Abstract: A retractable suspension system adaptable for land, water, or amphibious vehicles substantially comprises: a bottom suspension arm having a wheel-axle assembly associated with its first end; a top suspension arm; spring means for interconnecting the arms; a horizontal suspension beam axle fixedly attached to the vehicle frame; and means attached to the vehicle frame and to the first end portion of the top suspension arm for adjusting the rotational orientation of the two arms about the suspension beam axle whose center is coincident with the second ends of the two arms. The suspension system can be partially retracted to accommodate for uneven load distributions on the vehicle and for levelling the vehicle on nonuniform terrain while it can be fully retracted for water use. Straight carry-through members which are extensions of the vehicle frame can be utilized to form the suspension beam axle.

Abstract: A modular planter panel system comprising a plurality of substantially identical modules forms decorative room dividers, partitions, or the like, by utilizing climbing plants such as ivy or vines. Each module substantially comprises: a frame; a planter box fixedly attached to the bottom portion of the frame and including the climbing plant; and relatively flexible means connecting associated portions of the frame for supporting the growing portions of the plant. Further means are included for supporting the module from the ceiling, from a horizontal overhead track, from a wall, or on the floor.
