Description

Functional shoes {A FUNCTIONAL SHOES}

The present invention relates to functional shoes, and more particularly, to functional shoes capable of selectively using a shoe function and a flipper function.

In general, unilaterally known flippers are worn and used during marine leisure activities such as skin scuba diving or swimming.

These flippers have a flat plate-shaped pin extending in the toe direction of the shoe-shaped foot wear portion so that the foot can be inserted and fixed, that is, a structure that is widely spread like a flipper.

After wearing the flippers as described above, if you stir up and down in the water, you can get a strong driving force in the water, and because of this, you can move far and quickly with little force.

However, the flippers as described above are very helpful when skin scuba diving or accommodation, but are inconvenient when walking on the ground or in water. Therefore, in addition to flippers, it is inconvenient to prepare and wear separate shoes, and to wear and use flippers when necessary.

Considering this point, the need for a new concept of functional shoes that include flippers has emerged.

In consideration of this point, functional shoes that can use both flipper function and shoe function have been proposed, such as Korean Patent Registration No. 10-1862290.

However, the conventional functional shoes as described above have a structure in which a flipper unit is installed in a folding manner with respect to the shoe body so that it can be unfolded and used only when necessary. .

In particular, when a fin unit with a complex structure is applied due to the nature of using it in water for a long time, there are problems such as easy breakdown and not operating normally, complicated manufacturing process, and increased manufacturing cost. there is.

In addition, the flipper unit must have the strength to withstand the resistance of water in the unfolded state. In the case of conventional functional shoes, the flipper unit protrudes from the shoe body in a plate shape, so it can be easily deformed by the resistance of the water, so the function of the flipper is There is a problem that does not perform normally.

In addition, Korean Patent Registration No. 10-2084736, filed and registered by the present inventor, solves the above problems, but when used as a flipper function in water, the strap does not adhere to the user's feet due to the resistance of the water, so the shoes are easily removed. there is

Republic of Korea 10-1862290 B Republic of Korea 10-2084736 B

The present invention has been devised in view of the above points, and the object of the present invention is to provide a functional shoe with a simple structure, improved water resistance, improved flipper function, and improved structure so that the shoe does not come off when used in water. there is

Functional shoes of the present invention for solving the above object, the shoe body; a flipper member that extends from the end of the shoe body in a plate shape, is used as a flipper function, and is deformed upward to be overlapped to cover the upper surface of the shoe body; a fixing unit for fixing the flipper member to be deformed to the upper surface of the shoe body and to maintain an overlapped state; and a strap that adheres to the shoe body and the back of the user's foot so that the shoe does not come off, and the strap is selectively folded or unfolded to adjust the contact area with the user's foot.

In addition, the strap, the main strap to which both ends are selectively fixed on the side of the shoe body; and a sub strap selectively folded to the main strap.

As a result, the shoe function and flipper function can be applied to one shoe for convenient use, and when used in water, the contact area with the user's foot is increased so that the shoe does not come off, and convenience can be increased by folding when used outside the water.

In addition, the sub strap may include an upper sub strap formed to be selectively folded at an upper end of the main strap; and a lower sub strap formed to be selectively folded at the lower end of the main strap.

Accordingly, it is possible to adjust the contact area with the foot according to the user's convenience by selectively folding or unfolding the top or bottom, or both the top and bottom, for the user's convenience.

In addition, it is preferable that a plurality of strap pins are formed in the main strap to be inserted into and fixed to the strap holes of the sub strap.

As a result, when folding, it is possible to stably maintain the folded state, thereby increasing user convenience.

On the other hand, according to a preferred embodiment of the present invention, the lower sub strap has a central portion formed with a groove, and the upper sub strap is formed in a shape corresponding to the groove when folded.

As a result, when the upper sub strap and the lower sub strap are folded, they do not interfere with each other, so that the strap is not thick even in the folded state, thereby increasing user convenience.

In addition, the fixing part preferably includes at least one fixing pin protruding from the upper surface of the shoe body, and the fixing pin is coupled to a fixing hole formed in the fin member.

Accordingly, when the flipper member is not in use, the shoes can be conveniently worn by being overlapped and fixed to the shoe body.

In addition, the flipper member may include a flipper member body connected in a plate shape at an end of the shoe body; and a deformation restraining unit formed at a lower portion of the flipper member body to allow the flipper member to be bent upward and to suppress downward deformation.

In addition, the deformation restraining part may include a plurality of cutouts formed on the lower surface of the flipper member body.

As a result, when the flipper member is used as a flipper function, it is possible to receive as much water resistance as possible to increase efficiency, and when not used as a flipper function, it can be easily bent and deformed and fixed to the shoe body.

