Drive the door to open and close the door, push the door and open and close the door by a link mechanism, drive the decoration by a separate motor, or push out the door and open and close the door with separate motors, and There was also a motor for ornament driving.

As described above, in the decorative clock, in addition to the motor which rotates accurately to drive the clock hands, the stage formation is equipped with several motors for driving the ornament, and as the number of motors increases, the clock becomes large and heavy. On the other hand, when the number of motors is small, the link mechanism is often complicated, and when the link mechanism is relatively simple with a small number of motors, there is a drawback that the movement of a decoration is monotonous.

The present invention eliminates these drawbacks, and provides a door opening and closing mechanism of a decorative clock having a simple structure capable of opening and closing a door with a single motor and driving a decoration.

The present invention is to install a motor to drive the decoration through the gear wheels, in the gear wheels to transfer the rotation of the motor to the gear wheels driving the decoration, two gear wheels are arranged on the same axis and pressed to slip And rotate the one cogwheel arranged on the same axis through the reduction gear cogwheel from the motor to open and close the door by rotation of the other cogwheel arranged on the same axis. A stopper is provided for stopping the movement of the opening and closing door, and the drive transmission gear wheel for driving the decoration is engaged with the cogwheel of the cogwheel or the gear wheel arranged in the same axis engaged with the gear wheel. At this time, in the state in which the opening and closing door is stopped in the fully open position, Slip occurs between the gears.

In addition, it is made into the opening door which divides a clockface into two, and attaches the slider which installed the rack to each opening door, and engages with the gear wheel which is not engaged with the deceleration gear train row in the cogwheel which made the rack of this slider coaxial. do.

The present invention can decelerate the rotation of the motor by a deceleration of the gear wheels and transmit the rotation to one side of the gear wheels arranged on the same axis, and rotate the gear wheels coaxially compressed to the gear wheels.

The opening and closing door can be operated by the rotation of the cogwheel not engaged with the deceleration of the cogwheel of the cogwheel arranged on the same axis, and can be stopped by the operation stopper when the door is fully opened.

In addition, the two cogwheels arranged on the same axis are compressed so as to be slippery, so that when the open door stops in the open position, slippage occurs between these two cogwheels and the rotation of the motor can be continued.

Thus, the rotation of the drive transmission gear wheels, which engages with the cogwheels coaxially engaged with one of the deceleration gear trains or with the deceleration gear trains, is maintained, and the rotation of the drive transmission gear wheels even when the opening door stops in the open position. By this operation of the decoration can be continued.

In addition, the door that divides the dial into two parts can form a large stage by opening the door, so that the rack of the sliders installed on each door can be engaged with the gears that are not engaged with the coaxial gears of the same axis so as to be able to slip. The door can be opened and closed by easily operating the door by the rotation of the cogwheel of the coaxial arrangement.

EXAMPLE

The embodiment of the door opening and closing mechanism according to the present invention is a door opening and closing mechanism of a decorative clock having a dial as an opening and closing door, as shown in FIG.

In this embodiment, the dial is divided up and down from the center, and the upper dial 11 with the opening and closing door is moved upward, the lower dial 12 is moved downward, and the ornament 17 such as a doll disposed on the back of the dial is moved. To form a stage.

As shown in Figs. 2 and 3, the decorative clock is provided with the ornament 17 between the dial and the front plate 22, which are composed of the upper dial 11 and the lower dial 12, and the front plate ( On the front of the front panel 22, an ornament 17, such as a doll or a rotating ornament, is installed, and at the same time, an appropriate figure is drawn in accordance with the ornament 17, and the clock from the watch movement 23 attached to the back of the front plate 22 is displayed. Clock hands 15 are attached to the needle shaft in front of the dial, and two slide rails 31 are fixed in parallel to the substrate 21 fixed to the frame 18, and the respective slide rails ( An upper dial 11 or a lower dial 12 is fixed by a support arm 19 of each slider 33 slidably attached to 31, and the upper and lower dials 11 and 12 are respectively moved up and down. In parallel with the movement of each slider 33 .

