Description of the Related Art As is well known, the reference mechanism of an alarm clock has a reference cam mechanism that controls the start of the reference operation by a cam operation that is interlocked with the operation of the timepiece train, and a set / non-set and stop of the reference operation. It is composed of a silence switch device for controlling. The tip of the operating rod of the silence switch device protrudes outside the watch case, and
By tipping the tip of the operating rod by a switch operator slidably mounted on the watch case,
It is known that a switch is turned on and off.

As an example of the engagement between the switch operating element and the operating rod, as shown in FIG. 9, a tip portion 31 of an operating rod 30 protruding from the watch case 21 is formed in a brim shape, and the switch operating portion is engaged with this. The tapered projection 41 of the child 40 is engaged, the tip 31 of the operating rod 30 is pulled upward in the drawing (see (2) in FIG. 9), and the switch operator 40 slides in the opposite direction. The taper-shaped protruding portion 41
When the operating rod 30 is separated from the tip portion 31 of 0, the operating rod 30 is always urged in the direction of being buried by an elastic body (not shown), and thus returns to the original position again (see (1) in FIG. 9). In this way, the operation rod 30 is projected and retracted by the sliding of the switch operator 40, and the switch is turned on and off.

Further, the switch operator is engaged with a plurality of engaging projections provided on the outer surface of the timepiece case, and the switch is slidably mounted on the timepiece case. As an example, as shown in FIG. 10, the protrusion 32 provided on the watch case has a protrusion 3 at the upper end portion that is orthogonal to the protrusion direction of the protrusion 32.
3 is integrally formed, and the switch operator described above is restricted by the protrusion 33 and held by the watch case.
Incidentally, the protrusion 32 itself may be provided so as to restrict the slide of the switch operator by the protrusion main body.

The mounting of the switch operator on the above-mentioned timepiece case, that is, the switch mounting structure of the timepiece is as follows.
Normally, one switch operator is attached to the watch case. Further, if the shape of the switch operator is different, different protrusions are arranged. Therefore, it is general that a switch operator is provided for this watch case, and a switch is provided for each watch case. Is.

[0006]

As described above, the switch is conventionally determined for each watch case. However, if the inventor of the present application can mount another switch operator having a different shape on one watch case. As a result, the invention of the present application has been devised, considering that it is convenient because the members are commonly used and the products are generalized and diversified.

That is, in this type of switch mounting structure, basically, one operating rod of the reference mechanism is moved in and out by one switch operating element, and the switch operating element has a different shape. When it is changed, it is rational to arrange the layout of the protrusions for holding the switch operators, and it is possible to reduce the manufacturing cost by projecting the minimum necessary protrusions. The purpose is to obtain a possible switch mounting structure for a timepiece.

[0008]

According to the present invention, a plurality of engaging projections are provided on the outer surface of a watch case, and a switch is slidably mounted on the watch case by engaging a switch with these projections. In a switch mounting structure for a timepiece of this type, a plurality of switches that are selectively mounted on the watch case, a predetermined number of protrusions that engage with one of the plurality of switches, and the plurality of switches. And a predetermined number of protrusions that engage with the other one of the switches, and one or a plurality of protrusions of the predetermined number of the two protrusions are shared. .

In the case of such a configuration, usually, the number of protrusions corresponding to the number of switches is required, but the number of protrusions can be reduced by the amount of the protrusions being shared. Therefore, when selectively mounting a plurality of switches on the watch case, it is possible to provide the minimum necessary protrusions so as to project, and it is possible to obtain the switch mounting structure of the watch that can reduce the manufacturing cost. .

In the above, reference numeral 36 denotes a protrusion for regulation when a first switch operator described later slides, and 37 denotes a protrusion for regulation when a second switch operator later described slides.

The timepiece case 1 shown in FIG. 1 is provided with predetermined components in addition to the operating rod 30, the protrusion 32, etc. described above, but only those necessary for explaining the present invention will be described. , Others are not shown.

FIG. 2 is a view showing a state in which a switch operator 40A of a push-and-push type switch is attached to the watch case 1, and FIG. 3 is a side view of the switch operator 40A.

In the case of this example, the switch operator 40A is an operator whose pressing portion projects outward from the side of the watch case 1, and one of the protrusions 32 of the watch case 1 is the first. Engaging with the projection 32a and the third projection 32c, and the opposite side is the fifth projection 32e and the sixth projection 32f.
And is held slidably in the left-right direction. Reference numeral 42 denotes an arm integrally formed with the switch operator 40A. When the tip of the arm 42 contacts the second protrusion 32b, the switch operator 40A is prevented from coming off. In this state, the relationship between the switch operator 40A and the operation rod 30 of the buzzer switch device is shown in FIG.
As shown in (1), the operating rod 30 is a switch operator 40.
Since it is separated from the tapered protrusion 41 of A, the operating rod 30 is in the initial position.

