Description

Slipper Sandals {A Sandal usable as a slipper}

The present invention relates to a slipper combined sandals, which can be easily transformed into sandals and slippers according to a user's needs, while solving the problems of a decrease in the feeling of openness and a decrease in fit caused by a combination of slippers and sandals using conventional techniques. On the other hand, when used as sandals, it relates to a slipper combined sandals having a more improved fit.

Slippers and sandals are used for seasonal indoor and outdoor activities that do not require warming of the feet. Slippers are preferred as slippers because they have more openness and less pressure than sandals, and they are preferred to slippers for outdoor activities that require more formal and rapid activities. Sandals are usually not used and left unattended in the seasons when the feet need warmth due to their poor heat retention. Therefore, if the sandals can be transformed into slippers, the economical effect of improving the use value of the sandals and the cost of buying separate slippers can be obtained. Of course, if you can freely change your slippers to sandals, you can improve your ability to cope in emergencies like a fire.

Prior arts related to the present invention include shoes having a slipper combined sandal of Patent No. 0719159 and a detachable fixing body of Patent No. 0879557, footwear of Patent Publication No. 2006-0021328 and a manufacturing method thereof, and sandals of Utility Model Registration No. 0192615 , Utility Model Registration No. 071353, Functional Sandals, Utility Model Publication No. 2010-0003904 Sandals Function, Prefabricated Shoes of Patent No. 00505757, Japanese Patent Publication No. 2004-113812, Japanese Patent Publication No. 2010-42224 have.

In the prior art, even the band touching the ankle is called the instep binding band, or both the ankle binding band and the heel binding band are referred to as ankle binding band, but the present invention confuses the use of the name more clearly. For the sake of illustration, it is an instep binding band if it only touches the foot with a fixed position, an ankle binding band if it is formed separately from such band, and an ankle binding band if it touches the ankle, and is formed separately from the two previous bands. I want to distinguish.

In the case of slippers, the sole fixing position of the foot binding band should be at the front of the sole so that the foot is more open and less pressure is felt, thereby improving the fit. In the case of slippers, the rear end of the inseam binding band may be brought near the middle of the outsole for the purpose of reducing peeling by reducing the movement of the outsole. You must take the problem.

In the case of sandals, apart from such instep ties, the ankle bundling band should be fixed to the back of the sole (preferably near the point where the malignation has been cut from the ankle to the sole), while the heel fixing band should be fastened to the ankle bundling band for quicker foot movement. Nevertheless, the fit can be improved by minimizing the movement of the sole.

In other words, the sole fixing position of the instep binding band that can be maximized when used as a slipper is clearly different from the sole fixing position of the ankle binding band that can be maximized when used as sandals. In addition, the history of sandals has been proven to form an ankle strap and an heel band in a form that wraps the ankle and extends one of the bands to fix it at the back of the sole.

Strips that act as heel binding bands such as when the heel binding bands are fixed on the instep binding bands fixed to the front upper part of the sole as in Patent No. 0719159 and Utility Model No. 061353. Is fixed to the upper circumference of the upper opening or the like does not sufficiently consider the above-mentioned fact. In other words, the sole fixing position of the foot binding band that maximizes the comfort when using as a slipper is required to bear the inconvenience caused by the different fixing positions of the sole of the ankle binding band which can maximize the wearing comfort when used as sandals. There is a problem caused by omitting the ankle binding band which is an element.

In the case of Patent No. 0719159, the instep binding band is fixed to the back of the outsole so as to touch the ankle, which causes confusion in identifying the fixed position, but according to the claims, the instep incorporation band fixed to the front of the outsole is clear. . Instep straps fixed in this position are convenient for use as slippers, but when transformed into sandals, they must suffer from increased noise and reduced wear, such as peeling, due to severe movement of the sole.

Patent Publication No. 2006-0021328 proposes various fixing positions of a strip, but when fixed around the upper opening, if the position of the upper opening is the front part of the sole, there is a problem as described above. To avoid this, if the upper opening is moved to the back of the outsole, which is a fixed position of the ankle binding band, which is convenient when using sandals, the use of slippers reduces the opening of the foot and decreases the feeling of wearing by increasing the pressure applied to the foot. Has This problem also occurs when the instep binding band is located at the rear of the sole, as shown in Patent No. 0719159.

