<p><P>PROBLEM TO BE SOLVED: To provide a resin sash which has different sectional forms with an upper frame, a lower frame and vertical frames, and also bonds the frames to perform framework. <P>SOLUTION: The upper frame 10 and the lower frame 11 are formed into the substantially same sectional form including a horizontal hollow part, and the right and left vertical frames 12 are formed into the substantially same sectional form including a vertical hollow part. The upper frame and/or the lower frame is different in aspect dimension. Horizontal frame wall parts 10b, 11b constituting the square of the horizontal hollow part and a vertical frame wall part 12b constituting the square of the vertical hollow part are formed into the substantially same shape except the aspect dimension, and the proportion of the aspect dimensions of the horizontal hollow parts 10a, 11a to the aspect dimensions of the upper frame 10 and the lower frame 11 is substantially equal to the proportion of the aspect dimension of the vertical hollow part 12a to the aspect dimension of the vertical frame 12. The upper frame 10, the lower frame 11 and the vertical frame 12 are cut at both ends like a slope, and the horizontal hollow parts 10a, 11a and the vertical hollow part 12a are abutted and bonded to each other to be continuous. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
