Description

本発明は、簡易な構造で、待機位置において６０％の縮小が可能なネスティング効率が高い運搬用台車に関するものである。   The present invention relates to a transportation cart having a simple structure and high nesting efficiency capable of being reduced by 60% at a standby position.

従来、ネスティング可能な運搬用台車は、台板を撥ね上げて待機状態とする台車、あるいは台板を折畳み式とする台車など種々のものが提案されている。台板を撥ね上げて待機状態とする台車の場合、長さ方向の縮小ができないため、ネスティングを行うと、待機スペースをとってしまうという問題がある。折畳み式台板を備える台車としては、特開平１１−４３０４７号公報あるいは特開２００３−５４４１２号公報に開示されているが、特開平１１−４３０４７号公報記載の運搬用台車は、台車を折畳んで組み立てする場合、正面枠と案内枠との間の摩擦抵抗等によって、正面枠が案内枠に対して円滑に前後移動しないという問題がある。また、特開２００３−５４４１２号公報記載の運搬用台車は、正面枠が案内枠に対して円滑に前後移動するものの、構造が複雑であり、部品点数が多い分、故障確率も高くコストを抑制できないという問題がある。
特開平１１−４３０４７号公報（請求項１） 特開２００３−５４４１２号公報（請求項１） Conventionally, various types of carts that can be nested have been proposed, such as a cart in which the base plate is repelled and placed in a standby state, or a cart in which the base plate is foldable. In the case of a cart that lifts the base plate and is in a standby state, it cannot be reduced in the length direction. Therefore, when nesting is performed, there is a problem that a standby space is taken up. As a trolley | bogie provided with a foldable baseplate, it is disclosed by Unexamined-Japanese-Patent No. 11-43047 or Unexamined-Japanese-Patent No. 2003-54412, However, the trolley | bogie of the description of Unexamined-Japanese-Patent No. 11-43047 folds a trolley | bogie. When assembling, the front frame does not move smoothly back and forth with respect to the guide frame due to frictional resistance between the front frame and the guide frame. Moreover, although the front frame moves smoothly back and forth with respect to the guide frame, the transportation cart described in Japanese Patent Laid-Open No. 2003-54412 has a complicated structure and a large number of parts, so the failure probability is high and the cost is suppressed. There is a problem that you can not.

運搬用台車１０は、キャスター７、７を付設した第１横部材１ａに固定される第１側面枠体３ａと、第１側面枠体３ａと所定間隔あけて対向して配置されるキャスター７、７を付設した第２横部材１ｂに固定される第２側面枠体３ｂと、第１側面枠体３ａの下方部材３３にＬ字形状の連結部材４３を介して回動自在に軸支される平面視が矩形で所定の厚さを有する台板４と、台板４の下方側にあり、第１側面枠体３ａと第２側面枠体３ｂを連結すると共に、長さ方向に伸縮自在の伸縮連結部材２とを備える。また、運搬用台車１０は、第１側面枠体３ａ、第１側面枠体３ａ及び伸縮連結部材２で形成される待機位置（図２）における形態が略Ｈ字形状であり、ネスティング構造を採る。   The transport cart 10 includes a first side frame 3a fixed to the first lateral member 1a provided with casters 7, 7, and a caster 7, which is arranged to face the first side frame 3a with a predetermined interval, 7 is pivotally supported via a L-shaped connecting member 43 on a second side frame 3b fixed to the second lateral member 1b provided with 7 and a lower member 33 of the first side frame 3a. The base plate 4 is rectangular in plan view and has a predetermined thickness. The base plate 4 is located below the base plate 4 and connects the first side face frame 3a and the second side face frame 3b, and is extendable in the length direction. The telescopic connecting member 2 is provided. Further, the transport carriage 10 is substantially H-shaped in a standby position (FIG. 2) formed by the first side frame body 3a, the first side frame body 3a, and the telescopic connection member 2, and adopts a nesting structure. .

第１側面枠体３ａは、２本の縦部材と６本の横桟部材とから形成され、第１横部材１ａのやや奥側（側寄り）に立設された連結支柱３１ａと接続している。また、第１側面枠体３ａの上方側には待機位置に立掛けられた台板４を留めるフック材３２ａを有している。第２側面枠体３ｂは、フック材３２ａが無いこと以外は第１側面枠体３ａと同じものである。   The first side surface frame 3a is formed of two vertical members and six horizontal beam members, and is connected to a connecting column 31a that is erected on the slightly back side (side) of the first horizontal member 1a. Yes. A hook member 32a is provided on the upper side of the first side face frame 3a to fasten the base plate 4 standing at the standby position. The second side frame 3b is the same as the first side frame 3a except that the hook material 32a is not provided.

