Description
本発明は、農用トラクタなどの作業車両に関する。 The present invention relates to work vehicles such as agricultural tractors.
ドアが完全に締まり切っていない状態、いわゆる半ドア状態を検出するとモータ駆動によりドアを完全にロックする車両用ドアクローザ装置が公知である（特許文献１）。 A vehicle door closer device is known that uses a motor to completely lock the door when it detects that the door is not completely closed, i.e., a so-called ajar state (Patent Document 1).
一般車両の場合はモータに電気を供給する配線をドア内部に配策することができるが、走行車体に作業機を装着して圃場内を作業するトラクタ等の作業車両においては、作業時に周辺の様子をよく確認できるようにドア全体が透明なガラスで構成されていることが多い。そのため、ドア内部に配線を通すと見栄えを悪くし、これを解消することが困難であった。 In the case of ordinary vehicles, the wiring that supplies electricity to the motor can be routed inside the door, but in work vehicles such as tractors that are fitted with implements and used in fields, the entire door is often made of transparent glass so that the driver can clearly see what is happening around them while working. Therefore, running wiring inside the door makes it look unsightly, and this has been difficult to resolve.
本発明は、ガラス張りのドアにドアクローザ装置を設けることが可能な作業車両を提供することを目的とする。 The present invention aims to provide a work vehicle that can be equipped with a door closer device on a glass door.

以下に、本発明に係る実施形態を図面に基づいて詳細に説明する。 Embodiments of the present invention are described in detail below with reference to the drawings.
図１は、トラクタを示すものであり、この走行車体１前部のボンネット２内部にディーゼルエンジンＥを搭載し、このエンジンＥの回転動力をミッションケース３内の変速装置に伝え、この変速装置で減速された回転動力を前輪４及び後輪５に伝えるようにしている。エンジンＥの後方に前輪４を操舵するステアリングハンドル６が装備され、更に、その後方には運転席７が設置されている。ミッションケース３の後上部には油圧シリンダケース８を備え、このシリンダケース８の左右両側には、油圧昇降機構の一部を構成するリフトアーム９が回動自在に取り付けられている。リフトアーム９は昇降用油圧シリンダ１０の伸縮作動により上下動する。車体後部には、トップリンク１１と左右のロアーリンク１２からなる３点リンク機構を設け、同リンク機構にロータリ作業機Ｒを装着し、リフトロッド１３を介してロアーリンク１２をリフトアーム９に連結することにより、作業機Ｒを昇降可能に構成している。 Figure 1 shows a tractor. A diesel engine E is mounted inside a hood 2 at the front of the vehicle body 1. The rotational power of this engine E is transmitted to a transmission in a transmission case 3, which then reduces the speed and transmits the rotational power to front wheels 4 and rear wheels 5. A steering wheel 6 for steering the front wheels 4 is mounted behind the engine E, and a driver's seat 7 is located behind it. A hydraulic cylinder case 8 is mounted at the upper rear of the transmission case 3, and lift arms 9, which form part of a hydraulic lifting mechanism, are rotatably attached to both the left and right sides of this cylinder case 8. The lift arms 9 move up and down by the extension and contraction of lifting hydraulic cylinders 10. A three-point link mechanism consisting of a top link 11 and left and right lower links 12 is mounted at the rear of the vehicle body. A rotary work implement R is attached to this link mechanism, and the lower links 12 are connected to the lift arms 9 via lift rods 13, allowing the work implement R to be raised and lowered.
前記ハンドル６や運転席７等は、キャビン１６によって覆われている。キャビン１６は、例えば防振ゴム等の弾性部材を介して車体に固定されてあり、車体の振動がキャビン１６に伝達されにくくしている。 The steering wheel 6, driver's seat 7, etc. are covered by a cabin 16. The cabin 16 is fixed to the vehicle body via an elastic member such as vibration-isolating rubber, which makes it difficult for vibrations from the vehicle body to be transmitted to the cabin 16.
尚キャビン１６は、フロア１７と、フロア１７左右前部に立設した前部支柱１８と、運転席７の後部左右に立設した後部支柱１９と、前後中間部に立設する中間支柱２０と、これら支柱上端同士を接続する上フレーム２１とによって一体化した枠組み構成とし、ルーフ２２で覆われている。そして、前記運転席７を支持するボックス状のシートフレーム２３、運転席７後面を囲う後部プレート２４、後輪５の上部を覆う左右フェンダ２５等を剛体化して強度を確保し、さらに、前後側面にはガラス窓部を構成し、左右開閉ドア２６部から昇降できる。 The cabin 16 is an integrated framework consisting of a floor 17, front pillars 18 erected at the left and right front of the floor 17, rear pillars 19 erected at the left and right rear of the driver's seat 7, intermediate pillars 20 erected in the middle between the front and rear, and an upper frame 21 connecting the upper ends of these pillars, and is covered by a roof 22. Strength is ensured by rigid components such as a box-shaped seat frame 23 supporting the driver's seat 7, a rear plate 24 surrounding the rear of the driver's seat 7, and left and right fenders 25 covering the tops of the rear wheels 5. Furthermore, glass windows are provided on the front and rear sides, and access can be provided through left and right opening doors 26.
