Embodiments for Carrying out the Invention

[0009] With reference to FIGS. 1 to 15, an embodiment of an equipment case according to the present invention and a watch including the same will be described. In this embodiment, a case where the equipment case is a case of a watch (wristwatch) is exemplified. Note that, although various technically preferable limitations are imposed on the embodiments described below for carrying out the present invention, the scope of the present invention is not limited to the following embodiments and illustrated examples.

[0010] [Configuration] In the following embodiments, "circumferential direction Cd" means the direction Cd shown in FIGS. 1 and 2, and "radial direction Rd" means the direction Rd shown in FIG. 2. As shown in FIGS. 1 to 3, a watch 100 according to this embodiment includes an equipment case 10. The equipment case 10 includes a case body 1 (see FIG. 3), a plurality of first exterior members 5, a plurality of second exterior members, and an upper surface member 8. In the embodiment, the second exterior member includes a first side surface member 6 and a second side surface member 7 as will be described later.

[0011] In an embodiment, the case body 1, the first exterior member 5, the second exterior member (the first side member 6 and the second side member 7), and the upper surface member 8 are all formed of a metal material such as titanium, stainless steel (SUS), or aluminum. Note that the materials constituting the case body 1 and the like are not limited to those exemplified here. The case body 1, the first exterior member 5, the second exterior member (the first side member 6 and the second side member 7), and the upper surface member 8 may all be formed of the same material, or may be formed of different materials.

[0012] As shown in FIG. 4, the case body 1 is formed in a substantially short column shape. The case body 1 of the present embodiment has a hollow cylindrical portion 11 that is open at the top and bottom in the thickness direction H (see FIG. 2) of the timepiece 100, and a band attachment portion 12 to which a timepiece band (not shown) is attached.

[0013] Various components such as a module (not shown) are accommodated in the hollow portion inside the cylindrical portion 11. Although the specific configuration of the module will not be described in detail, when the timepiece 100 is an electronic timepiece, various operating parts of the timepiece 100, a control part for controlling these, a battery, etc. are included in the module.

[0014] The timepiece 100 may include an analog display unit provided with hands (not shown) or the like, or may include a digital display unit provided with, for example, a liquid crystal display unit or the like. For example, when the timepiece 100 has an analog display method, as an operating part, it has hands, a gear train (wheel train mechanism) for rotating the hands, a drive part (motor, etc.), and the like. When the timepiece 100 has a digital display method, as an operating part, instead of the above configurations, it includes a display unit including a liquid crystal (Liquid Crystal) display panel or the like, and this display unit is disposed on the front surface side (viewing side) of the timepiece. Note that the timepiece 100 may be a hybrid type having both a digital method and an analog method, and in this case, it has both sets of components as operating parts. The control part is mounted on a circuit board (not shown) or the like and controls display operations and the like by the operating part.

[0015] The cylindrical portion 11 has a large-diameter portion 11a with a larger outer diameter and a small-diameter portion 11b with a smaller outer diameter than the large-diameter portion 11a, and a stepped portion 11c is formed at the boundary between the large-diameter portion 11a and the small-diameter portion 11b. On the outer portion of the equipment case 1 (in the embodiment, the side portion on the 3 o'clock side of the watch), various operation parts 3 (such as push buttons and crowns) for the user to perform various input operations are provided. In the illustrated example, a through hole 13 for inserting a shaft portion (not shown) of the operation part 3 into the equipment case 1 is formed at the side portion of the large-diameter portion 11a at the position of the operation part 3. Note that the arrangement, number, shape, etc. of the operation parts 3 are not limited to the illustrated example.

[0016] Also, at the side portion of the large-diameter portion 11a at the attachment position of the second exterior member (the second side face member 7 described later), a recessed portion 14 to which a buffer member 16 (see "buffer member 16a" shown in FIGS. 3, 5, etc.) described later is adhered is formed. At the stepped portion 11c, pin fixing holes 15 are formed corresponding to the attachment positions of the second exterior members (the first side face member 6 and the second side face member 7). One end side of a member locking pin 17 is press-fitted into the pin fixing holes 15. The member locking pin 17 is formed of a metal such as stainless steel (SUS), for example. Also, a buffer member 16 (see "buffer member 16b" shown in FIGS. 3, 5, etc.) is adhered in the vicinity of the position on the stepped portion 11c where the member locking pin 17 is arranged.

