Firearm Stock Integrated Cheek Riser Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing firearm cheek riser mechanisms are limited in adjustability due to their separate design from the firearm stock, which restricts the ability to achieve optimal eye centering and comfort during shooting.
Innovation Solution
An integrated firearm stock with an adjustable cheek riser mechanism that includes an elevation mechanism and a cheek plate attached to a rising mechanism, allowing for fine vertical adjustment of the cheek plate's height relative to the stock.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If cheek risers are designed as separate pieces attaching to the outside of the stock, then ease of manufacture is improved, but adjustability is limited
Solution Approach 1:
The cheek riser is integrated into the stock as a unified structure rather than a separate attachment. The stock body itself forms the cheek riser, eliminating the need for separate pieces that attach with straps, screws, or snaps. This integration provides unlimited adjustability along the length of the stock while maintaining ease of manufacture through single-piece construction.
Solution Approach 2:
The integrated stock design allows the cheek riser height to be dynamically adjusted by selecting different positions along the stock length, providing continuous adjustability rather than fixed positions. This enables the user to optimize eye centering and comfort for different shooting scenarios.
2Reliability
If typical cheek riser mechanisms use gears or locking mechanisms, then position stability is improved, but device complexity is increased
Solution Approach 1:
The patent removes complex gears, springs, and locking mechanisms from the cheek riser design. Instead, it uses a simple integrated structure where the cheek riser height is adjusted by selecting different positions along the stock length, eliminating the need for complicated position-locking mechanisms while maintaining position stability.
Solution Approach 2:
The integrated stock design allows the user to directly adjust the cheek riser height by positioning themselves at different locations along the stock, without requiring additional mechanisms to lock or secure the position. The stock structure itself provides the adjustment capability.

AI summary
A firearm stock system is described. The firearm stock system may comprise a stock, a firearm frame member positionally adjustable to the stock, a bottom plate disposed in connection with the stock, and a first rod rigidly connected with the bottom plate. The first rod axially may align to the bottom plate to the stock when the bottom plate is moved from a collapsed position to an expanded position or from an expanded position to a collapsed position The firearm stock may additionally comprise a second rod rigidly connected with the bottom plate and a guide block axially aligned with the second rod and a first spring axially aligned with one of the first rod or the second rod, the first spring configured to bias the bottom plate to the collapsed position.
