Description

  The present invention relates to a timepiece button lock mechanism, a timepiece movement having the mechanism, and a timepiece having the movement.

  In this specification, “locking” a button means that (at least one) operation of the button is restricted or prohibited.

  In a wristwatch in which a button provided on the side wall of the case is operated to perform calendar correction and other operations, it is desired to avoid malfunction caused by the push button being pushed by mistake. For this purpose, the force required to press the button (pushing weight) is increased, the protrusion length of the button head protruding relative to the surroundings is minimized, or the non-protruding state is practically set However, these means are not always desirable since it is difficult to press the buttons themselves even when necessary.

  On the other hand, various proposals have been made to incorporate a mechanism that locks the button in the head portion of the button (regulates or prohibits pushing of the button body) (for example, Patent Documents 1 to 4).

  However, in the case of the mechanism proposed in Patent Documents 1 to 4 and the like, since the lock mechanism is provided in the head of the button, it is difficult to avoid an increase in the head of the button.

  In addition, it has also been proposed to provide a movable cover or lid between the position where the button is covered and the position where the button is exposed outside the button provided on the side wall of the case (Patent Document 5).

  However, in this proposed mechanism, since the movable wall is provided on the side wall of the case, it is difficult to avoid the case itself from becoming large.

  Moreover, since the lock mechanisms of these Patent Documents 1 to 5 are all provided with a lock mechanism in the case or exterior part of the watch, the watch body or the movement itself still lacks the lock function and is the same. Even when a movement is used, it is necessary to provide a lock mechanism separately if the exterior is different.

  The present invention has been made in view of the above-described points, and an object of the present invention is to provide a timepiece button lock mechanism capable of reliably locking a button by the movement itself, a timepiece movement having the mechanism, and It is to provide a timepiece having the movement.

  In order to achieve the above object, the button lock mechanism of the present invention has a setting lever that can be swung between a setting position and a setting release position in accordance with the insertion / removal of the winding stem, and the movement of the setting lever. The first button lock lever that is set to the lock position when the setting lever is set to the set position and is set to the lock release position when the setting lever is set to the setting release position. If the setting lever is set to the set position according to the insertion / removal of the winding stem, the first button lock lever is set to the lock position to prevent the displacement of the first button, and the setting lever is set to the setting release position. When set, the first button lock lever is set to the unlocked position to allow the displacement of the first button.

  In the button lock mechanism of the timepiece according to the present invention, “when the setting lever is set to the set position in accordance with the insertion / removal of the winding stem, the first button lock lever is set to the lock position to prevent the displacement of the first button. When the setting lever is set to the setting release position, the first button lock lever is set to the lock release position and allows the first button to be displaced. Because it is arranged separately from the button, it is not necessary to enlarge the first button itself that is locked or unlocked, and the operation of the setting lever and the first button lock lever is controlled by inserting and removing the winding stem Therefore, the button can be locked and unlocked easily and reliably. Since the setting lever and the first button lock lever can be incorporated in the movement of the timepiece, the button lock mechanism of the timepiece of the present invention can be realized by the movement of the timepiece itself.

  In the button lock mechanism of the timepiece according to the present invention, the first button pushes a lever for calendar correction such as day correction to rotate the lever, and the first button lock lever is typically the calendar. Prohibit or allow the correction lever to rotate. That is, in the button lock mechanism of the timepiece of the present invention, typically, the first button lock lever directly performs the pressing operation of the first button by prohibiting the rotation of the calendar correcting lever. Restrict or ban indirectly. However, if desired, the first button lock lever may directly regulate or prohibit the pressing operation of the first button.

  In the button lock mechanism of the timepiece of the present invention, typically, when the setting lever is set to the set position in the normal use state or the normal use position at the normal position (0th stage position) where the winding stem is pushed in. When the first button lock lever is set to the locked position to prohibit the displacement of the first button (locking the first button) and the winding stem is pulled out, the setting lever is set to the setting release position The first button lock lever is set to the unlock position to allow the first button to be displaced (the first button is unlocked).

  In the button lock mechanism of the timepiece of the present invention, typically, the setting lever is composed of a setting lever that is rotated in accordance with the insertion and removal of the winding stem.

  In that case, the rotating operation of the setting lever that enables time correction or hand rotation at the winding stem pull-out position can be used as it is for controlling the swing operation of the first button lock lever. However, a separate setting lever may be engaged with the winding stem separately from the setting lever so as to swing in accordance with the insertion and removal of the winding stem.

