[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a decoration device for a mechanical timepiece that moves or rotates decorations such as various dolls and promotes the decoration effect with the fun and enjoyment of the movement.

[0002]

[Prior art]

 Conventionally, as this type of decoration device, for example, ones shown in FIGS. 9 and 10 have been known.

In the device shown in FIG. 9, a decorative body 1 such as a doll is attached to a movable plate 2, and two yarns 4 attached to the movable plate 2 are halved to two pulleys 4 provided on both sides of a lower plate 3. The two ends of the thread 5 are fixed to the thread stopper plate 6, and one end of the thread stopper plate 6 is rotatably attached to the moving plate 2 for eccentric rotation to support three points. The stoppers 7 are arranged on both sides of the plate 3, and the movable plate 2 attached to the yarn 5 by the motor 8 between the stoppers 7, that is, the decorative body 1 is configured to reciprocate linearly and swing. See Japanese Utility Model Publication No. 3-42589).

Further, in the apparatus of FIG. 10, the base plate 12 having a decorative body that slides along the guide 11 having the stopper pins 11a and 11b formed at both ends is different from the base plate 12 having the stopper 11a and 11b.

[0005]

[Problems to be solved by the device]

 However, since the above-described conventional decoration device moves straight and reciprocally at a fixed position in a fixed section, the decoration body 1 such as a doll cannot be attached over the entire circumference of the thread or belt. However, there is a problem that the number of attachments of the decorative body 1 is limited, and the movement is limited to rocking or short-distance reciprocating movement. Therefore, there is a problem that it is necessary to complicate the structure in order to make the movement of the ornamental body more complicated and more precise and interesting.

Further, in the above-described conventional decoration device, since the yarn 5 or the belt is likely to be loosened, there is a problem that the movement of the decoration body is not smoothly performed. In order to solve this problem, there has been conventionally proposed a structure in which a belt slack correction mechanism that applies a predetermined pressing force for correcting slack to the belt from the outer peripheral side of the belt is provided. However, in this belt slack correction mechanism, a pressing force is applied to a part of the belt by means of a pin or the like, which causes a problem that the device itself becomes large and complicated.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a simple structure, increase the number of attachments of a decorative body, and obtain a precise and interesting movement of the decorative body. It is possible to correct the slack of the belt with a simple structure, and to provide a decoration device for a mechanical timepiece that can prevent the size and complexity from being increased.

[0008]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, in the present invention, a base plate having an endless guide portion and a base plate pivotally supported by the base plate are rotatable in forward and reverse directions, and at least two of which rotate in the same direction at the time of rotation. At least one ornamental body mounted with a rotary power transmission body, an endless belt hung between the rotary power transmission bodies, and a sliding portion mounted on the endless belt and sliding along the guide portion. An elastic force smaller than the rotational force in the direction of the contact area from the shaft portion to the endless belt, which is provided in the bearing portion of the member and at least one of the plurality of rotary transmission bodies. And a belt slack correcting means for urging the belt.

[0009]

[Action]

 According to the present invention, one or a plurality of ornamental body attachment members are attached to arbitrary positions of the endless belt, and various ornamental bodies can be fixedly or detachably attached to these ornamental body attachment members and rotated. Can be mounted as possible. The endless belt to which the decorative body mounting member is thus mounted is hung between the rotary transmission bodies. In this state, the endless belt is controlled to rotate in the forward and reverse directions and in an arbitrary direction, so that the ornamental body attached to the ornamental body attaching member is given an interesting movement. At this time, the sliding portion formed on the decorative body mounting member slides along the guide portion formed on the main plate. That is, the ornament attachment member forms a predetermined circular locus. Further, since the rotary transmission body around which the endless belt is stretched is urged by its bearing portion with an elastic force smaller than the rotational force in the direction of the contact area with the endless belt, the slack of the endless belt is constantly corrected. . Therefore, the movement of moving the ornament is smoothly performed.

A slide pin for an upper plate, which will be described later, formed on the ornament mounting member 107 is inserted into the guide groove 103a, and the guide groove 103a moves the slide pin for the upper plate along the rotation locus of the timing belt 104. And guide in an oval shape.

FIG. 6 shows an enlarged cross-section in the direction of arrow AA shown in FIG. 2 when the ornament attachment member 107 is located on the side of the apparatus.

