Description

The present invention relates to a sensor device that can be attached to footwear, footwear, and a footwear set.

Conventionally, footwear such as shoes is known in which a small sensor device with a built-in sensor and communication device is housed in a recess in the sole. The sensor device can calculate various parameters related to exercise (e.g., calories burned, running distance, etc.) based on data measured by the sensor, and transmit the data measured by the sensor and the calculated parameters to a portable device such as a smartphone of the user. The user can then use the various parameters related to exercise to help manage their own health, etc. (see, for example, Patent Document 1).

This section describes an embodiment of the present invention.

First Embodiment
A first embodiment of the present invention will be described. In this embodiment, a shoe 1 will be described as an example of footwear, but other footwear such as sandals may be used. Also, the shoe 1 will be described as a right-foot shoe as an example, but it may be a left-foot shoe. Also, the present invention may be applied to both right-foot and left-foot shoes.

Figure 1 is a left side view of a shoe 1 according to this embodiment. The shoe 1 has a sole 10 and a sensor device 2 that can be attached to and detached from the midfoot when the sole 10 is divided into three parts in the front-rear direction: a forefoot part, a midfoot part, and a heel part.

The sole 10 has a midsole 11 and an outer sole 12. Depending on the manufacturing method of the shoe 1, the two may be an integrated part in which there is no distinction between them. An inner sole 13 may also be provided as appropriate. The sole 10 has a fitting recess 14 on the upper surface side of the midsole 11 that can accommodate the sensor device 2.

FIG. 2 is a diagram showing an example of the configuration of the sole 10 and the sensor device 2, and is a plan view of the shoe 1 as viewed from directly above (top view).
The accommodating recess 14 has a fitting shape that corresponds to the external shape of the sensor device 2 in a housed state in the midfoot portion of the midsole 11 when viewed from above. The midsole 11 is made of, for example, EVA resin (ethylene-vinyl acetate copolymer resin). Since EVA resin is highly flexible, the accommodating recess 14 can be fixed in a manner that closely fits and encases the sensor device 2 when the sensor device 2 is worn. The detailed shape of the accommodating recess 14 will be described later.

Next, the sensor device 2 will be described.
The sensor device 2 has a contour shape that is asymmetrical about an axis of symmetry A when housed in the housing recess 14 of the sole 10. The left and right of "asymmetrical" referred to here refer to the left and right when the sensor device 2 is housed in the housing recess 14. In this embodiment, since the shoe 1 is illustrated as being for a right foot, the axis of symmetry A faces the front-to-rear direction of the shoe 1, with the left corresponding to the inner side of the shoe and the right corresponding to the outer side of the shoe.

Figure 3 is a perspective view of the sensor device 2, Figure 4 is a front view of the sensor device 2, Figure 5 is a rear view of the sensor device 2, Figure 6 is a plan view of the sensor device 2, Figure 7 is a bottom view of the sensor device 2, Figure 8 is a left side view of the sensor device 2, and Figure 9 is a right side view of the sensor device 2.

The sensor device 2 has a main body 21 that stores a battery and electronic components, a lid 22 that is removable from the main body 21, and a fastener 23 for fastening the lid 22 to the main body 21. The battery is, for example, a button battery classified as a coin type. The electronic components include an electronic circuit board equipped with various electronic elements, and the electronic circuit board is equipped with a three-axis acceleration sensor, a microprocessor, an IC memory, a small wireless communication device, etc. Of course, other electronic components and circuit parts can be equipped. The three-axis acceleration sensor measures acceleration in each of the three orthogonal axes of X, Y, and Z. The measured values are stored in the IC memory as they are, or converted into parameter values representing the movement of the shoe 1 or parameter values related to the amount of exercise of the user of the shoe 1 by a predetermined arithmetic process by the microprocessor. The measured values and parameter values are then transmitted to an external device (for example, a smartphone owned by the user, a wearable computer with a communication function such as a smart watch or smart glasses, etc.) connected to the communication-connected device through the small wireless communication device by communication control of the microprocessor.

The sensor device 2 has a first surface 20 that is attached to the sole 10 of the shoe 1, and a second surface 30 that faces the first surface 20. The first surface 20 and the second surface 30 are generally parallel to each other.

