Furniture Pull-Out Guide with Catch Device for Adjustment Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing guide devices for furniture pull-outs face challenges in maintaining functional effectiveness during adjustments in position, such as side or tilt adjustments, as components on the moveable furniture can jump off the track, disrupting the operation of combined functional devices like damping or self-retracting mechanisms.
Innovation Solution
A catch device with a bearing mechanism and control surface ensures that the functional elements remain effective during position adjustments by allowing the moveable first functional element to be suspended relative to the furniture pull-out and the stationary second functional element to be fixed to the furniture body, ensuring proper alignment and contact for functional operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If functional devices are combined with guide devices for furniture pull-outs, then the functionality is improved, but the reliability deteriorates during position adjustments as components jump off track
Solution Approach 1:
A control element with a control surface is introduced as an intermediary between the first and second functional elements. This control surface guides the moveable first functional element, ensuring it remains properly aligned with the stationary second functional element even during position adjustments of the furniture pull-out, preventing components from jumping off track
Solution Approach 2:
The first functional element is designed to be moveable relative to the furniture pull-out through a bearing mechanism, while the second functional element remains stationary relative to the furniture body. This dynamic configuration allows the system to adapt to position adjustments while maintaining functional contact through the guiding control surface
2Adaptability or versatility
If the position of moveable furniture is adjusted relative to guide device, then the adaptability is improved, but the functional effectiveness deteriorates as components jump off track
Solution Approach 1:
The control surface acts as a mediator that maintains the functional relationship between moving and stationary components during position adjustments. It ensures the first functional element stays guided on the second functional element regardless of changes in the furniture pull-out's position relative to the guide device
Solution Approach 2:
The functional device is divided into two separate functional elements: a moveable first functional element attached to the furniture pull-out and a stationary second functional element attached to the furniture body. This segmentation allows independent movement and adjustment while maintaining functional contact through the control surface guidance

AI summary
A guide device for guiding a furniture pull-out moveable relative to a furniture body comprises: at least one guide unit having a body rail that can be fastened to the furniture body and at least one running rail that is displaceably mounted relative to the body rail; and a functional device comprising at least a first functional element that can be fastened to the moveable furniture pull-out, at least one body-sided second functional element, both functional elements being guided on one another during the retraction movement and/or the extension movement of the furniture pull-out, and a catch device having a bearing mechanism by which the first or second functional element can be moveably hung and having a control surface formed on the first and/or second functional element by which the moveable first functional element can be captured to subsequently guide on the second functional element.
