Description

The invention relates to hardware for doors and can be used in the design and manufacture of cabinets and room doors.

BACKGROUND OF THE INVENTION

From the description of European application EP 1835105 A1, a hardware system is known for a parallel retractable sliding leaf, which contains two upper and two lower outlet brackets, which are, in the mounted state of the hardware system, pivotally mounted, each on the one hand, on a retractable sliding shutter and, on the other hand, in pairs on the two upper running gears moved in the upper guide bar fastened on a separate frame, and, accordingly, on the two lower running carriages moving along attached to the p zdelnoy frame bottom chassis bracket, wherein at least one upper and at least one of the lower diverting brackets - preferably through directed in a direction of closing the sliding flaps vertical crossbar - connected to one another by a vertical boom element to perform synchronous movements efferent arm; for parallel extension of a parallel-releasable sliding sash in a mounted state from a separate frame or its opening and the reverse slide of this sash into the separation frame

The disadvantage of this system is that the upper and lower running plates (guides) are located in the room and are located in front of the wings; Foreign objects may fall into the slats that become an obstacle when opening or closing the sash. Removing these items is often a cause of damage to the running bars. In addition, often to remove these items, it is necessary to dismantle the entire device, which entails great labor costs. This disadvantage can be attributed to the upper and lower outlet arms, which can be bent if foreign objects enter between them and other elements of the system.

These shortcomings are partially eliminated in the system of opening and closing doors, known from the description of the European application EP 0864719 A1. This system contains two guides mounted on the respective doors, and carriages (running elements) placed on them, pivotally connected to supporting rods mounted vertically, each carriage is arranged to move along a corresponding guide, the guide and carriages remote from the doors, configured to moving along a guide remote from the doors, pivotally connected to the corresponding doors, in addition, the system contains support wheels installed in the lower part of each two ri. In this system, the components are out of reach and the accidental ingress of foreign objects into them is excluded.

A serious disadvantage of the known system is that in it the support wheels installed in the lower part of each door move directly on the floor. This movement poses a danger to the user's health, as these wheels can cause injuries when hitting the user's feet. In addition, this system of opening and closing doors has large dimensions due to the execution of guides along the entire width of the doors, as well as due to the implementation of support rods along the entire height of the doors. In this regard, the consumption of materials in the manufacture of this system also increases.

SUMMARY OF THE INVENTION

The task to which the proposed system is aimed is to increase the safety of opening and closing doors and reduce material consumption.

The technical result of the claimed invention is, in particular, obtaining a safe operation of a compact door opening and closing system, in which the adjacent ends of the fully closed doors are located in one plane. Another technical result is that the proposed system can provide opening and closing of doors with a curved shape.

The technical result is achieved by the fact that in the system of opening and closing doors, containing two guides installed on the respective doors, and carriages placed on them, pivotally connected to each other, each of which is made with the possibility of movement along the corresponding guide mounted on the door; and a guide remote from the doors and carriages, arranged to move along a guide remote from the doors, pivotally connected to respective doors; moreover, the carriage made with the possibility of moving along the guides placed on the doors, made with the possibility of fixing their position.

In addition, the system may be further provided with door ejection devices configured to interact with each door.

In this case, the carriages located on the rails mounted on the doors are pivotally interconnected by means of the rocker arm, and the carriages arranged to move along the rail remote from the doors are pivotally connected to the corresponding doors by the rocker arm.

SUMMARY OF THE INVENTION

The claimed door opening and closing system installed on the cabinet comprises two guides 3 mounted on respective doors 1, carriages 4 placed on them, articulated between each other, for example, by means of a rocker arm 5 or other known connector (straps, rods, etc. e.), as well as the guide 6 remote from the doors 1 and the carriage 7, arranged to move along the guide 6 remote from the doors 1.

Moreover, each carriage 4 mounted on the guide 3, which is mounted on the door 1, is arranged to move along the corresponding guide 3 mounted on the door 1. And each carriage 7, made to move on the guide 6 remote from the doors 1, is pivotally connected with a corresponding door 1, for example, by means of a rocker arm 8 (or other known connector, for example, strips, rods, etc.), which is connected to the door by a cylindrical hinge (for example, a hinge). The carriages 4 and 7 can be replaced by rollers pivotally connected to the rocker arms 5 and 8, respectively, however, this embodiment can be applied only to light doors 1 with a small weight, for example, not more than 5 kg.

