[0010] (First Embodiment)

[0011] Below, refer to Figure 1 to Figure 3 , a first embodiment applied to a wristwatch is described.

[0012] like Figure 1 to Figure 3 As shown in FIG. 1 , the wristwatch includes a watch case 1 . The watch case 1 includes a case member 2 and a cover member 3 . The case member 2 includes a main case 4 and an outer case 5 .

[0013] like Figure 2 and Figure 3 As shown, the main body shell 4 is made of metal or hard synthetic resin, for example, a hard synthetic resin with high rigidity obtained by mixing carbon fiber or glass fiber into polyamide resin, preferably a hard synthetic resin with high rigidity obtained by mixing carbon fiber into polyamide resin. The main body shell 4 is formed into a roughly annular shape, and has a metal reinforcement portion 4a embedded in the interior of the upper side thereof.

[0014] like Figure 2 and Figure 3 As shown, a watch glass 6 is mounted on the upper opening of the main body case 4 via a glass gasket 6a, and an annular partition member 7 is arranged in the main body case 4 below the watch glass 6. In addition, a back cover 8 is mounted on the lower part of the main body case 4 via a waterproof ring 8a and a plurality of first screws 8b. In this case, a plurality of first screw insertion holes 8c for inserting the plurality of first screws 8b are respectively provided on the back cover 8.

[0015] like Figure 2 and Figure 3 As shown, a watch module 10 is arranged inside the main body case 4 via a buffer sheet 9. The watch module 10 includes a watch movement (not shown) that moves a pointer 11 to indicate the time, a display unit (not shown) that electro-optically displays information such as time and date, a circuit substrate 12 that drives and controls them, and a battery 13 that supplies power to the circuit substrate 12, and other various electronic components required for the watch function.

[0016] In addition, if Figure 1 and Figure 2 As shown in the figure, the main body housing 4 is provided with button mounting parts 15 of the button switch 14 at the 2 o'clock side, the 4 o'clock side, the 6 o'clock side, the 8 o'clock side, and the 10 o'clock side of the outer periphery. These plurality of button mounting parts 15 respectively include: a cylindrical part 15a protruding to the outside of the main body housing 4; and a through hole 15b located at the center of the cylindrical part 15a and penetrating the inside and outside of the main body housing 4.

[0017] In this case, if Figure 2 As shown, the push button switch 14 includes: an operating shaft 14a slidably inserted into the through hole 15b; and a button head 14b provided at the outer end of the operating shaft 14a and arranged in the cylindrical portion 15a. Thus, the push button switch 14 is configured such that when the button head 14b is pressed from the outside of the main body case 4, the operating shaft 14a slides in the through hole 15b, and the inner end of the operating shaft 14a is pressed into the main body case 4, and the pressed inner end of the operating shaft 14a presses the contact portion (not shown) of the watch module 10 to perform a switch action.

[0018] On the other hand, Figure 1 to Figure 3As shown, the outer shell 5 is formed of a soft synthetic resin such as polyurethane resin into a ring shape covering the upper outer periphery of the main shell 4. The outer shell 5 is attached to the upper part of the main shell 4 by a double-sided tape 16 in a state of covering the upper outer periphery of the main shell 4. On the outer periphery of the outer shell 5, a plurality of first notch portions 5a in an arc shape are provided corresponding to the outer periphery of the upper side of each cylindrical portion 15a of the plurality of button mounting portions 15 of the main shell 4.

[0019] In this case, if Figure 2 As shown in the figure, the plurality of first notches 5a are each formed in an arc shape with the lower side open. Thus, the outer casing 5 is configured so that when it is arranged on the upper outer periphery of the main casing 4, the outer periphery of the upper side of each cylindrical portion 15a of the plurality of button mounting portions 15 of the main casing 4 is arranged in the plurality of first notches 5a. In addition, a plurality of decorative sheets 5b are provided on the upper surface of the outer casing 5.

[0020] In addition, if Figure 1 to Figure 3 As shown, the cover component 3 includes a cover main body 17 arranged on the back side, i.e., the lower surface, of the back cover 8, an outer peripheral cover portion 18 arranged on the outer periphery of the main shell 4, and a belt mounting portion 19 provided on the 12 o'clock side and the 6 o'clock side of the outer peripheral cover portion 18, which are integrally formed of synthetic resin.

