Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention uses a shape memory alloy. Concerns toys for animals such as snakes and chameleons that swallow food from small animals such as insects and frogs.

[Prior art]

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

The pickle box is designed so that when two people open the box with their hands, animals such as cat dolls and monsters pop out from inside. For this reason, it is unpredictable and interesting, and has been widely used 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 above-mentioned Binkuri box, and have been popular with children for a long time.

[Problem to be solved]

However, the above toys are secondary and tertiary.

There is little change 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.

Further, 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 it is an object of the present invention to provide an animal toy that swallows food and has a relatively simple structure and is highly variable.

[Means for solving problems]

The first invention of the present application is an animal toy such as a snake that swallows a small animal such as a frog, and which includes a bias spring biased in the direction of extension along the longitudinal direction of the body of the animal, and a shape memory alloy made of a shape memory alloy. A spring device consisting of an elastic body is provided, and a rod-shaped body having a small animal such as a frog at the tip is connected to the spring device,
Further, the mouth of an animal such as a snake is provided with an opening/closing device made of a shape memory alloy that opens when heated, so that the animal such as a snake opens its mouth and then swallows the food of the small animal. There are animal toys that can be swallowed.

In the present invention, the most noteworthy feature is that a spring device consisting of a bias spring biased in the extension direction along the longitudinal direction of the animal toy and an elastic body made of a shape memory alloy is provided;
This spring device is connected to a rod-shaped body with bait for small animals such as insects and frogs at its tip, and an opening/closing device made of a shape memory alloy is provided in the mouth of a snake or the like.

Thus, when a toy is heated, a snake or the like opens its mouth by means of an opening/closing device, and then the expandable body expands or contracts to swallow food from a small animal or the like.

In addition, the above-mentioned shape memory alloy means that even if it is deformed into a different shape after being formed into a certain shape and heat-treated, if it is heated above a certain temperature (transformation point), it will return to the shape it was in when it was heat-treated before deformation. It is an alloy. Examples of such metals include 1, for example nickel.
Titanium (Ni-Ti) alloy, copper, zinc, aluminum (
There is a Cu-Zn-A2) alloy.

The former Ni-Ti alloy has a transformation point of 10 to 90°C.
And the latter Cu-Zn-Aj! The transformation point of the alloy is -180 to 100°C.

However, for example, as shown in the embodiment, the shape memory alloy is used in a spiral or coiled shape at room temperature for a spring in an animal toy.

These elongate at temperatures above the transformation point, allowing the rod-shaped body corresponding to the tongue of the animal toy to move. The above transformation point is 1 - 50 - so that elongation occurs due to temperature changes such as hot water in a hair dryer bath, electric heating of batteries, etc.
It is preferable to choose 100°C.

The rod-shaped body may be a wire, an elongated rod-shaped body, etc. 2 For example, shape memory alloy cotton, W4&II, or nichrome wire can be used. In addition, the spring device includes a bias spring that is biased in the direction of extension along the longitudinal direction within the body of the animal, and an elastic body made of a shape memory alloy.
You can use a combination of rods (
(See Figures 3, 1, 4, 7 and 8').

Thus, the bias bus biases the rod-shaped body in a direction to push it forward from the mouth.

Further, the extensible body is used to expand or contract when heated to draw the rod-like body into the mouth.

The animals mentioned above include snakes, chameleons, and dinosaurs.

There are long-eared fish, etc. In addition, small animals include insects, frogs,
There are small fish etc.

The above-mentioned opening/closing device may be constructed of a coil spring made of a shape memory alloy, a U-shaped or V-shaped jaw skeleton body, etc.
Figures 1, 2, 5, and 6.

(Refer to the first embodiment and the second embodiment).

Further, in the first invention, the animal pulls a frog or the like into its mouth, but as shown in the second invention below,
On the contrary, it is also possible to make animals jump on frogs and the like.

That is, the second invention is an animal toy such as a snake that jumps on a small animal such as a frog and swallows the small animal.

