以下、本発明の実施形態を図１〜図９ に基づいて説明する。図１には、２台のフレーム台車１０，１０が隣り合わせに並んだ状態が示されている。各フレーム台車１０は、アルミ製の長短１対ずつのアングル材１１を樹脂製のコーナーベース１３で結合してなる。コーナーベース１３は、台座部１５の上面から側壁１６が起立した構造をなしている。台座部１５は、平面形状が概ね直角二等辺三角形の鋭角の両角部をカットした形状をなし、下面にはキャスター１４が取り付けられている。側壁１６は、台座部１５の直角の角部を挟んだ２辺の外縁部から起立している。また、側壁１６の両端部は、二重壁構造をなし、台座部１５の上面のうち側壁１６の両端部の近傍には、長方形の陥没部１５Ａが形成されている。そして、各アングル材１１のうち断面Ｌ字の横辺部分が陥没部１５Ａに収められ、縦辺部分が、側壁１６の二重壁部分の隙間に挿入された状態に固定されている。これにより、アングル材１１の横辺部分の上面と台座部１５の上面とから荷物載置面１７が形成されると共に、アングル材１１の縦辺部分と側壁１６とから枠状の嵌合側壁１８が形成されている。 Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 9. FIG. 1 shows a state in which two frame carts 10 and 10 are arranged side by side. Each frame carriage 10 is formed by connecting a pair of long and short angle members 11 made of aluminum with a corner base 13 made of resin. The corner base 13 has a structure in which the side wall 16 stands up from the upper surface of the pedestal portion 15. The pedestal portion 15 has a shape in which both corner portions having an acute angle of an isosceles right triangle having a plane shape are cut, and casters 14 are attached to the lower surface thereof. The side wall 16 stands up from the outer edge portion of two sides sandwiching the right-angled corner portion of the pedestal portion 15. Further, both ends of the side wall 16 have a double wall structure, and a rectangular recessed portion 15A is formed in the vicinity of both ends of the side wall 16 on the upper surface of the pedestal portion 15. The horizontal side portion of each angle member 11 having an L-shaped cross section is housed in the depressed portion 15A, and the vertical side portion is fixed in a state of being inserted into the gap of the double wall portion of the side wall 16. As a result, the luggage loading surface 17 is formed from the upper surface of the lateral side portion of the angle member 11 and the upper surface of the pedestal portion 15, and the frame-shaped fitting side wall 18 is formed from the vertical side portion of the angle member 11 and the side wall 16. Is formed.

上記したフレーム台車１０，１０同士を連結するための台車ジョイント２０が図２（Ａ）及び図２（Ｂ）に示されている。台車ジョイント２０は、樹脂の射出成形品であって、下面が開口したＴ字状の溝形構造をなし、上面に持ち手部２３を備えている。詳細には、台車ジョイント２０は、Ｔ形天板３３を有し、Ｔ形天板３３のＴ字の縦辺に相当する第１帯板部３１と、その両側縁部から垂下された１対の第１側壁３４，３４とから第１溝部２１が構成されている。また、Ｔ形天板３３のＴ字の横辺に相当する第２帯板部３２と、その一方の側縁部から垂下された１対の第２側壁３５，３５と、他方の側縁部から垂下された第３側壁３６とから第２溝部２２が構成されている。さらに、１対の第１側壁３４，３４と１対の第２側壁３５，３５とは、直交した状態に接続されて左右対称の１対のＬ形側壁３７，３７を構成している。 The carriage joint 20 for connecting the frame carriages 10 and 10 described above is shown in FIGS. 2 (A) and 2 (B). The bogie joint 20 is a resin injection-molded product, has a T-shaped groove structure with an open lower surface, and has a handle portion 23 on the upper surface. Specifically, the bogie joint 20 has a T-shaped top plate 33, a first strip portion 31 corresponding to the vertical side of the T-shape of the T-shaped top plate 33, and a pair hanging from both side edges thereof. The first groove portion 21 is configured from the first side wall 34, 34 of the above. Further, a second strip portion 32 corresponding to the side surface of the T-shape of the T-shaped top plate 33, a pair of second side walls 35 and 35 hanging from one side edge portion thereof, and the other side edge portion. The second groove portion 22 is configured from the third side wall 36 suspended from the third side wall 36. Further, the pair of first side walls 34, 34 and the pair of second side walls 35, 35 are connected in an orthogonal state to form a pair of symmetrical L-shaped side walls 37, 37.

