(a) Technical Field of the Invention
The present invention is generally related to air guns, and more particular to an electric air gun's buttstock providing adjustment to fit various users.
(b) Description of the Prior Art
Due to the popularity of war games, air guns such as BB guns and paint guns are of great demand. Conventional air guns have fixed buttstocks and, as users are of various arm or neck lengths, these air guns are not suitable for each and every user, even though some of them are equipped with some minor adjustment mechanisms. For example, Taiwan Utility Model Application Serial No. 099220984 teaches an air gun containing a gun body and a buttstock. The buttock contains a cheek support assembly containing a cheek support member and a frame engaging the buttstock. The cheek support member is adjustable so as to be more ergonomic. But as mentioned above, this air gun is still not universally applicable to all users.
SUMMARY OF THE INVENTIONTherefore a novel buttstock is provided herein so as to obviate the shortcomings of the prior art.
According to the present invention, the buttstock for an electric air gun contains a main unit, an extension unit configured to a front end of the main unit, a detachable and adjustable butt unit configured to a rear edge of the main unit, and a cheek support unit that can be raised or lower along a top edge of the main unit. The extension unit can be telescoped out of the main unit and the butt unit can also be extended backward for different distance so as to suit users of various arm lengths. The cheek support unit on the other hand can be raised to various heights so that users of different neck lengths can more comfortably operate the electric air gun.
The foregoing objectives and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings. Throughout the specification and drawings identical reference numerals refer to identical or similar parts.
Many other advantages and features of the present invention will become manifest to those versed in the art upon making reference to the detailed description and the accompanying sheets of drawings in which a preferred structural embodiment incorporating the principles of the present invention is shown by way of illustrative example.
The following descriptions are exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.
As shown in
The extension unit 2 is for connection with the electric air gun, and contains a tubular body 21 with a number of positioning notches 211 along a bottom edge of the tubular body 21. The extension unit 2 is slidably plugged into the tubular section 11 of the main unit 1, and a bolt 22 runs through the positioning hole 16, the through hole 181, and into one of the positioning notches 211 so as to lock the extension unit 2. The extension unit 2 allows a user to adjust the buttstock's length so as to fit his/her arm length.
The second section 14 of the main unit 1 is plugged into the first section 13. The first and second sections 13 and 14 have positioning holes 19 and 144, and through openings 131 and 141, respectively. After the second section 14 is plugged into the first section 13, the positioning holes 19 and 144, and through openings 131 and 141 are aligned. Then the second section 14 is fixedly joined to the first section 13 by running fasteners 191 and 192 correspondingly through the positioning holes 19 and 144, and applying a bolt 193 to lock the fasteners 191 and 192. A laterally rotatable rotatory wheel 5 is configured in a space formed by the aligned openings 131 and 141.
The cheek support unit 3 contains a saddle-like cover 31, and a threaded shaft 313 beneath the cover 31. The cheek support unit 3 is joined to and covers the exposed middle segment 12 of the tubular section 11. The shaft 313 as such penetrates through a through hole 142 on a top side of the second section 14, into the opening 141, and axially through the rotatory wheel 5. As the rotatory wheel 5 is turned, the cover 31 is adjusted to move upward or downward. On two corresponding inner walls of the cover 31, there are a number of ribs 311 oppositely configured. As the cover 31 is moved, the ribs 311 engages two notches 121 along the exposed middle segment 12's two bottom edges so as to reliably position the cover 31. There are a pair of blocks 312 oppositely configured besides the ribs 311 on the two corresponding inner walls of the cover 31. Correspondingly, there are a pair of hooks 122 configured along the exposed middle segment 12's two top edges. The hooks 122 engage the blocks 312 so as to prevent the cover 31 from being moved too high.
As shown in
A threaded shaft 60 is threaded through the through hole 45, the buffer piece 421, and the rear cap 422, and a bolt 47 is joined to a rear end of the shaft 60. A front end of the shaft 60 runs axially through a vertically rotatable rotatory wheel 6 positioned in an indentation 143 along a rear side of the second section 14. By turning the rotatory wheel 6, the butt member 42 can be moved forward or backward so as to fit users of different arm lengths. The shaft 46 has a hook 461 on a front end and, as the butt member 42 is moved backward to an extent, the shaft 46 is moved backward as well and the hook 461 engages a limiting element 431 on an inner wall of the tubular element 43 so as to prevent the butt member 42 from being extended too much.
As described above, the extension unit 2 can be telescoped out of the main unit 1 and the butt member 42 can also be extended backward for different distance so as to suit users of various arm lengths. The cheek support unit 3 on the other hand can be raised to various heights so that users can more comfortably operate the electric air gun.