The first surface 20 includes a first side end 41, a second side end 42, a third side end 43, and a fourth side end 44, with the first side end 41 facing the third side end 43 and the second side end 42 facing the fourth side end 44.

A first chamfered portion 24 is formed on a part of the first side end portion 41 and a part of the fourth side end portion 44. Furthermore, the first chamfered portion 24 includes a first inclined surface 24a and a second inclined surface 24b. The first inclined surface 24a and the second inclined surface 24b are inclined toward the same inclination direction (e.g., the first end portion 51) at different inclination angles. In this embodiment, the inclination angle of the first inclined surface 24a is gentler than the inclination angle of the second inclined surface 24b. The first chamfered portion 24 is formed only on the first surface 20 and does not extend to the second surface 30.

A second chamfered portion 25 is formed on a part of the first side end portion 41 and a part of the second side end portion 42. Furthermore, the second chamfered portion 25 includes a third inclined surface 25a and a fourth inclined surface 25b. The third inclined surface 25a and the fourth inclined surface 25b are inclined toward the same inclination direction (e.g., the second end portion 52) at different inclination angles. In this embodiment, the inclination angle of the third inclined surface 25a is gentler than the inclination angle of the fourth inclined surface 25b. The second chamfered portion 25 is formed only on the first surface 20 and does not extend to the second surface 30.

The first chamfered portion 24 (first inclined surface 24a and second inclined surface 24b) and the second chamfered portion 25 (third inclined surface 25a and fourth inclined surface 25b) are formed to be linearly symmetrical with respect to the midline B of the first side end portion 41 as the axis of symmetry, and are partially in contact with each other (in this embodiment, the first inclined surface 24a and the third inclined surface 25a are in contact with each other).

The area of the first inclined surface 24a and the area of the third inclined surface 25a are approximately the same. The area of the second inclined surface 24b and the area of the fourth inclined surface 25b are approximately the same. The area of the first inclined surface 24a is larger than the area of the second inclined surface 24b. The area of the third inclined surface 25a is larger than the area of the fourth inclined surface 25b. The angle between the inclination direction of the first chamfered portion 24 (the first inclined surface 24a and the second inclined surface 24b) and the inclination direction of the second chamfered portion 25 (the third inclined surface 25a and the fourth inclined surface 25b) is an angle of 60 degrees or more and 120 degrees or less, and in this embodiment, it is about 90 degrees.

In this way, the first chamfered portion 24 (first inclined surface 24a and second inclined surface 24b) and the second chamfered portion 25 (third inclined surface 25a and fourth inclined surface 25b) are formed on the first side end portion 41, the second side end portion 42, and the fourth side end portion 44, and are not formed on the third side end portion 43 side. Note that the first chamfered portion 24 (first inclined surface 24a and second inclined surface 24b) and the second chamfered portion 25 (third inclined surface 25a and fourth inclined surface 25b) can be formed by C-face machining, etc.

The second surface 30 of the main body 21 is provided with a pressing portion 31 for pressing the sensor device 2 when mounting the sensor device 2 in the storage recess 14 or removing the sensor device 2 from the storage recess 14.

Next, we will explain the relationship between the sensor device 2 and the storage recess 14 of the shoe 1. Figure 10 is a diagram showing the relationship between the storage recess 14 of the shoe 1 and the sensor device 2.

The storage recess 14 is shaped to fit the sensor device 2 into the sole 11. However, the bottom surface of the storage recess 14 is not flush, and a portion of the bottom surface of the storage recess 14 toward the heel of the shoe 1 is recessed. The depth of this recess (recess) 141 (blackened portion in FIG. 10) is such that the protruding fastener 23 of the sensor device 1 fits into the recess at the position corresponding to the fastener 23 of the sensor device 1, and the depth increases from that portion, sloping to the end of the storage recess 14 toward the heel.

The sensor device 2 is accommodated in the accommodation recess 14 so that its fastening portion 23 fits into the semicircular recess 142 of the accommodation recess 14. The semicircular recess 142 of the accommodation recess 14 can be used as a guide when attaching the sensor device 2 in the correct position. For example, if an attempt is made to fit the sensor device 2 into the accommodation recess 14 without taking the correct accommodation posture, the convex shape of the fastening portion 23 will not fit into the position of the recess 142, and the sensor device 2 will not fit properly into the accommodation recess 14, and the user will be able to immediately notice that the orientation of the sensor device 2 is incorrect.

