Abstract: A strainer device for a drum includes a fixing portion attachable to a shell of the drum, an operation portion, a movable portion moved with respect to the fixing portion to change a snare wire between an ON state and an OFF state, a pressing member, a cam portion including a cam surface, and a follower configured to be relatively displaced with respect to the cam portion between a first position and a second position in the cam portion while the pressing member is pressing against the cam surface. A direction of a force acting on the follower with respect to the cam portion is directed to: a side of the first position within the cam portion in a state where the follower is disposed in the first position, and a side of the second position in a state where the follower is disposed in the second position.

Abstract: A snare strainer adapted to a snare drum comprises first and second strainers, which are attached to opposite positions on the exterior circumferential surface of a drum cylinder and by which a snappy member including snares is controlled to move in close contact with or separate from the backside drumhead upon operation of a switch mechanism. One end of an interconnection member included in the snappy member is held between first and second holding members of the first strainer, and the other end is held between third and fourth holding members of the second strainer. A tension adjustment screw is operated to adjust tension applied to the snappy member, which can be visually observed using the scale. Hence, it is easy for the human operator to attach and replace the snappy member and to replace the backside drumhead with another drumhead in a short period of time.

Abstract: In a drumhead stretching mechanism adapted to a drum, a bolt for tightening or loosening a drumhead stretched at ends of a hollow cylinder under tension is inserted into a latch that is hooked on a clamp frame for clamping and holding outer circumferential ends of the drumhead, wherein a hollow space is formed inside of the latch to store an anti-extraction member having a U-shape, which is engaged with the bolt. Alternatively, the latch and anti-extraction member can be integrally interconnected together. Thus, it is possible to reliably prevent the bolt from being extracted, from unnecessarily rotating, and from floating in the axial direction of the bolt even when the bolt is taken out from a lug nut, which normally engages with the tip end portion of the bolt.

Abstract: This invention is adapted to a snare drum having a snare that is stretched under tension above a snare head, wherein both ends of the snare is protected by snare gates, which are fixed to prescribed positions opposite to each other across the snare head stretched under tension across an opening of a hollow cylinder. Each of the snare gates is constituted by a slender horizontal plate, and a pair of legs fixed to a hoop that is fixed to circumferential ends of the opening of the hollow cylinder, wherein it is reinforced by ribs that are formed by inwardly bending side edges of the legs so that the ribs are formed integrally together with the legs. Thus, it is possible to increase the overall strength of the snare gate by using ribs without increasing the thickness of a material plate used therefore.

Abstract: A musical instrument stand such as a hi-hat stand is basically constructed by a pair of cymbals, a stand member, a foldable tripod containing three legs, a pedal frame, an operation rod, a return spring, a transmission member, a pedal, a heel and an interconnection member. Normally, the return spring applies resilience to the operation rod, a lower end of which is being pressed upwardly together with a front end of the pedal by means of the transmission member. In addition, the interconnection member is formed in a U-shape, in which a bent portion is fixed to the heel of the pedal while ends are detachably attached to feet of the pedal frame. For storage and transportation of the musical instrument stand, the ends of the interconnection member being elastically deformed are disconnected from the feet of the pedal frame. Herein, straight portions of the interconnection member are held by holders, which are U-shape channels projecting downwardly from a back surface of the pedal.

Abstract: A high-hat stand has a telescopic guide tube supported by a pedestal, a pedal mechanism connected to a movable rod inserted in the telescopic guide tube and a generally U-letter shaped connector for connection, a heel of the pedal mechanism to the pedestal, wherein the generally U-letter shaped connector has a certain modulus of section so as to keep the clasticity thereof against a maximum bending moment exerted thereon during a performance so that the high-hat stand is simple in structure without sacrifice of the stability.

Abstract: A musical instrument stand such as a hi-hat stand equipped with hi-hat cymbals is basically constructed by legs (or tripod), a stand member, a pedal frame, an operation rod and a return spring. Herein, the operation rod is inserted into an internal space of the stand member, which is a pipe being vertically supported by the legs, such that the operation rod is capable of moving up and down inside of the stand member. The pedal frame is placed horizontally in connection with the stand member and is equipped with a pedal having a prescribed angle against a horizontal plane. The operation rod is normally pressed upwardly by the return spring by means of a connection member. When a performer depresses a front end of the pedal with his or her foot, the operation rod which is interlocked with the pedal by means of a transmission member is forced to move downwardly against spring force of the return spring.