第１横部材１ａの下面には２個のキャスター７、７を有し、内側面の両端部分には台板４の四隅の中の２隅が載置される載置面を形成する台座１１ａ、１１ａを有している。第２横部材１ｂも同様に、その下面には２個のキャスター７、７を有し、内側面の両端部分には台板４の四隅の中の他の２隅が載置される載置面を形成する台座１１ｂ、１１ｂを有している。   Two casters 7 and 7 are provided on the lower surface of the first lateral member 1a, and a pedestal 11a that forms a mounting surface on which two of the four corners of the base plate 4 are mounted on both end portions of the inner surface. 11a. Similarly, the second horizontal member 1b has two casters 7 and 7 on its lower surface, and the other two corners of the four corners of the base plate 4 are placed on both end portions of the inner surface. It has the bases 11b and 11b which form a surface.

台板４は１つの短辺側が、第１側面枠体３ａの下方部材３３にＬ字形状の連結部材４３を介して回動自在に軸支されている。台板４の裏面はＬ字形状の連結部材４３が固定される基部側凹部４５と、組み立て位置における伸縮連結部材２と支持部材５を収容する縦凹部４１と、手が入る把持用凹部４４と、フック材３２ａが掛かる留め部を有している。また、台板４の中央側には支持部材５の一端が取り付けられた軸支部４２を有する。組み立て位置にある台板４は、四隅が第１横部材１ａ、第２横部材１ｂ及び４つの台座１１ａに載置される。この台板４を待機位置とするには、台板４を手で持ち上げ、軸支部３３を支点に回動させ第１側面枠体３ａ側に立掛け、フック材３２ａを台板４に留めて固定しておく。後述するように、組み立て位置から待機位置へ台板４を回動移動させる際、台板４の移動に連動して伸縮連結部材２が縮小し、第１側面枠体３ａと第２横部材１ｂ間が縮小する。   One short side of the base plate 4 is pivotally supported on the lower member 33 of the first side frame 3a via an L-shaped connecting member 43. The back surface of the base plate 4 has a base-side concave portion 45 to which an L-shaped connecting member 43 is fixed, a vertical concave portion 41 that accommodates the telescopic connecting member 2 and the support member 5 at the assembly position, and a gripping concave portion 44 into which a hand enters. The hook member 32a has a fastening portion. Further, the center side of the base plate 4 has a shaft support portion 42 to which one end of the support member 5 is attached. The base plate 4 in the assembly position is placed on the first lateral member 1a, the second lateral member 1b, and the four pedestals 11a at the four corners. In order to set the base plate 4 to the standby position, the base plate 4 is lifted by hand, the shaft support portion 33 is turned around the fulcrum, and is stood on the first side frame 3a side, and the hook member 32a is fastened to the base plate 4. Keep it fixed. As will be described later, when the base plate 4 is pivotally moved from the assembly position to the standby position, the telescopic connection member 2 is contracted in conjunction with the movement of the base plate 4, and the first side frame body 3a and the second lateral member 1b. The space shrinks.

伸縮連結部材２は、一端が第２側面枠体３ｂに固定される中空の四角断面形状であって下面部分開口の外フレーム部材２１と、一端が第１側面枠体３ａに固定され、外フレーム部材２１内にスライド自在に嵌め込まれると共に、側面の上下且つ所定間隔離れた一側面で都合４箇所にガイドローラ２４ａ〜２４ｃが付設された中空の四角断面形状であって下面部分開口の内フレーム２２とからなる。伸縮連結部材２は、上記構造を採るため僅かな外力を作用させるだけで伸縮自在である。また、伸縮連結部材２の外フレーム部材２１の上面には、支持部材５の一端が軸支されており、更にその第２側面枠体３ｂ側には、組み立て位置において、台板４の把持用凹部４４に収容するフック材２ｂを設けて組み付け位置における台板４の横方向の移動を規制している。外フレーム部材２１と内フレーム部材２２の嵌合形態としては、上記形態に限定されず、ガイドローラが内フレーム部材２２の下面又は上面に付設され、外フレーム部材２１の側板との接触により摩擦を低減する形態であってもよい。また、外フレーム部材２１と内フレーム部材２２は、フッ素系樹脂等の摩擦低減材を使用し、ガイドローラを省略したものであって、両者の嵌合が強度を維持し且つ摩擦を低減できる形態であってもよい。   The telescopic connecting member 2 has a hollow square cross-sectional shape in which one end is fixed to the second side frame 3b, the outer frame member 21 having a lower surface portion opening, and one end is fixed to the first side frame 3a. The inner frame 22 has a hollow quadrangular cross-sectional shape in which guide rollers 24a to 24c are provided at four convenient locations on one side surface, which is slidably fitted in the member 21, and on one side surface at a predetermined interval. It consists of. The expansion / contraction connection member 2 can be expanded and contracted only by applying a slight external force in order to adopt the above structure. Further, one end of the support member 5 is pivotally supported on the upper surface of the outer frame member 21 of the telescopic connecting member 2, and further on the second side frame 3 b side for gripping the base plate 4 at the assembly position. A hook member 2b accommodated in the recess 44 is provided to restrict lateral movement of the base plate 4 at the assembly position. The fitting form of the outer frame member 21 and the inner frame member 22 is not limited to the above form, and a guide roller is attached to the lower surface or the upper surface of the inner frame member 22, and friction is caused by contact with the side plate of the outer frame member 21. The form to reduce may be sufficient. Further, the outer frame member 21 and the inner frame member 22 use a friction reducing material such as a fluorine-based resin, omit the guide roller, and can maintain the strength of the fitting and reduce the friction. It may be.

