ELASTIC INTERIOR MATERIAL FOR AGGREGATE FORM AND STRIP FORM (SHORT WIDTH) TYPE REGULATED FLOOR HAVING CONTINUOUSLY SHAPED FEATURE OF THE SAME ALTERNATELY AND REVERSELY INCLINED PROTRUSION AND RECESSION IN THE JOINT FACE IN SPITE OF THE CROSSING DIRECTION SO THAT THE JOINT ON THE FRONT SIDE EXTENDS LINEARLY

摘要

PURPOSE: To bring no level differences even when the upper side undergoes a heavy weight and retain the junction, by making a basic three-dimensional constitution line positioned in the fingers' shape and constituting joint faces in such an arrangement that the fingers' shapes are connected to each other at both ends. ;CONSTITUTION: A basic three-dimensional constitution line 1 is made, in which the front face side is positioned as the palm of the hand, the rear face side is positioned as the back thereof, the protruding joint face is positioned as the fingers, the recessed joint face is positioned as valleys, and the rugged parts are positioned as joints of finger bones. The joint faces are constituted in such an arrangement that both end of respective fingers are connected to each other and arranged so as to joint the right hand to the left hand. As a result, the joint at the front face side becomes linear and we can get the continuously shaped joint face of the same alternately and reversely inclined protrusions and recessions in spite of the right-angled crossing direction against the joint. And even if the weight of persons, furniture, etc., acts on the joints from the upper side, it does not cause level differences and retains the junction.;COPYRIGHT: (C)1996,JPO
