(Composition of transportation cart)
The configuration of the transportation carriage according to this embodiment will be described with reference to FIGS. FIG. 1 is a perspective view showing a transport cart according to the present embodiment in an unfolded state. FIG. 2 is a perspective view showing the transport carriage according to the present embodiment, in which only the front panel is in a folded state. FIG. 3 is a perspective view in which the transport carriage according to the present embodiment is in a folded state. FIG. 4 is a perspective view of the cart body. FIG. 5 is a partially enlarged front view of the cart body. FIG. 6 is a view of the front panel as seen from the back side. It should be noted that the transportation cart is "deployed" means that each panel of the transportation cart is spread, each panel is assembled in a box shape, and a heat insulating space is formed between the plurality of panels. State. In addition, the transportation cart is “folded” means that each panel of the transportation cart is folded and a heat insulating space is not formed in the plurality of panels.

  As shown in FIGS. 1 to 3, the transporting carriage 10 according to the present embodiment includes a carriage main body 50 and a plurality of (in this case, six) provided in such a manner that the carriage main body 50 can be expanded and folded. Panels 11 to 16 are provided. Among these, a plurality of panels 11 to 16 are unfolded and assembled into a box shape (see FIG. 1), and a folded state in which the plurality of panels 11 to 16 can be nested with other transport carts by folding. (See FIG. 3).

  The transport cart 10 is used when storing or transporting a load that needs to be kept cold or warm in, for example, a store, a factory, a distribution process, or the like. In such a transport cart 10, the storage space 20 that can store a load is surrounded by the six panels 11 to 16, whereby the temperature change inside the transport cart 10 is suppressed as much as possible. It is configured as follows. On the other hand, when the transport cart 10 is not used, by nesting with another identical transport cart 10 (part of the transport cart 10 is overlapped with another transport cart 10 adjacent in the lateral direction). A plurality of transport carts 10 can be stored compactly.

  Next, the configuration of the cart body 50 will be described with reference to FIG. As shown in FIG. 4, the cart body 50 includes a first side frame 51, a second side frame 52, and a connecting member 53 that connects the first side frame 51 and the second side frame 52 to each other. Yes. In this case, the carriage main body 50 includes six wheels 61 to 66, and the wheels 61 to 66 are attached downward from the connecting member 53.

  The 1st side frame 51 is provided in the longitudinal direction one end part (X direction minus side edge part) of the trolley | bogie main body 50, and protrudes upwards from the connection member 53 (Z direction plus side). The first side frame 51 is formed in a ladder shape, and includes a pair of vertical rods 55 and a plurality of horizontal rails 56 that respectively extend in the horizontal direction (Y direction) between the pair of vertical rods 55. . The plurality of horizontal rails 56 are arranged at equal intervals along the vertical direction (Z direction). Two wheels 61 and 62 are provided below the first side frame 51. One (Y direction plus side) vertical rod 55 of the pair of vertical rods 55 is directly connected to a wheel mounting frame 69 (described later). On the other hand, the other vertical rod 55 (Y direction minus side) is not directly connected to the wheel mounting frame 69 but is separated from the wheel mounting frame 69. This prevents the central frame 57 of the other transport carriage 10 from interfering with the vertical gutter 55 during nesting. In addition, the lowermost horizontal rail 56 is connected to the wheel mounting frame 69 by a central connecting rod 54. However, the present invention is not limited to this, and both the pair of vertical rods 55 may not be directly coupled to the wheel mounting frame 69 but may be coupled to the wheel mounting frame 69 only by the central coupling rod 54.

  The second side frame 52 is provided at the other end portion in the longitudinal direction (X direction plus side end portion) of the carriage main body 50, and protrudes upward from the connecting member 53 (Z direction plus side). The configuration of the second side frame 52 is substantially the same as the configuration of the first side frame 51 described above, and is arranged so as to be point-symmetric with the first side frame 51 in plan view. Two wheels 65 and 66 are provided below the second side frame 52.

  The connecting member 53 has a substantially king shape (a shape in which two “E” characters are back-to-back) in a plan view, and is attached to the central frame 57 extending in the longitudinal direction (X direction) of the carriage body 50 and the central frame 57, respectively. It has three wheel mounting frames 67-69 connected.

