Rapid-Release Latching Arrangement for Rotatable Bolt Wear Balance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locking mechanisms in lifting, lashing, and attachment technologies require time-consuming assembly and may lead to one-sided wear of bolts, and often necessitate additional safety elements like dowel pins.
Innovation Solution
A latching arrangement featuring a spring-loaded latching projection on one component that fits into a receptacle with a latching recess, secured by a movable release shoulder accessible via a manual switch, allowing for quick attachment and detachment without additional safety elements and ensuring even wear of the bolt.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a bolt is secured by a clamping sleeve in a circumferential groove, then the bolt can be rotated and avoid one-sided wear, but the assembly becomes time-consuming and requires additional safety elements
Solution Approach 1:
The invention extracts the clamping sleeve and additional safety elements from the system, replacing them with a self-retaining bolt design where the bolt head directly engages with the eyelet through a receptacle geometry that prevents removal without requiring separate retaining components
Solution Approach 2:
The invention merges the functions of the bolt head, retaining mechanism, and wear prevention into a single integrated design where the hexagonal bolt head geometry simultaneously provides rotational capability, structural strength, and self-retention within the receptacle, eliminating the need for separate clamping sleeves
2Reliability
If a bolt is secured by a clamping sleeve, then the bolt remains secured even if rotation is restricted, but the clamping sleeve can wear out and become unsecured
Solution Approach 1:
The bolt design serves itself by using its own hexagonal head geometry to engage with the receptacle walls, creating a self-retaining mechanism that does not depend on separate wearing components like clamping sleeves, thereby eliminating the wear-out failure mode of the securing element
Solution Approach 2:
The receptacle geometry is designed with specific engagement surfaces and dimensions that anticipate and prevent bolt removal before wear can occur, creating a fail-safe design where the bolt remains secured throughout its entire service life without relying on the durability of separate retaining components
3Ease of operation
If threads are used to allow the bolt to be screwed through, then the bolt can be rotated and remains secured by the thread, but the threading process adds complexity and time
Solution Approach 1:
The invention extracts the threading mechanism entirely from the system, replacing it with a direct insertion design where the hexagonal bolt head is simply placed into the receptacle and retained by geometry alone, eliminating threads, screwing operations, and associated complexity while maintaining rotational freedom
4Reliability
If additional safety elements like dowel pins are used, then the securing reliability is improved, but the device complexity and assembly time increase
Solution Approach 1:
The invention merges the securing function into the basic bolt-receptacle connection geometry, where the hexagonal head engagement with the receptacle walls provides inherent retention without requiring separate dowel pins or safety elements, thereby reducing component count while maintaining reliability
Solution Approach 2:
The hexagonal bolt head serves multiple functions simultaneously: it provides structural strength, enables rotational freedom, and creates self-retention through engagement with the receptacle geometry, eliminating the need for specialized additional safety components

AI summary
The invention relates to a latching arrangement (1), in particular for a component (6) from lifting, lashing or fastening technology. The latching arrangement comprises a first component (2) which is provided at its one end (32) with at least one laterally protruding, spring-tensioned latching projection (20). Furthermore, the latching arrangement (1) comprises a second component (4) which is provided with a receptacle (50) in which the end (32) of the first component (2) can be received in an insertion direction (18) and can be fastened rotatably. The receptacle (50) has a latching recess (52) for the latching projection (20). The latching recess is bounded on at least one side by a release shoulder (58) which is displaceable into the latching recess (52). The release shoulder is connected in a movement-transmitting manner or rigidly in terms of movement, in particular monolithically, to a movable hand switch (80) which is arranged so as to be accessible from outside the latching arrangement (1). The hand switch (80) closes the receptacle. In this embodiment, the first component is latched rotatably in the second component. By simple actuation of the hand switch (80), the latching can be repeatedly and easily released.
