Balcony Glazing Hinge Pin Structure for Low-Deflection Sliding Windows
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing balcony glazing arrangements face issues with window deflection and strain on carriages and frame components due to weight when turned open, affecting functionality, appearance, and increasing material and assembly costs.
Innovation Solution
A continuous hinge pin system is used, with non-rotatably connected ends to the frame head and sill, allowing contraction onto a vertical side rail, minimizing play and eliminating the need for a vertical frame jamb, and utilizing bushings and fasteners to stabilize and reduce friction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a sturdy frame column is used to connect frame head and frame sill, then deflection is minimized, but glazed area is reduced and appearance is affected
Solution Approach 1:
The patent extracts the frame column from the window frame structure and relocates it to the window sash as a vertical side rail. This allows the frame head and frame sill to be connected directly through the hinge pin without requiring a protruding frame column, thereby maintaining stability while preserving the glazed area and improving appearance.
Solution Approach 2:
Instead of adding a frame column to the window frame to provide stability, the patent inverts the approach by making the window sash (with vertical side rail) the load-bearing element that connects to the frame head and frame sill. This reverses the traditional structural arrangement and eliminates the need for a protruding frame column.
2Stability of the object's composition
If a vertical frame jamb is added to connect hinge side ends, then stability is improved, but material and assembly costs increase
Solution Approach 1:
The patent merges the function of the vertical frame jamb with the vertical side rail of the window sash. The vertical side rail serves dual purposes: it provides structural connection between frame head and frame sill, and it forms part of the window sash assembly. This consolidation eliminates the need for a separate frame jamb, reducing material and assembly complexity.
3Ease of operation
If hinge pin allows rotation, then opening and closing is enabled, but play and imprecision occur
Solution Approach 1:
The patent implements a dynamic hinge pin system that allows rotation during window operation but maintains precision through controlled constraints. The hinge pin rotates within the vertical side rail to enable opening and closing, while bushings and fasteners provide dynamic stabilization to minimize play and maintain manufacturing precision throughout the motion range.
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
This design enhances the appearance, functionality, and reduces material and assembly costs by minimizing deflection and improving the feel of opening and closing operations.
Implementation Method 1
the hinge arrangement comprises a continuous hinge pin, which rotatably runs through said vertical side rail from the frame head to the frame sill
Implementation Method 2
a first one of the ends of the hinge pin is arranged to render application of a fastener possible, which, when tightened, contracts the frame head and the frame sill onto said vertical side rail

AI summary
A balcony glazing arrangement (1) comprising at least one horizontally slidable window (2), which comprises a sliding window frame (10) and a window sash (30), which is openable mounted on the window frame (10) by means of a vertically oriented hinge arrangement (40). The hinge arrangement (40) comprises a continuous hinge pin (41), which rotatably runs through a vertical side rail (33) of the window sash (30) from a window frame head (11) to a window frame sill (12). The hinge pin (41) comprises ends (41', 41''), which are non-rotably connected to the frame head (11) and the frame sill (12), wherein a first one (41') of the ends of the hinge pin (41) is arranged to render application of a fastener (42) possible, which, when tightened, contracts the window frame head (11) and the window frame sill (12) onto said vertical side rail (33).
