US Patent 9993931 Razor docking and pivot

A shaving razor system includes a razor handle that docks with a razor cartridge. The handle is configured to dock with the razor cartridge using a single hook configured to mate with a cartridge tab. A central pushrod is mounted with a spring into the handle, and is configured to exert a pushing force on the mounted cartridge. To eject the cartridge, the single hook may be pushed to pivot to the side of the cartridge tab, and thereby release the cartridge by ejecting it with a spring loaded pushrod.
