Description

This invention relates to a device for preventing people from falling into a reservoir, and in particular to a device for preventing people from falling into a reservoir, etc.

A conventional rescue device for people who fall into reservoirs, etc., is disclosed, for example, in JP 2020-50076 A. According to JP 2020-50076 A, the rescue device for people who fall into reservoirs, etc., uses a rectangular floating frame to hold a rectangular net afloat on the water surface. The floating frame is made of polyethylene foam, and the net is made of polyester. The net is a hexagonal mesh made of polyester wire twisted into three threads, and is attached so that the twist is parallel to the short side of the frame. The net is extended to the boundary between the land and the water surface, and a rope is configured to tie the net to the bank. As a result, people who have fallen off the bank slope can be rescued, and installation and removal can be easily performed.

JP 2020-50076 A (Abstract, etc.)

Conventional rescue devices for people who fall into reservoirs and other structures are constructed as described above. Such devices are large in scale and can be difficult to install in small reservoirs. In addition, the netting material must be secured to the bank with three ropes, anchors, and U-shaped anchor pins, making it difficult to respond in an emergency.

This invention was made to solve the above problems, and aims to provide a compact device to prevent people from falling into a small reservoir that can be easily installed even in small reservoirs.

The reservoir slip prevention device of this invention includes a rope with a hook at the end, multiple gripping parts attached continuously to the rope, a float attached continuously to the multiple gripping parts, and a weight attached continuously to the float.

Preferably, the plurality of gripping portions includes a ladder.

More preferably, the ladder includes multiple steps made of pipes having a predetermined width, and a connecting member made of rope that connects the multiple steps.

The ladder may be fitted with a float and a weight.

The pipe may be made of aluminium.

According to one embodiment of the present invention, the multiple gripping portions include multiple loop-shaped ropes that are separated from one another.

It is preferable that the rope is provided with a bell.

According to this invention, the reservoir slide prevention device includes a rope with a hook at the end, multiple gripping parts connected to the rope, a float connected to the multiple gripping parts, and a weight connected to the float, so that it can be easily installed even in small reservoirs and is compact, making it possible to provide a reservoir slide prevention device.

1 is a perspective view showing a reservoir slide prevention device according to one embodiment of the present invention. FIG. 2 is a plan view showing the reservoir slide prevention device shown in FIG. 1. FIG. 13 is a diagram showing a reservoir slide prevention device according to another embodiment of the present invention.

An embodiment of the present invention will now be described with reference to the drawings. Fig. 1 is a perspective view showing a reservoir slide prevention device 10 according to an embodiment of the present invention. Referring to Fig. 1, the reservoir slide prevention device 10 includes a rope 12 having a hook 11 at the end, a bell 13 attached to the rope 12, a ladder 14 connected to the bell 13, a float 20 connected to the lower part of the ladder 14, and a ring-shaped weight 21 attached to the lower end of the float 20. The float 20 and weight 21 at the lower part of the ladder 14 are also connected by a rope 19.

Figure 2 is a plan view of the reservoir slide prevention device 10 shown in Figure 1. The specific configuration of the ladder 14 will be described with reference to Figure 2. The ladder 14 is configured such that one rope 12 is divided into two, and the two divided ropes 14a, 14b support the ladder step 15 on both sides. The step 15 is tubular and made of, for example, aluminum.

As shown in the diagram, there are holes near both ends of the pipe, and a rope is passed through the holes and the bottom of the pipe is supported by tying a knot in the rope to position the pipe so that it does not fall to the ground. The pipe is also shaped like a ladder, so a person who falls can grab the rope at a place above the water's surface where they can breathe, and wait with both feet on the pipe. This allows the person who finds them to pull the person who has fallen down and rescue them.

Also, because of this shape, children or people who have difficulty standing on their own can wait by putting both feet through the pipes and sitting on their buttocks, as if they were sitting on a swing.

Even if you don't have grip strength, you can wait using a pipe or your elbow to support your body.

As described above, the pond slip prevention device 10 according to this embodiment has a ladder 14 attached as a slip prevention device to a rope 12 having a hook 11 at the end. This allows the ladder 14 to be attached to a tree, fence, etc. near the pond using the hook 11. This eliminates the need to separately prepare anchors, etc., as in the past, and does not take much time to install. In addition, because the configuration is simple, it can be installed in any pond.

In addition, the pond slide prevention device is equipped with a bell, so even if a person who has fallen into the pond is unable to speak, their location can be identified by the sound of the bell. The location can also be identified at night.

Also, if someone falls into the reservoir, they can hold on to the ladder 14 and wait for rescue, and if necessary, they can grab the rope 12 and climb up. The ladder 14 also functions as a foothold.

Furthermore, when the water level is low, the person can climb up along the rope 12, and when the water level is high, the person can hold on to the ladder and maintain their body position without sinking below the water level.

Next, another embodiment of the present invention will be described. Figure 3 is a diagram showing a reservoir slide prevention device 30 according to another embodiment of the present invention. Referring to Figure 3, in this embodiment, the reservoir slide prevention device 30 includes a rope 32 having a hook 31 at the end, and a plurality of gripping parts attached to the rope 32, similar to the previous embodiment. Here, the plurality of gripping parts include a plurality of loop-shaped ropes 33, 34.

The multiple ring-shaped ropes 33, 34 are provided separately from each other, and each ring-shaped rope 33, 34 is independently attached to the rope 32, for example, at intervals of 30 cm. The size of the ring is large enough to fit a leg or arm inside.

Although not shown here, the float 20 and the ring-shaped weight 21 attached to the lower end of the float 20 are attached to the lower part of the multiple ring-shaped ropes 33, 34.

In this embodiment, as in the previous embodiment, a bell may also be provided.

Although an embodiment of the present invention has been described above with reference to the drawings, the present invention is not limited to the illustrated embodiment. Various modifications and variations can be made to the illustrated embodiment within the same scope as the present invention or within an equivalent scope.

The reservoir slide prevention device of this invention can be easily installed and is therefore advantageously used as a reservoir slide prevention device.
