上記特許文献１〜４は、いずれも空の台車を積み重ねた時、その高さを低くでき、収納空間を有効利用することにより、輸送コスト等を節減しようとする考案または発明を開示するものである。そしてその目的を達成するために、上記特許文献１は台板の上面に凹部を形成し上段の台車の車輪が該凹部に対応するようにしたものであり、特許文献２は台車を水平面内で９０度回転して十字状にクロス積みすることにより上段の台車の車輪が下段の台車の台板外に出るようにしたものであり、特許文献３は丸形容器用三角形台車であることから水平面内で６０度回転して積み重ねることにより上段の台車の車輪が下段の台車の台板外に出るようにしたものであり、特許文献４は台板に４つの車輪を非対称に設けることで上下段の台車の車輪の干渉が避けられるようにしたものである。
【０００４】
【発明が解決しようとする課題】
ところで、上記特許文献１に記載された台車では、台板の車輪取付位置に凹部を形成しなければならず強度が損なわれるおそれがあるので十分に高さを低くできない欠点がある。また、上記特許文献２に記載された台車は、車輪が下段の台車の台板外に出るようにするために、縦横比が概略３対２以上の長方形状の台車に限って実施できるものであり、正方形または正方形に近い形状の台車には実施できないものであるとともに、十字状であるので長手×長手の保管スペースを専有することとなり四隅はデッドスペースとなる欠点があった。また、特許文献３についても特殊な三角形台車であることから可能となるものであった。また、特許文献４に記載された台車は、車輪が非対称に設けられたものであることから通常の走行使用状態におけるバランスを悪くするという問題点があった。
本発明はこのような従来の台車の問題点を解消する積み重ね台車を提供しようとするものである。
【０００５】
【課題を解決するための手段】
そのために本発明の積み重ね台車は、略々正方形の台板を形成し、該台板の上面の四隅寄りに凹部を形成し、該台板の下面の四隅寄りの前記凹部に相当する部位に夫々車輪を設け、該台板の各辺の中間部分に切込を形成してなる台車であって、該台車を水平面内で略４５度回転しつつ多段に積み重ねることにより、上段の台車の車輪が下段の台車の前記切込中に垂下し、該車輪がさらに下段の台車の前記凹部に相対することで該台車と２段上に積み重ねられた台車の車輪との干渉が避けられるようにしたことを特徴とする。
このため、積み重ね時の高さが大幅に低くなるとともに、デッドスペースが生じることもなく保管効率が優れる。また、台板の四隅寄りに夫々車輪が設けられているので、搬送安定性を維持できる。
【０００８】
【発明の実施の形態】
次に図面に従い本発明の実施の形態を説明する。図１は本発明に係る積み重ね台車の平面図、図２はその斜視図、図３はこの台車の下面の斜視図である。この台車は、プラスチックにより一体に成形された略々正方形の台板１と、該台板の下面の四隅寄りに夫々設けられた車輪２とからなる。なお、該車輪２は、車輪支持部３を支持する垂直軸が取付板４に回転自在に支持され、該車輪２の転動方向が自在に変えられる所謂キャスターであり、該取付板４をボルト・ナット６を貫挿することによってこれを該台板の下面に取着している。
【０００９】
また、台板１は下面の中央部分７に斜格子状の補強リブ８を形成するとともに、該台板１の下面に該中央部分７を囲むように４つの桁体９を一体に形成している。また、該台板１の各辺の中間部分に半円状の切込１０を形成している。なお、切込１０は前記車輪２が遊嵌し得るような幅および奥行きに形成される。また、台板１の下面全体には格子状の補強リブ１１が形成される。
【００１０】
また、該台板１の上面には長方形状の浅窪からなる４つの係合部１２を前記桁体９とは水平面内で４５度回転した位置関係にて形成している。なお、１３は該係合部１２に形成された水抜孔である。
【００１１】
また、１４は台板１の上面の四隅寄りで前記車輪２の取付部上面に相当する部位に形成された円形の凹部、１５は該凹部に形成された水抜孔である。
【００１２】
このように構成した台車では、４つの車輪２により台板１が安定的に水平に支持される。そして、該台板の上面に荷物を積載することで種々の物品の運搬に使用される。そして、非使用時には図４〜図６に示したように、台車Ａの上に水平面内で略４５度回転して台車Ｂを積み重ねることによって、その上段の台車Ｂの車輪２が下段の台車Ａの切込１０中に垂下するので、車輪２と台板１との衝突が避けられ、積み重ね時の高さが大幅に低くなって収納に必要な空間を小さくすることができる。また、桁体９を一体に形成したことにより台板１が補強されるとともに、上段の台車Ｂの桁体９が下段の台車Ａの係合部１２に当接し該桁体９のズレ止めとなることから、積み重ね状態を安定させることができる。このため高く積み上げた際の倒壊、或いは、トラック輸送時の振動等による倒壊を防止できる。
また、桁体９を形成したことにより、上段の台車Ｂの車輪２が下段の台車Ａの台板１に接地しないようにできるので、車輪２が汚れていても台板１の積載面が汚れることなく衛生的である。
【００１３】
さらに、図６に示したように多段に積み重ねたとき、台車Ａの２段上に積み重ねられた台車Ｃの車輪２が該台車Ａの凹部１４に相対することから、台車Ａと２段上の台車Ｃの車輪２との干渉も避けることができる。このため、凹部１４を形成したことにより積み重ね時の高さを一層大幅に縮小することができる。
【００１４】
【発明の効果】
このように本発明に係る台車は、安定性を維持しつつ積み重ねることによって高さを大幅に低くでき、必要な収納空間を小さくできて優れた保管効率を有する。このため物流コストを軽減させるなど顕著な効果がある。

[Problems to be solved by the invention]
By the way, in the cart described in the above-mentioned Patent Document 1, there is a drawback that the height cannot be lowered sufficiently because a recess has to be formed at the wheel mounting position of the base plate and the strength may be impaired. Further, the cart described in Patent Document 2 can be implemented only in a rectangular cart having an aspect ratio of approximately 3 to 2 or more so that the wheels come out of the base plate of the lower cart. In addition, it cannot be applied to a cart having a square shape or a shape close to a square shape, and since it has a cross shape, it occupies a storage space of length × length and has a disadvantage that four corners become dead spaces. Patent Document 3 is also possible because it is a special triangular carriage. Moreover, the cart described in Patent Document 4 has a problem that the balance in a normal traveling use state is deteriorated because the wheels are provided asymmetrically.
