Abstract

Break barrel airguns are provided with a loading system that uses the cocking action of the break barrel type airgun to load projectiles from a magazine held by a magazine holder into a shuttle system that is positioned by the magazine holder during loader and moved to a position aligned with the barrel during firing. The loading system has a resilient barrier between the magazine holder and the shuttle that reduces the risks of loading errors caused by adhesion between the bolt and a pellet.

First claim

What is claimed is:

1. An airgun comprising:
a tube fork having front face with a port from which a compressed gas can flow;
a barrel having 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 tube fork such that the barrel can be moved between a firing position where the opening is positioned to receive compressed gas and a cocking position;
a sled movable between a forward position and a retracted position;
a mechanism converting pivotal motion of the barrel relative to the fork into forces urging the sled to move toward the retracted position as the tube fork and the barrel move toward the firing position and into other forces that urge the sled to move toward the forward position as the tube fork and the barrel are rotated toward the cocking position;
a magazine holder adapted to position a magazine so that a bolt of the airgun passes through a first opening in the magazine holder, through the magazine to drive a projectile from the magazine, and through a second opening in the magazine holder as the bolt moves from the retracted position to the forward position;
a shuttle system adapted to move a projectile channel between a firing location sufficiently aligned with the barrel opening and the port to allow compressed air from the port to drive a projectile through the passageway and a loading location aligned with the second opening to allow the bolt to advance a projectile into the projectile channel; and
a resilient barrier provided at the second opening having a barrier opening with at least one opening flap portion that is configured with a resilient bias that is defined so that opening flap portion applies sufficient force against a portion of the pellet to overcome any adhesion between bolt and pellet as the bolt is moved from the forward position toward the retracted position so as to hold the pellet within the shuttle.

2. The airgun of claim 1 , wherein the opening flap portion is formed from a common resilient substrate with opening flap portion with the resilient bias of the resilient substrate providing the biasing force.

3. The airgun of claim 1 , wherein the bias of the opening flap portion is supplied by a spring.

4. The airgun of claim 1 , wherein the bolt has a tip portion with a width defined to engage a pellet generally along a back perimeter of a skirt of the pellet.

5. The airgun of claim 1 , wherein bolt is sized to engage pellet along the back perimeter of a skirt of a pellet to limit the extent of adhesion and by limiting the extent of the contact area between the bolt and skirt.

6. The airgun of claim 1 , wherein a plurality of opening flap portions is provided and arranged to create an inner diameter that is smaller than an outer diameter of a back perimeter of a pellet.
