Built-in Element Wall Connection Anti-Lever Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing built-in elements for separating interior and exterior spaces, such as doors and windows, lack effective burglary protection, as they can be easily levered out by burglars due to their design, allowing unauthorized access.
Innovation Solution
The wall connection is designed with a blocking area that protrudes into a recess after a side part is bent over, engaging in a form-fitting manner to prevent removal, enhancing burglary protection by ensuring the blocking area is present at least after the side part is bent, thereby preventing the fixed element from being levered out.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the wall connection is designed as a simple U-profile for easy installation, then the ease of operation is improved, but the burglary protection is worsened as burglars can bend the side panel and lever out the fixed element
Solution Approach 1:
The blocking area is pre-formed in the wall connection at a position that is not yet active during normal operation. When a burglar bends the side panel, the blocking area is preliminarily positioned to engage with the recess in the end area, preventing lever-out actions. This preliminary structural arrangement activates the anti-burglary function exactly when needed, without complicating the initial installation process.
2Reliability
If the wall connection includes a blocking area that engages with the end area to prevent lever-out actions, then the burglary protection is improved, but the device complexity is worsened
Solution Approach 1:
The blocking area is merged with the wall connection structure itself rather than being a separate component. The wall connection integrates both the mounting function (fastening to the wall) and the anti-burglary function (blocking area engaging with the recess) into a single structural element. This merging approach provides enhanced burglary protection without significantly increasing device complexity, as the blocking feature is formed as part of the wall connection's basic geometry.

AI summary
The invention relates to a built-in element (30) for separating an interior space (51) from an exterior space (52), comprising a fixed element (20) having an end section (21) and a wall connection (10) for attaching the fixed element (20) to a wall (50), wherein the wall connection (10) has side parts (12) for receiving the end section (21) and at least one wall part (11) for attaching the wall connection (10) to the wall (50). According to the invention, the wall connection (10) is designed such that, after a side part (12) is bent over, the wall connection (10) has a locking area (14) that can project into a recess (22) of the end section (21).
