[0012] (First Embodiment)

[0013] Hereinafter, a first embodiment of the present invention will be described based on the drawings. Figure 1 The watch 10 shown has: a case 3, which has a display part 31 arranged on the visible side (front side) and is made of metal or hard resin; an exterior component 5, which is arranged on the front side of the case 3 and is made of metal or hard resin; a strap 2, which is installed on the case 3; and a fixing component 6, which is arranged on the back side of the case 3 and fixes the exterior component 5 to the case 3. The exterior device 80 includes the exterior component 5 and the fixing component 6. The display part 31 of the watch 10 can display information such as time, date, and day of the week. A watch glass is provided on the display part 31. In addition, the time display of the display part 31 can be in various forms such as analog or digital, and in the first embodiment, it is digital. In addition, the exterior component 5 can also use components of other materials such as soft resin materials such as polyurethane resin. In the following description, the upper side (that is, when the watch 10 is worn on the wrist and observed from the visible side) will be referred to. Figure 1 The upper side of the wrist is set as the upper side, the lower side is set as the lower side, the left side is set as the left, and the right side is set as the right. In addition, the visible side is also referred to as the front side, and the opposite side (wrist side) is referred to as the rear side or the back side.

[0014] The strap 2 of the watch 10 is connected by inserting a locking pin 22 provided on the other strap 2 into one of the holes 21 of the strap 2. The strap 2 of one side is attached to the lower side of the case 3, and the strap 2 of the other side is attached to the upper side.

[0015] The housing 3 is formed into a bottomed cylindrical shape that is slightly elongated in the left-right direction (the direction perpendicular to the band 2) when viewed from the visible side. Figure 4 As shown, a watch module 8 is provided inside the case 3. The watch module 8 includes various components required for watch functions, such as a circuit unit that is electrically driven in order to display information such as the time on the display unit 31. The case 3 includes a cylindrical case body 32 and a roughly plate-shaped back cover 33 at the bottom of the case 3. The back cover 33 includes: a bulging portion 331 that bulges in a circular shape on the side opposite to the visible side, i.e., the rear side of the watch 10; and a flange portion 332 formed on the outer periphery of the bulging portion 331. As shown in FIG. Figure 2As shown, the back cover 33 has a rectangular plate-shaped portion 333 further extending from the flange portion 332 toward each band 2. Near the corner of the rectangular plate-shaped portion 333, a hole portion (not shown) for inserting a bolt 35 for connecting the back cover 33 to the case body 32 is provided.

[0016] On the left and right sides of the housing 3, there are provided two buttons 7, a total of four buttons, as operating bodies. Various settings and operations related to clock functions, stopwatches, etc. can be performed through the buttons 7. In addition, the operating body can also be formed as a dragon head instead of the button 7 according to the display form of the watch 10, etc.

[0017] In addition, if Figure 3 As shown in FIG. 1 , a band mounting portion 34 is provided on the upper and lower sides of the housing 3. The band mounting portion 34 is formed in a substantially bifurcated shape and protrudes from the housing body 32 toward the direction of the watch band 2. Figure 4 As shown, a spring bar 323 is provided on the band mounting portion 34 so as to be detachably inserted into the band 2. The band 2 is provided so as to be detachably attached by the spring bar 323. In addition, the spring bar 323 can use a known spring bar 323 having a slide bar 324.

[0018] The end of the band 2 mounted on the band mounting portion 34 is integrally provided with a rotation stopper 25. The rotation stopper 25 contacts the upper surface of the rectangular plate-shaped portion 333 of the back cover 33 corresponding to the band mounting portion 34, thereby preventing the band 2 from rotating toward the back cover 33 side about an imaginary axis extending in the width direction of the band 2. Therefore, it is possible to prevent a gap from being generated between the band 2 and the case 3 on the front side due to the band 2 falling toward the back cover 33 side.

