Abstract

A miniaturized electronic transmitter tracking device (10) for mounting on the shaft of a hunting arrow (12) is provided. An integral membrane or diaphragm (38) attaches the transmitter to the arrow (12) in the preferred embodiment and allows the transmitter to break away from the arrow when the arrow strikes some object. A membrane switch (32) is activated when the face plate (40) of the device (10) impacts the animal. Barbed points (42) are driven into the surface of the struck animal by the force of the impact, thus firmly attaching the device (10) to the object. In its preferred embodiment, the transmitter device (10) is used in conjunction with a base receiver (16) to determine the transmitter'"'"'s location after the arrow (12) has been fired.

Claims

1. An arrow/wounded animal tracking device for mounting on the shaft of an arrow for use in conjunction with a receiver having directional finding capability, said device comprising:

a housing defining an opening therethrough for slidably receiving said shaft of said arrow;

means for releasably securing said housing to said shaft of said arrow as said shaft is received in said opening; and

signal generating means housed within said housing for generating a signal for being received by said receiver to facilitate the tracking of said arrow/wounded animal.

2. An arrow/wounded animal tracking device for mounting on the shaft of an arrow for use in conjunction with a receiver having directional finding capability, said device comprising:

a housing defining an opening therethrough for receiving said shaft of said arrow;

means for releasably securing said housing on said shaft of said arrow said means comprising a membrane mounted in said opening of said housing for circumscribing, and friction-fit engagement of, said shaft of said arrow; and

signal generating means housed within said housing for generating a signal for being received by said receiver to facilitate the tracking of said arrow/wounded animal.

3. The arrow/wounded animal tracking device of claim 2 wherein said device further comprises switch means for energizing said signal generating means when said arrow impacts an animal, said switch means including a switch for actuating said signal generating means, and including a rearwardly depressible switch actuating member mounted in said forward portion of said housing for engaging said animal upon impact of said arrow with said animal and for engaging and actuating said switch upon being rearwardly depressed, whereby the impact of said actuating member with said animal rearwardly depresses said actuating member thereby actuating said switch.

4. An arrow/wounded animal tracking device for mounting on the shaft of an arrow for use in conjunction with a receiver having directional finding capability, said device comprising:

a housing for being releasably secured on said shaft of said arrow, said housing having a forward portion and a rearward portion;

signal generating means housed within said housing for generating a signal for being received by said receiver to facilitate the tracking of said arrow/wounded animal; and

switch means for energizing said signal generating means when said arrow impacts an animal, said switch means including a switch for actuating said signal generating means, and including a rearwardly depressible switch actuating member mounted in said forward portion of said housing for engaging said animal upon impact of said arrow with said animal and for engaging and actuating said switch upon being rearwardly depressed, whereby the impact of said actuating member with said animal rearwardly depresses said actuating member thereby actuating said switch.

5. The arrow/wounded animal tracking device of claim 4 wherein said device further comprises means for the attachment of said housing to said animal.

6. The arrow/wounded animal tracking device of claim 5 wherein said actuating member includes a face plate member and wherein said means for the attachment of said housing to said animal includes at least one forwardly disposed barbed member mounted on said face plate.
