  • Patent number: 11335307
    Abstract: A percussion instrument mount includes a base that supports a percussion instrument in a playing position. The percussion instrument mount also includes a swing arm that is coupled to the percussion instrument, and is also coupled to the base via a joint such that the swing arm rotates about the joint from an equilibrium position in response to a playing impact on the percussion instrument. The percussion instrument mount still further includes a playing impact energy absorber that provides a restoring force to the swing arm so as to return the swing arm to the equilibrium position.

  • Patent number: 10945057
    Abstract: Improvements in a motorized microphone rail system for a musical instrument and more particularly for a percussion instrument such as a drum, marimba or similar musical instrument. The microphone system includes a vibration isolation system. A vertical or horizontal tracking system bridges across supports of a drum or marimba in a vertical or horizontal tracking system. One or more microphones are supported on the first bridging structure. The microphone(s) are positional with a drive screw that is powered by a motor. The microphone can be moved along the supporting rail to alter the sound based upon the phasing of the sound wave between the drum heads or the sound producing elements. Electronic drive and control for operating a motor that positions the microphone is also disclosed.

  • Patent number: 10943572
    Abstract: A shoulder supported carrier structure supports percussion instruments on shoulder shoulders of a user is disclosed. A connecting member that spans between the shoulder supporting member behind the user or performer. The connecting member is joined to an arm that is connected to at a back member that allows the back member to pivot and translate relative to the two shoulder supporting members to allow the back member to align with a back of a user. The connecting member may be joined to the one arm with a frictional connection. The arm may be connected to the back member with a frictional connection. The back member at least partially contours to the shape of the back and may further include an inflatable cushioning bladder and is positioned between and under shoulder blades of the user to increase arm mobility.

  • Patent number: 10885888
    Abstract: Improvements in a tilting, lifting stand are presented. The tilt, lift stand is for a musical instrument stand or to elevate/tilt a speaker and or amplifier and rigidly supports a sousaphone brass type instruments, speaker or amplifier in an in a stored and in a playable or elevated position. The stand supports all or the majority of the weight of the instrument or speaker or amplifier in a static position to relieve the weight of the musical instrument or speaker or amplifier. The stand has legs that are extendable to rest on multiple levels as might be found in a stadium. The stand further has a securing mechanism that gently grasps a tubular section to hold the musical instrument. The speaker stand can be easily collapsed for transportation and storage.

  • Patent number: 10460707
    Abstract: A snare drum attachment is disclosed. A mounted body is mounted to the snare drum and houses a first magnet. A moveable body is coupled to the mounted body. The moveable body is configured to retain tensioned snares a set distance from a snare head of the snare drum. The moveable body houses a second magnet magnetically coupled to the first magnet so as to generate a magnetic force. A manual actuator is coupled to the first magnet. Actuation of the manual actuator alters the magnetic force so as to displace the moveable body relative to the mounted body. The displacement changes the set distance of the tensioned snares from the snare head.

  • Patent number: 10438571
    Abstract: A marching drum articulation dampener for percussion instrument holder that allows attachment to a user mounted carrier. The holder allows adjustment for positioning about the user, and pivoting of the holder to allow the holder to pivot or rotate up to allow the holder with instruments to fit a narrower space. The holder further allows the pivotal attachment of individual drums to link or pivot allowing the linked drums to articulate. The holder can also consist of members that allow a connected drum to move in horizontal position, angle, or height of the drum. A plurality of unique drum connecting members is disclosed that allow the connecting members to connect onto drum tension rods or on a drum lug. A lift assisting mechanism is used to assist in lifts drums from a horizontal to a vertical orientation.