[0017] FIG. 5 shows an arrangement example of the buffer members 16 attached to the case body 1. Also, in FIG. 5, a state is shown in which one end side of a member locking pin 17 is press-fitted into each pin fixing hole 15 of the case body 1. As shown in FIG. 5, buffer members 16 (buffer members 16a, 16b) are arranged in the recessed portion 14 formed in the large-diameter portion 11a, the vicinity of the member locking pin 17, etc., respectively. The buffer members 16 (buffer members 16a, 16b) are formed of, for example, rubber (cushioning rubber having cushioning properties), etc. Note that the material forming the buffer members 16 (buffer members 16a, 16b) is not limited to this. The material, thickness, etc. may be appropriately changed according to the installation position.

[0018] The buffer members 16 (buffer members 16a and 16b) have an adhesive surface at least on the mounting side to the case body 1 and are adhered to the case body 1. As will be described later, a plurality of second exterior members (the first side face member 6 and the second side face member 7) are attached to the side portion of the cylindrical portion 11 of the case body 1. Since the buffer member 16 is disposed on the outer side of the case body 1 (the cylindrical portion 11 of the case body 1), when each second exterior member (the first side face member 6 and the second side face member 7) is attached, the buffer member 16 is provided between the case body 1 and each second exterior member (the first side face member 6 and the second side face member 7).

[0019] The band attachment portions 12 are provided on the outer sides of the cylindrical portion 11 (the large-diameter portion 11a in the embodiment) of the case body 1 at the 12 o'clock side and the 6 o'clock side of the watch (i.e., the upper and lower end portions in FIG. 1). Through holes 121 through which a spring bar or the like is inserted when attaching a band are provided in the band attachment portions 12 across the width direction W (see FIG. 2) of the device case 10. Further, the first exterior member 5 described later is screwed to the band attachment portions 12, and screw holes 122 are formed corresponding to the fixing positions by screws 9 (see FIGS. 3 and the like) (see FIGS. 4 and the like). Note that the first exterior member 5 may be screwed to anywhere on the case body 1 and is not limited to the band attachment portions 12. Even when the first exterior member 5 is screwed to a position other than the band attachment portions 12, screw holes are formed in the case body 1 corresponding to the fixing positions by the screws 9.

[0020] A back cover member (not shown) for closing the opening portion on the back side is provided on the lower side of the case body 1 (the back side of the watch 100). Note that the case body 1 and the back cover member may be integrally formed and the opening portion may not be provided on the lower side of the case body 1. Further, a windproof member 4 is attached to the end portion on the opening side of the upper side of the case body 1 (the visible side, the front side of the watch) via a waterproof ring 41 (see FIGS. 8 to 10 and the like). By interposing the waterproof ring 41 or the like between the opening portion of the case body 1 and the windproof member 4, the opening on the upper side of the case body 1 is closed in a state where airtightness is ensured. The windproof member 4 is a transparent member (cover member) formed of, for example, a glass material, a transparent resin material, or the like.

[0021] As shown in FIGS. 1 to 3, the first exterior member 5 is disposed at positions facing each other with the case body 1 (the cylindrical portion 11 of the case body 1) interposed therebetween. In the embodiment, the first exterior member 5 is attached laterally to the band attachment portions 12 protruding from the 12 o'clock side and the 6 o'clock side of the case body 1 (see FIG. 11), and is fastened to the band attachment portions 12 by screws 9.

