Description

  The present invention relates to a winder for a string winding device of a stringed instrument such as a guitar.

  For stringed instruments such as guitars, string winding devices for winding the string around the head part H and winding it back to stretch the string, or adjusting the tension to adjust the string, are attached according to the number of strings. ing. As shown in FIGS. 8 and 9, the string winding device 100 includes a winding shaft 102 that winds the string, and a knob 104 that rotates the winding shaft 102, and rotates the knob 104 around the axis. Thus, the winding shaft 102 connected through a gear or the like is rotated to wind the string, and the string is exchanged or tuned while being rewound.

When exchanging and tuning strings, it is necessary to perform such string winding and rewinding operations according to the number of strings. For each of the many string winding devices 100, the knob 104 is directly hand-held. If it is picked and rotated, it takes time and fingers become painful. For example, as shown in FIGS. 8 and 9, a winder 200 for a string winding device may be used (see Patent Document 1). . A conventional winder winding device 200 includes a receiving portion 202 for inserting the knob 104 into an internal rectangular parallelepiped hollow space 203 from an opening 201, and an extending portion integrally extended in the longitudinal direction of the receiving portion 202. 204, and a handle 205 having one end side pivoted about an axis at the extended end of the extended portion 204. With the handle 104 held in the receiving part 202 while the knob 104 of the string winding device 100 is received, the handle 205 is rotated by hand to rotate the knob 104 so that the winding shaft 102 winds and rewinds the string. Met.

  As shown in FIG. 8, for example, when replacing a string, when winding a new string around the string winding device 100, the leading end side of the new string is first inserted into the hole of the winding shaft 102 before the winding operation. It is necessary to perform a hitch operation such as inserting, folding the leading end side of the inserted string, passing back the lower side of the original string, and further winding the string upward on the original side of the string. Such hitch work is a fine work, and is a work using both hands. However, in the conventional winder 200, the knob 104 is merely inserted into the hollow space of the receiving portion 202 from the opening 201, and the balance is poor due to the handle attached in a protruding shape. When the hand was released from 200, the winder 200 was easily detached from the knob 104, and it was easy to fall on the floor. Therefore, when the hitch work is performed, the winder 200 needs to be removed from the knob 104 and placed on a table or a knee. Therefore, when shifting from the hitch operation to the winding operation of the string winding device 100 by the winder 200, the leading end side of the string is held with one hand and placed on a table or the like with only the other hand. Since it is necessary to take the winder 200 and attach it to the knob 104, the overall work is complicated, and a quick and smooth work cannot be performed, which takes time. In addition, when the winder 200 is quickly rotated, the operation tends to be rough. However, at this time, the receiving unit 202 is easily detached from the knob 104, so that the quick operation cannot be performed and the operability is poor. there were.

  The present invention has been made in view of the above-described conventional problems, and one object of the present invention is to prevent it from coming off from the pick naturally when attached to the pick of the string winding device, and winding and rewinding the string. It is an object of the present invention to provide a winder for a string winding device for a stringed instrument that can be operated satisfactorily.

  In order to solve the above-described problems, the present invention relates to a container body 12 having an operation unit for rotating the knob 104 of the string winding device 100 for a stringed musical instrument, and the instrument body 12 detachably attached to the knob 104 of the string winding device 100.

An engaging device, and the engaging device is capable of engaging and disengaging the device body with respect to the knob, and is supported by the entire device body with respect to the knob in the engaged state, and the co-rotation of the device body and the knob. Therefore, for example, even when the hand is released from the winder, the body is supported by the knob without being detached from the knob, and the container is attached to the knob. As a result of being able to use both hands freely, for example, between the work of using both hands, such as hitching work before winding a new string, and the turning operation of the knob with a winder Can be performed quickly and smoothly, making it easy to use. In addition, even if the knob is rotated to some extent, even if it is operated to some extent, the body is not easily detached from the knob, so that the knob can be reliably rotated to quickly wind up and rewind the string. .

  In addition, since the engaging device includes a pick-in / out part and a receiving part for receiving the whole pick that is relatively inserted through the pick-up / removal part, Even if the structure is such that the entire body is supported and the device and the knob are rotated together with respect to the picking in the engaged state, the engaging and disengaging operation can be easily performed by moving the knob in and out. In addition, the receiving part can be received so as to enclose the entire knob, and the body can be securely engaged with the knob, and for example, the container formed larger than the knob can be securely wrapped with almost the whole hand. It can be held and rotated to improve operability.