  The center frame 57 is located at a substantially central portion in the width direction (Y direction) of the carriage main body 50. The central frame 57 has sufficient strength to hold the load of the transporting carriage 10 and its load, but has a narrow width that does not interfere with nesting of the transporting carriages 10. . The center frame 57 is provided at a position higher than the wheel mounting frames 67 to 69 so as not to interfere with the wheel mounting frames 67 to 69 of the other transport carriages 10 during nesting.

  The three wheel mounting frames 67 to 69 each extend in a direction (Y direction) orthogonal to the central frame 57. The wheel mounting frames 67 to 69 include a first wheel mounting frame 67 positioned on the first side frame 51 side, and a second wheel mounting frame 68 positioned between the first side frame 51 and the second side frame 52. And a third wheel mounting frame 69 located on the second side frame 52 side.

  The first wheel mounting frame 67 and the second wheel mounting frame 68 are arranged at an interval in the longitudinal direction (X direction) of the carriage main body 50. Further, the second wheel mounting frame 68 and the third wheel mounting frame 69 are arranged with a gap in the longitudinal direction (X direction) of the carriage main body 50. In this case, the distance between the first wheel mounting frame 67 and the second wheel mounting frame 68 may be equal to or different from the distance between the second wheel mounting frame 68 and the third wheel mounting frame 69.

  The first wheel mounting frame 67 is provided at one end in the longitudinal direction of the center frame 57 (X direction minus side end). A first wheel 61 and a second wheel 62 are attached to both ends in the longitudinal direction of the first wheel mounting frame 67 (both ends in the Y direction), respectively.

  The second wheel mounting frame 68 is provided at the center in the longitudinal direction (X direction center) of the center frame 57. A third wheel 63 and a fourth wheel 64 are attached to both ends in the longitudinal direction of the second wheel mounting frame 68 (both ends in the Y direction), respectively. The width (the length in the X direction) of the second wheel mounting frame 68 is so thin that it does not interfere with nesting of the transport carriages 10.

  The third wheel mounting frame 69 is provided at the other end in the longitudinal direction of the center frame 57 (X direction plus side end). A fifth wheel 65 and a sixth wheel 66 are attached to both ends in the longitudinal direction of the third wheel mounting frame 69 (both ends in the Y direction), respectively.

  As described above, the wheels 61 to 66 include the first wheel 61, the second wheel 62, the third wheel 63, the fourth wheel 64, the fifth wheel 65, and the sixth wheel 66. Among these, the 1st wheel 61, the 2nd wheel 62, the 5th wheel 65, and the 6th wheel 66 are freewheels, and while turning along a horizontal axle, respectively, the turn extended in the perpendicular direction (Z direction) It can be swiveled by a shaft. On the other hand, the third wheel 63 and the fourth wheel 64 are fixed wheels, and each rotate along a horizontal axle, but cannot turn around a vertical direction (Z direction) axis.

  It should be noted that the wheels 61 to 66 are arranged in front of and behind the central fixed wheel (the third wheel 63 and the fourth wheel 64) so that when traveling with a load on the transportation carriage 10, the vehicle can stably travel straight. Any one of the free wheels (the first wheel 61 and the second wheel 62, or the fifth wheel 65 and the sixth wheel 66) may be combined and grounded. In addition, when a load is not placed on the carriage 10, the center fixed wheels (the third wheel 63 and the fourth wheel 64) are grounded to facilitate turning and nesting and to make a small turn easier. Instead, only the front and rear universal wheels (the first wheel 61, the second wheel 62, the fifth wheel 65, and the sixth wheel 66) may be grounded. The cart body 50 is not limited to this, and has four wheels 61, 62, 65, 66, and does not have the second wheel mounting frame 68, the third wheel 63, and the fourth wheel 64. Also good.

  Further, a foldable bottom plate 58 is provided on the connecting member 53. The bottom plate 58 has a substantially rectangular parallelepiped shape, extends between the first side frame 51 and the second side frame 52 in the longitudinal direction (X direction), and the first side frame 51 and the first side frame in the short direction (Y direction). The two side frames 52 have substantially the same length. Further, the bottom plate 58 has sufficient strength to hold the load of the load on the transport carriage 10.