[0021] That is, Figure 1 to Figure 3 As shown, the cover member 3 is formed of a hard synthetic resin, for example, a hard synthetic resin with high rigidity obtained by mixing carbon fiber or glass fiber into polyamide resin, preferably a hard synthetic resin with high rigidity obtained by mixing glass fiber into polyamide resin. The cover body 17 of the cover member 3 is formed in a disc shape and is configured to be mounted on the back cover 8 by a plurality of second screws 20.

[0022] That is, Figure 2 and Figure 3 As shown, the cover body 17 is provided with a plurality of second screw insertion holes 17a for inserting the plurality of second screws 20 via the plurality of annular buffer bodies 21. The plurality of buffer bodies 21 are configured so that when the threaded portions 20a of the plurality of second screws 20 are inserted and screwed into the back cover 8, the heads 20b of the plurality of second screws 20 abut against the lower surface of the cover body 17.

[0023] In this case, if Figure 2 and Figure 3 As shown, the back cover 8 is provided with a plurality of threaded holes 8d for screwing in the plurality of second screws 20 corresponding to the plurality of second screw insertion holes 17a of the cover body 17. Thus, the cover body 17 is configured to be installed on the back cover 8 by inserting the plurality of second screws 20 through the annular buffer body 21 into the plurality of second screw insertion holes 17a and screwing into the plurality of threaded holes 8d of the back cover 8 to be fastened.

[0024] like Figure 2 As shown, the outer peripheral cover portion 18 is provided on the outer periphery of the cover body 17, covers the outer periphery of the main housing 4, and is formed into a substantially annular shape. A plurality of second notch portions 18a in the shape of an arc are provided on the outer periphery of the lower side of each cylindrical portion 15a of the plurality of button mounting portions 15 of the main housing 4.

[0025] Therefore, if Figure 2 As shown, the outer peripheral cover part 18 is configured so that when it is arranged on the outer periphery of the main body case 4, the outer periphery of the lower side of each cylindrical part 15a of the plurality of button mounting parts 15 of the main body case 4 is respectively inserted into the plurality of second notch parts 18a. In this case, the outer peripheral cover part 18 is configured to be arranged close to or in contact with the lower end of the outer peripheral side of the outer casing 5 whose upper end is mounted on the upper outer periphery of the main body case 4.

[0026] In addition, if Figure 3 As shown, the peripheral cover portion 18 can also be configured so that when the cover body 17 is installed on the lower surface of the back cover 8 and is configured on the periphery of the main shell 4, the inner peripheral surface of the peripheral cover portion 18 and the outer peripheral surface of the main shell 4 are close to or in contact with each other. In addition, it can also be configured so that there is a gap between the inner peripheral surface of the peripheral cover portion 18 and the outer peripheral surface of the main shell 4 that is the same as the gap S1 between the belt mounting portion 19 described later and the main shell 4 (not shown).

[0027] Therefore, if Figure 3 As shown, the peripheral cover portion 18 is configured so that when the cover body 17 is mounted on the lower surface of the back cover 8 and arranged on the outer periphery of the main body case 4, when the watch case 1 is impacted from the outside, the impact is buffered by the peripheral cover portion 18. In this case, the peripheral cover portion 18 is preferably configured so that it is flexed and deformed in a manner close to the outer peripheral surface of the main body case 4 through the gap between its inner peripheral surface and the outer peripheral surface of the main body case 4, thereby buffering the impact.

[0028] On the other hand, Figure 1 and Figure 2 As shown, the band attachment portion 19 is used to attach the watch band 23 to the 12 o'clock side and the 6 o'clock side of the watch case 1, and includes a pair of attachment protrusions 24 and a band receiving portion 25. The pair of attachment protrusions 24 protrude from the outer peripheral cover portion 18 obliquely downward.

[0029] In this case, if Figure 1 and Figure 2 As shown, the pair of mounting protrusions 24 are inclined obliquely downward so that the inner end surface on the main body case 4 side is arranged close to the outer peripheral surface of the main body case 4 and the lower part on the outer end side is located below the lower surface of the cover body 17.

