BEST MODE FOR CARRYING OUT THE INVENTION A wristwatch band according to an embodiment of the present invention will be described below with reference to FIGS. 1 to 5. [First Embodiment] First, the configuration will be described. 1 is a front view of the wristwatch, FIG. 2A is a rear view of the wristwatch, and FIG. 3 is a right side view of the wristwatch. As shown in these figures, the wristwatch 1 is generally composed of a wristwatch body 2 and a watchband 3 connected to the wristwatch body 2. The wristwatch body 2 is made of resin or metal,
The structure is such that the band mounting recess 2a is integrally formed on the side surface thereof. The watch band 3 includes a metal band main body 31 formed by connecting a plurality of pieces 31a, 31b, 31c ... whose outer surfaces are made of metal, and the band main body 31.
A spring rod 32 as a rod member for attaching the band to the band mounting recess 2a, a synthetic resin mounting member 33 housed in the piece 31a (first piece) of the band body 31 adjacent to the watch body 2, and the like. Has been done. Band body 31
As shown in FIG. 3A, the adjacent pieces of the
It is rotatably pivoted by. Here, for the sake of explanation, the end 31a of the band body 31, that is, the piece 31a closest to the wristwatch body 2 is referred to as a "first piece", and the piece 31b adjacent to the first piece 31a is referred to as a "second piece". Further, as shown in FIG. 2A, a mounting member 33 is mounted between the band body 31 and the wristwatch body 2, and the band body 31 is connected to the wristwatch body 2 via the mounting member 33. There is.

Most of the mounting member 33 is the first piece 31.
It is wrapped by a and the mounting member 33 is hidden when the wristwatch 1 is worn on the wrist.

The mounting member 33 is formed integrally by, for example, pouring a synthetic resin into a mold, and as shown in FIG. 3 (b), on the second piece 31b side, the width direction of the band main body 31 is formed. A first through hole 331 is formed so as to penetrate through. The spring rod 35 is inserted through the first through hole 331. Both ends of the spring rod 35 slightly project from the first through hole 331. On the other hand, the fitting recess 3 is formed in the first piece 31a at a position corresponding to the through hole 331 when the mounting member 33 is mounted.
6 is formed so that the fitting recess 36 and the both ends of the spring rod 35 are fitted to each other. Then, both ends of these spring rods 35 and the fitting recesses 36 of the first piece 31a are fitted together, so that the attachment member 33 and the first piece 31a are joined together. The first piece 31a has a U-shaped end portion in the width direction, and has a shape that encloses the mounting member 33.
That is, both widthwise ends of the mounting member 33 are attached to the mounting member 3
It is bent in a U shape in a sectional view so as to wrap around 3. Therefore, even when the mounting member 33 and the first piece 31a are axially attached by the single spring rod 35,
The mounting member 33 does not rotate with respect to the first piece 31a.

Further, the wristwatch body 2 in the mounting member 33
The side shape is adapted to fit into the band mounting recess 2a of the wristwatch body 2. Specifically, on the wristwatch body 2 side of the mounting member 33, as shown in FIG. 3, an abutment surface 332 that abuts on the wristwatch body 2, a protruding portion 333 that projects toward the wristwatch body 2, and a wristwatch body 2 A buffer portion 334 that wraps around the back surface of the is formed.

As shown in FIGS. 2A and 3, the band body 3 is attached to the wristwatch body 2 side of the mounting member 33.
A second through hole 335 is formed so as to penetrate in the width direction of No. 1, and the spring rod 32 is inserted into the second through hole 335. Both ends of the spring rod 32 slightly project from the second through hole 335. On the other hand, as shown in FIG. 2B, fitting recesses 21 and 22 are formed on the side surface of the band mounting recess 2a of the wristwatch body 2 as holes to be fitted with both ends of the spring rod 32. By fitting the fitting recesses 21 and 22 and both ends of the spring rod 32, the mounting member 33 and the wristwatch body 2 are connected.

Here, as shown in FIG. 2B, the spring rod 32 is a spring rod main body 32 which is inserted into the second through hole 335.
The spring rod main body 32a has protrusions 32b and 32c. Protrusions 32b, 32c
Is urged outward by a spring (not shown) housed in the spring rod body 32a.
Although it protrudes completely from 2a, it is configured to be retractable so as to be housed in the spring rod main body 32a when pushed axially with a force exceeding the biasing force of the spring. In addition, FIG.
As shown in FIG. 5, the protruding portions 32b and 32c can be slightly elastically bent with respect to the spring rod main body 32a in a state of being completely projected from the spring rod main body 32a.

Then, as shown in FIG. 2B, the distance La from the contact surface 332 of the mounting member 33 and the wristwatch body 2 to the axis line connecting the mating recess 21 and the mating recess 22 facing each other is La. The distance Lb from the contact surface 332 to the axis of the spring rod body 32a is slightly larger than the distance Lb. Therefore, when the mounting member 33 and the wristwatch main body 2 are axially attached by the spring rod 32, the spring rod 32 is arranged in a state where the protruding portions 32b and 32c are slightly bent toward the wristwatch main body 2 side. That is, the spring rod 32 as a whole is arranged in a curved state on the side of the second piece 31b. Therefore, the mounting member 33 is biased toward the wristwatch body 2 by the restoring force of the spring rod 32, whereby the wristwatch body 2 and the mounting member 33 are brought into tight contact with each other.