  The bottom plate 58 is movable with respect to the connecting member 53, and is in an unfolded state (see FIGS. 1, 2 and 4) arranged on the connecting member 53, and lifted with respect to the connecting member 53 to the second side. A folded state (see FIG. 3) folded around the frame 52 can be taken. That is, when the panels 11 to 16 are expanded and assembled in a box shape (see FIGS. 1, 2, and 4), the bottom plate 58 is disposed in a horizontal expanded state. On the other hand, when the plurality of panels 11 to 16 are folded to assume a folded state (see FIG. 3), the bottom plate 58 is lifted vertically and disposed in the folded state.

  As shown in FIG. 5, the bottom plate 58 is rotatable about a fulcrum 58 a provided on the inner side (X direction minus side) of the central connecting rod 54 and the vertical rod 55. This fulcrum part 58a is located below (Z direction minus side) below the bottom panel 16 (described later). In this case, the whole connection part (fulcrum part 58a) which connects the baseplate 58 and the center connection rod 54 or the vertical rod 55 is located outside the panels 11-16. Thereby, when the circumference | surroundings are enclosed by the heat insulating material so that it may mention later, a connection part does not straddle over the accommodation space 20 (after-mentioned) and external air, and a connection part becomes a heat bridge. Thus, it is possible to prevent the heat insulation of the accommodation space 20 from being deteriorated. Further, there is no possibility that the connecting portion (fulcrum portion 58a) interferes with the panels 11 to 16 while the bottom plate 58 is moved between the folded state and the unfolded state.

(Panel structure)
Next, the configuration of the panels 11 to 16 will be described with reference to FIGS. 1 to 3.

  The panels 11 to 16 are provided so as to be expandable and foldable with respect to the carriage main body 50 as a whole. As described above, the panels 11 to 16 can be nested with the expanded state (FIG. 1) assembled in a box shape. The folded state (FIG. 3) can be taken. Moreover, FIG. 2 has shown the case where only the front panel 12 is in the folding state among the panels 11-16.

  As shown in FIG. 1, the panels 11 to 16 have a substantially rectangular parallelepiped shape in the unfolded state, and include a top panel 11, a front panel 12, a back panel 13, a first side panel 14, and a second panel. A side panel 15 and a bottom panel 16 are included. The top panel 11, the front panel 12, the back panel 13, the first side panel 14, the second side panel 15, and the bottom panel 16 are the main surfaces (among the six surfaces constituting each panel). The widest pair of surfaces facing the opposite sides) has a substantially rectangular shape. Further, the main surface of the front panel 12 and the back panel 13 have substantially the same size, and the first side panel 14 and the second side panel 15 have substantially the same main surface. It has a size. Each panel 11-16 consists of a plate-shaped member with rigidity, respectively, and is not deform | transforming flexibly at the time of use.

  By being surrounded by the six panels 11 to 16 in the unfolded state, it is possible to form the accommodation space 20 for accommodating the load. When these panels 11 to 16 are in the unfolded state, a substantially rectangular parallelepiped housing space 20 is formed between the panels 11 to 16. As will be described later, when the surroundings of the housing space 20 are surrounded by a heat insulating material, inflow and outflow of heat from the outside are limited, and heat insulation can be maintained. Further, at least a part of the six panels 11 to 16 is provided so as to be movable with respect to the other adjacent panels 11 to 16. As a result, the transport carriage 10 can be changed from the expanded state in which the accommodation space 20 is formed to the folded state in which the accommodation space 20 is not formed, and can be changed from the folded state to the expanded state. For this reason, when the transporting carriage 10 is not used, the panels 11 to 16 can be folded to be nested with other transporting carriages 10. In the unfolded state, the six panels 11 to 16 each have a peripheral edge that is in close contact with any of the other panels 11 to 16, thereby ensuring sealing of the accommodation space 20.

  Each of the six panels 11 to 16 includes a heat insulating panel having a heat insulating portion 40 including a vacuum heat insulating material 41 as described later (see FIG. 7). In addition, in this Embodiment, although the six panels 11-16 contain the vacuum heat insulating material 41, respectively, it is not limited to this. Some or all of the panels 11 to 16 may include a heat insulating material such as a foam heat insulating material.

  Next, the configuration of each of the panels 11 to 16 will be further described. In the following, “panels 11 to 16 (partial panels) are parallel (perpendicular) to a predetermined surface” means that “the main surfaces of panels 11 to 16 (partial panels) are to a predetermined surface. "Parallel (vertical)".

