Corner connector and frame and folding bed with such a corner connector
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional corner connectors for frame constructions lack multifunctionality, particularly in applications like folding beds, where they cannot efficiently balance forces during folding, adjust height, or integrate adjustable feet and gas pressure springs effectively.
Innovation Solution
A one-piece corner connector that integrates self-tapping screws, U-profile pieces, and a hexagon nut system to securely connect frame members, support gas pressure springs, adjust height, and attach adjustable feet, while maintaining a smooth external frame profile.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional corner connectors are used for frame constructions, then the basic connecting function is achieved, but additional functions such as force balancing, height adjustment, and integrated foot attachment are not available
Solution Approach 1:
The corner connector is designed as a universal component that performs multiple functions: connecting frame members, attaching gas pressure springs for force balancing, providing height adjustment for front panels, and securing adjustable feet. This multi-functional design eliminates the need for separate components for each function, directly addressing the versatility improvement while managing complexity through integration.
Solution Approach 2:
The invention merges previously separate components (corner connector, gas spring attachment, height adjustment mechanism, and foot mounting) into a single integrated corner connector unit. This combining approach achieves multifunctionality by consolidating multiple functions into one component, resolving the technical contradiction between versatility and complexity.
2Adaptability or versatility
If the corner connector integrates multiple functions, then versatility is improved, but the manufacturing complexity increases
Solution Approach 1:
The manufacturing process benefits from merging multiple functions into a single component design. By integrating gas spring attachment points, height adjustment mechanisms, and foot mounting features into the corner connector itself, the patent reduces the number of separate parts that need to be manufactured, assembled, and inventoried, thereby improving ease of manufacture despite the increased functional complexity.
3Adaptability or versatility
If the corner connector is designed with integrated functions, then device functionality is enhanced, but the external frame profile smoothness may be compromised
Solution Approach 1:
The corner connector design applies local quality by concentrating all functional elements (gas spring attachments, adjustment mechanisms, foot mountings) within the corner joint area itself. This allows the main external frame profile to remain smooth and continuous, while the corner regions contain the necessary functional complexity without disrupting the overall aesthetic smoothness of the frame.

AI summary
According to the invention, a one-piece corner connector (1) for connecting two mutually perpendicular frame members (23) comprises a rectangular angle (2) with two angle legs (3), an intermediate plate (4) inserted into the rectangular angle (2) perpendicular to its profile direction, and two mutually perpendicular U-profile connectors (5) with a central and two side legs (6a-6c) for insertion into the end-facing insertion openings of the frame members (23). The central legs (6a) of the U-profile connectors (5) are integrally formed on the intermediate plate (4) and their outer surfaces run parallel to the intermediate plate (4). The one, outer side legs (6b) of the U-profile connectors (5) are each formed on one of the angle legs (3) and run with their outer side parallel to the outer side of the angle leg (3), and the other, inner side legs (6c) of the U-profile connectors (5) are connected to each other by means of a wall element (7) angled from the intermediate plate (4).The middle legs (6a) of the U-profile connectors (5) each have a hole (10).
