Drawer Container Rail Stops for Tilt-Free Guide Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drawer arrangements often result in lateral displacement and tilting of drawer containers during assembly, leading to potential damage to the drawer side walls and furniture body surfaces due to the lack of precise guidance and pre-positioning mechanisms.
Innovation Solution
Incorporating at least one stop in the U-shaped section of the container rail, which runs in the longitudinal direction, to stabilize the drawer container's mounting on the drawer extension guides, preventing tilting and ensuring accurate alignment and attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the drawer container is manually guided during assembly without pre-positioning mechanisms, then the assembly process is simple, but lateral displacement and tilting occur leading to damage to drawer side walls
Solution Approach 1:
The patent applies preliminary action by incorporating stops in the U-shaped section of the container rail that pre-position the drawer container on the drawer rails before final attachment. This preliminary positioning mechanism guides the drawer container into correct alignment, preventing lateral displacement and tilting during assembly, thereby resolving the contradiction between assembly simplicity and alignment precision
2Productivity
If the drawer container is inserted quickly without guidance mechanisms, then assembly speed is high, but tilting and scratching of sensitive surfaces occur
Solution Approach 1:
The patent uses stops as intermediary elements within the U-shaped section of the container rail. These stops act as mediators that guide and control the insertion of the drawer container onto the drawer rails, ensuring proper alignment and preventing direct contact between the drawer side walls and the furniture body surfaces, thus enabling fast assembly without surface damage
3Device complexity
If no pre-positioning mechanism is used, then the device structure is simple, but stable mounting cannot be achieved
Solution Approach 1:
The patent applies segmentation by dividing the container rail into a U-shaped section with integrated stops and the remaining rail structure. The stops are positioned at specific locations within the U-shaped section to provide discrete pre-positioning points for the drawer container, creating a segmented structure that ensures stable mounting without excessive complexity

AI summary
The invention relates to a drawer arrangement, comprising a container rail (1) preinstalled on a drawer container (2) and a drawer pull-out guide (5) having a movable drawer rail (4), wherein the drawer container (2) can be rigidly connected to the movable drawer rail (4) of the drawer pull-out guide (5) by means of the container rail (1) so that the drawer container is supported in such a way that the drawer container can be moved out relative to a furniture body (3), wherein the container rail (1) has a section (6) having a substantially U-shaped cross-section, which section accommodates the drawer rail (4) in the assembled state, wherein at least one stop (7, 7a) for the drawer rail (4) extending in the rail longitudinal direction (L) is formed in the U-shaped section (6).
