Further, since the timepiece band 8 is attached to the band attaching portion 10 by the fastening member 16, even if the timepiece band 8 is made of a soft synthetic resin such as urethane resin, the timepiece band 8 is fastened by the fastening member 16. The one end 8a is reliably and satisfactorily attached to the band attaching portion 10. Therefore, even if the watch band 8 is pulled with respect to the wrist watch case 1, the one end portion 8a of the watch band 8 does not come off from the band attaching portion 10, and the watch case 1 is favorably attached to the wrist by the watch band 8. be able to.

That is, in the fastening member 16, the first screw member 17 is attached to the female screw portion 18 b of the second screw member 18 in a state where the first screw member 17 and the second screw member 18 are inserted into the tubular member 19. The male screw portion 17a is screwed and tightened. As a result, the pair of reinforcing members 12 are pressed against both end portions of the tubular member 19, so that the one end portion 8a of the timepiece band 8 is securely and firmly attached to the band attaching portion 10.

On the other hand, when the timepiece band 8 thus attached to the band attaching portion 10 is attached to the arm, the one end portion 8a of the timepiece band 8 rotates around the tubular member 19 of the fastening member 16, and the timepiece band 8 is rotated. Fits on your arm and wears it. At this time, the one end portion 8a of the watch band 8 rotates around the fastening member 16, but the rotation restricting member 20 has its rotation suppressed and blocked by the rotation stopping member 22. The rotation range of the one end 8a of the watch band 8 is regulated by the rotation regulation member 20.

That is, when the one end portion 8 a of the watch band 8 rotates around the fastening member 16 toward the upper side of the band mounting portion 10, the upper surface of the one end portion 8 a of the watch band 8 is attached to the connecting side portion 20 b of the rotation restricting member 20. Since the sides are in contact with each other, the rotation of the one end portion 8a of the watch band 8 is restricted. Further, when the one end 8 a of the watch band 8 rotates around the fastening member 16 toward the lower side of the band attaching part 10, the lower surface of the one end 8 a of the watch band 8 is the thick portion 11 of the band attaching part 10. Since it abuts against, the rotation of the one end portion 8a of the watch band 8 is restricted.

As a result, the one end portion 8a of the timepiece band 8 has a position where the lower surface of the one end portion 8a of the timepiece band 8 abuts on the thick portion 11 of the band mounting portion 10 and the upper surface of the one end portion 8a of the timepiece band 8 that is the rotation restricting member. The rotation range of the one end portion 8a of the timepiece band 8 is regulated by rotating between the position of the timepiece 20 and the position of contacting the connection side portion 20b. As a result, the watch band 8 can be attached to the wrist in a state in which it is well fitted.

Further, when removing the wristwatch case 1 from the wrist, one end portion 8a of the watchband 8 rotates around the fastening member 16 and the watchband 8 can be removed from the wrist. Also at this time, when the one end 8a of the timepiece band 8 is rotated around the fastening member 16 toward the upper side of the band attaching portion 10, the one end 8a of the timepiece band 8 is attached to the connecting side portion 20b of the rotation restricting member 20. Since the upper surface of the watch band abuts, rotation of the one end portion 8a of the watch band 8 is restricted. As a result, the one end portion 8a of the watch band 8 does not rotate more than necessary, so that the wristwatch case 1 can be properly removed from the wrist.

In this state, when the wristwatch case 1 is placed face up on the table, the rotation of the one end portion 8a of the timepiece band 8 around the fastening member 16 is restricted by the connecting side portion 20b of the rotation restricting member 20. As a result, the wristwatch case 1 is elastically arranged by the one end portion 8a of the watch band 8 in a state of floating on the desk.

As described above, according to the wristband mounting structure of the wristwatch, the wristwatch case 1 provided with the band mounting portion 10, the watch band 8 having the one end 8a disposed between the band mounting portions 10, and the watch band 8 A rotation restricting member 20 arranged on both sides of the one end portion 8a so as to straddle the one end portion 8a and suppressing rotation of the watch band 8 with respect to the wristwatch case 1, and one end portion 8a of the watch band 8 is rotated together with the rotation restricting member 20 to the band attaching portion 10. Since the fastening member 16 that can be attached is provided and the rotation stopper member 22 that regulates the rotation of the timepiece band 8 and the rotation regulating member 20 around the fastening member 16 as a center, the rotation of the timepiece band 8 is ensured. And can be regulated well.

