しかしながら、特許文献1に記載の搬送台車では、回動可能とされた第二連結部が当該搬送台車の側方に突出した形で設けられているため、第二連結部が設けられた部位に荷物の一部を載せることができなかった。また、第二連結部が上方に回動する構成とされているため、搬送台車に積まれた荷物の一部が第二連結部の上方にはみ出した状態では、第二連結部を回動させることができず、当該搬送台車と他の搬送台車との連結および連結解除を行うことができなかった。   However, in the transport cart described in Patent Document 1, the second connecting portion that is rotatable is provided in a shape protruding to the side of the transport cart. I couldn't load some of my luggage. In addition, since the second connecting portion is configured to rotate upward, the second connecting portion is rotated in a state in which a part of the luggage loaded on the transport carriage protrudes above the second connecting portion. It was not possible to connect and disconnect the transport cart and another transport cart.

本明細書で開示される技術は、連結部の上方に荷物の一部がはみ出した状態であっても連結および連結解除可能な台車を提供することを目的とする。   An object of the technology disclosed in the present specification is to provide a cart that can be connected and disconnected even when a part of the luggage protrudes above the connecting portion.

本明細書で開示される技術は、上面が荷台面とされた矩形状の荷台と、前記荷台の一端において前記荷台面の高さよりも上方に越えない高さに設けられた上側連結部と、前記荷台の前記一端とは反対側の他端において前記荷台面の高さよりも上方に越えない高さに設けられ、少なくとも一部が前記上側連結部の下側に重なり合うことで該上側連結部と連結される下側連結部と、前記上側連結部と前記下側連結部のいずれか一方に設けられ、前記荷台面に対して突出する突出部と、前記上側連結部と前記下側連結部のいずれか他方に設けられ、前記突出部と凹凸嵌合することで前記上側連結部と前記下側連結部とを連結する開口を有する開口形成部と、を備え、前記突出部と前記開口形成部の少なくとも一方に、前記突出部を前記開口へと案内する傾斜面が設けられ、前記下側連結部は、下方に押圧されることで前記荷台との境界部を支点として下方に回動する、台車に関する。   The technology disclosed in the present specification includes a rectangular cargo bed whose upper surface is a cargo bed surface, and an upper connecting portion provided at a height not exceeding the height of the cargo bed surface at one end of the cargo bed, The other end of the loading platform opposite to the one end is provided at a height not exceeding the height of the loading platform surface, and at least a part of the loading platform overlaps the lower side of the upper coupling portion. A lower connecting portion to be connected, a protruding portion that is provided on one of the upper connecting portion and the lower connecting portion and protrudes with respect to the cargo bed surface; and the upper connecting portion and the lower connecting portion. An opening forming portion provided on one of the other and having an opening for connecting the upper connecting portion and the lower connecting portion by engaging the protrusion with the projection, and the protruding portion and the opening forming portion. Guide the protrusion to the opening in at least one of the The inclined surface is provided that, the lower connecting portion is rotated downward as a fulcrum boundary between the loading platform by being pressed downward, to the bogie.

上記の台車では、突出部と開口形成部の少なくとも一方に突出部を開口へと案内する傾斜面が設けられているので、一方の台車と他方の台車とを連結させる際、他方の台車の上側連結部(下側連結部)を一方の台車の下側連結部(上側連結部)に近付けるだけで、突出部が傾斜面によって開口側へと滑らかに案内され、突出部と開口とが凹凸嵌合される。このとき、上側連結部と下側連結部とが接触することで下側連結部が下方へと押圧されて下側連結部が下方に回動する。このため、一方の台車または他方の台車を持ち上げることなく、上側連結部と下側連結部とを容易に連結させることができる。   In the above trolley, since at least one of the projecting portion and the opening forming portion is provided with an inclined surface for guiding the projecting portion to the opening, when one trolley is connected to the other trolley, the upper side of the other trolley Just by bringing the connecting part (lower connecting part) closer to the lower connecting part (upper connecting part) of one carriage, the projecting part is smoothly guided to the opening side by the inclined surface, and the projecting part and the opening are unevenly fitted. Combined. At this time, when the upper connecting portion and the lower connecting portion come into contact with each other, the lower connecting portion is pressed downward, and the lower connecting portion rotates downward. For this reason, an upper side connection part and a lower side connection part can be easily connected, without lifting one trolley | bogie or the other trolley | bogie.

