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 second side panel and the attachment member as seen from the front 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 has a pair of vertical hooks 55 extending in the vertical direction (Z direction) and a plurality of horizontal bars extending in the horizontal direction (Y direction) between the pair of vertical hooks 55. And a crosspiece 56. 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. The first side frame 51 may be connected to the wheel mounting frame 69 only by the central connection rod 54 without being directly connected to the wheel mounting frame 69.

  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.

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.

On the other hand, in the folded state (FIG. 3), the second back partial panel 13b is folded so as to overlap the first back partial panel 13a, and is disposed on the outer side (Y direction plus side) than the first back partial panel 13a. The At this time, the first back partial panel 13a remains on the back side without being folded. That is, the first back partial panel 13a is in the same position as in the unfolded state even in the folded state, and is arranged perpendicular to the horizontal plane (XY plane) (parallel to the ZX plane). Further, the first back surface partial panel 13a and the second back surface partial panel 13b are folded and arranged perpendicular to the first side frame 51, and are parallel to the ZX plane. Thus, in the folded state, the back panel 13 is opened by removing the second back partial panel 13b. The portion where the back panel 13 is opened has a predetermined width in the horizontal direction (X direction) (FIG. 3). Note that the back panel 13 may be opened across the entire horizontal direction (X direction) depending on how the first back partial panel 13a and the second back partial panel 13b are folded.

  Further, the second rear partial panel 13b of the rear panel 13 is detachably connected to the adjacent second side panel 15 by a detachable member (surface fastener) not shown. Further, the back panel 13 is detachably connected to an adjacent bottom panel 16 by a detachable member (surface fastener) (not shown).

It is arranged vertically (parallel to the YZ plane). The second side panel 15 is composed of a single plate-like member. In addition, the second side panel 15 is disposed around the outer side of the second side frame 52 of the carriage main body 50 without moving in both the unfolded state (FIG. 1) and the folded state (FIG. 3), and is in the YZ plane. It is parallel. The second side panel 15 is large enough to cover the entire outside of the second side frame 52.

  The second side panel 15 is fixed to the outside (X direction plus side) of the second side frame 52, and is attached to the second side frame 52 by an attachment member 81. A plurality of (four) attachment members 81 are attached to the second side panel 15, two at the upper part (Z direction plus side) of the second side panel 15, and the lower part (Z direction minus) of the second side panel 15. Two are arranged on the side). Specifically, the two attachment members 81 are detachably attached to the uppermost horizontal beam 56 of the second side frame 52, and the two attachment members 81 are attached to the lowermost side frame of the second side frame 52. Removably attached to the crosspiece 56.

  As shown in FIG. 6, the attachment member 81 is formed of a flexible string-like member. Specifically, the attachment member 81 includes a pair of cloth pieces 82a and 82b fixed to the main surface on the minus side in the X direction of the second side panel 15 by sewing or the like. Each attachment member 81 includes one hook-and-loop fastener (hook part or loop part) 83a attached to one cloth piece 82a and the other hook-and-loop fastener (loop part or hook part) attached to the other cloth piece 82b. ) 83b. The pair of cloth pieces 82a and 82b are respectively arranged above and below the horizontal rail 56, and the pair of hook-and-loop fasteners 83a and 83b are brought into close contact with each other, whereby the attachment member 81 is attached to the horizontal rail 56. The pair of hook-and-loop fasteners 83a and 83b are separated from each other, and the pair of cloth pieces 82a and 82b are separated from the horizontal rail 56 (imaginary line in FIG. 6), whereby the attachment member 81 is removed from the horizontal rail 56. In this way, the second side panel 15 is detachably attached to the crosspiece 56 of the second side frame 52 using the attachment member 81. Note that the attachment member 81 may be attached to a part of the second side frame 52. That is, the attachment member 81 is not limited to the horizontal rail 56 but may be detachably attached to the vertical rod 55 or the central connecting rod 54. Moreover, the attachment member 81 does not necessarily need to be fixed (adhered) to the second side panel 15 and may be detachably attached to the second side panel 15 by, for example, a hook-and-loop fastener.

(Bottom panel)
The bottom panel 16 is a panel located on the bottom surface side (minus side in the Z direction) in the unfolded state (FIG. 1), and is arranged in parallel to the horizontal plane (XY plane). In the unfolded state, the bottom panel 16 is disposed on the bottom plate 58 of the cart body 50 and between the first side frame 51 and the second side frame 52. The bottom panel 16 is composed of a single plate-like member and has a structure that can be folded by lifting. The bottom panel 16 is foldably attached to the first side frame 51 via a bottom hinge member (not shown).