That is, in this band mounting structure for a wristwatch, when the timepiece band 8 rotates about the fastening member 16, the rotation restricting member 20 suppresses the rotation of the timepiece band 8 with respect to the band mounting portion 10 of the wristwatch case 1 and also rotates the band. The rotation range of the watch band 8 can be reliably regulated by the stopper member 22. Therefore, even if the timepiece band 8 is formed of a soft synthetic resin, the rotation of the timepiece band 8 can be reliably and satisfactorily regulated.

In this case, since the rotation stopping member 22 is configured to suppress the rotation of the rotation restricting member 20 around the fastening member 16 and restrict the rotation of the watch band 8, the rotation stopping member 22 restricts the rotation of the watch case 1 with respect to the band mounting portion 10. The rotation of the member 20 can be suppressed and prevented by the rotation stopping member 22, and accordingly, when the timepiece band 8 rotates around the fastening member 16, the rotation restricting member 20 is prevented from rotating. Thus, even if the watch band 8 is made of a soft synthetic resin, the rotation range of the watch band 8 can be reliably regulated.

That is, the rotation restricting member 20 connects the pair of side edge portions 20a arranged on both sides of the one end portion 8a of the watch band 8 and the pair of side edge portions 20a across the upper surface side of the one end portion 8a of the watch band 8. And a connecting side portion 20b for connecting the side portions 20a, and the thin mounting portions 21 of the pair of side portions 20a are arranged between the one end portion 8a of the watch band 8 and the band mounting portion 10 by the fastening member 16. By being rotatably attached to the band attachment portion 10, when the one end portion 8a of the timepiece band 8 rotates around the fastening member 16, the rotation restricting member 20 controls the rotation range of the one end portion 8a of the timepiece band 8. It can be regulated reliably and satisfactorily.

That is, when the timepiece band 8 rotates around the fastening member 16, the rotation restricting member 20 has a position where the lower surface of the one end portion 8 a of the timepiece band 8 abuts on the thick portion 11 of the band attaching portion 10, and the timepiece. By rotating the one end portion 8a of the timepiece band 8 between the position where the upper surface of the one end portion 8a of the band 8 contacts the connecting side portion 20b of the rotation restricting member 20, the rotation range of the one end portion 8a of the timepiece band 8 is increased. Can be regulated reliably and satisfactorily.

Further, in this band mounting structure, the rotation stopping member 22 has the pin mounting hole 23 provided in the band mounting portion 10 and the pin restriction hole provided in the rotation restricting member 20 and corresponding to the pin mounting hole 23 on the same axis. 24 and the pin member 25 inserted into the pin attachment hole 23 and the pin regulation hole 24, the pin member 25 is changed from the pin attachment hole 23 of the band attachment portion 10 to the pin regulation hole 24 of the rotation regulation member 20. The position of the rotation restricting member 20 can be reliably regulated with respect to the band mounting portion 10 with a simple structure of only inserting, and thus the rotation of the rotation regulating member 20 with respect to the band mounting portion 10 can be reliably prevented. it can.

In this case, even if the mounting cover portion 13 of the band mounting portion 10 is formed of a soft synthetic resin such as urethane resin, the reinforcing member 12 of the band mounting portion 10 is formed of a metal such as stainless steel and the rotation restricting member 20. Is made of a highly rigid synthetic resin such as a polyamide resin, the position of the rotation restricting member 20 can be reliably regulated with respect to the band attaching portion 10 by the pin member 25. It is possible to reliably prevent the rotation of the rotation restricting member 20 with respect to.

Further, in this band mounting structure, the fastening member 16 includes the first screw member 17 having the male screw portion 17a, the neck portion 17b, and the head portion 17c, and the female screw with which the male screw portion 17a of the first screw member 17 is screwed. By having the shaft portion 18a provided with the portion 18b, the neck portion 18c, and the second screw member 18 having the head portion 18d, the one end portion 8a of the watch band 8 is attached to the band by the fastening member 16. It can be securely attached to the portion 10.

In this case, the fastening member 16 is inserted into the through hole 8b provided in the one end portion 8a of the timepiece band 8, is arranged between the pair of reinforcing members 12, and has the first screw member 17 and the second screw member. By further including the tubular member 19 into which 18 is inserted, the first screw member 17 and the second screw member 18 are inserted into the tubular member 19, and the male screw portion of the first screw member 17 is inserted. By screwing 17a into the female screw portion 18b of the second screw member 18 and tightening it, the one end portion 8a of the watch band 8 can be firmly attached to the band attaching portion 10.

