Abstract
A safety pin locks a barrel latch while the firearm discharges a round of ammunition. The barrel latch safety locking mechanism is incorporated into the frame and is actuated by the trigger assembly. The barrel latch safety locking mechanism engages the barrel latch to prevent movement during firing keeping the barrel latch engaged with the barrel. The firearm is further comprised of a slide switch that is connected to the barrel latch that allows a user to disengage the barrel latch for loading.
Claims20
A firearm, comprising:
- a frame comprising a barrel latch safety locking mechanism and a mount, wherein the barrel latch safety locking mechanism comprises a barrel latch having a notch, a locking pin positioned outside the notch in a first configuration and positioned at least partially within the notch in a second configuration, and a spring;
- a firing assembly situated within the frame;
- a barrel assembly comprising a barrel and a catch connected to the barrel, wherein a first section of the barrel assembly is pivotally connected to the frame through the mount and a second section of the barrel assembly is releasably connected to the frame through the catch, wherein the barrel assembly rotates around the mount between an open loading orientation and a closed firing orientation, and wherein the barrel latch engages the catch when the barrel is in the closed firing orientation;
- and
- a trigger assembly operatively connected to the frame and the firing assembly, wherein the trigger assembly comprises a trigger pull having a rest position and a retracted position, wherein the trigger pull moves the locking pin from the first configuration outside the notch to the second configuration within the notch as the trigger pull is actuated from the rest position to the retracted position, and wherein the spring biases the locking pin out of the notch toward the top side of the trigger pull.

A firearm, comprising:
- a frame comprising a barrel latch safety locking mechanism and a mount, wherein the barrel latch safety locking mechanism comprises a barrel latch having a notch and a locking pin positioned outside the notch in a first configuration and is positioned at least partially within the notch in a second configuration;
- a firing assembly situated within the frame;
- a barrel assembly comprising a barrel and a catch connected to the barrel, wherein a first section of the barrel assembly is pivotally connected to the frame through the mount and a second section of the barrel assembly is releasably connected to the frame through the catch, wherein the barrel assembly rotates around the mount between an open loading orientation and a closed firing orientation, and wherein the barrel latch engages the catch when the barrel is in the closed firing orientation;
- and
- a trigger assembly operatively connected to the frame and the firing assembly, wherein the trigger assembly comprises a trigger pull and a ramp on a top side of the trigger pull, wherein the trigger pull has a rest position and a retracted position, wherein the ramp is aligned with the notch when the trigger pull is in the rest position, and wherein the ramp pushes the locking pin from the first configuration outside the notch to the second configuration within the notch as the trigger pull is actuated from the rest position to the retracted position.

A firearm, comprising:
- a frame comprising a barrel latch safety locking mechanism and a mount, wherein the barrel latch safety locking mechanism comprises a barrel latch, a locking pin, a leaf spring, a coil spring, and a slide switch, wherein the barrel latch has a notch and the locking pin is positioned outside the notch in a first configuration and is positioned at least partially within the notch in a second configuration;
- a firing assembly situated within the frame;
- a barrel assembly comprising a barrel and a catch connected to the barrel, wherein a first section of the barrel assembly is pivotally connected to the frame through the mount and a second section of the barrel assembly is releasably connected to the frame through the catch, wherein the barrel assembly rotates around the mount between an open loading orientation and a closed firing orientation, wherein the barrel latch engages the catch when the barrel is in the closed firing orientation, wherein the coil spring biases the barrel latch into engagement with the catch on the barrel, wherein the slide switch is biased by the coil spring to a first position corresponding with the barrel latch being in engagement with the catch, wherein the slide switch is actuated to a second position when the locking pin is disengaged from the notch in the first configuration, and wherein the slide switch disengages the barrel latch from the catch when in the second position;
- and
- a trigger assembly operatively connected to the frame and the firing assembly, wherein the trigger assembly comprises a trigger pull having a rest position and a retracted position, and wherein the trigger pull moves the locking pin from the first configuration outside the notch to the second configuration within the notch as the trigger pull is actuated from the rest position to the retracted position.