Here, since the mounting member 33 and the wristwatch main body 2 are tightly fitted to each other in the fitted state, the mounting member 33 does not rotate about the spring rod 32.
That is, when the mounting member 33 tries to rotate toward the front surface side of the wristwatch body 2, the rotation is blocked by the protrusion 333, while the mounting member 33 tries to rotate toward the rear surface side of the wristwatch body 2. If so, the buffer 334 prevents the rotation. Further, since the buffer portion 334 wraps around the lower side of the wristwatch body 2, it has a function of buffering the impact on the lower surface of the wristwatch body 2. This allows the wristwatch 1 to have impact resistance from the lower surface.

According to the wristwatch band described above, the following effects can be obtained. (1) The band body 31 can be integrally attached to the wristwatch body 2 with a simple structure. The wristwatch body 2 and the band body 31 are connected to each other via a mounting member 33, but the mounting member 3
Most of 3 is wrapped with the first piece 31a, and since the mounting member 33 is not exposed when the wristwatch 1 is mounted, it looks as if the wristwatch body 2 and the band body 31 are directly connected, and the appearance is It does not hurt.

(2) The mounting member 33 and the wristwatch body 2 are tightly fitted together by the spring rod 32 so as not to rotate with each other, and the mounting member 33 and the first piece 31a are also coupled so as not to rotate. Therefore, the wristwatch body 2 and the band body 31
It is possible to improve the sense of unity with the first piece 3
It is avoided that the mounting member 33 is exposed by opening the la 1a.

[Second Embodiment] Since the structure of the wristwatch band according to the second embodiment is substantially the same as that of the wristwatch band 3 according to the first embodiment, the overlapping structure will not be described. Description will be given using the same reference numerals. The wristwatch 1 according to the second embodiment, as shown in FIG.
It is characterized in that a cutout portion 37 is formed in the lower end portion of a on the second piece 31b side.

In the wristwatch 1 according to the first embodiment,
When the second piece 31b rotates with respect to the first piece 31a,
The lower end of the first piece 31a on the second piece 31b side and the second piece 31
Since the lower end of the first piece 31a on the side of the first piece 31a abuts, a large rotation angle cannot be obtained. However, in the present embodiment, the lower end of the first piece 31a on the side of the second piece 31b is provided. Since the cutout portion 37 is formed, for example, a rotation angle of approximately 90 degrees or more can be secured.

As a result, even when the band body 31 is tightly tightened, the stress applied to the spring rod 32 can be reliably released. Therefore, the opening between the first piece 31a and the wristwatch body 2 is less likely to occur. Therefore, for example, even if a person with a thin wrist wears the wristwatch 1, the sense of unity between the band body 31 and the wristwatch body 2 will not be impaired.

[Third Embodiment] The wristwatch band according to the third embodiment has substantially the same structure as the wristwatch bands according to the first and second embodiments, but It is characterized in that enlarged diameter portions 10 and 11 having an enlarged inner diameter are provided at both ends of the second through hole 335.

Since the degree of freedom at both ends is increased, the workability when fitting the spring rod 32 into the fitting recesses 21, 22 while bending the spring rod 32 can be improved.

In this case, as shown in FIG. 5 (b), in addition to both end portions of the second through hole 335, a stepwise diameter expansion is performed from one end of the second through hole 335 to the other end. Part 1
It is good also as forming 2, 13, 14, 15, 16 intermittently. It is preferable that the expanded diameter portions are formed at equal intervals evenly in order to avoid biased stress on the spring rod 32.

Further, as shown in FIG. 5B, when the expanded diameter portions 11, 12, 13, ... Are intermittently formed in the second through hole 335, the mounting member 33 is made of a soft resin. So
If a large stress is applied to the spring rod 32, the second
The contact portion of the through hole 335 with the spring rod 32 is elastically deformed to buffer the stress. Thereby, the life of the spring rod 32 can be extended.

Further, as shown in FIG. 5 (c), the inner diameter of the second through hole 335 is kept constant over the entire length, and both ends of the spring rod main body 32a are provided outside the spring rod main body 32a. The reduced diameter portions 32d and 32e having an outer diameter smaller than the diameter may be formed. In this case, the inner diameter of the second through hole 335 may be larger than that shown in FIG. As shown in FIG. 5C, even when the both ends of the spring rod main body 32a are reduced in diameter, the second through hole 33 is formed.
When the spring rod main body 32a is inserted into 5, the ring-shaped voids surrounding both end portions of the spring rod main body 32a are secured, so that the flexibility of both ends of the spring rod 32 is increased, and the spring rod 32 is It is possible to improve workability in fitting the fitting recesses 21 and 22 while bending.

The present invention is not limited to the above-described embodiments, but can be appropriately modified without departing from the spirit of the present invention. For example, a pin may be used as the spring rod 32. Moreover, the housing of the wristwatch body 2 may be made of resin or metal. When the case is made of resin, the sense of unity with the metal band 3 can be further improved by coating the case with a metal color.
