Corner Window Sliding Sashes Dynamic Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing corner-arranged windows and doors often inadequately seal when locked, failing to meet modern requirements for thermal insulation and burglary security.
Innovation Solution
A window or door design featuring a fixed frame with intersecting main frame planes, where wings can be moved transversely into sliding positions, providing enhanced windtightness and burglary protection while allowing a large passage opening, with drive rod arrangements and handles for controlled movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sliding panels are arranged at an angle to each other and locked against a corner post, then the window can be closed in a corner position, but the sealing performance is inadequate and burglar resistance is insufficient
Solution Approach 1:
The patent implements a dynamic corner post mechanism that can switch between two states: (1) coupled to the first sliding panel to provide anchoring and sealing when locked, and (2) uncoupled to allow the first sliding panel to be moved independently for opening. This dynamic coupling/uncoupling capability resolves the contradiction by enabling the system to adapt its configuration based on whether it needs to seal securely or allow operation.
Solution Approach 2:
The corner post is functionally segmented into a fixed portion (attached to the frame) and a movable portion (coupled to the first sliding panel). This segmentation allows the movable portion to be detached from the fixed portion, enabling the first sliding panel to operate independently while maintaining the sealing function when coupled. The segmentation enables both secure sealing and operational flexibility.
2Ease of operation
If sliding panels are designed to move linearly parallel to the track, then the structure is simple, but a large passage opening cannot be created
Solution Approach 1:
The patent introduces a second degree of freedom by allowing the first sliding panel to move not only linearly along the track (first dimension) but also independently of the corner post (second dimension). This enables the panel to be positioned in multiple locations along the track, creating variable passage openings. The additional dimensional freedom allows large openings to be created without significantly complicating the basic linear sliding mechanism.
3Reliability
If the corner post is coupled to one sliding panel, then burglar resistance is improved, but the other sliding panel cannot be moved independently
Solution Approach 1:
The corner post's coupling to the first sliding panel is made dynamic rather than permanent. The coupling mechanism allows the corner post to be attached to the first sliding panel for enhanced security when needed, but can be uncoupled to allow independent movement of the first sliding panel. This dynamic adaptability resolves the contradiction by enabling the system to switch between secured and flexible operational modes.
Solution Approach 2:
The corner post is pre-configured with the capability to couple to the first sliding panel, but remains uncoupled during normal operation to allow independent movement. When security is needed, the coupling action is performed preliminarily to prepare for enhanced burglar resistance. This preliminary configuration capability allows the system to maintain adaptability while having the option to improve security when required.

AI summary
The invention relates to a window or door (36) and a building (82) with such a window or door (36). The window or door (36) has a fixed frame (38) which is shaped horizontally to form a corner of the building. A first sash (10) and a second sash (48) are arranged in the fixed frame (38). Both sashes (10, 48) can be moved from their locked position to their sliding position by means of a handle (14, 50). During this movement, the first sash (10) preferably remains parallel to a first main frame plane (18) of the fixed frame (38), and the second sash (48) preferably remains parallel to a second main frame plane (56) of the fixed frame (38). In the sliding position, both sashes (10, 48) can be moved into their respective open positions, parallel to their respective main frame planes (18, 56).The fixed frame (38) can be configured as an internal corner of the building (82) or as an external corner of the building (82). The two leaves (10, 48) can be directly connected to each other, in particular locked to each other, at the corner by moving both leaves (10, 48) into the locking position. One of the leaves (10, 48) can have a locking piece (76) to which the other leaf (10, 48), in particular at its end face, can engage.
