Description

The present invention relates to wristwatch retaining parts.

A wristwatch is made up of a watch body, a clasp, and a pair of bands that connect the watch body and the clasp. A pin is inserted into the band at one end in the width direction of the band. The watch body and the band holding parts of the clasp hold both ends of the pin, so that the band is held by the watch body and the clasp.

Conventionally, a spring bar that can expand and contract using a built-in spring has been used as the pin. In this case, by contracting the spring bar, the end of the spring bar is released from the band holding part, and the band can be removed from the watch body and clasp. However, since a special tool is required to contract the spring bar, it has been difficult for users to freely remove the band and replace the band or clasp.

Patent Document 1 describes a watch case that has a protrusion that protrudes from the edge of the watch and has a groove formed on its upper surface for fitting a pin, and a rotating rim that holds the pin in the groove by covering the protrusion from above with the pin fitted in it. With the watch case in Patent Document 1, the user can easily remove the band from the watch case without using a special tool.

Patent No. 2761987

However, the watch case in Patent Document 1 has a rotating rim around the outer periphery of the watch body, which reduces the freedom of design of the watch.

The present invention was made to solve the above-mentioned problems, and aims to provide a wristwatch retaining component that allows the band to be easily removed while minimizing the impact on the watch's design.

The wristwatch retaining part of the present invention has a pair of retaining parts facing each other and each of which has a groove for locating both ends of a pin that is inserted in the width direction of the watch band, a cover member pivotally supported on one of the retaining parts, and a locking mechanism that fixes the pivoting end of the cover member to the other retaining part, and is characterized in that the retaining parts and the cover member hold both ends of the pin in the groove when fixed.

In addition, in the wristwatch holder of the present invention, it is preferable that the locking mechanism can be released by pushing the rotating end from above.

In addition, in the wristwatch holding part according to the present invention, it is preferable that the locking mechanism can be released by pressing the other holding part from below.

It is also preferable that the wristwatch retaining part according to the present invention has a plate-shaped connecting part below the groove that connects the pair of retaining parts.

It is also preferable that the wristwatch retaining part according to the present invention is joined to the clasp or outer case of the watch.

In addition, in the wristwatch retaining part of the present invention, it is preferable that the fixed end of the cover member has a notch extending from the top to the bottom so that the fixed end is positioned above the groove of one of the retaining parts when the cover member is rotated to open the upper part of the groove of the other retaining part.

The wristwatch retaining component of the present invention allows the band to be easily removed while minimizing the impact on the watch's design.

FIG. 4 is a cross-sectional view of a wristwatch holding part 8. FIG.

Various embodiments of the present invention will be described below with reference to the drawings. Please note that the technical scope of the present invention is not limited to these embodiments, but extends to the claims and their equivalents.

Figure 1 is a perspective view of a wristwatch 1 according to the present invention. Wristwatch 1 has a watch 2, a clasp 3, and a band 4 that connects an exterior case 21 of watch 2 to the clasp 3. Band 4 has a 12 o'clock side band 4a that connects the 12 o'clock side of the exterior case 21 to one end of the clasp 3, and a 6 o'clock side band 4b that connects the 6 o'clock side of the exterior case 21 to the other end of the clasp 3.

The 12 o'clock side band 4a and the 6 o'clock side band 4b are connected to the clasp 3 via wristwatch retaining parts 5 joined to both ends of the clasp 3. The 12 o'clock side band 4a and the 6 o'clock side band 4b are also connected to the outer case 21 via wristwatch retaining parts 5 joined to the 12 o'clock side and the 6 o'clock side of the outer case 21, respectively. However, in FIG. 1, the 12 o'clock side band 4a is shown in a state where it has been removed from the wristwatch retaining part 5 of the outer case 21. The wristwatch retaining part 5 is a part that holds the end of the band 4 and allows the band 4 to be easily removed by the user's operation. The configuration of the wristwatch retaining part 5 will be described below with reference to FIG. 2 to FIG. 5.