開閉ドア２６は、ガラスドア形態で透過性を備え、上辺と下辺を有し前側は前部支柱１８に沿い後部下方はフェンダ２５に後部上方は中間支柱２０に沿う形状とした強化ガラス２６Ｇの周囲にシール材２６Ｓを嵌合構成してなる。開閉ドア２６の後部と前記中間支柱２０との間には、上下２か所にヒンジ２７を構成する。上下軸芯のヒンジ部２７ａとしたヒンジ２７は中間支柱２０及び開閉ドア２６各外側から固定しており、開閉ドア２６は外方に向けて回動でき、キャビン１６の左右を開放できる。 The opening and closing door 26 is a transparent glass door with upper and lower edges. Its front side fits along the front support pillar 18, its lower rear side fits along the fender 25, and its upper rear side fits along the intermediate support pillar 20. Two hinges 27, one above the other, are provided between the rear of the opening and closing door 26 and the intermediate support pillar 20. The hinges 27, with their upper and lower hinge portions 27a at their upper and lower axes, are fixed to the intermediate support pillar 20 and the outside of the opening and closing door 26, allowing the opening and closing door 26 to pivot outward, opening the left and right sides of the cabin 16.
開閉ドア２６の前部下方の外側には、アウタードアノブ２８を有する。また、対向する開閉ドア２６の内側にはインナードアノブ２９を設けている。そしてインナードアノブ２９を支持する開閉ドア２６の内側にロック機構３０を設けてなる。したがって、開閉ドア２６の外側からアウタードアノブ２８を引くとロック解除され、開閉ドア２６はヒンジ２７部中心に前方が開いてキャビン１６側方が開放できる。作業者は操縦席７に搭乗して開閉ドア２６を閉めてロック機構３０の係合作用で開閉ドア２６を閉鎖状態でロックする。なお、内側の作業者はインナードアノブ２９の操作でロック機構３０を解除して開閉ドア２６を開くことができる。 An outer door knob 28 is provided on the outside of the lower front portion of the door 26. An inner door knob 29 is provided on the inside of the opposing door 26. A locking mechanism 30 is provided on the inside of the door 26 that supports the inner door knob 29. Therefore, when the outer door knob 28 is pulled from the outside of the door 26, it is unlocked, and the door 26 opens forward around the hinge 27, allowing the side of the cabin 16 to be opened. An operator boards the cockpit 7, closes the door 26, and the locking mechanism 30 engages to lock the door 26 in a closed position. An operator on the inside can operate the inner door knob 29 to unlock the locking mechanism 30 and open the door 26.
開閉ドア２６のロック機構３０には、所謂半ドアの非完全ロック状態を検知して開閉ドア全閉の完全ロック状態に作動する電動ドアクローザ装置３１を備えている。このドアクローザ装置３１には非完全ロック状態を検知する検知手段（図示省略）や非完全ロック検知によってドアを完全ロック状態に作動する電動モータ（図示省略）を備えている。 The locking mechanism 30 of the door 26 is equipped with an electric door closer 31 that detects an incompletely locked state, i.e., the door is half-locked, and operates to fully lock the door. This door closer 31 is equipped with a detection means (not shown) that detects the incompletely locked state, and an electric motor (not shown) that operates to fully lock the door when an incompletely locked state is detected.
