DUPLICATE FITTINGS

PURPOSE:To simplify the trouble for opening and shutting duplicate fittings and change the taste or function by forming an insert hole in the inner member of fittings at one-side frame of the body of fittings, another insert hole inside of another frame member of the body, and fitting the inner member on the intra-body side with possibility of replacement. CONSTITUTION:Sheet glasses 6 are fitted fast near insert pieces 21, 31 furnished on the upper frame 2 and lower frame 3 of the body 1 of fittings. Parallel with these sheet glasses 6, insert grooves 32, 52 for inner members of the fittings are formed inside of one vertical frame 5 and the upper and lower frames 2, 3 of the body 1, respectively. A slit-form insert hole 4H for the inner member of fittings is bored while the position mating with the insert grooves 32, 52, height, and width are made equal. In this insert hole H in the body 1. the inner member 7 fitted with sheet glass 8 is inserted inside of the frame material 171 with possibility of mounting and removal. This allows the opening/closing operation to take place with one side fitting member, and the taste and function can be changed only by replacing the inner member.
