Abstract: A wheel mounting assembly for removably attaching a wheel assembly, typically comprising an axle and one or more wheels, to a platform attached to or integral with a wheeled object, such as skateboards, roller skates, rollerblades, backpacks, luggage, dollies and the like. The wheel mounting assembly comprises a wheel mount connector attached to the platform and a wheel mount, which is attached to the wheel assembly, that are configured for twist-and-lock engagement. The wheel mount has a mounting cavity for receiving the wheel mount connector and an internal elongated spring member that biases an engagement member into a slot on the wheel mount connector to prevent unintended disengagement of the wheel mounting assembly from the platform. One or more securing mechanisms secure the wheel mount to the wheel mount connector. The wheel mounting assembly can securely join multiple platform sections together without tools to simplify carrying or storing the object.
