Wall Cupboard Hanging Bracket With Screw-Lock Anti-Disengagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing visible hanging brackets for wall cupboards are prone to accidental disengagement due to upward and lateral forces, posing safety risks, especially when installed at low heights, and current anti-disengagement systems can be complicated to assemble and may not function effectively due to interference with wall fixtures.
Innovation Solution
A visible hanging bracket with a perfected anti-disengagement system featuring a screw with a threaded section and a shaped head that engages with a horizontal flap on the support bar, forming side stops to prevent disengagement from both upward and lateral forces, without requiring additional material or operations, and allowing easy disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a visible hanging bracket uses a simple hook design for wall cupboards, then the device complexity is reduced and ease of manufacture is improved, but the reliability against accidental disengagement deteriorates
Solution Approach 1:
The patent combines the anti-disengagement mechanism with the existing hook structure by integrating a bead that screws onto the hook and interacts with the support bar. This merging approach adds safety functionality without requiring a completely separate system, thus improving reliability while controlling device complexity
Solution Approach 2:
The anti-disengagement system uses a dynamic bead that can be screwed onto or off the hook, providing adjustable protection. The bead moves horizontally along the hook and engages with the support bar only when needed, creating a dynamic safety mechanism that adapts to different installation scenarios while maintaining simplicity
2Reliability
If a bead is screwed onto the hook for anti-disengagement, then the reliability against upward forces is improved, but the ease of operation deteriorates due to potential interference with wall fixtures
Solution Approach 1:
The patent extracts the potential interference issue by designing the bead to engage with a specific horizontal flap or groove on the support bar rather than the entire bar. This extraction of the engagement point ensures the bead interacts only with the necessary portion of the support structure, avoiding interference with wall fixtures while maintaining ease of operation
Solution Approach 2:
The horizontal flap or groove on the support bar acts as an intermediary element between the bead and the wall fixture. This intermediary structure allows the bead to engage securely for anti-disengagement protection while preventing direct contact with wall fixtures that could cause interference, thus maintaining ease of operation
3Adaptability or versatility
If the hanging bracket is installed at low heights to meet modern assembly customs, then the adaptability to current usage patterns is improved, but the reliability against accidental disengagement deteriorates due to increased risk from children
Solution Approach 1:
The patent applies preliminary anti-action by pre-installing the bead on the hook before mounting the cupboard. This preliminary action ensures the anti-disengagement mechanism is already in place and configured correctly before the cupboard is installed at any height, preventing accidental disengagement from the outset while allowing adaptability to low-height installations

AI summary
A visible hanging bracket with an anti-disengagement system for wall cupboards, wherein a cupboard (29) is hooked to a support (17) fixed to the wall (18) by means of a hook (11) with a tooth (15) of a hanging- bracket device (10) of the type in which releasable reciprocal constraint means (21) are envisaged between said hook (11) and said support (17), consisting of a screw (21) screwed onto said hook (11) and suitable for interfering with said support (17). According to the invention, said screw (21) is screwed into a threaded seat (26) positioned on a section (27) forming part of and incorporated in said hook (11), said section (27) being opposed, to said tooth (15), at a height (q) substantially identical, and that the tip or end part (23) of said screw (21) is engaged with a horizontal flap (edge) (16A) folded directly from the section (16) of the bar (17).
