Hinge Bracket for Thin Glass Doors Using End-Surface Recess
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hinges with recessed portions for articulation joints face challenges in attaching to thin doors like glass doors due to increased width requirements, making it difficult to secure the door side member effectively.
Innovation Solution
A hinge design featuring a main body side member and a door side member with an outer shell portion, a first holding piece, and a second holding piece that sandwich the door in its thickness direction, allowing the articulation joint to be received within the door's surface, and a hinge bracket for secure attachment using a fixing member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the main body side member and the door side member are provided with recessed portions to receive the articulation joint, then the design is improved and security performance is improved, but the widths of the main body side member and the door side member become large
Solution Approach 1:
The invention relocates the recessed portion from the side surface of the door side member to its end surface, utilizing a different spatial dimension. This allows the articulation joint to be received at the end of the door side member rather than along its side, thereby reducing the width requirement while maintaining the security benefit of concealing the articulation joint when the door is closed.
2Reliability
If the recessed portion is provided on the side surface of the door side member, then the articulation joint can be concealed at closed position, but it becomes difficult to attach to thin doors such as glass doors
Solution Approach 1:
The invention moves the recessed portion from the side surface to the end surface of the door side member, changing the spatial arrangement from a lateral configuration to an end-facing configuration. This dimensional change enables the hinge to be mounted on thin doors like glass doors where side surface mounting would be impractical, while still achieving concealment of the articulation joint at the closed position.
3Shape
If the articulation joint is received in the recessed portion of the door side member, then the design of the door is improved, but the width of the door side member increases
Solution Approach 1:
The invention repositions the recessed portion from the side surface to the end surface of the door side member, utilizing the end surface dimension instead of the side surface dimension. This allows the articulation joint to be received in a location that does not increase the width of the door side member, thereby maintaining a sleek door design while still achieving the aesthetic benefit of concealing the articulation joint when closed.

AI summary
Provided are a hinge capable of attaching a door side member having a recessed portion to receive an articulation joint in an end surface of a thin door such as a glass door and a hinge bracket. The hinge of the present invention includes a main body side member to be attached to a main body; and a door side member to be attached to a door, rotatably connected to the main body side member via an articulation joint and having a recessed portion to receive at least a part of the articulation joint. The door side member includes an outer shell portion, a first holding piece projecting from the outer shell portion, and a second holding piece for sandwiching the door with the first holding piece in a thickness direction of the door within a range of the outer shell portion in the thickness direction of the door.