支持部材５は、台板４の裏面と伸縮連結部材２の外フレーム部材２１の上面を連結すると共に、台板４の回動移動と伸縮連結部材２の伸縮移動を連動させるものである。支持部材５は、本例ではパイプ状物であり、長さ方向に延出する本体部材５１と、本体部材５１の両端からそれぞれ長さ方向に直交する方向に屈曲する両端部材５２、５２とからなり、両端部材５２、５２は、台板４の裏面の軸支部４２と伸縮連結部材２の外フレーム部材２１の軸支部２５において、長さ方向に直交する方向を中心軸に回動自在に軸支されている。すなわち、支持部材５は、伸縮連結部材２の外フレーム部材２１に対して上下方向に回動自在であり、台板４は支持部材５に対して上下方向に回動自在である。   The support member 5 connects the back surface of the base plate 4 and the upper surface of the outer frame member 21 of the telescopic connection member 2 and interlocks the rotational movement of the base plate 4 and the expansion / contraction movement of the telescopic connection member 2. The support member 5 is a pipe-like object in this example, and includes a main body member 51 extending in the length direction, and both end members 52 and 52 bent from both ends of the main body member 51 in a direction perpendicular to the length direction. The both end members 52 and 52 are pivotable about a center axis in a direction orthogonal to the length direction in the shaft support portion 42 on the back surface of the base plate 4 and the shaft support portion 25 of the outer frame member 21 of the telescopic connecting member 2. It is supported. That is, the support member 5 is rotatable in the vertical direction with respect to the outer frame member 21 of the telescopic connecting member 2, and the base plate 4 is rotatable in the vertical direction with respect to the support member 5.

次に、運搬用台車１０において、組み立て位置から待機位置にする場合及び待機位置から組み立て位置にする場合を図４を参照して説明する。組み立て位置から待機位置にする場合、先ず、ｌ１の位置にある台板４の第２側面枠体３ｂ側を手で持ち上げる。台板４は軸支部３３を支点にして回動する。台板４をｌ２の位置まで持ち上げると、支持部材５の台板４側に取り付けられた軸支部４２はｙ１からｙ２へ持ち上げられる。支持部材５は剛体であり伸縮しないため、伸縮連結部材２の外フレーム部材２１を連れ込む。外フレーム部材２１は内フレーム２２とスライド自在であると共に内フレーム２２は第１側面枠体３ａ側に固定されているため縮小し、運搬用台車１０はｘ１からｘ２へ移動する分縮小する。更に台板４はｌ２からｌ３へ回動されると、支持部材５の台板４側に取り付けられた軸支部４２はｙ２からｙ３へ持ち上げられ、同様に、運搬用台車１０はｘ２からｘ３へ移動する分更に縮小する。そして、待機位置では長さ方向に対して約６０％縮小することになる。なお、外フレーム部材２１と内フレーム２２は最大縮小しても、両者が重複して嵌合する部分があるため、縮小率６０％が限度である。なお、待機位置から組み立て位置にする場合は、組み立て位置から待機位置にする場合の逆に行う以外は同じ動きであるため、その説明を省略する。なお、組み立て位置において、第１横部材１ａ及び第２横部材１ｂの上面から上方へ突出している伸縮連結部材２及び支持部材５は、台板４の裏面に形成される縦凹部４１等に収容されるため台板４の水平載置の際障害とならない。 Next, in the transport carriage 10, the case where the assembly position is changed to the standby position and the case where the standby position is changed to the assembly position will be described with reference to FIG. 4. If you standby position from the assembled position, first, lifted by hand second side frame 3b side of the base plate 4 at the position of l 1. The base plate 4 rotates with the shaft support portion 33 as a fulcrum. When the base plate 4 is lifted to the position of l 2 , the shaft support portion 42 attached to the base plate 4 side of the support member 5 is lifted from y 1 to y 2 . Since the support member 5 is a rigid body and does not expand and contract, the outer frame member 21 of the expansion / contraction connection member 2 is brought in. Outer frame member 21 is an inner frame 22 with a movable inner frame 22 and the slide is reduced because it is fixed to the first side frame body 3a side, dolly 10 min reduced moving from x 1 to x 2 . Further, when the base plate 4 is rotated from l 2 to l 3 , the shaft support portion 42 attached to the base plate 4 side of the support member 5 is lifted from y 2 to y 3 . further reduction amount that moves from x 2 to x 3. At the standby position, the length is reduced by about 60%. Even if the outer frame member 21 and the inner frame 22 are reduced to the maximum, there is a portion in which the outer frame member 21 and the inner frame 22 are overlapped with each other, so the reduction rate is 60%. Note that, when changing from the standby position to the assembly position, the operation is the same except that the reverse operation is performed when the assembly position is changed to the standby position. In the assembly position, the telescopic connection member 2 and the support member 5 projecting upward from the upper surfaces of the first and second lateral members 1a and 1b are accommodated in a vertical recess 41 or the like formed on the back surface of the base plate 4. Therefore, it does not become an obstacle when the base plate 4 is placed horizontally.

