[0014] Hereinafter, an embodiment in which the present invention is applied to a watch will be described with reference to Figures 1 to 8

[0015] As shown in Figure 1 and Figure 2 the watch includes a watch case 1 as an object to be connected. Watch band mounting portions 3 for mounting a watch band 2 are provided on the 12 o'clock side and the 6 o'clock side of the watch case 1, respectively. And button switches 4 are provided on the 2 o'clock side, 4 o'clock side, 8 o'clock side, and 10 o'clock side of the watch case 1, respectively.

[0016] In this case, as shown in Figure 3 the watch case 1 includes a lower case 5, an upper case 6, and an outer case 7. The lower case 5 is formed of a metal or a rigid synthetic resin, for example, a rigid synthetic resin having a relatively high rigidity formed by mixing glass fiber or carbon fiber into a polyamide resin. The upper case 6 is formed of a metal such as stainless steel or a titanium alloy.

[0017] As shown in Figure 3 the upper case 6 has a structure that is disposed on the upper portion of the lower case 5 via a waterproof ring 6a. The outer case 7 includes a substantially annular first decorative case 7a mounted on the outer periphery of the upper portion of the upper case 6, and a substantially annular second decorative case 7b mounted on the upper portion of the first decorative case 7a and covering the upper portion of the upper case 6.

[0018] Thus, as shown in Figure 3 the watch case 1 has the following structure: the upper case 6 is disposed on the upper portion of the lower case 5 via the waterproof ring 6a, the first decorative case 7a of the outer case 7 is disposed on the outer periphery of the upper portion of the upper case 6, and the second decorative case 7b of the outer case 7 is disposed on the upper portion of the first decorative case 7a. In this state, the lower case 5, the upper case 6, and the outer case 7 are mutually mounted using a plurality of screws 6b.

[0019] As shown in Figures 1 to 3 ​​As shown, a watch glass 8 is mounted via a gasket 8a at the upper opening of the watch case 1, i.e., the upper opening of the upper case 6. A partition member 9 is provided inside the watch case 1 below the watch glass 8, i.e., inside the upper case 6. Further, a back cover 10 is mounted via a waterproof ring 10a using a plurality of screws 10b at the lower part of the watch case 1, i.e., the lower part of the lower case 5.

[0020] As Figure 3 shown, a watch module 11 is provided inside the watch case 1, i.e., inside the lower case 5. Although not shown, the watch module 11 includes various parts required for watch functions such as a watch movement that causes the hands to move, a display panel that electro-optically displays information such as time, and a circuit section that electrically drives the above components.

[0021] Moreover, as Figures 1 to 3 shown, the watch band 2 is configured such that a watch band main body 12 as an object to be connected is mounted via a connecting body 13 to a watch band mounting portion 3 of the watch case 1 as an object to be connected. In this case, the watch band mounting portion 3 of the watch case 1 includes a pair of mounting protrusion portions 3a provided at the 12 o'clock side and the 6 o'clock side of the outer peripheral portions of the lower case 5 and the upper case 6, respectively. As Figure 4 shown, pin connection holes 3b are respectively provided corresponding to each other on the same axis in the above pair of mounting protrusion portions 3a.

[0022] And, as Figure 1 and Figure 2 shown, the watch band main body 12 is formed by sequentially connecting a plurality of metal watch band blocks 12a, but it may also be formed of synthetic resin. As Figure 3 , Figure 5 and Figure 6 shown, the connecting body 13 includes a mounting member, i.e., a mounting block 15, which is mounted to the end of the watch band main body 12 via a pin member 14, and a connecting member 16 which is mounted to the mounting block 15 and mounts the mounting block 15 to the watch band mounting portion 3 of the watch case 1.

[0023] As Figure 3 , Figures 5 to 7 shown, the mounting block 15 includes one end portion 15a and the other end portion 15b. Among them, the one end portion 15a is disposed between the pair of mounting protrusion portions 3a in the watch band mounting portion 3 of the watch case 1 and faces the outer peripheral surface of the watch case 1, and the other end portion 15b is disposed in a recess 12b of the watch band block 12a provided at the end of the watch band main body 12 and is mounted to the watch band block 12a at the end of the watch band main body 12.

[0024] That is, as Figure 3 , Figures 5 to 7As shown, the mounting block 15 is formed such that the thickness (height) of one end portion 15a is approximately the same as the thickness of the watch case 1, that is, the length (height) in the vertical direction of the outer peripheral surface of the watch case 1, the thickness of the other end portion 15b is approximately the same as the thickness of the strap main body 12, and the other end portion 15b is thinner than the one end portion 15a. Thus, the mounting block 15 is inclined so as to gradually become lower from the upper part of the one end portion 15a toward the upper part of the other end portion 15b, and is integrally formed into a columnar piece having a substantially right-angled triangle shape.

[0025] In this case, as Figure 3 , Figures 5 to 7 shown, in the other end portion 15b of the mounting block 15, a pin mounting hole 17 for inserting the supply member 14 is provided so as to penetrate in the short side direction orthogonal to the long side direction of the strap main body 12. The axial length of the pin member 14 is formed to be the same as the length in the short side direction of the strap block 12a at the end portion of the strap main body 12.

