Description

[Detailed explanation of the idea] If you cut a tree into rings and dry it, cracks will appear.Cracks will also appear if the tree is cut into planks or straight grains like wood for construction. This is just a crack, whereas the crack in the round plate is about 16 centimeters in diameter, and a triangular shape of 3 centimeters or more is formed at the periphery from the center.

Traditional round cutting tables are made by cutting the roots of trees diagonally. Tree roots have a complicated grain pattern, so cutting diagonally can prevent them from splitting. It takes time to dig out the roots, and the roots are covered with stones, so removing them is a difficult task. The round plates made in this way end up being expensive.

When a round board is dried, it cracks. What happens if you let it absorb more water than normal? If you soak a round board in water, heat it, and make it absorb water, the round board will pass through the heart and the surrounding area. Cracks appear towards the parts, and the cracks are wider near the heart.When the sliced board is dried, the cracks return to their original state and become invisible, and then they are dried further. Then, the cracks appear in the same way as a regular round board.

In this invention, as shown in Figure 1, if the cutting board 1 is about 16 centimeters in diameter and the cut 3 is made through the core 2 of the cutting board 1 which is made by cutting a tree into rings, then the cut 3 is about 4 centimeters long in the heartwood part. Insert.

The cuts 3 are made so that they are wide near the core 2 and narrow at both ends.This is because when the round plate 1 is dried, it shrinks more near the core 2.

As mentioned above, even when the round plate 1 with the cut 3 is dried, there will be no cracks, and the cut 3
By widening the area near the core 2, the part where the slit 3 is inserted will look like nothing more than a crack.If the slit 3 is made the same width, even when the slit 2 is in contact with the slit 3, the slit 3 near the periphery will be Cuts 3 remain, and when the cuts 3 near the periphery touch, the cracks grow.

For trees that are particularly susceptible to breakage or deformed trees, making two cuts 3 as shown in Figure 2 will eliminate the need for small cracks.

When the round plate 1 is soaked in water and heated, it will crack in areas where cracks are likely to enter, so it is best to make cuts 3 in those cracked areas.

When making cuts 3, it is best to make the cuts 3 on the back side of the round cutting board 1 wider than the cuts 3 on the front side when used as a round cutting table.
The trick is to make the cut 3 on the surface of the round plate 1 stick together without creating any cracks.
becomes invisible.

The width of the cut 3 is about 2 mm near the periphery and about 7 mm near the center 2, which is the standard width for the cut plate 1 having a diameter of about 16 cm.

Claims (1)

[Scope of utility model registration request] As shown in Figure 1, by making cuts 3 in the core of the round plate 1 toward the periphery, you can prevent cracks from forming even when drying, and make the cuts 3 near the core 2 wider. By doing this, the cut 3 is narrowed to the extent of a crack.
