Abstract
Aiming apparatus rotatably attachable to optical sights e.g. conventional optical or laser sights which selectively permits the aiming of a weapon from a variety of cover positions. More specifically, aiming apparatus which may be field switched from an “aim from cover” mode to a conventional aim mode and which is connectable to a weapon sight in a 360 degree rotatable manner.
Claims23
Aiming apparatus comprising:
- means for rotatably connecting said aiming apparatus to a weapon sight;
- a first aperture located along a first axis for transmission of light images therethrough;
- a first body having a first reflective surface;
- a second body having a second reflective surface;
- said second body being pivotally moveable with respect to said first body between a first and a second position;
- wherein when said second body is oriented in said first position, light images which enter said aiming apparatus from a weapon sight enter through said first aperture along said first axis and exit through a second aperture located along said first axis;
- and
- wherein when said second body is oriented in said second position, light images which enter said aiming apparatus from a weapon sight enter through said first aperture along said first axis and are reflected by said second reflective surface to said first reflective surface whereby said first reflective surface reflects the light images such that the light images exit said aiming apparatus through a third aperture located along a second axis.

Aiming apparatus comprising:
- means for rotatably attaching said aiming apparatus to a weapon sight such that said aiming apparatus is continuously rotatable;
- a sight body including an image directing means, said sight body having a first aperture located along a first axis for entry of light images therethrough, and said sight body including a second aperture located along a second axis for exit of light images therethrough;
- wherein said image directing means is so located such that light images which enter said sight body through said first aperture enter at a first angle and impinge upon said image directing means and thereafter exit said sight body through said second aperture at a second angle different from said first angle.
Aiming apparatus comprising:
- means for rotatably attaching said aiming apparatus to a weapon sight such that said aiming apparatus is continuously rotatable;
- a sight body including an image directing means, said sight body having a first aperture located along a first axis for entry of light images therethrough, and said sight body including a second aperture located along a second axis for exit of light images therethrough;
- wherein said image directing means is so located such that light images which enter said sight body through said first aperture enter at a first angle and impinge upon said image directing means and thereafter exit said sight body through said second aperture at a second angle different from said first angle;
- and
- wherein said means for rotatably attaching said aiming apparatus permits said aiming apparatus to be rotatable about said first axis substantially 360 degrees.

- wherein said image directing means is so located such that light images which enter said sight body through said first aperture enter at a first angle and impinge upon said image directing means and thereafter exit said sight body through said second aperture at a second angle different from said first angle;
- and
- wherein said second angle is oriented approximately 40-90 degrees from said first angle.
