The present invention relates to an improvement of a time setting device for operating an alarm mechanism by a time setting device of a clock, in particular, a relative rotational position between a time difference and a time setting difference, and corrects the present time or time setting time. It is characterized by enabling rotation modification.

The conventional time setting device is operated by a time difference and a time setting that is operated externally to set the time setting needle at a desired setting time by a cam mechanism installed in the time difference and time setting difference, which is operated externally. It consists of a structure which mechanically controls the bushing spring etc. which comprise the time setting contact which controls an alarm mechanism.

In this type of device, since the cam mechanism is not allowed in one direction, the correction direction of time setting correction was limited to one direction, and after 12 hours of correction, the correction rotation was required.

In the conventional apparatus, a latch mechanism is configured to prevent the reversal of the time setting difference, which causes a problem that the configuration is complicated and the number of parts is high. In the conventional apparatus, when the time indicating hand is inverted and corrected, the time setting wheel and the time setting hand may rotate together with the time indicating hand turning due to the time difference and the time setting difference. Too much rotational force is transmitted to this, causing a problem of gear breakage.

An object of the present invention is to prevent the axial movement of the hour hand during the time setting operation at the time setting time, and to correct the time setting time or the present time as the forward setting difference or the forward and reverse rotation of the time difference. do.

In order to achieve this purpose, in the draft, the time difference is rotated once every 12 hours in conjunction with the clock yunyeol and the time difference between the time difference and the time difference can be set coaxially with the time difference to set an arbitrary time setting time. A time setting device comprising a time setting cam arranged freely and axially slidably and a bushing spring for pressing the time setting cam against the time setting difference. The seam cam hole is formed on one side of the cam plane, and the seam cam hole is formed on the other side, and the seam cam part is formed in an inclined surface at which the edge of the seam cam contacting the edge of the seam cam hole at an acute angle with respect to the time-setting cam plane is possible. And a time setting cam structure on either side of the time setting plane and the time setting cam plane opposite to this time setting difference. A bruise is installed and the other side is able to engage with the time setting cam hole, and a time setting cam is formed in which the edge that comes into contact with the edge of the time setting cam hole is formed on an inclined surface at the time of power failure of the time setting cam. When the time difference is reversed, the inclined surface of the sea cam protrusion and the edge of the sea cam hole are engaged, so the time cam is axially slid to release the time click and the time cam hole. It is characterized by enabling rotation modification.

Based on the embodiment of the present invention shown in the following drawings will be described in detail the present invention.

1 shows an embodiment in which the parallax and the time setting difference in the present invention are coaxially arranged with the time indicating needle axis. In FIG. 1, the mechanical difference plate (time setting difference) 14 which has the time setting pipe 12 which can fix a time setting needle at the front-end | tip is hold | maintained by the forward and backward rotation material.

The time setting pipe 12 is made of an elastic member, and the mechanical receiving plate 10 is sandwiched between the plurality of protrusions 12a formed on the main surface thereof and the time setting difference 14, so that the axial movement is impossible. As shown in Fig. 2, the time setting cam 14 is formed with circular arc-shaped time setting cam holes 16 and 18 at different radial positions. The time setting difference 14 is rotated forward and backward by a time setting correction mechanism, which is well known in engagement with a time setting transmission not shown.

The hour hand pipe 20 is united inside the time setting pipe 12, and the time difference 22 is fixed to the hour hand pipe 20.

The parallax 22 has circular arc cam holes 24 and 24 formed at the same radius position as shown in FIG. The edge A direction (electrostatic direction) edge of the sea cam hole 24 is formed in the inclined surface 24a. A small diameter portion 20a and a large diameter portion 20b are formed on the main surface of the hour hand pipe 20, and the axial movement of the parallax 22 in the drawing direction is lowered by engaging the stepped portion 20c with the time setting difference 14. It is set to not possible.

The minute hand pipe 26 is fused to the inside of the hour hand pipe 20, and the minute hand pinion 28 is integrally formed on the minute hand pipe 26 and slip-coupled to the minute hand wheel 30.

The minute hand pipe 26, the minute hand pinion 28, and the minute hand wheel 30 are rotatably stored in the minute hand pipe receiver 34 protruding from the fingerboard 32, and the second hand shaft 35 is disposed inside the minute hand pipe 26. Is coalesced.

