Window Fitting Sliding Piece for Compact Tilt-Turn Corner Drive
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fittings for tilt and turn windows and doors, particularly those with corner drives, face challenges in space efficiency, especially with narrower designs, as they occupy too much space and are not adaptable for all sizes.
Innovation Solution
A sliding piece with a drive rod connection and locking pin that extends transversely, combined with a tilting pin for unlocking and locking, allowing for both turn and tilt operations while minimizing space usage, utilizing existing locking pieces and allowing for adjustable stops to accommodate various window or door sizes.

Engineering Contradiction Analysis
1Volume of moving object
If corner drives are used in existing fittings for tilt and turn windows, then locking and tilting functions are achieved, but the fitting occupies too much space and is not adaptable for narrow windows or doors
Solution Approach 1:
The fitting is divided into separate functional components: a corner component with housing and sliding piece, and separate closing pieces (locking piece and tilting piece) that can be independently positioned on the window frame. This segmentation allows each component to be optimized for minimal space while maintaining full functionality.
Solution Approach 2:
The sliding piece integrates multiple functions: it carries both a locking pin (extending transversely) and a tilting pin (extending in displacement direction), allowing a single component to perform both locking and tilting operations. The closing pieces can be assigned to different locations on the window frame, making the system adaptable to various window sizes and configurations.
2Volume of moving object
If a sliding piece with transverse locking pin and longitudinal tilting pin is used, then locking and tilting functions are achieved with minimal space, but the mechanism complexity increases
Solution Approach 1:
The locking pin and tilting pin are integrated into a single sliding piece that moves linearly within the corner component housing. This merging of functions into one component reduces the number of separate mechanisms needed, thereby reducing overall complexity despite the multi-functional capability.
Solution Approach 2:
Instead of having separate mechanisms for locking and tilting that operate independently, the invention inverts the approach by having a single sliding piece that performs both functions through its position. The locking pin engages/disengages and the tilting pin engages/disengages based on the same linear displacement, simplifying the control mechanism.

AI summary
The invention relates to a fitting for a window, a door or the like, comprising a corner component that can be assigned to a frame of a leaf, sash or casement and two closing pieces that can be assigned to an outer frame, wherein the corner component has a housing with a sliding piece that can be displaced linearly thereupon in the direction of displacement. It is provided that the sliding piece (8) has a drive-rod linking connection (17) or a gear-mechanism linking connection and a closure pin (20), which extends transversely in relation to the direction of displacement (10) and to which one of the closing pieces (3, 4) is assigned, and that the sliding piece (8) has a tilting pin (32), which extends in the direction of displacement (10) and forms a release element and to which the other of the closing pieces (4, 3) is assigned.
