Description

Technical Field

[0001] The present invention relates to the technology of the orin, which is a Buddhist implement.

Background Art

[0002] An orin is known as a Buddhist implement that is placed on an altar or the like and produces a sound when struck with a rin stick. There are also orins made of pure gold or the like to meet the demand for a sense of luxury. Orins made of precious metals tend to have a softer timbre than those made of brass. Some users prefer the timbre of orins made of precious metals, while others prefer the timbre of orins made of brass.

[0003] Among such diverse user preferences, in order to meet the desire to change the timbre when the orin is sounded, a bowl-shaped orin made of a precious metal (gold, silver, platinum) or an alloy containing at least one of these is manufactured through a casting process and a forging process. The inner peripheral surface of the orin is made substantially hemispherical, and the outer peripheral shape of the open end is octagonal, so that a technique is known that can provide an orin whose timbre can be changed according to the position where it is struck with a rin stick (see Patent Document 1).

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in the prior art disclosed in Patent Document 1 and the like, since the thick part of the bowl-shaped member is not hollow, it can only produce a sound when striking a member filled with metal, and it has been difficult to meet the needs of users who prefer the unique sound of hollow. Furthermore, the density of gold is very high at 19.32 g / cm³, and the density of platinum is 21.45 g / cm³. Compared to iron (approximately 7.9 g / cm³), gold is said to feel more than twice as heavy. In the conventional technology disclosed in the above-mentioned Patent Document 1, the bowl-shaped member is not hollow, making it heavy, and there were limitations to reducing its weight. Moreover, it is conceivable that the bell may fall from the altar during earthquakes, etc., so there were also limitations to stabilizing it through weight reduction. Furthermore, because gold and other precious metals have been considered valuable since ancient times, they are extremely expensive. From an economic standpoint, the thickness of the thicker parts of the bowl-shaped components tends to be thinner, which is said to have a tendency to worsen the tone quality. In particular, in recent years, the price of gold and other materials has soared, increasing costs and sometimes making them unaffordable for users. In this regard, addressing this issue by applying gold or other plating can lead to a lack of psychological satisfaction due to the perception of cheapness, and there are also problems with the plating peeling off due to aging and deterioration. Furthermore, in the prior art disclosed in Patent Document 1 and other documents mentioned above, the bowl-shaped members were processed by skilled technicians, often referred to as "master craftsmen," by hammering sheet metal, resulting in a long processing time of about one month. In addition, there were problems such as the cost of training such technicians to become skilled, variations in quality and delivery time depending on the skill of the technician, and the scarcity of skilled technicians in the first place.

[0006] The objective of this invention is to provide a Buddhist bell that produces a unique sound, is lightweight and stable, reduces costs by decreasing the amount of raw materials required, and can be manufactured by anyone in a short period of time without requiring any special skills. [Means for solving the problem]

[0007] The present invention's orin (Buddhist bell) is made of gold and platinum or an alloy using at least one of gold and platinum. The upper edges of a first substantially vessel-shaped member forming a pre-formed outer layer and a second substantially vessel-shaped member forming a pre-formed inner layer are connected. It is a hollow, two-layered bell formed in a roughly vessel-like shape. [Effects of the Invention]

[0008] According to the present invention, it is possible to provide a Buddhist bell that produces a unique sound, is lightweight and stable, reduces costs by decreasing the amount of raw materials required, and can be manufactured by anyone in a short period of time without requiring any special skills. [Brief explanation of the drawing]

[0009] [Figure 1] This diagram shows the configuration of an orin (Buddhist bell) in an embodiment of the present invention. [Figure 2] This is a cross-sectional view AA of the orin (bell) in an embodiment of the present invention, shown in Figure 1. [Figure 3] This is a cross-sectional view of the bell (orin) in an embodiment of the present invention, shown as BB in Figure 1. [Figure 4] This figure illustrates a method for manufacturing an orin (a type of Buddhist bell) according to an embodiment of the present invention. [Modes for carrying out the invention]

[0010] Hereinafter, an embodiment of the present invention, specifically the bell 1, will be described with reference to the drawings. Note that any parts that overlap with the prior art relating to the conventional products described above will be omitted as appropriate.

