[Problems to be solved by the invention]
However, in the wristwatch band of Patent Document 1, when both the piece and the connecting piece are formed of metal, not only the touch is bad, but the adjacent pieces are sufficiently bent in order to sufficiently bend each other. There is a problem that it is difficult to fit to the arm because the interval between the bodies and the interval in the connecting direction between the frame and the connecting piece must be widened. In such a wristwatch band, if the connecting piece is made of metal and the piece is made of a soft synthetic resin such as urethane resin, the above-mentioned problems can be solved, but the entire band is twisted. When an external force is applied more than necessary, there is a problem in that the frame body is elastically deformed and the pin member is detached from the frame body.

And as shown in FIG. 4, it is formed in the substantially circular arc shape. Furthermore, insertion holes 14 into which the spring pins 7 at both ends of the pin member 3 are inserted are provided on the opposing surfaces of the recess 4 of the exterior member 11 corresponding to the locking holes 8 of the pair of side wall portions 12. Yes. The insertion hole 14 is provided only on the inner surface side of the concave portion 4 of the exterior member 11 so as not to be exposed to the outside from both end surfaces in the bandwidth direction.
[0015]
When assembling such a wristwatch band, first, the pin members 3 are respectively inserted into the respective insertion holes 5 provided on both sides of the connecting piece 2 in the connecting direction, and both end portions of each pin member 3 are connected to the connecting piece 2 respectively. Protrude from. That is, the metal cylinder portion 6 of the pin member 3 is inserted into the insertion hole 5 of the connecting piece 2 and penetrated, and the spring pins 7 provided at both end portions of the metal cylinder 6 so as to protrude and protrude are protruded from the connecting piece 2. In this state, the two connecting pieces 2 are respectively disposed in the recesses 4 provided on both sides in the connecting direction of the piece 1. At this time, the spring pin 7 of the pin member 3 protruding from the connecting piece 2 is pushed into the metal cylinder 6 against the spring force, and the connecting piece 2 is arranged in the recess 4 of the piece 1 in this state.
[0016]
When each spring pin 7 of the connecting piece 2 corresponds to each insertion hole 14 and each locking hole 8 provided in the piece 1, each spring pin 7 passes through the insertion hole 14 of the piece 1 to the locking hole 8. Locked. That is, the spring pin 7 is pushed out by the spring force, passes through the insertion hole 14 of the exterior member 11 that is the locking portion 8 of the frame body 1, and is inserted into the locking hole 8 of the side wall portion 12 of the reinforcing member 10. Locked. As a result, the two connecting pieces 2 are pivotally mounted in the recess 4 of the piece 1 in a state where each of the connecting pieces 2 protrudes from the piece 1, and the connecting piece 2 protruding from this recess 4 is connected to another adjacent piece. It inserts in the recessed part 4 of the body 1, and it connects with the pin member 3 similarly to the above. Thereby, the two piece bodies 1 are connected by the connecting piece 2, and a wristwatch band is formed by sequentially repeating this operation.

In this case, since the piece 1 includes the reinforcing member 10, even if an external force in the twisting direction is applied to the entire band, the reinforcing member 10 can reliably prevent deformation of the entire piece 1, and the reinforcing member 10. Since both end portions of the pin member 3 are locked in the locking holes 8 provided in the side wall portion 12, the side wall portion 12 is not deformed even when an external force in the twisting direction is applied to the entire band. The pin member 3 can be firmly held without being detached from the frame body 1, thereby sufficiently securing the strength against twisting of the entire band. Further, since the lower surface of the frame body 1 is located below the lower surface of the connection piece 2, even when the connection piece 2 is formed of a metal material, the connection piece 2 is not attached to the arm when attached to the arm. Since the lower surface of the exterior member 11 of the frame body 1 is always in contact with the arm, the touch when worn on the arm is good and the arm can be further fitted.
[0019]
In addition, although the said embodiment described the case where the connection part 13 of the reinforcement member 10 of the frame 1 was formed in the simple strip | plate shape, it is not restricted to this, For example, the 1st modification shown in FIG. As described above, the connecting portion 15 of the reinforcing member 10 may have a structure in which side plates are integrally formed on both sides of a flat plate. In this case, the width between the concave portions 4 and 4 on both sides of the frame body 1, that is, the length in the connecting direction between the concave portions 4 and 4 may be made sufficiently wider than that of the above embodiment. With such a structure, since the connecting portion 15 including the flat plate and the side plates on both sides is bridged between the pair of side wall portions 12, the reinforcing member 10 becomes more rigid and the strength of the entire band against twisting is increased. Can be further increased.
[0020]
In the above-described embodiment, the case where the pin member 3 is configured by a spring bar in which the spring pin 7 is removably attached to both ends of the metal tube 6 is described. As in the second modification shown in FIG. 8, a simple round bar-shaped pin member 16 may be used. In this case, an insertion hole 17 into which the pin member 16 is inserted into the exterior member 11 of the piece 1 may be provided so as to penetrate from the inner surface of the recess 4 to the outer surface. In such a structure, the pin member 16 is inserted into the insertion hole 17 from the outside of the piece body 1 and is inserted into the locking hole 8 provided in the side wall portion 12 of the reinforcing member 10, and the insertion hole of the connecting piece 2 is inserted. 5 so that the connecting work between the piece 1 and the connecting piece 2 can be facilitated, and the structure of the pin member 16 is simple, so that the pin member 16 can be manufactured at low cost, and the entire band can be manufactured. Cost reduction can also be achieved.