[0019] Furthermore, the end 221 of the rotation-stopping portion 25 is formed in a straight line in the width direction (left-right direction) of the watch band 2. The end 221 contacts the edge of the circular bulge 331 in a tangential manner. A recess 26 is provided on the outer side of the rotation-stopping portion 25 (specifically, the upper side of the rotation-stopping portion 25 in the upper rotation-stopping portion 25 and the lower side of the rotation-stopping portion 25 in the lower rotation-stopping portion 25) of each watch band 2, into which a fixing member 6 described later is inserted. Therefore, the fixing member 6 is provided on the outer side of the rotation-stopping portion 25. In addition, at the end of each watch band 2 at a position corresponding to the sliding rod 324 of the spring rod 323, a rectangular opening 212 is provided at a position on the outer side of the rotation-stopping portion 25, i.e., at a position overlapping with the recess 26, through which the sliding rod 324 of the spring rod 323 is exposed.

[0020] like Figure 3As shown, the outer casing 5 is formed with a hole portion 51 of a roughly horizontally long octagonal shape in the center of the front side for exposing the display portion 31. The outer casing 5 is also formed in a roughly horizontally long octagonal shape in cooperation with the housing 3 in its outer shape. Specifically, the outer casing 5 has: a front side wall portion 510, which partially covers the front side of the housing 3; and a side side wall portion 520, which is continuous with the front side wall portion 510 and covers the side of the housing 3 in the left-right direction. A covering portion 530 connected to the side side wall portion 520 and the front side wall portion 510 and covering the belt mounting portion 34 is formed above and below the outer casing 5. In addition, the side side wall portion 520 includes a first side side wall portion 521 and a second side side wall portion 522, which respectively cover one side of a pair of side surfaces in the left-right direction of the housing 3, namely the left side, and the other side, namely the right side.

[0021] The outer member 5 is mounted on the housing 3 in such a manner as to cover the housing 3 from the front side. The button 7 protruding from the housing 3 avoids interference with the outer member 5 by means of an operating body arrangement portion 523 formed by cutting into a U-shape on the side wall portion 520 of the outer member 5. In addition, when the outer member 5 is mounted on the housing 3, the outer member 5 is guided by engaging the guide portion 322 protruding from the side in the left-right direction of the belt mounting portion 34 with the concave guided portion 531 provided on the cover portion 530 of the outer member 5. In addition, by adjusting the gap by forming the guide portion 322 and the guided portion 531 into a tapered shape or the like, the engagement of the outer member 5 with the housing 3 can be made to be slightly fixed (to the extent that it can be easily removed by hand). Alternatively, a click feeling can be given by the engagement of the concave and convex.

[0022] like Figure 1 The enlarged view of the P part, Figure 2 As shown, the latched portion 55 is provided on the outer side of the left and right side wall portions 520 (the first side wall portion 521 and the second side wall portion 522) of the exterior member 5. The first latched portion 55a is provided on the left side of the latched portion 55, and the second latched portion 55b is provided on the right side. The latched portion 55 is provided between two operating body configuration portions 523, 523 (buttons 7, 7) on each side in the left and right directions. Figure 1As shown in the enlarged view of the P part, two protrusions 551 and 552 are provided on the locked part 55, and the two protrusions 551 and 552 are arranged in the up-down direction of the side surface in the left-right direction of the outer casing 5. A groove 553 is provided between the two protrusions 551 and 552. The protrusions 551 and 552 are formed in a hook shape, and inclined surfaces 551a and 552a are formed. The inclined surfaces 551a and 552a are inclined surfaces that are inclined in a direction extending outward from the rear side toward the front side. A bearing surface step portion 554 is formed at a position opposite to the visible side of the protrusions 551 and 552, that is, the locked surfaces 551b and 552b. The bottom surface 553a of the groove portion 553 is orthogonal to the bearing surface 554a of the bearing surface step portion 554. In addition, the locked portion 55 may be provided on an edge surface on the back side of the lateral side wall portion 520 (ie, an end portion on the opposite side to the front side wall portion 510 ).

