STRUCTURE FOR COMBINING OF PLURAL RESPECTIVE OBJECTS HAVING PLANE

摘要

PURPOSE: A coupling structure of plural objects having a plane is provided to change relative position of plural independent objects by forming each zipper rail units in the same direction. CONSTITUTION: A coupling structure of plural objects having a plane comprises a first zipper rail unit, a second zipper rail unit, a third zipper rail unit, and a fourth zipper rail unit. The first zipper rail unit is formed in the planar section of a first object. In the first zipper rail unit, a plurality of zipper rails are arranged in parallel with each other. The second zipper rail unit is formed in the planar section of a second object. The third zipper rail unit is formed in a flat part of a middle object. The fourth zipper rail unit is formed in the opposite side planar section of the middle object.
