[0009] [First embodiment] Hereinafter, a band 10 and a wearable device 1 (wearable device) according to a first embodiment of the present invention will be described with reference to Figs. 1 to 3. Fig. 1 is a perspective view showing the configuration of the band 10. Fig. 2 is an explanatory diagram of the band 10, where (a) shows a top view seen from the axial direction, and (b) and (c) show side views, respectively. Figs. 3(a) and (b) are explanatory diagrams showing a method of wearing the band. Note that in each diagram, the configuration is shown in outline by enlarging, reducing, or omitting as appropriate. In this embodiment, for example, the wearable device 1 will be described with the side facing the living body when worn as the back side, and the side facing outward when worn as the front side. For example, the wearable device 1 is worn in a position where the back side of the device terminal 20 faces the arm to which it is worn.

[0010] As shown in FIG. 1, the wearable device 1 includes a band 10 and a device terminal 20 attached to the band 10. In this embodiment, the wearable device 1 is attached to a part of a living body in which the size of the band 10 in one direction is different from the size of the band 10 in another direction that intersects or is perpendicular to the one direction. For example, the wearable device 1 is a wristwatch that has a watch function and is attached to the outer periphery of a human arm 101 or wrist 100. The wrist thickness T0 is smaller than the wrist width W0, and the band 10 is attached to the outer periphery of the wrist 100, which is the end of the arm 101 on the hand side, with the arm's longitudinal direction aligned with the axial direction. The wrist width W0 is the length of the wrist in the short direction on a plane parallel to the palm or the back of the hand. The wrist thickness T0 is the length of the wrist in the short direction perpendicular to the wrist width W0. The "wrist width seen from above" on which the wristwatch case rests is about 50 mm to 70 mm. The band 10 is configured in a spiral shape, and has an opening S through which the object to be worn passes between one end 12a and the other end 13a. The band 10 is configured to move in the direction of the spiral axis C1 while rotating around the spiral axis C1 on the outer periphery of the wrist 100. The band 10 is also formed in a belt shape curved in a spiral shape. For example, the band 10 is circular when viewed from one direction of the spiral axis C1, centered on the spiral axis C1, and extends in a direction inclined with respect to the direction along the spiral axis C1. For example, the curvature and inclination angle of each part of the band 10 may be constant, or may be configured differently depending on the part. Also, a part of the band 10 may not be spiral, and may be configured in an arc shape perpendicular to the spiral axis C1, for example.

[0011] The band 10 has a curved shape along a circle having a predetermined inner diameter Φ1 when viewed from the axial direction, and extends spirally in a direction inclined at a predetermined angle with respect to the spiral axis C1. That is, the band 10 extends in a direction inclined to the axial direction along a predetermined circumferential direction from the end 12a on one end side to the end 13a on the other end side.

[0012] The band 10 has shape retention. For example, the shape retention is such that, when worn and used without application of a predetermined external force, elastic deformation such as bending deformation does not occur, the curvature of the curved portion does not change, and the width of the opening S1 is maintained at a predetermined value or within a predetermined range. That is, the band 10 does not elastically deform and the width of the opening S does not change when worn or in the middle of being worn. For example, the band 10 is made of a hard material such as hard resin, metal, stone, wood, and ceramic. The surface of the band 10 may be covered with an elastically deformable material for the purpose of comfort and to prevent scratches.

[0013] The band 10 is configured by forming a belt-shaped member having a predetermined width w1 and thickness t1 in a spiral shape with a predetermined number of turns in two directions perpendicular to or intersecting the extension direction.

[0014] The band 10 includes an attachment portion 11 on which, for example, the device terminal 20 is disposed. In the following description, in the extension direction when the band 10 is worn, a portion provided on the wrist side is referred to as a first curved portion 12, and a portion on the elbow side is referred to as a second curved portion 13. For example, in this embodiment, one side of the attachment portion 11 on the band 10 to which the device terminal 20 is attached is referred to as the first curved portion 12, and the other side is referred to as the second curved portion 13.

[0015] That is, the band 10 is integrally provided with a first curved portion 12 that extends spirally to one side from the mounting portion 11 to which the device terminal 20 is attached, and a second curved portion 13 that extends spirally to the other side from the mounting portion 11.

[0016] The device terminal 20 is directly or indirectly attached to the attachment portion 11. For example, the attachment portion 11 has a flat joint portion 11a on the front side thereof, which is joined to the rear surface of the device terminal 20.

[0017] The first curved portion 12 extends to one end side of the attachment portion 21 and is curved with a predetermined radius of curvature. When the attachment portion 21 is placed on the back side of the wrist 100, the first curved portion 12 is formed to a length that passes through one side of the wrist 100 and the palm side of the wrist 100 to the other side.

[0018] The second curved portion 13 extends to the other end side of the attachment portion 21 and is curved with a predetermined radius of curvature. The second curved portion 13 is formed to have a length that extends from the attachment portion 21, through the other side of the wrist 100, to the palm side of the wrist 100 in a worn state in which the attachment portion 21 is disposed on the back side of the wrist 100.