[0030] In addition, if Figure 3As shown, a pair of mounting protrusions 24 have a gap S1 between the inner end surface on the main body housing 4 side and the outer peripheral surface of the main body housing 4. The gap S1 is used to allow the pair of mounting protrusions 24 to bend and deform in a manner such that the inner ends of the pair of mounting protrusions 24 approach the outer peripheral surface of the main body housing 4 when the pair of mounting protrusions 24 are impacted from the lower side.

[0031] In addition, if Figure 3 As shown, the pair of mounting protrusions 24 are configured to approach or contact the lower end of the outer peripheral portion of the outer casing 5 whose upper end portion on the inner end side is provided on the upper outer periphery of the main casing 4. Thus, the pair of mounting protrusions 24 are configured so that the lower portions of the outer ends thereof are pushed upward and deformed in a manner such that the pair of mounting protrusions 24 are pushed upward, thereby flexing and deforming in a manner such that the inner ends of the pair of mounting protrusions 24 approach the outer peripheral surface of the main casing 4.

[0032] In addition, if Figure 1 and Figure 2 As shown, the band mounting portion 19 is configured such that the end of the band 23 is rotatably mounted via a connecting pin 26 when the end of the band 23 is disposed between a pair of mounting protrusions 24. That is, a pair of mounting holes 24a for inserting and mounting the two ends of the connecting pin 26 are provided on the same axis in correspondence with each other in the pair of mounting protrusions 24.

[0033] In this case, if Figure 2 As shown, the connecting pin 26 is a spring rod, and is constructed so that by being inserted into a pin insertion hole 23a provided at the end of the strap 23, both ends protrude outward from the pin insertion hole 23a, and the protruding two ends can be inserted into each mounting hole 24a of a pair of mounting protrusions 24 so as to be retractable, thereby being rotatably installed in a state where the end of the strap 23 is arranged between a pair of mounting protrusions 24.

[0034] like Figure 2 As shown, the band receiving portion 25 is used to block the lower surface of the end of the band 23 arranged between the pair of mounting protrusions 24, and is inclined downward like the pair of mounting protrusions 24 at the lower part between the pair of mounting protrusions 24.

[0035] In this case, if Figure 2 As shown, the band receiving portion 25 is formed so that the length of the long side direction of the band 23 is shorter than the protruding length of the pair of mounting protrusions 24. Therefore, the band 23 is configured to rotate around the connecting pin 26 while being mounted between the pair of mounting protrusions 24 through the connecting pin 26.

[0036] Therefore, if Figure 2As shown, the band mounting portion 19 is constructed such that a connecting pin 26 serving as a spring rod is preliminarily inserted into a pin insertion hole 23a at the end of the strap 23, and when both ends of the connecting pin 26 are arranged between a pair of mounting protrusions 24 in a state of protruding from both sides of the pin insertion hole 23a, the two ends of the protruding connecting pin 26 are pressed into the interior of the connecting pin 26, thereby arranging the end of the strap 23 between the pair of mounting protrusions 24.

[0037] In addition, if Figure 2 As shown, the band mounting portion 19 is configured such that when both ends of the connecting pin 26 are pushed in and the end of the watch band 23 is arranged between the pair of mounting protrusions 24, the lower surface of the end of the watch band 23 abuts against the band receiving portion 25, and in this state, both ends of the connecting pin 26 are correspondingly inserted into the respective mounting holes 24a of the pair of mounting protrusions 24. Thus, the end of the watch band 23 is rotatably mounted on the band mounting portion 19.

[0038] Therefore, if Figure 2 and Figure 3 As shown, the belt mounting portion 19 is constructed so that when the watch case 1 falls from the back side and abuts against a contact surface T such as a floor, the lower outer ends of a pair of mounting protrusions 24 protruding toward the lower side of the cover body 17 abut against the contact surface T, so that the lower outer ends of the pair of mounting protrusions 24 are pushed upward, and the pair of mounting protrusions 24 are deformed in a manner of being pushed upward, and the inner ends of the pair of mounting protrusions 24 are flexed and deformed in a manner of approaching the outer peripheral surface of the main shell 4 to cushion the impact.

[0039] Next, the function of such a wristwatch will be described.

[0040] When assembling the wristwatch, first, the case member 2 is assembled. At this time, the annular partition member 7 is first arranged at the upper opening of the main case 4, and in this state, the watch glass 6 and the glass gasket 6a are installed together, and the partition member 7 is pressed and fixed in the main case 4 through the watch glass 6.