[0023] like Figure 3 As shown, the fixing member 6 performs wire forming processing on a metal linear member such as a wire, and forms a ring shape by welding with a welding portion 62. The locking portion 61 of the fixing member 6, which is formed into a substantially rectangular shape in side view, is arranged at two opposite locations, and the locking portion 61 on the left side is set as a first locking portion 611, and the locking portion 61 on the right side is set as a second locking portion 612. Each locking portion 61 protrudes in a substantially U-shaped shape in side view toward the axial direction of the ring. A groove locking portion 63 formed in a straight line is provided in the fixing member 6 in a direction orthogonal to each locking portion 61. Both ends of the straight line groove locking portion 63 are connected to the bending portion 64, and are further connected to the locking portion 61 via a circular arc portion 65 convex in the outward direction. Elastic force can be generated in the first locking portion 611 and the second locking portion 612 arranged opposite to each other. That is, when the first locking portion 611 and the second locking portion 612 are deformed in the direction of separation, elastic force in the direction of approaching the first locking portion 611 and the second locking portion 612 is generated. In addition, the first locking portion 611 and the second locking portion 612 are connected to each other through two connecting portions 66 composed of a groove locking portion 63, two curved portions 64 connected to both ends of the groove locking portion 63, and arc-shaped portions 65 connected to each curved portion 64.

[0024] like Figure 1 As shown in the enlarged view of the P portion of the fixing member 6, the fixing member 6 is provided with a linear portion 61a of the fixing portion 61 between the fixing surfaces 551b and 552b of the protrusions 551 and 552 of the fixing portion 55 and the receiving surface 554a of the receiving surface step portion 554, and the fixing portion 61 is fixed to the fixing portion 55. Specifically, as shown in FIG. Figure 2As shown, the first locking portion 611 is locked with the first locked portion 55a, and the second locking portion 612 is locked with the second locked portion 55b. In addition, the groove locking portion 63 of the fixing component 6 is embedded in and locked with the recessed portion 26 of the anti-rotation portion 25. In addition, the curved portion 64 of the fixing component 6 is arranged along the outer edge of the rectangular plate-shaped portion 333 of the rear cover 33. Similarly, the arc-shaped portion 65 of the fixing component 6 is arranged along the outer edge of the flange portion 332 of the rear cover 33. In this way, the fixing component 6 is arranged along the outer periphery of the rear cover 33. That is, the fixing component 6 is arranged in a manner that does not overlap with the rear cover 33 when viewed from above (when viewed from the rear side). In other words, the portion other than the locking portion 61 of the fixing component 6, that is, the connecting portion 66, is arranged on the rear side of the shell body 32 along the outer periphery of the rear cover 33.

[0025] In addition, the arc-shaped portion 65 and a part of the curved portion 64 of the fixing member 6 are arranged on the edge surface of the rear side of the housing body 32. Furthermore, the height from the edge surface of the rear side of the housing body 32 to the fixing member 6 arranged on the edge surface is lower than the height from the edge surface to the outer surface of the bulging portion 331 of the rear cover 33. In other words, Figure 2 In the range L inside the end 221 of the opposed anti-rotation portion 25 shown in the figure (i.e., the range L inside the tangent line of the upper and lower sides of the back cover 33), the portion other than the locking portion 61 of the fixing member 6 (in this embodiment, the entire fixing member 6 including the locking portion 61 of the fixing member 6) is arranged on the front side of the outer surface of the back cover 33. In addition, when the wristwatch 10 is worn on the wrist, the range in the up-down direction is set as the range L, and the left-right direction is set as the lateral width of the case 3. In addition, there is a case where the fixing member 6 does not abut the edge surface on the rear side of the case body 32.