[0026] Thus, as Figure 3 , Figures 5 to 7 shown, the other end portion 15b of the mounting block 15 is configured such that when it is disposed between the concave portions 12b in the strap block 12a at the end portion of the strap main body 12, it corresponds to each pin insertion hole 12c on the same axis, and each of the pin insertion holes 12c is provided on both side portions of the concave portion 12b of the strap block 12a in the short side direction of the strap main body 12.

[0027] And, as Figure 3 , Figures 5 to 7 shown, the other end portion 15b of the mounting block 15 is configured such that in a state where it is disposed in the concave portion 12b of the strap block 12a at the end portion of the strap main body 12, the pin member 14 is inserted from one pin insertion hole 12c on one of the both side portions of the concave portion 12b of the strap block 12a in the short side direction of the strap main body 12 into the pin mounting hole 17 of the other end portion 15b of the mounting block 15 and is inserted into the pin insertion hole 12c on the other of the both side portions of the concave portion 12b of the strap block 12a, and thus is mounted on the strap block 12a at the end portion of the strap main body 12.

[0028] On the other hand, as Figure 3 , Figures 5 to 7 shown, in the one end portion 15a of the mounting block 15, a mounting hole 18 for inserting the tube portion 20 of the connecting member 16 is provided so as to penetrate in the short side direction of the strap main body 12. The mounting hole 18 is formed such that when the one end portion 15a of the mounting block 15 is disposed between a pair of mounting protrusions 3a in the strap mounting portion 3 of the watch case 1, it corresponds to each pin connection hole 3b provided on the pair of mounting protrusions 3a on the same axis.

[0029] As Figure 3 , Figure 6 andFigure 8 As shown, the connecting member 16 is a spring rod for attaching the mounting block 15 to the strap attachment portion 3 of the watch case 1, and includes a tube portion 20 as a cylindrical portion, a spring member 21 disposed within the tube portion 20, a pair of sliding portions 22 slidably disposed on both side portions within the tube portion 20, and a pair of handle portions 23 for sliding the pair of sliding portions 22 along the axial direction of the tube portion 20, respectively.

[0030] Thus, as Figure 3 , Figure 6 and Figure 8 shown, the connecting member 16 is configured such that the pair of sliding portions 22 are pushed outwards from both end portions of the tube portion 20 by the elastic force of the spring member 21. In this case, the outer diameter of the tube portion 20 is formed to be the same size as the inner diameter of the mounting hole 18 of the mounting block 16, and the axial length is formed to be the same as or slightly shorter than the axial length of the mounting hole 18.

[0031] As Figure 8 (b) shown, the spring member 21 is a helical spring, and its outer diameter is formed to be slightly smaller than the inner diameter of the tube portion 20. The axial length of the spring member 21 in the free state, that is, the length in the telescopic direction, is formed to be longer than the length between the pair of sliding portions 22 in the state after moving in the direction of being pushed out from both end portions of the tube portion 20, that is, the length between the inner end portions of the pair of sliding portions 22. Thus, the spring member 21 is configured such that both end portions elastically contact the inner end portions of the pair of sliding portions 22 and apply a force to the pair of sliding portions 22 in the direction of being pushed out from the inside of the tube portion 20 towards the outside.

[0032] As Figure 8 (a) and Figure 8 (b) shown, each of the pair of sliding portions 22 includes a large-diameter sliding body 22a and a small-diameter protruding portion 22b. The sliding body 22a is slidably disposed within the tube portion 20. The outer diameter of the sliding body 22a is formed to be the same as or slightly smaller than the inner diameter of the tube portion 20, and the axial length is formed to be about 1 / 3 of the axial length of the tube portion 20.

[0033] And, as Figure 8 (b) shown, the sliding body 22a is configured such that when disposed on both side portions within the tube portion 20 and being pushed in the direction of being pushed out by the spring member 21, the edge portion of the outer side end portion abuts against the anti-disengagement portion 20a of each edge portion provided at both ends of the tube portion 20 by riveting, so as not to disengage from the outside of the tube portion 20.

[0034] As Figure 8 (a) and Figure 8As shown in FIG. (b), each protruding portion 22b of a pair of sliding portions 22 and the sliding main body 22a are integrally provided on the outer ends of a pair of sliding main bodies 22a on the same axis. The protruding portion 22b does not abut against the anti-disengagement portions 20a at both ends of the pipe portion 20, but is configured to protrude out of the pipe portion 20 from both ends of the pipe portion 20 so as to be able to move in and out.

[0035] That is, as Figure 8 shown in FIG. (a) and Figure 8 FIG. (b), the outer diameter of the protruding portion 22b is formed to be smaller than the outer diameter of the sliding main body 22a and smaller than the inner diameter of the anti-disengagement portions 20a at both ends of the pipe portion 20, and is formed to be substantially the same size as the inner diameter of each pin connection hole 3b of a pair of mounting protrusion portions 3a in the watch case 1 shown in Figure 4 FIG. Also, the axial length of the protruding portion 22b is about 1 / 3 of the length of the sliding main body 22a, and is formed to be substantially the same length as the axial length of the pin connection hole 3b in a pair of mounting protrusion portions 3a.

