Abstract
A foot-operated, bass drum pedal assembly is provided, and it includes: a base in the form of a metal plate, a first drum beater, a support for the beater mounted on the base, and a pedal pivotally mounted to the base and operatively connected to the beater to pivot same as the pedal is pivoted by the drummer's foot, and structure located proximate the pedal to sense downward movement of the pedal to predetermined downward position, and to produce an electrical signal usable to effect production of phenomena corresponding to a drum beat.
Claims19
In drum beating apparatus, the combination comprising:
- (a) a bottom, horizontally extending support plate,
- (b) upright structure attached to and supported by the plate,
- (c) a horizontal axle supported by said structure for rotation about a horizontal axis,
- (d) a sprocket carried by the axle at a support location, the sprocket having peripheral chain engaging teeth, and a chain meshing with said teeth, an end portion of the chain anchored to the sprocket, the chain having a dangling portion extending below the sprocket,
- (e) a pedal having a rear portion hingedly supported by the plate and a front portion attached to said dangling portion of the chain,
- (f) and means located proximate the pedal to sense downward movement of the pedal to predetermined downward position, and to produce an electrical signal usable to effect production of phenomena corresponding to a drum beat.
In a foot-operated, base drum pedal assembly, the combination comprising:
- (a) a forwardly elongated, horizontally extending base plate,
- (b) a sub-assembly including two upright pedestals and a yoke, the yoke attached to the base plate,
- (c) an axle shaft extending between and rotatably supported by the two pedestals, and defining an axis,
- (d) a drum stick carried by said axle shaft to be rotated thereby, to beat a drum,
- (e) a toothed sprocket mounted on the shaft to rotate same, about said axis,
- (f) a chain entrained on the sprocket teeth and having opposite end portions one of which is anchored to the sprocket, above the base plate, the chain extending at increasing distance from the axis along the chain length away from anchored end portion, and
- (g) a pedal extending in inclined relation to and above the base plate, the pedal having a rear end portion pivotally connected to the base plate near the rearward end thereof, the pedal having a forward end portion attached to the other end portion of the chain, below the level of the sprocket, and above a forward end portion of the base plate.
- (h) and means located proximate the pedal to sense downward movement of the pedal to predetermined downward position, and to produce an electrical signal usable to effect production of phenomena corresponding to a drum beat.
In a drum beating assembly the combination comprising:
- (a) a base in the form of a metal plate, a first drum beater, a support for the beater mounted on the base, and a pedal pivotally mounted to the base and operatively connected to the beater to pivot same as the pedal is pivoted by the drummer's foot,
- (b) and means located beneath and proximate the pedal to sense downward movement of the pedal to predetermined downward position, and to produce an electrical signal usable to effect production of phenomena corresponding to a drum beat,
- (c) said beater support including upright structure on the plate, an axle carried by said structure, the beater mounted on the axle, there being a rotor on the axle and a flexible member connecting the rotor to the forward extent of the petal.
