Description

[Detailed description of the invention] (Industrial application field) This invention is a music box toy with a light emitting part,
Specifically, the present invention relates to a music box toy that has a light emitting part and has movement.

(Prior Art) Music box toys whose light emitting parts light up or blink when the music box plays are already known.

(Problems to be solved by the invention) Conventional light-emitting music box toys have the problem that they lack interest as a toy because the music box only plays and the light-emitting part lights up or flashes, but there is no movement. Ta.

The purpose of the present invention is to provide a light-emitting music box toy that is operated using the release force of Zenmai, which is the driving source of the music box, and is more interesting as a toy.

(Means for Solving the Problems) The light-emitting music box toy of the present invention houses a lamp, a battery for powering the lamp, a switch provided between the lamp and the battery, and a music box movement that is driven by the entire movement. a main body that supports the main body in a swingable manner by supporting the full winding shaft of the music box movement with a bearing part; an actuating cam that is in contact with the main body and rotates by the release force of the Zenmai to swing the main body with respect to the support body; a Geneva stop mechanism that regulates the rotation angle of the Zenpa winding upper shaft; It is rotated by the Geneva gear, and during full release, one contact piece of the switch is pushed in the direction of contacting the other contact piece, and at the end of full release, one contact piece of the switch is pushed into contact with the other contact piece. It consists of a switching cam that allows the switch to move away from the other contact piece, and a manual knob that pushes the other contact piece of the switch in a direction that causes it to move toward and away from the one contact piece.

(Function) Winds up the entire music box movement.
At this time, the rotation angle of the winding shaft is regulated by the Geneva stop mechanism. When you release your hand from the winding shaft, the music box movement will play due to the full release force, the operating cam will rotate and the main body will swing relative to the support, and the switching cam will move one contact piece of the switch. Touch the other contact piece to light the lamp. The sound of the above music box movement,
The rocking of the main body and the lighting of the lamp continue until the Geneva stop mechanism restricts the rotation of the winding shaft in the release direction. At the end of the full release, the switching cam releases one contact piece from the other contact piece, thereby extinguishing the lamp. When it is desired to check the condition of the power supply battery (battery check), the manual knob is pressed to bring the other contact piece into contact with one contact piece.

As shown in Fig. 4, the movement mounting part 3
bh is formed and the tapping screw 19,1
A music box movement 20 is fixed by 9 and 19.

As shown in FIGS. 4 and 6, the music box movement 20 includes a frame 21, a barrel 22 which is fixed to the frame and houses a Zendan (not shown), and one end of which is connected to a Zendan (not shown). The upper shaft 23 has one end 23a protruding from the frame 21 and the other end 23b from the upper surface of the barrel, and a bevel gear 25 fixed to one end of the upper shaft 23 is connected to a gear inside the barrel (see Fig. (not shown)
a drum 24 which is engaged with the drum 24 and whose other end is rotatably supported by the frame 21 by a support shaft 26;
The governor mechanism 28 consists of a speed-increasing gear train 28a that speeds up the rotation of the drum and a wind blower 28b, and a diaphragm 21a that is fixed to the frame 21 and whose tip is placed close to the drum 24. There is. A spur gear 27 is press-fitted and fixed to the end 26a of the support shaft 26 of the drum.

The spur gear 27 meshes with the crown tooth portion 29a of the actuating cam 29. The operating cam 29 is rotatably supported by a support shaft 3bi (see FIG. 4) formed in the lower part 3bb of the rear case. The operating cam 29 has a cam portion 29b formed of a heart cam. As shown in FIG. 4, cam receiving parts 3bj, 3bj, 3bj are formed on the support shaft 3bi, and by receiving the end face of the cam part 29b with the side edge 3bk, the operating cam 29 can be backed up. There is.

As shown in FIG. 4, a square shaft portion 30 is formed at one end 23a of the full-length drive shaft 23. As shown in FIG. This square shaft portion 30 is connected to the disk 31 of the Geneva stop mechanism 31.
Square hole 31b formed in one boss portion 31e of a
is fitted to the The disk 31a is formed with an actuating protrusion 31f projecting from the disk, and the other boss portion 31c is formed with a square shaft portion 31d. The boss portion 31e is rotatably inserted into the bearing hole 3be of the rear case. As shown in FIGS. 2, 4, and 5, a square shaft portion 31d protruding from the rear case 3bb has a square hole 32a fitted with a full winding upper knob 32, and a fixing screw 32
It is fixed by b. Therefore, the full-length winding upper shaft 23, the disc 31, and the full-length winding upper knob 32 are substantially integrated.

