以下，使用圖1~5對本發明之一實施形態的搬送用台車1進行說明。Hereinafter, a transport trolley 1 according to an embodiment of the present invention will be described using FIGS. 1 to 5.

（搬送用台車的概要） 圖1係本實施形態的框架為打開狀態的搬送用台車1的立體圖。搬送用台車1亦稱為籠車，其係用以在3個框架（左側框架2、右側框架3、背側框架B）的框內的裝載空間裝載貨物並搬送的台車。(Summary of transport trolley) FIG. 1 is a perspective view of the transport trolley 1 with the frame of the present embodiment opened. The transport trolley 1 is also called a cage, and it is a trolley for loading and transporting goods in the loading space in the frame of three frames (the left frame 2, the right frame 3, and the back frame B).

如圖1所示，搬送用台車1具備左側框架（第1框架）2、右側框架（第2框架）3、背側框架B、撐條6及底部構件10。左側框架2及右側框架3互相面對面。背側框架B將左側框架2的緣部21與右側框架3的緣部31連結。此外，本說明書中的「緣部」意指構成框架各邊的柱狀構件。As shown in FIG. 1, the transportation trolley 1 includes a left side frame (first frame) 2, a right side frame (second frame) 3, a back side frame B, a stay 6, and a bottom member 10. The left frame 2 and the right frame 3 face each other. The back frame B connects the edge 21 of the left frame 2 and the edge 31 of the right frame 3. In addition, the "edge" in this specification means the column-shaped member which comprises each side of a frame.

左側框架2發揮作為裝載空間中的側壁之一的功能。左側框架2透過結合部12支撐於背側框架B。The left side frame 2 functions as one of the side walls in the loading space. The left side frame 2 is supported by the back side frame B through the coupling portion 12.

右側框架3發揮作為裝載空間中的側壁之一的功能。右側框架3透過結合部13支撐於背側框架B。The right side frame 3 functions as one of the side walls in the loading space. The right side frame 3 is supported by the back side frame B through the coupling portion 13.

背側框架B發揮作為裝載空間中的背側側壁的功能。從將貨物裝入搬送用台車1之側（以下稱為前方，將從該前方看去具有背面框架B之側稱為後方）看去，背側框架B垂直地固定在構成底部構件10的底板支承件101的後方端部。再者，背側框架B透過結合部12支撐左側框架2，另一方面，透過結合部13支撐右側框架3。The back frame B functions as a back side wall in the loading space. Viewed from the side where the goods are loaded into the transport trolley 1 (hereinafter referred to as the front, the side with the back frame B seen from the front is referred to as the back), the back side frame B is vertically fixed to the bottom plate constituting the bottom member 10 The rear end of the support 101. In addition, the back frame B supports the left frame 2 through the coupling portion 12, and on the other hand, supports the right frame 3 through the coupling portion 13.

底部構件10具備底板支承件101及底板11，該底板支承件101具備4個車輪15。底板支承件101上，背側框架B垂直地固定於其後方端部。底板支承件101上設有底板11。底板（底部構件）11載置搬送對象的貨物。設置底板11係為了容易裝置貨物，並且使搬送用台車1的姿勢穩定。又，底板支承件101構成為越往前方寬度（與背側框架B平行的方向的寬度）越窄。又，底板支承件101的後方未設置框架，而構成為可使另一相同形狀的底板支承件的前部從其後方***。The bottom member 10 includes a floor support 101 and a floor 11. The floor support 101 includes four wheels 15. On the floor support 101, the back side frame B is vertically fixed to its rear end. The bottom plate 11 is provided on the bottom plate support 101. The bottom plate (bottom member) 11 places the goods to be transported. The bottom plate 11 is provided to facilitate loading of goods and to stabilize the posture of the transportation trolley 1. In addition, the floor support 101 is configured to have a narrower width toward the front (width in the direction parallel to the back frame B). In addition, the rear of the floor support 101 is not provided with a frame, and the front portion of another floor support of the same shape can be inserted from the rear.

