Abstract: A backpack body has an openable accommodation chamber having a top opening. The accommodation chamber utilizes a restricting structure to position an energy absorption band. The energy absorption band includes a first layer and a second layer that are coincidingly bound. The top ends of the first and second layers extend first and second connecting portions respectively. The first and second connecting portions divergently protrude from the backpack body via the opening. The first connecting portion is configured for coupling with a safety harness, while the second connecting portion is for coupling with an anti-falling device. When the user falls, the falling makes the restricting structure release the first and second layers, so that the first and second layers leave the accommodation chamber via the opening for anti-falling suspension. Accordingly, the present invention has real improvements, including fine appearance, economic efficiency, and etc.
Abstract: The present invention utilizes a backpack body to define an openable accommodation chamber. The accommodation chamber further has an opening on the top end thereof for the communication of the inside and outside thereof. The accommodation chamber utilizes a restricting structure to position an energy absorption band. The energy absorption band is formed of at least a first layer and a second layer that are coincidingly bound. The top ends of the first layer and the second layer extend a first connecting portion and a second connecting portion respectively. The first connecting portion and the second connecting portion divergently protrude from the backpack body via the opening. The first connecting portion is for coupling with a safety harness, while the second connecting portion is for coupling with an anti-falling device.
Abstract: The present invention mainly aims to rebuilt the structures of a hook body, valve and control handle and the link relationship thereof. The outer surface of two shrouds of the control handle are respectively stamped with a depression adapted project a similar limit block out of the inner surface of each shroud, the limit block having upper, lower blocking surfaces opposite to each other vertically, and the upper, lower blocking surfaces are further controlled to be perpendicular to the shroud, thereby allowing them to transfer stably the stress between the hook body and valve when withstanding the stress due to the inadvertent opening of the valve so that the valve and limit blocks are not deformed easily, have a longer use and enhance the overall use safety greatly.

Abstract: A partitioned anti-falling connecting device includes a frame, a movable latch and a hoist ring. The frame has a hanging space with a gap defined between two ends thereof and at least a division island protrudingly arranged between the two ends thereof so as to divide the frame into at least a first section and a second section. The movable latch is arranged on the frame for opening and closing the gap.
