DESCRIPTION OF EMBODIMENTS

First Exemplary Embodiment

First, explanation follows regarding a first exemplary embodiment of technology disclosed herein.

An electronic device 10 according to the first exemplary embodiment illustrated in FIG. 1 is a wearable electronic device, and includes a wearing band 20 and an electronic device body 11.

The wearing band 20 is, for example, a band that is worn on a predetermined location of the body of a person, such as the arm, the waist, or the head. The wearing band 20 is formed in a belt shape with its length direction in an L direction and its width direction in a W direction. The wearing band 20 includes plural first zigzag springs 21, plural second zigzag springs 22, a connection section 23, a connected section 24, and a mounting section 25.

The plural first zigzag springs 21, the plural second zigzag springs 22, the connection section 23, the connected section 24, and the mounting section 25 form a band body 26 of the wearing band 20. The plural first zigzag springs 21, the plural second zigzag springs 22, the connection section 23, the connected section 24, and the mounting section 25 form the wearing band 20 of the first exemplary embodiment. Thus, in the first exemplary embodiment, the wearing band 20 is synonymous with the band body 26.

The plural first zigzag springs 21 and the plural second zigzag springs 22 are arrayed in the L direction and the W direction. The W direction intersects (for example, is orthogonal to) the L direction.

As illustrated in FIG. 2, each of the plural first zigzag springs 21 is formed having its axial direction in the L direction. Each of the plural first zigzag springs 21 includes plural S-shaped portions arranged along the L direction. The plural first zigzag springs 21 form a section stretching and contracting in the length direction of the wearing band 20 (the band body 26).

On the other hand, each of the plural second zigzag springs 22 is formed having its axial direction in the W direction. Each of the plural second zigzag springs 22 includes plural S-shaped portions arranged along the W direction. The plural second zigzag springs 22 form a section stretching and contracting in the width direction of the wearing band 20 (the band body 26).

Note that in the first zigzag springs 21, the plural S-shaped portions arranged along the L direction may also be understood to be plural crank-shaped portions arranged along the L direction. Similarly, in the second zigzag springs 22, the plural S-shaped portions arranged along the W direction may also be understood to be plural crank-shaped portions arranged along the W direction.

As illustrated in FIG. 3, each of the first zigzag springs 21 has a substantially regular octagonal shaped outline profile in plan view. Namely, each first zigzag spring 21 has plural line elements 31 extending in the W direction and arranged alongside each other in the L direction. Length direction end portions of the plural line elements 31 are linked together to form each first zigzag spring 21 in a substantially regular octagonal shape. Each line element 31 is formed in a plate shape with its plate thickness direction in the L direction.

Similarly, as illustrated in FIG. 4, each of the second zigzag springs 22 has a substantially regular octagonal shaped outline profile in plan view. Namely, each second zigzag spring 22 has plural line elements 32 extending in the L direction and arranged alongside each other in the W direction. Length direction end portions of the plural line elements 32 are linked together to form each second zigzag spring 22 in a substantially regular octagonal shape. Each line element 32 is formed in a plate shape with its plate thickness direction in the W direction. The line elements 31 of the first zigzag springs 21 and the line elements 32 of the second zigzag springs 22 are formed having the same plate thickness as each other.

Moreover, as illustrated in FIG. 2, the size (the lateral width and the length) of the first zigzag springs 21 is larger than that of the second zigzag springs 22. Further, due to the first zigzag springs 21 having a larger size than the second zigzag springs 22, the first zigzag springs 21 have a smaller spring constant (deform more readily) than the second zigzag springs 22. Due to the first zigzag springs 21 having a larger size (smaller spring constant) than the second zigzag springs 22, the wearing band 20 illustrated in FIG. 1 is thus anisotropic in that the wearing band 20 stretches more readily in the L direction than in the W direction.

Further, as illustrated in FIG. 5, the line elements 31 of the first zigzag spring 21 extend in the W direction and are arranged alongside each other in the L direction, such that tensile and bending load F causes the first zigzag spring 21 to stretch readily in the L direction and to bend readily about an axis parallel to the W direction. On the other hand, as illustrated in FIG. 6, the line elements 32 of the second zigzag spring 22 extend in the L direction and are arranged alongside each other in the W direction, such that even when applied with tensile and bending load F, the second zigzag spring 22 does not readily stretch in the L direction and does not readily bend about an axis parallel to the W direction. In the wearing band 20 illustrated in FIG. 1, the size of each first zigzag spring 21 is larger than that of each second zigzag spring 22, and so the wearing band 20 has the property of readily bending about an axis parallel to the W direction.