[0022] The portion of the first exterior member 5 that rides on the upper surface of the band attachment portion 12 is the eaves portion 51. Inside the eaves portion 51, screw receiving holes 512 are provided at positions corresponding to the screw holes 122 formed in the band attachment portions 12. The screw receiving holes 512 are preferably provided from the back side of the eaves portion 51 and do not penetrate to the front side for aesthetic design reasons. In FIGS. 1 to 3, the positions of the screw receiving holes 512 are indicated by broken lines. Also, the side of the eaves portion 51 on the case body 1 side has an arc shape along the cylindrical shape of the cylindrical portion 11 of the case body 1. A fitting groove portion 513 (see FIG. 3 etc.) into which a hook portion 81 (see FIG. 12 etc.) provided on the back side of the upper surface member 8 described later is fitted is formed along the arc-shaped edge of this arc-shaped portion.

[0023] The second exterior member is a member that is disposed on the side portion of the case body 1 and is fitted to the case body 1 from above. It includes a first side surface member 6 disposed on the 2 o'clock side, 4 o'clock side, 8 o'clock side, and 10 o'clock side of the clock, and a second side surface member 7 disposed on the 3 o'clock side and 9 o'clock side of the clock. FIG. 6 is a perspective view schematically showing a state where the first side surface member is assembled and attached to the case body, and FIG. 7 is a perspective view schematically showing a state where the second side surface member is attached to the case body. FIG. 6 shows a state where the buffer member 16 and the member locking pin 17 are attached to the case body 1, and FIG. 7 shows a state where the second side surface member 7 is further attached to the case body 1 in the state where the first side surface member 6 is attached in FIG. 6.

[0024] In the embodiment, the first side member 6 is formed by combining a first component 61 formed in a frame shape and a second component 62 formed in a substantially T shape. Through holes 611 and 621 that penetrate in the width direction w1 of the first side member 6 (see FIG. 2) in the combined state are formed at corresponding positions of the first component 61 and the second component 62, respectively.

[0025] After combining the first component 61 and the second component 62 so that the through holes 611 and 621 are in a penetrating state, the first component 61 and the second component 62 are integrated into the first side member 6 by inserting a shaft member 63 through the through holes 611 and 621. Note that the shapes of the first component 61 and the second component 62 constituting the first side member 6 are not limited to the illustrated examples. The first side member 6 can realize a rich variety of appearance designs by combining, as the first component 61 and the second component 62, for example, those with different colors, surface textures, etc.

[0026] As shown in FIG. 8, at least a part of the first side member 6 is installed on the stepped portion 11c of the case body 1. A pin insertion hole 64 is formed on the side of the first side member 6, which is the second exterior member, that is disposed on the stepped portion 11c. The pin insertion hole 64 may be provided so as to penetrate both the first component 61 and the second component 62, or may be formed in either one of them. FIG. 8 shows an example in which the pin insertion hole 64 is formed in the first component 61. Also, the pin insertion hole 64 may or may not penetrate the first side member 6. The other end side of a member locking pin 17 whose one end side is press-fitted into the pin fixing hole 15 is inserted into the pin insertion hole 64. Thereby, the first side member 6 is positioned on the case body 1 and locked so as not to move in the circumferential direction Cd.

[0027] In this embodiment, in the assembled state of the first side member 6, the first component 61 is longer than the second component 62 in the radial direction Rd, and the second component 62 is longer than the first component 61 in the thickness direction H. As a result, when the first side member 6 is locked to the case body 1 such that the first component 61 contacts the outer surface of the cylindrical portion 11, a gap 622 is formed between the second component 62 and the outer surface of the cylindrical portion 11. As will be described later, at the time of assembly, the engaging portion 81 provided on the upper surface member 8 is accommodated in this gap 622 portion.

[0028] The second side member 7 has a side portion 71 disposed on the side of the large-diameter portion 11a of the cylindrical portion 11 of the case body 1, and a protruding portion 72 that protrudes from this side portion 71 toward the cylindrical center C (FIGS. 1 and 2) of the cylindrical portion 11. The side of the case body 1 in the side portion 71 and the protruding portion 72 has an arc shape along the cylindrical shape of the cylindrical portion 11 of the case body 1. In this embodiment, as described above, the operation portion 3 (such as a push button or a crown) is provided on the side portion at the 3 o'clock side of the clock, and a through hole 13 is provided at a position corresponding to the operation portion 3 in the large-diameter portion 11a. Correspondingly, a notch portion 73 is formed at a position corresponding to the operation portion 3 and the through hole 13 on the side portion 71 of the second side member 7 disposed on the 3 o'clock side of the clock.

