Abstract

Apparatus for preventing injury to fielders, including control means to be actuated by a coach or other person or persons, and separate fielder units to be carried by different fielders and adapted to receive radio signals from the control means and produce signals which can be sensed by the fielder to indicate to him which of the fielders is nearer to the ball and should field it.

Claims

1. Baseball fielder signaling apparatus comprising:

control means to be operated by a person or persons positioned to view at least two fielders in a baseball game, and including radio transmitter means operable to transmit selectively different radio signals under the control of said person or persons for instructing adjacent fielders as to which should attempt to field a particular batted ball;

a plurality of fielder units each unit to be carried on the person of a fielder and each including receiver circuitry for receiving said transmitted signals from said control means, and means operable by said receiver circuitry to produce output signals controlled by said radio signals and which can be sensed by the fielder and indicate to him which of the fielders is to field the ball;

said means operable by said receiver circuitry including light emitting means responsive to said radio signals, and reflector means for reflecting light from said light emitting means toward the eyes of the fielder; and

caps carried by said fielders and having bills carrying said reflector means at their undersides.

2. Baseball fielder signaling apparatus comprising:

control means to be operated by a person positioned to view two adjacent first and second fielders in a baseball game, and including radio transmitter means operable to transmit selectively two different radio signals under the control of said person for instructing said adjacent fielders as to which should attempt to field a particular batted ball;

said control means including manually operated means actuable by said person between a first condition causing said transmitter means to transmit a first of said radio signals and a second condition causing said transmitter means to transmit a second of the radio signals; and

first and second fielder units constructed and adapted to be worn by said two adjacent fielders respectively during a game in a manner avoiding substantial interference with their movements in fielding a ball;

said first fielder unit being constructed to receive said first radio signal and produce in response thereto but not in response to said second signal an output which can be sensed by the first fielder and indicate to him whether he is to field the ball;

said second fielder unit being constructed to receive said second radio signal and produce in response thereto but not in response to said first radio signal an output which can be sensed by the second fielder and indicate to him whether he is to field the ball.

3. Baseball fielders signaling apparatus as recited in claim 2, including additional control means to be operated by a second person positioned to view said second fielder and a third fielder, and including additional radio transmitter means operable to transmit selectively two different radio signals under the control of said second person for instructing said second and third fielders as to which should attempt to field a particular batted ball;

said additional control means including additional manually operable means actuable by said second person between different conditions for transmitting different radio signals; and

a third fielder unit constructed to be worn by said third fielder during a game in a manner avoiding substantial interference with his movements in fielding a ball;

said second and third fielder units being constructed to receive said different signals respectively transmitted by said additional transmitter means and produce outputs which can be sensed by said second and third fielders to indicate which of them is to field a particular ball.

4. Baseball fielder signaling apparatus as recited in claim 3, in which one of said radio signals transmitted by said additional transmitter means corresponds to said second signal produced by said first mentioned transmitter means so that said second fielder unit can be controlled by either of said control means to instruct said second player whether he is to field a particular ball.

5. Baseball fielder signaling apparatus as recited in claim 2, in which said outputs produced by said first and second signals indicate to the respective fielders that they are to field the ball;

said transmitter means being actuable by said manually operable means to transmit two additional signals receivable by said two fielder units respectively, said fielder units having means responsive to said additional signals to produce outputs instructing the respective fielders not to field a particular ball.

6. Baseball fielder signaling apparatus as recited in claim 2, in which each of said fielder units includes two lights visible by a fielder wearing that particular unit and giving different visible signals controlled by said transmitter means to indicate to the fielder that he is to field a particular batted ball if a first of the lights is on and that he is not to field the ball if a second of the lights is on.

7. Baseball fielders signaling apparatus as recited in claim 2, in which each of said fielder units includes light emitting means controlled by said transmitter means, and reflector means for reflecting light from said light emitting means toward the eyes of the fielder.

8. Baseball fielders signaling apparatus as recited in claim 7, including caps carried by said fielders and having bills carrying said reflector means at their undersides.

9. Baseball fielders signaling apparatus as recited in claim 2, in which said fielder units include sound producing means responsive to said radio signals for producing two different sounds indicating which of said two fielders is to field a particular batted ball.

10. Baseball fielders signaling apparatus as recited in claim 2, in which said fielder units include both light emitting means and sound emitting means producing visible and audible output signals controlled by said radio signals for indicating which of two fielders is to field a ball.

11. Baseball fielders signaling apparatus as recited in claim 2, including a third fielder unit to be carried by a third fielder, said control means including a single control unit in which said transmitter means are operable to transmit a third radio signal in addition to said first and second signals, said manually operated means being operable to actuate said transmitter means to transmit said third signal;

said third fielder unit being responsive to said third radio signal to produce an output instructing said third fielder whether he is to field a particular batted ball.

12. Baseball fielders signaling apparatus as recited in claim 2, in which said control means include a single control unit to be held by a person;

said transmitter means being operable to transmit third and fourth radio signals in addition to said first and second signals;

said manually operated means including four manually actuated switches each operable when actuated to cause said transmitter means to transmit one and only one of said four radio signals, said first fielder unit being constructed to receive said third radio signal but not said fourth signal, said second fielder unit being constructed to receive said fourth radio signal but not said third radio signal, said first fielder unit being responsive to said first and third radio signals to produce different outputs adapted to be sensed by the corresponding fielder and instruct him whether he is or is not to field a particular ball, and said second fielder unit being constructed to respond to said second and fourth radio signals to produce two different outputs instructing said second fielder whether he is or is not to field a particular ball.

13. Baseball fielders signaling apparatus as recited in claim 2, including a third of said fielder units to be worn by a third fielder, said control means including a single control unit operable to transmit six different radio signals, only two of which are receivable by each of said fielder units, said manually operated means including six manually actuated elements operable to actuate said transmitter means to transmit said six different radio signals respectively;

each of said fielder units being operable to produce two different outputs in response to two of said radio signals respectively which can be sensed by a corresponding one of the players to indicate whether he should or should not field a particular ball.
