Inspection Opening Closure Brackets for Secure, Easy Pivoting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for closing off openings, such as inspection openings in dry building structures, are not convenient to open and maintain while retaining simplicity and cost-effectiveness.
Innovation Solution
A device comprising two mutually interacting bracket devices, one immovably attached to the opening edge and the other pivotably articulated on a closure cover, with a pivot shaft facilitating easy installation and secure pivoting, using guide tracks with oblique profiles to prevent accidental opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a closure cover is pivotably articulated to an opening edge using simple attachment methods, then ease of operation is improved, but stability of the closure cover is worsened
Solution Approach 1:
The bracket device is divided into two separate bracket devices: a first bracket device immovably attached to the opening edge and a second bracket device attached to the closure cover. This segmentation allows the closure cover to pivot smoothly while maintaining stable connection points, resolving the contradiction between ease of operation and stability.
2Ease of operation
If a closure cover is made easily removable for full opening, then ease of operation is improved, but device complexity is worsened
Solution Approach 1:
The second bracket device acts as an intermediary component that facilitates easy removal and reattachment of the closure cover. By providing a standardized pivotable connection interface, it simplifies the removal process while the overall system remains relatively simple in design.
3Ease of manufacture
If guide tracks are oriented orthogonally to the opening, then ease of manufacture is improved, but reliability is worsened due to accidental slipping or sliding out
Solution Approach 1:
The guide tracks are deliberately designed with an oblique orientation relative to the opening plane, creating an asymmetric configuration. This oblique angle prevents the closure cover from accidentally slipping or sliding out while still allowing for relatively simple manufacturing and installation of the guide tracks.

AI summary
The invention relates to a device for closing off an opening, in particular an inspection opening, preferably in a dry building structure, in particular for a wall or a ceiling, in which the opening is formed in at least one panel-like structure element and can be closed off by means of a panel-like closure cover. For creating a device to be convenient to open and at the same time preferably retaining simplicity and cost-effectiveness, the device according to the invention comprises at least two mutually interacting bracket devices, of which a first bracket device is formed so as to be immovably attachable to an opening edge of the panel¬ like structure element, and a second bracket device is formed so as to be attachable to the closure cover and can be pivotably articulated on the first bracket device.
