The assist device includes a pushingrod 3 disposed within thesafety bolt 11 and movable forward or backward, a pushing-rod-resettingapparatus 4, and aprojection 31 on the pushingrod 3. Inside or adjacent to theslots 12 of thesafety bolt 11 is anopening 13 allowing theprojection 31 to extend therethrough. When the pushingrod 3 is pushed forward or backward, theprojection 31 extends through theopening 13 around theslots slots safety latch 2 is arranged beneath thesafety bolt 11. Aguide column 5 is disposed slantwise inside thesafety bolt 11, and a constrainingguide groove 32 is disposed on the central portion of the pushingrod 3 corresponding to theguide column 5. The combination of the constrainingguide groove 32 and theguide column 5 allows the pushingrod 3 to be connected to thesafety bolt 11 and to be movable forward or backward. The rear sidewall of theprojection 31 on the pushingrod 3 and the lower surface of theopening 13 are tapered guide edges matching each other.

As such, when the compressing handle 8 is opened or closed, the wedge-shapedpressing part 81 presses thesafety bolt 11 so as to deactivate the trigger safety. In other words, when the compressing handle 8 is opened to compress gas, it impacts thesafety bolt 11 via the contact of the tapered edges, which leads to automatic deactivation of the trigger safety. Specifically, the impact between the compressinghandle 8 and thesafety bolt 11 can be carried out by structures other than tapered edges and guide grooves. - The invention is described below in more details with references to the drawings.
- As shown in
FIG. 4 , the air gun is in a beginning state that the trigger safety is activated. In this state, thesafety latch 2 is fit in therear slot 12′ on the lower surface of thesafety bolt 11 so that the activation state of the trigger safety is locked. When the air gun is to be shot, as shown inFIG. 5 , the compressinghandle 8 is first opened for compressing gas. When the compressing handle 8 is opened, the wedge-shapedpressing part 81 on the rear end of the compressing handle 8 presses the front end of thesafety bolt 11 so that thesafety bolt 11 moves backward to deactivate the trigger safety and thesafety latch 2 is fit in thefront slot 12 to lock the deactivation state of the trigger safety. In other words, when the compressing handle 8 is opened to compress gas, it impacts thesafety bolt 11 via the contact of the tapered edge and exerts force on the upper and lower tapered edges of thesafety bolt 11 to push thesafety bolt 11 backward to automatically deactivate the trigger safety. Specifically, the impact between the compressinghandle 8 and thesafety bolt 11 can be carried out by structures other than a tapered edge or guide groove. When the compressing handle 8 compresses gas, in order to avoid accidental discharge of the air gun caused by unintentional pressure against thetrigger 9, as shown inFIG. 6 , thesafety apparatus 1 can be manually pushed forward to activate the trigger safety. When manually activating the trigger safety, the pushingrod 3 can be pushed first so that theprojection 31 thereon pushes thesafety latch 2 to the outside of therear slot 12′ and the deactivation state of the trigger safety is unlocked, and then thesafety bolt 11 is pushed to achieve activation of the trigger safety by a dramatically reduced force. After the gas is compressed and the compressing handle 8 is closed, the wedge-shapedpressing part 81 on the rear end of the compressing handle 8 pushes thesafety apparatus 1 to move backward to deactivate the trigger safety. After shooting, thesafety apparatus 1 can be manually pushed forward in the previously described manner to activate the trigger safety.FIG. 7 shows the activation of the trigger safety by closing thecompressing handle 8 and using the assist device. - While particular embodiments of the invention have been shown and described, it will be obvious to those skilled in the art that changes and modifications may be made without departing from the invention in its broader aspects, and therefore, the aim in the appended claims is to cover all such changes and modifications as fall within the true spirit and scope of the invention.