  In the button lock mechanism of the timepiece of the present invention, typically, the setting lever includes an engagement pin, and the first button lock lever includes a non-linear elongated hole in which the engagement pin of the setting lever is engaged. And a locking portion that is located in the displacement path of the first button when set to the lock position and located outside the displacement path of the first button when set to the unlocked position.

  In that case, the first button lock lever is swung so that the engaging pin of the setting lever is swung according to the swing of the setting lever, and the pin can move along the elongated hole according to the swing, The locking portion of the first button lock lever is moved from the lock position to the lock release position, for example, to release the lock of the first button.

  In the button lock mechanism of the timepiece of the present invention, typically, the swing of the first button lock lever is the rotation about the rotation center axis, and the rotation center axis of the first button lock lever is , Located on the extension line of the displacement path of the first button.

  In this case, the first button can be reliably locked and unlocked by the first button lock lever. However, as long as the swing of the corresponding correction lever can be reliably regulated (prohibited) and allowed, it may be displaced in another direction at another position. That is, when this button lock mechanism restricts the rotation of a first (calendar) correction lever, which will be described later, the part that is pushed by the first button and the first button lock lever of the first correction lever. If the part to be moved (part supported from the back) is far away, the rocking of the correction lever is reliably regulated by selecting the position and orientation according to the rocking or rotating direction of the two parts (Prohibited) and allowed.

  As described above, the “swing” of the setting lever and the first button lock lever is typically a rotation around the respective rotation center axis as described above. If so, the rotation may not be uniaxial. In the case of rotation, when the first button is a push button, the rotation center of the first button lock lever is actually positioned on an extension line in the pushing direction of the first button. However, it may be separated to some extent if desired.

  In the button lock mechanism of the timepiece of the present invention, for example, it can be swung according to the swing of the first button lock lever, and when the first button lock lever is set to the lock position, the second lever lock position is set. When the first button lock lever is set and the lock release position is set, it further has a second button lock lever that is set to the second lever lock release position. When set to the position, the first button lock lever is set to the lock position, so that the second button lock lever is set to the second lever lock position to prevent the second button from being displaced. When the setting lever is set to the setting release position according to insertion and removal, the first button lock lever is set to the lock release position, so that the second button lock lever is set to the second lever. Configured to set the click release position to permit displacement of the second button.

  In that case, the winding and unloading of the winding stem can not only control the locking and unlocking of the first button from the setting lever via the first button lock lever, but also via the first button lock lever from the setting lever. The second button lock lever can be swung to control the lock and unlock of the second button via the second button lock lever. Here, the setting lever is shared. However, if desired, two sets of setting levers and button lock levers can be prepared, and the corresponding button lock levers can be swung from the winding stem via the respective setting levers. The respective buttons to be locked or unlocked may be performed.

  In this case as well, as in the case of the rotation center of the first button lock lever described above, typically, the second button lock lever swings around the rotation center axis. The rotation center axis of the second button lock lever is located on the extension line of the displacement path of the second button.

  In order to achieve the above object, the timepiece movement of the present invention has the button lock mechanism as described above and the first button lock lever that is set when the first button is pressed when the lock release position is set. A first correction lever that is swung by the first button according to the displacement of the first button; and a first calendar correction wheel that is swung according to the swing of the first correction lever. .

  In that case, turn the first calendar correction wheel through the first correction lever by putting the winding stem in and out, setting the first button lock lever to the unlocked position and operating the first button. The first calendar correction can be performed. Also, simply pull out the winding stem (typically push it to the normal position) and set the first button lock lever to the lock position to lock the operation of the first button (prohibit) Thus, the rotation of the first calendar correction wheel via the first correction lever can be prohibited, and the first calendar correction can be prohibited from being erroneously performed.

  Here, “calendar correction” typically refers to “day correction”, “day correction”, etc. (for example, “month correction”, etc.) as usual, but in this specification, In a broader sense, for example, “time difference correction” for displaying a time with a time difference is included.

  In the timepiece movement of the present invention, typically, when the second button lock lever is set to the second lever lock release position, the second button lock lever responds to the displacement of the second button accompanying the pressing of the second button. A second correction lever that is swung by the second button, and a second calendar correction wheel that is rotated according to the swing of the second correction lever.