It is preferable that the door opening and closing system be equipped with door ejecting devices 9 adapted to interact with each door 1. Each door ejecting device 9 is made, for example, in the form of a gas spring mechanism (gas spring) or, which is less preferred due to the increase in mass system, hydraulic spring mechanism, the stock of which is connected to the corresponding door 1.

The carriages 4, made with the possibility of movement along the guides 3 placed on the doors 1, are made with the possibility of fixing their position. In the closed position, each door 1 is supported either on the lower part of the door frame, or, as shown in FIG. 1, by the protrusions 10 on the inner surface of each door 1, on a support plate 11 located in one plane or in a plane parallel to that plane , in which the guide 6. is located remote from the doors. Instead of the protrusions 10, support rollers can be used, and their convergence from the surface of the support plate 11 will be performed almost without friction than in the case of using the protrusions 10. Fixing the position The specified carriages 4 are realized when the corresponding door 1 is open. Part of the weight of the door 1 acts on any of the indicated carriages 4, while part of the weight of the door 1 acts on each rotational element (for example, a roller or bearing) of the carriage 4, preventing it from rotating and move freely along the guide 3 placed on the door 1. In other words, part of the weight of the door 1 acts on the generatrices of the surfaces of all the rollers or bearings, preventing them from rotating and freely moving along the guide 3, placed on two ri 1.

As follows from the above, all the main elements of the door opening and closing system should be located at a small distance from each other, which makes the system compact.

The system of opening and closing doors works as follows.

In the closed position of the doors 1, the protrusions or support rollers 10 are supported on the support plate 11, or each door is supported on the lower part of the door frame, while the position of the carriages 4 is not fixed.

Before starting to open the right or left door 1, the user must press on the outer surface of the door 1 selected for opening. In this case, the inner surface of the door 1 presses on the actuating element of the door ejecting device 9, for example, on the gas spring rod, and the said actuating element pushes the selected door 1 into the direction of its outer surface, as shown in figure 2. The protrusion or the support roller 10 or the door frame will no longer support the selected door 1, and it will hang on the beam 5 and on the beam 8, pivotally connected to the selected door 1, relying on a guide 3 mounted on the door 1, not selected for opening, and on the guide 6 remote from the doors. In this case, the position of the carriage 4 on the guide 3 mounted on the selected door 1 is fixed, as described above in this section of the description, excluding the possibility of moving the specified carriage 4 in the specified guide 3.

Next, the user moves the selected door 1 in the direction of another, not selected to open the door 1, as shown in Fig.2. At the same time, the selected door 1, moving in the indicated direction, pulls the rocker arms 5 and 8. The rocker arms 5 and 8 rotate in hinges and begin to pull the carriage 4 located on the guide 3 mounted on the door 1 not selected for opening, and a carriage 7 pivotally connected to the selected door 1. Thus, the selected door 1, moving on the indicated carriages 4 and 7, opens to the required clearance, for example completely, as shown in Fig.4.

After the user wants to close the selected door, he will begin to move it in the opposite direction. At the same time, the selected door 1, moving in the indicated direction, pulls the rocker arms 5 and 8. The rocker arms 5 and 8 rotate in hinges and begin to pull the carriage 4 located on the guide 3 mounted on the door 1 not selected for opening, and a carriage 7 pivotally connected to the selected door 1. Thus, the selected door 1 moves on the indicated carriages 4 and 7 in the direction from the other, not selected door 1. When the selected door 1 returns to its original, closed position, protrusion or support roller 10 comes on PORN plate 11 and rests on it, or part of the door 1 and the door frame rests at its lower part. In this case, the carriage 4, placed on the guide 3 mounted on the closed door 1, will be in a non-fixed position. The inner surface of the door 1 will approach or enter into contact with the actuating element of the door ejecting device 9 without moving it to a position from which the actuating element may again push the door 1 out.

Thus, due to the fact that all the main elements must be located at a small distance from each other, the door opening and closing system is compact, and due to the fact that all the main elements are located in places remote from the user, the opening and closing system Doors is safe during its operation.
