Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a structure for attaching a watch band that can be freely adapted to the size of the wrist and can be easily attached and detached.

[Conventional technology]

The length of the band attached to a conventional wristwatch is constant to some extent, as the wristwatch is worn directly on the wrist of a person. Even so, taking into account the variation in human body shapes, the length is approximately 1.2 times longer than the length that is sufficient for use by a normal person.

[Problem to be solved by the invention]

However, when you normally wear a watch directly on your wrist, for example, when you are skiing, you wear it over your ski gloves) and want to check the time while skiing. Because the glove is worn on the arm, the circumference of the wrist is usually about 1.
It will be more than three times as large.

In such cases, if you prepare a slightly longer band, you can wear it over ski gloves, but if you are carrying it normally, the disadvantage is that if you do not use a normal length band, there will be too much excess and it will be difficult to wear it. Another drawback is that the band overlaps the watch, making it difficult to read the time.

On the other hand, if bands of different lengths are used for normal carrying and skiing, they must be replaced each time, which is very troublesome.

Also, since the normal watch band length is set based on the greatest common divisor of humans, it is usually a little longer (about 1 or 2 times) so that it is just right for people with thick wrists. If a person with a thick wrist wears a glove and sells a band long enough to wear a watch on top of it, the band will become too long when worn normally by a person with a thin wrist, and the product will be sold as a band. The problem is that it damages the marketability of products.

In order to solve the above-mentioned problems, the present invention has been developed to allow comfortable wearing even if the thickness of the arm changes drastically due to wearing a wristband, etc., and also allows for easy attachment and detachment of the band when putting on and taking off the watch. The aim is to provide a watch band that allows for

[Means to solve the problem]

To achieve the above object, the present invention provides a structure for attaching a watch band for wearing a watch on the wrist, including a watch case having a spring bar support hole at one end for supporting a spring bar; A removable piece having a side hole at one end into which the watch case can be inserted, a band that wraps around the arm, a slit for folding back the middle part of the band, and a case engaging part that is fixed to the other end of the watch case. The length of the band wrapped around the arm can be adjusted using the slit in the removable piece, and the band engages a part of the band with a band stopper that fixes the other end of the band. The present invention is characterized in that a clasp member is provided with a band engaging portion for adjusting the length of the band, and the other end of the band is fixed after adjusting the band length.

8 shown in FIG. 2 is a cross section of the skill.

First, the state in which the watch of this embodiment is worn on the wrist will be explained using FIG.

The band 1 passes through a band passage slit 10a of the detachable piece 10, and a clasp member 6 is fixed to the end 1b. The detachable top 10 is initially fixed to the watch case 5. In this state, the watch case 5 is placed on the arm 8, and the band 1 supported and fixed to the watch case 5 by the spring bar 2 is wrapped around the arm 8, and at the attachment/detachment piece 10, the band is adjusted according to the thickness of the arm 8. Pull the end 1b side of 1 to determine the length of the curl.

Next, fold it back with the detachable piece 10, wrap the cut part around the outside of the already wrapped band 1, and use the clasp member 6 fixed to the end 1b to tie the already wrapped band 1 horizontally like a necktie. The watch case 5 is attached to the arm 8 by further sliding the watch case 5 into engagement.

Next, the state of engagement between the band 1 and the clasp member 6 will be explained using FIGS. 3 and 4.

First, the end 1b of the band 1 is inserted into the band accommodating part 6a of the clasp member 6, and the two screws 4 are screwed into the band accommodating part 6a as shown in the figure. By compressing the distal end 1bl, the distal end 1b is fixed to the band storage portion 6a. The band 1 is inserted into the band engaging portion 6b of the clasp member 6 and held by the spring 6. Therefore, when removing the clasp member 6 from the band 1, it can be removed by shifting it in the direction of arrow E shown in FIG.

As described above, by engaging the clasp member 6 at an appropriate position of the band 1 according to the diameter of the arm 8, the diameter of the arm 8 can be easily and freely adjusted whether it becomes thicker or thinner. You can adjust the length of band 1.

As is clear from this, the adjustable width of the winding length of the band 1 can be twice as long as the minimum winding length.

By the way, each time you want to remove the watch from the wrist 8, you have to remove the clasp member 6 from the band 1 and remove the watch from the wrist 8 through the back of the hand.
This is troublesome. Therefore, a means for easily removing the watch from the position where it is worn on the wrist 8 is also incorporated into this embodiment.

As shown in FIGS. 1 and 2, the removable piece 10 shown in double dotted lines indicates that the watch case 5 has also been removed (in the direction of arrow F).

FIG. 5 is an explanatory diagram showing the operating state of the detachable top as seen from the arrow C-C in FIG. 1, and FIG.

The operation of the detachable top 10 will be explained using FIGS. 5 and 6.

In FIG. 5, the band 1 is the detachable piece 10 as described above.
The band passage slit 10 is surrounded by two bridges, namely the bridge 1 part 10b and the bridge part ■ 10C.
It passes through a and is folded back.

The case engaging protrusion 10e at the tip of the detachable piece 10 engages with the detachable piece engaging groove 5b formed in the watch case 5, and the groove width on the upper surface side of the detachable piece engaging groove 5b of the watch case 5. is smaller than the major axis of the case engaging protrusion 10e,
When the removable top 10 is in position (7), the watch case 5 will not fall off.

Also, the removable top 10 is rotated in the direction of arrow G (a).
When the state is reached, the bridge 1 part 10b' is attached to the watch case 5.
Rotation is regulated by hitting the wall surface 5e of.

Therefore, in the normal state, it is possible to freely rotate between the state (7) and the state (a).

Next, to explain when you want to remove the watch case 5 with the detachable top 10, as shown in FIG. 5, rotate the detachable top 10 in the direction of arrow H and lift it upward.
First, when you rotate the detachable top 10 upward, the detachable top 10
The short diameter of the case engaging protrusion 10.d' matches the width direction of the upper surface side groove of the watch case 50 detachable top engaging groove 5b, and the width of the case engaging protrusion 10d' is narrower. It is now in a state where it can be easily removed from the groove width portion on the upper side of the groove 5b. However, in order to prevent it from coming off easily just by rotating, the removable top engaging groove 5b of the watch case 5 is different in depth, as shown in FIG. It's getting shallower.

Therefore, by rotating the removable top 10 upward and pulling it up by applying force upward, as shown in FIG.
The case engaging protrusions 10e on both sides expand in the direction of arrow J and become 10♂ as shown by the two-dot chain line, and the watch case 5 also separates. In this way, when the detachable top 10 is rotated upward and pulled up with some force, the detachable top 10 is removed from the watch case 5, and as shown in FIGS.
The detachable piece 10' is now in the state shown by the two-dot chain line in the figure.

On the other hand, when installing, you need to apply some force to remove it = I'110
After inserting it into the removable top engaging groove 5b of the watch case 5, it is sufficient to rotate it in the direction of the arrow G shown in FIG.

The method of attaching and detaching the detachable top 10 of this embodiment is to rotate the detachable top 10 upward and then pull it out by applying force. Of course, it is possible to attach and remove the detachable piece 10 even if the detachable piece engaging groove 5b is not stepped.
