Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a structure of a watch band used for a wristwatch.

[0002]

[Prior art]

 Conventionally, a watch band using a telescopic body piece has been developed to make it easy to attach the watch to the wrist. As shown in FIG. 5, the watch 50 provided with the watch band 51 has a ring shape (ring shape), and the main body piece 52 of the watch band 51 is extended to pass the watch 50 to the wrist. After the wristwatch 50 has passed through the wrist, the main body piece 52 of the watch band 51 contracts, and the wristwatch 50 is mounted on the wrist. In this way, unlike a watch that connects both ends of a band-shaped watch band with pins and pin holes, a watch that can be easily worn on the wrist without troublesome mounting work The band was able to offer.

[0003]

[Issues to be solved]

 However, in the case of the conventional watch band 51 as shown in FIG. 5, the extension of the main body piece 52 is also limited. In addition, the main body piece 52 did not extend sufficiently for the size of the hand, making it difficult to pass the wristwatch 50 through the hand. In addition, when the wristwatch 50 is attached or detached, the watch band 51 may be in a state of rubbing hands, so that some people may feel uncomfortable.

[0004] Accordingly, an object of the present invention is to provide a watch band that improves the detachability of a wrist watch and a watch-related technology provided with the watch band, even if the watch band uses a telescopic body piece.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problem, the invention according to claim 1 includes a telescopic main body piece and a fastener formed by folding a plate member. The present invention relates to a watch band that can be attached and detached.

The invention according to claim 2 relates to a wristwatch provided with the watch band according to claim 1.

[0007]

[Action]

 According to the first aspect of the present invention, in addition to the extension of the telescopic body, the fastener formed by folding the plate member is widened, so that the watch band has a sufficient length for passing the watch through the wrist. Then, after passing through the wrist, the elongated main body piece contracts, and the fastener is folded on the plate member so that the wristwatch is mounted on the wrist. Also, by expanding the clasp of the wristwatch attached to the wrist and extending the body piece, the wristwatch can be smoothly removed from the wrist.

[0008] The invention according to claim 2 provides a wristwatch with good detachability from the wrist.

[0009]

[Embodiment of the invention]

 An embodiment of the present invention will be described with reference to the drawings. The drawings used here are FIGS. FIG. 1 is a perspective view showing an embodiment of the present invention. The watch band 10 includes telescoping body pieces 11, 11 and a fastener 12.

The main body piece 11 is configured such that a front box 26 and a back box 27 are connected to each other with a fitting 28 so as to be able to expand and contract in the left-right direction (ever type).

The fastener 12 includes an upper plate 13, a middle plate 14, and a lower plate 15. An edge of the main body piece 11 and one edge of the upper plate 13 are rotatably connected to each other. The other edge of the plate 13 and one edge of the middle plate 14 are rotatably connected, and the other edge of the middle plate 14 and one edge of the lower plate 15 are rotatably connected. The other edge of the lower plate 15 and the edge of the body piece 11 are rotatably connected. Then, the upper plate 13 and the middle plate 14 are folded over the connection portion, and the middle plate 14 and the lower plate 15 are folded.

With the upper plate 13, the middle plate 14, and the lower plate 15, which are the three plate members of the fastener 12, thus folded, the locking projection 18 provided on the lower plate 15 is moved to the lower surface of the upper plate 13. It is inserted into the locking hole 19 provided in the main body. A pair of locking pieces 20 and 23 are provided in the locking hole 19. The locking pieces 20 and 23 have rear ends 21 and 24 protruding from side edges of the upper plate 13, and similarly, front ends 22 and 25 also protrude into the locking holes 19. When the locking projections 18 are inserted into the locking holes 19, the locking projections 18 are locked to the tips 22, 25 in the locking holes 19, and the folded state of the three plate members of the fastener 12 is fixed. Is done. Further, when the rear ends 21 and 24 are pushed in the direction of the locking holes 19, the state in which the tips 22 and 25 protrude from the locking holes 19 is eliminated, and the locking of the locking projections 18 is released.

FIG. 2 is an explanatory diagram showing a state in which a wristwatch 30 including the watch band 10 having such a configuration is worn on a wrist. The wristwatch 30 is usually in a state where the main body piece 11 is contracted and the fastener 12 is closed as shown in FIG. When the user wears the wrist, the user slides his hand through the ring of the wristwatch 30 with the main body piece 11 extended and the fastener 12 spread as shown in FIG. 2 (B). In this case, in addition to the extension of the watch band 11, the fastener 12 is in an expanded state, so that the watch 30 can be passed through the hand without being caught by the hand. The wristwatch 30 passed through the wrist is attached to the wrist by contracting the main body piece 11 and folding and holding the fastener 12 (FIG. 2C).

When the wristwatch 30 is removed from the wrist, the fastener 12 is released by releasing the fastening of the fastener 12, so that the wristwatch 30 can be easily passed from the hand.

As the extendable main body piece 11 of the watch band 10, besides the “ever type” shown in FIGS. 1 and 2, an “S-shaped type” shown in FIG. There is also a "curl type" shown in). However, the extendable main body piece 11 is not limited to this.

As the fastener 12, besides the fastener shown in FIGS. 1 and 2, there is also a “three-folding type” shown in FIG. However, the fastener 12 is not limited to this.

[0017]

[Effect of the invention]

 According to the present invention, in addition to the extension of the telescopic main body piece, by expanding the clasp formed by folding the plate member, the length of the watch band becomes sufficient to pass the ring-shaped wristwatch to the wrist. Then, after passing through the wrist, the elongated main body piece contracts, and the fastener can be attached to the wrist by folding the plate member. In addition, the watch can be removed smoothly from the wrist by expanding the clasp of the wristwatch attached to the wrist and extending the body piece.
