Description

The present invention relates to an auxiliary tool for producing a plate-shaped ceramic with a grain pattern, and more specifically, when producing a plate-shaped ceramic with a grain pattern, anyone can easily create a plate-shaped ceramic with a grain pattern without requiring skill. It is a technique related to an auxiliary tool that can be suitably used for producing a plate-shaped ceramic with a grain pattern that can be expressed.

Pottery and porcelain are collectively called porcelain as earthen products that are semi-permanently hardened by firing in a kiln, etc. The type and properties can be changed in various ways depending on the firing method and the glaze.

The details of the pottery production method are described in, for example, Patent Document 1 (the name of the invention "ceramic tableware"), but in particular, the patterning applied to the pottery, such as a grain pattern, is described. It is often done in the middle of the production process, and it is said that it is difficult for beginners because it requires advanced skills and knowledge, as well as skill and experience.

On the other hand, in Patent Document 2 (invention name "ceramic product with wood grain pattern and its manufacturing method"), clay prepared in a predetermined composition is developed into a thin plate on a flat substrate and rolled up from a small edge to form a cylindrical body. There is a description that the surface (cut surface) of the grain pattern can be obtained by forming the above and cutting along the diameter of the cylinder.

According to the conventional method including the disclosure techniques of Patent Document 1 and Patent Document 2, the patterning including the grain pattern applied to the ceramic is often performed in the middle of the production process, and in addition to the advanced technique and knowledge, Since skill and experience are also required, there is a problem that it is difficult for beginners, and a method for producing ceramics with a grain pattern that anyone can easily express without skill has been sought.

Moreover, in the production of ceramics with a grain pattern, as shown in FIG. 2 of Patent Document 2, clay is spread on a flat surface, pigment powder is sprayed on the upper surface thereof, and then the cylinder is rolled up from the edge. Since it is formed and cut along the radial direction of the cylinder as shown in FIG. 5 of Patent Document 2, an orderly grain pattern is expressed on the cut surface within the radius of the cylinder. As a result, there was also the inconvenience that it was not possible to produce a preferable grain pattern, although it exceeded the radius of the cylinder.

The present invention was made in view of the above-mentioned problems seen in the prior art, and anyone can easily express the grain pattern on the produced product itself without requiring skill, and the surface size is relatively wide. It is an object of the present invention to provide an auxiliary tool for making a plate-shaped pottery with a grain pattern, which can produce a plate-shaped pottery with a grain pattern.

The present invention has been made to achieve the above object, and is between a long through hole formed between one side end surface and the other side end surface in the straight direction and between the outer surface and the inner surface. Each is provided with a short through hole drilled in a direction orthogonal to the long through hole and an introduction port vertically arranged via a gap having the same width in the length direction of the upper side surface of each. The first to fourth pedestals, which have a pair of separately recessed holding holes and can be arranged adjacent to each other in a square view in a plan view as a whole, and the first to first pedestals arranged adjacent to each other. Four connecting rods that freely horizontally connect the four pedestals to move in the XY directions via the long through hole and the short through hole, and in the Z direction via the holding hole. Eight supporting rods, two of which are arranged upright, and a rectangular plate with a thickness that fits in the void when vertically arranged in a surrounding wall shape on all sides via these upright supporting rods. It is prepared according to the size of the opening surface of the square partition area having the square partition area formed by the side plate and the rectangular side plate that is driven by the movement of the first pedestal body to the fourth pedestal body, and is described above. It is composed of at least a rectangular bottom plate mounted via each partial portion of the first pedestal body to the fourth pedestal body, and has the long through hole, the short through hole, and the pair of holding holes in each. Regarding the positional relationship, when the first pedestal body to the fourth pedestal body are arranged adjacent to each other so as to exhibit a square view in a plan view, the long through hole and the short through hole facing each other communicate with each other. The most important feature is that the lines connecting the center positions of the pair of the holding holes are arranged so as to form a square.

The rectangular side plate and the square bottom plate in the present invention are preferably formed of a material having low water absorption and low hygroscopicity. Further, the rectangular side plate may be provided with a bending preventing rib on a part of one side surface thereof in the length direction.

To.

As shown in FIGS. 1 and 2, the four rectangular side plates 56 having such an arrangement relationship are vertically arranged in a surrounding wall shape through the gap t so as not to interfere with each other, and as a result, four plates are arranged. A rectangular partition area 61 can be formed in the rectangular side plate 56. The rectangular side plate 56 is made of a material having low water absorption and low hygroscopicity so that the natural drying of the clay layer for making ceramics can be delayed and the plate-shaped ceramics having a grain pattern can be molded relatively easily. It is desirable to use it to form, for example, a metal plate having a length of 3 cm, a length of 15 cm and a thickness of 5 mm, which can be stably placed vertically in the void t, or a synthetic resin plate such as a foamed vinyl chloride plate. It can be suitably used. Further, when the rectangular side plate 56 is formed of a synthetic resin plate, as shown in FIG. 11A, in order to reliably prevent outward bending when the clay layer 72 for ceramic production is laminated and arranged.

Those having substantially the same surface size according to the surface size of the rectangular section area 61 are prepared, and as a result, as shown in FIGS. 2 and 3, the first pedestal body 12 to the fourth pedestal body 42 are passed through each partial portion. By placing the clay, the clay accommodating portion 63 as a rectangular space area 62 having an opening surface 62a on the upper surface is secured. It should be noted that the square bottom plate 58, like the rectangular side plate 56, is difficult to delay the natural drying during the production of the clay layer 72 for producing ceramics so that the plate-shaped ceramics having a grain pattern can be molded relatively easily. It is desirable to use a material that absorbs water and moisture, and for example, a material formed of a synthetic resin plate such as a metal plate or a foamed vinyl chloride plate prepared separately for the surface size of the rectangular partition area 61 is preferable. Can be used.

Further, in the present invention, the upright state is more stably maintained for each of the two supporting rods 55, 55 that are separately arranged upright on the first pedestal body 12 to the fourth pedestal body 42. As shown in FIG. 9, it can be inserted and arranged on the upper end portion 55b side via a pair of through holes 59a and 59b provided in the space holding plate 59 for making the gap holding plate 59. In this case, by arranging an elastic material (not shown) such as a rubber ring on the upper end portion 55b of each support rod 55, the spacing plate 59 can be prevented from slipping off after the arrangement. You can also make sure that it can be blocked.

Furthermore, the first pedestal body 12 to the fourth pedestal body 42 in the present invention can be freely fixed to the four connecting rods 54 after being moved in the desired XY directions. It is desirable to provide the position fixing means 52 as described above. In this case, the position fixing means 52 includes a screw hole 52a provided in a positional relationship orthogonal to the long threaded rods 13, 23, 33, 43, and short threaded rods 14, 24, 34, 44, respectively. It is formed by a screw hole 52a provided in an orthogonal positional relationship and a screw rod member 52b screwed and arranged via these screw holes 52a, and the screw rod member 52b is formed on the long through holes 13, 23, 33, 43 side. It is desirable that the position can be fixed by screwing it into the short through holes 14, 24, 34, 44.

Further, in the present invention, in addition to the above components, for example, as shown in FIG. 3, a first clay layer 72a having a different color is formed in the clay accommodating portion 63 secured by the rectangular space area 62. As shown in FIG. 11A, two types of the second clay layer 73b and the clay layer 72 for making ceramics, which are alternately and repeatedly laminated and arranged, are pressure-welded to each upper surface side in order to bleed air from each layer. For example, a roller 71 as shown in FIG. 10 can be provided as an additional member.
