Wall Anchor Hook Structure for Tool-Free Profile Rail Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wall anchor systems for mounting sanitary fittings are complex and require multiple elements and tools for fixation, making them difficult to install.
Innovation Solution
A wall anchor design featuring an anchor plate with a threaded fixing portion and two hooks that can be easily connected to a profile rail without tools, using a pivot movement to engage with protrusions, providing a secure and tool-free attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional anchor bolts and multiple elements are used for fixing, then the connection strength is sufficient, but the mounting complexity increases and tool requirement arises
Solution Approach 1:
The invention combines multiple functions into a single integrated wall anchor component. The anchor plate integrates the threaded fixing portion for anchor bolt reception and two hooks for profile rail engagement, eliminating the need for separate elements like nuts, washers, and additional fasteners mentioned in the prior art.
Solution Approach 2:
The wall anchor is designed with multi-functionality to perform both anchor bolt fixation and profile rail engagement through its dual-hook mechanism. This allows a single component to serve multiple purposes: providing threaded engagement for the anchor bolt while simultaneously offering hook-based connection to the profile rail protrusions.
2Ease of operation
If traditional screw connections are used, then the connection is secure, but the tightening process requires tools and increases mounting time
Solution Approach 1:
The hook mechanism is designed to self-engagement with the profile rail protrusions. The hooks are configured to automatically grip onto the protrusions when the wall anchor is positioned, eliminating the need for external tools to tighten or secure the connection. The geometric configuration of the hooks and protrusions creates a self-locking effect.
Solution Approach 2:
The hooks feature curved geometries with undercuts that complement the shape of the profile rail protrusions. This curved design allows the hooks to naturally conform to and grip the protrusions, creating a secure connection through geometric interlocking rather than mechanical fastening.
3Stability of the object's composition
If the hooks are designed for firm engagement, then the connection stability improves, but the installation flexibility may be reduced
Solution Approach 1:
The wall anchor design allows for dynamic adjustment during installation. The hooks can accommodate slight variations in positioning as they engage with the protrusions, and the anchor plate can be adjusted before final engagement. Once installed, the connection becomes stable and fixed, providing both installation flexibility and operational stability.
Solution Approach 2:
The two hooks are arranged asymmetrically on the anchor plate, with different orientations and positions. This asymmetric configuration allows the wall anchor to engage with the profile rail in a specific orientation while maintaining flexibility in the engagement process. The asymmetric design ensures proper alignment and stable connection once engaged.

AI summary
A wall anchor (1), having an anchor plate (2) with a front face (3) and a rear face (4), a fixing portion (5) which protrudes from the front face (4) of the anchor plate (2), which extends along a centre axis (M) and has a threaded structure (6) for receiving an anchor bolt (7), and two hooks (8, 9) which protrude from the rear face (4) of the anchor plate (2). The hooks (8, 9) are configured such that the wall anchor (1) can be fixedly connected to a profile rail (18) by protrusions (21) of a profile rail (18), with respect to forces acting in the direction of the centre axis (M).
