Pivoting Dual Hook Clasp With Retentive Latching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Standard hooks, such as S and C hooks, often have throats that are either too deep or too shallow for specific applications, leading to tangling issues with cords and hooks, inadequate user grip, and a tendency to detach from objects due to slack or vibrations.
Innovation Solution
A versatile hook assembly with two parallel hooks that pivot independently about a common joint, allowing various configurations and featuring complementary retaining elements to enhance retention and prevent detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If standard S and C hooks are used, then they are simple in design, but they tend to detach from objects due to cord slack, shifting cargo, or vibrations
Solution Approach 1:
The invention combines two hooks with a common pivot joint and complementary retaining elements to create a unified mechanism that prevents detachment. The retaining elements on each hook engage with the other, creating a locked configuration that resists forces from cord slack, cargo shifting, and vibrations, thereby improving reliability while maintaining relatively simple design.
2Reliability
If hooks are designed for specific applications with specialized shapes, then they provide adequate grip and prevent tangling, but they reduce versatility and require multiple hook types
Solution Approach 1:
The dual hook design serves multiple functions: each hook can be used independently for simple applications, or together they provide secure engagement with retaining elements for more demanding applications. The pivoting mechanism allows the hooks to adapt to different configurations, providing both tangle prevention and secure grip across various applications without requiring multiple specialized hook types.
3Device complexity
If a single hook is used, then the design is simple, but it provides inadequate user grip and may cause injury when recoiling
Solution Approach 1:
The single hook is divided into two separate hooks that can be gripped independently. The user can hold one hook while the other engages with the object, providing better control and safety. The pivoting joint allows the hooks to move independently, enabling the user to maintain a secure grip without the risk of sudden recoiling that occurs with a single rigid hook.

AI summary
A clasp having two opposing parallel hooks coupled together by a pivot joint. The shank of the first hook is disposed above the plane of rotation while the bend of the first hook is disposed below the plane, and the shank of the second hook is disposed below the plane while the bend of the second hook is disposed above the plane. A protrusion on the first shank engages with a depression on the second shank to latch the clasp in a “closed” configuration. The protrusion engages with an edge of the second shank to latch the clasp in a “crossed” configuration.