Figure 2 is an enlarged perspective view of the wristwatch retaining part 5 in a state where it is joined to the clasp 3 and holds the band 4, and Figure 3 is an enlarged perspective view of the wristwatch retaining part 5 in a state where the band 4 has been removed. For ease of viewing, in Figure 2, the band 4 is shown as if it were transparent, and only the outer edge of the band 4 is shown by a dotted line. Also, in Figure 3, the band 4 is not shown.

The wristwatch retaining part 5 has a pair of opposing retaining parts 51a and 51b (hereinafter, sometimes collectively referred to as retaining parts 51), a cover member 52, a connecting part 53, and a joint part 54. The retaining part 51 and the cover member 52 are members that retain the band 4 by holding both ends of the pin 41 that is inserted in the width direction of the band 4 at the end of the band 4. The joint part 53 is a plate-shaped member that connects the retaining parts 51a and 51b at their lower parts. The joint part 54 joins the wristwatch retaining part 5 to the watch 2 or the clasp 3. The joint part 54 may be joined to the clasp 3 or the watch 2 with an adhesive, or may be joined to the clasp 3 or the watch 2 by being formed integrally with the clasp 3 or the watch 2.

Grooves 511 for arranging both ends (411a, 411b) of the pin 41 are provided on the opposing surfaces of the holding parts 51a and 51b. The cover member 52 has a first cover part 521a that covers the upper part of the groove 511 provided in the holding part 51a, and a second cover part 521b that covers the upper part of the groove 511 provided in the holding part 51b. This allows both ends (411a, 411b) of the pin 41 to be held in the wristwatch holding part 5.

The first lid portion 521a is rotatably supported on the holding portion 51a by a screw 522. The first lid portion 521a and the second lid portion 521b are connected to each other by a lid connecting portion 523. This allows the lid member 52 to rotate with the first lid portion 521a as the fixed end and the second lid portion 521b as the rotating end. By rotating the lid member 52, as shown in FIG. 3, the upper part of the groove 511 of the holding portion 51b is opened, making it possible to remove the band 4 with the pin 41 inserted therethrough.

The first lid portion 521a is provided with a rectangular cutout 525 extending from the upper surface to the lower surface of the first lid portion 521a. As shown in FIG. 3, the cutout 525 is provided so as to be located above the groove 511 of the holding portion 51a when the lid member 52 is rotated to open the upper portion of the groove 511 of the holding portion 51b. This makes it easy to remove the pin 41 when the lid member 52 is rotated. Note that, in the example shown in FIG. 2 and FIG. 3, the cutout 525 is rectangular, but is not limited to such an example. The cutout 525 may be provided in any shape, such as a triangular shape or a D-cut shape, such that the upper portion of the groove 511 of the holding portion 51a is opened when the lid member 52 is rotated.

The wristwatch holder 5 has a locking mechanism 6 that fixes the second cover 521b to the holder 51b. The locking mechanism 6 can be released by pressing the cover button 61 on the top surface of the second cover 521b from above. The locking mechanism 6 will be described below with reference to Figures 4 and 5.

Figure 4 is a cross-sectional view of the wristwatch holding part 5 in a state where the second cover part 521b is fixed to the holding part 51b. Figure 5 is a cross-sectional view of the wristwatch holding part 5 in a state where the cover button 61 is pressed from above and the locking mechanism 6 is released. Note that Figures 4 and 5 are cross-sectional views of the IV-IV section in Figure 2.

The cover button 61 is inserted into the cover button hole 62 that penetrates the second cover 521b from top to bottom. A narrowed portion 621 is formed in the cover button hole 62 so that the inner diameter is smaller at the upper end. A cylinder 622 whose outer diameter is approximately the same as the inner diameter of the cover button hole 62 is press-fitted into the lower portion of the cover button hole 62. A flange 611 is provided on the cover button 61 so that the outer diameter is partially larger. By engaging the flange 611 with the narrowed portion 621 and the cylinder 622, the cover button 61 can slide up and down within a predetermined range such that the top 612 is higher than the upper surface of the second cover 521b.

