Alignment device for a firearm

Abstract

An alignment device for a firearm, the alignment device being mountable on said firearm and being shaped to define, in at least one mode of use, a sighting aperture located adjacent a base of the device such that, when the base is positioned, in use, on a surface of the firearm, the sighting aperture is located adjacent said surface. The device comprises a body with an elongate aperture having a longitudinal axis extending in a first direction; and a cover mountable on the body and including at least one aperture that is at least partially in register with said elongate aperture during use. The body and the cover are slidable with respect to one another in said first direction. The device allows firearms, especially shotguns, to be correctly fitted to a user for various modes of shooting.

1 . An alignment device for a firearm, the alignment device being mountable on said firearm and being shaped to define, in at least one mode of use, a sighting aperture located adjacent a base of the device such that, when the base is positioned, in use, on a surface of the firearm, the sighting aperture is located adjacent said surface.  
   
   
       2 . An alignment device as claimed in  claim 1 , wherein said sighting aperture is open-ended such that, when fitted to said surface, the sighting aperture opens onto said surface.  
   
   
       3 . An alignment device as claimed in  claim 1 , wherein the device comprises a body shaped to define elongate aperture having a longitudinal axis extending in a first direction; and a cover mountable on the body and including at least one aperture that is at least partially in register with said elongate aperture during use, the body and the cover being movable with respect to one another substantially in said first direction.  
   
   
       4 . An alignment device as claimed in  claim 3 , wherein said elongate aperture is open-ended, opening onto the base of the device.  
   
   
       5 . An alignment device as claimed in  claim 3 , wherein said cover includes a notch formed in an edge of the cover and, when the cover is mounted on the body in at least one mode of use, the edge is located substantially at the base of the device.  
   
   
       6 . An alignment device as claimed in  claim 5 , wherein said notch is located substantially in register with the open end of said elongate aperture.  
   
   
       7 . An alignment device as claimed in  claim 3 , wherein said cover includes first and second apertures, each of said first and second apertures being located substantially in register with the longitudinal axis of the elongate aperture when the cover is mounted on the body.  
   
   
       8 . An alignment device as claimed in  claim 7 , wherein said first aperture comprises a notch formed in an edge of the cover and, when the cover is mounted on the body in at least one mode of use, the edge is located substantially at the base of the device, and said second aperture comprises an elongate aperture extending substantially in said first direction.  
   
   
       9 . An alignment device as claimed in  claim 3 , wherein said at least one aperture of the cover terminates in a cross piece, the cross piece obscuring part of said elongate aperture when the cover is mounted on the body in at least one mode of use.  
   
   
       10 . An alignment device as claimed in  claim 9 , wherein said first aperture is located substantially at one edge of the cover, the second aperture being located adjacent the opposite edge of the cover, said cross piece being defined between said second aperture and said opposite edge.  
   
   
       11 . An alignment device as claimed in  claim 9 , wherein said cross piece is defined between the first and second apertures.  
   
   
       12 . An alignment device as claimed in  claim 1 , wherein the device is mountable in a frame, the frame being mountable on at least one barrel of a firearm, the device being slidable with respect to the frame generally in said first direction.  
   
   
       13 . An alignment device for a firearm comprising at least one barrel, the alignment device being mountable on said at least one barrel and being shaped to define a sighting aperture, wherein the device comprises a body shaped to define elongate aperture having a longitudinal axis extending in a first direction; and a cover mountable on the body and including an elongate aperture having a longitudinal axis extending in said first direction and being at least partially in register with said elongate aperture of the body when the cover is mounted on the body in at least one mode of use, the body and the cover being movable with respect to one another substantially in said first direction, the sighting aperture being defined by the overlap between the respective elongate apertures of the cover and the body.