A stretchable body made of a shape memory alloy is provided inside the body of the animal along its longitudinal direction, and a rod-shaped body with a small animal such as a frog attached to the tip is connected to the body of the animal. The mouth of the animal is provided with an opening/closing device made of a shape memory alloy that opens when heated, and the animal such as a snake opens its mouth when heated, and then the animal jumps at the small animal and swallows the food. It is found in animal toys that swallow food.

Also in the second invention, the contents of the constituent elements are the same as in the first invention.

[Action and effect]

In the animal toy according to the first aspect of the present invention, when an animal such as a snake is heated, for example, with warm air or hot water, the opening/closing device using the shape memory alloy is activated and the mouth of the snake or the like opens.

Moreover, a spring device consisting of a bias spring biased in the extension direction along its longitudinal direction and an expandable body made of a shape memory alloy is built into the body of the snake. Therefore,
The expandable body expands or contracts when heated and draws a rod-like body corresponding to a tongue from within the body, thereby performing the characteristic behavior of the above-mentioned animal swallowing a small animal such as a frog.

On the other hand, when the shape memory alloy cools and becomes soft, the small animal such as a frog is pulled out of the snake's mouth again by hand, and the mouth is then closed. The above operations are then repeated, allowing you to play the game over and over again.

Further, in the second aspect of the present invention, the expandable body expands forward when heated, stretches the torso forward, and performs the characteristic action of the animal jumping on and swallowing a small animal such as a frog.

In this way, the animal toys according to the first and second inventions are secondary toys that are not found in conventional animal toys.

Performs movements with tertiary variability.

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

〔Example〕

First Embodiment A toy according to an embodiment of the first invention will be described with reference to FIGS. 1 to 4.

That is, the toys of the five examples are as shown in FIGS. 1 and 2.
A bias spring 2 is biased in the direction of extension along its longitudinal direction within the body of the snake.

A spring device A consisting of an elastic body 3 made of a shape memory alloy is provided,
Also, a movable plate 42 between the bias spring 2 and the elastic body 3
A rod-shaped body 5 with a small animal 8 such as a frog attached to the tip is connected to the rod-shaped body 5.

Further, the snake's mouth 10 is provided with an opening/closing tool 6 made of a shape memory alloy that opens when heated, and is configured to open the snake's mouth 10 by heating and then swallow the small animal 8 such as the frog.

The body l of the snake toy is made of plastic and an elastic material such as rubber.

Further, the bias spring 2 is made of a spiral elastic body. Further, the elastic body 3 is made of nickel titanium (Nl
-Constructed from a spiral elastic body made of an alloy. In addition, the alloy has a transformation point in the range of 38 to 42 degrees Celsius, which is the temperature of bath water, and as shown in Figure 4, its shape is memorized in advance so that it stretches to a certain length in this temperature range. ing.

Further, the bias spring 2 is inserted into the rear side of the case 4 of the spring device A, as shown in FIG.

The case 4 is fixed in the body 1 at both ends by locking plates 41 and 43. Further, the expandable body 3 is also inserted into the front side of the case 4. In the case 4, a movable plate 42 is provided between the bias spring 2 and the elastic body.

Further, a rod 40 is fitted into the center of the axis of the bias spring 2, and one end of the rod 40 is loosely inserted into the locking plate 41.

Further, a small animal 8 such as a frog is placed at the tip of the rod-shaped body 5. The rod-shaped body is loosely inserted into the locking plates 4 and 3.

Moreover, the locking plate 43 is.

It is fixed in the fuselage 1 by a locking tool 45.

Further, the opening/closing tool 6 provided in the opening 10 is made of nickel.
It is constructed from a V-shaped elastic body made of titanium alloy. The opening/closing tool 6 is installed inside the two jaws as shown in FIG. Further, the transformation point of the alloy is 35 to 40°C, which is slightly lower than that of the elastic body 3.

Further, the rod-shaped body 5 is made of a copper wire with good thermal conductivity so that heat from outside the body can be quickly transferred to the expandable body 3. A small animal 8 such as a frog made of plastic is attached to the tip of the rod-shaped body 5.

Next, each action and effect will be explained.

