US Patent 11825918 Magnetic coupling device with mechanical interlock features

A coupling device for releasably coupling two parts with one another includes first and second coupling members having magnets for holding the members with a magnetic holding force to self-center the members in an intermediate position. The coupling members are slidable to a locked condition in which mutual interlock portions engage and slidable to an unlocked position in which mutual unlock portions engage. The coupling members are uncoupled by sliding the members along a first unlocking path to the unlocked position and further moving the members along a directionally different separation path.