  In that case, the first button can be locked or unlocked by the first button lock lever and the second button can be locked or unlocked by the second button lock lever at the same time when the winding stem is inserted or removed. .

  Here, the first calendar correction by the operation of the first button and the second calendar correction by the operation of the second button are typically processing for different calendar items, for example, the first calendar. If the correction is a day correction, the second calendar correction consists of a day correction. However, if desired, the second calendar correction may be of a completely different type from the first calendar correction, such as a time difference correction. Conversely, the first calendar correction is to advance the day of the week, the second calendar correction is to return the day of the week, etc., so that different (reverse) operations are performed for the same type of calendar correction. Also good.

  In the watch movement of the present invention, typically, the setting lever is set to the setting position when the winding stem is not pulled out and is in the normal position, and the setting lever is set when the winding stem is pulled out by one step. When the winding stem is set to the release position and the winding stem is pulled out by two stages, the setting lever is maintained at the setting release position and the calendar is corrected according to the rotation of the winding stem.

  In that case, it is possible to properly use an operation suitable for being performed by pressing a button or the like and an operation suitable for being performed by rotating the winding stem while changing the drawing position of the winding stem.

  In order to achieve the object, the timepiece of the present invention includes the button lock mechanism as described above or the timepiece movement as described above.

  The button lock mechanism 1 includes, for example, a setting lever mechanism 60 and a button lock lever 70 as shown in FIG.

  The setting lever mechanism 60 includes a yoke 67 in addition to a setting lever 61 and a yoke holder 64 as a setting lever. The setting lever mechanism 60 has a “set-up and swivel presser” of a conventional timepiece except that the set-up 61 has a tail pin (engagement pin) 61f to be engaged with the button lock lever 70 as described below. It can be configured in the same manner as “and kanuki”.

  A pinion wheel 14 or the like is fitted to the winding stem 12 having the small-diameter portion 12c so as to be capable of relative displacement in the E1 and E2 directions along the extending direction E of the winding stem 12. A crown 9 is attached to the outer end 12a of the winding stem 12 protruding outside the watch case, and the winding stem 12 can be taken in and out in the directions E1 and E2 with the crown 9.

  The setting lever 61 is rotatable around a rotation center shaft 61a, is engaged with the small diameter portion 12c of the winding stem 12 at the protruding head portion 61b of the setting shape portion, and the pins 61d and 61d of the leg portions of the setting shape portion. Are engaged with the recesses 64c and 64c of the yoke holder 64, and are engaged with the elongated hole 75 of the button lock lever 70 at the tail pin 61f of the setting lever. The setting lever 61 is further engaged with the recess 67d of the yoke 67 at the protruding portion 61g of the rear leg portion of the setting shape portion.

  Accordingly, when the winding stem 12 is pulled out in the E1 direction from the normal position P0 where the winding stem 12 is pushed in the E2 direction to the maximum, the setting lever 61 is rotated around the rotation center shaft 61a in the G1 direction according to the amount of the winding stem 12 pulled out in the E1 direction. In response to the rotation of the setting lever 61 in the G1 direction, the pins 61d and 61f and the protrusion 61g of the setting lever 61 are rotated in the G1 direction.

  The yoke holder 64 is loosely fitted to the rotating shaft portion 61a of the setting lever 61 at the concave portion 64b at the tip of one of the two arms, and is attached to the inner edge of the other arm portion in the form of an elastic arm portion of the two arms. The two recesses 64c and 64c of the formed recesses 64c are engaged with the pins 61d and 61d of the leg portion of the setting lever 61 that is in a desired rotation state to support the setting lever 61.

  The yoke 67 is in the form of a lever 67a and can be rotated in the H1 and H2 directions around the rotation center shaft 67b at the base end portion of the lever 67a. The yoke 67 includes an engagement end portion 67c engaged with the central small-diameter portion 14a of the wheel 14 at the distal end portion of the lever 67a, and an engagement recess portion including a plurality of small recess portions 67e on one side of the intermediate portion of the lever 67a. 67d. The yoke 67 further includes a yoke spring 67g integrally extending from the base end portion of the lever 67a, and receives an H1 direction biasing force by the spring 67g.

  In the setting lever mechanism 60 configured as described above, when the winding stem 12 is in the normal position pushed in the E2 direction, that is, in the 0th stage P0, the setting position of the setting lever 61 rotated to the maximum in the G2 direction (FIG. 3). (Position indicated by solid line) PS0, and the pins 61d and 61d of the setting lever 61 are fitted into the left end portions 64c and 64c of the plurality of recesses 64c of the yoke holder 64.

