Mobile Device Clamp Assembly With Anti-Rotation Rail Interface

The clamp members feature asymmetric projections with specific geometric shapes (e.g., L-shaped, T-shaped, or rectangular profiles) that complement corresponding asymmetric openings in the rail. This asymmetric geometry creates a keyed interface that mechanically prevents rotation and lateral movement, transforming the symmetric cylindrical rail into a positionally constrained mounting point.

The projections extend in multiple dimensions from the clamp members, creating a three-dimensional engagement with the rail opening. This multi-dimensional constraint (preventing movement in X, Y, and rotational axes) elevates the mounting stability from simple radial clamping to comprehensive positional and orientational fixation.

The clamp assembly is divided into separable upper and lower clamp members that can be independently positioned and secured to the rail. Each clamp member can have its own projection, allowing the anti-rotation functionality to be distributed across multiple simple components rather than requiring a single complex integrated structure.

Instead of adding complex anti-rotation mechanisms to a simple clamp design, the invention inverts the approach by using the rail's existing opening geometry as the active constraint element. The projections are simple positive features on the clamps that passively engage with the pre-defined complementary openings in the rail, reversing the traditional approach of adding active constraints to the mounting device itself.
