Drawer Hooking Assembly With Longitudinal Front Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hooking devices for connecting drawers to longitudinal guides lack the ability to adjust the front position in the longitudinal direction, leading to potential aesthetic issues with self-closing and push-type drawer systems, requiring additional adjustment devices that increase complexity and cost.
Innovation Solution
A hooking device with a support body that includes an oscillating command lever and adjustable parts allowing for longitudinal, height, and lateral adjustments, featuring a second part of the body that can be slidably positioned in the longitudinal direction, and additional adjustment means such as a wedge-shaped element and manual gripping elements for precise positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If separate regulating devices are applied between the frontal part and lateral walls of the drawer to adjust the position of the front part in the longitudinal direction, then the positioning precision of the drawer front is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines the longitudinal adjustment function into the existing hooking device structure by making the support body adjustable in the longitudinal direction. The support body can be positioned at different locations along the guide's travel path, integrating front adjustment capabilities without requiring separate regulating devices between the frontal part and lateral walls of the drawer.
Solution Approach 2:
The support body is designed with multi-functionality, serving both as the mounting structure for the hooking organ and as the longitudinal adjustment mechanism. By making the support body itself adjustable along the guide, it performs multiple functions: supporting the hooking organ, enabling longitudinal positioning, and eliminating the need for separate adjustment devices.
2Manufacturing precision
If separate regulating devices are applied to adjust the drawer front position in the longitudinal direction, then the aesthetic result is improved, but the manufacturing cost increases
Solution Approach 1:
The patent merges the aesthetic positioning function into the support body structure, which is already part of the hooking device. The support body's ability to be positioned at different longitudinal locations along the guide provides aesthetic adjustment without requiring additional separate regulating devices, thereby avoiding increased manufacturing costs.
Solution Approach 2:
The support body serves as a universal component that provides both structural support and aesthetic positioning capabilities. By making it adjustable in the longitudinal direction, it eliminates the need for separate aesthetic adjustment devices, maintaining cost-effectiveness while achieving the desired aesthetic result.
3Ease of manufacture
If the longitudinal guides are fixed in a non-precise way, then the ease of installation is improved, but the aesthetic result deteriorates due to the drawer front stopping in a detached position
Solution Approach 1:
The patent introduces dynamic adjustability to the support body, allowing it to be positioned at different longitudinal locations along the guide. This dynamic positioning capability compensates for imprecise guide installation, enabling the drawer front to be correctly positioned even when the guide itself is not precisely fixed, thereby maintaining aesthetic results without compromising installation ease.
4Ease of manufacture
If the longitudinal guides are fixed in a non-precise way, then the ease of installation is improved, but the functionality deteriorates due to insufficient space for actuation of the release mechanism
Solution Approach 1:
The adjustable support body provides dynamic positioning capability that ensures adequate space for the release mechanism actuation. Even when the guide is installed in a non-precise manner, the support body can be repositioned along the guide to ensure the drawer front stops at the correct location, maintaining sufficient actuation space for the release mechanism.

AI summary
The hooking device of a drawer to a longitudinal guide, comprises a support body fixable to a front and/or a bottom of the drawer and is provided with an oscillating command lever of a hooking organ of the support body to the guide, the support body exhibiting a first part of body fixable to the drawer and at least one second part of body slidably connected with the first part of body and adjustably positioned at least in the longitudinal direction of the guide, the lever and the hooking organ being solidly constrained to said second part of body in displacement thereof in the longitudinal direction of the guide, at least first adjustment means being further provided for varying a position of said second part of body with respect to the first part of body in the longitudinal direction of the guide for adjusting the position of the drawer with respect to the guide in the longitudinal direction of the guide.
