Description

[Technical field]

[0001] The present invention relates to geta sandals. [Background technology]

[0002] Traditionally, geta sandals have been known as traditional Japanese footwear, and are often worn by men, such as tea masters and people of refined taste, when wearing kimonos. In recent years, new geta sandals that are different from traditional geta sandals, such as geta sandals for fashionable wear, have been proposed (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Utility Model Registration No. 3149871 Summary of the Invention [Problem to be solved by the invention]

[0004] However, conventional geta sandals do not incorporate any measures to reduce the shock to the heel when walking, and there is room for improvement in the comfort of geta sandals.

[0005] The present invention has been made in consideration of the above problems, and aims to provide geta sandals that can reduce the impact on the heel when walking and provide an unprecedented level of comfort. [Means for solving the problem]

[0006] The geta of the present invention is a geta composed of a base and a thong, the base comprises a top plate to which the thong is attached, an outsole member as a bottom plate, and a midsole member provided between the top plate and the outsole member, the midsole member and the outsole member being made of synthetic resin, the midsole member being provided with a hollow member at least at a position corresponding to the heel, and at the position corresponding to the heel, the ratio B / A of the thickness B of the hollow member to the thickness A of the base is set to be 0.2 or more and 0.7 or less.

[0007] According to this configuration, a hollow member is provided at least at a position corresponding to the heel inside the midsole member of the geta base, and the thickness B of the hollow member relative to the thickness A of the entire base at the position corresponding to the heel is set sufficiently large (the ratio of B / A is set to 0.2 or more), so that the impact on the heel during walking can be reduced compared to conventional geta (without a hollow member), and a comfortable fit that has never been seen before can be achieved. In this case, the thickness B of the hollow member relative to the thickness A of the entire base is not set excessively large (the ratio of B / A is set to 0.7 or less), so that the thickness of the top plate and the outsole member can be sufficiently ensured. By ensuring the thickness of the top plate, it is possible to avoid impairing the comfort of the geta, and by ensuring the thickness of the outsole member, it is possible to avoid impairing the durability of the geta.

[0008] In addition, in the geta of the present invention, at a position corresponding to the heel portion, the ratio D / C of the width D of the hollow member to the width C of the base may be set to 0.8 or more.

[0009] With this configuration, the width D of the hollow member relative to the width C of the entire base at the position corresponding to the heel is set sufficiently large (the D / C ratio is set to 0.8 or more), thereby reducing the impact on the heel when walking and achieving an unprecedented level of comfort.

[0010] In addition, in the geta of the present invention, the hollow member may be provided rearward of the position of a rear hole through which the cross strap of the thong is passed.

[0011] According to this configuration, by providing the hollow member rearward of the position of the rear hole, it is possible to reduce the impact on the heel when walking, thereby achieving an unprecedented comfortable fit.

[0012] In addition, in the geta of the present invention, the geta are configured to be symmetrical in a planar view with the center line of the geta as an axis, and the hollow member may be configured to be symmetrical in a planar view with the center line of the midsole member as an axis.

[0013] According to this structure, the sandals are symmetrically constructed, so by wearing the sandals alternately on the left and right, the wear on the outside and inside of the outsole members of the sandals becomes even, and the sandals can be worn for a long time. In this case, the hollow members are also symmetrically constructed, so the sandals can be worn comfortably the same whether worn on the left or right side.

[0014] In addition, in the geta of the present invention, the midsole member may be made of synthetic resin, and the hollow member may be provided inside the midsole member by manufacturing the midsole member by insert molding using the hollow member as an insert item.

[0015] According to this configuration, by making the midsole member from synthetic resin and manufacturing the midsole member by insert molding using the hollow member as an insert item, it becomes possible to easily manufacture the midsole member having the hollow member provided inside.

[0016] The geta of the present invention is a geta consisting of a base and a thong, the base having a top plate to which the thong is attached and a sole member as a bottom plate, the inside of the sole member having a hollow member at least at a position corresponding to the heel, the ratio B / A of the thickness B of the hollow member to the thickness A of the base at the position corresponding to the heel is set to be 0.2 or more and 0.7 or less.

