Rigid Pivoting Pull-Out Locking Element for Furniture Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pull-out locking devices for furniture often have complex multi-part structures that are not inherently rigid, which can limit the stroke between locking and release positions and complicate the design, making them less effective in preventing furniture imbalance.
Innovation Solution
The use of rigid, single-body support elements with all support surfaces integrated as one piece, allowing for a larger stroke and simplified design, where these elements pivot about a pivot axis between locking and release positions on the guide element, and trigger elements facilitate the transition between these states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If multi-part support elements are used, then the structure can be assembled from separate components, but the stroke between locking and release positions is limited and the design becomes complex
Solution Approach 1:
The patent merges multiple separate support surfaces (upper support surface, lower support surface, and further support surface) into a single rigid support element. This integration eliminates the need for multiple separate components and their associated assembly mechanisms, thereby enabling a larger stroke between locking and release positions while reducing structural complexity.
2Reliability
If support elements are constructed in several parts, then manufacturing and assembly may be simplified, but the inherent rigidity is reduced and effectiveness in preventing furniture imbalance is compromised
Solution Approach 1:
The invention combines multiple support surfaces into one rigid, monolithic support element. This merging provides inherent rigidity that effectively prevents furniture imbalance, while the integrated design actually simplifies the overall structure by eliminating the need for multiple separate parts and their connection mechanisms.
3Ease of operation
If multiple separate components are used in support elements, then assembly flexibility is improved, but the stroke length and structural simplicity are reduced
Solution Approach 1:
The patent integrates all support surfaces into a single support element that pivots as one unit. This merging enables a larger stroke between locking and release positions, while the pivotable mounting on the guide rail maintains assembly flexibility, allowing the support element to be easily installed and operated.

Function Achieved in This Case
This design enhances the stability of furniture by allowing a larger stroke between locking and release positions, preventing furniture imbalance effectively while simplifying the structure and reducing the complexity of the locking mechanism.

AI summary
The device (1) has a support element (5) e.g. locking hook, exhibiting a locking position for engagement with a support surface at another support element. The support element is formed as a body rigidly connecting an upper support surface, a lower support surface and another support surface with one another. Each support element is pivotably mounted at a pivot axis at a guide element (3) e.g. groove-like channel, between the locking position and a release position. The support surfaces are arranged outside the guide element. The body is an injection molded plastic body or an integral metal or ceramic body.
