Like reference numerals refer to like elements throughout.

1 is for explaining a multi-function underwater shoe device according to a first embodiment of the present invention, Figure 2 is an exploded description of the multi-function underwater shoe device according to a first embodiment of the present invention.

1 and 2, the multifunctional underwater shoe device 100 according to the first embodiment of the present invention is configured to include a support 110, a propulsion unit 120, and a fixing unit 130.

Support portion 110 is formed to a predetermined thickness and at least one detachable hole is disposed on the side side to support the user's foot as a whole. Support portion 110 is a propelling portion 120 is disposed on one surface, at least one or more removable holes penetrating the support portion 110 is disposed on the side surface. In FIG. 1 and FIG. 2, one removable hole is formed in the support part 110, but the present invention is not limited thereto, and a plurality of removable holes may be formed. As described above, at least one detachment hole is formed, the user may easily insert the fixing unit 130 into one of a plurality of detachment holes formed in consideration of the user's physical condition, foot size, adult or child. . Accordingly, the driving force generated in the water may vary slightly depending on the user.

In addition, the support 110 may have a wearing part 110b formed on the other surface of the supporting part 110, which is the opposite surface on which the propelling part 120 is disposed. The wearing unit 110b is to be worn by surrounding the user's feet or all the shoes worn by the user. This support 110 is four

The propelling unit 120 is fastened to the detachable hole through the fixing part or separated from the detachable hole, and when fastened to the detachable hole between the first angle and the second angle different from the first angle according to the foot motion of the user operating underwater. To let the user go forward underwater. That is, the user usually separates the propulsion unit 120 from the desorption hall and uses it as shoes or sandals, and in the case of playing in the beach or the river, the propelling unit 120 is fastened to the desorption hole 111 underwater. Use it as a shoe. At this time, the propulsion unit 120 adjusts the operation angle of the propulsion unit 120 according to the foot motion of the user moving underwater.

In addition, the driving unit 120 may further include an angle maintaining unit 121 to maintain the driving unit 120 between the first angle and the second angle while the user performs the foot motion. The angle maintaining part 121 is disposed on one side closest to the fixing part 130 of the propelling part 120 and is in contact with the supporting part 110 when the driving part 120 is the second angle. Here, the second angle may be the maximum angle at which the propulsion part 120 is widest from the support part 110. As such, by forming the angle maintaining part 121 in the propulsion part 120, the propulsion part 120 may maintain the second angle from the first angle in the water. Accordingly, the user can efficiently propel underwater in the direction desired by the user.

In addition, the driving unit 120 may form at least one hole penetrating the driving unit 120. As the hole is formed, the driving unit 120 may receive less underwater pressure received from the water. That is, a portion of the water passes through the hole when the propulsion unit 120 operates, thereby reducing the underwater pressure. Therefore, the user can move forward smoothly while using less power than when using a conventional underwater shoe device.

The width of the driving unit 120 described so far may be wider than the width of the support 110. In addition, the length of the propulsion unit 120 may be longer than the length of the support 110. As such, the reason why the propelling unit 120 is wider and longer than the supporting unit 110 is to further improve the driving force of the propelling unit 120 when the user operates the underwater shoe device. That is, the driving force increases as the area where the propulsion unit 120 contacts with water increases.

Here, the propelling part 120 formed wider and longer than the supporting part 110 may be formed in various shapes.

The fixing part 130 is inserted into or removed from the removal hole. The fixing part 130 penetrates and forms the propelling part 120 and the supporting part 110, thereby more firmly coupling the propelling part 120 and the supporting part 110, and at the same time according to the foot motion of the user in the water. It can work more smoothly. Here, when the fixing part 130 is separated from the detachable hole, the pushing part 120 and the supporting part 110 are easily separated.

In this case, the length of the fixing part 130 may be substantially the same as the width of the pushing part 120. Accordingly, the propelling unit 120 and the supporting unit 110 are more firmly coupled through the fixing unit 130, so that the propelling unit 120 is moved from the supporting unit 110 when the propelling unit 120 operates in the water. It is possible to prevent the departure.

Referring to FIG. 3, the multifunctional underwater shoe device 100 according to an exemplary embodiment of the present invention advances the user by operating between a first angle and a second angle different from the first angle according to the user's foot motion. Here, in FIG. 3, a is before the operation of the driving unit 120, and d illustrates the operation of the driving unit 120. The user may operate by alternating foot movements to proceed in the direction desired by the user underwater. At this time. The angle between the support 110 and the propulsion unit 120 may vary according to the user's foot motion.