[0029] An accommodation groove portion 74 is formed along the arc-shaped end portion on the upper surface of the protruding portion 72. The protruding portion 72 in which the accommodation groove portion 74 is formed is disposed on the step portion 11c in the assembled state to the case body 1. As shown in FIG. 9, the engaging portion 81 of the upper surface member 8 described later is accommodated in the accommodation groove portion 74 at the time of assembly.

[0030] In a portion of the second side member 7, which is the second exterior member, disposed at the stepped portion 11c, a pin insertion hole 75 is formed corresponding to the position of the member locking pin 17. As shown in FIG. 7 and the like, the pin insertion hole 75 of the present embodiment is provided in the housing groove portion 74. The other end side of the member locking pin 17, one end side of which is press-fitted into the pin fixing hole 15, is inserted into the pin insertion hole 75. Thereby, the second side member 7 is positioned on the case body 1 and locked so as not to move in the circumferential direction. Note that the second side member 7 may be formed such that both end portions in the circumferential direction Cd are formed obliquely so as to somewhat cover the adjacent first side member 6. In this case, it is difficult to form a gap between the second exterior members, and the appearance is excellent, which is preferable.

[0031] As shown in FIG. 10, the pin insertion hole 75 is a through hole, and the other end side of the member locking pin 17 penetrates the second side member 7, which is the second exterior member, and protrudes upward from the pin insertion hole 75. On the lower surface side of the upper surface member 8, a notch portion for receiving the protruding portion of the member locking pin 17 is provided at the position where the member locking pin 17 protrudes. In the present embodiment, as will be described later, a notch portion 82 (see FIG. 12) is formed in the engaging portion 81 formed on the lower surface side of the upper surface member 8 corresponding to the position where the member locking pin 17 protrudes. Thereby, the engaging portion 81 is received in the housing groove portion 74 without hitting the protruding member locking pin 17. Further, since the protruding portion of the member locking pin 17 fits into the notch portion 82, the upper surface member 8 is positioned and free rotation in the circumferential direction Cd is restricted.

[0032] Also, as shown in FIG. 10, the pin insertion hole 75 formed in the protruding portion 72 is a long hole that is longer in the radial direction Rd of the case main body 1 (the cylindrical portion 11 of the case main body 1) than the diameter of the member locking pin 17. That is, the member locking pin 17 inserted into the pin insertion hole 75 abuts against the wall on the case main body 1 side of the pin insertion hole 75, but does not abut against the outer wall, and a certain amount of play is provided. How long the pin insertion hole 75 should be and how much play should be provided are matters that can be set as appropriate. For example, when a strong impact is received from the 3 o'clock side or 9 o'clock side of the clock due to dropping or the like, this play allows the second side member 7 to move toward the case main body 1 side, and while crushing the buffer member 16 (buffer member 16a) provided between the large-diameter portion 11a of the case main body 1 and the second side member 7 which is the second exterior member, the second side member 7 is displaced toward the case main body 1 side.

[0033] As shown in FIG. 11 and the like, the upper surface member 8 is formed in a substantially annular shape and is arranged so as to press the first exterior member 5 and the first side member 6 and the second side member 7 which are the second exterior members from above. As shown in FIG. 12, the upper surface member 8 has a hook portion 81 (see FIG. 9 and the like) that is substantially L-shaped in a cross-sectional view on the lower surface side. The hook portion 81 is preferably provided over the entire circumference along the circumferential direction Cd of the upper surface member 8.