次に、ドアクローザ装置３１への電気用配線、すなわち電動モータ３１ｂへの電源供給用配線や検知手段３１ａの各種信号授受用配線、について説明する。なお、配線の種類としてはワイヤー、ケーブル、ハーネス等機器や用途によって区別して利用されるが、以下電線３３と総称する。前記ステアリングハンドル６を支持し上面には操作パネル（図示せず）を備えたダッシュボード３５の一側に沿って配策された電線３３は、フロア１７を経てフェンダ２５上面に沿わせている（図５）。フェンダ２５上面において、中間支柱２０の内面近傍を配策した後、開閉ドア２６の内側に設けるドアフレーム３６内を通過し、ドアクローザ装置３１へと配策する構成である。 Next, we will explain the electrical wiring to the door closer device 31, i.e., the wiring that supplies power to the electric motor 31b and the wiring that transmits and receives various signals from the detection means 31a. Note that while different types of wiring, such as wire, cable, and harness, are used depending on the device and purpose, they will hereinafter be collectively referred to as electrical wire 33. The electrical wire 33 is routed along one side of the dashboard 35, which supports the steering wheel 6 and has an operation panel (not shown) on its upper surface, and then passes through the floor 17 and along the top surface of the fender 25 (Figure 5). After being routed near the inner surface of the intermediate support pillar 20 on the top surface of the fender 25, it passes through the door frame 36 located on the inside of the opening and closing door 26 and is routed to the door closer device 31.
前記ドアフレーム３６は、開閉ドア１６の内側に前後に渡って固定保持されるもので、強化ガラス１６Ｇ内面とは適宜離れて設けられていてキャビン１６内の作業者が把持して開閉ドア２６の開閉動作を行うことができる。ドアフレーム３６の後端側は、前記ヒンジ２７のうち下方側のヒンジ２７に対応して共締めで固定するブラケット部材３６ａに適宜連結され、ドアフレーム３６の前端側は、強化ガラス１６Ｇに形成する取付穴３６ｂに適宜に固定される構成であるが、その位置は前記ロック機構３０及びドアクローザ装置３１を収容するケース部材３７の近傍としている。具体的には、ドアフレーム３６は、後半部は略水平姿勢を呈しその前後中間部から前方はケース部材３７方向に斜めに屈曲して接近し、さらに上方に屈曲してケース部材３７の上方に離れた取付穴３６ｂに至る形状としている（図２，図３）。 The door frame 36 is fixed to the inside of the retractable door 16 from front to back, positioned at an appropriate distance from the inner surface of the tempered glass 16G, so that an operator inside the cabin 16 can grasp it to open or close the retractable door 26. The rear end of the door frame 36 is appropriately connected to a bracket member 36a that corresponds to and fastens together with the lower one of the hinges 27, while the front end of the door frame 36 is appropriately fixed to a mounting hole 36b formed in the tempered glass 16G, located near the case member 37 that houses the lock mechanism 30 and door closer device 31. Specifically, the rear half of the door frame 36 is approximately horizontal, and the front half from the front-to-rear middle portion bends diagonally toward the case member 37, then bends upward to reach the mounting hole 36b located above the case member 37 (Figures 2 and 3).
前記ドアフレーム３６内に電線３３を通し、この電線３３はケース部材３７に最接近する箇所からドアフレーム３６外に出てケース部材３７内ドアクローザ装置３１の検知手段３１ａや電動モータ３１ｂに通じてことができる。 An electric wire 33 is passed through the door frame 36, and this electric wire 33 exits the door frame 36 from the point closest to the case member 37 and can be connected to the detection means 31a and electric motor 31b of the door closer device 31 inside the case member 37.
前記したように、ドアフレーム３６は操縦席７側方のフェンダ２５近傍からドアクローザ装置３１近傍に亘って設けられ、ドアフレーム３６にドアクローザ装置３１に電気を供給する電線３３を配策したから、略全面に透過性を有する開閉ドア２６に設けられたドアクローザ装置３１に電気を供給する電線３３を、外観を損なうことなく配策できる。 As described above, the door frame 36 is installed from near the fender 25 on the side of the driver's seat 7 to near the door closer device 31, and the electric wires 33 that supply electricity to the door closer device 31 are routed through the door frame 36. This allows the electric wires 33 that supply electricity to the door closer device 31 installed on the opening and closing door 26, which is almost entirely transparent, to be routed without damaging the appearance.
ここで、前記電線３３が、フェンダ２５からドアフレーム３６に至る構成について詳細に説明する。フェンダ２５（図例では左側）上面に形成したカップホルダ３８の外側面に余裕空間を形成し、この余裕空間に電線３３を適宜の弛みを持たせて配置する。開閉ドア２６の開閉に伴いドアフレーム３６の特に基端部が接近又は離反に対応するために、電線３３途中部に余裕を持たせるためである。そして、開閉ドア２６のヒンジ２７部に至る電線は、電線保護カバー３９に覆われてドアフレーム３６に入り込む構成である。なお、電線略カバー３９の固定は前記ブラケット部材３６ａ同様にヒンジ２７に対応して共締めされている（図６）。 Here, the structure of the electric wire 33 extending from the fender 25 to the door frame 36 will be described in detail. A slack space is provided on the outer surface of the cup holder 38 formed on the top surface of the fender 25 (left side in the illustration), and the electric wire 33 is placed in this slack space with an appropriate amount of slack. This allows for slack in the middle of the electric wire 33 to accommodate the approaching or separating movement of the door frame 36, particularly the base end, as the door 26 opens and closes. The electric wire leading to the hinge 27 of the door 26 is covered by an electric wire protection cover 39 before entering the door frame 36. The electric wire protection cover 39 is secured to the hinge 27 in the same manner as the bracket member 36a (Figure 6).