運搬用台車１０は、待機位置において長さ方向に６０％縮小されたものであるため、２台の運搬用台車１０、１０を長さ方向において、互いに対向するように配置し、ネスティングすれば、スペースを取らない（図７及び図８参照）。なお、運搬用台車１０において、支持部材５を省略することができるが、この場合、３台の運搬用台車１０のネスティングが可能となり、一層の省スペース化を実現できる。   Since the transport cart 10 is reduced by 60% in the length direction at the standby position, if the two transport carts 10 and 10 are arranged to face each other in the length direction and are nested, Does not take up space (see FIGS. 7 and 8). In addition, although the support member 5 can be omitted in the transport carriage 10, in this case, nesting of the three transport carriages 10 is possible, and further space saving can be realized.

次に、本発明の実施の形態における運搬用台車の変形例を図９〜図１３を参照して説明する。なお、図１０、図１１及び図１３は、本発明の参考例となるものである。図９〜図１３において、図１〜図８と同一構成要素には同一符号を付して、その説明を省略し異なる点について主に説明する。すなわち、図９の運搬用台車１０ａにおいて、図１〜図８の運搬用台車１０と異なる点は、第１側面枠体３ａに連結支柱３１ａを取り付ける位置及び第１横部材１ａに連結支柱３１ａを取り付ける位置を側端方向へ変更し、片持ちフレームとした点にある。なお、第２側面枠体３ｂ側においても同様である。これにより、ネスティングの際、側方向のネスティングが深くなり、突出する部分が少なくなる。 Next, modified examples of the transportation carriage in the embodiment of the present invention will be described with reference to FIGS. 10, FIG. 11 and FIG. 13 are reference examples of the present invention. 9 to 13, the same components as those in FIGS. 1 to 8 are denoted by the same reference numerals, and the description thereof will be omitted and different points will be mainly described. In other words, the transportation carriage 10a of FIG. 9 differs from the transportation carriage 10 of FIGS. 1 to 8 in that the connection support 31a is attached to the first side frame 3a and the connection support 31a is attached to the first lateral member 1a. The mounting position is changed in the direction of the side edge to make a cantilever frame. The same applies to the second side frame 3b side. As a result, the nesting in the lateral direction is deepened during nesting, and the protruding portion is reduced.

図１０の運搬用台車１０ｂにおいて、図１〜図８の運搬用台車１０と異なる点は、支持部材５の設置を省略した点及び更にもう１個のキャスター７を伸縮連結部材２の外フレーム部材２１の下面に形成した点にある。運搬用台車１０ｂによれば、組み立て位置から待機位置にする場合及び待機位置から組み立て位置にする場合、台板４の移動と第２側面枠体３ｂの内側への移動をそれぞれ手等で独立して行う必要があるが、構成部材を省略でき、コストダウンが図れる。   10 differs from the transportation carriage 10 in FIGS. 1 to 8 in that the installation of the support member 5 is omitted and another caster 7 is connected to the outer frame member of the telescopic connection member 2. It is in the point formed in the lower surface of 21. According to the transport carriage 10b, when the assembly position is changed to the standby position and when the standby position is changed to the assembly position, the movement of the base plate 4 and the movement to the inner side of the second side surface frame 3b are made independent by hand. However, the structural members can be omitted, and the cost can be reduced.