また、第１側壁３４と第２側壁３５の下面は面一で、それらの下面より第３側壁３６の下面が僅かに下方に位置している。さらに、第１溝部２１の先端下側角部（即ち、第１側壁３４，３４の先端角部）は面取りされて、半円形の面取部３４Ａ，３４Ａになっている。その第１側壁３４の曲率半径は、第１側壁３４の高さの略半分になっている。なお、第２側壁３５の先端角部は、面取部３４Ａより小さい曲率半径で面取りされ、さらにそれより小さい曲率半径で第３側壁３６の先端角部が面取りされている。 Further, the lower surfaces of the first side wall 34 and the second side wall 35 are flush with each other, and the lower surface of the third side wall 36 is located slightly below the lower surfaces thereof. Further, the lower tip lower corner portion of the first groove portion 21 (that is, the tip corner portion of the first side wall 34, 34) is chamfered to form a semicircular chamfered portion 34A, 34A. The radius of curvature of the first side wall 34 is approximately half the height of the first side wall 34. The tip corner portion of the second side wall 35 is chamfered with a radius of curvature smaller than that of the chamfered portion 34A, and the tip corner portion of the third side wall 36 is chamfered with a radius of curvature smaller than that.

Ｌ形側壁３７の内面には、横方向の複数位置に縦長の寄せリブ３８が形成されている。寄せリブ３８のうち上下方向の途中位置より下側は、摺接部３８Ｇになっていて、下方に向かうに従ってＬ形側壁３７からの突出量が徐々に小さくなっている。一方、寄せリブ３８のうち摺接部３８Ｇより上側の当接部３８Ａは、Ｌ形側壁３７からの突出量が略均一になっている。 On the inner surface of the L-shaped side wall 37, vertically long gathering ribs 38 are formed at a plurality of positions in the lateral direction. The lower side of the pulling rib 38 below the intermediate position in the vertical direction is the sliding contact portion 38G, and the amount of protrusion from the L-shaped side wall 37 gradually decreases toward the lower side. On the other hand, the contact portion 38A above the sliding contact portion 38G of the close-up ribs 38 has a substantially uniform amount of protrusion from the L-shaped side wall 37.

図３に示すように、第２溝部２２の実質的な溝幅である第２側壁３５と寄せリブ３８の当接部３８Ａとの間隔は、フレーム台車１０の嵌合側壁１８のコーナー近傍部分（即ち、側壁１６）の厚さと同一かそれより僅かに大きくなっている。つまり、第２溝部２２は、１つの嵌合側壁１８が丁度受容可能な溝幅になっている。一方、第１溝部２１の溝幅である第１側壁３４，３４の内面同士の間隔は、嵌合側壁１８のコーナー近傍部分（即ち、側壁１６）の２枚分の厚さと同一かそれより僅かに大きくなっている。つまり、第２溝部２２は、嵌合側壁１８を２枚重ねにして丁度受容可能な溝幅をなしている。 As shown in FIG. 3, the distance between the second side wall 35, which is the substantially groove width of the second groove portion 22, and the contact portion 38A of the gathering rib 38 is the portion near the corner of the fitting side wall 18 of the frame carriage 10. That is, it is the same as or slightly larger than the thickness of the side wall 16). That is, the second groove portion 22 has a groove width that can be just accepted by one fitting side wall 18. On the other hand, the distance between the inner surfaces of the first side walls 34, 34, which is the groove width of the first groove portion 21, is the same as or slightly smaller than the thickness of two pieces of the fitting side wall 18 near the corner (that is, the side wall 16). It is getting bigger. That is, the second groove portion 22 has a groove width that can be just received by stacking two fitting side walls 18 on top of each other.