The decorative body mounting member 107 includes a main body 107a, a decorative body mounting shaft 107b, and a receiving plate sliding portion 107c. The configuration of each unit will be described below with reference to FIGS.

The main body 107a has a substantially cubic shape, and a pair of lower plate sliding pins 107a1 is formed below one side surface side, and a pair of upper plate sliding pins 107a2 is formed above. There is. As shown in FIG. 4, an engaging portion 107a3 for attaching to the timing belt 104 is formed between the pair of lower plate sliding pins 107a1 and between the upper plate sliding pins 107a2. ing. On the other surface side of the main body 107a facing the above one side surface, a shaft is formed in a direction orthogonal to the rotation direction of the timing bell 104 in a state of being attached to a timing belt, and a decoration mounting shaft 107b is rotatable. A through hole 107a4 is provided to be inserted into the hole.

The decorative body mounting shaft 107b is made of, for example, a substantially cylindrical metal, is inserted into the through hole 107a4 of the main body 107a as described above, and has dolls A1 to A4 as decorative bodies on the upper end thereof. B1 to B4 are detachably formed with a doll mounting portion 107b1 having a flat surface, and a receiving plate sliding portion 107c is press-fitted into the lower end portion. Therefore, the ornament attachment shaft 107b rotates integrally with the doll attached to the through hole 107a4 of the main body 107a.

The receiving plate sliding portion 107c is made of, for example, the same resin as the main body 107a, and as shown in FIG. 7, a shaft having a press-fitting hole 107c11 into which the lower end of the ornament mounting shaft 107b is press-fitted. The mounting portion 107c1, the receiving plate upper surface sliding portion 107c2 formed in a crank shape at the lower end of the shaft mounting portion 107c1 so as to be orthogonal to the axis of the press-fitting hole 107c11, and its cross section is formed in a substantially triangular shape. An end of the plate upper surface sliding portion 107c2 is formed so as to project to the lower surface side and is configured by a sliding pin 107c3 inserted into the guide portion 101c of the receiving plate 101.

As shown in FIG. 8, the member attachment 108 is formed in a substantially U-shape in which both ends of a flat plate spring are bent in the same direction and at a right angle. Locking holes 108a1 and 108b1 that are locked to a pair of locking portions 107a3 formed above and below the front surface of the main body 107a of the ornament mounting member 107 are formed in the upper and lower bent portions 108a and 108b, respectively. A hub insertion hole 108c1 into which the hub 104a of the timing belt 104 can be inserted is formed in the flat plate portion 108c between the bent portions 108a and 108b. The length of the flat plate portion 108c in the longitudinal direction is set to be slightly longer than the width of the timing belt 104.

To attach the ornamental body attaching member 107 using this member attaching tool 108, for example, it is performed as follows. In other words, one of the hubs 104a formed on the inner surface of the belt and meshing with the teeth of the pulleys 105 and 106 is inserted into the hub insertion hole 108c1 of the member attachment 108, and the timing belt 104 is inserted. The ornamental body mounting member 107 is located on the outer surface side of the body, and the locking holes 108a1 and 108b1 are locked to the pair of locking portions 107a3 formed on the upper and lower sides of the front surface of the main body 107a of the decorative body mounting member 107. It As a result, the attachment of the decorative body attaching member 107 to the timing belt is simply completed.

In the same manner as described above, a plurality of decorative body mounting members 107 are mounted on the endless timing belt 104, and the sliding pins 107c3 of the receiving plate sliding portions 107c of the respective decorative body mounting members 107 are received by the receiving plate 101. Is inserted in the guide portion 101c of the. In the case of the present embodiment, as shown in FIGS. 2 and 4, eight ornamental body attachment members 107 are attached to the timing belt 104. Then, the timing belt 104 is attached between the pulleys 105 and 106 at a predetermined interval of four on the front side and four on the rear side, for example, four ornamental body attachment members 107 on one side. Female dolls A1 to A4 in national costumes are attached to the four dolls, and male dolls B1 to B4 forming a drum and flute corps are attached to the four decorative body attachment members 107 on the other side.

In the decoration device configured as described above, the wiring for the motor 112 and the like are connected to a control system (not shown) provided in the main body of the timepiece mechanism. In this apparatus, a doll A1 to A4, B1 to B4 is made to stand by by a control system (not shown) in a positional relationship shown in FIG. 2 at times other than the hour, and the motor 112 is driven at the hour. It controls the transfer and replacement of the dolls located on the rear side to the front side, and controls the reciprocating motion within a predetermined range.