[0017] According to this configuration, a hollow member is provided at least at a position corresponding to the heel inside the sole member of the base of the geta, and the thickness B of the hollow member relative to the thickness A of the entire base at the position corresponding to the heel is set sufficiently large (the ratio of B / A is set to 0.2 or more), so that the impact on the heel during walking can be reduced compared to conventional geta (without a hollow member), and a comfortable fit that has never been seen before can be achieved. In this case, the thickness B of the hollow member relative to the thickness A of the entire base is not set excessively large (the ratio of B / A is set to 0.7 or less), so that the thickness of the top plate and the sole member can be sufficiently ensured. By ensuring the sufficient thickness of the top plate, it is possible to avoid impairing the comfort of wearing the geta, and by ensuring the sufficient thickness of the sole member, it is possible to avoid impairing the durability of the geta.

[0018] In addition, in the geta of the present invention, at a position corresponding to the heel portion, the ratio D / C of the width D of the hollow member to the width C of the base may be set to 0.8 or more.

[0019] With this configuration, the width D of the hollow member relative to the width C of the entire base at the position corresponding to the heel is set sufficiently large (the D / C ratio is set to 0.8 or more), thereby reducing the impact on the heel when walking and achieving an unprecedented level of comfort.

[0020] In addition, in the geta of the present invention, the hollow member may be provided rearward of the position of a rear hole through which the cross strap of the thong is passed.

[0021] According to this configuration, by providing the hollow member rearward of the position of the rear hole, it is possible to reduce the impact on the heel when walking, thereby achieving an unprecedented comfortable fit.

[0022] In addition, in the geta of the present invention, the geta are configured to be symmetrical in a planar view with the center line of the geta as an axis, and the hollow member may be configured to be symmetrical in a planar view with the center line of the sole member as an axis.

[0023] According to this structure, the sandals are symmetrically constructed, so by wearing the sandals alternately on the left and right, the wear on the outside and inside of the sole member of the sandals becomes even, and the sandals can be worn for a long time. In this case, the hollow members are also symmetrically constructed, so the sandals can be worn comfortably the same whether worn on the left or right side.

[0024] In addition, in the geta of the present invention, the sole member may be made of synthetic resin, and the hollow member may be provided inside the sole member by manufacturing the sole member by insert molding using the hollow member as an insert item.

[0025] According to this configuration, by making the sole member from synthetic resin and manufacturing the sole member by insert molding with the hollow member as an insert item, it becomes possible to easily manufacture the sole member having the hollow member provided inside.

[Figure 10] FIG. 11 is an explanatory diagram (sectional plan view) of geta according to a second embodiment of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0028] (First embodiment) The structure of the geta according to the first embodiment of the present invention will be described with reference to the drawings. Fig. 1 is a side view of the geta according to this embodiment, and Fig. 2 is a plan view of the geta according to this embodiment. Fig. 3 is an exploded side view of the geta according to this embodiment. As shown in Figs. 1 to 3, the geta 10 is composed of a base 11 and a strap 12. The base 11 has a top plate 13 to which the strap 12 is attached, an outsole member 14 as a bottom plate, and a midsole member 15 provided between the top plate 13 and the outsole member 14.

[0029] The thong 12 is made of, for example, padded velvet, but is not limited to this, and a known thong used in conventional geta may be used. Although not shown, the top board 13 is made of a core material, a surface (front) provided on the core material, and a low-resilience cushion provided between the core material and the front. For the core material, for example, a wooden board or thick paper can be used. For the low-resilience cushion, for example, a foamed plastic material or a sponge material can be used. For the front, a woven material such as kasuri-dyed thread or rush grass can be used. The top board 13 is also not limited to the above example, and a known top board used in conventional geta may be used.

[0030] A hollow member 16 is provided inside the midsole member 15 at a position corresponding to at least the heel part (see also Figs. 4 and 5). Here, "the hollow member 16 is provided inside the midsole member 15" means that most of the hollow member 16 is provided inside the midsole member 15, and a part of the hollow member 16 may be exposed to the outside of the midsole member 15.

[0031] As shown in FIG. 4, the ratio B / A of the thickness B of the hollow member 16 to the thickness A of the base 11 at the position corresponding to the heel is set to 0.2 or more and 0.7 or less, more preferably 0.3 or more and 0.6 or less. As shown in FIG. 5, the ratio D / C of the width D of the hollow member 16 to the width C of the base 11 at the position corresponding to the heel is set to 0.8 or more, more preferably 0.9 or more. In the example of FIG. 4, the ratio B / A of the thickness B of the hollow member 16 to the thickness A of the base 11 is 0.357, and in the example of FIG. 5, the ratio D / C of the width D of the hollow member 16 to the width C of the base 11 is 0.967. Here, the thickness B of the hollow member 16 refers to the maximum value of the thickness of the hollow member 16. For example, when the thickness differs depending on the part of the hollow member 16, the thickness value of the part of the hollow member 16 that is the thickest corresponds to the thickness value.