In the snake toy of this example, at room temperature, the elastic body 3 contracts and the bias spring 2 extends in the longitudinal direction, as shown in FIG.

By warming the above-mentioned snake toy 2 with warm water in a bath, for example, the opening/closing tool 6 at the square opening 10 is heated as shown in FIG.
expands and the angle of the figure 7 opens, which creates the snake's mouth 1.
0th order where 0 opens in the F direction.

The elastic body 3 of the spring device A in the body 1 is heated to a transformation point by hot water. Therefore, the expandable body 3 resists the urging force of the bias spring 2 and expands in the direction of the arrow. As a result, as shown in FIG. 4, the rod-shaped body 5 is pulled, and the toy snake swallows a small animal 8 such as a frog with its mouth 10 open.
In this way, the eight toy snakes exhibit the characteristic behavior of a snake swallowing a small animal 8 such as a frog.

On the other hand, when the extensible body 3 and the opening/closing tool 6 cool and become soft, as shown in FIG. 3, a small animal 8 such as a frog, such as a frog, is pulled out by hand from the snake's mouth IO again, and the mouth IO is closed in the direction C. As a result, the elastic body 3 contracts due to cooling, and the bias spring 2 returns to its extended state along the longitudinal direction due to its biasing force. Then, you can play by repeating the above actions many times.

As described above, the snake toy in this example exhibits movements with secondary and tertiary variability that are not seen in conventional moving toys.

Therefore, according to this example, it is possible to obtain an animal toy that swallows food and has a relatively simple structure and is highly variable.

Second Embodiment This example uses a bias spring and an elastic body as shown in FIGS. This uses a spring device B whose position is reversed, and a U-shaped opening/closing device 7.

That is, one example of a snake toy includes a bias spring 21 and an elastic member 3.
1, a small animal 8 such as a frog provided at one end of a rod-shaped body 5, and a U-shaped opening/closing device 7 provided in the jaw of a snake's mouth 10. The opening/closing tool 7 is made of a shape memory alloy of nickel-titanium alloy having a transformation point of 35 to 40 DEG C., similar to the opening/closing tool 6 in the first embodiment. The other configurations were the same as those of the first embodiment.

However, the snake toy in this example is not stable at room temperature.

As shown in FIG. 7, the expandable body 31 made of shape memory alloy is in an expanded state. Therefore, the bias spring 21 is in a contracted state.

Next, by warming the snake toy with warm water.

As shown in FIG. 8, the opening/closing tool 7 first extends and the snake's mouth 10 opens in the P direction.Next, when the elastic body 31 is heated to a transformation point, it contracts in the C direction.

Then, the bias spring 21 expands, the rod-shaped body 5 is pulled, and the toy snake swallows a small animal 8 such as a frog with its mouth 10 open. Furthermore, after the elastic body 31 and the opening/closing body 7 are cooled, By the same operation as in the first embodiment, the original state is restored as shown in FIG.

Therefore, according to this example, like the first example above,
It is possible to obtain an animal toy that swallows a wide variety of food with a relatively simple structure.

Third Embodiment A snake toy according to the second invention will be explained using FIG. 2 and FIG. 1O.

That is, in the snake toy of this example, compared to the first example, the snake jumps forward and swallows the food.

In other words, the case 4 containing the two expandable bodies 3 is fixed to the body 1 at the rear by a fixing member Q46, and also at the front near the mouth 10 by a fixing member 47. Further, the front half of the body 1 on the outer periphery of the elastic body 3 is constituted by a bellows-shaped elastic body 11. The expandable body 3 is made of a shape memory alloy that expands when heated.

Further, the rod-shaped body 10 having a small animal 8 such as a frog at its tip is fixed at its base end to the fixture 46 . The rest is the same as the first embodiment.

As shown in FIG.
is opened in the F direction.Then, the expandable body 3 expands in the L direction.

As a result, the bellows-shaped elastic body 11 also extends in the F direction. Then, the toy snake jumps forward and swallows the small animal 8 that is the food.

Therefore, according to this example, with a relatively simple structure,
You can get a highly variable snake toy that jumps on food and swallows it.
