Abstract

A tall building escape apparatus includes two upright sliding rails on one side of a building where two escape exits are located. The sliding rails are cylindrical rods extended from the ground floor to the top floor of the building corresponding to hanging racks located on the top floor. The hanging racks have pulleys mounted thereon to wind a rope between the two hanging racks. The rope has two ends fastened respectively to an escape case. The escape case has retaining rollers with curved periphery to clamp the sliding rails, buffer members on the bottom side, and an entrance / exit opening on one side directing to the escape exit. When a user escapes by descending through one escape case, another escape case is pulled by the rope upwards to enable another user to escape. Thus escape speed is faster, and safety is enhanced and there is no limitation of the applicable height.

Description

FIELD OF THE INVENTION

[0001] The present invention relates to a tall building escape apparatus and particularly to an escape apparatus to provide rapid escape without using power equipment. BACKGROUND OF THE INVENTION

[0002] Public building has to provide fire fighting and escape facilities. The most commonly used escape facility is the slow descending apparatus which includes a hanging rack fixedly installed on each floor of the building and a slow descending device located nearby. In the event of fire breaking, the slow descending device is hung on the hanging rack, and a loop strap of the slow descending, device is hitched on the user. The user may descend slowly to the ground floor by means of user's own weight from the high rise building.

[0003] However such a slow descending apparatus has drawbacks, such as the escape speed is slow, poor safety, and has limitation on the applicable height. Details of these drawbacks are elaborated as follow:

[0004] 1. Slow escape speed: [0005...