A time setting cam 36 is disposed between the time difference 22 and the time setting difference 14, and the time setting cam 36 is rotatably fused to the large diameter portion 20b of the hour hand pipe 20 in the axial direction. It is possible to move.

On one end of the time setting cam 36, two sea cam protrusions 38 engageable with the sea cam hole 24 of the parallax 22 are protruded, and on the other end of the time setting cam hole 16 of the time setting car 14. 18 and 42 are associated with the time setting clicks 40 and 42.

The shape of the time setting click 40.42 is almost the same, and when the time setting click 40 is described, the arrow A direction (electrostatic direction) edge is formed in the inclined surface 40a as shown in FIG. The 40 can be separated from the time setting cam hole 16 as the inclined surface 40a is raised on the vertical surface 16a.

The other edge of the time setting click 40 is formed in the vertical surface 40b, and this vertical surface 40b is formed in the vertical edge 60b which can fall.

On the other hand, as shown in Fig. 5, the shape of the sea cam protrusion 38 of the time setting cam 36 is formed as an inclined surface 38a formed by cutting the base of the arrow A direction (electrostatic propulsion) edge, and the other edge is a vertical plane. It is formed of 38b.

In the parallax 22, the edge A direction edge of the sea cam hole 24 is formed by the inclined surface 24a, and the other edge is formed by the vertical surface 24b.

The vertical surface 38b of the shicam protrusion 38 is generally pressed in the direction of arrow A in engagement with the vertical surface 24b of the shicam hole 24.

The conductive bushing spring 44 and the fixed contact plate 48 are fixed to the instrument receiving plate 10, and although not shown, are connected to a power source and an alarm sound generating device through lead agitation.

The bushing spring 44 pushes the time setting cam 36 in the direction of the time setting difference 14, and the time setting clicks 40 and 42 of the time setting cam 36 set the time of the time setting difference 14. The contact 46 is set in contact with the stationary contact plate 48 by falling into the cam holes 16 and 18.

The illustrated embodiment is configured as described above and the operation thereof will be described next.

In FIG. 1, the present time is about 20 minutes before the time setting time. In this state, as shown in FIG. 6, the time setting cam 36 is pressed against the vertical surface 24b of the parallax 22, and the sea cam protrusion 38 rotates integrally with the parallax 22. As shown in FIG.

Thus, part of the time setting clicks 40 and 42 of the time setting cam 36 is polymerized in the time setting cam holes 16 and 18 of the time setting difference 14. When the time difference 22 reaches the time setting time, as shown in FIG. 7, the time setting clicks 40 and 42 of the time setting cam 36 are perpendicular to the time setting cam holes 16 and 18 in the planes 40b and 42b. The alarm sound generator, not shown, is operated by dropping and thereby the bushing spring 44 and the fixed contact plate 48 contact each other. When the time setting click 40 of the time setting cam 36 deviates from the time setting difference 14 and the time setting cam hole 16, the inclined surface 40a is placed on the vertical surface 16a as shown in FIG. It is done by being raised.

Next, the correction of the present time and the time setting time will be described. Therefore, since the combination relationship between the time setting clicks 40 and 42 and the time setting cam holes 16 and 18 are the same, only one combination will be described. The present time correction was performed by the minute hand pinion 28 by forward and reverse rotation of the external crystal handle by a conventional well-known correction mechanism.

When the parallax 22 rotates in the arrow A direction by the correction mechanism, the time setting cam 36 rotates in the same direction as the parallax 22.

At this time, as shown in FIG. 8, the time setting click 40 falls to the time setting cam hole 16, but the time setting click 40 has the inclined surface 40a at the vertical surface 16a of the time setting cam hole 16. As it is raised, it is separated from the time setting cam hole 16, and the electrostatic direction correction of the time indicating hand is performed. The inversion of the indicator hand is performed by rotating the parallax 22 in the arrow B direction (reverse direction) as shown in FIG.

At this time, in the time setting cam 36, the inclined surface 38a of the sea cam protrusion 38 is pressed against the bottom of the inclined surface 24a of the sea cam hole 24 to rotate integrally with the parallax 22.

The time setting click (40) of the time setting cam (36) falls from the inclined surface (40a) to the time setting cam hole (16) of the time setting difference (14), and the vertical surface (16b) of the time setting cam hole (16) and the time. When the vertical surface 40b of the setting click 40 abuts, the inclined surface 38a of the sea cam protrusion 38 is raised on the inclined surface 24a of the sea cam hole 24.

