Abstract

PROBLEM TO BE SOLVED: To provide a clock capable of easily performing mode discrimination in a clock movement state in a clock with a chronograph of a type which can switch a normal time mode and a chronograph, electrically performs drive control of a chronograph pointer and mechanically performs return-to-zero to an initial position.SOLUTION: A plurality of levers operating when modes are switched and configured in a chronograph mechanism are used. Since the levers cannot be visually recognized because a mandarin duck operation hole does not overlap the levers in a planar view in a normal time mode. On the other hand, the levers can be visually recognized because the mandarin duck operation hole overlaps the levers in a planar view in a chronograph mode. Then, mode discrimination can be easily performed by confirming the mandarin duck operation hole. Further, a winding stem cannot be removed because the levers close the mandarin duck operation hole in the chronograph mode.

Description

  The present invention relates to a structure that improves the reliability of a timepiece, such as an improvement in the accuracy of hands with a timepiece that can switch between a normal time mode and other function modes such as a chronograph.

Conventionally, there is a chronograph timepiece of a type in which a chronograph hand is electrically driven and controlled in a chronograph timepiece and is mechanically returned to an initial position.
A chronograph wheel constituting a chronograph wheel train of this type of watch is composed of a chronograph gear, a chronograph true, a heart cam, and the like, and a chronograph hand is attached to a tip of the chronograph true. A plurality of levers are configured in the chronograph mechanism, and a heart cam is rotated by operating a hammer as a part of the lever, and the chronograph hands are returned to an initial position.

Among chronograph watches, there are watches that switch between the normal time mode and the chronograph mode. This type of timepiece has an operating cam interlocked with an external operation member, and this operating cam also interlocks with a lever configured in the chronograph mechanism. For example, when switching from the normal time mode to the chronograph mode, by operating the external operation member, the start / stop transmission lever which is a part of the lever constituting the chronograph mechanism moves to a position interlocked with the start / stop lever. On the other hand, the hammer is released and the restriction of the chronograph wheel is released. Conversely, when switching from the chronograph mode to the normal time mode, the start / stop transmission lever is moved to a position where it cannot be interlocked with the start / stop lever by operating the external operation member. On the other hand, the hammer moves to a position that limits the initial chronograph wheel. (See above, Patent Document 1)
In addition, it is well known that it is indispensable to perform a winding stem operation such as attaching / detaching the winding stem when attaching a watch to a completed movement in the timepiece manufacturing process.
For example, Patent Document 2 discloses that the winding stem is detached by pushing one end of the mandarin duck and releasing the groove engaging portion of the winding stem. The watch movement is operated by the mandarin duck for detaching the winding needle. Space is provided.

JP 61-83991 A Japanese Utility Model Publication No. 61-26941

  As described above, the chronograph hands are electrically driven and controlled, and the chronograph timepiece is mechanically returned to the initial position, and the timepiece that switches between the normal time mode and the chronograph mode is used to complete the movement. When attaching the chronograph hand, it must be performed in the normal time mode in the heart cam zero state. This is because the heart cam is released in the chronograph mode, and the heart cam becomes unstable even when the chronograph is not started. This is because when the needle attachment is performed in such a state, the angular position of the heart cam and the small needle may be shifted.

However, in the prior art, it is not easy to distinguish between the normal time mode and the chronograph mode in the completed movement state, and it is feared that the operator performs the needle attachment in the wrong mode. In addition, in the case of after-sales service (hereinafter referred to as “AS”) at the time of a clock failure, when an outsider of the manufacturer performs needle attachment, there is a greater concern about performing the needle attachment in an incorrect mode.
SUMMARY OF THE INVENTION An object of the present invention is to provide a timepiece that can easily check a normal time mode and a chronograph mode and is structurally limited so that hands cannot be attached in an incorrect mode.

In order to solve the above problems, the present invention provides:
In a movement for a multi-function watch capable of switching between the first mode and the second mode,
An operated component that can be operated in the first mode and cannot be operated in the second mode;
In the first mode, it does not overlap the operated part,
In the second mode, it has an operating part having an overlapping portion that overlaps with the operated part, and the operated part causes the operated part to be
Operation is possible in the first mode, and operation is impossible in the second mode.

  Moreover, it has the opening which can operate the said to-be-operated component in the location corresponding to the said overlap part, It is characterized by the above-mentioned.

  According to the present invention, it is possible to easily confirm the first mode such as the normal time mode and the second mode such as the chronograph mode in the movement state where the hands are not attached. Further, it is structurally impossible to attach and detach the winding stem in the second mode such as the chronograph mode. As described above, the attachment of the pointer is surely performed in the first mode such as the normal time mode, and the needle attaching accuracy of the pointer can be improved.