  At this time, the protruding portion 61g of the setting lever 61 is fitted into the small recess portion 67e on the left end side of the recess 67d of the yoke 67 that is spring-loaded by the spring 67g, and the engagement end 67c at the tip of the yoke 67 is H1. The pinion wheel 14 is displaced in the direction, and the pinion wheel 14 is displaced relative to the winding stem 12 to the maximum in the E1 direction.

  Therefore, when the timepiece 3 is a mechanical timepiece, when the winding stem 12 is rotated in the J1 direction around the central axis J, the rotation of the winding stem 12 is rotated from the jamming wheel 14 and the chime wheel 15 to the mainspring winding wheel. Winding of the mainspring is performed by transmission through a row (not shown).

  On the other hand, when the winding stem 12 is pulled in the E1 direction and is set to the first stage position P1 that is pulled out by one stage (for example, FIG. 6 described later), the setting lever 61 is rotated in the G1 direction, which is one point in FIG. The winding stem first stage position PS1 indicated by a chain line 61i1 is taken, and the pins 61d and 61d of the setting lever 61 are fitted into the intermediate concave portions 64c and 64c of the concave portion 64c of the yoke holder 64. At this time, the protrusion 61g of the setting lever 61 engages with the intermediate small convex portion 67f of the concave portion 67d of the yoke 67, and the engaging end portion 67c at the tip of the yoke 67 is rotated in the H2 direction. The handwheel 14 is displaced relative to the winding stem 12 in the E2 direction.

  In that case, when it is a type of timepiece in which the dial 15 has a date window and the date is displayed, if desired, the winding stem 12 and the date correction wheel train (not shown) are engaged, It is also possible to change the date display by the date wheel by turning the winding stem 12 to turn the date correction wheel train.

  When the winding stem 12 is further pulled in the E1 direction and set to the second stage position P2, the setting lever 61 takes the winding stem second stage position PS2 indicated by a two-dot chain line 61i2 in FIG. The pins 61d and 61d fit into the concave portions 64c and 64c at the right end of the concave portion 64c of the yoke holder 64. At this time, the protruding portion 61g of the setting lever 61 is fitted into the small concave portion 67e on the right end (front end) side of the concave portion 67d of the yoke 67, and the engagement end portion 67c at the front end of the yoke 67 is further rotated in the H2 direction. Thus, the clutch wheel 14 is further displaced relative to the winding stem 12 in the E2 direction.

  Therefore, if desired, the pinion wheel 14 is engaged with a minute wheel (not shown) via an intermediate wheel (not shown) such as a small iron wheel, and the winding wheel 12 is turned to turn the minute wheel. It is also possible to adjust the hour / minute hands via the hand.

  The button lock lever 70 of the button lock mechanism 1 includes a lock lever main body portion 71, a lever positioning input portion 72 formed on the enlarged portion 71a located at the front end of the main body portion 71, and a distal end of the lever main body portion 71. It has a button push-in restricting portion 73 formed at the extended end portion extended through the extended portion 71b, and can rotate in the K1 and K2 directions around the rotation center shaft 74 at the base end portion. Are supported by the second base plate 22.

  The lever positioning input portion 72 of the enlarged portion 71a is formed with a generally “L” -shaped long hole 75 into which the engaging pin 61f of the setting lever 61 is loosely fitted. The long hole 75 includes hole portions 75a and 75b connected so as to form an “L” shape as a whole. The angle between the holes 75a and 75b is typically an obtuse angle. When the setting lever 61 takes the winding true zero (0) step position PS0, the engaging pin 61f of the setting lever 61 is loosely fitted to the tip 75c of the hole 75a in the elongated hole 75, and the winding stem 12 is When the setting lever 61 is pulled in the E1 direction and takes the first step position P1 and the setting lever 61 takes the winding stem first step position PS1, the engagement pin 61f of the setting lever 61 is bent in the holes 75a and 75b of the elongated hole 75. The state in which the winding stem 12 is loosely fitted to the connecting portion 75d is taken, the winding stem 12 is further pulled out in the E1 direction to take the second step position P2, and the setting lever 61 takes the winding stem second step position PS2. The combination pin 61f is configured to be loosely fitted into the end 75e of the hole 75b in the long hole 75.