また、下側連結部を下方に押圧するだけで、下側連結部が下方に回動して突出部が開口から外れるため、突出部または開口形成部に直接触れることなく、上側連結部と下側連結部との連結を解除することができる。さらに、上側連結部と下側連結部はいずれも荷台面の高さよりも上方に越えない高さに設けられているため、上側連結部および下側連結部の上方に荷物の一部がはみ出した状態で荷台面に荷物を載せることができる。この状態において、下側連結部を下方に回動することで、上側連結部と下側連結部の連結および連結解除を行うことができる。従って、連結部の上方に荷物の一部がはみ出した状態であっても連結および連結を解除することができる。   Also, simply pressing the lower connecting portion downward causes the lower connecting portion to rotate downward and the protruding portion to be removed from the opening, so that the upper connecting portion and the lower connecting portion are not directly touched with the protruding portion or the opening forming portion. The connection with the side connecting portion can be released. Furthermore, since both the upper connecting portion and the lower connecting portion are provided at a height that does not exceed the height of the loading platform surface, a part of the luggage protrudes above the upper connecting portion and the lower connecting portion. It is possible to place a load on the cargo bed surface. In this state, by rotating the lower connecting portion downward, the upper connecting portion and the lower connecting portion can be connected and disconnected. Accordingly, the connection and connection can be released even when a part of the luggage protrudes above the connection part.

前記突出部は、前記荷台面に対して前記荷台の内側から外側に向かって上方に傾斜する突出部側傾斜面を有し、前記開口形成部は、前記荷台面に対して前記荷台の内側から外側に向かって下方に傾斜する開口側傾斜面を有し、前記突出部と凹凸嵌合されるときに前記突出部側傾斜面と該開口側傾斜面とが接触するものとされ、前記突出部側傾斜面と前記開口側傾斜面の少なくとも一方が外側に膨らんだ曲面状とされていてもよい。   The protruding portion has a protruding portion-side inclined surface that is inclined upward from the inside of the loading platform to the outside with respect to the loading platform surface, and the opening forming portion is formed from the inside of the loading platform with respect to the loading platform surface. An opening-side inclined surface that is inclined downward toward the outside, and the protrusion-side inclined surface and the opening-side inclined surface are in contact with each other when the protrusion and the protrusion are fitted into the concave and convex portions; At least one of the side inclined surface and the opening-side inclined surface may be a curved surface bulging outward.

この構成によると、突出部を開口内へと案内させる際に、突出部側傾斜面と開口側傾斜面とによって突出部が開口側へと一層滑らかに案内されることとなるため、上側連結部と下側連結部とを一層連結させ易いものとすることができ、作業性を向上させることができる。   According to this configuration, when the protrusion is guided into the opening, the protrusion is guided more smoothly toward the opening by the protrusion-side inclined surface and the opening-side inclined surface. And the lower connecting portion can be more easily connected, and workability can be improved.

前記下側連結部は、該下側連結部の端部において前記荷台面の高さより下方に設けられた連結解除部を有してもよい。   The lower connection portion may include a connection release portion provided below the height of the cargo bed surface at an end portion of the lower connection portion.

荷台面に載置された荷物の一部が下側連結部の上方にはみ出ている場合、荷物が邪魔となって下側連結部を下方に押圧し難くなる虞がある。上記の構成によると、下側連結部が当該下側連結部の端部において荷台面の高さより下方に設けられた連結解除部を有しているため、荷台面に載置された荷物の一部が下側連結部の上方にはみ出ている場合であっても、連結解除部を下方に押圧することで、荷物が邪魔となることなく、下側連結部を下方に回動させることができ、作業性を向上させることができる。   When a part of the load placed on the loading platform surface protrudes above the lower connecting portion, it may be difficult to press the lower connecting portion downward due to the load. According to the above configuration, since the lower connecting portion has the connection releasing portion provided below the height of the loading platform surface at the end of the lower coupling portion, one of the loads placed on the loading platform surface is provided. Even when the part protrudes above the lower connection part, the lower connection part can be rotated downward by pressing the connection release part downward without causing the load to get in the way. Workability can be improved.

続いて、上側連結部30の構成について詳しく説明する。図4および図5に示すように、上側連結部30の板状部32は、その厚み(上下方向における寸法)が荷台20の厚みと比べて十分に小さいものとなっており、その上面32Aが荷台20の荷台面20Aと同一平面上となるように設けられている。   Then, the structure of the upper side connection part 30 is demonstrated in detail. As shown in FIGS. 4 and 5, the plate-like portion 32 of the upper connecting portion 30 has a thickness (dimension in the vertical direction) that is sufficiently smaller than the thickness of the loading platform 20, and its upper surface 32 </ b> A is It is provided so as to be on the same plane as the loading platform surface 20 </ b> A of the loading platform 20.

