Description
【0001】
【発明の属する技術分野】
本発明は各種荷物の運搬用手持ち台車に関するものである。
【0002】
【従来の技術及び発明が解決しようとする課題】
従来から手持ち台車としては一輪のものや二輪のものなど様々なものが使用されている。しかし簡単な構造で一輪と二輪を兼用し、しかも使い勝手に優れた台車はあまり知られていない。また特に農作業用として収穫物を収納したコンテナを積載して農地等を移動し易い台車が望まれていた。
【0003】
【課題を解決するための手段】
本発明はこのような問題に対してなされたもので、一輪台車及び二輪台車の兼用として使用でき、且つ運搬し易い手持ち台車を提供するものである。
【0004】
即ち本発明は、荷台の手前側に手持ちハンドルを設け、該荷台の先端側に荷物の係止用ストッパーバーを設けた台車において、荷台の前後方向に架け渡した補強フレームに長孔を設けてタイヤを取付けたタイヤ支持部材をボルトナットを用いて該長孔に前後動可能に取付けたことを特徴とするものである。
そして固定された2本の補強フレームのそれぞれに前後動可能なタイヤ支持部材を取付け、これらタイヤ支持部材間にタイヤを固定することにより中央部に一輪を有する台車として使用でき、また固定された2本の補強フレームのそれぞれに前後動可能なタイヤ支持部材を取付け、各タイヤ支持部材にそれぞれタイヤを固定することにより二輪台車として使用できるものである。
【0005】
【実施例】
次に本発明を図面によりさらに説明する。
【0006】
(実施例1)
図1及び2に示すようにAl合金押出材からなる中空段付異形パイプの外側フレーム(1)の段部を内側且つ上向きに向けて矩形に組み付け、該段部にAl合金押出板からなる荷台板(2)を嵌合載置して前後方向が長尺の荷台(3)を形成した。そして該荷台(3)の下面側の長手方向にAl合金製押出材からなる溝形材を2本固定して補強フレーム(4)(4)とし、該補強フレーム(4)(4)の長手方向の先端部(荷台の先端側)に長手方向に沿って図4のように長孔(5)……を設けた。これら長孔(5)……には、図3に示すように角パイプをU字形に屈曲してその両側にボルト穴(7)を有する取付板(8)(8)をそれぞれ固定し、さらにU字形の下面中央にAl合金製鍔付丸パイプを片側に突出するように溶接固定してゴムタイヤ(9)を支持する車軸(10)を形成したタイヤ支持部材(6)(6)をボルトナット(12)で固定した。即ち図2に示すようにそれぞれのタイヤ支持部材(6)(6)はタイヤ(9)を取付けた側を外側に向けて固定したので二輪台車が得られる。
【0007】
さらに荷台(3)の手前側には、外周面に長手方向の溝を周方向に多数形成したAl合金製溝付パイプを屈曲させて左右それぞれのハンドル支脚一体部材(13)(13)を該荷台(3)に溶接固定し、これら一体部材(13)(13)間にAl合金製溝付パイプからなる補強及び荷物の滑落防止用の手前側ストッパーバー(14)を架け渡し溶接固定した。
また図5に示すように荷台(3)の先端部の両側の下面にはそれぞれAl合金パイプ(15)(15)を溶接固定し、該パイプ(15)(15)側面を貫通する蝶ネジ(16)を取付けて該パイプ(15)(15)内をスライドして任意の位置で固定できるAl合金製溝付パイプからなる先端側ストッパーバー(17)を取付けた。
【0008】
このような二輪台車は、左右のタイヤ(9)(9)がいずれも前後方向に移動できるので、荷台に載せる荷物の重心の位置によってタイヤ(9)(9)位置を前後にずらすことで荷物が運搬し易くなる。また荷台先端のストッパーバー(17)は前後方向に伸縮するので、荷物の大きさに合わせて位置決めすることで荷物を安定して荷台に載置できる。
【0009】
(実施例2)
図6及び図7に示すようにU字形の2本のタイヤ支持部材(6´)(6´)の下面中央にそれぞれAl合金製L形材(20)(20)を溶接固定し、タイヤ(9)の車軸として長ネジボルト(21)を貫通してその両端部を該L形材(20)(20)の車軸取付孔(22)に固定して一輪タイヤを構成した。このような一輪タイヤを2本のタイヤ支持部材(6´)(6´)のそれぞれの上端の取付板(8)を図4の台車の荷台下面の補強フレーム(4)(4)の長孔(5)にボルトナット止めすることで一輪台車が得られる。
【0010】
このような一輪台車は、二輪台車と同様タイヤ位置が前後に移動できるものであり、さらに一輪であるのでより狭い通路での運転が可能となる。
【0011】
なお一輪台車とする場合に実施例1の図3のようなタイヤ支持部材(6)にタイヤ(9)を取付けたものを1組だけ、図2とは反対側にタイヤを向けて補強フレーム(4)にボルトナット止めすることでも実現できるが、タイヤ取付部の強度の面などから図6のようなタイヤ支持部材による一輪の方が良好である。
またハンドル部の補強のために、手前側ストッパーバー(14)に代えて図8のような補強バー(23)をハンドル支脚一体部材(13)(13)に溶接固定してもよく、このような補強バー(23)はストッパーバー(14)の役目も果すものである。
さらに本実施例では荷台にはAl合金押出板(2)を固定してあるが、本発明では該押出板を外してフレームだけからなる荷台であっても、荷物が農業での収穫物を収納する大型のコンテナなどの場合は十分であり、しかも軽量である。
【0012】
【発明の効果】
このように本発明によれば使用する場所によって二輪と一輪を自由に選択でき、しかも荷物の大きさや載せる位置など重心の位置によってタイヤを前後に移動できるので運搬作業がし易いなどの効果を有する。特に農業収穫物を収納する矩形コンテナを前後方向に2〜4個程度載置して畑内の通路を移動するのに好適である。

TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE
[0002]
Problems to be solved by the prior art and the invention
