Abstract

The invention relates to means for pivoting and fixing doors and can be used in the furniture industry. The purpose of the invention is to simplify the design. The hinge latch is made in the form of a plate two-armed lever mounted on an additional axis with the possibility of rotation. The lever at the ends has supporting surfaces, one of which serves to rest into the body, and the other, made with a curved arcuate, interacts with the working surface of the shackle, also made arcuate. 2 hp ff. 4 il.

Description

This invention relates to turning and fixing doors and can be used in the furniture industry.

A four-hinge loop is known, comprising a body and a cup connected by the outer and inner earrings, a spring-loaded retainer, one of the steps of one end side forms a stop surface for the outer earring, and in the recess of the second retainer step one of the axes of the inner earring is located. When the hinge cup is rotated under the action of the spring, the retainer performs a reciprocating-and-forward movement, alternately interacting with the inner and outer loops.

The disadvantage of the design is the complex shape of the lock.

A four-hinge loop is also known, comprising a body and a cup connected to each other by two links, having means for fastening respectively to

the fixed part of the furniture and in the casement, a spring-loaded fixer having a concave surface in contact with one of the earrings.

The disadvantage of the loop is design complexity.

The purpose of the invention is to simplify the design.

Figure 1 shows a loop with the open position of the sash; figure 2 is the same, top view; FIG. 3 shows a loop fixed in the closed position; figure 4 - two shoulders lever lock.

The loop consists of a cup 1, fixed on the leaf 2, having axes 3 and 4, by means of which plate earrings 5 and 6 with a rounded working surface 7 are installed in the cup. The other ends of earrings 5 and 6 are mounted with axes 8 and 9 in the case fixed in the fixed part of the furniture. Spring-loaded latch 10 is made in the form of a plate of two shoulders lever mounted on an additional

the axis 11 is rotatable and has supporting surfaces at the ends, one of which 12 serves to rest the body, and the other 13 is arcuate to interact with the working surface 7 of the earring 6.

The latch 10 and the spring element 14 cooperating with it are located in the housing 15, in which axes 8.9 and 11 are fixed. The housing is mounted on a fixed part of the furniture by means of an adjusting screw 16 and a fixing screw 17 through the bar 18. The loop works as follows.

When opening and closing the housing 15 is in a fixed position, and the cup 1 moves along a path defined by a four-hinge mechanism. The spring element 14, being in the pressed state, constantly acts on the latch 10. In the open position of the hinge, the latch 10 under the action of the spring element 14 by the locking surface 12 abuts against the housing 15 and does not interact with the link 6. When the hinge is closed under the action - by force applied by the man to the flap 2, the cup 1, moving along the path defined by the four-hinge mechanism, causes the shackles 5 and 6 to rotate around the axes 3,4 and 8,9, while the working surface 7 of the shackles 6 rotates axis 9, interacts with the supporting surface 13 of the two shoulders lever 10, and turning it on the axis 11, removes from the interaction the supporting surface 12 with the housing 15, compressing the spring element 14. With further rotation of the earring 6, its working surface 7 intersects the point of the maximum protrusion of the arcuate supporting surface 13 of the latch 10.

After that, the force of the spring element 14 transmitted through the latch 10 creates a torque on the shank 6, which rotates the cup 1 to the Loop position.

When opening a hinge under the action of a force applied by a person to the flap 2,

the cup 1 moves, turns the earrings 5 and b, while the working surface 7 of the earring 6 interacts with the supporting surface 13 of the retainer 10. After the arcuate working surface 7 of the earring 6 and the supporting surface 13 come out of contact, the earring 6 does not interfere with the movement of the retainer, 10 which, under the action of the spring element 14, is pivoted up to the stop by the surface 12 into the body 15. The cup 1, moving along a trajectory defined by the hinge mechanism, occupies the Open position.

The advantage of the proposed loop is that the interaction of the working surfaces of the retainer and the earring is carried out on the part of the loop movement area, which reduces their wear and allows to increase the reliability of the loop with a simple design of the retainer.
