Description

[Detailed description of the invention]

The present invention relates to an analog electromechanical watch with a calendar device, and more particularly to a device for setting the time and date displayed by an analog electronic M44 watch. The device for setting the time and date displayed by an electromechanical clock is a device consisting of a manual setting bullet with a square section along which a sliding pinion moves, and a setting device.・Has a lever,
One arm of this setting lever is received in an annular groove provided in the manual setting lever and also cooperates with a through slot shaped like the lever of the manual setting pinion; - the other arm cooperates with a retaining bridge and a reversing yoke so that the setting lever is held in one of three positions when the manual setting bar is withdrawn;
This reversing yoke has one arm received in the annular groove of the sliding pinion and another arm cooperating with the respective arm of the setting lever (
Serteina Kang/e-nee magazine No. 10 published in 1977
8.77.6 and figures 210.13-14 of the Ezeusse Société Anonyme magazine). This retaining bridge has two elastic members, one with three notches cut into its side to hold the setting lever in its respective position, and another elastic member with three notches cut into its side to hold the setting lever in its respective position. The member can move the manual set # by pressing axially on the pivot pin of the setting lever and retracting the arm of the setting lever from the annular groove of the manual set rod on the bridge side of the main plate of the watch. It has been made so that it can be unlocked. This is necessary when the watch device is assembled and installed inside the case. One of the lever arms of the manual set pinion is 19
A pin holder supports a single turnable manual setting pinion, and the other arm has a through-shaped slot for cooperating with a setting lever. The guide cam of the lever of the manual set binion provides time movement (permanent meshing) of the sliding binion and the manual set e-binion. When the manual set rod is in its neutral or idle position, the setting pinion is not engaged with the gear wheel. When the manual setting pin is pulled to its intermediate axial position, it engages the date stop wheel of the calendar; when pulled to its outermost position, the setting pinion engages the minute hand pinion. . The setting lever, reversing yoke, setting pinion lenoma and retaining bridge are mounted on the main plate of the watch from the front side. The above device has the following features. First, it is difficult to manufacture due to the complex moving parts of the device, requiring complex shapes of its components and high precision in its manufacture. Moreover, the kinematically complex situation in which the setting pinion is engaged alternately with the date correction wheel and the minute hand wheel impairs the reliability of the performance of the device and cannot reliably prevent the engagement wheel from sticking. So it will eventually result in tooth breakage. Second, there is a considerable amount of equipment components, the existence of screw connections, the fact that all the mounting parts mentioned above are sprayed, and the number of parts of other functional equipment (calendar, step motor, etc.). Proximity to the attachment points complicates assembly of the clock part and impedes work order process control of the assembly procedure. (See also the analog electromechanical clock 8 clock and the 8700 quartz wristwatch manufactured by the company). The manual setting rod has a square section and supports a double-limbed sliding pinion that is axially movable between three fixed positions. The movement of this pinion over the square section of the manual setting rod is effected by a setting lever and a reversing yoke. One of the arms of this setting lever has a stud pressed into it, which is adapted to enter the groove of the manual setting lever and rotate the setting lever when the rod is moved axially. The other arm of the lever also has another stud pressed in at the same time, which co-operates with the elastic retaining member of the retaining bridge. The end of this other arm of the setting lever has a 1K11 surface which permanently engages the shaped side of the reversing yoke, which side is in the form of the resilient arm of the retaining bridge. When the manual setting marker is pulled to the intermediate position, the reversing yoke axially moves the double-limbed sliding pinion to engage one of its toothed limbs with the date setting lever. At this position +t of the bar, a rapid correction of the date displayed by the calendar device takes place. When the manual setting rod is pulled out to its outermost position, the reversing yoke engages the other toothed rim of the sliding pinion with the setting pinion. If you turn the rod in this state, the hour and minute hands will move to show the exact time. The above-mentioned disadvantages of the previously mentioned devices are also present in this device. The closest prior art to the present invention is a time and date setting device displayed by an analog electromechanical clock incorporated in the Y468 quartz watch with step motor manufactured by Seiko Corporation of Japan. The device has a rotatable manual set rod that can be moved axially between three fixed positions. A double-limbed sliding pinion is mounted on the square section of this rod, which can move axially relative to this rod. The two toothed rims of this pinion are such that, when the pinion is moved axially, they alternately engage the setting pinion and the teeth of the gear wheel of the calendering device, respectively. When the first engagement is in progress, rotating the manual set rod moves the hour and minute hands, and the second
Once this engagement has taken place, the rotation of the coin will result in a rapid setting of 8 ladles as indicated by the calendar device. The axial movement of the double-limbed sliding pinion with respect to the fully manual setting lever is carried out by means of a device comprising: 1 a setting lever and a reversing yoke; This setting bone lever has one arm that is received in a groove provided for manual setting, and the other arm that is
