Description

  The present invention relates to a shoe having a heel counter on the heel portion of the upper (cover) of the shoe, and in particular, an improvement in the structure of the heel counter for improving the holdability of the upper part of the ribs of the foot during exercise. About.

  In order to prevent lateral movement of the heel portion of the foot when landing, a shoe having a heel counter on the heel portion of the shoe is provided in order to ensure the shape retention of the heel portion of the shoe.

  Most heel counters that have been widely used in the past are cup-shaped so as to wrap around the heel of the foot. However, as shown in JP-A-64-8903 and JP-A-64-8904. Various shapes have also been proposed.

  The heel counter described in FIGS. 6 and 7 of Japanese Patent Application Laid-Open No. 64-8903 is provided with a heel counter body disposed on the heel portion of the shoe and an upper portion extending forward along the shoe mouth. It is composed of an ankle support section. Further, the heel counter described in FIGS. 10 and 11 of JP-A-64-8904 is a heel counter body disposed on a heel portion of a shoe and a front portion thereof along the shoe mouth of the shoe at the upper portion thereof. And an arch supporter extending forward along the sole of the shoe at the lower part of the heel counter body.

Here, the ankle support portion (or ankle supporter) in the heel counter described in each of the above-mentioned publications captures the ankle more reliably and increases the stability of the ankle portion during movement (that is, around the talus of the foot). A member (see JP-A 64-8903, page 3, lower left column, lines 9 to 10 and JP-A 64-8904, page 3, lower right column, lines 15 to 17) It is not configured to enhance the holdability of the upper ribs of the foot (especially during landing).
Japanese Patent Laid-Open No. 64-8903 (see FIGS. 6 and 7) Japanese Unexamined Patent Publication No. 64-8904 (see FIGS. 10 and 11)

  The present invention has been made in view of such circumstances, and the problem to be solved by the present invention is a shoe provided with a heel counter that can improve the holdability of the upper ribs of the foot during exercise. Is to provide.

  In the shoe according to the first aspect of the present invention, the heel counter provided in the upper heel part is disposed around the lower rib part at a position corresponding to the lower part of the rib of the shoe wearer's foot, and is outside the shoe. A lower support portion that extends substantially in the front-rear direction on the instep side and the instep side, and is disposed around the upper rib portion at a position corresponding to the upper portion of the rib of the foot of the shoe wearer, and on the outer side of the shoe And an upper support portion that extends substantially in the longitudinal direction on the inner shell side, a connecting portion that connects the lower support portion and the upper support portion in the vertical direction, and a lower support portion and the upper support portion that are separated in the vertical direction. As described above, it is formed between a lower support portion and an upper support portion, and a bottom portion thereof is formed with a notch extending to the connecting portion.

  According to the first aspect of the present invention, the lower rib portion of the foot of the shoe wearer is held by the lower support portion of the heel counter that is disposed around the lower rib portion and extends in the front-rear direction. It is held by an upper support portion of a heel counter disposed around the upper portion of the bone and extending in the front-rear direction. This upper support part improves the holdability of the upper part of the ribs of the foot during exercise, and thereby, it is possible to reliably control the lateral shaking of the heel of the foot that occurs during exercise, particularly immediately after landing.

  On the other hand, in the conventional cup-shaped heel counter, since the upper support part extending in the front-rear direction along the upper part of the rib is not provided, the holdability with respect to the upper part of the rib is poor. Further, the heel counter shown in the above-mentioned Japanese Patent Application Laid-Open Nos. 64-8903 and 64-8904 is provided with an ankle support portion (or ankle supporter) extending in the front-rear direction along the circumference of the ankle. This is intended to hold the ankle (ie, around the talus located above the ribs of the foot). And in the heel counter shown to said gazette, the shape from a rib lower part to a rib upper part has a shape similar to the conventional cup-shaped heel counter. Therefore, in each of the above publications, like the conventional cup-shaped heel counter, the holdability with respect to the upper part of the rib is poor.

  Moreover, in the invention of claim 1, since the notch extending to the connecting portion of the upper and lower part support parts while separating the upper and lower part support parts in the vertical direction is formed between the upper and lower part support parts, the shoe landing especially during exercise. When the upper lower portion of the shoe is about to deform along with the deformation of the sole immediately afterward, it is possible to prevent the deformation of the upper lower portion from propagating upward while being blocked by the notch of the heel counter. As a result, it is possible to prevent the upper support portion of the heel counter from being deformed outward due to the deformation of the lower portion of the upper part, thereby allowing the upper support portion to be in close contact with the upper portion of the ribs at all times. Can prevent the lateral movement of the ribs and improve the holdability of the upper ribs during exercise. In this way, it is possible to more reliably regulate the lateral movement of the heel of the foot that occurs during landing.

