FIELD OF THE INVENTION
The present invention relates to firearms in general and, in particular, to a buttstock with a periscope assembly.
BACKGROUND OF THE INVENTION
When firing firearms, the force of the expanding gas that propels the bullet down the barrel forces the firearm rearwards in a recoil action. Accordingly, many firearms, such as rifles, shotguns, and other types of firearms, include a buttstock for engaging the shooter's shoulder when firing the firearm to help support the firearm during a recoil action.
Numerous firearms include or may be modified to include an adjustable buttstock. Adjustable and/or collapsible buttstocks allow a user to change a length of pull and overall firearm length to suit a specific user and/or a specific situation (e.g., to compensate for a user with longer or shorter arms or a user wearing thicker clothes, including body armor).

DETAILED DESCRIPTION OF EMBODIMENTS
Reference is now made to FIGS. 1-4, which illustrate a buttstock periscope assembly 10, in accordance with a non-limiting embodiment of the present invention.
The assembly includes a buttstock 12, which may be externally constructed to fit many firearms, such as rifles, shotguns, and other types of firearms, as is known in the art. As such, for example, the buttstock 12 may be an adjustable buttstock that includes a lock release lever 11 and an aperture 13 for a strap or a strap quick release mechanism (not shown).
As seen in FIG. 2, the buttstock periscope assembly 10 may include an image receiving surface 14 and an image viewing surface 16 mounted in or on buttstock 12, such as in a hollow portion 17 of buttstock 12. In this embodiment, image receiving surface 14 and image viewing surface 16 are both reflective surfaces (mirrors) which are pivoted about pivots 18 and 20, respectively. In FIGS. 1 and 2, the image receiving and image viewing surfaces 14 and 16 are in retracted positions, whereas in FIGS. 3 and 4, they have been pivoted to be in deployed positions. The pivots 18 and 20 may include lockable pivots (e.g., with detents or ratchets or other elements) which lock in the retracted and deployed positions so that they remain steady during firing of the firearm.
In the deployed position, image receiving surface 14 and image viewing surface 16 are spaced from each other, and the image receiving surface 14 is aligned with a shooting axis 15 (FIG. 4) associated with buttstock 12 (which is the shooting axis of the weapon) so that image receiving surface 14 is configured to capture images of the target the shooter wishes to shoot. The images captured by image receiving surface 14 are viewed by the shooter at image viewing surface 16. Thus, image receiving surface 14 and image viewing surface 16 form a periscope.
Buttstock 12 may include an inclined surface 22 upon which the image viewing surface 16 can abut or rest in the deployed position. Buttstock 12 may include a viewing window 24 for viewing the image viewing surface 16. Window 24 may be open or may be closed with a transparent cover. As seen in FIG. 25, a shooter can stand behind a protective wall 7 and use the periscope assembly 10 of the invention to shoot a weapon 8 safely behind the protective wall 7. It is seen that the image receiving surface 14 is aligned with one or more sights 9 of weapon 8.
Reference is now made to FIGS. 5-8, which illustrate another version of the buttstock assembly, with like elements being designated by like numerals. In this version, the image receiving surface 14 is stored in a folded position (FIGS. 5 and 6), in which image receiving surface 14 is turned about a longitudinal axis 26 (such as by 90°) of the buttstock 12 (the longitudinal axis 26 is the shooting axis or parallel thereto). Accordingly, in this embodiment, the image receiving surface 14 is mounted on a gimbal 28 so that the image receiving surface 14 is pivotable in two angular directions: elevation (between the retracted and deployed positions about pivot 18, as described above) and roll (about the longitudinal axis 26).
FIGS. 7 and 8 show the image receiving surface 14 of the periscope pivoted in roll to a pre-deployed position. FIGS. 9 and 10 show the image receiving surface 14 in the deployed position.
Reference is now made to FIGS. 11 and 12, which illustrate another version of the buttstock assembly, with like elements being designated by like numerals. In this version, a first rear access door 30 covers (protects) the image receiving surface 14 of the periscope. First door 30 may be hinged, and when opened, provides access to image receiving surface 14 so that image receiving surface 14 can be rotated from the retracted position (FIGS. 11 and 12) to the deployed position (FIGS. 13 and 14). (Actually FIGS. 13 and 14 show image receiving surface 14 on its way to the deployed position as indicated by arrow 23 in FIG. 14.)
Reference is now made to FIGS. 15 and 16, which illustrate another version of the buttstock assembly, with like elements being designated by like numerals. In this version, a second rear access door 32 covers (protects) the image viewing surface 16 of the periscope. The buttstock can alternatively be supplied with both first and second rear access doors 30 and 32.
Reference is now made to FIGS. 17 and 18, which illustrate another version of the buttstock assembly, with like elements being designated by like numerals. In this version, the buttstock assembly includes an image receiving surface 34 is a camera and an image viewing surface 36 which is a screen, which is configured to display images received by image receiving surface 34. The image receiving surface 34 and image viewing surface 36 together form a periscope. The image receiving surface 34 may be mounted on an arm 38 pivotable about a pivot 40. The image viewing surface 36 may be pivoted about a pivot 42. FIGS. 17-20 illustrate the image receiving and image viewing surfaces 34 and 36 at different angular positions (and different possible pivot arrangements).
Reference is now made to FIGS. 21-24, which illustrate another version of the buttstock assembly, with like elements being designated by like numerals. In this version, the image viewing surface 16 is not pivotable, but instead translatable. The image viewing surface 16 may be mounted on a sliding member 44, which slides in and out of the lower portion of buttstock 12 (“upper” and “lower” throughout are not limiting and merely refer to the view of the drawings). FIGS. 21 and 22 show the image receiving and image viewing surfaces 14 and 16 in retracted positions; FIGS. 23 and 24 show them in deployed positions.
