A tightening structure of a musical instrument stand includes stationary or immovable member and a movable member. The movable member includes a cylindrical shaft extending outward in an axial direction. One side of the immovable member has a recess. A bottom of the recess forms a semi-circular arc with a radius of curvature corresponding to that of the shaft. When the shaft is inserted into the recess it abuts against the bottom of the recess. The immovable member has a screw hole communicating with the recess. The screw hole is perpendicular to the axial direction of the cylindrical shaft. A fastening bolt is screwed into the screw hole. One end of the first fastening bolt is inserted into the recess and has a flared end portion to press against the shaft, and another end is connected with a handle. By rotating the handle, the flared end portion is drawn against the shaft, thereby rendering the movable member stationary.

A slide and glide drum mount system has a first coupling that is configured for removable, fixed attachment to a support post. The first coupling has a stub extending outwardly from a surface of the first coupling. A second coupling that is configured for removable, fixed attachment to a drum. The second coupling having a hole through a surface of the second coupling. The first coupling and the second coupling are removably and slidably connected with the stub disposed in the hole and with the surface of the first coupling and the surface of the second coupling engaged in contact, thereby mounting the drum to support post.

A bass drum spur system has a pivot assembly and a spur leg assembly. The pivot assembly has a spur hub removably attachable to a rim of a drum and a hub cover attached to the spur hub. The hub cover has a passageway and a circumferential slot formed through a sidewall of the passageway. The circumferential slot has first and second notches at respective opposite ends of the slot. A release button is axially slidable within the passageway of the hub cover and a spring is disposed in the passageway and biases the release button in a direction away from the spur hub. The spur leg assembly has a post fixedly attached to the release button for movement therewith, wherein the post is movable between engagement with the first notch and the second notch by pressing the release button in a direction toward the spur hub and rotating the post along the circumferential slot.

A portable musical instrument blocking device (1) to limit unwanted movement of a musical instrument during use. The blocking device engages said musical instrument's forward-facing leading edge where kinetic energy of the musical instrument's forward motion is transferred to the main body (2). A gripping material (10) on the blocking device's downward-facing surface grips the floor surface (9) and thereby limits movement on the floor plane. Engagement between the blocking device and the musical instrument is such that kinetic energy of the musical instrument's upward motion is not substantially transferred to the blocking device. The blocking device can be easily detached from the floor surface with application of manual force in the upward direction.

A compact drum kit is provided. The drum kit has a body having a hollow interior cavity and a sound hole for transmitting sound wave from the interior cavity to exterior of the body, the body has a striking head and an opposing resonant head. The drum kit has a top plat attaching to a top side of the body and a platform attaching to a bottom side of the body. The drum kit has a shaft mounting bracket attaching to the top plat and a pivot shaft mounting bracket attaching to the top plat. A plurality of upward extending component mounting shafts are supported by one of the shaft mounting bracket and the pivot shaft mounting bracket. One or more percussion modules that attach to one or more of the plurality of component mounting shafts, wherein each percussion module produces a sound in response to being struck or scraped. A drum kick assembly is positioned on the striking head side of the body and including a beater positioned to strike the striking head of the body to produce a sound. A hi-hat pedal assembly is positioned on the resonant head side of the body.

The hi-hat attachment includes an upper unit, a lower unit, and an operation lever. The lower unit includes a regulation unit that regulates the maximum fall position of the lower unit. The regulation unit is configured to adjust the maximum fall position of the lower unit.

By rotating the handle, the flared end portion is drawn against the shaft, thereby rendering the movable member stationary.

The invention comprises a first fixture group for clamping a first erecting rod, a second fixture group for clamping a second erecting rod, a fixed bolt and a compression spring, wherein the first fixture group comprises a first cylindrical portion with a first non-circular axisymmetric profile, the second fixture group comprises a second cylindrical portion sleeved with the first cylindrical portion, the second cylindrical portion comprises a second non-circular axisymmetric profile correspondingly sleeved with the first non-circular axisymmetric profile, and the first cylindrical portion axially slides relative to the second cylindrical portion to have a rotatable rotating position and a non-rotatable clamping position, the fixed bolt penetrates through the second cylindrical portion, the first cylindrical portion and the compression spring to be screwed with a nut, and the first cylindrical portion is pushed by the compression spring to move from the rotating position to the clamping position.

A drum stand coupler is provided, including: a fixing mechanism and a connecting mechanism. The fixing mechanism is configured to be disposed on a drum body. The connecting mechanism is rotatably connected with the fixing mechanism and configured to be assembled with a stand. A drum using the drum stand coupler as described above is further provided, further including: the drum body. An interconnection of the fixing mechanism and the connecting mechanism defines a rotating axis about which the connecting mechanism is rotatable, and the rotating axis is transverse to an axial direction of the drum body.

The invention relates to a drum and to a device (1) therefor, having a system (3) for altering the attack and decay behavior, in particular the note length of the drum (2). The aim of the invention is to provide a device for a drum and a drum having such a device, which can alter the attack and decay behavior quickly and with little effort, and in particular enables setting of the note length and also of the timbre of the drum largely independently of the pitch. This aim is achieved in that the system (3) is fastened to the drum (100, 2) and has a clip (5) on which an adjustable connecting element (6) is arranged, which is designed for a connection to a support arm or to a base support (7).
