  TECHNICAL FIELD The present invention relates to a lightweight clay molding apparatus used when molding lightweight clay used for rehabilitation teaching materials such as arts and crafts, school teaching materials or nursing homes.

Clay used in conventional arts and crafts and school teaching materials, such as paper clay and oil clay, is used as clay for arts and crafts or teaching materials. Not only many, but also the molding work was difficult. Therefore, at present, in order to solve these problems, extremely lightweight clay has been proposed and sold (see Patent Document 1). The clay disclosed in Patent Document 1 (hereinafter referred to as a lightweight clay) is mainly composed of a light-weight fine material that encloses gas in particles, and has a specific gravity as compared with conventional paper clay and oil clay. The burden during transportation and molding is greatly eliminated.
Japanese Utility Model Publication No. 6-70734

  By the way, there are various methods for making clay used as arts and crafts, school materials, etc., and it is only possible to form from clay clay into the shape of animals such as dogs and cats and fruits such as apples and strawberries. Without forming the clay into a thin plate or sheet, and drying it, a plate-like molded product is formed. By cutting the clay into a desired shape with a cutter or scissors, for example, parts that become plant leaves In some cases, it is molded into flowers and trees by pasting them in large numbers.

  However, with a conventional lightweight clay molding apparatus, it is difficult to easily mold a lightweight clay so as to obtain a desired thickness, and it is also difficult to take out the molded lightweight clay.

  Therefore, the present invention has been proposed in order to solve the above-described problems of the conventional lightweight clay, and can easily form a molded product having an arbitrary thickness. An object of the present invention is to provide a novel lightweight clay molding apparatus that can be easily removed.

  The present invention has been proposed to achieve the above object, and the first invention (the invention according to claim 1) is used as a rehabilitation teaching material for arts and crafts, for school teaching materials or for nursing homes. A lightweight clay molding apparatus used when molding a lightweight clay, wherein a concave portion is formed at the center of the upper surface, and one screw is threaded on the inner peripheral surface at the center of the concave portion. The device main body in which the insertion hole is formed, the elevating plate located inside the recess of the device main body, and the lower surface of the elevating plate are attached, and the outer peripheral surface is threaded on the inner peripheral surface of the insertion hole. A lifting adjustment rod formed by screwing the other screw to be screwed into the other screw, and the operator can rotate the lifting adjustment rod while holding the lifting adjustment rod so that the fixing position of the lifting plate is The upper surface of the elevating plate is immersed below the upper surface of the apparatus main body. From those characterized by comprising been adjustable in the range up to a position projecting above the upper surface of the apparatus main body.

  The elevating plate constituting the first aspect of the invention can be adjusted in the fixing position within a range from a position where the upper surface is recessed below the upper surface of the apparatus main body to a position where the upper surface protrudes above the upper surface of the apparatus main body. Needless to say, it can be set and fixed so that the upper surface of the elevating plate is flush with the upper surface of the apparatus main body. Further, the upper surface of the elevating plate has, for example, a textured fine unevenness so as to prevent the lightweight clay from adhering when removing the lightweight clay, or to form a pattern of the formed lightweight clay. It may be formed. The depth of the recess formed in the apparatus main body may be an appropriate depth depending on the thickness of the lifting plate and the range of the thickness of the plate-like or sheet-like molded product to be molded. The deeper the is, the thicker it can be molded. Further, the shape of the recess is not particularly limited, and may be any shape such as a circular shape, an elliptical shape, or a polygonal shape. To briefly explain the process of molding lightweight clay by using this lightweight clay molding device, first, the fixing position is adjusted so that the upper surface of the lifting plate is flush with the upper surface of the device body, In this state, a commercially available lightweight clay is kneaded (kneading step). And when the said kneading | mixing process is complete | finished, the fixing position is then changed so that the said raising / lowering board may immerse in the recessed part formed in the apparatus main body. Since the difference between the upper surface of the lifting plate and the upper surface of the apparatus main body is the thickness of the molded product, the distance between the upper surface of the apparatus main body and the upper surface of the lifting plate should be increased when forming thick. Conversely, when forming into a sheet shape (thin), adjustment is made so that the upper surface of the lifting plate is slightly lower than the upper surface of the apparatus main body. Then, when the adjustment of the fixing position of the lifting plate is completed, the kneaded lightweight clay is filled in the recess, and the upper surface of the filled lightweight clay is formed so as to be flush with the upper surface of the apparatus body ( Molding process). In such a molding process, it is preferable to use, for example, the outer peripheral surface of a cylindrical body or the tip of a spatula. When the molding process is completed, the upper surface of the lifting plate is adjusted so as to protrude upward from the upper surface of the apparatus main body, and the molded product positioned on the lifting plate is removed and dried (drying process). In addition, the molded product thus dried can be used as a work to be produced without being cut as it is, and can also be cut into a desired shape with a scissors, a cutter, a knife, etc., and further curved. It can be transformed into a three-dimensional shape and used as a part of the work to be produced.

