ABSTRACT:
A pneumatic device for holding an article in position in a container. The device includes an inflatable-deflatable mat adapted to be positioned in contact with a surface in the container. The mat generally conforms to the surface and defines an air passageway therethrough. The device also includes a plurality of expandable-contractable air chambers disposed about and in communication with the mat. The air chambers are inflatable and deflatable with the mat. The device further includes a pressure applying surface associated with the air chambers directly opposite the mat. The pressure applying surface is adapted to hold the article in position upon inflation of the mat and the air chambers. With this construction, the air chambers expand upon inflation to cause the pressure applying surface to engage and hold the article in the container under a substantially uniform pressure.
