Drawer Pull-Out Guide With Adjustable Closed-Position Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pull-out slide systems for drawers require a large triggering distance and cannot be easily adjusted or locked from any desired pressure point, making them inflexible and inefficient for various furniture configurations.
Innovation Solution
A pull-out slide system with an adjustable holding mechanism that can be adjusted in depth, height, and sideways, allowing for precise engagement and release of the closed position, enabling operation from any point with low pressure and a short triggering path, and accommodating different furniture widths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed triggering distance is used in the locking unit, then the structure is simple, but the drawer cannot be opened from any desired pressure point and requires large triggering distance
Solution Approach 1:
The patent applies the dynamics principle by making the triggering distance adjustable rather than fixed. The holding means (pin) can be positioned at different locations along the drawer rail, allowing the triggering distance to be dynamically changed based on where the user applies pressure. This enables the drawer to be opened from any desired pressure point while maintaining a relatively simple locking unit structure that only requires positional adjustment of the pin.
2Adaptability or versatility
If the holding means is fixed in position, then the manufacturing is simple, but the closed position cannot be adjusted for different furniture configurations
Solution Approach 1:
The holding means is designed with adjustability along the drawer rail, allowing it to be dynamically repositioned to accommodate different furniture configurations and achieve the desired closed position. This is accomplished through a simple adjustment mechanism that enables the pin to be moved to different locations without requiring complex manufacturing processes or multiple specialized components.
3Reliability
If a multi-part locking unit is used, then the function is reliable, but the adjustment of closed position requires adjusting multiple components
Solution Approach 1:
The holding means (pin) is designed to serve multiple functions: it acts as both the locking element that determines the closed position and the adjustable component for positioning. By combining these functions into a single universal element rather than requiring separate locking and adjustment mechanisms, the patent maintains reliable closed position determination while simplifying the adjustment operation to involve only the pin's repositioning.

AI summary
A holding device engages a unit while either or both of the holding device and the unit can adjust the depth or height on the pull out slide. A cabinet (4) is fastened to a drawer (6) and a center slide (5). The unit defines the closed position of the slide (1) or the drawer.
