Description

本発明は、運搬台車に関するものである。   The present invention relates to a transport cart.

荷物を載置して運搬する運搬台車として、下記特許文献に示すように荷物の載置板である長方形のベースの裏面にキャスターを取付けるとともに、ベースの端部に手押し棒を立設したものがあり、手押し棒を押すことで台車を移動し荷物を運搬する。
特開2006−51861号公報
As a transport cart for placing and transporting a load, as shown in the following patent document, a caster is attached to the back surface of a rectangular base that is a load placement plate, and a hand bar is erected at the end of the base. Yes, by pushing the hand bar, the carriage is moved to carry the luggage.
JP 2006-51861 A

この運搬台車の多くは、キャスターはベースの裏面の四隅に配設され、合計4個が取付けられている。   In many of these transport carts, casters are disposed at the four corners of the back surface of the base, and a total of four casters are attached.

そして、キャスターをベースの裏面に取付けるには、ベースに予め形成してあるボルト挿通孔に挿入するボルトなどで、キャスターに設けてある台座をベースに固定している。   And in order to attach a caster to the back surface of a base, the base provided in the caster is being fixed to the base with the volt | bolt etc. which are inserted in the bolt insertion hole previously formed in the base.

従来の運搬台車は、キャスターを台車本体に取付けるには、前記のように台車本体に予めボルト挿通孔を形成しておく必要があるため、必要以上のボルト挿通孔をベースに無駄に設けないようにするためにも、当然のことではあるがキャスターの配設位置にのみボルト挿通孔が形成される。   In order to attach the caster to the main body of the carriage, it is necessary to form the bolt insertion holes in the main body of the carriage in advance as described above, so that unnecessary bolt insertion holes should not be provided in the base. In order to achieve this, as a matter of course, the bolt insertion hole is formed only at the position where the caster is disposed.

そして、ボルト挿通孔が形成される部位は、例えば、ベースの4隅である4箇所であり、運搬台車は4輪構造となる。   And the site | part in which a bolt insertion hole is formed is four places which are the four corners of a base, for example, and a conveyance trolley becomes a four-wheel structure.

ところで、運搬台車で荷物を運搬する際、平坦な場所だけでなく、図6に示すように傾斜地、段差のある場所、窪地、溝などを乗越えなければならない場合もある。   By the way, when a load is transported by a transport cart, it may be necessary to get over not only a flat place but also an inclined place, a stepped place, a depression, a groove and the like as shown in FIG.

窪地・排水溝などの溝5を乗越える時、4輪構造の運搬台車の場合、前輪の2輪が溝5に嵌り込むと、この前輪の2輪を溝5から脱出させるためには、残りの後輪の2輪だけで荷物4の荷重を受けなければならず、台車本体が傾斜し不安定状態となるだけでなく、台車本体が動かなくなり運搬不能となることもある。   In the case of a four-wheel transport cart, when the front wheel is fitted into the groove 5, the two wheels of the front wheel are left in order to escape from the groove 5. The load of the load 4 must be received by only the two rear wheels, and not only the cart body tilts and becomes unstable, but the cart body does not move and may not be transported.

また、台車本体が傾くと、荷崩れを発生し、荷物が散在するだけでなく、運搬作業を行っている作業員が荷崩れをおこした荷物に押されて転倒したり、荷物の下敷になったり、荷物と壁などの間に挟まれるなどの人身事故の原因ともなるおそれがある。   In addition, if the cart body tilts, the cargo collapses and the luggage is scattered, and the worker who is carrying the product is pushed down by the cargo that caused the cargo collapse and falls down or becomes the underlay of the luggage. There is also a risk of personal injury such as being trapped between a baggage and a wall.

前記不都合は台車構造が4輪構造であることによるものであるが、ベースに対してキャスターの取付場所が予め四隅の4箇所に規制されているため、他の配列にキャスターが配設される運搬台車を得るには、別のタイプ(機種)の運搬台車を別途用意しなければならず、作業性のよくないものであった。   The inconvenience is due to the fact that the carriage structure is a four-wheel structure. However, since the mounting positions of the casters with respect to the base are regulated in advance at four locations at the four corners, the casters are arranged in other arrangements. In order to obtain a cart, another type (model) of transport cart must be prepared separately, which is not workable.

