BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a movable sound toy having an action part (movable part).

[0002]

2. Description of the Related Art A toy in which a movable part is added to a sounding toy such as a music box and the movable part is operated by a driving source such as a full-bodied or motor has already been proposed. For example, as shown in FIG. 33, a music box movement is incorporated in a case simulating a house having a window, and movable parts A and
The sliding doors A and B are urged by a coil spring C in a direction to close the sliding doors A and B, and the cam contact portions Ab and Bb of the arms Aa and Ba extended from the sliding doors are brought into contact with the cam D. It is configured to make contact. The cam D is driven to rotate by an output shaft E that is driven by a music box movement (not shown). In the cam position shown in the figure, the sliding doors A and B are open, and when the cam rotates from this position, the cam contact portions Ab and B are accordingly moved.
When b approaches each other, the sliding doors A and B are moved in the closing direction by the elastic force of the coil spring C.

The movable part in the example shown in FIG. 33 is a sliding door which reciprocates and opens and closes a window, but there is also one in which a swinging part is driven by a cam. Further, among sound-generating toys using a motor as a drive source, there has been proposed a toy that operates a movable component by a driving force of the motor.

[0004]

In the case of the example shown in FIG. 33, the opening and closing strokes of the sliding doors A and B are one-to-one with the stroke of the cam D. Therefore, if the moving amount of the sliding doors A and B is to be increased. Also, the cam D has to be enlarged accordingly, and there is a problem that the structure becomes bulky.
If the stroke of a movable part such as a sliding door is increased, a large rotational torque is required for the cam D, so that a drive source that generates high torque is required. In particular, in the case of using a music box full dance as a drive source, the limit of the obtained torque is small. Further, there is a problem in terms of component strength that the movable component and the cam need to be disposed as close as possible to each other in order to obtain smooth operation of each other. Further, since the cam and the movable part are directly operated,
If an action such as holding down a movable part with a hand is added to prevent the movement, injury or malfunction of the part due to deformation or damage may occur, resulting in insufficient safety and functional security. There is a problem.

Therefore, an object of the present invention is to provide a large working stroke even with a small rotational torque, to smoothly move even if the distance between the movable part and the cam is large, and to satisfy the safety rules and prevent misuse. It is an object of the present invention to provide a movable sound toy capable of avoiding damage to parts.

[0006]

[0007]

When the sounding body is actuated and sounded by a driving source such as a full dance, the cam rotated by the driving source swings the short piece of the transmission lever to reciprocate the figurative member with the long piece. When the movement of the figurative member from the outside of the toy is prevented, the transmission lever driven by the cam rotates independently of the figurative member and separates the transmission of the driving force between the figurative member and the cam. Operate. Since the long side of the transmission lever is engaged with the figurative member, the length from the fulcrum to the figurative member is longer than when the figurative member is engaged on the short side, and the buffering action of the transmission lever, that is, In addition, when a load is applied to the transmission lever, the allowable deformation amount until the transmission lever is damaged is increased. In addition, since the long piece of the transmission lever is formed of a material that can be elastically deformed, the allowable deformation amount until the transmission lever is damaged is further increased.

As shown in FIG. 18, a hanging string 29
(See FIG. 9).

A front case 10A and a rear case 10B, each housing and mounting various figure members and a mechanism for driving them.
After being superimposed on each other, the lower part of the case is fixed via the front panel 10C. As for the upper part of the case, the fitting part 10Da of the front roof 10D passes through the through hole 10w of the front case 10A, and the fitting part 10Ea of the rear roof 10E passes through the through hole 20w of the rear case 10B and fits into the fitting part 10Da. After that, as shown in FIG. 9, the fixing screws 28 with the rear roof 10E
Is screwed into the fitting portion 10Da and fixed.

The operation of the embodiment configured as described above will be described. First, the position of each figurative member in a state where the accumulating force of the whole dance is released, that is, the home position (stop of the music box) will be described. When the accumulating force of the whole dance is weakened, the animal cam 21b is provided with the cam follower 27c of the animal transmission lever 27 at the concave portion 21bb or the upwardly inclined portion from the concave portion to the convex portion 21ba as shown in FIG. Stop at the position where is engaged.

At the stop position of this cam, the animal 1
2 is stopped at a position where the engagement piece 12 is engaged with the transmission lever 27, and the cam follower 24a of the transmission lever 24 for the bear is engaged with the base surface 21aa of the cam 21d for the bear (see FIG. 12). By doing so, as shown in FIG.
The bear 4 is retracted inside the bear storage section 13b.

On the other hand, when the cam 21a for the sliding door is engaged with the cam follower 19e of the intermediate lever 19 in the closed position holding portion 21aa (see FIG. 11), the transmission lever 1 is turned on.
The sliding doors 5 and 16 are located at the sliding door closing position (see FIG. 3) due to their respective rotating habits.