At this time, the hour hand 3 and the minute hand 4 move in the same manner when the chronograph is not started, and indicate the time. FIG. 2 shows the state of the pointer in the stop state.

As is obvious from FIGS. 1 and 2, the chronograph-equipped timepiece 100 of the present embodiment is a mode indicating whether it is in the normal time mode, the chronograph mode, or the run, stop, or reset state in the chronograph mode. Has no mark or mode pointer.
Therefore, in the completed watch state with hands, it is possible to distinguish between the normal time mode and chronograph mode, or the run, stop, and reset states in the chronograph mode, but in the movement state without the hands, the display side Even if it sees, the distinction is impossible.

  The design of the chronograph timepiece 100 shown in FIGS. 1 and 2 is an example. In addition to those shown here, for example, the barrel 1 may be square instead of round, and the presence / absence, number, and arrangement of the crown 11 and the operation buttons 12 are arbitrary. In the present embodiment, the pointer indicating the elapsed time of the chronograph is the second hand 5, which is also used as the second chronograph hand, the hour chronograph hand 6, the minute chronograph hand 7, the 1/10 second chronograph hand 8, 1 / 100 second chronograph hand 9 and 1/1000 second chronograph hand 10, but not limited to this, even if the 1/1000 second chronograph hand 10 is omitted, chronographs showing other accuracy You may add a graph hand.

Next, the movement structure of the chronograph timepiece 100 of this embodiment will be described.
FIG. 3 is a schematic view of the internal configuration of the chronograph timepiece movement 200 according to the present embodiment when viewed in the normal time mode from the back cover side, and FIG. 4 is a cross-sectional view taken along line AA of FIG. It is. FIG. 5 is a perspective view of a battery support frame retainer 27 described later in order to facilitate understanding of the internal configuration of the timepiece movement with chronograph 200 in the normal time mode according to the present embodiment.

3 and the following plan views are plan views as seen from the back surface side opposite to the pointer side shown in FIGS.
3, 4 and 5, 12a is an operation button for switching between the normal time mode and the chronograph mode, 12b is an operation button for starting / stopping the chronograph, and 12c is an operation button for resetting the chronograph.
14 is a winding stem to which the crown 11 is attached, 15 is a setting lever for operating to remove the winding stem 14, 15a is a recess provided in the setting lever 15 to improve operability when removing the winding stem, and 16 is An operation lever linked to the operation button 12a, 17 an operation cam, and 18 a chronograph operation lever spring for returning the operation button 12a for switching between the normal time mode and the chronograph mode to the initial position. 19 is a switching lever, 20 is a hammer (1), 21 is a hammer (2), 22 is a start / stop transmission lever, 22a is a tip of a start / stop transmission lever 22, and 23 is a start / stop lever. It is a part of the parts constituting the chronograph mechanism. A heart cam (1) 24 is press-fitted and fixed to a chronograph true (1) (not shown), and the chronograph true (1) and the minute chronograph hand 7 are fixed to each other. A heart cam (2) 25 is press-fitted and fixed to a chronograph true (2) (not shown), and the chronograph true (2) and the hour chronograph hand 6 are fixed. Reference numeral 26 denotes a base plate, 27 denotes a metal battery support frame press for holding a battery (not shown), and 27a denotes a setting operation hole provided in the battery support frame press 27 for operating the setting.

  As shown in FIGS. 3, 4, and 5, in the normal time mode, the recess 15 a and the tip 22 a of the start / stop transmission lever 22 do not overlap in the setting operation hole 27 a in plan view. Therefore, the setting lever 15 can be operated through the setting operation hole 27a, and the winding stem 14 can be removed.

Next, a mechanism for switching from the normal time mode to the chronograph mode will be described below with reference to FIGS. FIG. 6 is a schematic view of the internal configuration of the chronograph timepiece movement 200 according to the first embodiment of the present invention in the chronograph mode as viewed from the back cover side. 7 is a cross-sectional view taken along line BB in FIG. FIG. 8 is a perspective view of the battery support frame holder 27 in order to facilitate understanding of the internal configuration of the chronograph timepiece movement 200 according to the first embodiment of the present invention in the chronograph mode.
In the normal time mode of FIG. 5, when the operation button 12a for switching between the normal time mode and the chronograph mode is pressed, the operation lever 16 is pressed and moved, and the operation cam 17 meshing with the operation lever 16 rotates in conjunction with it. Then, the switching lever 19 engaged with the operating cam 17 also moves in conjunction with it, and the start / stop transmission lever 22 engaged with the pin of the switching lever 19 operates in conjunction with the start / stop lever 23 shown in FIG. Move and you can use the chronograph.