(Top panel)

Further, in the unfolded state, the top panel 11 is disposed above the first side frame 51 and the second side frame 52, the first side panel 14, and the front panel 12 of the carriage body 50. The top panel 11 is disposed on the front side (Y direction minus side) of the back panel 13 and is disposed on the first side surface side (X direction minus side) of the second side panel 15.

  The top panel 11 has a structure that can be partially opened and closed. The top panel 11 is positioned on the first side frame 51 side and the second side frame 52 side. And a second top surface partial panel 11b larger than the partial panel 11a. Among these, the 1st top surface partial panel 11a is attached to the 1st side panel 14 so that folding is possible via the 1st top surface hinge member 21c (refer FIG. 10 (a)-(c)). Further, the second top surface partial panel 11b is foldably attached to the first top surface partial panel 11a via a second top surface hinge member 21d (see FIGS. 10A to 10C). .

  The first top surface partial panel 11a and the second top surface partial panel 11b are both horizontally (parallel to the XY plane) in the unfolded state (FIG. 1). On the other hand, in the folded state (FIG. 3), the first top surface partial panel 11a is disposed horizontally, while the second top surface partial panel 11b is folded downward and is separated from the first top surface partial panel 11a. It is arranged to hang down. At this time, the second top surface partial panel 11b is disposed around the inner side of the first side frame 51 and is parallel to the YZ plane.

In the deployed state, the front panel 12 is disposed between the first side panel 14 and the second side panel 15.

  The front panel 12 has a foldable structure, and is located on the first front partial panel 12a located on the first side frame 51 side, the second front partial panel 12b located on the middle, and the second side frame 52 side. And a third front partial panel 12c. Of these, the first front partial panel 12a is foldably attached to the first side panel 14 via a first front hinge member 22a (see FIGS. 9A to 9C). The second front partial panel 12b is foldably attached to the first front partial panel 12a via a second front hinge member 22b (see FIGS. 9A to 9C). Further, the third front partial panel 12c is foldably attached to the second front partial panel 12b via a third front hinge member 22c (see FIGS. 9A to 9C).

  The first front partial panel 12a, the second front partial panel 12b, and the third front partial panel 12c are all arranged perpendicular to the horizontal plane (XY plane) (parallel to the ZX plane) in the unfolded state (FIG. 1). The On the other hand, in the folded state (FIG. 3), the first front partial panel 12a is located on the front side (Y direction minus side) of the first side panel 14. Further, the second front partial panel 12b and the third front partial panel 12c are folded so as to overlap each other, and further rotate around the vertical axis (Z-direction axis) to be outside the first side panel 14 (minus in the X direction). Side). At this time, the second front partial panel 12b and the third front partial panel 12c are folded and disposed around the outside of the first side frame 51 and are parallel to the YZ plane.

  Thus, the accommodation space 20 for accommodating a load is provided by disposing the second front partial panel 12b and the third front partial panel 12c outside the first side frame 51 (X direction minus side) in the folded state. Can be secured widely. Further, when the bottom plate 58 is lifted to the second side frame 52 side, the first front partial panel 12a, the second front partial panel 12b, and the third front partial panel 12c are prevented from interfering with the moving bottom plate 58. Yes. The width (length in the X direction) of the first front partial panel 12a is shorter than the width (length in the X direction) of the second front partial panel 12b and the third front partial panel 12c. The width (length in the X direction) of 12b is substantially the same as the width (length in the X direction) of the third front partial panel 12c. The widths of the second front partial panel 12b and the third front partial panel 12c are substantially the same as the width of the first side frame 51 (the length in the Y direction) or longer than the width of the first side frame 51.

That is, the detachable members 34a to 34d are respectively provided between the detachable members 34a and 34b adjacent to each other, between the detachable members 34b and 34c, between the detachable members 34c and 34d, and between the detachable members 33d and 35 (described later). The visual confirmation part 28 where the boundary line between the front panel 12 and the bottom panel 16 is exposed is not provided. For this reason, in each visual confirmation part 28, by confirming the boundary line of the front panel 12 and the bottom panel 16 visually, it can be confirmed easily whether the front panel 12 and the bottom panel 16 are correctly adhere | attached. it can. Thereby, it is possible to prevent the airtightness (heat insulating property) of the accommodation space 20 from deteriorating from the gap between the front panel 12 and the bottom panel 16.