The difference N between the first angle and the second angle, which is an angle between the support part 110 and the propulsion part 120, is 50 degrees or more and 170 degrees or less. In this way, by setting the difference N between the first angle and the second angle to 50 degrees or more and 170 degrees or less, the area where the propulsion part 120 and the water contact each other can be maximized or minimized according to the user's foot motion. Can be. Accordingly, the user can not only move faster and more propelledly in the direction that the user wants to proceed, but also operate efficiently.

In addition, if the difference between the first angle and the second angle, which are the angles between the support part 110 and the propulsion part 120, is equal to 0 as a, the same function as the conventional flippers is performed.

As described so far, the user can adjust the angle of the support 110 and the propulsion unit 120 in various ways according to the user's physical condition, so that the user can quickly move forward in the water.

4 is for explaining a multi-function underwater shoe device according to a second embodiment of the present invention, Figure 5 is an exploded description of the multi-function underwater shoe device according to a second embodiment of the present invention.

4 and 5, the multifunctional underwater shoe device 200 according to an embodiment of the present invention includes a support 210 and a propulsion unit 220.

Support portion 210 is formed by supporting the user's foot as a whole at least one or more removable grooves 211 is formed on one surface (210a). That is, the support unit 210 is to support the user's feet or shoes worn by the user while the user easily operates the multifunction underwater shoe device 200. At least one groove is formed in one surface 210a of the support part 210. The groove formed in the support portion 210 is configured to include a band fixing groove 212 and the removable groove 211. The band fixing groove 212 is to firmly fix the angle adjustment band to be described later, the removable groove 211 is engaged with the propelling unit 220 to be described later when the driving unit 220 is operated.

In addition, the support part 210 may have a wearing part 210b formed on the other surface of the support part 210, which is the opposite surface on which the removable groove 211 is formed. The wearing part 210b is to be worn by surrounding the user's feet or all the shoes worn by the user. In addition, the support 210 may be directly attached to the shoes worn by the user.

In addition, the support portion 210 includes a fixing hole 214a and a removal hole 213a. That is, the support portion 210 forms a fixing hole 214a penetrating the band fixing groove 212 on the side surface of the supporting portion 210 and includes a fixing pin 214 inserted into the fixing hole 214a. , Forming a detachment hole 213a penetrating the detachable groove 211 on the side surface of the support part 210, and includes a detachable pin 213 inserted into the detachable hole 213a.

Propulsion unit 220 is coupled to the removable groove 211 or separated from the removable groove 211, when combined with the removable groove 211 is different from the third angle and the third angle according to the user's foot movements moving underwater The user moves forward by operating between the fourth angles. That is, the user usually separates the driving unit 220 from the detachable groove 211 and uses it as shoes or sandals, and when playing in the beach or the river, etc., the user pushes the driving unit 220 to the detachable groove 211. It is used in combination with underwater shoes, etc. At this time, the driving unit 220 may vary the operation angle of the driving unit 220 according to the foot motion of the user moving in the water.

In addition, the propelling unit 220 is inserted into the detachable groove 211 on one side of the propelling unit 220 while being coupled to the propelling and detaching unit 221 for operating the propelling unit 220 between the third and fourth angles. To form. That is, the propelling unit 220 forms the propulsion detaching unit 221 to be inserted into the detachable groove 211 formed in the supporting unit 210, thereby easily fastening the propelling unit 220 to the supporting unit 210. In addition, the driving unit 220 may be operated smoothly at a predetermined angle in the water. In addition, the propulsion unit 220 may be a propelling contact portion 224 is formed in the remaining area of the one side of the propelling portion in which the propelling detachable portion 221 is formed except the portion where the propelling detachable portion 221 is formed. The propulsion contact 224 is in contact with the support 210 to allow the propulsion unit 220 to maintain a predetermined angle. The user can easily adjust the angle of the pushing unit 220 through the pushing detachable unit 221 and the pushing contact unit 224 formed on the pushing unit 220. Here, the pushing detachable part 221 may adjust the angle of the support part 210 and the pushing part 220 by changing the distance A from the pushing part 220.

In addition, the detachable pin 213 is disposed through the propellant detachable part 221, thereby more firmly tightening the propelling part 220 and the support part 210, and at the same time depending on the foot motion of the user.

