Door Hinge Receiving Body with Adjusting Spindles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door hinges with receiving devices require a deep installation space and complex structural designs to accommodate lateral and vertical adjustments, making them bulky and difficult to integrate into thinner door frames.
Innovation Solution
A simplified door hinge design featuring a receiving body composed of two riveted brackets with rotatably mounted adjusting spindles that pass through threaded holes in the strap tab, eliminating the need for clamping devices and allowing direct weight transfer from the door leaf to the spindles, thereby reducing the structural height and installation depth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a clamping device with multiple plates and spindles is used to allow adjustment of the receiving body, then the adjustment capability is improved, but the installation depth requirement increases to 22-25 mm
Solution Approach 1:
The invention extracts and eliminates the clamping device from the receiving device. Instead of using multiple clamping plates and spindles to hold the hinge flap, the hinge flap is directly integrated into the receiving body through threaded holes, removing the unnecessary clamping mechanism while preserving adjustment capability through the spindles that engage with the hinge flap's threaded holes.
Solution Approach 2:
The invention merges the hinge flap with the receiving body by integrating it directly into the receiving body structure. The hinge flap becomes an integral part of the receiving body through threaded connections, eliminating the need for separate clamping plates and reducing the overall structural height while maintaining adjustment functionality.
2Reliability
If a clamping device with multiple components is used to secure the hinge flap, then the securing reliability is improved, but the device complexity increases
Solution Approach 1:
The invention removes the complex clamping device consisting of multiple plates and fastening elements. The hinge flap is directly integrated into the receiving body through threaded holes, eliminating the need for separate clamping plates, spindles, and fastening elements while maintaining secure attachment through the simplified direct integration mechanism.
Solution Approach 2:
The invention combines the hinge flap and receiving body into a single integrated structure. The hinge flap is directly formed as part of the receiving body and secured through threaded holes, merging multiple components into one unified structure that is both simpler and equally reliable.
3Manufacturing precision
If the receiving body is designed with multiple clamping plates and spindles for adjustment, then the adjustment precision is improved, but the structural height increases
Solution Approach 1:
The invention extracts and eliminates the multiple clamping plates from the design. The receiving body consists of a single piece with integrated hinge flap and threaded holes, removing the stacked plate structure that contributed to increased height while maintaining adjustment precision through the spindle mechanism that engages with the hinge flap's threaded holes.
Solution Approach 2:
The invention merges the hinge flap with the receiving body into a single integrated component. This consolidation eliminates the need for multiple stacked clamping plates, significantly reducing the structural height while preserving adjustment precision through the threaded connection system.
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 compact design enables the receiving device to be installed in a cutout within the door leaf, providing adjustable and stable door hinge functionality with reduced depth requirements, suitable for various door types including rebated and butt doors.
Implementation Method 1
The adjusting spindles pass through threaded holes in the strap tab inserted in the receiving body, the position of which can be adjusted by turning the adjusting spindle
Implementation Method 2
the receiving body consists of two brackets riveted together

AI summary
The invention relates to a door hinge, particularly for building entrance doors, comprising a pivot joint (1) with a hinge leaf (2) and a receiving device (3) for receiving the hinge leaf (2). The receiving device (3) has at least one fastening element (4, 4') and a receiving body (5) adjustable relative to the fastening element (4, 4'). According to the invention, the receiving body (5) consists of two riveted brackets (6, 7) between which two adjusting spindles (8) are rotatably mounted. The adjusting spindles (8) engage threaded bores in the hinge leaf (2) integrated in the receiving body (5), the position of which can be adjusted by rotating the adjusting spindles (8).