It slides into a shaped slot provided on the side of the inversion yoke and acts as a guide cam. The setting lever is a pivot bolt mounted in a hole in the main plate of the watch, and its axial movement is positioned on the main plate by two studs and prevented by a leaf spring mounted with screws. There is. By pressing down on the pivot pin of the setting lever from the bridge side (S side), its arm is retracted from the annular groove of the manual setting rod, releasing it for removal. This is necessary when assembling the complete watch mechanical case or when removing it from the case. The inversion yoke is a -order lenomer. Three notches are provided on the side of the central part. A resilient member integral with the reversing yoke permanently presses the surface of the shaped slot into engagement with the side surface of the end of each arm of the setting lever. The inverted yoke end bent from the plane of the yoke is received by the annular groove of the double limb sliding pinion to move the pinion. When the manual set # is pulled out or pushed in, the notches in the profile slots on the sides of the reversing yoke provide three fixed positions rt for each part connected to those notches. The reversing yoke is integral with the main body of the main plate and is mounted on internally threaded pins which act as anchoring points for the setting lever springs. An additional bridge centered on the clock main plate by a single stud and secured by screws serves to limit the axial movement of the free arm of the reversing yoke and also to remove the manual setting rod. The setting lever, the reversing yoke, the leaf spring of the setting lever, and the additional bridge are It is mounted on the main plate of the watch from its front side. This last-mentioned construction is not free from any of the above-mentioned drawbacks. Moreover, the insufficient reliability of this device is due to the fact that: [It gets worse. Since the sliding pinion of the double rim and the setting pinion are engaged in a similar manner by cam action, the teeth of the wheels that engage each other are locked together during the engagement action. Possible damage when bumped on the way cannot be prevented.The fact that the manual setting rod is removed only from the bridge side makes its design a one-piece case watch design (case, pack). The object of the invention is to create a device for setting the time indicated by the hour and minute hands and the date indicated by the calendar of an electromechanical watch. The purpose of this is to provide a setting lever and a reversing yoke of a structure which facilitates the manufacture of the device and improves its assembly.

It can be mounted in a case without a back cover. Furthermore, the disclosed body of this device can prevent the teeth of the setting pinion from breaking, thus improving the reliability of the timepiece mechanism. The invention will be described in detail by way of example embodiments thereof with reference to the accompanying drawings, in which: FIG. In the drawings, the device for setting the time and date displayed by an analog 1 child mechanical watch has a manual setting ring 1 (Figs. 1 and 2), whose square cross section is oriented in the axial direction. It supports a double-limb sliding pinion 2 that can move freely. The toothed rim 2a of this pinion 2 is inserted into the date ring 3 (the first
100 pictures) will be co-operated with @. The other toothed rim 2b (Figs. 1 and 2) of the sliding pinion 2 is used for setting the hour and minute hand readings.
It is adapted to engage with the pinion 5. The main plate of the clock is set/? It has a stud 6 (FIG. 3) which passes freely through a -7 shaped slot, which in the case of the embodiment just described is a closed slot. In another embodiment (FIG. 4), the shaped slot of the setting lever 7 is open. Stud 6 (
3 and 4) has an enlarged head i6m and holds the setting lever 7 so that it does not move unnecessarily in the axial direction. In the embodiment shown in FIG. 3, the slots in the closed configuration of the setting lever 7 are three in number, each 7 m long. 7b and 7c, of which 7a and 7b have a curvature that corresponds to the diameter of the stud 6, while a third surface 7C has a curvature that corresponds to the diameter of the enlarged end head 6a of the stud 6. ing. In the embodiment illustrated in FIG.
The shape of the opening slot is defined by two faces 7& and 7b, the curvature of which corresponds to the diameter of the stud 6. One of the arms 7d (Figs. 1 and 3) of the setting lever 7 has a stud 8 pressed into it, which stud is received in the annular groove 1b of the manual setting rod 1. be done. In other embodiments, the setting and ? -7(M

be accepted by the public. In the embodiment now being described, the elastic arm 10s of the yoke 10 is in pressure contact with a pin 12 press-fitted into the main plate of the watch. The disclosed device for setting the time and date displayed by an analogue electromechanical watch operates as follows. In the idle fuse or normal position of the manual setting lever 1 (FIGS. 3 and 4), the pin 9 of the setting lever 7 is in the notch of the reversing yoke 1o. 10a,
The elastic arm 10e of the yoke 100 is pressed against the pin 12 and is pressed against the pin 9 of the setting lever 7, while at the same time the arm 10f of the yoke 10 is pressed against the pin 9 of the setting lever 7.
The rim sliding pinion 2 is held in its neutral position, and its toothed rims 2a and 2b are separated from the other parts. When the manual setting rod 1 is pulled out to its neutral position, its annular groove 1b moves the stud 8 of the setting L//7-7, so that the setting lever moves clockwise around the stud 60. The rotating pin 9 slides along the open loss slot (7) of the reversing yoke 1o, so that the reversing yoke can be rotated clockwise around the pin 110 by the action of the bent elastic arm lOe. Make it. When the yoke 1o rotates in this manner, it moves the two-rim sliding pinion 2 in the axial direction by its arm 10f, so that its toothed rim 2a'jz date ring 3 (FIG. 1)
Alternatively, it is engaged with the teeth of the date corrector 4 (Fig. 2). This rotation of the reversing yoke 10 (FIGS. 3 and 4) occurs when the pin 9 of the setting novice 7 is inserted into the notch 10b of the yoke 1o.
