Free access floor and partitioning method

Abstract

A free access floor formed by free access panels arranged above a base floor. The free access floor includes a specific panel that is one of the free access panels and has a slit, and a partitioning plate inserted into the slit, so as to hang down from a surface of the specific panel and orient airflow in a space between the base floor and the free access panels.

What is claimed is: 
     
         1 . A free access floor formed by free access panels arranged above a base floor, comprising:
 a specific panel that is one of the free access panels and has a slit; and   a partitioning plate inserted into the slit, so as to hang down from a surface of the specific panel and to orient airflow in a space between the base floor and the free access panels.   
     
     
         2 . The free access floor according to  claim 1 , wherein
 the partitioning plate is provided between pillars that support the specific panel on the base floor.   
     
     
         3 . The free access floor according to  claim 1 , wherein
 the specific panel has an additional slit with the same shape as the slit.   
     
     
         4 . The free access floor according to  claim 1 , wherein
 the partitioning plate includes a flexible member and a weight attached to a lower edge of the flexible member.   
     
     
         5 . A partitioning method for partitioning a space between a base floor and a free access floor above the base floor, the free access floor being formed by free access panels, the method comprising:
 inserting a partitioning plate into a slit that is formed in a specific panel of the free access panels, so that the partitioning plate hangs down from a surface of the specific panel; and   orienting airflow in the space by the partitioning plate.