撐條6係在將貨物裝載於框架的框內後，開始搬送前，用以將互相面對面的左側框架2與右側框架3連結。The stay 6 is used to connect the left side frame 2 and the right side frame 3 facing each other after loading the goods in the frame of the frame and before starting to transport.

搬送用台車1的前方未設置框架。因此，可將貨物從前方側裝入搬送用台車1，而載置於底板11上。No frame is provided in front of the transport trolley 1. Therefore, the goods can be loaded into the transport trolley 1 from the front side and placed on the floor 11.

此外，如圖1或圖6所示，前輪15F配置成從底板支承件101的前端部稍微突出側邊。藉此，可實現套疊，並且可減少前輪15F與後輪15R在車寬方向上的偏差。因此，可實現防止搬送用台車1傾倒。In addition, as shown in FIG. 1 or FIG. 6, the front wheel 15F is arranged to slightly protrude from the front end portion of the floor support 101 to the side. Thereby, telescoping can be realized, and the deviation of the front wheels 15F and the rear wheels 15R in the vehicle width direction can be reduced. Therefore, it is possible to prevent the transportation trolley 1 from falling over.

圖2係本實施形態的框架為折疊狀態的搬送用台車1的立體圖。如圖2所示，搬送用台車1具備重錘部14。FIG. 2 is a perspective view of the transport trolley 1 in which the frame of this embodiment is in a folded state. As shown in FIG. 2, the transport trolley 1 includes a weight portion 14.

重錘部14係配置於底板支承件（底部構件）101上靠向與背側框架B的相反側，而使該搬送用台車1的重心靠近俯視下的底板支承件101的中央附近的重錘。如圖1或圖7所示，若相較於無重錘部14時的重心G1，配置有重錘部14時的重心G2靠近底部構件10的中央附近。The weight portion 14 is disposed on the floor support (bottom member) 101 on the side opposite to the back side frame B, so that the center of gravity of the transport trolley 1 is close to the center of the floor support 101 in the plan view. . As shown in FIG. 1 or FIG. 7, the center of gravity G2 when the weight portion 14 is arranged is closer to the center of the bottom member 10 than the center of gravity G1 when the weight portion 14 is not provided.

據此，原本由於搬送用台車1上未設置前側框架而其重心G1位於背側框架B側，因此搬送用台車1不穩定，但是藉由配置重錘部14，重心G2靠近底部構件10的中央附近，因此搬送用台車1穩定，而有助於防止往背側框架B側傾倒。According to this, since the front frame is not provided on the transportation trolley 1 and the center of gravity G1 is located on the back frame B side, the transportation trolley 1 is unstable, but by disposing the weight portion 14, the center of gravity G2 is close to the center of the bottom member 10 In the vicinity, the transport trolley 1 is stable and helps prevent the back frame B from falling.

重錘部14係由與構成搬送用台車1的框架、撐條、車輪、車輪的安裝件分開而另外安裝的重錘所形成。本實施形態中，如圖6所示，以熔接等將金屬圓棒14a安裝於中空框架狀底板支承件（底部構件）101的內部而構成。又，重錘的形狀只要適當設計即可，例如可為圓棒（圓柱狀）、稜柱形等的柱狀、球狀、半球狀、扁平形狀等的各種形狀。The weight portion 14 is formed of a weight that is separately installed from the frame, the stays, the wheels, and the attachments of the wheels constituting the carriage 1 for transportation. In the present embodiment, as shown in FIG. 6, the metal round bar 14 a is attached to the inside of the hollow frame-shaped floor support (bottom member) 101 by welding or the like. In addition, the shape of the weight may be appropriately designed, and may be various shapes such as a round bar (cylindrical shape), a prism shape, a column shape, a spherical shape, a hemispherical shape, and a flat shape.

