Kitchen Drawer Mounting Frame on U-Shaped Rail Covers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Standard drawers cannot be used in constructions that require a baseless receiving frame without railings, as they need top shoulders for the receiving frame to be securely mounted.
Innovation Solution
The receiving frame is mounted loosely on U-shaped covers of the drawer frames, which act as a stable base, with side straps projecting downwards to prevent lateral slipping, and can be used in both baseless and standard drawers, allowing for increased container height and space optimization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a standard drawer is used, then the drawer structure is simple and easy to manufacture, but the receiving frame cannot be securely mounted without top shoulders
Solution Approach 1:
Instead of mounting the receiving frame on top shoulders from below, the invention inverts the mounting approach by providing U-shaped covers that extend upward from the drawer frame, allowing the receiving frame to be mounted from above onto these covers. This inversion eliminates the need for top shoulders while maintaining secure mounting.
Solution Approach 2:
The U-shaped covers act as an intermediary element between the drawer frame and the receiving frame. These covers extend upward from the drawer frame and provide a mounting surface for the receiving frame, thereby mediating the connection between the drawer structure and the container support without requiring top shoulders.
2Reliability
If railings are added above the drawer frames to support the receiving frame, then mounting security is improved, but the space below the drawer frames is reduced
Solution Approach 1:
The invention changes the vertical dimension of the support structure by extending U-shaped covers upward from the drawer frame rather than placing horizontal railings above it. This vertical extension provides mounting security while minimizing the horizontal space occupation, thereby preserving the usable volume below the drawer frames.
3Volume of moving object
If the receiving frame is mounted on U-shaped covers, then space utilization is improved and container height can be increased, but the covers must have sufficient load capacity
Solution Approach 1:
The U-shaped covers are constructed as composite structures combining a profiled base element with an additional stiffening element. This composite construction provides the necessary load capacity to support the receiving frame and containers while maintaining a compact design that maximizes usable space.

AI summary
The invention relates to a drawer, preferably without a bottom and particularly for a kitchen cabinet, with a drawer frame (2) on each longitudinal side, a front cross member (3), optionally formed by a front wall, a rear cross member (4), optionallyformed by a back panel, the components of which are connected to each other in such a way as to form an internally open frame construction, and further comprising a support-free mounting frame (5) with longitudinal sides associated with the drawer sides (2) and transverse sides associated with the cross members (3, 4), which spans the internal space left by the frame construction, wherein each drawer side (2) has a moving rail (6) of a telescopic extension and an upwardly curved cover (8) of the moving rail (6) that is approximately inverted U-shaped in cross-section, and wherein the mounting frame (5) has at least one recess (9) for preferably suspending a container (10), in particular a waste collection container (10). This is characterized in that the mounting frame (5) is supported on or against the covers (8) of the drawer sides (2).
