Padlock Extender for Accessible Closure Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Padlocks often pose accessibility issues due to inconvenient installation locations and inefficient use, particularly when multiple locks are required to secure two mechanisms simultaneously.
Innovation Solution
An apparatus featuring an extender with a hook and annulus, secured to both a closure and a fixed structure, limits movement between the two and allows for convenient padlock placement, with a detachable shackle and sliding rigid sheath for enhanced security and accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a padlock is installed at a standard location on a closure, then the locking mechanism is secure, but the padlock becomes difficult to access and operate due to inconvenient elevation or lighting conditions
Solution Approach 1:
The extender adds a spatial dimension to the locking system by extending the shackle away from the closure surface, creating a new operational plane that is more accessible while maintaining the security function at the original location
2Reliability
If multiple padlocks are used to secure two locking mechanisms, then both mechanisms are secured, but the device complexity and number of components increase
Solution Approach 1:
The extender merges the function of multiple locking mechanisms into a single padlock system by providing a common shackle that can engage with multiple annular fasteners, thereby securing multiple points with one lock
3Ease of operation
If the extender allows easy detachment by removing the shackle, then accessibility and ease of operation improve, but security may be compromised if the detachment mechanism is too easy to activate
Solution Approach 1:
The locking system is segmented into separable components (shackle, annular fasteners, closure) that can be independently manipulated, allowing legitimate users to detach easily while requiring deliberate action for unauthorized removal

AI summary
An apparatus for securing a closure such as door or a window that opens and closes by movement relative to a fixed structure such as a wall or a floor. Many embodiments provide a device for relocating a padlock from its normal location where it secures a fastener (such as a hasp) to a location for the padlock that is more accessible for locking and unlocking the padlock. Typically an extender is provided, where the extender has a hook at a first end that is disposed through the eye of the staple of the hasp, and at an opposing second end the extender has an annulus, such as a hole in the extender or a loop or ring affixed to the extender. The shackle of the padlock may be disposed through the annulus and may be disposed through the eye of a second staple to secure the door or window in a closed or open position. Some embodiments employ a rigid sheath to enclose at least a portion of the extender. Typically the rigid sheath has an open state where the hook is exposed outside the sheath and a closed state where the hook is disposed within the sheath.