In addition, when the sensor device 2 is attached to the storage recess 14, the bottom surface of the storage recess 14 does not contact the first chamfered portion 24 (first inclined surface 24a and second inclined surface 24b) and the second chamfered portion 25 (third inclined surface 25a and fourth inclined surface 25b) of the sensor device 2. Furthermore, the side wall of the storage recess 14 does not contact the first chamfered portion 24 (first inclined surface 24a and second inclined surface 24b) and the second chamfered portion 25 (third inclined surface 25a and fourth inclined surface 25b) of the sensor device 2.

The sole 11 is made of a material such as EVA resin (ethylene-vinyl acetate copolymer resin), and since EVA resin is highly flexible, the storage recess 14 formed in the sole 11 can press the attached sensor device 2 from the side wall of the storage recess 14, fixing the sensor device 2 in a tight contact state.

Next, a case where the sensor device 2 is removed from the accommodation recess 14 will be described.
FIG. 11 is a schematic diagram showing a case where the sensor device 2 is removed from the accommodation recess 14. As shown in FIG.

When removing the sensor device 2 from the storage recess 14, the pressing portion 31 of the sensor device 2 is pressed with a finger or the like. Then, the body 21 side of the sensor device 2 tilts toward the recess 141 of the storage recess 14, a part of the surface 20 on the body 21 side comes into contact with the bottom surface of the recess 141, and the lid 22 side of the sensor device 2 floats up from the storage recess 14.

What is important here is that the first chamfered portion 24 (first inclined surface 24a and second inclined surface 24b) and the second chamfered portion 25 (third inclined surface 25a and fourth inclined surface 25b) of the sensor device 2 are not in contact with the side wall of the storage recess 14. As a result, the area where the side surface of the sensor device 2 on the lid portion 22 side comes into contact with the side wall of the storage recess 14 is reduced.

As a result, when the lid portion 22 side of the sensor device 2 is lifted up, friction between the side surface of the body 21 of the sensor device 2 and the side wall of the storage recess 14 is reduced, so that the lid portion 22 side of the sensor device 2 can be lifted up easily, and the sensor device 2 can be removed. This configuration is particularly suitable for footwear worn by users with weak strength, such as children's shoes.

In addition, when the user performs an exercise such as twisting the ankle, a torque acts on the sensor device 2 housed in the sole 10 of the shoe 1 around the vertical axis relative to the sole 10. This torque generates a twist between the outer periphery of the sensor device 2 and the side wall of the storage recess 14. However, according to this embodiment, by configuring the first chamfered portion 24 and the second chamfered portion 25 as two slopes with different inclinations, it is possible to reduce the contact area between the sensor device 2 and the side wall of the storage recess 14, and also to reduce the gap between the first chamfered portion 24 and the second chamfered portion 25 and the bottom surface and side wall of the storage recess 14, thereby minimizing the misalignment of the sensor device 2 caused by the twist. As a result, the storage state of the sensor device 2 can be stably maintained.

<First Modification of the First Embodiment>
A first modification of this embodiment will be described.
FIG. 12 is a diagram showing the relationship between the storage recess 14 of the shoe 1 and the sensor device 2 in the first modification of the embodiment.

In the first modified example of this embodiment, a second recess (recess) 143 (blackened portion in FIG. 11) is formed on the bottom surface of the accommodation recess 14 corresponding to the positions of the first chamfered portion 24 and the second chamfered portion 25. The second recess 143 slopes from the position corresponding to the chamfering start position of the first chamfered portion 24 and the second chamfered portion 25 to the end of the accommodation recess 14 in the forefoot direction while increasing in depth.

By providing the second recess 143, the gap between the first chamfered portion 24 and the second chamfered portion 25 and the bottom surface and side wall of the storage recess 14 is increased, making it easier to remove the sensor device 2 from the storage recess 14.

<Modification 2 of the First Embodiment>
In the present embodiment, an example has been described in which the accommodating recess 14 is directly formed in the sole 11. However, a recess-forming part having a shape similar to that of the accommodating recess 14 may be embedded in the sole 11. The recess-forming part is made of, for example, TPU resin (thermoplastic polyurethane resin).