The plural first zigzag springs 21 and the plural second zigzag springs 22 used to achieve such a property are more specifically arrayed as follows. Namely, as illustrated in FIG. 7, the plural first zigzag springs 21 form plural first spring rows 41 that each include plural of the first zigzag springs 21 arranged along the L direction. The plural first spring rows 41 are arranged alongside each other in the W direction. Coupling portions 43 are formed between adjacent first zigzag springs 21 in each first spring row 41.

On the other hand, as illustrated in FIG. 8, the plural second zigzag springs 22 form plural second spring rows 42 that each include plural second zigzag springs 22 arranged along the W direction. The plural second spring rows 42 are arranged alongside each other in the L direction. Coupling portions 44 are formed between adjacent second zigzag springs 22 in each second spring row 42.

Further, as illustrated in FIG. 7, each the plural second zigzag springs 22 couples a coupling portion 43 of one first spring row 41 out of the plural first spring rows 41 to a coupling portion 43 of another first spring row 41 that is adjacent to the one first spring row 41. As illustrated in FIG. 2, the coupling portions 43 and the coupling portions 44 are connected to each other in cross shapes.

By being arrayed as described above, the plural first zigzag springs 21 and the plural second zigzag springs 22 are formed in the same single plane extending in the L direction and the W direction. Further, by forming the plural first zigzag springs 21 and the plural second zigzag springs 22 in the same single plane extending in the L direction and the W direction, the wearing band 20 is formed in a plate shape.

As illustrated in FIG. 1, the connection section 23 is formed at one length direction end of the wearing band 20, and includes plural protrusions 53 arranged alongside each other in the W direction. On the other hand, the connected section 24 is formed at the other length direction end of the wearing band 20, and includes plural recesses 54 arranged alongside each other in the W direction. The connection section 23 is connected to the connected section 24 by fitting the plural protrusions 53 into the respective plural recesses 54. Further, the wearing band 20 is formed into a ring shape (tube shape) with its peripheral direction in the L direction by connecting the connection section 23 to the connected section 24. The wearing band 20 is able to return to a belt shape by releasing the connection between the connection section 23 and the connected section 24.

The mounting section 25, for example, is formed at a length direction central section of the wearing band 20. The mounting section 25 is formed in an elongated shape with its short direction in the L direction and its length direction in the W direction. The mounting section 25 is formed in a plate shape and is formed from a hard material. The plural first zigzag springs 21 and the plural second zigzag springs 22 are arrayed at both L direction sides of the mounting section 25.

The plural first zigzag springs 21, the plural second zigzag springs 22, the connection section 23, the connected section 24, and the mounting section 25 described above are integrally formed to the wearing band 20. The wearing band 20 is formed of a resin, for example. In cases in which the wearing band 20 is formed of a resin, the wearing band 20 may be manufactured using, for example, a three-dimensional printer, resin molding, or a processing method such as punching.

The electronic device body 11 is mounted to the mounting section 25. The electronic device body 11 is, for example, configured by an electronic unit including a sensor, a computation element, a storage element, a battery, a display device, an operation switch, a casing, and the like. Note that a semiconductor chip may be employed as the electronic device body 11.

The electronic device 10 configured as described above is, for example, used as follows. Namely, in FIG. 9, the electronic device 10 is a wristband type wearable device, and the wearing band 20 is worn on the wrist of a user. Further, in FIG. 10, the electronic device 10 is a waist-belt type wearable device, and the wearing band 20 is worn on the waist of a user. Moreover, in FIG. 11, the electronic device 10 is a headband type wearable device, and the wearing band 20 is worn on the head of a user.

The electronic device 10 is not limited to the examples of usage illustrated in FIG. 9 to FIG. 11, and the electronic device 10 may be of a type worn on a location of the body other than those described above, such as a ring type or a bracelet type. The length and width of the wearable band 20 are set appropriately in accordance with its location on the body, this being where the wearing band 20 is to be worn.

Explanation follows regarding operation and advantageous effects of the first exemplary embodiment.

