and a smooth part with a flat (figure 5). The double-sided screed has a smooth middle part and smooth parts with a flat at both ends (Fig.6). In areas with a flat, there is a conical hole with a vertex in the direction of the flat. The threaded part or the middle smooth part is fixed in the hole of part A. The fixed end of part B or parts B and C adjoins the flat, and is screwed together through the hole. The coupler allows you to reduce the time of manufacture and connection of furniture parts, is more compact in comparison with analogues. To install it does not require additional space, which is important in cases where this space is limited.

Description

To accomplish the same task, there are such devices as a screw, a screw with a nut, a corner screed (MDM catalog - set Moscow, 48, Mikhalkovskaya St., tel. 788-80-08, 788-44-71, fax 788 -44-72. E-MAIL: Furnitura@mdm-complect.ru.URL: http // www.mdm-complect.ru), eccentric screed (MDM catalog - kit, USSR Author's Certificate No. 161880, Cl. F16b 12 / 18, USSR author's certificate No. 1977893, class F16b 12/18), conical screed (MDM catalog kit, RF patent RU 2193121 C2).

A screw or screw with a nut does not provide a connection in the same plane of two furniture parts through a third, they require a through hole in the front part, which reduces the aesthetic level of the furniture.

An angled screed is inferior to perfect devices, in particular, an eccentric, in manufacturability and aesthetics, therefore, it has lost its widespread use at the present time.

For eccentric and conical screeds, as well as for the claimed, make a hole in the part And (Fig.1-6). The hole in the front part A (Figs. 1, 3, 5) is blind.

In contrast to the claimed:

for eccentric and conical couplers, holes are made in the end and plane of parts B and C (the first for the rod, the second for the eccentric or cup), which increases the time and reduces the strength of this section of the part;

for double-sided couplers, 2 eccentrics or 2 glasses with screws are required;

To install the stem, additional space is required between part A and parts B and C.

The conical screed is closest as a prototype of the inventive screed.

The inventive screed is a part in the form of a rod with a base diameter of 8 mm. The coupler is represented by two options: one-sided (figure 5) and two-sided (figure 6). The one-sided coupler has a threaded part from one end and a smooth part with a flat from the other. The double-sided screed has a smooth middle part and smooth parts with a flat on both ends.

The axis of symmetry of the rod is in the plane of the flat, which is limited to a rectangular step. The end of the site with a flat rounded. In this section there is a conical hole with the apex in the direction of the flat, with the center removed from the edge by the radius of the rod.

The screed is made of steel by machining on standard equipment.

The purpose of the use of this screed is to accelerate the assembly process of furniture, increase its manufacturability, and expand design capabilities.

This is achieved by:

The screed consists of one part, which makes it compact.

it does not require holes in the parts of B. and C, which reduces the time of operations prior to assembly and increases the strength of the parts;

it does not require additional space, which is important, for example, when assembling built-in furniture.

The drawing shows the connection of furniture parts using the following devices:

coupler eccentric (figure 1, 2);

conical screed (Figs. 3, 4);

screed of the claimed (figure 5, 6).

For a one-sided screed, a blind hole is made in part A with a diameter smaller than the base, to the depth of the thread. For a double-sided screed, a through hole is made in the part A with a diameter that provides a slight interference fit. A single-sided screed is screwed into the blind hole. A double-sided screed is pressed into the through hole. On the flats, the fixed end of part B or parts B and C is installed with the end to part A. Through the hole in the screed, part B is made or screw B and C are self-tapping screw (self-tapping screw), shifting the point of entry of the screw towards the edge of the screed. During screwing, the self-tapping screw, passing the cone of the head along the cone of the hole, is shifted to the center of the hole.

As a result of this, the furniture parts are pulled together.

Furniture screed in the form of a rod, having for fixing in the furniture part a thread at one end or a smooth surface in the middle part, characterized in that there is a flat on the other end or at its ends, to which another furniture part adjoins at right angles to the first, and a conical hole with an apex in the direction of the flat through which a screw enters into this part.