図２（Ａ）に示すように、持ち手部２３は、第１帯板部３１の長手方向の略中央位置と、第２帯板部３２の第３側壁３６側の側縁位置との２位置にアーチ状に架け渡され、内側が指挿入孔２３Ａになっている。詳細には、持ち手部２３は、第１帯板部３１より僅かに幅狭の帯板状をなして、第２帯板部３２の第３側壁３６側の側縁位置から真上に立ち上がり、そこから第１帯板部３１側に円弧状に湾曲し、第１帯板部３１の長手方向の略中央の上方位置に向かって斜め下方に真っ直ぐ延びてから湾曲して真下に向かい、第１帯板部３１に接続されている。これにより、例えば、持ち手部２３の下方に人差指を通して台車ジョイント２０を持ち上げると、第１溝部２１が第２溝部２２から斜め下方に延びた傾斜姿勢になる。
なお、図４に示すように、持ち手部２３のうち第２帯板部３２から真上に立ち上がった部分の外面は、第３側壁３６の外面と面一になっている。 As shown in FIG. 2A, the handle portion 23 has a substantially central position in the longitudinal direction of the first strip portion 31 and a side edge position of the second strip portion 32 on the third side wall 36 side. It is laid in an arch shape at the position, and the inside is a finger insertion hole 23A. Specifically, the handle portion 23 has a strip shape slightly narrower than that of the first strip portion 31 and rises directly above from the side edge position of the second strip portion 32 on the third side wall 36 side. From there, it curves in an arc shape toward the first strip 31 side, extends diagonally downward toward the upper position of the substantially center in the longitudinal direction of the first strip 31, then curves and heads straight down. 1 It is connected to the strip portion 31. As a result, for example, when the bogie joint 20 is lifted by passing the index finger below the handle portion 23, the first groove portion 21 becomes an inclined posture extending diagonally downward from the second groove portion 22.
As shown in FIG. 4, the outer surface of the portion of the handle portion 23 that rises directly above the second strip portion 32 is flush with the outer surface of the third side wall 36.

本実施形態の台車ジョイント２０の構成に関する説明は以上である。次に、この台車ジョイント２０の作用効果について説明する。台車ジョイント２０を使用して２台のフレーム台車１０，１０を連結するには、図１に示すように、フレーム台車１０，１０を隣り合わせに並べて、両嵌合側壁１８，１８のコーナー部の一辺同士が重なりかつそれらの隣の辺同士が一直線状に並んだＴ形側壁部１９が形成されるようにする。なお、図５に示すように、Ｔ形側壁部１９の縦辺部分１９Ａでは、嵌合側壁１８，１８を構成する側壁１６，１６同士とその下方の台座部１５，１５同士が共に当接した状態になる。 This concludes the description of the configuration of the bogie joint 20 of the present embodiment. Next, the action and effect of the bogie joint 20 will be described. In order to connect the two frame carriages 10 and 10 using the carriage joint 20, as shown in FIG. 1, the frame carriages 10 and 10 are arranged side by side and one side of the corner portion of both fitting side walls 18 and 18 is arranged side by side. A T-shaped side wall portion 19 is formed in which the sides overlap each other and the sides adjacent to them are aligned in a straight line. As shown in FIG. 5, in the vertical side portion 19A of the T-shaped side wall portion 19, the side walls 16 and 16 constituting the fitting side walls 18 and 18 and the pedestal portions 15 and 15 below the side walls 16 and 16 are in contact with each other. Become a state.

