Aircraft mobile chock

DETAILED DESCRIPTION This invention presents an improvement with respect to the prior art and increased utility for potential users through provision of separable and separate mobile platform units that may be selectively applied to the ground contact elements of landing gear installations on an "as required" basis.
With such arrangement it is contemplated that for many uses only one or two mobile platform units may be required.
Such selective usage is facilitated by the various design configurations for the mobile platform units, the respective rolling support components, and the access ramps utilized.
For all embodiments of the invention, application of a mobile platform unit to the landing gear will serve to distribute the normally concentrated loadings of the tires and wheels to an increased ground contact area defined by the wheels, tires, rollers, or endless belts of the rolling support components used for the particular mobile unit.
In the preferred embodiment of the invention, the ramp or ramps which provide improved access to the platform additionally provide a braking action that operates to stop any movement of the rolling support components for the mobile unit.
For one nose wheel embodiment of the invention, the nose wheel extends through the platform and between separated rolling support components for the mobile unit for somewhat selective contact with the ground.
Where the ground support is adequate, the nose wheel will continue to provide at least a part of the support for the landing gear, and the nose wheel will be free to rotate and turn as required.
Under deteriorated ground support conditions the nose wheel will be locked to the platform, and all support will be provided by the rolling support components of the mobile unit.
