BACKGROUND OF THE INVENTION
The present invention relates to the structure of a mysterious bowl, which is a percussion instrument used in ceremonies such as legal matters in Nichiren Buddhism, a Buddhist sect.
[0002]
[Prior art]
Myochi is a cymbal percussion instrument that is prepared by striking a 70% copper and 30% zinc alloy plate with a scissors. However, because the palm-gripped part has a bay-like shape, it cannot be manufactured with a press or the like, and most of them are hand-made by traditional hammering.
[0003]
[Problems to be solved by the invention]
Usually, in the Buddhist legal essence, Myochi is used as a percussion instrument that strikes the left and right bowls in a cymbal shape and makes a sound of jerking.
However, in the rituals such as the law of Nichiren Buddhism, a Buddhist sect, the edges of a pair of left and right dish-shaped bowls are rubbed together to generate a rubbing sound called shyen and used in combination with a copper casket.
Thus, in order to make a sound by sliding the left and right bowls, it is necessary to rotate the left and right bowls with the wrist, palm, and fingertips to idle.
In this way, when the edges of the bowls are rubbed together to make a shy sound in the legal process, monks who have been used to using the pots for a long time can turn the pots without difficulty due to many years of skill. It can be done.
[0004]
However, a priest with a short training time cannot easily spin the left and right bowls with the shaft string as the axis.
This is because when the prince creates a majestic atmosphere in the legal requirements, the monk is concerned about the operation of the mysterious bowl, and the reading and so on are obscure, and the atmosphere of the majestic ritual is whitened.
The present invention makes it possible for even an unskilled monk to reliably perform the operation of making a shingling sound by rubbing mysterious pots that play an important role in such Nichiren Buddhist rituals.
In addition, in the case of a strange bowl that is difficult to turn as in the prior art, the strange bowl rotates around the string at the part of the eyelet provided in the center of the bowl, but due to the friction between the eyelet and the string, Since there is a case where the string is cut, it is intended to solve the problem that such a string is cut.
[0005]
[Means for Solving the Problems]
The present invention solves the problems of conventional pots.
In the Myochi bowl, which is a percussion instrument used in legal matters, the eyelet 5 through which the shaft string 4 can pass is fitted into the center holes of the left and right bowls A, A constituting the Myochi bowl, The shaft core 4 is configured to pass through the configured shaft string 4, and a thrust bearing B is provided on the outer periphery of the shaft string 4 between the end of the shaft string 4 protruding inside the bowl A and the inner surface of the bowl A. Further, washers 7 and 7 are arranged on both sides of the thrust bearing B on the outer periphery of the shaft string 4, and the thrust bearing B is disposed on the annular portion of the outer periphery of the doughnut-shaped ball holder 10. The receiving ball 9 is loosely fitted by a retainer so that the thrust receiving ball 9 protrudes on both the left and right sides of the ball holder 10, and the washers 7 and 7 are in contact with both sides of the thrust receiving ball 9. It is comprised so that it may correspond .
[0006]
DETAILED DESCRIPTION OF THE INVENTION
Next, an embodiment of the present invention will be described.
FIG. 1 is a perspective view of a state in which left and right mystic pots according to the present invention are arranged, and FIG.
[0007]
FIG. 3 is a cross-sectional view of one of the bowls, FIG. 4 is an enlarged cross-sectional view showing a bearing portion of the string of one of the bowls, and FIG. 5 is a side view of a state where a thrust bearing portion that facilitates the rotation of the bowls is taken out. It is.
[0008]
6 is a cross-sectional view of the eyelet fitted in the pivotal support hole of the bowl, FIG. 7 is a perspective view of the receiving metal 1 that receives the thrust bearing, and FIG. 8 is a perspective view of the thrust bearing B.
[0009]
FIG. 1 is a perspective view showing a pair of left and right states of the mysterious bowl of the present invention.
Myochi is a percussion instrument for religious ceremonies that produces a cymbal-like jerking sound by striking the left and right sides of the bowl, usually facing the left and right bowls of the same shape.
However, in Nichiren Buddhism, the left and right bowls A and A are rotated in opposite directions, and the edges of bowl A are slid together rather than playing with a shocking sound from left and right. There are more ways to make long sounds.