[0036] Thus, as Figure 8 shown in FIG. (a) and Figure 8 FIG. (b), the protruding portion 22b is configured such that when the sliding main body 22a is pressed toward the outside of the pipe portion 20 by the elastic force of the spring member 21, the protruding portion 22b is pushed out toward the outside of the pipe portion 20 and is respectively inserted into each pin connection hole 3b of a pair of mounting protrusion portions 3a in the watch case 1 shown in Figure 4 FIG. Also, the protruding portion 22b is configured such that when it moves toward the inside of the pipe portion 20 against the elastic force of the spring member 21, it disengages from each pin connection hole 3b of a pair of mounting protrusion portions 3a and is pressed into the inside of the pipe portion 20.

[0037] Moreover, as Figure 8 shown in FIG. (a) and Figure 8 FIG. (b), a handle portion 23 is respectively mounted on each sliding main body 22a of a pair of sliding portions 22. The pair of handle portions 23 are used to slide each sliding main body 22a of a pair of sliding portions 22 axially inside the pipe portion 20.

[0038] That is, as Figure 8 shown in FIG. (a) and Figure 8 FIG. (b), a pair of handle portions 23 respectively include a substantially cylindrical head portion 23a and a rod-shaped shaft portion 23b. The shaft portion 23b passes through each opening portion 24 provided on both side portions of the pipe portion 20 and is mounted on the shaft mounting hole 22c of the sliding main body 22a by welding, screw fixing, etc.

[0039] In this case, as Figure 8 shown in FIG. (a) and Figure 8As shown in FIG. (b), each opening 24 provided on both side portions of the tube portion 20 is formed as a long hole extending along the axial direction of the tube portion 20 from the edge portions at both ends of the tube portion 20. That is, each of the above-mentioned openings 24 is formed to have an axial length in the axial direction of the tube portion 20 slightly shorter than the axial length of the sliding body 22a of the sliding portion 22. And the radial length of each of the above-mentioned openings 24 orthogonal to the axial direction of the tube portion 20 is formed to be the same as or slightly longer than the outer diameter (diameter) of the shaft portion 23b of the handle portion 23.

[0040] And, as Figure 8 shown in FIG. (a) and Figure 8 FIG. (b), each of the above-mentioned openings 24 is formed such that when the protrusions 22b of the pair of sliding portions 22 are respectively pushed out to the outside of the tube portion 20 by the elastic force of the spring member 21 and the edge portions of the outer ends of the pair of sliding bodies 22a abut against the anti-disengagement portions 20a provided at both ends of the tube portion 20, the shaft portions 23b of the pair of handle portions 23 are respectively disposed close to the outer ends located on both ends of the tube portion 20.

[0041] And, each of the above-mentioned openings 24 is formed such that when Figure 8 the protrusions 22b of the pair of sliding portions 22 shown in FIG. (a) and Figure 8 FIG. (b) are respectively pressed into the inside of the tube portion 20 against the elastic force of the spring member 21, the shaft portions 23b of the pair of handle portions 23 are respectively disposed close to or in contact with the inner ends located on the intermediate portion side in the axial direction of the tube portion 20.

[0042] Moreover, as Figure 3 , Figures 5 to 7 shown, at one end portion 15a of the mounting block 15 in the connecting body 13, a slit hole 25 is provided over the entire length of the mounting hole 18, that is, from one end portion to the other end portion of the mounting hole 18. When the tube portion 20 is inserted into the mounting hole 18 of the mounting block 15, the pair of handle portions 23 of the connecting member 16 are inserted into the slit hole 25 in a slidable manner.

[0043] That is, as Figure 3 , Figures 5 to 7 shown, the length of the slit hole 25 in the width direction orthogonal to the axial direction of the mounting hole 18 is formed to be smaller than the inner diameter of the mounting hole 18 and is formed to be substantially the same as or slightly wider than the outer diameter of the shaft portions 23b of the pair of handle portions 23 of the connecting member 16. Thus, the tube portion 20 is configured such that when it is disposed in the mounting hole 18, it will not pass through the slit hole 25 and escape from the mounting hole 18 toward the outer peripheral surface of the watch case 1 in the direction orthogonal to its axial direction.

[0044] And, as Figure 3 , Figures 5 to 7As shown, the slit hole 25 is provided between a pair of mounting protrusions 3a of the strap mounting portion 3 of the watch case 1 and between the opposing surface of one end portion 15a of the mounting block 15 facing the outer peripheral surface of the watch case 1 and the inner peripheral surface of the mounting hole 18, and the opposing surface of one end portion 15a of the mounting block 15 is open. Thus, the slit hole 25 is configured such that when the mounting block 15 is disposed between a pair of mounting protrusions 3a of the strap mounting portion 3 of the watch case 1, the slit hole 25 is blocked by the outer peripheral surface of the watch case 1.