上側連結部30の突出部34は、図4および図5に示すように、その先端が荷台20の下面20Bよりも下方にはみ出ない寸法で下方に向かって突出している。突出部34の先端には、荷台20の内側から外側に向かって(後方から前方に向かって)上方に傾斜する傾斜面(以下、突出部側傾斜面と称する)34Aが設けられている。詳しくは、この突出部側傾斜面34Aは、当該突出部34の外側に向かってわずかに膨らんだ曲面状をなしている(図7参照)。   As shown in FIGS. 4 and 5, the protruding portion 34 of the upper connecting portion 30 protrudes downward with a dimension that does not protrude below the lower surface 20 </ b> B of the loading platform 20. An inclined surface (hereinafter referred to as a protruding portion-side inclined surface) 34 </ b> A that is inclined upward from the inner side to the outer side (from the rear to the front) of the loading platform 20 is provided at the tip of the protruding portion 34. Specifically, the protrusion-side inclined surface 34A has a curved surface that slightly swells toward the outside of the protrusion 34 (see FIG. 7).

続いて、下側連結部40の構成について詳しく説明する。下側連結部40は、その下面が、上述したように複数の取付バネ52によって荷台20に対して連結されることで、当該取付バネ52を介して、荷台20との境界部(荷台20の後端20C)を支点として、その全体が下方に回動できるようになっている。なお、図6は、下側連結部40が下方に回動した状態の台車10を表側から視た斜視図を示している。下側連結部40が下方に回動することで、載置部42の上面42Aが荷台20の荷台面20Aに対して傾斜した形となる(図6の一点鎖線参照)。   Then, the structure of the lower side connection part 40 is demonstrated in detail. The lower connecting portion 40 has a lower surface thereof connected to the loading platform 20 by the plurality of mounting springs 52 as described above, so that a boundary portion (the loading platform 20 of the loading platform 20 is connected to the loading platform 20 via the mounting spring 52). The entire rear end 20C) can be turned downward. FIG. 6 shows a perspective view of the cart 10 in a state where the lower connecting portion 40 is rotated downward from the front side. By rotating the lower connecting portion 40 downward, the upper surface 42A of the placing portion 42 is inclined with respect to the loading platform surface 20A of the loading platform 20 (see the dashed line in FIG. 6).

下側連結部40は、取付バネ52の自然状態においては、当該取付バネ52の弾性力によって、上述したように、載置部42の上面42Aが荷台20の荷台面20Aと同一平面上に位置した状態(第1姿勢の一例)とされる。この状態において、下側連結部40を上方から押圧することで、取付バネ52の弾性力に逆らって下側連結部40を下方に回動させることができる。そして、下側連結部40を下方に回動した状態(第2姿勢の一例)で、下側連結部40を下方に押圧していた力が無くなると、取付バネ52の弾性復帰力によって、下側連結部40は元の状態、即ち、載置部42の上面42Aが荷台20の荷台面20Aと同一平面上に位置した状態に復帰する。なお、取付バネ52の弾性力は、下側連結部40を小さな力で押圧することで回動できるように調整されている。   In the natural state of the mounting spring 52, the lower connecting portion 40 is positioned on the same plane as the loading surface 20 </ b> A of the loading platform 20 as described above by the elastic force of the mounting spring 52. It is set as the state (an example of a 1st attitude | position). In this state, by pressing the lower connecting portion 40 from above, the lower connecting portion 40 can be rotated downward against the elastic force of the mounting spring 52. When the force that is pressing the lower connecting portion 40 downward is lost in the state where the lower connecting portion 40 is rotated downward (an example of the second posture), the elastic return force of the mounting spring 52 causes the lower connecting portion 40 to move downward. The side connecting portion 40 returns to the original state, that is, the state where the upper surface 42A of the mounting portion 42 is located on the same plane as the loading surface 20A of the loading platform 20. The elastic force of the mounting spring 52 is adjusted so that it can be rotated by pressing the lower connecting portion 40 with a small force.

開口形成部44に形成された開口44Aは、図2に示すように、平面視において前後方向を長軸方向とする楕円状となるように開口している。この開口44Aは、その内部に突出部34を挿入させることが可能な大きさとされている。上側連結部30と下側連結部40とを連結させる際には、下側連結部40の開口形成部44に形成された開口44A内に、上側連結部30の突出部34が挿入されることで、当該開口44Aと当該突出部34とが凹凸嵌合され、これにより、上側連結部30と下側連結部40とが連結されるようになっている。   As shown in FIG. 2, the opening 44 </ b> A formed in the opening forming portion 44 is open so as to have an elliptical shape with the front-rear direction being the major axis direction in plan view. The opening 44A has a size that allows the protrusion 34 to be inserted therein. When the upper connecting portion 30 and the lower connecting portion 40 are connected, the protruding portion 34 of the upper connecting portion 30 is inserted into the opening 44A formed in the opening forming portion 44 of the lower connecting portion 40. Thus, the opening 44 </ b> A and the protrusion 34 are concavo-convexly fitted, so that the upper connecting part 30 and the lower connecting part 40 are connected.

