本発明はフォークリフトトラック等の産業車両における
フード開閉装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hood opening/closing device for an industrial vehicle such as a forklift truck.
従来この種の７−ドは上面に運転者用座席が設置され、

れ、開閉できるようになっている。Conventionally, this type of 7-door has a driver's seat installed on the top.
When running by side-opening internal combustion, the engine and motor should be covered, and when running, cover the batteries.The hood should be covered behind the hood so that it can be opened for engine inspection, maintenance, or battery replacement. The car body is 7 and I'm confused! It is supported on the fixed side of the vehicle body, such as weights, and can be opened and closed.
ところで、このフードの開閉操作にあｆＩＬ″Ｄ＃ｔａ

とつＫなっている。By the way, there is a problem with opening and closing the hood.
However, the operator must open and close the hood against the sum of the hood's own weight and the weight of the seat, and the total weight of the hood is extremely bulky, making opening and closing operations extremely difficult. This poor opening/closing operability results in neglect of initial inspections and periodic inspections, which is a major factor in shortening engine life and battery life.
を九、フードの全開状態においてはオーバヘッドガード
のりヤビツ−に７−ドを掛は止めするわけであるが、こ
の掛は止めを外すとフードが衝撃的に閉まる丸め、点検
中の作業員に不安感を与え、安全上も問題であった。9. When the hood is fully open, the overhead guard glue screw is hooked to prevent the hood from closing, but if this hook is removed, the hood closes abruptly, causing anxiety for the worker during inspection. This was a safety issue as well.
本発明はかかる従来の問題点に戚み、７−ドの開閉操作
性を向上し、点検整備の容易化を因襲、しかも安全上良
好なフード開閉装置を提供する４のである。The present invention addresses these conventional problems and provides a hood opening/closing device that improves the operability of opening and closing the 7-door, facilitates inspection and maintenance, and is also safe.

閉ｉシを防止してフードが緩慢な閉動を行うようにした
ものである。In order to achieve such an object, the present invention hinge-supports one end of the hood on a fixed side of the vehicle body, such as a vehicle frame or a counterweight, and a cylinder-type auxiliary spring mechanism is rotatably attached to one end of the hood that supports the hinge. The other part of this auxiliary spring mechanism is supported on the vehicle body fixed side corresponding to one end of the hood, which is the hinge support side, and the auxiliary spring mechanism is used to lift the worker's 7-door when the seat is opened. The opening operation force is significantly reduced by assisting the hood, and when the hood is closed, an impactful closing is prevented and the hood closes slowly.

配役されているものである。7- An operating grip S is provided protruding from the side of the seat 1 for opening and closing the door 2. A piston rod end 7 of a gas stop 17 as a cylinder-type auxiliary spring mechanism is attached to the inner surface 11 of the rear end of this 7-door 2 via a bracket 6.
a are rotatably connected. The cylinder end 7b of this gas stock door is rotatably supported by a cross plate 8 in the vehicle body frame via a bracket 9. As can be seen from FIG. 2, this cross plate 8 is placed at a position corresponding to the rear end of the 7-door when the 7-door is closed.

は緩慢に閉じられるようになっている。The moment HM due to the weight of the hood 2 and the moment GM of the gas strut are set to have a moment-opening characteristic as shown in FIG. 6. The difference between the moments HM and GM becomes the operating moment IM of the worker who opens and closes the hood 2. Looking at this operating moment IM and operating force, the worker can open the 7-door 2 by only using an operating force of 5 felijl in the initial stage of opening.
The operating force gradually becomes rare until it reaches about 112d+Dva degrees by opening the door 8, and with that Hsh- force, it is operated with a constant force until it exceeds -. You can open the 7th door with almost no operating force.The reverse is true when closing the hood.
is closing slowly.

For example, a striker is installed on the hood side, a locking mechanism is installed on the rear pillar 12 to engage the striker, and the grip 5 is held in place.
This structure is supported by four chains installed between the front door and the rear villa 12.

As shown in FIG. 4, a spring cylinder may be used in which a compression coil spring 70 is disposed inside the cylinder 7C to constantly press the piston 74 outward to apply thrust to the piston rod 7. Furthermore, 7 of the auxiliary spring mechanism 7
To support the cylinder end 7b, a recess 4 is provided in the counterweight 4 as shown in FIG.
+171 can also be fitted loosely.
以上本発明によれば、次に列挙する効果を奏する。As described above, according to the present invention, the following effects are achieved.
（１） 補助ばね機構によシアートの開操作力が軽減
されるためフードを開けての点検ψ整備作業が容易とな
り、エンジン寿命、ノくツテリ寿命を伸ばすことく寄与
する。(1) The auxiliary spring mechanism reduces the force required to open the seat, making inspection and maintenance work with the hood open easier, which contributes to extending the engine life and the exhaust life.
（２）フード全開時のフードの保持（倒れ防止）が容易
にまり、しかも作業員に不安感を与えることが少なくな
って安全上好ましい。(2) The hood can be easily held (prevented from falling) when the hood is fully opened, and the operator is less likely to feel uneasy, which is preferable from a safety standpoint.
（３）補助ばね機構がフードのヒンジ支持側端部に存在
している丸め、点検・整備作業を７−ドの横から身体を
のシ出して行なっても作業の邪魔にならず１点検り整備
性が向上する。(3) The auxiliary spring mechanism is located at the end of the hood on the hinge support side. Even if you do rolling, inspection, and maintenance work by extending your body out from the side of the 7-door, it will not interfere with the work and will allow you to perform one inspection. Improves maintainability.
（４） 補助ばね機構はｊｌＫフードと本体とを藺単
に連結するだけなので、オプシーンとして設定しやすく
、シかも−ｔ−Ｏ取付作業は補助ばね機構を伸長した状
態でしかもフードを圃けた伏線で清単に行うことがで龜
る。(4) The auxiliary spring mechanism simply connects the jlK hood and the main body, so it is easy to set up as an optional scene, and the auxiliary spring mechanism can be installed with the auxiliary spring mechanism extended and the hood opened. It is difficult to do it clearly.
（５）フード開閉操作力はガスストラットにあっては、
ガス封入圧力を加えるだけで、ばねシリンダにあっては
コイルばねのばね定数をかえるだけで藺拳ｌＩｃ１ｌｌ
１１１することができる。ｔたこの調整によ如フード全
開時のフード保持手段を廃止できる。(5) The operating force for opening and closing the hood is as follows for gas struts:
Simply apply the gas filling pressure, or in the case of spring cylinders, simply change the spring constant of the coil spring.
111. By adjusting the octopus, it is possible to eliminate the hood holding means when the hood is fully opened.