According to the first exemplary embodiment as described above, the wearing band 20 includes the plural first zigzag springs 21 and the plural second zigzag springs 22 as illustrated in FIG. 1, and is thus made lightweight. Moreover, the first zigzag springs 21 having axial directions in the length direction of the wearing band 20 have a larger size (smaller spring constant) than the second zigzag springs 22 having axial directions in the width direction of the wearing band 20.

Thus, when the wearing band 20 is worn on the body, the wearing band 20 stretches readily in the length direction (peripheral direction) and the wearing band 20 bends readily about an axis parallel to the width direction. Further, the wearing band 20 also stretches in the width direction because of the second zigzag springs 22, such that even complicated undulations in the body can be accommodated. Thus, the wearing band 20 is not uncomfortable when worn on the body, since the wearing band 20 is flexible and conforms well to the complicated shape of the body. This enables the comfort of the wearing band 20 when worn on the body to be improved.

The wearing band 20 is formed in a belt shape, the connection section 23 is formed at one length direction end of the wearing band 20, and the connected section 24 connected to the connection section 23 is formed at the other length direction end of the wearing band 20. The wearing band 20 can thereby be formed into a ring shape (tube shape) by connecting the connection section 23 to the connected section 24.

Moreover, since the wearing band 20 readily stretches in the length direction (peripheral direction), the wearing band 20 can be put on the body (for example, on the wrist) in the ring shape as-is. This enables the convenience of the wearing band 20 to be improved, since there is no need to fasten and unfasten a belt, such as with the band of a wristwatch.

Further, in a state in which the connection section 23 and the connected section 24 are not connected to each other, the wearing band 20 has a belt shape (flat face shape). Thus, the wearing band 20 can be manufactured in a belt shaped state such that the wearing band 20 is easy to manufacture, and moreover, as long as the wearing band 20 is placed in the belt shape when not in use, the wearing band 20 has the advantage of being easy to store.

Further, the plural first zigzag springs 21 and the plural second zigzag springs 22 are formed in the same single plane extending in the length direction and the width direction of the wearing band 20. The wearing band 20 is thus configured in a plate shape. Accordingly, bulkiness of the wearing band 20 can be suppressed by making the wearing band 20 thin, enabling the comfort of the wearing band 20 when worn on the body to be further improved.

Further, as illustrated in FIG. 7, the plural first zigzag springs 21 form the plural first spring rows 41 including plural of the first zigzag springs 21 arranged along the length direction of the wearing band 20. On the other hand, as illustrated in FIG. 8, the plural second zigzag springs 22 form the plural second spring rows 42 including plural of the second zigzag springs 22 arranged along the width direction of the wearing band 20. Further, as illustrated in FIG. 7, each of the plural second zigzag springs 22 couples a coupling portion 43 of one first spring row 41 out of the plural first spring rows 41 to a coupling portion 43 of another first spring row 41 that is adjacent to the one first spring row 41.

The plural first zigzag springs 21 and the plural second zigzag springs 22 can thereby be disposed in a dense arrangement by arraying the plural first zigzag springs 21 and the plural second zigzag springs 22 as described above. This enables the space efficiency of the wearing band 20 to be improved.

Further, as illustrated in FIG. 1, the hard mounting section 25 is provided to the wearing band 20 separately from the plural first zigzag springs 21 and the plural second zigzag springs 22. Thus, the electronic device body 11 that is weak with respect to bending can be mounted to the mounting section 25, enabling failure of or damage to the electronic device body 11 to be suppressed.

Explanation follows regarding a modified example of the first exemplary embodiment.

Although the wearing band 20 is formed in a belt shape (see FIG. 1) in the first exemplary embodiment described above, the wearing band 20 may be formed in a ring shape (see FIG. 9 to FIG. 11). As a method for forming the wearing band 20 into a ring shape, for example, the wearing band 20 is manufactured in a belt shape and then the two length direction ends of the wearing band 20 are joined together by welding, adhesion, or the like as a method to configure the wearing band 20 into a ring shape.

Further, each of the first zigzag springs 21 has a substantially regular octagon shaped outline profile in plan view (see FIG. 3). However, as illustrated in FIG. 12, the outline profiles of the first zigzag springs 21 may be configured by substantially circular shapes in plan view. Similarly, each of the second zigzag springs 22 has a substantially regular octagon shaped outline profile in plan view (see FIG. 4). However, as illustrated in FIG. 13, the outline profiles of the second zigzag springs 22 may be configured by substantially circular shapes in plan view.