[0019] For example, the first curved portion 12 and the second curved portion 13 are connected to each other via the attachment portion 21, and the opposite ends 12a, 12b form free ends that are spaced apart from each other. As an example, the first curved portion 12 is configured to be longer in the extension direction than the attached second curved portion 13. For example, when the band 10 is attached to the wrist 100, the first curved portion 12 is located on the hand 102 side in the longitudinal direction of the arm, and the second curved portion is located on the elbow side.

[0020] For example, in this embodiment, the first curved portion 12 and the second curved portion 13 each have end regions 12b, 13b of a predetermined length on the end portions 12a, 13a side, which overlap each other when viewed from the axial direction, for example. The end regions 12b, 13b at both ends of the band 10 are arranged at a predetermined distance apart in the axial direction, i.e., in the longitudinal direction of the arm 101 when worn. As an example, in this embodiment, the extension direction of the band 10 is constant over its entire length, and a predetermined curvature and inclination angle are set from one end to the other end. Therefore, the end regions 12b, 13b are arranged in parallel and spaced apart from each other when viewed from the side outside the curve. For example, the end region 12b of the first curved portion 12 and the end region 13b of the second curved portion 13 are arranged at a predetermined distance apart in the axial direction, forming an opening S1 through which the wearer passes between them.

[0021] For example, when viewed from the side, the pair of end regions 12b, 13b are inclined at a predetermined angle with respect to the longitudinal direction and extend parallel to each other.

[0022] For example, the dimensions of the band 10 are set based on the reference dimensions of the wrist 100 of the user who is expected to wear the band.

[0023] The inner diameter Φ1 of the spiral band 10 when viewed in the axial direction is set to a predetermined range corresponding to the reference diameter. The reference diameter is, for example, an estimated value of the wrist diameter (wrist width) of a Japanese person. Specifically, the wrist diameters on which the band 10 is supposed to be worn are grouped into a predetermined range, and the reference diameter is set based on the median value of the wrist diameter in the group. For example, the reference diameter of the band 10 is divided into two groups, male and female. For example, if the men's band is 57 mm and the women's band is 49 mm, the spiral diameter Φ1 is set within the range of 57 mm ± 8 mm for the men's band and within the range of 49 mm ± 7 mm for the women's band.

[0024] For example, the distance between the end regions 12b and 13b on both sides, that is, the width L1 of the opening S1 formed between the end regions 12b and 13b, is set within a predetermined range corresponding to the reference distance. For example, the opening width L1, which is the distance between the ends, is the minimum width dimension of the opening S1 formed between the ends of the overlapping band 10 as viewed from the axial direction. For example, when the reference distance is an estimated value of the side dimension (wrist thickness) of a Japanese person, with 40 mm for men and 35 mm for women, the opening width L1 is set within the range of 40 mm ± 7 mm for men and 35 mm ± 6 mm for women. That is, Φ1 and L1 are set according to the wrist for which wearing is assumed. Also, for example, L1 is set to a value larger than the assumed wrist thickness, smaller than the wrist width, and smaller than Φ1.

[0025] Also, the number of turns N, which is the number of turns of the band 10 wound in a spiral shape, is set such that 1.2 < N < 1.4. That is, the band 10 has a number of turns N from the end 12a to the end 13a that is more than 1.2 turns and less than 1.4 turns around the axis. For example, the circumferential distance of the overlapping end regions 12b and 13b where the end regions 12b and 13b on both sides overlap as viewed from the axial direction is 1 / 2 or less of the circumferential length, and is larger than 0.2 times and smaller than 0.4 times the length of one turn. For example, if the number of turns N is set to N ≤ 1.2, the wrist 100 is likely to slip out of the opening S1 and fall off easily. If N ≥ 1.4, it becomes difficult to wear the band 10 because the direction cannot be changed after inserting the wrist 100 into the band 10 without deforming the band 10.

[0026] The band thickness t1, which is the dimension in the thickness direction perpendicular or intersecting the spiral extension direction of the band 10, is set according to various conditions such as the required strength, and is, for example, 5 mm or more. Also, the band width w1, which is the dimension in the width direction perpendicular or intersecting the extension direction and the thickness direction, is set according to conditions such as the required strength, and is, for example, 15 mm or more. In addition, Φ1 and L1 are set according to the gender, average body type, and specifications of the person who is expected to wear the band. For example, the diameter of the band 10 is not limited to two groups, men's and women's, but may be grouped according to wrist thickness. Also, it may be set according to body types by country, such as for Japan and Europe and the United States. For example, the average value of the European and American specifications is set to the Japanese average value x 1.02 to 1.06.

[0027] As an example, the inner diameter Φ1 = 56 mm, the end-to-end distance (opening width) L1 = 42 mm, the number of rotations N = 1.25 mm, the band width w1 = 15 mm, and the band thickness t1 = 6 mm.

[0028] The device terminal 20 includes, for example, a case and various modules provided within the case. In the case of a wristwatch as an example, the device terminal 20 includes a watch case and a watch module housed within the watch case.

