Articulated Hinge With Transverse Axle-Bolt Clamping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hinges face difficulties in precise assembly and adjustment of the locking element due to the weight of the door causing transverse loading during assembly and adjustment, making it challenging to maintain the desired angular position without unintentional changes.
Innovation Solution
The hinge design incorporates a clamping screw transverse to the pivot axis, allowing easy adjustment and secure locking of the locking body by clamping the axle bolt ends in axle receptacles, ensuring the desired angular position is maintained without requiring disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the clamping jaws are used to adjust the locking element position, then the locking element can be adjusted to the desired angular position, but the door weight causes transverse loading that makes precise adjustment difficult and allows unintentional position changes
Solution Approach 1:
The patent introduces an intermediary clamping mechanism with clamping jaws that can be opened and closed to grip the locking element. This intermediary device allows the adjustment to be performed in two stages: first positioning the locking element while the clamping jaws are open, then securing it in the desired position by closing the clamping jaws. This eliminates the problem of transverse loading during adjustment while maintaining precision.
Solution Approach 2:
The clamping jaws are designed to be dynamically adjustable between open and closed states. During the adjustment phase, the clamping jaws are open, allowing free movement and precise positioning of the locking element without transverse loading. Once the desired position is achieved, the clamping jaws are closed to secure the position. This dynamic behavior resolves the contradiction between ease of adjustment and positioning precision.
2Adaptability or versatility
If the clamping jaws are opened sufficiently to allow adjustment, then the locking element can be repositioned, but the connection between hinge parts becomes loose and stable
Solution Approach 1:
The connection system transitions dynamically between two states: during adjustment, the clamping jaws are open providing adaptability for repositioning; during normal operation, the clamping jaws are closed providing reliability and stability. This dynamic switching resolves the contradiction between adaptability and reliability.
Solution Approach 2:
The adjustment mechanism allows the locking element to be positioned in the desired angular position before the clamping jaws are closed. This preliminary positioning action ensures that once the connection is secured, the desired position is already established, eliminating the need for loose connections during operation.
3Measurement precision
If the hinge is assembled with the door attached for adjustment, then the actual operating conditions are replicated, but the transverse loading from door weight makes precise adjustment work difficult
Solution Approach 1:
The clamping jaws act as an intermediary that decouples the adjustment process from the load-bearing function. By opening the clamping jaws during adjustment, the locking element can be positioned precisely without the interfering transverse loads from the door weight. The clamping jaws are then closed to transfer the load-bearing function to the secured connection.
Solution Approach 2:
The adjustment process is segmented into distinct phases: positioning phase with clamping jaws open (free from transverse loading), and securing phase with clamping jaws closed (bearing operational loads). This segmentation allows precise adjustment work to be performed under ideal conditions, separate from the harsh operating conditions.

AI summary
The invention relates to a hinge, particularly for glass doors, comprising two hinge parts (11, 12) pivotally connected to one another about a pivot axis (16) of an axle bolt (20), and comprising a locking device (24) acting between the two hinge parts (11, 12), which essentially consists of at least one locking element (25) associated with the first hinge part (11) and movably guided against the action of at least one spring element (27), and a locking body (30) associated with the second hinge part (12) having at least one locking surface (31) cooperating with the locking element (24) in a locking position, wherein the locking body (30) is arranged between two hinge webs (13, 14) formed on the second hinge part (12) coaxially to the pivot axis (16) and can be locked in various angular positions of its locking surface (31). In order to improve such a hinge,that it can be assembled and adjusted more easily than known constructions and that the adjustment found is subsequently reliably maintained, the invention proposes that the closing body (30) is formed by the axle bolt (20), which forms a bearing receptacle (21) for the first hinge part (11) between a first axle bolt end (18) and a second axle bolt end (19), on the circumference of which bearing receptacle the locking surface (31) is formed, wherein the first axle bolt end (18) is rotatably engaged in a first axle receptacle (17a) arranged on the first hinge web (13) of the second hinge part (12) and the second axle bolt end (19) is rotatably engaged in a second axle receptacle (17b) arranged on the second hinge web (14) of the second hinge part (12), wherein at least one of the axle bolt ends (18, 19) is provided with a threaded bore (33) arranged transversely to the pivot axis (16) and a in this for clamping the axle bolt end (18,19) is provided with a clamping screw (34) screwed into the associated axle receptacle (17), which is adjustable from an outer side of the second hinge part (12) in the threaded bore (33). With the invention, the adjustment and locking of the locking body relative to the second hinge part in various angular positions can be achieved very simply and quickly by adjusting the clamping screw, which is received transversely to the pivot axis in the threaded bore in the axle bolt end, from the outer side of the hinge part in such a way that the axle bolt end clamps itself inside the axle receptacle receiving it, thus preventing the initially existing rotational mobility.