[0026] In terms of mounting the fixing member 6, the fixing member 6 is pressed in by aligning the locking portion 61 with the locked portion 55 from the rear side of the housing 3 to which the exterior member 5 is mounted. Then, the linear portion 61a of the locking portion 61 slides on the inclined surfaces 551a and 552a of the protrusions 551 and 552 of the locked portion 55, and the first locking portion 611 and the second locking portion 612 expand in a manner of separating from each other in the left-right direction, and the linear portion 61a of the locking portion 61 is arranged between the locked surfaces 551b and 552b of the protrusions 551 and 552 and the receiving surface 554a of the receiving surface step portion 554. At this time, the fixing member 6 is arranged in a manner that the first locking portion 611 and the second locking portion 612 expand in the direction of separation and are locked with the first locked portion 55a and the second locked portion 55b. That is, the fixing member 6 is formed such that the space between the first locking portion 611 and the second locking portion 612 is slightly narrower than the space between the first locked portion 55a and the second locked portion 55b (and the left and right locked surfaces 551b and 552b). Figure 5 As shown in (b), Figure 5 The state of the fixing component 6 shown in (a) is assembled in a state where the whole is deformed into a convex bending shape toward the side of the exterior component 5. Therefore, while the locking portion 61 of the fixing component 6 is locked on the locked portion 55, the convexly curved portion of the fixing component 6 (specifically, the arc-shaped portion 65) presses the back side of the shell 3 (the edge surface on the back side of the shell body 32), and the elastic force of the fixing component 6 in the thickness direction of the shell 3 acts on the exterior component 5. Therefore, the exterior component 5 is strongly pushed toward the back direction relative to the shell 3. In this way, the exterior component 5 is fixed to the shell 3, so the exterior component 5 is fixed not only with respect to the thickness direction of the shell 3, but also with respect to the up and down direction and the left and right direction. In addition, Figure 5 (b) shows the bending state in an exaggerated manner for the sake of understanding. In addition, the straight portion 61a of the locking portion 61 is located inside the side surface 554b of the receiving surface step portion 554. Therefore, the straight portion 61a of the locking portion 61 will not be caught on the protrusions 551 and 552 to cause the fixing member 6 to fall off.

[0027] As for removing the fixing member 6, Figure 6 As shown in (a), the front end of the clamp 90 formed into a flat head screwdriver shape is inserted into the groove 553 of the locked portion 55, and the front end of the clamp 90 is hung on the straight portion 61a of the locking portion 61. Figure 6 As shown in (b), if the straight portion 61a of the locking portion 61 is expanded outward by the clamp 90, the locking portion 61 falls off from the protrusions 551 and 552, and the fixing member 6 can be removed. In addition, if the outer casing 5 is removed from the housing 3, replaced with another outer casing 5 and the fixing member 6 is installed again, the outer casing 5 can be replaced.

[0028] (Second Embodiment)

[0029] Next, based on Figure 7 (a) and (b) of the present invention are described below. In the watch 10A of the second embodiment of the present invention, a fixing member 6A having a connecting portion 66A composed of a rubber band connecting a first locking portion 611A and a second locking portion 612A is formed instead of the annular fixing member 6 of the first embodiment. The structure of the watch 10A other than the fixing member 6A, such as the case 3, the exterior member 5, and the band 2, is the same as that of the watch 10 of the first embodiment. Therefore, their description is omitted or simplified.

[0030] like Figure 7As shown in (a), the fixing member 6A has two long rectangular ring-shaped locking portions 61A. In addition, a connecting portion 66 is provided across the first locking portion 611A and the second locking portion 612A respectively arranged on the left and right as the locking portions 61A. In the fixing member 6A, when the first locking portion 611A and the second locking portion 612A are moved in the direction of separation, the first locking portion 611A and the second locking portion 612A are forced in the direction of approaching.

