Description

[Detailed description of the invention] The present invention relates to a doll with two faces, and in particular, the face can change suddenly by simply pressing a button.
It is about a surprising mechanism.

The purpose of the present invention is to provide a very interesting doll that will attract young children's attention at a low cost.

The present invention has a hollow body, an outer shell head, a two-sided rotating head that fits loosely into the outer shell, and a mechanism for rotating the head to change the face inside the body. The front of the head of this shell is cut out, so changes in facial features can be seen from here.

In particular, this invention is unique in that it achieves the action of rotating the head and changing its face by applying pressure on the torso, and utilizes the elasticity of the torso to return to its original face. .

Next, an embodiment of the present invention will be described using FIGS. 1 to 4. That is, the hollow body part and the outer shell head are shown in a perspective view in Figure 1, the rotating head and part of the rotating mechanism are shown in a perspective view in Figure 2, and the push button, which is another part of the rotating mechanism, is shown in an enlarged perspective view in Figure 3. Diagrams and explanations of the rotating mechanism of the doll made by combining these parts,
- A cross-sectional view is shown in FIG.

Now, the hollow body 1 is molded from synthetic resin or rubber, which has extremely high elasticity and is easily dented by pressure, and quickly returns to its original state when the pressure is released. , and an outer shell head 2 having a front notch 3 formed therein are integrally molded (FIG. 1).

A rotating head 4 is loosely fitted into the hollow outer shell head 2, and the rotating head 4 is inserted from the front notch 3.
The two doll faces 5 and 5' formed on the top can be seen alternately.

In FIG. 2, the doll face 5 is seen from direction A, and the doll face 5' is seen from direction B, and in this embodiment, the angle formed by direction AB is set to be approximately a right angle.

Note that the rotating head 4 freely rotates with 0-0 as the rotation axis. A projecting piece 9 is provided on the rotation axis 0-0 and laterally from the side surface of the rotation rod 7 formed below the rotation head 4, apart from the rotation axis 0-0.

The part of the protrusion 9 that connects to the rotating rod 7 is made thinner to form the hinge 8, and the middle part of the protrusion 9 (i.e., the part away from the rotation axis 0-0) is shown in Fig. 3. A connecting hole 10 for connecting the tip of a horizontal rod 11 extending from the push button 6 was bored.

In this figure, projections 13 and 13' formed on the upper side surface of the rotary rod 7 are shown, and as will be described later, these are related to the stopper 12 of FIG. 1, and the rotation angle of the rotary head 4 is This is to make it constant.

Now, the rotary head 4 and push button 6 are assembled into such hollow bodies 1 and 2. This rotating head 4
is supported by the necks of hollow bodies 1 and 2, and rotates from side to side. Further, this rotation angle is defined as the angle until the protrusions 13, 13' of the rotary head 4 are stopped by the stopper 12 which protrudes inward from the upper back of the body 1.

The rotating head 4 is rotated by the horizontal rod 11 connected to the protruding piece 9, that is, by the push button 6. The horizontal rod 11 is inserted into the body 1 at a predetermined position.

FIG. 4 shows how the protrusion 9 and the horizontal rod 11 are connected, that is, the motion conversion mechanism 20 is seen. . The important thing here is the direction A where you can see face 5.
However, in the initial state of the doll's movement, it is in front of the doll, so the connection between the protrusion 9 and the horizontal rod 11 is made in this way.

That is, the head 4 is rotated until the projection 13 of the rotating head 4 comes into contact with the stopper 12 on the back of the body 1. This position is the initial state A, and the projecting piece 9 is bent from the hinge 8 portion due to the connection with the horizontal rod 11. That is, the length of the horizontal rod 11 up to the connecting portion is set in this way.

It should be noted that the hinge 8 has a thin part at the base of the protrusion 9, but even if it is not particularly thin, the above condition can be achieved, for example, due to the curvature of this part. Therefore, there is no problem.

Further, the rotating rod 7 may be considered as a part of the rotating head 4, and the horizontal rod 11 does not necessarily have to be horizontal or rod-shaped. Hinge 8
It is preferable that the material is resistant to bending fatigue.

