Japanese Patent Laid-Open No. 10-28605

However, Nakadome like Patent Document 1 has the following problems.
(1) The rod attached to the hole of the band must be removed and inserted every time it is attached to or detached from the arm. When removing the stick attached to the hole of the band, the large diameter part of the attached rod is the band hole on the back side of the band. Since it is caught on the periphery of the band, the vicinity of the band hole is easily damaged. Specifically, when carrying a watch equipped with a band, a tensile force acts on the band due to the rigidity of the band, so that the small diameter part of the rod that sticks out of the center of the band rod and the center of the band hole is located on the inner peripheral surface of the band hole. Since the stick sticking out from the state in which the large diameter portion is caught on the periphery of the band hole is pulled out, the vicinity of the band hole is easily damaged.
In this way, in the configuration in which the stick attached at the position of the band hole and the push pinning member are engaged, a load is applied only to a part of the band at the time of attachment / detachment, and the durability of the band is low.

(2) When the stick is inserted into the band hole, it is difficult to register the position of the stick and the band hole, so that the mounting operation is difficult. That is, when the open ends of the band are fastened, positioning of the band and the band is necessary, and the position of the stick provided on one band and the hole of the other band must be aligned. The stick is hidden behind the frame and difficult to see.
In addition, the structure provided with the stick | rod attached to the position on the opposite side to patent document 1, for example, the stick | stick sticking to the plate member etc. which contact | abut an arm is protrudingly provided, and the stick | rod which sticks to a band hole so that this plate may be covered with a band Also in the case of a configuration in which the stick is inserted, the stick attached to the back side of the band is hidden, so the situation that it is difficult to align the stick and the band hole is not changed, and the mounting operation is difficult.
Also, the band has a plurality of holes, and it is not always possible to insert a rod attached to a predetermined hole every time it is attached to or detached from the arm, so the band length at the time of fastening is not the desired length There is.

  Accordingly, an object of the present invention is to provide a fastener that is easy to perform a fastening operation and a fastening release operation and that is excellent in durability quality of a member to be fastened such as a band, a long body including the fastener, and the long body.

Next, with reference to FIGS. 14 to 17, an operation of fastening the bands 11 and 12 with the middle ring 3 and attaching the timepiece 1 to the arm (attachment target) will be described.
As shown in FIG. 14, the 12 o'clock side band 12 is arranged on the arm side of the 6 o'clock side band 11, and the 6 o'clock side band 11 is covered on the 12 o'clock side band 12, The second member 3B is engaged.
Here, by overlapping the overlapping portion 312 of the button unit 30 disposed on the back side of the 6 o'clock side band 11 with the lower surface of the first bar 41 of the second member 3B, the overlapping portion 312 and the rising portion 313 are the first. It will be in the state supported by the crosspiece 41 so that rotation was possible.
FIG. 15 shows a side surface of the timepiece 1 in this state. Since the tensile force acting between the bands 11 and 12 acts in the direction of pressing the overlapping portion 312 and the rising portion 313 (FIG. 14) as the rotation shaft portion toward the first crosspiece 41 side, the overlapping portion 312 and the rising portion The part 313 is stably supported by the first crosspiece 41.

Next, the first member 3A is rotated toward the second member 3B (in the direction of the arc of the arrow in FIG. 14) with the overlapping portion 312 and the rising portion 313 (FIG. 14) as the rotation center. FIG. 14 shows the rotation axis A at this time. In this way, when the first member 3A and the second member 3B are relatively rotated, the engaging convex portion 322 protrudes on the front side in the rotation direction of the first member 3A.
FIG. 16 is a partial cross-sectional side view of the first mounting member 20, the button unit 30, and the second mounting member 40. The first member 3A is the second mounting member around the rotation axis A (FIG. 14). When rotated to the 40 side, the engaging convex portion 322 abuts against the tapered surfaces 433 and 433 of the second mounting member 40.
At the time of this contact, as shown in FIG. 16, the engagement convex portion 322 is pushed inward in the width direction of the band 11 by the force component acting in the direction substantially along the rising direction of the side wall 43, so Since it is guided inward, the engaging convex part 322 is inserted into the engaging concave part 432 from the inside of the side wall 43 as shown in FIG. Thus, the bands 11 and 12 are fastened by engaging the engaging convex part 322 with the engaging concave part 432 from the inner side to the outer side of the side wall 43. In other words, the engagement convex portion 322 is engaged with the engagement concave portion 432 from the biasing direction proximal end side of the coil spring 34 (FIG. 8) toward the biasing direction distal end side.
In addition, when the engaging convex part 322 is engaged with the engaging concave part 432, a part of the button unit frame 31 is connected to the side walls 43, 43 of the second mounting member 40, the first crosspiece 41, and the second crosspiece 42 (see FIG. 14) and accommodated inside.

When releasing the fastening of the bands 11 and 12, both push buttons 321 and 321 are pushed toward the inner side in the width direction of the band 11. The engaging protrusions 322 and 322 are retracted inward in the width direction of the band 11 in conjunction with the pressing operation of the push buttons 321 and 321, and are disengaged from the engaging recess 432. Therefore, the push buttons 321 and 321 are pressed and held. As the first member 3A is lifted, the first member 3A and the second member 3B are relatively rotated in the direction opposite to that at the time of fastening. Thereby, the overlapping portion 312 and the rising portion 313 are detached from the first bar 41, and the fastening of the bands 11 and 12 is released.