図１１の運搬用台車１０ｃにおいて、図１０の運搬用台車１０ｂと異なる点は、更に下面にキャスター７、７を付設した第３横部材１ｃを伸縮連結部材２の外フレーム部材２１の下面に形成した点にある。運搬用台車１０ｃによれば、運搬用台車１０ｂと同様の効果を奏する。   11 is different from the transportation carriage 10b in FIG. 10 in that a third horizontal member 1c having casters 7 and 7 attached to the lower surface is formed on the lower surface of the outer frame member 21 of the telescopic connecting member 2. It is in the point. According to the transport carriage 10c, the same effect as the transport carriage 10b is achieved.

図１２の運搬用台車１０ｄにおいて、図１〜図８の運搬用台車１０と異なる点は、連結支柱３１ａ、３１ｂ、伸縮連結部材２及び支持部材５をそれぞれ更に１個付設した点、すなわちダブルフレームとした点にある。運搬用台車１０ｄによれば、全体の剛性が増す他は、運搬用台車１０と同様の効果を奏する。   12 is different from the transportation carriage 10 in FIGS. 1 to 8 in that one connection post 31a, 31b, the expansion / contraction connection member 2 and the support member 5 are additionally provided, that is, a double frame. It is in the point. According to the transporting carriage 10d, the same effects as the transporting carriage 10 are obtained except that the overall rigidity is increased.

図１３の運搬用台車ｅにおいて、図１２の運搬用台車１０ｄと異なる点は、台板４の形態を変更した点、及び支持部材５を省略した点である。すなわち、運搬用台車１０ｅは、キャスター７を付設した第１横部材１ａに固定される第１側面枠体３ａと、第１側面枠体３ａと所定間隔あけて対向して配置されるキャスター７を付設した第２横部材１ｂに固定される第２側面枠体３ｂと、第１側面枠体３ａ及び第２側面枠体３ｂの下方部に両端がそれぞれ回動自在に付設される中央で折り畳み自在の折り畳み台板４ａと、折り畳み台板４ａの下方側にあり、第１側面枠体３ａと第２側面枠体３ｂを連結すると共に、長さ方向に伸縮自在の伸縮連結部材２とを備える。   13 differs from the transportation carriage 10d in FIG. 12 in that the form of the base plate 4 is changed and the support member 5 is omitted. That is, the transport cart 10e includes a first side frame 3a fixed to the first lateral member 1a provided with the casters 7, and a caster 7 arranged to face the first side frame 3a with a predetermined interval. The second side frame 3b fixed to the attached second lateral member 1b, and the center of the first side frame 3a and the lower side of the second side frame 3b, both ends of which are pivotally attached to each other, can be folded at the center. The folding base plate 4a and the folding base plate 4a are provided below the folding base plate 4a and connect the first side face frame body 3a and the second side face frame body 3b and the telescopic connecting member 2 that is extendable in the length direction.

台板４ａは、２枚の台板用部材を中央で蝶番で接続し、２つ折りで折畳めるようにしたものであり、一端を伸縮連結部材２の内ケースの端側に回動自在に軸支し、他端を伸縮連結部材２の外ケース２１の端側に回動自在に軸支したものである。運搬用台車ｅにおいて、組み立て位置から待機位置にする場合及び待機位置から組み立て位置にする場合、第１側面枠体３ａまたは第２側面枠体３ｂを内側に移動させるだけで長さ方向における長さを縮小することができる。また、運搬用台車１０ｅにおいて、伸縮連結部材２及び支持部材５はそれぞれ１つであってもよい。従来の運搬用台車において、折り畳み式台板を備えたネスティング構造の台車はあるものの、本願発明のような簡易な構造のものはない。   The base plate 4a is formed by connecting two base plate members with a hinge at the center and folding the base plate 4a in two. One end of the base plate 4a is pivotable to the end side of the inner case of the telescopic connecting member 2. The other end is pivotally supported on the end side of the outer case 21 of the telescopic connecting member 2 so as to be rotatable. In the transport cart e, when the assembly position is changed to the standby position and when the standby position is changed to the assembly position, the length in the length direction can be obtained simply by moving the first side frame 3a or the second side frame 3b inward. Can be reduced. Further, in the transport carriage 10e, the number of the expansion / contraction connection member 2 and the support member 5 may be one. In the conventional transporting cart, there is a cart with a nesting structure provided with a folding base plate, but there is no simple cart as in the present invention.
