Description

  The present invention relates to a drop-type clutch for a hi-hat upper cymbal.

  An outline of a typical embodiment of a conventional drop clutch will be described. A side view of an example thereof is shown in FIG. The configuration is roughly divided into two parts based on the clutch head (3) and the clutch bolt (5). A hook (4) and a wing bolt (2) are attached to the clutch head (3). The clutch head (3) has a cylindrical body (3A) with a central axis that has a hole that is slightly larger than the diameter of the rod (1), and a screw hole that passes through the hole in a direction perpendicular to the surface. Yes. After the rod (1) is passed through the central axis of the clutch head (3), the wing bolt (2) is screwed into the screw hole to fix the clutch head (3) to the rod (1). Further, the surface of the clutch head (3) has a protrusion (3B) in a direction perpendicular to the central axis, and a hook (4) and a spring (12) are attached thereto. Due to the elastic force of the spring (12), a force is always applied to the hook (4) so as to rotate in the direction in which the hook protrusion (4B) protrudes.

  The clutch bolt (5) is a hollow bolt having a hole of a size that allows the rod (1) to pass through without friction, and a stopper nut (15) having a conical inclined surface from above, and a pair of upper and lower A lock nut (8) is screwed, and a pair of upper and lower felt washers (9) and an upper cymbal (10) are secured with a bottom nut (11) located at the bottom of the lock nut (8B) and clutch bolt (5). Hold and hold them. The stopper nut (15) is located at a position where the distance from the lowermost surface to the uppermost surface of the clutch bolt (5) is equal to the distance from the hook protrusion (4B) to the lowermost surface of the clutch head cylindrical body (3A). When the hook (4) is caught by the stopper nut (15), the clutch bolt (5) cannot be moved slightly in the direction of its central axis.

  With the clutch head (3) and clutch bolt (5) as described above passed through the rod (1) and the hook (4) hooked onto the stopper nut (15), the upper cymbal (10) and the lower cymbal (13 ), The wing bolt (2) is pressed and fixed to the rod (1) so that the upper cymbal (10) does not fall at a position where an appropriate gap is opened. In this state, the hi-hat can be played. When the hook lever (4A) is hit with a stick or the like during performance, the hook (4) is released from the stopper nut (15). At that moment, the clutch bolt (5) integrated with the upper cymbal (10) starts free-falling with the rod (1) as a rail, and the outer periphery of the upper cymbal (10) is the outer periphery of the lower cymbal (13). Will continue to rest after collision. At this time, if the cymbal is hit, the vibration of the cymbal is extinguished by the weight of the upper cymbal (10), and the reverberation disappears. This state is called a closed state because the state between the upper cymbal (10) and the lower cymbal (13) is closed. Further, as shown in FIG. 4, when the hi-hat stand pedal (14) is depressed, the rod (1) is pulled downward, so that the clutch head (3) fixed to the rod (1) also moves downward. When the clutch head (3) is stepped to the point where it touches the upper end of the clutch bolt (5), the hook (4) is again hooked to the stopper nut (15). (10) rises and keeps the hi-hat open. The conventional drop clutch enables the hi-hat to be easily switched between the open and closed states by the mechanism as described above, and its purpose is to obtain a closed tone during performance.

  This has the following drawbacks. In the first place, the drop-type clutch is used by drum players who use a performance method called a two-bass playing method. The two-bass playing method is a playing method in which another pedal is operated with the foot placed on the hi-hat stand pedal (14). In this case, the hi-hat is inevitably opened, but when the hi-hat is hit in this state, the upper cymbal ( The sound attenuation of 10) is too slow and the hi-hat does not play a musical role.

  Therefore, if a conventional drop clutch is used, a closed state sound can be obtained, but during the two-bass playing, in addition to the closed state sound, a slight contact between the upper cymbal (10) and the lower cymbal (13) is suitable. A half-open sound with reverberation is often preferred and used, and it is possible for a drummer to perform more musically if individual drums can select sounds from closed to open. However, the conventional drop-type clutch can only produce a sound with no reverberation in the closed state, leading to a restriction on the range of musical expression. An object of the present invention is to provide a drop-type hi-hat clutch that eliminates the above-described drawbacks and can be in not only a closed state but also an arbitrary half-open state.

  A stopper nut (7) having a thickness smaller than that of the conventional stopper nut (15) is prepared. This stopper nut (7) does not necessarily require a conical inclined surface. This is screwed to the clutch bolt (5), and a pair of upper and lower lock nuts (6) are added and screwed to the upper part thereof. At this time, the stopper nut (7) is fixed at a position where the screw bolt of the clutch bolt (5) is secured from the upper surface of the clutch bolt (5) on the upper and lower sides of the lock nut (6). Is good. Also, the lock nut (6) is preferably the same in diameter as the stopper nut (7) or slightly larger than that. Instead of the pair of upper and lower lock nuts (6), a nut having a screw hole penetrating from the side surface toward the inner space and a bolt that can be screwed into the screw hole may be used. The advantage of using the lock nut (6) is that the upper and lower lock nuts (6A, 6B) are tightened so that the upper and lower lock nuts (6A, 6B) approach each other at an arbitrary position of the clutch bolt (5) above the stopper nut (7). A force is applied in the direction, which causes friction between the thread groove of the lock nut (6) and the thread groove of the clutch bolt (5), and can be easily fixed as a result.