本発明の目的は前記従来例の不都合を解消するものとして、任意の箇所に自由に現場でもキャスターを取付けることが可能で、使用条件に合致する運搬台車を容易に確保でき、また、キャスター数を増すことで、窪地・排水溝などの溝も容易に乗り越えられ、使い勝手がよく作業性の向上を図れる運搬台車を提供するものである。   The purpose of the present invention is to eliminate the inconvenience of the conventional example, and it is possible to freely attach casters to any location at the site, easily secure a transport cart that meets the usage conditions, and reduce the number of casters. By increasing the number, it is possible to easily get over grooves such as depressions and drainage grooves, and provide a transport cart that is easy to use and can improve workability.

本発明は前記目的を達成するため、請求項1および請求項2に記載の本発明は、鉄製またはアルミニウム合金製の角パイプを縦横方向に付き合わせ溶接にて格子状に形成したフレームで構成される台車本体の下面で縦横のパイプにより区画が形成されるキャスターの取付けが予想される箇所の区画に、縦横のフレームの下面に当接させて、一部が区画の上下を連通させるように区画の開口を閉塞するキャスターの取付板をブラインドリベットにて取り付けたこと、および、キャスターの取付板は、対向する2箇所の角部の角度が90度の6角形状であることを要旨とするものである。 In order to achieve the above-mentioned object, the present invention is composed of a frame in which square pipes made of iron or aluminum alloy are formed in a lattice form by welding in vertical and horizontal directions. A section that is formed by vertical and horizontal pipes on the lower surface of the main body of the truck, and is in contact with the lower surface of the vertical and horizontal frame in a section where a caster is expected to be installed, and a section is partly connected to the upper and lower sides of the section The gist is that a caster mounting plate that closes the opening of the caster is attached with a blind rivet, and that the caster mounting plate has a hexagonal shape in which the angles of two opposing corners are 90 degrees. It is.

請求項1および請求項2記載の本発明によれば、台車本体を構成するフレームに対して、キャスターの取付けが予想される全ての箇所に取付板を予め取付けておいたから、使用条件に合致する箇所の取付板を選択して、これにキャスターの台座を取り付けるだけで、あるいは、使用しないキャスターを外すだけで、希望の態様の運搬台車を容易に確保できる。かかる作業は使用現場でも容易に行える。   According to the first and second aspects of the present invention, since the mounting plates are attached in advance to all the places where the casters are expected to be attached to the frame constituting the bogie body, the use conditions are met. By simply selecting the mounting plate at the location and attaching the pedestal of the caster to this, or by simply removing the unused caster, it is possible to easily secure the transport cart of the desired mode. Such work can be easily performed at the site of use.

請求項3記載の本発明は、フレーム上にベースを取付けた台車本体の裏面の周辺部の少なくとも四隅にキャスターを取付けた運搬台車において、前記少なくとも四隅に取付けたキャスターをつなぐ輪郭線の内側にキャスターを設けたことを要旨とするものである。   According to a third aspect of the present invention, there is provided a transport cart in which casters are attached to at least four corners on the periphery of the rear surface of a cart body having a base mounted on a frame. The gist of this is to provide.

請求項3記載の本発明によれば、台車本体の四隅に設けた合計4個のキャスターの他に、中央にキャスターが配設されるから、左右の前輪の2輪が溝に嵌っても、この状態でその後方の中央のキャスターと左右の後輪の2輪との、合計で台車本体を安定した状態に支持でき、台車本体が傾くことはない。   According to the third aspect of the present invention, in addition to a total of four casters provided at the four corners of the cart body, a caster is disposed in the center, so even if the two wheels on the left and right front wheels fit into the groove, In this state, the bogie body can be supported in a stable state in total, with the central caster at the rear and the left and right rear wheels, and the bogie body does not tilt.

同様にして、中央のキャスターが溝に嵌ったときは、前後左右の4輪で台車本体を支持できる。また、左右の後輪の2輪が溝に嵌っても、この状態でその前方の中央のキャスターと左右の前輪の2輪との、合計で台車本体を安定した状態に支持でき、台車本体が傾くことはなく、安全に順次溝を乗り越えていくことができる。   Similarly, when the central caster is fitted in the groove, the cart body can be supported by the front, rear, left and right wheels. In addition, even if the left and right rear wheels fit into the groove, the cart body in front of it and the two wheels of the left and right front wheels can be supported in a stable state in total. You can safely go over the groove sequentially without tilting.

