Cocking Slide Restoring Spring for Firearm Resetting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rifle lock clamping devices require manual resetting or rely on external influences, such as recoil force, which can be unreliable, especially after a weak charge or misfire, hindering quick follow-up shots.
Innovation Solution
A clamping device with a restoring spring that automatically returns the cocking slide to its uncocked position after a shot, independent of external influences, ensuring quick and reliable resetting without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cocking slide is reset manually or relies on external influences like recoil force, then the device structure remains simple, but the reliability of resetting is poor especially after weak charge or misfire
Solution Approach 1:
The cocking slide is equipped with its own restoring spring that automatically returns it to the uncocked position after firing, making the system self-resetting without relying on external factors like recoil force or manual intervention. This self-service mechanism ensures reliable resetting even after weak charges or misfires.
Solution Approach 2:
The restoring spring is pre-loaded and positioned to automatically act on the cocking slide immediately after the hammer is knocked off, ensuring the slide returns to its initial position without waiting for external influences. This preliminary action mechanism guarantees reliable resetting before the next shot can be fired.
2Productivity
If manual resetting is required after each shot, then the device structure remains simple, but the productivity for follow-up shots is reduced
Solution Approach 1:
The automatic resetting mechanism eliminates the need for manual intervention between shots. The restoring spring automatically returns the cocking slide to the uncocked position, allowing the shooter to immediately fire follow-up shots without having to manually reset the mechanism, thereby increasing productivity.
Solution Approach 2:
The restoring spring maintains continuous readiness to reset the cocking slide, ensuring that the firing mechanism is always prepared for the next shot. This continuous automatic resetting action eliminates interruptions and maintains operational flow, improving follow-up shot speed.
3Reliability
If the cocking slide relies on recoil force for resetting, then the device structure remains simple, but the reliability fails under weak charge or misfire conditions
Solution Approach 1:
The cocking slide has its own dedicated restoring spring that provides independent resetting capability, completely independent of the firing spring's energy or recoil force. This self-service mechanism ensures that even when the firing spring is weak or fails to ignite, the restoring spring can still reliably return the cocking slide to the uncocked position.
Solution Approach 2:
The restoring spring is pre-loaded and positioned to act immediately when the hammer is knocked off, ensuring reset action occurs before any potential weak charge effects. This preliminary action guarantees that the resetting function is independent of the firing charge strength, maintaining reliability under all conditions.
Applied Scientific Principles

Function Achieved in This Case
Enables automatic resetting of the cocking slide, allowing for quicker follow-up shots even with weak charges or misfires, enhancing operational reliability and efficiency.
Implementation Method 1
a return spring (42) acts on the cocking slide (6), by means of which the cocking slide (6) is automatically moved back into the uncocked position

AI summary
The device has a clamping slider (6) movably arranged at a closure housing (1). The clamping slider is connected with a clamping lever (7) for clamping and/or releasing a main spring (4) attached to a striking piece (2). The clamping slider has a rear resting unit for engaging in an anti-resting unit fixedly arranged at the closure housing for holding of the clamping slider in a clamping position. A reset spring i.e. compression spring (42) is engaged at the clamping slider such that the clamping slider is automatically moved back into a release position after striking of the striking piece.
