Container Handle Locking Cage for Anti-Tip Wall Securing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wheeled waste containers are prone to being knocked over by animals or strong winds, especially when left outdoors, leading to nuisance and potential spillage.
Innovation Solution
An anti-rollover device that immobilizes a laterally projecting handle of the container to a vertical support using a cage with a longitudinal housing and a closing mechanism, allowing the handle to be secured without lifting the container.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a U-shaped hook retaining device is used to immobilize the container handle, then the container can be secured to a vertical support, but the container must be lifted to insert the handle into the hook, which is cumbersome and inconvenient
Solution Approach 1:
Instead of requiring the handle to be inserted upward into a hook (as in prior art), the invention inverts the approach by providing a longitudinal housing that receives the handle horizontally as the container is rolled into position. The closing means then secures the handle from above, reversing the insertion direction and eliminating the need to lift the container.
Solution Approach 2:
The invention introduces a closing means as an intermediary element that actively secures the handle within the longitudinal housing. This closing means acts as a mediator between the handle and the vertical support, providing reliable immobilization through a automated closing action rather than requiring manual insertion into a passive hook structure.
2Reliability
If the container is lifted to insert the handle into the retaining device, then the handle can be secured in the retaining device, but this requires additional physical effort and time
Solution Approach 1:
The longitudinal housing is pre-positioned on the vertical support at the appropriate height and orientation. As the container is rolled into place, the handle automatically aligns with and enters the pre-prepared housing, eliminating the need for lifting and manual insertion operations that consume time and effort.
Solution Approach 2:
The system is designed so that the container's own movement (rolling into position) performs the insertion action. The handle automatically enters the longitudinal housing through the container's rolling motion, making the securing process self-service rather than requiring external manual intervention to lift and insert the handle.
3Ease of operation
If a lateral opening is provided in the cage for handle insertion, then the handle can be inserted by rolling the container, but the opening must be closed to ensure proper immobilization
Solution Approach 1:
The closing means transforms the static cage structure into a dynamic system. The lateral opening is not merely a fixed hole but is controlled by a closing means that can open to allow handle insertion and then close to secure the handle. This dynamic element adds functionality without significantly increasing overall structural complexity.
Solution Approach 2:
The closing means serves multiple functions: it closes the lateral opening to secure the handle, provides a locking mechanism to prevent handle removal, and can be designed to allow easy opening for container removal when needed. This multi-functional element justifies the added complexity by delivering multiple operational benefits from a single structural addition.

AI summary
Anti-rollover device (1) for a wheeled container (CR) configured to immobilize a handle (PG) of the container, projecting laterally, to a vertical support (SV) such as a wall (M) or furniture extending vertically from a floor, said anti-rollover device comprising: - at least a first cage (Ca1) and preferably a second cage (Ca2) spaced apart from each other by a free clearance (DG) each comprising an upper wall (10), a lower wall (11), a bottom wall (12) defining a groove forming a longitudinal housing (LG) for a horizontal bar of the handle, the groove having a lateral opening (OL) to allow insertion of the horizontal bar of the handle into the groove, - a first closing means (131) and preferably a second closing means (132) synchronized by a mechanical link (LI),The locking mechanisms are configured to transition from an open state (EO) to a closed state (EF) of the lateral opening, ensuring that the handle is immobilized.
