Abstract

This utility model relates to the renovation and construction industry, specifically to skirting boards designed to create a floor-to-wall junction and serve as a guide when installing sheet material, such as drywall, to a building's main wall. The technical result improves the reliability of fastening the bottom end of the drywall sheet while fully preserving its backlighting function and durability. This technical result is achieved by a skirting board comprising a vertical support in the form of a plate with ribs on the inner side and a first diffuser fastening element located on the outer side of the support. The upper end of the vertical support is connected to the inner end of a horizontal shelf. The central portion of a short vertical shelf is attached to the outer end of the horizontal shelf, with a second diffuser fastening element located on the lower portion of the shelf (opposite the first diffuser element). The width of the horizontal shelf is 12-13 mm.There may be continuous outer ribbing (corrugation) of the short vertical shelf, corrugations on the upper surface of the horizontal shelf, a triangular protrusion at the bottom of the outer surface of the short vertical shelf, a C-shaped connecting element in the corner between the upper surface of the horizontal shelf and the upper part of the short vertical shelf.

Description

[0001] The utility model relates to the repair and construction industry, namely to skirting boards designed to decorate the junction of the floor and the wall, used as a guide when installing sheet material, such as drywall, to the main wall of a room.

[0002] The closest to a utility model is "Built-in skirting board with a shadow gap" WO 2023277732 [1], which contains a vertical support, coupled (connected) to a horizontal shelf, at the end of which is a vertical shelf directed downward from the horizontal shelf to form an open downward cavity under the horizontal shelf for an LED strip. Mounting elements for a diffuser are located on the support and the vertical shelf.

[0003] The disadvantage of the known solution is the low efficiency of the backlight, caused by the offset from the center of the cavity under the lower end of the gypsum board.

[0004] The technical result is an increase in the reliability of fastening the lower end of the gypsum board sheet while fully maintaining the backlight function and durability.

[0005] The technical result is achieved in that the plinth, containing a vertical support in the form of a plate with ribs on the inner side and with a first element for fastening the diffuser, located on the outer side of the support, the upper end of the vertical support is connected to the inner end of the horizontal shelf, is characterized in that the central part of the short vertical shelf is attached to the outer end of the horizontal shelf, on the lower part of which the second element for fastening the diffuser is located (opposite the first element of the diffuser), and the width of the horizontal shelf is 12-13 mm.

[0006] Implementation of a utility model

[0007] The figure shows a profile where

[0008] 1 - vertical support;

[0009] 2 - the first element of the diffuser fastening;

[0010] 3 - horizontal shelf;

[0011] 4 - short vertical shelf;

[0012] 5 - open cavity for LED strip;

[0013] 6 - the second element of the diffuser fastening;

[0014] 7 - side;

[0015] 8 - riffles on a vertical shelf;

[0016] 9 - riffles on a horizontal shelf;

[0017] 10 - triangular protrusion;

[0018] 11 - C-shaped connecting element;

[0019] 12 - riffles on a vertical support.

[0020] The device operates as follows:

[0021] A horizontal shelf 3 is fixed to the vertical support 1 with the first fastening element of the diffuser 2, to the end of which, opposite from the vertical support, a short (compared to the height of the support) vertical shelf 4 is fixed, partially directed downwards from the horizontal shelf, with the second fastening element of the diffuser 6. The vertical support together with the horizontal shelf and with the short vertical shelf partially directed downwards form an open cavity for the LED strip 5. The upper part of the short vertical shelf (above the abutment point of the horizontal shelf) forms a side 7. On the short vertical shelf there are corrugations 8, in the lower part of the short vertical shelf there is a triangular protrusion 10. On the upper side of the horizontal shelf there are corrugations 9. On the inner side of the profile, in the corner between the upper surface of the horizontal shelf and the upper part of the short vertical shelf there is a C-shaped connecting element 11.On the vertical support, the inner surface (facing the main wall during installation), there are riffles 12.

[0022] The influence of the features of the formula of the utility model of the baseboard on the technical result:

[0023] Vertical support plate with grooves on the inside. The grooves increase adhesion to the supporting wall and prevent profile shifting during installation, ensuring a stable base for the entire structure.

[0024] The first diffuser fastening element on the outside of the support ensures reliable fixation of the diffuser on the wall side, guaranteeing uniform light distribution and protection of the LED strip.

[0025] Horizontal shelf, 12-13 mm wide. Critically important dimension: provides sufficient rigidity to support the bottom end of a standard 12.5 mm thick drywall, ensuring secure fixation of the bottom end of the drywall adjacent to the wall.

[0026] A short vertical shelf, connected by its central part to the outer end of a horizontal shelf, provides the upper part for securing the lower end of the plasterboard, and the lower part for hiding the direct radiation of the backlight to achieve the necessary diffused lighting in the corner of the room.

[0027] The second diffuser fastening element on the bottom of the short vertical shelf (opposite the first) forms a diffuser fixing system that prevents its displacement and ensures stable geometry of the light flux.

[0028] Additional features (dependent claims).

[0029] The continuous outer ribbing (corrugation) of the short vertical shelf (item 2) allows you to apply putty, hiding part of the baseboard in the area of ​​​​the transition from the lower to the central part of the gypsum board, and increase the reliability of fastening the lower part of the gypsum board.

[0030] The grooves on the upper surface of the horizontal shelf (item 3) increase the coefficient of friction with the lower end of the gypsum board, reducing the risk of slipping and increasing the reliability of the sheet fixation.

[0031] The triangular protrusion at the bottom of the outer surface of the short vertical shelf (item 4) serves as a beacon (guide) for filling the bottom of the gypsum board.

[0032] The C-shaped connecting element in the corner between the top surface of the horizontal shelf and the top of the short vertical shelf (item 5) provides a tight and rigid connection of adjacent profiles, increasing the overall stability of the system around the perimeter of the room.

[0033] The overall height of the short vertical shelf is 40-41 mm (item 6). Optimized size for secure fixing of the plasterboard sheet without increasing cutting accuracy requirements, as well as for the placement of a second diffuser mounting element while maintaining backlight efficiency.

[0034] The distance between the lower end of the support and the upper end of the short vertical shelf (the full height of the profile) is 110-115 mm (item 7) ensures reliable fixation of the baseboard to the wall, covers the standard gap between the floor and the wall, accommodates LED lighting and maintains the ergonomics of gypsum board installation.

[0035] The lower part of the short vertical shelf 14-15 mm (item 8) ensures correct fastening of the diffuser, the absence of excessive shading of the light from the LED strip, as well as sufficient heat dissipation from the LED strip, which extends its service life.

[0036] Industrial applicability

[0037] The skirting board can be manufactured industrially on standard equipment for the production of metal profiles used in the construction industry.

[0038] The skirting board can be used in the construction and renovation of residential, public and industrial buildings to decorate the junction of the floor and wall with integrated LED lighting with the installation of plasterboard structures (GKL) as a guide for precise positioning and reliable fixation.
