An embodiment of the present invention will be described with reference to the drawings.
1 and 2 illustrate a first embodiment of a fitting structure (hereinafter referred to as “fitting structure”) between a watch case and a watch band according to the present invention.
First, the perspective view of FIG. 1 will be described. The fitting structure 10 includes a concave fitting portion 30 for attaching a watch band formed on the watch case, and a convex end piece 20 fitted to the fitting portion 30 provided at the end of the watch band. It consists of and. And the fitting part 30 and the end piece 20 are connected by the connection pin 40 penetrated in the width direction of a timepiece band. The connecting pin 40 is provided with a groove 41 that is partially thinned in the circumferential direction. Further, the back surface 21 of the end piece 20 is provided with a recess 22 formed so as to be connected to a pin hole formed in the end piece 20 in order to allow the connecting pin 40 to pass therethrough. The recess 22 includes a silicon ball 50 as an urging member and a pin fixing part 60.

  Next, the sectional view of FIG. 2 will be described. FIG. 2 is a longitudinal sectional view of a state in which the watch band (end piece 20) is attached to the watch case (fitting portion 30) using the connecting pin 40. FIG. As shown in the figure, the connecting pin 40 passes through the pin hole formed in the end piece 20 and the fitting portion 30. And the groove part 41 of the connection pin 40 is just located in the recessed part 22 formed in the back surface 21 of the end piece 20, and has also penetrated the through-hole 61 of the pin fixing part 60 with which the recessed part 22 was equipped. At this time, the pin fixing part 60 is urged toward the opening of the recess 22 by a silicon ball 50 as an urging member provided at the bottom of the recess 22. As a result, the through hole 61 of the pin fixing part 60 and the groove 41 of the connecting pin 40 are locked, and the connecting pin 40 is fixed in the pin hole.

  In addition, the connecting pin 40 presses the pin fixing part 60 toward the bottom side of the recess 22, so that the locking state of the through hole 61 of the pin fixing part 60 and the groove 41 of the connecting pin 40 is eliminated, so that the pin hole can be easily removed. Can be removed. And once the connecting pin 40 is removed, the pin fixing part 60 can be easily inserted into the pin hole by pressing the pin fixing part 60 toward the bottom side of the recess 22 again. That is, it is possible to create a state where the through hole 61 of the pin fixing part 60 and the groove 41 of the connecting pin 40 are locked again.

  From the above, since the connecting pin 40 can be easily removed and attached without using a special tool, it is easy to detachably attach the watch band to the watch case. Further, while the watch band can be easily attached to and detached from the watch case, the through hole 61 of the pin fixing part 60 and the groove 41 of the connecting pin 40 are securely locked in the pin hole, so that the connecting pin 40 falls off naturally. Since this can be prevented, the attachment state of the watch case (fitting part 30) and the watch band (end piece 20) can be stably maintained.

  In addition, when inserting the connecting pin 40 into the pin hole, it is necessary to also insert the through hole 61 of the pin fixing part 60, but since the direction of the through hole 61 cannot be confirmed in the state of being inserted into the recess 20, There is a possibility that the pin hole and the through hole do not match (in this case, the connecting pin 40 cannot be inserted). For this reason, as shown in FIG. 1, a mark 62 indicating the direction of the through hole 61 is provided on the outer surface of the pin fixing part 60, and the direction of the through hole 61 can be confirmed (viewed) in a state inserted in the recess 20. It is good to do so.

FIG. 3 is a sectional view showing a second embodiment of the fitting structure according to the present invention.
The second embodiment shown in FIG. 3 differs from the first embodiment shown in FIGS. 1 and 2 in that a pressing spring 51 is used as a biasing member that biases the pin fixing part 60 toward the opening of the recess 22. That is. By providing the pressing spring 51 at the bottom of the recess 22, the pin fixing part 60 is urged toward the opening side of the recess 22 as in the first embodiment, and the through hole 61 of the pin fixing part 60 and the connecting pin 40 are connected. The groove 41 is locked, and the connecting pin 40 is fixed in the pin hole. Since the second embodiment is the same as the first embodiment except that the pressing spring 51 is used as the biasing member, the description thereof is omitted (the same reference numerals as those in the first embodiment are used). .

In addition, you may add a change or a structure to the following structures not only in 1st Embodiment and 2nd Embodiment illustrated in FIGS. 1-3.
(1) Instead of the back surface 21 of the end piece 20, a recess may be formed on the front surface side.
(2) Instead of the end piece 20, a recess may be formed on the back surface or the front surface of the fitting portion 30.
(3) Instead of the silicon ball 50 or the push spring 51 as the biasing member, any elastic body having a biasing action may be used.
(4) The pin fixing part 60 may be prevented from falling out of the recess 20 by squeezing (crimping) the opening of the recess 20 (in a state of not being locked with the connecting pin 40).

4-6 is explanatory drawing which shows the usage example of this invention.
As described above, the present invention can be attached to the watch case easily and detachably. Therefore, the present invention is convenient when the user has a plurality of watch bands and frequently uses the watch bands. For example, as shown in FIG. 4, by using the common end piece 20, it is possible to remove the metal belt that has been attached so far and attach the leather belt to the same watch case. Enabling the interchange of metal belts and leather belts is extremely innovative. 5 shows a state in which a metal belt is attached to the watch case, and FIG. 6 shows a state in which a leather belt is attached to the watch case.

  The present invention can be widely used as a fitting structure between a watch case and a watch band in which the watch band can be easily attached to and detached from the watch case.