  In addition, since the receiving part is provided with a bullet gripping part that accepts the knob in a releasable manner and elastically grips the knob in the receiving state, the anchoring device can be realized specifically, and the knob is detached. The operation can be easily performed, the grip is elastically held and the engagement state is maintained well, and the supported operation of the handle and the rotation operation of the handle can be reliably performed.

  In addition, since the bullet gripping portion has a clip piece that is constantly biased in the pinching direction of the knob at the pinch portion that bullets and grips the knob, the pinch piece is opened and closed by the bullet biasing force to pick the body. In addition to being able to easily engage and disengage, it is possible to realize the co-rotation with the support to the knob of the body and the knob at the time of the rotation operation by securely engaging.

  Moreover, since the pinch piece is composed of a pair of pinch pieces arranged to face each other so as to be openable and closable, it is possible to specifically realize the pinch piece that can securely grasp the knob.

  In addition, the operation part of the container includes a clue part for the operator to hold the entire container by hand and to rotate the knob around the rotation axis. Since it can be gripped and operated so that it is almost entirely wrapped, a relatively large force can be applied to the body without imposing a burden on the local parts of the hand and fingers, and the body can be reliably rotated. Good sex.

  Hereinafter, a winder for a string winding device for a stringed instrument according to the present invention will be described with reference to the accompanying drawings. The winder for the string winding device of the stringed instrument of the present invention is detachably attached to the knob of the string winding device, for example, when exchanging or tuning the string of a stringed instrument such as a guitar, and rotates the knob. The string can be wound and rewound. FIG. 1 thru | or 6 has shown one Embodiment of the winder for string winding apparatuses of the stringed musical instrument of this invention. Note that, for example, the same members as those described in the background art such as a string winding device are denoted by the same reference numerals. In the present embodiment, a winder for a stringed wind instrument (hereinafter simply referred to as “winder”) 10 of a stringed musical instrument 10 has a body 12 having an operation unit for rotating the knob 104 of the string winder 100 of the stringed instrument.

That is, in this embodiment, the operation part includes the clue part 20 formed by the entire cylindrical side wall 16c of the container body 12. As shown in FIGS. 5 and 6, since the knob 104 is provided in a flat shape, the direction of the finger grip surface of the knob changes when the knob 104 is rotated around its rotation axis. When doing so, the wrist and fingers may be twisted in an unreasonable direction. On the other hand, as in the present embodiment, the entire body including the clue part 20 is cylindrical, and the entire handle is included in the container, so that the entire body larger than the knob 104 is used as the clue part 20. The operability is good because it can be rotated while being held by almost the whole hand while securing a large moment. At the same time, regardless of the rotation angle around the rotation axis of the knob, the user can always easily put the hand in the same manner, and can easily perform the rotation operation without forcibly twisting the wrist and fingers. In addition, even when engaged with any of the knobs 104 of a large number of string winding devices arranged side by side on the left and right of the head portion H, it can be rotated well and reliably regardless of the location. As shown in FIG. 2, a large number of fine irregularities 22 are formed on the outer surface of the cylinder of the vessel 12 to provide anti-slip means for preventing a finger from slipping during operation. Operation can be performed. In the drawing, the concavo-convex portion 22 is schematically shown by drawing a large number of lines on the cylindrical side wall. The anti-slip means is not limited to the formation of the concavo-convex portion on the cylindrical side wall 16c, and may be formed of a material having a high frictional force such as rubber on the outer surface of the cylindrical side wall 16c. The vessel body 12 is formed to have a large internal space with respect to the knob so that the knob 104 can be included, but the vessel body may be set to a size that does not interfere with the adjacent knob 104. The vessel is not limited to a cylindrical body, and may be any other three-dimensional shape such as an elliptic cylinder, a prism, a three-dimensional shape imitating a natural object, a character, or the like.