According to the functional shoe of the present invention, the function of the aqua shoe and the function of the flipper can be implemented in one shoe and used selectively, and the configuration is simple to increase productivity and reduce manufacturing cost.

In addition, when using in the water, the strap fixed to the user's foot is extended to increase the contact area with the user's foot so that the shoe does not come off, and when used outside the water, convenience can be increased by folding it.

In addition, it is possible to adjust the contact area with the foot according to the user's convenience by selectively folding or unfolding the top or bottom, or both the top and bottom, for the user's convenience.

In addition, it is possible to increase user convenience by stably maintaining a folded state during folding.

In addition, when the upper sub strap and the lower sub strap are folded, they do not interfere with each other, so that the strap is not thick even in the folded state, thereby increasing user convenience.

Therefore, there is no need to separately prepare and carry aqua shoes and flippers as in the prior art.

In particular, when the flipper member is not in use, it can be conveniently used because it does not interfere with walking by overlapping and fixing it on the shoe body in a folded state.

Hereinafter, functional shoes according to embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 3, the functional shoe 100 according to the embodiment of the present invention includes a shoe body 110 that can be worn by inserting the user's foot, and flippers connected to the end of the shoe body 110. A member 120 and a fixing part 130 for fixing the flipper member 120 to the shoe body 110 in a state of overlapping with the shoe body 110 are provided.

The shoe body 110 may be made of a synthetic resin material similarly to general aqua shoes, and has a foot insert 111 that is worn by inserting a foot. In addition, a strap 113 is connected to the shoe body 110 to surround the back of the foot inserted into the foot insert 111 so that the shoe does not come off.

One end of the flipper member 120 is connected to the end of the shoe body 110 and extends to a predetermined length as a plate structure. It is preferable that the flipper member 120 is formed of a material having elasticity so as to cover the upper part, that is, the upper surface 115 of the shoe body 110 at the portion connected to the shoe body 110 so as to be deformed and restored in the overlapping direction. For example, the flipper member 120 has a plate-like structure and is preferably formed of a synthetic resin material having elasticity. Of course, the flipper member 120 may be integrally formed of the same material as the shoe body 110, or may be separately manufactured and combined.

In addition, the flipper member 120 includes a plate-shaped flipper member body 121 and a deformation restraint that prevents the flipper member 120 from being easily bent in a direction covering the upper portion of the shoe body 110 and not bent in the opposite direction. (123). The deformation restraining portion 123 includes a plurality of cutouts 123b spaced apart from each other on the lower surface of the flipper member body 121 .

The cutout 123b is formed by being cut to a predetermined depth from the lower surface of the flipper member body 121, and is preferably formed at regular intervals. In this way, when the cutout 123b is formed, upward bending of the flipper member 120 is allowed, and downward bending is suppressed. In particular, the cutouts 123b are arranged at regular intervals in the longitudinal direction of the flipper member 120, so that the flipper member 120 is easily deformed in an upper direction, the cutout 123b) is widened, , The rolling angle may be determined by the width of the wall portion 123a between the cutout portions 123b. According to this configuration, the flipper member 120 can be deformed into a shape that easily rolls upward while the cutout 123b is widened. In addition, in the flipper member 120, in the opposite direction, that is, in the unfolding direction, the cut surfaces of the cutout portions 123b come into contact with each other, and the protruding portion 123a receives a compressive deformation restraining force, thereby preventing deformation in the opposite direction. Therefore, when used in water, the flipper member 120 can receive the maximum resistance of the water and suppress downward deformation due to the resistance of the water. Therefore, the shape of the fin member 120 is maintained to receive maximum water resistance, so that the user can effectively use it when swimming or skin scuba diving.

In addition, more preferably, the flipper member 120 is formed of a flexible material as much as the depth at which the cutout 123b is formed, and a certain thickness of the upper portion where the cutout 123b is not formed prevents tearing and changes the shape. It may be formed of a synthetic resin material having a small strain rate so as to be maintained. That is, the flipper member 120 is divided into an upper layer and a lower layer, and the upper layer is preferably formed of a material that is stronger in strength and resistant to tearing than the lower layer.

When the flipper member 120 is not in use, the fixing part 130 is folded as shown in FIG. 3 and fixed to the top of the shoe body 110 in an overlapped state. The fixing part 130 includes a plurality of fixing pins 131 installed on the top of the shoe body 110 . A pair of the fixing pins 131 are disposed spaced apart from each other on the upper part of the shoe body 110 and are formed to protrude from the shoe body 110. Preferably, the fixing pin 131 is formed integrally with the shoe body 110, and the upper end is formed thicker than the lower part to prevent the fixing hole 125 formed in the flipper member 120 from easily falling out. there is.