[0045] And, as Figures 5 to 7 shown, a pair of cutout portions 26 are provided at one end portion 15a of the mounting block 15, and the pair of cutout portions 26 are configured to allow a pair of handle portions 23 of the connecting member 16 to rotate and move about the central axis of the mounting hole 18 and to be able to move along the axial direction of the mounting hole 18. That is, the above-mentioned pair of cutout portions 26 include a first cutout portion 26a for allowing a pair of handle portions 23 to rotate and move about the central axis of the mounting hole 18, and a second cutout portion 26b configured to allow the pair of handle portions 23 to move along the axial direction of the mounting hole 18 when rotating and moving.

[0046] In this case, as Figures 5 to 7 shown, the first cutout portion 26a is provided between the opposing surface of one end portion 15a of the mounting block 15 facing the outer peripheral surface of the watch case 1 corresponding to the portion of the slit hole 25 and the inner peripheral surface of the mounting hole 18. The second cutout portion 26b is provided between the lower surface of the mounting block 15 and the inner peripheral surface of the mounting hole 18, and is open to the lower surface side of the mounting block 15, that is, the lower surface side as the back side of the watch case 1. Thus, when the pair of handle portions 23 rotate and move about the central axis of the mounting hole 18 within the pair of first cutout portions 26a and are disposed within the pair of second cutout portions 26b, the pair of handle portions 23 are disposed on the lower surface side of the mounting block 15, that is, the lower surface side of the watch case 1, in an exposed manner.

[0047] And, as Figures 5 to 7 shown, the pair of cutout portions 26 are formed such that the axial length of the mounting hole 18 is longer than the axial length of each protruding portion 22b of the pair of sliding portions 22 and shorter than the axial length of each opening portion 24 provided on both side portions of the tube portion 20. Thus, when the pair of handle portions 23 are disposed within the pair of cutout portions 26, they move only within the region of the pair of cutout portions 26 along the axial direction of the mounting hole 18. Therefore, the tube portion 20 is configured not to come out of the mounting hole 18 of the mounting block 15.

[0048] In this case, as Figures 5 to 7 shown, each second cutout portion 26b of the pair of cutout portions 26 is formed such that when the pair of sliding portions 22 are respectively pushed out to the outside of the tube portion 20 by the elastic force of the spring member 21, the pair of handle portions 23 move toward the pair of mounting protrusions 3a of the strap mounting portion 3 and approach each other as Figure 2 shown.

[0049] And, as Figures 5 to 7 shown, each of the second cut portions 26b of the pair of cut portions 26 is formed such that when the protruding portions 22b of the pair of sliding portions 22 are respectively pressed into the inside of the tube portion 20 against the elastic force of the spring member 21, the pair of handle portions 23 move away from the pair of mounting protrusion portions 3a of the watch band mounting portion 3 and move closer to the inner end portions of the respective second cut portions 26b on the side of the intermediate portion in the axial direction of the tube portion 20.

[0050] On the other hand, as Figures 3 to 7 shown, an engaging portion 28 that engages with the engaging portion 27 provided on the watch case 1 is provided at one end portion 15a of the mounting block 15. The engaging portion 28 includes: a cutout recess 28a that is provided in the upper portion of the opposing surface of the one end portion 15a of the mounting block 15 and is open on the opposing surface and the upper surface of the mounting block 15; and a substantially mountain-shaped engaging convex portion 28b that is provided at the bottom of the cutout recess 28a.

[0051] As Figures 3 to 7 shown, the engaging portion 27 of the watch case 1 includes: an engaging convex portion 27a that is provided on the outer peripheral portion of the watch case 1 between the pair of mounting protrusion portions 3a of the watch band mounting portion 3 and is disposed in the cutout recess 28a of the engaging portion 28 of the mounting block 15; and a substantially valley-shaped engaging recess 27b that is provided on the lower surface of the engaging convex portion 27a and engages with the engaging convex portion 28b of the engaging portion 28 of the mounting block 15.

[0052] Accordingly, as Figure 3 shown, the mounting block 15 is configured such that when it is disposed between the pair of mounting protrusion portions 3a of the watch band mounting portion 3, the engaging convex portion 27a of the engaging portion 27 provided on the watch band mounting portion 3 of the watch case 1 is disposed in the cutout recess 28a of the engaging portion 28 provided on the mounting block 15, and the substantially mountain-shaped engaging convex portion 28b of the engaging portion 28 engages with the substantially valley-shaped engaging recess 27b of the engaging portion 27, so that the mounting block 15 does not shake relative to the watch case 1.

[0053] In addition, the mounting block 15 is formed of sintered metal obtained by sintering metal powders such as stainless steel and titanium alloy. That is, the mounting block 15 is formed by the following method: metal powders such as stainless steel and titanium alloy are mixed into a fluid resin by metal injection molding (MIM) and filled into a molding metal mold, and in this state, the resin is evaporated by sintering treatment to sinter the metal powders. Thus, the mounting block 15 is formed to have high strength.

[0054] Next, a description will be given of the case where the watch band 2 is attached to the watch case 1 of such a watch.

[0055] In this case, the watch case 1 is pre-assembled. At this time, first, after installing the partition member 9 in the upper case 6, the watch glass 8 is installed together with the gasket 8a at the upper opening of the upper case 6. In this state, the upper case 6 together with the waterproof ring 6a is disposed on the upper part of the lower case 5.

