Rifle Holder Hinge Assembly with 90-Degree Rotation Stops
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In range shooting, the organization of multiple weapons, especially larger rifles, in a small shooting stall is challenging due to space constraints, requiring unobtrusive and minimizable structures to manage weapon placement effectively.
Innovation Solution
A hinge assembly for rifle support comprising a hinge block with a sleeve and recess, a rotatable hinge pin, a support block with an indentation, and a rifle holder hook, limiting rotation to 90 degrees for compact storage and easy deployment, allowing the rifle holder hook to be positioned parallel or perpendicular to the mounting bracket.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rifle holder hook is provided to support rifles, then weapon storage capability is improved, but space occupation and clutter in the shooting stall increases
Solution Approach 1:
The rifle holder hook is designed with a hinge assembly that allows it to rotate between a horizontal storage position and a vertical support position. This dynamic capability enables the same structure to serve multiple functions: storing rifles horizontally when not in use, and providing vertical support when needed, thereby improving weapon storage capability without permanently occupying excessive space in the shooting stall.
Solution Approach 2:
The hinge assembly enables the rifle holder hook to change its spatial orientation from a horizontal plane to a vertical plane. By rotating the hook 90 degrees, rifles can be stored horizontally along the wall, utilizing wall space rather than floor space. This dimensional change allows efficient use of three-dimensional space in the shooting stall.
2Ease of operation
If the rifle holder hook is made adjustable and rotatable, then ease of operation for weapon alternation is improved, but device complexity increases
Solution Approach 1:
The hinge assembly is divided into distinct functional components: a hinge block with a recess, a hinge pin that rotates within the recess, and a rifle holder hook attached to the rotating element. This segmentation allows each component to perform its specific function simply - the hinge pin provides rotation, the hinge block provides structural support and positioning - while collectively achieving the complex goal of adjustable, rotatable weapon storage without requiring a complicated integrated mechanism.

AI summary
A rifle holder hinge mechanism comprising a support block with rifle hook attached thereto, the support block having a sleeve for receiving a hinge pin, and a hinge block, the hinge block having a hinge block sleeve, with a hinge pin rotatable within the hinge block sleeve. The support block further comprises a projection or detent, and the hinge block further comprise a cutaway or recess configured to receive the detent and limit rotation of the detent of the support block relative to the hinge block. Rotation may be limited 90 degrees such that the rifle holder hinge mechanism has a first position for receiving a weapon and a second position when it is not in use.