[0029] A method of attaching the wearable device 1 and band 10 of this embodiment to a target will be described below with reference to Figures 3(a) and (b). As an example, a wristwatch 1 is attached to a wrist 100, which is a part of an arm 101. For example, the wrist 100 is the end of the arm 101 on the hand 102 side, and has a shape in which a wrist thickness T0 perpendicular to the longitudinal direction of the arm 101 is smaller than a wrist width W0. In this embodiment, the end distance L1, which is the width of the opening S1, is formed to be larger than the wrist thickness T0.

[0030] In this embodiment, the band 10 can be worn on the wrist 100 by inserting the wrist 100 through the opening S1, and then changing the position after inserting the wrist 100 to change the relative relationship between the longitudinal direction and the axial direction of the arm 101.

[0031] Specifically, first, the wrist 100 is inserted from the side into the opening S1 between the end regions 12b and 13b with the arm 101 in a position where the longitudinal direction of the arm 101 is aligned with the extension direction of the end regions 12b and 13b. For example, at this time, the spiral axis C1 is inclined at a predetermined angle or more with respect to the longitudinal direction of the arm 101, and the wrist thickness T0 is positioned so as to be disposed within the opening width L1. Next, the wrist 100 and / or the wearable device 1 are twisted to change the relative angle between the arm 101 and the spiral axis C1, and the position is changed so that the inclination angle between the spiral axis C1 and the longitudinal direction of the arm 101 is smaller than that at the time of insertion. For example, the wrist 100 is in a position where the longitudinal direction of the wrist 100 is aligned with the axial direction of the spiral of the band 10, so that the band 10 is wrapped around the wrist 100. That is, after the wrist 100 is inserted from the outside to the inside of the curved portions 12, 13 with the wrist thickness T0 positioned within the opening S1, the wrist 100 and the wearable device 1 are shifted inside the band 10 to change their relative orientation, so that the longitudinal direction of the arm 101 of the wrist 100 inside the opening S1 is aligned in the same direction as the spiral axis C1. At this time, the direction of the wrist width W0 and the width direction of the opening S1 are aligned, so that the distance L1 which is the width of the opening S1 is smaller than the wrist width W0, and the extension direction of the end of the band 10 is inclined with respect to the length direction of the arm 101, so that the end of the band 10 interferes with the wrist 100, making it difficult for the wrist 100 to slip out of the opening S1, and thus preventing the band 10 from falling off.

[0032] Here, wrist thickness T0 of wrist 100 is smaller than wrist width W0, and inner diameter Φ1 of band 10 is set to match the wrist width, so band 10 is held in partial contact with wrist 100, and in other areas, gaps are formed between band 10 and the surface of wrist 100. Therefore, the band can be held in place with a loose fit.

[0033] Since the arm 101 becomes thicker from the wrist 100 side to the elbow side, the wearable device 1 can be arranged on the wrist 100 side in the longitudinal direction of the arm 101 when a looser fit is desired, and moved to the elbow side when a tighter fit is desired, thereby adjusting the fit, and for example, the position of the band 10 is fixed by the balance between the hard band 10 and the pressure of the arm. Also, even when moved to the elbow side to fit the second curved portion 13 side, the wrist side can maintain a loose fit without being tightly attached.

[0034] The watch band 10 and the watch 1 configured as above can provide a wearable device 1 that is easy to put on and take off, with a loose fit and prevention of slipping off. Therefore, the tendency to fall off can be suppressed to the extent that the band 10 does not come off unless the wrist 100 is actively bent. In addition, by setting the end-to-end distance L1, which is the opening width, and the number of turns N1, a structure that is easy to put on and difficult to fall off can be realized. That is, by making the band 10 out of a hard material and making the number of turns N1 greater than 1.2, it is possible to prevent the band 10 from falling off. On the other hand, if N1 is 1.4, it is a length that makes it difficult to put on because the direction cannot be changed after the arm 101 or wrist 100 is inserted, so by making the number of turns N1 smaller than 1.4, it is possible to smoothly change the direction, and it is possible to achieve both ease of wearing and difficulty in coming off. In addition, the fit can be adjusted by adjusting the position of the band 10 in the longitudinal direction of the arm 101. [Second embodiment] Hereinafter, the configuration and wearing method of the band 10A and the wearable device 1A according to the second embodiment will be described with reference to Figs. 4 to 7. Fig. 4 is a perspective view showing the configuration of the wearable device 1A. Fig. 5 is an explanatory diagram showing the configuration of the wearable device 1A, where (a) is a front view, (b) is a top view, (c) is a bottom view, and (d) and (e) are side views. Figs. 6(a), (b), and (c) are explanatory diagrams showing the wearing method of the wearable device 1A. Fig. 7 is a side view showing the state in which the wearable device 1A is worn on the wrist 100. Note that in each figure, the configuration is shown roughly by enlarging, reducing, or omitting as appropriate. In this embodiment, for example, the wearable device 1A will be described with the side facing the living body when worn as the back side and the side facing outward when worn as the front side. For example, the wearable device 1A is worn in a position in which the back side of the device (apparatus unit) 20 faces the surface of the wrist 100 to be worn.

[0035] The wearable device 1A according to this embodiment includes a band 10A and a device terminal 20. In this embodiment, the band 10A of the wearable device 1A is worn around the outer periphery of a wrist 100.