[0056] Then, the first decorative case 7a of the outer case 7 is disposed on the upper outer periphery of the upper case 6, and the second decorative case 7b of the outer case 7 is disposed on the upper part of the first decorative case 7a. In this state, the lower case 5, the upper case 6, the first decorative case 7a of the outer case 7, and the second decorative case 7b of the outer case 7 are mutually installed by a plurality of screws 6b. Thus, the watch case 1 is assembled.

[0057] In this state, the watch module 11 is assembled in the watch case 1, and the button switch 4 is installed on the outer periphery of the lower case 5 of the watch case 1. Thereafter, the waterproof ring 10a and the back cover 10 are installed on the lower part of the lower case 5 of the watch case 1. Thus, the watch is assembled. Then, the watch band main body 12 of the watch band 2 is assembled. At this time, the metal watch band blocks 12a are sequentially connected.

[0058] In this state, the watch band 2 is installed on the watch case 1 by the connecting body 13. In this case, first, the connecting member 16 is installed on the mounting block 15 of the connecting body 13. At this time, the mounting block 15 is pre-formed. That is, metal powder such as stainless steel and titanium alloy is mixed into a fluid resin and filled into a forming metal mold, and in this state, the resin is evaporated by sintering treatment to sinter the metal powder. Thus, the mounting block 15 is formed to have high strength.

[0059] The mounting block 15 formed in this way is formed with a mounting hole 18, a slit hole 25, a pair of cut portions 26, and an engaging portion 28 at one end portion 15a, and a pin mounting hole 17 is formed at the other end portion 15b. And, in the case of assembling the connecting member 16, first, the handle portions 23 are respectively installed on the respective sliding main body portions 22a of the pair of sliding portions 22. At this time, the shaft portion 23b of the handle portion 23 is installed in the shaft mounting hole 22c of the sliding main body 22a by welding, screw fixing, or the like.

[0060] Then, the spring member 21 is inserted into the tube portion 20 of the connecting member 16, and the sliding main body 22a of the sliding portion 22 is inserted into the tube portion 20 from both sides of the tube portion 20, respectively. At this time, the handle portion 23 provided on the sliding portion 22 is disposed in the respective opening portions 24 provided at both end portions of the tube portion 20. In this state, both end portions of the tube portion 20 are riveted to form anti-disengagement portions 20a at both end portions of the tube portion 20. Thus, the sliding portion 22 is installed so as not to come out of the tube portion 20, and thus the connecting member 16 is assembled.

[0061] In this state, the connecting member 16 is attached to the mounting block 15. At this time, the tube portion 20 of the connecting member 16 is inserted into the mounting hole 18 of the mounting block 15, and the shaft portions 23b of the pair of handle portions 23 are inserted into the slit holes 25. In this case, the tube portion 20 may be inserted from either one of the end portions of the mounting hole 18.

[0062] That is, if the tube portion 20 is inserted into the mounting hole 18 from one end portion of the mounting hole 18, the shaft portion 23b of the handle portion 23 on the insertion side among the pair of handle portions 23 is inserted into the slit hole 25. Then, if the tube portion 20 approaches the other end portion side of the mounting hole 18, the other handle portion 23 approaches the one end portion of the mounting hole 18. In this state, if the tube portion 20 is further pressed into the mounting hole 18, the shaft portion 23b of the other handle portion 23 is inserted into the slit hole 25 together with the one handle portion 23.

[0063] At this time, the pair of handle portions 23 are arranged corresponding to the pair of cut portions 26 of the mounting block 15. In this state, the pair of handle portions 23 are rotationally moved about the central axis of the mounting hole 18. At this time, within each first cut portion 26a of the pair of cut portions 26, the pair of handle portions 23 are rotationally moved about the central axis of the mounting hole 18 and can be axially moved along the mounting hole 18 and arranged within each second cut portion 26b of the pair of cut portions 26.

[0064] In this state, since the pair of handle portions 23 only axially move within the region of each second cut portion 26b of the pair of cut portions 26, the tube portion 20 does not come out of the mounting hole 18 of the mounting block 15. And, in this state, the pair of handle portions 23 are exposed and arranged on the lower surface side of the mounting block 15, and the tube portion 20 does not pass through the slit hole 25 and come out of the mounting hole 18 in a direction orthogonal to its axial direction. Thus, the connecting member 16 is attached to the mounting block 15.

[0065] Then, the mounting block 15 of this connecting body 13 is attached to the watchband main body 12. At this time, the other end portion 15b of the mounting block 15 is arranged within the concave portion 12b of the watchband block 12a provided at the end portion of the watchband main body 12, and the pin mounting hole 17 of the mounting block 15 is coaxially corresponded to each pin insertion hole 12c provided at both side portions of the concave portion 12b of the watchband block 12a.

[0066] In this state, the pin member 14 is inserted from one pin insertion hole 12c at both side portions of the concave portion 12b of the watchband block 12a into the pin mounting hole 17 of the mounting block 15 and is inserted into the other pin insertion hole 12c at both side portions of the concave portion 12b of the watchband block 12a. Thus, the mounting block 15 is attached to the watchband block 12a at the end portion of the watchband main body 12, thereby assembling the watchband 2.

