Description

The present invention relates to a wristwatch band.

Generally, wristwatch bands are made of metal, leather, synthetic resin, or the like. The metal band has a structure in which metal pieces are connected using pins, springs, or the like. The leather band uses animal skin. Furthermore, the synthetic resin is made of synthetic resin to resemble leather.
The ends of these wristwatch bands are attached to the watch case with spring bars.
Japanese Patent No. 2819399 No. 7-41367 Utility model registration No. 3038253

The problem to be solved is that in the various bands as described above, there is a problem that the band marks are red on both sides of the arm (the side on the thumb side of the arm and the side on the little finger side).
Conventional wristbands take time to adapt to the shape of the arm, so it is considered that the band mark sticks to the arm.

On the other hand, a wristwatch band has been proposed in which a core material of a shape memory alloy, which is fixed in a substantially C shape in advance, is embedded.
However, since the shape memory alloy has a spring property, it always presses the wrist of the person who uses the wristwatch. In addition, since it takes time to become a shape that fits the user's arm, the band mark appears as if the watch is lifted by the arm.

A flexible first band portion having one end portion attached to one end side of the watch case, and one end portion attached to the other end side of the watch case and the other end portion to the other end portion of the first band portion. A wristband having a flexible second band portion to which the first and second band portions are connected, and the first and second band portions have flexibility and a property of holding the bent shape. A long shape-retaining material having the above is embedded along the longitudinal direction of the first and second band portions.
The shape retaining material is disposed along both sides of the user's arm when the first and second band portions are wound around the user's arm.
In the first and second band portions, a plurality of the rod-like shape holding members are arranged in parallel.
A first band portion having one end portion attached to one end side of the watch case; a second band portion having one end portion attached to the other end side of the watch case; and the first and second band portions. A wristwatch band having a connecting portion for connecting the other end portions, wherein the first and second band portions are inserted into the through-hole formed through the through-hole of the top and connect a plurality of the tops. The shape holding material is flexible and has the property of holding the shape in a bent state.

According to the wristwatch band of the present invention, a long shape holding material having flexibility and holding the shape of the bent state is embedded in the first and second band portions, or has flexibility. Since the first and second band portions are formed by connecting a plurality of frames with a thread-like shape holding material having a property of holding and bending the wristband, the wristband is attached to the user's arm. When worn on the wristwatch, the wristwatch band has a shape that matches the curvature of the user's arm. Accordingly, when the wristwatch band of the present invention is attached, the wristwatch band is fastened to the entire arm of the user, so that a feeling of fitting is increased and it is difficult to make a band mark.

Further, since the shape of the arm of the user is maintained, it is difficult to fall off the arm when wearing the wristwatch band.

As a result of examining the prior art and its problems in detail, the present inventor has completed the present invention through the following process.

<Watchband 1>

FIG. 1 is a perspective view showing a wristwatch band 1 according to Embodiment 1 of the present invention, and FIG. 2 is a side view showing the wristwatch band 1.
The wristwatch band 1 includes a first band portion 5 having one end portion attached to one end side of the watch case 3 and one end portion attached to the other end side of the watch case 3 and the other end portion of the first band portion 5. The second band portion 7 is connected to the other end portion.

The first band portion 5 is made of a flexible material such as leather or synthetic resin, and is formed by bonding the front leather 9 and the back leather 11 together with an adhesive or stitching. ing. A plurality of holes 13 are formed in the first band portion 5 along the longitudinal direction.

Between the front leather 9 and the back leather 11, a plurality of rod-like shape retaining materials 15 are embedded in parallel. In addition, when the wristwatch band 1 is worn, the shape retaining member 15 is disposed along one side of both sides of the user's arm portion and is embedded in the first band portion 5.

The second band portion 7 is formed in a band shape from a flexible material such as leather or synthetic resin, and is formed by bonding the front leather 17 and the back leather 19 together with an adhesive or stitching. ing. One side 23 of the annular support frame 21 is attached to the tip of the second band portion 7, and the base portion of the engagement pin 25 is rotatably held on the one side 23. The first band part 5 and the second band part 7 are connected by engaging an engagement pin 25 in a desired hole 13 of the first band part 5.
Moreover, the length of the wristwatch band 1 can be adjusted by selecting the hole 13 for engaging the engagement pin 25 among the plurality of holes 13.

Further, a plurality of the rod-like shape retaining materials 15 are embedded in parallel between the front leather 17 and the back leather 19 of the second band portion 7. Further, when the wristwatch band 1 is worn, the shape retaining material 15 of the second band portion 7 is arranged along the other side of both sides of the user's arm portion and is embedded in the second band portion 7. ing.
<Shape retaining material 15>

The shape retaining material 15 was developed by Mitsui Chemicals and is sold as “Techno Roto”. The shape retaining material 15 is said to be a “wire made of resin” and can be easily deformed like a metal wire and can retain the deformed shape.
Since the shape holding member 15 has the above-described properties, when the wristwatch band 1 is attached to the user's arm, the wristband 1 becomes a shape that matches the curvature of the user's arm. Accordingly, when the wristwatch band 1 of the present invention is mounted, the wristwatch band is tightened on the entire user's arm, so that the fit feeling is increased and the band mark is less likely to be attached.

<Watchband 100>

FIG. 3 is a plan view showing a wristwatch band 100 according to Embodiment 2 of the present invention.
The wristwatch band 100 includes a first band portion 105 having one end portion attached to one end side of the watch case 103, a second band portion 107 having one end portion attached to the other end side of the watch case, and first and second bands. In this example, the connecting portion is connected to the first connecting portion 108 connected to the other end portion of the first band portion 105. The second connecting portion 109 is connected to the other end portion of the second band portion 107.
In the first and second band portions 105 and 107, a substantially rectangular frame 113 having two through holes 111 is arranged as shown in FIG. 3, and a thread-like shape retaining material 115 is placed in these through holes 111. And the end of the shape retaining material 115 is connected. The rectangular frame 113 is a frame described in Japanese Patent Application Laid-Open No. 2005-40375 of the same applicant.