  According to a second invention (invention of claim 2), in the first invention, an opening having a diameter substantially the same as the upper surface of the elevating plate is formed inside the recess of the apparatus main body. In addition, a frame-like body having an upper surface flush with the upper surface of the apparatus main body is detachably disposed, and the upper surface of the lifting plate has an area substantially the same as the area of the lifting plate. A lightweight clay mounting plate having a thickness that is lower than the upper surface of the apparatus main body when the elevating plate is lowered most is placed, and one magnet is mounted on the apparatus main body. The frame-shaped body is provided with the other magnet, and the frame-shaped body is detachably fixed to the apparatus main body by the magnetic attachment of the one and the other magnets. .

  The second invention is obtained by adding a frame-like body to the first invention. The frame-like body is detachably disposed in the recess of the apparatus main body, and an opening is formed inside. In addition, the upper surface is flush with the upper surface of the apparatus main body. The shape of the opening formed inside the frame-like body may be similar to the shape of the recess formed in the apparatus main body, or may be a different shape. That is, when the shape of the opening formed in the frame-like body is similar to the shape of the recess, the molded product formed with the frame-like body removed is attached and molded. If the shape is similar to the formed product and the shape of the opening is different, a molded product having a shape corresponding to the shape is formed.

  According to the lightweight clay molding apparatus according to the first invention (invention of claim 1), a molded article having an arbitrary thickness can be easily formed by adjusting the fixing position of the elevating plate. Thus, the molded product can be easily removed.

  In the second invention (the invention described in claim 2), the upper surface of the elevating plate has a thickness such that the upper surface is positioned below the upper surface of the apparatus body when the elevating plate is lowered most. Since the lightweight clay placing plate is placed, the molded product can be easily removed from the lifting plate together with the lightweight clay placing plate. Therefore, according to the second aspect of the present invention, it is possible to effectively prevent the danger that the elevating plate and the molded lightweight clay adhere and the shape of the molded product is deformed. Also, it is detachably disposed in the recess of the apparatus main body, an opening is formed on the inner side, and a frame-like body whose upper surface is flush with the upper surface of the apparatus main body is a component. Therefore, the lightweight clay can be formed into different sizes or shapes by removing the frame-like body from the concave portion of the apparatus main body.

  Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the drawings.

  First, the lightweight clay will be described in detail, then the lightweight clay molding device will be described in detail, and then the lightweight clay molding method will be described in detail using this lightweight clay molding device. To do.

  This lightweight clay is a commercially available lightweight clay (trademark “Chokaru Paper Nendo”, which is sold by DMC Japan Co., Ltd.), which is mainly made of lightweight micro-material particles. Is made of a vinylidene chloride-acrylonitrile copolymer resin, and gas is encapsulated inside. The light-weight fine material particles are extremely light-weight hollow spheres having a particle diameter of 1 to 200 microns and a bulk specific gravity of 0.01 to 0.05. In addition, 3-20 parts (parts by weight) of lightweight fine material powder, 10-3 parts of fiber powder as an additive, and 10-20 parts of carboxymethyl cellulose, which is a synthetic binder, are added to this lightweight clay. In addition, fibers, synthetic adhesives, preservatives, fungicides, and water as a conditioned liquid material are added. Furthermore, the honey which comprises this invention is added to this lightweight clay. The honey is 0.05 parts by weight added to the lightweight clay. In this example, 0.1 parts by weight of watercolor paint is further added. Further, instead of the honey, a liquid having an alcohol content of 22 to 25 degrees may be added. As such a liquid, for example, alcoholic beverages such as shochu, sake, and cooking liquor can be used.