[0067] When the watch band 2 is installed on the watch band installation portion 3 of the watch case 1, a pair of handle portions 23 of the connecting member 16 installed on the mounting block 15 are moved in a direction approaching each other against the elastic force of the spring member 21, and the protruding portions 22b of the pair of sliding portions 22 are pulled into the tube portion 20.

[0068] In this state, the mounting block 15 is disposed between the pair of mounting protrusions 3a of the watch band installation portion 3, the engaging portion 28 of the mounting block 15 is engaged with the engaging portion 27 provided on the watch band installation portion 3 of the watch case 1, and the protruding portions 22b of the pair of sliding portions 22 are aligned with the pin connection holes 3b provided on the pair of mounting protrusions 3a.

[0069] In this case, when the engaging portion 28 of the mounting block 15 is engaged with the engaging portion 27 provided on the watch band installation portion 3 of the watch case 1, the engaging convex portion 27a of the engaging portion 27 provided on the watch band installation portion 3 of the watch case 1 is disposed in the notch recess 28a of the engaging portion 28 provided on the mounting block 15, and the substantially mountain-shaped engaging convex portion 28b of the engaging portion 28 is engaged with the substantially valley-shaped engaging concave portion 27b of the engaging portion 27. Thereby, the mounting block 15 is prevented from shaking relative to the watch case 1.

[0070] Moreover, when the protruding portions 22b of the pair of sliding portions 22 are aligned with the pin connection holes 3b provided on the pair of mounting protrusions 3a, the pair of sliding portions 22 slide in a direction of being pushed out from the inside of the tube portion 20 due to the elastic force of the spring member 21, and the protruding portions 22b of the pair of sliding portions 22 are inserted into the pin connection holes 3b provided on the pair of mounting protrusions 3a. Thereby, the mounting block 15 is installed on the watch band installation portion 3 by the connecting member 16, and thus the watch band 2 is installed on the watch band installation portion 3 of the watch case 1.

[0071] In this state, the slit hole 25 of the mounting block 15 is blocked by the outer peripheral portion of the watch case 1 located between the pair of mounting protrusions 3a. Therefore, even if the slit hole 25 is provided over the entire length from one end portion to the other end portion of the mounting hole 18 in the mounting block 15, it cannot be seen from the outside of the watch case 1, and thus an improvement in appearance and designability can be achieved.

[0072] Moreover, in this state, the pair of handle portions 23 are disposed in the respective second cut portions 26b of the pair of cut portions 26 of the mounting block 15 so as to be movable in the axial direction of the mounting hole 18, and are disposed so as to be exposed on the lower side of the mounting block 15, that is, on the lower side of the watch case 1. Thereby, in a state where the watch band 2 is installed on the watch band installation portion 3, the pair of handle portions 23 can be moved in the axial direction of the mounting hole 18 within the region of the respective second cut portions 26b of the pair of cut portions 26.

[0073] Next, the case of removing the watch band 2 from the watch band installation portion 3 of the watch case 1 will be described.

[0074] In this case, a pair of handle portions 23 disposed in respective second cutout portions 26b of a pair of cutout portions 26 of the mounting block 15 are moved in a direction approaching each other against the elastic force of the spring member 21.

[0075] Then, respective sliding bodies 22a of the pair of sliding portions 22 slide toward the inner side of the tube portion 20, so that respective protruding portions 22b of the pair of sliding portions 22 are disengaged from respective pin connection holes 3b of the pair of mounting protrusions 3a in the band mounting portion of the watch case 1 and are pulled into the tube portion 20. Thus, the mounting block 15 can be simply detached from between the pair of mounting protrusions 3a of the band mounting portion 3, and thus the band 2 can be easily detached from the band mounting portion 3 of the watch case 1.

[0076] Further, when the connecting member 16 is detached from the mounting block 15, the pair of handle portions 23 disposed in respective second cutout portions 26b of the pair of cutout portions 26 of the mounting block 15 are rotationally moved to the slit hole 25 provided in the tube portion 20. At this time, the pair of handle portions 23 are rotationally moved in respective first cutout portions 26a of the pair of cutout portions 26 about the central axis of the mounting hole 18.

[0077] Thereby, respective shaft portions 23b of the pair of handle portions 23 are disposed in the slit hole 25 of the tube portion 20. In this state, the tube portion 20 is pulled out from the mounting hole 18 of the mounting block 15. At this time, since respective shaft portions 23b of the pair of handle portions 23 move in the slit hole 25 of the mounting block 20, the tube portion 20 is simply disengaged from the mounting hole 18 of the mounting block 15.

[0078] Thus, according to the connecting body 13 of this watch, the mounting block 15 and the connecting member 16 are provided. The mounting block 15 is a mounting member that is mounted on a band main body 12 as an object to be connected and has a mounting hole 18. The connecting member 16 is mounted on the watch case 1 as an object to be connected in such a manner that a sliding portion 22 that slides in a tube portion 20 as a cylindrical portion inserted into the mounting hole 18 has a handle portion 23 and can project in and out from an end portion of the tube portion 20. In the mounting block 15, a slit hole 25 into which the handle portion 23 can be slidably inserted is provided from one end portion to the other end portion of the mounting hole 18, whereby the attachment / detachment operation of the connecting member 16 with respect to the mounting block 15 can be simplified.

