Abstract
A sensor for use with a compound archery bow of the type including a body, a bowstring for being drawn by an archer, and a cam for connecting the bowstring to the body. The sensor includes a switch for being closed by the cam in response to the drawing of the bowstring; a light for emitting light when electrically energized and activated; and an electrical energy source for electrically energizing and activating the light when the switch is closed.
Claims18
A sensor for use with a compound archery bow of the type including a body, a bowstring for being drawn by an archer, and cam means for connecting said bowstring to said body;
- said cam means including a body for being rotated when said bowstring is drawn;
- said sensor comprising:
- a) switch means for being closed by said cam means in response to the drawing of said bowstring;
- said switch means including a first contact member, a second contact member, and an electrically conductive plate member attached to said body of said cam means for rotation with said cam means and for closing an electrical circuit between said first and second contact members when both of said first and second contact members simultaneously contact said electrically conductive plate member;
- b) light means for emitting light when electrically energized and activated;
- and
- c) electrical energy source for electrically energizing and activating said light means when said switch means is closed.
A sensor for use with a compound archery bow of the type including a body, a bowstring for being drawn by an archer, and cam means for connecting said bowstring to said body, said cam means including a body for being rotated when the bowstring is drawn;
- said sensor comprising:
- a) switch means for being closed by said cam means in response to the drawing of said bowstring;
- said switch means including a first contact member, a second contact member, and an electrically conductive plate member attached to said body of said cam means for rotation with said cam means and for closing an electrical circuit between said first and second contact members when both of said first and second contact members simultaneously contact said electrically conductive plate member;
- the location of said electrically conductive plate member of said switch means on said body of said cam means being adjustable;
- b) light means for emitting light when electrically energized and activated;
- and
- c) electrical energy source for electrically energizing and activating said light means when said switch means is closed.
A sensor for use with a compound archery bow of the type including a body, a bowstring for being drawn by an archer, and cam means for connecting said bowstring to said body;
- said cam means including a body for being rotated when said bowstring is drawn;
- said sensor comprising:
- a) switch means for being closed by said cam means in response to the drawing of said bowstring;
- said switch means including a normally opened switch member;
- said switch means including a contact member attached to said body of said cam means for rotation with said cam means and for contacting said switch member and closing said switch member when said body of said cam means has rotated a predetermined amount in response to the drawing of said bowstring;
- b) light means for emitting light when electrically energized and activated;
- and
- c) electrical energy source for electrically energizing and activating said light means when said switch means is closed.
A sensor for use with a compound archery bow of the type including a body, a bowstring for being drawn by an archer, and cam means for connecting said bowstring to said body, said cam means including a body for being rotated when the bowstring is drawn;
- said sensor comprising:
- a) switch means for being closed by said cam means in response to the drawing of said bowstring;
- said switch means including a normally opened switch member having a plunger for being depressed to close said switch member;
- said switch member including a contact member attached to said body of said cam means for rotation with said cam means and for depressing said plunger of said switch member when said body of said cam means has rotated a predetermined amount in response to the drawing of said bowstring;
- the location of said contact member of said switch means on said body of said cam means being adjustable;
- b) light means for emitting light when electrically energized and activated;
- and
- c) electrical energy source for electrically energizing and activating said light means when said switch means is closed.
