Abstract

PURPOSE:To enable crew to easily and quickly move to an exit for refuge along a rope body in an emergency by providing the rope body extended and laid up to the exit upon occurrence of an emergency condition, and a means for extending the rope body in such a condition in a gravity-free space such as a space station. CONSTITUTION:A rope 1 is extended in slack state up to an exit 5 over the entire length of a pre-load section 4 at the corner of a space station, and retained with clips 3. The rope 1 is automatically tensioned by an extension device 2 installed at the opposite side of the exit 5, upon occurrence of an emergency. Also, the rope 1 is released from the clips 3 and retained under tension at the center of space in the station. According to the aforesaid construction, crew can move to the exist 5 by the help of the rope 1, and easily and quickly take refuge.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobility aid device applied to a zero gravity space such as a space station.

0002

[Prior Art] Conventionally, in weightless spaces such as space stations, handrails have been discontinuously installed around the periphery and corners of the weightless space as movement aids. It has become.

0003

[Problems to be Solved by the Invention] However, as mentioned above, conventional mobility aids are discontinuously installed around the periphery or corners of zero-gravity spaces, so in the event of an emergency, smoke is generated especially in the case of a fire, and visibility becomes difficult. If something goes bad, it will be difficult to evacuate quickly while holding on to it.

0004

[Means for Solving the Problems] The mobility aid device according to the present invention is aimed at solving the above problems, and includes a rope that extends in an emergency and is stretched toward an exit, and a rope that extends in an emergency. The invention is characterized by a configuration including a means for causing.

[0005]

[Operation] That is, in the mobility aid device according to the present invention,
In an emergency, the cable is extended and tensioned toward the exit, and the cable can be easily moved toward the exit along the extended and tensioned cable in an emergency.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIGS. 1 and 2 are structural explanatory diagrams of a mobility aid device according to an embodiment of the present invention. In the figure, the mobility aid device according to this embodiment is used in a zero gravity space station, and as shown in FIG. 4 up to the outlet 5 and held by a clip 3. When an emergency situation occurs, the rope 1 is automatically wound up by a stretching device 2 installed on the opposite side of the exit 5, leaves the clip 3, and is stretched and held in the center of the space. . Extension device 2
As shown in FIG. 2(b), a winding drum 2a is built in, and a drive device 2b rotates the winding drum 2a in response to a signal from a sensor to wind up the rope 1. rope 1
As shown in FIG. 2(a), convex portions are provided intermittently on the surface, the diameter of which increases in the direction approaching the outlet 5. 6
A handrail is provided on the surface of the experimental equipment 7, and is used for normal movement.

As described above, in this device, the rope 1 is held in the pressurized part 4 of the space station by the clip 3 with the rope 1 sagging in the corner of the floor so as not to interfere with the work during normal times, and when the pressure is reduced due to a collision with a meteorite etc. The rope 1 is automatically stretched and held by the tensioning device 2 by a pressure sensor, and also by a smoke sensor, temperature sensor, etc. in the event of a fire, so that in case of an emergency, the rope 1 is moved to the exit 5 along the rope 1. and can be easily evacuated. Also, rope 1
Since a convex portion is provided on the surface of the door 5 so that the direction of the exit 5 can be determined, the direction of the exit 5 can be easily known even when the fire is filled with smoke and visibility cannot be obtained. Furthermore, since the stretching device 2 is provided on the opposite side to the exit 5, the load on the stretching device 2 is reduced by obtaining the reaction force transmitted to the rope 1 from the side wall on the exit 5 side during movement.

[0008]

Effects of the Invention The movement assisting device according to the present invention is constructed as described above, and can be easily moved toward the exit along the cable in an emergency, thereby enabling quick evacuation.
