The examples used herein are intended merely to facilitate an understanding of ways in which the present disclosure may be practiced and to further enable those of ordinary skill in the art to practice the embodiments of the present disclosure. Accordingly, the examples and embodiments herein should not be construed as limiting the scope of the present disclosure, which is defined solely by the appended claims and applicable law.

Generally, this disclosure describes embodiments of a puncture mechanismto puncture a pressurized gas cartridgefor a projectile launcher.

Referring now to the figures, and initially to, there are shown various embodiments of a launcherfor a projectile. In one embodiment, the launcherhas a handleconnected to a frame. Within the frameis a barreland a cartridgethat contains high pressure gas to provide the propellant to accelerate a boltto fire a projectilefrom the barrelof the launcher. The high pressure gas is retained within the cartridgeuntil a puncture mechanismpunctures a sealon the cartridgeto release the gas. The launcher also has a triggerto initiate the process for firing the projectile, and a trigger guard. In the various embodiments shown, the puncture mechanismhas a trigger guardthat is used to initiate the process for releasing the high pressure gas from the cartridgethat is transferred from the cartridgethrough pipingto an air chamberto provide the propellant for ultimately propelling the bolttoward the opening in the barrelto fire the projectile.

Referring to, in one embodiment, the cartridgecontaining the high pressure gas is located within the frameof the launcher. The cartridgemay be inserted into a cartridge openingand fixed into position the framewith a cartridge holder. The cartridgehas a sealat the opening thereof that retains the high pressure gas within the cavityof the cartridge.

In one embodiment, as shown in, the trigger guardis slidingly connected to the launcher. The trigger guardhas a first endthat slidingly engages the frame, and a second endthat slidingly engages the handle. In one embodiment, a male member, such as a shaft, extends from the first endof the trigger guard, and slidingly mates with an opening, such as a bore, in the frame. Further, in one embodiment, a male memberextends from the handleto slidingly engage a female receiverat the second endof the trigger guard. The reverse structure at either the first endand/or the second endof the trigger guard, however, may also be utilized. Further, other mating structural members may be utilized in place of the male/female relationship shown in the figures. This sliding engagement of the trigger guardwith the launcherallows the trigger guardto move from a first normal or unactuated position, as shown in, to a second actuated position, as shown in. Following movement of the trigger guardto the actuated position of, once a force from the user on the trigger guardis released, a bias member, such as a spring, forces the trigger guardback to the unactuated positon as shown invia engagement of the trigger guardwith a pivot armas described herein.

As best shown in, in one embodiment, the puncture mechanismgenerally comprises the trigger guard, a pivot arm, a puncture needleand a bias member. Between the first endand the second endof the trigger guard, the trigger guardhas a trackto receive a followerof the pivot arm. In one embodiment the trackis linear and is open to the trigger area, however the trackmay have side railsto assist in slidingly retaining the pivot armwithin the trackas the trigger guardmoves from the normal position to the actuated position, and then back to the normal position.

In one embodiment, the pivot armcomprises a follower armhaving a follower, an engagement armand a pivot member. In one embodiment the follower armis on one side of the pivot member, and the engagement armis on the other side of the pivot member. The pivot membermay comprise a shaftthat engages a receiverin the frameand which allows the pivot armto pivot about the pivot member. The followermay comprise at least one cam follower such as roller members. In one embodiment, the roller membersare rotationally connected to the follower armand are retained in the trackby the side rails, but allowed to move linearly within the trackfrom a first position as shown in, wherein the pivot armis also in its first position and wherein the trigger memberis in the normal position, to a second position as shown in, wherein the pivot armis also in its second position and wherein the trigger guardis in the actuated position. Further, the roller membersare retained within the trackas the pivot armand roller membersreturn from the second position to the first position, and as the trigger guardreturns from the actuated position to the normal position, as shown in.

Moving the trigger guardfrom the normal position to the actuated position (i.e., from the position shown into the position shown in) causes the pivot armto pivot about its pivot memberto its second position to move the puncture needle. As shown in, in one embodiment, the puncture needlehas a first endand a second end. The first endhas a borewith an openingthat is in fluid communication with an air passage. In the second position of the pivot arm, the engagement armpushes on the second endof the puncture needleto linearly move the puncture needlefrom having its first endbeing adjacent but outside the sealof the cartridge, to piercing the sealand placing the first endof the puncture needlewithin the cavityof the cartridge. Thus, as is shown, the puncture needlemoves linearly within a borefrom a first position, shown in, to a second position, shown in. When the first endof the puncture needlehas pierced the sealand is within the cavityof the cartridge, the high pressure gas within the cartridge can flow through the borein the puncture needleand into the air passage. Once the puncture needleis moved to the second position whereby the first endof the puncture needleis within the cavityof the cartridge, the puncture needlegenerally stays in that position even though the pivot armpivots back to its first position and is no longer engaged with the puncture needle. The high pressure air generally flows through the boreand the air passage, and into the pipingshown into the air chamberfor providing propellant for firing the projectile.

Once the user releases the trigger guard, the bias memberforces the pivot memberfrom its second position, shown in, to its first position, shown in. And, simultaneously, as the pivot membermoves from the second position to the first position, it moves the trigger guardfrom the actuated position shown into the normal position shown in.
