Or reduce it so that the life jacket fits your body.

However, the conventional life jackets as described above are manufactured to have a buoyancy determined according to the size, and wear a life jacket that is suitable for the user's weight because it is to wear a life jacket of size in proportion to the height of the user wearing a custom life jacket. Not only is this impossible, but there is no flexibility in the nature of the buoyancy material of the life jacket, so the operation of the upper body is greatly restricted in the state of wearing the life jacket. The buoyancy force acts on the torso between the chest and the lower back, so that it is not injured vertically on the water surface and is always inclined, and there is no buoyancy below the waist. Wearer has a lot of physical strength, There is a problem that it is difficult to cope quickly, can not be used as a swimming aid when learning various types of swimming (law), and also can not produce a variety of fashion within the range of safety.

The present invention has been made in view of the conventional problems as described above, the purpose is to wear buoyancy according to the user's intention as well as the life-saving function of the conventional water surface to simply float on the upper surface of the human body to wear on the upper body It can be easily adjusted or used for various water leisure activities by floating or dividing, and it is very free on the ground such as the beach, and the buoyancy increase can be performed quickly and easily according to the user's weight. Life jackets with appropriate size and buoyancy can be worn according to body type and weight.They can cover the front and back of the hips with exposure of well-groomed parts of the body. It can be used as a swimming aid when learning how to type, and when someone is drowned, It is possible to save lives quickly and safely by removing and removing the lower part of the life jackets worn by oneself and throwing it to a drowning person or wearing it on the torso. It is to provide a multifunctional life jacket equipped with a function.

An object of the present invention is a life vest manufactured by using a buoyancy material in the shape of a vest to wear it on the upper body of the body when water sports, the life vest is the upper member surrounding the chest and shoulders; The lower member surrounding the body can be achieved by a multi-function life jacket, characterized in that formed detachably separated from each other.

And an explanatory diagram illustrating a state in which horizontal injuries are performed, and FIG. 28 is a state diagram illustrating a state in which a human body is rescued by removing a lower member of the multifunction life jacket according to the present invention.

1 and 2, the multifunction life jacket 10 according to the present invention is composed of an upper member 20 and a lower member 40.

The upper member 20 is a portion surrounding the chest and shoulders in the vest form, the lower member 40 is a portion surrounding the body portion between the lower and lower chest.

The upper member 20 and the lower member 40 are detachably coupled to each other by the connecting member 50. That is, the connecting member 50 is mounted at a corresponding position along the lower end of the upper member 20 and the upper end of the lower member 40, respectively, and the upper member 20 is coupled to the connecting member 50. And the lower member 40 has the form of a normal life jacket, the upper member 20 and the lower member 40 is separated from each other when the coupling between the connecting member 50 is released.

In addition, the lower member 40 is composed of an upper portion 41 and a lower portion 42 as shown in Figure 3, the upper portion 41 and the lower portion 42 is not formed separately but is formed integrally It has a hinge portion 43 that can be easily folded along the side end middle portion is a folding structure that the lower 42 side can be folded to the upper 41 side.

The lower member 40 having such a folding structure includes a folding connection member 41a mounted on the upper end of the upper 41 side, and a folding connection member 42a mounted on the lower end of the lower 42 side, respectively. The corresponding connecting members 41a and 42a are detachably coupled to each other so that the folding state can be maintained, thereby folding the lower part 42 of the lower member 40 so as to overlap the upper part 41 when necessary. The buoyancy can be concentrated to one side by keeping the folded state.

That is, when the upper member 20 and the lower member 40 are in a coupled state, if the lower portion 42 of the lower member 40 is kept in the folded state at the upper portion 41, the buoyancy of the life jacket 10 is worn by the wearer. By focusing above the navel (preferably to the upper part of the upper body as much as possible), the wearer can maintain a direct posture (vertical posture that is not tilted to one side) while imported. The maintenance of the upright posture is to maintain the wearer's breathing conditions as best as possible when blue on the water surface because the wearer's respirator maintains the state as high as possible. In particular, in order to more effectively realize the concentrated buoyancy that concentrates the buoyancy to the upper part of the upper body, it is preferable that the lower member 40 is made smaller in height (vertical length) than the height of the lower part 42. That is, it is preferable that the height ratio of the upper portion 41 and the lower portion 42 is 1: 2 (the height of the lower portion 42 is 2/3 of the total height of the lower member 40).