台車ジョイント２０をフレーム台車１０，１０に装着するには、例えば、持ち手部２３の指挿入孔２３Ａに指を通して台車ジョイント２０を持ち上げ、図６に示すように、台車ジョイント２０を第１溝部２１側が下がった傾斜姿勢にして、第１溝部２１の先端部をＴ形側壁部１９の縦辺部分１９Ａに嵌合させる。そして、第１溝部２１の先端部を中心にして第２溝部２２側を下げるように回動させる。すると、Ｔ形側壁部１９の横辺部分１９Ｂが第３側壁３６の摺接部３８Ｇと摺接して第２溝部２２内に案内される。 To attach the trolley joint 20 to the frame trolleys 10 and 10, for example, the trolley joint 20 is lifted by passing a finger through the finger insertion hole 23A of the handle portion 23, and the trolley joint 20 is attached to the first groove portion 21 as shown in FIG. The tip portion of the first groove portion 21 is fitted to the vertical side portion 19A of the T-shaped side wall portion 19 in an inclined posture with the side lowered. Then, it is rotated so as to lower the second groove 22 side around the tip of the first groove 21. Then, the lateral side portion 19B of the T-shaped side wall portion 19 is in sliding contact with the sliding contact portion 38G of the third side wall 36 and is guided into the second groove portion 22.

このとき、第１溝部２１の先端下側角部は、フレーム台車１０の荷物載置面１７に接近するが、第１溝部２１の先端下側角部は面取部３４Ａになっているので荷物載置面１７との干渉が避けられ、仮に荷物載置面１７に当接しても面取部３４Ａは円弧状になっているのでスムーズに回転する。また、第２溝部２２のうち寄せリブ３８を有する側の第３側壁３６は、その反対側の第２側壁３５より下方に突出しているので、台車ジョイント２０を回動してＴ形側壁部１９の横辺部分１９Ｂをスムーズに第２溝部２２に嵌合させることができる。そして、台車ジョイント２０が水平姿勢になるまで回動させると、図３に示すように、第１溝部２１全体がＴ形側壁部１９の縦辺部分１９Ａに嵌合しかつ、第２溝部２２全体がＴ形側壁部１９の横辺部分１９Ｂに嵌合した状態になって、台車ジョイント２０の装着作業が完了する。 At this time, the lower tip corner portion of the first groove portion 21 approaches the luggage loading surface 17 of the frame carriage 10, but the lower tip lower corner portion of the first groove portion 21 is a chamfered portion 34A, so that the luggage is loaded. Interference with the mounting surface 17 is avoided, and even if it comes into contact with the loading surface 17, the chamfered portion 34A has an arc shape and therefore rotates smoothly. Further, since the third side wall 36 on the side of the second groove portion 22 having the gathering rib 38 projects downward from the second side wall 35 on the opposite side, the carriage joint 20 is rotated to rotate the T-shaped side wall portion 19. The lateral side portion 19B of the above can be smoothly fitted to the second groove portion 22. Then, when the bogie joint 20 is rotated until it is in a horizontal posture, as shown in FIG. 3, the entire first groove portion 21 fits into the vertical side portion 19A of the T-shaped side wall portion 19, and the entire second groove portion 22 is formed. Is fitted to the horizontal side portion 19B of the T-shaped side wall portion 19, and the mounting work of the bogie joint 20 is completed.

そして、連結する対象のフレーム台車１０が２台の場合には、図７に示すように２箇所のＴ形側壁部１９に台車ジョイント２０をそれぞれ装着すればよい。また、図９に示すように４台のフレーム台車１０を縦横に２行２列に並べた状態に連結するには、それらフレーム台車１０群の外縁側の４箇所に形成されるＴ形側壁部１９に台車ジョイント２０をそれぞれ装着すればよい。 When there are two frame carriages 10 to be connected, the carriage joints 20 may be attached to the two T-shaped side wall portions 19 as shown in FIG. 7. Further, as shown in FIG. 9, in order to connect the four frame carriages 10 in a state of arranging them vertically and horizontally in two rows and two columns, T-shaped side wall portions formed at four locations on the outer edge side of the frame carriages 10 group are formed. The bogie joint 20 may be attached to each of 19.

