ある。In the figure, 1 is the driver's cab body, 2 is the upper window frame formed on the front of the driver's cab body 1, 3 is the lower window frame formed below the upper window frame 2, and 4 is the lower window frame 3. A crosspiece provided between the upper window frame 2, 5 is an upper window for opening and closing the upper window frame 2, and 6 is a lower window.
該下部窓6は周囲がシール材7を介して下部窓枠3に固
定されて、下部窓枠を塞いでいる。The periphery of the lower window 6 is fixed to the lower window frame 3 via a sealing material 7 to close the lower window frame.
前記上部窓5は、ガラス51の周囲にシール材52を介
してサツシュ53を取付け、該サツシュの両側の上部と
下部とにコロ54を回転自在に取付けている。The upper window 5 has a sash 53 attached around the glass 51 via a sealing material 52, and rollers 54 rotatably attached to the upper and lower parts of both sides of the sash.
一方、前記上部窓枠2の両側に上部窓のコロ54を案内
する為のレール8を取付け、該レールと連続するレール
9を運転室本体1の天井側に取付けている。On the other hand, rails 8 for guiding the rollers 54 of the upper window are attached to both sides of the upper window frame 2, and a rail 9 continuous with the rails is attached to the ceiling side of the cab body 1.
そして、前記コロ54をレール8に嵌め込み、第3図に

42を一体に形成している。The support 14 has an upper plate part 141 equipped with a shock absorber 15 made of an elastic material attached to the upper window frame 2, and is arranged at a lower part of the upper window frame perpendicularly to the upper plate part and from the upper plate part 141. A side plate portion 1 extending toward the rear of the driver's cab body 1
42 are integrally formed.
そして、第5図及び第6図に示すように、上部窓5が上
部窓枠2を塞いだ時、前記突起12が緩衝具15を介し
て支持具の上板部141に受けられることにより、支持
具14に上部窓5を支持できるようにしている。As shown in FIGS. 5 and 6, when the upper window 5 closes the upper window frame 2, the protrusion 12 is received by the upper plate part 141 of the supporter through the buffer 15. The upper window 5 can be supported by the support 14.
その際、下部窓6の上縁に前記パツキン13が接触する
ことにより、パツキン13が上部窓5の下縁と下部窓6
の上縁との間をシールできるようにしている。At that time, the gasket 13 contacts the upper edge of the lower window 6, so that the gasket 13 contacts the lower edge of the upper window 5 and the lower window 6.
This allows a seal to be formed between the upper edge of the
前記下部窓6は、その下端を中心として運転室本体1の
内方へ回動できるようになっている。The lower window 6 is rotatable inward of the driver's cab body 1 about its lower end.
すなわち、下部窓6の下端に軸受体18を装着し、該軸
受体の下部に形成した溝に前記下部窓枠3の下縁部に取
付けた軸17を嵌め込ませ、下部窓6を軸17を支点と
して回転自在に支持している。That is, a bearing body 18 is attached to the lower end of the lower window 6, and the shaft 17 attached to the lower edge of the lower window frame 3 is fitted into a groove formed in the lower part of the bearing body. It is rotatably supported as a fulcrum.
また下部窓6を上方に移動させれば、軸受体18の溝か
ら軸17が外れるように軸受体18を形成し、即ち、下
部窓6を下部窓枠3から取外し可能にしている。Further, when the lower window 6 is moved upward, the bearing body 18 is formed so that the shaft 17 is removed from the groove of the bearing body 18, that is, the lower window 6 can be removed from the lower window frame 3.
そして、軸受体18が軸17を中心として回転すること
により、下部窓6を運転室本体1の内方へ回動できるよ
うに支持している。The bearing body 18 rotates about the shaft 17, thereby supporting the lower window 6 so as to be rotatable inward of the driver's cab body 1.
なお、下部窓6はサツシュを備えていない。Note that the lower window 6 is not provided with a satush.
また、前記下部窓6には、内側の両側にロック機構を具
えた係合部材19を装着し、かつ該夫々の保合部材19
の間に取手20を取付けている。Further, the lower window 6 is equipped with engaging members 19 equipped with locking mechanisms on both sides of the inner side, and the respective retaining members 19 are attached to the lower window 6.
A handle 20 is attached between them.
一方、前記支持具14の側板部142に、前記係合部材
19と係合し得る閉止係合孔142aと、該閉止保合孔
より運転室本体1の内方へ位置する係合孔142bとを
穿設している。On the other hand, the side plate portion 142 of the support 14 has a closing engagement hole 142a that can be engaged with the engagement member 19, and an engagement hole 142b that is located inward of the driver's cab body 1 from the closing engagement hole. is installed.
そして、第5図に実線で示す如く、支持具の閉止係合孔
142aに下部窓の係合部材19を係合することにより
、下部窓4を下部窓枠3に対して閉じるようにする。Then, as shown by solid lines in FIG. 5, the lower window 4 is closed with respect to the lower window frame 3 by engaging the lower window engaging member 19 with the closing engagement hole 142a of the support.
また、第5図に破線で示す如く、保合部材19を前記保
合孔142bに係合することにより、下部窓4を開けた
よ・で個定しておくことができるようにする。Further, as shown by the broken line in FIG. 5, by engaging the retaining member 19 with the retaining hole 142b, the lower window 4 can be held individually in the open position.
なお、21は雨水の浸入を防止する為のシール材であっ
て、運転室本体1の前面に上部窓2および下部窓枠3を
取り囲むように配装されている。Note that 21 is a sealing material for preventing rainwater from entering, and is arranged on the front of the driver's cab body 1 so as to surround the upper window 2 and the lower window frame 3.
本考案は、上記の如く、上部窓枠2の支持具14によっ
て上部窓5の突起12を受けるようにしたので、支持具
14が上部窓5を確実に支持することができる。In the present invention, as described above, the protrusion 12 of the upper window 5 is received by the supporter 14 of the upper window frame 2, so that the supporter 14 can reliably support the upper window 5.
従って、第7図に示すように、上部窓5を運転室本体1
の天井側へ移動させた場合には、桟を設けた従来例と比
較すると、視界を阻害するものがなくなるので、それだ
け視界を拡くすることができる。Therefore, as shown in FIG.
When moved to the ceiling side, compared to the conventional example in which a crosspiece is provided, there is no obstruction to the view, so the field of view can be expanded accordingly.
また、上部窓5が支持具14に支持された際、パツキン
13によって上部窓5の下縁と下部窓6の上縁との間を
シールできるので、雨水が運転室本体1へ侵入するのを
防ぐことができる。Furthermore, when the upper window 5 is supported by the support 14, the gasket 13 can seal between the lower edge of the upper window 5 and the upper edge of the lower window 6, preventing rainwater from entering the cab body 1. It can be prevented.
以上の実施例により明らかなように、本考案によれば、
運転者の視界を拡大することができるので、それだけ視
