Viewing Screen Mount With Pivoting Lock to Prevent Tilting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screen positioning systems face issues with tilting during rectilinear sliding displacement of securing bodies, requiring additional measures to prevent undesired tilting and complicating assembly and functionality.
Innovation Solution
A pivoting displacement mechanism is used instead of rectilinear sliding, with a securing body and screen body featuring circular peripheries for guiding cooperation, along with a spring member and blocking/slowing devices for secure and easy assembly and disassembly, utilizing a plastics product for the securing body produced by injection molding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If rectilinear sliding displacement of securing body is used, then secure attachment is achieved, but tilting occurs requiring additional prevention measures
Solution Approach 1:
The patent inverts the conventional rectilinear sliding displacement mechanism by implementing pivoting displacement instead. This inversion eliminates the inherent tilting problem associated with sliding mechanisms while maintaining secure attachment functionality through the circular guiding cooperation between the securing body and screen body.
Solution Approach 2:
The patent applies curvature by using circular periphery profiles for both the securing body and screen body. This spherical/curved geometry enables pivoting motion and guiding cooperation, replacing the linear sliding path with a rotational arc path that naturally prevents tilting while ensuring reliable engagement.
2Device complexity
If pivoting displacement is used instead of rectilinear sliding, then constructional simplicity is improved, but secure attachment reliability must be maintained
Solution Approach 1:
The circular periphery profiles of both the securing body and screen body create a self-guiding pivoting mechanism. This curved geometry simplifies the construction by eliminating complex linear guides and tilting prevention mechanisms, while the circular interaction ensures reliable attachment through consistent geometric engagement.
Solution Approach 2:
The pivoting mechanism with circular guiding profiles is self-regulating and self-guiding. The geometry itself prevents tilting and ensures proper alignment during assembly, eliminating the need for additional control elements or adjustment mechanisms, thereby simplifying construction while maintaining reliability.
3Ease of manufacture
If circular periphery profiles with guiding cooperation are used, then assembly simplicity is improved, but manufacturing precision requirements must be considered
Solution Approach 1:
The circular periphery profiles provide self-aligning guiding cooperation during assembly. This curved geometry tolerates certain manufacturing variations while ensuring proper engagement, as the circular interaction naturally guides the components into correct alignment, simplifying assembly without requiring extremely tight tolerances.

Function Achieved in This Case
This configuration simplifies construction and assembly, ensures reliable fastening, prevents tilting, and facilitates easy removal of the viewing screen while maintaining secure attachment, with the blocking and slowing devices enhancing usability and safety.
Implementation Method 1
a spring member (37) which is configured to, during pivoting of the securing body from the securing position to the free position, store a portion of the energy caused by the actuating force
Implementation Method 2
at least one part of the periphery of the protruding part of the securing body has a circular profile and adjoins at least one part of the periphery of the first recess in a guiding manner for guiding cooperation between the periphery of the protruding part and the recess during pivoting

AI summary
The invention provides a system for positioning a viewing screen. The system comprises a base body and at least one screen body. The screen body comprises a suspension hook and, on the one hand, is configured to be rigidly connected, at least in one position of the screen body, to the base body and, on the other hand, is configured to fasten a viewing screen thereto. The system further comprises a securing body for releasably securing the rigid connection between the base body and the screen body. The base body comprises a suspension edge. The suspension hook and the suspension edge are configured to suspend the screen body from the suspension edge of the base body via the suspension hook. Furthermore, the base body has a first hook edge and the securing body has a second hook edge, wherein the second hook edge is displaceable with respect to the screen body between a securing position in which the first hook edge and the second hook edge engage with each other, as a result of which or at least partly as a result of which the screen body is rigidly connected to the base body, and a free position in which the first hook edge and the second hook edge are free from each other to such an extent that the screen body is displaceable with respect to the base body. The system further comprises a spring member which is operative to withstand displacement of the second hook edge from the securing position to the free position, wherein the securing body is connected to the screen body so as to be pivotable about a pivot axis between the securing position and the free position.