Further, as shown in FIGS. 4 and 5, when the switch operator 40A is pressed and slides to the right in the drawing, it abuts against the regulating projection 36, and the switch operator 40A slides. Suspension regulations are imposed. As shown in FIG. 9 (2), the relationship between the switch operator 40A and the operation lever 30 of the anti-squeeze switch device in this state is as follows.
The tapered protrusion 41 of the switch operator 40A is engaged, and the tip 31 of the operating rod 30 is pulled upward in the drawing. At this time, the switch operator 40A is regulated by the heart-shaped cam 34 and held at the position. Then, when the switch operator 40A is pushed in this state, the regulation of the heart-shaped cam 34 is released, and the elastic force of a coil spring (not shown) causes the switch operator 40A to slide to the left side in the drawing, thereby causing the arm 42 to move. The tip of the abuts against the second protrusion 32b and returns to the initial position. At this time, since the operating rod 30 is constantly urged in the direction of being buried by the elastic body (not shown), it returns to the original position again.

The arm 42 is provided so as to be elastically deformable. Therefore, when the switch operating element 40A is mounted on the watch case 1, the side portion of the switch operating element 40A has the first protrusion 32a and the third protrusion 32a. Protrusion 32c, fifth protrusion 32e
When engaged with the sixth protrusion 32f, the arm 42 abuts on the upper end of the second protrusion 32b and is elastically deformed, so that the mounting of the switch operator 40A is not hindered.

FIG. 6 is a view showing a state in which a switch operator 40B of a slide switch is attached to the back surface of the watch case 1, and FIG. 7 is a view of the switch operator 40B as seen from the side.

In the case of this example, the switch operator 40B is an operator whose pressing portion is mounted on the back surface of the timepiece case 1, that is, does not protrude outward from the side, and the protrusion 32 of the timepiece case 1 is used. Of which, one side is the first protrusion 32a
And the second protrusion 32b and the fourth protrusion 3 on the opposite side.
It is held so as to be slidable in the left-right direction by engaging with 2d. Reference numeral 43 denotes an arm integrally formed with the switch operator 40B. The tip bulging portion 43a of the arm 43 elastically comes into sliding contact with the first protrusion 32a when sliding,
A click feeling is given to the switch operator 40B. still,
In this example, the projection 38 is separately provided on the timepiece case 1 to support the switch operator 40B so that the switch operator 40B slides smoothly.

The arm 43 of the switch operator 40B is formed with a projection 43b projecting in the direction of the operator body, and the projection 43b is formed in the watch case 1 at the initial position of the switch operator 40B shown in FIG. Protrusion 3 for the regulation of
The switch operator 40B is prevented from coming off by coming into contact with 7. The relationship between the switch operator 40B and the operating rod 30 of the noise suppression switch device in this state is shown in FIG.
As shown in (1), the operating rod 30 is a switch operator 40.
Since it is separated from the tapered protrusion 41 of B, the operating rod 30 is in the initial position.

As shown in FIG. 8, when the switch operator 40B is pressed and slides to the right in the figure, the protrusion 43b of the arm 43 abuts against the second protrusion 32b, and the switch operator 40b. 40B slide stop regulation is made. The relationship between the switch operator 40B and the operating rod 30 of the noise suppression switch device in this state is shown in FIG.
As shown in (2), the tapered protrusion 41 of the switch operator 40B is engaged, and the tip end portion 31 of the operating rod 30 is pulled up in the figure. Then, in this state, when the switch operator 40B is pressed leftward in the drawing, the protrusion 43b is formed.
Comes into contact with the projection 37 and returns to the initial position. At this time, the operating rod 30 has the same function as that of the switch operator 40A.
Since it is always urged by the elastic body (not shown) in the burying direction, it returns to the original position again.

In the present example in which the switch operator 40A of the push-and-push type switch and the switch operator 40B of the slide switch are selectively mounted, both switch operators slide in the same direction, and The first to sixth protrusions 32a, 32 of the watch case 1
Switch operator 4 of b, 32c, 32e, and 32f
0A is a protrusion 32a, 32b, 32c other than the protrusion 32d,
32e and 32f are used, and the switch operator 40B uses the protrusions 32a, 32b, and 32d. Therefore, the protrusions 32a and 32b are shared by both operators. Further, since these commonly used projections are provided along the sliding direction of both operators, that is, the conditions are the same, the sharing can be facilitated.

As described above, in the switch mounting structure of this embodiment, since the protrusions are commonly used, the number of protrusions corresponding to the number of switches is usually required, whereas the protrusions are commonly used. The number of protrusions can be reduced accordingly. Therefore, when selectively mounting a plurality of switches on the watch case, it is possible to provide the minimum necessary protrusions so as to project, and it is possible to obtain the switch mounting structure of the watch that can reduce the manufacturing cost. .

In the above-mentioned specific example, two switch operators are used for explanation, but it is possible to selectively use a larger number of switch operators.

[0025]

Since the present invention is constructed as described above and the projections used for the switch mounting structure are commonly used, the number of projections corresponding to the number of switches is usually required. On the other hand, the number of protrusions can be reduced as much as the protrusions are shared. Therefore, when selectively mounting a plurality of switches on the watch case, it is possible to provide the minimum necessary protrusions so as to project, and it is possible to obtain the switch mounting structure of the watch that can reduce the manufacturing cost. It is a thing.
