The end pin A can be held between the distal end surface of the screw shaft 4 and the distal end side inner surface of the hook portion 7.

According to this embodiment, when assembling the weight 1 for a stringed instrument, the screw hole 3 provided near the center of the bottom of the weight body parts 2A, 2B, which are made up of a plurality of independent weights, is aligned with the screw shaft 4. By rotating the weight body parts 2A, 2B with respect to the screw shaft 4, the screw hole 3 and the base end of the screw shaft 4 can be engaged and screwed into each other. The tip of the screw shaft 4 is left extending from the tip side of the weight body portion 2A. As shown in FIG. 2, the weight body portions 2A and 2B may be weights having different weights, or may be composed of weights having the same weight. The cross-sectional shape of the weight body portion 2 may be rectangular, circular, or elliptical, and is not limited in any way.

Even when using a plurality of weight body parts 2 like the weight body parts 2A and 2B, since each screw hole 3 is formed with the same diameter, the number and combination of the plurality of weight body parts 2 to be attached can be changed. It is possible to set the optimum weight by changing the

Next, a hook portion 7 is attached to the tip portion 6 of the screw shaft 4 extending from the weight body portion 2. The hook portion 7 has a U-shaped hook portion 7 cut out from the side. As shown in FIG. 3, the hook part 7 includes a pair of opposing parts, a distal facing part 8 and a proximal facing part 9, which are spaced apart from each other in the axial direction of the screw shaft 4, and a distal facing part 8. and a connecting part 10 connecting one side end of the proximal facing part 9, and a latching space surrounded by the distal facing part 8, the proximal facing part 9, and the connecting part 10. It has. It is preferable that the distal end facing portion 8, the proximal facing portion 9, and the connecting portion 10 are integrally formed. By being integrally formed, it is possible to reduce the loss of the amplification effect of the sound of the musical instrument. Note that the distal end facing portion 8, the proximal facing portion 9, and the connecting portion 10 may be formed separately. At this time, other connecting means such as a spring may be used for the connecting portion 10.

Near the center of the proximal facing portion 9 of the hook portion 7, a through screw hole 12 is provided from the proximal end toward the distal end. By rotating the weight body portion 2 with respect to the screw shaft 4, the through screw hole 12 of the hook portion 7 and the tip end portion 6 of the screw shaft 4 can be engaged and screwed. Preferably, a rotation prevention portion 5 is provided near the axial center of the screw shaft 4. The rotation prevention portion 5 may be provided with a smooth surface without threads near the axial center of the screw shaft 4, or may be a portion with a larger diameter than the threaded portion. By providing the rotation prevention means, the weight body portion 2 can be stopped at a predetermined position.

Next, the weight 1 for a stringed instrument in which the hook portion 7 and the weight body portion 2 are connected by the screw shaft 4 is attached to the end pin A. At this time, it is preferable that the end pin A extends from the bottom of the side surface of the stringed instrument B and is adjusted in advance to a length desired by the user.

The user places stringed instrument B on his lap while sitting on a chair, tilts stringed instrument B so that endpin A is approximately parallel to the floor, and attaches stringed instrument weight 1 to endpin A. . At the time of attachment, the inner surface of the distal end facing portion 8 of the hook portion 7 is brought into contact with the outer circumferential surface of the end pin A and hung. At this time, the inner surface of the distal end side of the hook portion 7 has a recess 11 at the center of the inner surface in the distal direction. As a result, when the stringed instrument weight 1 is hung on the end pin A, even if you release your hand and the stringed instrument weight 1 swings, the end pin A will be hung on the recess 11 at the center of the inner surface, as shown in FIG. Therefore, there is no need to worry about the stringed instrument weight 1 slipping off the end pin A.

Next, the stringed instrument weight 1 is fixed to the end pin A. As shown in FIG. 3, the weight body 2 is rotated about the screw shaft 4 while being held by hand. When the weight body portion 2 and the screw shaft 4 rotate together, the tip of the screw shaft 4 enters the latching space, and further advances toward the tip side opposing portion 8, as shown in FIG. The outer circumferential surface of the end pin A is held between the inner surface of the distal end facing portion 8 and the distal end surface of the screw shaft 4. Thereby, the stringed instrument weight 1 is fixed to the end pin A.

The procedure for removing the weight 1 for a stringed instrument from the end pin A can be carried out by holding the weight body 2 and rotating the axis in the opposite direction to release the end pin A from the clamped state by the screw shaft 4.

The weight body portion 22 is preferably a weight lighter than the weight body portion 21 so that the weight can be adjusted according to the user's wishes.

FIG. 9 shows a stringed instrument B in which the stringed instrument weight 1 is attached to the end pin A. The end pin A protrudes further downward from the lower end of the stringed instrument B, and is located far from the player's hand. However, if the weight 1 for a stringed instrument according to the present invention is used, the end pin A can be used as shown in FIGS. 3 and 4 and the explanation thereof. Through the attachment work, even while supporting the stringed instrument B with one hand, it becomes possible to attach the stringed instrument weight 1 to the end pin A using only the other hand. As shown in FIG. 9, by attaching the stringed instrument weight 1 to the end pin A, the resonance of the sound produced by the stringed instrument B can be improved.

In addition, if the stringed instrument B is a large instrument such as a contrabass, it is necessary to tilt the instrument with the end pin A pushed up on the floor and hang the hook part 7 on the end pin A, and also to hang the hook part 7 on the end pin A. By performing the work of fixing the weight 1 to the end pin A in a series, it is possible to complete the work of attaching the weight 1 for a stringed instrument using only the other hand without removing one hand from the stringed instrument B.