圖4係本實施形態的框架為折疊狀態的搬送用台車1的側面圖。如圖4所示，本實施形態中，從底板支承件101的進深中央（以圖4的箭頭P表示）看去，在遠離背側框架B的一側並與背側框架B平行地延伸的緣部配置重錘部14，但並不限定於這種配置或形態。只要係從底板支承件101的進深中央看去在遠離背側框架B的一側，重錘部14亦可設於在與背側框架B交叉方向上延伸的緣部、作為緣部間支柱的構件、車輪的安裝零件等。FIG. 4 is a side view of the transport trolley 1 in which the frame of the present embodiment is folded. As shown in FIG. 4, in this embodiment, viewed from the depth center of the floor support 101 (indicated by the arrow P in FIG. 4 ), it extends on the side away from the back frame B and parallel to the back frame B The weight portion 14 is arranged at the edge, but it is not limited to this arrangement or form. As long as it is seen from the depth center of the floor support 101 on the side away from the back frame B, the weight portion 14 may also be provided on the edge extending in the direction crossing the back frame B as a support between the edges Components, wheel mounting parts, etc.

搬送用台車1，在未裝載貨物而使其移動的情況下，從提升作業效率的觀點來看，期望使多台搬送用台車1套疊而移動。In the case where the transportation trolley 1 is moved without being loaded, from the viewpoint of improving work efficiency, it is desirable to move a plurality of transportation trolleys 1 in a stack.

因此，左側框架2、右側框架3及底板11可往背側框架B側折疊。詳細而言，首先，將各搬送用台車1的底板11往背側框架B側抬起。亦即，由於底板支承件101與底板11係藉由後部的軸而旋動自如地連結，因此使底板11以該軸為中心旋轉，而靠立於背側框架B側。接著，將各搬送用台車1的框架閉合。亦即，以結合部13近前的軸為中心而將右側框架3往背側框架B側折疊。接著，以結合部12近前的軸為中心而將左側框架2往背側框架B側折疊。藉此，如圖2所示，將底板11、右側框架3及左側框架2相對於背側框架B折疊。再者，撐條6收納於盒體7中。此外，上述底板11將圖中未表示的限制器與框架卡定而保持豎立姿勢。Therefore, the left frame 2, the right frame 3, and the bottom plate 11 can be folded toward the back frame B side. Specifically, first, the bottom plate 11 of each transport trolley 1 is lifted toward the back frame B side. That is, since the bottom plate support 101 and the bottom plate 11 are rotatably connected by the rear axis, the bottom plate 11 is rotated about the axis to lean against the back frame B side. Next, the frame of each transport trolley 1 is closed. That is, the right side frame 3 is folded toward the back side frame B around the axis in front of the coupling portion 13. Next, the left side frame 2 is folded toward the back side frame B around the axis in front of the coupling portion 12. Thereby, as shown in FIG. 2, the bottom plate 11, the right side frame 3 and the left side frame 2 are folded with respect to the back side frame B. Furthermore, the stay 6 is accommodated in the case 7. In addition, the above-mentioned bottom plate 11 locks the restrictor not shown in the figure to the frame and maintains an upright posture.

又，如圖2所示，底板支承件101形成為後部開放的類似平面八字形，如上所述，可從後方***相同形狀的另一搬送用台車的底板支承件。亦即，本實施形態中，底板支承件101的寬度係前方比後方逐漸變窄，因此另一搬送用台車的底板支承件前部小於底板支承件101的後部。因此，藉由將該前部***該後部，可重疊成嵌套狀。據此，可藉由底板支承件的相互嵌合而進行搬送用台車1的套疊。Further, as shown in FIG. 2, the floor support 101 is formed into a flat octagonal shape with an open rear portion. As described above, the floor support of another transport trolley of the same shape can be inserted from the rear. That is, in the present embodiment, the width of the floor support 101 is gradually narrower in the front than in the rear, so the front portion of the floor support of the other transport trolley is smaller than the rear portion of the floor support 101. Therefore, by inserting the front portion into the rear portion, they can be overlapped in a nested shape. According to this, the nesting of the transport trolley 1 can be performed by fitting the floor supports together.

