Description

FIELD OF THE INVENTION This invention relates to means for hanging a door leaf of a furniture and for securing the door in a closed position.

Known hinge hinge for door leaf, including fixed and pivoting elements, pivotally interconnected by plate levers fixed on axes and forming a four-link link with fixed and pivoting elements, a latch mounted on a fixed element with a spring-loaded locking element interacting with a cam fixed to one of the leaf levers of the four-link.

This embodiment of the locking element does not provide a reliable fixation of the furniture door.

A locking hinge for a furniture door is known, comprising a fixed U-shaped and glass-turning elements, pivotally interconnected by means of plate levers fixed on axes and forming a four-link with movable and fixed elements. On movable articulated

part of the mounted lock with a spring-loaded locking element for fixing the door in the closed position, and the lock is made in the form of a housing with a guide in which the locking element is made, made in the form of a shank with a hook-shaped end located in the cavity of the glass and in contact with the U-shaped hinge part . To provide contact of the locking element, the hinge part of the latter must be made in the form of a fork.

The disadvantage of this design is the insufficient reliability of the fixation due to the requirements of increased accuracy of installation of the locking element, requiring additional processing of the door leaf and fixing the locking element.

Known hinge joint connecting the fixed and pivoting elements pivotally interconnected by means of plate levers mounted on axes and forming a fixed link with fixed and pivoting elements, and mounted on the pivoting element

a latch with a spring-loaded locking element for fixing the door in the closed position, the latch is made in the form of at least one spring-loaded ball mounted in the body of the rotary element on the side of the plate lever so that in the closed position the plate lever contacts its side with the ball and is located between it and bottom of the rotary element. Spring-loaded balls can be mounted on both sides of the leaf lever. However, such a hinge provides a relatively low opening force. And the increase in spring stiffness leads to rapid wear of the lateral surface of the plate lever.

The aim of the invention is to increase the reliability of fixing the door in the closed position.

This goal is achieved in that in the hinge for the door leaf, which contains the fixed and pivoting elements pivotally interconnected by means of plate levers fixed on the axes and forming a four linker with the fixed and pivoting elements, and a latch mounted on the pivoting element at least one spring-loaded locking element for fixing the door in the closed position, the latch is made in the form of a slider mounted in the body of the rotary element on the side of the plate lever and springing parallel thereto, wherein the side surface of the fixed member, docked present inside the rotary member, a projection, and on the slider, the corresponding stop element. The protrusion function on the lateral surface of the fixed element is performed by the end of the axis movably connecting the fixed element and the leaf lever. The latches are installed in the body of the rotary element on both sides. In addition, the protrusion on the lateral surface of the fixed element is performed by the end of the axis movably connecting the fixed element and the leaf lever.

The claimed hinge hinge differs from the known one in that the latch is made in the form of a slider mounted in the body of the rotary element on the side of the plate lever and spring-loaded parallel to it, moreover, a protrusion is made on the side surface of the fixed element extending into the inside of the rotary element, and on slide - the corresponding locking element,

Fig. 1 shows a hinge joint in an open state, a top view; Fig. 2 is a cross-sectional side view in an open state; Fig. 3 is a sectional side view in a closed state (the fixed element is shown schematically); figure 4 is a section bB in figure 2; figure 5 - section bb in figure 2; figure 6 - sliders, isometrics.

The hinge hinge contains a pivot 1 and a fixed 2 elements, pivotally interconnected by means of plate levers 3.4, mounted on axes 5,6,7,8 and forming a four-link with them. The rotary element 1 is made in

5 is a glass fixed in the cavity of the door. In the body of the rotary element 1, on the side of the leaf lever 4, sliders 9 are installed, which are mirror images of one another, loaded with springs

0 10 in the plane parallel to the plane of movement of the plate arm 4. On the side surface of the fixed element 1, going into the inside of the movable element 2 (see Fig. 3) protrusions 11 are made, and

5 on the sliders 9 — their corresponding locking elements 12. The springs 10 are placed in the sliders 9 in special niches 13 and are installed together with the sliders 9 in the grooves in the body of the rotary element 1 and abut against one side of its wall and the other end against the surface 14 of the niche 13. The cover 15 secures the sliders 9 from falling out and is for them one of the guide surfaces. The fastening of the cover 15 to the movable element 5 is carried out by any known method.

The functions of the protrusions 11 on the fixed element 2 are performed by the ends of the axis 6. movably connecting the fixed element 2 and

0 outer plate lever 4.

The loop hinge works as follows. When closing the door leaf, the pivoting element 1 with the locking elements located therein, spring-loaded with sliders 9, rotates relative to the fixed element 2. The protrusions 11 on the fixed element 2 press on the locking elements 12 of the sliders 9. In this case, the sliders 9 are moved away

0, the spring 10 and the protrusions 11 extend under the locking elements 12, which prevent the loop from opening freely.

When opening the door, the protrusion 11 on the movable element 2 should move

5, locking elements 12, for which it is necessary to compress the springs 10.

The configuration of the locking elements 12 and the force of the springs 10 are selected so as to provide easy closing and the required opening force of the door.

Claims (3)

The implementation of the lock of the proposed design improves the performance of the hinge, increases the reliability of fixing the door in the closed position. SUMMARY OF THE INVENTION 1. A hinge for a door leaf comprising fixed and pivoting elements pivotally interconnected by plate levers mounted on axles and forming a four-link with a fixed and movable element, and a latch with at least one spring-loaded locking means for fixing the door in the closed position, characterized in that, in order to increase the reliability of fixing the door in the closed position, the latch is made in the form of at least one wow half a zoon mounted in the body of the rotary element on the side of the leaf lever and spring-loaded parallel to it, moreover, at least on one side of the stationary element entering the inside of the rotary element there is a protrusion, and a locking means interacting with it on the slider. 2. The hinge according to claim 1, characterized in that, in order to increase the durability of the work due to a more even load distribution, the latch is made of two parts placed in the body of the rotary element symmetrically with respect to its longitudinal axis. 3. A hinge according to claim 2, characterized in that the protrusions on the lateral surfaces of the fixed element are formed by the ends of the axis connecting the plate arm to the fixed element. / 2 FIG. / 1784061 4 s & / 2 9 1 - F ig. 5 /5 / 2 9
