Description

The invention relates to collapsible racks, trade and storage equipment and building structures and can be used in the production of warehouse, trade, advertising and specialized collapsible equipment.

The well-known "automated storage rack" (see AS No. 1736863. Cl. B65G 1/02, A47B 57/00. Publ. 05/30/1992, Bull. No. 20), containing racks placed in rows with a vertical row located next to with the same pitch of rectangular holes each, beams with brackets at the ends having each vertical row of rectangular holes located with the same pitch. In addition, the racks are connected to the brackets by means of a special separate element made in the form of a hook.

The well-known "shelving collapsible" (see certificate for utility model No. 8220. Cl. A47B 47/02. Publ. 11/16/1998), containing a rack with side surfaces and a back wall, which contains two rows of holes along the length racks made in the form of a rectangular trapezoid, as well as a square with two shelves, mounted on a beam. On one of the shelves there are holes matching the rack holes. In addition, the square is mounted on a rack with a connecting element.

The reasons that impede the achievement of the technical result indicated below when using known racks include the fact that in known cases, additional fasteners are used when attaching to the rack of the longitudinal shelves, and the design of the fastening nodes of the known shelves does not provide a tight and rigid connection of the racks with the shelf fastening elements. This, in turn, determines the non-rigidity of the entire prefabricated rack structure and its instability during operation.

In addition, the design of the longitudinal beams does not provide for changes in the distances between the uprights and for strengthening the load-bearing capacity of the beam during the operation of the racks.

The claimed invention consists in the fact that a collapsible rack of commercial and warehouse equipment and building structures contains at least two vertical racks equipped with through grooves, beams with brackets at the ends. Moreover, each bracket is equipped with a special fastening device in the form of a hook and is fixed with its back on a vertical rack, according to the invention, the fastening device is made in the form of an L-shaped bent down element, and a beam made of at least one element is made in the form of an I-shaped bent open profile moreover, the width of one shelf of the profile is less than the width of the other shelf.

The essence of the invention lies in the fact that (option 1) a beam made of at least one element is made in the form of an I-beam bent open profile, and the width of one profile shelf is less than the width of the other shelf.

In option 2, one of the brackets is attached to one of the two beams, located with a narrow shelf up, and the other bracket is attached to the other beam, located with a wide shelf up, and the beams are inserted into each other with their free ends.

In option 3, each of the brackets is attached to one of two beams located with a narrow shelf up, and the beams themselves, with their free ends, are inserted into the third beam, which is located with a wide shelf up.

The through grooves of the uprights are made in the form of rhombic holes having a guide and a working surface, the guide surface being made at an angle of more than 0 to 45 degrees, and the working surface is at an angle of more than 0 to 90 degrees relative to the side surface of the vertical rack. In addition, the L-shaped downwardly curved fasteners are made of bracket material in the form of a truncated wedge having a working surface and made at an angle of more than 0 to 45 degrees relative to the back of the bracket, and the working surface of the truncated wedge is made at an angle of more than 0 to 90 degrees relative to the side surface of the bracket, and the length of the working surface of the truncated wedge of the fastener is less than the length of the working surface of the through groove of the vertical rack. The angle of inclination of the working surface of the through groove and the working surface of the L-shaped bent downward fastening element should be the same.

The use of the invention provides the following technical result:

- increasing the versatility of the design,

- increasing the stability and reliability of the position of collapsible racks, trade and storage equipment and building structures,

- simplification of the design of the connecting elements,

- increase the service life of the connecting elements.

The specified technical result in the implementation of the invention is achieved by the fact that the connection of elements of collapsible racks, trade and storage equipment and building structures, containing at least one vertical rack, equipped on the front side with through grooves, brackets equipped with L-shaped downward curved fasteners and the brackets are fixed with their back on a vertical rack.

The peculiarity lies in the fact that (option 1) a beam made of at least one element is made in the form of an I-beam bent open profile, and the width of one profile shelf is less than the width of the other shelf.

In option 2, one of the brackets is attached to one of the two beams, located with a narrow shelf up, and the other bracket is attached to the other beam, located with a wide shelf up, and the beams are inserted into each other with their free ends.

In option 3, each of the brackets is attached to one of two beams located with a narrow shelf up, and the beams themselves, with their free ends, are inserted into the third beam, which is located with a wide shelf up.

