Description

[0001] The utility model relates to the production of furniture, in particular to the design of an assembly sectional cabinet, and can mainly be used in construction and installation work and renovation of premises for placing and storing various items and tools in it.

[0002] In recent years, modular furniture has become popular and continues to gain popularity. Key factors for its popularity include ease of assembly, functionality, efficient use of available space, and the ability to achieve a variety of spatial configurations.

[0003] The prior art discloses prefabricated furniture structures of various configurations, comprising a bottom, sides, back, front and top panels connected to each other by means of furniture fittings, for example, RU No. 27457, op. 2003; 52681, op. 2006; 96738, op. 2010; 106084, op. 2011; 200265, op. 2020; 2815120, op. 11.03.2024; 2817346, op. 15.04.2024; 2843156, op. 2025. Office pedestal structures are also known, for example, RU No. 2246243, op. 2005; 225479, published 2005; 39051, published 2004; European Patent No. 0875172, published 1998, or transformable pedestal tables, for example, RU No. 16822, published 2001; 2337191, published 2008; No. 238074, published 2025.

[0004] In the cited sources, technical solutions for prefabricated furniture, including cabinets, address issues such as reduced assembly time and increased functionality, facilitating assembly, and preventing frame warping and deformation during use. Furthermore, a key aspect of using prefabricated furniture is ensuring easy access to stored items in the interior compartments, which is essential during construction, installation, and repair work.

[0005] The objective of the claimed utility model is to create a cabinet design with low assembly labor intensity and at the same time expand its functional capabilities, for example, using it as an open cabinet, table, workbench, or shelving unit for temporary and long-term storage of items.

[0006] The technical result that the claimed utility model is aimed at achieving is a reduction in labor intensity during assembly.

[0007] The technical result is achieved in that the cabinet-constructor contains two open-type sections connected to each other, located one above the other, each of which is formed by horizontal shelves with sides and two sidewalls connected to each other, wherein in each shelf mounting holes are made for mating with the sidewalls, and in the lower shelf of the first section there are two holes, and in the lower shelf of the second section - four, in addition, each sidewall of each section is a locking element made of internal, middle and external panels of different sizes, connected to each other with an overlap, wherein on the lower edge of the inner panel there is a central projection for mating the sidewall with the holes of the lower shelf of the first section, and on the upper edge of the panel there are two side projections created with the possibility of embracing them the central projection of the inner panel and mating the sidewall with the holes of the lower shelf of the second section,and the outer panel of the locking element is the outer side of the sidewall for each section.,

[0008] The technical result is also achieved by the fact that the lower shelf of the first section is made with rotary roller supports, and the upper shelf of the second section is made with a lid; that the mounting holes in the horizontal shelves are made through, and on the plane of the lower shelf of the second section they are located evenly along the perimeter of its contour; that the sections are interconnected by fastening elements of furniture fittings; that the side and central projections on the inner panel of the locking element have a U-shape; that the overlapping connection of the panels of the locking element is performed either by screw coupling or by gluing the panels with a tight fit; that the shelves with sides and the sidewalls are made of chipboard, MDF, or laminated plywood of different thicknesses, or from wood with ends treated from the effects of moisture.

[0009] The cabinet-constructor is illustrated by the following figures, where:

[0010] Fig. 1 - general view of the cabinet, in axonometry;

[0011] in Fig. 2 - also with a lid (on the top shelf of the second section);

[0012] in Fig. 3 - the lower shelf of the first section;

[0013] in Fig. 4 - the lower shelf of the second section (A - shelf; B - 4 holes on the plane of the shelf);

[0014] in Fig. 5 - a lock element from the inner, middle and outer panels, in axonometric view (A - view of the inner panel; B - view of the outer panel);

[0015] in Fig. 6 - cover of the cabinet-constructor;

[0016] Fig. 7 - photo of a fragment of the connection of sections with fastening elements of furniture fittings.

[0017] The cabinet-constructor contains: 1 - horizontal panels; 2 - shelf side; 3 - bottom shelf of the first section; 4 - holes in the bottom shelf of the first section. 5 - bottom shelf of the second section; 6 - holes in the bottom shelf of the second section; 7 - inner panel; 8 - middle panel; 9 - outer panel; 10 - central projection of the inner panel; 11 - side projections of the inner panel; 12 - swivel support wheels; 13 - cabinet cover.

[0018] The modular cabinet is a type of prefabricated sectional (modular) furniture made from interconnected panels of different sizes. The panels are made of chipboard, MDF, laminated plywood of varying thicknesses, or wood with treated edges to protect against moisture.

[0019] Assembly is performed on a level surface, maintaining the geometry of the structure and ensuring there are no distortions. The first section of the cabinet-constructor is the base section during assembly. All other sections, starting with the second, are constructed similarly, with similar side panels in the form of a locking element installed in each section of the cabinet. Side panels 2 are screwed onto horizontal panel 1 and secured together at the ends. Two through holes 4 are drilled on the plane of horizontal shelf 3, at both edges, the location and size of which correspond to the central projection 10 of the inner panel 7 of the locking element. A platform (not shown in the figures) is attached to the bottom of the base shelf, to which swivel, support, and self-orienting wheels 12 are bolted and secured with nuts. This creates the basic lower shelf 3 of the first section.

[0020] Each side panel of each cabinet section is a locking element, made as a sandwich of three panels of different sizes (inner 7, middle 8, and outer 9), overlapping each other. The overlapping joint is achieved either with screws or by gluing with a tight fit. The locking element is universal and is suitable not only for the two-section cabinet described, but also for three- or four-section designs.

[0021] The inner panel 7 of the locking element is provided with projections along its edges. One central projection 10 is at one end, while the other has two lateral projections 11 (one on each side of the panel). The location and size of the central projection 10 on the inner panel 7 corresponds to the dimensions of the openings 4 on the bottom shelf 3 of the first section, while the location and size of the lateral projections 11 correspond to the dimensions of the openings 6 on the bottom shelf 5 of the second section. This design allows the side panels to be mated with the bottom shelves of the first and second sections of the cabinet.

[0022] Next, the horizontal lower shelf 5 of the second section is installed on the sides of the lower section. The lower shelf has four holes 6 on the plane, along the edges of its perimeter. The location and dimensions of the holes correspond to the dimensions of the side projections 11 of the inner panel of the locking element. During installation, the side projections 11 of the inner panel of the locking element grip its central projection 10, thereby ensuring the connection of the side panel with the lower shelf 5 of the second section. This forms the second section of the cabinet.

[0023] In each side panel of each section, the middle panel 8 defines the distance between the horizontal shelves, and the outer panel forms the outer side of each section's side panel. To ensure stability, after assembling the two sections, the side panels are secured with spring locks (suitcase locks) or furniture hardware fasteners. In a two-section shelf, as the cabinet is designed for, or in a potential cabinet with multiple sections, the top shelf of each section is provided with a lid 13, significantly expanding the functionality and ease of use of the open cabinet assembly.

[0024] This modular cabinet offers advantages over prefabricated cabinets. Specifically, it's easy to assemble and disassemble, requiring no special skills or tools, making it accessible to everyone. The cabinet can be quickly and easily disassembled, and its panels can be stacked to create a compact package. The cabinet is multifunctional, as it can be used as an open cabinet, a table, a workbench, or a shelving unit for temporary or long-term storage. Its universal nature means it can be used in various spaces, and its casters allow for quick transportation.