  In the chronograph mode of FIG. 6, the hammer (1) 20 and the heart cam (1) 24, the hammer (2) 21 and the heart cam (2) 25 are in a separate positional relationship, and the heart cam (1) 24 and The heart cam (2) 25 is in an unstable state. In this state, when the chronograph needle 7 is engaged with the heart cam (1) 24 and the chronograph needle 6 is engaged with the heart cam (2) 25, each heart cam and each pointer It is feared that the angular position of will shift. Therefore, styling in chronograph mode must be avoided. Therefore, in the chronograph mode, it is desirable to prevent the winding stem operation such as winding stem attaching / detaching necessary when attaching the needle from being performed.

  As shown in FIGS. 6, 7, and 8, in the chronograph mode, in the setting operation hole 27 a, the recess 15 a and the tip 22 a of the start / stop transmission lever 22 overlap in a plan view. Accordingly, the setting lever 15 cannot be operated through the setting operation hole 27a, and the winding stem 14 cannot be removed. Accordingly, it is possible to prevent the winding stem 14 from being erroneously removed in the chronograph mode.

Further, as can be seen from FIGS. 3 and 6, in the normal time mode, the tip 22a of the start / stop transmission lever 22 cannot be seen through the setting operation hole 27a, whereas in the chronograph mode, the start / stop transmission lever 22 is transmitted through the setting operation hole 27a. Is clearly visible. Accordingly, the mode of the chronograph timepiece 100 can be recognized by visually recognizing the inside of the setting operation hole 27a.
For example, in the stylusing operation, the mode is determined by visually recognizing the setting operation hole 27a. If the chronograph mode is selected, the mode is changed to the normal time mode and then the stylusing operation is performed. It is possible to prevent misalignment of the pointer position.

  As described above, the present invention utilizes the movement of the start / stop transmission lever 22 configured in the chronograph mechanism, and in the chronograph mode, the start / stop transmission lever 22 covers the setting lever 15 in the setting operation hole 27a. It is a thing. As a result, it is possible to easily distinguish the modes visually, and in the chronograph mode, it is possible to obtain an effect of restricting unwinding of the winding stem structurally.

  In addition, although it is supplementary, in this embodiment, the battery support frame retainer 27 has confirmation holes 27b in the connecting portion of the switching lever 19 and the start / stop transmission lever 22, and 27c in the operating cam 17; , 27c can also check the mode.

[Second Embodiment]
In the first embodiment, “parts that operate at the time of mode switching are used.
The following embodiment is also conceivable when using a mechanism that hides the part C in the mode B.

FIG. 9 is a perspective view of a battery support frame retainer 127 described later in order to facilitate understanding of the internal configuration of the chronograph timepiece movement 300 according to the second embodiment of the present invention in the normal time mode. In addition, the same number is attached | subjected about the component same as an already-described component, and description is abbreviate | omitted.
28 is a circuit board, 28a is an inspection terminal for performing an inspection relating to the normal time mode in the timepiece movement state arranged on the circuit board 28, 122 is a start / stop transmission lever, 122b is a bulging portion of the start / stop transmission lever 122, 127 Is a battery support frame holder, and 127d is an inspection terminal operation hole provided to operate the inspection terminal on the battery support frame holder 127. These are modified and added as compared with the first embodiment. 10 is a cross-sectional view taken along the line CC of FIG.

As shown in FIGS. 9 and 10, in the normal time mode, in the inspection terminal operation hole 127d, the inspection terminal 28a and the bulging portion 122b of the start / stop transmission lever 122 do not overlap in plan view. Accordingly, the inspection terminal 28a can be operated through the inspection terminal operation hole 127d, and the inspection relating to the normal time mode can be performed in the timepiece movement state.
FIG. 11 is a perspective view of the battery support frame retainer 127 for easy understanding of the internal configuration of the chronograph mode of the chronograph timepiece movement 300 according to the second embodiment of the present invention. 12 is a cross-sectional view taken along the line DD of FIG. Note that the mechanism for switching from the normal time mode to the chronograph mode is the same as in the first embodiment, and is therefore omitted.
As shown in FIGS. 11 and 12, in the chronograph mode, in the inspection terminal operation hole 127d, the inspection terminal 28a and the bulging portion 122b of the start / stop transmission lever 122 overlap in plan view.
(In actuality, the inspection terminal 28a is not visible, but is shown by a solid line for easy understanding.)
Accordingly, it is impossible to operate the inspection terminal 28a through the inspection terminal operation hole 127d, and it is impossible to confirm the operation of the time hand movement in the timepiece movement state. Therefore, it is possible to prevent the inspection related to the normal time mode from being erroneously performed in the chronograph mode.

