Document Type and Number:
WIPO Patent Application WO/2018/090158
Kind Code:
A1
Abstract:
Provided is an extending/retracting suspension apparatus which may be movably mounted on floor of building roof, comprising a load-carrying box (20) which may be moved and placed on the floor of a roof (10); the roof floor (10) has a parapet wall (11) formed thereon; a suspension arm (30) is formed by telescoping a plurality of extending/retracting frames (31, 32, 33); said plurality of frames (31, 32, 33) extend with each other, causing the suspension arm (30) to span at an incline between the load-carrying box (20) and the parapet wall (11), and causing the a triangular support frame to be constructed between the extended suspension arm (30), the roof floor (10), and the parapet wall (11); the plurality of frames (31, 32, 33) may be collapsed together to form a suspension arm (30) transport length; said suspension arm (30) transport length and the height of the load-carrying box (20) both are smaller than the height of an elevator room of the building; thus the invention solves the problems of conventional suspension apparatuses or structures being unfavorable to extension and retraction and of vehicular transport and elevator room transport being difficult.
