【産業上の利用分野】[Industrial applications]

本考案は、クローラ式運搬車に関するものである。 The present invention relates to a crawler type carrier.

【0002】[0002]

【従来の技術】[Prior art]

中央に走行輪、その前後に遊動輪と駆動輪とを配してこれらにクローラを巻き 掛けるとともに、車体を走行輪軸を支点にしてスイングできる構成にしたクロー ラ式運搬車が知られており、この構造の運搬車は荷物の積降しが省力的であると ともに、狭い路地への進入や階段登坂等もできることから、個別配達する重量物 の運搬等に用いられて重宝がられている。 A crawler-type transport vehicle is known in which a traveling wheel is arranged in the center, idler wheels and drive wheels are arranged in front of and behind it, and a crawler is wound around them, and the vehicle body can swing around the traveling wheel axle as a fulcrum. Cargo trucks with this structure are convenient for loading and unloading luggage, and because they can also enter narrow alleys and climb stairs, they are useful for transporting heavy items to be delivered individually.

【考案が解決しようとする課題】[Problems to be solved by the device]

このようなクローラ式運搬車は遊動輪が固定されているから、方向転換が思う にまかせない。このため、ハンドルを押し下げて遊動輪を浮かせ、走行輪の部分 だけで方向転換させていた。従って、速度が早いとき等にはこの操作が遅れてス ムーズな方向転換ができないということがあった。 本考案は、このような課題に対処するものであって、要するに、遊動輪を浮か せたときに接地するキャスターを取り付けたものである。 Since the idler wheels of such a crawler-type carrier are fixed, it is difficult to change direction. For this reason, the steering wheel was pushed down to float the idler wheel, and the direction was changed only at the running wheel. Therefore, when the speed is high, this operation may be delayed and a smooth direction change may not be possible. The present invention addresses such a problem and, in short, is equipped with a caster for grounding when the idler wheel is floated.

【0004】[0004]

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

以上の課題の下、本考案は、中央に走行輪、その前後に遊動輪と駆動輪とを配 してこれらにクローラを巻き掛け、遊動輪と走行輪間のクローラを接地させて走 行するとともに、車体を走行輪軸を支点にスイング可能に構成したクローラ式運 搬車において、走行輪軸から回動可能なアームを前延させ、このアームに遊動輪 を浮かせたときに接地、降ろしたときに軽く接地又は非接地となるキャスターを 取り付けたことを特徴とするクローラ式運搬車を提供したものである。 Under the above problems, according to the present invention, the traveling wheel is arranged in the center, the idler wheel and the drive wheel are arranged in front of and behind the wheel, and the crawlers are wound around them, and the crawler between the idler wheel and the traveling wheel is grounded to run. At the same time, in a crawler type transport vehicle in which the vehicle body can be swung around the traveling wheel shaft as a fulcrum, an arm that can rotate from the traveling wheel shaft is extended forward, and when the idle wheel is floated on this arm It provides a crawler-type carrier that is equipped with a lightly grounded or non-grounded caster.

【0005】[0005]

【作用】 以上の手段をとることにより、ハンドルを押し下げて遊動輪を浮かせると、キ ャスターと走行輪とが接地した状態になる。このとき、キャスターは水平面内で 自由に回動可能であるから、容易に方向転換等ができる。更に、この状態にする と走行抵抗が少なくなるから、平坦な道路等のときもスムーズに走行できる。With the above means, when the handle is pushed down to float the idler wheel, the caster and the running wheel are in contact with each other. At this time, since the casters can freely rotate in the horizontal plane, the direction can be easily changed. Further, in this state, running resistance is reduced, so that the vehicle can travel smoothly even on a flat road.

【実施例】【Example】

図1は本考案に係るクローラ式運搬車の側面図、図2は要部平面図であるが、 この運搬車は、エンジン10、ミッション12等を搭載する車体14の重心位置 やや後方に大径の走行輪16を、又、その前後に遊動輪18と駆動輪20とを配 し、これらにクローラ22を巻き掛けたものである。尚、駆動輪20は走行輪1 6よりも上方に設置し、クローラ22のうちの遊動輪18と走行輪16との間の 部分が接地面となるようにしてある。又、クローラ22の上辺は中央の走行輪1 6でも受けるようにしてある。 FIG. 1 is a side view of a crawler type carrier according to the present invention, and FIG. 2 is a plan view of an essential part. The carrier has a large center of gravity at a position of a center of gravity of a vehicle body 14 on which an engine 10, a mission 12, etc. are mounted. The running wheels 16 are also provided, and the idler wheels 18 and the drive wheels 20 are arranged in front of and behind them, and the crawlers 22 are wound around them. The drive wheel 20 is installed above the traveling wheel 16 so that a portion of the crawler 22 between the idle wheel 18 and the traveling wheel 16 serves as a ground contact surface. Further, the upper side of the crawler 22 is also received by the traveling wheel 16 at the center.