上記のように、フェンダ２５からドアフレーム３６まではヒンジ２７部を経由して電線が配策されるようになっているから、外観を損なうことなく電線３３を配策でき、開閉ドア２６の開閉による電線３３の影響を最小限にして配策できる。 As described above, the electrical wires 33 are routed from the fender 25 to the door frame 36 via the hinge 27, allowing the electrical wires 33 to be routed without compromising the appearance, and minimizing the effect of the opening and closing of the door 26 on the electrical wires 33.
前記のように、走行車体前部に設けた電源からキャビン１６内に配策された電線３３は、キャビン１６内においてフロア１７面を這わせて操縦席７側方のフェンダ２５に配策した構成であるから、走行車体前部に設けられた電源からドアクローザ装置３１に至るまで外観を損なうことなく電線を配策できる。 As described above, the electrical wires 33 routed from the power source located at the front of the vehicle body into the cabin 16 are routed along the surface of the floor 17 inside the cabin 16 and routed to the fender 25 on the side of the driver's seat 7. This allows the electrical wires to be routed from the power source located at the front of the vehicle body to the door closer device 31 without compromising the appearance.
次いで、図７、図８に基づきドアクローザ装置３１の改良構成について説明する。ドアクローザ装置３１の電動モータを作動する蓄電池４０を内装し、この蓄電池４０に充電する充電器４１をケース部材３７の近傍に配置するものである。そして、充電器用電線４２はキャビンルーフ２２から前部支柱１８に沿って配策する構成としている。なお、キャビンルーフ２２内には適宜電源からの電線を要するものとする。さらに、この充電器４１による電池４０充電のタイミングは、エンジンＥ駆動中でかつ開閉ドア２６は閉じのときとする。 Next, an improved configuration of the door closer device 31 will be explained with reference to Figures 7 and 8. The storage battery 40 that operates the electric motor of the door closer device 31 is installed inside, and a charger 41 that charges this storage battery 40 is located near the case member 37. The charger wire 42 is routed from the cabin roof 22 along the front support pillar 18. Note that an appropriate wire from a power source is required within the cabin roof 22. Furthermore, the timing for charging the battery 40 by this charger 41 is when the engine E is running and the opening/closing door 26 is closed.
このように、ドアクローザ装置３１内に蓄電器４０を設け、開閉ドア２６が閉まっているときに走行車体に設けられた電源から蓄電器４０に給電する構成としたから、略全面に透過性を有する開閉ドア２６に設けられたドアクローザ装置３１に電気を供給する電線４２について、外観を損なうことなく配策できる。開閉ドア２６が閉まっているときにドアクローザ装置３１の蓄電器４０に給電することにより、ドア閉時にドアクローザ装置３１に電線３３がつながっていなくても作動させることができる。 In this way, the capacitor 40 is provided within the door closer device 31, and power is supplied to the capacitor 40 from a power source provided in the vehicle body when the opening/closing door 26 is closed. This allows the electric wire 42 that supplies electricity to the door closer device 31 provided in the opening/closing door 26, which is almost entirely transparent, to be routed without damaging the appearance. By supplying power to the capacitor 40 of the door closer device 31 when the opening/closing door 26 is closed, the door closer device 31 can be operated even when the electric wire 33 is not connected to it when the door is closed.
また、キャビン１６に前部支柱１８を備え、開閉ドア２６が閉まっている状態におけるドアクローザ装置３１近傍まで前部支柱１８に沿って電線４２を配策するようにしたから、略全面に透過性を有する開閉ドア２６に設けられたドアクローザ装置３１に電気を供給する電線４２について、外観を損なうことなく配策できる。 In addition, the cabin 16 is equipped with a front support pillar 18, and the electrical wires 42 are routed along the front support pillar 18 up to the vicinity of the door closer device 31 when the opening/closing door 26 is closed. This allows the electrical wires 42, which supply electricity to the door closer device 31 installed on the opening/closing door 26, which is almost entirely transparent, to be routed without damaging the exterior appearance.
