Drawer Frame Tilt Adjustment With Interior-Access Actuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drawer frame members with inclination adjustment mechanisms face difficulties in accessing the adjusting screw, especially when drawers are closely superposed, making it hard to adjust the height of the drawer frame member comfortably and efficiently.
Innovation Solution
The introduction of an actuating element accessible from the drawer interior, which can be rotated or moved linearly, allows for easy adjustment of the drawer frame member's height, featuring a support foot that rests on the drawer extension guide and converts rotary motion into translational movement, with a spiral worm for self-locking adjustment, facilitating access even when drawers are partially open or closely spaced.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the adjusting screw is positioned above the drawer frame member for height adjustment, then the adjustment function is achieved, but the accessibility to the adjusting screw becomes difficult when drawers are closely superposed
Solution Approach 1:
The adjusting mechanism is moved from a vertical position above the drawer frame member to a horizontal position at the rear end of the drawer frame member. This spatial repositioning allows the adjusting screw to be accessed from the side/rear direction rather than from above, significantly improving accessibility when drawers are closely superposed while maintaining the height adjustment function.
2Shape
If the drawer frame member is adjusted for inclination to achieve aesthetic appearance, then the visual alignment of drawer fronts is improved, but the complexity of the adjustment mechanism increases
Solution Approach 1:
The height adjustment function and inclination adjustment function are merged into a single adjusting mechanism located at the rear end of the drawer frame member. By combining these functions, the patent achieves both aesthetic inclination adjustment and functional height adjustment without significantly increasing device complexity, as both adjustments are accomplished through the same mechanical structure.
Solution Approach 2:
The adjusting mechanism at the rear end of the drawer frame member serves multiple functions: it provides both height adjustment and inclination adjustment capabilities. This multi-functional design allows a single mechanism to address both the aesthetic requirements (inclination for visual alignment) and the functional requirements (height for proper drawer operation) without requiring separate adjustment systems.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution enables comfortable and efficient height adjustment of the drawer frame member, improving accessibility and stability, allowing for better aesthetic alignment of drawer fronts and reducing the complexity of accessing the adjusting mechanism.
Implementation Method 1
the actuating element (4) has a spiral worm (7) in engagement with a corresponding latching means (8) on the support foot (6)
Implementation Method 2
In order, however, to achieve a self-locking heightwise adjustment option, it is preferable that at its end remote from the drawer interior the actuating element (4) has a spiral worm (7) which is in engagement with a corresponding latching means (8) on the support foot (6)

AI summary
The invention relates to a drawer frame including an adjusting device for raising and lowering the drawer frame relative to a drawer pull-out guide. The adjusting device, which is arranged substantially inside the drawer frame, has an actuating element accessible from the drawer interior, in the region of a lateral inner surface of the drawer frame facing the drawer interior.
