Rotary Anchoring Element for Wall-Mounted Distribution Boxes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anchoring devices for meter and distribution boxes in double walls face challenges in efficient assembly and secure fastening, particularly due to the need for complex mechanisms and reliance on stop anvil designs which can be cumbersome and not universally adaptable.
Innovation Solution
A device featuring an elongate rotary element with a thread that engages an elastically expandable internal thread, allowing the anchoring element to be translated and then rotated for secure clamping, with a separate structural unit for the anchoring mechanism that includes a U-profile housing and a two-armed lever system, enabling easy assembly and stable anchoring without relying on a stop anvil.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a stop anvil design is used for anchoring the box, then the box can be positioned and anchored in the wall opening, but the stop becomes cumbersome and the design is not universally adaptable to different wall thicknesses
Solution Approach 1:
The anchoring element uses a lever arm with variable effective length that can be adjusted by rotating the lever around its pivot point. This allows the anchoring element to adapt to different wall thicknesses by changing the position where it contacts the rear surface of the wall, eliminating the need for a fixed stop anvil design
Solution Approach 2:
The anchoring element transitions from a static stop anvil design to a dynamic lever system that can rotate and adjust its position. The lever arm can be rotated to different angles to accommodate varying wall thicknesses, providing universal adaptability while reducing structural complexity
2Reliability
If a complex anchoring mechanism is used to ensure secure fastening, then the anchoring strength is improved, but the assembly process becomes less efficient and more difficult
Solution Approach 1:
The anchoring element is spring-loaded and automatically engages with the wall structure when the box is inserted. The spring force ensures reliable contact and anchoring without requiring complex adjustment mechanisms or multiple assembly steps, thereby maintaining high security while simplifying the assembly process
Solution Approach 2:
The anchoring element combines multiple functions into a single integrated component: positioning, anchoring, and adapting to different wall thicknesses are all achieved through one lever arm mechanism rather than requiring separate components for each function

AI summary
The invention relates to a device for anchoring an installation cabinet, in particular, a meter and/or distributor cabinet (1), in an opening (2) in a wall skin (3), wherein the cabinet (1) recessed in the opening makes contact with the front side of the wall skin (3) at the edge of the opening (2) with a stop (4), comprising an anchoring element (7), which may be moved into a position by a drive and clamping mechanism accessible from the front side of the cabinet (1), in which said element engages behind the wall skin (3) at the edge of the opening (2) and tensions the cabinet (1) between the stop (4) and the anchoring element (7). According to the invention, a counter holder (30) for the anchoring element (7) on the cabinet (1) is provided in a position remote from the stop (4).