Now, how to use the doll configured in this way, whose face changes, is to grasp one part of the body, press the push button 6, and then release the pressing force.

During this time, the following operations are performed. First, pressing the push button 6 results in a linear movement of the horizontal rod 11 toward the interior of the body 1, and this is converted into a rotational movement of the rotary rod 7 by the movement conversion mechanism 20.

This rotation of the rotary rod 7 continues until the protrusion 13' reaches the stopper 12, and then stops. At this point, press button 6
I've reached the point where I can't push myself any further.

Due to this rotational movement, the other face 5' suddenly changes from the doll face 5 seen in the initial state.
It appears in the front notch 3 of the outer shell head 4,
Instead of direction A, direction B comes in front of the doll.

At this time, it can be seen that the hinge 8 portion is bent in the opposite direction from the initial state. The hinge 8 prevents excessive force from being applied to each member in the motion conversion mechanism 20. Further, the peripheral portion of the push button 6 of the body 1 is largely recessed (elastically) deformed within the body 1. At this time, the elastic repulsive force is the strongest.

By subsequently releasing the pressure on the push button 6, the body 1
The elastic repulsion force pulls the push button 6 back out, and this force is deformed and applied to the rotating head 4, causing the doll face 5' to quickly change to the doll face 5 again.

At this time, the rotational movement is such that the protrusion 13 is caused by the stopper 12
The process continues until the body 1 returns to its original shape, and this is the initial state of everything.

Incidentally, in order to strengthen the elastic force of the body 1 and increase the reverse rotation ability of the head 4, the portion of the body 1 around the push button 6 may be formed into a raised peak 19.

In this way, the rotary head 4 rotates at an angle of approximately 90 degrees with one press, and changes its face each time it is pressed (that is, each time you release your finger from the push button 6). You can play with it, and the changes are sudden, which makes it really interesting and interesting.

Now, the main ideas behind this invention are: (1) The head of the doll whose face can change has a double structure, and the inner head is rotatable relative to the outer shell head, so that it has two faces. (2) to rotate the inner head, using a motion conversion mechanism that converts the linear movement of a horizontal rod due to pressure on a part of the body into the rotational movement of a rotating rod that supports the head; (3) The reason lies in the fact that the force that returns the face of the rotating head to its original state upon release of the pressing force is dependent on the elasticity of the doll's body itself.

Therefore, it is possible to devise many detailed implementation methods and parts and their engagement to realize the present idea.

Therefore, next, I would like to explain several other embodiments for each part.

(a) First, the motion converting mechanism 20 shown in FIG.
Through this, the motion is transmitted and converted so that the rotary rod 7 is rotated back and forth within an angle of approximately 90 degrees.

Then, the head 4 rotates by the amount that the push button 6 and the protrusion 13' are pressed down until they hit the stopper 12.
The face 5 replaces the face 5′ exactly. The respective faces 5, 5' do not deviate from the front notch 3.

The next time the push button 6 returns to its original position, the elasticity of the body 1 itself is involved.

(b) Taking another example of the connecting portion between the horizontal rod 11 and the projecting piece 9, in the examples shown in FIGS. 5 and 6, the projecting piece 9 is not a hinge. Therefore, if the connection with the horizontal rod 11 is not fixed, but has some play, smoother motion conversion can be achieved.

Therefore, in FIG. 5, a horizontally long connecting hole 10' is formed in the protruding piece 9 (Figure a), and a connecting groove 14 provided at the tip of the horizontal rod 11 (Figure b) is loosely fitted into the hole.
By allowing free left and right movement, each part will not be strained when converting movement. In Fig. c, in order to form the connecting groove 14, two rising parts 15 are formed from the horizontal rod 11' with a 1 degree lower diameter, and the space between these rising parts 15 is used as the connecting groove. .

In addition, in FIG. 6, a ball 17 is provided at the tip of the protruding piece 9 (FIG. d), and a connecting groove 16 formed between the balls 17 is used to connect the horizontal rod 11 (see FIG. An example in which it is loosely fitted into the hole 18 is illustrated. Incidentally, the tip portion of this horizontal rod 11 may be made into a hinge.