[0031] As for the installation of the fixing member 6A, the locking portion 61A is locked with the locked portion 55 from the rear side of the housing 3. Specifically, the linear portion 61aA of the locking portion 61A is arranged between the locked surfaces 551b, 552b of the protrusions 551, 552 and the receiving surface 554a of the receiving surface step portion 554. At this time, since the locking portions 61A are arranged in a manner extending in the direction of separation from each other, the linear portion 61aA of the locking portion 61A is reliably arranged between the locked surfaces 551b, 552b and the receiving surface 554a. In this way, since the locking portion 61A is locked with the locked portion 55, the outer casing 5 is pushed against the housing 3, and the movement of the outer casing 5 in the up-down direction and the left-right direction is also restricted together with the movement of the outer casing 5 in the thickness direction of the housing 3. Therefore, the outer casing 5 is fixed to the housing 3.

[0032] In addition, when removing the fixing member 6A, the clamp 90 (see Figure 6 (a) and (b) to remove it.

[0033] (Variant 1)

[0034] based on Figure 8 A modification 1 of the above embodiment will be described. In this modification 1, a spacer may be provided between the front side wall portion 510 of the exterior member 5 and a portion (surface) of the housing 3 that faces the front side wall portion 510. Figure 8 The buffer member 511 is shown as the hatched line. The buffer member 511 is respectively arranged at the four corners of the upper, lower, left and right sides of the front side wall portion 510. The buffer member 511 can be fixedly arranged on at least one of the exterior component 5 or the shell 3. In addition, the buffer member 511 can be a member having elastic force such as a member made of polyurethane rubber or foam material of a predetermined thickness. In addition, at this time, the rigidity of the exterior component 5 is composed of a material having a rigidity greater than that of the shell 3. By configuring the buffer member 511 in this way, when the exterior component 5 is pushed against the shell 3 by the fixing components 6, 6A, the buffer member 511 is compressed, and the shaking of the exterior component 5 relative to the shell 3 in the thickness direction of the shell 3 and in the up and down, left and right directions can be further suppressed.

[0035] According to the above embodiment, the watch 10 with the exterior device 80 includes: the exterior component 5, which has a front side wall portion 510 partially covering the front side of the case 3 of the watch 10, a side side wall portion 520 covering the side of the case 3 in the left and right direction, and a locked portion 55 provided on the side side wall portion 520; and a fixing component 6, which has a locking portion 61, which is provided on the rear side of the case 3, and the exterior component 5 is fixed to the case 3 by the locking portion 61 being locked to the locked portion 55. As a result, the exterior component 5 can be easily replaced, and the fixing component 6 that fixes the exterior component 5 can be set so as not to appear on the visible side (especially on the front side of the watch glass of the display unit 31). Therefore, it is possible to reduce the possibility that the fixing component 6 is caught on something during the wearing of the watch 10, thereby causing the exterior component 5 to fall off accidentally. In addition, since the fixing component 6 can be made invisible from the visible side, the degree of freedom of the appearance design of the watch can also be improved.

[0036] In addition, the side wall portion 520 includes a first side wall portion 521 and a second side wall portion 522 that respectively cover one side and the other side of a pair of side surfaces in the left-right direction of the housing 3, and the locked portion 55 includes a first locked portion 55a and a second locked portion 55b that are respectively provided on the first side wall portion 521 and the second side wall portion 522, and the fixing member 6 has a first locking portion 611 and a second locking portion 612 as a locking portion 61 that are respectively locked on the first locked portion 55a and the second locked portion 55b, and a connecting portion 66 that connects the first locking portion 611 and the second locking portion 612. Thus, the exterior member 5 can be reliably locked to the housing 3 at two locations on the left and right, and the first locking portion 611 and the second locking portion 612 can be formed integrally by the connecting portion 66, which can be a fixing member that is easy to handle.

