Patent number: 9640154Abstract: Drum pedal assemblies are disclosed which can include one or more adjustment features. Adjustment features which can be included in embodiments of the present disclosure can include components for adjusting pedal angle and/or height, and the resistance offered by the pedal (such as due to a spring connection). Pedal assemblies according to some embodiments of the present disclosure can include rotatable base plates for easy storage and travel. Pedal assemblies according to some embodiments the present disclosure can include securing means such as retractable spikes for stabilizing the pedal assembly.Type: GrantFiled: January 20, 2016Date of Patent: May 2, 2017Assignee: DRUM WORKSHOP, INC.Inventor: Richard A Sikra

Patent number: 9601096Abstract: A clutch for use in a hi-hat percussion assembly is disclosed. The clutch can included a threaded bolt that includes slots, and a nut that includes an indexing means such as a plunger. An elastic holding means can be used to exert pressure on the indexing means, such as when the indexing means is rigid, for example. The plunger can be configured to engage a slot upon rotation of the nut to lock the nut into place. While in a locked position, unwanted displacement of the nut, including rotational displacement that may be caused by forceful and rapid movements of a drummer, can be reduced, prevented, and/or eliminated. Using a force greater than that required to simply turn the nut while in an unlocked position, the nut can be rotated to disengage the plunger from the slot and return the nut to an unlocked position.Type: GrantFiled: October 3, 2014Date of Patent: March 21, 2017Assignee: DRUM WORKSHOP, INC.Inventor: Richard A. Sikra