[0032] As shown in Fig. 5, the hollow member 16 is provided behind (to the heel side, on the right side in Fig. 5) the position P of the rear hole 17 through which the cross strap of the thong 12 passes. As shown in Fig. 2, the geta 10 is configured symmetrically in a plan view with the center line L of the geta 10 as an axis, and as shown in Fig. 5, the hollow member 16 is configured symmetrically in a plan view with the center line Lm of the midsole member 15 as an axis. In this embodiment, the center line L of the geta 10 and the center line Lm of the midsole member 15 coincide in a plan view.

[0033] The midsole member 15 is made of synthetic resin, and is manufactured by insert molding using the hollow member 16 as an insert, thereby providing the hollow member 16 inside the midsole member 15. Examples of materials that can be used for the midsole member 15 include PU (polyurethane), PVC (polyvinyl chloride), and EVA (ethylene vinyl acetate).

[0034] The outsole member 14 is also made of synthetic resin, and examples of the material for the outsole member 14 include PU (polyurethane), PVC (polyvinyl chloride), and EVA (ethylene vinyl acetate). It is desirable to use a highly durable material for the outsole member 14. The material for the outsole member 14 may be the same as that for the midsole member 15, or may be a different material.

[0035] According to the geta 10 of the first embodiment, the impact on the heel when walking can be reduced, and an unprecedentedly comfortable fit can be achieved.

[0036] That is, in this embodiment, the hollow member 16 is provided at least at a position corresponding to the heel part inside the midsole member 15 of the base 11 of the geta 10, and the thickness B of the hollow member 16 is set to be sufficiently large relative to the thickness A of the entire base 11 at the position corresponding to the heel part (the ratio of B / A is set to 0.2 or more), so that the impact on the heel during walking can be reduced compared to conventional geta (without the hollow member 16), and a comfortable fit that has never been seen before can be realized. In this case, the thickness B of the hollow member 16 relative to the thickness A of the entire base 11 is not set excessively large (the ratio of B / A is set to 0.7 or less), so that the thickness of the top plate 13 and the outsole member 14 can be sufficiently secured. By securing the sufficient thickness of the top plate 13, it is possible to avoid impairing the comfort of the geta 10, and by securing the sufficient thickness of the outsole member 14, it is possible to avoid impairing the durability of the geta 10.

[0037] Furthermore, in this embodiment, the width D of the hollow member 16 relative to the width C of the entire base 11 at the position corresponding to the heel is set sufficiently large (the ratio D / C is set to 0.8 or more), thereby reducing the impact on the heel when walking and achieving an unprecedented comfortable fit.

[0038] In addition, in this embodiment, since the hollow member 16 is provided rearward of the position of the rear hole 17, it is possible to reduce the impact on the heel when walking, thereby achieving an unprecedented comfortable fit.

[0039] In addition, in this embodiment, the sandals 10 are configured symmetrically, so by wearing the sandals 10 alternately on the left and right, the wear on the outside and inside of the outsole member 14 of the sandals 10 becomes even, and the sandals 10 can be worn for a long time. In this case, the hollow member 16 is also configured symmetrically, so the sandals 10 can be worn comfortably the same whether worn on the left or right side.

[0040] In addition, in this embodiment, the midsole member 15 is made of synthetic resin and manufactured by insert molding with the hollow member 16 as an insert item, making it possible to easily manufacture the midsole member 15 having the hollow member 16 provided therein.

[0041] (Second embodiment) Next, the second embodiment of the setta of the present invention will be explained. Here, the difference between the second embodiment and the first embodiment will be mainly explained. Unless otherwise specified, the configuration and operation of this embodiment are the same as the first embodiment.

[0042] Fig. 6 is a side view showing the geta of this embodiment, and Fig. 7 is a plan view showing the geta of this embodiment. Also, Fig. 8 is an exploded side view of the geta of this embodiment. As shown in Fig. 6 to Fig. 8, the geta 20 is composed of a base 21 and a strap 22, and the base 21 has a top plate 23 to which the strap 22 is attached, and a sole member 24 as a bottom plate.

[0043] A hollow member 26 is provided inside the sole member 24 at a position corresponding to at least the heel portion (see also FIGS. 9 and 10). Here, "the hollow member 26 is provided inside the sole member 24" means that most of the hollow member 26 is provided inside the sole member 24, and a part of the hollow member 26 may be exposed to the outside of the sole member 24.

