Guiding means for guiding a furniture part
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing furniture guiding systems face challenges in maintaining functional and operational safety, particularly in the triggering situation of furniture parts in closed positions, where adjustments can lead to failure of transmission means, preventing synchronous operation of guides and locking mechanisms.
Innovation Solution
The system incorporates adjustable transmission means with ejection and retraction arrangements, ensuring synchronous displacement of movement rails and maintaining functional integrity by adjusting counter-elements to match contact elements on the movement rail, allowing for reliable operation across various adjustment settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If adjustment means are provided to specify the closed position of the furniture part, then the closed position can be adjusted relative to the furniture body, but the transmission means may fail to function properly when the position is changed
Solution Approach 1:
The patent applies preliminary action by pre-configuring the transmission means to automatically adjust when the closed position is changed. The counter-element is positioned and dimensioned such that it automatically compensates for position changes, ensuring the transmission means remain functional without requiring manual reconfiguration after each adjustment.
Solution Approach 2:
The patent utilizes parameter changes by designing the counter-element with specific dimensional parameters that allow it to accommodate variations in the closed position. The counter-element's position and dimensions are calculated to maintain proper engagement with the contact element across the full range of adjustable positions, thereby preserving transmission functionality.
2Reliability
If both guides must be released simultaneously to unlock the furniture part, then the closed position is securely maintained, but the operation complexity increases due to required synchronous release
Solution Approach 1:
The patent merges the release operations of both guides by providing a single contact element on the furniture part that simultaneously engages with counter-elements on both movement rails. A single triggering action on the furniture part causes both guides to be released at the same time, eliminating the need for separate release operations while maintaining secure closed position.
Solution Approach 2:
The contact element serves as an intermediary that transmits the triggering force from the furniture part to both guides simultaneously. This intermediary mechanism ensures that both guides are released in a coordinated manner through a single user action, simplifying operation while maintaining the reliability of the dual-guide system.

AI summary
The device (1) has an adjusting unit for presetting a closing position of a movable furniture part relative to a furniture body. The adjusting unit adjusts the furniture part by maintaining the closing position along a moving direction, which is provided by guide units (2). The adjusting unit is designed so that adjusting of a position of a transfer unit is carried out couplingly with adjusting of the closing position of the movable furniture part so that a function of the transfer unit remains unchanged with the adjustment of the position of the transfer unit. An independent claim is also included for a guide unit.
