【産業上の利用分野】[Industrial applications]

本考案は折畳み棚枠付の台車に関し、多段の棚枠を折畳むとき棚枠支持の一方 の支持柱が固定柱に向け移動する上記台車に関する。 The present invention relates to a trolley with a folding shelf frame, and relates to the trolley in which one support column of the shelf frame support moves toward a fixed column when folding a multi-tiered shelf frame.

【０００２】[0002]

【従来の技術】[Prior art]

従来から多段に棚板を備えた台車は周知である。棚板は固着式のもの着脱自在 のものとがあるが、棚板を載せてある棚枠は一般的に固定のものが多い。 BACKGROUND ART Conventionally, a trolley having a plurality of shelves is well known. There are fixed type and removable type shelf boards, but the shelf frames on which shelf boards are mounted are generally fixed.

【０００３】 多段の棚枠では棚枠間の間隔を拡げたり狭めたりするため、取外しうるものも あって、これによって台車の内側の突出部をなくして、拡がった内側に台車を並 べてコンパクトに多数保管するものもある。 然しながら取外して別の場所に保管した棚枠はその取扱いが雑になり、紛失した りすること等もあって次回に取付けるのに煩らわしさが残る。In a multi-tiered shelf frame, the space between the shelf frames is widened or narrowed, so that some racks can be removed, which eliminates the protrusions on the inside of the carriage and allows the carriages to be arranged side by side in a compact manner. Some are stored in large numbers. However, the shelf frame that has been removed and stored in a different place is not easy to handle because it is mishandled and lost.

【０００４】[0004]

【考案が解決しようとする課題】[Problems to be solved by the device]

従来のこの種の棚枠付の台車は棚枠が台車のベースを剛性安定にした状態で棚 枠を折畳むことができないので、台車の外周で囲む容積を小さくすることができ ない。それで台車を所定の場所に多数収容することが不可である。 In the conventional bogie with this kind of shelf frame, the shelf frame cannot be folded in a state where the shelf frame stabilizes the rigidity of the base of the bogie, so the volume enclosed by the outer periphery of the bogie cannot be reduced. Therefore, it is impossible to accommodate a large number of trucks in a predetermined place.

【０００５】[0005]

【課題を解決するための手段】[Means for Solving the Problems]

本考案は上記諸問題を解決するためなされ、使用時には棚枠を拡げ、不使用時 には棚枠を折畳むことのできる台車であって、その間台車のベースは常に剛性安 定を保ちつつベース上で棚枠を取囲む容積を使用状態の拡大姿から、不使用状態 の縮少姿に変化しうる台車である。 The present invention has been made to solve the above problems, and is a trolley capable of expanding the shelf frame when in use and folding the shelf frame when not in use, during which the base of the trolley is always a stable base. It is a dolly that can change the volume that surrounds the shelf frame from the expanded state in use to a reduced size in the unused state.

【０００６】 その要点を述べれば長方形状平行に配され長さ方向両端にキャスター付の一対 の基礎レールと、該レールを対角線的に結ぶ一本の剛性梁と、該基礎レールの同 方向一端に夫々固定した一対の固定柱と、該基礎レール上を固定柱に向け直立し て移動し固定柱と組となる一対の可動柱と、各段向合った内端が夫々相互に枢支 され、腹部が組となる固定柱と可動柱に夫々枢支されたコ字状外形のある一対の 単位枠の棚枠からなる複数段の棚枠を具えていて、前記一方の基礎レール側の複 数段の棚枠の相互に枢支された各内端は前記レールに垂直な一本の縦棒で枢支さ れた構造の台車が供される。この台車では縦棒の上下動で複数段の棚枠が相互連 動して展開並びに垂直折畳みうるようになっている。In summary, a pair of base rails, which are arranged in parallel in a rectangular shape and have casters at both ends in the longitudinal direction, a rigid beam connecting the rails diagonally, and one end of the base rail in the same direction. A pair of fixed pillars fixed to each other, a pair of movable pillars that move upright on the foundation rail toward the fixed pillars to form a pair with the fixed pillars, and inner ends facing each other are pivoted to each other, It comprises a multi-tiered shelf frame consisting of a pair of unit frames with a U-shaped outer shape pivoted on a fixed column and a movable column, each of which forms a pair of abdominal parts. A carriage having a structure in which each inner end of the stepped shelf frame which is pivotally supported to each other is pivotally supported by one vertical bar perpendicular to the rail is provided. In this dolly, the vertical movements of the vertical bars allow the racks in multiple stages to move in unison so that they can be unfolded and vertically folded.

