Abstract

Disclosed herein is an amusement device for squirting liquid. The amusement device includes a helmet having a squirt assembly connected thereto. The squirt assembly may be connected to a pump and a storage container for liquid via an umbilical cord as found in Sirhan, U.S. Pat. No. 4,903,864. The squirt assembly has a conduit extension connected to the umbilical cord. The squirt assembly further includes an aiming assembly supporting the conduit extension. The aiming assembly includes an azimuth and an elevation adjust for adjusting the conduit extension. A voice activated circuit activates and de-activates the pump upon receipt of an valid voice command. Upon receipt of a valid voice command, the pump is activated, liquid is pumped from the container to helmet through the umbilical cord and exits through the conduit extension, thereby enabling the hands free operation of the amusement device.

Claims

1. An amusement device for squirting liquid from a container having a pump and umbilical cord extending therefrom for transporting liquid therethrough, the amusement device comprising:

a helmet including a squirt assembly connected to the helmet, the squirt assembly connected to the pump and the container via the umbilical cord, the squirt assembly having a conduit extension connected to the umbilical cord, the squirt assembly including an aiming assembly supporting the conduit extension, the aiming assembly having an azimuth and elevation adjust means for adjusting the conduit extension; and

a voice activated circuit for activating and de-activating the pump upon receipt of an valid voice command,

whereby, upon valid voice command the pump is activated, liquid is pumped from the container to helmet through the umbilical cord and exiting through the conduit extension, thereby the operation of the amusement device is hands free.

2. An amusement device for squirting liquid as set forth in claim 1, wherein the squirt assembly includes a support bracket having a first and second leg mechanically connected to the helmet.

3. An amusement device for squirting liquid as set forth in claim 2, wherein the aiming assembly has an aiming arm which is connected to the first leg.

4. An amusement device for squirting liquid as set forth in claim 3, wherein the aiming assembly has an end support bracket approximately perpendicular to the aiming arm and wherein the end support bracket supports the conduit extension.

5. An amusement device for squirting liquid as set forth in claim 4, wherein the conduit extension has an end cap having a predetermined diameter "d" and the end cap has an opening of diameter "d"/420.

6. An amusement device for squirting liquid as set forth in claim 1, wherein the helmet includes a face guard which pivots about the helmet and wherein the face guard has a cross-hair circle for assisting in aiming the device.

7. An amusement device for squirting liquid as set forth in claim 1, wherein the helmet includes a removable and sealable enclosure for enclosing the voice activated circuit and thereby protecting the same.

8. An amusement device for squirting liquid as set forth in claim 7, wherein the enclosure has a series of cooling vents.

9. An amusement device for squirting liquid as set forth in claim 8, wherein the enclosure includes an on/off switch accessible from the outside of the helmet for enabling and disabling the a voice activated circuit.

10. An amusement device for squirting liquid as set forth in claim 6, wherein the voice activated circuit includes a microphone and wherein the microphone fits fully within the space of the face guard.

11. An amusement device for squirting liquid as set forth in claim 1, wherein the voice activated circuit comprises:

an on/off switch for enabling the voice activated circuit;

a portable battery for powering the circuit;

a microphone;

an amplification/detection circuit for detecting a valid voice command from an output of the microphone;

an integration and toggle circuit for filtering out extraneous noise and insuring a valid voice command, the integration and toggle circuit receives any output of the detection and amplification circuit and determines whether the output has been sustained for a long enough period of time to be a valid voice command; and

a pump relay driver circuit including a driver and a pump relay having normally closed contacts, the pump relay driver circuit receives any output of the integration and toggle circuit, the relay contacts are pulled open as long as no output is detected from the integration and toggle circuit, upon the detection of an output from the integration and toggle circuit as a result of a valid voice command, the driver releases the normally closed contacts allowing the pump to be activated when the "on/off" switch enables the circuit.

12. An amusement device for squirting liquid as set forth in claim 11, wherein the voice activated circuit includes a means for adjusting the percentage of output of the microphone which is received.

13. An amusement device for squirting liquid as set forth in claim 12, wherein the voice activated circuit includes a means for adjusting the minimum time period for determining whether a valid voice command has been received.
