Drawer Inner Sliding Rail Lock Structure for One-Handed Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sliding track assemblies for drawers are inconvenient to detach due to the need for bilateral hand operation and risk of damaging locking bars, and they have complex structures that increase manufacturing costs and installation complexity.
Innovation Solution
An inner sliding rail mounting structure with a control plate, slide, carriage, and spring member that allows easy engagement and disengagement of the inner sliding rail from the intermediate sliding rail, enabling single-handed operation and reducing manufacturing complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking bar with torsional spring is used for engagement, then the sliding track assembly can be secured, but the detachment operation becomes inconvenient and may damage the locking bar
Solution Approach 1:
The locking mechanism is segmented into a locking bar for engagement and a control plate with slide for detachment. The control plate is pivotally connected to the inner sliding rail and can be rotated to control the locking bar's engagement state, separating the engagement function from the detachment operation.
Solution Approach 2:
The control plate acts as an intermediary between the user's manual operation and the locking bar. By rotating the control plate, the user indirectly controls the locking bar's movement, making detachment easier and preventing direct damage to the locking bar.
2Ease of operation
If multiple locating members and control bars are used for disengagement, then the sliding rail can be detached, but the structure becomes complicated and manufacturing cost increases
Solution Approach 1:
Multiple functions (locking, unlocking, controlling) are merged into a single control plate structure. The control plate integrates the slide mechanism and the control lever function, eliminating the need for separate control bars and multiple locating members.
Solution Approach 2:
The control plate serves multiple functions: it controls the locking bar engagement, guides the slide movement, and provides a user interface for operation. This multi-functional design simplifies the overall structure while maintaining disengagement capability.

Function Achieved in This Case
The solution simplifies the operation and structure, reducing labor and manufacturing costs while allowing easy left- or right-handed use, ensuring safe detachment without damaging components.
Implementation Method 1
a spring member (39) positioned in a longitudinal positioning groove (36) of the carriage (3), having a front end (391) stopped at a front side (361) of the longitudinal positioning groove (36) and a rear end (392) sleeved onto a backwardly extending pin (41) and stopped against a front side of the guide block (4)

AI summary
A inner sliding rail mounting structure is disclosed to include a control plate pivoted with a front side thereof to an inner sliding rail of a sliding track assembly for engagement with a stop block of an intermediate sliding rail of the sliding track assembly to secure the inner sliding rail to the intermediate sliding rail, a slide pivoted to the rear side of the control plate and coupled to the inner sliding rail by a slip joint for biasing the control plate to disengage the control plate from the stop block of the intermediate sliding rail for allowing removal of the inner sliding rail from the intermediately sliding rail, and a carriage affixed to the rear side of the slide and holding a spring member against a locating block at the inner sliding rail for pulling by the user to force the slide to bias the control plate.