  As shown in FIGS. 1 and 3, the engaging device 14 is engaging means for detachably engaging the container 12 to the knob 104. In this embodiment, the engaging device 14 allows the container 12 to be engaged and disengaged with respect to the knob 104, while the entire supported body 12 with respect to the knob 104 in the engaged state, the container 12 and the knob. Includes a structure that allows co-rotation. In other words, the engagement device 14 maintains the engagement state in the state where the container body 12 is engaged with the knob 104 unless the operator performs the detachment operation of the container body 12 with respect to the knob 104. The entire body is supported by the knob 104, and even when the hand is released from the container 12, it can be well prevented that the container is detached from the knob 104 and dropped. Specifically, the anchoring device 14 includes a loading / unloading portion of the knob 104 and a receiving portion for receiving the entire knob 104 inserted relatively through the loading / unloading portion. In the present embodiment, the insertion / extraction part is composed of the insertion opening 18 formed in the first end face wall 16a of the container body 12 described above. The receiving part is provided in the internal space 12a of the container body 12. The knob 104 is inserted into the receiving body internal space 12a through the insertion opening 18 so as to be detachable, and the knob 104 is received in the receiving state. A bullet holding part 24 is provided for bullet holding.

  As shown in FIGS. 1 and 3, in the present embodiment, the bullet gripping portion 24 is built in, for example, the body 12, and a pair of sandwiching pieces 26 that are opposed to each other so as to be openable and closable, A resilient member 28 that constantly urges the pinching piece 26 in the closing direction. That is, in the present embodiment, the pinching piece 26 constitutes a pinching portion that receives and grips the knob 104 so as to be detachable, and the resilient member 28 constantly urges the pinching piece 26 in the pinching direction of the knob 104, The pinching piece 26 and the elastic member 28 cooperate to realize an engaging structure.

  The pinching piece 26 is formed of, for example, a hard synthetic resin such as plastic, and is formed of a rectangular plate member having a thickness approximately equal to the finger-hanging surface of the knob 104 and having a thickness of a few millimeters. It arrange | positions in the space 12a. The pinching piece 26 is arranged so as to be substantially along the insertion direction of the knob 104 inserted from the insertion opening 18 of the container body 12, that is, in the direction of the cylindrical axis or slightly inclined, and accepts the knob 104 having a flat shape on the opposite inner surface. At this time, the pinch means is configured by being brought into contact with the finger-holding surface of the knob 104. The sandwiching piece 26 has a free end on the lower edge side in FIG. 1 facing the rectangular insertion opening 18, and an upper edge side on the upper side in FIG. It is pivotally connected via a pivot 30 such as a hinge so that it can be freely opened and closed. The sandwiching piece 26 has, for example, a wall surface that is erected from the first end face wall 16a to the internal space 12a of the body in the short side direction of the insertion opening 18 and opposed to the sandwiching piece. The elastic member 26 is supported by the supporting member 32 including the elastic member 26. As shown in FIG. 6, each of the pair of sandwich pieces 26 is a movable piece and is urged in the closing direction. A tapered portion 26 a that is inclined toward the inner side in the insertion direction of the knob 104 is formed on the edge side of the sandwiching piece 26 facing the insertion opening 18. When the knob 104 is inserted from the insertion opening 18, the knob 104 is guided to the tapered portion 26 a and reliably guided between the sandwiching pieces 26. The elastic members 26 are made of, for example, coil springs, and three elastic members 26 are interposed between the opposing portions of the support member 32 and the pinching piece 26 to support the pinching piece 26 and bias it in the closing direction. . As shown in FIG. 6, when the knob 104 is inserted from the insertion opening 18, the insertion tip end side of the knob hits the taper portion 26 a of the clip piece, and when further pressed, the clip piece resists the biasing force of the elastic member 26. 26 opens and accepts the pick in the meantime. In the state of being received between the pinching pieces 26, the elastic member 28 is always urged in the pinching direction of the knob, so that the container 12 can be easily prevented from detaching from the knob and the knob can support the entire apparatus body. Can be realized. In other words, in this embodiment, the operator can easily engage the container body 12 by pressing it into the knob 104 in a crimping manner. On the other hand, the operator can easily remove the container 12 from the knob only by pulling out the container from the knob 104. Therefore, even in a configuration having a structure in which the instrument body is supported and operated together with the knob in the engaged state, the engagement / disengagement operation of the instrument body can be performed very easily, which is easy to use.

