Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a music box toy in which the limbs and wings of characters such as animals, birds, and insects are moved by a music box.

[Prior art]

In conventional music box toys, the action of, for example, the limbs of a character animal, or the wings of a bird or insect, is moved up and down by a cam fixed to the output shaft of the music box, such as the lever 27 shown in FIG. 6, and this lever 27 is lowered. When the lever 27 is raised, the limbs 28 are rotated and the outer sides are raised, and when the lever 27 is raised, the limbs 28 are configured to descend by their own weight.As the output torque of the music box is limited, the movement of the limbs is not limited. I can't do it quickly, my speed is slow,
Furthermore, since the movement was limited in scope, it did not attract the viewer's interest, and it lacked interest and enjoyment.

[Purpose of invention]

In view of the above-mentioned drawbacks, the present invention proposes a music box toy that arouses the interest of the viewer by making the limbs of animals, wings of birds and insects move quickly and vibrate in a simple manner in time with the sound of the music box. That's true.

[Structure of the idea]

The present invention provides a movable plate that is moved by a music box inside the doll case, and this movable plate has a cam surface with continuous small concave and convex teeth, and a movable member that can come into contact with this cam surface is rotated around the case. The movable member is movably supported, and a part of the movable member is made to protrude outside the case, and the entire movable member is always biased toward the cam surface side and at a neutral position in the rotation area via a spring member. is caused to follow the movement of the cam surface of the movable plate and to cause a slight vibration movement.

〔Example〕

The present invention will be explained below with reference to an embodiment shown in the drawings. In Figures 1 and 2, the music box toy is in case 1 on the front side.
A movable plate 3, a slide plate 4, and a music box 5 are housed in a doll case formed by a case 2 on the rear side, and a lever 7 is rotated by a cam plate 6 fixed to a drum shaft 10 of the music box 5. Movable plate 3 at 7
is moved up and down, the movable member 8 protruding from both sides of the cases 1 and 2 is moved slightly vibrating, and the movable plate 3 slides the slide plate 4 left and right to move the case 1 and 2.
A rocking plate 9 protruding from the upper side is rocked left and right.

The movable plate 3 is provided with long holes 3a as shown in FIGS. 1 and 2, so that the two pillars 1a of the front case 1
is inserted and placed on the rib 1b, mounted so as to be movable up and down with a screw 11 and washer 12, and urged downward by a spring 13, and a cam having continuous relatively shallow concave and convex teeth on both sides of the long hole 3a A surface 3b is formed and the protrusion 8a of the moving member 8 comes into contact with the moving member 8, and the moving members 8, 8 are urged by a spring member 14 to the cam surface side and a neutral position in the rotation area. A notch 3c is provided on the upper side of the movable plate 3, and one end 7a of the lever 7 comes into contact with the cutout 3c, and a pin 3d is formed on the upper side and is inserted into the inclined elongated hole 4a of the slide plate 4.

The slide plate 4 has elongated holes 4b bored in two places, into which the struts 1c of the case 1 are inserted, and is mounted on the ribs 1d so as to be slidable left and right with screws 15 and washers 16. The front side 4c has a pupil drawn thereon, and faces the through hole 1e of the case 1 as shown in FIG. A pin 4d is formed on the upper side of the slide plate 4, and the swing plate 9
A dead point spring 17 is attached between the pin 9a and the pin 9a. The rocking plate 9 is connected to the pin 1 of the case 1.
The case 2 is held swingably by the pin 1f, and a pin 1f is inserted into the hole 2a of the case 2 to prevent it from coming off, as shown in FIGS. 4 and 5.

The moving member 8 is formed in the shape of a wing and is rotatably held by a pin 1g of the case 1, and the pin 1g is inserted into the hole 2b of the case 2 to prevent it from coming off as shown in FIGS. 4 and 5. , protrudes outward from the notch 1h of the case 1 and the notch 2c of the case 2.
It is desirable that the weight balance of the moving members 8 on both sides be the same.

