Burglar-Resistant Window Protective Strip Positive Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing burglar-resistant building closures face challenges in secure mounting of protective strips, which can be easily removed after damage to the outer frame profile, leading to compromised security and complex production processes, along with corrosion issues at connection points.
Innovation Solution
The protective strip is connected to a separate connecting element that is positively engaged with the frame piece before assembly, avoiding screws and thus preventing movement or removal, while being housed in a hollow profile for added security and protection from environmental influences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the protective strip is connected to the frame piece by means of a screw connection, then the burglary security is improved, but the production complexity and time increase
Solution Approach 1:
The connection system is divided into two separate components: a connecting element that is positively connected to the protective strip, and a coupling area in the frame piece. This segmentation allows the protective strip to be installed as a complete unit without requiring complex screw connections during production, while still providing secure anti-burglary protection.
Solution Approach 2:
The connecting element is pre-connected to the protective strip before the protective strip is installed into the frame piece. This preliminary action simplifies the production process by eliminating the need for complex screw connections during final assembly, while ensuring the protective strip remains securely attached to prevent burglary.
2Reliability
If the protective strip is connected to the frame piece by means of a screw connection, then the burglary security is improved, but the production time increases
Solution Approach 1:
The connecting element is pre-connected to the protective strip before installation into the frame piece. This preliminary action eliminates the need for time-consuming screw connections during final assembly, significantly reducing production time while maintaining secure anti-burglary protection.
Solution Approach 2:
The screw connection mechanism is replaced with a positive connection system consisting of a connecting element and coupling area. This substitution eliminates the need for threading and screwing operations, dramatically reducing production time while providing equivalent or superior burglary security.
3Strength
If the protective strip is made of hard metal, then the protection against bullets is improved, but the manufacturing complexity increases
Solution Approach 1:
The connection system is segmented into a connecting element and a coupling area, allowing the hard metal protective strip to be manufactured separately and then positively connected to the frame. This segmentation avoids the complexity of drilling and threading hard metal while maintaining bullet resistance.
4Shape
If the protective strip is housed in an outer frame profile, then the aesthetic appearance is improved, but the burglary security deteriorates
Solution Approach 1:
The protective strip with its connecting element is nested within the outer frame profile. This nesting arrangement maintains the aesthetic appearance by concealing the protective strip while the positive connection system ensures that the protective strip cannot be easily removed, thereby maintaining burglary security.

AI summary
The invention relates to a burglar-resistant building closure (101) for closing an opening in a building, comprising at least one frame composed of several frame legs and a filling (4) enclosed by the frame, wherein at least one frame leg is provided with a burglar-resistant protective strip (115) extending in its longitudinal direction made of a material resistant to abrasion, breakage and/or deformation.In order to further develop the building closure (101) in such a way that a better mounting option for the protective strip can be provided without restrictions on burglary protection, it is proposed that the protective strip (115) has a connecting element (116) which is positively connected to a coupling area (18) of the associated frame leg by the fact that, before the frame is assembled from the frame legs, the connecting element (116) of the protective strip (115) is inserted into the coupling area (18) from an end face of the associated frame leg in its longitudinal direction, whereby the positive connection thus achieved prevents movement of the protective strip (115) relative to the associated frame legs in a direction perpendicular to a plane defined by the infill.