[0044] As shown in FIG. 9, the ratio B / A of the thickness B of the hollow member 26 to the thickness A of the base 21 at the position corresponding to the heel is set to 0.2 or more and 0.7 or less, more preferably 0.3 or more and 0.6 or less. As shown in FIG. 10, the ratio D / C of the width D of the hollow member 26 to the width C of the base 21 at the position corresponding to the heel is set to 0.8 or more, more preferably 0.9 or more. In the example of FIG. 9, the ratio B / A of the thickness B of the hollow member 26 to the thickness A of the base 21 is 0.357, and in the example of FIG. 10, the ratio D / C of the width D of the hollow member 26 to the width C of the base 21 is 0.976. Here, the thickness B of the hollow member 26 refers to the maximum value of the thickness of the hollow member 26. For example, when the thickness differs depending on the part of the hollow member 26, the thickness value of the part with the greatest thickness among the parts of the hollow member 26 corresponds to the thickness value.

[0045] As shown in Fig. 10, the hollow member 26 is provided behind (to the heel side; right side in Fig. 10) the position P of the rear hole 27 through which the cross strap of the thong 22 passes. As shown in Fig. 7, the setta 20 is configured symmetrically in a plan view with the center line L of the setta 20 as an axis, and as shown in Fig. 10, the hollow member 26 is configured symmetrically in a plan view with the center line Ls of the sole member 24 as an axis. In this embodiment, the center line L of the setta 20 and the center line Ls of the sole member 24 coincide in a plan view.

[0046] The sole member 24 is made of synthetic resin, and is manufactured by insert molding using the hollow member 26 as an insert, thereby providing the hollow member 26 inside the sole member 24. Examples of materials that can be used for the sole member 24 include PU (polyurethane), PVC (polyvinyl chloride), and EVA (ethylene vinyl acetate).

[0047] The geta 20 of the second embodiment as described above also provides the same effects as those of the first embodiment.

[0048] In this embodiment, the hollow member 26 is provided at a position corresponding to at least the heel part inside the sole member 24 of the base 21 of the geta 20, and the thickness B of the hollow member 26 is set sufficiently large relative to the thickness A of the entire base 21 at the position corresponding to the heel part (the ratio of B / A is set to 0.2 or more), so that the impact on the heel during walking can be reduced compared to conventional geta (without the hollow member 26), and a comfortable fit that has never been seen before can be realized. In this case, the thickness B of the hollow member 26 relative to the thickness A of the entire base 21 is not set excessively large (the ratio of B / A is set to 0.7 or less), so that the thickness of the top plate 23 and the sole member 24 can be sufficiently secured. By securing the sufficient thickness of the top plate 23, it is possible to avoid impairing the comfort of wearing the geta 20, and by securing the sufficient thickness of the sole member 24, it is possible to avoid impairing the durability of the geta 20.

[0049] Furthermore, in this embodiment, the width D of the hollow member 26 relative to the width C of the entire base 21 at the position corresponding to the heel is set to be sufficiently large (the ratio D / C is set to 0.8 or more), thereby reducing the impact on the heel when walking and achieving an unprecedentedly comfortable fit.

[0050] In addition, in this embodiment, by providing the hollow member 26 rearward of the position of the rear hole 27, it is possible to reduce the impact on the heel when walking, thereby achieving an unprecedentedly comfortable fit.

[0051] In addition, in this embodiment, the sandals 20 are configured symmetrically, so by wearing the sandals 20 alternately on the left and right, the wear on the outside and inside of the sole member 24 of the sandals 20 becomes even, allowing the sandals 20 to be worn for a long time. In this case, the hollow member 26 is also configured symmetrically, so the same wearing comfort can be obtained whether the sandals 20 are worn on the left or right side.

[0052] In addition, in this embodiment, the sole member 24 is made of synthetic resin and manufactured by insert molding with the hollow member 26 as an insert item, making it possible to easily manufacture the sole member 24 with the hollow member 26 provided inside.

[0053] Although the embodiments of the present invention have been described above by way of example, the scope of the present invention is not limited to these, and changes and modifications can be made according to the purpose within the scope of the claims. [Industrial Applicability]

[0054] As described above, the geta sandals of the present invention have the effect of reducing the impact on the heels when walking and providing an unprecedented level of comfort, making them useful as footwear. [Explanation of symbols]
