Description

[Detailed explanation of the invention] (Industrial application field) This invention relates to lifesaving equipment worn by crew members and passengers on board pleasure boats and other vessels. The vest changes into a swim bladder at the same time as the swimmer dives into the water.

(Prior Art) Conventionally, a life jacket that covers the whole body from the tips of the feet to the head is shown in Figure 1 of Publication No. 1983-32078 (Figure 8 A and B of the drawings of the present application). There is. Briefly explaining FIG. 8 A and B above, the suit body 40 integrally forms a lower body part 42 and an upper body part 43 from a shoe part 41, and extends vertically from the upper body part 43 to the lower body part 42. A head hood 45 is either integrally molded or separately molded on the suit body 40 and can be attached or detached using fasteners or the like, and an upper body portion 43 is provided on the chest and shoulders. An air bag 46 is attached to the inside of the air bag 46, and an intake/exhaust hose 47 communicating with the outside is provided on the air bag 46.

In the case of the above, air bags filled with a predetermined amount of air are attached to the chest and shoulders of the suit body, and when the suit body is worn, the arms and upper body are Not only was it impossible to move, but since the lower body and even the shoes were integrated, it was extremely difficult to move using the feet and hands. Furthermore, in the unlikely event that a drowning person sank into the sea or river, it was impossible to confirm their location.

In addition, the front body has a double structure and the pocket has the same planar area as the front body.
There is one shown in Figure 1 of Publication No. 42885 (Figure 9 of the drawings of the present application). To briefly explain FIG. 9 above, both front bodies 51, 51a of the vest 50 are made by cutting the outer material and lining in two layers and sewing them together along the cutting line.
The separately cut back body 52 is sewn into the vest 50 by normal sewing, and the front body 51, 51 is sewn into the vest 50.
Pockets 54, 54 having vertical openings 53, 53 for taking things in and out are provided along the front part of the figure a. The above items can be used to store bulky parts or tools that cannot be placed in a normal pocket while working in a high place or in a narrow space, and are designed to make it easy to take them in and out. If the item is inserted, it may come into contact with the wearer's body and cause pain, or the item may be pushed outward along with the front body in its original shape, making it difficult for the wearer to work with both hands.

(Problem to be solved by this invention) The problem to be solved by this invention is that the life preserver is worn on the upper body by the crew and passengers of pleasure boats and other ships, and they are always worn in vest condition. In the event of a shipwreck, the person can jump into the water with the life vest still attached, causing the life vest to inflate into a swim bladder.

(Technical means for solving the problem) The technical means taken by the present invention to solve the above problem is that the front body part and the back body part of the pair that constitute the form of a normal vest in appearance are A tube-structured elastic material made of rubber, synthetic rubber, or other similar materials with similar material properties is cut so that the insides of the left and right front body parts and back body parts are connected, and the separated shoulder parts and both A life vest is constructed in the form of a bag by welding, gluing, or other suturing methods from the arm opening and neck opening to the front, and a chest pocket for storing a gas cylinder is attached to the front surface of the left and right sides. A hook connecting the floating body is attached to the shoulder, and a colored floating body made of a highly buoyant material (e.g. foamed resin) or other material is provided, and a colored floating body is installed in the inner cavity of this floating body, with the tip attached to the hook. This floating body is equipped with a reel wound with a long length of string, and this floating body is attached to the outer surface of the rear body with a magic chuck (trade name) to the extent that it can be easily detached when subjected to water pressure. be.

(Function) If the ship is in distress while wearing a life vest and the crew members or passengers jump into the sea, the floating body will easily separate from the vest and rise to the surface of the water if they receive the impact of the jump. When the life vest ascends to the surface, it pulls out the airtight stopper of the gas cylinder connected to it with a short string, instantly filling the gas filling chamber with gas and creating buoyancy in the life vest. The upper body of a drowning victim is brought to the surface of the water, and the victim can be rescued in that state.

(Example) Hereinafter, an example of this invention will be described in detail based on the drawings.