Second Embodiment
A second embodiment of the present invention will be described. The second embodiment differs from the first embodiment in the shape of the storage recess 14 of the shoe 1. Fig. 13 is a diagram showing the relationship between the storage recess 14 of the shoe 1 and the sensor device 2 in the second embodiment.

The storage recess 14 has a fitting recess shape that allows the sensor device 2 to fit into the sole 11, and is made up of a first recess 151 and a second recess 152 (the blackened portion in Figure 13).

The first recess 151 is located at a position corresponding to the lid portion 22 side of the sensor device 2, and has a generally trapezoidal shape that narrows toward the toe. The depth of the first recess 151 is deeper than the height of the side surface of the sensor device 2, and is formed so that the side wall of the first recess 151 and the side surface of the lid portion 22 side of the sensor device 2 are in contact with each other. When the sensor device 2 is accommodated in the accommodation recess 14, the bottom surface of the first recess 151 and the surface 20 of the lid portion 22 side of the sensor device 2 are in a positional relationship facing each other, and are in contact with each other in part. However, the bottom surface of the first recess 151 does not contact the first chamfered portion 24 (first inclined surface 24a and second inclined surface 24b) and the second chamfered portion 25 (third inclined surface 25a and fourth inclined surface 25b) of the sensor device 2. In addition, the side wall of the storage recess 14 does not contact the first chamfered portion 24 (first inclined surface 24a and second inclined surface 24b) and the second chamfered portion 25 (third inclined surface 25a and fourth inclined surface 25b) of the sensor device 2.

The second recess 152 is located at a position corresponding to the main body 21 side of the sensor device 2, and its depth is deeper than the depth of the first recess 151, and is deep enough that when the sensor device 2 is properly accommodated in the accommodation recess 14, the bottom surface of the second recess 152 does not come into contact with the surface 20 on the main body 21 side of the sensor device 2 (the side facing the first chamfered portion 24 and the second chamfered portion 25). The depth of the second recess 152 is, for example, about half the height of the side of the sensor device 2, and deeper than the first recess 151. Due to this shape, when the sensor device 2 is properly accommodated in the accommodation recess 14, the surface 20 on the main body 21 side of the sensor device 2 is located above the bottom surface of the second recess 152. In addition, a protruding column portion 153 is formed on both walls of the second recess 152 near the boundary with the first recess 151. The protruding pillars 153 support (clamp) the sides of the sensor device 2 when the sensor device 2 is attached and when the sensor device 2 can be removed from the storage recess 14. The sensor device 2 is clamped by the protruding pillars 153, allowing the sensor device 2 to be fixed to the storage recess 14.

Next, a case where the sensor device 2 is removed from the accommodation recess 14 will be described.
FIG. 14 is a schematic diagram showing a case where the sensor device 2 is removed from the accommodation recess 14 in the second embodiment.

When removing the sensor device 2 from the storage recess 14, the pressing portion 31 of the sensor device 2 is pressed with a finger or the like. Then, the body 21 side of the sensor device 2 tilts toward the second recess 152 of the storage recess 14, a part of the surface 20 on the body 21 side comes into contact with the bottom surface of the second recess 152, and the lid 22 side of the sensor device 2 rises up from the storage recess 14. In other words, a part of the first chamfered portion 24 and the second chamfered portion 25 of the sensor device 2 are exposed.

What is important here is that the first chamfered portion 24 (the first inclined surface 24a and the second inclined surface 24b) and the second chamfered portion 25 (the third inclined surface 25a and the fourth inclined surface 25b) of the sensor device 2 are not in contact with the side wall and the bottom surface of the storage recess 14. As a result, the area where the side surface of the lid portion 22 side of the sensor device 2 contacts the side wall of the storage recess 14 is reduced. This reduces friction between the side surface of the body 21 of the sensor device 2 and the side wall of the storage recess 14 when the lid portion 22 side of the sensor device 2 is lifted up, so that the lid portion 22 side of the sensor device 2 can be easily lifted up, and the sensor device 2 can be easily removed. This configuration is particularly suitable for footwear for users with weak strength, such as children's shoes.
Furthermore, even if the main body 21 side of the sensor device 2 is tilted toward the second recess 152, the sensor device 2 is clamped by the protruding pillar portion 153, so that the sensor device 2 will not suddenly come off and it is possible to prevent the sensor device 2 from falling when being removed.