That is, when the male screw portion 17a of the first screw member 17 is screwed into the female screw portion 18b of the second screw member 18 and the fastening member 16 is tightened, the head portion 17c of the first screw member 17 is attached to one side. Since the cover portion 13 is pressed against the one reinforcing member 12 and the head portion 18d of the second screw member 18 presses the other mounting cover portion 13 against the other reinforcing member 12, the pair of reinforcing members 12 are connected to each other. Can be pressed against both ends of the band mounting portion 10, whereby the one end portion 8a of the watch band 8 can be firmly mounted between the pair of reinforcing members 12 of the band mounting portion 10, and the rotation restricting member 20 can be attached to the tubular member 19. Can be securely attached.

Further, in this band mounting structure, each pin mounting hole 23 of the rotation stopping member 22 of the band mounting portion 10 has the head portion 17c of the first screw member 17 and the head portion 18d of the second screw member 18 of the fastening member 16. Are provided in corresponding areas E, that is, in the counterbore portions 13b of the respective mounting cover portions 13 of the band mounting portion 10, so that the respective pin members 25 are connected to the head portion 17c of the first screw member 17 and the first screw member 17. It can be respectively covered by the head part 18d of the two screw members 18.

That is, the pin members 25 of the rotation stopping member 22 are inserted into the pin mounting holes 23 of the band mounting portion 10 and the pin restricting holes 24 of the rotation regulating member 20, so that the rotation regulating member 20 with respect to the band mounting portion 10 is inserted. Since the pin members 25 can be covered with the head portion 17c of the first screw member 17 and the head portion 18d of the second screw member 18 in a state in which the rotation of the pin members 25 is prevented, In addition, each pin member 25 can be hidden so as not to be seen from the outside, and thus it is possible to provide a preferable one in terms of appearance and design.

(Second embodiment)
Next, a second embodiment in which the present invention is applied to a wristwatch will be described with reference to FIG. The same parts as those of the first embodiment shown in FIGS. 1 to 6 will be described with the same reference numerals.
As shown in FIG. 7, this wristwatch has a configuration in which the pin restricting hole 30 of the rotation stopping member 22 provided in the mounting portion 21 of the rotation restricting member 20 is different from that of the first embodiment, and other than that, the first embodiment. It has the same configuration as.

That is, as shown in FIG. 7, the pin restricting hole 30 of the rotation stopping member 22 is larger than the outer diameter of the pin member 25 along an arc centered on the insertion hole 21a into which the tubular member 19 of the fastening member 16 is inserted. Is also formed long. In this case, the length of the pin regulation hole 30 in the arc direction centered on the insertion hole 21a may be formed within about twice the diameter of the pin member 25, and preferably 1 of the diameter of the pin member 25. It is formed to have a length of about 5 times. As a result, the pin restriction hole 30 is configured such that the pin member 25 inserted therein moves within a predetermined angle range along an arc centered on the insertion hole 21a.

In such a wristwatch band mounting structure, in addition to the same effects as the first embodiment, the pin restriction hole 30 of the rotation stopping member 22 is located outside the pin member 25 along an arc centered on the insertion hole 21a. By being formed longer than the diameter, when the one end portion 8a of the watch band 8 rotates around the fastening member 16, the pin member 25 of the rotation stopping member 22 is predetermined along the pin restriction hole 30. It can be moved within the angular range.

Therefore, the rotation restricting member 20 can be rotated about the fastening member 16 only within the range in which the pin member 25 relatively moves within the pin restricting hole 30 of the rotation stopping member 22, so that the fastening member 16 is centered. It is possible to widen the rotation range of the one end 8a of the timepiece band 8 which allows the wearability of the timepiece band 8 to the arm to be improved, and to further improve the timepiece band 8 to the wrist as compared with the first embodiment. Can be fitted well.

(Third Embodiment)
Next, a third embodiment in which the present invention is applied to a wristwatch will be described with reference to FIG. In this case, the same parts as those of the second embodiment shown in FIG.

That is, as in the second embodiment, the pin restriction hole 30 of the rotation stopping member 22 is larger than the outer diameter of the pin member 25 along an arc centered on the insertion hole 21a into which the tubular member 19 of the fastening member 16 is inserted. Is also formed long. Thereby, the pin restriction hole 30 is configured so that the pin member 25 inserted therein moves within a predetermined angular range along an arc centered on the insertion hole 21a.

