Wall Cabinet Suspension Fitting With Pivoting Anti-Detachment Stop
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suspension devices for furniture, particularly cupboard furniture, face challenges in preventing unintentional detachment from wall brackets, which can lead to personal injury and damage, and require complex adjustment mechanisms for detachment.
Innovation Solution
A suspension device with an adjustably mounted support bracket featuring a threaded bolt and guide slot allows the carrying strap to spread apart from the mounting element, enabling easy detachment without the need for active adjustment of anti-detachment means, utilizing a stop projection that engages under the wall bracket to prevent unintentional detachment and pivots relative to the wall bracket for intended release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an adjusting bolt is used to prevent unintentional detachment, then safety is improved, but device complexity increases
Solution Approach 1:
The invention extracts the adjustment function from a complex mechanical adjusting bolt system and replaces it with a simple pivoting motion of the support bracket. The stop projection automatically engages or disengages from the wall bracket depending on the pivot angle, eliminating the need for threaded bolts, nuts, and complex adjustment mechanisms while maintaining safety functionality.
Solution Approach 2:
The support bracket's pivoting motion automatically controls the engagement state of the stop projection with the wall bracket. When the bracket is in the secured position, the stop projection automatically engages to prevent detachment. When pivoted to the release position, the stop projection automatically disengages, allowing detachment. This self-service mechanism eliminates the need for external adjustment tools or complex control systems.
2Reliability
If an adjusting bolt is required for detachment, then security is improved, but ease of operation deteriorates
Solution Approach 1:
The system uses the natural pivoting motion of the support bracket during normal operation or removal to automatically control the engagement of the stop projection. No separate adjustment action is needed - the bracket's own movement serves to secure or release the attachment, making operation simple while maintaining security.
Solution Approach 2:
Instead of using an adjusting bolt to actively control engagement, the invention inverts the approach: the stop projection passively engages based on the bracket's position. The secured state is the default when the bracket is in its normal position, and release occurs naturally when the bracket is pivoted, reversing the conventional logic of active adjustment control.
3Reliability
If a stop projection is firmly arranged on the support bracket, then reliability is improved, but adaptability deteriorates
Solution Approach 1:
The stop projection is firmly attached to the support bracket, but the bracket itself is designed to pivot dynamically relative to the wall bracket. This dynamic pivoting motion allows the firmly arranged stop projection to automatically transition between engaged and disengaged states, maintaining both reliability when secured and adaptability when release is needed.
Solution Approach 2:
The solution adds a rotational dimension to the system. The stop projection remains firmly positioned on the support bracket in one dimension, but the support bracket pivots in another dimension (rotation), allowing the stop projection to engage or disengage from the wall bracket based on the pivot angle, thus maintaining both firm attachment and operational flexibility.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a reliable, inexpensive, and easy-to-handle suspension system that securely attaches furniture to the wall while allowing simple detachment without complex adjustments, ensuring safety and preventing unintentional disengagement.
Implementation Method 1
the adjustment means having a threaded bolt which has a bolt head and which is inserted in an opening designed as a threaded bore in the mounting element, with the threaded bolt reaching through the support bracket in the area of the base body and with its bolt head resting on the upper side of the base body
Implementation Method 2
an adjustment of the threaded bolt causes the base body and thus the carrying strap to be carried along, whereby the carrying strap can be spread out from the mounting element

AI summary
The device (11) has mounting element (12) on which support tab (17) is arranged. A wall holder (24) is mounted on mounting element, and securing unit is provided on base portion (18) of support tab. A stop lug (29) is aligned in support tab such that detachment of wall holder is prevented. The support tab is movable into release position, in which stop lug passes out of wall holder. The stop lug is secured to supporting tab and support plate of wall holder with respect to pivoting movement in which supporting tab is pivotable from use position into release position.
