  • Patent number: 11037536
    Abstract: Drum pedal systems are disclosed which can include separate pedal and beater portions connected by a connecting portion. The connecting portion can be flexible such that the location of the beater portion can be adjusted relative to the location of the pedal portion. The pedal and beater portions can be disconnected from one another for improved transportability. Direct drive pedal systems are also disclosed, which can include separate pedal and beater portions connected by a direct drive connecting portion having rigid connections.

  • Patent number: 10943571
    Abstract: Percussion assemblies, such as mini hi-hat percussion assemblies, are disclosed. The mini hi-hat assemblies can include a first connecting portion between a pedal and a drive shaft. A roller can be included between the first connecting portion and an underside of the pedal. Non-flexible members and/or flexible members such as a chain can be included between the drive shaft and a cymbal rod. Actuation of the pedal can cause rotation of the drive shaft and downward movement of the cymbal rod, which can have a top cymbal mounted thereon. This downward movement can cause the top cymbal to contact a bottom cymbal and produce a desired sound. A compression spring can then cause the system to rebound toward its equilibrium or resting position.

  • Patent number: 10867589
    Abstract: Drum pedal systems are disclosed which can include separate pedal and beater portions connected by a connecting portion. The connecting portion can be flexible such that the location of the beater portion can be adjusted relative to the location of the pedal portion. The pedal and beater portions can be disconnected from one another for improved transportability. The pedal portion may include a roller beneath the pedal so as to increase the smoothness of play. The angle of the beater can be laterally adjusted, thus causing the contact point on a drum to be lower or higher as desired. The beater portion can include a beater axis that is relatively low to the ground, which can aid in preventing a user's hands and the beater striking a percussion instrument at the same height.

  • Patent number: 10737369
    Abstract: Nut devices including a butterfly portion with an axial hole that can be opened such that the nut device can be slid up or down a host device, such as a cymbal stand rod, without the typical screw-type motion, are disclosed. Also disclosed are nut devices including drum key functionality.

  • Patent number: 10699681
    Abstract: A transportable drum kit and components thereof are disclosed. The kit can include a stand that is connected to a bass drum, the stand having two legs that can provide support to the bass drum. The two legs can fold into a cavity of the bass drum. The kit can include a second drum supported by a leg. The two stand legs and the second drum leg can be on opposite sides of said bass drum so as to provide for triangulated support of the bass drum, resulting in less sound distortion than a bass drum that supports its own weight.

  • Patent number: 10249272
    Abstract: Percussion instruments such as cajóns including auxiliary devices such as snares are disclosed. The positioning of the auxiliary device or devices with respect to the main body of the percussion instrument can be adjustable so as to produce different sounds depending upon the auxiliary device position. In one embodiment, a lever device on the back of a cajón is used. The lever device is linked to one or more snares by an adjustment rod and/or an auxiliary bar. As the lever device is adjusted, the positioning of the one or more snares and the amount of the snare wires that is in contact with the back of the tapa is adjusted, resulting in different sounds when the cajón is played.