  As shown in FIG. 1 in addition to FIG. 3, the button push-in restricting portion 73 located at the extended end portion is provided with a support portion 76 that extends greatly with respect to the lock lever main body portion 71 and the extended portion 71 b, and And a force receiving portion 77 formed by bending the tip of the support portion 76 substantially at a right angle. The force receiving portion 77 of the button push-in restricting portion 73 is practically similar to the rotation center shaft 74 when the winding stem 12 is at the zero stage position P0 and the setting lever 61 is at the winding stem zero stage position PS0. The push button 11 is located on the extension of the push direction line (virtual line) B.

  As will be described in detail below, when the winding stem 12 is at the 0-th position P0, the force receiving portion 77 of the support portion 76 of the button push-in restricting portion 73 located at the tip of the button lock lever 70 is Located behind the pressing force receiving portion 58, the pressing of the push button 11 in the B1 direction is restricted or prohibited. When the winding stem 12 is pulled out in the E1 direction, the pressing of the push button 11 in the B1 direction is permitted.

  In the timepiece 3 configured as described above, when the winding stem 12 is in the 0th position P0 pushed in the E2 direction as shown in FIG. 5, the setting stem 61 is rotated in the G2 direction. Taking the eye position PS0, the engaging pin 61f of the setting lever 61 is positioned at the end 75c of the elongated hole 75 of the button lock lever 70, and the button lock lever 70 is rotated in the K2 direction. The force receiving portion 77 of the support portion 76 of the button pressing restricting portion 73 adopts the button pressing prohibiting position Q0 as a locking position located just behind the pressing force receiving portion 58 of the day correcting lever 51, and A1 of the day correcting lever 51 Restrict or prohibit direction rotation. Therefore, even if the pressing force in the B1 direction is accidentally applied to the push button 11 in the winding stem 0 stage P0, the displacement of the push button 11 in the B1 direction is rotated by the force receiving portion 77 of the button lock lever 70 in the A1 direction. Since the pressing force receiving portion 58 of the day correction lever 51 whose movement is prohibited is restricted or prohibited, it is possible to avoid erroneous operation of the push button 11.

  On the other hand, in the timepiece 3, when the winding stem 12 is pulled in the E1 direction from the 0th step position P0 shown in FIG. 5 to the 1st step position P1 shown in FIG. 6, the setting lever 61 of the setting lever mechanism 60 is pivoted. It is rotated around the shaft 61a in the G1 direction. With this rotation in the G1 direction, the engaging pin 61f of the setting lever 61 loosely fitted in the elongated hole 75 of the button lock lever 70 moves from the end portion 75c to the connecting portion 75d in the elongated hole 75, With the movement of the pin 61f, the button lock lever 70 is rotated in the K1 direction from the button press-prohibited position Q0 as the lock position in FIG. 5 to the button press-allowed position Q1 as the lock release position in FIG. When the button lock lever 70 reaches the button push allowable position Q1 as the lock position, as can be seen from FIG. 6, the force receiving portion 77 of the support portion 76 at the tip of the button lock lever 70 is the displacement path B of the push button 11 or its Deviate from the extension line.

  Therefore, when the push button 11 is pushed in the B1 direction, the tip of the push button 11 hits the pushing force receiving portion 58 of the day correcting lever 51 and pushes the pushing force receiving portion 58 in the B1 direction, so that the day correcting lever 51 is A1. Rotate in the direction and push the engagement tooth 46a of the day star wheel 46 with the day correction claw portion 57 at the tip to rotate the day wheel 45 in the D1 direction to advance the day of the week by one day. In order to further advance the day of the week, it is only necessary to once again release the B1 direction pressing of the push button 11 and then repeat the B1 direction pressing again.

  That is, in this example, the button lock lever 70 is pushed from the button push-in prohibition position Q0 through the setting lever mechanism 60 by setting the winding stem 12 to the first position P1 of the winding stem pulled out in the E1 direction. It is displaced to the allowable position Q1, and the push button 11 is pressed. In other words, at the winding stem 0 stage position P0 (FIG. 5) in which the winding stem 12 is pushed in the E2 direction, the setting lever mechanism 60 engaged with the winding stem 12 pushes the button lock lever 70 into the button pushing prohibiting position Q0. Therefore, pushing the push button 11 in the B1 direction is prohibited. At this time, the gap between the tip of the push button 11 and the pressing force receiving portion 58 of the day correction lever 51 can be minimized, so that the push stroke of the push button when the operation of the push button 11 is effective is minimized. Can be suppressed.

