  Each acoustic board 110 is a substantially rectangular wooden plate in plan view having the same short direction (width), and when arranged in a long order, the length in the longitudinal direction is gradually shortened (that is, they are long to each other). Are different). Each acoustic board 110 has the same thickness. Since each acoustic board 110 has the same width and thickness, and different lengths, the respective natural frequencies are different, and thus the scale of the sound that is emitted when vibrating is different. .

  The pedestal part material 12 is a wooden material for making a pedestal part 120 described later. On one plate surface of the base material 12 having a required thickness, a groove 121, a groove 122, and a groove 123, which are three kinds of grooves having a required depth, are formed.

  A total of four grooves 121 are provided in parallel to the respective edges at locations that are separated from the respective edges of the base material 12 by the required width toward the center of the plate.

  The groove 122 is linear, cornered at 45 ° from the corner of the base material 12 to the center side of the plate so as to intersect two adjacent edges across the corner at 45 °. One copy is provided for each copy, and a total of four are provided.

  The groove 123 is linearly provided at a position between the corner of the base material 12 and the groove 122 so as to intersect two adjacent edges at 45 ° with the same corner interposed therebetween, and is 1 for each corner. Four books are provided in total.

  A hole 131 is formed in the rolling element 130. The hole 131 is formed in the direction of the sphere center of the rolling element 130.

  In this embodiment, the acoustic board 110 uses a cypress material, the dimensions are a width of 30 mm and a thickness of 2 mm, and the length of each (8 sheets) is 150 mm (the longest), 140 mm, 130 mm, 120 mm, and 110 mm. , 100 mm, 90 mm, and 80 mm (shortest), but are not limited thereto, and the material and dimensions can be changed as appropriate. Note that wood is preferably used from the viewpoint of ease of processing, recycling, and the like, but is not limited to this, and does not exclude the use of known materials such as bamboo and synthetic resin.

  In this embodiment, the pedestal part material 12 uses a hinoki material, and the dimensions are 95 mm in length, 95 mm in width, and 15 mm in thickness. However, the present invention is not limited to this, and the material and dimensions can be changed as appropriate. it can. The pedestal portion material 12 is also preferably made of wood, like the acoustic board 110, but does not exclude the use of known materials such as bamboo and synthetic resin.

  In the present embodiment, the rolling element 130 uses a hoo material and has a diameter of 22 mm. However, the present invention is not limited to this, and the material and dimensions can be changed as appropriate. The rolling elements 130 are preferably made of wood, like the acoustic plate 110, but the use of known materials such as bamboo, synthetic resin, glass, and metal is not excluded. Moreover, although the rolling element 130 is spherical, for example, it may be a polyhedron such as a icosahedron.

  In this embodiment, the heel shaft 141 uses a pine material, and the dimensions are 180 mm in length and 5 mm in thickness. However, the present invention is not limited to this, and the material and dimensions can be changed as appropriate. In addition, although the timber 141 is also preferably made of wood like the acoustic plate 110, the use of known materials such as bamboo and synthetic resin is not excluded.

  In the present embodiment, the rolling element 130 is employed as a member that rings the acoustic board from the inside. However, the present invention is not limited to this, and is, for example, a coin-like member that slides on the upper surface of the pedestal portion to generate sound. It may be one that can be applied to the inside of the plate, and its shape is not particularly limited.

  Moreover, it is preferable to form the part which strikes the acoustic board of a rolling element or a housing | casing with a raw material harder than an acoustic board so that a good sound may come out.

(Work)
With reference to FIG. 2 thru | or FIG. 4, the effect | action of the educational toy kit 1 is demonstrated.
The operator uses the saw S to cut off the right triangular triangular shaded portion of each corner shown in FIG. 2 along the groove 123 of the base material 12 (see the left diagram in FIG. 2). . At this time, since the groove 123 serves as a mark indicating a place where the saw S is ground, it is easy to work and there are few failures in the work.

  The base material 12 after the work of cutting the four shaded parts becomes an octagonal base 120 (see the right side of FIG. 2). At this time, an octagonal groove formed by combining the grooves 121 and 122 is formed in the pedestal portion 120, and this groove serves as a groove for inserting one longitudinal end portion of the acoustic plate 110.

  The circular xylophone X, which is an educational toy, is completed by inserting one end portion of each acoustic board 110 in the groove 121 and the groove 122 of the pedestal portion 120 (see FIG. 3). In addition, you may adhere the location which attached each acoustic board 110 to the base part 120 with the adhesive agent etc. In addition, the acoustic plates 110 can be arranged at random or can be arranged so as to become longer in order.

  Since the circular xylophone X has a configuration in which one end portion in the longitudinal direction of each acoustic plate 110 is inserted into the groove 121 and the groove 122 of the pedestal portion 120, the acoustic plate 91 is simply attached to the outside of the pedestal 92 with an adhesive 93. As compared with the conventional circular xylophone 90 (see FIG. 10B), each acoustic plate 110 is less likely to be detached from the pedestal portion 120.

  Further, the circular xylophone X may be sanded and polished before assembling the plate surface and side surface of the acoustic plate 110, the end surface after cutting the pedestal portion 120, and the like. Furthermore, a work for forming a notch or the like in the acoustic plate 110 may be performed, and a different way of enjoying that the sound generated by the shape change is changed.