  Further, the third front partial panel 12 c of the front panel 12 is detachably connected to the adjacent second side panel 15 by the detachable member 35. The detachable member 35 is composed of a single belt-like member that is elongated in the vertical direction (Z direction). In this case, the detachable member 35 extends over the entire vertical direction (Z direction) from the upper end to the lower end of the third front partial panel 12c.

The other surface fasteners 39b are attached to predetermined positions on the end surfaces (surfaces perpendicular to the main surfaces of the panels) of the top panel 11, the second side panel 15, and the bottom panel 16, respectively.

  In this case, the front panel 12 is attached to the top panel 11, the second side panel 15 or the bottom panel 16 by the hook-and-loop fasteners 39a and 39b, or the front panel 12 is attached to the top panel 11, the second side panel 15 or the bottom panel 16. Can be easily removed. Further, since the hook-and-loop fasteners 39a and 39b have a certain area, they absorb a positional deviation and a dimensional error when the front panel 12 is aligned with the top panel 11, the second side panel 15, or the bottom panel 16. It is easy to finely adjust the mounting position of the front panel 12.

  The configuration of the detachable members 31a to 31d and 32 (see FIGS. 1 and 2) attached to the top panel 11 is substantially the same as the detachable members 33a to 33d, 34a to 34d, and 35. .

  FIG. 3 shows a case where the panels 11 to 16 are in a folded state as described above. As shown in FIG. 3, at least a part of each of the panels 11 to 16 is folded around the first side frame 51 or the second side frame 52 in the folded state.

  That is, around the first side frame 51, the second front partial panel 12b, the third front partial panel 12c, the first side panel 14, the bottom panel 16, in order from the outside (X direction minus side), The second top surface partial panel 11b overlaps. The first side frame 51 is located between the first side panel 14 and the bottom panel 16. In addition, the second side panel 15 and the bottom plate 58 overlap in this order from the outside (X direction plus side) around the second side frame 52. The second side frame 52 is located between the second side panel 15 and the bottom plate 58.

  In this case, a first panel group G1 and a second panel group G2 are formed around the first side frame 51 and the second side frame 52, respectively. Among these, the first panel group G1 includes the second front partial panel 12b, the third front partial panel 12c, the first side panel 14, the first side frame 51, the bottom panel 16, and the second top panel. 11b. The second panel group G <b> 2 includes the second side panel 15, the second side frame 52, and the bottom plate 58. In the present embodiment, the first panel group G1 (second panel group G2) includes not only all or part of the panels 11 to 16, but also the first side frame 51 (second side frame 52), A bottom plate 58 is also included.

  It is preferable that the thickness of each panel 11-16 shall be 5 mm or more and 50 mm or less, respectively. In the present embodiment, the case where the thicknesses of the panels 11 to 16 are the same will be described as an example, but the thicknesses of the panels 11 to 16 may be different from each other. Moreover, the thickness (length in the X direction) of the first side frame 51 and the second side frame 52 is, for example, not less than 10 mm and not more than 50 mm.

  In this Embodiment, the panel container 30 is comprised by the panels 11-16 and the attachment / detachment members 31-37 which connect each panel 11-16 detachably. The panel container 30 can be assembled and disassembled, and can be in an expanded state (see FIG. 1) and a folded state (see FIG. 3). In this case, the panel container 30 is integrated with the carriage main body 50 to form the transportation carriage 10, but not limited thereto, only the panel container 30 may be used independently.

(Internal structure of panel)
Next, the structure of each panel 11-16 is demonstrated. FIG. 7 is a cross-sectional view showing the heat insulating portion 40 of each panel 11-16. FIGS. 8A and 8B are cross-sectional views showing the vacuum heat insulating material 41 included in the heat insulating portion 40.

  As shown in FIG. 7, the heat insulation part 40 of each panel 11-16 is the vacuum heat insulating material 41, the foam heat insulating material 42, the heat insulation outer peripheral part 43, the heat insulating material protection member 44, and the heat shield sheet 45. Have.

  Among these, the vacuum heat insulating material 41 is attached to the foam heat insulating material 42. The vacuum heat insulating material 41 includes a core material 41a and an exterior material 41b provided around the core material 41a. A foam heat insulating material 42 is disposed on the side of the housing space 20 of the vacuum heat insulating material 41 (the lower side in FIG. 7). Thereby, when the load put in the accommodation space 20 collides, the danger that the vacuum heat insulating material 41 will be damaged can be reduced.