It is carried out until it enters. In this position, when the manual setting rod l is rotated, the date displayed by the calendar device is specifically corrected and then displayed by the clock. The time that is displayed remains unaffected. When the manual setting bale 1 is pulled out to its outermost position, the setting lever 7 rotates further clockwise and its pin 9 slides further along the shaped slot on the side of the reversing yoke IO. The yoke 101 - rotates counterclockwise around the pin 110 and further bends the elastic arm 10 , while the arm 10 f of the reversing yoke 10 moves the two-rim sliding pinion 2 - in the axial direction and bends its toothed rim. 2bt
The setting pinion 5 is engaged with the setting pinion 5. This rotation of the yoke lO is terminated by the pin 9 entering the notch 10c. In this position, by rotating the manual setting rod 1, the time indicated by the minute and hour hands is set. In this way, when the calendar date is set in the structure disclosed herein, the reversing yoke 10 rotates clockwise under the action of the bent elastic arm 10e, and engages the teeth of the toothed rim 2 of the pinion 2. , and the teeth of the date ring 3 (FIG. 1) or the date corrector 4 (FIG. 2), thereby preventing the teeth from being damaged. Breaking of the teeth is similarly prevented when the minute and hour hand readings are set. If anything, the toothed rim 2b of the sliding pinion 2 (Fig. 1,
The fact that the teeth of the pinion 5 (Fig. 2) and the teeth of the pinion 5 collide with each other when they engage is due to the open slot) 10 d (Figs. 3 and 4).
This is because the rotation of the yoke 10 is prevented by rotating the yoke 10 around the point where its end 10f engages with the end surface 2d of the annular groove 2c of the two-rim sliding pinion 2. The entire set of component parts of this device is mounted from the inside of the main plate using the following procedure. When the arm 10e (FIG. 5) is bent against the pin 12, the yoke 10 fits under the pin 11 and the enlarged end head of the pin. The large diameter surface 7c of the closed slot of the setting lever 7 coincides with the enlarged end head of the stud 6, so that the lever 7 can be freely placed on this stud 6. When the setting lever 7 is rotated counterclockwise at this stage, its pin 9 is removed from the reversing yoke 10. Next, when the setting lever 9-7 is rotated clockwise, the lever 9-7 is engaged with the notch 10m of the reversing yoke 10, and the setting lever 7 is moved by the action of the elastic arm 10e of the yoke 100. It can be moved until its surface 7a engages with the stud 6. When the lever 7 is now moved in the direction indicated by arrow B in FIG. 5 until the stud 6 enters the notch defined by the face 7b of the slot in the lever 7, the bin 8 (FIG. 1) is moved. , it is pulled out from the shaft of the manual setting camphor 1 by a distance exceeding half the diameter of the Zen 1. The two-rim sliding pinion 2 (FIG. 5) has its annular groove 2e (FIGS. 1 and 2) connected to the arm 10 of the reversing yoke 10.
After being positioned by placing it on the holder f (FIG. 5), the manual setting rod 1 is inserted (FIGS. 1 and 2). By resetting the lever 7 (FIG. 5) in the direction opposite to the arrow B, the stud 8 (FIG. 1) is set in the annular groove 1b of the rod 1. The manual setting rod 1 is used to mount the mechanical device of the watch.
Alternatively, it can be removed to remove it from the case. It is done by moving the setting machine 7 (Figure 6) in the same way.
As mentioned above, it is moved during assembly of the device. If the lever 7 is provided with the lug 7bt, the lever can be moved from the dial I11 on the main plate or from the bridge side (inside). Assembly of the components of the embodiment of the device having open slots in the setting locations is performed as follows. A sliding pinion 2 with two limbs is placed on the wall part of the main body of the watch. The lever 7 is set so as to be located under the enlarged canine head 46a of the stuff P6 by the opening portion of the shaped slot. The reversing yoke 10 is freely placed on the bin 11, its arm 10 f't enters the annular groove 2c of the pinion 2, and the elastic arm 10 is fully bent to engage the bin 12. The pin 9 of the setting lever 7 rests in the notch 10m of the yoke 10, and under the action of the elastic arm 10e the lever 7 is moved until it is held by the face 7a of the open slot engaged with the stud 6. The lever 7 is then moved in the direction shown by the arrow B until the stud 6 enters the notch defined by Pull f by a distance that covers more than half the diameter of this rod 1! It gets pulled out. The manual set holder 1 can now be inserted. By moving the setting lever 7 in the direction opposite to arrow B,
The arm 7d is inserted into the annular groove 1b of the rod 1.
