Roof Window Support Elements for Gravity Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of skylights in roof openings is complicated by the increasing weight of larger and heavier roof windows, particularly with multiple glazing, which requires complex and costly lifting devices to avoid detachment and ensure safe insertion.
Innovation Solution
The skylight is designed with flexible carrying loops that attach to the vertical bars, positioning the center of gravity to match the roof inclination, allowing for direct insertion using a lifting device like a crane, with support elements that absorb the weight and remain attached to prevent detachment during installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the skylight size and glazing are increased to improve lighting and viewing, then the weight of the skylight increases, but this requires complex and costly lifting devices for safe installation
Solution Approach 1:
The patent applies preliminary action by pre-attaching support elements (carry straps or lifting eyes) to the skylight frame during manufacturing. These elements are positioned to align with the center of gravity, enabling the skylight to be directly lifted by a crane without requiring complex mounting devices. This preliminary preparation eliminates the need for complex installation equipment while supporting larger, heavier skylights.
2Ease of operation
If traditional mounting devices are used to handle heavy skylights, then the skylight can be lifted, but the mounting device must be removed before insertion into the roof opening
Solution Approach 1:
The invention extracts the lifting function from a separate complex mounting device and integrates it directly into the skylight structure through permanently attached support elements. The support elements are positioned so that when the skylight is suspended, its center of gravity aligns with the suspension point, enabling direct crane lifting without requiring attachment or removal of external mounting devices, thus eliminating time-consuming operations.
3Device complexity
If the skylight is designed with support elements attached between the vertical bars and installation brackets, then the installation is simplified, but the support elements must be positioned precisely to match the roof inclination
Solution Approach 1:
The patent applies local quality by providing adjustable support elements that can be positioned at different locations on the vertical bars. The support elements are attached at specific positions between the vertical bars and installation brackets, with their placement determining the suspension angle. This localized adjustability allows adaptation to different roof inclinations without requiring complex precision manufacturing, as the support elements can be repositioned to achieve the desired angle match.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design simplifies the installation process by aligning the skylight's inclination with the roof pitch, enabling easy insertion and reducing the need for additional tools or complex mounting devices, while ensuring the skylight's secure attachment and easy handling during installation.
Implementation Method 1
a distance of the carrying elements from an imaginary center of gravity plane receiving a center of gravity of the skylight and standing perpendicular to the vertical bars depending on a size of the skylight is selected in such a way that the skylight is present when suspended on the support elements due to the influence of gravity

AI summary
The invention relates to a roof window (1) for installation in a roof opening of a roof, with a frame (2) and a sash frame (3) which is pivotable with respect to the frame (2), wherein the frame (2) has two parallel vertical posts (8,9) and two horizontal posts (6,7) which connect the two vertical posts (8,9) and at least on the vertical posts (8,9) mounting brackets (5) for fastening the roof window (1) to a roof structure of the roof are attached.It is provided that a support element (20) of a pair of support elements is attached to each of the vertical beams (8, 9), in particular between each of the vertical beams (8, 9) and the corresponding installation bracket (5), wherein the distance of the support elements (20) from an imaginary center-of-gravity plane, which accommodates a center of gravity of the roof window (1) and is perpendicular to the vertical beams (8, 9), is selected depending on the size of the roof window (1) such that, when suspended from the support elements (20), the roof window (1) is at an angle of inclination due to the influence of gravity, which corresponds to at least one roof pitch angle. The invention further relates to a roof arrangement and a method for mounting a roof window (1).
