Description

The tongue-and-groove construction of O. Simashov belongs to the manual cutting tools used in the carpentry (B 27 G 17/02, B 27 F 1/02).

State of the art

The closest analogue of the declared tongue and groove is a tool for cutting the crest and groove, known from US patent No. 2344897 of 03/21/1944, which contains a figured platform with a longitudinal groove for cutting the crest and groove on the edge of the board, a transverse slot in the platform for outputting wood chips removed a cutter, an inclined guide that serves as a support for the cutter, a pressure plate resting on the axis, used to fasten the cutter, a locking screw for rigidly fixing the cutter and a guide plate that provides tool travel parallel to the edge of the processed board.

SUMMARY OF THE INVENTION

The essence of the invention lies in the fact that: if a longitudinal slot of a given depth and width and a similar slot in a planing knife are made in the sole of a regular plane, this configuration will allow you to cut a tongue and groove on the edge of the board. And if you install an insert of rectangular cross section of the same width as the groove in the groove obtained by milling, then this design will allow you to cut the groove of the tongue on the back of the board with the same plane, relative to the same given plane.

The design of this dowel allows the production of sheet piling boards of the "lining" type (finishing for wall and ceiling upholstery with a thickness of 20-25 mm), as well as floorboards with a thickness of 40-50 mm. Recommended moisture content of the starting material is 3-4%.

The proposed design of the tongue is highly specialized, which increases the quality of the product and its reliability, as well as ease of use.

The purpose of the invention: 1. Expanding the technical capabilities of home workshops and increasing the autonomy of an independent developer. 2. Savings in lumber, which is achieved by reducing (two to three times) the surface required for upholstering used for planing boards.

In machine (automatic four-sided) processing, the thickness of the removed double layer is 5 mm, i.e. a board 25 mm thick after trimming has a thickness already 20 mm. When manually processing the edged board, it is necessary to cut off only one surface, which will later be the front and will serve for the interior upholstery with the subsequent application of a transparent protective and decorative coating (matte varnish finish). The reverse side of the board does not need to be planed out for two reasons: 1) no one sees its appearance; 2) the tongue is able to cut the tongue relative to one side of the board, he does not need a second plane.

For upholstery of the street (external) side of the structure under construction, the board used may not be planed at all, but only have a tongue if; 1) the street side of the wall is sheathed with some decorative material, it can be: siding (or vinyl lining), sheet slate or shingles (laths, netting) followed by plastering; 2) if it is planned to finish the street walls with an opaque protective and decorative coating (for example: colored oil or alkyd paints).

Applying paint to a non-planed surface of the board (especially if the paint is applied manually with a brush) greatly increases the adhesion of the paint to the board, which in turn guarantees the wall surface from possible peeling of the paint (blistering, peeling). And this will increase the duration of a healthy lifestyle of street walls and reduce the cost of their maintenance.

Information confirming the possibility of carrying out the invention.

The tongue and groove consists of: a figured platform 1 having a transverse slot 2 for removing wood chips removed by the cutters shown in Figs. 4 and 5 (Fig. 4 - a cutter for planing a ridge on a board edge, Fig. 5 - a cutter for planing a groove on a rib boards), as well as a longitudinal groove 4, which allows you to plan the comb on the edge of the board; in the same groove 4 is installed using screws 6 insert 5, which allows you to plan a longitudinal groove on the edge of the board, also insert 5 is a support for the cutter of figure 5; the triangular guide 7 is attached to the platform 1 with screws (two on each side, or is a monolithic part of the platform, if the rough blank of the latter is made by casting), which serves as a support for the cutters and the basis for the installation of the adjusting mechanism 8, which carries out the adjustment the release of the cutters shown in figures 4 and 5 (providing adjustment of the thickness of the removed layer); fastening of the cutters is carried out by the pressure plate 9, based on the axis 10; rigid fixation of the cutters is carried out by the locking screw 11; the guide plate 12 provides parallel movement of the tongue relative to the board being machined, and also using the pins 14 and locking screws 13, the cutting ridge or groove is moved (left-right and left) on the plane of the edge of the board, i.e. centering the cut sheet pile relative to the midline of the edge of the board; the rear handle 15 is attached to the platform 1 with a screw 16; the front handle 17 is attached to the platform 1 with a screw 18.

The method of cutting the dowel on the board.

1. Select the required thickness of the board.

2. Depending on the thickness of the board, select the dowel of the required width.

3. Install the worktable on the desktop.

4. Set the working plane (cut off with a regular plane one of the sides of the board, provided that this side is the front).

5. To cut off the edges of the board with a regular planer (if required).

6. Depending on the location of the board, determine which side of the board will run the comb and which groove will be on.

7. Install one of the cutters in the tongue, set its release with the adjusting mechanism 8 and tighten with the locking screw 11.

8. Using the guide plate 12 and pins 14, center the tongue relative to the center of the edge of the board and fix the installed position with screws 13.

9. Proceed to cutting the tongue (crest or groove).

10. Without changing the position of the guide plate 12, change the cutter (and also remove or install the insert) and adjust its output.

11. Turn the board to be processed on the other side, face to you.

12. Cut the counterpart of the tongue and groove.