  Next, a light clay forming apparatus (hereinafter referred to as a molding apparatus) will be described in detail. As shown in FIG. 1, the molding apparatus 1 includes an apparatus main body 2, an elevating plate 3, and a placing plate 4 placed on the elevating plate 3. The apparatus main body 2 is formed with a cylindrical outer shape, and its upper surface is horizontally formed. In addition, a circular first concave portion 2a is formed at the center of the apparatus main body 2, and a second concave portion 2b that is further depressed downward is formed at the center of the first concave portion 2a. Is formed. A circular insertion hole 2c is formed in the center of the apparatus body 2, and one screw (reference numeral is omitted) is threaded on the inner peripheral surface of the insertion hole 2c. One magnet 5 is fixed to a ring-shaped plane (reference numerals are omitted) forming the first recess 2a, and a rubber plate 6 is provided on the lower surface of the apparatus main body 2. It is affixed.

  The lifting plate 3 has a top surface formed in a circular shape, and is formed in the same shape as the second recess 2b. That is, the elevating plate 3 has an area on the upper surface that is substantially the same as the area of the recess 2 b of the apparatus main body 2, and the apparatus main body 2 from a position where the upper surface sinks below the upper surface of the apparatus main body 2. The fixed position can be adjusted within a range up to a position projecting upward from the upper surface. Therefore, in the molding apparatus 1, as will be described later, when the elevating plate 3 is lowered most, the upper surface of the elevating plate 3 is flush with the ring-shaped plane that forms the first recess 2a. It is configured to be. Further, a columnar or cylindrical elevating adjustment rod 7 is fixed to the lower surface of the elevating plate 3, and an outer peripheral surface of the elevating adjustment rod 7 is screwed into an insertion hole 2 c formed in the apparatus main body 2. The other screw 7a that is screwed into the one screw is engraved. A cap 8 that is held by an operator when the elevating adjustment rod 7 is rotated is fixed to the lower end of the elevating adjustment rod 7.

  Further, in the molding apparatus 1 according to the embodiment of the present invention, a ring-shaped frame body 9 is arranged in the first recess 2a. The frame-like body 9 has the same outer diameter as the first recess 2a, has the same height as the depth of the first recess 2a, and has a circular opening 9a at the center. Is formed. The diameter of the circular opening 9a is substantially the same as the diameter of the upper surface of the elevating plate 3. Therefore, the length from the outer peripheral surface to the inner peripheral surface of the frame-like body 9 is the first recess 2a. The length from the inner peripheral surface to the outer peripheral surface of the lift plate 3 is the same. Further, the other magnet 10 that is magnetically attached to the one magnet 5 is embedded in the lower surface of the frame body 9.

  Further, the mounting plate 4 is integrally formed in a disc shape with resin, and the diameter thereof is substantially the same as the diameter of the lifting plate 3. Further, the thickness of the mounting plate 4 is shorter than the depth of the first recess 2a. In addition, on the upper surface of the mounting plate 4 described above, a large number of fine irregularities are formed in a satin shape. Further, in the embodiment of the present invention, although not shown, it is another mounting plate that has the same diameter as that of the first recess 2a, separately from the mounting plate 4. The disk-shaped mounting plate used selectively with the mounting plate 4 is also a constituent element.

  Hereinafter, while explaining the method of using the molding apparatus 1, the above-described lightweight clay molding method will be described. First, while gripping the lifting / lowering adjusting rod 7 or the cap 8, it is rotated clockwise or counterclockwise, and the mounting plate 4 placed on the upper surface of the lifting plate 3 as shown in FIG. Is set to be flush with the upper surface of the apparatus main body 2. When such setting is completed, the above-mentioned honey or liquid having the above conditions is then added to the above-described commercially available lightweight clay, and the upper surface of the mounting plate 4 and the upper surface of the apparatus body 2 are combined so that they are integrated. Evenly kneading using the kneading process (kneading step). Then, when this kneading step is completed, while holding the lifting adjustment rod 7 or the cap 8 again, the kneading step is rotated counterclockwise or clockwise, as shown in FIG. It sets so that the upper surface of the board 4 may be located below the upper surface of the apparatus main body 2. In addition, since how to set the height of the mounting plate 4 depends on the thickness of the molded product to be molded, when the thin sheet-shaped molded product is molded, the mounting plate 4 Is set to be slightly lower than the upper surface of the apparatus main body 2, and when a thick molded product is to be formed, the elevating plate 3 is lowered downward.

