Abstract
Abstract An improved illuminated drumstick of the type having a light-emitting diode powered by batteries. The improvements include a switch using a flexible metal strap over a resilient pad affixed to one end of the batteries. Additionally, the batteries may be connected by a thin flexible strap, and the light emitting diode is rectangular in shape and securely held in a channel at the tip of the drumstick.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
182 words
An improved illuminated drumstick of the type having a light emitting diode having two terminals in the tip thereof, one or more batteries held in the shaft thereof, each of said batteries having a cathode and an anode collector and a first end and a second end, a pair of conductors connected between the light emitting diode and the batteries, a switch and a transparent tip, wherein the improvement comprises: switch means comprising a longitudinally movable, electrically conductive shaft in contact with a conductor leading to one terminal of said light emitting diode; a flexible, conductive strap affixed to the cathode collector of one of said one or more batteries and extending over the second end thereof; a resilient pad positioned between said conductive strap and the second end of said battery, whereby when said longitudinally movable, electrically conductive shaft is moved inwardly to contact said conductive strap, said conductive strap is deformed inwardly while being urged outwardly by the deformation of said resilient pad thereby maintaining a continuous contact in spite of the impact caused by the use of said drumstick.
Claim 2
Dependent Claim
182 words
An improved illuminated drumstick of the type having a light emitting diode having two terminals in the tip thereof, one or more batteries held in the shaft thereof, each of said batteries having a cathode and an anode collector and a first end and a second end, a pair of conductors connected between the light emitting diode and the batteries, a switch and a transparent tip, wherein the improvement comprises: switch means comprising a longitudinally movable, electrically conductive shaft in contact with a conductor leading to one terminal of said light emitting diode; a flexible, conductive strap affixed to the cathode collector of one of said one or more batteries and extending over the second end thereof; a resilient pad positioned between said conductive strap and the second end of said battery, whereby when said longitudinally movable, electrically conductive shaft is moved inwardly to contact said conductive strap, said conductive strap is deformed inwardly while being urged outwardly by the deformation of said resilient pad thereby maintaining a continuous contact in spite of the impact caused by the use of said drumstick.
Claim 3
Dependent Claim
