RU52682U1 - ASSEMBLY RACK - Google Patents

Abstract

The utility model relates to the construction of a prefabricated rack, which can be used at exhibitions and in shopping centers to demonstrate goods, as well as in offices and residential premises for storing things. The objective of the proposed solution is to simplify the design and assembly technology of the product. To solve the problem in a prefabricated rack containing horizontal supporting plates 1 and supporting vertical plates 2, the horizontal plates at the edges are equipped with two rows of grooves, and the supporting plates have two pairs of cuts, from ends to the middle, which allow you to reject different parts of the plates in opposite directions with hooks at the ends, and insert them into the corresponding grooves in the shelves.

Description

The utility model relates to the construction of a prefabricated rack, which can be used at exhibitions and in shopping centers to demonstrate goods, as well as in offices and residential premises for storing things.

Design options for prefabricated racks are presented in the book "Das Internationale Design Jahrbuch, 1998/1999." The William Sawaya shelving on page 55 consists of l-shaped plates fastened together and made of plywood and installed at an angle to each other. The rack has an original appearance, but is difficult to manufacture and assemble. Since for the manufacture of plywood l-shaped plates, special equipment is required and considerable time is required.

Another rack (closest to the one offered) from the same source, p. 51, authors Christopher und Fernando Rihl, consists of plates that have slots in different places, one on one side of the plate, others on the opposite. The plates are interconnected crosswise, with each of the plates being inserted into the slot of the other. The rack has a simpler look, it is easier to manufacture, but it has much less rigidity and strength than the counterpart on page 55. The components of the rack are fastened only due to the frictional force, as a result of which loosening of the joints is possible.

The objective of the proposed solution is to simplify the design and assembly technology of the product.

To solve the problem in a prefabricated rack containing horizontal supporting plates and supporting vertical plates, the design of the plates has been changed. The horizontal plates at the edges are provided with two rows of cutouts of variable width, and the support plates are made with vertical cuts, two from the top edge to the middle and two from the bottom, thereby forming six flexible petals of different widths with the possibility of rejecting the petals in different directions.

Additionally, at the end of each petal, two horizontal slots are formed, forming hooks.

This design allows you to assemble the rack from two unified flat parts without the use of any fasteners, adhesives and complex assembly equipment.

The proposed rack is illustrated by drawings, which show:

figure 1 - General view of the rack.

figure 2 is a front view of the rack.

Figure 3 - types (patterns) of composite elements.

The proposed rack consists of horizontal carrier plates 1 and vertical support plates 2. The carrier plates 1 at the edges and in the center are equipped with two rows of grooves of variable width 3, each with three grooves. Support plates 2 at the edges above and below have two pairs of vertical cuts, which are made from the ends to the middle of the plate. The cuts are made so that the middle part of the plate 5 (shown by hatching) and six flexible petals are formed. At the ends of the petals are

hooks 4 formed by two horizontal slots symmetrically located relative to the center of the petal. The hooks 4 are necessary for connecting the support plates 2 with the supporting plates 1 (figure 3).

On a long carrier plate 1, depending on the planned load on it, notches can also be made in the middle part of the plate.

The number of cuts in a row can be more than three. This will allow the support plates to be displaced relative to the supporting ones.

The rack is assembled as follows.

The two extreme lower lobes of the base plate deviate in one direction, and the middle lower lobe in the other. In this position, the deflected petals are inserted into the wide parts of three of the six extreme notches of the lower carrier plate 1, under the action of the elastic force of the petals, the hooks 4 extend into the narrow parts of the notches of the carrier plate 1, thereby forming a reliable elastic connection of the parts. When installing the support plates of the third tier, their lower deflected petals are inserted into three free of six slots in the corresponding row of the second shelf. For complete assembly of the product, the entire process is repeated many times depending on the number of shelves in the kit. If necessary, the support plates are mounted in the middle part of the bearing plates, depending on the working load on the product.

Bearing plates can be made of polymer, plywood, metal, metal-polymer sandwich panels.

Support plates may be made of

polymer, plywood, wood-and-metal sandwich panels.

The design of the rack allows you to quickly and easily assemble the rack of the required height in the right place.

For the manufacture of parts of this rack only equipment for cutting sheet materials is necessary, which is much simpler and cheaper than the equipment necessary for the manufacture of the prototype. Due to the simplicity of the parts, they can be easily transported and stored unassembled.

Claims (2)

1. A prefabricated rack containing horizontal supporting plates and supporting vertical plates, characterized in that the horizontal plates at the edges are provided with two rows of notches, and the supporting plates are made with vertical cuts from the ends to the middle, forming deflectable petals with the possibility of their interaction with the notches of horizontal plates . 2. A prefabricated rack according to claim 1, characterized in that the hooks are made at the ends of the petals for their reliable fastening in the notches of the bearing plates.