The through grooves are made in the form of rhombic holes having a guide and a working surface, the guide surface being made at an angle of more than 0 to 45 degrees, and the working surface is at an angle of more than 0 to 90 degrees relative to the side surface of the upright. In addition, the L-shaped downwardly curved fasteners are made of bracket material in the form of a truncated wedge having a working surface and made at an angle of more than 0 to 45 degrees relative to the back of the bracket, and the working surface of the truncated wedge is made at an angle of more than 0 to 90 degrees relative to the side surface of the bracket, and the length of the working surface of the truncated wedge of the fastener is less than the length of the working surface of the through groove of the vertical rack. The angle of inclination of the working surface of the through groove and the working surface of the L-shaped bent downward fastening element should be the same.

Collapsible racks of trade and warehouse equipment and building structures consist of a vertical intermediate rack 1, a vertical end rack 2, brackets 3, beams 4-6, through grooves 7 on the racks 1 and 2 in the form of rhombic holes having a guide surface 8 and a working surface surface 9, brackets 3, equipped with L-shaped bent down fasteners 10 made of bracket material in the form of a truncated wedge and having a working surface 11.

The guide surface 8 of the through grooves 7 is made at an angle α = 6 ° (the optimal value for this design), and the working surface 9 is at an angle β = 45 ° (the optimal value for this design) relative to the side surface of the vertical strut.

L-shaped bent downward fastening elements 10 are made at an angle γ = 5 ° (optimal value for this design) relative to the back of the bracket, and the working surface 11 is at an angle β = 45 ° relative to the side surface of the bracket 3. Moreover, the angle of inclination of the working surface 9 of the through groove 7 and the working surface 11 of the fastener 10 should be the same.

The device operates as follows.

Option 1. A rigid structure consisting of a beam 4 and two brackets 3, is connected to two racks 1 and 2, and in brackets 3 made at least one L-shaped bent downward mounting element 10. In order to increase stability and reliability of the position of the structure, the number fasteners 10 on the brackets 3 should be increased. After combining the L-shaped bent down fasteners 10 with the through grooves 7, the brackets 3 fall down. In this case, the fastening elements 10 slide along the guiding surfaces 8 of the through grooves 7 and provide preliminary preloading of the rear sides of the brackets 3 to the side surfaces of the vertical posts 1 and 2. At the same time, the L-shaped bent down fasteners 10 made at an angle γ = 5 ° relative to the back of the brackets, contribute to the compression of the brackets 3 to the front surfaces of the uprights 1 and 2.

When connecting the working surface 11 of the fastening element 10 with the working surface 8 of the through groove 7, the fastening element 10 and, consequently, the bracket 3 are displaced along the working surface 8 of the through groove 7 in the direction of convergence of the rear side of the bracket 3 with the side surface of the vertical rack 1 or 2. It should be noted that the greater the vertical load presses on the beam 4 and thereby on the bracket 3, the stronger the bracket 3 is adjacent to the vertical strut 1 and 2.

The proposed design of the connecting elements increases the stability and reliability of the position of collapsible racks, trade and storage equipment and building structures due to the constant contact of the back of the bracket with the side and front surfaces of the upright.

The absence of additional parts connecting the vertical uprights with brackets and transverse beams simplifies the design of connecting elements and the entire structure as a whole.

The proposed design of the L-shaped downward bent fastener and the through groove in the form of a rhombic hole increase the service life of the connecting elements by compensating for the gaps formed during the wear of the connecting elements: the length of the working surface of the truncated wedge of the fastening element is less than the length of the working surface of the through groove of the vertical rack.

Option 2 (see figure 3). The brackets 3 are rigidly mounted with beams 4 and 5, and then attached to the posts 1 and 2 (for the description of the connection, see option 1). Moreover, the beam 4 is made in the form of an I-beam bent open profile with an upper arrangement of a wide shelf (see Fig. 2), and a beam 5 - with an upper arrangement of a narrow shelf (see Fig. 5). In addition, the free ends of the beams 4 and 5 are inserted into each other (see figure 4). This design allows you to change the distance between the racks 1 and 2 at the request of the user during operation of the rack.

Option 3 (see Fig.6). The brackets 3 are rigidly mounted with beams 4, and then attached to the posts 1 and 2 (for the description of the connection, see option 1). Moreover, the beams 4 are made in the form of an I-beam bent open profile with an upper arrangement of a wide shelf (see figure 2). In addition, the free ends of the beams 4 are inserted into the beam 6, made in the form of an I-beam bent open profile with an upper arrangement of a narrow shelf (see figure 5). This design allows you to change the distance between the racks 1 and 2, as well as to strengthen the bearing capacity of the beam by creating a prefabricated structure of three elements at the request of the user during operation of the rack.

Thus, the foregoing description indicates the fulfillment of the following set of conditions when using the claimed invention:

- a tool embodying the claimed invention, in its implementation is intended for collapsible racks, commercial and warehouse equipment and building structures and can be used in the production of warehouse, commercial, advertising and specialized collapsible equipment;