  In this example, the button lock lever 70 is configured such that the force receiving portion 77 of the support portion 76 supports the pressing force receiving portion 58 of the day correcting lever 51 from behind, thereby preventing the push button 11 from being pressed in the B1 direction. However, in the button lock lever 70, the force receiving portion 77 of the support portion 76 is in direct contact with the front end portion of the push button 11 on the front surface of the pressing force receiving portion 58 of the day correction lever 51, and the push button 11 is pressed in the B1 direction. May be prohibited.

  As described above, in the timepiece 1, when the winding stem 12 is at the normal position (0th position) P0, the setting lever mechanism 60 set to the winding stem 0th position PS0 by the winding stem 12 is set. By setting the button lock lever 70 to the button push-in restricting (prohibited) position Q0 via the loose fitting engagement between the engaging pin 61f and the elongated hole 75 of the button lock lever 70, the setting lever 61 as a lever B1 direction displacement of the pressing force receiving portion 58 of the day correction lever 51 of the correction mechanism 50 is prohibited, and the rotation of the day correction lever 51 in the A1 direction is restricted, whereby the day correction claw portion 57 of the day correction lever 51 is used. Since the D1 direction rotation drive of the day star wheel 46 is prohibited, there is no possibility that the day display is erroneously changed even if there is an unexpected B1 direction press on the push button 11. That is, in the timepiece 3, the movement 2 itself of the timepiece 3 includes the button lock mechanism 1 including the winding stem 12, the setting lever mechanism 60 setting lever 61, and the button lock lever 70. The operation of the push button can be regulated by the movement 2 itself of the timepiece 3 without depending on the structure of the exterior parts. Therefore, it is possible to avoid the possibility that the button 11 is actuated (pressed) without the user's knowledge while the watch 3 is being worn on the wrist.

  In other words, in this timepiece 3, when the winding stem 12 is in the first step position P1 pulled out by one step in the E1 direction, the setting lever set to the winding stem first step position PS1 by the winding stem 12 The setting lever 61 as the setting lever of the mechanism 60 sets the button lock lever 70 to the button pushing allowable position Q1 through the loose engagement between the engagement pin 61f and the elongated hole 75 of the button lock lever 70. The B1 direction displacement of the pressing force receiving portion 58 of the day correction lever 51 of the day correction mechanism 50 is allowed, and the A1 direction rotation of the day correction lever 51 is allowed, whereby the day correction claw portion 57 of the day correction lever 51 is allowed. Therefore, the day correction lever 51 is rotated in the A1 direction in response to the push of the B1 direction against the push button 11, and the day correction claw portion 57 passes the day star wheel 46 via the day star wheel 46. By rotating the day indicator 45 in the D1 direction, day corrector is performed. That is, in the timepiece 3, the movement 2 itself of the timepiece 3 includes the button lock mechanism 1 including the winding stem 12, the setting lever mechanism 60 setting lever 61, and the button lock lever 70. The movement 2 itself of the timepiece 3 can correct the day of the week while avoiding an erroneous operation of the push button without depending on the structure of the exterior parts.

  Here, the push button 11 and the lever 51 that the button lock lever 70 restricts (allows) or allows the pressure to be pressed are not corrected for the day when pressed or rotated, but instead of the day correction or the time difference. Modifications, other modifications, and other operations may be performed.

  Further, in accordance with the insertion and removal of the winding stem 12, instead of restricting (prohibiting) or allowing the pressing of one push button, the pressing of a plurality of push buttons may be regulated (prohibited) or allowed. Good.

  Next, a timepiece 3A having a movement 2A provided with a button lock mechanism 1A configured such that the pressing of two push buttons is restricted (prohibited) or allowed depending on the insertion and removal of the winding stem 12 will be described with reference to FIGS. 8 will be described.

  In this button lock mechanism 1A, the setting lever 61A as a setting lever of the setting lever mechanism 60A can rotate around the rotation center shaft 61aA, and the small diameter portion 12cA of the winding stem 12A at the protruding head 61bA of the setting shape portion. Is engaged with the elongated hole 75A of the button lock lever 70A at the pin 61fA of the tail portion of the setting part.