A holding part button hole 64 for inserting the holding part button 63 is provided on the upper surface of the holding part 51b. A coil spring 641 is arranged on the bottom surface of the holding part button hole 64, and a bearing hole 642 is provided on the axis of the coil spring 641. The holding part button 63 is provided with a shaft part 631 at the bottom, which has approximately the same diameter as the inner diameter of the bearing hole 642, and a flange part 632 is provided above the shaft part 631 so that the outer diameter is larger than the diameter of the coil spring 641. The holding part button 63 is inserted into the holding part button hole 64 so that the shaft part 631 is inserted into the bearing hole 642 and the flange part 632 is placed on the coil spring 641. As a result, the holding part button 63 is pressed upward by the elastic force of the coil spring 641.

A cylinder 643, whose inner diameter is approximately the same as the outer diameter of the flange 632, is press-fitted into the holding part button hole 64. A narrowed portion 644 is provided at the upper end of the cylinder 643 so that the inner diameter is smaller. As a result, the flange 632 of the holding part button 63, which is pressed upward by the coil spring 641, is locked by the narrowed portion 644.

The top 633 of the holding part button 63 has an outer diameter that is approximately the same as the inner diameter of the cylinder 622 inserted into the lid button hole 62. The top 633 is also formed so as to be higher than the upper surface of the holding part 51b when the flange 632 is engaged by the narrowing part 644. As a result, as shown in FIG. 4, the top 633 fits into the cylinder 622 inserted into the lid button hole 62, and the second lid part 521b is fixed to the holding part 51b.

When the cover button 61 is pressed from above, as shown in FIG. 5, the cover button 61 presses the holding button 63, and the flange 611 of the cover button 61 is locked by the cylinder 622. In this state, the top 633 of the holding button 63 is pushed out from the cylinder 622, so the locking mechanism 6 is released and the cover member 52 can rotate around the second cover portion 521b as the rotation end.

A slope is formed on the outer periphery of the top 633 of the holding button 63, connecting the top surface and the side surface. As a result, when the cover button 61 is pressed from above, even if the pressing is not sufficient, the slope is pressed down by the lower end of the cylinder 622, and the cover member 52 becomes rotatable.

When the locking mechanism 6 is released, the second lid portion 521b of the lid member 52 is returned above the holding portion 51b and the top 633 of the holding portion button 63 is fitted into the cylinder 622, thereby fixing the second lid portion 521b to the holding portion 51b and holding the pin. At this time, since a slope 524 is formed between the bottom surface and the portion of the side surface of the second lid portion 521b that contacts the holding portion button 63, the holding portion button 63 is pressed down by the slope 524 in the process of returning the second lid portion 521b above the holding portion 51b. This allows the user to fix the lid member 52 to the holding portion 51b simply by returning the second lid portion 521b above the holding portion 51b, improving user convenience.

As described above, the wristwatch holding part 5 has a pair of holding parts 51a and 51b with grooves 511 for respectively locating both ends (411a, 411b) of the pin 41, and a cover member 52 rotatably supported on the holding part 51a. The wristwatch holding part 5 also has a locking mechanism 6 that fixes the second cover part 521b, which is the rotating end, to the holding part 51b, and when fixed, holds both ends (411a, 411b) of the pin 41 within the groove 511. This allows the wristwatch holding part 5 to easily remove the band 4 while minimizing the impact on the design of the watch 2.

The wristwatch retaining part 5 also has a plate-shaped connecting part 53 below the groove 511 that connects the retaining parts 51a and 51b. This increases the strength of the wristwatch retaining part 5. Note that the wristwatch retaining part 5 does not have to have the connecting part 53. In this case, the retaining parts 51a and 51b may be formed as separate bodies and each may be joined to the clasp 3.