  When the hook lever (4A) is hit with the hook (4) hooked on the stopper nut (7), the hook (4) is separated from the stopper nut (7), and the clutch bolt (5) starts dropping at that moment. However, because the spring (12) is elastic between the clutch head protrusion (3B) and the hook (4), the hook (4) is applied with a force that rotates in the direction of the hook protrusion (4B). 4) comes into contact with the side surface of the clutch bolt (5), and as a result, the hook (4) is caught on the lower surface of the lower lock nut (6B). This makes it possible to adjust the drop distance of the clutch bolt (5) necessary for achieving the object of the present invention.

  Since the upper cymbal (10) can be dropped to any height from the open state to the closed state, it is possible to create a half-open state that suits individual preference. If it is desired to be in the closed state, it can be adjusted as such, and the upper cymbal (10) can be further dropped from the half-open state, and the timbres in two states can be obtained by making the closed state. . This means that the present invention incorporates the function of a conventional drop clutch. Further, regarding the adjustment of the degree of opening, the adjustment can be completed easily in a short time because the lock nut (6) is simply turned and moved in the vertical direction.

It is a side view which shows the practical example of this invention. It is a perspective view of a clutch head part. It is a disassembled perspective view of a clutch bolt part. It is a perspective view of a hi-hat stand. It is a side view of the conventional drop type clutch.

  A side view of an embodiment of the present invention is shown in FIG. As shown in FIG. 2, the clutch head (3) includes a cylindrical body (3A) in which a hole slightly larger than the diameter of the rod passes through the central axis of the cylinder, and a screw that penetrates in a direction perpendicular to the central axis from the surface to the inner space. A hole, a wing bolt (2) that can be screwed into it, a hook (4) fixed at one point to a protrusion (3B) on the side of the cylinder (3A) so that it can rotate, a hook (4) and a cylinder It is comprised from the spring (12) installed in the clutch head protrusion part (3B) so that a repulsive force may be added during (3A).

  As shown in FIG. 3, the clutch bolt (5) is a bolt having a thread groove on the entire periphery through which a hole slightly larger than the diameter of the rod (1) passes, and a pair of upper and lower lock nuts (6 ), A stopper nut (7), a pair of upper and lower lock nuts (8), and a bottom nut (11) are screwed onto the clutch bolt (5) in this order from above. Regarding the diameter of the nut, the upper lock nut (6) should be the same as or larger than the stopper nut (7). Instead of the upper lock nut (6), a nut having a screw hole penetrating from the side surface toward the inner space and a bolt that can be screwed into the screw hole may be used. The stopper nut (7) is fixed so as not to rotate thereafter at a position where the upper surface of the clutch bolt (5) and the lower surface of the clutch head cylindrical body (3A) are in close contact with the hook (4) hooked on the lower surface. The stopper nut (7) may be fixed by using an adhesive, or a nut comprising a thread groove penetrating from the nut surface to the inner space and a bolt that can be screwed into the groove. At this time, it is necessary to determine the fixing position of the hook (4) accordingly so that a space that allows the lock nut (6) to move appropriately both upward and downward can be secured. The upper cymbal (10) is sandwiched between a pair of upper and lower felt washers (9) and is passed between the lock nut (8) and the bottom nut (11).

  The clutch head (3) and the clutch bolt (5) constituted by the above parts are inserted into the rod (1) from above in this order. At this time, with the hook (4) hooked on the stopper nut (7), the wing nut (2) is tightened at a position where there is an appropriate gap between the upper cymbal (10) and the lower cymbal (13). As for the position of the lock nut (6), when the hook (4) is hooked on the lock nut (6B), the upper and lower lock nuts (6A, 6A, What is necessary is just to clamp | tighten and fix in the direction which 6B) approaches.

  As an example of use, the hook (4) is detached from the stopper nut (7) by hitting the hook lever (4A) while the hook (4) is caught by the stopper nut (7). The clutch bolt (5) provided with 10) starts to fall, and the hook (4) restored to its original position automatically by the elastic force of the spring (12) is caught on the lower surface of the lock nut (6B), and the upper cymbal ( This is used to instantly narrow the gap between 10) and the lower cymbal (13). If the upper cymbal (10) is then restored to its original position, as shown in FIG. 4, the rod (1) is moved downward by stepping on the hi-hat stand pedal (14), and the hook (4) is used as a stopper. After being caught on the bottom surface of the stopper nut (7) again along the outer surface of the nut (7), the step is released to complete.

  Regarding the shape of the component parts of the present invention, the clutch bolt (5), the lock nut (6), and the stopper nut (7) may be circular, but the other parts do not impair the above functions. If so, the shape is not limited.