なお、上述したように、開口形成部44は、平面視において上側連結部30の板状部32と略同形状とされ、かつ、板状部32よりも一回り大きい大きさとされているので、上側連結部30と下側連結部40とが連結される際には、当該開口形成部44内に板状部32が入り込むことで、突出部34が開口44A内に挿入される。   As described above, the opening forming portion 44 has substantially the same shape as the plate-like portion 32 of the upper connecting portion 30 in a plan view, and has a size that is slightly larger than the plate-like portion 32. When the upper connecting portion 30 and the lower connecting portion 40 are connected, the protruding portion 34 is inserted into the opening 44 </ b> A by the plate-like portion 32 entering the opening forming portion 44.

ここで、下側連結部40の開口形成部44は、その上面が上側連結部30における板状部32の下面32Bよりもわずかに下方に位置するように設けられている。従って、上側連結部30と下側連結部40とが連結された状態では、上側連結部30における板状部32の下面32Bと下側連結部40における開口形成部44の上面44Cはわずかに離間した状態となる。このため、上側連結部30と下側連結部40とが連結された状態において、当該上側連結部30と当該下側連結部40とが上下方向において互いに干渉し合うことがなく、前後方向に連結されたいずれかの台車の自在車輪が接地面から離れることがないものとなっている。   Here, the opening forming portion 44 of the lower connecting portion 40 is provided such that the upper surface thereof is positioned slightly below the lower surface 32 </ b> B of the plate-like portion 32 in the upper connecting portion 30. Therefore, in a state where the upper connecting portion 30 and the lower connecting portion 40 are connected, the lower surface 32B of the plate-like portion 32 in the upper connecting portion 30 and the upper surface 44C of the opening forming portion 44 in the lower connecting portion 40 are slightly separated. It will be in the state. For this reason, in a state where the upper connecting portion 30 and the lower connecting portion 40 are connected, the upper connecting portion 30 and the lower connecting portion 40 do not interfere with each other in the vertical direction, and are connected in the front-rear direction. The free wheel of any one of the carts does not leave the ground plane.

開口形成部44における開口44Aの後側には、図5に示すように、荷台20の内側から外側に向かって(後方から前方に向かって)下方に傾斜する傾斜面(以下、開口側傾斜面と称する)44Bが設けられている。詳しくは、開口側傾斜面44Bは、上側連結部30の突出部34における突出部側傾斜面34Aと同様に、当該突出部34の外側に向かってわずかに膨らんだ曲面状をなしている(図7参照)。なお、この開口側傾斜面44Bは、突出部側傾斜面34Aとほぼ同じ高さに設けられている。   As shown in FIG. 5, on the rear side of the opening 44 </ b> A in the opening forming portion 44, an inclined surface (hereinafter referred to as an opening-side inclined surface) that is inclined downward from the inside to the outside of the loading platform 20 (from the rear to the front). 44B) is provided. Specifically, the opening-side inclined surface 44B has a curved surface that slightly bulges toward the outside of the protruding portion 34, like the protruding portion-side inclined surface 34A of the protruding portion 34 of the upper connecting portion 30 (see FIG. 7). The opening side inclined surface 44B is provided at substantially the same height as the protruding portion side inclined surface 34A.

また、下側連結部40の後側における左右方向の両端にそれぞれ設けられた連結解除部46は、載置部42の上面42Aに対して下方に段差をなして設けられることで、足のつま先等で下方に押圧し易いものとなっている。従って、下側連結部40を下方に回動させる際には、連結解除部46を足のつま先等で下方に押圧することで、下側連結部40を容易に下方に回動させることができる。   In addition, the connection release portions 46 provided at both ends in the left-right direction on the rear side of the lower connection portion 40 are provided with a step difference downward with respect to the upper surface 42A of the placement portion 42, so that the toes of the foot Etc. so that it can be easily pressed downward. Accordingly, when the lower connecting portion 40 is rotated downward, the lower connecting portion 40 can be easily rotated downward by pressing the connection release portion 46 downward with a toe of a foot or the like. .

上側連結部30と下側連結部40とが連結されている状態において、連結解除部46または下側連結部40のいずれかの部位が下方に押圧されて下側連結部40が下方に回動することで、上側連結部30に設けられた突出部34が下側連結部40に設けられた開口44Aから抜け、これにより、連結が解除される構成となっている。   In a state where the upper connecting portion 30 and the lower connecting portion 40 are connected, either the connection releasing portion 46 or the lower connecting portion 40 is pressed downward, and the lower connecting portion 40 rotates downward. By doing so, the projecting portion 34 provided in the upper connecting portion 30 comes out of the opening 44A provided in the lower connecting portion 40, and thereby the connection is released.

