Description

The claimed utility model relates to structural elements of furniture, and can be used to move the shutters of cabinets and shelves for storing and conveniently retrieving various goods.

From the prior art, such mechanisms are known that allow movable doors or shutters to make a rotational movement, for example, a movement mechanism known from patent US2420015A, publ., 05/06/1947, used in the design of filing cabinets. For this purpose, the device is made with a side filing cabinet, in which a plurality of containers, each of which is formed from two right angled side walls fixed on two end walls, which are hingedly mounted in several tiers in an open front support casing in such a way that the containers rotate on 90 degrees outward from the storage location to the access position, in which the containers are partially open through the open side of the body behind its front wall, for this it is necessary to arrange hinges around which the containers are pivotally mounted, at a certain distance inward from the lower front corners of the containers, so that when By swinging containers to open or access positions, the center of gravity of each loaded container does not move too far forward in the housing. In fact, it is necessary to arrange the joints that make up the rod around which the container rotates so that some or all of the containers are at the same level, when open, they will not over-balance the body and cause it to tilt forward on the base.

The disadvantage of the device described in the said patent is that it is complicated in execution and has many parts of complex shape, which are accordingly difficult to manufacture and repair.

Also, as an analogue of the claimed device, a movement mechanism known from BE467545A can be selected, which contains a lever system for lifting the shutters.

The disadvantage of the device is the large number of parts included in it, which also have many joints, which wear out during operation.

The closest analogue of the claimed device can be a refrigerator cabinet, known from the patent

US 10690401 B2, published 06/23/2020, having a storage space formed therein; a door installed in the cabinet for opening or closing; many boxes located inside the storage space and arranged vertically; a lifting drawer located at a lower position than other drawers among the plurality of drawers; a rail assembly located on both sides of the lift drawer so that the lift drawer can slide in or out of the storage space; and a lifting unit rotatably coupled to each of the rail unit and the lifting drawer and allowing the lifting drawer to move up and down by rotating the lifting unit in a state in which the rail unit has been removed.

The disadvantage of the closest analogue is the complexity of the rail mechanism, in which skewing and jamming is not excluded, which reduces the period of the device's maintenance-free period.

The technical result of the claimed utility model is to improve the manufacturability of the device and simplify its design, increase maintainability and increase the period of maintenance-free use.

The claimed technical result is achieved by creating a mechanism for moving the shutters, containing a rod, on which brackets are installed, the number of which corresponds to the number of shutters, while projections are made on the rod, the number of which corresponds to the number of brackets, the bracket is made in the form of a pentagon, the three corners of which are adjacent straight lines , one of the extreme right angles of the bracket is fixed on the rod with the possibility of rotation, and at the other extreme right angle, a lever is rigidly fixed, which is made in the form of a rectangular triangle, continued by a bar with a hole at the end, the bracket also contains elements for fastening to the shutter, fixed in the hole, placed at the intersection of the axes dividing the sides adjacent to the mean right angle in half.

In a particular embodiment, the lever has three attachment points with a bracket.

In one particular embodiment, the fastening elements are made in the form of a screw-nut pair.

In a particular embodiment, the mechanism is equipped with a spring mounted on a rod.

The claimed utility model is illustrated by the following figures:

FIG. 1 is a view of the attachment of the shutter movement mechanism;

FIG. 2 is a side view of the shutter movement mechanism in the closed shutter position;

FIG. 3 is a side view of the shutter movement mechanism in the position with the shutters open;

FIG. 4 is a general view of one of the options for securing the mechanism for moving the cabinet doors in the position with open and closed shutters;

FIG. 5 is a general view of the lever;

FIG. 6 is a general view of the thrust.

The positions in FIG. 1-6 indicate the following:

1 - footwear;

2 - pulling rivet;

3 - lock washer;

4 - screw with a semi-cylindrical head;

5 - threaded rivet;

6 - side wall;

7 - curtain bracket;

8 - thrust;

9 - lock bolt;

10 - lever;

11 - electromagnetic lock;

12 - spring;

13 - base.

The following describes an embodiment of the utility model that does not limit the scope of rights of the claimed utility model.

The shutter movement mechanism contains a rod (8) fixed to the side wall (6) on which the brackets (7) are installed, the number of brackets corresponds to the required number of shutters. On the rod (8) there are rectangular projections on which the brackets (7) are attached, the curtain is attached with the bracket (7) by means of a foot (1), an M6 × 13 foot can be used, an exhaust rivet (2), an M4 × 8 rivet can be used DIN 7337 A2, lock washers (3), in a particular version washer DIN 6798 A2, semi-cylindrical head screws (4) - screw M6 × 30 DIN 7985 Ζ A2 and blind rivets (5) - rivet M6 × 16. The bracket (7) is made in the form of a pentagon, the three corners of which are adjacent straight lines, one of the extreme right angles of the bracket is fixed on the rod with the possibility of rotation, and at the other extreme right angle the lever (10) is rigidly fixed, which is made in the form of a right-angled triangle, continued by a bar with a hole at the end, the bracket also contains fastening elements to the shutter, fixed in the hole located at the intersection of the axes dividing the sides adjacent to the middle right angle in half. The lever (10) has three attachment points with a bracket.

The movement mechanism can also be additionally equipped with a spring (12) mounted on a rod; the whole structure can also be equipped with an electromagnetic lock (11).

The shutter movement mechanism can be used in commercial equipment for easy retrieval of goods, has a low cost and ease of implementation, and the use of available parts increases the maintainability of the mechanism, as well as an increase in the period of its maintenance-free use in conditions of repeated opening and closing of the shutters.