(c) In addition, it is possible to perform motion conversion using any gear train, crank mechanism, etc.

(d) Also, regarding the depth of movement conversion, regarding the face of the doll, this example deals with only the case of two faces, but this may change from three to four faces.
It can also be achieved on the surface. At this time, the size of the front notch 3 of the outer shell head 2 must be adjusted. In other words, so that adjacent faces cannot be seen at the same time.

Then, taking into account the required rotation angle of the rotary head 4 when the push button 6 is pressed, the depth of pressing the push button 6 is determined to be in two or three stages, and the face obtained depending on the difference in pressing depth is selected. One way is to make it similar.

(e) Furthermore, the faces 5 and 5' formed on the rotating head 4 do not need to be the entire face, so even just a small part of the face, such as only the eyes or only the mouth, can be used. In this case, it is sufficient to form another part of the face, which does not change, on the outer shell head 2. In other words,
All the parts to be changed can be formed on the rotating head 4.

(f) For the faces 5, 5', other than molding them on the rotating head 4, adhesive stickers with the faces 5, 5' printed on them may be pasted, so there may be any number of them. The user can also select from the prepared face stickers according to their preference.

(g) It is also good to leave the face like the surface of an egg without forming a face. This is so that the user can use their arms to draw their face here. It is also interesting to combine this kind of device with the above-mentioned method.

(H) The rotary head 4 of the present invention may have a shape other than a sphere, such as a cylinder, a prism, a bell shape, etc., as long as it is approximately rotationally symmetrical. Furthermore, since there is a part that is hidden in the outer shell head 2 and is never visible from the outside, it is possible to omit (save) the original shape of this part.

(li) If a cap or the like is attached to the bottom 21 of the doll so that it can be attached or removed, the inside of the doll 1 can also be used as a container for sweets, etc.

(nu) Now, as already detailed, the body 1 is made of synthetic resin, rubber, etc. with a large elasticity, and its role is to use this elasticity to return the doll face 5' to the initial state 5. However, since all that is needed is to pull the push button 6 back to its original position, only the surrounding area of the push button 6, for example, the area around the raised peak 19, may be replaced with a strong elastic body. Since this is simply a part, many materials can be used for it.

(l) In order to further strengthen this return force, elastic force such as rubber or springs may be used to provide a force that constantly rotates the rotating head 4 in the opposite direction, or the horizontal rod 11 is constantly pressed in the opposite direction. It is also a good idea to add.

(w) Regarding this push button 6, in the above embodiment, it is exposed on the surface of the body part 1 of the doll, but even if it is joined to the inner surface of the body part 1, that is, it cannot be pressed from outside the doll. Even if the push button 6 is not visible, if this part is pressed, the above operation will be performed in the same way. The advantage of having this push button 6 inside is that the body 1 can be beautifully finished as a doll.

(W) Furthermore, this horizontal rod 11 can be integrally molded with the body 1 instead of being made into a separate part as shown in FIG. That is, if the doll is integrally molded to protrude inward from the part of the body 1 that is to be pressed, only two parts need be prepared to construct the doll.

(F) Next, the rotation angle of the rotating head 4 is defined, and the end is completed.
The projections 13, 13' on the rotary rod 7 and the stopper 12 in the body 1 do not need to be particularly formed, considering that there is a pressing limit in the body part near the push button 6.

Alternatively, it goes without saying that these may be formed in locations other than those shown in this example.

(Yo) In order to increase the effect of the phase change of this invention as a whole, it would be more interesting if a sound effect could be generated at the same time as the phase change. For this reason, it is also possible to attach any whistle to the movable part of the present invention and make the whistle sound depending on its kinetic force (for example, by combining the whistle with a bellows air pump).

Furthermore, anything that emits a beautiful tone, such as a bell, can be built-in, and it is also possible to make the human voice or music emit using an audio IC.

In this way, the present invention can be easily held and operated by infants and children, and the doll's face can change in a matter of seconds, allowing both the playmate and the doll to fully enjoy the doll's unexpected movements. In order to realize this, we have devised a very simple structure and succeeded in providing it at a low cost.