Then, the drive of the upper dial 11 and the lower dial 12 as the opening / closing doors form a rack 35 inside the two sliders 33, respectively, and the gear wheel for opening and closing engages with both racks 35. (45) is provided in the center of each slider 33 and each slide rail 31, and the slip gear 43 is provided in the back side of the board | substrate 21 on the same axis as this opening-closing gear 45. As shown in FIG. As shown in FIG. 4, the slip cogwheel 43 inserts and fits the shaft hole of the opening and closing cogwheel 45 into the shaft portion 44 of the slip cogwheel 43, thereby opening and closing the cogwheel. By fitting 45 to the shaft portion 44 of the slip cogwheel 43, the slip cogwheel 43 and the opening and closing cogwheel 45 are rotated integrally when the load is low, but a high load torque is applied. When it is, the slip is generated between the slip cogwheel 43 and the opening and closing cogwheel 45.

In addition, the present embodiment has a reduction gear wheel row 41 which transmits rotation by lowering the rotation speed from the gear wheel 26 attached to the rotation shaft of the door opening / closing motor 25 to the slip gear wheel 43. The link gear which provided in the back side of the board | substrate 21, and provided the drive transmission gearwheel 47 in the slip gear 43 with the other, and provided the groove | channel for a link in this drive transmission gearwheel 47 is also provided. (49) is engaged.

In addition, the link groove of the link gear 49 has a cam shape eccentric at the rotation center of the link gear 49, and the link rod or the like connected to the link groove by the rotation of the link gear 49 is used. By rocking, the ornament 17 installed on the front surface of the front plate 22 is rocked.

In addition, a stopper is formed at one end of the rack 35 attached to the slider 33 so that the engagement between the rack 35 and the opening and closing cogwheel 45 is not misaligned and the movement of the rack 35 is restricted. As the opening and closing door, the movement of the upper dial 11 and the lower dial 12 is restricted so as to stop the opening and closing door in the fully open position.

In addition, in the formation of this stopper, in the embodiment shown in FIG. 3, the protrusion part 36 which does not have a toothed part is formed in the edge part of the rack 35, and the opening-closing gear 45 is attached to the protrusion part 36. In addition, in FIG. When contacted, the engagement of the opening and closing cogwheel 45 and the rack 35 is hindered, and by applying a high load to the rotation of the opening and closing cogwheel 45, the movement of the rack 35 and further the slider 33 is prevented. The upper dial 11 is upward, and the lower dial 12 is stopped downward.

In this embodiment, as described above, the rotation of the motor 25 is transmitted to the slip gear 43 by the speed reduction gear wheel 41, and the opening and closing teeth are fitted and compressed in the same axis as the slip gear 43. The rotation of the slip cogwheel 43 is transmitted to the wheel 45, and the rack 35 or the slider 33 is moved by the rotation of the opening and closing cogwheel 45 so that the upper dial 11 or the lower dial 12 is rotated. ) Is moved up and down, the dial 17 can be divided up and down by the rotation of the motor 25 so that the ornament 17 placed behind the dial can be present.

Further, the slip gear 43 and the drive transmission gear 47 are engaged with each other, and the drive transmission gear 47 or the link gear 49 is rotated in accordance with the rotation of the slip gear 43. Since the link gear 49 rotates the ornament 17 provided at a position away from the clockwise shaft, the link rod is swinged and pushed by the link groove provided in the link gear 49. By moving the rod or the like, movement can be imparted to the ornament 17, and the ornament 17 can be operated at the same time by opening and closing the door by one opening and closing motor 25 by a relatively simple gear train.

Then, when the rack 35 and the slider 33 are moved by the rotation of the opening and closing cogwheel 45, and the protrusion 36 as a stopper is brought into contact with the opening and closing cogwheel 45, the opening and closing cogwheel ( The rotation is stopped by the overload 45, and the open movement of the upper dial 11 or the lower dial 12 is stopped.