【0007】 この他、この運搬車には、車体14の前部に鉛直面内で回動する荷台フレーム 24が設けられており、この荷台フレーム24は車体14との間に介設される油 圧シリンダ26の伸縮によって起立姿勢と車台14上に前下り架設される傾斜フ レーム28の上に寝る傾斜姿勢とに亘って回動する。これにより、荷台フレーム 24を起立姿勢にして荷物30を積込み、安全な傾斜姿勢にして運搬する。In addition to this, this carrier is provided with a luggage carrier frame 24 that rotates in a vertical plane at the front portion of the vehicle body 14, and the luggage carrier frame 24 is provided between the vehicle body 14 and the oil carrier frame 24. By the expansion and contraction of the pressure cylinder 26, the pressure cylinder 26 is rotated between an upright posture and an inclined posture in which the pressure cylinder 26 lies on the inclined frame 28 which is installed on the chassis 14 in the forward and downward direction. As a result, the luggage frame 24 is placed in the upright posture and the luggage 30 is loaded and transported in the safe inclined posture.

【0008】 以上により、車体14は走行輪軸32を中心に前後にスイング可能な構成にな るから、傾斜フレーム28の後部に形成されたハンドル34を押し下げると、遊 動輪18は地上から浮き上がり、クローラ22の接地長は短くなる。ところで、 本考案は、走行輪軸32からこれを中心に回動可能なアーム36を前延させ、こ のアーム36にキャスター38を取り付けたのである。そして、このキャスター 38は、クローラ22が全長に亘って接地しているときには軽く接地しているか 又は非接地の状態であるが、ハンドル34を押し下げて遊動輪18を浮かしたと きには接地するのである。As described above, the vehicle body 14 is configured to be able to swing back and forth about the traveling wheel shaft 32. Therefore, when the handle 34 formed at the rear portion of the tilted frame 28 is pushed down, the idle wheel 18 is lifted from the ground and the crawler wheel is moved. The grounding length of 22 becomes short. By the way, according to the present invention, the arm 36 rotatable around the traveling wheel shaft 32 is extended forward, and the caster 38 is attached to the arm 36. The caster 38 is lightly grounded or ungrounded when the crawler 22 is grounded over the entire length, but is grounded when the handle 34 is pushed down to float the idler wheel 18. is there.

【0009】 図3はこの構成を示す要部断面図であるが、車体14を構成するフレーム40 にスプリング42でアーム36側に付勢されたピン44を設けるとともに、アー ム36にこのピン44が入り込む上下複数(本例では二つ)の孔46を形成した ものである。尚、ピン44の引っ込みは、操作ワイヤ48等によってハンドル3 4等に設けられたレバー(図示省略)の操作で行えるようにしてある。そして、 遊動輪18を下げてクローラ22全長を接地させるときにはピン44はアーム3 6の下側の孔46に入り込むように設定しておく。尚、この状態のとき、キャス ター38は軽く接地するか又は非接地の状態に設定しておく。FIG. 3 is a cross-sectional view of an essential part showing this configuration. A frame 44 constituting the vehicle body 14 is provided with a pin 44 biased toward the arm 36 by a spring 42, and the arm 36 is provided with this pin 44. A plurality of upper and lower holes (two in this example) through which the holes enter are formed. The pin 44 can be retracted by operating a lever (not shown) provided on the handle 34 or the like with an operation wire 48 or the like. Then, when the idler wheel 18 is lowered and the entire length of the crawler 22 is grounded, the pin 44 is set so as to be inserted into the lower hole 46 of the arm 36. Incidentally, in this state, the caster 38 is lightly grounded or set to a non-grounded state.

【0010】 次に、ピン44を孔46から抜いた後、ハンドル34を押し下げて遊動輪18 を浮かすと、キャスター38はその重量でその姿勢を維持しょうとするから、相 対的にフレーム40が上がって行き、ピン44は上側の孔46と合い、スプリン グ42の作用でこれに入り込んでロックされる。従って、図4の側面図に示すよ うにキャスター38と走行輪16とが接地する状態になる。尚、ピン44の孔4 6への入り込みを容易にするために、ピン44の先端を先細のテーパにすること 等が考えられる。この状態になれば、キャスター38は水平面内で自由に回動し て地上を転動するものであるから、方向転換も行い易いし、道路走行もスムーズ である。Next, after pulling out the pin 44 from the hole 46 and pushing down the handle 34 to float the idler wheel 18, the caster 38 tries to maintain its posture due to its weight, so that the frame 40 relative to each other. As it goes up, the pin 44 mates with the upper hole 46 and enters and is locked by the action of the spring 42. Therefore, as shown in the side view of FIG. 4, the casters 38 and the traveling wheels 16 come into contact with each other. In order to make it easier for the pin 44 to enter the hole 46, it is conceivable to taper the tip of the pin 44. In this state, the casters 38 freely rotate in the horizontal plane and roll on the ground, so that the direction can be easily changed and the road can be smoothly driven.

【発明の効果】【The invention's effect】

以上、本考案は、前記したものであるから、遊動輪を浮かせてキャスターと走 行輪とを接地させることで方向転換がし易くなる。又、この状態のときは走行抵 抗も小さいから、平地走行もスムーズである。一方、ハンドルを上げて遊動輪を 接地させると、クローラ全長が接地することになって階段登坂等も可能であるし 、このとき、キャスターは軽く接地又は非接地の状態であるから、走行抵抗とな ることもない。 As described above, according to the present invention, since the idler wheel is floated and the caster and the running wheel are grounded, it is easy to change the direction. Also, in this state, the running resistance is small, so that running on level ground is smooth. On the other hand, if the handle is raised to ground the idler wheel, the entire length of the crawler will be grounded, which allows climbing up stairs.At this time, the casters are lightly grounded or ungrounded, which may reduce running resistance. It won't happen.
