Lift-Slide Fitting with Frame-Mounted Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lift-slide element fitting arrangements require a wide sash edge and significant installation space for the rail strip, limiting the transparent area and efficient movement.
Innovation Solution
The fitting arrangement relocates adjustment mechanisms to the frame side, eliminating the need for adjustable elements on the sash and using a rail bar that moves perpendicularly between lowered and raised positions, coupled with levers to redirect movement, allowing a narrower sash edge and increased transparency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If adjustment mechanisms are installed on the sash side, then the sash can be adjusted and moved, but the sash edge becomes wide and installation space is consumed
Solution Approach 1:
The patent inverts the conventional arrangement by moving the adjustment mechanism from the sash side to the frame side. The rail bar is now adjusted by the frame-mounted adjustment mechanism rather than by a sash-mounted mechanism, thereby eliminating the need for wide sash edges while preserving full adjustability functionality.
Solution Approach 2:
The adjustment mechanism is extracted from the sash structure and relocated to the frame structure. This separation removes the conflicting requirement for installation space on the sash, allowing the sash edge to be minimized while the adjustment functionality remains intact through the frame-mounted mechanism.

3Ease of operation
If the rail bar moves along the direction of travel, then adjustment is possible, but installation space is required for movement
Solution Approach 1:
The patent changes the dimension of movement from longitudinal (along the direction of travel) to transverse (perpendicular to the direction of travel). The rail bar is moved sideways by the adjustment mechanism rather than along its length, eliminating the need for installation space in the direction of travel while maintaining full adjustability.
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 minimizes the sash edge width, enlarges the transparent area, and reduces installation space requirements while enabling smooth, low-friction movement of the lift-slide element.
Implementation Method 1
the deflection element comprises at least one lever
Implementation Method 2
a roller can be provided on the sash side, against which the track can act in the raised position of the rail bar

AI summary
The invention relates to a fitting arrangement (10) for a lift-and-slide element (12) such as a lift-and-slide door or a lift-and-slide window which comprises a fixed frame (14) and a leaf/sash which can be displaced in a displacement direction (41) relative to the frame (14) in a raised position along a lower running track, wherein an adjustment element (40) is provided which is mounted so as to be movable in a displacement direction (41) between a lowering position and a raising position, and a rail strip (38) having the running track is provided on the frame side and is mounted so as to be adjustable in a movement transversely to the displacement direction (41) between a lowered position and a raised position, wherein the adjustment element (40) has arranged thereon at least one deflection element (54) by means of which a movement of the adjustment element (40) from the lowering position into the raising position can be deflected into an adjustment of the rail strip (38) from the lowered position into the raised position. The invention further relates to a lift-and-slide element having such a fitting arrangement.
