Adjustable Cheek Riser for Rifles via Clamshell Hinge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current rifles for sport shooting either lack adjustability or require expensive modifications to add customizable features, limiting user performance and fit.
Innovation Solution
A cheek riser system with a shell and adjustable cheek rest that can be attached to a rifle stock without modifying the stock, featuring a stud aperture and clamshell hinge design for secure and adjustable fit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If modifications are made to the rifle stock (cutting and drilling holes), then adjustability and customization options are improved, but the complexity of manufacture and difficulty of installation increase
Solution Approach 1:
The patent introduces a mounting rail system as an intermediary component that attaches to the rifle stock without requiring modifications. The rail serves as a mediator between the stock and accessories, providing mounting capabilities through adhesive attachment rather than permanent modification, thereby resolving the contradiction between adaptability and ease of manufacture
Solution Approach 2:
The invention extracts the adjustability function from the rifle stock itself and relocates it to removable accessories that attach to the mounting rail. This allows the stock to remain unmodified while still providing full adjustability through detachable components, resolving the contradiction between adaptability and ease of manufacture
2Adaptability or versatility
If expensive replacement stocks are purchased, then adjustability and customization options are improved, but the cost increases
Solution Approach 1:
The patent segments the customization system into separate components: a base mounting rail and individual adjustable accessories. This allows users to purchase only the rail once and then add only the specific accessories needed, rather than purchasing an entirely expensive replacement stock, resolving the contradiction between customization options and cost
Solution Approach 2:
The mounting rail provides universal functionality by supporting multiple types of accessories at various positions. A single rail installation enables diverse customization options including cheek rests, lights, and other accessories, eliminating the need for expensive specialized stocks and resolving the contradiction between customization options and cost
3Ease of operation
If the cheek rest is made adjustable, then user fit and performance are improved, but the device complexity increases
Solution Approach 1:
The patent implements a dynamic adjustment mechanism where the cheek rest can be vertically positioned at multiple heights along the mounting rail. This dynamic adjustability allows users to achieve optimal fit and performance while the modular design keeps the adjustment mechanism simple and intuitive, resolving the contradiction between ease of operation and device complexity

AI summary
Cheek risers for rifles have a shell configured to closely receive at least a portion of the tapered butt, the shell defining a stud aperture configured to receive the stud when the shell closely receives the butt, and an adjustable cheek rest connected to the shell and operable for vertical position adjustment with respect to the shell. The stud aperture may be circular. The stud aperture may be configured to closely receive a sling stud. The shell may have an upper portion and a lower portion selectably and removably connected to each other. The upper portion and lower portion may be unitary and connected via a live hinge. The upper portion and lower portion may include a separable hinge interface on one side, and a connection facility on an opposed side. The separable hinge interface may include a pin element and a hook element configured to engage the pin element.