  As described in the invention of claim 2, the connecting portion that connects the upper and lower support portions may be arranged at the rear end of the shoe to constitute a heel counter body portion.

  In this case, since the heel counter main body is disposed from the lower part to the upper part of the rear end of the radius, the fit to the rear end of the radius can be improved.

In the invention of claim 3, when the length L _n in the front-rear direction from the rear end of the shoe heel to the bottom of the notch of the heel counter body is L as the display size foot length of the shoe, L _n <0.17 × L Is set to

  Here, the position where the distance from the rear end of the shoe heel is 0.17L coincides with the position of the load center line of the rib (the line of action of the wearer's load at the time of ground contact). That is, at the time of ground contact, it can be considered that the full load is applied at a position of 0.17 L from the rear end of the shoe heel. Therefore, when the wearer lands from the sole heel rear end of the shoe, the load acts on the load center line with the sole heel rear end as a fulcrum, so that the sole is deformed at the load center line portion. Along with the deformation, the lower part of the upper tends to deform at the load center line.

  At this time, the position of the notch bottom portion of the heel counter (that is, the front end portion of the heel counter main body portion) is arranged on the rear side from the position at a distance of 0.17 L from the rear end of the shoe heel, in other words, Since the load center line passes through the notch, it is possible to prevent the deformation of the upper lower part due to the load acting on the load center line of the rib from propagating through the heel counter main body part to the upper support part of the heel counter. . In other words, the deformation of the lower part of the upper due to the load acting on the load center line of the rib can be surely released by the notch of the heel counter.

  On the other hand, the position of the notch bottom portion is arranged on the front side of the position at a distance of 0.17 L from the rear end of the shoe heel (that is, the load center line of the rib passes through the heel counter main body). In this case, the deformation of the upper due to the load acting on the ribs easily propagates to the upper support portion via the heel counter main body portion.

  The connecting portion that connects the upper and lower support portions may be disposed at an intermediate position in the front-rear direction of the lower support portion and the upper support portion, as described in the invention of claim 4.

  In this case, since a gap is formed between the upper and lower support portions on the rear side of the connecting portion, the heel counter can be reduced in weight.

  In the invention of claim 5, the height position of the upper edge of the upper support portion at the rear end of the shoe is disposed below the mouth of the shoe upper. In this case, it is possible to prevent the upper support portion of the heel counter from hindering the flexibility of the upper mouth of the shoe.

  The height position of the notch bottom portion of the heel counter coincides with the height position of the rearmost projecting end of the rear upper end of the shoe as described in the invention of claim 6.

  In this case, the height position of the notch bottom portion can be made to coincide with the height position of the most projecting end to the rear of the rib, thereby effectively supporting the movement of the upper and lower portions of the rib. It becomes like this.

In the invention of claim 7, the length L ₁ in the front-rear direction from the rear end of the shoe heel of the lower support portion is set to L _l > 0.17 × L, where L is the display size foot length of the shoe. Yes.

  Here, as described above, the position where the distance from the rear end of the shoe heel is 0.17L coincides with the position of the load center line of the ribs (the line of action of the load of the wearer at the time of ground contact). Therefore, by disposing the front end of the lower support portion forward of the position at a distance of 0.17 L from the rear end of the shoe heel (in other words, allowing the load center line of the rib to pass through the lower support portion). The deformation of the upper due to the load acting on the ribs can be effectively regulated by the lower support part.

In the invention of claim 8, the length L _u in the front-rear direction from the rear end of the shoe heel of the upper support portion is set such that L _u > 0.17 × L, where L is the display size foot length of the shoe. Yes.

  In this case, since the tip of the upper support part is arranged on the front side of the position at a distance of 0.17 L from the rear end of the shoe heel (in other words, the load center line of the rib passes through the upper support part). Upper deformation due to the load acting on the load center line of the ribs can be effectively controlled by the upper support part. This makes it possible to hold the upper rib part of the foot by the upper support part during exercise, especially during landing. Can be improved.

  In the invention of claim 9, the upper support portion extends to the instep portion of the upper of the shoe, and an eyelet hole for shoelace insertion is provided at the tip thereof.