[0034] When the upper surface member 8 is arranged above the case main body 1 from above the first side member 6 and the second side member 7 and the like, the hook portion 81 is adapted to fit into the gap 622 of the first side member 6 and the accommodation groove portion 74 of the second side member 7. Thereby, even if the hook portion 81 is provided over the entire circumference of the upper surface member 8, it does not get in the way and can be arranged above the first exterior member 5, the first side member 6, and the second side member 7. Note that the gap 622 of the first side member 6 and the accommodation groove portion 74 of the second side member 7 are provided with almost no gap, and by accommodating the hook portion 81 therein, displacement of the first side member 6 and the second side member 7 is prevented, and the first side member 6 and the second side member 7 can be pressed almost uniformly from above over the entire circumference.

[0035] As shown in FIG. 13, in this embodiment, after attaching the first exterior member 5, the second exterior member (the first side member 6 and the second side member 7), and the upper surface member 8 to the case body 1, the first exterior member 5 is attached from the side of the case body 1.

[0036] At this time, the L-shaped hook portion 81 of the upper surface member 8 is hooked on the fitting groove portion 513 formed in the first exterior member 5, and the upper surface member 8 is fitted to the first exterior member 5. In this state, as shown in FIGS. 14 and 15, the case body 1 and the first exterior member 5 are screwed and fixed with screws 9 from the back side of the equipment case 10.

[0037] [Operation] Next, the operation of the equipment case 10 according to this embodiment and the clock 100 including the same will be described.

[0038] When assembling the equipment case 10 of this embodiment and the clock 100 including the same, a module is accommodated in the case body 1, the opening portion on the visible side is closed with the windproof member 4, and the opening portion on the non-visible side is closed with the back cover member.

[0039] Then, as shown in FIG. 5 for example, a buffer member 16 (buffer member 16a) is adhered to the recessed portion 14 provided in the large-diameter portion 11a of the cylindrical portion 11 of the case body 1. Further, one end side of each member locking pin 17 is press-fitted into each pin fixing hole 15 formed in the stepped portion 11c. Furthermore, buffer members 16 (buffer members 16b) are adhered to both sides of the member locking pins 17 attached to the 2 o'clock side, 4 o'clock side, 8 o'clock side, and 10 o'clock side of the clock and in the vicinity of the member locking pins 17 attached to the 3 o'clock side and 9 o'clock side of the clock above the stepped portion 11c.

[0040] Next, as shown in FIG. 6, the first component 61 and the second component 62 are fitted together, and the shaft member 63 is inserted into the through holes 611 and 621 in the through state and integrated to form the first side member 6. Then, the first side member 6 is attached to the case body 1 from above so that the other end sides of the member locking pins 17 provided on the 2 o'clock side, 4 o'clock side, 8 o'clock side, and 10 o'clock side of the clock are inserted into the pin insertion holes 64 of the first side member 6.

[0041] Also, as shown in FIG. 7, the second side member 7 is attached to the case body 1 from above so that the other end sides of the member locking pins 17 provided on the 3 o'clock side and 9 o'clock side of the clock are inserted into the pin insertion holes 75 of the second side member 7. Further, as shown in FIG. 11, the upper surface member 8 is arranged from above so as to press the first side member 6 and the second side member 7 which are the second exterior members. At this time, the engaging portion 81 provided on the lower surface side of the upper surface member 8 is made to fit into the gap 622 (see FIG. 8) between the first side member 6 and the case body 1 and the accommodation groove portion 74 (see FIG. 9) of the second side member 7. Also, the position of the upper surface member 8 in the circumferential direction Cd is adjusted so that the notch portions 82 (see FIG. 12) provided at two locations on the engaging portion 81 correspond to the positions of the member locking pins 17 protruding from the pin insertion holes 75 (see FIG. 9).

[0042] Thereby, the first side member 6 and the second side member 7 which are the second exterior members are locked by the member locking pins 17, and it is prevented that they come off on the outer peripheral side of the case body 1 or the position in the circumferential direction Cd is shifted. At the same time, they are pressed from above by the upper surface member 8, and it is also prevented that they come off upward.

[0043] Also, by fitting the tip of the member locking pin 17 that locks the second side member 7 into the notch portion 82 of the engaging portion 81, the positioning of the upper surface member 8 can be accurately performed, and the rotation of the upper surface member 8 in the circumferential direction Cd is also restricted. Therefore, for example, even when various logos or the like are provided on the upper surface member 8, it is possible to prevent the orientation from changing.