  The foam heat insulating material 42 can be disposed adjacent to at least the housing space 20 side of the vacuum heat insulating material 41. As the foam heat insulating material 42, a known foam heat insulating material can be used, and for example, one or both of a polyurethane foam and a polystyrene foam may be used.

  The heat insulating enclosure 43 is formed so as to surround the vacuum heat insulating material 41. The heat insulating enclosure 43 is disposed on the foam heat insulating material 42 and is fixed to the foam heat insulating material 42. By disposing the heat insulating enclosure 43 so as to surround the vacuum heat insulating material 41, the heat insulating performance is improved as compared with the case where the heat insulating enclosure 43 is not arranged. Further, a panel configuration in which the vacuum heat insulating material 41 has substantially the same area as the foam heat insulating material 42 and does not use the heat insulating enclosure 43 is also possible. In this case, although the heat insulation performance can be further improved, there is a fear that the vacuum insulation material 41 breaks due to the intrusion of sharp objects from the side because there is no heat insulation enclosure 43. Note that a slight gap is formed between the heat insulating enclosure 43 and the vacuum heat insulating material 41. Even when the size of the vacuum heat insulating material 41 is slightly changed, the vacuum heat insulating material 41 is not insulated. The enclosure 43 can be accommodated.

  Further, the heat insulating material protecting member 44 is provided on the heat insulating surrounding portion 43 and mainly serves to protect the vacuum heat insulating material 41. As the heat insulating material protecting member 44, for example, a protective material made of an organic polymer can be used.

  The heat shield sheet 45 is disposed so as to wrap around the entire outer periphery of the vacuum heat insulating material 41, the foam heat insulating material 42, the heat insulating enclosure 43, and the heat insulating material protecting member 44. The heat shield sheet 45 can be disposed so as to cover the entire vacuum heat insulating material 41 and the foam heat insulating material 42. Examples of the heat shield sheet 45 include a multilayer sheet including a metal foil, a vapor deposition sheet in which a vapor deposition layer is formed on one side of a resin sheet, and the like.

  Next, the vacuum heat insulating material 41 will be further described. As shown in FIG. 8A, the vacuum heat insulating material 41 is composed of a core material 41a and an exterior material 41b having gas barrier properties, and is a heat insulation material obtained by reducing the pressure inside the exterior material 41b. FIG. 8B is another example of the vacuum heat insulating material 41. In FIG. 8A, a gap is formed at both ends inside the vacuum heat insulating material 41, but in FIG. 8B, no gap is formed. The air gap may or may not be formed depending on the manufacturing method of the vacuum heat insulating material 41.

  As the core material 41a, a material used for a core material of a conventionally known vacuum heat insulating material can be used. For example, powder such as silica, foamed material such as urethane polymer, fiber body such as glass wool, etc. The porous body may be used.

  The exterior material 41b is a member that covers the outer periphery of the core material 41a, and a flexible sheet in which a heat welding layer and a gas barrier layer are sequentially laminated from the core material may be used. As the gas barrier layer, a metal foil, a vapor deposition sheet having a vapor deposition layer formed on one surface of a resin sheet, or the like may be used. For example, aluminum can be used as the metal foil. For the vapor deposition layer, for example, aluminum, aluminum oxide, or silicon oxide can be used.

(Disassembly and assembly of transportation cart)
Next, the operation when disassembling and assembling the transport carriage 10 will be described. 9 to 11 are diagrams for explaining a part of the steps for sequentially disassembling the transport carriage 10.

(Disassembly of transportation cart)
First, as shown in FIG. 1, the case where the six panels 11-16 of the trolley | bogie 10 are expand | deployed and assembled in the box shape (expanded state) is assumed. At this time, a substantially rectangular parallelepiped housing space 20 is formed between the panels 11 to 16. Although not shown, a load such as food may be stored in the storage space 20.

  Next, as shown in FIG. 2, the front panel 12 is folded from the unfolded state by folding the front panel 12.

  During this time, first, the detachable member 35 is removed from the second side panel 15 as shown in FIG. Similarly, the detachable members 33 a to 33 d are removed from the top panel 11, and the detachable members 34 a to 34 d are detached from the bottom panel 16. Subsequently, the third front partial panel 12c is folded so as to overlap the second front partial panel 12b. Specifically, the third front partial panel 12c rotates clockwise with respect to the second front partial panel 12b about the third front hinge member 22c in plan view.

