Title:
OPENING AND CLOSING STRUCTURE OF LIDS IN FIRE ESCAPE APPARATUS
Document Type and Number:
Japanese Patent JP3205810
Kind Code:
B2
Abstract:
PURPOSE: To make secure the opening and the closing of an upper lid and a lower lid pivotally installed in a housing frame housing a ladder while being installed on a slab, and to reduce the number of installing members of the opening and closing parts and to make their installing works easier.
CONSTITUTION: A bell crank 10 is pivoted to a housing frame 2. An upper link 11 is pivoted to the upper end of the bell crank 10 and an upper lid 3. A lower link 12 is pivoted to the lower end of the bell crank 10 and a lower lid 4. The pivot of the lower link 12 and the lower lid 4 is formed slidable along the longitudinal direction of the lower link 12. As a result, even though the lower lid 4 is rotated in the direction of closing at an opened time, the closing movement of the upper lid 3 can be prevented.