[0036] For example, the first curved portion 12 and the second curved portion 13 are connected to each other via the attachment portion 21, and the opposite ends form free ends that are spaced apart from each other. As an example, the first curved portion 12 is configured to be longer in the extension direction than the worn second curved portion 13. For example, in the worn state, the first curved portion 12 is arranged on the hand 102 side, and the second curved portion is arranged on the elbow side in the longitudinal direction of the arm 101.

[0037] In this embodiment, the band 10A of the wearable device 1A has different diameters of curved portions 12 and 13 depending on the location. In other words, the band 10A has a plurality of curvatures.

[0038] The band 10A has different radii of curvature between one end and the other end, and is configured such that, for example, the inner diameter Φ2 of the end region 13b of the second curved portion 13 arranged on the elbow side is larger than the inner diameter Φ1 of the end region 12b of the first curved portion arranged on the wrist side. For example, in this embodiment, in the middle part 12c of the first curved portion 12 on the hand 102 side from the attachment part 11, the curvature becomes smaller and the extension direction changes so that the inclination angle with respect to the axis becomes larger.

[0039] The inner diameter Φ2 of a region R1 from the end 13a of the second bending portion 13 through the attachment portion 11 to the middle portion 12c of the first bending portion 12 is configured to be larger than the inner diameter Φ1 of the end 12a of the first bending portion 12. For example, in this embodiment, the inner diameter Φ2 is the distance between two opposing portions in the first region R1. The inner diameter Φ1 is, for example, the diameter of an inscribed circle passing through the tip of the protrusion 14 provided on the inner surface of the end portion 12a of the band 10 and the opposing portion opposing the protrusion 14, i.e., the distance between the tip of the protrusion 14 and the opposing portion opposing the tip of the protrusion 14.

[0040] The first region R1 of the second curved portion and the first curved portion is curved along a circle having a predetermined radius of curvature when viewed from the axial direction, and extends in a spiral shape in a direction inclined at a predetermined angle with respect to the axial direction. On the other hand, the second region R2 on the tip side of the middle part 12c of the first curved portion 12 is curved along a circle having a predetermined radius of curvature when viewed from the axial direction, and extends in an arc shape perpendicular to the axial direction.

[0041] That is, band 10A has an arc-shaped portion that extends in an arc shape along the circumferential direction perpendicular to the axis, and the arc-shaped portion is formed over more than half the circumference in the circumferential direction, and the side edges of band 10 form a plane perpendicular to the axial direction.

[0042] The second region R2 of the first curved portion 12 of the band 10A extends in a circumferential direction perpendicular to the axial direction, and is disposed parallel to the width direction of the wrist 100 when viewed from the side of the wrist 100 when worn. For example, the angle of revolution of the second region R2, ie, the central angle of the second region, is set to, for example, 120 degrees or more. That is, one end side of the band 10B extends 120 degrees or more in a plane perpendicular to the axial direction.

[0043] The end region 12b of the first curved portion 12 of the band 10A has a tapered portion 12g in which the width of the tip gradually narrows toward the tip in the extension direction, for example, the side edge facing the second curved portion is closer to the side edge on the wrist side.

[0044] In addition, the inner surfaces of both ends 12a, 13a of the band 10B are formed with convex portions 14 that protrude toward the inside of the curve. For example, one or more convex portions 14 are formed on either one of the ends 12a, 13a.

[0045] For example, the dimensions of band 10A are set based on the reference dimensions of wrist 100 of the user who is expected to wear it.

[0046] The inner diameters Φ1 and Φ2 of the spiral band 10A when viewed in the axial direction are set in a predetermined range corresponding to the reference diameter. The reference diameter is, for example, an estimated value of the wrist diameter (wrist width) of a Japanese person. Specifically, the wrist diameters on which the band 10 is assumed to be worn are grouped in a predetermined range, and the reference diameter is set based on the median value of the wrist diameter in the group. For example, the reference diameter of the band 10A is divided into two groups, male and female. For example, if the diameter for men is 57 mm and the diameter for women is 49 mm, the spiral diameters Φ1 and Φ2 are set within the range of 57 mm ± 8 mm for men and 49 mm ± 7 mm for women. Φ2 is configured to be slightly larger than Φ1. For example, Φ2 = Φ1 + (2 to 4 mm).

[0047] For example, the distance between the end regions 12b and 13b on both sides, that is, the width L1 of the opening S1 formed between the end regions 12b and 13b, is set within a predetermined range corresponding to the reference distance. For example, the opening width L1, which is the distance between the ends, is the minimum width dimension of the opening S1 formed between the ends of the overlapping band 10A as viewed from the axial direction. For example, when the reference distance is an estimated value of the side dimension (wrist thickness) of a Japanese person, which is 40 mm for men and 35 mm for women, the opening width L1 is set within the range of 40 mm ± 7 mm for men and 35 mm ± 6 mm for women. That is, Φ1 and L1 are set according to the wrist for which wearing is assumed. Also, for example, L1 is set to a value larger than the assumed wrist thickness, smaller than the wrist width W0, and smaller than Φ1.

