Rotating Buttstock Bracket for Non-Orthogonal Firing Angles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional buffer tubes in firearms are not designed for non-orthogonal firing positions, leading to instability, inaccurate shots, and potential recoil-related injuries, as they require disassembly and reassembly to change the buttstock angle, which is impractical for field use.
Innovation Solution
A recoil mitigation and buttstock floating (RMBF) device with a rotating bracket system that allows the buttstock to be adjusted to multiple axial angles without disassembly, using a helical spring for recoil mitigation and secure locking mechanisms to maintain the desired position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional buffer tubes are used with fixed axial arrangement, then the firearm structure is simple and reliable, but the buttstock cannot be adjusted to non-orthogonal angles for firing under cover or in constrained positions
Solution Approach 1:
The buffer tube is designed with a rotating bracket mechanism that allows the buttstock to be dynamically adjusted between multiple axial angles (0°, 45°, 90°) relative to the firearm body. The bracket can rotate around the buffer tube while maintaining secure engagement through locking features, enabling the firearm to adapt to different firing positions without compromising structural integrity
Solution Approach 2:
The buffer tube assembly is divided into separable components including the rotating bracket, locking dowel pins, and the buttstock mounting interface. This segmentation allows independent adjustment of the buttstock angle while keeping the rest of the firearm assembly intact, providing versatility without requiring complete disassembly or complex integrated mechanisms
2Ease of operation
If locking dowel pins are used to secure the buttstock in desired positions, then the buttstock angle can be changed, but it becomes more difficult to quickly and easily switch between positions
Solution Approach 1:
The locking dowel pins are pre-positioned in the buffer tube at specific angular intervals (0°, 45°, 90°), and the rotating bracket is pre-configured with corresponding engagement features. This preliminary arrangement allows the user to quickly snap the bracket into the desired pre-prepared position without complex adjustment procedures or time-consuming assembly steps
Solution Approach 2:
The rotating bracket mechanism enables dynamic repositioning of the buttstock by allowing smooth rotation to different angular positions, with each position lockable via dowel pins. This dynamic capability allows rapid switching between firing angles without requiring disassembly, maintaining both ease of operation and structural security
3Adaptability or versatility
If the firearm is held at non-orthogonal angles for firing under cover, then the user can access targets in constrained positions, but the buttstock is not in proper shoulder location causing instability and inaccurate shots
Solution Approach 1:
The rotating bracket allows the buttstock to be dynamically repositioned to maintain proper alignment with the user's shoulder even when the firearm barrel is oriented at non-orthogonal angles. This dynamic adjustment capability ensures the buttstock remains stable and properly positioned relative to the shooter's body regardless of the firearm's axial orientation
Solution Approach 2:
The buffer tube assembly serves multiple functions: it maintains recoil mitigation, provides buttstock mounting, and enables angular adjustment for different firing positions. This multi-functionality allows the firearm to maintain stability and accuracy across various firing scenarios without requiring separate devices for each position
4Measurement precision
If multiple scopes are attached at different lines of sight offset from normal line of sight, then precision shots at different distances can be taken, but the firearm must be tilted which positions the buttstock in non-ideal position
Solution Approach 1:
The rotating bracket mechanism allows the user to dynamically adjust the buttstock angle to maintain proper shoulder positioning while the firearm is tilted for using different scopes. The bracket can be rotated to compensate for the tilt angle, ensuring the buttstock remains in an ideal position relative to the shooter's shoulder even when the barrel is oriented for long-range precision shooting

AI summary
A buffer tube for firearms, including assault rifles, carbines, shotguns, and other rifles is disclosed. The floating buffer tube comprises a recoil mitigation mechanism, including a helical spring or an elastic or viscous energy absorption device, and a buttstock mounting bracket mounted outside the buffer tube. The buttstock mounting bracket can rotate relative to the buffer tube, which changes the axial angle of the buttstock relative to the firearm. The angle can be locked under an expansive force by forcing a bolt or pin into grooves to select the proper axial angle of the buttstock relative to the firearm in the field without the user having to disarm himself to perform the angle change.