[0079] That is, in the connecting body 13 of this watch, a slit hole 25 into which the handle portion 23 can be slidably inserted is provided from one end portion to the other end portion of the mounting hole 18 in the mounting block 15. Thus, when the tube portion 20 of the connecting member 16 is inserted into the mounting hole 18 of the mounting block 15, the handle portion 23 can be inserted into and moved in the slit hole 25 of the mounting block 15. Thereby, the connecting member 16 can be simply mounted on the mounting block 15, and the connecting member 16 can be simply detached from the mounting block 15. Therefore, the band can be easily replaced.

[0080] Further, in the connecting body 13, by providing the slit hole 25 in the mounting block 15 from one end portion to the other end portion of the mounting hole 18, when the tube portion 20 of the connecting member 16 is inserted into the mounting hole 18 of the mounting block 15, the tube portion 20 can be inserted from either one of the two end portions of the mounting hole 18. Thus, the attachment / detachment operation of the connecting member 16 with respect to the mounting block 15 can also be simply performed.

[0081] In this case, in the connecting body 13, the sliding portions 22 are respectively arranged at both end portions inside the tube portion 20, and handle portions 23 are respectively provided on the sliding portions 22. Thereby, the handle portions 23 can be moved along the axial direction of the mounting hole 18, and the sliding portions 22 respectively arranged at both end portions inside the tube portion 20 can slide inside the tube portion 20. Thereby, the sliding operability of the sliding portions 22 can be improved, and thus the watch band replacement can be simply performed.

[0082] In this case, in the connecting body 13, even if the handle portions 23 are respectively provided on the sliding portions 22 arranged at both end portions inside the tube portion 20, since the slit hole 25 is provided in the mounting block 15 from one end portion to the other end portion of the mounting hole 18, when the tube portion 20 of the connecting member 16 is inserted into the mounting hole 18 of the mounting block 15, the tube portion 20 can be inserted from either one of the two end portions of the mounting hole 18, and the handle portions 23 can be inserted from either one of the two end portions of the slit hole 25.

[0083] Further, in the connecting body 13, the slit hole 25 of the mounting block 15 is blocked by the watch case 1. Thus, even if the slit hole 25 is provided in the mounting block 15 from one end portion to the other end portion of the mounting hole 18, when mounted on the watch band mounting portion 3 of the watch case 1, the slit hole 25 can be hidden by the watch case 1 so as not to be seen from the outside. Thereby, the appearance and design can be improved.

[0084] Further, in the connecting body 13, a cutout portion 26 is provided in the mounting block 15. The handle portion 23 of the connecting member 16 is arranged to be able to rotate and move about the central axis of the mounting hole 18 and slide along the axial direction of the mounting hole 18 in the cutout portion 26. Thereby, the handle portion 23 can slide only within the region of the cutout portion 26, and further, the tube portion 20 will not come out of the mounting hole 18 of the mounting block 15.

[0085] That is, the cut portion 26 of the connecting body 13 includes a first cut portion 26a for the handle portion 23 to rotate and move about the central axis of the mounting hole 18, and a second cut portion 26b arranged such that the handle portion 23 can move axially along the mounting hole 18 when rotating. Therefore, the handle portion 23 can rotate and move within the first cut portion 26a about the central axis of the mounting hole 18, and the rotated handle portion 23 can be arranged to be able to move axially along the mounting hole 18 only within the region of the second cut portion 26b. Thus, the tube portion 20 will not come out of the mounting hole 18 of the mounting block 15.

[0086] Moreover, in this connecting body 13, the handle portion 23 is arranged in the cut portion 26 of the mounting block 15 and is exposed on the lower side of the back side of the watch case 1. Thus, even if the slit hole 25 of the mounting block 15 is blocked by the watch case 1, the handle portion 23 can move axially within the cut portion 26 along the mounting hole 18. Therefore, the mounting block 15 can be simply removed from the strap mounting portion 3 of the watch case 1, and thus the strap can be easily replaced.

[0087] Furthermore, in this connecting body 13, the mounting block 15 has an engaging portion 28 that engages with the engaging portion 27 provided on the watch case 1. Thus, when the mounting block 15 is arranged between the pair of mounting protrusions 3a of the strap mounting portion 3, the engaging portion 28 of the mounting block 15 can engage with the engaging portion 27 of the strap mounting portion 3 provided on the watch case 1, thereby reliably preventing the mounting block 15 from shaking relative to the watch case 1.

[0088] That is, in this connecting body 13, when the engaging portion 28 of the mounting block 15 engages with the engaging portion 27 of the strap mounting portion 3 provided on the watch case 1, the engaging convex portion 27a of the engaging portion 27 provided on the strap mounting portion 3 of the watch case 1 is arranged in the cutout recess 28a of the engaging portion 28 provided on the mounting block 15, and the substantially mountain-shaped engaging convex portion 28b of the engaging portion 28 can engage with the substantially valley-shaped engaging concave portion 27b of the engaging portion 27, thereby reliably preventing the mounting block 15 from shaking relative to the watch case 1.