[0041] In this state, the outer case 5 is mounted on the upper outer periphery of the main case 4 by means of the double-sided tape 16. At this time, the arc-shaped first notches 5a provided in the outer case 5 are made to correspond to the outer peripheries of the upper sides of the cylindrical parts 15a of the button mounting parts 15 of the main case 4, and the outer peripheries of the upper sides of the cylindrical parts 15a are arranged in the first notches 5a. Thus, the case member 2 is assembled.

[0042] Then, the watch module 10 is inserted into the main body case 4 from the lower side and stored therein. In this state, a plurality of push button switches 14 are respectively mounted on a plurality of button mounting portions 15 provided at the 2 o'clock side, the 4 o'clock side, the 6 o'clock side, the 8 o'clock side, and the 10 o'clock side of the outer periphery of the main body case 4.

[0043] At this time, the operating shafts 14a of the multiple button switches 14 are inserted from the outside of the main body shell 4 through the cylindrical parts 15a of the multiple button mounting parts 15 into the through holes 15b of the main body shell 4, and the button heads 14b of the multiple button switches 14 are respectively arranged in the cylindrical parts 15a of the multiple button mounting parts 15.

[0044] Then, the inner end of each operating shaft 14a of the plurality of button switches 14 is pressed into the main body case 4, and corresponds to the plurality of contact portions (not shown) of the watch module 10 in the main body case 4. Thus, the plurality of button switches 14 are respectively mounted on the plurality of button mounting portions 15 of the main body case 4 in a state where the plurality of contact portions of the watch module 10 can be switched.

[0045] After that, a buffer sheet 9 is arranged on the lower side of the watch module 10, and the back cover 8 and the waterproof ring 8a are mounted on the lower surface of the main body case 4 together with a plurality of first screws 8b. At this time, the plurality of first screws 8b are respectively inserted into the plurality of first screw insertion holes 8c of the back cover 8, and are screwed in and fastened to the lower part of the main body case 4. Thus, the back cover 8 is mounted on the lower surface of the main body case 4.

[0046] Then, the cover member 3 is mounted on the lower surface of the back cover 8. In this case, the cover body 17 of the cover member 3 is arranged on the lower surface of the back cover 8, the peripheral cover portion 18 corresponds to the outer periphery of the main body case 4, and the belt mounting portion 19 is arranged on the 12 o'clock side and the 6 o'clock side of the main body case 4 accordingly.

[0047] At this time, the multiple second notch portions 18a provided in the outer peripheral cover portion 18 are made to correspond to the lower measured outer circumferences of each cylindrical portion 15a of the multiple button mounting portions 15 of the main shell 4, and the outer circumferences of the lower sides of each cylindrical portion 15a of the multiple button mounting portions 15 are respectively inserted and arranged in these multiple second notch portions 18a.

[0048] Thus, the outer peripheral surface of the main body case 4 and the inner peripheral surface of the outer peripheral cover portion 18 are arranged close to or in contact with each other, or the outer peripheral surface of the main body case 4 and the inner peripheral surface of the outer peripheral cover portion 18 are arranged with a gap (not shown) the same as the gap S1 of the belt mounting portion 19. In addition, in this state, the upper end of the outer peripheral cover portion 18 is arranged close to or in contact with the lower end of the outer peripheral side of the outer case 5 mounted on the upper outer periphery of the main body case 4. Therefore, the outer periphery of the main body case 4 is covered by the outer periphery of the outer case 5 and the outer peripheral cover portion 18 of the cover member 3.

[0049] In addition, at this time, the belt mounting portion 19 is arranged corresponding to the outer peripheral surface of the 12 o'clock side and the 6 o'clock side of the main body case 4. In this case, a gap S1 is provided between the inner end surface of the pair of mounting protrusions 24 of the belt mounting portion 19 and the outer peripheral surface of the main body case 4, and the upper end portions of the inner end side of the pair of mounting protrusions 24 are arranged close to or in contact with the lower end portion of the outer peripheral side of the outer casing 5 mounted on the upper outer periphery of the main body case 4.

[0050] Then, the second screw insertion holes 17a provided in the cover body 17 are aligned with the threaded holes 8d provided in the back cover 8. In this state, the second screws 20 are respectively inserted into the annular buffer bodies 21, and the buffer bodies 21 are respectively attached to the second screws 20.

