Abstract
Break barrel airguns are provided with a loading system that uses the cocking action of the break barrel type airgun to charge an energy storing device. A rotary style magazine is provided that enables multi-shot capability for the airgun. The magazin is held by a magazine holder and engages with engagement components that reduce backlash, prevent backwards rotation of the magazine, and ensure alignment of the projectile holders in the magazine with the opening of the barrel.
Claims19
An airgun comprising:
- a breech comprising a first face with a port from which a compressed gas can flow;
- a barrel defining a passageway through the barrel with an opening at a back barrel face with the passageway sized to receive a projectile;
- a pivot joining the barrel to the breech such that the barrel can be moved between a firing position where the opening is positioned to receive the compressed gas and a cocking position;
- a rotary magazine comprising:
- a turret comprising a plurality of projectile holders arranged around a central axis of the turret;
- a center channel positioned at the central axis of the turret, the turret configured to rotate around the center channel;
- and
- a first engagement component positioned around the center channel, the first engagement component configured to reduce backlash and prevent backwards rotation of the turret;
- and
- a magazine holder adapted to position a projectile holder of the plurality of projectile holders in alignment with the passageway, the magazine holder comprising:
- an arbor;
- a spring;
- and
- a second engagement component coupled to the arbor and biased into contact with the rotary magazine by the spring, the second engagement component configured to interface with the first engagement component, wherein:
- the first engagement component and the second engagement component are configured to cause lateral movement of the rotary magazine as the rotary magazine rotates;
- the first engagement component and second engagement component enable rotation in a first direction and limit rotation in a second direction opposite the first direction;
- and
- the first engagement component and the second engagement component are further configured to interface to bias rotation of the turret such that the plurality of projectile holders are aligned with the passageway.

An airgun comprising:
- a barrel defining a passageway;
- an energy storage and release device;
- a breech comprising:
- a first breech surface comprising an opening connected with the passageway of the barrel;
- a second breech surface comprising a conduit connected with the energy storage and release device;
- a rotary magazine comprising:
- a turret comprising a cylindrical body defining a plurality of projectile holders;
- an pivot location positioned at a center of the turret;
- and
- a first engagement component positioned around the pivot location, the first engagement component configured to reduce backlash and resist backwards rotation of the turret;
- and
- a magazine holder adapted to position a projectile holder of the rotary magazine in alignment with the passageway, the magazine holder comprising:
- an arbor providing a pivotal axis for the turret;
- a spring;
- and
- a second engagement component coupled to the arbor and biased into contact with the rotary magazine by the spring, the second engagement component configured to interface with the first engagement component, wherein the first engagement component and the second engagement component are configured to cause lateral movement of the rotary magazine as the rotary magazine rotates and the first engagement component and second engagement component enable rotation in a first direction and limit rotation in a second direction opposite the first direction.

A magazine system for a multi-shot airgun comprising:
- a magazine body comprising:
- a first breech surface defining a first passageway configured to align with a barrel of the multi-shot airgun;
- a second breech surface disposed on an opposite side of the magazine body from the first breech surface and defining a second passageway to an air reservoir;
- a rotary turret comprising:
- a cylindrical body defining a plurality of projectile holders;
- an pivot location positioned at a center of the turret;
- and
- a first engagement component positioned around the pivot location, the first engagement component configured to reduce backlash and resist backwards rotation of the turret;
- and
- a magazine holder comprising:
- an arbor providing a pivotal axis for the turret;
- a spring;
- and
- a second engagement component coupled to the arbor and biased into contact with the rotary turret by the spring, the second engagement component configured to interface with the first engagement component, wherein:
- the first engagement component and the second engagement component are configured to cause lateral movement of the rotary magazine as the rotary magazine rotates;
- the first engagement component and second engagement component enable rotation in a first direction and limit rotation in a second direction opposite the first direction;
- and
- the first engagement component and the second engagement component are further configured to interface to bias rotation of the turret such that the plurality of projectile holders are aligned with the passageway.
