Firearm Riser With Elastic Hooks For Rail Variance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing firearm accessory mounting systems on accessory rails, such as Weaver or Picatinny rails, face challenges in achieving sufficient height adjustment and accommodating dimensional variances in rail configurations, leading to limitations in spacing accessories from the rail.
Innovation Solution
A quarter-inch riser with two sections, each having a body with fastener holes and recoil lugs with hooks that can elastically deform, allowing for adjustable positioning and compatibility with various rail dimensions, enabling a quarter-inch increase in accessory spacing from the rail.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional rigid riser is used to space an accessory from the rail, then the accessory spacing is fixed, but the ability to accommodate dimensional variances in different rail configurations is poor
Solution Approach 1:
The riser is divided into multiple sections (first section and second section) that can be positioned at different heights relative to the rail. Each section has its own clamping mechanism, allowing independent adjustment and accommodation of rail dimensional variances while maintaining overall structural integrity.
Solution Approach 2:
The riser incorporates elastic elements (springs) that allow dynamic adjustment and compression to accommodate dimensional variances in rail configurations. The elastic elements enable the rigid riser structure to adapt to different rail heights and tolerances while maintaining secure attachment.
2Adaptability or versatility
If the riser is made fully elastic to accommodate rail variances, then compatibility improves, but the structural strength and stability decrease
Solution Approach 1:
The riser is segmented into rigid sections connected by elastic elements. The rigid sections maintain structural strength and stability, while the elastic elements provide the necessary flexibility and adaptability to accommodate rail dimensional variances.
Solution Approach 2:
Different parts of the riser have different mechanical properties - the sections are rigid for strength, while the connecting elements are elastic for adaptability. This local differentiation of material properties allows the structure to simultaneously achieve strength and flexibility where needed.
3Ease of manufacture
If a one-piece riser design is used, then manufacturing is simple, but height adjustment and positioning flexibility are limited
Solution Approach 1:
The riser is designed as multiple sections that can be manufactured separately using standard machining processes, then assembled together. This segmentation allows for height adjustment by selecting different section combinations while keeping individual component manufacturing relatively simple.
Solution Approach 2:
The riser sections are designed with standardized interfaces and features that allow them to be used in multiple configurations and positions. The same basic section design can be reused in different combinations to achieve various height adjustments, reducing the number of unique parts needed.

AI summary
A riser for spacing a firearms accessory from a firearms accessory rail has a body, at least a portion of the body having approximately the same cross-sectional shape and slot configuration as a mounting portion of the accessory rail, at least one lug depending from the body and extending laterally, the lug being adapted for insertion into a slot of the accessory rail, and a hook adapted for coupling the riser to the accessory rail, the hook extending from a lateral end of the lug. At least a portion of the hook is adapted to be longitudinally aligned with the slot of the accessory rail and adapted to engage the accessory rail by contacting the accessory rail below the associated slot of the accessory rail.
