This invention pertains generally to an air distribution device for a dual barrel air gun that enables the user to selectively route the compressed air or other gases that are used to propel a BB, pellet or other projectile to either barrel of the dual barrel air gun.
Many air gun enthusiasts enjoy firing air guns. An air gun fires a projectile such as a pellet or a BB using a compressed air or other gas, and a dual barrel air gun has two barrels, each of which is capable of discharging said BB or pellet.
Heretofore, a user of a dual barrel air gun had to pull the trigger of the air gun to discharge a blast of air or other gas through both barrels (see e.g., U.S. Pat. No. 9,200,866), or had to choose a specific trigger to fire from a desired barrel of the air gun (see e.g., U.S. Pat. No. 2,196,732). Neither of said options is particularly appealing to air gun enthusiasts because neither of said options permit a user to selectively fire from one barrel of said air gun with a single trigger.
Consequently, there exists a long felt need in the art for an air distribution device for a dual barrel air gun that enables a user to selectively route the air or other gas to either barrel of the dual barrel air gun with a single trigger. There is also a long felt need in the art for an air distribution device that enables the user to reduce the time between follow up shots. Finally, there is a long felt need in the art for a device that accomplishes all of the forgoing objectives, and that is relatively inexpensive to manufacture and safe and easy to use.
The following presents a simplified summary in order to provide a basic understanding of some aspects of the disclosed innovation. This summary is not an extensive overview, and it is not intended to identify key/critical elements or to delineate the scope thereof. Its sole purpose is to present some concepts in a simplified form as a prelude to the more detailed description that is presented later.
The subject matter disclosed and claimed herein, in one aspect thereof, comprises an air distribution technique and device for a dual barrel air gun, wherein said air distribution device is preferably comprised of: a body portion; a selector stem with a plurality of openings therein; a first transfer port that is capable of aligning with one of said openings so that a blast of air or other gas is capable of passing from said selector stem through said first transfer port; and a second transfer port that is capable of aligning with a different at least one of said plurality of openings so that a blast of air is capable of passing from said selector stem through said second transfer port.
To the accomplishment of the foregoing and related ends, certain illustrative aspects of the disclosed innovation are described herein in connection with the following description and the annexed drawings. These aspects are indicative, however, of but a few of the various ways in which the principles disclosed herein can be employed and is intended to include all such aspects and their equivalents. Other advantages and novel features will become apparent from the following detailed description when considered in conjunction with the drawings.
The innovation is now described with reference to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding thereof. It may be evident, however, that the innovation can be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to facilitate a description thereof.
The present invention is directed to an air distribution technique and device for a dual barrel air gun. Turning now to the drawings,
As best shown in
As best illustrated in
In a preferred embodiment of the present invention, selector stem 120 further comprises a handle 125 and a chock 127, as best shown in
Selector stem 120 is generally restricted from axial (longitudinal) movement by a retainer 172. Retainer 172 is installed in a groove 174 in stem selector 120, preferably near second end 126. In this manner, movement of stem selector 120 is generally limited to partial rotation around its longitudinal axis to allow alignment between corresponding openings 1242, 1244, transfer ports 140, 160 and ultimately barrels 16, 18. More specifically, chock 127 extends outwardly from and partially around the exterior surface of body 124 in the general vicinity of handle 125. As best shown in
First transfer port 140 is preferably a generally cylindrical, elongated member comprised of a first threaded insert 142 for mating with first port opening 117, a first barrel insert 144 for insertion into an end of first barrel 16, and a continuous opening 146 that extends longitudinally through first transfer port 140, thereby providing a possible air passageway between device 100 and first barrel 16. First barrel insert 144 may further comprise a circumferential groove 1440 therein for receipt of O-ring 170, as best shown in
Second transfer port 160 is preferably substantially similar in size, shape and function as first transfer port 140 and is comprised of a second threaded insert 162 for mating with second port opening 118, a second barrel insert 164 for insertion into an end of second barrel 18, and a continuous opening 166 that extends longitudinally through second transfer port 160, thereby providing a possible air passageway between device 100 and second barrel 18. Second barrel insert 164 may further comprise a circumferential groove 1640 therein for receipt of O-ring 170, as best shown in
Having described the structure of air distribution device 100, its use will now be generally described. A user (not shown) desiring to, for example, discharge a projectile (not shown) from the first barrel 16 of dual barrel air gun 10 will simply rotate selector stem 120 until the “R” marking on handle 125 (or second handle 1251) is facing user (who would be positioned immediately adjacent to stock 12 of dual air gun 10) and pin 180 prevents chock 127 and selector stem 120 from further rotating in the initial direction. When the “R” (or other indicia) is in this particular position, first continuous opening 1242 in selector stem 120 is aligned and in air communication with first transfer port 140 and allows the air or other gas (not shown) to be discharged from an air gun tank (not shown) through first continuous opening 1242 in selector stem 120, first transfer port 140 and into first barrel 16 which, in turn, propels a load (e.g., a BB, pellet, arrow or some other projectile) through first barrel 16 and towards its intended target.
The user can then immediately rotate handle 125 (or second handle 1251) in the opposite direction until the “L” marking is facing user (who would still be positioned immediately adjacent to stock 12 of dual air gun 10) and pin 180 prevents chock 127 and selector stem 120 from further rotating. When the “L” is in this particular position, second continuous opening 1244 in selector stem 120 is aligned and in air communication with second transfer port 160 and allows the air or other gas (not shown) to be discharged from an air gun tank (not shown) through second continuous opening 1244 in selector stem 120, second transfer port 160 and into second barrel 18 which, in turn, propels the load or projectile through second barrel 18 and towards its intended target. As an important aspect of the present invention, it is worth noting that when first continuous opening 1242 in selector stem 120 is aligned and in air communication with first transfer port 140, second continuous opening 1244 in selector stem 120 is not aligned nor is it in air communication with second transfer port 160, and vice versa, so that compressed air or other gasses are not discharged through the unselected barrel.
The alternative embodiments of the present invention will function in a substantially similar manner as described above, except that the embodiment depicted in FIGS. 7A and 7B also offers the user the ability to rotate stem selector 120 from either side of device 100 (which users that are right handed or left handed can appreciate) and the device 100 depicted in
What has been described above includes examples of the claimed subject matter. It is, of course, not possible to describe every conceivable combination of components or methodologies for purposes of describing the claimed subject matter, but one of ordinary skill in the art may recognize that many further combinations and permutations of the claimed subject matter are possible. Accordingly, the claimed subject matter is intended to embrace all such alterations, modifications and variations that fall within the spirit and scope of the appended claims. Furthermore, to the extent that the term “includes” is used in either the detailed description or the claims, such term is intended to be inclusive in a manner similar to the term “comprising” as “comprising” is interpreted when employed as a transitional word in a claim.