[0051] At this time, the plurality of second screws 20 with the plurality of buffer bodies 21 installed thereon are respectively inserted into the plurality of second screw insertion holes 17a of the cover body 17 and screwed into the plurality of threaded holes 8d of the back cover 8. Thus, the plurality of buffer bodies 21 are elastically pressed to the lower surface of the cover body 17 of the cover member 3 by the heads 20b of the plurality of second screws 20, and the cover member 3 is installed on the lower surface of the back cover 8 in this state.

[0052] In this case, the watch case 1 is assembled in a state where the back cover 8 on the lower surface of the main shell is covered by the cover body 17, the upper periphery of the main shell 4 is covered by the outer shell 5, and the outer periphery of the main shell 4 is covered by the outer periphery of the outer shell 5 and the outer peripheral cover part 18 of the cover part 3.

[0053] After that, the watch band 23 is mounted on the band mounting portion 19 of the cover member 3. At this time, first, the connecting pin 26 is inserted into the pin insertion hole 23a at the end of the watch band 23, and both ends of the connecting pin 26 protrude from both sides of the pin insertion hole 23a. When arranged between the pair of mounting protrusions 24 in this state, both ends of the protruding connecting pin 26 are pressed into the inside of the connecting pin 26, so that the end of the watch band 23 is arranged between the pair of mounting protrusions 24.

[0054] At this time, the lower surface of the end of the strap 23 disposed between the pair of mounting protrusions 24 is disposed on the strap receiving portion 25, and the two ends of the connecting pin 26 correspond to the pair of mounting holes 24a provided in the pair of mounting protrusions 24. Then, the two ends of the connecting pin 26 are pushed out from both sides of the end of the strap 23 and inserted into the pair of mounting holes 24a. Thus, the end of the strap 23 is rotatably mounted on the strap mounting portion 19 of the cover member 3, and the wristwatch is assembled.

[0055] In such a wristwatch, the cover member 3 covers the outer periphery of the case member 2 and is mounted on the lower surface of the back cover 8, so when the case 1 is impacted from the outside, the impact is buffered by the cover member 3. Therefore, the case member 2 is well protected by the cover member 3, so the impact resistance is improved.

[0056] That is, when the watch case 1 is impacted from the back side, the cover member 3 can protect the back cover 8 and the main case 4 from the impact on the back side through the cover body 17 disposed on the lower surface of the back cover 8. In addition, when the watch case 1 is impacted from the peripheral side, the peripheral cover portion 18 and the belt mounting portion 19 disposed on the peripheral portion of the outer case 5 and the peripheral portion of the main case 4 can protect the main case 4 from the impact from the peripheral side.

[0057] In this case, when the wristwatch falls from the back side and abuts against a contact surface T such as a floor, the lower outer ends of the pair of mounting protrusions 24 of the band mounting portion 19 of the cover member 3 abut against the abutment surface T, and the band mounting portion 19 is impacted. At this time, the pair of mounting protrusions 24 of the band mounting portion 19 are flexed and deformed in such a way that the inner ends thereof approach the outer peripheral surface of the main body case 4, thereby absorbing the impact.

[0058] That is, a gap S1 is provided between each inner end surface of a pair of mounting protrusions 24 with the mounting portion 19 and the outer peripheral surface of the main body shell 4, and the upper end portion of each inner end side of the pair of mounting protrusions 24 is arranged close to or in contact with the lower end portion of the outer peripheral side of the outer shell 5 mounted on the upper outer periphery of the main body shell 4. Therefore, if each outer end lower portion of the pair of mounting protrusions 24 with the mounting portion 19 abuts against the abutment surface T, each outer end lower portion of the pair of mounting protrusions 24 is pushed upward.

[0059] Therefore, the pair of mounting protrusions 24 with the mounting portion 19 are bent and deformed in a direction approaching the outer peripheral surface of the main body case 4 with the lower portion of the outer peripheral cover portion 18 located at the outer peripheral portion of the cover body 17 as a fulcrum. Thus, the pair of mounting protrusions 24 are deformed to approach the outer peripheral surface of the main body case 4 by respective bending deformation, so that the impact caused by the fall of the watch case 1 is alleviated. Therefore, the watch module 10 in the watch case 1 can be protected from the impact.