Next, an operation example with the above configuration will be described. For example, when the hour is on the hour in the initial state as shown in FIG. 2, the motor 112 is driven by the control system and the dolls B1 to B4 located on the rear side of the device move counterclockwise to the front side. The dolls B1 to B4 and A1 to A4 are switched to each other and temporarily stopped.

Next, the rotation direction of the motor 112 is switched at predetermined intervals. As a result, the dolls B1 to B4 (A1 to A4) are reciprocated for a predetermined distance. This reciprocating distance is, for example, a distance corresponding to two cams 101d in the triangular wave-shaped guide portion 101c shown in FIG.

When the rotation direction of the timing belt 104 is counterclockwise or clockwise in FIG. 2, the receiving plate upper surface sliding portion 107c2 and the sliding pin 17c3 of the receiving plate sliding portion 107c of the ornamental body mounting member 107 advance. It slides along the guide groove 101c so as to be located rearward of the doll attached to the ornament mounting shaft 107b in the direction. Immediately after the direction of rotation is reversed, when the receiving plate upper surface sliding portion 107c2 and the sliding pin 17c3 are located in front of the doll attached to the ornament mounting shaft 107b in the traveling direction, In the next cam 101d, the direction is reversed while the sliding is temporarily stopped. That is, by the cam 101d, the receiving plate upper surface sliding portion 107c2 and the sliding pin 17c3 are located rearward of the doll attached to the ornament mounting shaft 107b in the traveling direction and slide along the guide groove 101c. Modified to work.

Note that the sliding pins 107a1 and 107a2 are inserted into the guide groove 102f of the lower plate 102 and the guide groove 103a of the upper plate 103 of the main body 107a of the ornamental body mounting member 107 regardless of the right or left rotation direction. Since it slides along these guide grooves 102f and 103a, it is rotated while drawing an elliptical locus almost similar to the timing belt 104.

Here, the movement of the doll will be considered. In the counterclockwise direction, when the receiving plate upper surface sliding portion 107c2 and the sliding pin 107c3 are sliding between the two cams 101d, for example, along the guide groove 101c rising to the right in FIG. Since the movement of the lower end of the mounting shaft 107b is restricted by the movement of the sliding pin 107c3 inserted in the guide portion 101c, the decorative body mounting shaft 107b rotates clockwise. That is, the doll is rotated to the right. In this state, when the sliding pin 107c3 reaches the next cam 101d, the rotating direction of the decorative body mounting shaft 107b is reversed, and the sliding pin 107c3 slides along the guide portion 101c descending to the right to move to the next cam 101d. It rotates counterclockwise until it reaches the cam 101d. That is, the doll rotates counterclockwise.

Similarly, in the case of clockwise rotation, when the receiving plate upper surface sliding portion 107c2 and the sliding pin 107c3 are sliding along the guide groove 101c descending to the right, the ornamental body mounting shaft 107b. Since the movement of the lower end of the decorative body mounting shaft 107b is restricted by the movement of the sliding pin 107c 3 inserted in the guide portion 101c, the ornamental body mounting shaft 107b rotates clockwise. That is, the doll is rotated to the right. In this state, when the sliding pin 107c3 reaches the next cam 101d, the rotating direction of the decorative body mounting shaft 107b is reversed, and the sliding pin 107c3 slides along the guide portion 101c rising to the right to move to the next cam. It rotates counterclockwise until it reaches the cam 101d. That is, the doll rotates counterclockwise.

Therefore, the dolls B1 to B4 (or A1 to A4) located on the front side of the device change the left and right rotation directions with the cam 101d as a boundary during the reciprocating motion described above. , It will be a precise and interesting movement.

After such a precise and interesting reciprocating motion is performed for a predetermined time, it is temporarily stopped, then the dolls are replaced again, and the above-described reciprocating motion is performed. After the above operation is repeated several times for each hour, the state as shown in FIG. 2 is maintained and the operation stands by until the next hour.

Even when the dolls waiting on the rear side of the apparatus are not oriented in the same direction, for example, their faces are not aligned, the cam 101e provided on the rear side of the apparatus aligns them in one direction and the dolls are conveyed to the front side of the apparatus. .

