Concealed Hinge With Fixed-Body Slide Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing concealed hinges for doors and windows have complex structures on the movable sash, leading to reduced stability and difficulty in precise adjustments, especially when positioned at low heights, resulting in reduced functionality and precision over time.
Innovation Solution
A concealed hinge design with adjustable mechanisms on the fixed body, utilizing a slide with a rotary element for horizontal axis adjustments, allowing precise centring and compression adjustments without complicating the movable sash's supporting parts, maintaining a compact and reliable structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If threaded adjustment elements are positioned on the second movable body for adjusting sash height, then height adjustment functionality is provided, but the structure becomes complex and stability is reduced
Solution Approach 1:
The patent inverts the conventional approach by positioning the adjustment mechanism on the fixed body instead of the movable body. The first adjustment means is configured on the first fixed body to adjust the position of the first axis of articulation, rather than having adjustment elements on the movable body to adjust sash height. This inversion simplifies the overall structure while maintaining adjustment functionality.
Solution Approach 2:
The patent segments the adjustment functionality into separate means: first adjustment means on the fixed body for horizontal axis adjustment, and second adjustment means on the movable body for vertical axis adjustment. This segmentation allows each adjustment mechanism to be optimized independently, with the fixed body adjustment providing structural stability and the movable body adjustment providing precise vertical control.
2Adaptability or versatility
If adjustment units are positioned on the second movable body for horizontal axis adjustment, then centring adjustment is provided, but handling becomes difficult at low heights
Solution Approach 1:
The patent applies inversion by placing the first adjustment means (for horizontal axis adjustment) on the first fixed body rather than on the movable body. This allows the adjustment mechanism to be accessed and operated from the fixed frame side, making it easier to handle even when the door or window is positioned at low heights, as the adjustment mechanism remains accessible from the stationary frame.
3Adaptability or versatility
If multiple adjustment elements are added to the movable body, then adjustment functionality is expanded, but stability and precision are reduced over time
Solution Approach 1:
The patent inverts the placement of the first adjustment means from the movable body to the fixed body. This inversion reduces the number of moving parts and adjustment elements on the movable body, thereby improving stability and precision over time while still providing comprehensive adjustment functionality through the combination of fixed body horizontal adjustment and movable body vertical adjustment.

Function Achieved in This Case
Enables quick, precise, and secure adjustments of the movable sash in horizontal axes, improving stability and ease of use while maintaining a compact and reliable structure, reducing the complexity and instability issues of prior art solutions.
Implementation Method 1
a rotary element (13) configured for moving the slide (12), in both directions and along the first horizontal axis (XR1), in such a way as to vary the distance between the adjustment axis (X12) and the first axis of articulation (X1) along the first horizontal axis (XR1)

AI summary
Described is a hinge for doors or windows comprising: a first fixed body (5) associated with a fixed frame (1) and having a first axis (X1) of fixed articulation and a slot (6) made parallel to the axis (XC) of longitudinal extension of the first fixed body (5); a second movable body (7) connected to a movable sash (2); a first lever (8) having a first end articulated to the first fixed body (5) about the first axis (X1) of fixed articulation, a second end articulated to the second movable body (7), defining a second axis (X2) of articulation, and an intermediate zone; a second lever (9) having a first end articulated inside the slot (6) of the first fixed body (5) to define a third slidable axis (X3) of articulation, a second end articulated to the second movable body (7) defining a fourth axis (X4) of articulation and an intermediate zone; the first (8) and the second (9) levers are articulated to each other in the corresponding intermediate zone to define a fifth axis (X5) of shared articulation; means (10, 11) for adjusting at least one between the first axis (X1) of articulation and the third slidable axis (X3) of articulation along at least a first horizontal axis (XR1) parallel to the axis (XC) of longitudinal extension of the first fixed body (5) or a second horizontal axis (XR2) perpendicular to the axis (XC) of longitudinal extension of the first fixed body (5); the adjustment means (10) comprising a slide (12) positioned on the first fixed body (1) and having a first constraining portion for the first axis (X1) of articulation and a second portion connected to an adjustment axis (X12), parallel to the first axis (X1) of articulation, using a rotary element (13) configured for moving the slide (12), in both directions and along the first horizontal axis (XR1), in such a way as to vary the distance (D) between the adjustment axis (X12) and the first axis (X1) of articulation along the first horizontal axis (XR1), in both directions.