  9 and 11, in the normal time mode, the bulging portion 122b of the start / stop transmission lever 122 cannot be seen through the inspection terminal operation hole 127d, whereas in the chronograph mode, the start / stop is performed through the inspection terminal operation hole 127d. The bulging part 122b of the transmission lever 122 is clearly visible. Accordingly, the mode of the chronograph timepiece movement 300 can be recognized by visually recognizing the inside of the inspection terminal operation hole 127d.

In the above, the inspection terminal 28a is a terminal for inspecting the inspection related to the normal time mode.
A system reset terminal of an IC (not shown) mounted on the circuit board 28 may be used.

  As a result, the system reset is always performed in the normal time mode. Therefore, as in the first embodiment, it is possible to more reliably perform the styling operation in the production process or AS.

[Third Embodiment]
Subsequently, a third embodiment of the present invention will be described. 3rd Embodiment is an Example which made removal of a battery impossible in a predetermined mode using this invention. In addition, the same number is attached | subjected about the component same as an already-described component, and description is abbreviate | omitted.
FIG. 13 is a perspective view of the battery support frame holder 27 in order to facilitate understanding of the internal configuration of the timepiece movement with chronograph 400 in the normal time mode according to the third embodiment of the present invention. 31 is a battery, 29 is a battery holder for fixing the chronograph timepiece movement 400 by holding the battery 31, 29a is a screwed portion of the battery holder 29, 30 is a screwed portion 29a of the chronograph timepiece movement. A battery holding screw for fixing to 400, 22 is a switching lever, and 22 b is a tip of the switching lever 22. These are modified and added as compared with the first embodiment. 14 is a cross-sectional view taken along line EE in FIG.

  As shown in FIGS. 13 and 14, in the normal time mode, the tip end portion 119a of the switching lever 119 and the screwing portion 29a of the battery retainer 29 do not overlap in plan view. Therefore, the battery 31 is held by the battery retainer 29 and the battery retainer screw 30.

  FIG. 15 is a perspective view of the battery support frame holder 27 in order to make it easy to understand the internal configuration of the chronograph mode of the chronograph timepiece movement 400 according to the third embodiment of the present invention. 16 is a cross-sectional view taken along line FF in FIG. Note that the mechanism for switching from the normal time mode to the chronograph mode is the same as in the first embodiment, and is therefore omitted.

As shown in FIGS. 15 and 16, in the chronograph mode, the front end portion 119 a of the switching lever 119 and the screwing portion 29 a of the battery retainer 29 overlap in a plan view. Therefore, the battery (not shown) is held by the battery retainer 29, the battery retainer screw 30, and the tip end portion 119a of the switching lever 119.
As described above, in the chronograph mode, as compared with the normal time mode, the battery 31 is firmly held by the tip portion 119a of the switching lever 119, and it is easy to prevent the battery from being detached. For example, even if the watch user gives a strong impact to the watch due to dropping or the like during time measurement with the chronograph, it is easy to prevent the battery from being detached, and time measurement can be continued.

  In addition, the battery 31 cannot be replaced in the chronograph mode. For this reason, since the battery 31 can be replaced only in the normal time mode in the production process or AS, the worker always works in the normal time mode. As a result, as in the first embodiment, it is possible to prevent the styling operation from being performed in the chronograph mode.

  As can be seen from FIGS. 13 and 15, the tip 119a of the switching lever 119 is not visible in the screwing portion 29a of the battery retainer 29 in the normal time mode, whereas the screwing portion of the battery retainer 29 is not visible in the chronograph mode. The tip end portion 119a of the switching lever 119 is clearly visible at 29a. Therefore, the mode of the chronograph timepiece movement 400 can be recognized by visually recognizing the screwing portion 29 a of the battery retainer 29.

