<P>PROBLEM TO BE SOLVED: To provide doors and/or windows capable of easily corresponding to widely diversified product variation and also of considerably reducing their production costs. <P>SOLUTION: A coupler 225 with two inner and outer points is formed at an outer bottom rail 22A thereby coupling an inner bottom rail 22B to either of the two inner and outer points thereby permitting to form a bottom rail 22C having a different depth. Therefore, it becomes possible to form a double sliding window 1A with sashes 20C having different depths by making the outer bottom rail 22A in common with the inner bottom rail 22B thereby decreasing a period of time schedule from design to production and reducing the production costs and parts control costs. <P>COPYRIGHT: (C)2008,JPO&INPIT |