Further, the line elements 31 forming the first zigzag springs 21 are flat plate shaped (see FIG. 3). However, as illustrated in FIG. 14, the line elements 31 forming the first zigzag springs 21 may be rounded rod shaped. Similarly, the line elements 32 forming the second zigzag spring 22 are flat plate shaped (see FIG. 4). However, as illustrated in FIG. 15, the line elements 32 forming the second zigzag spring 22 may be rounded rod shaped.

The size of the first zigzag springs 21 is larger than that of the second zigzag springs 22, and so the spring constant of the first zigzag springs 21 is smaller than that of the second zigzag springs 22. However, the size of the first zigzag springs 21 may be configured to be smaller than or the same as the size of the second zigzag springs 22 so long as the spring constant of the first zigzag springs 21 is smaller than the spring constant of the second zigzag springs 22.

Second Exemplary Embodiment

Explanation follows regarding a second exemplary embodiment of technology disclosed herein.

An electronic device 70 according to the second exemplary embodiment illustrated in FIG. 16 and FIG. 17 has a structure modified from that of the electronic device 10 (see FIG. 1) according to the first exemplary embodiment described above as follows.

Namely, a wearing band 20 of the electronic device 70 according to the second exemplary embodiment includes a detachment section 71 in addition to the band body 26. The detachment section 71 includes a mounting section 25, and an electronic device body 81 is attached to and detached from the detachment section 71. The detachment section 71 includes, as an example, a pair of arm portions 72. The pair of arm portions 72 project out in a direction normal to the front surface of the mounting section 25. Hook portions 73 projecting out toward the inside of the pair of arm portions 72 are formed at leading end portions of the pair of arm portions 72.

Further, the electronic device 70 includes the electronic device body 81 configured as a separate body from the mounting section 25. The electronic device body 81 is, for example, configured by an electronic unit including a sensor, a computation element, a storage element, a battery, a display device, an operation switch, a casing, and the like. When the electronic device body 81 is mounted to a predetermined location on the mounting section 25, the pair of arm portions 72 engage with groove portions 83 formed in side faces of the electronic device body 81 and the pair of hook portions 73 latch onto an upper face of the electronic device body 81, thereby fixing the electronic device body 81 to the mounting section 25.

On the other hand, when the electronic device body 81 is removed from the mounting section 25, for example, the pair of arm portions 72 elastically deform in a mutually separating direction, such that the electronic device body 81 is removed from between the pair of arm portions 72.

According to the second exemplary embodiment, the detachment section 71 which the electronic device body 81 is attached to and detached from is provided to the mounting section 25 of the wearing band 20 in this manner, enabling the convenience of the electronic device 70 to be improved.

Note that in the second exemplary embodiment, the pair of arm portions 72 may be tilted in the mutually separating direction by a release mechanism or the like to remove the electronic device body 81 from between the pair of arm portions 72.

Further, the detachment section 71 may have any structure, so long as attachment and detachment of the electronic device body 81 is enabled.

Third Exemplary Embodiment

Explanation follows regarding a third exemplary embodiment of technology disclosed herein.

An electronic device 90 according to the third exemplary embodiment illustrated in FIG. 18 has a structure modified from that of the electronic device 10 (see FIG. 1) according to the first exemplary embodiment described above as follows.

Namely, in the electronic device 90 according to the third exemplary embodiment, a semiconductor chip 91 is mounted to the mounting section 25. The semiconductor chip 91 is an example of an electronic device body. The semiconductor chip 91 may be packaged on the front surface of the mounting section 25, or may, for example, be embedded in the mounting section 25 using insert molding or the like.

Further, the wearing band 20 includes a pair of conductive patterns 92 in addition to the band body 26. Each conductive pattern 92 is formed on the band body 26 to the mounting section 25 and to several first zigzag springs 21 adjacent to the mounting section 25.

Each conductive pattern 92 is formed, for example, by a thin film or the like. Each conductive pattern 92 is configured by, for example, a circuit wire, an antenna, or the like, and is electrically connected to the semiconductor chip 91.

