Description

The invention relates to the design of furniture, namely to shelving systems for storing items in the home or commercial sector of the economy and can be used as a shelving for placing industrial and household products, equipment, exhibits, books, archival documents, as well as for intra-shop storage of materials in production, for equipment of warehouses and similar premises.

A collapsible rack is known from the prior art (RU 2285439 C1, patent holder “ZAO NPO Proektspetstechnika” (RU), 03/16/2005). The rack consists of shelves that are located one above the other, side racks made in the form of frames, a back wall and lattice doors. Also, the shelves are hinged to the rear wall with the ability to occupy horizontal and vertical positions, and the side racks are fixed to the rear wall with the ability to rotate around a vertical axis and fix the shelves in a horizontal position. This design of the rack allows you to increase operational capabilities, lighten the design, and also reduce the complexity of use.

A disadvantage of the known rack is that the known rack includes a back wall, which increases the amount of materials required to assemble the rack and accordingly increases the cost of constructing the rack. In addition, the racks of such a rack have a frame rather than a solid structure, through which stored items spill out, which reduces storage density. Also, the frame design increases the cost of the rack due to a greater number of technological operations during manufacturing. In addition, such a design does not provide for adjusting the height of the shelves and changing their number without disassembling the rack, as well as the presence of vertical dividers that limit items falling out to the side and mixing dissimilar items among themselves.

A folding rack is known (RU 2438550 C1, patent holder "Limited Liability Company "P&G Print" (RU)", 06.23.2010). The folding rack contains racks that form the continuous side walls of the rack. In this case, each rack is connected to the rear wall of the rack, or each rack is made integral with the rear wall and is connected to it along the bend line between them, or each rack is connected to the rear wall by another means that allows the rack to rotate in a horizontal plane relative to the rear wall. Between the racks there are shelves, each of which has a box-shaped shape and its sides along the perimeter have flanges in which holes are made, while on the sides of the shelf facing the rear wall and the racks there are protrusions elongated along the side of the shelf, located in the elongated holes of the racks and the back wall. Each rack has additional holes located below the elongated holes of the rack, and fasteners are located in the holes of each flange of the shelf adjacent to the rack, and in the holes of the rack adjacent to this flange. At the same time, a second version of the folding rack has also been announced. The claimed group of inventions makes it possible to reduce the weight of the rack and increase ease of use.

The disadvantage of the known rack is that the rear wall is used as a mandatory structure of the rack, which gives stability to the racks from deforming loads and misalignment. The presence of a rear pillar increases the cost of the design. Also, this rack does not require the use of 1 rack for two sections at once. Also, this design of the rack does not allow flexible changes in its height. The design involves the use of only soft material: cardboard or plastic. When using hard materials (plywood, wood boards), it is impossible to make pillars from the rear wall from a single solid material, so it is assumed that furniture fittings (hinges) will be used, which greatly increases the cost of the structure. In addition, this design does not allow you to adjust the height of the shelves without unloading and disassembling the rack (it is necessary to move the walls apart to pull out and rearrange the shelves).

The closest to the declared group of inventions is a collapsible rack (RU 2242908 C1, patent holder "State Enterprise Ryazan Plant "Banktekhnika" (RU)", 04/03/2003). The invention ensures the creation of a simple compact stable structure of a rack with optimal weight of its parts, speed of assembly, ease of transportation and operation, reduction of defects and manufacturing costs, increased reliability and load-carrying capacity of the structure. A collapsible rack includes side and/or intermediate racks with longitudinal and transverse elements, rear walls of sections, removable shelves and/or connecting shelves made of removable box shape, front panels for each section, fasteners for forming sections with cells, chambers, niches. Connecting shelves and/or intermediate posts are means of intersectional connection, respectively, to increase the length and/or height of the rack. The side and intermediate posts have walls and partitions fixed between the longitudinal and transverse elements. The use in the design of side and intermediate racks of longitudinal and transverse elements made in the form of pipes with holes, shelves and box-shaped connecting shelves with holes, and front panels makes it possible to optimally unify the prefabricated connection of sections, ensure simplicity and speed of installation on site of the rack operation, compactness storage and transportation in disassembled condition.

The disadvantage of the known rack is that each section is made of load-bearing modules, which are metal frame structures with the interconnecting space of the frame filled with sheet metal partitions. Because of this design, the rack is expensive to manufacture and difficult to assemble and operate. In addition, such a rack does not have the ability to adjust the shelves in height, which reduces storage density.

Thus, all prefabricated racking systems known from the prior art for the purpose of ensuring the stability of racks are made either of heavy and expensive materials, such as metal, wood boards 16-25 mm thick (chipboard, plywood, MDF, etc.), or contain an additional element is the back wall, which increases the weight and increases the cost of production and the cost of the racks.

In addition, known racks do not simultaneously provide 5 consumer properties that directly affect storage density:

a) modular design in width;

b) independent adjustment of each individual modular section in height;

c) placing any number of shelves without disassembling or unloading the rack;

d) height adjustment of shelves without disassembling or unloading the rack;

e) the presence of continuous vertical dividing walls that ensure vertical storage of items and limit the mixing of dissimilar items among themselves. Typically, this problem is solved by using additional packaging, which reduces storage density, accessibility of items and increases the cost of the storage system due to the cost of packaging.

The absence of properties in points a) and b) does not allow placing the maximum amount of shelving capacity in rooms of irregular geometric shape. The lack of properties in points c), d) and e) does not allow placing the maximum possible number of items inside the shelving volume with orderly access.

Thus, the objective of the claimed group of inventions is to solve these issues.