The boss portion 31e of the disc 31a is rotatably supported by a bearing portion 33a formed at the upper end of the rear clamp 33, as shown in FIGS. 2, 4, and 5. The rear clamp 33 and the front clamp 34 constitute the support body 2. The front clamp 34 has one end 23b of the full winding shaft inserted through a bearing portion 34a formed at the upper end of the front clamp 34, thereby rotatably supporting the front clamp 34. The bearing portion 34a is located in the bearing hole 8a of the middle plate 8.
is loosely fitted. Therefore, by rotatably supporting the full winding shaft 23 of the music box movement 20 on the support body 3, that is, the front clamp 34 and the rear clamp 33, the main body 3 can swing freely with respect to the support body 2. It will be supported. Since the bearing portion 34a and the bearing hole 8a of the intermediate plate 8 are loosely fitted, the main body 2 is supported by the support body 3 in a substantially cantilevered state. In addition, by arranging the batteries 43a and 43b at the upper part of the upper winding shaft 23 and the music box movement 20 at the lower part (see Fig. 3), the weight of the main body 3 is balanced and the rotational moment is reduced. There is. This means that the main body 3 can be swung with a small driving force. Among the axes of the music box movement, the axis to which the largest torque is applied, in other words, the Zenbu winding upper axis 2 is the one that is given the most strength.
By using 3 as the central pivot axis O of the main body 3 (see Fig. 4), the strength of the swingable connection between the main body 3 and the support 2 is increased, and the drop resistance of the entire toy is increased. .

As shown in FIGS. 2, 4, and 5, the front clamp 34 and the rear clamp 33 are connected to a connecting portion 34b.
and 33b, and are integrally fixed to each other by fixing screws 35. The lower part 33c of the rear clamp 33 and the lower part 34c of the front clamp 34 are spaced apart from each other and are provided parallel to each other, and are designed to straddle, for example, the railing of a baby bed indicated by reference numeral B in FIG. A band 36 is passed through the front clamp 34. On the other hand, a hook 33d is formed at the lower part of the rear clamp 33 to engage the hole 36a of the band 36, so that the support 2 straddled over the fence B can be fixed with the band. The lower parts of the front clamp 34 and the rear clamp 33 are located outside the main body 3, and the upper parts thereof are located inside the main body. Since the main body 3 is swingably provided with respect to the support 2, a gap is formed at the bottom of the main body along the swinging direction. On both sides of the rear clamp 33, there are covers 3 located inside the main body to close the above-mentioned gap.
3i and 33i (see FIG. 4) are formed.

A torsion spring 37 is wound around a boss portion 33e of the rear clamp in which a bearing portion 33a is formed. The torsion spring 37 has one end 37a locked in a locking portion 33f formed on the rear clamp 33, and the other end 37b engaged in a partition wall 3bc of the rear case (see FIGS. 2 and 13). .

The boss portion 33e of the rear clamp 33 has the markings shown in FIG.
As shown in FIGS. 4 and 5, a buffer plate 38 is rotatably inserted. This buffer plate 38 has its elongated hole 38a connected to a pin 33 formed in the rear clamp.
It is fitted in g. A flanged tubbing screw 39 is screwed into the pin 33g to slidably guide the buffer plate. A spring receiving portion 38b is formed in the buffer plate 38, and accommodates an extensible coil spring 40. One end 40a of the spring 40 is
By being engaged with a stopper 33h formed on the rear clamp, the buffer plate is pushed within the range of the elongated hole. A cam stop 38c is formed on the buffer plate 38. As shown in FIGS. 13 and 14, the cam portion 29b of the operating cam 29, which is biased by a torsion spring 37 and rotatably supported by the main body, is brought into contact with this cam stop 38c. There is. That is, the main body 3 has the above-mentioned torsion spring 3
Due to the elasticity 7, in FIG. 13, a clockwise rocking habit is given about the rocking center axis O (full winding upper shaft 23). The details will be described later, but due to this sliding behavior, the main body 3
is positioned at the home position shown by the solid line in FIG. 1 when the full range is released.

In FIGS. 4, 6, and 7, a Geneva gear 41 of a Geneva stop mechanism 31 is rotatably supported on a support shaft 3BL formed in a lower portion 3BB of the rear case. The Geneva gear 41 has four grooves 41a, 41 that engage with the operating protrusion 31f of the disc 31.
b, 41c, 41d, and three arcuate portions 41e, 41f, 41g having the same arc as the arc of the disk 31.
and a stopper 41h that interferes with the arc of the disc 30. Further, a switching cam 42 is integrally formed with the Geneva gear 41.
The switching cam 42 has a cam portion 42a formed therein. At the full release end (home position) where the full range (not shown) is released, the Geneva stop mechanism 31 is in a state where the actuating protrusion 31f is engaged with the groove 41a, as shown in FIG. The stopper 41h interferes with and engages with the circular arc 31g of the disk (shown separated in FIG. 7).

