[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a snare strainer for allowing a snappy (sound line) normally provided on the back side of a snare drum to contact and separate from the drum head surface.

[0002]

2. Description of the Related Art FIG. 4 is a perspective view of a general snare drum (small drum) 1 viewed from the back side. Generally, as shown by reference numeral 3 on the back side of the snare drum, the snare drum abuts against the back side drum head 2 and vibrates with the vibration of the back side drum head 2 to generate a light sound that is jarred. ). This snappy 3
Is composed of a plurality of bowel strings or coil-shaped metal strings (snappy wires) stretched in the diameter direction of the drum head 2. As shown in FIG. 4, the snappy 3 has snare trainers 5 and 5 (only one of which is shown) having both ends attached to the body 4 of the snare drum 1.
Each is fixed. In addition, at least one of the snare trainers 5 and 5
A mechanism is provided to make the snappy 3 detachable from the back drum head 2 (contact and separation), and the mechanism can be switched by a lever 6.

[0005] In FIG. 5, reference numeral 7 denotes a base plate forming the essence of the snare strainer 5, which is fixed to the body 4 of the snare drum 1 by screws 8, 8. The base plate 8 is provided with a slide plate 9 slidable in the vertical direction. A snappy fixing plate 11 that is opened and closed by screws 10 is provided below the slide plate 9. The end of the snappy 3 is fixed by the snappy fixing plate 11. The base plate 7 is provided with the lever 6 that rotates about a fixed shaft 12. As shown in FIG. 7, a link shaft 14 is provided at a predetermined position in the longitudinal direction of the lever 6, and one end of a link member 15 is rotatably provided on the link shaft 14. As shown in FIG. 5, the other end of the link member 15 is rotatably attached to a distal end portion 17 of an adjustment shaft 16 that supports an adjustment bolt described later. Adjustment shaft 16
Are provided through the base plate 7 and can be moved up and down by being guided by guide grooves 18 formed in the base plate 7. Adjustment axis 1
An adjustment bolt 20 is inserted through 6. Adjustment bolt 2
0 forms a step portion 20a by being reduced in diameter in the middle of the longitudinal direction, and this step portion 20a
6 is in contact with the upper surface. And this adjusting bolt 20
Are screwed onto the upper portion of the slide plate 9. Between the adjustment shaft 16 and the slide plate 9, a spring 21 that constantly urges the slide plate 9 downward is provided outside the adjustment bolt 20. When the lever 6 is rotated clockwise from the state shown in FIG. 7 as shown in FIG. 8 based on the above configuration, the adjustment shaft 16 is lowered by the action of the link mechanism. As a result, the slide plate 9 moves downward, so that the snappy 3 is loosened and separated from the drum head 2. The slide plate 9 can also be moved up and down by operating the adjustment bolt 20, and when adjusting the tension of the snappy 3, the adjustment can be performed by the adjustment bolt 20.

[0004]

The conventional snare strainer 5 has the following disadvantages. That is, the link mechanism described above is used in FIGS.
When the snapper 3 is set, when the lever 6 is operated counterclockwise as shown in FIG.
8 gradually moves upward from the state shown in FIG. 8 to reach the top dead center, and then the link shaft 14 is located to the left of the adjustment shaft tip 17 so that the adjustment shaft 16 is moved to the top dead center. It is slightly lower than the position and enters the locked state.

However, since the above link mechanism is locked at a point slightly above the top dead center as described above,
The lock may be released by a slight external force.

As a means for solving the above-mentioned adverse effects, it is conceivable to set the lock point farther to the left than that shown in FIG. 7 (that is, to set the lock point sufficiently past the top dead center). However, in that case, the return amount of the adjustment shaft 16 after passing through the top dead center becomes large, so that a predetermined tension is not obtained in the snappy 3 or the tension applied to the snappy 3 at the top dead center becomes large, There is a problem that a large force is required for the operation and that the snappy 3 has a bad influence.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a snare strainer in which the lock of the lever 6 is not inadvertently released due to an unexpected external force and the operational feeling is excellent. And

[0008]

SUMMARY OF THE INVENTION According to the present invention, there is provided a snare trainer which supports a snapper of a snare drum and performs an operation of attaching and detaching the snapper via a link mechanism by lever operation. An urging member is provided so as to be opposed to the member, and applies an urging force in a predetermined direction to the link member near the top dead center position of the link member.

[0009]

In the snare trainer according to the present invention, when the lever is operated to set the snapper to the drum head, and when the link member is locked by passing through the top dead center, the link member is connected to the link member. A force for maintaining the locked state is exerted by the urging member.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. 1 to 3 show a snare strainer according to the present invention. In these drawings, the same components as those shown in FIGS. 5 to 8 are denoted by the same reference numerals, and the description thereof will be simplified.

As shown in FIGS. 1 and 2, the outline of the structure of the snare strainer 25 according to the present embodiment is the same as that of the snare strainer 5 shown and described in FIG.

As shown in FIG. 1, rubber (biasing member) is provided above the base plate 7 of the snare strainer 25.
26 is attached so that the base plate 7 may be involved. In this case, the rubber 26 uses a so-called rubber tube formed in a tubular shape. This rubber 26
Is attached to one end of the link member 15, that is, a position close to the end of the link member 15 where the adjustment shaft 16 is provided. More specifically, as shown in FIG. 3, when the lever 6 is in the locked state, the lower end of the rubber 26 is slightly lower than the upper end of the link member 15, that is, the upper end of the link member 15 slightly bites into the rubber 26. It is.

The snare strainer 25 according to the above embodiment.
According to this, when the lever 6 is operated to change the snappy 3 from the separated state to the drum head 2 to the contact state, the upper end of the link member 15 contacts the lower surface of the rubber 26 just before the top dead center. When the lever 6 is further rotated counterclockwise against the elasticity of the rubber 26, the upper end of the link member 15 passes through the top dead center, and is in a locked state as shown in FIG.

In the above state, since the upper end of the link member 15 slightly bites into the lower surface of the rubber 26 as described above, the link member 15 receives the urging force due to the elasticity of the rubber 26. In order to release the lever 6 in such a state, the upper end of the link member 15 needs to elastically deform the rubber 26 again. Therefore, the lever 6 is not unlocked by a slight unexpected external force unless a clockwise force is intentionally applied.
The link member 15 in which the lever 6 is locked.
Is a position slightly passing through the top dead center passage position as in the conventional snare trainer 5 as shown in FIG. 7, so that the snappy 3 does not loosen in this locked state. The link member 15 is in contact with the rubber 26, and the lever 6 is
6, no noise is generated by the contact between the link member 15 or the lever 6 and the base plate 7 during locking.

In the above embodiment, the rubber 26 is used as a means for applying a biasing force for maintaining the locked state to the link mechanism when the lever 6 is locked. Other configurations may be used as long as they exhibit the same function, and for example, a configuration using a combination of a resin ball and a coil spring, or an elastic member such as a coil spring or a plate spring may be used.

[0016]

As described above, according to the snare strainer according to the present invention, when the lever is locked, the urging member exerts an operating force on the link mechanism of the lever to maintain the locked state. It is possible to reliably prevent the lock of the lever from being accidentally released due to an unexpected external force.
