Window Fitting with Segmented Control Path for Tilt-Slide Transition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window and door fittings do not allow for both tilting and sliding movements of a sash around a horizontal pivot axis, limiting the functionality and versatility of window and door systems.
Innovation Solution
A fitting that includes a stay rod connected to both the sash and a glider or carriage, featuring a control part with a control contour and a bolt that can be moved by an actuating element to allow controlled tilting and sliding movements of the sash.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional fitting with a stay rod and control contour is used, then the sash can be parked parallel to the frame plane, but the sash cannot be tilted away from the frame
Solution Approach 1:
The control contour is divided into two distinct sections: a first control section for tilting movement and a second control section for sliding movement. The control pin moves along different sections depending on the desired operation, enabling both tilting and sliding capabilities through a segmented control path rather than a single continuous contour.
Solution Approach 2:
A bolt is introduced as an intermediary element that can be positioned in a blocking position to prevent the control pin from moving along the entire control contour. This intermediary component allows selective restriction of movement paths, enabling the system to switch between tilting and sliding operations by controlling whether the control pin can transition between the first and second control sections.
2Ease of operation
If the control pin is allowed to move freely along the control contour, then the sash can tilt open, but the movement from sliding position to closing position becomes uncontrolled
Solution Approach 1:
The bolt is designed to be dynamically positionable between a blocking position and a release position. When blocking, it provides controlled movement by preventing the control pin from moving freely. When released, it allows free movement for tilting operations. This dynamic adjustment of constraints enables both controlled and free movement modes as needed.
Solution Approach 2:
The bolt is positioned in advance to prevent unwanted movement of the control pin. By placing the bolt in the blocking position before the control pin can move along the control contour, the system prevents uncontrolled movement from the sliding position to the closing position, ensuring reliable controlled movement until the bolt is intentionally released.

AI summary
The invention relates to a fitting (10) for connecting a sash of a window, door, or the like to its frame. The fitting (10) enables the sash—depending on the coupling of the sash to the frame by a further fitting—to either be tilted or opened parallel to the main plane of the frame and then moved parallel to the main plane of the frame. For this purpose, the fitting (10) has a tilting scissor mechanism (16) which is guided by a control pin (24) in a control element (14) that can be connected to the frame. A locking bolt of the control element limits the travel of the control pin (24) during the closing movement of the sash from a position displaced parallel to the main plane of the frame. This enables a controlled and defined arc-shaped closing movement.In contrast, an actuating element connected to the tilting scissor mechanism (16) allows the latch to be repositioned when the sash is to be tilted, in order to permit a greater movement of the control pin (24) and thus a straight pivoting of the sash into a tilted opening position. The actuating element is preferably designed as a slider for moving the sash or is connected to a slider for moving the sash.