The present invention seeks to provide a stacked cart that eliminates the problems of such conventional carts.
[0005]
[Means for Solving the Problems]
Therefore, the stacked carriage of the present invention forms a substantially square base plate , forms recesses near the four corners of the top surface of the base plate , and respectively corresponds to the recesses near the four corners of the bottom surface of the base plate. A wheel is provided, and a car is formed by forming a notch in an intermediate part of each side of the base plate, and the wheel of the upper base car is obtained by stacking the car in multiple stages while rotating approximately 45 degrees in a horizontal plane. It was suspended during the incision of the lower cart, and the wheel was further opposed to the recess of the lower cart so that interference between the cart and the cart wheels stacked on the second stage was avoided. It is characterized by.
For this reason, the height at the time of stacking is significantly reduced, and the storage efficiency is excellent without causing a dead space. Further, since the wheels are provided near the four corners of the base plate, the conveyance stability can be maintained.

DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a plan view of a stacked cart according to the present invention, FIG. 2 is a perspective view thereof, and FIG. 3 is a perspective view of the bottom surface of the cart. This carriage includes a substantially square base plate 1 integrally formed of plastic and wheels 2 provided near the four corners of the lower surface of the base plate. Incidentally, wheel 2, the vertical shaft supporting the wheel support 3 is rotatably supported on the mounting plate 4, the rolling direction of the wheel 2 is a so-called caster be changed freely, bolts mounting plate 4 -The nut 6 is inserted through the bottom surface of the base plate.
[0009]
In addition, the base plate 1 is formed with ribbed reinforcing ribs 8 in the central portion 7 on the lower surface, and four girders 9 are integrally formed on the lower surface of the base plate 1 so as to surround the central portion 7. Yes. Further, a semicircular cut 10 is formed in an intermediate portion of each side of the base plate 1. The notches 10 are formed in such a width and depth that the wheel 2 can be loosely fitted. A grid-like reinforcing rib 11 is formed on the entire lower surface of the base plate 1.
[0010]
Further, four engaging portions 12 made of rectangular shallow depressions are formed on the upper surface of the base plate 1 in a positional relationship rotated 45 degrees with respect to the beam body 9 in a horizontal plane. Reference numeral 13 denotes a drain hole formed in the engaging portion 12.
[0011]
Further, 14 is a circular recess formed in a portion corresponding to the upper surface of the mounting portion of the wheel 2 near the four corners of the upper surface of the base plate 1, and 15 is a drain hole formed in the recess.
[0012]
In the cart configured as above, the base plate 1 is stably supported horizontally by the four wheels 2. And it is used for conveyance of various articles | goods by loading a load on the upper surface of this base plate. When not in use, as shown in FIGS. 4 to 6, the wheel 2 of the upper carriage B is moved to the lower carriage A by rotating approximately 45 degrees on the carriage A in the horizontal plane and stacking the carriage B. Therefore, the collision between the wheel 2 and the base plate 1 can be avoided, and the height at the time of stacking can be greatly reduced, so that the space required for storage can be reduced. Further, the base plate 1 is reinforced by integrally forming the beam body 9, and the beam body 9 of the upper carriage B comes into contact with the engaging portion 12 of the lower carriage A to prevent the displacement of the beam body 9. Therefore, the stacked state can be stabilized. For this reason, it is possible to prevent collapse due to high stacking or collapse due to vibration during truck transportation.
Further, since the beam body 9 is formed, the wheel 2 of the upper carriage B can be prevented from coming into contact with the base plate 1 of the lower carriage A, so that the loading surface of the carriage 1 becomes dirty even if the wheels 2 are dirty. Hygienic without.
[0013]
Furthermore, since the wheels 2 of the carriage C stacked on the second stage of the carriage A are opposed to the recess 14 of the carriage A when stacked in multiple stages as shown in FIG. Interference with the wheel 2 of the carriage C can also be avoided. For this reason, the height at the time of stacking can be further greatly reduced by forming the recess 14.
[0014]
【The invention's effect】
As described above, the cart according to the present invention can be significantly reduced in height by being stacked while maintaining stability, and the required storage space can be reduced, thereby having excellent storage efficiency. For this reason, there are remarkable effects such as reducing logistics costs.