The driving unit 220 forms at least one hole, and the hole formed in the driving unit 220 is fixed to fix the angle adjusting hole 222 and the driving unit 220 for adjusting the angle of the driving unit 220. And a dragon hole 223. That is, the angle adjusting hole 222 formed in the propelling part 120 is connected to the angle adjusting band fixed to the band fixing groove 212 and according to the foot motion of the user moving in the water support 210 and the propelling part 220 The angle of the liver can be appropriately adjusted by the length and elasticity of the angle adjusting band.

In addition, the fixing hole 223 by fastening the band fixing groove 212 or the support portion 210 and the driving unit 220 does not move, it can function substantially the same as the function of the conventional flippers.

In addition, a portion of the water subjected to underwater pressure may pass through the fixing hole 223 or the angle adjusting hole 222 formed in the driving unit 220 while the user operates the multifunctional underwater shoe device 200. Accordingly, the user can move forward smoothly while using less power than when using a conventional underwater shoe device.

The width of the driving unit 220 described so far may be wider than the width of the support 210. In addition, the length of the propulsion unit 220 may be longer than the length of the support portion (210). As such, the reason why the propelling unit 220 is wider and longer than the supporting unit 210 is to further improve the driving force of the propelling unit 220 when the user operates the underwater shoe device. That is, the driving force also increases as the area where the driving unit 220 contacts with water increases.

Here, if the support portion 210 is formed wider and longer than the shape of the driving unit 220 may be formed in various shapes.

Referring to FIG. 6, the multifunctional underwater shoe device 200 according to the second exemplary embodiment of the present disclosure moves forward the user by operating between the third angle and the third and other fourth angles according to the user's foot motion. . Here, in FIG. 6, a is before operation of the driving unit 220, and b in FIG. 6 illustrates operation of the driving unit 220. The user may operate by alternating foot movements to proceed in the direction desired by the user underwater. At this time. The angle between the support 210 and the propulsion unit 220 may vary according to the user's foot motion.

In this case, the user may change the angle between the support part 210 and the propulsion part 220 by using a gap A between the propellant detachment part 221 and the propulsion part 220. That is, as the distance A between the propellant detachable part 221 and the propelling part 220 changes, the part where the propelling contact part 224 contacts the support part 210 is changed, and the support part 210 and the propulsion part 220 are changed. ) Will change the angle between. The propulsion contact part 221 firmly supports the angle at which the propulsion part 220 is converted in the support part 210 by contacting the support part 210.

At this time, when the distance A between the propulsion detachable part 221 and the propulsion part 220 is short, the angle between the support part 210 and the propulsion part 220 becomes small, and the propulsion detachable part 221 and the propulsion part 120 are reduced. If the distance (A) between the longer the angle between the support 210 and the propulsion unit 220 is increased. Accordingly, the angle between the support part 210 and the propulsion part 220 shown in d is greater than the angle between the support part 210 and the propulsion part 220 shown in b, and the propellant detachable part 221. ) And the distance A between the propulsion unit 220 is long.

Accordingly, the user may mount the propulsion unit 220 having a different distance A between the propulsion detachable part 221 and the propulsion unit 220 according to the user's exercise amount or the surrounding environment. Propulsion detachable part 221 according to the case where the user operates while keeping the ankle in water substantially parallel to the user's calf and the user operates while maintaining the right angle with the user's calf without extending the ankle in the water. And a distance A between the propulsion part 220 and the other propulsion part 220 is mounted on the support part 210.

In addition, the difference between the third angle and the fourth angle, which is an angle between the support part 210 and the propelling part 220 formed through the gap between the propelling and detaching part 221 and the propelling part 220 described above, is 50 degrees. It is more than 170 degrees. In this way, by making the difference between the third angle and the fourth angle 50 degrees or more and 170 degrees or less, the area where the propulsion part 220 is in contact with water can be maximized or minimized in accordance with the user's foot motion. Accordingly, the user can not only move faster and more propelledly in the direction that the user wants to proceed, but also operate efficiently.

In addition, if the difference between the third angle and the fourth angle, which is the angle between the support portion 210 and the propulsion portion 220, is set to 0 as a, the same operation function as the conventional flippers is performed.

As described above, since the user can adjust the angles of the support part 210 and the propelling part 220 in various ways according to the user's physical condition, the user can quickly move forward in the water.

Referring to FIG. 7, the angle adjusting band 330 according to the third exemplary embodiment of the present invention is disposed between the support part 310 and the propulsion part 320.

The support portion 310 is configured to include a fixing pin 314 is formed in the fixing hole 314a penetrating the band fixing groove 312 on the side side of the supporting portion 310 and inserted into the fixing hole 314a, , The propulsion unit 320 is configured to include an angle adjusting hole 322. At this time, one end of the angle adjustment band 330 is fastened and fixed with the fixing pin 314 inserted into the fixing hole 314a, and the other end of the angle adjustment band 330 is the angle adjustment hole 322 of the driving unit 320. ) Will be tightened.