When the whole dance winding knob 23 (see FIG. 7) is rotated to wind up the full dance 22d of the music box movement 22 (see FIG. 8), the drum 22e is moved by the governor mechanism 22f by the releasing force of this. The speed is adjusted and the rotation is performed at a constant speed, and the tune is played by playing the diaphragm 22h. Drum 22
The output shaft 22a rotates simultaneously with the rotation of e to rotate the cam 21.

When the cam 21 rotates, each of the shape members operates in accordance with the rotation of each cam portion. Therefore, each of the shape members will be described below. When the music box movement 22 sounds and the sliding door cam 21a rotates, this cam causes the cam follower 19e engaged with the closed position holding portion 21aa to engage with the opening portion 21ac, thereby causing the mediating lever 19 to move to the cylindrical shaft portion 20c. 5 (see FIG. 7) is rotated clockwise in FIG. The rotating mediating lever 19 has its engaging portion 1
9b and 19c push up the engaging ends 15h and 16h of the short pieces of the transmission levers 15 and 16 and push these levers against the elasticity of the respective torsion coil springs 17 and 18 around the support shafts 10e and 10n. Long pieces 15b, 16b
Are rotated in a direction away from each other.

When the transmission levers 15 and 16 rotate, the sliding doors 2 and 3 which are engaged with the long holes 15a and 16a of the long pieces by the pins 2d and 3d respectively move the windows 10a and the upper edge of the guide plate 13. 10aa, 13c and lower edge 10ab, 1
It is guided at 3d (see FIG. 6) and is moved at a relatively slow speed in a direction to open each other. Cam Follower 1
When 9e comes into contact with the open position holding portion 21ab of the sliding door cam 21a, the transmission levers 15 and 16 are rotated to the maximum, and as shown in FIG.
3 is opened to the maximum and moved to a position sufficient for the bear 4 to advance. This open position is maintained until the cam follower 19e comes off the open position holding portion 21ab of the cam 21a.

Then, the cam follower 19e of the intermediate lever
Engages with the closing portion 21ad formed by the steep slope of the cam 21a, the intermediate lever 19 causes the torsion coil spring 17,
Under the resilience of No. 18, it descends and swings at a rapid speed toward the closed position holding portion 21aa. When the cam follower moves rapidly, the transmission levers 15 and 16 are resilient by the torsion coil springs 17 and 18 so that the long pieces 15b and 16
Then, the sliding doors 2 and 3 are rotated in a direction in which the sliding doors 2 and 3 are rapidly closed. FIG.
The closing position of the sliding doors 2 and 3 shown in FIG.
Is maintained until the cam is separated from the cam closed position holding portion 21aa. The opening / closing operation of the sliding doors 2 and 3 is performed by the cam 2
This is repeated until the rotation of one rotation, that is, the release force of the whole dance as a driving source of the music box movement 22 is lost.

Now, as shown in FIG. 5, when the opened sliding doors 2 and 3 are moved in the closing direction, for example, the sliding doors 2 and 3 are closed with a fingertip so as not to hinder the movement. If the finger is pinched in Step 3, the sliding door is stopped at that position. For example, when the sliding door 2 moving in the closing direction is pressed with a finger, the transmission lever 15 is moved.
Is prevented from rotating. At this time, the other sliding door 3
The closing behavior by the torsion coil spring 18 is acting,
The transmission lever 16 rotates independently of the transmission lever 15 with the swing of the mediation lever 19, and moves the sliding door 3 that is not pressed in the closing direction.

In other words, even if the finger is pinched between the movable members (2, 3), the transmission of the driving force between the cam for driving the movable member and the movable member is interrupted, so that no injury is caused and the safety is maintained. is there. When the finger is released from the sliding door 2, the sliding door 2 is urged by the torsion coil spring 17 and moves according to the transmission lever 15 that rotates to a position where the sliding door 2 engages with the intermediate lever 19.

When the cam 21 is rotated and the sliding doors 2 and 3 are held in the fully opened position, the cam 21 for the bear
d is the cam projection 21db as shown in FIG.
To swing the transmission lever 24 for bear. Cam projection 21d
b, the transmission lever 24 is pressed against the screw 4f to push the bare 4 from the bare storage 13b into the window 1.
Extrude to 0a. The bear 4 that has advanced to the window is located at a position before the sliding door 3 (see FIG. 9). Cam 21d
As the rotation proceeds, the bear 4 urged by the coil spring 4e retreats from the window 10a toward the bear accommodating portion 13b according to the transmission lever 24 that swings and returns with the cam projection 21db. When the bear 4 retreats, the sliding doors 2 and 3 are moved in the closing direction.

By the way, as shown in FIG. 4 (a), when the bear 4 placed at the projecting position or the bear 4 moving toward the projecting position is pushed into the inside of the bear accommodating portion 13b, the bear 4 becomes It can be moved without any difficulty. That is,
When the bear 4 is pushed in the above state, the cam follower 2 of the second lever 24B of the bear transmission lever 24 is pushed.
4a is engaged with the cam projection 21db and its movement is regulated, but the first lever 24A is
Against the elasticity of C, a clockwise direction about the shaft portion 24Aa independently of the second lever 24B (in FIG. 4A)
To absorb the pushing movement of the bear 4.

