Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a diagram showing an external configuration of a wristwatch 1 according to an embodiment of the present invention. The wristwatch 1 includes a timepiece main body 10 that displays time and a band 20 that is connected to both ends of the timepiece main body 10. The timepiece main body 10 is configured such that a timepiece display unit 12 is built in a timepiece case 11 formed of stainless steel, titanium, or the like. In the present embodiment, the wristwatch that displays the time in an analog manner is exemplified, but a wristwatch that digitally displays the time may be used.

The band 20 is configured by connecting a large number of pieces 21 made of a metal material such as stainless steel or titanium, and is connected to a portion called a can of the watch case 11 of the watch body 10. The band 20 is composed of an upper band 20A and a lower band 20B. The upper band 20A and the lower band 20B are engaged with a not-shown middle ring in order to fasten the wristwatch 1 to a wearing part (wearer's wrist). It has been stopped.
Of the pieces 21 of the upper band 20A and the lower band 20B, the pieces 21A and 21B connected to the watch case 11 are provided with decorative pins 30 simulating screw-type connecting pins. In practice, the band 20 and the watch case 11 are connected to the projections 11A and 11B integrally formed at both ends of the watch case 11 by connecting pins 40 such as spring bars (indicated by a wavy line in FIG. 1). Is inserted, and both ends of the connecting pin 40 are fitted into the pieces 21A and 21B.

An insertion hole (first hole) 50 for inserting the decoration pin 30 is formed on both sides of the piece 21A, and holes 51 into which both ends of the connection pin 40 are fitted so as to communicate with the insertion hole 50 are formed. Is formed. Since the piece 21B is formed in the same manner as the piece 21A, the detailed description thereof is omitted.

Next, a method for fixing the decorative pin 30 will be described. In the following description, the case where the decoration pin 30 is fixed to the piece 21A will be described in detail, but the same applies to the case where the decoration pin 30 is fixed to the piece 21B.
First, the decoration pin 30 is inserted into the insertion hole 50 of the piece 21A. Here, the knurled portion of the decoration pin 30 and the insertion hole 50 are formed in a tight fit, and the decoration pin 30 is fitted into the insertion hole 50 by driving the decoration pin 30.

  Next, as shown in FIG. 4, from the back side of the piece 21 </ b> A, specifically, from the wrist side surface that is the attachment site of the band 20, the bag hole ( (Second hole) 52 is opened, and a rod-like pin 60 having substantially the same diameter as the bag hole 52 is driven into the bag hole 52. As a result, both ends of the pin 60 penetrating the decorative pin 30 are positioned in the bag hole 52, and the decorative pin 30 is prevented from coming off. After the rod-shaped pin 60 is driven, the rod-shaped pin 60 is prevented from coming off by striking the inlet of the bag hole 52 with a predetermined member (see symbol α in FIG. 4). As a result, the rod-shaped pin 60 and the decoration pin 30 are fixed to the piece 21A without coming off.

  As described above, the insertion hole 50 for inserting the decoration pin 30 is provided on the side surfaces of the pieces 21A and 21B. After the decoration pin 30 is inserted into the insertion hole 50, the bag hole 52 penetrating the shaft of the decoration pin 30 is formed. The decorative pin 30 is provided by driving the pin 60 into the bag hole 52 to prevent the decorative pin 30 from being removed, and by fixing the decorative pin 30 by crimping the inlet of the bag hole 52 to prevent the decorative pin 30 from being removed. I can. For this reason, even if a rotational force or a pulling force is applied to the decoration pin 30 from the outside, the decoration pin 30 does not come off. Moreover, there is no restriction | limiting of the material of the decoration pin 30 and the pieces 21A and 21B like the case of brazing, and various metal materials and resin materials can be applied. Further, since the bag hole 52 is opened from the back side of the pieces 21A and 21B, the bag hole 52 is not visible when the wristwatch 1 is worn on the wrist, and the appearance is not impaired.

The above-described embodiments merely show one aspect of the present invention, and can be arbitrarily modified within the scope of the present invention. Hereinafter, each modification will be described.
In the above-described embodiment, the case where the pin 60 is prevented from coming off by crimping the inlet of the bag hole 52 has been described, but the spring pin 61 may be driven in place of the pin 60. Since the spring pin 61 itself expands and contracts in the circumferential direction due to elastic deformation, when the spring pin 61 is driven into the bag hole 52, it is difficult to remove from the bag hole 52 due to its elastic force. For this reason, the step of caulking the inlet of the bag hole 52 can be omitted.

  The spring pin 61 may be used as a general spring pin shown in FIG. 5A, but as shown in FIG. 5B, the diameter of the end portion is made smaller than the diameter of other portions. It is more preferable to use a spring pin 61A made of a ring-shaped elastic member in which a zigzag gap 62 is formed in the axial direction. According to this spring pin 61A, since the diameter of the end portion is smaller than the diameter of the other portion, it becomes easy to insert the spring pin 61A straight into the bag hole 52, and the spring pin 61A When contracted, the opposing member 61A1 and member 62A2 mesh with each other through the gap 62, so that the spring pin 61A can be stably held in the bag hole 52 without shifting in the axial direction.

6 is a view showing a decorative pin 301 according to another modification, FIG. 7 is a plan view of a piece 21A1 according to this modification, and FIG. 8 is a view showing a BB cross section of the piece 21A1. As shown in FIG. 6, the decorative pin 301 has a tip end portion 303 that is thinner than the knurled portion 302.
As shown in FIGS. 7 and 8, the piece 21 </ b> A <b> 1 has a stepped hole as the insertion hole (first hole) 501 of the decorative pin 301, specifically, substantially the same as the knurled portion 302 of the decorative pin 301. A hole 501A having a diameter, and a hole 501B having substantially the same diameter as the tip 303 are formed in advance. In addition, a bag hole (second hole) 511 that penetrates the hole 501B substantially vertically from the back side of the piece 21A1 is formed in advance.
When the decoration pin 301 is fixed to the piece 21A1, the decoration pin 301 is driven into the insertion hole 501, and then a predetermined rod member (deformation member) β is driven from the bag hole 521 into the insertion hole 501. A part of the tip 303 of the inserted decoration pin 301 is deformed in the axial direction of the bag hole 521. As a result, the decorative pin 301 cannot be removed, and the decorative pin 301 can be simply and firmly fixed as in the above embodiments.

  In the above-described embodiment, the case where the bag holes 51 and 52 are formed in a direction substantially perpendicular to the insertion holes 50 and 501, respectively, has been described. However, the bag holes 51 and 52 can be opened from the back side of the pieces 21A and 21A1. What is necessary is just to open diagonally. In the above-described embodiment, the case where the decoration pin is fixed to the piece 21 has been described, but it is needless to say that the present invention can also be applied to the case where the decoration pin is fixed to the timepiece body 10. Further, the present invention can be widely applied not only to a watch but also to a case where a decoration pin is fixed to an accessory such as a bracelet (decoration pin fixing body).