以上述べたように本発明の運搬台車は、任意の箇所に自由に現場でもキャスターを取付けることが可能で、使用条件に合致する運搬台車を容易に確保でき、また、キャスター数を増すことで、窪地・排水溝などの溝も容易に乗り越えられ、使い勝手がよく作業性の向上を図れるものである。   As described above, the transport cart of the present invention can be freely installed on the site at any location, can easily secure a transport cart that matches the use conditions, and by increasing the number of casters, Grooves such as depressions and drainage grooves can be easily overcome, making it easy to use and improving workability.

FIG. 1 is a bottom view showing a first embodiment of a transport cart of the present invention, FIG. 2 is a bottom view showing a second embodiment, FIG. 3 is a plan view of the same, FIG. 4 is a side view of the same, and the cart body is made of iron or The frame 6 is composed of a square pipe made of aluminum alloy, and a base 7 that is a mounting plate made of iron or aluminum alloy joined to the upper portion of the frame 6.

前記フレーム6は角パイプを縦横方向に付き合わせ溶接にて格子状に形成したものであり、図示の例では縦方向の長尺な4本の角パイプに対して、横方向に短尺な複数の角パイプを接合し、縦横のパイプにより図示の例では縦約191mm、横約199mmの方形の15個の区画8が、縦列に3列、横列に5列形成される。   The frame 6 is formed by joining square pipes in the vertical and horizontal directions in a lattice shape, and in the illustrated example, a plurality of square pipes that are short in the horizontal direction are formed on the four long vertical pipes in the vertical direction. Square pipes are joined, and in the example shown in the figure, 15 rectangular sections 8 having a length of about 191 mm and a width of about 199 mm are formed into three rows in a vertical row and five rows in a horizontal row.

この格子状のフレーム6の下面で、キャスター2の取付けが予想される箇所の区画8に、キャスター2の取付板9をブラインドリベット10にて予め取り付けておく。図1の第1実施形態の例では取付板9の取付箇所は、台車本体の四隅の区画8の合計4箇所、中央の縦列で四隅の区画8の内側位置に合計2箇所、左右中央の区画8に合計2箇所であり、全部の合計が8箇所である。   On the lower surface of the lattice-like frame 6, a mounting plate 9 for the caster 2 is attached in advance with a blind rivet 10 to a section 8 where the caster 2 is expected to be attached. In the example of the first embodiment of FIG. 1, the mounting positions of the mounting plate 9 are four in total in the four corner sections 8 of the carriage body, two in total in the central position in the four corner sections 8 in the center column, and the left and right center sections. 8 is a total of 2 locations, and the total is 8 locations.

図2の第2実施形態の例では、取付板9の取付箇所は、前記第1実施形態から左右中央の区画8の合計2箇所を除いた全部の合計が6箇所である。   In the example of 2nd Embodiment of FIG. 2, the total of the attachment location of the attachment board 9 remove | excludes the total 2 places of the division 8 of the left-right center from the said 1st Embodiment, and is six places.

取付板9の形状は、対向する2箇所の角部の角度が90度の6角形状であり、90度の角部を縦横のフレーム6の下面に当接し、区画8の開口を閉塞するようにしてブラインドリベット10で固定する。   The shape of the mounting plate 9 is a hexagonal shape in which the angle of the two opposing corners is 90 degrees, and the 90-degree corners are in contact with the lower surfaces of the vertical and horizontal frames 6 so as to close the opening of the section 8. Then, fix with the blind rivet 10.

フレーム6の上面に配設されるベース7は、前記取付板9が配設されなかった区画8の部分にのみ取り付けられるものであり、図3に示すように取付板9のある区画8の箇所では、底部が取付板9で閉塞された、キャスター2の収納用の凹所に形成される。   The base 7 disposed on the upper surface of the frame 6 is attached only to the section 8 where the mounting plate 9 is not disposed, and as shown in FIG. Then, the bottom portion is formed in a recess for storing the caster 2, which is closed by the mounting plate 9.

