Description

[Technical Field]

[0001] The present invention relates to a thong cover and footwear. [Background technology]

[0002] Wearing sandals, clogs, or other footwear with thongs for extended periods of time can cause thong chafing. To prevent this, thong chafing protectors and finger protectors are known.

[0003] For example, the finger protector in Patent Document 1 is a cylindrical body that can be inserted between the big toe and the index toe, and is formed with a through-hole through which the thong can pass and a slit through which the thong can be passed. By inserting the thong into the slit, the thong passes through the through-hole and the finger protector is attached to the thong. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2006-102312 Summary of the Invention [Problem to be solved by the invention]

[0005] However, the finger protector of Patent Document 1 cannot change its height, so it has a narrow range of applicability for the length of the thong.Furthermore, it cannot change the size of the through-holes or slits, so it has a narrow range of applicability for the diameter of the thong.

[0006] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a thong cover that can be adapted to a wide range of thong sizes, and footwear that uses the same. [Means for solving the problem]

[0007] The present invention is characterized by a thong cover that can be attached to a thong and that has an elastic spiral body.

[0008] The main body is preferably cylindrical, has a slit formed therein, and is formed in a spiral shape around the axis of the cylindrical body. The main body is preferably switchable between a cylindrical state and a spiral state and biased to the cylindrical state. The main body is preferably a molded product.

[0009] The footwear of the present invention is characterized by comprising the above-mentioned thong cover and a thong to which the thong cover is removably attached. [Effects of the Invention]

[0010] According to the present invention, it is possible to provide a thong cover that can be adapted to a wide range of thong sizes, and footwear using the same. [Brief explanation of the drawings]

[0012] As shown in FIG. 1, the beach sandals 2 (footwear) include a sole 10, a cross strap 20 attached to the sole 10, a thong 30 attached to the sole 10, and a thong cover 60.

[0013] The sole 10 is formed in a plate shape and is contoured to the sole of the foot.

[0014] The cross cord 20 is formed as a wire or a band, and one end 21 of the cross cord 20 is located midway in the front-to-rear direction of the sole 10 and is attached to one side in the width direction of the sole 10. The other end 22 of the cross cord 20 is located midway in the length direction of the sole 10 and is attached to the other side in the width direction of the sole 10. The middle part 23 of the cross cord 20 is located forward of the one end 21 and the other end 22.

[0015] The thong 30 is formed as a wire or a strip, one end of the thong 30 is provided at the front part of the sole 10, and the other end of the thong 30 is connected to the middle part 23 of the cross string 20.

[0016] The sole 10, the side straps 20, and the thongs 30 may be made of known materials such as rubber, elastomer, fiber, nonwoven fabric, etc.

[0017] The cross cord 20 may be formed integrally with the thong 30 or may be formed separately. In the latter case, it is preferable that the cross cord 20 is fixed to the thong 30.

[0018] The thong cover 60 is detachable from the thong 30.

[0019] 2, the thong cover 60 includes a main body 61. The main body 61 is a cylindrical body formed around an axis AX, and the thong 30 can be inserted into a through-hole 61X of the main body 61.

[0020] The material of the main body 61 has elasticity. Furthermore, the material of the main body 61 is preferably softer than the material of the thong. The material of the main body 61 is preferably, for example, a thermosetting elastomer, a thermoplastic elastomer, or other synthetic resin.

[0021] As the thermosetting elastomer, for example, natural rubber, silicone rubber, isoprene rubber, urethane rubber, ethylene propylene rubber, etc. are preferably used.

[0022] As the thermoplastic elastomer, it is preferable to use an olefin-based thermoplastic elastomer, a urethane-based thermoplastic elastomer, a styrene-based thermoplastic elastomer, or the like.

[0023] As shown in Figures 2 and 3, a slit 62 is formed in the main body 61. The slit 62 extends spirally around the axis AX of the main body 61. In addition, the slit 62 extends from the outer surface to the inner surface of the main body 61 in the radial direction of the main body 61. Therefore, the main body 61 can be freely switched between a cylindrical state (Figure 4) and a spiral state (Figure 5). In addition, it is preferable that the main body 61 be biased to the cylindrical state (Figure 4).

[0024] Next, how to use the thong cover 60 will be described.

[0025] First, the thong cover 60 is wound in a spiral state (Fig. 5). Next, the thong cover 60 is wrapped around the thong 30 to be worn. As a result, the thong 30 is inserted into the through-hole 61X (Fig. 6) in the main body 61 in the spiral state (Fig. 5). As a result, even when wearing the beach sandals 2 with the thong cover 60 attached, the big toe and index toe of the foot will not come into contact with the thong 30. As a result, rubbing of the toes on the thong 30 can be prevented.

[0026] Furthermore, when removing the thong cover 60 from the thong 30, the thong cover 60 can be removed from the thong 30 by pulling the end of the main body 61 in a spiral state (Figure 6) and operating it in the opposite direction to the spiral direction.

[0027] Because the thong cover 60 is formed in a spiral shape, it can deform in both the radial and longitudinal directions according to the dimensions of the thong to be attached. Therefore, the thong cover 60 can be attached to the entire thong 30, not only for thongs 30 of the same length as the main body 61, but also for thongs 30 that are longer than the main body 61. As a result, the thumb and index finger can be protected from rubbing against the thong 30. Furthermore, even if the diameter of the thong 30 is larger than the through-hole 61X of the main body 61, the main body 61 can be attached in a wrapped state around the thong 30. In this way, the thong cover 60 is adaptable to a wide range of thong sizes.

[0028] Furthermore, since the main body 61 has elasticity, a restoring force acts on the thong 30 when it is attached to the thong 30. As a result, the thong cover 60 easily wraps around the thong 30 and is less likely to fall off.

[0029] Because the main body 61 is biased into a cylindrical shape (Fig. 4), the thong cover 60 can be attached to the thong 30 over a wide range when in use (Fig. 1). Furthermore, when not in use, the thong cover 60 is compact, allowing for less storage space.

[0030] It is also preferable that at least the inner surface of the main body 61 is adhesive. This will maintain the spiral state of the main body 61 (Figure 5) when the main body 61 is attached to the thong 30, and will make the thong cover 60 less likely to fall off the thong 30. It is also preferable that the inner surface of the main body 61 is more adhesive than the outer surface of the main body 61. This will not only maintain the spiral state of the main body 61 (Figure 5) and make the thong cover 60 less likely to fall off the thong 30, but will also improve the feel on the toes.

[0031] Considering manufacturing costs, the main body is preferably a molded product.

[0032] In the above embodiment, the main body 61 is biased into a cylindrical shape (Fig. 4), but the present invention is not limited to this, and the main body 61 may be biased into a spiral shape (Fig. 5). This allows the thong cover 60 to be attached to a thong 30 that is shorter than the thong cover 60 when in use. Furthermore, when in use, both ends of the thong cover 60 press against the sole 10 and the cross strap 20, making it less likely for the thong cover 60 to fall off the thong 30.

[0033] In the above embodiment, a cylindrical main body 61 is used, but the present invention is not limited to this, and the main body may be a cylindrical body such as an elliptical cylindrical body or a square cylindrical body as long as it does not go against the spirit of the present invention.

[0034] In the above embodiment, the thong cover 60 is attached to the thong 30 of the beach sandals 2, but the present invention is not limited to this and can also be applied to footwear with thongs 30 such as zori, geta, suelas, and sandals (thong sandals, recovery sandals, flat sandals, lace-up sandals, etc.).

[0035] The present invention is not limited to the above-described embodiment, and it goes without saying that various modifications can be made without departing from the spirit of the present invention. [Explanation of symbols]
