Hidden Hinge Arrangement With Locking Projection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hinge arrangements for door and window sashes, particularly those with metal profiles and multi-chamber glass panes, are difficult to install as they require holding a heavy sash while inserting and fastening all hinge levers, and they lack ease of adjustment after fastening.
Innovation Solution
A hinge arrangement featuring a clamping member with a recess for a locking projection and a C-shaped locking element with a retaining surface, which includes locking means to prevent displacement, allowing for vertical adjustment of the sash without needing to relieve the entire sash, and includes a rotatable element for blocking hinged movement, enabling easier assembly and adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional hinge arrangements are used for mounting heavy door sashes, then the sash can be securely mounted, but the installation becomes difficult as the heavy sash must be held in hands while hinge levers are inserted and fastened
Solution Approach 1:
The hinge lever is pre-inserted into the clamping member before the heavy sash is mounted. The locking projection is positioned in the recess beforehand, and the locking means are prepared in advance. This preliminary arrangement of components eliminates the need to hold the heavy sash while manipulating multiple hinge levers during installation.
2Ease of operation
If traditional hinge arrangements are used, then the sash can be mounted, but adjustment of sash position after fastening is difficult
Solution Approach 1:
The locking means are designed to be reversible and adjustable. The locking projection can be disengaged from the locking element, allowing the hinge lever to be repositioned within the clamping member. After adjustment, the locking projection can be re-engaged with the locking element to secure the new position, enabling post-installation adjustment without complete disassembly.
3Stability of the object's composition
If multiple hinge levers are used for secure mounting, then the sash is stable, but the complexity of managing all hinge levers simultaneously increases
Solution Approach 1:
The locking projection and locking element combine multiple locking functions into a single integrated mechanism. Instead of managing separate locking operations for each hinge lever, the locking projection simultaneously engages with the locking element to secure the hinge lever in place, simplifying the installation process while maintaining stability.

AI summary
The present invention relates to a hinge arrangement (1), preferably a hidden hinge arrangement, comprising a first hinge member (2) connected in a hinged manner to a second hinge member (3) provided with a hinge lever (35) and a clamping member (33) with a slot (331) into which said hinge lever (35) is inserted in the direction substantially perpendicular relative to the axis (A) of the hinge arrangement (1), and mounting means (335) for mounting said hinge lever (35) in the clamping member (33) of the second hinge member (3). In order to enable an ease adjustment of a sash (5) position relative to a frame (4) after fastening the sash (5), the clamping member (33) has at least one recess (334) open on the side of the hinge lever (35) insertion, and the hinge lever (35) has at least one locking projection (353) located in said recess (334) of the clamping member (33), wherein the second hinge member (3) has additionally at least one locking member (34) provided with a retaining surface (342) for said locking projection (353) of the hinge lever (35), and the locking element (34) and/or the clamping member (33) is/are provided with locking means (344, 336) blocking a displacement of the locking element (34) along the direction of the hinge lever (35) insertion.