  In addition, in FIG. 7, the other form of the anchoring apparatus 14 is shown. As shown in FIG. 7, for example, the configuration of the bullet gripping portion 24 is different, and as a bullet member for biasing the pinching piece 26 in the pinching direction of the knob, from the outside of the pair of pinching pieces 26 arranged to face each other. It includes an endless elastic member or rubber band 34 that is hung and urges each other in the closing direction. In FIG. 7, a coil spring 36 that supports the pinching piece 26 on the support member 32 is also provided as a resilient member, and the rubber band 34 and the coil spring 36 cooperate to urge the pinching piece 26. Yes. As shown in the figure, a concave portion 38 is formed on the outer side opposite to the pinching piece 26, and the rubber band 34 is locked to the concave portion 38 in a state where the pinching piece 26 is housed in the inner hole portion of the rubber band 34. , Prevents the rubber band from being displaced or detached. A protrusion may be provided instead of the recess to prevent the rubber band from being displaced or detached. In the above-described embodiment shown in FIG. 1 to FIG. 7, the pair of sandwiching pieces 26 are both configured as movable pieces, but for example, a fixed piece in which one sandwiching piece is fixed inside the body. The other sandwich piece may be a movable piece that opens and closes with respect to the fixed piece. Further, in FIGS. 1 and 7, the pinching piece 26 is formed with a substantially triangular gap in the closed state where the knob 104 is not pinched, but the opposing surfaces are in close contact with each other. It may be configured. Further, the pinching pieces 26 are connected to each other by the pivotal support portion 30 so as to be opened and closed. For example, the pinching pieces may be opened and closed so as to be slidable in the approaching / separating direction. The elastic member 26 is not limited to a coil spring, and may be a biasing member such as a leaf spring or other elastic body such as rubber. Moreover, you may support the elastic member 28 directly in the inside of the cylinder which comprises a container, for example. Further, for example, a spring member that urges the pinching piece 26 in the closing direction may be formed on the pivotal support portion 30 itself. The bullet gripping portion 24 may be configured to open and close so that the pinch piece 26 is formed of a resilient material, and the pinch piece is biased in the pinch pinching direction, for example. For example, the pinching piece 26 may be formed of a relatively hard rubber or resin material having a certain degree of elasticity and fixedly arranged inside the container.

  When the winder 10 according to the present embodiment is used, as shown in FIG. 5, the clasp portion 20 of the body 12 is grasped by the hand, and the direction of the rectangular insertion opening 18 is set to the string winding device 100 of the stringed instrument. In a state in which the knob 104 is aligned with the direction of the knob 104, the container body 12 is pressed in a crimping manner toward the head portion side, and the knob 104 is inserted into the inner space of the container body from the insertion opening 18. At that time, the knob 104 is guided by the taper portion 26a of the pinching piece 26 in accordance with the pressing operation in the crimping direction toward the head portion H side of the entire body, and then pinched against the urging force of the elastic member 28. The pieces 26 are pushed outward and inserted between the sandwich pieces 26. As shown in FIG. 6, in a state where the knob is received between the pinching pieces 26, the pinching piece is always urged in the pinching direction of the knob by the elastic member 28, whereby the body is engaged with the knob. In this engaged state, the engaged state is maintained with respect to the knob 104 by the biased clip piece 26, and the entire body is supported by the knob 104. Then, when the entire body is grasped by the hand via the clue part 20 and rotated around the axis, the body and the knob rotate together in the state where the knob is engaged by the pinch piece, and the knob is rotated with the rotation axis (X ) It can be turned around, and the winding shaft 102 can be turned to perform winding or rewinding of the string. As a result, the operator can easily engage the container 12 by pushing it into the knob 104 in a pressure contact manner. Furthermore, since the entire body is supported by the knob 104, both hands can be used freely with the body attached to the knob. Thus, for example, when a new string is stretched, the body 14 can be attached to the knob 104 when the hitch work is performed prior to the string winding work. Smooth transition to work and quick winding of strings. In addition, while maintaining the engaged state, it is difficult to easily come off the knob 104, and the body contains the entire knob so that it can be rotated while being gripped so that the clasp portion is covered by almost the entire hand. Since the structure can secure a relatively large moment, the operability is good and the knob can be reliably rotated even by a quick and rough rotation operation to some extent. After the winding and unwinding operation of the string by the winder 10, the operator can easily remove the container 12 from the knob by simply grasping the entire body by hand and pulling it out. In the same manner, it is engaged with another string winding device to wind up and perform a rewinding rotation operation.
