Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a hand board for a pottery wheel used in making ceramics.

[Prior art] Conventionally, when making large ceramics using a pottery wheel, if the work is removed from the wheel while the clay is still soft and transported, the work may be deformed or damaged. Therefore, as a way to prevent this, it is possible to place a tortoiseshell-shaped board on the rotating disk of the potter's wheel and fix it in advance, mold the work on this board, and then carry the work with this board when finished. For this purpose, a hand board for pottery wheels, commonly known as a turtle board, is used.

This type of hand board is generally made by fixing two crosspieces parallel to one side of an octagonal flat plate A, as shown in Figure 5, or by processing the flat plate A into a circle and similar to the above. When placing these on the top of the rotating disk C of a pottery wheel, first wipe the crosspiece well with a cloth dampened with water, and then clean the space between the rotating disk H and the crosspiece. By interposing clay,
Furthermore, a method in which the two are bonded and fixed is widely used.

[Problems to be solved by the invention] As mentioned above, the hand board commonly called a turtle board described in the conventional art has a structure in which two crosspieces are arranged in parallel and fixed to one side of a flat board A. Because of this, when placing it on top of the rotating disk A of a pottery wheel, it is extremely easy and stable to place it on top of the rotating disk C of a pottery wheel. When adhering and fixing the clay between the two discs A, it is necessary to get used to judging the hardness of this soil from experience, and when the flat plate A rotates, it is necessary to use a potter's wheel to prevent rotational wobbling. The problem is that it requires a technique such as aligning the center of the rotating disk C and the center of the flat plate A well and then fixing them horizontally with adhesive.

In addition, as mentioned above, the hand board and the rotating disk of the potter's wheel are glued and fixed with clay interposed between them, so they are twisted into the mass of clay that is kneaded during the molding of the work. If there are layers like this, there will be resistance and the shape will be easily distorted. Furthermore, since a considerable amount of force was required to raise and lower the clay during soil rolling, there was also the problem that the hand plate would shift due to this force and often lose its center.

The present invention was devised in view of the above-mentioned problems of the conventional technology, and its purpose is to make it possible to securely fix the hand board to the rotating disk of the pottery wheel by simple operation, and to To provide a potter's wheel hand board which eliminates problems such as the center of the hand board being shifted when it is fixed to the rotary disk, and which can be easily used by anyone without requiring difficult techniques.

[Means for solving the problem] In order to achieve the above object, the hand board for the pottery wheel in the present invention has four corners on the same surface of the flat board.
A fixing piece for fixing the rotary disc close to the outer edge thereof is provided at the location, and the inner surfaces of the flat plate and the fixing piece are configured to encompass the rotary disc, thereby making it an inset type. It is something.

Preferably, the hand plate has a structure in which a cloth impregnated with water is interposed between the flat plate and the rotating disk, and fixed pieces are fixed to four corners of the flat plate close to the outer edge of the rotating disk.

Further, the shape of the flat plate is preferably octagonal, but there is no particular limitation on the shape as long as it does not hinder rotation, such as a circular shape.

[Function] The hand board for the pottery wheel of the present invention has a structure in which fixed pieces are provided at four corners on the same side of the flat plate, so if this hand board is fitted onto the rotating disk, the inner surface of the flat plate and the fixed pieces will be removed. is in close contact with the rotating disk, and the hand plate rotates to encompass the rotating disk. At this time, if a cloth soaked in water in advance is attached to the rotating disk and interposed between it and the hand plate, it is possible to prevent the hand plate from loosening or rattling.

[Example] Examples will be described with reference to the drawings.

In FIGS. 1 to 4, the flat plate 1 is made of wood, for example, and has a thickness of about 1 to 2 cm, and is a square substrate whose side is approximately the same length as the diameter of the rotating disk 3 of the potter's wheel. Furthermore, the four corners of the substrate are cut to form an octagonal flat plate.
Note that when cutting the four corners of the board, a circle with the same dimensions as the diameter of the rotary disk 3 of the potter's wheel is drawn in the center of the board in advance, and an octagon is cut on the board close to the outer edge of the circle shown. Draw baseline lines at four corners so that

Next, lines are drawn at four locations parallel to the base line at intervals corresponding to the thickness of the substrate, and the four corners of the substrate are cut using the parallel lines as cutting lines to obtain an octagonal flat plate 1.

Further, the fixing pieces 2 are cut pieces obtained by cutting the four corners of the substrate, and by fixing the cut surfaces of the cut pieces to the four corners of the flat plate 1 processed into an octagonal shape, the first The hand board for the pottery wheel of the present invention illustrated in Figures 4 to 4 is completed.

When using the hand board for a pottery wheel of the present invention, as shown in FIG. By configuring the inner surface to include the rotating disk 3, it is inserted and used.

[Effects of the invention] Since the present invention is configured as described above, it produces the following effects.

In the hand board for a pottery wheel according to claim 1, the inner surfaces of the flat plate and the fixed piece are constructed so as to encompass the rotating disk, thereby making it an inset type. This eliminates unnecessary efforts such as aligning the plates well and then fixing them horizontally, making it possible to reliably obtain the center of the plate with a simpler operation.

Furthermore, in hand boards for pottery wheels, water-soaked cloth is interposed between the flat plate and the rotating disk, which increases the degree of adhesion, thereby preventing rotational wobbling when the hand board rotates, and It is possible to completely prevent the hand board from loosening or wobbling.

In the hand board for a pottery wheel according to claim 2, the fixing pieces are fixed at four corners of the flat plate close to the outer edge of the rotating disk, so that when the hand board shifts during molding the work and often loses its center, it can be easily fixed. The above conventional problems can be completely eliminated, and the hand board can be held horizontally and stably.