[0089] In addition, in this connecting body 13, the mounting block 15 is formed of sintered metal obtained by sintering metal powders such as stainless steel and titanium alloy. Thus, the mounting block 15 can be formed with high strength. That is, this mounting block 15 is formed by mixing metal powders such as stainless steel and titanium alloy into a fluid resin through metal injection molding (MIM) and filling the mixture into a metal mold for molding. In this state, the resin is evaporated through sintering treatment to sinter the metal powders, so that even if the shape of the mounting block 15 is complex, it can be simply manufactured.

[0090] In addition, in the above-described embodiment, the case where the handle portions 23 of the connecting member 16 are respectively provided on a pair of sliding portions 22 at both ends provided inside the tube portion 20 has been described. However, the present invention is not limited thereto. For example, the handle portion 23 may be provided only on one of the pair of sliding portions 22.

[0091] Moreover, in the above-described embodiment, the case where the mounting block 15 is provided with the slit hole 25 and the cutout portion 26 has been described. However, the present invention does not necessarily require the cutout portion 26, and it may be a configuration in which only the slit hole 25 is provided. In this case, it is not necessary to hide the slit hole 25 with the outer peripheral surface of the watch case 1, and it is sufficient to expose the slit hole 25 by opening it on the lower side of the mounting block 15 corresponding to the back side of the watch case 1.

[0092] Furthermore, in the above-described embodiment, the case where the engaging portion 28 is provided on the mounting block 15 and the engaging portion 27 is provided on the strap mounting portion 3 of the watch case 1 has been described. However, the present invention is not limited thereto. For example, it may be a configuration in which the engaging portion 27 is provided on the mounting block 15 and the engaging portion 28 is provided on the strap mounting portion 3 of the watch case 1.

[0093] In addition, in the above-described embodiment, the case where the mounting block 15 is formed of sintered metal obtained by sintering metal powder has been described. However, the present invention is not limited thereto. For example, the mounting block 15 may also be formed of synthetic resin.

[0094] Moreover, in the above-described embodiment, the case where the mounting block 15 is mounted on the strap block 12a at the end of the strap body 12 and is mounted on the strap mounting portion 3 of the watch case 1 through the connecting member 16 has been described. However, the present invention is not limited thereto. For example, the mounting block 15 may also be provided on the strap mounting portion 3 of the watch case 1, and the mounting block 15 may be mounted on the strap block 12a at the end of the strap body 12 by using the connecting member 16.

[0095] Figure 9 is a view showing another embodiment in this case, and is a view corresponding to Figure 3 In this case, the mounting block 15 constituting the connecting body 13 is provided on the strap mounting portion 3 of the watch case 1 as the object to be connected, and the above-described connecting member 16 is mounted on the mounting block 15. Moreover, a concave portion 31 for accommodating the mounting block 15 and a pair of arm portions 32 forming both side portions of the concave portion 31 are provided on the strap block 12c at the outermost end of the strap body 12, and pin connecting holes (not shown) for inserting the protruding portions 22b of the pair of sliding portions 22 of the above-described connecting member 16 are provided on the opposing inner surfaces of the respective arm portions 32. Furthermore, an engaging portion 28 that engages with the engaging portion 27 provided on the strap block 12c at the outermost end of the strap body 12 is provided on the mounting block 15. Regarding the other structures, for Figure 3The same parts as shown are marked with the same reference numerals and their description is omitted.

[0096] Similarly, in such an embodiment, when the watchband 2 is attached to the watchband attachment portion 3 of the watch case 1, first, the connecting member 16 is attached to the mounting block 15 so that a pair of handle portions 23 are exposed on the lower surface side of the mounting block 15. Then, the pair of handle portions 23 are moved in a direction approaching each other, and the protruding portions 22b of the pair of sliding portions 22 are pulled into the tube portion 20. In this state, after the engaging portion 27 provided at the endmost portion of the watchband main body 12 is engaged with the engaging portion 28 provided at the mounting block 15, the protruding portions 22b of the pair of sliding portions 22 are inserted into the pin connection holes of the pair of arm portions 32 provided at the endmost watchband block 12a. Thus, the mounting block 15 is attached to the endmost watchband block 12a through the connecting member 16, and thus the watchband 2 is attached to the watchband attachment portion 3 of the watch case 1. And, by the reverse steps, the watchband 2 can be detached from the watchband attachment portion 3 of the watch case 1.

[0097] That is, in Figure 9 the shown connecting body 13, the attachment and detachment operation of the connecting member 16 with respect to the mounting block 15 can also be simply performed, and by using such a connecting body 13, the watchband replacement can be easily performed. And, by providing the engaging portion 28 at the mounting block 15 that engages with the engaging portion 27 provided at the endmost watchband block 12c of the watchband main body 12, the endmost watchband block 12c of the watchband main body 12 can be reliably prevented from shaking with respect to the mounting block 15.

[0098] In addition, in the above embodiment, the case of being applied to a watch is described, but the present invention is not necessarily limited to a watch. For example, it can also be applied to belt-like members used in clothing, bags, and the like.

[0099] The above describes one embodiment of the present invention, but the present invention is not limited thereto, including the invention described in the claims and its equivalent scope.