[0044] And finally, as shown in FIG. 13, the first exterior member 5 is attached to cover the 6 o'clock side band attachment portions 12 and the 12 o'clock side band attachment portions 12 on the side portion of the case body 1, respectively. At this time, by allowing the hook portion 81 of the upper surface member 8 to be hooked on the fitting groove portion 513 of the first exterior member 5, the first exterior member 5 and the upper surface member 8 are fitted together, and the upper surface member 8 is in a state where it cannot come off upward. In this state, as shown in FIG. 14, a screw 9 is inserted through the screw hole 122 from the back side of the device case 1, and the case body 1 and the first exterior member 5 are fixed by screwing.

[0045] As shown in FIG. 15, the first exterior member 5 is in a state of being pulled toward the case body 1 side (i.e., the lower side in the thickness direction H) by the screw 9 inserted from the back side of the case body 1. The upper surface member 8 with the hook portion 81 hooked on the fitting groove portion 513 of the first exterior member 5 is also pulled downward, making it even more difficult to come off upward. Thus, by using the screw 9 only at the fixing portion between the case body 1 and the first exterior member 5, the exterior members divided into a plurality (i.e., the first exterior member, the second exterior members (the first side surface members 6 and the second side surface members 7), and the upper surface member) can be securely fixed to the case body 1.

[0046] [Effect] As described above, the device case 10 in this embodiment includes the case body 1, a plurality of first exterior members 5, a plurality of second exterior members (the first side surface members 6 and the second side surface members 7), and the upper surface member 8. The plurality of second exterior members (the first side surface members 6 and the second side surface members 7) are fitted into the case body 1 from above, and by pressing this from above with the upper surface member 8, the second exterior members (the first side surface members 6 and the second side surface members 7) cannot come off upward. Also, the first exterior member 5 fitted with the upper surface member 8 is fastened to the case body 1 with the screw 9.

[0047] Thus, with only the screw 9 that fastens the first exterior member 5 to the case body 1, all of the plurality of exterior members (the first exterior member 5 and the second exterior members (the first side face member 6 and the second side face member 7)) and the upper face member 8 arranged on the side portion of the case body 1 are fixed to the case body 1. For this reason, the number of screw components can be reduced, and the number of locations where screw holes are provided is also reduced, so that the screwing space can be minimized, and miniaturization of the equipment case 10 can be achieved.

[0048] Also, the plurality of first exterior members 5 of the present embodiment are arranged at positions facing each other with the case body 1 interposed therebetween. Specifically, the first exterior member 5 is provided corresponding to the band attachment portions 12 on the 6 o'clock side and the 12 o'clock side in the clock. Although the first exterior member 5 is a member fixed by the screw 9 in the embodiment, by arranging it at a position facing each other with the case body 1 interposed therebetween, each exterior member (the first exterior member 5 and the second exterior members (the first side face member 6 and the second side face member 7)) and the upper face member 8 can be reliably fixed to the case body 1 in a well-balanced manner using a small number of screws 9.

[0049] Also, the case body 1 of the present embodiment is provided with pins (member locking pins 17) whose one ends are press-fitted corresponding to the second exterior members (the first side face member 6 and the second side face member 7). The second exterior members (the first side face member 6 and the second side face member 7) have pin insertion holes 64 and 75, and the other ends of the member locking pins 17 are inserted into the pin insertion holes 64 and 75. Thereby, the second exterior members (the first side face member 6 and the second side face member 7) can be temporarily fixed even before being finally fastened by the screw 9, and displacement during assembly and the like can be prevented, so that it is easy to assemble.

[0050] Also, the upper face member 8 of the present embodiment has an L-shaped hook portion 81 on the lower face side, and the upper face member 8 can be fitted to the first exterior member 5 by the hook portion 81 being hooked on a groove portion (fitting groove portion 513) formed in the first exterior member 5. Thereby, simply by hooking the hook portion 81 on the fitting groove portion 513, the upper face member 8 can be easily temporarily fixed so as not to come off upward.

