Document Type and Number:
Japanese Patent JP3199821
Kind Code:
B2
Abstract:
PURPOSE: To make flat the floor surface by opening the lower frame.
CONSTITUTION: The lower frame of an opening frame of fittings is formed from a stationary lower frame 12 of a length corresponding to the door receptacle width of a sliding shutter B and a pair of vertical frames 10, 11 capable of rising and falling. The one vertical frame 10 is coupled with one-side vertical frame 3 while the other vertical frame 11 coupling with the stationary lower frame 12 using respective hinge metals 30 in such an arrangement that they can rise and fall. At the time of rising, these lower frames 10, 11 are held through a lower frame rise holding member 40 due to the receptacle seat of a metal piece 45 or a through hole 44 and a hook 41 relative to a runner frame member 20 of the sliding shutter B folded on the stationary lower frame 12 and one-side vertical frame 3 so that the floor surface G is opened flat. The lower frames 10, 11 are arranged in continuity with the stationary lower frame 12 so that the running guide 22 for the shutter B runs under guidance at the time of falling, and thereby the lower frame of the open frame of fittings is achieved.