In the case of Patent No. 0879557, the fixture is installed at the back of the outsole, thus serving as an ankle binding band or an heel binding band. When the fixing body is used as a slipper that serves as an ankle binding band, the same problem as described above is used. Has

In the patent 0879557, when the fixture serves as the heel binding band, the position is fixed only by the frictional force with the connecting piece. The strip of Patent Publication No. 2006-0021328 serves as an heel binding band, and the exact position of the strip is maintained by the friction force with the portion where the rivet is installed. As such, when the heel binding band is kept in position only by the frictional force with a specific part of the shoe, the position can be maintained for a relatively short time immediately after wearing, so that the heel binding band that binds the heel may perform well. However, after prolonged use, the frictional force of the part and the movement and gravity of the foot gradually drop off from the heel, and it can not be avoided. To overcome this, it is necessary to bear the inconvenience of binding the heel by adjusting the length of the heel binding band from time to time, and increasing the pressure on the heel.

Utility Model Registration No. 0192615 is a technology that forms an integrated band to hold the ankle and the foot and uses it as a slipper by separating it in one-touch type.When using it as a slipper, the separated part must be carried separately from the shoe. Has

In the case of Utility Model Publication No. 2010-0003904, when the foot binding band is connected to the foot cover in a straight shape, the gap between the heel binding band and the foot cover is wide and easy to peel off, and the foot binding band is connected to the foot cover in the cross shape. Although the inseam binding band performs a part of the ankle binding band, the peeling can be reduced, but the heel binding band and the instep binding band are fixed relatively firmly to the rear of the sole and the foot cover, respectively, so that compared with the present invention, The friction is increased, there is a problem that the wear feeling falls.

Japanese Patent Application Laid-Open No. 2004-113812 has the inconvenience that the ankle binding band and the heel binding band have to be opened and taken out and put back in the storage lid each time, and the lid is lost or moved. Since the end of the heel binding band is hinged to the middle of the sole, the heel binding band is firmly fixed using an auxiliary band to prevent the movement of the sole. To secure it firmly to the heel strap or to easily store it inside the sole, the auxiliary band has no choice but to use hard material, which causes the foot to rub against these hard parts when worn, and inconveniently has to be stored or pulled out of the sole. There is this.

In Japanese Patent Application Laid-Open No. 2010-42224, the end of the heel binding band is hinged to the middle of the sole so that the movement of the sole is large and easily peeled off. To reduce the movement of the sole, the end of the foot cover is forced to come near the ankle, reducing the sense of opening. Even when using tension rubber or a spring-connected band to secure the heel binding band to the foot cover, the heel binding band is more elastic in contact with the foot, but it does not solve the fundamental problem of reducing openness. Additional height adjustment straps should be used to adjust the height of the band pulled up by rubber or spring. However, the function of this height adjusting line is clearly contrasted with the role of the pulling line in the present invention. In the present invention, because the pull string is connected to the elastic body and the coupling sphere, in addition to the function of limiting the maximum height of the band having a height adjustment line, it not only gives the ease of band storage, but also the elastic band as well as the heel binding band elastic Because it is worn on the foot and serves to fix the back part of the sole more flexibly, the friction and pressure are less felt compared to the method of fixing the band to the sole more firmly by the hinge method. Provide a fit.

The present invention is to solve the problems of the prior art as described above, to solve the problems of reduction of the feeling of opening and decrease of fit caused by giving the function of deformation while simply deformed to be used as slippers and sandals. It aims to accommodate both the advantages of slippers and sandals, while further providing slipper combined sandals with an improved fit when used as sandals.

In order to achieve the above object, the present invention provides an instep binding band that is fixed to the sole at a size and a position normally applied when used as a slipper; Ankle strap and heel strap for use as sandals; A pair of couplers coupled to both ends of the ankle binding band and the heel binding band such that the lower ends of the ankle binding band and the heel binding band are hinged to each other and rotate only within a limited angle range; A pulling string received inside the rear of the sole and exposed to the outside to be connected to the coupler; When used as a slipper, the two bands are mounted on the rear circumference of the sole in a state of being folded, when used as sandals, the two bands are spread within a limited angle range to provide slipper combined sandals worn on the foot do.

