Description

CONSTRUCTION BRACKET

The utility model relates to the supporting elements of special furniture and can be used in prefabricated shelving for fastening shelves, for example, in trade pavilions, exhibition halls, etc.

Known bracket for prefabricated structures 1, made of sheet material and comprising a bearing part with a supporting edge and a restrictive collar and a tail part consisting of grippers made in the form of elastic petals, bent during assembly, namely, when the tail part of the bracket is inserted into the grooves of a vertical racks.

The disadvantages of this bracket are the design complexity of the tail and the inability to install the bracket at various angles to the vertical.

Closest to the proposed technical solution is the well-known bracket for prefabricated structures, for example, shelving 2, made of sheet material in the form of a trough and comprising a bearing part with abutment edges and a tail part consisting of grippers with fixing grooves.

The disadvantages of this bracket are the complexity of manufacture due to the need for stamping and bending operations, as well as limited functionality due to the inability to install the bracket at different angles to the vertical.

These disadvantages are eliminated in the proposed bracket for prefabricated structures made of sheet material and comprising a bearing part with a supporting edge and a tail part consisting of grippers with fixing grooves, in that the tail part contains upper, middle and lower grips in the upper and

the lower grip is made of external and internal locking grooves, and on average one locking groove, and the internal locking groove of the upper grip, the locking groove of the middle grip and the external locking groove of the lower grip are placed on the first axis perpendicular to the supporting edge of the supporting part, and the internal fixing groove of the upper capture, fixing the groove of the middle capture and the internal locking groove of the lower capture are placed on the second axis,

located in relation to the first axis at an angle of OS.

Moreover, in the proposed bracket, the intersection point of the first and second axes is located on the supporting edge of the locking groove of the middle grip, and the angle

the intersection of the first and second axes satisfies the condition of OS 10 ° - 45 °.

The specified set of design features of the proposed bracket allows you to simplify the manufacturing technology, eliminating the need for stamping and bending, and also provides the ability to install the bracket at different angles to the vertical (at an angle of 90 ° and an additional angle (90 + a) °), thereby changing the angle of inclination shelves for demonstration of exhibits or goods located on them.

In addition, a feature of the proposed bracket is that on the supporting edge of the supporting part of the bracket there are three fixing grooves on

equal distance from each other, and the width of the middle groove Osr. satisfies

condition Fr. 2 okr., Where okr. - the width of the extreme locking grooves.

These additional design features allow you to quickly and reliably install flanged shelves on the bracket made of sheet material with a thickness of O, which corresponds to the width of the bracket grooves as follows

way: About O. - A,

where A is the value of technological tolerance for the manufacture of fixing

The essence of the utility model is illustrated by drawings, where:

- in FIG. 1 shows a bracket mounted in a horizontal position (at an angle of 90 ° to the vertical axis);

figure 2 shows the bracket mounted in an inclined position (at an angle (90 + a) °) to the vertical axis);

in FIG. 3 as an example, shows the relative position of the vertical racks of the rack, brackets and shelves during assembly.

The bracket (Fig. 1 and Fig. 2) is made of sheet material and includes a bearing part 1 with a supporting edge 2 and a tail part 3 (the bearing and tail parts in the drawings are separated by a dotted line).

The tail part 3 consists of three grippers: the upper 4, middle 5 and lower 6. In the upper gripper 4, the external 7 and internal 8 fixing grooves are made, in the middle gripper 5 - one fixing groove 9, and in the lower gripper 6 - external 10 and internal 11 fixing grooves.

While the internal locking groove 8 of the upper grip 4, the locking groove 9 of the middle grip 5 and the external locking groove 10 of the lower grip 6 are placed on the first axis 12, perpendicular to the supporting edge 2 of the carrier part 1, and the internal locking groove 8 of the upper grip 4, fixing the groove 9 of the middle grip 5 and the internal locking groove 11 of the lower grip 6 are placed on the second axis 13,

The point 14 of intersection of the first 12 and second 13 axes is located on the supporting edge of the locking groove 9 of the middle grip 5.

In this case, the locking grooves of the grippers are made in such a way that the angle

the intersection of the first 12 and second 13 axes satisfies the condition of OS 10 ° - 45 °.

In addition, on the supporting edge 2 of the carrier part 1 of the bracket, three fixing grooves 15, 16, 17 are made at an equal distance from each other, moreover, the width of Osc.

middle groove 16 satisfies the condition isr. 20kr., Where okr. - width of extreme

fixing grooves 15 and 17.

The tail parts of the 3 brackets are designed to be connected to the mounting racks 18 when assembling the rack by inserting the grippers 4, 5, 6 into the perforations 19 of a rectangular shape made in the front wall of the racks 18 (Fig. 3).

Bearing parts 1 of the brackets are designed to install shelves 20 and 21 on them (Fig.Z).

The bracket is installed, for example, when assembling the rack as follows.

In the rectangular perforations 19 of the uprights 18 previously installed in the vertical position, the grippers 4, 5, 6 of the brackets are inserted at the same level from the base surface (from the floor).

In the fixing grooves 7, 8, 9, 10 and And, the lower edges of these holes should be inserted.

Moreover, depending on the required tilt of the shelves (horizontally or below

the angle of the OS to the horizontal) are located on the vertical axis 12 of the locking grooves 8, 9, 10 or locking grooves 7, 9, 11 (see figure 2).

After this, a sharp movement down the tail part 3 of the bracket with some effort enter into engagement of the locking grooves with the edges of the rectangular holes 19.

The width of the fixing grooves, taking into account the manufacturing technological tolerance, corresponds to the width of the edge of the rectangular perforations 19 (thickness of the front wall of the rack 18), which ensures reliable connection without additional fasteners (screws, bolts or rivets).

After that, the shelves 20 and 21 are installed on the bearing parts 1 of the brackets.

Racks 19 with the brackets inserted into them should be spaced from each other at a distance corresponding to the length of the shelves 20,21.

The shelves 20 and 21 are fixed alternately on two brackets installed at the same height and at the same angle.

The fixing grooves 15, 16 and 17 of the supporting part 1 of the brackets are designed to connect with the flanged edges of the shelves 20 and 21 when assembling the rack (Fig.Z).

The insertion of the flanged edges of the shelves 20 and 21 is carried out in the corresponding grooves 15, 16 and 17 of the supporting part 1, and the sharp movement of the shelves down provides a mechanical connection.

The width of the fixing grooves 15, 16 and 17, taking into account the manufacturing technological tolerance, corresponds to the width of the edges of the shelves 20 and 21 (the thickness of the sheet material from which they are made), which ensures a reliable connection.

Thus, using the proposed bracket assembled one section of the rack, other sections are assembled similarly.

The proposed bracket is made of sheet material (mainly metal) with a thickness that provides the necessary load without structural deformation.

The bracket can be made by various methods, for example, by stamping or processing a metal sheet on numerically controlled machines.

The advantage of this bracket is the simplicity and manufacturability, the ability to install it at two different angles, as well as the lack of need for additional fasteners when installing it in the rack.