  Then, when such setting work is completed, the kneaded lightweight clay is then filled into the depression formed on the mounting plate 4, and as shown in FIG. The smoothness is leveled so as to be flush with the upper surface of the apparatus main body 2, and the lightweight clay kneaded in the depression is formed into a plate shape or a sheet shape by such operations (forming step). In this operation, using a non-illustrated plastic or stainless steel smooth rod formed in a cylindrical or columnar shape or a spatula (not shown) whose tip is horizontal, from one of the recesses. By making the other side slidably contact the upper surface of the apparatus main body 2, leveling can be performed very easily.

  Then, when the above-described forming process is completed, the gripping and lowering adjustment rod 7 or the cap 8 is gripped, and then the clockwise or counterclockwise rotating operation is performed. As shown in FIG. The mounting plate 4 placed on the upper surface and the molded product W are raised above the upper surface of the apparatus main body 2, and the mounting plate 4 and the molded product W are put together on the lifting plate 3 together. And the molded product W is dried (drying step). In the above-described example, since many fine irregularities are formed on the upper surface of the mounting plate 4, fine irregularities corresponding to these irregularities appear as a pattern on the molded product. And when this molded product W is dried, it is removed from above the mounting plate 4 and cut into a desired shape such as a leaf of a plant, using, for example, an unillustrated scissors, cutter, knife, etc. It is used as a part of a not-shown model to be created. If necessary, an arbitrary paint is applied to the surface of each part.

  In addition, when it is desired to form a molded product having a longer diameter than the molded product formed by the above-described method and process, the molded body is fixed to the apparatus main body 2 by magnetic adhesion between the one magnet 5 and the other magnet 10. The frame-like body 9 is removed, and a placing plate (not shown) different from the placing plate 4 is placed on the elevating plate 3, and a molded product having a long diameter is formed by the same procedure as described above.

  According to the lightweight clay molding method described above, not only can it be very easily molded, but even if the molded product W or a part obtained by cutting the molded product W into a desired shape is curved, There will be no cracks or cracks, and it will not be necessary to repair these cracks or cracks, and even if an external force is applied to the finished work by these methods, it will not be easily damaged. In particular, according to the molding apparatus 1 described above, the lifting and lowering plate 3 can be used in the kneading process and the molding process of the lightweight clay by the lifting and lowering operation, and it is extremely simple when removing the molded product W. It will be a thing. Furthermore, since the mounting plate 4 is mounted on the lifting plate 3 and the molded product W can be moved together with the mounting plate 4, the molded product W is removed when the molded product W is removed from the molding apparatus 1. It is also possible to effectively prevent the risk of the inadvertent deformation. Further, in the molding apparatus 1 according to the embodiment of the present invention, since the frame-like body 9 is used as a constituent element, it becomes possible to mold a molded product having two sizes.

  In the description of the embodiment of the invention, the frame body 9 is a component of the molding apparatus 1, and a mounting plate having a long diameter (not shown) that is separate from the mounting plate 4 is also a component. These frame-like body 9 and the mounting plate having a long diameter are not necessarily required as components, and a concave portion (not shown) having the same inner diameter as that of the mounting plate 4 is formed on the upper surface of the apparatus body 2. May be. Further, the mounting plate 4 is not necessarily required as a component of the molding apparatus 1.

  Further, in the case where the mounting plate is used as a constituent element, as described above, the material may be cork instead of resin. That is, the mounting plate 12 made of cork is formed into a thin plate shape and is formed to have a diameter slightly shorter than the diameter of the elevating plate 3 as shown in FIG. Thus, a large number of slits 12a are formed in the center direction from the outer peripheral side. These slits 12a are arranged in parallel at equal intervals in the circumferential direction of the mounting plate 12, and the lengths thereof are the same.

  When the mounting plate 12 having such a configuration is used as a constituent element, the mounting plate 12 is mounted at the center of the elevating plate 3, and a lightweight clay is formed in the same manner as described above, the mounting is a cork. The outer periphery of the mounting plate 12 is surrounded by a lightweight clay, and the numerous slits 12a are filled with the lightweight clay. Therefore, by using the above-mentioned mounting plate 12 made of such cork as a component, the molded product is integrated with the mounting plate 12 and can be used as a part of a work to be created as it is. The mounting plate 12 is not exposed on the outer periphery, the appearance is excellent, the strength is excellent, and further, the risk of the lightweight clay peeling off can be avoided. Moreover, when using the molded object W shape | molded in this way, for example as a coaster, you may apply | coat waterproofing agents, such as a varnish, on the surface.
