【産業上の利用分野】[Industrial applications]

この考案は、トラクタ−のキャビンのドア構造に関する。 The present invention relates to a cabin structure for a tractor cabin.

【従来の技術及び考案が解決しようとする課題】[Problems to be solved by conventional techniques and devices]

キャビンに取り付けられるドアとしては、ドアの外周縁部を形成するドア枠に 透明ガラス板を取り付けたものが一般的であるが、このようなドア形態を採るも のは枠の材料が多くなることから生産コストが高くなったり、重量が重くなると いった不具合を有し、更に、枠付きであるから枠が占める部分だけ視界が悪くな るという欠点を有していた。 As a door to be attached to the cabin, a transparent glass plate is generally attached to the door frame forming the outer peripheral edge of the door. However, this type of door requires a lot of frame material. Therefore, the production cost is high and the weight is heavy. Further, since it has a frame, it has a drawback that the visibility is deteriorated only in the part occupied by the frame.

【0003】 特に、隣接耕耘作業を行なう場合には、キャビン室内から前輪の操舵角を確認 しながら同時にドアの窓越しに隣接境界部を注視する必要があるが、枠部分が大 きいと、耕起した部分と未耕地部分との境界が室内からはっきりと見えず、オペ レ−タは気疲れする欠点があった。 また、枠無のドアを示すものとしては、実開昭58−171715号公報が存 在するが、この公報に記載されたものは、ガラスで構成されたドアの内側に補強 フレ−ムを固着したものではなく、ガラスに直接にヒンジを設けて開閉自在とし たものであるから、ヒンジに強い衝撃が掛かるとその取付部に応力が集中してガ ラスが破損する恐れがあった。In particular, when performing adjacent tillage work, it is necessary to check the steering angle of the front wheels from the cabin interior while at the same time gazing at the adjacent boundary through the window of the door. The boundary between the raised area and the uncultivated area was not clearly visible from the room, and the operator had the drawback of being tired. In addition, as a frameless door, there is Japanese Utility Model Laid-Open No. 58-171715, but the one disclosed in this publication has a reinforcing frame fixed inside a door made of glass. However, since the hinge is directly attached to the glass and it can be opened and closed, if a strong impact is applied to the hinge, stress may concentrate on the attachment part and the glass may be damaged.

【課題を解決するための手段】[Means for Solving the Problems]

この考案は上記した欠点に鑑みて提案するものであって、視界性に優れ、且つ ドアの支持強度も充分確保できるキャビンドアを得ることを目的とし、次のよう な技術的手段を講じた。 即ち、後部支柱に開閉自在に枢着されたトラクタ−のキャビンドアであって、 該ドアは無枠で透明のガラスで構成されると共に、透明ガラスの内側に、上部フ レ−ムとその後部に連設された縦フレ−ムを有する補強フレ−ムを取り付けたこ とを特徴とするトラクタ−のキャビンドアの構成とする。 The present invention is proposed in view of the above-mentioned drawbacks, and the following technical means have been taken for the purpose of obtaining a cabin door having excellent visibility and sufficient support strength of the door. That is, it is a cabin door of a tractor pivotally attached to a rear pillar so that the door can be opened and closed. A cabin door of a tractor is characterized in that a reinforcing frame having a vertical frame continuously connected thereto is attached.

【実施例】【Example】

以下、図面に基づいてこの考案の実施例を説明する。 車体7の前後部に夫々前輪5、5と後輪6、6を軸架して設け、車体7の前部 には、原動機を内装したボンネット8を設け、車体7の後部には左右の後輪6、 6の上方及び内方を覆うフェンダ−9、9を設けている。左右のフェンダ−9、 9間の車体上には操縦席10を設け、操縦席10の下方から前記ボンネット8の 後端部に亘ってフロア11を設けている。 An embodiment of the present invention will be described below with reference to the drawings. Front and rear wheels 5, 5 and rear wheels 6, 6 are mounted on the front and rear portions of the vehicle body 7, respectively. A hood 8 having a prime mover is provided at the front portion of the vehicle body 7, and rear left and right rear portions are provided at the rear portion of the vehicle body 7. Fenders 9 and 9 are provided to cover the upper and inner sides of the wheels 6 and 6. A pilot seat 10 is provided on the vehicle body between the left and right fenders 9, and a floor 11 is provided from below the pilot seat 10 to the rear end of the hood 8.