Even in the case where the movement of the upper dial 11 and the lower dial 12 of the opening / closing door is stopped as described above, in this embodiment, the rotational speed of the motor is reduced by the reduction gear wheel row 41 to increase the rotation torque. Since the slip gear 43 and the gear wheel 45 for opening and closing are made into a slippery compression structure, even if the rotation of the gear wheel 45 for opening and closing is stopped, the rotation of the slip gear 43 is continued. The opening and closing motor 25 can be continuously rotated, and the ornament 17 can be continuously operated by rotating the drive transmission gear 47 and the link gear 49.

In addition, as shown in FIG. 4, the crimping of the opening and closing cogwheel 45 and the slip cogwheel 43 is performed by the shaft hole of the opening and closing cogwheel 45 in the shaft portion 44 of the slip cogwheel 43. In addition to fitting the shaft shaft of the slip gear 43 to the shaft of the opening and closing gear 45, or fitting the shaft portion of another gear to the shaft hole, It may be attached to the rotating shaft as the same axis by being pressed against each other.

In addition to the case where the drive transmission gear 47 is engaged with the slip gear 43, there are some gears that make the rotational speed mesh with the appropriate gear among the gears constituting the deceleration gear train 41. .

In addition, the stopper for stopping the door in the open position is not limited to the case where the stopper is formed at the end of the rack 35, and the movement of the slider 33 may be limited by forming an appropriate protrusion on the substrate 21 of the watch. In addition, as shown in FIG. 5, in the case of a table clock or the like in which a dial or the like is installed inside the exterior case 27, the upper face of the upper dial 11 is brought into contact with the exterior case 27 so as to open and close the dial. The outer case 27 may also be used as a stopper to restrict movement.

In this embodiment, since the opening / closing door is opened and closed at the same time by one opening / closing motor 25, the decorative object 17 is also driven, so that the clock can be formed compactly, and the gear wheel row and the relatively simple link mechanism and the like are performed. By adding this, the door opening and closing mechanism can also serve as the drive of the ornament 17 easily.

In addition, the movement of the opening / closing door can be divided not only in the case of vertically moving, but also in moving the opening / closing door by dividing the dial into two sides, and moving the opening / closing door left and right. In the case of installing the sliding door to form a window in the portion, and in the case of installing the sliding door in the vicinity of the dial, the door is opened and closed by the rotation of the opening and closing gear 45, and the drive transmission tooth wheel By the rotation of 47, the ornament installed in the inside of the open door can be driven.

In addition, when arrange | positioning an opening / closing door near a dial, for example, by installing a hinge in the right end of a right opening / closing door, and also installing a hinge in the left end of a left opening / closing door, the left / right opening / closing door is a right / left door and the right side from the slider 33 A link rod may be provided as the opening / closing door and the left opening / closing door, and the opening / closing door may be pushed forward by the slider 33 to open the center portion which is a junction between the right opening / closing door and the left opening / closing door.

However, when the entire dial is moved in parallel with the opening / closing door, a large stage can be formed on a small table clock or a wall clock. Especially, when the exterior case 27 is used as a stopper, the moving range of the opening / closing door can be easily increased. It is easy to form a large stage inside the watch.

The present invention utilizes a cogwheel having a coaxial shaft and a cogwheel that engages with one side of the cogwheel coaxial to slip so that the door can be opened and closed by a cogwheel that is not engaged with the cogwheel. Since it is an opening / closing mechanism, even when the door is stopped in the open position, a slip is generated between the cogwheels on the same axis, and the opening / closing mechanism can be maintained to maintain the rotation of the opening / closing motor. It is a door opening and closing mechanism of a decorative clock which can continuously perform the operation of a decoration.

Therefore, there is no need to install a decorative drive motor separately, and it is possible to easily assemble the decorative clock in a small size, and has the advantage of making the decorative clock small in size and light weight.

In addition, the dial is divided into two, and the opening and closing doors, and each of the opening and closing doors are provided with a slider provided with a rack, and a relatively light weight decorative clock that is engaged with the gear wheels not engaged with the decelerating gear train with this rack on the same axis. It has the advantage that a small timepiece can be easily manufactured while forming a stage and greatly changing the timepiece.
