Description

[Detailed Description of the Invention] [Industrial Application Field] In the present invention, when an egg is warmed, an oviparous animal toy comes out from inside. Regarding egg toys.

[Prior art]

Conventionally, as moving toys, pickle boxes, animal toys born from eggs, etc. are known.

A pickle box is designed so that when one person opens the lid of the box, a cat doll, monster, or other animal will pop out from inside. For this reason, it is unpredictable and interesting, and has been used frequently since ancient times.

In addition, animal toys that are born from eggs, such as ones where chicks pop out of eggs, are as interesting as the pickle box and have been popular with children for a long time.

[Problem to be solved]

However, the above toys are poor in secondary and tertiary changes over time.

That is, in the above-mentioned pickle box, after the animal jumps out of the box, the animal does not make any secondary movements.

Moreover, the animal toys born from the eggs do not undergo any secondary changes after they are born from the eggs, so it is desirable to add more variability.

The present invention has been made in view of these conventional problems, and aims to provide an egg toy, which is an oviparous animal toy, which has a relatively simple structure and is rich in variability.

[Means for solving problems]

The present invention is an egg toy comprising an egg case divided into two, an opening/closing member for opening and closing the egg case, and an oviparous animal toy built into the egg case, wherein the opening/closing member is The oviparous animal toy is configured to be openable and closable using a shape memory alloy, and its skeleton is made of a shape memory alloy, and when the egg case is heated, the shape memory alloy of the opening and closing member operates to close the egg case. The egg toy is characterized in that the egg case is opened, the egg case is opened, the egg case comes out, and the egg case is movable.

In the present invention, the egg case is an egg-shaped case made of plastic, for example, white, light brown, green, etc., and is divided into two parts.

Examples of the opening/closing member include an opening/closing tool combining a spring coil and a rod as shown in the second embodiment, or a hinge incorporating a shape memory alloy spring. These shape memory alloy spring coils and springs have a temperature above their transformation point.

Configure the egg case to open.

Examples of the above-mentioned egg-producing animal toys include a baby snake made of plastic and a cobra made of rubber.

There are monsters, penguins, chicks, etc. These have shape memory alloys built into their skeletons.

Moreover, the above-mentioned shape memory alloy may be formed into a certain shape, heat treated, and then deformed into another shape.

It is an alloy that, when heated above a certain temperature (transformation point), returns to the shape it was in when it was heat-treated before deformation. Such a metal is 1
Examples include nickel-titanium (Ni-T1) alloys and copper-zinc-aluminum (Cu-Zn-14) alloys.

The former Ni-Ti alloy has a transformation point of 10 to 90°C, and the latter Cu-Zn-Affi alloy has a transformation point of -180 to 100°C.

Therefore, the above-mentioned shape memory alloy can be used, for example, in relation to the skeleton of an oviparous animal toy, as shown in the examples.

At room temperature, it should be shaped into a curved, spiral, or coiled shape.

These elongate above the transformation temperature and allow the oviparous animal toy to move. The above-mentioned transformation point is preferably 50 to 100°C so that the above-mentioned elongation occurs when the temperature reaches 9, for example, a hair dryer or hot water in a bath.

Furthermore, the egg toy described above can also be configured as follows. In other words, an egg case divided into two parts.

a spring-equipped butterfly plate attached to one end of the divided egg case so as to be openable and closable, and a locking tool attached to the side opposite to the butterfly plate;
An egg toy comprising an oviparous animal toy built into the egg case, wherein the locking device is made of a shape memory alloy, the skeleton of the oviparous animal toy is also made of a shape memory alloy, and the oviparous animal toy is made of a shape memory alloy. When the case is heated and the shape memory alloy reaches a temperature above the transformation point, the locking device is released and the egg case opens with the spring-loaded hinge, and the oviparous animal toy comes out from the egg case. This egg toy is characterized in that the oviparous animal toy is configured to move.

A butterfly plate with a spring and a locking tool are attached between the half-cases so that they can be opened and closed (see FIGS. 5 and 6).

Moreover, a shape memory alloy is used as the above-mentioned locking tool.

For example, one side is a hook.

The other is a ring, both are hooks, etc. Also.

As mentioned above, at least one of the locking devices needs only to change its shape and be released from the locking state.The spring-loaded hinge is always biased in the direction in which the egg case opens, and the hook is When released as described above, the egg case is automatically opened.

[Action and effect]

In the egg toy according to the invention, the egg case is heated, for example, with hot air or hot water.

An opening/closing member made of shape memory alloy operates to open the egg case.

In addition, the egg case has a small rolled-up oviparous animal toy built in, so the oviparous animal toy comes out from inside the egg case, and then the oviparous animal toy is placed inside the egg case. When the shape memory alloy is heated, it elongates. Therefore, the toy oviparous animal elongates and performs a unique action. For example, as shown in the example, after lifting one animal, the body extends, and the toy oviparous animal also pops out of the egg (see Figure 3). .

In this way, the egg toy of the oviparous animal toy according to the present invention has a secondary nature that is not found in conventional toys.

Performs movements with tertiary variability.

Therefore, according to the present invention, it is possible to provide an egg toy that has a relatively simple structure and is highly variable.

Moreover, when the opening/closing member is made using a hinge with a spring and a locking tool made of a shape memory alloy as described above.

When the mass locking device reaches a temperature above the transformation point, its engagement is released and the egg case is opened by the spring force of the hinge, and the oviparous animal toy sticks out its head and moves further as described above.