[0048] Also, the number of turns N, which is the number of turns of the band 10 wound in a spiral shape, is set such that 1.2 < N < 1.4. That is, the band 10 has a number of turns N from the end 12a to the end 13a that is more than 1.2 turns and less than 1.4 turns around the axis. For example, the circumferential distance of the overlapping end regions 12b and 13b where the end regions 12b and 13b on both sides overlap as viewed from the axial direction is 1 / 2 or less of the circumferential length, and is larger than 0.2 times and smaller than 0.4 times the length of one turn. For example, if the number of turns N is set to N ≤ 1.2, the wrist 100 is likely to slip out of the opening S1 and fall off, and if N ≥ 1.4, it becomes difficult to wear the band 10 because the direction cannot be changed after inserting the wrist 100 into the band 10 without deforming the band 10.

[0049] The band thickness t1, which is the dimension in the thickness direction orthogonal or intersecting the spiral extension direction of the band 10, is set according to various conditions such as the required strength, and is, for example, 5 mm or more. Also, the band width w1, which is the dimension in the width direction orthogonal or intersecting the extension direction and the thickness direction, is set according to conditions such as the required strength, and is, for example, 15 mm or more. In addition, Φ1, Φ2 and L1 are set according to the gender, average body type and specifications of the person who is expected to wear it. For example, the diameter of the band 10 is not limited to two groups, men's and women's, but may be grouped according to wrist thickness. Also, it may be set according to body types by country, such as for Japan and Europe and America. For example, the average value of the Europe and America specifications is set to the Japanese average value x 1.02 to 1.06.

[0050] As an example, the inner diameter Φ1 = 56 mm, the inner diameter Φ2 = Φ1 + (2 to 4 mm), the end distance (opening width) L1 = 42 mm, N = 1.25 mm, the wrist width W0 = 15 mm, and the band thickness t1 = 6 mm.

[0051] In this embodiment, the end region 12b of the first curved portion 12 of the band 10A has a tapered portion 12g in which the width of the tip gradually decreases toward the tip in the extension direction, for example, the side edge facing the second curved portion is closer to the side edge on the wrist side.

[0052] Furthermore, at each end of the band 10A, one or more anti-slip projections 14 are provided. The other configurations are similar to those of the wearable device 1 and the band 10 according to the first embodiment.

[0053] Hereinafter, a method of wearing the wearable device 1A and the band 10A in this embodiment on the wrist 100 to be worn will be described. In this embodiment, the end distance L1 is formed to be larger than the wrist thickness T0. Therefore, the longitudinal direction of the arm 101 is arranged in the opening between the end regions 12b, 13b along the extension direction of the end regions 12b, 13b, and the wrist 100 is inserted from the side. Next, the relative angle is changed while twisting either or both of the wrist 100 and the wearable device 1, for example, by taking a posture in which the longitudinal direction of the wrist 100 is along the axial direction of the spiral of the band 10, so that the band is wrapped around the wrist 100 one or more times. That is, after positioning the wrist thickness T0 so that it fits within the opening width and inserting the wrist 100 from the side, the relative positions of the wrist 100 and the wearable device 1 are changed, for example by about 90 degrees, inside the band 10 so that the direction of the wrist width W0, which is larger than L1, is aligned with the width direction of the opening inside the opening or is close to this, making it difficult for the wrist to slip out of the opening and preventing it from falling off.

[0054] According to the wearable device 1A and the band 10A of the present embodiment, by configuring the device to have multiple curvatures, it is possible to make one of the regions fit the arm, and to create a space between the arm and the other region. That is, since there is a difference in curvature depending on the part, there are parts that fit the wrist 100 and parts that float from the wrist 100. Therefore, the fixation of the band 10A is ensured at the parts that fit, while the loose fit of the band 10A is ensured at the parts that do not fit, and it is possible to realize the conflicting demands of "loose fit" and "suppression of active positional displacement of the functional part". In addition, for example, since the diameter of the human arm 101 is smaller on the wrist side than on the elbow side, it is possible to improve the fit by providing a difference in curvature in both directions.

[0055] In addition, the wearable device 1A and band 10A have a convex portion 14 that protrudes inward at the end, and the diameter of the inscribed circle passing through the convex portion 14 is smaller than the inner diameter of the band 10A, so that fixation at the convex portion 14 is possible and a loose fit can be easily ensured in other areas.

[0056] In addition, the band 10A according to the above embodiment is configured so that the end region 12b of the first curved portion 12 on the wrist side extends in a direction perpendicular to the axis, making it easy to hold the band 10 on the wrist 100. Furthermore, the wrist-side end region 12b of the band 10A has an acute angle, which makes it easy to lightly catch on bones and muscles on the underside of the wrist, thereby preventing the band from being displaced, such as by actively rotating or dropping into the palm. Therefore, it is possible to easily put on and take off devices such as wristwatches and wristwatch-type wearable devices on the arm, and to keep the fluctuation within a certain range while realizing a loose fit. Also, the band 10A can be freely fixed between the wrist and the elbow by balancing the pressure between the band and the flesh, and the fit can be adjusted.

[0057] In the second embodiment, for example, the arc-shaped portion is not limited to being perpendicular to the axial direction, but may be inclined, and the inclination angle relative to the axial direction of the end on the wrist side is smaller than that of the end on the elbow side, thereby improving holding ability.