[0037] In addition, the housing 3 includes a housing body 32 on the front side and a rear cover 33, and a portion of the fixing member 6 other than the locking portion 61 is provided on the housing body 32 along the outer periphery of the rear cover 33. Thus, the fixing member 6 can be arranged to avoid the rear cover 33 in a manner including the bolts 35 connecting the rear cover 33 and the housing body 32, so that even when the rear cover 33 needs to be removed for maintenance such as battery replacement, the fixing member 6 can be removed without removing the rear cover 33.

[0038] In addition, when the watch 10 is worn on the wrist, the back cover 33 contacts the wrist, and within the range where the back cover 33 contacts the wrist, the portion other than the locking portion 61 of the fixing member is arranged on the front side of the case 3 relative to the outer surface of the back cover 33. As a result, the fixing member 6 provided on the case body 32 does not protrude from the back cover 33, and when the watch 10 is fitted on the wrist, the back cover 33 contacts the wrist more frequently, which can suppress the contact between the fixing member 6 and the wrist.

[0039] In addition, the case 3 is provided with a watch band 2 having a rotation stopper 25, and the rotation stopper 25 contacts the rear side of the case 3 to prevent the watch band 2 from rotating toward the rear cover 33 about an imaginary axis extending in the width direction of the watch band 2, and a recess 26 is formed in the rotation stopper 25, and the fixing member 6 engages with the recess of the rotation stopper 25. Thus, the rotation of the watch band 2 can be reliably restricted by the rotation stopper 25 without being affected by the fixing member 6.

[0040] In addition, the case body 32 includes a guide portion 322 that engages with the guided portion 531 of the exterior member 5 to guide the exterior member 5. This facilitates attachment of the exterior member 5 to the case body 32 of the case 3.

[0041] In addition, the locked portion 55 includes a plurality of protrusions 551, 552 arranged in the vertical direction of the side wall portion 520, the locking portion 61 is locked to the plurality of protrusions 551, 552, and a groove portion 553 is provided between the plurality of protrusions 551, 552 for guiding the clamp 90 for releasing the locking of the locking portion 61 to the plurality of protrusions 551, 552. Thus, the fixing member 6 can be easily removed using the clamp 90.

[0042] In addition, a plurality of buttons 7, 7 are arranged in the vertical direction of the side surface of the case 3 in the horizontal direction, and the locked portion 55 is arranged between the buttons 7, 7 as the plurality of operating bodies. Thus, even on the side surface of the watch 10 that is sometimes seen, the locked portion 55 and the locking portion 61 can be arranged in an orderly manner, and the operation of each button 7 will not be hindered.

[0043] In addition, the exterior member 5 has the operation body placement portion 523 cut into a U-shape so as not to interfere with the buttons 7, 7. Thus, the exterior member 5 can be mounted on the housing 3 including the buttons 7.

[0044] Furthermore, the housing 3 is provided with the guide portion 322, and the exterior member 5 has the guided portion 531 engaged with the guide portion 322, and the exterior member 5 is guided by the engagement of the guided portion 531 with the guide portion 322. Thus, the exterior member 5 can be smoothly attached and detached.

[0045] In addition, the exterior member 5 is made of a material having a higher rigidity than the housing 3, and a buffer 511 is arranged between the front side wall portion 510 and the housing 3. In addition, the buffer 511 is provided at least on one of the exterior member 5 and the housing 3. Thus, the shaking of the exterior member 5 relative to the housing 3 is further suppressed.

[0046] In addition, the fixing member 6 is formed into a ring shape by a linear member. Thus, the fixing member 6 can be formed to be difficult to see from the outside. However, the fixing member 6 can be not only a linear member, but also a combination of prisms and cylinders or a block.

[0047] In addition, the embodiments described above are presented as examples and are not intended to limit the scope of the invention. These new embodiments can be implemented in various other ways, and various omissions, substitutions, and changes can be made without departing from the scope of the subject matter of the invention. These embodiments and their variations are included in the scope or subject matter of the invention, and are included in the invention described in the claims and their equivalents.
