Furniture Suspension Hook Locking for Secure Wall Hanging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suspension devices for hanging furniture on walls face challenges in securing the furniture against unintentional detachment, particularly when the support element is pivoted relative to the counter bearing, and require additional material for a protruding lower fold, limiting their ability to be parked away from the wall.
Innovation Solution
A suspension device with a pivoted securing element that deflects into a blocking position when the hook part is hooked into the counter bearing, utilizing a blocking element to prevent unhooking, and optional spring bars for secure locking and easy release, allowing for secure attachment without additional material and enabling parking away from the wall.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If projections are arranged on the support element to prevent unintentional detachment, then security against detachment is improved, but device complexity and material requirements increase due to the need for a protruding lower fold on the counter bearing
Solution Approach 1:
Instead of having projections on the support element reach under a protruding lower fold of the counter bearing, the invention inverts the approach by having the securing element deflect through the counter bearing itself into a blocking position. This eliminates the need for the protruding lower fold on the counter bearing while maintaining security against unintentional detachment.
Solution Approach 2:
The securing element is designed to be deflectable rather than fixed, allowing it to move dynamically during the hooking process. When the hook part is hooked into the counter bearing, the securing element automatically deflects through the counter bearing into a blocking position that prevents unhooking, providing security without requiring complex pre-positioned projections.
2Reliability
If projections are positioned at a sufficient distance from the hook part to reach under the counter bearing, then security against detachment is improved, but assembly time increases due to the need to pivot the support element to a specific position
Solution Approach 1:
The securing element is pre-positioned on the support element in such a way that when the hook part is hooked into the counter bearing, it automatically deflects through the counter bearing into the blocking position. This preliminary positioning eliminates the need for manual adjustment or pivoting to specific positions during assembly, reducing assembly time while maintaining security.
Solution Approach 2:
The securing element performs its own positioning function automatically during the hooking process. As the hook part is inserted into the counter bearing, the securing element self-deflects into the blocking position without requiring external intervention or precise manual positioning, thereby reducing assembly time and improving reliability.
3Ease of operation
If the support element is pivoted away from the wall for parking, then accessibility is improved, but security against detachment is lost since projections no longer reach under the counter bearing
Solution Approach 1:
The securing element is designed to remain effective in both parked and suspended positions. When the support element is pivoted away from the wall for parking, the deflectable securing element maintains its blocking position, continuing to prevent unintentional detachment while allowing the furniture to be accessed.
Solution Approach 2:
The invention changes the parameter of the securing mechanism from fixed projections to a deflectable element that can adapt to different positions. This allows the securing element to maintain its blocking function whether the support element is in the suspended position against the wall or pivoted away for parking, providing both accessibility and security.
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 secure attachment and easy assembly of furniture, preventing unintentional detachment and allowing for parking away from the wall, while reducing material requirements and assembly time.
Implementation Method 1
a securing element (7) which is arranged in a deflectable manner on the support element (3) and is positioned in such a way that when the hook part (32) is hung on the counter-bearing (9), the securing element (7) deflects through the counter-bearing (9) into a blocking position that secures the support element (3) against unhooking
Implementation Method 2
at least one spring element (62) is arranged on the blocking element (6) with which the blocking element (6) can be locked in the locked position in a locking recess (311) of the support element (3)
