Mounting Bracket for Roller Shutter Box Force Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional roller shutter box attachment methods fail to meet increased structural demands due to insufficient mechanical support, leading to overloading and potential masonry damage, especially with modern, thermally insulated materials that are not designed to handle increased wind loads and taller windows/doors.
Innovation Solution
A mounting bracket with a connecting web that spans at least 10 cm between a frame-side and wall-side connecting element, allowing direct force transfer from the frame to the lintel, thereby reducing the load on the roller shutter box and preventing thermal bridges, and can be adjusted to fit different roller shutter box heights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the roller shutter box is made of thermally insulated material with air pockets to improve thermal insulation, then thermal insulation performance is improved, but mechanical strength and ability to absorb wind loads deteriorates
Solution Approach 1:
The solution segments the force transmission path by introducing a separate mounting bracket structure that is mechanically coupled to both the frame and lintel, separating the thermal insulation function (roller shutter box) from the mechanical load-bearing function (mounting bracket). This allows each component to be optimized for its specific purpose without compromise.
Solution Approach 2:
The mounting bracket acts as an intermediary element between the frame and the lintel, providing a mechanical connection that transfers forces without requiring the roller shutter box to bear these loads. The bracket serves as a mediator that resolves the conflict between thermal insulation requirements and mechanical strength requirements.
2Stability of the object's composition
If the roller shutter box rests on side wall sections to provide structural support, then mechanical stability is improved, but thermal bridges are created and freedom of material choice is limited
Solution Approach 1:
The solution extracts the force transmission function from the roller shutter box by introducing a separate mounting bracket system. The bracket is mechanically coupled to the frame and lintel, extracting the load-bearing responsibility from the insulating box structure. This eliminates thermal bridges at the connection points while maintaining mechanical stability.
Solution Approach 2:
The mounting bracket serves as an intermediary that provides mechanical stability without creating thermal bridges. By being mechanically coupled to both the frame and lintel, it transfers forces while its insulating properties (or thermal break design) prevent thermal bridging between the frame and lintel through the roller shutter box connection points.
3Ease of operation
If conventional attachment methods are used to attach the frame to the roller shutter box, then ease of installation is maintained, but reliability under increased wind loads deteriorates
Solution Approach 1:
The solution segments the attachment system into two functional parts: the roller shutter box for thermal insulation and the mounting bracket for reliable mechanical attachment. The bracket is designed with specific connection elements that provide reliable attachment to both the frame and lintel, while the roller shutter box maintains its thermal insulation function without bearing wind loads.
Solution Approach 2:
The mounting bracket acts as an intermediary that provides reliable attachment under wind loads. It mechanically couples the frame to the lintel through the roller shutter box area, distributing and transmitting forces reliably. The bracket's design allows for easy installation while ensuring reliability under increased wind load conditions.

AI summary
The present invention relates to a fastening bracket (1) for creating a force-transmitting connection between a window or door frame and a lintel, and a corresponding roller shutter box (100) equipped with a fastening bracket (1).In order to enable an improved force-fit connection between a window or door frame and a lintel when roller shutter boxes are integrated below a lintel, without significant forces being introduced between the frame and the lintel via the heat-insulating material of the roller shutter box, of which the roller shutter box is predominantly made, it is proposed according to the invention that the mounting bracket (1) has a vertical connecting web (2) at one end of which a frame-side connection element (3) and at the other end of which a wall-side connection element (4) is arranged, wherein the height dimension between the frame-side connection element (3) and the wall-side connection element (4), measured between their opposite sides (5, 6), is at least 10 cm, preferably at least 15 cm and particularly preferably at least 20 cm.The corresponding roller shutter box (100) with a top (10a), a bottom (10b) that is at least partially open and an inside (10d) has such a mounting bracket (1).
