Description

[Detailed description of the invention] This invention relates to an inflatable slide for quickly and safely evacuating passengers to a lifebuoy or to the ground in an emergency.

Hereinafter, an inflatable slide for ships will be explained as an example.

Conventional inflatable slides for ships are shown in Figures 1 to 4.
As shown in the figure, a slide main body 1 consists of a main air chamber 5 that provides rigidity, an upper air chamber 6 that serves as a side guide when sliding down, and a sliding cloth 7 on which a victim 9 slides.
It consists of a float 2 that floats on the sea surface and is used to transfer to a raft.

As shown in FIG. 4, the sliding cloth 7 is fixed to the left and right upper air chambers 5 by gluing both ends thereof with adhesive portions 12 so that the sliding cloth 7 is stretched horizontally.

The inflatable slide is degassed, stored in a container, etc., and set on the third side of the ship's side.In an emergency, it is dropped into the sea and expanded with gas, and the slide body 1 and float 2 are
The ship retains its shape, slides down the sliding cloth 7, and allows the victim 9 to leave the ship.

As described above, the conventional sliding cloth 7 is stretched horizontally between the left and right main air chambers 5, and is also left slightly slack, on which the skier 9 slides. In Fig. 2, there is almost no acceleration at the beginning of the slide at point A, but as it reaches point B, the acceleration increases, and at point C, which is the float boarding part 8, it accelerates to a considerable speed, causing fear in the skier 9. In addition, when getting on the float 2, you may hit your foot strongly against the float floor 10 and trip, or you may fall, or the tip of the float D may be too strong.
There is a drawback that it jumps out.

This invention was made in order to eliminate the drawbacks of the conventional ones as described above, and the sliding cloth 7 having a constant width l is made to have one or more slacks 14 in the sliding direction of the sliding cloth depending on the length of the slide main body 1. The purpose is to provide a slide main body 1 with which a slider 9 can safely slide down by providing an anti-slip part to prevent acceleration over the entire length of the slide main body 1.

Examples of this invention will be described below with reference to FIGS. 5 to 7.

In FIG. 5, a sliding cloth 7 having a constant width l is placed to create slacks 14 at three locations with a depth of 0.2 m to 0.5 m in the sliding direction of the cloth. Each slack part has a slack 14 in the sliding direction and a non-slip part 15, and the slack part is used to attach the sliding cloth 7 of a constant width l to the left and right cylindrical main air chambers 5, as shown in FIG. Sag depth is 0.2m
The adhesive part 12 is provided at the _H1 position so that the distance is ~0.5m, the slack is gradually removed from the slack 14, and the slip cloth 7 is attached to the anti-slip part 15 as shown in FIG.
The adhesive part 12 is provided at the _H2 position where there is almost no slack.

When the slider 9 slides down the sliding cloth of the slide main body 1 from point A, it is gradually accelerated and the slack part 14
It skies down to point B. The slack in the width direction of the sliding cloth at the slack portion 14 becomes narrower as it approaches the slack portion 14 in the sliding direction because the bonded portions of the sliding cloth face toward the cylindrical center of the main air chamber 5 (W ₁ decreases). This increases the contact area of the downhill person 9 and reduces the speed. As the skier passes point B and continues downhill, the sliding cloth 7 is provided in a direction that reduces sagging, so the slope of the slide becomes gentler, gradually decreasing the speed of the skier 9, and eventually the slippery part 1
5, the descending speed is minimized, and the descending speed increases toward the next slack section 14.

The above steps are repeated three times in Figure 5, and the acceleration that occurs over the entire length of the slide body 1 can be eliminated.
To enable safe transfer to a float floor 10.

As described above, according to this invention, the sliding cloth 7
By providing one or more slack parts 14 in the sliding direction, the acceleration generated when the slider 9 slides down the entire length of the slide body 1 is suppressed, and it is possible to safely transfer to the float floor.

Furthermore, by using the sliding cloth 7 having a constant width, the sliding cloth 7 can be processed easily and economically.

Claims (1)

[Scope of utility model registration request] An inflatable slide comprising left and right main air chambers each having a cylindrical cross section and a sliding cloth formed with the same width dimension in the length direction and having both sides joined to opposing peripheral walls of the main air chamber, A sagging portion is formed in the sliding cloth by gradually and periodically changing the joining position of both sides of the sliding cloth to the peripheral wall of each main air chamber in the circumferential direction over the length thereof to make the whole wavy.