[0058] [Third embodiment] Hereinafter, the configuration and wearing method of the band 10B and the wearable device 1B according to the third embodiment will be described with reference to Figs. 8 to 10. Fig. 8 is an explanatory diagram showing the configuration of the wearable device 1A, where (a) is a front view, (b) is a top view, (c) is a bottom view, and (d) and (e) are side views. Figs. 9(a), (b) and (c) are explanatory diagrams showing a wearing method of the wearable device 1A. Fig. 10 is an explanatory diagram showing another usage mode of the wearable device 1A. Note that in each figure, the configuration is shown in outline by appropriately enlarging, reducing and omitting. In this embodiment, for example, the wearable device 1B will be described with the side facing the living body when worn as the back side and the side facing outward when worn as the front side. For example, the wearable device 1B is worn in a position where the back side of the device (apparatus unit) 20 faces the wrist 100 to be worn.

[0059] The wearable device 1B according to this embodiment includes a band 10B and a device terminal 20. In this embodiment, the wearable device 1B is worn by wrapping the band 10 around the outer periphery of a wrist 100, which is a target for wearing the band 10 and has a different dimension in one direction from that in another direction intersecting or perpendicular to the one direction. In the wearable device 1B, the device terminal 20 is rotatably or movably connected to one end of the band 10. In this embodiment, the part on the wrist side is described as a first curved part 12, and the part on the elbow side is described as a second curved part 13. For example, in this embodiment, an example is shown in which the attachment part 11 to which the device terminal 20 is attached in the band 10 is provided at the end of the second curved part 13.

[0060] For example, the band 10B has free ends spaced apart from each other. For example, when worn, the first curved portion 12 on one end side is disposed on the hand side, and the second curved portion is disposed on the elbow side in the longitudinal direction of the arm.

[0061] In this embodiment, the band 10B of the wearable device 1B has a curved portion with different diameters depending on the location, and has a plurality of curvatures.

[0062] The band 10B has different radii of curvature between one end and the other end. For example, the inner diameter Φ2 of the end 13a of the second curved portion 13 arranged on the elbow side is larger than the inner diameter Φ1 of the end 12a of the first curved portion 12 arranged on the wrist side. Specifically, a small diameter portion 17 is formed on the tip side of the first curved portion 12 arranged on the wrist side, and the base end side of the first curved portion 12 and the second curved portion 13 form a large diameter portion 18. The inner diameter Φ2 of the region R1 from the end 13a of the second curved portion 13 to the middle portion 12c of the first curved portion 12 through the attachment portion 11 is larger than the inner diameter Φ1 of the region R2 of the end region 12b from the middle portion 12c of the first curved portion 12 to the end 12a. For example, in this embodiment, the extension direction changes so that the curvature becomes smaller and the inclination angle with respect to the axis becomes larger in the middle portion 12c of the first curved portion 12 on the hand 102 side. In this embodiment, the inner diameter Φ1 is, for example, the diameter of an inscribed circle passing through the end 12a of the band 10 on the wrist side and a portion opposite to the end 12a.

[0063] The second curved portion 13 and the first region R1 of the first curved portion 12 are curved along a circle having a predetermined inner diameter Φ2 when viewed from the axial direction, and extend spirally in a direction inclined at a predetermined angle to the axial direction. On the other hand, the second region R2 on the tip side of the middle portion 12c of the first curved portion 12 is curved along a circle having a predetermined inner diameter Φ1 when viewed from the axial direction, and extends in an arc shape perpendicular to the axial direction.

[0064] The end region 12b of the first curved portion 12 of the band 10B has a tapered portion 12g in which the width of the tip gradually decreases toward the tip in the extension direction, for example, the side edge facing the second curved portion is closer to the side edge on the wrist side.

[0065] The second region R2 of the first curved portion 12 of the band 10B extends in a circumferential direction perpendicular to the axial direction, and is arranged parallel to the width direction of the wrist 100 when viewed from the side of the wrist 100 when worn. That is, the extension direction of the second region R2 is configured to have a larger inclination angle with respect to the axial direction than the extension direction of the first region R1. For example, the rotation angle of the second region R2 is 120° or more. That is, one end side of the band 10B has an arc-shaped portion that extends in an arc shape along the circumferential direction perpendicular to the helical axis C1, and the arc-shaped portion is formed over 1 / 3 or more of the circumference in the circumferential direction.

[0066] For example, the dimensions of the band 10B are set based on the reference dimensions of the wrist 100 of the user who is expected to wear the band.

[0067] The inner diameter Φ of the spiral band 10B when viewed in the axial direction is set to a predetermined range corresponding to the reference diameter. The reference diameter is, for example, an estimated value of the wrist diameter (wrist width) of a Japanese person. Specifically, the wrist diameters on which the band 10 is assumed to be worn are grouped into a predetermined range, and the reference diameter is set based on the median value of the wrist diameter in the group. For example, the reference diameter of the band 10A is divided into two groups, male and female. For example, if the diameter for men is 57 mm and the diameter for women is 49 mm, the spiral diameter Φ is set within the range of 57 mm ± 8 mm for men and 49 mm ± 7 mm for women. Φ2 is configured to be slightly larger than Φ1. For example, Φ2 = Φ1 + (2 to 4 mm).