[0010]
For many years, a priest wearing a playing technique that produces sound by rubbing the edges of a mystic pot can easily perform a playing technique in which the left and right bowls A and A are idled. In this case, hang palms on the bowl-shaped protrusions of the left and right bowls A and A, pass an axial string between the index finger and thumb, and place the back plate 3 of the back of the hand against the back of the hand. By rotating the fingertips, the left and right bowls A and A can be reversely rotated in the opposite direction at a considerable number of rotations around the shaft string 4.
When the rotation is stopped, the gap between the index finger and the thumb is narrowed, and the palm is strongly pressed against the palm contact protrusion 6 to stop the rotation.
[0011]
However, in the case of an inexperienced monk, if he puts his palm between the back plate 3 of the back of the hand and the left and right bowls A and A and tries to rotate the left and right bowls A and A with his fingertips, Since the shaft string 4 cannot be arranged at the center of the left and right bowls A and A so that the frictional force with the left and right bowls A does not occur, the left and right bowls A in an eccentric state and the shaft string 4 are Since it rubs strongly, the rotation of the left and right bowls A immediately stops, so that a shingling sound that rubs the edges cannot be generated, and the ceremonial dignity is broken.
[0012]
In addition, as a result of trying to forcefully rotate the left and right bowls A in a state where the axis string 4 and the center position of the left and right bowls A do not match, the center hole of the left and right bowls A is formed in the axis string 4. There was also a problem that the shaft string 4 was cut by contact in a frictional state.
In the present invention, a large eyelet 5 is fitted in the center of the left and right bowls A so that the shaft string 4 is not cut by friction at the contact portion with the shaft string 4, and By inserting a thrust bearing B between the receiver 1, the left and right bowls A can be easily rotated by a rotation operation with a fingertip, even for a less experienced monk.
[0013]
As a result, even a novice monk can rotate the left and right bowls A and A in the opposite direction without failure, and can proceed with reading without worrying about the operation of the mysterious bowl during the ritual. It did not fail to rotate the mysterious bowl, and it no longer lost the solemnity of the ritual.
[0014]
In FIG. 1, reference numeral 2 denotes a decorative string, and the shaft string 4 and the decorative string 2 are connected to the outside of the back plate 3 of the back of the hand. And the part of the shaft string 4 passes through the hole at the center of the bowl A and also passes through the hole of the eyelet 5 fitted in the hole at the center of the bowl A to serve as the shaft.
The left and right bowls A have a configuration in which a bowl-shaped palm contact projection 6 is struck out on the outside. The bowl-shaped palm contact projection 6 has an inlet opening smaller than the inner diameter. It cannot be processed by press working, but has a structure manufactured by hammering out manually.
[0015]
The bearing mechanism on the outside of the shaft cord 4 of the present invention is configured inside the hook-shaped palm contact projection 6.
Then, monk, when performing playing making sounds that Shain by allowed Awa sliding edge, as shown in FIG. 4, put hands between Jikuhimo 4 and bowl-shaped palm abutment protrusions 6, The hook-shaped palm contact protrusion 6 is rotated by a fingertip.
Thus, when putting a hand and rotating the bowl-shaped palm contact protrusion part 6 with a fingertip, depending on the condition of the position of the center hole of the shaft 4 or the back plate 3 of the back of the hand and the left and right bowl A The left and right bowls A can no longer generate sufficient idle rotation.
In the present invention, inside the hook-shaped palm contact projection 6, two receivers 1, 1 are interposed on the shaft string 4, and the thrust is interposed between the two receivers 1. A washer 7 and 7 of the bearing B are interposed, and a thrust bearing B is interposed between the washers 7 and 7.
Then, the shaft cord 4 is passed through the hole in the center of the series of annular bodies constituted by the washer 1, washer 7, thrust bearing B, washer 7 and the washer 1, and the shaft cord 4 is passed through the inner end portion. The knot 8 is constructed.
[0016]
The money receiver 1 that plays an important role in the above configuration is illustrated in FIGS. 5 and 7. A central axial hole 1a of the plate-shaped metal plate is formed, and the axial cord 4 is passed through the axial core hole 1a. The receiver 1 is configured in the shape of a dish, and the inner receiver 1 is configured such that the wider one is applied to the inner surface of the bowl-shaped palm contact projection 6 of the left and right bowls A, and the thrust bearing is formed in the narrower one. B washer 7 is applied.
