Sliding Symmetrical Rifle Cheekpiece With Adjustable Buttstock Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cheekpieces for hunting and sporting rifles are asymmetrical, difficult to handle, require high locking forces, and lack height adjustment, making them unsuitable for both left- and right-handed shooters.
Innovation Solution
A symmetrical, U-shaped cheekpiece that can be slid onto the buttstock from the rear and locked in a height-adjustable position, using spring-loaded push buttons for secure attachment with minimal force, allowing easy switching between left- and right-handed use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an asymmetrical cheekpiece is attached to the buttstock, then secure attachment is achieved, but handling becomes difficult and it is unsuitable for both left- and right-handed shooters
Solution Approach 1:
The cheekpiece is designed with a symmetrical U-shaped profile that can be mounted on either side of the buttstock, making it suitable for both left- and right-handed shooters while maintaining secure attachment through complementary profiles
2Reliability
If a cheekpiece is attached from above to the buttstock, then secure fit is achieved, but high locking forces are required making it difficult to handle
Solution Approach 1:
Instead of attaching the cheekpiece from above to the buttstock, the invention inverts the attachment direction by sliding the cheekpiece onto the buttstock from the rear in the direction of fire, which reduces the required locking forces while maintaining secure fit
3Adaptability or versatility
If a symmetrical cheekpiece is designed for both left- and right-handed shooters, then versatility is improved, but strong springs are required to prevent play increasing attachment force
Solution Approach 1:
The invention changes the design parameters by using a symmetrical U-shaped profile with complementary profiles that engage without requiring strong springs, allowing versatile use by both left- and right-handed shooters while reducing attachment force requirements
4Adaptability or versatility
If height adjustment is added to the cheekpiece, then adaptability is improved, but device complexity increases
Solution Approach 1:
The cheekpiece is designed with a segmented structure featuring multiple notches on its underside that engage with corresponding protrusions on the buttstock, enabling height adjustment through simple discrete positions without complex mechanisms
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables secure, one-handed attachment and adjustment of the cheekpiece, reducing handling difficulties and accommodating both left- and right-handed shooters without the need for complex assembly or high locking forces.
Implementation Method 1
spring-loaded push buttons for secure attachment with minimal force

AI summary
Hunting or sporting firearm with an approximately symmetrical, roughly U-shaped profiled cheekpiece (3) arranged on a buttstock (5) of the firearm, the outer surface of which is suitable as a cheek rest (39) for the shooter's face, wherein a profile is arranged on the inner sides of the U-shaped legs of the cheekpiece which can engage with a complementary profile on the side surfaces of the buttstock (5), wherein the cheekpiece (3) can be slid onto the buttstock (5) and locked in the use position on the buttstock (5).