In a preferred embodiment of the present invention, the pull string pulls the two bands by an elastic body installed inside the sole so that the two bands are elastically mounted on the sole or worn on the foot.

The slipper combined sandals according to the present invention form an instep binding band at a convenient position and size when used as a slipper, and the other bands are superimposed and stably mounted around the rear circumference of the sole so that the original sense of openness of the slippers can be maintained as it is. It is possible to solve the deterioration of wearing comfort due to the reduction of the opening feeling caused by the backward movement of the instep binding band to combine the sandals proposed by the technology. In addition, when using the slipper combined sandals of the present invention, the ankle binding band and the heel binding band are kept within a limited angle by the connector and elastically fixed to the sole by a pull line connected to the elastic body built in the sole before and after Because of the characteristic of the cord that the movement of the left and right is more free, it is possible to obtain a superior fit than when the existing two bands are molded in one piece and fixed to the sole. It is effective in eliminating discomfort due to the fluctuation of the sole and the increase of noise, which are problems caused by the sandals combined with the conventional slippers and the sandals with the foot binding band in the upper part of the sole, which is a convenient position when the slippers are slippers. You can get it.

Therefore, the slipper combined sand proposed in the present invention can be freely changed into sandals and slippers according to the user's needs, but when used as a slipper, the band is more easily mounted and accommodated without loss of the slipper which is the biggest advantage of the slipper. When used as sandals have the effect of providing a more improved fit.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

The present invention is the foot binding band 21 is fixed to the sole 10 in the size and position that is usually applied when using as a slipper as shown in Figure 1 to 6; Ankle binding band 22 and heel binding band 23 for use as sandals; The pair of lower ends of the ankle binding band 22 and the heel binding band 23 are hinged to each other and coupled to both ends of the ankle binding band 22 and the heel binding band 23 so as to rotate only within a limited angle range. A coupler 30; A pull line 40 received inside the rear of the sole 10 and exposed to the outside so as to be connected to the coupler 30; When used as a slipper, the two bands 22 and 23 are mounted around the rear circumference of the sole 10 in a superimposed state, and when used as sandals, the two bands 22 and 23 are limited angles. It is spread out within range to be worn on the foot.

In the present invention, the pull string may be made of a material having elasticity as well, in the case of using a material having no elasticity, as shown in FIG. 3 by the elastic body 50 installed inside the sole 10 as shown in FIG. By pulling the two bands 22 and 23, the two bands 22 and 23 are elastically mounted on the sole 10 or worn on the foot.

As the elastic body 50, a spring or a rubber band may be used, which will be described in more detail in the related part.

The sandals of the present invention is fixed to the sole 10 in the size and position that is normally applied when using as a slipper so that there is no discomfort without the reduction of the advantages of the slipper to maximize the openness even when used as a slipper To form. For example, the contour and position of the front end of the foot binding band 21 may use the contour and position of the line connecting the end of the first toe of the big toe and the end of the toe, and the rear end may cover about 1/2 of the instep of the foot. If you make it, it will not be very uncomfortable even when used as a slipper.

On the other hand, the ankle binding band 22 and the heel binding band 23 is hinged to each other by a coupling 30, the coupling 30 is to rotate only within a limited angle range. As a result, when used as a slipper, as shown in FIGS. 2 and 6, the two bands 22 and 23 are mounted on the rear circumference of the sole 10 in a state of being folded back and forth with each other to be stepped on or touched by the foot. It can be avoided, and when used as sandals, as shown in Figs. 1 and 5, they are spread within a limited angle range to make it easier for the user to wear the shoes.

A part of the rear circumference of the sole 10 is formed in a step shape so that the ankle binding band 22 and the heel binding band 23 do not touch the ground without being inconvenienced by stepping on or touching the foot when used as a slipper. It is intended to be mounted without

In addition to this, including a protrusion 111 formed at the end of the insole 11 as a whole, a short-shaped groove 101 is formed in the rear end of the sole 10 to receive the two bands 22, 23 stably. It is possible.

