Description

The invention relates to the construction, namely, to the design of the brackets of automatic doors installed, for example, in shops, offices, buildings, etc.

The prior art door bracket for a household appliance (see RF patent 2314400 for an invention, publ. 10.01.2008).

The invention relates to a support bracket for pivoting a door of a household appliance in the form of a cabinet, in particular a refrigerator or freezer.

The door support bracket for the household appliance is made in the form of a cabinet having a support console and a support pin protruding from the support console in the first direction, while the foot of the household appliance extends from the support console to extend the support pin in a second direction opposite to the first direction. The support pin protruding in the first direction in the mounted state of the bracket, at least mainly with its free end, is directed vertically in the direction opposite to the leg. In the support pin there is a cavity for the pin part of the height-adjustable leg. A threaded hole is formed in the protruding fitting of the carrier console.

The prior art system for sliding a sliding door (see RF patent 2568866 for an invention, publ. 20.11.2015).

A system for sliding a sliding door of a wall cabinet comprises a plurality of telescoping nodes and a connecting mechanism that connects one node to another. Each telescoping unit comprises a rail and a sliding member configured to slide along the rail, where the rail engages with the frame of the wall cabinet. The connecting mechanism makes it possible to synchronize the pulling force exerted on the door at various door positions due to the connection of the pulling units by means of the connecting mechanism. This configuration allows you to extend and return the door outward and inward due to the sliding of the sliding element of each node along the rail.

The prior art household appliance containing a hinge with a support bracket (see RF patent 2632037 for the invention, publ. 02.10.2017).

The hinge support bracket is for attaching a door to a housing of a household appliance, preferably a cooling device, comprising a heat-insulated cabinet-shaped housing. The support bracket is mounted on a connecting plate located on a part of the housing. The support bracket is made in the form of a console, at least one long edge of which is curved in the shape of a wing in order to increase its strength. A trunnion is provided, made perpendicular to the support bracket, the hinge support on which the door will be fitted is located at one end of the support bracket. The first of the two holes located in the intermediate part of the support bracket is an adjustment hole that includes a support supporting the support bracket when the support bracket receives the mass of the door and when the support bracket is connected to the connecting plate, both ends of the hole are located in the open part. Thus, the support can be adjusted to the desired height. Another hole is a mounting hole for connecting the support bracket to the connecting plate by means of at least one connecting element. At the other end of the support bracket, there is a landing section and a fixing strip made in the shape of the letter “r”. A positioning hole is provided in the region of the locking bar. In the connecting plate, the shape of which corresponds to the design of the support bracket, there is a locking hole in which the locking bar will enter; in addition, a positioning bar and a mounting hole are provided that will be used to connect to the positioning hole in its extension.

The disadvantages of the prior art technical solutions - brackets are:

- insufficient rigidity;

- brackets are not designed for heavy weight;

- additional holding points are needed to hold the leaf;

- the main load falls on the threaded connection.

The technical results of the claimed invention are: increased stiffness, reliability and strength of the bracket.

The claimed bracket has the following advantages:

- It is designed for heavy weight due to a properly designed interface unit for horizontal and vertical parts;

- has the correct load distribution;

- the ability to hold the sash without the use of additional attachment points;

- the ability to mount at the top without a reference point on the horizontal lower surface of the base (floor).

The technical results of the claimed invention are achieved in that the upper swing door bracket consists of:

- rectangular bases with two holes made along the longitudinal side (axis) of the base for fastening to the horizontal profile and additional fixation to the drive carriages of the automatic door with screws, and one hole along the longitudinal side (axis) of the base for fastening to the upper part of the rotary shaft ;

- a rotary shaft, the diameter of which in the upper part at the attachment point to the base is smaller than the diameter from the opposite lower part of the shaft at the attachment point of the lower attachment element, while in the upper and lower parts along the vertical axis of the rotary shaft, grooves are provided for circlips to fix the two elements fastenings (upper and lower) to the vertical plane of the rotary shaft, while the upper and lower fasteners are made in the form of squares with three holes for fastening to the vertical side profile with screws, and also one hole along the longitudinal axis for connection with the rotary shaft, the connection is obtained with a gap, forming a bearing element.

The features and essence of the claimed invention are explained in the following detailed description, illustrated by drawings (see figures 1 and 2).

In FIG. 1 shows the design of the swing upper bracket for automatic doors.

In FIG. 2 shows the layout of the upper pivot arm in an automatic door.

In FIG. 1 and FIG. 2 the same reference numerals denote the following:

1 - base;

2 - washer;

3 - rotary shaft;

4 - fasteners in the form of squares (upper and lower);

5 - two holes of the base for fastening to a horizontal profile and fixing to the carts of the drive of the automatic door;

6 - hole of the base for mounting to the upper part of the rotary shaft;

7 - three holes of the upper and lower fastening elements to the vertical side profile;

8 - the door.

The base (1) of the bracket (see Fig. 1 and 2) is made of steel St 20 with two holes (5) M6 for fastening the base (1) of the bracket to the horizontal profile and additional fixation to the drive carriages of the automatic door (8) with screws M 10, and one hole (6) with a diameter of D 22 mm for fastening the base (1) to the upper part of the rotary shaft (3) using electric arc welding.

The rotary shaft (3) is made of metal St 20, L 600 mm, the diameter d of the shaft (3) in the place of attachment to the base (1) is 22 mm, and the diameter d of the shaft (3) on the opposite bottom (side) is 25 mm. The rotary shaft (3) has in the upper and lower parts along the longitudinal axis of the recess under the retaining rings for fixing two fastening elements (4) - upper and lower to the vertical plane of the shaft (3).

The fastening elements (4) (upper and lower) are made in the form of two squares and are made of St 20 metal, have dimensions 50 × 37 × 34 mm, have three holes (7) M6 for fastening to the vertical side profile using M6 screws, as well as one hole D 28 mm along the longitudinal axis for connecting to the rotary shaft (3), while the connection is obtained with a gap, forming a sliding bearing element.

The analysis of the prior art made it possible to establish: analogues with a set of essential features that are identical to the essential features of the claimed bracket are absent, which indicates the conformity of the claimed technical solution to the condition of patentability "novelty".

The search results for known technical solutions in order to identify significant features that coincide with distinctive essential features of the claimed bracket, showed that they do not follow explicitly from the prior art, and the influence of distinctive essential features on the technical results indicated by the authors has not been established. Therefore, the claimed invention meets the condition of patentability "inventive step".