[Fourth Embodiment]
In the first embodiment, the second embodiment, and the third embodiment, “using a component that operates at the time of mode switching, the component C is hidden in the mode A, and the component C is not hidden in the mode B”. However, there is also a mechanism that “uses a part that operates at the time of mode switching and fixes part C when in mode A, and does not fix part C when in mode B”. Such an embodiment is also conceivable.
FIG. 17 is a perspective view of the battery support frame holder 27 in order to make it easy to understand the internal configuration of the chronograph timepiece movement 500 according to the fourth embodiment of the present invention in the normal time mode and the winding stem 0 step pulled state. is there. In addition, the same number is attached | subjected about the component same as an already-described component, and description is abbreviate | omitted. 115 is a setting lever, 115 a is a recess provided in the setting lever 115 to improve operability when removing the winding stem, 115 b is a rib provided in the setting lever 115, and 115 c is a setting shaft shaft serving as a rotation axis of the setting lever 115. The setting shaft hole 115c is engaged with a setting shaft (not shown) fixed to the main plate. These are modified and added as compared with the first embodiment. 18 is a cross-sectional view taken along line GG in FIG.
As shown in FIGS. 17 and 18, in the normal time mode, the recess 115a and the tip 22a of the start / stop transmission lever 22 do not overlap in the setting operation hole 27a in plan view. Accordingly, the setting lever 115 can be operated through the setting operation hole 27a, and the winding stem 14 can be removed.

Next, the mechanism for switching from the winding stem 0-step pulling state to the winding stem 2-step pulling state will be described below with reference to FIGS. FIG. 19 is a perspective view of the battery support frame holder 27 in order to make it easy to understand the internal configuration of the chronograph timepiece movement 500 according to the fourth embodiment of the present invention in the normal time mode and the winding stem two-step pulled state. is there.
In FIG. 17, when the winding stem 14 is pulled from the timepiece movement, the state is switched from the 0-step pull state to the 1-step pull state and the 2-step pull state. At this time, the setting lever 115 engaged with the winding stem 14 rotates counterclockwise with the setting shaft shaft hole 115c as a rotation axis. Therefore, while pulling the winding stem 14, the portion of the setting lever 115 on the right side of the setting shaft shaft 115c moves upward, and the portion on the left of the setting shaft shaft hole 115c moves downward.

  17, 18, and 19, in the normal time mode, regardless of the state of the winding stem 14, the start / stop transmission lever 22 is in a position not in contact with the rib 115 b provided on the setting lever 115. Can be switched from the 0-step drawing state to the 1-step drawing state and the 2-step drawing state.

FIG. 20 is a perspective view of the battery support frame holder 27 in order to make it easy to understand the internal configuration of the chronograph timepiece movement 500 with the chronograph mode and the winding stem 0 step state according to the fourth embodiment of the present invention. is there. 21 is a cross-sectional view taken along line HH in FIG.
As shown in FIGS. 20 and 21, in the chronograph mode, in the setting operation hole 27a, the recess 115a and the tip 22a of the start / stop transmission lever 22 overlap in a plan view. Accordingly, the setting lever 115 cannot be operated through the setting operation hole 27a, and the winding stem 14 cannot be removed. Accordingly, it is possible to prevent the winding stem 14 from being erroneously removed in the chronograph mode.

In the chronograph mode of FIG. 20, the tip 22a of the start / stop transmission lever 22 and the rib 115b provided on the setting lever 115 are positioned adjacent to each other. In this state, when the winding stem 14 is pulled from the timepiece movement to change from the 0-step pulling state to the 1-step pulling state or the 2-step pulling state, the leading end 22a of the start / stop transmission lever 22 is provided on the setting lever 115. In order to lock the counterclockwise rotation of 115b, it is impossible to switch between the one-step pulling state and the two-step pulling state. Accordingly, it is possible to prevent the winding stem 14 from being erroneously switched between the one-stage drawing state and the two-stage drawing state in the chronograph mode.
As can be seen from FIGS. 17 and 20, in the normal time mode, the tip 22a of the start / stop transmission lever 22 cannot be seen through the setting operation hole 27a, whereas in the chronograph mode, the start / stop transmission lever 22 is shown through the setting operation hole 27a. Is clearly visible. Therefore, the mode of the chronograph timepiece movement 500 can be recognized by visually recognizing the inside of the setting operation hole 27a.

In the fourth embodiment of the present invention, in addition to the effects of the first embodiment, in the chronograph mode, it is impossible to switch the winding stem from the 0-step pull state to the 1-step pull state and the 2-step pull state. There is an effect to. As a result, it is possible to provide a watch that can prevent handing in a mode that is structurally wrong and that can be handed only in the correct mode, thereby improving productivity and preventing problems in the AS. Is possible.

In the above description, the first mode in which the operated part such as a blackbird can be operated is the normal time mode, and the second mode incapable of operation is the chronograph mode. However, the present invention is not limited to this. If there are operating parts corresponding to the levers in the above-described chrono mode, the second mode may be set to other function modes such as a timer mode, a local time mode, and an alarm time setting mode.
In addition, for example, in the case of an inspection terminal dedicated to the chronograph mode where it is difficult to operate the operated part in the normal time mode, the normal time mode may be set as the second mode.
In addition, modifications can be made without departing from the gist of the present invention.