Conventionally, various types of hand-held trolleys, such as one-wheeled and two-wheeled, have been used. However, there are not many known bogies that have a simple structure that can be used for one wheel and two wheels and that are easy to use. In particular, there has been a demand for a bogie which is easy to move on farmland by loading a container storing harvested products for agricultural work.
[0003]
[Means for Solving the Problems]
The present invention has been made to solve such a problem, and an object of the present invention is to provide a hand-held trolley that can be used as a one-wheeled trolley and a two-wheeled trolley and that is easy to carry.
[0004]
In other words, the present invention provides a hand-held handle on the front side of the loading platform, and in a truck provided with a stopper bar for locking the luggage on the tip side of the loading platform, providing a long hole in the reinforcing frame that is bridged in the front-rear direction of the loading platform. The tire support member to which the tire is attached is attached to the long hole so as to be able to move back and forth by using a bolt and a nut.
A tire support member capable of moving back and forth is attached to each of the two fixed reinforcing frames, and a tire is fixed between the tire support members so that the tire can be used as a truck having a single wheel at the center. A tire support member capable of moving back and forth is attached to each of the reinforcement frames, and a tire is fixed to each of the tire support members, so that the tire can be used as a two-wheeled vehicle.
[0005]
【Example】
Next, the present invention will be further described with reference to the drawings.
[0006]
(Example 1)
As shown in FIGS. 1 and 2, a step portion of an outer frame (1) of a hollow stepped pipe made of an extruded aluminum alloy is assembled in a rectangular shape with the stepped portion facing inward and upward, and a bed made of an extruded aluminum alloy plate is attached to the stepped portion. The plate (2) was fitted and mounted to form a carrier (3) having a long longitudinal direction. Then, two channel members made of an extruded material made of an Al alloy are fixed in the longitudinal direction on the lower surface side of the loading platform (3) to form reinforcing frames (4) and (4). A long hole (5)... As shown in FIG. As shown in FIG. 3, a rectangular pipe is bent into a U-shape, and mounting plates (8) and (8) having bolt holes (7) on both sides thereof are fixed to these long holes (5). A tire support member (6) (6) formed by welding and fixing an Al alloy flanged round pipe at the center of the lower surface of the U-shape so as to protrude to one side to form an axle (10) for supporting a rubber tire (9). It was fixed in (12). That is, as shown in FIG. 2, the tire supporting members (6) and (6) are fixed with the side on which the tire (9) is mounted facing outward, so that a motorcycle can be obtained.