FIG. 1 is a perspective view showing a usage state of the dolly of the present invention, FIG. 2 is a perspective view in the middle of folding, FIG. 3 is a perspective view showing a folded state, and FIG. 4 is a side view in which two dollies are arranged in a housed state. FIG. 5 is a plan view showing the base portion of the trucks arranged side by side, and FIG. 6 is a perspective view showing the upper portion of the pillar of the lower carriage and the pillar receiving portion of the upper carriage when the carriages are stacked.

【０００８】 本考案のベースは長方形状平行に配した一対の基礎レール１と２と、このレー ルを対角線的に結ぶ剛性梁３からなっている。各レールにはその両端近くにキャ スター４，５が回転可能に取付けてある。レール１の図面上右端には固定柱６が 立設され、左側には可動柱７が設けられている。可動柱はレール１に図示しない 凹設せる摺接レール上を柱の底が摺動して固定柱に向け移動できるようになって いる。レール２においても固定柱８と可動柱９とがレール１のものと同一構造で 設けられている。The base of the present invention comprises a pair of base rails 1 and 2 arranged in parallel in a rectangular shape, and a rigid beam 3 connecting the rails diagonally. Casters 4 and 5 are rotatably attached to both ends of each rail. A fixed column 6 is erected on the right end of the rail 1 in the drawing, and a movable column 7 is provided on the left side. The movable column is designed so that the bottom of the column slides on a sliding contact rail (not shown) which is provided in the rail 1 so as to move toward the fixed column. Also in the rail 2, the fixed column 8 and the movable column 9 are provided with the same structure as that of the rail 1.

【０００９】 固定柱６，８間と可動柱７，９間は上部に梁１０，１１が固定されている。固 定柱と可動柱の間には棚枠１３，１４，１５，１６が設けられている。棚枠の構 造は何れも実質的同じであるので、その一例を棚枠１３について述べる。棚枠は コ字状の２個の枠１７，１８からなり、その内端１９，２０は互に突当って枢支 されている。両コ字状枠の腹部２１，２２は角部２３，２４，２５，２６で固定 柱と可動柱に夫々枢支される。棚枠１３乃至１６のレール１にある両方のリンク の１９で代表される枢着した片側４個の内端のみは一本の縦棒３０で枢支されて いる。図面上３１，３２は夫々レールの端に設けられた下向の受碗で可動柱と固 定柱の先端３３，３４を受入れるようになっている。Beams 10 and 11 are fixed to the upper portions between the fixed columns 6 and 8 and between the movable columns 7 and 9. Shelf frames 13, 14, 15, 16 are provided between the fixed column and the movable column. Since the structure of the shelf frame is substantially the same, an example thereof will be described for the shelf frame 13. The shelf frame is composed of two U-shaped frames 17 and 18, the inner ends 19 and 20 of which are abutted and pivotally supported. The belly portions 21 and 22 of the U-shaped frame are pivotally supported by the fixed columns and the movable columns at the corners 23, 24, 25 and 26, respectively. Only the four inner ends of one of the links, represented by 19, of both links on the rails 1 of the shelves 13 to 16 are pivotally supported by a single vertical bar 30. In the drawing, reference numerals 31 and 32 are downward bowls provided at the ends of the rails, respectively, so as to receive the tips 33 and 34 of the movable column and the fixed column.

【００１０】 本考案は以上のようになっていて図１のように固定柱に対して可動柱を離すと 棚枠のリンクは伸びる。この状態で棚枠１３…の夫々にわたって棚板を、又は長 尺物を渡すことができる。縦棒３０を上方に押上げると、１９で代表される各棚 枠の一方の枢支点と、柱に取付けられている２３，２４，２５，２６で代表され る各枢支点と、２０で代表される各棚枠の他方の枢支点は枢動しつつ、腹部２１ ，２２、コ字上枠１７，１８を含め図面上４個の棚枠１３，１４，１５，１６は 図２のように連動して内端１９，２０を頂点とした三角状になる。これに伴って 可動柱７，９はレール上を固定柱６，８に向け移動し始め、図３で示す位置まで 移動して止る。かくして棚枠が折畳まれる。The present invention is as described above, and the link of the shelf frame extends when the movable column is separated from the fixed column as shown in FIG. In this state, a shelf board or a long object can be passed over each of the shelf frames 13 ... When the vertical bar 30 is pushed upward, one pivotal fulcrum of each shelf frame represented by 19 and each pivotal fulcrum represented by 23, 24, 25, and 26 attached to the pillar are represented by 20. While the other pivot point of each shelf frame is pivoted, the four shelf frames 13, 14, 15, 16 including the abdomen 21, 22 and the U-shaped frame 17, 18 are as shown in FIG. The inner ends 19 and 20 are interlocked with each other to form a triangular shape. Along with this, the movable columns 7 and 9 start moving on the rail toward the fixed columns 6 and 8, and move to the position shown in FIG. 3 and stop. Thus, the shelf frame is folded.