  In this case, by tightening the shoelace, the upper support part can be brought into close contact with the upper part of the rib, and this can further improve the holdability of the upper part of the rib of the foot during exercise, particularly during landing. As a result, it is possible to more reliably regulate the lateral movement of the foot buttocks that occurs during landing.

In the invention of claim 10, the length L _u in the front-rear direction from the rear end of the shoe heel of the upper support portion is different between the inner side and the outer side of the shoe.

  In this case, for example, when preventing the rotation of the foot, the length of the upper support portion in the front-rear direction should be increased on the outer side of the shoe, and also when preventing the rotation of the foot In this case, the length of the upper support portion in the front-rear direction may be increased on the inner side of the shoe. Thereby, it becomes possible to provide shoes according to individual differences among competition events or shoe wearers.

  In the invention of claim 11, the rigidity of the upper support part is higher than the rigidity of the lower support part.

  In this case, since the upper support portion is less likely to be deformed, it is possible to further improve the holdability of the upper portion of the rib by the upper support portion, and to more reliably regulate the lateral shake of the foot heel portion that occurs at the time of landing. .

  As a method of making the rigidity of the upper support portion higher than the rigidity of the lower support portion, as in the invention of claim 12, a rib is provided on the upper support portion, or the thickness of the upper support portion is made to be lower than that of the lower support portion. It is thicker than the wall thickness, the upper support part is made of a material different from the lower support part (high rigidity material), the upper support part is made of an anisotropic material, and the upper support part is made of fiber reinforced plastic. It is conceivable to configure or make the upper support part harder than the lower support part.

  Further, as in the invention of claim 13, deformation (that is, opening) of the upper support portion to the outside of the shoe may be suppressed by providing a reinforcing material on the upper of the shoe.

  As described above, according to the present invention, since the heel counter is provided with the upper support portion disposed around the upper portion of the rib of the foot and extending in the front-rear direction, the holdability of the upper portion of the rib of the foot during exercise is improved. In particular, the lateral movement of the heel of the foot that occurs during landing can be reliably controlled. Moreover, according to the present invention, the notch extending between the upper and lower support portions is formed between the upper and lower support portions while separating the upper and lower support portions in the vertical direction. When the upper of the shoe is about to be deformed, the deformation of the lower part of the upper can be prevented from propagating upward while being blocked by the notch of the heel counter. As a result, it is possible to prevent the upper support portion of the heel counter from being deformed outward due to the deformation of the upper, thereby further improving the holdability of the upper portion of the ribs during exercise and the foot heel generated at the time of landing This makes it possible to more reliably regulate the horizontal movement of the part.

Embodiments of the present invention will be described below with reference to the accompanying drawings.
<First embodiment>

The bottom portion 14 a is constituted by a notch 14 extending to the connecting portion 13. 1, reference numeral T _A indicates the foot of the talus.

  Although not shown in FIG. 1, the upper and lower support portions 11 and 12 are also provided on the outer side of the shoe 1, and extend substantially in the front-rear direction on the outer side as well. In this embodiment, the upper and lower support portions 11 and 12 disposed on the outer side are arranged symmetrically with the upper and lower support portions 11 and 12 on the inner side, and the upper and lower support portions 11 and 12 The length in the front-rear direction is equal on the inner side and the outer side of the upper 3.

In FIG. 1, a point C _A1 indicates the rearward most protruding point of the rib C _A , and in the claims and the specification of the present application, the upper part and the lower part are respectively _separated from the point C _A1. to be defined as upper and lower calcaneus C _a.

In this example, the connecting portion 13 is disposed at the heel rear end portion 30 of the upper 3 of the shoe 1 to constitute a heel counter main body portion. The upper and lower support parts 11 and 12 extend forward from the upper and lower positions of the heel counter main body part 13, respectively. The bottom 14 a of the notch 14 extends to the heel counter main body 13. Further, the height position of the bottom portion 14a of the notch 14 coincides with the height position of the point C _A1 which is the most rearward protruding point of the rib C _A , and the point C _A1 is the rear end of the upper 3 It coincides with the height position of the point 30a which is the most protruding point. Therefore, the bottom 14a of the notch 14 coincides with the height position of the point 30a.