[0051] Also, a buffer member 16 (16a, 16b) is provided between the case body 1 of the present embodiment and the second exterior member (the first side member 6 and the second side member 7). Thereby, even when the case body 1 and the second exterior member (the first side member 6 and the second side member 7) are formed of a metal material, the metals do not directly collide with each other, and it is possible to prevent damage or breakage. Also, the impact resistance of the entire equipment case 10 can be enhanced.

[0052] Among the pins (member locking pins 17) of the present embodiment, those provided corresponding to the second side member 7 which is the second exterior member penetrate the second side member 7 and project upward. On the lower surface side of the upper surface member 8, a notch 82 for receiving the protruding portion of the member locking pin 17 is provided at the position where the member locking pin 17 projects. Therefore, when the upper surface member 8 is attached from above the second exterior member (the second side member 7), by aligning the protruding portion of the member locking pin 17 with the notch 82, it is possible to easily position the upper surface member 8 in the circumferential direction Cd. Also, rotation of the upper surface member 8 in the circumferential direction Cd can be restricted.

[0053] Also, the pin insertion hole 75 of the present embodiment is a long hole that is long in the radial direction Rd of the case body 1. A buffer member 16a is provided between the second exterior member (the second side member 7) and the case body 1. By providing a play in the radial direction Rd in the pin insertion hole 75, when an impact is applied in the radial direction Rd, the second exterior member (the second side member 7) can be displaced while crushing the buffer member 16a by this play amount. Thereby, the impact can be effectively absorbed, and damage to the equipment case 10 and modules or the like housed therein can be prevented. Thereby,

[0054] Moreover, the clock of the present embodiment includes the device case according to any one of claims 1 to 7. As a result, even when attaching the plurality of divided exterior members (a plurality of first exterior members 5, a plurality of second exterior members (the first side member 6 and the second side member 7), and the upper surface member 8) to the case body 1, the number of screwing points can be reduced, and each exterior member can be configured to be difficult to come off from the case body 1. For this reason, a clock 100 with excellent design can be realized with a small number of screw component parts. In addition, since there are fewer locations where space for screw holes needs to be secured, miniaturization of the device case 10 and the clock 100 including the same can be realized.

[0055] [Modification Example] In addition, although the embodiments of the present invention have been described above, it goes without saying that the present invention is not limited to such embodiments, and various modifications are possible without departing from the gist thereof.

[0056] For example, in the above embodiment, the members externally attached to the case body 1 are exemplified as the first exterior members 5 provided on the 6 o'clock side and the 12 o'clock side of the clock, the first side members 6 attached to the 2 o'clock side, 4 o'clock side, 8 o'clock side, and 10 o'clock side of the clock, and the second side members 7 (a plurality of second exterior members) provided on the 3 o'clock side and the 9 o'clock side of the clock, and the upper surface member 8. However, the members externally attached to the case body 1 are not limited thereto. For example, instead of the second side members 7 provided on the 3 o'clock side and the 9 o'clock side, a plurality of small members equivalent to the first side members 6 may be provided. That is, the second exterior members may be further divided into a plurality of parts.

[0057] Also, for example, in the embodiment, only the member locking pin 17 for locking the second side member 7 protrudes, and two notches 82 for receiving this are provided on the upper surface member 8 side. However, the member locking pin 17 protruding on the upper surface member 8 side is not limited to this. The member locking pin 17 protruding on the upper surface member 8 side may be, for example, the member locking pin 17 for locking the first side member 6, or all of the member locking pin 17 for locking the first side member 6 and the member locking pin 17 for locking the second side member 7 may protrude on the upper surface member 8 side. In this case, notches 82 corresponding to all the protruding member locking pins 17 are provided on the upper surface member 8 side.

[0058] Also, for example, in the embodiment, an example in which the first side member 6 is composed of the first component 61 and the second component 62 is shown. However, the first side member 6 may be composed of one component. In this case, the number of components can be reduced, and the operation of assembling and integrating the first component 61 and the second component 62 can be eliminated. Conversely, the second side member 7 may be a member formed by assembling a plurality of components and integrating them. In this case, a more complex appearance can be achieved.

