Problems to be Solved by Conventional Technology and Invention Conventionally, a traveling toy in which a vehicle body set on a chassis is detachable is disclosed in Japanese Utility Model Laid-Open No. 59-184897. With the running toy, the shock between the chassis and the vehicle body is released by the impact, and the enjoyment of the action of detaching the vehicle body can be enjoyed.

The present invention provides a plurality of detachable car bodies for the chassis, and you can enjoy by transforming into a variety of running toys with different appearance shapes with a single chassis, and by changing the colors, patterns etc. when mounting the car body It is intended to provide a traveling toy having improved toy properties and commercial properties.

Means for Solving the Problems The present invention will be described with reference to the drawings.

The traveling toy 1 of the present invention comprises a chassis 2 and a vehicle body 3 which is detachably mounted on the chassis 2. At least a part of the chassis 2 which faces the vehicle body 3 to be mounted is 30-65.
An energization heat generation layer 21 that generates heat at ℃ is provided, and a reversible thermochromic layer 31 that discolors at the heat generation temperature of the energization heat generation layer 21 is disposed in the vehicle body 3 at a position in contact with or close to the electricity generation heat generation layer 21. It is required to be installed.

In the above description, the chassis 2 has a conventional structure (for example, not only a self-propelled type that is driven by a mainspring or a motor but also a simple structure that is driven by an external force) to rotate and rotate the shaft-supported wheels. All are valid.

The energization heat generation layer 21 may be a linear or planar heat generation layer formed using a conventionally known energization heat generation material, an electricity generation heat paint, or the like, and the heat generation temperature can be controlled in the temperature range of 35 to 55 ° C. , "ON-OFF switch" and automatic temperature control mechanism can be installed as appropriate to prevent danger due to overheating.

It is desirable in terms of safety of the toy to connect a low-voltage power source to the energizing heat generating layer 21 to energize it, and more effectively, to connect the energizing heat generating layer 21 in series to generate heat, a battery or A dry battery or the like can be replaced and arranged.

The reversible thermochromic layer 31 is a layer that reversibly discolors in the temperature range, and a conventionally known reversible thermochromic material, for example, an electron-donating color-developing organic compound, an electron-accepting compound and the two A material consisting of a homogeneous compatible solution containing a discoloration temperature controlling agent that determines the occurrence temperature of a color reaction as an essential component is effective, and is proposed by the applicant of the present invention, Japanese Patent Publication Nos. 51-44706 and 51-447.
The thermochromic material disclosed in 08, Japanese Examined Patent Publication No. 1-11656, JP-A-60-264285, etc. can be used and applied as a coloring material such as printing ink or paint to form various images, or The image and the non-color-changing image with the non-color-changing ink can be overprinted to further diversify the change.

The thermochromic layer 31 may be formed directly on the surface of the vehicle body 3, or may be formed by pasting a sheet material such as paper or a film, which is formed in advance. Alternatively, the thermochromic material may be melt-blended with a thermoplastic material to form a film, and the film may be concealed and arranged on a non-color-change image printed on the vehicle body surface.

The thermochromic layer 31 can be formed not only on the inner surface of the vehicle body 3 (contact surface side with the chassis 2) but also on the outer surface of the thin and opaque vehicle body 3.

Although the material of the vehicle body 3 is not specified, a thin one is effective in terms of thermal discoloration efficiency, cost, and simplicity. More practically, a thin-walled molded body made by injection molding processing of a thermoplastic resin such as polyvinyl chloride, polycarbonate, polyolefin, or polystyrene resin, or a vacuum heat molding processing by the film of the thermoplastic resin is used to obtain a target shape. Can be shaped. Note that the vehicle body 3 is not limited to a general-purpose vehicle body shape, but a body that can be divided, a personified person such as an animal, or a body modeled in other toy shapes is effective. The chassis 2 according to the invention of the present application is not limited to the chassis, but includes a part of the vehicle body components attached to the chassis or a molded body similar to the vehicle body.