なお、荷台20の前端20Bと上側連結部30の突出部34との間の間隔は、下側連結部40の後端と下側連結部40の開口44Aとの間の間隔よりもわずかに大きいものとされている。このため、一方の台車10の突出部34が他方の台車の開口内に挿入される際に、他方の台車の荷台の前端が一方の台車10の下側連結部40に干渉しないようになっている。   In addition, the space | interval between the front end 20B of the loading platform 20 and the protrusion part 34 of the upper side connection part 30 is slightly larger than the space | interval between the rear end of the lower side connection part 40, and the opening 44A of the lower side connection part 40. It is supposed to be. For this reason, when the protrusion 34 of one cart 10 is inserted into the opening of the other cart, the front end of the loading platform of the other cart does not interfere with the lower connection portion 40 of the one cart 10. Yes.

以上が本実施形態に係る台車10の構成であり、続いて、当該台車10と他の台車110とを連結させる方法および連結を解除する方法について図7および図8を参照して説明する。なお、図7および図8では、後方の台車110の各部位については、前方の台車10の各部に付した参照符号に数字100を加えたものを示すものとする。後方の台車110の各部位における構造、作用、及び効果については、上述した台車10と同一である。   The above is the configuration of the carriage 10 according to the present embodiment. Next, a method for connecting the carriage 10 and another carriage 110 and a method for releasing the connection will be described with reference to FIGS. 7 and 8. 7 and 8, each part of the rear carriage 110 is represented by adding reference numeral 100 to the reference numerals attached to the respective parts of the front carriage 10. The structure, operation, and effect of each part of the rear carriage 110 are the same as those of the above-described carriage 10.

まず、本実施形態の台車10を他の台車110と連結させる方法について説明する。台車10に対して他の台車110とを前後方向に連結させる際には、図7の上段に示すように、後方の台車110の前端部に設けられた上側連結部130を、前方の台車10の後端部40に設けられた下側連結部40に近付ける。このとき、上述したように、後方の台車110の上側連結部130における板状部132の上面132Aと、前方の台車10の下側連結部40における載置部42の上面42Aとは、高さがほぼ一致するものとされる。また、後方の台車110の上側連結部130における突出部134の突出部側傾斜面134Aと、前方の台車10の下側連結部40における開口形成部44の開口側傾斜面44Bとは、高さがほぼ一致するものとされる。   First, a method for connecting the cart 10 of this embodiment to another cart 110 will be described. When the other carriage 110 is connected to the carriage 10 in the front-rear direction, the upper connecting portion 130 provided at the front end of the rear carriage 110 is connected to the front carriage 10 as shown in the upper part of FIG. It approaches the lower connection part 40 provided in the rear end part 40. At this time, as described above, the upper surface 132A of the plate-like portion 132 in the upper coupling portion 130 of the rear carriage 110 and the upper surface 42A of the mounting portion 42 in the lower coupling portion 40 of the front carriage 10 are as high as possible. Are almost identical. Further, the protruding portion side inclined surface 134A of the protruding portion 134 in the upper connecting portion 130 of the rear carriage 110 and the opening side inclined surface 44B of the opening forming portion 44 in the lower connecting portion 40 of the front carriage 10 have a height. Are almost identical.

次に、後方の台車110を前方の台車10にさらに近付け、後方の台車110の上側連結部130における突出部134の突出部側傾斜面134Aを前方の台車10の下側連結部40における開口形成部44の開口側傾斜面44Bに接触させ、後方の台車110を前方の台車10にさらに近付けることで、突出部134の突出部側傾斜面134Aによって開口形成部44の開口側傾斜面44Bを押圧する。すると、開口形成部44の開口側傾斜面44Bと突出部134の突出部側傾斜面134Aとによって、突出部134が開口44側に向かって案内される。このとき、開口形成部44の開口側傾斜面44Bと突出部134の突出部側傾斜面134Aは、いずれも外側に膨らんだ曲面状とされているので、突出部134は開口44側に向かって滑らかに案内されることとなる。そして、突出部34が開口44A側に近づくにつれて、開口形成部44の開口側傾斜面44Bが突出部134によって下方に押圧され、下側連結部40が取付バネ52の弾性力に逆らって下方に回動する(図7の中段に示す状態)。   Next, the rear carriage 110 is further brought closer to the front carriage 10, and the protrusion-side inclined surface 134 </ b> A of the protrusion 134 in the upper connection section 130 of the rear carriage 110 is formed in the lower connection section 40 of the front carriage 10. The opening side inclined surface 44B of the opening forming portion 44 is pressed by the protruding portion side inclined surface 134A of the protruding portion 134 by contacting the opening side inclined surface 44B of the portion 44 and bringing the rear carriage 110 closer to the front carriage 10. To do. Then, the protruding portion 134 is guided toward the opening 44 by the opening-side inclined surface 44B of the opening forming portion 44 and the protruding-portion-side inclined surface 134A of the protruding portion 134. At this time, since the opening-side inclined surface 44B of the opening forming portion 44 and the protruding portion-side inclined surface 134A of the protruding portion 134 are both curved to bulge outward, the protruding portion 134 faces the opening 44 side. It will be guided smoothly. Then, as the protruding portion 34 approaches the opening 44A side, the opening-side inclined surface 44B of the opening forming portion 44 is pressed downward by the protruding portion 134, and the lower connecting portion 40 moves downward against the elastic force of the mounting spring 52. It rotates (state shown in the middle part of FIG. 7).

