In addition, the main body 32 is provided with a pushing member 39 coupled to the packing bar 36 so as to elevate the packing bar 36 to protrude out of the main body 32. In other words, when the user pushes the pushing member 39 upward, the packing bar 36 opens the injection hole 33 and, on the contrary, when the user releases the pushing member 39, the original force is released by the elastic force of the spring 35. Returning to position, the packing bar 36 is also elastically biased by the spring 35 to close the inlet 33.

Hereinafter, the operation and effects of the portable buoyancy mechanism according to the preferred embodiment of the present invention having the configuration as described above will be described in detail.

As shown in Figures 4a and 4b, the user usually carries the buoyancy mechanism of the present invention, or wear it on the body. For example, in the case of playing in the water, the user wears directly in a suit or is carried by a safety officer or guardian. It is also worn in places such as belts B during flood training, camping in valleys and the like, and during training of military officers.

If the danger of drowning accident suddenly breaks out in such a usual situation, the user throws the buoyancy mechanism of the present invention on the subject of danger or seizes it from the body.

Referring to the following operation in more detail, as shown in Figure 5, first, the user releases the binding state of the handle portions (16a, 16b) that are mutually bound, and rotates in a circumferential direction. At this time, the handle portions 16a and 16b are caught by the stopper 17 during the rotation and spaced apart from each other by a predetermined interval. In this state, the handles 16a and 16b are lightly pressed. Then, the first and second cases 11 and 12 are formed at an acute angle such as a fan bone shape with respect to the support bolt 13. At this time, the first and second cases 11 and 12 are in a tensioned state by the compressive force of the elastic spring 18. In addition, the first and second cases 11 and 12 are supported by the first and second rods 15a and 15b. Here, the first and second rods 15a and 15b are folded in the cases 11 and 12, and when the cases 11 and 12 are opened, the first and second rods 15a and 15b are articulated about the pin member 14 to be unfolded in a straight line. The inlet 21a of the air bag 21 to be described later is formed in a substantially triangular shape together with the first and second cases 11 and 12.

That is, the inlet 21a is opened while the air bag 21 is supported by the first and second cases 11 and 12 and the first and second rods 15a and 15b.

Then, the handles 16a and 16b are pushed and shaken to the left and right. Then, the air in the atmosphere is injected into the internal space through the inlet 21a of the air bag 21, and the bag is inflated by the air. At this time, the air injected into the air bag 21 is introduced into the interior through the auxiliary injection pipe 22, the tension member 23 provided in the discharge port is relaxed due to the pressure of the incoming air, and is again contracted again The incoming air flows backward so that it is not discharged outward. That is, the tension member 23 is to reduce the width of the outlet so as not to flow back through the outlet.

In this way, after the air in the air is injected into the air bag 21, one of the handle portions 16a, 16b that are pressurized is released from the hand. Then, the handle portions 16a and 16b are released and the first and second cases 11 and 12, which are opened in a tense state, are returned to their original positions by the restoring force of the elastic springs 18. Thereafter, the handle portions 16a and 16b are rotated in the opposite direction to be engaged. Therefore, the inlet 21a of the air bag 21 is closed and air does not leak to the outside. At this time, since the air in the air bag 21 is injected by shaking the air bag 21 in which the inlet port 21a is opened, the air pressure is not so high. To compensate for this, the user blows the supplemental air into the air bag 21 using the valve unit 31. In detail, first, the pushing member 39 is lifted upward. Then, the packing bar 36 is raised while pressing the spring 35 to open the inlet 33, the extension 37 is spaced apart from the protrusion 38. Therefore, the user may blow air into the inlet 33. At this time, the injected air is injected into the air bag 21 through the plurality of outlets 34 formed in the main body 32, and when the supplemental air is injected, the pushing member 39 that is pushed is placed. The packing bar 36 is then returned to its original position by the spring 35 to close the inlet 33 (see FIG. 3).

As a result, the air bag 21 inflated with air is floated to the surface by the buoyancy and the user who is in danger of drowning accident is holding or holding the air bag 21 to swim.

On the contrary, the user swimming out of the water discharges the air injected into the air bag 21 and folds the air bag 21 into the first and second cases 11 and 12.

More specifically, first, the user opens the inlet port 21a of the air bag 21 in order to inject air into the air bag 21 to discharge the air present in the bag out. At this time, in order to completely discharge the residual air remaining in the air bag 21, pressing the bag in the state of lifting up the pushing member 39 of the valve unit 31 is completely discharged to the outside through the inlet 33 ( 3). As such, when the air is completely removed, the air bags 21 are folded and placed in the first and second cases 11 and 12 to bind the handle portions 16a and 16b to the front surfaces of the cases 11 and 12. To cover.

On the other hand, the buoyancy mechanism of the present invention may separate the air bag 21 from the first and second cases (11, 12) to be buoyancy. That is, the engaging bar 19 is pulled out from the binding opening (19a of FIG. 1) formed in each case 11 and 12. As shown in FIG. Then, the air bag 21 is detached from the coupling bar 19, and the part which is attached to the first and second rods 15a and 15b is removed completely from the first and second cases 11 and 12. do. Then, air is injected into the separated air bag 21 and the buoyancy is tied to the inlet port 21a of the bag with a connecting string (24 of FIG. 2). Alternatively, the connecting strap (24 of FIG. 2) may be tied to the user's body.

The present invention has been described in detail through specific embodiments, but the present invention is not limited to the above embodiments, and various design variations are possible by those skilled in the art within the scope of the technical idea of the present invention. .

As described above, the portable buoyancy mechanism according to the preferred embodiment of the present invention is easy to carry, safe, and can be injected immediately in a short time with a simple operation, so that in the event of an emergency situation, The advantage is that drowning can be prevented.
