Securing device for a panel of a drawer on a frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening devices for drawer panels risk the panel slipping off when the connecting elements are unlocked, requiring manual holding to prevent falling, and lack a simple method for detachment.
Innovation Solution
A fastening device with a panel support and adapter featuring a catching device and latching elements that allow the panel support to be slid onto the adapter, enabling linear displacement when released, and a method that involves unlocking the connecting elements and lifting the panel support to prevent slipping, allowing for secure detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the connecting elements are unlocked to enable detachment, then the panel support can be removed, but the panel support slips off the adapter and must be held manually
Solution Approach 1:
The detachment process is divided into two independent stages: first unlocking the connecting elements (catch devices), then lifting the panel support to disengage the latching elements. This segmentation allows each stage to be controlled separately, preventing accidental slippage while maintaining ease of operation.
Solution Approach 2:
The latching elements (retaining lugs and retaining webs) are pre-positioned to engage automatically when the panel support is mounted. During detachment, the lifting action is prepared in advance to disengage these latching elements before complete removal, ensuring the panel support remains controlled throughout the process.
2Device complexity
If a simple fastening structure is used, then the device complexity is reduced, but the panel support may fall off when unlocked
Solution Approach 1:
The catching device (with catch and connecting element) and the latching device (with retaining lugs and retaining webs) are merged into a single integrated fastening system. This combination provides both locking and retention functions in one structure, maintaining simplicity while ensuring reliability during the detachment process.
Solution Approach 2:
The latching elements (retaining lugs and retaining webs) act as intermediary components between the panel support and adapter. These intermediaries provide an additional retention mechanism that prevents the panel support from falling off during unlocking, without significantly increasing overall structural complexity.
3Ease of operation
If the panel support is allowed to displace linearly when released, then ease of detachment is improved, but the panel support may slip off in the release direction
Solution Approach 1:
The fastening system transitions from a static locked state to a dynamic controlled release state. The latching elements are designed to disengage smoothly during linear displacement, allowing controlled movement while preventing uncontrolled slippage. The retaining lugs and webs provide dynamic retention throughout the movement process.
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
The solution ensures the panel support remains securely attached during unlocking and allows for easy detachment without the panel falling, simplifying the process and enhancing safety and usability.
Implementation Method 1
at least one retaining lug (619, 629) formed on the adapter and at least one retaining web (76) formed on the panel support (7), which cooperate in such a way that the panel support (7) can be pushed onto the adapter (6)

AI summary
The invention relates to a securing device (10) for securing a panel (2) of a drawer (1) on a frame (4), having at least one panel support (7) arranged on the panel (2) and at least one adapter (6) which is secured in a frame (4) and to which the panel support (7) can be secured, wherein the adapter (6) has at least one catching device, by means of which a respective connection element (72) arranged on the panel support (7) can be fixed to the adapter (6) in an assembly position. The panel support (7) can be pushed onto the adapter (6) of the frame (4) in the longitudinal direction of the frame, and an interacting locking device, which is used to movably hold the panel support (7) on the adapter (6) in a linearly limited manner in the release direction (L) when the catching device(s) is/are released, is provided between a lateral wall (61, 62) of the adapter (6) and a lateral wall (71, 75) of the panel support (7), said panel support lateral wall being arranged opposite the adapter lateral wall. The invention additionally relates to a method for releasing a panel (2) from a frame (4) with such a securing device (10).