  Subsequently, as shown in FIG. 9B, the second front partial panel 12b and the third front partial panel 12c overlap each other, and in this state, the second front partial panel 12b and the third front partial panel 12c are The second front hinge member 22b is rotated clockwise with respect to the first front partial panel 12a in plan view.

  Thereafter, as shown in FIG. 9C, the second front partial panel 12 b and the third front partial panel 12 c move around the outside of the first side frame 51. Specifically, the first front partial panel 12a rotates clockwise in plan view with respect to the first side panel 14 around the first front hinge member 22a. At this time, the first front partial panel 12a is located on the front side (Y direction minus side) with respect to the first side panel 14, and the second front partial panel 12b and the third front partial panel 12c are on the first side. It is located outside (X direction minus side) with respect to the frame 51. In this way, the front panel 12 is folded, and the front side of the transport carriage 10 is completely opened in the horizontal direction (X direction) (see FIG. 2). In addition, when a load is stored in the storage space 20, the load may be taken out from the front side in this state.

  Next, the bottom panel 16 is folded from the unfolded state by folding the bottom panel 16 (see FIG. 3). During this time, the detachable member 37 is first removed from the back panel 13. Next, the bottom panel 16 is rotated counterclockwise with respect to the first side frame 51 in front view. As a result, the bottom panel 16 is folded so as to overlap the inside (X direction plus side) of the first side frame 51 and is positioned around the inside of the first side frame 51. That is, the bottom panel 16 is arranged perpendicular to the horizontal plane (XY plane) (parallel to the YZ plane). In this case, the bottom panel 16 is attached to the first side frame 51 by a surface fastener (not shown).

  Next, by folding the bottom plate 58, the bottom plate 58 shifts from the unfolded state to the folded state (see FIG. 3). During this time, the bottom plate 58 rotates clockwise in front view with respect to the second side frame 52 and is folded so as to overlap the inside of the second side frame 52 (X direction minus side). Located around the inside. That is, the bottom plate 58 is arranged perpendicular to the horizontal plane (XY plane) (parallel to the YZ plane). In this case, the bottom plate 58 is attached to the second side frame 52 by fixing means (not shown).

  Subsequently, as shown in FIGS. 10A to 10C, the top panel 11 is folded from the unfolded state by folding the top panel 11.

  During this time, first, the detachable member 32 is removed from the second side panel 15 as shown in FIGS. Similarly, the detachable members 31 a to 31 d are detached from the back panel 13. Subsequently, the first top surface partial panel 11a is rotated counterclockwise in front view with respect to the first side panel 14 around the first top surface hinge member 21c, and the second top surface partial panel 11b is The first top surface partial panel 11a is rotated clockwise around the second top surface hinge member 21d in the front view.

  Subsequently, as shown in FIG. 10C, the second top surface partial panel 11 b moves to the inner periphery of the first side frame 51. Specifically, the first top surface partial panel 11a rotates clockwise in front view with respect to the first side panel 14 around the first top surface hinge member 21c, and the second top surface partial panel 11b The second top surface hinge member 21d is rotated clockwise with respect to the first top surface partial panel 11a in front view. Accordingly, the second top surface partial panel 11b is folded downward and arranged to hang from the first top surface partial panel 11a. At this time, the second top surface partial panel 11b is arranged around the inner side of the first side frame 51 and on the inner side (X direction plus side) with respect to the bottom panel 16.

  Next, as shown in FIGS. 11A and 11B, the back panel 13 is folded from the unfolded state by folding the back panel 13.

  In the meantime, first, the detachable member 36 is removed from the second side panel 15 as shown in FIGS. Next, the second back partial panel 13b is rotated counterclockwise in plan view with respect to the first back partial panel 13a with the first back hinge member 23a as the center. Thereby, the 2nd back surface partial panel 13b is folded so that it may overlap with the 1st back surface partial panel 13a, and is arranged on the outside (Y direction plus side) of the 1st back surface partial panel 13a. On the other hand, the first back partial panel 13a maintains the same position as the unfolded state even in the folded state.

  In this way, the six panels 11 to 16 of the transport carriage 10 are all folded. As described above, when the transporting carriage 10 is not used, the panels 11 to 16 can be folded, and the entire volume can be reduced and stored and transported as much as possible.

(Assembly of the carriage for transportation)
The method of assembling the transport carriage 10 can be performed in the reverse order of the disassembly method described above.