The configuration of the switch 44 will be explained with reference to FIGS. 4 and 7. One of the contact pieces 44a extending from the base of the contact piece 15 has its tip in sliding contact with the circumferential surface of the operating cam 42, and in the home position, its bent tip is fitted into the cam part 42a. ing. The other contact piece 44b extending from the base of the contact piece 14 extends parallel to the one contact piece 44a, and its tip 44c is held between the pair of protrusions 10b, 10b of the manual knob 10.

As shown in FIGS. 3 and 4, the hand-operated knob 10 is held in such a manner that the knob 10a is fitted into the elongated hole 3bf and held in place by a holding portion 46a of a holding member 46. The holding member 46 is fixed to the lower part 3bb of the rear case with a tapping screw 45. As shown in FIGS. 6, 7, and 10, the holding member 46 has a positioning protrusion 46b formed at its tip that engages and disengages with the groove 10c of the manual knob 10, and has an elastic positioning arm. 46
c is provided. The manual operation knob 10 is the first
As shown in FIG. 0, when the groove 10c is engaged with the positioning protrusion 46b, the other contact piece 44b is moved away from the one contact piece 44a and held in the off position. In this off position, the circumferential surface 42b of the cam 42 is
Even if you push 4a as shown by the chain line, the switch 44
is not turned on. As shown in FIG. 11, when the manual knob 10 is placed in the switch-on position where the groove 10c and the protrusion 46b are disengaged,
The other contact piece 44b is brought close to the one contact piece 44a, but only when the one contact piece 44a is pushed by the circumferential surface 42b of the operating cam, both contact pieces come into contact and close the switch 44. It has become like this,
When one contact piece 44a is fitted into the cam portion 42a, both contact pieces are placed at separate positions.

Further, as shown in FIG. 10, a protrusion 10d of the manual operation knob 10 is provided on the presser part of the presser member 46.
By fitting these, a groove 46d is formed to restrict movement of the knob to the left in the figure. The presser member 46 also includes a Geneva gear 41.
a protrusion 46e for preventing the pressing member 4 from falling off;
Pins 46f are formed to prevent the parts 6a from floating up. As shown in FIG. 3, this pin 46f is brought into contact with the bottom surface of the frame 21 of the music box movement.

In the embodiment described above, the clamps 33, 34
Although the support body 2 equipped with the above-mentioned support body 2 has been described, it goes without saying that the support body of the present invention may be a support body that can be placed on a tabletop or a floor, that is, a stationary support body. Further, although a cam integrated with the Geneva gear 41 has been described as the switching cam, it may be a separate cam that is gear-coupled to the Geneva gear, for example. Furthermore, in the illustrated embodiment, the sliding behavior in the direction in which the operating cam 29 of the main body 3 comes into contact with the cam contact 38c of the support body is provided by the elasticity of the torsion spring 37, but as shown in FIG. As shown in FIG. 2, the music box movement 20 can be arranged to be deviated from the center of the rocking axis O of the main body, thereby imparting a rotational moment to the main body. In this case, the torsion spring 37 as a means for bringing the actuating cam into contact with the support is not necessarily required.

The operation of the embodiment configured as above will be explained.

First, it is assumed that the main body 3 is placed at the home position shown by the solid line in FIG. At this time, the operating cam 29 brings the lower portion 29f of the cam portion 29b into contact with the cam contact 38c, as shown in FIG. Also, at this time, the entire gear (not shown) is in a released state, and as shown in FIG.
a to cause interference between the stopper 41h and the cam peripheral surface 31g (in the illustrated case, they are shown separated). Please note that the end of Zenbu release does not refer to the state where Zenbu's stored power is completely released;
This refers to a state in which there is still some stored power in Zenmai even in the home position shown in Figure 7.

Then, as shown in FIG.
It is assumed that the other contact piece 44b is placed in a switchable position where it is brought close to the one contact piece 44a by the hand-operated knob 10 as indicated by a chain line.

In FIG. 4, when the full winding upper knob 32 is rotated in the direction of the arrow, the full winding upper shaft 23 rotates via the disk 31a, and the full winding upper shaft 23 (not shown) is wound up. Each time the disc 31a rotates once, the operating protrusion 31f thereof rotates in the direction of the arrow a (see FIGS. 7 and 8), thereby rotating the Geneva gear 41 by 90 degrees in the direction of the arrow. When the Geneva gear 41 rotates, the switching cam 42 integrated therewith rotates, bringing one contact piece 44a into contact with the other contact piece 44b, as shown in FIGS. 8 and 11. This means that the switch 44 is closed,
Lamp 16 lights up. When the full winding shaft 23 rotates three times, that is, the disc 31a rotates three times, the operating protrusion 31f engages with the groove 41b of the Geneva gear 41, and the stopper 41h interferes with the circumference 31g of the disc. to restrict rotation of the hoisting shaft.