【0006】 フロア11上の前側左右両側部には、前部支柱2a、2aを立設し、フロア1 1の後側左右両側部には、後部支柱2b、2bを立設し、これらの両支柱2a、 2bの上端部間には連結枠12、12を設け、これらの連結枠12、12の上に ル−フ13を載置して、ここにキャビン1を構成している。 3は透明ガラスで形成されたドアであり、このドア3の内側には、前後方向に 沿う上部フレ−ム15と、ドア3の中程にあって前後方向に沿う下部フレ−ム1 6と、これらの後部を相互に連結する上下方向の縦フレ−ム30とからなる側面 視コ字状の補強フレ−ム4が取り付けられている。補強フレ−ム4は、図1に示 すようにドア3の端縁から内側に向かって僅かに離れた部位に位置させて取り付 けられ、補強フレ−ム4の縦フレ−ム4の上下2ヵ所の隅部にヒンジ14、14 を介してドア3が後部支柱2b、2bに開閉自在に枢着されている。下部フレ− ム16の前部にはドアロック装置17が設けられ、ノブ32を回動操作すること によってドア3の開閉が行なえる。Front struts 2a, 2a are erected on both left and right front sides of the floor 11, and rear stanchions 2b, 2b are erected on both left and right rear sides of the floor 11. The connecting frames 12 and 12 are provided between the upper ends of the columns 2a and 2b, and the roof 13 is placed on these connecting frames 12 and 12 to form the cabin 1. Reference numeral 3 is a door made of transparent glass. Inside the door 3, there are an upper frame 15 extending in the front-rear direction and a lower frame 16 located in the middle of the door 3 extending in the front-rear direction. A reinforcing frame 4 having a U-shape in a side view, which is composed of a vertical frame 30 which vertically connects these rear parts to each other, is attached. As shown in FIG. 1, the reinforcing frame 4 is attached at a position slightly separated from the edge of the door 3 toward the inside, and the vertical frame 4 of the reinforcing frame 4 is attached. A door 3 is pivotally attached to the rear columns 2b and 2b so as to be openable and closable via hinges 14 and 14 at upper and lower corners. A door lock device 17 is provided at the front of the lower frame 16, and the door 3 can be opened and closed by rotating the knob 32.

【0007】 なお、この実施例では、ドアのガラスは前後2枚で構成され、後半分のガラス 18は上部側のヒンジ33により内外に開閉できる構成としている。 そして、これらのガラスの外周縁部にはシ−ル部材20が取り付けられ、ドア 3を閉鎖したときのキャビン1内の気密性が保たれるようにしている。 図3は補強フレ−ム4に対するドア3の取付構造を示すもので、ドア3に設け た取付孔21にリング状弾性部材22を嵌合し、この弾性部材22と補強フレ− ム4に設けた孔にはボルト23を挿通し、このボルト23に螺合したナット24 と補強フレ−ム4との間にはドア3を補強フレ−ム4の方向に押圧させるスプリ ング25を設けている。In this embodiment, the glass of the door is composed of two front and rear windows, and the glass 18 for the latter half can be opened and closed inside and outside by the hinge 33 on the upper side. A seal member 20 is attached to the outer peripheral edge of these glasses so that the airtightness inside the cabin 1 when the door 3 is closed is maintained. FIG. 3 shows a mounting structure of the door 3 to the reinforcing frame 4. A ring-shaped elastic member 22 is fitted in a mounting hole 21 provided in the door 3, and the elastic member 22 and the reinforcing frame 4 are provided. A bolt 23 is inserted into the hole and a spring 25 for pressing the door 3 in the direction of the reinforcing frame 4 is provided between a nut 24 screwed to the bolt 23 and the reinforcing frame 4. .

【0008】 上記の構成において、ドア3を開閉操作したときの軽い衝撃はドア3のシ−ル 部材20で吸収される。 一方、ドア3を強く閉めたときには、ガラス全体に強い衝撃が加わるようなこ とがあるが、そのような場合には、弾性部材22とスプリング25を撓ませなが らガラスが補強フレ−ム4から離れることになり、ガラスの一部、特にヒンジ1 4の取付部等に強い衝撃荷重が集中することがないからガラスが破損するような ことはない。In the above structure, a light shock when the door 3 is opened and closed is absorbed by the seal member 20 of the door 3. On the other hand, when the door 3 is strongly closed, a strong impact may be applied to the entire glass. In such a case, the glass is reinforced by the reinforcing frame 4 while the elastic member 22 and the spring 25 are not bent. Since the strong impact load is not concentrated on a part of the glass, especially the mounting portion of the hinge 14, etc., the glass is not broken.

【考案の作用効果】[Function and effect of the device]

この考案は前記の如く、後部支柱に開閉自在に枢着されたトラクタ−のキャ ビンドアであって、該ドアは無枠で透明のガラスで構成されると共に、透明ガラ スの内側に、上部フレ−ムとその後部に連設された縦フレ−ムを有する補強フレ −ムを取り付けたものであるから、ドアの重量は枠部材がない分だけ従来型に比 べて軽くなり、しかも、ドアの内側の前部支柱側には前方視界を妨げる補強フレ −ムがなく、前方視界が開けて隣接耕耘作業等もやり易くなると共に、ガラスド アを強固に支持することができて耐久性も向上する特徴を有する。 As described above, the present invention is a tractor cabin door pivotally attached to the rear pillar so that the door can be opened and closed. -Since a reinforcing frame having a vertical frame connected to the rear of the frame is attached, the weight of the door is lighter than the conventional type because there is no frame member, and the door is also There is no reinforcing frame on the inside of the front column that obstructs the front view, which allows the front view to be opened, making it easier to perform adjacent tillage work, etc. It has the characteristics that
