Abstract
Abstract A drum pedal device for immediately and accurately triggering and controlling a synthesizer. The device includes a movable pedal, which can be a foot pedal, an actuation device which actuates a transducer to supply an electrical signal to the synthesizer upon movement of the pedal, and a resisting mechanism which resiliently resists overtravel movement of the pedal after the transducer is actuated. The resisting mechanism opposes the movement of the pedal with increasing force as the overtravel movement of the pedal progresses. The foot pedal can be pivotally mounted on a base and the device can have a biasing mechanism for controlling and imparting bouncing and rocking motion to the foot pedal.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
98 words
A drum pedal device for triggering and controlling a synthesizer, comprising: transducer means for supplying an electrical signal to said synthesizer; actuation means for actuating said transducer means upon impact between said transducer means and said actuation means; a movable pedal coupled to said actuation means to cause said impact between said actuation means and said transducer means upon movement of said pedal, said pedal being adapted for overtravel movement after said impact occurs; and resisting means for resiliently resisting said overtravel movement after actuation of said transducer means, thereby simulating the action of an acoustic drum pedal.
Claim 2
Dependent Claim
98 words
A drum pedal device for triggering and controlling a synthesizer, comprising: transducer means for supplying an electrical signal to said synthesizer; actuation means for actuating said transducer means upon impact between said transducer means and said actuation means; a movable pedal coupled to said actuation means to cause said impact between said actuation means and said transducer means upon movement of said pedal, said pedal being adapted for overtravel movement after said impact occurs; and resisting means for resiliently resisting said overtravel movement after actuation of said transducer means, thereby simulating the action of an acoustic drum pedal.
Claim 3
Dependent Claim
21 words
The device of claim 1 wherein said resisting means opposes movement of said pedal with increasing force as said overtravel progresses.
Claim 4
Dependent Claim
13 words

Claim 8
Dependent Claim
32 words
The device of claim 1, wherein said resisting means includes a resilient biasing element capped at one end by said transducer means and at the other end by an energy absorbing member.
Claim 9
Dependent Claim
38 words
The device of claim 7, wherein said resisting means further includes guide pin means, secured to said transducer means and surrounded by said biasing element, for stabilizing said actuation means and retaining the shape of said biasing element.
Claim 10
Dependent Claim
17 words
The device of claim 1, wherein said resisting means includes a biasing element capped by a plate.
Claim 11
Dependent Claim
37 words
The device of claim 9, wherein said resisting means includes guide pin means, secured to said transducer means and surrounded by said biasing element, for stabilizing said actuation means and retaining the shape of said biasing element.
Claim 12
Dependent Claim
37 words
The device of claim 1 further comprising: a housing which contains said transducer means; a support plate; and a shock pad for cushioning shock to said transducer, said pad being arranged between said housing and said plate.
Claim 13
Dependent Claim
53 words
The device of claim 1, further including: a base to which said pedal is pivotally connected; and biasing means for controlling and imparting bouncing and rocking motion to said pedal, said biasing means being located toward the rear of said pedal and said base and being connected to said pedal and said base.
Claim 14
Dependent Claim
37 words
The device of claim 12 wherein said biasing means includes a spring capped on one end by an annular stud connected to said pedal and on the other end by an annular stud connected to said base.
Claim 15
Dependent Claim
27 words
The device of claim 12 wherein said base defines a series of bores spaced longitudinally along said base and said pedal for optionally receiving said biasing means.
Claim 16
Dependent Claim
50 words
The device of claim 1, further including: a base to which said pedal is pivotally connected; and adjustable biasing means secured to said base and facing said pedal for arresting the downward movement of said pedal at selected stages of the pivotal movement of said pedal relative to said base.
Claim 17
Dependent Claim
61 words
The device of claim 15, wherein said adjustable biasing means includes: an externally threaded member secured to said base and facing said pedal; and an adjustable spring capped at one end by a first internally threaded disc which is received by said theaded member, said spring being capable of having its position adjusted by threading said disc along said threaded member.
Claim 18
Dependent Claim
25 words
The device of claim 16, wherein said adjustable biasing means further includes means located along said threaded member for locking said adjustable spring in place.