In this embodiment, as shown in FIGS. 1 and 6, a life vest 1 has a tube-structured elastic material 2 made of rubber, synthetic rubber, or other similar material, and is a predecessor of the same form as a normal vest. The waist portions 3, 3a and the back body portion 4 are cut into a flat shape connected in a developed pattern, and the front body portions 3, 4 are cut along the cutting line.
3a and the back body part 4 at the shoulder part, U-shaped seam allowances 6, 6 for the arm loop part, and seam allowances 7, 7 for the front mating part that connects the collar part of the front body parts 3, 3a. By providing these seam allowances 5, 6, and 7, respectively, and joining them by adhesion, fusion, or other joining means, a gas filling chamber 8 through which all of the above-mentioned parts are communicated is constructed inside the life-saving vest 1. In FIGS. 1 to 6, a gas cylinder 9 is a normal small-sized one and is housed in a chest pocket 10 provided in the front body part 3, and its inlet valve 11 is connected to the gas cylinder 9 through a connecting pipe 12. It communicates with the filling chamber 8, and a seal plug 13 inserted into the inlet valve 11 is connected to a hook 16 provided on a floating body 15, which will be described later, with a string 14, and the length of this string 14 is the same as that of the life vest. The length of the seal plug 13 is such that it opens when the human body 20 wearing the water bottle 1 sinks about 30 to 40 cm from the water surface 21. The floating body 15 has a magic fastener 17 (product name) attached to one side, and is normally attached to a part of the rear body part 4, and is protected against strong forces such as falling into the sea, river, etc., or diving. It is designed so that when it receives an impact, it can easily separate from the rear body part 4 and float to the water surface due to the buoyancy of the material. The reel 18 is supported in the inner cavity 19 of the floating body 15, and the reel 18 has strings 14a from 5 to 5 colored in primary colors such as red and yellow so that they can be clearly identified even underwater.
By wrapping a length of approximately 10 m and connecting the end to the hook 16a provided on the shoulder of the life vest 1, it is possible to prevent the wearer of the life vest 1 from drowning in the event that he or she sinks below the surface of the water. The vivid colors of the floating body 15 and its string 14a are also arranged so that the whereabouts of a drowning person can be quickly confirmed.

Note that the symbol 20 in the figure indicates a human body.

Now, when a ship is in distress at sea or in a river, and the crew members and passengers jump into the water while wearing life vests, the impact of the jump causes the floating body 15 to instantly detach from the life vest 1, and the floating body 15 detaches from the life vest 1 due to its buoyancy. As it rises rapidly to the water surface, the seal plug 13 connected with a short string 14 is pulled out in the opening direction to open the valve, and the gas in the gas cylinder 9 is passed through the inlet valve 11 and the connecting pipe 12 to the gas filling chamber. 8 is instantaneously filled with gas, creating a predetermined buoyancy in the life vest 1,
This buoyancy gives buoyancy to the human body 20 of the victim who has once sunk below the water surface as shown in Figure 7A, and maintains the human body 20 so that the head appears above the water surface as shown in B, and maintains this floating posture. Wait for rescue. At this time, even if the life vest 1 of the victim wearing the life vest 1 does not have buoyancy, the string 14a is unwound from the reel 18 inside the floating body 15 and the floating body 15 is floated on the water surface, so that the life saving vest 1 can be suspended quickly. A drowning person can be brought to the rescue in a hurry, and life-saving measures can be applied to quickly revive the drowning person.

(Effects) Since this invention has the above configuration, it has the following advantages.

(1) This invention constitutes a life-saving vest having a gas-filled chamber in which the paired front and rear body parts are made of a tube-structured elastic material and communicate with each other except for the seam allowance, and the life-saving vest The airtight plug of the gas cylinder attached to the tank and the separately provided floating body were connected using the minimum necessary short string, so that when a person wearing a life vest jumps into the water, the impact of the water pressure causes the floating body to snap off the life vest. It easily detaches from the body and floats to the surface. At that time, the seal plug connected to the floating body with a string is opened, and the gas from the gas cylinder is injected into the gas filling chamber by the inlet valve, which inflates the life vest and creates buoyancy. , it is possible to reliably rescue a drowning person.

(2) Connect the hook of the life vest and the hook of a separate floating body with a string of the minimum necessary length, and use a string of the required length with the floating body and its inner cavity colored for easy identification. Since a reel wrapped with a life vest is built into the interior, even if a victim wearing a life vest sinks below the surface of the water, a floating body with an easily recognizable color can be connected to the life vest with an easily identifiable string and will be attached to the surface of the water. Since the drowning person is floating on the surface, it is possible to know the whereabouts of the drowning person immediately, take the drowning person in, apply life-saving measures, and quickly revive the drowning person. Additionally, if a swimmer wearing a life vest is about to drown, he or she can pull the cord of the seal with his/her own hand.

(3) Unlike conventional vests, it is not only easy to wear, but because it is tightly attached to the body like a normal vest, you can freely move your limbs while wearing it, making it suitable for use underwater. Not only does it make it easier to carry out activities such as swimming and swimming, but it is also extremely safe.