  As with the setting lever 61 shown in FIG. 3 and the like, the setting lever 61A can be engaged with a recess of a yoke (not shown) at the protruding portion 61gA of the rear leg portion of the setting lever portion, for example. However, as long as the setting lever 61 </ b> A can control the button lock mechanism 1 </ b> A as a setting lever, the setting lever 61 </ b> A may not be engaged with the yoke or the like.

  Also in this example, when the winding stem 12A is pulled out in the E1 direction from the normal position where the winding stem 12A is pushed in the maximum in the E2 direction, the setting lever 61A moves around the rotation center axis 61aA according to the amount of the winding stem 12A pulled out in the E1 direction. The pin 61fA and the protrusion 61gA of the setting lever 61A are rotated in the G1 direction according to the rotation of the setting lever 61A in the G1 direction.

  For example, the movement 2A of the timepiece 3A is similar to the movement 2 of the timepiece 3 shown in FIGS. 1 to 3 and FIGS. 4 to 5 in the B1 direction pressing force from the day correction button 11 by the pressing force receiving portion 58A. For example, a time difference correcting lever or a date correcting lever 50B that is operated by receiving a pressing force in the R1 direction from the time difference correcting button or the date correcting button 13 in the pressing force receiving portion 58B. Is provided. In this case, every time the date correction button 13 is pressed in the R1 direction, the date correction lever 50B is rotated in the T1 direction, and for example, date correction is performed in which the date display by the date indicator is advanced on a daily basis.

  Hereinafter, the timepiece 3A in which the day of the week is corrected by the push button 11 and the lever 50A and the day of the week is corrected by the push button 13 and the lever 50B will be described. As shown in FIG. 8, the timepiece 3 </ b> A has a date correction push button 13 and a date window 18 in the direction of about 4 o'clock as shown in FIG. 8. The position of the date window 18 may be different.

  As shown in FIG. 7A and the like, the button lock mechanism 1A is engaged with the first button lock lever 70A in addition to the first button lock lever 70A substantially similar to the button lock lever 70. Two button lock levers 90 are provided.

When the winding stem 12A is at the 0-th position P0, the force receiving portion 77A of the support portion 76A located on the distal end side of the main body portion 71A of the button lock lever 70A is positioned behind the pressing force receiving portion 58A of the day correction lever 51A. Then, the pressing of the push button 11A in the B1 direction is restricted or prohibited ((a) in FIG. 7), and when the winding stem 12A is pulled out in the E1 direction, it escapes from behind the pressing force receiving portion 58A and B1 of the push button 11A. The pressing in the direction is allowed ((b) and (c) in FIG. 7).

  The link arm portion 80 of the first button lock lever 70A extends from the rotation center shaft portion 74A to the extended end portion 81 at a substantially right angle to the main body portion 71A of the first button lock lever 70A. An engaging pin 82 is implanted in the extended end portion 81. The engaging pin 82 of the extended end portion 81 is generally located along the extending direction of the winding stem 12.

  In the button lock mechanism 1A, the setting lever 61A is rotated in the G1 direction around the rotation center axis 61aA in accordance with the pulling of the winding stem 12A in the E1 direction, and accordingly, the first button lock lever 70A and its related portion 77A. , 82 and the like are rotated in the K1 direction, and the setting lever 61A is rotated in the G2 direction around the rotation center axis 61aA in response to the pushing of the winding stem 12A in the E2 direction, and accordingly, the first button lock lever 70A is rotated. And the related parts 77A, 82, etc. rotate in the K2 direction. Here, when the winding stem 12A takes the 0-th position P0, the force receiving portion 77A of the first button lock lever 70A takes the button pushing restriction (prohibited) position Q0, and the winding stem 12A is pulled out 1 When the step position P1 or the second step position P2 is taken, the force receiving portion 77A of the first button lock lever 70A takes the button push allowable position Q1.

  In this button lock mechanism 1A, when the winding stem 12A takes the 0th position P0 and the force receiving portion 77A of the first button lock lever 70A takes the button push-in restriction (prohibited) position Q0, the link arm portion The engaging pin 82 of the 80 takes the button pushing restriction (prohibition) instruction position U0, and takes the first stage position P1 and the second stage position P2 from which the winding stem 12A is pulled out, and receives the force receiving portion of the first button lock lever 70A. When 77A takes the button push allowable position Q1, the engagement pin 82 of the link arm portion 80 takes the button push allowable instruction position U1.