When the winding of all the dances is completed, turn the winding knob 3.
When the drum 24 is released, the drum 24 is rotated by the releasing force of the wound drum 24, and a pin provided on the circumference of the drum 24 plays a specific valve on the diaphragm 21a to play a song. When the drum rotates, the support shaft 26
The integral spur gear 27 rotates the operating cam 29 in the direction of the arrow (see FIG. 13). Actuation cam 2
When 9 rotates, the cam surface for the cam contact 38c changes from its lower portion 29f to a cam surface 29c. Therefore, the main body 3 is gradually swung in the direction of arrow c in FIG. 13 as the music box plays. At this time, the lamp 16 is lit because the switch 44 is closed, as shown in FIG.

As shown in FIG. 14, when the maximum diameter portion 29e of the cam portion 29b of the operating cam engages with the cam abutment 38c, the main body 3 has rotated approximately 15 degrees from its home position. When the operating cam rotates further and its cam surface 29d comes into contact with the cam, the main body 3 begins to move back in the direction of arrow d in FIG. 14 due to the torsion spring 37 and the weight of the main body. . In this way, the main body 3 repeatedly swings in the direction of the arrow c and the direction of the arrow d until the full release force reaches its end.

When the full winding shaft 23 reaches the end of full wind release, where it rotates three times, the switching cam 42 returns to the home position shown in FIG. By fitting the contact piece, the contact piece is released from the other contact piece 44b, and the switch 44 is turned off. When the release of all the songs reaches the end, the music box movement 20 stops playing, and the main body 3 returns to the home position shown in FIG. 13 (solid line position in FIG. 1). At this time, the cam portion 29b of the operating cam is lowered by its lower portion 29f.
is brought into contact with the cam 38c. When the operating cam 29 returns to its original position, the operating cam 29 hits the cam 38 of the buffer plate provided on the support body 2 via the coil spring 40.
By coming into contact with c, the shock can be softened. Further, even if an unreasonable force is applied to the main body 3, the force is absorbed by the coil spring 40, so that this force does not directly act on the music box movement 20.

As described above, when the music box plays due to the release force of Zendan, the main body 3 swings and the lamp 16 is turned on, and at the end of Zendan release, the lamp is turned off. As shown in FIG. 11, if the manual knob 10 is left in the switch-on position, the lamp will be automatically turned on the next time the winder is wound. Of course, the lamp is turned off when the full dance reaches the end of release.

In order to operate the toy 1 without lighting the lamp, it is sufficient to leave the manual knob 10 in the switch-off position and wind up the toy as shown in FIG. When the hand control knob 10 is held in the OFF position, the music box will play and the main body 3 will swing due to the full release, and the switching cam 42 will move from one side to the other as shown in FIG. Contact piece 44
Even if you push the contact piece 44a, this contact piece 44a will not touch the other contact piece 4.
4b, the switch 44 remains off. That is, depending on whether the manual knob 10 is placed in the switch-off position (FIG. 10) or in the switch-on position (FIG. 11), the lamp 1
It is possible to select from 6 lighting modes, and it is possible to add variety to the effects of the luminous music box toy.

Next, the operation of the battery check to check the presence or absence of voltage in the power supply batteries 43a and 43b will be explained. As shown in FIG. 12, when one contact piece 44a is fitted into the cam portion 42a of the switching cam 42, that is, when the full movement is at the released end, the manual knob 10 is moved from the switch-on position shown by the solid line. When the knob is moved to the battery check position shown by the broken line, the tip 44c of the knob is attached to the protrusion 10c.
(See Figure 9)
b is bent as shown by the chain line, and one contact piece 4
Contact 4a. As shown in FIG. 9, when the switch 44 is turned on, the lamp 16 lights up if there is voltage in the batteries 43a, 43b, and does not light up if there is no voltage. When the pushing force on the manual knob 10 is released, the knob is returned to the solid line position in FIG. 12 by the elasticity of the other contact piece 44b.

(Effects of the Invention) As described above, according to the present invention in which the light-emitting section lights up and the main body swings only when the music box plays, the light-emitting music box toy becomes more interesting.
Furthermore, since the lighting of the light emitting part can be selected using a manual knob, the ways to play with the toy are expanded. Since the Zenmai winding shaft is used as the rotation center axis of the main body, the connection strength between the main body and the support body is increased, and the strength of the toy is improved. By using the full-length winding shaft, which has a large torque, as the pivot axis, the pivoting motion of the main body is ensured.