A plurality of fixing holes 125 formed in the flipper member 120 are spaced apart from each other to correspond to the number of fixing pins 131, and are formed biased towards the free end of the flipper member 120. Therefore, as shown in FIG. 3, in a state in which the flipper member 120 is folded and overlapped to cover the upper part of the shoe body 110, the fixing hole 125 can be inserted into the fixing pin 131 to be fixed. Therefore, in this state, it can be worn like a normal shoe, and unlike conventional flippers, the flipper member 120 does not come into contact with the ground, so it does not interfere with walking.

On the other hand, the strap 150 according to a preferred embodiment of the present invention can be selectively folded or unfolded as shown in FIGS. 4 and 5 to adjust the contact area with the user's feet. When used as a flipper in the water, as shown in FIG. 5, the water resistance is increased by the flipper member 120 in addition to the water resistance, so that the shoes can be easily taken off, but the strap 150 is unfolded and the user's feet The contact area with the surface is large, so it is not easily peeled off. In addition, when the strap 150 is unfolded when used outside the water, it may be inconvenient to use, so the strap 150 may be folded and used as shown in FIG. 4 .

These straps 150 include a main strap 151 selectively fixed at both ends rotatably on the side of the shoe body 110 and sub straps 152 and 153 that are selectively folded or unfolded to the main strap 151. ).

The sub straps 152 and 153 include an upper sub strap 152 formed to be selectively folded at the top of the main strap 151 and a lower sub strap 153 formed to be selectively folded at the bottom of the main strap 151. It is preferable to include.

With this three-stage strap (151) (152) (153) structure, the user can selectively expand only the upper sub strap (152) or only the lower sub strap (153), or the upper and lower sub straps (152) (153). ) can be expanded or applied to suit the user.

Meanwhile, according to a more preferred embodiment of the present invention, a groove portion 153b is formed in the center of the lower sub strap 153, and the upper sub strap 152 is formed in a shape corresponding to the groove portion 153b.

With this configuration, even when the upper sub strap 152 and the lower sub strap 153 are folded to the main strap 151, they do not interfere with each other, and even if the three-stage folding structure is taken, only the thickness of the two-stage structure is implemented. This makes it possible to increase user convenience.

At this time, the main strap 151 is formed with a plurality of strap pins 151a into which the strap holes 152a and 153a formed in the sub straps 152 and 153 are inserted and fixed, so that the folded state can be firmly maintained. do.

The strap 150 configured as described above is elastically deformed toward the foot insertion part 111 in a state where the user's foot does not interfere when folded or folded, so that the folding lines 155 and 157 are folded or unfolded in a straight line state, , When using, the user's foot is inserted into the foot insertion portion 111, and the folding lines 155 and 157 of the strap 150 maintain a curved state rather than a straight line, so that the state can be maintained without folding or unfolding.

On the other hand, as shown in Figure 6, it is also possible to configure the strap 150 'of the two-stage structure without employing the strap 150 of the three-stage structure.

As described above, the functional shoe according to the embodiment of the present invention can be worn in a state where the flipper member 120 is folded and fixed to cover the upper surface of the shoe body 110 in normal times. In addition, during leisure activities such as swimming or skin scuba diving, the fin member 120 may be unfolded and used as shown in FIG. 2 .

Therefore, as in the prior art, without the need to separately prepare and carry the flipper member and the shoe, it can be conveniently used by transforming it into a single functional shoe according to the purpose of use.

In particular, in the case of the present invention, in a state where the flipper member 120 is connected to the shoe body 110, the top is easily deformed and the bottom is deformed, so that when used as a flipper function, water is prevented from being deformed. resistance can be made as large as possible.

In addition, since the connection and coupling structure of the flipper member 120 and the shoe body 110 is simple, and the configuration of the fixing part 130 coupling the flipper member 120 to cover the shoe body 110 is also simple, the product It has the advantage of shortening the manufacturing process and reducing manufacturing cost.

In addition, there is an advantage in fundamentally solving problems such as failure or inoperability due to the small number of parts.

In addition, the contact area between the strap and the foot is increased so that the shoe does not come off in the water, and discomfort when walking can be minimized by folding it out of the water.

In the above, the present invention has been shown and described in relation to preferred embodiments for illustrating the principles of the present invention, but the present invention is not limited to the configuration and operation as shown and described. Rather, it will be appreciated by those skilled in the art that many changes and modifications may be made to the present invention without departing from the spirit and scope of the appended claims.