【００１１】 このように折畳まれた状態に対し折畳んだ第２の台車を近付けると第２台車の 一方の基礎レール１ａと剛性梁３ａは第１台車の一方の基礎レール１と剛性染３ で囲む角内に収まり、第２台車の他方の基礎レール２ａは第１台車の他方の基礎 レール２の外側に並ぶようにして収容することができる。従って棚枠を外さず折 畳んだ状態で限られた面積内に多数の台車を収容することができる。When the folded second truck is brought closer to the folded state as described above, one of the base rails 1a and the rigid beams 3a of the second truck is fixed to the one of the first rail 1 and the rigid dye 3 of the first truck. The second base rail 2a of the second carriage can be accommodated in the corner surrounded by the so as to be lined up outside the other base rail 2 of the first carriage. Therefore, a large number of carriages can be accommodated within a limited area in a folded state without removing the shelf frame.

【００１２】 次に各基礎レールの末端には下向の受碗３１，３２があるので、図１に示す使 用状態で下台車の柱６，７，８，９の頂３３，３４を碗３１，３２に受入れるこ とによって下の台車に上の台車を載せることができる。Next, since the bowls 31 and 32 facing downward are provided at the ends of the respective foundation rails, the tops 33 and 34 of the pillars 6, 7, 8, 9 of the lower carriage are bowled in the usage state shown in FIG. The upper carriage can be placed on the lower carriage by accepting 31 and 32.

【００１３】 更に本考案台車において固定柱と可動柱間に棚枠１３等を、例えば２３，２４ ，２５，２６の位置で枢着取付ける方法において、公知の方法で着脱自在に取付 けることもできる。この場合固定柱と可動柱の前記２３乃至２６の位置に棚枠の 腹部２１，２２の両端を支承するために上部に差込口のある支承用切欠を設け、 この切欠に前記腹部を差込んで棚枠１３等を枢支的に支承させることができる。 又継棒を枢支点１９で分離できるように複数の棒片からなるようにしておくとよ い。このようにすると棚枠の上下の間隔を拡げようとするときは一組の棚枠を取 外せばよく、又上下間隔が拡がっているときにはその間に他の棚枠を取付けるこ ともできる。Further, in the cart of the present invention, the shelf frame 13 or the like can be detachably attached by a known method in the method of pivotally attaching the shelf frame 13 and the like between the fixed column and the movable column at the positions of 23, 24, 25 and 26. . In this case, in order to support both ends of the abdominal portions 21 and 22 of the shelf frame at the positions 23 to 26 of the fixed column and the movable column, a supporting notch having an insertion opening is provided at the upper part, and the abdominal portion is inserted into this notch. It is possible to pivotally support the shelf frame 13 and the like. Also, it is recommended that the connecting rod be composed of a plurality of rod pieces so that they can be separated at the pivot point 19. In this way, one set of shelf frames can be removed when the upper and lower intervals of the shelf frames are to be expanded, and another shelf frame can be mounted between them when the upper and lower intervals are widened.

【考案の効果】[Effect of device]

以上述べたように本考案の台車は軽く縦棒を上動するか、可動柱を固定柱に向 け押動することで棚枠が折畳まれる。折畳んだ状態は各単位の棚枠は枕屏風を畳 んだと同じく極めて薄くなり台車の要部は極めて専有容積が小さくなる。又ベー スがＮ形となっているので、他の台車のベースを深く並べて受入れるので小面積 で台車を収納できる。 As described above, in the cart of the present invention, the shelf frame is folded by lightly moving the vertical bar upward or pushing the movable column toward the fixed column. In the folded state, the shelf frame of each unit is extremely thin as in the case of folding the folding screen, and the main portion of the trolley has a very small volume. In addition, since the base is N type, the bases of other trucks are deeply lined up and received, so the truck can be stored in a small area.