5 to 7, if the wearer intends to horizontally float on the water surface, the lower member 40 is separated from the upper member 20, and then the lower member 40 is positioned at the hip region to raise the buoyancy. By dividing evenly into the lower and lower body to allow the wearer to easily rise on the water surface horizontally.

As described above, when the buoyancy of the life jacket 10 is divided into the upper body and the lower body, the lower member 40 flows due to various actions of the wearer, and the upper member 20 is prevented from being removed to the end of the lower body. ) And the life jacket 10 according to the present invention is provided with a connection band 52 so as to be firmly connected to each other and the lower member 40.

The connection belt 52 is a conventional belt, and has a connecting member 51 at both ends detachably coupled to the connecting member 50 of the upper and lower members 40.

In addition, if the wearer wants more free activity on the ground, it may be more free activity by separating the lower member 40 from the upper member 20 and then completely removed from the body, the upper member 20 only Wearing conditions are not limited to ground activities, they can guarantee free activity in the water, and insufficient buoyancy can be sufficiently compensated by the wearer's hand and foot movements. The swimming aids for mastering the type (law) or the type using the waist (law), etc. also have excellent functions. A more detailed description will be described later.

The state of wearing the upper member 20 and the lower member 30 on the upper body and the hip by separating the upper member 20 and the lower member 40 among the above-described wearing forms is not merely for horizontal injuries in the water phase. It is possible to produce eye-catching summer fashion by exposing the muscles and body of the torso made from the ground and at the same time, women can cover the front and back of the hips by the lower member 40 so that they can be vitally active even for women with a lot of shame. At the same time the back of the lower member 40 worn on the hips when sitting on the ground or the floor is naturally placed between the ground and the hips can also cushion function (see Figure 24).

25 to 27 shows a state of carrying out vertical and horizontal injuries or saving lives in water by wearing only the lower member of the multifunction life jacket according to the present invention.

25 to 27, the multifunction life jacket 10 according to the present invention can be carried out vertical and horizontal injuries by wearing only the lower member (40). That is, if only the lower member 40 is worn on the chest, the buoyancy is concentrated toward the upper part of the upper body, so that the wearer can easily be vertically injured in the water by the buoyancy effect such as wearing a ring-shaped air tube, and the lower member 40 ) When worn on the hips, buoyancy is worn on the middle of the human body so that the wearer can easily perform horizontal injuries, and in order to perform such vertical and horizontal injuries more effectively, the lower member 40 can be folded. It is good to wear.

Referring to Figure 28, while wearing a multi-function life jacket according to the present invention while water sports or water play when a situation that other people fall out of the water without the need to obtain a separate lifesaving tool from the upper member 20 quickly After removing the lower member 40 to remove from the body after folding the lower member 40 to fasten in the shape of a ring can be used as a lifejacket thrown in the water immersed in water, as well as multifunctional life jacket according to the present invention (10 In the situation where the wearer can quickly approach the drowned person by swimming, he quickly approaches the drowned person and terminates the emergency situation, and then removes only the lower member 40 of the wearer to get out of the water. It is possible to carry out life-saving safely and quickly by wearing it on.

19 and 20, the multifunction life jacket 10 according to the present invention freely performs vertical and oblique inclination injuries in a state where the upper member 20 and the lower member 40 are worn together. can do.

19 shows that the buoyancy is concentrated on the wearer's chest by wearing the lower member 40 in a folded state, thereby making it possible to easily perform vertical injuries. Such vertical injuries allow the wearer's respirator to be positioned higher than the water level so that the wearer can be easily centered while maintaining a safer injury state so that the wearer can freely use both hands to make mobile phone calls.

FIG. 20 shows that the wearer is naturally inclined by folding only the front of the lower member 40 so that only the front of the wearer generates the concentrated buoyancy, and the inclined injury in this state is as comfortable as the user is sitting in an armchair when the limb is removed. It can be injured in a posture, which is useful when you need to maintain a long period of injury.

Figure 23 illustrates a state in which the vertical injury by wearing only the upper member 20 of the life jacket 10 according to the present invention.

In this state, the wearer wears only the upper member 20, the vertical injuries are made without any action, but the buoyancy is weak so that the respiratory system of the human body is close to the surface, but the body can be used freely. Act) has the advantage to enjoy a safe swim, and can be used to enhance the buoyancy according to the intention of the wearer can increase buoyancy by the pursuit means to be.