As shown in FIG. 8, a first elastically deforming portion 31 and a second elastically deforming portion 32 are provided at both ends of the pin restriction hole 30 in the longitudinal direction. The first elastically deformable portion 31 approaches the end portion 30a of the pin regulation hole 30 that is located in the clockwise direction in FIG. 8 centered on the insertion hole 21a provided in the attachment portion 21 of the rotation regulation member 20. By providing the hole portion 31a, it is formed as a thin portion between the first hole portion 31a and the end portion 30a of the pin regulation hole 30 which approaches the first hole portion 31a.

In this case, as shown in FIG. 8, in the first hole portion 31a of the first elastic deformation portion 31, the inner peripheral surface of the portion approaching the end portion 30a of the pin restriction hole 30 has an end portion 30a of the pin restriction hole 30.

As a result, as shown in FIG. 8, the first elastic deformation portion 31 pushes the pin member 25 inserted into the pin restriction hole 30 in the clockwise direction in FIG. The thin-walled portion located between the end portion 30a of the pin restriction hole 30 and the first hole portion 31a is configured to elastically deform toward the first hole portion 31a when applied.

On the other hand, the second elastic deformation portion 32, as shown in FIG. 8, is a pin regulation hole 30 located in the counterclockwise direction in FIG. 8 centered on the insertion hole 21 a provided in the attachment portion 21 of the rotation regulation member 20. By providing the second hole portion 32a close to the end portion 30b of the pin, similar to the first elastically deforming portion 31, a thin wall is provided between the second hole portion 32a and the end portion 30b of the pin restriction hole 30 approaching the second hole portion 32a. Is formed as a part.

Also in this case, in the second hole portion 32a of the second elastic deformation portion 32, as shown in FIG. 8, the inner peripheral surface of the portion approaching the end portion 30b of the pin restriction hole 30 has the end of the pin restriction hole 30. It is formed in the same arc as the arc of the portion 30b so as to project substantially in parallel toward the inside of the second hole 32a, and the inner peripheral surface of the portion facing this is the same arc as the arc of the end 30b of the pin restriction hole 30. It is formed almost parallel.

As a result, in the second elastically deformable portion 32, as shown in FIG. 8, the pin member 25 inserted into the pin regulation hole 30 moves counterclockwise in FIG. 8 to move to the end portion 30b of the pin regulation hole 30. When pressed, the thin portion located between the end portion 30b of the pin restriction hole 30 and the second hole portion 32a is configured to elastically deform toward the second hole portion 32a.

In such a wrist watch band mounting structure, in addition to the same operational effects as those of the first and second embodiments, the pin restricting hole 30 located in the rotation direction of the rotation restricting member 20 around the fastening member 16 is provided. Since the first elastic deformation portion 31 and the second elastic deformation portion 32 are provided on both sides, the one end portion 8a of the timepiece band 8 rotates around the fastening member 16 and the pin member 25 of the rotation stopping member 22 moves. When moving along the pin restriction hole 30 by a predetermined angle range, either one of the first elastically deformable portion 31 and the second elastically deformable portion 32 can be elastically deformed to absorb the shock. ..

Then, the pin member 25, which relatively moves within a predetermined angle range and relatively moves in the pin restriction hole 30, is pressed against the end portion 30a of the pin restriction hole 30. Since the first elastic deformation portion 31 located in the portion 30a elastically deforms toward the first hole portion 31a side, the impact can be buffered by the elastic deformation of the first elastic deformation portion 31.

Similarly, in this band mounting structure, when the one end portion 8a of the timepiece band 8 is rotated downwardly of the wristwatch case 1 around the fastening member 16, the pin member 25 of the rotation stopping member 22 is inserted into the pin restriction hole 30. The pin member 25, which relatively moves along the predetermined angle range along the pin restricting hole 30, is pressed against the end 30b of the pin restricting hole 30. Since the second elastically deforming portion 32 located at the end portion 30b elastically deforms toward the second hole 32a side, the elastic deformation of the second elastically deforming portion 32 can buffer the shock.

In the third embodiment described above, the case where the pin restriction hole 30 of the rotation stopping member 22 is formed longer than the outer diameter of the pin member 25 has been described. However, the pin restriction hole is not limited to this, and Similar to the first embodiment, the inner diameter may be formed to be the same as the outer diameter of the pin member 25. Also in this case, if the first elastically deforming portion 31 and the second elastically deforming portion 32 are provided at both ends of the pin regulation hole located in a direction along an arc centered on the insertion hole 21a into which the fastening member 16 is inserted. good.
