〔産業上の利用分野〕
本考案は、トラクタのキヤビン構造の改良に関
する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement in the cabin structure of a tractor.
従来、トラクタでは実開昭59−184269号公報に
示されるように、籠型の安全フレームを運転部に
取付けることにより、運転者を他物との接触や不
測の転倒等から保護するようにしていた。
Conventionally, as shown in Japanese Utility Model Application Publication No. 59-184269, a cage-shaped safety frame has been attached to the driving section of tractors to protect the driver from contact with other objects and accidental falls. Ta.
ところが、前記安全フレームでは雨や強い日差
しといつた厳しい自然環境からは運転者を保護し
得ないので、実開昭58−63170号公報に示された
もののように、運転部を覆うキヤビンを設け、こ
のキヤビンで運転者を自然環境や転倒等から保護
する構造のものが考えられた。
However, since the safety frame cannot protect the driver from harsh natural environments such as rain and strong sunlight, a cabin is provided to cover the driving part, as shown in Japanese Utility Model Application Publication No. 58-63170. This cabin was designed to protect the driver from the natural environment and falls.
しかしながら、上記の如くのキヤビンは、通
常、板材のプレス加工部品によつて構成されるも
のであるため、雨露等から運転者を保護する点は
満足できるものではあるが、転倒といつた強い衝
撃力が作用する場合の強度については芳しくない
ことが予測される。 However, since the above-mentioned cabin is usually constructed from pressed parts made of plate material, although it is satisfactory in terms of protecting the driver from rain and dew, It is predicted that the strength when force is applied is not good.
本考案の目的は、自然環境から運転者を守り易
いキヤビンを採用しながら、その強度を高めるこ
とにある。 The purpose of the present invention is to use a cabin that can easily protect the driver from the natural environment while increasing its strength.
上記目的のために本考案は、機体に対する止着
部を下部に有した左右一対の前支持部材と、左右
一対の後支持部材とで機体に支持されるキヤビン
の、後支持部材の前後幅を、前支持部材の前後幅
よりも広いものに設定するとともに、機体に取付
けられる前後方向視でアーチ型の安全フレーム
を、左右の後支持部材の内面に沿う状態に設け、
かつ、この安全フレームに後支持部材を支持させ
てあることによつてトラクタのキヤビンを構成す
るものである。
For the above purpose, the present invention has been developed to reduce the front and back width of the rear support members of the cabin, which is supported by the fuselage by a pair of left and right front support members each having a fixing portion for the fuselage at the bottom, and a pair of left and right rear support members. The safety frame is set to be wider than the longitudinal width of the front support member, and an arch-shaped safety frame attached to the fuselage is installed along the inner surface of the left and right rear support members,
Further, the rear support member is supported by this safety frame, thereby forming a cabin of the tractor.
一般に、運転部における運転席はキヤビン内部
の後端部近くに配置されるから、キヤビンの後支
持部材に沿わして取付けられたアーチ型の安全フ
レームが、搭乗運転者を他物との接触や不測の転
倒といつた強い外力から守る有効な保護作用を発
揮する。
Generally, the driver's seat in the operating section is located near the rear end of the cabin, so an arch-shaped safety frame installed along the rear support member of the cabin protects the driver from contact with other objects. It provides effective protection against unexpected falls and strong external forces.
そして、安全フレームは幅広な後支持部材の内
面に沿わしてあるから、キヤビン外部からはその
安全フレームは見えにくいものとなつて外観上好
ましいとともに、後支持部材は運転者に対して後
側に位置する都合上、前後幅広に構成してあつて
も作業走行上の視界の妨げになり難い点も好都合
である。 Since the safety frame is placed along the inner surface of the wide rear support member, the safety frame is difficult to see from outside the cabin, which is good for the appearance. Due to its location, it is also advantageous that even if it is configured to have a wide front and rear width, it will not easily obstruct the visibility during work travel.
また、前支持部材は後支持部材に比べて前後幅
が狭くしてあるので、良好な前方視界を得ること
ができ、作業走行において好ましいものとなる。 Further, since the front support member has a narrower longitudinal width than the rear support member, a good forward visibility can be obtained, which is preferable for traveling during work.
その結果、キヤビンと運転席との相対位置関係
に着目することにより、外力に対して有効な保護
作用を有する安全フレームを、運転者の視界の妨
げや外観の悪化を招くこと無くキヤビンに組み合
わせ配置でき、対自然環境だけでなく安全上でも
有効なキヤビン構造を合理的に構成して提供する
ことができた。
As a result, by focusing on the relative positional relationship between the cabin and the driver's seat, a safety frame that has an effective protective effect against external forces can be placed in combination with the cabin without obstructing the driver's view or deteriorating the appearance. We were able to provide a rationally configured cabin structure that is effective not only against the natural environment but also for safety.
