Gun Stock Adjustable Comb via Button Stop Pin
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gun stocks with adjustable combs require complex and time-consuming operations to adjust the cheek rest, which is undesirable in unpredictable hunting conditions.
Innovation Solution
A gun stock with an integrated adjustable comb system that allows for quick and simple height adjustment of the cheek rest using a button-activated stop pin mechanism, eliminating the need for tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional tools and complex adjustment systems are used to adjust the comb, then the comb can be adjusted to precise positions, but the adjustment operation becomes complex and time consuming
Solution Approach 1:
The adjustment mechanism is designed to be self-servicing through a button-activated stop pin system that allows the user to adjust the comb position without requiring external tools. The button releases the stop pin to allow movement, and releasing the button engages the stop pin to fix the position, making the system self-contained and tool-free.
Solution Approach 2:
The adjustment mechanism is divided into discrete functional elements: a button for activation, a stop pin for positioning, and teeth for engagement. This segmentation allows each component to perform its specific function independently, simplifying the overall operation while maintaining precision.
2Ease of operation
If traditional adjustment systems are used, then the comb can be adjusted, but the operation is time consuming
Solution Approach 1:
The button-activated mechanism allows immediate adjustment without requiring tool retrieval or complex manual manipulation. The user simply presses the button to release the stop pin, adjusts the comb to the desired position, then releases the button to engage the stop pin, completing the adjustment in seconds.
Solution Approach 2:
The stop pin is pre-positioned and ready to engage with the teeth at predetermined locations. This preliminary positioning allows for rapid adjustment to specific positions without requiring measurement or alignment procedures during the adjustment operation.
3Ease of operation
If integrated adjustment mechanisms are used, then adjustment becomes simpler, but manufacturing costs may increase
Solution Approach 1:
The mechanism is segmented into separate, manufacturable components (button, stop pin, teeth) that can be produced using standard manufacturing processes and then assembled. This segmentation simplifies manufacturing compared to creating a monolithic integrated mechanism, while still providing tool-free adjustment capability.

AI summary
Gun stock with adjustable comb includes a stock body having an adjustable comb which comprises a cheek rest member associated to a supporting structure associated to the stock body; the supporting structure has a hollow guide body slidable along a pin associated to the stock body; the guide body is slidable with respect to the pin in contrast to an elastic member; the guide body is engaged by a drive means that has a button accessible from the outside of the stock body; the height of the comb with respect to the stock body is adjusted by acting on the button for the engagement and disengagement of the guide body with respect to the pin integral with the stock body.