As a result, the time setting cam 36 moves upward in the city, whereby the time setting click 40 is released from the time setting cam hole 16, and thus the time setting cam 36 and the time difference 22 ) Is rotated in the direction of arrow B.

In this way, the present time can be corrected by rotating the indicator hand forward and backward.

Next, correction of the time setting time will be described. In the correction for rotating the clock set hand in the electrostatic direction, the clock set difference 14 rotates in the direction of arrow C as shown in FIG.

At this time, the vertical surface 38b of the sea cam protrusion 38 of the time setting cam 36 is engaged with the vertical surface 24b of the sea cam hole 24, but the parallax 22 is engaged with the minute wheel (not shown). Therefore, a large torque is required.

The time setting difference 14 is rotated in the direction of the arrow C, and after the time setting click 40 falls to the time setting cam hole 16, the time setting click 40 has the inclined surface 40a of the time setting cam hole 16. It is pressed by the vertical surface 16a, and is raised to the upper direction of illustration.

Accordingly, the time setting click 40 can be released from the time setting cam hole 16. In this way, rotation correction in the direction of the arrow C of the time difference is performed.

In the correction for rotating the clock setting hand in the reverse direction, the clock setting difference 14 rotates in the direction of the arrow D as shown in FIG. At this time, in the time setting cam 36, the vertical surface 40b of the time setting click 40 is pressed against the vertical surface 16b of the time setting cam hole 16, and rotates in the arrow D direction.

When the inclined surface 38a of the sea cam protrusion 38 is in contact with the inclined surface 24a of the sea cam hole 24, the sea cam protrusion 38 is placed on the inclined surface 24a, whereby the time setting cam 36 is shown in the image. Move in the direction of

As a result, the time setting click 40 can be disengaged from the time setting cam hole 16. In this manner, the time setting time can be performed by rotating the indicator hand forward and backward. Therefore, since the latch mechanism for rotating in the conventional one direction is unnecessary, the number of parts is reduced.

In addition, damage to the gear portion caused by reversing the conventional indicator hand is also reduced.

In the illustrated embodiment, the electrostatic direction edge of the sea cam hole 24 in the time setting cam 36 is clicked on the time setting as shown in FIG. 10 of the sea cam protrusion 38 in the time setting cam 36. The vertical surface 24c may be sufficient as it is possible to penetrate above the parallax 22 even when the 40 is in the falling state to the time setting cam hole 16. In the illustrated embodiment, the sea cam hole 24 and the time setting cam hole 16 are laid in the time difference 22 and the time setting difference 14, respectively, and the sea cam protrusion 38 and the time setting are clicked on the time setting cam 36. Although 40 and 42 are formed, the following configurations are also possible as other configurations. That is, the sea cam protrusion 38 and the time setting clicks 40 and 42 are formed in the time setting difference 14 of the time difference 22, respectively, so that the time cam hole 24 and the time setting cam hole ( Even if the structure 16 and 18 is installed, it has the same effect as the illustrated embodiment. Incidentally, in the illustrated embodiment, the time difference 22 and the time setting difference 14 are arranged on the same axis as the time indicating hand, but this may be arranged on different axes.

As a result, the time setting cam 36 on the time indicating axis is arranged on different axes, so that the clock mechanism can be made thinner by the thickness of the time setting cam 36.

As described above, according to the present invention, a time setting cam that is movable in the axial direction is disposed between the time difference and the time setting difference, and the sea cam protrusion protruding from the time setting cam is always engaged with the sea cam hole installed in the time difference. The inclined surface of one side of the seam cam portion can be raised to the edge of the seam cam hole by the configuration of the inclined surface of the seam cam part. Accordingly, only the time setting cam can be moved to reversely rotate the time setting difference and the time setting cam. Reverse rotation correction of the time or time setting time is now possible. Also, by disposing the parallax and the time setting difference on an axis different from the visual indicator hand axis, the clock mechanism can be made thinner. In addition, since the parallax and the time setting difference cannot be moved in the axial direction, the indicator hand does not move during operation of the time setting device so that it is easy to see. In addition, since the ratchet mechanism required to perform the conventional one-way rotation is unnecessary, the number of parts is also reduced.
