摘要

PROBLEM TO BE SOLVED: To enable one worker to assemble a door frame efficiently by himself without impairing finish precision.;SOLUTION: This door frame is constituted by forming protruding pieces 15, 16, 24, 25 in end parts in the direction of length of the horizontal frame members 1, 2, forming insertion grooves 35, 36, 37, 38, 45, 46, 47, 48 in which the protruding pieces are inserted in the vertical frame members 3, 4, and forming a fitting groove S extended in the direction of groove width of the insertion grooves on terminal sides of the protruding pieces 15, 16, 24, 25. End fringes in the direction of groove width of the insertion grooves 35, 36, 37, 38, 45, 46, 47, 48 form a part to be fitted in which the fitting groove S is fitted. The protruding pieces inserted into the insertion grooves move in the direction of groove width of the insertion groove to fit the end fringes in the direction of groove width of the insertion grooves in the frame member on one side into the fitting groove of the protruding pieces of the frame member on the other side.;COPYRIGHT: (C)2009,JPO&INPIT
