Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an inflatable buoy which is always mounted on a ship, and when the device is submerged in water, the storage box is automatically opened to release a floating body from the inside. And a tightening device for the storage box.

[0002]

2. Description of the Related Art As a life-saving device for small boats such as yachts and pleasure boats, small fishing boats, etc., a rectangular or circular gas inflatable floating body having a gripping rope attached to the outer periphery is folded to a small size. Store it in a storage bag and store it in a prescribed place in the cabin, and in an emergency, remove it from the storage bag, manually inflate it and drop it on the sea, and the victim will grab it and wait for rescue. There is a so-called inflatable float used.

[0003]

This conventional inflatable float has the following defects, and it is desired to solve these problems. That is, this type of inflatable life preserver can be folded and stored at any time, so that it is small and lightweight as a whole. For this reason, it is suitable for equipping small ships sailing in the coastal waters and coastal waters, but if it is easily placed on the deck, it may be blown by the wind or touched by the waves. In order to prevent this, in reality, this type of life preserver is stored in a storage box in the cabin.

If stored in such a state, in case of emergency, the crew must take it out from the cabin, take it out of the storage bag, and then manually inflate it to bring it out onto the water. It takes time. In order to prevent this, a conventional inflatable buoy can be placed in a container and firmly fixed to, for example, the mast of a ship, but in case of an emergency such as overturning at an instant, which is often the case in small boats. It can be said that the work of opening the lid from the container, taking out the floater, manually inflating it, and taking it out to the sea is completely impossible. As described above, the conventional inflatable buoy has problems both in mounting on a small boat and in inflating mechanism.

[0005]

In order to solve the above problems, the inflatable buoy according to the present invention comprises a container and a lid, which is a storage box for accommodating a floating body which is inflated to form a lifesaving buoy. Then, the container and the lid are kept in a tightly closed state with honey by a rope stretched by a biased spring, and the rope is cut by a cutter that operates in response to water. The conventional problem is solved by releasing the tightened state and automatically operating the gas charging device attached to the floating body to expand the floating body to form a floater. It is a thing.

Further, in the tightening device for the storage box, a rope is stretched by the tightening spring between a spring housing cylinder having a tightening spring therein and a water responsive device which operates in response to water.
Tighten the storage box consisting of the container and the lid with the tension of the rope,
It is preferable that the operation of the water response device cuts the rope to open the storage box.

Both the container and the lid are provided with push-opening springs acting in opposite directions, which are opposite to each other, or the container of the storage box is made smaller than the size when the floating body is folded. It is preferable that the container is opened when the rope is cut by forcing the floating body into the storage box.

As the rope, it is preferable to use one having excellent water resistance and durability, such as nylon or vinylon, and one that can be cut completely with one blade with a sharp blade.

Since a part of the rope is exposed, in order to prevent water from penetrating into the water-responsive cutting device from here, plastic or rubber is applied to the rope passing through the water-responsive cutting device. Such a stretchable tube is covered, and both ends thereof are folded back at both outlets of the water-responsive cutting device to block the insertion hole of the rope from the inside of the water-responsive cutting device.

The rope is stretched to some extent when a tensile force is applied due to its attributes. Therefore, the rope is always stretched in a tensioned state in anticipation of the elongation of the rope.

The rope has a predetermined length and is connected to the spring accommodating cylinder and the water-operated cutting device in advance. Both ends of the rope are tightly bound by closing pipe fittings. It is attached to the storage box while compressing the spring. On the contrary, it can be removed from the storage box.

Both ends of the rope are preferably extended further without cutting near the closure to allow the containment box to be tied to the mast of the ship, for example.

The storage box is provided with a portion for accommodating the water-responsive cutting device, while the spring accommodating cylinder can be quickly grasped by the hand.

[0014]

In the inflatable float of the present invention, the floating body that expands to form a life-saving float is always housed in a storage box. The storage box is composed of a container and a lid. And are tightened by a rope which is tensioned by a tightening spring urged to maintain the closed state in a watertight manner.