In addition, in the wristwatch holding part 5, the locking mechanism 6 can be released by pushing the second cover part 521b, which is the rotation end, from above. This allows the user to remove the band 4 with a simple operation.

Figures 2 and 3 show a wristwatch retaining part 5 joined to a clasp 3, but when the wristwatch retaining part 5 is joined to an outer case 21, it has the same configuration as described above, except that the joint 54 is joined to the side of the outer case 21.

2 and 4, when the second lid portion 521b is fixed to the holding portion 51b, the top of the lid button 61 protrudes from the upper surface of the second lid portion 521b, but this is not limited to an example. When the second lid portion 521b is fixed to the holding portion 51b, the top of the lid button 61 may be formed to be at the same height as the upper surface of the second lid portion 521b or lower than the upper surface of the second lid portion 521b. This makes it less likely that the user will accidentally press the lid button 61 and release the lock mechanism 6, improving convenience for the user.

In the above description, the locking mechanism 6 can be released by pushing the second lid portion 521b from above, but this is not limited to the example. For example, the locking mechanism may be released by pushing the holding portion 51b from below. Below, a band holding part 8 having such a locking mechanism 7 will be described with reference to FIG. 6. Note that the same reference numerals are used for configurations similar to those described above, and descriptions will be omitted as appropriate.

Figure 6 is a cross-sectional view of the band holding part 8 having the locking mechanism 7. The locking mechanism 7 has a configuration that is roughly the same as the locking mechanism 6 but turned upside down, and has a holding part button 71 that is inserted into a holding part button hole 72 that penetrates the holding part 51b from top to bottom, and a cover part button hole 74 provided on the underside of the second cover part 521b.

The holding part button 71 is provided with a flange 711 so that the outer diameter is partially larger. The holding part button hole 72 is formed with a narrowed part 721 so that the inner diameter is smaller at its lower end. A cylindrical body 722 is inserted into the upper part of the holding part button hole 72. The flange 711 is engaged with the narrowed part 721 and the cylindrical body 722, so that the holding part button 71 can slide up and down within a predetermined range.

A coil spring 741 is disposed on the bottom surface of the cover button hole 74, and a bearing hole 742 is provided on the axis of the coil spring 741. The cover button 73 is inserted into the cover button hole 74 so that the axis 731 is inserted into the bearing hole 742 and the coil spring 741 is placed on the flange 732. A cylinder 743 whose outer diameter is approximately the same as the inner diameter of the cover button hole 74 and whose inner diameter is approximately the same as the outer diameter of the flange 732 is further pressed into the cover button hole 74 with the cover button 73 inserted. A narrowed portion 744 is provided at the lower end of the cylinder 743 so that the inner diameter is reduced. As a result, the flange 732 of the cover button 73 is locked by the narrowed portion 744.

The top 733 of the cover button 73 is formed so that it is lower than the underside of the second cover 521b when the flange 732 is engaged by the narrowing portion 744. This allows the top 733 to fit into the cylinder 722 inserted into the holding button hole 72, and the second cover 521b is fixed to the holding portion 51b.

When the holding part button 71 is pressed from below, the holding part button 71 pushes up the cover part button 73, and the top 733 of the cover part button 73 is pushed out from the cylinder 722, thereby releasing the locking mechanism 7. In this way, the locking mechanism 7 can be released by pressing the holding part 51b from below. This makes it less likely that the user will accidentally release the locking mechanism while wearing the wristwatch 1, improving convenience for the user.

In the above explanation, an example of connecting the wristwatch retaining part of the present invention to the band 4 was described, but the part to be connected is not limited to the band 4. For example, a decorative part decorated with jewels or the like may be connected, and various parts can be easily held and replaced.

Those skilled in the art should understand that various changes, substitutions, and modifications can be made to the present invention without departing from the spirit and scope of the present invention. For example, the processing of each part described above may be performed in a different order as appropriate within the scope of the present invention. Furthermore, the above-described embodiments and modifications may be implemented in combination as appropriate within the scope of the present invention.