[0011] The orin 1 in this embodiment shown in Figure 1 is formed in a roughly vessel shape (typically a bowl shape). More specifically, the inner circumferential surface of the orin 1 is roughly hemispherical, i.e., spherical. Therefore, the inner circumferential shape of the open end of the orin 1 is circular. The inner circumferential surface may also be roughly semi-ellipsoidal, etc.

[0012] The material of the orin 1 in this embodiment shown in Figure 1 is an alloy using gold and platinum or at least one of gold and platinum. For example, pure gold (24k), 22k, 18k, 16k, etc., or pure platinum (Pt999), Pt950, etc.

[0013] In this embodiment shown in Figure 1, the orin 1, as also shown in Figures 2 and 3, has a roughly bowl-shaped thick section that is hollow, and includes a hollow region 2, forming a so-called hollow two-layer structure. The hollow region 2 may be the entire roughly bowl-shaped thick section or a part of it. Furthermore, the ratio of the hollow region 2 to the thickness of the roughly bowl-shaped thick section (for example, if the total thickness of the thick section is 8 mm, and the outer layer is 2 mm, the inner layer is 2 mm, and the hollow region 2 is 4 mm, the ratio is 1 / 2 = 50%) is also arbitrary.

[0014] Next, with reference to Figure 4, the manufacturing method of the orin 1 in this embodiment will be described. This explanation assumes the manufacture of a bowl-shaped orin (Buddhist bell) made of pure gold (24-karat gold). In essence, a hollow two-layer structure is achieved by forming two bowl-shaped members, one forming the outer layer and the other the inner layer, and connecting their upper edges.

[0015] More specifically, as an example, first, a single sheet of pure gold (24-karat gold) that has been rolled into a plate shape by pressing or roller rolling is hammered and compressed to deform it, or drawn while rotating to form the first bowl-shaped member 11. Next, in the same manner as above, a second bowl-shaped member 12 is formed by hammering and compressing another sheet metal to deform it into a bowl shape, or by drawing it while rotating it. The bowl-shaped member 11 is formed to be slightly larger than the bowl-shaped member 12. For example, if the thickness dimension of the hollow region 2 is 4 mm, the bowl-shaped member 11 will be formed to be approximately 4 mm larger in radius, etc., than the bowl-shaped member 12. Then, the bowl-shaped member 11 is positioned to form the outer layer and the bowl-shaped member 12 is positioned to form the inner layer, either by machine or by hand, and the upper edges of both are connected to obtain a hollow two-layer structured bell 1. The upper edges of the two parts may be joined mechanically or manually by heat-based welding such as laser or brazing, or by joining them using additional pure gold (24-karat gold) in a soldering manner. The method is not particularly limited as long as the upper edges of the two parts are joined, and various known methods may be applied.

[0016] According to the above-described embodiment of the present invention, unlike the prior art, there is no metal clogging in the thick part and the inside is hollow. Therefore, like a drum, the sound reverberates and a muffled sound is likely to occur. When hitting the substantially vessel-shaped (bowl-shaped) part from the side with a rin stick, a unique sound is produced. Since individuals have diverse hobbies and different preferred sounds, it is possible to meet the needs of users who prefer the unique hollow sound. The afterglow (reverberation) is also unique. That is, when the rin stick hits, a noisy sound mixed with sounds of various frequencies (tones) is instantaneously generated, and then several sounds (partial tones) of various frequencies remain to form a unique afterglow. In addition, since there is no metal clogging in the thick part as in the prior art, the weight is reduced by the amount of the hollow part, and weight reduction can be achieved. Furthermore, in the event of an earthquake or the like, it is assumed that the orin may fall from a Buddhist altar or the like, and stabilization due to weight reduction can be achieved. In addition, these days, the prices of gold and the like are soaring. Since the raw materials are not required by the amount of the hollow part, cost reduction can be achieved, and the price can be suppressed to a range that is easy for consumers to afford. In addition, no skill is required for processing. Especially when using a machine, anyone can manufacture it in a short period of time. Conventionally, since a skilled person (a master craftsman) is in charge of processing, the processing cost tends to be high. If a machine is used to reduce the labor cost, the product can be provided at a lower price.

[0017] In addition, although not exemplified one by one, the present invention may be implemented with various modifications within the scope not departing from the gist thereof. The size, shape, material, position, etc. of each component member can be appropriately changed as long as the effects of the present invention are achieved. The modification examples specifically described in the above description are just examples, and modification examples not described are not excluded, nor is any particular meaning given to the importance of their handling.
