Description

【Technical Field】 【0001】 The present invention relates to shoes and counters, and particularly to shoes and counters that prevent the heels from lifting and slipping off during wear, making them easy to put on without shoehorns. 【Background Art】 【0002】 There are shoes that can be put on without using hands and without a shoehorn (see, for example, Patent Document 1). This low shoe (11a) has a heel part (14) at the rear end. At the upper end of the heel part (14), a rigid protruding piece part (16) extending obliquely upward and backward is formed. The protruding piece part (16) has a core of a shank core extension part (17b) extending from a shank core (17) provided in the heel part (14) to obtain hardness. The tip height of the protruding piece part (16) is made higher than the front end height of the opening edge (15). Further, the protruding piece part (16) has a curved shape with the inner surface side being concave in the cross-sectional shape, and the contour shape of the tip (16a) of the protruding piece part (16) is made round to increase the strength and soften the contact with the heel. 【Prior Art Documents】 【Patent Documents】 【0003】 [[ID=2�]] 【Patent Document 1】 Japanese Patent Application Laid-Open No. 2022-139151 【Summary of the Invention】 【Problems to be Solved by the Invention】 【0004】 In the above-mentioned low shoe, there is a clearance between the low shoe and the foot so that the low shoe can be put on while the heel of the foot abuts against the inside of the protruding piece part (16) and the opening edge is widened on the instep and both sides of the instep. Therefore, there is a problem that the heel floats and the heel slips off during wear due to the clearance between the low shoe and the foot. 【0005】 An object of the present invention is to provide shoes and counters in consideration of the above problems. [Means for solving the problem] 【0006】 The shoe according to claim 1 is a shoe having a counter built into the heel, wherein, when viewed from the rear, the built-in counter has a central opening in the center of the counter, on the side closer to the upper end of the counter than the lower end of the counter, a right-side longitudinal opening communicating with the central opening on the right side of the counter, and a left-side longitudinal opening communicating with the central opening on the left side of the counter, wherein the right-side longitudinal opening slopes downward as it moves away from the central opening in the longitudinal direction of the right-side longitudinal opening, and the left-side longitudinal opening slopes downward as it moves away from the central opening in the longitudinal direction of the left-side longitudinal opening. 【0007】 Furthermore, the shoe according to claim 2 is the shoe according to claim 1, wherein when the shoe is worn, the weight causes the portion of the counter above the central opening to come into contact with the portion of the counter below the central opening, and the portion of the counter above the right side longitudinal opening and the portion of the counter above the left side longitudinal opening move outwards, respectively. 【0008】 Furthermore, the shoe according to claim 3 is the shoe according to claim 1, wherein one of the opposing surfaces of the central opening is the upper end surface, and the other opposing surface of the central opening is the lower end surface, and in a side view of the counter, the vertical dimension M from the lower end of the counter to the lower end surface is greater than the opposing distance m between the upper end surface and the lower end surface (M>m), and when putting on the shoe, the weight causes the upper end surface, which is the part of the counter above the central opening, to come into contact with the lower end surface, which is the part of the counter below the central opening, and the lower end surface acts as a stopper. 【0009】 Furthermore, the shoe according to claim 4 is the shoe according to claim 1, wherein, in a side view, the length L of the lower end of the counter is greater than the maximum height H of the counter, and the right and left sides of the counter extend to the sides of the wearer's midfoot. 【0010】 Furthermore, the counter described in claim 5 is a counter located in the heel of a shoe, and when viewed from the rear, on the side closer to the upper end of the counter than the lower end of the counter, it has a central opening in the center of the counter, a right-side longitudinal opening communicating with the central opening on the right side of the counter, and a left-side longitudinal opening communicating with the central opening on the left side of the counter, wherein the right-side longitudinal opening slopes downward as it moves away from the central opening in the longitudinal direction of the right-side longitudinal opening, and the left-side longitudinal opening slopes downward as it moves away from the central opening in the longitudinal direction of the left-side longitudinal opening. [Effects of the Invention] 【0011】 According to the shoe described in claim 1, the shoe has a counter built into the heel, and when viewed from the back, the built-in counter has a central opening in the center of the counter, a right-side longitudinal opening communicating with the central opening on the right side of the counter, and a left-side longitudinal opening communicating with the central opening on the left side of the counter, the right-side longitudinal opening slopes downward as it moves away from the central opening in the longitudinal direction, and the left-side longitudinal opening slopes downward as it moves away from the central opening in the longitudinal direction, so when a load (for example, the weight of the foot applied via the heel) is applied to the side of the counter closer to the upper end than the lower end, the portion of the counter located above the central opening, the right-side longitudinal opening, and the left-side longitudinal opening moves downward, widening the opening (see Figure 7(a) → Figure 7(b)). (See Figure 11 → Figure 12) This makes the shoes easier to put on, and after putting them on, the counter returns to its original position, and the heel part of the shoe conforms to the heel of the foot via the counter, preventing heel lifting and the shoes from slipping out while worn. 