上記したように本実施形態の台車ジョイント２０では、図７に示すように、嵌合側壁１８，１８のコーナー部同士が隣り合わせになって形成されるＴ形側壁部１９の縦辺部分１９Ａと横辺部分１９Ｂとに第１溝部２１と第２溝部２２とがそれぞれ嵌合される。これにより、フレーム台車１０，１０同士が並ぶ方向とそれに直交する方向との両方向でフレーム台車１０，１０同士がずれないように連結され、従来より連結状態が安定する。また、台車ジョイント２０，２０が装着されるＴ形側壁部１９，１９は、フレーム台車１０，１０の外縁に位置しているので、図８に示すように、両フレーム台車１０，１０に箱形荷物９０，９０が搭載されていても、台車ジョイント２０，２０をフレーム台車１０，１０に容易に着脱することができる。 As described above, in the bogie joint 20 of the present embodiment, as shown in FIG. 7, the corner portions of the fitting side walls 18 and 18 are formed side by side with the vertical side portion 19A of the T-shaped side wall portion 19 and laterally. The first groove portion 21 and the second groove portion 22 are fitted to the side portion 19B, respectively. As a result, the frame carriages 10 and 10 are connected so as not to be displaced in both directions of the direction in which the frame carriages 10 and 10 are lined up and the direction orthogonal to the arrangement, and the connected state is more stable than before. Further, since the T-shaped side wall portions 19 and 19 on which the bogie joints 20 and 20 are mounted are located on the outer edges of the frame bogies 10 and 10, as shown in FIG. 8, both frame bogies 10 and 10 have a box shape. Even if the luggage 90, 90 is mounted, the bogie joints 20 and 20 can be easily attached to and detached from the frame bogies 10 and 10.

また、台車ジョイント２０に持ち手部２３が備えられていることによってもフレーム台車１０，１０への着脱操作を容易に行うことができる。しかも、持ち手部２３には指挿入孔２３Ａが備えられているので、そこに指を通すことで指を滑らせることなく着脱作業を行うことができる。また、持ち手部２３は、図４及び図８に示すように、第２溝部２２から第１溝部２１の反対側に突出していないので、連結されたフレーム台車１０群の側面からの持ち手部２３の張り出し量が抑えられ、フレーム台車１０群の走行中に持ち手部２３が異物に当接して破損したり、台車ジョイント２０がフレーム台車１０，１０から外れるような事態を回避することができる。さらに、図２に示すように、台車ジョイント２０はＴ形天板３３と１対のＬ形側壁３７，３７とを有して第１溝部２１と第２溝部２２とが一体になっているので、強度が高く、この点においてもフレーム台車１０，１０同士の連結状態が安定する。 Further, since the bogie joint 20 is provided with the handle portion 23, the operation of attaching / detaching to / from the frame bogies 10 and 10 can be easily performed. Moreover, since the handle portion 23 is provided with a finger insertion hole 23A, the attachment / detachment work can be performed without slipping the finger by passing the finger through the hole 23A. Further, as shown in FIGS. 4 and 8, the handle portion 23 does not project from the second groove portion 22 to the opposite side of the first groove portion 21, so that the handle portion 23 is a handle portion from the side surface of the connected frame carriages 10 group. The amount of protrusion of the 23 is suppressed, and it is possible to avoid a situation in which the handle portion 23 comes into contact with a foreign object and is damaged while the frame carriage 10 group is traveling, or the carriage joint 20 is detached from the frame carriages 10 and 10. .. Further, as shown in FIG. 2, since the bogie joint 20 has a T-shaped top plate 33 and a pair of L-shaped side walls 37, 37, the first groove portion 21 and the second groove portion 22 are integrated. The strength is high, and the connected state of the frame carriages 10 and 10 is stable in this respect as well.

なお、台車ジョイント２０は、フレーム台車１０と異なる色になっていて、これによりフレーム台車１０に対する台車ジョイント２０の装着の有無を容易に確認することができる。 The bogie joint 20 has a different color from that of the frame bogie 10, so that it is possible to easily confirm whether or not the bogie joint 20 is attached to the frame bogie 10.
