Description

[Technical Field]

[0001] This invention relates to a thatched roof Shinto altar. [Background technology]

[0002] A kamidana is like a "small shrine" set up in a home or workplace, where people worship talismans and other items received at the shrine to express gratitude to the gods and pray for the safety of the household and prosperity of business. Kamidanas have a storage room for talismans, and people offer offerings of sakaki branches, water, rice, and other items before praying. For example, Patent Document 1 discloses a Shinto altar that can store anything from standard-sized talismans to long talismans very easily in a talisman storage compartment without the risk of damaging the talismans, and that has a simple structure and is inexpensive.

[0003] [Patent Document 1] Utility Model Registration No. 3191329 [Non-patent literature]

[0004] [Non-Patent Document 1] Miyachu Co., Ltd. Homepage <https: / / www.ise-miyachu.co.jp / SHOP / 266179 / 266185 / list.html?srsltid=AfmBOooSR2guysHorxJ6_FpcmDmKxt9VXe3kAaYKLDn1F-3mexRjGqpU> DISCLOSURE OF THE INVENTION [Problem to be solved by the invention]

[0005] Incidentally, the roof of the main hall of Ise Shrine is thatched, and is made primarily from the stalks K of thatch. If one were to create a Shinto altar modeled after the main hall and use the stalks K as the material for the thatched roof, the diameter of the stalks would become too large due to the scale, resulting in an unnatural structure. Therefore, when making thatched Shinto altars, the leaf part H of thatch has been used (Non-Patent Document 1). Figure 1 shows an outline of the stem part K, leaf part H, and tip S of a Japanese pampas grass with a total length of about 2 m as an example of thatch. Figure 2 shows (A) the tip S, (B) the leaf part H, and (C) the stem part K, all trimmed to lengths of 15 cm to 25 cm. As such, there is a large difference in diameter between each part.

[0006] In addition to being able to obtain multiple leaves H from a single Miscanthus stalk, one leaf can be used to create 2-4 thatched roofing materials. Therefore, it was possible to obtain 10-20 thatched roofing materials from a single Miscanthus stalk. Figures 3 to 6 show an overview of the process for manufacturing a thatched Shinto altar 100 using leaf parts H. As shown in Figure 3, one end of several dozen leaf parts H is fixed with string members 104 to form roof members 101. Next, as shown in Figure 4, roof members 101 are fixed to the top side of the roof base 103 of the Shinto altar main body 102, returning it to its pre-pruning state. Next, as shown in Figure 5, the tip side of roof member 101 is pruned to form trimmed edge 101A, and the overall shape is adjusted. Once all roof members 101 have been pruned, a fully thatched roof 105 is formed, as shown in Figure 6.

[0007] However, when collecting the dead pampas grass, some of the leaves (H) had turned black due to rain and frost, which resulted in uneven coloring of the thatched roof and some areas looking unattractive. Also, even if the leaves (H) were used, the openings in the thatched roof would be too large, creating a sense of incongruity in the scale. The present invention was made in consideration of the above circumstances, and its purpose is to provide a thatched Shinto altar that can reduce the sense of incongruity caused by the scale of the thatched roof. [Means for solving the problem]

[0008] After careful consideration, the inventor discovered that the sense of incongruity in the scale of a thatched roof could be reduced by narrowing the diameter of the plants used to make the thatch, and this led to the basic completion of the present invention. Thus, the thatched Shinto altar devised to achieve the above-mentioned objective is a Shinto altar equipped with a storage chamber for storing talismans, and thatched roofing is provided on the upper surface of the roof substrate, and the thatched roofing is preferably made of plant tips. With this configuration, compared to using leaves, the sense of incongruity regarding the scale of the roof of the thatched Shinto altar can be reduced, and unevenness in the color of the roof can be reduced. In the present invention, the plant is preferably at least one selected from the group consisting of Japanese silver grass, common reed, Imperata cylindrica, and Japanese laurel. In particular, by using the tips of Japanese silver grass, the color of the roof becomes golden, making it look even more attractive.

[0009] The tips of plants are very thin, and only one piece of material can be collected from one plant. In other words, compared to the leaf part H in Figure 1, only about one-tenth of the tips S can be obtained from one plant. For this reason, it is extremely inefficient for producing thatched Shinto altars, and no attempts have been made to produce thatched Shinto altars using the tips S until now. According to this invention, it has been found that using the tips S can provide many benefits, even if it requires a considerable amount of effort. [Effects of the Invention]

[0010] This invention can reduce the sense of incongruity of the scale of the thatched roof, make the color of the thatched roof uniform, and provide a golden thatched shrine. [Brief explanation of the drawings]

[Figure 8] This is a photograph of the Shinto altar before trimming when the roof members are fixed to the upper surface of the roof underlayment. [Figure 9] This is a photograph of the roof members after they have been trimmed and are now half-trimmed. [Figure 10] This is a photograph of the roof components when they are all removed. [Figure 11] This is a photograph of the completed thatched roof temple. [Figure 12] 1A and 1B are enlarged photographs showing the diameters of roof members in a conventional roof and a roof according to an embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0013] Next, the embodiments of the present invention will be described with reference to the drawings, but the technical scope of the present invention is not limited to these embodiments and can be embodied in various forms without changing the gist. In addition, the technical scope of the present invention extends to the range of equivalents. In this embodiment, the material for constructing the roof is the tips S of Japanese silver grass, as shown in Figures 1 and 2. A large amount of Japanese silver grass is cut, and the tips S are harvested and cut to an appropriate length. After that, as shown in Figure 7, more than 100 stalks are collected and fastened at the base with string 10 to produce roofing member 11.

[0014] 8 shows how the base portions of several tens to several hundred roof members 11 are fixed to the upper surface of the roof base 13 of the Shinto altar main body 12. In this way, the Shinto altar before pruning is manufactured. Next, the tips of the stalks S are trimmed to form the shape of a thatched roof. Figure 9 shows the tips trimmed to about 60-70% of their original length. This trimming process is done manually by skilled workers. Trimming the tips S to form a thatched roof requires more skill than conventional methods, as the elasticity of the tips is weaker than that of the leaf part H.

[0015] When the entire pruning work is completed in this way, the entire pruning state is reached as shown in Figure 10. The manufacture of the thatched Shinto altar 20 is completed by assembling any other necessary components. Figure 11 shows an overall view of the completed thatched Shinto altar 20. A storage chamber 30 for storing talismans is provided in the center of the thatched shrine 20. Figure 12 also shows a comparison between a pruned roof member 101A in the prior art and a pruned roof member 11A in this embodiment.

[0016] In this way, by using the tips S, the number of plants per unit area is about five times greater than that of the leaf portions H, so the diameter can be made smaller. In this way, the scale ratio between the roof member 11A and the thatched roof 21 is closer to the real thing, so there is less sense of incongruity and it is possible to create something that is closer to the image of the main hall. In addition, the thatched roof shrine 20 has a uniform color throughout the thatched roof 21, and is a brighter golden color compared to the color of the leaf portion H, making it look beautiful. Thus, according to this embodiment, it is possible to make the color of the thatched roof as uniform as possible, resulting in a good-looking golden color, and it is possible to provide a thatched Shinto altar in which the scale of the roof and roofing components does not seem out of place.