Further, the receiver 1 closer to the knot 8 has the knot 8 applied to the narrower side and the washer 7 applied to the inner side of the wider one.
A thrust bearing B is interposed between the washers 7 on both sides.
[0017]
As shown in FIG. 8, the thrust bearing B is loosely fitted to the annular portion of the outer periphery of the doughnut-shaped ball holder 10 by a retainer so as to prevent the thrust receiving ball 9 from coming off. The thrust receiving ball 9 has spherical outer peripheral surfaces protruding on both the left and right sides of the ball holder 10, so that washers 7, 7 arranged on both sides are in contact with both sides of the thrust receiving ball 9. It is composed.
The structure of the washers 7 and 7 and the thrust bearing B allows the thrust bearing B to support the bearing without receiving any resistance or friction even when the washers 1 and the washers 7 on both sides rotate. It is doing.
[0018]
Further, as shown in FIG. 6, the eyelet 5 of the present invention is constituted by a trapezoidal eyelet 5 so that the fibers of the shaft string 4 are not scraped off by friction when contacting the outer periphery of the shaft string 4. ing. By fixing the eyelet 5 by fitting the eyelet 5 in the center hole of the left and right bowls A and hitting the hem portion protruding inward in a direction in contact with the inner surface of the left and right bowls A, the eyelet 5 is fixed. It is.
A long time ago, there is a mystic pot, and there are old mystic pots in temples, etc., but for the monks with less recent experience, in the old-fashioned mystic pot, the thrust bearing B part and the receiver 1 part Because there is no, there is not enough idle rotation.
In addition, in order to apply the force of turning with your fingertips in a state where it is difficult to rotate freely, in the case of the old core hole of the left and right bowl A or the thin eyelet, the shaft string 4 is scraped off. As a result, during the ritual, the left and right bowls A with broken strings fell, making a loud noise and breaking the solemn atmosphere.
[0019]
In the present invention, the eyelet 5 of the old-fashioned left and right bowl A is replaced with a large one to eliminate fraying due to friction between the shaft 4 and the eyelet 5, and a hook-like palm-contact projection. Between the knot 8 inside the portion 6 and the inner surfaces of the left and right bowls A, the two catches 1, the two washers 7 and 7, and the thrust bearing B at the center are interposed. Even for beginners, the left and right bowls A and A can be simply rotated freely in the left and right directions by operating the bowl-shaped palm contact protrusion 6 with a fingertip.
[0020]
【The invention's effect】
Since the present invention is configured as described above, the following effects can be obtained.
First, in Myohachi a percussion instrument used in Buddhist, the outer circumference of Jikuhimo 4 constituting the axial center of the pot A constituting the left and right pot A · A, projecting inside the pot A Jikuhimo Since the thrust bearing B is interposed between the end of 4 and the inner surface of the bowl A , even a priest with little experience performs an operation of rotating the bowl-shaped palm-contact projection 6 with his fingertip. Therefore, the left and right bowls A and A can be easily rotated in the opposite direction, so that in the rituals such as legal matters, it is not necessary to take care of whether or not a shinging sound can be produced by sliding the edges. .
[0021]
Secondly, since the washers 7 and 7 are arranged on both sides of the thrust bearing B, the mechanism that rotates around the shaft cord 4 only by the thrust bearing B is used. In such a case, the rotation of the bowl A is first transmitted to the washer 7 on the side of the bowl A to cause idle rotation, and then idle rotation occurs between the washer 7 and the thrust receiving ball 9 of the thrust bearing B. Then, since the idle rotation occurs between the thrust receiving ball 9 and the washer 7 on the far side, the rotation of the bowl A does not drop due to the occurrence of the idle rotation at each portion. The rotational axis of A can be gradually made constant, the thrust bearing B, the washer 7 and the eyelet 5 do not come into contact with the shaft string 4, and the frictional force can be made close to zero. .
[0022]
Third, at the center of the pot A, the center hole passing through the Jikuhimo 4, since the fitted large eyelet 5 to Jikuhimo 4 and Setto, as is conventional, the center of the bowl A hole and Jikuhimo By forcibly rotating between 4 and 4, in the middle of the ritual, the shaft 4 was worn out, and the bowl A dropped, making an unexpectedly loud sound and no longer ruining the ritual. It is.