The portion of each conductive pattern 92 formed on the first zigzag springs 21 is formed in a zigzag shape running along the first zigzag springs 21. Note that the conductive patterns 92 may be formed on the front surface or the back surface of the mounting section 25 and the first zigzag springs 21, or may, for example, be embedded in the mounting section 25 and the first zigzag spring 21 by insert molding or the like.

According to the third exemplary embodiment, the conductive patterns 92 are thus integrally formed to the wearing band 20, enabling the structure of the wearing band 20 to be simplified in comparison to a case in which, for example, a conductive member separate to the wearing band 20 is employed. This enables the ease of use of the electronic device 90 to be improved.

Note that as illustrated in FIG. 19, in the third exemplary embodiment, an electronic device body 101 including a display device 102 may be mounted to the mounting section 25.

Further, the conductive pattern 92 may be formed spanning the mounting section 25, the first zigzag springs 21, the connection section 23, and the connected section 24 of the band body 26. Moreover, the conductive pattern 92 may be formed to the second zigzag springs 22. The conductive pattern 92 is capable of being formed on any out of at least the mounting section 25, the first zigzag springs 21, the second zigzag springs 22, the connection section 23, and the connected section 24.

Further, the conductive pattern 92 may be applied to the wearing band 20 of the second exemplary embodiment (see FIG. 16 and FIG. 17) including the detachment section 71 described above.

Fourth Exemplary Embodiment

Explanation follows regarding a fourth exemplary embodiment of technology disclosed herein.

A wearing band 120 according to the fourth exemplary embodiment illustrated in FIG. 20 and FIG. 21 has a structure modified from that of the wearing band 20 (see FIG. 1) according to the first exemplary embodiment described above as follows.

Namely, in the wearing band 120 according to the fourth exemplary embodiment, the size of the second zigzag springs 22 is larger than that of the first zigzag springs 21. Further, the second zigzag springs 22 have a smaller spring constant than that of the first zigzag springs 21 due to the size of the second zigzag springs 22 being larger than that of the first zigzag springs 21.

Due to the second zigzag springs 22 having a larger size (smaller spring constant) than the first zigzag springs 21, the wearing band 120 according to the fourth exemplary embodiment is anisotropic in that the wearing band 120 stretches more readily in its width direction than in its length direction. Further, in the wearing band 120, the size of the second zigzag springs 22 is larger than that of the first zigzag springs 21, and so the wearing band 120 also has the property of readily bending about an axis parallel to its length direction.

The wearing band 120 according to the fourth exemplary embodiment is applied to a location on the body where it is possible to exploit its property of being anisotropic, in that the wearing band 120 stretches more readily in its width direction than in its length direction, and its property of readily bending about an axis parallel to its length direction.

According to the fourth exemplary embodiment, the wearing band 120 is made lightweight by including the plural first zigzag springs 21 and the plural second zigzag springs 22. Moreover, the second zigzag springs 22 having axial directions in the width direction of the wearing band 120 are larger in size (have a smaller spring constant) than the first zigzag springs 21 having axial directions in the length direction of the wearing band 120.

Thus, when the wearing band 120 is worn on the body, the wearing band 120 stretches readily in its width direction and the wearing band 120 bends readily about an axis parallel to its length direction. Further, the wearing band 120 also stretches in its length direction because of the first zigzag springs 21, such that even complicated undulations in the body can be accommodated As explained above, the wearing band 120 is not uncomfortable when worn on the body, since the wearing band 120 is flexible and conforms well to the complicated shape of the body. This enables the comfort of the wearing band 120 when worn on the body to be improved.

Note that in the fourth exemplary embodiment, the size of the second zigzag springs 22 is larger than that of the first zigzag springs 21, and so the spring constant of the second zigzag springs 22 is smaller than that of the first zigzag springs 21. However, the size of the second zigzag springs 22 may be configured to be smaller than or the same as the size of the first zigzag springs 21 so long as the spring constant of the second zigzag springs 22 is smaller than the spring constant of the first zigzag springs 21.

Further, the modified example of the first exemplary embodiment, the detachment section 71 of the second exemplary embodiment (see FIG. 16 and FIG. 17), and the conductive pattern 92 of the third exemplary embodiment (see FIG. 18 and FIG. 19) described above may be applied to the wearing band 120 according to the fourth exemplary embodiment.
