Description

Technical Field

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

Background Art

[0002] The 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 high-class feeling. The orin made of a precious metal tends to have a softer sound than the orin made of brass. Some users prefer the sound of the orin made of a precious metal, while others prefer the sound of the orin made of brass.

[0003] In such a situation where the preferences of users diversify, in order to meet the desire to change the sound 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 for providing an orin capable of changing the sound according to the position struck with the rin stick is known (see Patent Document 1).

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in the conventional technology disclosed in the above 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 in which the metal is packed, 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 / cubic centimeter, and the density of platinum is 21.45 g / cubic centimeter. Compared to iron (approximately 7.9 g / cubic centimeter), 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. 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 first orin of the present invention is a hollow two-layer orin that is formed in a roughly bowl shape by connecting the upper edges of a first roughly bowl-shaped member that forms a pre-formed outer layer and a second roughly bowl-shaped member that forms a pre-formed inner layer. The material of the first roughly shaped member and the material of the second roughly shaped member are different metals.

[0009] Furthermore, the orin (Buddhist bell) of the present invention may have plating applied to at least some of its metal components. [Effects of the Invention]

[0010] 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]

[0011] [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 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]

[0012] 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.

[0013] 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. As can also be seen in Figure 4, the orin 1 in this embodiment has a hollow two-layer structure achieved by forming two bowl-shaped members, an outer layer and an inner layer, and connecting their upper edges.

[0014] In this embodiment shown in Figure 1, the material of the orin 1 is such that one of the two bowl-shaped members forming the outer and inner layers is an alloy of 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. The other of the two bowl-shaped members forming the outer and inner layers is a metal other than an alloy of gold and platinum or at least one of gold and platinum, such as pure silver or silver alloy, brass, copper, iron, stainless steel, aluminum, copper + zinc, copper + tin + lead, etc. The examples of pure silver or silver alloy, brass, copper, iron, stainless steel, aluminum, copper + zinc, copper + tin + lead, etc., are relatively easy to obtain, and their material properties are well known, making them highly convenient. The difference in hardness of the metals combined is clearly evident, and a variety of sounds can be achieved.

[0015] 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.

[0016] Next, with reference to Figure 4, the manufacturing method of the orin 1 in this embodiment will be described. 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. Here, we assume that the outer bowl-shaped component is made of pure gold (24-karat gold), and the inner bowl-shaped component is made of pure silver, in order to manufacture a bowl-shaped orin (Buddhist bell).

[0017] More specifically, as an example, first, a single sheet of sheet metal made of pure gold (24 karat) that has been extended into a plate shape by pressing, roller rolling, or the like is struck, compressed, and deformed, or is drawn while being rotated by drawing to form the first bowl-shaped member 11 (outer layer). Next, a single sheet of sheet metal made of pure silver that has been extended into a plate shape by pressing, roller rolling, or the like is struck, compressed, and deformed into a bowl shape, or is drawn while being rotated by drawing to form the second bowl-shaped member 12 (inner layer). The bowl-shaped member 11 (outer layer) is formed to be slightly larger than the bowl-shaped member 12 (inner layer). For example, when the dimension in the thickness direction of the hollow region 2 is 4 mm, the bowl-shaped member 11 is formed such that its radius and the like are about 4 mm larger than those of the bowl-shaped member 12. Then, after the bowl-shaped member 11 forms the outer layer and the bowl-shaped member 12 forms the inner layer, they are respectively arranged at positions such that the upper end edges of both are connected to obtain the o rin 1 having a hollow two-layer structure. Note that the connection of the upper end edges of the above two may be by welding using heat such as laser or brazing by mechanical or manual operation, or by joining using additional pure gold (24 karat), pure silver, or the like in the manner of soldering. As long as the upper end edges of both are connected, the method is not particularly limited, and various known methods may be applied. Furthermore, plating with an arbitrary metal material may be applied to the second bowl-shaped member 12 (inner layer) made of pure silver and the connection portion. In this embodiment, gold plating may be applied only to at least a part of the inner surface of the second bowl-shaped member 12. If the bowl-shaped member 11 (outer layer) is made of pure silver, gold plating may be applied only to at least a part of the outer surface of the bowl-shaped member 11. By applying plating such as gold plating or platinum plating in this way, it becomes possible to create a sense of unity in the appearance color, to be beautiful, and to be used generation after generation without corroding for many years. Note that the plating does not necessarily need to be a color that creates a sense of unity in the appearance color and may be arbitrarily selected.

[0018] According to the above-described embodiment of the present invention, unlike the prior art, there is no metal clogging in the thick portion, and since the interior is hollow, it is easy for a sound to reverberate like a drum and a muffled sound to occur. When hitting the substantially vessel-shaped (bowl-shaped) portion horizontally with a mallet, a unique sound is produced. Since individuals' interests are diverse and their preferred sounds are different, it is possible to meet the needs of users who prefer the unique sound of the hollow. The afterglow (reverberation) is also unique. That is, when the mallet hits, a noisy sound mixed with sounds of various frequencies (frequencies) is instantaneously generated, and then several sounds (partial sounds) of various frequencies remain to form a unique afterglow. In addition, since there is no metal clogging in the thick portion as in the prior art, the weight is reduced by the amount of the hollow portion, 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 an altar or the like, and stabilization due to weight reduction can be achieved. Also, these days when the prices of gold and the like are soaring, the raw materials are not required by the amount of the hollow portion, cost reduction can be achieved, and the price can be suppressed to a price range that is easy for consumers to obtain. By using a precious metal for either the inner layer or the outer layer and using a relatively inexpensive metal for the other side, further cost reduction can be achieved. 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 and the labor cost is reduced, the product can be provided at a lower price. Furthermore, it is easy to adjust the thickness of appropriate parts of the "first substantially vessel-shaped member forming the pre-formed outer layer" (for example, making the area near the middle of the height position thicker on the outside or inward to create a bulging shape), or to adjust the thickness of appropriate parts of the "second substantially vessel-shaped member forming the pre-formed inner layer" (for example, making the area near the middle of the height position thicker on the outside or inward to create a bulging shape). Based on the shapes of the outer and inner layers, the upper edges of both are connected to form a substantially vessel-shaped hollow "orin," and striking the hollow "orin" with a stick produces a "unique sound" that matches the tastes of various consumers, as the tone is determined by a combination of multiple harmonics superimposed on the fundamental tone. Conventional orin (Buddhist bells) are made from a single metal, and techniques such as forging are used to alter the tone, resulting in a limited range of tones. However, according to this embodiment, it is possible to reproduce a variety of tones by changing the type of metal used for the outer and inner layers, or by changing the thickness of the outer and inner layers. Furthermore, the double-layered structure allows for the expectation of resonant sounds.

[0019] Furthermore, although not exemplified here, the present invention may be implemented with various modifications without departing from its spirit. The size, shape, material, position, etc., of each component can be changed as appropriate, as long as the effects of the present invention are achieved. The modifications specifically mentioned in the above description are merely examples, and modifications not mentioned are excluded, nor is any particular significance assigned to the relative importance of those modifications.
