Transverse Window Safety Lock with Anchored Telescopic Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing safety devices for securing windows or doors against forced opening often require complex and costly telescopic mechanisms, can damage the frame or sash, and are not easily removable or user-friendly, leading to inconsistent use due to cumbersome installation and operation.
Innovation Solution
A safety device featuring a locking bar anchored transversely in front of the sash, with a permanently mounted anchoring element in the reveal that interacts with a coupling section and locking device, allowing for stable and easy installation without direct interaction with the masonry, and providing a simple, reliable, and adjustable locking mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a telescopic locking bar mechanism is used to engage in opposite reveal holes, then the locking bar can be positioned between the reveal, but the mechanism becomes mechanically less stable and technically complex with higher costs
Solution Approach 1:
The invention extracts the telescopic mechanism from the locking bar itself and relocates it to the anchoring elements. The locking bar becomes a simple rigid component, while the anchoring elements contain the telescopic adjustment capability, allowing the locking bar length to be adapted without compromising its structural stability.
Solution Approach 2:
The anchoring elements serve as intermediaries between the rigid locking bar and the reveal holes. These anchoring elements incorporate the telescopic mechanism, enabling length adjustment while maintaining the simplicity and stability of the locking bar itself. The coupling section of the anchoring element mediates the connection between the reveal and the locking bar.
2Reliability
If safety devices are mounted on the frame and wing, then additional connection points are provided for security, but damage occurs to the frame and sash
Solution Approach 1:
The invention extracts the mounting function from the vulnerable frame and sash components and relocates it to the reveal area. By positioning anchoring elements in the reveal rather than on the frame or sash, the security device provides additional connection points without causing damage to the window or door structure.
Solution Approach 2:
The anchoring elements are designed as separate, replaceable components that can be installed in the reveal without permanently modifying the frame or sash. This allows for easy removal and replacement if needed, protecting the main structural components from damage.
3Reliability
If holes are precisely aligned in the reveal for locking bar insertion, then the locking bar can be anchored, but the installation becomes complex and time-consuming
Solution Approach 1:
The anchoring elements are pre-assembled with their coupling sections before installation. This preliminary preparation allows for easier alignment and installation, as the complex telescopic mechanism is already configured in the anchoring element rather than requiring precise alignment of multiple components during installation.
Solution Approach 2:
The coupling section of the anchoring element serves as an intermediary that simplifies the connection process. It provides a standardized interface between the locking bar and the reveal, reducing the precision requirements for hole alignment and simplifying the overall installation procedure.

AI summary
A locking device with a locking bar, which can be positioned transversely in front of the closed sash of a window or door as needed to secure the sash against opening, comprises at least one anchoring element. The anchoring element is designed to be permanently mounted on one side of the window or door in the area of a reveal of the window or door and has a coupling section that, when the anchoring element is mounted, projects towards the opposite side of the window or door. The locking bar has a locking device and at least one first end section with a coupling receptacle, which is designed to be detachably coupled to the anchoring element by the coupling section of the anchoring element engaging in the coupling receptacle of the first end section of the locking bar when the locking device is coupled.Furthermore, in the coupled state, the first end section of the locking rod can be locked to the anchoring element by means of the locking device.
