Description

[Detailed description of the invention] This invention relates to an improvement of a vertical spiral rescue bag used when evacuating from a high place to the ground in the event of a fire or other disaster.

Although this type of vertical spiral rescue bag has existed in the past, there have been problems such as the descending space becoming partially narrow due to wind or the like, or the descending person turning over during the descent and falling head first.

Therefore, this idea was designed to keep the descent space at a constant opening, allowing for safe and smooth descent.

Hereinafter, the configuration of this invention will be explained according to the drawings shown as examples.

First, as shown in FIG. 1, this rescue bag 1 has a support frame 3 provided at the upper end opening of a cylindrical cover 2.
A rope 4 fixed to a portion of the cover 2 is suspended inside the cover 2 and extends to its lower end.

Further, inside the cover 2, a spiral bag 5 wound around the rope 4 in a spiral manner from its upper end to its lower end is arranged at an angle of about 40 degrees. The edge of the upper end opening 6 is fixed to the support frame 3.

As shown in FIG. 2, this spiral bag 5 has an internal descending space 7 opened in a substantially triangular shape, and the part of the spiral bag 5 that corresponds to the back 8 continuously faces the cover 2, and the back 8 are sewn to the cover 2 through the sewing thread 11 at two locations, upper and lower, as shown in FIG. It is sewn on 4.

In this way, by sewing the portion of the spiral bag 5 that corresponds to the back 8 to the cover 2 at two places, the descending space 7 can always be maintained at a constant opening, and the descending can be smoothly performed.

Furthermore, the cover 2 and the spiral bag 5 form an opening 10 at their lower ends, which is large enough for the descending person 9 to pull out.

When sewing the spiral bag 5 onto the rope 4, either use a sewing machine that removes tucks (creases wrinkles), or wraps the rope and wrinkles the fabric as shown in Figure 2. In this state, you can sew with a sewing machine.

When an escapee descends into the rescue bag with the above structure in the event of a disaster, the descending state is a spiral, and the effect of the wrinkles of the spiral bag 5 allows the descending speed to be maintained at an appropriate level, allowing the person to descend safely.
Furthermore, since the descending person passes through the spiral bag 5, his or her feet always face forward, so there is no risk of the person turning around and descending head first during the descent.

As mentioned above, this invention always maintains the descent space 7 at a constant opening, allowing safe and smooth descent for evacuation and escape, and has excellent practical effects.

Claims (1)

[Scope of utility model registration request] Inside the cylindrical cover 2, a rope 4 is arranged from the upper end to the lower end, and a spiral bag 5 is attached to the entire length of the rope 4 in a spiral shape. The cover 2 is sewn to the cover 2 at two places, upper and lower, at appropriate intervals over almost the entire length, and the contact part with the rope 4 is wrinkled and sewn to the rope 4, so that the descending space 7 inside the spiral bag 5 has a substantially triangular shape. A rescue bag characterized by being designed to open in a certain manner.