【0012】 Furthermore, according to the shoe described in claim 2, in addition to the effects of the invention described in claim 1 above, when putting on the shoe, the weight causes the upper part of the counter above the central opening to come into contact with the lower part of the counter above the central opening, acting as a stopper. This causes the upper part of the counter above the right side longitudinal opening and the upper part of the counter above the left side longitudinal opening to move outward, widening the opening and making it easier to put on the shoe. 【0013】 Furthermore, according to the shoe described in claim 3, in addition to the effects of the invention described in claim 1 above, when the shoe is worn, the upper end surface, which is the part of the counter above the central opening, comes into contact with the lower end surface, which is the part of the counter below the central opening, due to the wearer's weight, and the lower end surface acts as a stopper. Therefore, by adjusting M and m, the amount of downward movement can be appropriately adjusted, and when the shoe is worn, the upper end surface, which is the part of the counter above the central opening, comes into contact with the lower end surface, which is the part of the counter below the central opening. The part of the counter below the central opening comes into contact with the part of the counter above the right side longitudinal opening and the part of the counter above the left side longitudinal opening, respectively, which moves to expand outwards. As a result, the opening becomes wider and easier to put on. Moreover, after putting on the shoes, the parts of the counter above the central opening, the right side longitudinal opening and the left side longitudinal opening return to their original positions, so that the heel part of the shoe conforms to the heel of the foot via the counter, preventing heel lifting and heel slippage during wear. 【0014】 Furthermore, according to the shoe described in claim 4, in addition to the effects of the invention described in claim 1 above, when a load (for example, the weight of the foot applied via the heel) is applied to the side of the counter closer to the upper end than the lower end of the counter, the portion of the counter located above the central opening, the longitudinal opening on the right side, and the longitudinal opening on the left side moves downward, widening the opening (see Figure 7(a) → Figure 7(b), Figure 11 → Figure 12) to make it easier to put on the shoe. Moreover, after putting on the shoe, the portion of the counter returns to its original position, and in a side view, the length L of the lower end of the counter is greater than the maximum height H of the counter, and the right and left sides of the counter extend to the sides of the wearer's midfoot, so that the heel portion of the shoe conforms to the heel of the foot via the counter, and grips the heel to enhance hold, preventing heel lifting, heel slippage, etc., when wearing the shoe. 【0015】 Furthermore, according to the counter described in claim 5, when the counter is viewed from the rear, on the side closer to the upper end of the counter than the lower end of the counter, there is a central opening in the center of the counter, a right-side longitudinal opening communicating with the central opening on the right side of the counter, and a left-side longitudinal opening communicating with the central opening on the left side of the counter, the right-side longitudinal opening inclins downward as it moves away from the central opening in the longitudinal direction of the right-side longitudinal opening, and the left-side longitudinal opening is from the central opening Because the left-side longitudinal opening slopes downward as it moves away from the longitudinal direction, when a load (for example, the weight of the foot applied via the heel) is applied to the side of the counter closer to the upper end than the lower end, the parts of the counter located above the central opening, the right-side longitudinal opening, and the left-side longitudinal opening move downward, widening the opening and making it easier to put on (making it easy to put on without the heel protruding and without a shoehorn). Moreover, because the counter itself does not soften, it has the effect of making it difficult for the foot to slip out of the shoe.

[Figure 11] FIG. 11 is a photograph taken of the shoe of the embodiment of FIG. 1 without applying a load to the heel portion. [Figure 12] FIG. 12 is a photograph taken of the shoe of the embodiment of FIG. 1 with a load applied to the heel portion and the vicinity of the heel bulging outward. 【MODE FOR CARRYING OUT THE INVENTION】 【0017】 The shoe and counter according to an embodiment of the present invention will be described with reference to the drawings (FIGS. 1 to 12). As shown in Figure 1, S is a shoe with a counter C built into the heel. When viewed from the rear, the built-in counter C has a central opening 10 in the center of the counter C, on the side closer to the upper end C2 of the counter C than to the lower end C1 of the counter C, a right-side longitudinal opening 11 communicating with the central opening 10, and a left-side longitudinal opening 12 communicating with the central opening 10 and on the left side of the counter C. 【0018】 The right-side longitudinal opening 11 slopes downward as it moves away from the central opening 10 in the longitudinal direction, and the left-side longitudinal opening 12 slopes downward as it moves away from the central opening 10 in the longitudinal direction. In Figure 6, 1 is the counter body, and the counter body 1 is made of a material such as nylon or polypropylene. The counter body 1 is embedded in the shoe S with an outer member 2 and an inner member 3, with a cushion member 4 in between (Figures 2 and 10). 