後方の台車110を前方の台車10にさらに近付けると、突出部134が開口44の上方まで進入し、突出部134の突出部側傾斜面134Aが開口形成部44の開口側傾斜面44Bから離間する。すると、開口形成部44の開口側傾斜面44Bを押圧していた力が無くなり、取付バネ52の弾性復帰力によって下側連結部40が元の状態、即ち、載置部42の上面42Aが荷台20の荷台面20Aと同一平面上に位置した状態に復帰する。これにより、突出部134が開口44内に挿入された状態となる(図7の下段に示す状態)。その結果、後方の台車110の上側連結部130における突出部134が前方の台車10の下側連結部40における開口44内の側面と前後方向において干渉することとなり、後方の台車110の上側連結部130が前方の台車10の下側連結部40と連結される。   When the rear carriage 110 is brought closer to the front carriage 10, the projecting portion 134 enters to above the opening 44, and the projecting portion side inclined surface 134 </ b> A of the projecting portion 134 is separated from the opening side inclined surface 44 </ b> B of the opening forming portion 44. . Then, the force pressing the opening-side inclined surface 44B of the opening forming portion 44 disappears, and the lower connecting portion 40 is in its original state by the elastic return force of the mounting spring 52, that is, the upper surface 42A of the mounting portion 42 is the loading platform. It returns to the state located on the same plane as 20 cargo bed surfaces 20A. As a result, the protruding portion 134 is inserted into the opening 44 (the state shown in the lower part of FIG. 7). As a result, the protrusion 134 in the upper coupling portion 130 of the rear carriage 110 interferes with the side surface in the opening 44 in the lower coupling section 40 of the front carriage 10 in the front-rear direction, and the upper coupling portion of the rear carriage 110 is 130 is connected to the lower connecting portion 40 of the front carriage 10.

次に、本実施形態の台車10と他の台車110との連結を解除する方法について説明する。前方の台車10と後方の台車110との連結を解除する際には、前方の台車10の下側連結部40の一部(例えば連結解除部46)を足のつま先等の下方へ押圧する。これにより、下側連結部40が取付バネ52の弾性力に逆らって下方に回動し、後方の台車110の上側連結部130における突出部134が前方の台車10の下側連結部40における開口44から外れた状態となる(図8に示す状態)。この状態において、後方の台車110を後方へ引くことにより、前方の台車10と後方の台車110との連結を解除することができる。   Next, a method for releasing the connection between the carriage 10 of this embodiment and the other carriage 110 will be described. When the connection between the front carriage 10 and the rear carriage 110 is released, a part of the lower connection portion 40 (for example, the connection release portion 46) of the front carriage 10 is pressed downward such as a toe of a foot. As a result, the lower connecting portion 40 rotates downward against the elastic force of the mounting spring 52, and the protruding portion 134 in the upper connecting portion 130 of the rear carriage 110 is opened in the lower connecting portion 40 of the front carriage 10. 44 (the state shown in FIG. 8). In this state, by pulling the rear carriage 110 rearward, the connection between the front carriage 10 and the rear carriage 110 can be released.

なお、上側連結部30の板状部32の上面32Aと下側連結部40の載置部42の上面42Aとはいずれも荷台20の荷台面20Aとほぼ同じ高さに位置するものとされているので、前方の台車に荷物60が載置され、図8に示すように、その荷物60の一部が前方の台車10の下側連結部40における載置部42の上面42A上にはみ出ている場合であっても、前方の台車10と後方の台車110との連結を解除することができる。この場合、下側連結部40において連結解除部46が載置部42の上面42Aよりも一段下がった構成とされているので、載置部42の上面42A上にはみ出た荷物60によって載置部42の上面42Aにおいて下方に押圧できる部位がなくても、連結解除部46を下方に押圧することができ、容易に連結を解除することができる。   Note that the upper surface 32A of the plate-like portion 32 of the upper connecting portion 30 and the upper surface 42A of the mounting portion 42 of the lower connecting portion 40 are both positioned at substantially the same height as the loading surface 20A of the loading platform 20. Therefore, the luggage 60 is placed on the front carriage, and as shown in FIG. 8, a part of the luggage 60 protrudes on the upper surface 42 </ b> A of the placement section 42 in the lower connecting portion 40 of the front carriage 10. Even if it exists, connection with the front trolley | bogie 10 and the back trolley | bogie 110 can be cancelled | released. In this case, in the lower connection portion 40, the connection release portion 46 is configured to be one step lower than the upper surface 42A of the placement portion 42, so that the placement portion is mounted by the luggage 60 protruding on the upper surface 42A of the placement portion 42. Even if there is no portion that can be pressed downward on the upper surface 42A of 42, the connection release portion 46 can be pressed downward, and the connection can be easily released.

