Apparatus for sighting a projectile firing weapon

Claim 2

Apparatus for sighting a manually supported projectile firing weapon at a target comprising: a support element fixed with respect to said target; first means mounted on said support element for producing a first signal sensible to a person using said weapon when said weapon is oriented for firing at a pre-selected elevation; second means mounted on said support element for producing a second signal sensible to a person using said weapon when said weapon is oriented for firing at a pre-selected azimuth; third means mounted on said weapon for acutating said first means and said second means when said weapon is oriented at said pre-selected elevation and azimuth for firing at said target, whereby the user of said weapon is alerted by said signals that said weapon is in position for firing its projectile at said target.

Claim 3

Apparatus according to claim 1, wherein said first means comprises: an elongated arm pivotably connected to said support element for rotation through a plurality of elevational positions; a first signal generator having actuator elements located on said arm in position to be acutated by said third means when said weapon is oriented at said pre-selected elevation.

Claim 4

Apparatus according to claim 1, wherein said second means comprises: an elongated arm pivotably connected to said support element for rotation through a plurality of azimuthal positions; a signal generator having actuator elements located on said arm in position to be acutated by said third means when said weapon is oriented at said preselected azimuth.

Claim 5

Apparatus according to claim 1, wherein said third means comprises an electrically conductive rod mounted on said weapon; and said first and second means comprise electrical signal generators having input terminals positioned to be bridged by said rod to enable said generators to produce said signals.

Claim 6

Apparatus according to claim 1, wherein said first and second means comprise an elongated arm pivotably mounted to said support element for selective rotation through a plurality of elevational and azimuthal positions; first and second spaced, elongated electrical contact elements mounted on said arm and oriented essentially transversely thereto; a third electrical contact element mounted on said arm; a first electrical signal generator having its power input connected across said first and second contact elements; a second electrical signal generator having its power input connected across one of said first or second contact elements and said third contact element; and said third means comprises an electrically conductive element mounted on said weapon in position to close an electrical circuit between said first and second contact elements when said weapon is oriented at said pre-selected azimuth and to close an electrical circuit between said one of said first or second contact elements and said third contact element when said weapon is oriented at said pre-selected elevation; whereby said signal generators are energized when said weapon is in position for firing its projectile at said target.

Claim 7

Apparatus according to claim 5, further comprising positioning means mounted on said arm and spaced from said third contact element, for positioning said electrically conductive element at a fixed location relative to said third contact element.

Claim 8

Apparatus according to claim 1, wherein said weapon is an archery bow and arrow, wherein said first means comprises: a bow engaging means fixedly positioned relative to said support element for locating the lower end of the bow relative to said support element; an elongated arm pivotably connected to said support element for rotation through a plurality of elevational positions; a first signal generator having actuator elements located on said arm in position to be actuated by said third means when said weapon is oriented at said pre-selected elevation.

Claim 9

Apparatus according to claim 7, further comprising a body engaging means fixedly positioned relative to said support element for positioning the user of said weapon.

Claim 10

Apparatus according to claim 1, wherein said weapon is an archery bow and arrow, wherein said second means comprises: a bow engaging means fixedly positioned relative to said support element for locating the lower end of the bow relative to said support element; an elongated arm pivotably connected to said support element for rotation through a plurality of azimuthal positions; a signal generator having actuator elements located on said arm in position to be actuated by said third means when said weapon is oriented at said pre-selected azimuth.

Claim 11

Apparatus according to claim 9, further comprising a body engaging means fixedly positioned relative to said support element for enabling an archer to position himself relative to said support element.