When water enters the inside of the water-responsive cutting device, the engagement that had been balanced with the force of the actuating spring is released instantly, and the cutter is moved by the force of the actuating spring to move the rope. Disconnect. When the rope is cut, tension is applied to the rope by a tightening spring until then, so that the spring accommodating cylinder and the water-responsive cutting device are instantly separated from each other, and both of them are doubled. The stress applied in the direction disappears and the container and lid are opened.

The opened storage box accommodates a floating body to which a water responsive inflator or a drawstring traction inflator is attached, and the inflator is water responsive. At this time, when the rope is cut and the storage box is opened, water penetrates into the storage box and operates the water-responsive inflator to inflate the floating body. On the other hand, when the inflator is of a drawstring towing type, the tip of the drawstring is fixed to the lid, while the body of the inflator is fixed to the container, so the push-open spring opens the lid from the container. When it is moved in the direction, the drawstring is pulled and the inflator operates to expand the floating body.
Then, when the floating body accommodated in the storage box is smallly expanded and the stored floating body starts to expand due to the operation of the inflator, the floating body gradually comes out of the storage box and completely expands to form a floater.

In the water-responsive cutting device, it is like a paper which has a high tensile dry strength and loses its strength instantly when it gets wet with water. It is a stopper formed by binding several blocks.
Receives the pressure of the actuating spring via the drive shaft. When water enters the water-responsive cutting device, the stopper breaks and the force of the operating spring becomes an impact force, which is transmitted to the cutter via the drive shaft and moves in the direction of the rope.
The blade of the cutter is provided with a taper, and the rope that is stretched is cut together with the elastic tube under one blade.

In the tightening device, the rope is connected in advance with a predetermined length of the tightening spring accommodating cylinder and the water responsive cutting device so that the tightening spring can be attached to the storage box while being compressed. Also, it is designed so that it can be removed from the storage box.

[0037]

Since the present invention has the above-mentioned structure,
The life preserver of the present invention accommodates the floating body constituting the floater in a storage box, and the storage box is always kept in a watertight state by a fastener with a rope stretched. It can be attached to the mast, and in case of emergency, it does not require manual work such as taking it out from the cabin as in the past. The above-mentioned attachment can be done by relatively easy manual work such as binding, and it is also easy to remove, so you can take it home when you are not sailing,
Loss can be prevented.

The life-saving float of the present invention can be operated by hand in an emergency such as when the ship capsizes.
The water-responsive cutting device is activated, and the floating body is automatically expanded and formed outside the storage box.

The tightening tool according to the present invention comprises a rope stretched by a tightening spring and a water responsive cutting device, and the rope is water resistant and can be completely cut by a sharp blade. When the water-responsive cutting device is activated, it is completely cut in one operation, and the tightening force is lost to open the containment box.

The rope has many voids in both the yarn and the strand, and the surface is not smooth. Therefore, the rope has the property of absorbing water and transmitting it internally.

Since the portion of the rope used in the fastener of the present invention in the water-responsive cutting device is covered with the elastic tube, seawater or rainwater will enter the water-responsive cutting device. It is possible to prevent accidental natural operation without doing.

Although the rope has an attribute that it is stretched when a tension is applied, since the rope in the present invention is stretched by a tightening spring, the container of the storage box can be stretched even if some stretch occurs. The force that holds the lid and the lid is not lost. Therefore, the storage box is always tightened, while the rope is stretched.

With the tightening tool of the present invention, the tightening can be released manually. That is, the lock that fastens the storage box.
Since the spring is stretched by the tightening spring, the spring is manually compressed further, that is, in the embodiment, the spring receiving cylinder is manually gripped and the rope is moved in the direction to move out of the notch. As a result, the tightening device can be removed from the overlapping surface portion. Therefore, an unexpanded or inflated buoy can be thrown from the ship to, for example, a victim in water.

Since the storage box according to the present invention opens the lid when the tightened state is released, the gas inflator attached to the floating body can be either a drawstring towing type or a water responsive type.