As shown in FIG. 2, the length in the front-rear direction from the most protruding point 30 a at the rear end of the upper 3 to the notch bottom 14 a of the heel counter main body 13 (that is, the length in the front-rear direction of the heel counter main body 13) L _n When the display size foot length of shoes is L,
L _n <0.17 × L
Is set to

Here, in FIG. 2, line G in the vertical direction, from the most salient points 30a of the heel rear end of the upper 3 shows the distance 0.17 × L, which is the load center line of the heel bone C _A ( That is, it corresponds to the load action line that can be considered that the wearer's full load is acting at the time of grounding. Therefore, the inequality, notch root portion 14a is disposed behind the load center line G of the calcaneus C _A, in other words, the load center line G of the calcaneus C _A is passed through the notch 14, It expresses that.

The length L ₁ in the front-rear direction from the most protruding point 30a at the rear end of the upper 3 to the tip of the lower support portion 11 is L when the display size foot length of the shoe is L.
L _l > 0.17 × L
Is set to

The above inequality, the lower support portion 11 distal end is disposed in front of the load center line of the calcaneus C _A, in other words, the load center line of the calcaneus C _A is through the lower support portion 11, that It represents.

The length L _u in the front-rear direction from the most protruding point 30a at the rear end of the upper 3 to the tip of the upper support portion 12 is L when the display size foot length of the shoe is L.
L _u > 0.17 × L
Is set to

The above inequality, the upper support portion 12 distal end is positioned in front of the load center line of the calcaneus C _A, in other words, the load center line of the calcaneus C _A is through the upper support portion 12, that It represents.

  The height position of the upper edge 12 a of the upper support portion 12 at the rear end of the upper 3 of the shoe 1 is disposed below the mouth 31 of the upper 3 of the shoe 1. Further, the height position of the upper edge 12 a of the upper support portion 12 at the rear end of the upper 3 is disposed above 70% of the height H of the upper rear end portion of the upper 3.

That is, when the point at the back end of the upper edge 12a is 12e, the height from the upper lower end of the point 12e is h, and the height from the upper lower end of the upper end of the upper heel of the upper 3 is H,
0.7 × H <h <H
Is set to

Here, the height position of (0.7 × H) from the upper lower end is calculated using a so-called “folding formula” that defines a method for calculating the dimensions of each part of the shoe. It corresponds to the upper end position of the calcaneus C _a.

Further, the height position of the most protruding point 30a at the rear end of the upper 3 corresponds to the height position of (0.4 × H) from the lower end of the upper. ”. That is, when the height from the upper lower end of the most protruding point 30a is h _n ,
h _n = 0.4H
Is set to

  The heel counter 10 is made of, for example, a thermoplastic polyurethane (TPU), a polyamide elastomer (PAE), a thermoplastic resin such as an ABS resin, or a thermosetting resin such as an epoxy resin or an unsaturated polyester resin.

Next, the function and effect of this embodiment will be described.
According to shoe 1 made to the above configuration, calcaneus C _A lower portion of the foot of the shoe wearer P is held by the lower support portion 11 of the heel counter 10 extending in the front-rear direction is disposed around the calcaneus C _A lower is, calcaneus C _a top is held by the upper support portion 12 of the heel counter 10 extending in the front-rear direction is disposed around the calcaneus C _a top. The upper support portion 12 improves the hold with respect to the heel bone C _A top of the foot during exercise, thereby, becomes a horizontal blur of the heel portion of the foot that occur during exercise when particular landing can be reliably restricted. Further, it is possible to improve the fit against the heel bone C _A rear end of the foot of the shoe wearer P by the heel counter body portion 13.

Moreover, since the notch 14 extended to the heel counter main-body part 13 of the upper and lower part support parts 11 and 12 is formed between the upper and lower part support parts 11 and 12, separating the upper and lower part support parts 11 and 12 in the vertical direction, When the lower part of the upper 3 of the shoe 1 is going to be deformed due to the deformation of the sole 2 immediately after landing of the shoe during exercise, the notch 14 of the heel counter 10 propagates the deformation of the lower part of the upper 3 upward. It can be suppressed while blocking. As a result, the upper support portion 12 of the heel counter 10 is prevented from being deformed outward under the influence of the upper third lower deformation, thereby, it is adhered to the upper support portion 12 to the upper portion of the constantly calcaneus C _A can be, to prevent the deflection side of the heel bone during pronation, the calcaneus C _a top hold at the time of exercise can be further improved. In this way, it is possible to more reliably regulate the lateral movement of the heel of the foot that occurs during landing.