As shown in FIG. 4, the coupler 30 may have a rectangular hole 301 at one end thereof to facilitate the connection of a band of various materials including plastic, cloth, leather, and the like. And, each of the coupler 30 at both ends of the ankle binding band 22 and the heel binding band 23 is formed in a male and female pair.

Both ends of the ankle binding band 22 connects the female coupler 302, and both ends of the heel binding band 22 connect the male coupler 303.

The male coupler 303 has a plurality of coupling protrusions 304 formed at the edges of the concentric circles. Then, the female and male couplers 302 and 303 are efficiently coupled by the elasticity of the coupling protrusion 304 by pushing the coupling protrusion 304 into the hole 305 in the female coupler 302.

The male coupler 303 is provided with a rotation limiting projection 306 which functions to limit rotation, and the female coupler 302 is formed with a rotation limiting depression 307. It is appropriate that the spread angle of the rotation limit depression 307 is set to 70 to 150 degrees.

When the rotation limiting projection 306 strikes both ends of the rotation limit depression 307, the coupler 30 can no longer rotate in that direction. In the center of the male coupler 303 is formed a hole 308 for fixing the pull string (40). Then, the string 40 can be easily connected to the male coupler 303 by putting a knot after passing through the hole 308.

The ankle binding band 22 is formed into two, but each of the free end variable length of the ankle binding band 22 by installing a binding port 24, such as a Velcro portion or a buckle having a male and female pair. It will be more convenient when you wear it.

When using sandals, the ankle binding band 22 and the heel binding band 23 are pulled off from the rear circumference of the sole 10, and then pulled out by pulling the pull string 40 stored in the sole 10. When the two bands 22 and 23 are opened within a limited angle range and the binding holes 24 are separated, the foot is inserted, and the binding holes 24 are combined again to complete the wearing.

3 shows an internal structure of the sole 10 in which the elastic body 50 is installed. Grooves in the midsole 12 is an example of using a plate-like spring as the elastic body (50). Various types of springs can be used, such as coiled springs and spiral springs. It is also possible to use other objects with the property of returning to a circular shape when pulled, such as rubber bands. For the comfort of the foot, the narrower the groove width for the installation of the elastic body 50 is better, and the piece of the midsole 121 that remains like an island is as wide as possible. From such a point of view, the most preferable elastic body 50 is a coiled spring or a spiral spring.

By forming a ring 41 at the end of the elastic body 50 and making a knot of the pulling line 40, the pulling line 40 can be easily connected to the elastic body 50. The pulling line 40 passes through the hole h and is connected to the coupler 30.

When used as sandals, it is desirable to limit the maximum length of the tug 40 drawn out of the hole h. To this end, the knot or the ring 41 of the tug 40 is formed larger than the hole h.

When used as a slipper, the ankle binding band 22 because the pull string 40 is received into the midsole 12 by the elasticity of the elastic body 50 and pulls the connector to the hole h. And the heel binding band 23 is elastically and semi-automatically mounted around the rear of the sole 10, and when used as sandals, the pull string 40 pulled to a proper tension by the elasticity of the elastic body 50 is Minimizes the movement of the sole 10, while reducing the noise produced by bumping the sole 10 and the sole during walking, while the two bands (22, 23) gently bind the ankle and heel to improve the fit will be.

When used as sandals, the location of the hole h from which the tug 40 emerges is preferably near the point where the user's ankle bone meets when mending from the astragalus to the midsole 12. Positioning the hole (h) in this way, because the pull line 40 allows the foot to move freely before, after, left, and right than the band usually used, the conventional ankle binding band 22 and the heel binding band 23 ) Can be formed integrally to provide a more comfortable fit by reducing friction than when the ankle binding band 22 is fixed in a similar position, and increase the fluctuation of the sole, which is a problem of sandals in combination with conventional slippers Of course, you can get the effect of reducing the noise caused by the soles and soles of the foot.
