Description

【考案の詳細な説明】（産業上の利用分野）この考案は車両のキヤブの改良に関し、詳しく
はキヤブ内の冷暖房性の改善（冷暖房の節約）技
術に関する。[Detailed Description of the Invention] (Field of Industrial Application) This invention relates to improving the cab of a vehicle, and specifically relates to a technology for improving the heating and cooling performance within the cab (saving heating and cooling costs).

イプ３を配設する。 In this case, a bedroom 9 is provided in the cab 4 behind the driver's seat 5, and an air supply pipe 3 is provided to guide air from the air conditioning unit 1 toward the bedroom 9.

但し、運転時はキヤブ４内全体の冷暖房のため、
冷暖房ユニツト１の出力を上げなければならな
い。 According to this, when a driver or the like takes a nap in the bedroom 9, the air from the air conditioning unit 1 is blown directly into the bedroom 9 via the air supply pipe 3, so that the effectiveness of the air conditioning in the bedroom 9 is improved. This has the advantage that the output of the air conditioning unit 1 can be reduced to save fuel.
However, since the entire cab 4 is heated and cooled during operation,
The output of the heating and cooling unit 1 must be increased.

（考案が解決しようとする問題点）ところで、キヤブ内には運転席とならんで助手
席などが配置されているが、例えば助手などのい
ないときにはキヤブ内全体を冷暖房する必要がな
く、換言すれば必要以上に広い居住空間を冷暖房
することになるという問題点があつた。(Problem that the invention aims to solve) By the way, in addition to the driver's seat, a passenger seat is arranged inside the cab, but when there is no passenger, for example, there is no need to cool or heat the entire inside of the cab. There was a problem in that a living space that was larger than necessary had to be heated and cooled.

（問題点を解決するための手段）この考案は、このような問題点を解決するた
め、車両のキヤブにおいて、ブロアからの空気に
より膨張する透明材質の袋を運転席以外の空間に
設ける。(Means for Solving the Problems) In order to solve these problems, this invention provides a bag made of a transparent material that is inflated by air from a blower in a space other than the driver's seat in the cab of a vehicle.

（作用）例えば、助手席が無人の場合は透明袋を膨張さ
せてキヤブ内の冷暖房空間を狭ると、運転席側の
冷暖房性は大幅に向上する。(Function) For example, when the passenger seat is unoccupied, the transparent bag is inflated to narrow the heating and cooling space in the cab, thereby greatly improving the heating and cooling performance on the driver's seat side.

（実施例）第１，２図において、キヤブ１０内には運転席
１１のほか、これと並んで助手席１２及び１３が

テンを示す。(Embodiment) In FIGS. 1 and 2, in addition to a driver's seat 11, passenger seats 12 and 13 are arranged in a cab 10. Further, a bed room 14 is provided behind these seats 11 to 13. Reference numeral 15 indicates a curtain that partitions the bedroom 14 from the seats 11 to 13 side.

そして、キヤブ１０内にはこの場合、ダクト１

換えると袋１８内の空気を排気口１９から排出す
るようになつている。２０は不使用時に袋１８を
折り畳んで格納する収納部を示す。 In this case, the duct 1 is inside the cab 10.
When a switching valve (not shown) installed in the bag 6 is switched to the supply side, a bag 18 made of a transparent material is expanded by a portion of the air from the blower 17 and occupies the space of the passenger seat 12. Note that when the air pressure inside the bag 18 reaches a predetermined value, the switching valve automatically shuts off and stops the supply of air, and when it is switched to the exhaust side, the air inside the bag 18 is exhausted from the exhaust port 19. It's becoming like that. Reference numeral 20 indicates a storage section in which the bag 18 is folded and stored when not in use.

このように構成したので、例えば助手のいない
運転時には袋１８を既述のように膨張させ、これ
により助手席１２の空間を占領すると、袋１８の
容積分だけキヤブ１０内の冷暖房空間が縮小する
ため、運転席１１側の冷暖房性は大幅に向上す
る。その結果、従来に比べて冷暖房ユニツト２１
の出力を落とすことにより、さらに燃費をかせぐ
ことが可能となる。 With this configuration, for example, when driving without an assistant, the bag 18 is inflated as described above, and when this occupies the space of the passenger seat 12, the air-conditioning space in the cab 10 is reduced by the volume of the bag 18. Therefore, the heating and cooling performance on the driver's seat 11 side is greatly improved. As a result, the heating and cooling unit is 21 times smaller than before.
By reducing the output of the engine, it is possible to further improve fuel efficiency.

この場合、袋１８は透明材質により作られてい
るため、運転席１１の視界を妨げることもない。
なお、助手席１３側にも、これを占領する袋（袋
１８と同一構成）を設けると、さらに運転席１１
側の冷暖房性の向上が図れる。 In this case, since the bag 18 is made of a transparent material, it does not obstruct the view of the driver's seat 11.
Furthermore, if a bag (same configuration as the bag 18) is provided to occupy this space on the passenger seat 13 side, the driver's seat 11
Improved side cooling and heating performance.

席側の冷暖房性の向上、ひいては燃費の改善が図
れるという効果が得られる。(Effects of the invention) In summary, according to this invention, when driving without an assistant, the transparent bag is inflated and the actual heating and cooling space inside the cab is reduced, improving the heating and cooling performance on the driver's seat side. This results in the effect of improving fuel efficiency.