  The second button lock lever 90 has substantially the same shape as the first button lock lever 70A except for the lever positioning input portion 72A and the enlarged portion 71aA, and is shown in FIGS. Seen in such a plan view, the center axis of the winding stem 12A is generally symmetric.

  More specifically, the second button lock lever 90 is generally similar in shape to the link arm portion 80 of the first button lock lever 70A and has an “L” shape as a whole with the link arm portion 91 on the input side. In the same manner as the main body 71A of the first button lock lever 70A, the output arm 92 extends at right angles to the link arm, and the pivot shaft 94 is connected to the connecting portion of the arms 91 and 92. Can be rotated in the directions of V1 and V2.

When the button push restriction (prohibition) instruction position U0 is taken, the force of the second button lock lever 90 engaged with the engagement pin 82 by the recess 95 of the engagement end portion 93 of the input side arm portion 91 is used. The receiving portion 97 adopts a button press restriction (prohibition) position W0 as a lock position.

  In this case, pushing in the B1 direction of the day correction button 11 at the 2 o'clock position is prohibited by the force receiving portion 77A of the first button lock lever 70A at the button pushing restricting (prohibited) position Q0, and at the 4 o'clock position. The day correction button 13 in the R1 direction is pushed by the force receiving portion 97 of the second button lock lever 90 at the button push restriction (prohibition) position W0. That is, on the one hand, rotation of the day correcting lever 51A in the A1 direction is prohibited by the force receiving portion 77A of the first button lock lever 70A at the button pushing restriction (prohibited) position Q0, and on the other hand, T1 of the day correcting lever 51B. Directional rotation is prohibited by the force receiving portion 97 of the second button lock lever 90 located at the button pressing restriction (prohibition) position W0. All of these restrictions or prohibitions are realized by the functions of the movement 2A itself of the timepiece 3A without depending on exterior parts such as the timepiece case 8.

  On the other hand, the winding stem 12A takes the first-stage position P1, the force receiving portion 77A of the first button lock lever 70A takes the button push allowable position Q1, and the engagement pin 82 of the link arm portion 80 pushes the button push allowable instruction position U1.

When the engaging pin 61fA of the setting lever 61A is bent along the hole 75bA in the elongated hole 75A and displaced from the connecting part 75dA to the end 74eA, the engaging pin 61fA is displaced along the extending direction of the hole 75bA. Therefore, the first button lock lever 70A is not rotationally displaced, and the second button lock lever 90 is not rotationally displaced. However, if desired, the elongated hole 75A may have a shape that causes rotational displacement within a range in which the button is allowed to be pressed.

  At the second position P2 where the winding stem 12A is shown in FIG. 7C, for example, as in the case of a normal analog timepiece (hand-type timepiece), the rotation of the winding stem is not shown and the date is not shown. It is transmitted to the wheel train (wheel train in the area indicated by the imaginary line in FIG. 7C) 20 through the back wheel including the hour wheel and the minute wheel. The indicated position is corrected).

  Even in the timepiece 3A having the movement 2A provided with the button lock mechanism 1A, the restriction (prohibition) and allowance of the pressing operation of the buttons 11 and 13 do not depend on the exterior parts such as the timepiece case, etc. It can be done by the mechanism itself. Further, in the timepiece 3A having the movement 2A provided with the button lock mechanism 1A, the operation of the two push buttons 11 and 13 can be controlled, so that more complicated control and control of the operation can be reliably performed.

  In the following, the clock 3A is described in which the day of the week is corrected by the push button 11 and the lever 51A and the date is corrected by the push button 13 and the lever 51B. However, the push button 13 and the lever 51B are corrected for the date. Instead of performing, other display modification or change, for example, time difference correction may be performed. In the case of time difference correction, each time the time difference correction button 13 is pressed in the R1 direction, the time difference correction lever 51B is rotated in the T1 direction, for example, a time difference for correcting the position of the hour hand and the minute hand in units of 30 minutes or 1 hour. Make corrections.

  In addition, for example, the push button 11 is a forward direction time difference correction or advance direction date correction button for advancing the time difference or date, and another push button 13 is a delay direction time difference correction or a delay direction date correction button for delaying the time difference or date. In that case, the push button 11 or 13 can be corrected in the direction to advance or delay the hand of the timepiece 1A according to the time difference or according to the time difference by pressing the B1 direction or the R1 direction of the push button 11 or 13. .
