Automated storage and retrieval system with retractable mountings

The invention is an automated storage and retrieval system. Positionable objects are stored in columns within a frame. When a user requests an object, the objects are selectively relocated until the requested object is brought to an access point. The objects are relocated by planar motion mechanisms attached to the walls of the frame. When not moving, the objects are suspended from mountings that extend from the same walls that the planar motion mechanisms are attached to. The mountings are controlled by actuators within the walls. The mountings are retractable to allow the planar motion mechanisms to pass. Each of the objects is supported by more than one mounting so that support is not withdrawn when any one mounting is retracted to allow a planar motion mechanism to pass. The design allows objects to be arranged in more than two columns within an automated storage and retrieval system.
