Abstract

FIELD: furniture fittings. The purpose of the invention is to increase the reliability of locking the hinge in the closed and open positions of the leaf. The hinge blocks are connected in four-bar. A spring is pivotally mounted on the axis of the outer cable in the fixed block, interacting with one branch with the axis of the inner rod fixed in it, and the other with the outer rod. 1 hp f-ly, 7 ill.

Description

The invention relates to furniture fittings for hanging flaps.

The purpose of the invention is to increase the reliability of fixing the hinge when the sash is closed and open.

Figures 1, 2 and 3, 4 schematically show a loop with open and closed positions, respectively, longitudinal cuts, two embodiments; figure 5 - external ha, general view; 6 is a spring (embodiment of FIGS. 1 and 2); Fig. 7 shows the external ha with the spring (the embodiment of Figs. 3 and 4).

The furniture hinge consists of two blocks 1 and 2. Block 1 is fixed and has means for fastening to the furniture body, and block 2 is movable and has means for fixing on the sash. The loop has two traces of gi — outer 3 and inner 4 for hinge communication between each other of blocks 1 and 2.

Each of t g 3 and 4 is installed in the housings of 5 and 6 blocks 1 and 2 with the help of axes 7-10 with the formation of a hinged four-link.

The loop has a means of fixation in the closed and open positions, made in the form of a spring 11, hinged on the axis 8 of the outer cable gi 3.

The spring 11 has two branches 12 and 13, bent in opposite directions, with one branch 12 interacting with the outer surface of the outer tee 3 and has an arcuate protrusion 14 in its middle part, which interacts with the inner surface of the body 5 of the movable unit 2, and the second support The branch 13 passes through the notch 15 of the body 6 of the stationary block 1 and interacts with the axis 10 of the inner tube 4 fixed therein.

The branch 12 of the spring 11 can be made in one piece with the outer pull 3, the latter being made of an elastic material, and the arcuate protrusion 14 is formed by the surface of the outer pull rod 3. In Figures 6 and 7, the solid line shows the spring in the initial position after manufacturing, by a dashed line - its state in the loop with the shutter closed, with a dash-dotted line - with the open shutter.

The device works as follows.

In the open state of the spring loop 11, being in the unfolded state,

Mits take the starting position. In this case, with its support branch 13 Stremits spring, turn the body 6 of the fixed block around the axis 8 in a clockwise direction. This rotation is prevented by the edge of the casing p of the movable block, which rests on the lamellar internal rod 4, the spring 11 with its second branches, acting on the axis {3 of the casing 5 of the movable block 2, tends to turn it around the axis 8 of the inner plate stint counterclock-wise. & this rotation is prevented by the edge of the body 5 of the movable block 2, which rests against k plate plate 4.

In the closed state, the spring 11, which is in the unfolded state and therefore, tries to assume its original position, with its support branch 13, abutting against the body 6 of the stationary unit 1, tends to turn the latter around BSI 8 clockwise. the body 5 of the movable unit 2, which compresses the arcuate protrusion 14, prevents rotation. The second ends of the spring, abutted against the axis 7 in the case of the mobile unit 1, tend to rotate the latter counterclockwise. This rotation is prevented by the housing 5 of the movable unit 1, which abuts against the spring 11.

To close or open the hinge, it is necessary to overcome the force of the movable body, which compresses the spring 11.

Claims (2)

Claim 1 Furniture four-hinge loop comprising two blocks, one of which, ft I fixed, has means for fixing on the furniture case, and the other is movable, has means for fixing on the shutter, two ropes are external and internal for hinging communication between each other blocks, installed in the cases of both blocks by means of axes with the formation of a four-shafts, and means fixing the movable unit with closed and open the positions of the loop, made in the form of a spring, pivotally mounted on the axis of the outer linkage fixed in the fixed block and interacting with the axis of the inner linkage fixed in it, characterized in that, in order to increase the reliability of fixation, the body of the fixed block has a notch, the spring branches of the fixation means are bent in opposite directions, at the same time, one branch interacts with the outer surface of the outer cable and has in the middle part an arcuate protrusion interacting with the inner surface of the body of the movable block with the closed position of the sash, and the other branch of the spring passes through the notch of the body of the fixed block to interact with the axis of the internal rod fixed in it. 2. The loop according to claim 1, that is, the fact that the outer hectare is made in one piece with the spring of the fixation means of elastic material, and interacting with the body of the movable unit The arcuate protrusion is formed by the surface of the outer tie bar.
