Solution Overview

Problem

Existing sling mount systems for firearms fail to effectively accommodate both left- and right-handed users, often requiring modification of the gun sight and lacking silent and quick detachment capabilities.

Innovation Solution

A sling mount system that attaches to the weapon's buffer tube with a two-part clamp and swivel connector, allowing for silent coupling and uncoupling without moving parts, and featuring a single attachment point for quick and easy operation, including a receptacle that angles away from the buffer tube for smooth weapon transition.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the sling mount attaches to the gun sight, then the sling can be securely mounted, but the gun sight is damaged or modified

Engineering Contradiction:
Improvesling mounting securityVSAvoidgun sight damage
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The invention extracts the mounting function from the gun sight and relocates it to the buffer tube. The buffer tube mounting device includes a clamp member that attaches to the buffer tube, separating the sling mounting function from the gun sight assembly, thereby avoiding damage to the gun sight while maintaining secure sling attachment.

Inventive Principle:
Principle #2Taking out (Extraction)

2Ease of operation

If the sling mount uses moving parts for attachment, then the sling can be easily attached and detached, but noise is generated during coupling and uncoupling

Engineering Contradiction:
Improvesling attachment easeVSAvoidnoise during coupling
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The invention replaces traditional mechanical coupling mechanisms with a friction-fit system. The receptacle in the buffer tube mounting device receives the connector through a friction-fit arrangement, eliminating moving parts and mechanical coupling actions that generate noise, while maintaining ease of attachment and detachment through simple insertion and removal motions.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Device complexity

If the sling mount has a fixed orientation, then the structure is simple, but it cannot accommodate both left- and right-handed users

Engineering Contradiction:
Improvemount structure simplicityVSAvoidhandedness accommodation
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The invention introduces dynamic adjustability to the mounting system through a receptacle that can rotate within the clamp member. This allows the connector to be oriented in different positions, enabling the same simple clamp structure to accommodate both left-handed and right-handed users by adjusting the connector's angular position within the receptacle.

Inventive Principle:
Principle #15Dynamics

4Productivity

If the sling mount allows quick detachment, then the weapon can be quickly indexed, but the detachment mechanism becomes complex

Engineering Contradiction:
Improveweapon indexing speedVSAvoiddetachment mechanism complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The invention employs a self-release friction-fit mechanism where the connector is held in place by friction within the receptacle but can be easily released by simple insertion or removal motions. This self-service mechanism eliminates the need for complex locking or latching systems, achieving quick detachment through intuitive user actions without requiring complex mechanical sequences.

Inventive Principle:
Principle #25Self-service

AI summary

A sling mount system having a mount with associated receiver for releasable connection with a swivel connector having a longitudinal axis that lies in the same plane as a longitudinal axis of a weapon and that angles downward away from the butt stock. The receptacle for the swivel connector is integrally formed in the mount to facilitate silent connection and disconnection of the swivel mount thereto.