[0068] For example, the distance between the end regions 12b and 13b on both sides, i.e., the width L1 of the opening S1 formed between the end regions 12b and 13b, is set to a predetermined range corresponding to the reference distance. For example, the opening width L1, which is the distance between the ends, is the minimum width dimension of the opening S1 formed between the ends of the band 10A that overlap when viewed from the axial direction. For example, the reference distance is an estimated value of the side dimension of the wrist (wrist thickness) of Japanese people, and when the reference distance is 40 mm for men and 35 mm for women, the opening width L1 is set within the range of 40 mm ± 7 mm for men and 35 mm ± 6 mm for women. That is, Φ1 and L1 are set according to the wrist that is expected to be worn. Also, for example, L1 is set to a value larger than the expected wrist thickness and smaller than the wrist width, and is set to a value smaller than Φ1.

[0069] Also, the number of turns N of the spiral winding of the band 10 is set such that 1.2 < N < 1.4. That is, for the band 10, the number of turns N from the end 12a to the end 13a is more than 1.2 turns and less than 1.4 turns around the axis. For example, the circumferential distance of the overlapping end regions 12b, 13b where the end regions 12b, 13b on both sides overlap when viewed axially is 1 / 2 or less of the circumferential length, greater than 0.2 times and less than 0.4 times the length of one turn. For example, if the number of turns N is set to N ≤ 1.2, the wrist 100 can easily slip out and fall off from the opening S1. If N ≥ 1.4, it becomes difficult to attach the band 10 because the direction cannot be changed after inserting the wrist 100 unless the band 10 is deformed.

[0070] The band thickness t1, which is the dimension in the thickness direction perpendicular or intersecting the spiral extension direction of the band 10, is set according to various conditions such as the required strength, and is, for example, 5 mm or more. Also, the band width w1, which is the dimension in the width direction perpendicular or intersecting the extension direction and the thickness direction, is set according to conditions such as the required strength, and is, for example, 15 mm or more. Note that Φ1, Φ2, and L1 are set according to the gender, average body size, and specifications of the human assumed as the wearing object. For example, the diameter of the band 10 is not limited to two groups for men and women, and may be grouped by wrist thickness. Also, it may be set according to the body size by country, such as for Japan and for Europe and America. For example, the average value of the European and American specifications is set to 1.02 - 1.06 times the Japanese average value.

[0071] As an example, the inner diameter Φ1 = 56 mm, the inner diameter Φ2 = Φ1 + (2 - 4 mm), the end - to - end distance (opening width) L1 = 42 mm, the number of turns N = 1.25 mm, the band width w1 = 15 mm, and the band thickness t1 = 6 mm.

[0072] Also, in the wearable device 1B, the device terminal 20 is rotatably connected to the band 10. Specifically, the device terminal 20 is rotatably connected to the end 13a of the band 10 of the wearable device 1B via the movable part 31.

[0073] For example, the movable part 31 includes a connection hole 13e formed in the end 13a of the second curved part 13 which is on the elbow side of the band 10B, an attachment part 21 having an attachment hole 21a provided in the device terminal 20, and an axial member 32 which serves as a connecting member for rotatably connecting the device terminal 20 to the end 13a.

[0074] In the movable part 31, the mounting part 21 and the end part 13a of the device terminal 20 are arranged in a stacked manner in the band thickness direction perpendicular to the extension direction of the band 10B and the width direction of the band 10B, and are rotatably connected by an axis member 32 that passes through the mounting hole 21a and the connection hole 13e.

[0075] Therefore, the wearable device 1B is configured such that the position of the device terminal 20 is variable and the state can be changed between a first state and a second state depending on the position of the device terminal 20. For example, the first state is an open state in which the device terminal 20 is disposed at a position away from the opening S1 between the ends 12a and 13a, and the second state is a closed state in which the device terminal 20 is disposed in at least a part of the opening S1 between the ends 12a and 13a.

[0076] Hereinafter, a method of wearing the wearable device 1B and the band 10B in this embodiment on the wrist 100 to be worn will be described. First, before wearing, the device terminal 20 is placed at a position outside the opening S1 to be in an open state (first state). Then, the arm 101 is placed in the opening between the end regions 12b, 13b so that the longitudinal direction of the arm 101 is along the extension direction of the end regions 12b, 13b, and the wrist 100 is inserted from the side. Next, the relative angle is changed while twisting either or both of the wrist 100 and the wearable device 1, for example, to a position where the longitudinal direction of the wrist 100 is along the axial direction of the spiral of the band 10. As a result, the band is wrapped around the wrist 100 one or more times. That is, after inserting the wrist 100 from the side with the wrist thickness T0 positioned within the opening width, the wrist 100 and the wearable device 1 are relatively turned, for example, by about 90 degrees, inside the band 10, so that the direction of the wrist width W0, which is larger than the end-to-end distance L1, which is the opening width, is aligned with or close to the width direction of the opening inside the opening, making it difficult for the wrist to slip out of the opening. Furthermore, the movable part 31 is turned in the opposite direction to close the opening S1, thereby completing the wearing process.