As such, by arranging the angle adjusting band 330 between the support part 310 and the driving part 320, the angle of the driving part 320 may be limited.

Referring to Figure 8, it shows that the angle adjustment band 330 operates according to a third embodiment of the present invention.

(a) is that the angle of the support portion 310 and the propulsion portion 320 is formed by changing the angle of the propulsion itself to reduce the resistance of the water or substantially 0 degrees, which means that the foot motion of the user from below It can form when the water is pushed up. In this way, since the angle of the propelling part changes itself so that the support part 310 and the propelling part 320 closely adhere to each other or reduce the resistance of the water, the resistance of the water is minimized when the water is pushed back.

(b) is that the angle of the support 310 and the propulsion unit 320 forms a predetermined angle by the angle adjustment band 330, which means that the user's foot movement in the water to the opposite side of the traveling direction Can be formed when operating from top to bottom. As such, when the water is pushed down in the water, the support portion 310 and the driving portion 320 can form a predetermined angle by the length and elasticity of the angle adjustment band 330, the user's foot operation The propulsion unit 320 can be operated even larger. Thus, the user can push more water out of the water. That is, the angle of the driving unit 320 may be greater by the elasticity of the angle adjustment band 330 than the angle of the user's foot movement. Since the propelling unit 120 can push more water by the larger angle as described above

Looking at Figure 9, it shows a variety of one surface (210a, 310a, 410a) of the support according to various embodiments of the present invention.

In this case, when at least one of the detachable grooves 311a to 311e is formed, at least one or more propelling detachable portions 321 inserted into the detachable grooves 311a to 311e may be formed. That is, the number of the detachable grooves 311a to 311e formed in the support part 310 and the number of the propellant detachable parts 321 formed in the propulsion part 320 are formed in substantially the same number.

Functions and effects on at least one of the at least one removable grooves 311a to 311e and the band fixing grooves 311a to 311e have been described above, and thus will be omitted here. In addition, various embodiments of the present disclosure are not limited to the multifunctional underwater shoe device 300 illustrated in FIG. 9, and may be variously changed.

support portions

210 and 310, respectively, or at least one of them is formed.

Looking at Figure 10, it is for explaining the one surface of the support portion (310d, 310e) according to another embodiment.

According to another embodiment of the present invention is to form only one removable groove (311f) in a portion of the support portion (310d). That is, one removable groove 311f is formed long in the support portion 310d. At this time, it is expressed as a removable groove (311f) it may be a band fixing groove. 10 (a) shows that only one detachable groove 311f is formed in a part of the support part 310d, and FIG. 10 (b) shows two

detachable grooves

311g and 311h in a part of the support part 310e. It is formed long side by side.

In addition, the

support portions

310d and 310e may form at least one or

more detachment holes

313a and 313b penetrating the

detachable grooves

In this way, by forming the removable grooves (311f, 311g, 311h) long on one surface of the support portion (310d, 310e) by forming at least one of the removable holes (313a, 313b) on the side surface of the support portion (310d, 310e). According to the user, the position of fastening the propelling part may be changed. Accordingly, the user can efficiently exert the driving force. That is, by changing the position of the propulsion unit according to the user, it can be fastened to fit the user with different motor nerves. Therefore, the thrust portion is substantially coupled with the user's motor nerves.

As such, when the user uses the propulsion part 320a in the water, the resistance of the water can be efficiently controlled. That is, since the propulsion part 320a has an arch shape, not only can the resistance of the water be increased efficiently, but also the ring shape 322a formed at the other side of the propulsion part 320a allows water to flow in a direction opposite to that of the user. I can push it. Accordingly, the driving force can be improved.

In the supporting portion 310g illustrated in FIG. 11B, an annular shape 322b is formed on the other side of the propelling portion 320b, which is opposite to one side of the propelling portion 320b on which the propelling and detaching portion 313d is formed. A part of the pushing part 320b may be formed in a bent shape.

By forming in this way, the area in contact with the water when the user uses the driving unit 320b in the water can be widened. That is, since a part of the propulsion part 320b is bent, the area in contact with the water is not only large, but the resistance of the water can be efficiently increased in the bent shape. Accordingly, the user can efficiently operate the driving unit 320b. Therefore, the user can easily proceed in the water or the direction he wants in the water.