[0060] In this case, a pair of mounting protrusions 24 are deformed by their flexural deformation in a manner approaching the outer peripheral surface of the main shell 4. When the cover body 17 of the cover part 3 abuts against the abutment surface T, the impact is buffered by the multiple buffer portions 21 on the lower surface of the back cover 8 against which the heads 20b of the multiple second screws 20 abut.

[0061] In addition, when the watch case 1 is impacted from above, the outer shell 5 provided on the upper outer periphery of the main shell 4 is formed of a soft synthetic resin such as polyurethane resin, so that the impact from above is buffered by the outer shell 5, thereby preventing the main shell 4 from being directly impacted from above.

[0062] Thus, according to the wristwatch, a case part 2 is provided with a back cover 8 mounted on the lower surface serving as the back, and a cover part 3 is mounted on the lower surface of the cover 8 and covers the outer periphery of the case part 2 and is provided with a belt mounting portion 19 corresponding to the outer periphery of the case part 2, thereby providing a wristwatch with high impact resistance.

[0063] That is, in this wristwatch, the cover part 3 covers the outer periphery of the shell part 2 and is installed on the lower surface of the back cover 8. Therefore, even if the watch case 1 is impacted from the outside, the impact can be cushioned by the cover part 3, thereby enabling the shell part 2 to be well protected by the cover part 3, thereby providing a wristwatch with high impact resistance.

[0064] In this case, in the wristwatch, a gap S1 is provided between the outer peripheral surface of the shell component 2 and the inner end portion of the corresponding band mounting portion 19 of the cover component 3, whereby when the watch case 1 is impacted from the outside, the band mounting portion 19 can be well deformed toward the outer peripheral surface of the shell component 2 through the gap S1 between the outer peripheral surface of the shell component 2 and the inner end surface of the band mounting portion 19, thereby enabling the impact on the watch case 1 to be well cushioned by the band mounting portion 19 of the cover component 3.

[0065] In addition, in this wristwatch, the case part 2 includes a hard main body case 4 and a soft outer case 5 arranged on the upper outer periphery of the main body case 4. Thus, when the watch case 1 is impacted from above, the impact can be cushioned by the soft outer case 5. Therefore, the hard main body case 4 can be well protected by the soft outer case 5, thereby ensuring impact resistance.

[0066] In addition, in this wristwatch, a gap S1 is provided between the outer peripheral surface of the main body case 4 and the inner end surface of the corresponding band mounting portion 19 of the cover component 3, that is, the inner end surfaces of a pair of mounting protrusions 24 of the band mounting portion 19. Thus, when the watch case 1 is impacted from the outside, the pair of mounting protrusions 24 of the band mounting portion 19 can be deformed toward the outer peripheral surface of the case component 2 through the gap S1 between the outer peripheral surface of the case component 2 and the inner end surfaces of the pair of mounting protrusions 24. Therefore, the impact received by the watch case 1 can be reliably and well buffered by the band mounting portion 19.

[0067] In this case, in the wristwatch, the lower outer ends of a pair of mounting protrusions 24 of the belt mounting portion 19 of the cover part 3 are arranged to protrude to the lower side than the lower surface of the cover body 17 of the cover part 3, whereby the watch case 1 falls from the back side and the lower outer ends of the pair of mounting protrusions 24 abut against a contact surface T such as a floor, thereby enabling the lower outer ends of the pair of mounting protrusions 24 to be deformed in an upward pushing manner.

[0068] Therefore, in this watch, a pair of mounting protrusions 24 can be bent and deformed in such a way that the inner ends of a pair of mounting protrusions 24 pushed up by the impact caused by falling approach the outer peripheral surface of the shell part 2, so that the impact received by the watch case 1 due to falling can be reliably and well cushioned through the belt mounting part 19.

[0069] In addition, in this wristwatch, the lower end portion of the outer peripheral side of the outer shell 5 is arranged close to or in contact with the upper ends of a pair of mounting protrusions 24 of the belt mounting portion 19 of the cover member 3. As a result, when the watch case 1 is subjected to an impact caused by falling, the pair of mounting protrusions 24 of the belt mounting portion 19 can be reliably and well deformed toward the outer peripheral surface of the case member 2 without being hindered by the outer shell 5, and the impact received by the watch case 1 due to falling can be reliably and well cushioned by the belt mounting portion 19.