また、同様に、前方の台車10に載置された荷物60の一部が前方の台車10の下側連結部40における載置部42の上面42A上にはみ出ている場合であっても、後方の台車110の上側連結部130における突出部134を前方の台車10の下側連結部40における開口44の上方まで進入させることができ、前方の台車10に対して後方から台車110を連結させることができる。   Similarly, even when a part of the luggage 60 placed on the front carriage 10 protrudes from the upper surface 42A of the placement section 42 in the lower connection part 40 of the front carriage 10, the rear The protruding portion 134 of the upper connecting portion 130 of the bogie 110 can be advanced to above the opening 44 of the lower connecting portion 40 of the front bogie 10, and the bogie 110 is connected to the front bogie 10 from the rear. Can do.

以上のように、本実施形態に係る台車10は、突出部30と開口形成部44の両方に突出部を開口へと案内する突出部側傾斜面34Aおよび開口側傾斜面44Bが設けられているので、一方の台車10と他方の台車とを連結させる際、他方の台車の上側連結部(下側連結部)を一方の台車10の下側連結部40(上側連結部30)に近付けるだけで、突出部30が突出部側傾斜面34Aおよび開口側傾斜面44Bによって開口44A側へと滑らかに案内され、突出部34と開口44Aとが凹凸嵌合される。このとき、上側連結部30の突出部34と下側連結部40の開口形成部44とが接触することで下側連結部40が下方へと押圧されて下側連結部40が下方に回動する。このため、一方の台車10または他方の台車を持ち上げることなく、上側連結部30と下側連結部40とを容易に連結させることができる。   As described above, the carriage 10 according to the present embodiment is provided with the protruding portion side inclined surface 34 </ b> A and the opening side inclined surface 44 </ b> B that guide the protruding portion to the opening in both the protruding portion 30 and the opening forming portion 44. Therefore, when one cart 10 and the other cart are connected, only the upper coupling portion (lower coupling portion) of the other cart is brought close to the lower coupling portion 40 (upper coupling portion 30) of the one cart 10. The protrusion 30 is smoothly guided to the opening 44A side by the protrusion-side inclined surface 34A and the opening-side inclined surface 44B, and the protrusion 34 and the opening 44A are unevenly fitted. At this time, the protrusion 34 of the upper connecting portion 30 and the opening forming portion 44 of the lower connecting portion 40 come into contact with each other, so that the lower connecting portion 40 is pressed downward, and the lower connecting portion 40 rotates downward. To do. For this reason, the upper side connection part 30 and the lower side connection part 40 can be easily connected, without lifting up the one trolley | bogie 10 or the other trolley | bogie.

また、下側連結部40を下方に押圧するだけで、下側連結部40が下方に回動して突出部34が開口44Aから外れるため、突出部34または開口形成部44に直接触れることなく、上側連結部30と下側連結部40との連結を解除することができる。さらに、上側連結部30と下側連結部40はいずれも荷台面20Aの高さよりも上方に越えない高さに設けられているため、上側連結部30および下側連結部40の上方に荷物60の一部がはみ出した状態で荷台面20Aに荷物を載せることができる。この状態において、下側連結部40を下方に回動することで、上側連結部30と下側連結部40の連結および連結解除を行うことができる。以上のように、本実施形態の台車10は、他の台車と容易に連結および連結解除することができ、連結部の上方に荷物60の一部がはみ出した状態であっても連結および連結解除することができる。   Further, by simply pressing the lower connecting portion 40 downward, the lower connecting portion 40 rotates downward and the protruding portion 34 is detached from the opening 44A, so that the protruding portion 34 or the opening forming portion 44 is not directly touched. The connection between the upper connection part 30 and the lower connection part 40 can be released. Further, since both the upper connecting portion 30 and the lower connecting portion 40 are provided at a height that does not exceed the height of the loading platform surface 20A, the luggage 60 is located above the upper connecting portion 30 and the lower connecting portion 40. The baggage can be placed on the loading platform surface 20A in a state where a part of the bag protrudes. In this state, the upper connecting portion 30 and the lower connecting portion 40 can be connected and disconnected by rotating the lower connecting portion 40 downward. As described above, the cart 10 according to the present embodiment can be easily connected and disconnected with other carts, and can be connected and disconnected even when a part of the luggage 60 protrudes above the connecting portion. can do.