【0019】 Therefore, according to the shoe S described above, the shoe S has a counter C built into the heel, and when viewed from the back of the built-in counter C, on the side closer to the upper end C2 of the counter C than to the lower end C1 of the counter C, there is a central opening 10 in the center of the counter C, and a right-side longitudinal opening 11 communicating with the central opening 10 on the right side of the counter C, and a left-side longitudinal opening 12 communicating with the central opening 10 on the left side of the counter C, the right-side longitudinal opening 11 is inclined downward as it moves away from the central opening 10 in the longitudinal direction of the right-side longitudinal opening 11, and the left-side longitudinal opening 12 is inclined as it moves away from the central opening 10 in the longitudinal direction of the left-side longitudinal opening 12 As the counter C slopes downward, without enlarging the heel portion of the shoe S, when a load (for example, weight applied via the heel of the foot) is applied to the side of the counter C closer to the upper end C2 than the lower end C1 of the counter C, part C3 of the counter C located above the central opening 10, the right side longitudinal opening 11, and the left side longitudinal opening 12 of the counter C moves downward, widening the opening and making it easier to put on (making it easy to put on without a shoehorn, without the heel portion protruding). Moreover, after putting on the shoe S, the part of the counter C returns to its original position, and the heel portion of the shoe S conforms to the heel of the foot via the counter C, which has the effect of preventing heel lifting, heel slippage, etc. when wearing the shoe. 【0020】 Looking at the counter C alone, as described above, when viewed from the back, on the side closer to the upper end C2 of the counter C than the lower end C1 of the counter C, there is a central opening 10 in the center of the counter C, and communicating with this central opening 10, there is a right-side longitudinal opening 11 on the right side of the counter C, and communicating with the central opening 10, there is a left-side longitudinal opening 12 on the left side of the counter C, the right-side longitudinal opening 11 is inclined downward as it moves away from the central opening 10 in the longitudinal direction of the right-side longitudinal opening 11, and the left-side longitudinal opening Since the opening 12 slopes downward as it moves away from the central opening 10 in the longitudinal direction of the left side longitudinal opening 12, when a load (for example, the weight of the foot applied via the heel) is applied to the side of the counter C built into the shoe S that is closer to the upper end C2 of the counter C than to the lower end C1 of the counter C, the part of the counter C C located above the central opening 10, the right side longitudinal opening 11, and the left side longitudinal opening 12 moves downward, widening the opening and making it easier to put on (having effects such as making it easier to put on without the heel protruding and without a shoehorn). 【0021】 To elaborate further, when wearing the shoe S, the weight causes the upper part of the counter C above the central opening 10 to come into contact with the lower part of the counter C above the central opening 10 [see Figure 7(b)], and the upper part of the counter C above the right side longitudinal opening 11 and the upper part of the counter C above the left side longitudinal opening 12 move outwards [see Figure 8(b)]. Therefore, the opening becomes wider and easier to put on, and after putting on the shoe S, the counter C above the central opening 10, the long-shaped opening on the right side 11, and the long-shaped opening on the left side 12 returns to its original position, so that the heel part of the shoe S conforms to the heel of the foot via the counter C, preventing the heel from lifting or slipping out when worn. 【0022】 Furthermore, in a side view of counter C, the vertical dimension M from the lower end of counter C to the lower end surface M1 is greater than the opposing distance m between the upper end surface m1 and the lower end surface M1 (M>m). When putting on shoes, the weight causes the upper end surface m1, which is the part of counter C above the central opening 10, to contact the lower end surface M1, which is the part of counter C below the central opening 10, and the lower end surface M1 acts as a stopper. Therefore, by adjusting M and m, the amount of downward movement can be adjusted as appropriate. When putting on shoes S, the weight causes the part of counter C above the central opening 10 to contact the lower end surface M1 of the central opening 10. When the counter C part comes into contact with the right side longitudinal opening 11 and the left side longitudinal opening 12, the counter C part above the right side longitudinal opening moves outward, making the opening wider and easier to put on. Furthermore, after putting on the shoe S, the counter C parts above the central opening 10, the right side longitudinal opening 11, and the left side longitudinal opening 12 return to their original positions, so the heel part of the shoe S conforms to the heel of the foot via the counter C, preventing heel lifting and the shoe slipping out while worn. Furthermore, as shown in the side view, Figures 2 and 4, the lower end length L of the counter C is greater than the maximum height H of the counter C, and the right and left sides of the counter C extend to the sides of the wearer's midfoot. Therefore, when a load (for example, the weight of the foot applied via the heel) is applied to the side of the counter closer to the upper end than the lower end, the parts of the counter located above the central opening, the longitudinal opening on the right side, and the longitudinal opening on the left side move downward, widening the opening (see Figure 7(a) → Figure 7(b), Figure 11 → Figure 12) to make it easier to put on the shoes. Moreover, after putting on the shoes, the parts of the counter return to their original position, and in a side view, the length L of the lower end of the counter is greater than the maximum height H of the counter, and the right and left sides of the counter extend to the sides of the wearer's midfoot. As a result, the heel part of the shoe conforms to the heel of the foot via the counter, and also grips and holds the foot, preventing heel lifting and heel slippage during wear.
