Foldable Lockable Ladder Rung Guard
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ladder guard devices are not easily transportable, adjustable to fit different ladder lengths and rung spacings, nor are they secure for intended users while being difficult for unauthorized users to remove.
Innovation Solution
A foldable, adjustable, and lockable cover for ladder rungs, featuring panels with lips and hinges, an adjustable member with locking holes, and a locking mechanism, making it difficult for unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed rigid ladder guard is used, then security against unauthorized access is improved, but transportability and adaptability to different ladder configurations deteriorate
Solution Approach 1:
The ladder guard is divided into multiple panels that can be folded and configured to match different ladder structures. This segmentation allows the guard to adapt to various ladder lengths and rung spacings while maintaining security when assembled and locked in place.
Solution Approach 2:
The ladder guard transitions from a static fixed structure to a dynamic foldable design that can be adjusted and reconfigured. The foldable panels and adjustable members enable the guard to adapt to different ladder configurations while remaining secure when locked during use.
2Reliability
If a custom-fitted rigid guard is used, then security is improved, but ease of transport and storage deteriorates
Solution Approach 1:
The foldable panels of the ladder guard can be collapsed into a compact configuration that nests together, significantly reducing the space required for transport and storage while maintaining the same security performance when deployed and locked.
3Ease of operation
If a simple removable cover is used, then ease of installation is improved, but difficulty of removal by unauthorized users deteriorates insufficiently
Solution Approach 1:
A lock mechanism serves as an intermediary between the user and the ladder guard. The lock requires a key or combination, providing controlled access: authorized users can easily install and remove the guard with the key, while unauthorized users face significant difficulty removing it without the key.

AI summary
The invention, according to an embodiment, is a foldable, adjustable, and lockable cover for a plurality of rungs of a ladder. The device renders a ladder prohibitively difficult to climb. In an embodiment, the device is attached to a ladder using a lock, such as a bike lock or padlock, at a top portion of the device, rendering it difficult to for an unauthorized user to climb the ladder to cut any lock holding the device in place and/or remove the ladder.