  In the circular xylophone X, a rolling element 130 is placed in an inner region surrounded by each acoustic plate 110 and the pedestal portion 120, and a sound is produced by rolling so as to hit each acoustic plate 110 (see FIG. 4A). . Here, since each acoustic board 110 is different in length, it emits various sounds with different scales.

  In addition, the rolling element 130 can also be made into the casing 140 by inserting and attaching the tip of the flange shaft 141 to the hole 131 of the rolling element 130. The sound may be emitted from the circular xylophone X by hitting each acoustic board 110 using the casing 140. Further, the casing 140 can be used for either a method of making a sound by tracing the inner surface of each acoustic plate 110 or a method of making a sound by hitting the outer surface of each acoustic plate 110 (see FIG. 4 (b)).

  According to such an educational toy kit 1, interest in wood and its processing technology can be increased through processing or assembly work. The educational toy kit 1 requires an operation of processing the pedestal part material 12 into the pedestal part 120 and has a medium difficulty level. For example, the educational toy kit 1 can be suitably used as an educational material for middle school grades or higher.

  The processing mark 127b is linearly so as to intersect at 45 ° with respect to two adjacent edge portions across the same corner portion at a position away from the corner portion of the pedestal portion material 12b to the center side of the plate by the required width. 1 groove (4 in total) provided for each corner, groove and plate provided linearly so as to intersect the edge at 45 ° at a required position of the longitudinal edge of the base material 12b It is comprised from each of the groove | channel which divides the contact location of the adjacent regular octagon formed on a surface.

(Work)
By cutting along a processing mark 127b (a portion indicated by a broken line in the left side of FIG. 9) formed in parallel with the short direction of the pedestal portion material 12b, a pedestal portion material 12c is obtained. And if it cut | disconnects along the process mark 127b formed in the corner | angular part vicinity of the base part raw material 12c, the base part 120a will be obtained.

  The pedestal portion material 12b includes, for example, four sets (32 pieces in total) of acoustic boards (or acoustic board materials), rolling elements, shafts, etc. to provide four sets of educational toy kits 1a or educational toy kits 1b. It may be set.

  When the pedestal part material 12b shown in FIG. 9 is processed, the pedestal part 120a is obtained. For example, the inner lid body described above is formed at the center of each regular octagon formed by the processing mark 127b on the plate surface of the pedestal part material 12b. The pedestal portion 120b may be obtained by forming a bottomed circular mounting hole 128 that is a portion into which one end of the mounting shaft 151 is inserted.

  The pedestal portion material 12b shown in FIG. 9 is configured so that four pedestal portion materials 12c are obtained after cutting. However, the present invention is not limited to this. For example, two to three, five or more pedestal portion materials 12c are used. So that the length of the plate may be extended in the length direction or the width direction.

  In this specification and claims, the term “acoustic plate material” requires a finishing process, and can be rephrased as a semi-processed product. Similarly, the “pedestal part material” also requires a finishing process. In other words, it can be called a semi-processed product.

  The pedestal part 120 may be chipped when a strong force is applied to the outer region of the groove 121 or the groove 122. Therefore, it is more preferable to employ the pedestal part 120a or the pedestal part 120b. This is because the pedestal part 120a or the pedestal part 120b is formed with a necessary interval between the adjacent insertion holes 125, and the strength against the load is increased.

  When the educational toy kit 1 is a combination of the acoustic board material 11 or the acoustic board material 11a and the pedestal part material 12, the pedestal part material 12a or the pedestal part material 12b, the acoustic board material 11 (11a) and Since the work of processing the base material 12 (12a, 12b) into the acoustic board 110 and the base 120 (120a, 120b) is relatively difficult, it is suitable, for example, as an educational material for junior high school students, high school students, and elementary school upper grades. Can be used for

  The educational toy kit 1 may be a combination of the acoustic board material 11 or the acoustic board material 11a and the pedestal part 120 or the pedestal part 120b. In this case, the acoustic board material 11 (11a) is used. Since the work to process the acoustic board 110 is required and the degree of difficulty is moderate, it can be suitably used, for example, as an educational material for upper secondary school grades.

  Thus, the educational toy kit 1, the educational toy kit 1a or the educational toy kit 1b and its modified examples (hereinafter referred to as “educational toy kits 1, 1a, 1b, etc.”) are so-called semi-finished products (semi-processed products). An educational toy is completed by carrying out woodworking by itself. For this reason, the children who use the tools themselves use tools and devise their own processes and processing methods through the processing of the educational toy kits 1, 1a, 1b, etc., resulting in interest in wood and its processing technology. Can deepen. In addition, it is expected to have an educational effect that the interest in making things is stimulated and that people are interested in making various other things.

  Furthermore, since the educational toy kits 1, 1a, 1b, etc. use wood, the background to the person instructing the work until the materials of the educational toy kits 1, 1a, 1b, etc. are produced. Explaining this can also be expected as a tool that can be developed into environmental education.

  The terms and expressions used in the present specification and claims are for illustrative purposes only, and are not limiting at all. Features described in the present specification and claims. And there is no intention to exclude terms and expressions equivalent to those. It goes without saying that various modifications are possible within the scope of the technical idea of the present invention.
