Pivoting Furniture Closure Rail for Sealed Vehicle Cabinets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing furniture closure systems in the vehicle sector, particularly in climate cabinets, face challenges with secure sealing, easy opening, and efficient cleaning due to the limitations of magnetic seals and bellows seals, which are costly and prone to thermal bridges and bacterial contamination.
Innovation Solution
A furniture lock with a profile rail equipped with a spring-elastic seal and a locking element that pivots from an open to a closed position, ensuring secure locking without additional spring elements, and can be easily cleaned, using materials like elastomeric plastic or foam rubber for enhanced sealing and insulating properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If magnetic seals are used for furniture closure, then secure sealing is achieved, but cost increases and thermal bridges are created
Solution Approach 1:
The patent replaces magnetic seals with a purely mechanical locking system consisting of a profile rail, locking element, and spring element. The spring element provides the necessary force to engage the locking element with the counter surface, eliminating the need for magnetic components while achieving secure sealing through mechanical interlocking.
Solution Approach 2:
The invention changes the sealing mechanism from magnetic field-based to spring-force-based. The spring element is designed with specific elastic properties to provide sufficient closing force for secure sealing, while the locking element geometry is optimized to engage reliably with the counter surface, maintaining sealing security without thermal bridges.
2Reliability
If bellows seals are used for furniture closure, then secure sealing is achieved, but cleaning difficulty increases and bacterial contamination risk arises
Solution Approach 1:
The patent extracts the seal from the complex bellows structure and places it on a smooth, flat profile rail surface. The seal is positioned between the profile rail and the counter surface, creating a simple contact interface that is easy to clean and maintain, while still providing secure sealing through the spring element's closing force.
Solution Approach 2:
Instead of using a complex bellows structure that encloses the seal, the invention inverts the approach by using a flat profile rail with a seal that contacts a smooth counter surface. This reversal simplifies the cleaning process, as the seal surface is now accessible and can be easily wiped down without disassembling complex structures.
3Reliability
If additional spring elements are added for locking, then secure locking is achieved, but device complexity increases
Solution Approach 1:
The patent merges the spring element directly into the profile rail structure, eliminating the need for separate mounting components. The locking element is integrated with the door or drawer, and the spring element is positioned within the profile rail to directly engage the locking element with the counter surface, achieving secure locking with minimal additional components.
Solution Approach 2:
The profile rail serves multiple functions: it provides the mounting structure for the seal, houses the spring element, and acts as the locking mechanism interface. The spring element simultaneously provides both sealing force and locking force, combining multiple functions into a single component to reduce overall system complexity.
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 provides a cost-effective, secure, and easily cleanable closure system that minimizes thermal bridges and bacterial entry, while maintaining efficient sealing and insulating properties, suitable for various climate conditions.
Implementation Method 1
the profile rail is designed to accommodate a seal with a spring effect and that the profile rail with the seal, which serves as a spring element for the closed position, and with the locking element can be adjusted about a horizontal axis. Due to its spring tension, the seal presses the locking element into the locking position
Implementation Method 2
For furniture locks of climate cabinets, it is advisable to use a spring-elastic seal with insulating properties

AI summary
The invention relates to a furniture closure for doors, shutters and drawers, in particular for cabinets and the like in the vehicle sector. In order to provide a furniture closure which, while being particularly straightforward to design and produce, ensures sealed and secured closure of doors, shutters (3) and drawers, a profile rail (5) having a seal (6), a grip strip and a locking element (7) is arranged along the peripheral region thereof and can be pivoted about a horizontal axis (23). The seal (6) has a spring force which retains the locking element (7) in the closure position and can be compressed for the opening position.