[0070] Furthermore, in the wristwatch, the cover member 3 is mounted on the back cover 8 via the plurality of buffer bodies 21 by the plurality of second screws 20, so that when the cover member 3 is impacted from the back side, the impact can be buffered by the plurality of buffer bodies 21. That is, when the cover body 17 of the cover member 3 abuts against the abutment surface T, the impact can be well buffered by the plurality of buffer portions 21 abutted against the lower surface of the back cover 8 by the heads 20b of the plurality of second screws 20.

[0071] (Second Embodiment)

[0072] Next, refer to Figure 4 , a second embodiment applied to a wristwatch is described. Figure 1 to Figure 3 The same components as those in the first embodiment are denoted by the same reference numerals as those described above.

[0073] like Figure 4 As shown in FIG. 1 , the outer case 30 of the wristwatch has a structure different from that of the first embodiment, but other than that, the structure is substantially the same as that of the first embodiment.

[0074] That is, Figure 4 As shown, the outer case 30 is formed into an annular shape by a soft synthetic resin such as polyurethane resin as in the first embodiment. In this case, the outer case 30 is attached to the upper part of the main case 4 by a double-sided tape 16 so as to cover the upper outer periphery of the main case 4.

[0075] In the outer periphery of the outer casing 30, as in the first embodiment, a plurality of first notches 5a are provided corresponding to the outer peripheries of the upper sides of the cylindrical portions 15a of the plurality of button mounting portions 15 of the main casing 4. These plurality of first notches 5a are each formed into an arc shape open to the lower side. Thus, the outer casing 30 is configured such that, when arranged on the upper outer periphery of the main casing 4, the outer peripheries of the upper sides of the cylindrical portions 15a of the plurality of button mounting portions 15 of the main casing 4 are respectively arranged in the plurality of first notches 5a.

[0076] In addition, if Figure 4 As shown, the length of the outer peripheral portion of at least the portion corresponding to the belt mounting portion 19 in the upper peripheral portion of the outer peripheral portion of the outer casing 30 covering the outer peripheral portion of the main casing 4 in the vertical direction is formed to be longer than the length of the outer peripheral portion of the outer casing 5 of the first embodiment in the vertical direction. Thus, the outer casing 30 is configured to be arranged in a state where the lower end portion of the outer peripheral side is sandwiched between the inner end portion of the belt mounting portion 19 and the main casing 4.

[0077] That is, Figure 4 As shown, the outer casing 30 is configured in a state where the lower end of the outer peripheral side of the outer casing 30 is sunk into the upper side of the gap S1 provided between the inner end of the pair of mounting protrusions 24 of the belt mounting portion 19 and the outer peripheral surface of the main casing 4. In this case, a space of the gap S1 is provided below the lower end of the outer peripheral side of the outer casing 30.

[0078] In such a wristwatch, as in the first embodiment, the cover member 3 covers the outer periphery of the case member 2 and is mounted on the lower surface of the back cover 8, so when the watch case 1 is impacted from the outside, the impact is buffered by the cover member 3. Therefore, the case member 2 is well protected by the cover member 3, and thus the impact resistance is improved.

[0079] That is, the cover member 3 is similar to the first embodiment, and when the watch case 1 is impacted from the back side, the cover body 17 disposed on the lower surface of the back cover 8 can protect the back cover 8 and the main case 4 from the impact on the back side. In addition, when the watch case 1 is impacted from the peripheral side, the peripheral cover portion 18 and the belt mounting portion 19 disposed on the peripheral portion of the outer case 5 and the peripheral portion of the main case 4 can protect the main case 4 from the impact on the peripheral side.

[0080] In this case, when the watch falls from the back side and the lower outer ends of a pair of mounting protrusions 24 of the belt mounting portion 19 of the cover part 3 abut against an abutment surface T such as a floor, due to the impact caused by the fall, the lower outer ends of the pair of mounting protrusions 24 abut against the abutment surface T and are pushed upward, and the pair of mounting protrusions 24 are bent and deformed in such a way that the inner ends of the pair of mounting protrusions 24 approach the outer peripheral surface of the main body case 4.