以上のようにして使用条件に合致するように、取付板9の任意の箇所のものを選択して、取付板9にキャスター2を固定する。キャスター2は図1、図2、図4にも示すように、台座2bにキャスター本体2aを回転自在に取付けたものであり、台座2bをボルトとナット11で取付板9に固定する。   As described above, an arbitrary portion of the mounting plate 9 is selected so as to meet the use conditions, and the caster 2 is fixed to the mounting plate 9. As shown in FIGS. 1, 2, and 4, the caster 2 has a caster body 2 a rotatably attached to a pedestal 2 b, and the pedestal 2 b is fixed to a mounting plate 9 with bolts and nuts 11.

図示は省略したが、キャスター2の取付箇所は、台車本体の四隅の4箇所のみとすることもできるが、溝5を乗り越えられる構造とするには、図1、図2に示すように中央に縦列に2個以上のキャスター2を配置する。   Although illustration is omitted, the caster 2 can be attached to only four places at the four corners of the carriage body. However, in order to make the structure over the groove 5, as shown in FIGS. Two or more casters 2 are arranged in a column.

次に例えば図2に示す配置にキャスター2を取り付けて、溝5を乗り越える方法を図5について説明する。運搬台車を押して図5(b)のように溝5にキャスター2の左右の前輪が嵌っても、この状態でその後方の中央縦列の2輪のキャスター2と左右後の2輪のキャスター2との、合計4輪で台車本体を安定した状態に支持でき、台車本体が傾くことはない。   Next, for example, a method of attaching the casters 2 to the arrangement shown in FIG. Even if the left and right front wheels of the caster 2 are fitted into the groove 5 as shown in FIG. 5 (b) by pushing the transport carriage, in this state, the two rear casters 2 and the left and right rear two casters 2 Thus, the cart body can be stably supported by a total of four wheels, and the cart body does not tilt.

さらに前進して図5(c)の位置に達し、中央縦列の2輪のキャスター2のうちの前の1輪が溝5に嵌ったときは、前後左右の4輪のキャスター2と中央縦列の残りの後方の1輪のキャスター2の合計5輪で台車本体を安定状態に支持できる。   When the vehicle further moves forward to reach the position of FIG. 5 (c) and the front wheel of the two central casters 2 fits into the groove 5, the front / rear / right / left four casters 2 and the central vertical train The cart body can be supported in a stable state by a total of five wheels including the remaining one rear caster 2.

最後に、左右後輪の2輪のキャスター2が溝5に嵌っても、この状態でその前方の中央縦列の2輪のキャスター2と左右前輪の2輪のキャスター2との、合計4輪で台車本体を安定した状態に支持でき、いずれの場合も台車本体が傾くことはなく、安全に溝5を順次乗り越えていくことができる。   Finally, even if the two casters 2 of the left and right rear wheels are fitted in the groove 5, in this state, there are a total of four wheels, that is, the two casters 2 in the center vertical column and the two casters 2 in the left and right front wheels. The carriage main body can be supported in a stable state, and in any case, the carriage main body does not tilt, and the groove 5 can be safely and sequentially passed.

なお、溝5の幅は、前輪または後輪と、中央縦列の車輪との車輪ピッチを超えない範囲に限定されることはもちろんであり、図示の例では約214mmの幅の溝5であれば、乗り越えが可能である。   Of course, the width of the groove 5 is not limited to a range not exceeding the wheel pitch between the front wheel or the rear wheel and the wheel in the center column. In the illustrated example, the width of the groove 5 is about 214 mm. It is possible to get over.

そして、使用条件が変更になれば、ボルトとナット11を外して台座2bを取付板9から外しキャスター本体2aを除去したり、別の区画8に取り付けてある取付板9にキャスター2を付替えまたは新たにセットしたりして、新たな使用条件に合致する箇所にキャスター2を取り付ける。   If the usage conditions are changed, the bolts and nuts 11 are removed, the base 2b is removed from the mounting plate 9, the caster body 2a is removed, or the caster 2 is replaced with the mounting plate 9 attached to another section 8. Alternatively, the caster 2 is attached to a location that meets the new usage conditions by setting it anew.

台車本体を段積みした場合は、上段の台車のキャスター2が下段の台車の収納凹部内に入って取付板9で支承される。   When the cart bodies are stacked, the caster 2 of the upper cart enters the housing recess of the lower cart and is supported by the mounting plate 9.