When the pushing operation on the bear 4 is stopped, the bear 4 moves to a position corresponding to the swing position of the transmission lever 24 and stops. Therefore, even if the bear 4 is inadvertently or intentionally pushed in or its protrusion is prevented, the drive system and the shape member are not damaged by the one-way transmission action of the transmission lever 24.

When the animal cam 21b rotates, the animal transmission lever 27 rotates to move the animals 11 and 12 up and down. As shown in FIG.
When the cam follower 27c is engaged with the concave portion 21bb of the cam 21b, the engaging portion 27a of the transmission lever 27 is engaged with the engaging piece 12d to push up the animal 12 as shown by a chain line 12A in FIG. . The animal 11 connected to the animal 12 by the swing lever 25 is lowered as shown by a chain line 11A in FIG.

When the transmission lever 27 swings with the rotation of the cam 21b and engages the cam follower 27c with the projection 21ba, as shown in FIG. 4A, the engagement portion 27a of the lever is Can be lowered. When the engaging portion 27a is lowered, the swing lever 25 swings around the pin 10u due to the weight of the animal 12, the animal 12 is lowered and the animal 11 is raised (see the solid line position in FIG. 3 and FIG. 10). Hereinafter, the animal 11 and the animal 12 are
Ascending and descending are alternately repeated with the rotation of b. The operation when the movement of the animals 11 and 12 moving up and down is prevented will be described. As shown in FIGS. 4 and 10, when the animal 12 is lowered and a finger is put on the animal 12 to prevent the animal 12 from rising, the engaging piece 12d of the animal 12 is moved to its position (see FIG. 4A). Is held.
On the other hand, the animal cam 21b which continues to rotate is shown in FIG.
The animal drive lever 27 rotates from the position (a) to the position shown in FIG. 2B, but since the movement of the engagement piece 12d is prevented, the animal drive lever 27 only flexes the spring 27e. Therefore, the swinging operation is limited to the upper limit of the engagement piece 12d. This operation is the same when the movement of the animal 11 is prevented. Therefore, even if the movement of the animals 11 and 12 is hindered from the outside, the mechanism for driving them is not damaged.

As described above, the cam 21 which rotates with the sound of the music box movement 22 as a sounding body driven by the whole dance 22d as a driving source, as shown in FIG. , 16 (in the illustrated embodiment, via the intermediate lever 24), the sliding doors 2, 3 are reciprocated in the X direction, the bear 4 is moved in the Z direction by the transmission lever 24 by the bear cam 21d, and the animal is moved by the animal cam 21d. 11 and 12 are reciprocated in the Y direction.

Particularly, since the sliding door cam 21a is an end surface cam whose cam surface changes in the axial direction of the output shaft 22a, the loss of the rotating torque of the music box movement is small. In other words, since the music box movement has a large torque, it is small. A stable driving force can be obtained with the driving source. This is advantageous for driving the figure member arranged at a position relatively far from the drive source by increasing the lever ratio.

In the illustrated embodiment, a pair of sliding doors 2 and 3 which are opened and closed in the left-right direction are mentioned, but a bearer 4 moving in the front-rear direction is one of them. Further, the shape member that moves up and down may be a member that moves up and down.

In the illustrated embodiment, the sounding body is a music box toy of the whole dance type, but the sounding body is a sounding toy having a driving source such as an onomatopoeia toy, a record sounding toy, a tape sounding toy, or the like. Can also be applied. The drive source for rotating the cam is not limited to a full-bodied drive, but may be a motor.

Further, in the illustrated embodiment, the guide plate 13 is provided on the front case 10A and supported so as to guide the sliding doors 2 and 3 that open and close to the left and right and the bear 4 that moves forward and backward, so that the mounting dimensions are large. Good accuracy and assembly workability.

[0066]

As described above, according to the present invention, the transmission lever having the long piece and the short piece is arranged between the cam and the figurative member so that even if the distance between the cam and the movable part is large, Since the small displacement of the cam is transmitted to the figurative member by using the lever ratio, it is possible to obtain a movable sounding toy having a figurative member capable of obtaining a large operation without increasing the bulk of the toy. Since one long side of each transmission lever is engaged with the first and second figurative members, the distance from the fulcrum to each of the figurative members is smaller than when each figurative member is engaged on the short side. length longer, buffering action of the transmission levers, i.e., first
In addition , when a load is applied to the second transmission lever, the allowable deformation amount up to breakage increases. When the long side of the second transmission lever is formed of a material capable of elastic deformation, the deformation allowance to failure of the transmission lever is further increased,
An action to prevent the movement of the second shape member is added,
