This solution does not provide the necessary technological clearance and can be installed in the grooves of the boards.

Known technical solution according to the patent for invention No. US 13532145, filing date 06/25/2012, publication number 20130340377, publication date 12/26/2013, publication type A1 IPC E04B 1/38, Hidden Clasp for flooring. A fastener for use in adjacent deck members, comprising: a generally flat body extending from left end to right end between leading and trailing edges, a body defining an opening passing through it; a drive arm projecting upward from a leading edge of the hull, having a drive wing protruding therefrom in a direction away from the hull; in retracting the leg extending upward from the body of the trailing edge, having at least one hind leg extension of them in the direction away from the body, the hind leg defining the notch indented towards the body, mainly in registry with the body opening, notch splitting the hind leg on the right and left sides; and at least one protrusion extending downward from the trailing edge of the body. This technical solution does not ensure the durability and reliability of the structure, does not prevent warping of the boards. In addition, the installation of this technical tool is laborious.

The closest technical solution is a patent for an invention, International Application No. PCT/US2015/036747, International filing date 06/19/2015, Publication number WO/2015/196108 Publication date 12/23/2015 IPC F16B 2/20 (2006.1), F16B 2/24 ( 2006.1), F16B 15/00 (2006.1), DECK CLAMP, A clamp for fastening a deck board to a structure, comprising a clip: a hull part having a front side and a back side, the back side is configured to rest on the side surface of the deck board; at least one horizontal portion extending outward from the front side of the hull portion to the distal end and configured to fit into a groove of an adjacent deck board, the distal end including a rounded portion; and a hole in the hull part for receiving fasteners, a hole configured to pass fasteners through the hull part and into the deck board, and the beam. This technical solution does not ensure the durability and reliability of the structure, does not prevent warping of the boards.

Warping of the board depends not only on the quality of its processing in the drying chamber, but also to a large extent on the properties of the wood itself: its density, the presence of natural defects such as knots and frizz, and texture diversity. Warping of the board is provoked by internal stresses that occur when the wood is unevenly dried or moistened.

Due to warping, the edge of the board may bend and the self-tapping screws can be pulled out of the log. In both cases, the coating requires repair with partial replacement of the boards.

Technical task: Hidden grooved fasteners for mounting terrace and facade boards are necessary to counteract warping of the terrace and / or facade board, which has side longitudinal grooves, during their operation.

Thus, the claimed technical solution achieves the following technical result:

increases the reliability of fastening the connection of the terrace board with the log and the durability of the mounted coating;

provides simplicity and ease of installation of fasteners.

This technical result is achieved as follows.

Hidden grooved fasteners for mounting terrace and facade boards, characterized by location in the grooves of the board, is a rectangular base, characterized in that the rectangular base contains a horizontal part extending across the entire width of the fastener plane; two folding rectangular support tabs in the side planes of the fastener, directed towards the log and acting as a spacer, and the width of the support tabs is equal to the width of the technological gap between the mounted boards; a folding fixing shelf in the front plane of the fastener, to keep the fastener from falling out of the board groove during installation, bent from the base plane at an angle of 20-70 °, to ensure the screw is screwed into the log at an angle and directed in the opposite direction from the log, containing a hole for the fastener element to connect with the lag.

In this case, the hole for the fastener is made round and/or oval. The horizontal part contains additional stiffening ribs. The rectangular base contains one folding rectangular support tab in the side planes of the fastener.

This technical solution is illustrated by the following drawings.

Fig. 1 General view of fasteners.

Fig. 2. Installation of fasteners in the groove of the board.

Fig. 3. Fixing the fastener with a self-tapping screw or a nail through the hole into the folding fixing shelf of the fastener in the groove of the board and installing the next board.

Fig. 4. The location of the fasteners in the groove of the board.

The proposed technical solution is implemented as follows.

Hidden slot fasteners for mounting terrace and facade boards "KRYLAN" are made in the form of a flat rectangular blank of plastic or metal, including stainless steel, aluminum or its alloys. Further, one or two rectangular support tabs (1) in the side planes of the fastener and a fixing shelf (2) in the front plane of the fastener are bent from the fastener plane to keep the fastener from falling out of the groove (3) of the board during installation. In this case, the fixing shelf (2) is bent from the base plane at an angle of 20-70°.

Hidden groove fasteners for mounting terrace and facade boards are placed in the grooves (3) of the board in such a way that the horizontal part (4) protrudes beyond the groove (3) of the board, and the rectangular support tabs (1) abut against the end of the board (5) and are directed towards the log (6). During further installation, the horizontal part (4) of the fastener is inserted into the groove of the next board. In this case, the support legs (1) play the role of a spacer, due to which they ensure the formation of a technological gap between the boards, and the width of the support legs is equal to the width of the gap between the boards during their installation.

The folding fixing shelf (2) in the front plane of the fastener is placed in the groove (3) of the board in such a way that the upper part of the fixing shelf (2) abuts against the upper plane of the groove (3) of the board, due to which the fastener is kept from falling out, this ensures simplicity and ease of installation of fasteners, since it does not require additional holding of the fastener at the place of fixation and facilitates the possibility of installing the fastener (7) in the hole (8) for the fastener to connect to the log. At the same time, due to the fact that the fixing shelf (2) is bent from the base plane at an angle of 20-70°, the fastener (7) is screwed into the log (6) at an angle, which prevents further warping of the terrace and / or facade board, which has lateral longitudinal grooves during operation, and also increases the reliability of fastening the connection of the terrace board with the log in comparison with analogues.

When using the proposed invisible fasteners, the following technological operations are performed.

Fasteners are installed in the groove (3) of the board and fixed to the log (6) with a fastener (7) through a hole (8) located in the hinged fixing shelf (2). The subsequent board is installed in such a way that the horizontal part (4) of the fastener enters the groove of the subsequent board, while the distance between the mounted boards will be equal to the width of the technological gap, which provides a distance equal to the width of the supporting legs (1).

In this case, the hole (8) for the fastener (7) can be made round or oval for any type of fastener, such as a self-tapping screw or a nail. The horizontal part (4) may contain additional stiffening ribs, which will ensure the reliability of the horizontal part in bending. In this case, the fastener may contain one folding rectangular support tab (1) in the side planes of the fastener, which will also provide the necessary technological clearance.

In this case, the horizontal part (4) can be not only rectangular, but also of a different shape, including square, oval, trapezoidal, which provides clamping of adjacent boards through the groove and twisting the self-tapping screw at an angle in the log.

Standard sizes do not exhaust all possible options for hidden groove fasteners for mounting terrace and facade boards.

Thus, the proposed technical solution ensures the rigidity of the structure due to the high reliability of the connection of the parts of the structure, a significant improvement in the performance of the wooden structure, associated with a decrease in the warping of the boards.