また、本実施形態に係る台車10では、突出部34が、荷台面20Aに対して荷台20の内側から外側に向かって上方に傾斜する突出部側傾斜面34Aを有している。そして、開口形成部44が、荷台面20Aに対して荷台20の内側から外側に向かって下方に傾斜する開口側傾斜面44Bを有している。さらに、突出部34と凹凸嵌合されるときに突出部側傾斜面34Aと開口側傾斜面44Bとが接触するものとされ、突出部側傾斜面34Aと開口側傾斜面44Bの両方が外側に膨らんだ曲面状とされている。このような構成とされていることで、突出部34を開口44A内へと案内させる際に、突出部側傾斜面34Aと開口側傾斜面44Bとによって突出部34が開口44A側へと一層滑らかに案内されることとなるため、上側連結部30と下側連結部40とを一層連結させ易いものとすることができ、作業性を向上させることができる。   Moreover, in the trolley | bogie 10 which concerns on this embodiment, the protrusion part 34 has 34 A of protrusion part side inclined surfaces which incline upward toward the outer side from the inner side of the carrier 20 with respect to the carrier surface 20A. And the opening formation part 44 has the opening side inclined surface 44B which inclines below toward the outer side from the inner side of the loading platform 20 with respect to the loading platform surface 20A. Furthermore, when the protrusion 34 is engaged with the protrusion 34, the protrusion-side inclined surface 34A and the opening-side inclined surface 44B are in contact with each other, and both the protrusion-side inclined surface 34A and the opening-side inclined surface 44B are on the outside. It is a bulging curved surface. With this configuration, when the protrusion 34 is guided into the opening 44A, the protrusion 34 is more smoothly moved toward the opening 44A due to the protrusion-side inclined surface 34A and the opening-side inclined surface 44B. Therefore, the upper connecting portion 30 and the lower connecting portion 40 can be more easily connected, and workability can be improved.

また、本実施形態に係る台車10では、下側連結部40が、下側連結部40の左右両端部において荷台面20Aの高さより下方に設けられた連結解除部46をそれぞれ有している。ここで、荷台面20Aに載置された荷物60の一部が下側連結部40の上方にはみ出ている場合、荷物60が邪魔となって下側連結部40を下方に押圧し難くなる虞がある。本実施形態によると、下側連結部40が下側連結部40の左右両端部において荷台面20Aの高さより下方に設けられた連結解除部46をそれぞれ有しているため、荷台面20Aに載置された荷物60の一部が下側連結部40の上方にはみ出ている場合であっても、連結解除部46を下方に押圧することで、荷物60が邪魔となることなく、下側連結部40を下方に回動させることができ、作業性を向上させることができる。   Moreover, in the trolley | bogie 10 which concerns on this embodiment, the lower side connection part 40 has the connection cancellation | release part 46 provided below from the height of the loading platform surface 20A in the right-and-left both ends of the lower side connection part 40, respectively. Here, when a part of the load 60 placed on the loading platform surface 20A protrudes above the lower connection portion 40, the load 60 may be in the way, making it difficult to press the lower connection portion 40 downward. There is. According to the present embodiment, since the lower connecting portion 40 has the connection release portions 46 provided below the height of the loading platform surface 20A at the left and right ends of the lower coupling portion 40, the lower coupling portion 40 is mounted on the loading platform surface 20A. Even when a part of the placed luggage 60 protrudes above the lower connection part 40, the connection release part 46 is pressed downward so that the luggage 60 does not get in the way. The part 40 can be rotated downward, and workability can be improved.

また、本実施形態に係る台車10では、一方の側面に側面ローラ54が設けられているため、前後方向および左右方向に隙間なく同じ向きで複数の台車が並べられた場合、複数の台車の中から所望の台車を取り出す際に、左右方向に隣り合う台車同士は側面ローラ54と側面ローラ54が設けられていない他方の側面とが接触することで相対的に円滑に移動可能とされている。台車10の両側に側面ローラ54が取り付けられている場合には、側面ローラ54同士が干渉し合うため、両者の相対的な移動の際にがたつきが生じて作業が困難となるが、本実施形態の台車10は、がたつくことなく小さな力で相対移動させることができるため、作業性を向上させることができる。   Further, in the cart 10 according to the present embodiment, the side roller 54 is provided on one side surface. Therefore, when a plurality of carts are arranged in the same direction without gaps in the front-rear direction and the left-right direction, When the desired cart is taken out from the cart, the carts adjacent in the left-right direction can move relatively smoothly by contacting the side roller 54 and the other side surface where the side roller 54 is not provided. When the side rollers 54 are attached to both sides of the carriage 10, the side rollers 54 interfere with each other, so that the relative movement of the two causes rattling and the work becomes difficult. Since the cart 10 of the embodiment can be relatively moved with a small force without rattling, workability can be improved.
