first embodiment

Action: First Embodiment

[0106]FIG. 5 is a right side cutaway cross-section view of the airgun of FIG. 1 having a first embodiment of an action in a cocked state and a safety disengaged.

[0107]In the embodiment illustrated in FIG. 5, action 70 has a fire control mechanism 76, a safety 80 and a trigger 100. Fire control mechanism 76 interacts with hammer system 60 to prevent hammer 64 from moving from the cocked position shown in FIG. 1 unless a user has moved safety 80 from an engaged position shown in FIG. 1 to a disengaged position as shown in FIG. 2 and further moves trigger 100 from a first trigger position shown in FIG. 1 to a second trigger position shown in FIG. 5.

[0108]The operation of the embodiment of action 70 of FIG. 1, will now be described in greater detail with respect to FIGS. 5-10.

[0109]FIG. 5 shows a right side view of hammer system 60 and action 70 of FIG. 1 in a cocked state with other portions of airgun 10 cut away.

[0110]As is shown in FIG. 5, in this embodiment, ...

second embodiment

Action: Second Embodiment

[0165]FIG. 12 is a right side view of another embodiment of action 70 with a portion of secondary sear 140 removed and a secondary sear spring removed to better illustrate the concepts described while FIG. 13, is a front, right, top perspective view of the embodiment of action 70 of FIG. 12.

[0166]In this embodiment, a trigger 100 is mounted about a trigger pivot 104 and is joined to a first end 117 of lift 116 by a trigger lift pivot 118.

[0167]A trigger return spring 111 is also mounted about trigger pivot 104. Trigger return spring 111 has a primary sear bias leg 113 and a second spring a trigger reset contact leg 115 that urges lift 116 to rotate about trigger lift pivot 118 in a direction that brings a first lift end 121 into contact with a trigger stop 108. When first lift end 121 is in contact with trigger stop 192, such urging then serves to urge trigger 100 away from the fired position.

[0168]In this embodiment, and as is generally described above, pri...

Abstract

Airguns are provided with semi-automatic action.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]N / ASTATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT[0002]N / AREFERENCE TO SEQUENCE LISTING, A TABLE, OR A COMPUTER PROGRAM LISTING COMPACT DISC APPENDIX[0003]N / AFIELD OF THE INVENTION[0004]This invention relates to airguns having actions capable of semi-automatic fire.BACKGROUND OF THE INVENTION[0005]Airguns are known that can provide semi-automatic action. In some cases, a revolver type action is used, where the force of the trigger pull advances one of a pluarlity of preloaded cylinders into a position for firing and cocks the hammer for firing. One example of this is U.S. Pat. No. 5,285,766 entitled “Gun with Removable Rotary Ammunition Clip” filed by Milliman on Jul. 30, 1992.[0006]Other airguns secure semi-automatic action by diverting propellant such as pressurized gas from a supply that to propel ammunition to operate the action.[0007]Still other airguns attempt to recycle used pressurized propellant gas for the purpos...