[0081] At this time, the lower end portion of the outer peripheral side of the outer shell 30 is arranged in a state of being sandwiched by being sunk into the upper side of the gap S1 between the inner ends of a pair of mounting protrusions 24 provided on the belt mounting portion 19 and the outer peripheral surface of the main shell 4, and a space of the gap S1 is provided on the lower side of the lower end portion of the outer peripheral side of the outer shell 30. Therefore, the pair of mounting protrusions 24 are bent and deformed in a direction approaching the outer peripheral surface of the main shell 4 with the lower portion of the outer peripheral cover portion 18 located on the outer peripheral portion of the cover body 17 as a fulcrum.

[0082] That is, the outer shell 30 is formed of a soft synthetic resin such as polyurethane resin, and the lower end of the outer peripheral side of the outer shell 30 is clamped between the inner end of the outer peripheral cover part 18 of the cover part 3 and the outer peripheral surface of the main shell 4. Therefore, the impact caused by the falling of the watch case 1 is buffered by the elastic force of the lower end of the outer peripheral side of the outer shell 30, so that the watch module 10 in the watch case 1 can be affected by the impact.

[0083] In this way, according to this wristwatch, in addition to having the same effects as those of the first embodiment, the lower end portion of the outer peripheral portion of the outer shell 30 is arranged in a sunken state on the upper side of the gap S1 provided between the outer peripheral surface of the main shell 4 and the inner end surface of the belt mounting portion 19 of the cover part 3, so that the impact caused by the falling of the watch case 1 can be buffered by the lower end portion of the outer peripheral side of the outer shell 30.

[0084] That is, in this wristwatch, the outer case 30 is formed of a soft synthetic resin such as polyurethane resin, and the lower end portion of the outer peripheral side of the outer case 30 is clamped between the upper end portions of the inner end sides of a pair of mounting protrusions 24 of the belt mounting portion 19 and the outer peripheral surface of the case body 4. Therefore, the impact caused by the fall of the watch case 1 can be buffered by the lower end portion of the outer peripheral side of the outer case 30, thereby preventing the watch module 10 in the watch case 1 from being affected by the impact, thereby improving the impact resistance.

[0085] In addition, in the above-mentioned second embodiment, a situation is described in which the lower end portion of the outer peripheral side of the outer shell 30 is configured to be embedded in the upper side of the gap S1 between the inner end portions of a pair of mounting protrusions 24 provided on the belt mounting portion 19 and the outer peripheral surface of the main body shell 4, but the present invention is not limited to this. For example, it can also be configured so that the lower end portion of the outer peripheral side of the outer shell 30 enters the entire area of ​​the gap S1 between the inner end surfaces of the pair of mounting protrusions 24 and the outer peripheral surface of the main body shell 4.

[0086] In addition, in the above-mentioned first and second embodiments, a case is described in which the watch falls from the back side and abuts against a contact surface T such as a floor, but the present invention is not limited to this. For example, when the watch case 1 is arranged on a loading surface such as a table, and the lower parts of the outer ends of a pair of mounting protrusions 24 are in contact with the belt mounting part 19 of the cover part 3 on the loading surface, when the watch case 1 is impacted from above, it also has the same effect as the above-mentioned first and second embodiments.

[0087] In addition, in the above-mentioned first and second embodiments, the case in which the shell component 2 is composed of a hard main body shell 4 and a soft outer shell 5, 30 is described, but the present invention is not limited to this. For example, it can also be composed of a hard main body shell and a hard outer shell, and it can also be formed only by a hard main body shell.

[0088] In addition, in the first and second embodiments described above, the case where the connecting pin 26 is a spring rod is described, but the present invention is not limited to this. For example, it can also be a threaded component with an external threaded portion on one side of the rod-shaped component and an internal threaded portion on the other side of the rod-shaped component. In addition, it can also be a simple rod-shaped component.

[0089] Furthermore, in the first and second embodiments described above, the case where the invention is applied to a wristwatch is described, but the invention need not necessarily be a wristwatch, and can be applied to various clocks such as travel watches, alarm clocks, table clocks, wall clocks, etc. In addition, the invention need not necessarily be a clock, and can also be applied to electronic devices such as mobile communication devices and mobile terminals.

[0090] As mentioned above, although several embodiments of the present invention have been described, the present invention is not limited thereto but includes the invention described in the claims and the equivalent scope.
