Supplementary sight aid adaptable to existing and new sight aid

Abstract

A sight aid including a supplementary sight alignment indicator having a projection plane and a projection device adapted to project a supplementary sight alignment indicator and at least one reference point on the projection plane, the supplementary sight alignment indicator is axially-centered with respect to the sight alignment indicator and spaced apart therefrom on the optical axis for forming a composite image with the image of the sight alignment indicator, the target image being viewable together by the user by means of the ocular lens and the projection plane is disposed at a distance from the sight alignment indicator. An adaptor secures the supplementary sight alignment indicator to a portion of the projectile device or the housing.

What is claimed herein is: 
     
         1 . A sight aid for aiding aiming of a projectile device with respect to a target, said sight aid comprising:
 (a) a telescope having a housing, an objective lens mounted in the housing at one end thereof for forming a target image, an ocular lens mounted in the housing at an opposite end thereof and having image-erecting optics, a reticle mounted within the housing, wherein the objective and ocular lenses define an optical axis through the housing and the image-erecting optics are mounted between the objective and ocular lenses on the optical axis for erecting the image formed by the objective lens, where the erected image is formed for viewing by a user, the reticle having a sight alignment indicator on the optical axis, an image thereof being aligned with the target image formed by the objective lens and the image-erecting optics within the housing to facilitate alignment of the telescope with the target; and   (b) a supplementary sight alignment indicator comprising a pointed post comprising a post having a pointed end axially-centered with respect to said sight alignment indicator and spaced apart a distance therefrom along said optical axis for forming a composite image with said image of said sight alignment indicator and the target image being viewable together by the user by means of said ocular lens,   
       whereby an indication of deviation of said images of said axially-centered sight alignment indicator and axially-centered supplementary sight alignment indicator and said target image along the optical axis is provided to the user such that an action can be taken to remove such deviation to assure accurate alignment of the optical axis of said telescope with the target. 
     
     
         2 . The sight aid of  claim 1 , wherein said pointed post is configured to be slidingly and removably coupled to a rail such that the distance is adjustable. 
     
     
         3 . The sight aid of  claim 1 , wherein said pointed post comprises a post having a fixed width for substantially the entirety of its length and tapers inwardly and centrally to said pointed end. 
     
     
         4 . The sight aid of  claim 1 , wherein said pointed post comprises a cross-sectional profile that tapers inwardly and centrally from a base at a first end to said pointed end at a second end. 
     
     
         5 . The sight aid of  claim 1 , wherein said pointed post is configured to be removably attachable to said telescope. 
     
     
         6 . The sight aid of  claim 1 , wherein said pointed post is disposed between said image-erecting optics and the user and between said ocular lens and said objective lens. 
     
     
         7 . The sight aid of  claim 6 , further comprising a resilient circular frame disposed in a plane and having an opening, said pointed post is disposed such that said pointed post extends within said plane from said circular frame until said pointed end is centrally located within said opening, wherein said resilient circular frame is configured to be removably attached to a portion of said telescope. 
     
     
         8 . A sight aid for aiding aiming of a projectile device with respect to a target, said sight aid comprising:
 (a) a telescope having a housing, an objective lens mounted in the housing at one end thereof for forming a target image, an ocular lens mounted in the housing at an opposite end thereof and having image-erecting optics, a reticle mounted within the housing, wherein the objective and ocular lenses define an optical axis through the housing and the image-erecting optics are mounted between the objective and ocular lenses on the optical axis for erecting the image formed by the objective lens, where the erected image is formed for viewing by a user, the reticle having a sight alignment indicator on the optical axis, an image thereof being aligned with the target image formed by the objective lens and the image-erecting optics within the housing to facilitate alignment of the telescope with the target; and   (b) a supplementary sight alignment indicator comprising a pointed post comprising a post having a pointed end axially-centered with respect to said sight alignment indicator and spaced apart a distance therefrom along said optical axis for forming a composite image with said image of said sight alignment indicator and the target image being viewable together by the user by means of said ocular lens, wherein said pointed post is disposed between said image-erecting optics and the user and between said ocular lens and said objective lens,   
       whereby an indication of deviation of said images of said axially-centered sight alignment indicator and axially-centered supplementary sight alignment indicator and said target image along the optical axis is provided to the user such that an action can be taken to remove such deviation to assure accurate alignment of the optical axis of said telescope with the target. 
     
     
         9 . The sight aid of  claim 8 , wherein said pointed post is configured to be slidingly and removably coupled to a rail such that the distance is adjustable. 
     
     
         10 . The sight aid of  claim 8 , wherein said pointed post comprises a post having a fixed width for substantially the entirety of its length and tapers inwardly and centrally to said pointed end. 
     
     
         11 . The sight aid of  claim 8 , wherein said pointed post comprises a cross-sectional profile that tapers inwardly and centrally from a base at a first end to said pointed end at a second end. 
     
     
         12 . The sight aid of  claim 8 , wherein said pointed post is configured to be removably attachable to said telescope. 
     
     
         13 . The sight aid of  claim 12 , further comprising a resilient circular frame disposed in a plane and having an opening, said pointed post is disposed such that said pointed post extends within said plane from said circular frame until said pointed end is centrally located within said opening, wherein said resilient circular frame is configured to be removably attached to a portion of said telescope. 
     
     
         14 . A pointed post assembly adaptable to a telescope for parallax error elimination, said pointed post assembly comprising:
 (a) a pointed post having a base at a first end and a pointed end opposingly disposed from said first end; and   (b) a resilient circular frame disposed in a plane and having an opening, said pointed post is disposed such that said pointed post is attached at said base to said resilient circular frame such that said pointed end is centrally located within said opening within said plane, wherein said resilient circular frame is configured to be removably attached to a portion of the telescope.