As described above, according to the present embodiment, the endless timing belt 104 is sandwiched between the member attachment 108 having a U-shaped leaf spring and the main body 107 a of the ornament attachment member 107. Then, the ornamental body attaching member 107 is attached to the endless timing belt 104, and the timing belt 104 is hung between the pulleys 105 and 106 which are rotated in the forward and reverse directions by the motor 112. Since the sliding pins 107a1 and 107a2 of the main body 107a of the material 107 are configured to slide along the guide groove 102f of the lower plate 102 and the guide groove 103a of the upper plate 103, respectively, the timing belt 104 can be entirely covered. It is possible to attach ornaments such as multiple dolls. Therefore, it is possible to relax the restriction on the number of attachments of the ornament, and to obtain a precise and interesting movement of the ornament with a simple structure. Further, since the weights of the decorative body attaching member 107 and the dolls A and B are supported via the sliding pins 107c3, they do not affect the timing belt 104. If the dolls A and B have a heavy weight, the load can be reduced by providing the sliding pin with a rotating member. In addition, the decoration can be easily changed.

Furthermore, a part of the outer side of the longitudinal axis of the lower plate 102 of the pulley mounting shaft 102b of the pulley 106 is opened, and the inner diameter of the shaft hole 106a of the pulley 106 is the outer diameter of the pulley mounting shaft 102b. When the pulley 106 is set larger, the pulley 106 is inserted between the inner wall of the inner portion of the longitudinal axis of the lower plate 102 of the pulley mounting shaft 102b and the inner wall of the shaft hole 106a of the pulley 106 from the shaft hole side to the timing belt 104. Since the pressing spring 109 as a belt slack correcting means for urging the elastic member having a smaller elastic force than the rotational force in the direction of the outermost contact area with is inserted, the slack of the timing belt 104 is surely corrected with a simple structure. it can. Therefore, the movement of the dolls A and B can be further smoothed.

In addition, one of the hubs 104a formed on the inner surface of the belt and meshing with the teeth of the pulleys 105 and 106 is inserted into the hub insertion hole 108c1 of the member mounting member 108, and the timing belt The timing belt 104 is locked by locking the locking holes 108a1 and 108b1 to the pair of locking portions 107a3 formed above and below the front surface of the main body 107a of the decorative body mounting member 107 located on the outer surface side of the timing belt 104. Since the decorative body attaching member 107 and the decorative body attaching member 107 are elastically coupled to each other, the decorative body attaching member 107 can be easily attached to the timing belt. Therefore, it is possible to easily change the attachment positions and intervals of the ornaments, and it is possible to realize a versatile ornamental device.

Further, an endless guide groove 101c having an oval shape is formed on the upper surface of the receiving plate 101, and a region of the guide groove 101c over the entire longitudinal direction on the front side of the device is formed in a so-called triangular waveform. A rectangular cam 101d is formed at each apex portion so as to extend outward from the apex, and the lower end of the ornamental body attaching shaft 107b of the ornamental body attaching member 107 is formed into a crank shape, and the tip end thereof receives the receiving plate 101. Since the receiving plate sliding portion 107c having the sliding pin 107c3 that is inserted and slides in the guide groove 101c is attached, the ornamental body conveyed to the front side of the apparatus can be reciprocated by a predetermined distance to rotate it. The direction changes swiftly between right and left, enabling precise, fun, and interesting movements.

The guide groove 101c on the rear side of the apparatus is formed in a linear shape, and both end portions of the linear area are formed in a triangular wave shape so that the apexes are located inside the receiving plate 101, and Since a square-shaped cam 101e is formed at each apex that is continuous in the outward direction of the apex, even if the orientation of the doll waiting on the rear side of the equipment is not uniform, for example, even if the faces are not aligned By the cam 101e provided on the side, it can be aligned in one direction and conveyed to the front side of the apparatus.

In the present embodiment, the cams 101d and 101e formed in the guide groove 101c of the receiving plate 101 are formed as rectangular grooves, but the present invention is not limited to this, and it is not limited to this. As long as it can hold the stopped state once, if it can hold the stopped state by giving a predetermined frictional force to the sliding pin 107c3, for example, even if only the apex of an acute triangle is used, The reversing action of the above-mentioned receiving plate upper surface sliding portion 107c2 can be revealed. Needless to say, the number of decorative bodies, the arrangement position, the operation control, and the like are not limited to those in this embodiment.