[0077] The other configurations are similar to those of the wearable devices 1, 1A and the bands 10, 10A according to the first and second embodiments.

[0078] The wearable device 1B and the band 10B according to this embodiment also have the same effects as the wearable device 1, 1A and the band 10, 10A according to the first and second embodiments. In addition, the device terminal 20 having a movable part is arranged in the wearable device 1B and the band 10B, so that the opening S1 can be opened and closed by the device terminal 20. Therefore, the conflicting requirements of "loose wearing" of the terminal worn on the wristwatch or the arm and "fixed position of the band" can be simultaneously satisfied, and "falling off" during wearing can be suppressed. In addition, in the wearable device 1B and the band 10B, the second region R2 arranged in a plane perpendicular to the axis is secured to have a central angle of 120° or more, so that the band 10 can be made to stand on its own. For example, as shown in FIG. 11, the band 10B can be used by standing stably on a stand.

[0079] The present invention is not limited to the above-mentioned embodiment. For example, in the above-mentioned example, the protrusions are provided on the ends 12a and 12b, but the present invention is not limited to this. As another embodiment, as shown in Fig. 11 and Fig. 12, the inner surface of the end of the curved part may have a protrusion 15 protruding toward the inside of the curve, and for example, the extension direction may change to face inward at the ends 12a and 13a. For example, in this embodiment, Φ1 = 42 mm, L1 = 32 mm, N = 1.25, w = 12 mm, t = 6 mm, and the face diameter, which is the inner diameter of the end protruding inward: 38 mm.

[0080] The object to be worn is not limited to the wrist 100 or the arm 101, but may be another part such as the ankle. For example, the object to be worn may be the wrist or the ankle, the dimension in one direction may be the wrist thickness or the ankle thickness, and the dimension in the other direction may be the wrist width or the ankle width. The device terminal 20 is not limited to a watch, but may be applied to various devices such as switches and sensors. The device terminal 20 may not be joined to the band 10, and a part of the device terminal 20 may constitute a part of the band 10. For example, the device terminal 20 such as a display unit may be integrally formed in the middle of a single band. For example, the device terminal 20 may be provided at the end of the band 10, not at the center of the band 10 in the extension direction. A plurality of device terminals 20 may be provided.

[0081] In the second and third embodiments, examples were shown in which the bands 10A, 10B have different curvatures on one side and the other side around a predetermined base point in the extension direction, but this is not limited to this, and the bands may have three or more different curvatures, or may be partially straight. Also, examples were shown in which all or most of the bands are spiral, but this is not limited to this. For example, most of the bands may be arc-shaped, and only a portion may be spirally shaped inclined toward the axial direction. In the second and third embodiments, examples have been shown in which the convex portions 14 are formed at the ends of the bands 10A, 10B, but the present invention is not limited to this, and the bands 10A, 10B may have a configuration in which the convex portions 14 are not provided. In the band 10B according to the third embodiment, a part of the movable portion 31 may function as a protrusion that protrudes inward.

[0082] In addition, in the second embodiment, the inner diameter Φ1 on the wrist side is the diameter of the inscribed circle at the tip of the convex portion 14, but this is not limited to this. For example, the inner diameter Φ1 may be the inner diameter at a portion other than the convex portion 14. In addition, in the second embodiment, the inner diameter Φ2 of the end portion 13b arranged on the elbow side is based on the inner diameter at a portion other than the convex portion 14, but the inscribed circle at the tip of the convex portion 14 may be the inner diameter Φ2. In the second embodiment, the radius of curvature on the wrist side is made smaller and the protrusions 14 are formed on both ends, but this is not limiting. For example, the radius of curvature may be constant and a protrusion may be formed only on one end side that is on the wrist side. In the second and third embodiments, the radius of curvature and the extension direction are changed, but the present invention is not limited to this. For example, the radius of curvature as viewed from the axial direction may be constant, and the extension direction of the wrist side region may be configured to have a larger inclination angle with respect to the axial direction than the extension direction of the opposite region, and to be aligned with the wrist width direction. In the second and third embodiments, the portion extending in the plane perpendicular to the axis has a central angle of 120° or more, but this is not limited thereto. For example, the portion may extend over half a circumference with a central angle of 180° or more.

[0083] In the third embodiment, the opening S1 is opened and closed by the equipment terminal 20, but the opening S1 may be opened and closed by other means such as a gate.

[0084] In the above embodiment, the band 10 is made of a hard material such as hard resin, metal, stone, wood, and ceramic. However, the material is not limited to these materials. Hard materials include hard springs. The width of the opening of the hard spring does not change. The hard spring maintains its shape when worn and when being worn, and always ensures an opening width for the wrist to pass through. Even before being worn, the spring does not elastically deform and the width of the opening does not change.

[0085] Although several embodiments of the present invention have been described, the present invention is included in the scope of the invention described in the claims and its equivalents. Note that the present invention is not limited to the above-mentioned embodiments, and various modifications can be made in the implementation stage without departing from the gist of the present invention.