Moreover, the length in the front-rear direction (ie, the length in the front-rear direction of the heel counter body 13) L _n from the most protruding point 30a at the rear end of the upper 3 to the notch bottom 14a of the heel counter body 13 is L _n < 0.17 × are set L, and calcaneus C load center line G is the depth of the notch 14 so as to pass through the notch 14 of _a at touchdown is set.

In this case, when the wearer P lands from the sole heel rear end of the shoe 1, the load acts on the load center line G with the sole heel rear end as a fulcrum. deformed portion, tries to lower the deformation of the upper 3 at the portion of the load center line G in accordance with the deformation of the sole 2, through this time, the load center line G of the calcaneus C _a is a notch 14 for that, the upper third lower deformation due to the load acting on the load center line G of the calcaneus C _a is, to propagate to the upper support portion 12 of the heel counter 10 through the heel counter body portion 13 can be prevented. In other words, the load upper third lower deformation by acting on the load center line G of the calcaneus C _A, it is possible to reliably escape by the cutout 14 of the heel counter 10.

Further, the length L ₁ in the front-rear direction from the most protruding point 30a at the rear end of the upper 3 to the tip of the lower support portion 11 of the heel counter 10 is set to L ₁ > 0.17 × L, and the ribs the length of the lower support portion 11 is configured to load center line G of the C _a passes through the lower support portion 11.

In this case, when the wearer P has landed from the sole heel rear end of the shoe 1, when trying to deform the bottom of the upper 3 with the deformation of the sole 2, the upper due to the load acting on the calcaneus C _A 3 can be effectively regulated by the lower support portion 11.

Further, the length L _u in the front-rear direction from the most protruding point 30a at the rear end of the upper 3 to the tip of the upper support portion 12 of the heel counter 10 is set to L _u > 0.17 × L. length of the upper support portion 12 is set so as load center line G of the C _a passes through the upper support portion 12.

In this case, when the deformation of the upper lower due to the load acting on the load center line G of the calcaneus C _A attempts to propagate to the upper top, deformation of the upper top can be effectively restricted by the upper support portion 12 as becomes, thereby, the calcaneus C _a top hold of the foot by the upper support portion 12 at the time of exercise when particular landing can be further improved.

Further, since the point 12e at the rear end of the upper edge 12a of the upper support portion 12 is disposed above the upper lower end (0.7 × H), the upper support portion 12 of the heel counter 10 is disposed. There can cover the top of the calcaneus C _a of the wearer's foot, it is possible to improve the hold of the calcaneus C _a by the upper support portion 12, the point 12a is disposed below the Shaft 31 of the shoe 1 Therefore, it is possible to prevent the upper support portion 12 of the heel counter 10 from inhibiting the flexibility of the mouth 31 of the shoe 1.

The position of the point 12e at the rear end of the upper support portion upper edge 12a of the heel counter 10 is set to a height of approximately (0.7 × H) from the upper lower end, and the most protruding point at the rear end of the upper 3 the position of 30a when set to the height position of the upper bottom (0.4 × H) is the vertical direction approximate center height position is calcaneus C _a of the notch 14 of the bottom portion 14a of the heel counter 10 Therefore, the upper and lower support portions 11 and 12 can be arranged substantially evenly above and below the notch 14.
<Second embodiment>

Although the example in which 12 is provided symmetrically on the shoe 1 is shown, the application of the present invention is not limited to this.

The length in the front-rear direction from the rear end of the shoe support of the upper support portion 12 may be varied between the inner side and the outer side of the shoe. FIG. 3 is a schematic plan view of the heel counter 10 according to the second embodiment of the present invention. In the second embodiment, the length L _u ′ on the outer side is longer than the length L _u on the inner side. In this case, it is possible to effectively prevent the legs from being thrown off at the time of landing. On the contrary, when the length in the front-rear direction on the inner shell side is increased, it is possible to effectively prevent the rotation of the foot when landing. In this way, it is possible to provide a shoe that matches the competition item or individual differences among shoe wearers.
<Third embodiment>
FIG. 4 shows a heel counter according to a third embodiment of the present invention. In the third embodiment, the upper support portion 12 is extended to the instep side of the upper of the shoe, and an eyelet hole 35 for inserting a shoelace is provided at the tip thereof.

In this case, by tightening the laces, it can be brought into close contact with the upper support portion 12 to the calcaneus C _A top, thereby, the calcaneus C _A top hold of the foot during exercise when particular landing As a result, it is possible to more reliably regulate the lateral movement of the heel of the foot that occurs at the time of landing.
<Fourth embodiment>