[0059] Also, for example, the first exterior member and the second exterior member may be formed of a metal material other than titanium, stainless steel (SUS), aluminum, etc., or may be formed of a material other than metal, such as glass or ceramic. Also, the first exterior member and the second exterior member may all be formed of the same material, or those formed of different materials may be provided in combination.

[0060] For example, in the embodiment, the first exterior member 5 that has a fitting groove portion 513 for hooking the hooking portion 81 of the upper surface member 8 and is fastened by the screw 9 is provided on the 6 o'clock side and the 12 o'clock side of the case body 1. However, the first exterior member 5 is not limited to this. The first exterior member 5 only needs to fit with the upper surface member 8 to prevent the upper surface member 8 from coming off upward, and it may be a member provided other than the 6 o'clock side and the 12 o'clock side. If the member that fits with the upper surface member 8 is fastened to the case body 1 by the screw 9, the upper surface member 8 and each member pressed from above by the upper surface member 8 can be fixed to the case body 1.

[0061] Also, in the present embodiment, the case where each first exterior member 5 is fastened by two screws 9 and fixed by a total of four screws 9 on the 6 o'clock side and the 12 o'clock side is illustrated. However, the number of screws used for fixing is not limited to four. For example, the first exterior members 5 on the 6 o'clock side and the 12 o'clock side may each be fixed by one screw 9. In this case, it can be fixed by a total of two screws 9 on the 6 o'clock side and the 12 o'clock side, and the number of screw parts and the screwing positions can be further reduced.

[0062] Also, the upper surface member 8 only needs to fit with the first exterior member 5 and is not limited to having a hooking portion 81 as shown in the embodiment. Also, the hooking portion 81 is not limited to being provided over the entire circumference of the upper surface member 8, and it only needs to be provided at least at the fitting portion with the first exterior member 5 to be screwed. In this case, the second exterior member (the first side surface member 6 and the second side surface member 7) may not be provided with the gap 622 or the accommodation groove portion 74.

[0063] Also, in the present embodiment, the case where only the pin insertion hole 75 provided in the second side surface member 7 is a long hole that is long in the radial direction of the case body 1 is shown. However, at least a part of the pin insertion holes only needs to be a long hole that is long in the radial direction of the case body 1, and it is not limited to only the pin insertion hole 75.

[0064] For example, the pin insertion hole 64 provided in the first side member 6 may be a long hole that is long in the radial direction of the case body 1. Also, both the pin insertion hole 75 and the pin insertion hole 64 may be long holes that are long in the radial direction of the case body 1. When both the pin insertion hole 75 and the pin insertion hole 64 are long holes, the second exterior member (the first side member 6 and the second side member 7) can be displaced with respect to impacts from various directions, and it can be expected that the impact resistance will be further improved. When the pin insertion hole 64 is a long hole, it is preferable to provide a buffer member 16 also between the first side member 6 and the small diameter portion 11b.

[0065] Also, in the present embodiment, the second exterior member (the first side member 6 and the second side member 7) is fixed to the case body 1 with the member locking pin 17, but it is not limited to this configuration. A double-sided tape may be arranged instead of the buffer member 16, and the second exterior member (the first side member 6 and the second side member 7) may be fixed to the case body 1 with a double-sided tape.

[0066] Also, for example, in the above embodiment, the case where the equipment case 10 is applied to the clock 100 is illustrated, but the equipment case 10 is not limited to the case of a clock. The equipment case 10 of the present embodiment may be widely applied to cases of equipment that houses components that are concerned about being damaged by impacts, etc. inside the case body 1. For example, it can also be widely applied to various smartwatches, sports watches and other electronic devices, and wearable devices that acquire biological information such as heart rate and blood flow information in addition to time.

[0067] Although some embodiments of the present invention have been described above, the scope of the present invention is not limited to the above-described embodiments, and includes the scope of the invention described in the claims and the equivalent scope thereof.