The cases 1 and 2 are joined together by screws 18 screwed into the screw holes of four pillars 1i formed in the case 1 from the case 2 side, as shown in FIGS. 1 and 5.

As shown in FIGS. 4 and 5, the music box 5 is fixed to the case 2, and a pulley 21 with a string 20 wound around the entire dance shaft 19 is screwed together, and the pulley 21 is housed in the cylindrical portion 2d of the case 2. ing. The music box 5 has a barrel 23 and a diaphragm 24 on a frame 22.
is fixed and a speed governor (not shown) is installed inside the barrel, and when the drum 25 is fixed to the drum shaft 10 which is pivotally supported on the frame 22 and the drum 25 is rotated, the cam When the plate 6 is rotated, the lever 7 is rotated by the concave 6a and convex 6b of the cam plate 6.

The lever 7 has a bearing plate 2 on the back side of the frame 22.
A shaft portion 7b is rotatably supported at 6, and a protrusion 7c at the other end faces the cam plate 6. The shaft portion 7b may be rotatably inserted into the frame 22 by providing a bearing support in the case 2.

The operation of the music box toy is as follows: when the string 20 is pulled down, the pulley 21 is rotated to wind up the whole dance, the drum 25 is rotated, the diaphragm 24 is played by the pin of the drum, the music box 5 is played, and the cam When the plate 6 is rotated, the lever 7 is rotated, and the protrusion 7c falls into the recess 6a as shown by the solid line in FIG. When the protrusion 7c is pushed up by the protrusion 6b, the movable plate 3 is moved upward at one end 7a.

With this downward movement of the movable plate 3, the movable member 8, which is urged to the neutral position by the spring member 14, moves from the neutral position every time the protrusion 8a engaged with the uneven teeth of the cam surface 3b of the movable plate 3 crosses one peak. The movable plate 3 is moved upward and downward.
When the movement member 8 is moved up and down, it is moved vertically downward from the neutral position, and since the moving member 8 protrudes more out of the case than into the case, it is moved up and down with a large amplitude and vibrates slightly, and the slide plate 4 is also moved up and down with a large amplitude. As it is slid from side to side, the black eye appears in and out of the through hole 1e, resulting in a jerky movement, and the rocking plate 9
is swung left and right by the det point spring 17, making it possible to create a music box toy that arouses the interest of the viewer.

When the music box toy is configured as described above,
The movable plate 3 is moved up and down six times in one rotation of the drum 25, and the movable member 8 can be made to vibrate slightly by the number of uneven teeth on the cam surface 3b with one up and down movement of the movable plate 3. It allows for quick movements like flapping wings without the need for large torque. Further, the protrusion 8a of the moving member 8 and the cam surface 3b are shallowly engaged and biased to the neutral position by the spring member 14, so even if a child rotates the moving member 8, the engagement can be easily released and the mechanism will not be damaged. The same applies to the swing plate 9.

The pitch of the unevenness of the cam surface 3b where the small uneven teeth are continuous is set as appropriate, and may be replaced with a plurality of pins or the like.

In the above description, six sets of protrusions and recesses are formed on the cam plate 6, but if the number of sets is increased, the micro-vibration movement of the moving member 8 becomes more intense, so the number of sets is appropriately set. The rising and falling speeds of the movable plate 3 may be changed by changing the shape of the cam plate 6.

The shape of the movement member 8 may be formed into other shapes such as limbs other than wings.

In the above description, one spring member 14 is used to urge the movement members 8 on both sides to the neutral position, but two spring members may be used to independently urge each movement member to the neutral position, or springs of other shapes may be used. You may use the member.

[Effects of the invention] Since the invention is constructed as described above, it has a simple construction and allows the wings, limbs, etc. of characters imitating animals, birds, insects, etc. to move quickly and to move in conjunction with the sound of a music box. It is possible to provide a music box toy that has excellent practical effects, such as being able to make a flapping-like micro-vibration motion to create an action that arouses the interest of the viewer.
