ABSTRACT:
A life-saying travel bag includes a suitably long, wide and durable rope sewn with a zipper on each side such that the rope forms a substantially cylindrical bag when the side zippers are closed. A fastening mechanism is disposed near either end on the inside of the bag, and a fastening strap is arranged at either end of the bag for connecting to a shoulder strap for carrying. An upper cover and a lower cover are respectively connected to the ends of the bag by zippers. The upper cover accommodates a speed control means which has a narrow recess at its center for containing an adjusting rod with an eccentric shaft. The ends of the shaft are connected to a control lever which may bring the adjusting rod to rotate towards or away from the opening of the recess so that the rod may be retained at or disengage from the opening to achieve the object of control. The zippers may be opened so that the rope is extended to its full length. One end of the rope may be tied to a secure structure of the building while the user is firmly suspended on the rope by means of the shoulder strap and fastening mechanism. The user may manipulate the control lever to drop at a safe speed to the ground.