（套疊狀態的搬送用台車） 圖3係表示本實施形態的套疊狀態的多台搬送用台車1的立體圖。如圖3所示，與底板支承件101a相同形狀且左側框架2b、右側框架3b及底板11b為折疊狀態（亦即，圖2所示狀態）的另一搬送用台車1b的底板支承件101b可重疊成嵌套狀而***搬送用台車1a的底板支承件（底部構件）101a。藉此，將多台搬送用台車1依序串接而疊合，因此可一次性使其移動。(Trolley for transport in nested state) FIG. 3 is a perspective view showing a plurality of transport trolleys 1 in a nested state according to this embodiment. As shown in FIG. 3, the floor support 101b of another transport trolley 1b of the same shape as the floor support 101a and the left frame 2b, the right frame 3b, and the floor 11b in a folded state (that is, the state shown in FIG. 2) may be The bottom plate support (bottom member) 101a of the conveyance trolley 1a is inserted in a nested shape. By this, a plurality of transporting trolleys 1 are serially connected and stacked, so that they can be moved at once.

圖3中雖表示5台搬送用台車1套疊的狀態，但亦可將台數多於5台的搬送用台車1套疊。使更多搬送用台車1為套疊狀態而移動，從提升作業效率並且節省人力的觀點來看為較佳。又，在不使用時，使更多搬送用台車1為套疊狀態而保管，從省空間的觀點來看為較佳。此外，雖然以使底板支承件101形成平面八字形而進行說明，但並不限定於八字形，只要為半圓形等可套疊的形狀即可。Although FIG. 3 shows a state in which five transport trolleys are stacked one by one, it is also possible to stack one transport trolley with more than five units. It is preferable to move more transport trolleys 1 in the telescopic state from the viewpoint of improving work efficiency and saving manpower. In addition, when not in use, it is preferable to store more transport trolleys 1 in a nested state from the viewpoint of space saving. In addition, although the description is made by forming the bottom plate support 101 into a flat figure eight shape, it is not limited to a figure eight shape as long as it can be nested in a semicircular shape or the like.

圖5係本實施形態的框架折疊並整體傾斜狀態的搬送用台車1的側視圖。藉由安裝有重錘部14，在使背側框架B以底板支承件101側的緣部B1為軸而往與左側框架2及右側框架3相反側傾斜時，搬送用台車1會順勢倒向抵消傾斜的方向。藉此，可防止搬送用台車1傾倒。FIG. 5 is a side view of the transport trolley 1 in a state where the frame of the present embodiment is folded and tilted as a whole. By attaching the weight portion 14, when the back frame B is tilted toward the side opposite to the left frame 2 and the right frame 3 with the edge portion B1 on the floor support 101 side as the axis, the transport trolley 1 will be reversed. Counteract the direction of tilt. This can prevent the transport trolley 1 from falling over.

如圖5所示，搬送用台車1的傾斜角θ係鉛垂線與左側框架2的長度方向所構成的角度。搬送用台車1具備重錘部14，因此相較於不具備重錘部14的形態，即便使搬送用台車1以更大的傾斜角θ傾斜，亦可恢復原本的姿勢，因此可防止傾倒。As shown in FIG. 5, the inclination angle θ of the transportation trolley 1 is an angle formed by a vertical line and the longitudinal direction of the left frame 2. Since the transportation trolley 1 includes the weight portion 14, it is possible to restore the original posture even if the transportation trolley 1 is tilted at a larger inclination angle θ compared to the configuration without the weight portion 14, so that it can prevent falling.

