Scissor-Type Securing Assembly for Fast Load Anchoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anchor systems for securing loads and safety elements in construction are laborious to install, require additional components, and can be aesthetically unsuitable for permanent installations, with complex handling procedures and potential for high costs and aesthetic modifications.
Innovation Solution
A scissor-type securing element with pivotably connected hooks and a shackle integrated into the design, featuring an insertion configuration that prevents rotation during placement and a securing configuration allowing rotation for load orientation, along with a frangible load indicator and a positioning disk for precise and cost-effective installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional anchors with rings and plates are used, then secure load holding is achieved, but installation becomes long and laborious requiring additional screws and plugs
Solution Approach 1:
The patent combines the anchor body, mounting plate, and fastening mechanism into a single integrated scissor-type element. The two hooks pivotably connected by a rotary shaft form a unified structure that performs both anchoring and fastening functions simultaneously, eliminating the need for separate screws and plugs.
Solution Approach 2:
The anchor is divided into two movable hooks that can pivot relative to each other, allowing the structure to transition between insertion and securing configurations. This segmentation enables the anchor to be inserted in a compact form and then deployed to its full functional shape.
2Reliability
If traditional anchors with multiple components are used, then secure fastening is achieved, but device complexity increases with additional fastening plugs and screws
Solution Approach 1:
The patent merges multiple fastening functions into a single scissor-type mechanism. The two hooks with penetrating slots and teeth work together as one integrated fastening system, replacing the need for separate screws, plugs, and other fastening components.
3Reliability
If anchors are designed for permanent installation, then load security is maintained, but aesthetic modification of construction increases with multiple anchoring points
Solution Approach 1:
The scissor-type anchor features a nested configuration where the two hooks can be superposed in the insertion configuration, creating a compact form that minimizes the visual profile when not in use. This nesting allows the anchor to remain fixed permanently while maintaining aesthetic appeal.
4Ease of operation
If scissor-type securing element with integrated shackle is used, then handling is facilitated and rotation is prevented during insertion, but device complexity increases with additional shaft ends and housings
Solution Approach 1:
The shaft ends are pre-positioned to project laterally from the hooks, and the housings are pre-formed on the ring ends with complementary shapes. This preliminary configuration ensures that when the anchor is inserted, the shaft ends automatically engage with the housings to prevent rotation, without requiring additional adjustment steps.

AI summary
The invention relates to a scissor-type securing element (1) comprising two hooks (2, 3) pivotably connected together by a rotary shaft (4), a distal part being defined in each hook (2, 3) on one side of the shaft (4) and a proximal part being defined on the other side of the shaft (4), each distal part being provided with a tooth (21, 31) and each proximal part being provided with a penetrating slot (22, 32). According to the invention, the securing element has an insertion configuration (P1) in which the hooks (2, 3) are superposed, and a securing configuration (P2) in which the teeth (21, 31) are in a more separated position and the hooks (2, 3) project so as to remain retained in an inner support surface (51) of a case (5). The securing element (1) comprises a shackle (6) provided with: a ring (61) for supporting the load, two ring ends (62, 63) and a key (64) supported by the two ends (62, 63) and inserted into the slots (22, 32), the ends (41, 42) of the shaft (4) projecting laterally and the ring ends (62, 63) being provided with a housing (65) having a form complementary to the ends (41, 42) of the shaft (4), such that in the insertion configuration, each end (41, 42) of the shaft (4) is inserted into a housing (65).