  That is, first, the reverse work of FIGS. 11 (a) and 11 (b) is started. That is, the rear panel 13 is changed from the folded state to the expanded state. Thereafter, the detachable member 36 is attached to the second side panel 15.

  Next, the reverse operation of FIGS. 10A to 10C is performed. That is, the top panel 11 is changed from the folded state to the expanded state. Thereafter, the detachable member 32 is attached to the second side panel 15, and the detachable members 31 a to 31 d are attached to the back panel 13.

  Next, the bottom plate 58 and the bottom panel 16 are changed from the folded state to the expanded state. Thereafter, the detachable member 37 is attached to the back panel 13.

  Subsequently, the reverse operation of FIGS. 9A to 9C is performed. That is, the front panel 12 is changed from the folded state to the unfolded state. Thereafter, the detachable member 35 is attached to the second side panel 15, and the detachable members 33a to 33d and the detachable members 34a to 34d are attached to the top panel 11 and the bottom panel 16, respectively.

  In this way, the assembly work of the panels 11 to 16 is completed. Then, it is confirmed visually whether each panel 11-16 is correctly attached. For example, as shown in FIG. 12 (a), in the visual confirmation part 28 formed between the detachable members 33c and 33d, the deviation between the front panel 12 and the top panel 11 is visually confirmed.

  As shown in FIG. 12A, in the visual confirmation unit 28, when there is no gap between the front panel 12 and the top panel 11, the front panel 12 and the top panel 11 are correctly assembled. It can be judged. On the other hand, as shown in FIG. 12B, in the visual confirmation unit 28, when there is a gap between the front panel 12 and the top panel 11, the front panel 12 and the top panel 11 are correctly assembled. It is thought that it is not. In this case, the assembly operation of the front panel 12 and the top panel 11 is performed again. The confirmation work is similarly performed for each of the visual confirmation units 28 provided around the detachable members 33a to 33d and 34a to 34d.

  As described above, according to the present embodiment, the visual confirmation unit 28 that can visually confirm the displacement between the front panel 12 and the top panel 11 is provided around the detachable members 33a to 33d. In addition, a visual confirmation unit 28 that can visually confirm the deviation between the front panel 12 and the bottom panel 16 is provided around the detachable members 34a to 34d. Thereby, by visually observing the end surfaces of the panels 11, 12, and 16, it is determined whether or not the panels 11, 12, and 16 are correctly assembled so as not to deteriorate when the panels 11 to 16 are assembled. It can be confirmed easily and reliably.

  Moreover, according to this Embodiment, the visual confirmation part 28 is formed between the attachment / detachment members 33a-33d and 34a-34d which adjoin mutually. As a result, the operator visually confirms the contact state of the panels 11, 12 and 16 (whether there is a gap or a deviation) from between the detachable members 33 a to 33 d and 34 a to 34 d, and the panel is normally It can be determined whether 11, 12, and 16 are closed.

  Further, according to the present embodiment, the plurality of panels 11 to 16 can be in an unfolded state where they are unfolded and assembled in a box shape, and a folded state in which they can be nested with other transport carriages 10. Thereby, by making the panels 11-16 into an unfolded state, the accommodation space 20 which can accommodate a load and is highly airtight can be formed inside the panels 11-16. On the other hand, when the transport cart 10 is not used, the panels 11 to 16 are folded to be nested with other identical transport carts 10 to store these transport carts 10 in a compact manner. be able to.

(Modification)
Next, various modifications of the detachable member and the visual confirmation unit will be described with reference to FIGS. 13 to 22 are diagrams showing various modifications of the detachable member and the visual confirmation unit. In FIG. 13 to FIG. 22, the same parts are denoted by the same reference numerals and detailed description thereof is omitted. In each of the following modifications, a visual confirmation unit formed around some of the detachable members will be described as an example, but other visual confirmation units can be similarly configured.

(Modification 1)
FIGS. 13A and 13B show the visual confirmation unit 28A according to the first modification. As shown in FIGS. 13A and 13B, the detachable members 33c and 33d are connected to each other by a connecting piece 71 extending in the horizontal direction (X direction). Between the detachable members 33c and 33d, a visual confirmation unit 28A that can visually confirm the deviation between the front panel 12 and the top panel 11 is provided. In this visual confirmation part 28A, the boundary line between the front panel 12 and the top panel 11 is exposed.