此外，上述雖說明將柱狀的重錘安裝於底板支承件（底部構件）101的下部而構成重錘部14，但重錘的形狀及設置形態並不限定於此。例如，亦可為圖6所示的另一實施形態。圖6係表示另一實施形態的底板支承件101的例子的俯視圖。如圖6所示，以熔接等將重錘的金屬圓棒（金屬棒）14a安裝於中空框架狀底板支承件（底部構件）101的內部。亦即，重錘亦可為容納於底部構件10的框架狀底板支承件101內的金屬製圓棒（金屬棒）。藉此，由於重錘容納於底板支承件101內，因此不用變更外觀而可使搬送用台車1穩定。In addition, although it has been described above that the columnar weight is attached to the lower portion of the floor support (bottom member) 101 to constitute the weight portion 14, the shape and installation form of the weight are not limited to this. For example, it may be another embodiment shown in FIG. 6. FIG. 6 is a plan view showing an example of a floor support 101 according to another embodiment. As shown in FIG. 6, the metal round bar (metal bar) 14 a of the weight is attached to the inside of the hollow frame-shaped bottom plate support (bottom member) 101 by welding or the like. That is, the weight may be a metal round bar (metal rod) accommodated in the frame-shaped floor support 101 of the bottom member 10. Thereby, since the weight is accommodated in the floor support 101, the conveyance trolley 1 can be stabilized without changing the appearance.

（實施例） 以下說明關於藉由重錘部14來防止搬送用台車1往背面側傾倒的效果的實施例。作為實施例1，於框架為折疊狀態的搬送用台車1上設置重錘部14並使其傾斜。其結果，傾斜角θ在13.4度以內不會傾倒至背面側而可恢復原本狀態（圖4的狀態）。除了安裝重錘部14以外，使用相同形狀的現有製品的比較例1中，傾斜角θ在9.9度以內可恢復原本狀態，但再傾斜就會傾倒。由該結果顯示了藉由安裝重錘部14具有防止傾倒的改善效果。此外，上述傾斜角θ係由3次實驗所得測量值的平均值。(Example) The following describes an example of the effect of preventing the transport trolley 1 from tipping toward the back side by the weight portion 14. As the first embodiment, a weight portion 14 is provided on a transport trolley 1 with a frame in a folded state and tilted. As a result, the tilt angle θ can be restored to the original state (the state of FIG. 4) without being tilted to the back side within 13.4 degrees. In addition to installing the weight portion 14, in Comparative Example 1 using a conventional product of the same shape, the inclination angle θ can be restored to the original state within 9.9 degrees, but if it is tilted again, it will fall over. From this result, it is shown that the installation of the weight part 14 has an improved effect of preventing falling. In addition, the above-mentioned inclination angle θ is an average value of measured values obtained from three experiments.

作為實施例2，於框架為打開狀態（可裝載貨物的狀態）的搬送用台車1上安裝重錘部14並使其傾斜。其結果，傾斜角θ在41.9度以內不會傾倒至背面側而可恢復原本狀態。除了使用與比較例1相同的現有製品以外，進行與實施例2相同操作的比較例2中，傾斜角θ在17.2度以內可恢復原本狀態，但再傾斜就會傾倒。由該結果顯示了藉由安裝重錘部14具有防止傾倒的改善效果。此外，上述傾斜角θ係由3次實驗所得測量值的平均值。As Example 2, the weight part 14 is attached to the conveyance trolley 1 whose frame is in an open state (a state where goods can be loaded) and tilted. As a result, the inclination angle θ can be restored to the original state without being tilted to the back side within 41.9 degrees. In Comparative Example 2 which performs the same operation as in Example 2 except that the same conventional product as Comparative Example 1 is used, the tilt angle θ can be restored to its original state within 17.2 degrees, but tilting will cause it to fall. From this result, it is shown that the installation of the weight part 14 has an improved effect of preventing falling. In addition, the above-mentioned inclination angle θ is an average value of measured values obtained from three experiments.

本發明並不限定於上述各實施形態，在申請專利範圍所示範圍內可進行各種變更，將不同實施形態分別揭示的技術手段適當組合而得的實施形態亦包含於本發明之技術的範圍。The present invention is not limited to the above-mentioned embodiments, and various changes can be made within the scope shown in the patent application scope. Embodiments obtained by appropriately combining the technical means disclosed in different embodiments are also included in the technical scope of the present invention.