The technical result achieved by the claimed invention is to increase the efficiency of using room volume and storage density, while simultaneously ensuring the lightness and stability of the structure.

The total cost of storing items on a racking system consists of three indicators: the cost of producing the rack itself, the efficiency of the racking volume using the space of the room, and the volume of items that can be stored in the racking volume. The cheaper the cost of production and logistics of the rack, the more rack volume is placed in the volume of an irregularly shaped room, and the more items are placed in the rack volume, the lower the total storage cost.

The declared technical result is achieved due to the fact that the modular collapsible racking system includes vertical modular sections, the main parts of which (wall-rack panels and shelves) are made of thin material, 6-8 mm thick. In particular embodiments, such materials as plywood, oriented strand board, monolithic polycarbonate, and organic glass can be used as the thin material from which the parts of the racking system are made. Choosing a material that is readily available for purchase and at the same time cheap, such as plywood, allows you to reduce the cost of producing a rack. In this case, the thickness of the wall-racks and shelves of 6-8 mm is important, since thanks to this thickness it is possible to create a lightweight and inexpensive rack, thereby reducing the total cost of storing items on the rack system.

Modular sections consist of vertical wall-racks formed by panels, horizontal shelves and rigid steel jumpers between the wall-racks of the modular section. The wall-rack panels are perforated on both sides, with one row of holes on each side, on the front and back sides, with vertical rows of holes with the same pitch in the range of 30-100 mm.

Panels of wall racks are connected overlapping, using a screw or bolt connection, through perforated holes. In this way, it is possible to adjust the height of the wall-rack and the entire modular section, placing the rack system in rooms of irregular geometric shape, since different modular sections of the same rack system can be of different heights. This way you can get maximum shelving space. In this case, each internal wall-rack is also a wall-rack of the adjacent modular section.

The modular section contains rigid steel jumpers that connect two adjacent rack walls of one modular section through perforated holes at the top and bottom of the modular section, using a screw or bolt connection, forming one modular section of the racking system. Rigid steel jumpers are attached to each wall-rack at two points, thereby ensuring parallelism of the wall-racks and the absence of distortion of the modular section relative to the supporting surface, for example, the floor.

The shelves rest freely on supporting elements, such as pins, bolts, and special plastic elements, which are inserted into perforated holes in the wall-rack panels.

The reinforcing elements are made of the material of the wall-rack panels and are located on the outside of the modular rack system, along the outer walls-racks with their end facing the plane of the wall-racks and have perforations along the entire length to ensure their height adjustment and are attached to the wall-racks through metal corners , through a screw or bolt connection. Reinforcing elements ensure the stability of the outer wall posts by compensating for horizontal deforming forces. The extreme wall-racks, in turn, compensate for the horizontal deforming forces of all the wall-racks of the rack system through the shelves.

According to the second option, the technical result is achieved by creating a modular prefabricated shelving system, which includes vertical modular sections, the main parts of which (wall-rack panels and shelves) are made of thin material, 6-8 mm thick. In particular embodiments, materials such as plywood, oriented strand board, monolithic polycarbonate, and organic glass can be used as a thin material from which the parts of the racking system are made. Choosing a material that is readily available for purchase and at the same time cheap, such as plywood, allows you to reduce the cost of producing a rack. In this case, the thickness of the wall-racks and shelves of 6-8 mm is important, since thanks to this thickness it is possible to create a lightweight and inexpensive rack, thereby reducing the total cost of storing items on the rack system.

Modular sections consist of vertical wall-racks formed by panels, horizontal shelves and rigid steel jumpers between the wall-racks of the modular section. The wall-rack panels are perforated on both sides: on the front and rear sides with vertical rows of holes with the same pitch in the range of 30-100 mm. Along the front side of the panel, the stand-up walls are perforated with one vertical row of holes; along the back side of the panel, the stand-up walls are perforated with two vertical rows of holes.

The wall-rack panels are overlapped through perforated holes, using a screw or bolt connection, adjusting the height of the wall-rack and the entire modular section. In this case, each internal rack wall is also a rack wall of the adjacent modular section, forming a rack system.

The modular section contains rigid steel jumpers that connect two adjacent rack walls of one modular section through perforated holes at the top and bottom of the modular section, using a screw or bolt connection, forming one modular section of the racking system. Rigid steel jumpers are attached to each wall-rack at two points, thereby ensuring parallelism of the wall-racks and the absence of distortion of the modular section relative to the supporting surface, for example, the floor.

The shelves rest freely on supporting elements, such as pins, bolts, and special plastic elements, which are inserted into perforated holes in the wall-rack panels. Through the second outermost row of perforated holes on the back side of the wall-rack panels, two adjacent wall-racks are pulled together with a flexible tie. The flexible screed performs the function of ensuring the stability of the rack walls by compensating for horizontal deforming forces.

In particular embodiments, a cord or mesh or fabric made of woven or non-woven material can be used as a flexible tie for tightening two adjacent wall-racks.

The declared options for a modular prefabricated racking system make it possible to increase storage density and reduce storage costs by reducing the cost of the modular prefabricated racking system itself and due to the absence of the need to use additional containers.

The main parts of the racking system, such as the wall-rack and shelf, are made of flexible and elastic sheet material and are manufactured in one technological operation of cutting and one installation on a machine, for example, 6-8 mm plywood, due to which the cost is significantly reduced. Since the stand-up walls act as vertical dividers, storage density increases due to the fact that items do not fall to the side and are not mixed with dissimilar items.

Thus, the declared modular prefabricated racking system is technologically advanced, simple and cheap, with a high storage density, which is easily and quickly assembled and disassembled. Having low weight and small volume when disassembled, the system is convenient for moving during repeated use.
