Abstract

Method and apparatus for simulating trap shooting by utilizing a pair of separate electrical drive motors to move a light source about two separate axes. Control structure provide a logic sequence of operation causing the light source to project a beam of light having only upward vertical motion at a random azimuthal angle to simulate the flight of objects in trap shooting.

Claims

1. A method of simulating the flight of objects in trap shooting, comprising the steps of:

pivoting a de-energized light source back and forth through a range of azimuthal angles;

randomly stopping said pivoting motion to set the light source at a random one of the azimuthal angles, and substantially simultaneously therewith energizing the light source and starting generally upward vertical movement of the light source from a preselected minimum vertical position along the random azimuthal angle;

de-energizing the light source as the latter reaches a preselected maximum vertical position;

restarting said pivoting back and forth motion;

driving the light source vertically downwardly to said preselected minimum vertical position; and

stopping vertical motion upon reaching said minimum vertical position.

2. A method as set forth in claim 1, wherein vertical motion is accomplished by rotating the light source about a first axis up and down through a preselected vertical arc in a motion starting and ending at said minimum vertical position relative to said first axis.

3. A method as set forth in claim 2, wherein said pivoting motion is accomplished by rotating the light source such that said first axis rotates back and forth through a preselected arc about a second axis extending generally perpendicularly to a plane containing said first axis.

4. A method as set forth in claim 3, wherein restarting of said pivoting back and forth motion occurs substantially simultaneously with de-energization of said light source.

5. A method as set forth in claim 4, further including the step of energizing an indicator light whenever rotation of the light source in said vertical arc ceases.

6. A projector for simulating trap shooting, comprising:

a light source for projecting a beam of light simulating the flight of objects in trap shooting;

first drive means for moving said light source generally vertically up and down between preselected maximum and minimum vertical positions;

second drive means for moving said light source back and forth through a range of azimuthal angles; and

control means for controlling actuation of said first and second drive means and energization of the light source to randomly stop back and forth movement of said second drive means and to substantially simultaneously therewith start said first drive means for initiate upward vertical movement of said light source from said minimum vertical position along a random one of the azimuthal angles and energize said light source whereby said light source projects an upwardly moving beam of light along said random azimuthal angle, said control means also being for selectively stopping vertical movement when said light source returns to said minimum vertical position.

7. A projector as set forth in claim 6, further including a base, a frame movably mounted to said base, said light source being movably mounted to said frame, said first drive means being carried by said frame, and said second drive means being carried by said base.

8. A projector as set forth in claim 7, wherein said first drive means includes a first rotatable electric motor, and first linkage extending between said first motor and said light source for pivoting said light source about a first axis upwardly and downwardly through a preselected generally vertical arc.

9. A projector as set forth in claim 8, wherein said second drive means includes a second rotatable electric motor, and second linkage extending between said second motor and said frame for pivoting said frame about a second axis extending perpendicularly to the plane containing said first axis in a manner causing said first axis to rotate back and forth about said second axis between preselected limits.

10. A projector as set forth in claim 6, wherein said control means includes first circuit means for substantially simultaneously stopping said second drive means, energizing said light source, and starting said first drive means.

11. A projector as set forth in claim 10, wherein said control means further includes sensor means for sensing the vertical position of said light source, and second circuit means responsive to said sensor means and operable upon said light source reaching said maximum vertical position to substantially simultaneously de-energize said light source and restart said second drive means.

12. A projector as set forth in claim 11, wherein said control means further includes third circuit means responsive to said sensor means and operable upon said light source reaching said miminum vertical position to stop said first drive means.

13. A projector as set forth in claim 12, further including an indicator lamp, said third means operably coupled with said indicator lamp to energize the latter whenever said light source is at said minimum vertical position.

14. In combination with a projector as set forth in claim 6, a gun having a second light source thereon for simulating firing of the gun, and a switch operated by the trigger of said gun for actuating said second light source.

15. In combination as set forth in claim 14, a solenoid mounted to the stock of said gun and operated by said switch for simulating recoil upon energizing said second light source.

16. A method of simulating the flight of objects in trap shooting, comprising the steps of:

providing a light source mounted about a first axis for movement through a generally vertical arc;

pivoting the light source such that said first axis rotates back and forth through a preselected arc about a second axis generally perpendicular to a plane containing said first axis whereby the light source is moved through a range of azimuthal angles;

selectively stopping said pivoting motion to set the light source at one of the azimuthal angles and substantially simultaneously therewith energizing the light source and rotating the light source generally upwardly from a minimum vertical position about said first axis and along the one azimuthal angle;

de-energizing the light source when said light source reaches a maximum vertical position, and substantially simultaneously therewith restarting pivoting motion;

driving the light source vertically downwardly to said minimum vertical position; and

substantially simultaneously stopping vertical motion of the light source and energizing an indicator light upon reaching said minimum vertical position.

17. A projector for simulating trap shooting, comprising:

a light source for projecting a beam of light simulating the flight of objects in trap shooting;

first drive means for moving said light source generally vertically up and down between preselected maximum and minimum vertical positions;

second drive means for moving said light source back and forth through a range of azimuthal angles;

control means for controlling actuation of said first and second drive means and energization of said light source, said control means including first circuit means for substantially simultaneously stopping said second drive means, energizing said light source, and starting said first drive means to drive said light source upwardly from said minimum vertical position, sensor means for sensing the vertical position of said light source, second circuit means responsive to said sensor means and operable upon said light source reaching said maximum vertical position to substantially simultaneously de-energize said light source and restart said second drive means, and third circuit means responsive to said sensor means and operable upon said light source returning to said minimum vertical position to stop said first drive means; and

an indicator lamp connected with said third circuit means for energization of said lamp when said light source is in said minimum vertical position.
