Description

The utility model relates to furniture, in particular to drawers made of wood material, which are installed in cabinet furniture and are intended for storing items.

Drawers are a movable part of furniture that can be pulled out and pushed in along guides, providing convenient access to the contents.

Often, drawers are made from wood material such as MDF (medium density fiberboard), which is made by pressing wood chips and binders under high pressure and temperature. MDF is a popular material for furniture due to its strength, dimensional stability, environmental friendliness, and affordability.

Most often, the design of a drawer made of MDF includes a bottom, front and back walls, as well as side walls. These elements are fastened together using glue, screws or other fasteners.

To ensure smooth sliding and retracting of the drawer, guides are used, which are attached to the side walls of the drawer and the corresponding elements of the furniture body.

MDF drawers can be equipped with a variety of additional elements such as shelves, dividers, drawers within a drawer and other organizational methods that help organize the contents and make items easier to access.

When making MDF drawers, various surface treatments such as lamination, veneering, painting or staining can be used to give them an aesthetic appearance and protect them from damage.

A pull-out drawer is known (patent RU 2560326, published 20.08.2015), which comprises a side wall of the pull-out drawer made in the form of a hollow profile, a wall of the pull-out drawer made of wood material and a fitting part fixed to one of both end sides of the wall of the pull-out drawer, with the help of which the wall of the pull-out drawer is connected to the side wall of the pull-out drawer, wherein the side wall of the pull-out drawer has a recess for placing the fitting part.

Additionally, the side wall of the drawer, made in the form of a hollow profile, is made of metal or plastic.

This design is complex and labor-intensive to manufacture and has a number of disadvantages that prevent long-term use of the product with the specified drawers, due to the manufacture of some parts from metal sheets (prone to corrosion).

The prototype is a pull-out drawer containing a front panel, a bottom and a back wall, as well as two side panels, distinguished by the fact that each of the side panels is made of plastic and has holes for fastening the back wall and the bottom of the drawer with screws, holes for fastening the front panel with screws, holes for fastening the side panel to the guide with pins.

This design is easy to manufacture, however, when making such a box from MDF and other similar materials (chipboard), which consist of wood chips and a binder, when screwing a screw or any threaded fastener into the material, especially if this is done without pre-drilling, there is a risk of delamination or cracking of the material, which can lead to a decrease in the strength and aesthetic appearance of the box.

When fastening with threaded fasteners, the heads of the fasteners remain visible on the surface of the box, which can negatively affect the appearance of the product. To hide the heads, it is necessary to use fasteners with a low head, which require pre-drilling at a certain angle, which complicates the fastening process.

Fastening with threaded fasteners can weaken the strength of the drawer assembly, especially if the fasteners are not driven deep enough into the material or if they are located too close to the edges of the parts.

In addition, fastening elements with threaded fasteners requires the use of a tool (screwdriver, screwdriver), which complicates the assembly process.

Because of these disadvantages, alternative fastening methods may be preferable for making drawers from MDF and other similar materials.

One of the technical results of the claimed utility model is ease of assembly.

The specified technical result is achieved due to the fact that the drawer contains a front panel, a bottom, a back wall, two side panels, and the side panels and back wall are made of MDF; in the front panel, two side panels and back wall, there are holes in which plastic dowels are installed, serving as fastening elements for connecting the elements of the drawer to each other.

The drawer is illustrated with drawings.

Fig. 1 shows a general view of the box in a disassembled state,

where 1 is the facade panel;

2 - sidewalls;

3 - rear wall;

4 - bottom;

5 - plastic dowels.

Fig. 2 shows a general view of the box in an assembled state.

Connecting MDF parts with plastic dowels will allow you to create strong and precise connections without the need for glue or additional fasteners and auxiliary tools. This simplifies the assembly process and reduces the time required to make furniture.

Plastic dowels in wood furniture provide high precision of dimensions and geometry of parts, which leads to quick assembly of the product without the use of special devices. This is especially important for furniture with facades and doors, where any minor deviations from the dimensions can lead to incorrect operation or appearance of the product.

Using plastic dowels will create strong and durable connections that can withstand significant loads and bends.

Unlike wooden ones, plastic dowels do not react to changes in humidity and temperature, which in turn will facilitate the ease of assembly of MDF boxes.

Plastic dowels are easy to install, making the assembly process easier. Wooden dowels may require more effort to install, as they tend to warp and may be more prone to delamination or damage during installation, creating additional challenges during assembly.

To connect parts made of MDF using plastic dowels, holes are pre-drilled in the elements to be connected.

Furniture made of MDF, due to the specificity of the material, is easy to reassemble, if the fastener is selected correctly. When assembling furniture from MDF, a minimum number of fasteners is required, which reduces assembly time and reduces the risk of damage to the material.

Thus, Fig. 1 shows a general view of the box, where elements 1-3 are made of MDF wood fiber board, and element 4 can be made of any material, for example plywood.

Elements 1-3 are connected to each other using plastic dowels.

The number of plastic dowels for connecting parts may vary depending on the degree of loading of the boxes.

Moreover, in the rear wall 3 dowels are installed in the side end surfaces.

Sidewalls 2 are connected to the front panel 1 with their front end surfaces, therefore, holes for plastic dowels are made in the front end surfaces. Connection to the rear wall 3 is achieved by adjoining the side surfaces to the side end surfaces of the rear wall 3.

This connection of structural elements will allow the assembly of the product to be carried out most simply and quickly.

Bottom 4 can be secured with plastic dowels inserted into pre-drilled holes in the side walls and bottom of the drawer. It is possible to install element 4 in grooves cut in the bottom of the side walls of the drawer and secure it with tenons protruding from the bottom of the front panel of the drawer. It is possible to screw it to the side walls and front panel of the drawer with screws or nails.

The presented figures, description of the design and use of the box do not exhaust the possible design options and do not limit the scope of the utility model in any way. Other design options are possible within the scope of the claimed formula.

The implementation of the utility model allows solving the stated technical problem and ensuring the achievement of the stated technical result.

The proposed technical solution, which has constructive unity, implements a common functional purpose (functional unity).

The prior art does not contain an analogue characterized by features identical to all essential features of the claimed utility model.

The applicant tested the proposed device, which confirmed its purpose, feasibility and operability, and therefore the claimed utility model complies with the patentability requirement of “industrial applicability”.