[0007]
Further, on the front side of the loading platform (3), an Al alloy grooved pipe having a large number of longitudinal grooves formed on the outer peripheral surface in the circumferential direction is bent so that left and right handle support leg integrated members (13) and (13) are provided. It was welded and fixed to the loading platform (3), and a front side stopper bar (14) for reinforcing the aluminum alloy grooved pipe and preventing the load from slipping was fixed between the integrated members (13) and (13) by welding.
As shown in FIG. 5, Al alloy pipes (15) and (15) are welded and fixed to the lower surfaces on both sides of the tip end of the loading platform (3), respectively, and thumb screws (15) penetrating through the side surfaces of the pipes (15) and (15). 16) and a stopper bar (17) made of an Al alloy grooved pipe which can be slid in the pipes (15) and (15) and fixed at an arbitrary position.
[0008]
In such a two-wheeled vehicle, since the left and right tires (9) and (9) can move in the front-rear direction, the positions of the tires (9) and (9) are shifted back and forth depending on the position of the center of gravity of the load placed on the carrier. Is easy to carry. In addition, the stopper bar (17) at the tip of the carrier expands and contracts in the front-rear direction, so that the carrier can be stably placed on the carrier by positioning the stopper bar according to the size of the carrier.
[0009]
(Example 2)
As shown in FIGS. 6 and 7, L-shaped members (20) and (20) made of Al alloy are fixed by welding to the centers of the lower surfaces of two U-shaped tire support members (6 ′) and (6 ′), respectively. A single-wheel tire was constructed by passing a long screw bolt (21) as an axle and fixing both ends thereof to axle mounting holes (22) of the L-shaped members (20) and (20). The one-wheeled tire is attached to the mounting frame (8) at the upper end of each of the two tire support members (6 ') (6') by using the long holes of the reinforcing frames (4) and (4) on the lower surface of the carrier of FIG. The one wheel bogie can be obtained by fixing the bolts and nuts to (5).
[0010]
Such a one-wheeled vehicle can move the tire position back and forth similarly to the two-wheeled vehicle, and since it is a single wheel, it can be driven in a narrower passage.
[0011]
In the case of a single-wheeled vehicle, only one set of the tire supporting member (6) with the tire (9) attached thereto as shown in FIG. 3 of the first embodiment is directed to the reinforcing frame ( Although it can be realized by bolting nuts in 4), one wheel using a tire support member as shown in FIG. 6 is more preferable from the viewpoint of the strength of the tire mounting portion.
In order to reinforce the handle portion, a reinforcing bar (23) as shown in FIG. 8 may be welded and fixed to the handle support leg integrated members (13) (13) instead of the front side stopper bar (14). The reinforcing bar (23) also serves as a stopper bar (14).
Further, in this embodiment, the Al alloy extruded plate (2) is fixed to the carrier, but in the present invention, even if the extruded plate is removed and the carrier is composed of only a frame, the cargo can store harvested agricultural products. In the case of a large container or the like, the weight is sufficient and the weight is low.
[0012]
【The invention's effect】
As described above, according to the present invention, two wheels and one wheel can be freely selected depending on the place to be used, and the tires can be moved back and forth depending on the position of the center of gravity such as the size of the luggage and the position where the luggage is placed. . In particular, it is suitable for placing about 2 to 4 rectangular containers for storing agricultural crops in the front-rear direction and moving the passage in the field.
