〔産業上の利用分野〕
この発明は、体温により外観の一部分の形状が変化する
体温計に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] This invention relates to a thermometer whose external shape changes depending on body temperature.
一般に、体温計は単に体温を計るだけに使用されるもの
であるから、従来よりある水銀式の体温計にあっては、
１４ｈ比トの工夫は特になされてはいない。また、近年
急速に普及しつつあるデジタル式の体温計にあっては、
本体がプラスチックで形成されるため、従来のものに比
べて外観を形成する上での自由度は高いが、その自由度
はファツション性などの外観の向上に向けられている。Generally, thermometers are used only to measure body temperature, so conventional mercury-type thermometers
No particular improvements have been made to the 14h ratio. In addition, digital thermometers, which have become rapidly popular in recent years,
Since the main body is made of plastic, there is a greater degree of freedom in shaping the appearance compared to conventional products, but this degree of freedom is aimed at improving the appearance, such as fashionability.
ところで、これら体温計は幼児が使用することが多いが
、一般に幼児は検温をいやがり、従来あるいずれのタイ
プの体温計も幼児の興味を引（ようなものではないため
、なかなか体温を計らせないという問題点があった。By the way, these thermometers are often used by young children, but in general, young children are reluctant to have their temperature taken, and none of the conventional thermometers are interesting to young children, so it is difficult to have them take their temperature. There was a point.
そこで、この発明は上記従来技術の問題点に鑑み、幼児
が喜んで体温を計ら仕るように、外観に工夫を凝らした
体温計の提供をその目的とする。SUMMARY OF THE INVENTION In view of the above-mentioned problems of the prior art, it is an object of the present invention to provide a thermometer with an improved appearance so that infants will enjoy measuring their body temperature.
上記従来技術の問題点を解決するため、この発明によれ
ば、体温計本体の一部に、体温で温められると形状が変
化する形状変化部を備えてなる体温計を構成する。In order to solve the above-mentioned problems of the prior art, according to the present invention, a thermometer is constructed in which a part of the thermometer main body is provided with a shape-changing part that changes its shape when warmed by body temperature.
この構成において、形状変化部は、体温により所定形状
に変化するように記憶せしめた形状記憶合金で形成する
か、または体温により変形する形状記憶合金を介して変
化するような構造とすれば、構造が簡単であるから製造
面で都合がよい。In this configuration, the shape-changing portion is formed of a shape-memory alloy that is memorized so that it changes to a predetermined shape due to body temperature, or if the shape-changing portion is made of a shape-memory alloy that deforms due to body temperature. It is convenient in terms of manufacturing because it is simple.
この発明によれば、上記のごとく、体温計本体の一部に
、例えば体温で所定形状に変化するようにあらかじめ記
憶せしめた形状記憶合金からなる形状変化部あるいは形
状記憶合金を介して変化する形状変化部を設けてなるも
のであるから、形状変化部を例えば動物の顔に形成し、
体温により顔の表情が変化するようにすれば、幼児の関
心が高まり、すすんで体温を計らせるようになる。According to the present invention, as described above, a shape-changing portion made of a shape-memory alloy that is stored in advance so as to change into a predetermined shape due to body temperature, or a shape-changing portion that changes via the shape-memory alloy, is provided in a part of the thermometer body, for example. Since the shape-changing part is formed into the shape of an animal's face, for example,
By making facial expressions change depending on body temperature, infants will become more interested and will be more willing to have their temperature taken.

Note that in the figure, parts that are not directly involved in the movable mechanism, such as the body temperature display section, are omitted. A portion 8 corresponding to the eyes is opened in the face 4 of the head 3, and a display board 7 displaying the eyes 5 and eyelids 6 is provided inside the portion 8.
It is attached to one end of the crank 9 and is designed to move up and down. The other end of this crank 9 is connected to one end of the guide rod lO. The guide rod 10 has a flange portion 11 at the other end, and the flange portion 11 is housed in a large diameter portion 12 formed inside the thermometer body 2, and a bias spring is attached to the other end of the guide rod 10. 13 is inserted and presses the guide rod 10 downward. Further, the large diameter portion 1
2, a spring 14 made of a shape memory alloy is disposed on the opposite side of the flange portion 11 of the guide rod 10, and one end of the spring 14 extends to reach the vicinity of the temperature measuring section 15. Here, when the shape memory alloy spring 14 is not in use, it is compressed by being pressed by the bias spring 13, but when it reaches a predetermined temperature due to body temperature during use, the shape memory alloy spring 14 recovers its shape and stretches. Overcoming power, guide stick 1

されるようになっている。As described above, according to this embodiment, since the expression of the face 4 changes depending on the body temperature during use, this invention has the effect of attracting the infant's interest and causing the infant to willingly take the body temperature. 3(b), the illustrated thermometer 20 is provided with a bud 22 made of a shape memory alloy as a shape changing part on the upper part of the thermometer main body 21, and when in use, the thermometer 20 shown in FIG. As shown, the flower bud 22 is configured to recover its shape and open due to body temperature. In this case, unlike the embodiments described above, the shape changing section 22 utilizes the shape recovery action of the shape memory alloy itself, so that complex shape changes can be performed with an extremely simple structure compared to the embodiments described above. . Note that the shape changing section 22 is configured such that the heat of the temperature measuring section 23 is quickly transferred through a linear body having good thermal conductivity.
以上説明したように、この発明によれば、体温計本体の
一部に、例えば体温により動作する形状記憶合金を直接

で、幼児が検温をいやがることがなくなり、容易に体温
を計ることができるという効果がある。As explained above, according to the present invention, there is provided a thermometer in which a part of the thermometer body is provided with a shape-changing section that changes its shape by directly or indirectly using a shape memory alloy that operates based on body temperature, for example. Therefore, if the shape-changing part is made into something that attracts the infant's interest, such as the face of an animal, the facial expression will change depending on the body temperature when the temperature is taken, so the infant will not be reluctant to have the temperature taken. This has the effect of making it easy to measure body temperature.
なお、この発明は上記実施例に限定されるものではなく
