Abstract

An air gun including a trigger assembly, a gas spring assembly, and a latch assembly is disclosed. The trigger assembly is moveable between an uncocked position and a cocked position. The gas spring assembly includes a compression cylinder and a piston moveable between an uncompressed position and a compressed position. Movement of the piston from the uncompressed position into the compressed position couples the latch assembly to the trigger assembly and the piston of the gas spring assembly. The latch assembly includes a locking portion that mechanically interlocks with a recess disposed on an interior surface of the piston to couple the latch assembly and the piston together. Actuation of the trigger assembly de-couples the latch assembly from the trigger assembly, permitting longitudinal movement of the latch assembly, which de-couples the latch assembly from the piston of the gas spring assembly.

Dependent claims

An air gun comprising:

a trigger assembly moveable between a cocked position and an uncocked position;
a gas spring assembly including a compression cylinder and a piston slideably disposed about and moveable along a longitudinal axis relative to said compression cylinder between a compressed position and an uncompressed position, wherein said gas spring assembly is configured for compressing a gas within said compression cylinder in response to movement of said piston from said uncompressed position into said compressed position to load said gas spring assembly in preparation for firing a projectile when actuated by said trigger assembly;
and
a latch assembly moveable along said longitudinal axis relative to said trigger assembly and said gas spring assembly, said latch assembly including a first end and a second end spaced from said first end along said longitudinal axis with said first end releasably latched to said trigger assembly when said trigger assembly is in said cocked position and said first end de-latched from said trigger assembly when said trigger assembly is in said uncocked position, and said second end releasably latched to said piston of said gas spring assembly when said piston is in said compressed position and said second end de-latched from said piston of said gas spring assembly when said piston is in said uncompressed position.

A gas spring assembly for an air gun, said gas spring assembly comprising:

compression cylinder extending along a longitudinal axis;
a piston slideably disposed about and moveable along said longitudinal axis relative to said compression cylinder between a compressed position and an uncompressed position, wherein said compression cylinder and said piston are configured for compressing a gas within said compression cylinder in response to movement of said piston from said uncompressed position into said compressed position;
and
a latch assembly including a barrel portion concentric with said longitudinal axis, said latch assembly moveable along said longitudinal axis relative to said compression cylinder and said piston and including a first end and a second end spaced from said first end along said longitudinal axis with said second end releasably latched to said piston when said piston is in said compressed position and said second end de-latched from said piston when said piston is in said uncompressed position;
wherein said latch assembly includes a locking portion disposed adjacent said second end of said latch assembly, and wherein said piston includes a receiving end defining an aperture and an interior surface defining a recess adjacent said receiving end with said receiving end configured for receiving said locking portion therethrough and said recess configured for mechanically interlocking with said locking portion of said latch assembly when said piston is in said compressed position.