When the vehicle body 3 is mounted on the chassis 2, the electric heating layer of the chassis 2
21 and the reversible thermochromic layer 31 of the vehicle body 3 are held in contact with or close to each other. Here, if the energizing heat generating layer 21 and the power supply battery are in an energizing state and the energizing heat generating layer 21 reaches a predetermined temperature range, the reversible thermochromic layer 31 immediately starts discoloring and changes its appearance.

In a system in which the energization of the energization heat generation layer 21 is controlled not only immediately after the vehicle body 3 is mounted but also in the running state, the system discolors during running to change colors, patterns and the like.

The reversible thermochromic layer 31 returns to the normal state in a state where the electricity to the electricity-generating layer 21 is cut off and the temperature of the layer is returned to room temperature or the vehicle body 3 is removed.

As described above, a single chassis 2 transforms into a running toy having different appearances, colors and patterns.

Embodiment 1 (see FIGS. 1 and 2) A driving element is mounted (not shown), and a bonnet, a window and a roof of a frame of a chassis which is configured to be self-propelled have a rectangular shape of about 2 cm × 3 cm. The chassis 2 is constructed by attaching a substrate having the planar heating layer 21.

The energization heating layer 21 is formed by printing with a copper-based energization heating paste, forms an electric circuit in series with a power source (1.5V AA type dry battery x 2), and generates heat at about 40 ° C.
The temperature is set to be controllable.

The body 3 is made of polyvinyl chloride resin (thickness of about 0.
3 mm), and this is molded by heating and vacuum molding into an arbitrary external shape having a contact surface with the electric heating layer 21.

An image of the driver is formed on the front window of the vehicle body 3 with the general printing ink, and the body excluding the remaining window portion is colored with the yellow general printing ink (non-color change layer 32).

Then, covering the non-color-change layer 32, having a color change point at 37 ℃,
The reversible thermochromic layer 31 is printed and formed by the reversible thermochromic ink that exhibits a red color below the temperature and is decolorized at 37 ° C. or higher.

When the vehicle body 3 was mounted on the chassis 2 and the energization heat generating layer 21 was energized, the body changed from a red body to a yellow body, and at the same time, an image 32 of the driver was revealed from the front window.

The color change and appearance change were reversibly reproduced by the temperature change, and the running toy 1 having various appearances could be obtained.

Example 2 A polyvinyl chloride resin was used in the same manner except that the reversible thermochromic layer 31 of Example 1 was replaced with a reversible thermochromic ink that was blue below 37 ° C. and decolorized above 37 ° C. The vehicle body 3 according to Example 1 is formed, and a spare vehicle body that can be mounted on the chassis 2 of the first embodiment is configured.

Example 3 (see FIGS. 3 and 4) Power source battery (1.5V AA type dry battery × 2) in a hollow frame.

Was configured.

The vehicle body 3 is molded into a crocodile appearance by heating and vacuum-molding a polyvinyl chloride resin film having a thickness of about 0.6 mm. The car body 3 has a discoloration point of 38 ° C. on the surface of the film before the molding and is less than the discoloration point. The reversible thermochromic layer 31 was formed by coloring the eye and body of the crocodile with a reversible thermochromic ink that turns brown at. Next, the body portion was printed with light brown of general printing ink, and scales and eyeballs were printed with brown. Then, the entire surface was printed with a white pigment ink.

When the vehicle body 3 configured as described above is mounted on the chassis 2 and the energization heat generating layer 21 is energized and heated, the body and eyes, which are normally colored brown, are visible. The brown colored layer is decolored to expose the brown eyeball and the non-discolored layer 32 in which brown scales are arranged on the light brown body.

Example 4 (not shown) According to Example 3, the appearance of a hippo was modeled with a polyvinyl chloride resin film, and the reversible thermochromic ink and non-color-changing ink were used to print the eye and the body. Then, the toy-shaped car body 3 was formed.

The vehicle body 3 is detachable from the chassis 2 of the second embodiment,
I was able to assemble and play the running toy 1 with various appearance shapes, colors, patterns, etc., on one chassis 2.
