Perpendicular Mounting Window Lock for Outward Sashes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Window/door locks for outward-opening sashes face challenges in flexible mounting and accessibility due to limited space and the need for non-protruding designs that allow for secure locking without obstructing the opening mechanism.
Innovation Solution
A window/door lock with two perpendicular mounting surfaces allows flexible positioning and alignment, enabling secure attachment to both the frame and sash, with a bolt mechanism for reliable locking and an actuating system accessible from either side, ensuring the lock can be used on both left- and right-opening sashes without obstructing the opening path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the base body is mounted on the frame with a single mounting surface, then the mounting position is fixed, but the flexibility to accommodate different sash configurations (left-opening vs. right-opening) is reduced
Solution Approach 1:
The base body is designed with two mounting surfaces that can serve different functions: one surface for mounting to the frame and another surface for mounting to the sash, allowing the lock to be configured for either left-opening or right-opening sashes using the same base body component
2Reliability
If the sash opens outwards, then the security against burglary is improved, but the available space for fastening the window/door lock on the inside is limited
Solution Approach 1:
The lock mechanism is designed to extend perpendicular to the sash surface, utilizing the third dimension (depth) rather than requiring additional surface area. The bolt projects from the base body in a direction perpendicular to the mounting surface, allowing secure locking without occupying valuable mounting space on the limited interior surface
3Ease of operation
If the actuating element is positioned for easy accessibility, then the ease of operation is improved, but the mounting position becomes constrained for different sash configurations
Solution Approach 1:
The actuating element is designed as a separate, movable component that can be positioned on different surfaces of the base body. The actuating element can be located on the first mounting surface, the second mounting surface, or on a side surface, allowing it to be positioned for easy accessibility regardless of whether the sash opens to the left or right

AI summary
A window/door lock for securing a window or door sash, particularly one opening outwards, in a closed position where the sash rests against the frame, comprises a base and a counterpart that can be optionally locked to the base. When the base is attached to the frame and the counterpart to the sash, locking the counterpart to the base secures the sash in the closed position. The base has two mounting surfaces, allowing it to be optionally attached to the frame using either of these surfaces. The two mounting surfaces are perpendicular to each other.
