AI Technical Summary
Thin wooden plates are prone to warping during drying and traditional methods of fixing them with nails or adhesive materials fail to provide sufficient strength, leading to unusable warped surfaces, especially when creating wide surfaces.
The wooden plates are cut on the back with small mouths and fitted with members to connect at these points, minimizing the joint surface and reducing warpage by distributing the force evenly.
This method effectively prevents warping by ensuring strong connections at specific points, allowing for the creation of wide surfaces without expensive coatings or additional processing.

Abstract
Description
[Technical field]
[0001] This product is for creating thin wooden boards with a wide surface area. About the best technology to prevent board warping
[0002] When joining wooden boards together to make a wider board, make cuts in the edges. Insert the fixing member in that part and connect the plate only to the fixing member. This is a technique that does not join the boards at other points. Summary of the Invention [Problem to be solved by the invention]
[0003] When using thin (6 mm, etc.) wide boards, the boards will inevitably dry out. To prevent the boards from warping, we put in some metal fittings and boards to prevent the boards from warping. The board itself is thin, so it cannot be firmly fixed with nails, etc. The warping force of the board is quite strong, and it is particularly difficult to make a board with a wide grain. Yes, it is expensive to apply coatings or other processes to dry a single board and prevent it from warping. Otherwise it would have been impossible
[0004] The purpose of this product is to provide a product that is extremely resistant to warping without the need for expensive coatings or processing. This is a processing method to create fewer boards. [Means for solving the problem]
[0005] The board used for this product has a notch on the back and a notch on the edge. By inserting parts at the ends to connect the boards together, the boards are prevented from warping. Effect of the Invention
[0006] When making a wide, thin wooden board (6 mm, etc.) using conventional methods, Whether a single board is used or boards are simply lined up and glued together, the board will warp strongly. It can also be used as a cover for products, A sliding lid that can be pulled out from the box It was difficult to burn the boards to make them black (they dry out when burned, The adhesive will melt and peel off.) Even if you try to attach a material to the back of the board to prevent warping, the grain of the board will still be prone to warping. It is quite strong and the adhesive will cause the warp to be too strong, so it is not strong enough to use nails. Not usable because the plate is not thick enough
[0007] This product has a notch on the back of the wooden board to prevent warping. By making a cut in the edge of the wood and inserting a piece of wood into it, warping is prevented. The plates are only connected at the component parts, and the joint surfaces between the plates are as close as possible. By reducing the amount of material, the individual warping forces are dispersed. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0009] Make a cut on the back of each piece of wood that will be connected. Make a cut on the edge of the piece of wood Insert the board parts into the slits on the edge to connect the boards together.
Claims
[Claim 1] For connecting thin wooden boards (6 mm etc.) Limited to the parts inserted in the cut on the end face To create a large area of board without joining other parts
