Weapon Rail Mounting Device with Camming Lock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting devices for accessories on weapons, such as rifles, face limitations in securely attaching and adjusting accessories to receiver rails, particularly in maintaining a secure grip and preventing loosening due to vibration.
Innovation Solution
A mounting device with a base portion and movable side portions that cooperate to selectively grip a weapon's rail, utilizing an elongated connecting member and camming device with a lever and locking mechanism to securely attach and detach accessories, featuring a camming device with a lever that moves between open and closed positions, and a locking mechanism with a latch or spring to maintain the closed position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mounting device uses a camming device with lever to grip the rail, then the gripping force and stability are improved, but the device complexity increases
Solution Approach 1:
The mounting device is divided into distinct functional segments: a base portion, movable side portions, a camming device with lever, and a locking mechanism. Each segment performs a specific function, allowing the complex gripping action to be broken down into manageable components that can be independently optimized and assembled.
Solution Approach 2:
The mounting device incorporates movable side portions that can dynamically adjust their position relative to the rail. The camming device with lever provides dynamic gripping force that can be applied and released, allowing the device to adapt to different rail configurations and maintain secure engagement through controlled movement rather than static fixation.
2Reliability
If a locking mechanism with latch is added to maintain closed position, then the reliability of maintaining grip is improved, but the ease of operation deteriorates
Solution Approach 1:
The locking mechanism with latch is designed to automatically engage and disengage based on the natural movement of the camming device lever. When the lever moves to the closed position, the latch automatically locks into place to maintain the grip. When the lever is pulled to the open position, the latch automatically releases. This self-service mechanism reduces the need for manual locking and unlocking operations, maintaining ease of operation while ensuring reliable grip maintenance.
3Adaptability or versatility
If side portions are made movable to selectively grip the rail, then the adaptability to different rail positions is improved, but the device complexity increases
Solution Approach 1:
The movable side portions are merged with the base portion through a shared opening structure. The side portions slide within the opening of the base portion, combining the functions of support and movement into a single integrated structure. This merging reduces the need for separate mounting brackets and adjustment mechanisms, thereby reducing overall device complexity while maintaining adaptability to different rail positions.
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
The solution provides a secure and adjustable mounting system that effectively grips the rail, prevents loosening due to vibration, and allows for easy attachment and detachment of accessories, enhancing the stability and usability of weapon-mounted accessories.
Implementation Method 1
A camming device is interconnected with a second end of the elongated connecting member. The camming device engages the second side portion and is operable to pull the elongated connecting member such that the side portions are moved from a released position to an engaged position.
Implementation Method 2
The camming device includes a lever that moves the camming device between an open and a closed position.
Implementation Method 3
A locking mechanism is operable to lock the camming device in the closed position. The locking mechanism includes a locking element that is supported by the base portion or the side second portion and is movable between a lock position and an unlock position. The locking element has an engagement portion that selectively engages the camming device when the locking element is in the lock position thereby locking the camming device in the closed position.
Implementation Method 4
The mounting device may include a spring biasing the latch towards the lock position.
Implementation Method 5
the base portion has an opening defined therein and the movable side portion is slidingly received in the opening
Implementation Method 6
The elongated connecting member has a mid portion extending between the first and second ends and the first end of the connecting member is an adjusting nut threadingly engaged with the mid portion
Implementation Method 7
The second side portion has a curved cam receiving surface defined thereon, and the cam portion of the camming device is disposed against the curved cam receiving surface.

AI summary
A mounting device for mounting an accessory to a rail of a weapon includes a base portion and first and second side portions. One side portion is movable to grip the rail. An elongated connecting member has a first end engaging the first side portion and a second end connected to a camming device. The camming device engages the second side portion and pulls the elongated connecting member to move the side portions to an engaged position. A locking mechanism locks the camming device in the closed position. The locking mechanism includes a locking element that is movable between a lock position and an unlock position. The locking element has an engagement portion that selectively engages the camming device when the locking element is in the lock position thereby locking the camming device in the closed position.