  The bottom panel 16 is arranged in parallel to the horizontal plane (XY plane) in the unfolded state (FIG. 1). On the other hand, in the folded state (FIG. 3), the bottom panel 16 is folded so as to overlap the inner side (X direction plus side) of the first side frame 51 and is positioned around the inner side of the first side frame 51. That is, in the folded state, the bottom panel 16 is arranged perpendicular to the horizontal plane (XY plane) (parallel to the YZ plane). At this time, the bottom panel 16 is detachably attached to the first side frame 51 through, for example, a surface fastener (not shown).

  The top hinge member 21a, the first front hinge member 22a, the second front hinge member 22b, the third front hinge member 22c, the first rear hinge member 23a, the second rear hinge member 23b, and the bottom hinge member (see FIG. (Not shown) may be composed of, for example, a foldable connecting cloth (connecting member). Thus, each panel (partial panel) can be easily expand | deployed and folded by comprising each hinge member 21a, 22a, 22b, 22c, 23a, 23a, 23b, 26a from a connection cloth.

  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.

(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 period, first, as shown in FIG. 9A, 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 first front partial panel 12a centering on the second front hinge member 22b. Rotate clockwise 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). At this time, 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 period, first, as shown in FIGS. 10A and 10B, the first top surface partial panel 11a is counterclockwise in front view with respect to the first side panel 14 with the first top surface hinge member 21c as the center. The second top surface partial panel 11b rotates clockwise around the second top surface hinge member 21d with respect to the first top surface partial panel 11a in a 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.

  During this time, first, as shown in FIGS. 11A and 11B, the second back partial panel 13b rotates counterclockwise in plan view with respect to the first back partial panel 13a around the first back hinge member 23a. To do. 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. 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. Next, the bottom plate 58 and the bottom panel 16 are changed from the folded state to the expanded state. Finally, as the reverse operation of FIGS. 9A to 9C, the assembly operation is completed by changing the front panel 12 from the folded state to the expanded state.

  As described above, according to the present embodiment, the plurality of panels 11 to 16 can be in an unfolded state in which they are unfolded and assembled in a box shape, and in a folded state in which they can be nested with other carriages 10. it can. 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. As described above, the folding work and the assembling work of the panels 11 to 16 can be easily performed.

  Further, according to the present embodiment, the first side panel 14 is detachably attached to the first side frame 51 by an attachment member (not shown), and the second side panel 15 is secondly attached by the attachment member 81. The side frame 52 is detachably attached. As a result, the first side panel 14 and the second side panel 15 can be reliably fixed to the carriage body 50.

  Further, according to the present embodiment, the attachment member 81 includes a pair of hook-and-loop fasteners 83a and 83b that are detachably attached to the first side frame 51 or the second side frame 52. Thereby, while being able to fix the 1st side panel 14 and the 2nd side panel 15 to the trolley body 50 reliably, the 1st side panel 14 and the 2nd side panel 15 can be easily removed from the trolley body 50 as needed. Can do. For example, when only the carriage main body 50 is used or when the panels 14 and 15 are replaced, the removal work of the panels 14 and 15 can be easily performed.

(Modification)
Next, with reference to FIG. 12 thru | or FIG. 29, the various modified examples of the trolley | bogie are demonstrated. 12 to 29 are diagrams showing various modifications of the transportation carriage. 12 to 29, the same portions are denoted by the same reference numerals, and detailed description thereof is omitted. 12 to 23, the second side panel 15 will be described as an example, but the first side panel 14 can be similarly configured.

(Modification 1)
12 and 13 (a) and 13 (b) show a transport carriage 10 according to the first modification. In FIG. 12, the second side panel 15 is attached to the outside of the second side frame 52 by an attachment member 81 </ b> A. In this case, the attachment member 81 </ b> A is composed of a cap fitted to the upper end of the second side frame 52. ing. The attachment member 81A made of this cap has a substantially rectangular parallelepiped box shape that opens downward (in the Z direction minus side). In addition, a pair (a plurality) of attachment members 81 </ b> A are fixed to the upper portion (Z-direction plus side) of the second side panel 15, and the pair of attachment members 81 </ b> A are connected to the pair of vertical hooks 55 of the second side frame 52. Removably fitted to the upper end.

  The attachment member 81 </ b> A may be attached to the second side panel 15 in a removable or impossible manner such as sewing or a hook-and-loop fastener. The material of the mounting member 81A is not particularly limited, such as resin, rubber, metal, etc., but is preferably made of a material having elasticity. In this case, the right and left wobbles of the second side panel 15 can be made difficult to occur by firmly fitting the attachment member 81A to the upper end of the vertical hook 55 while being somewhat elastically deformed.

  As shown in FIGS. 13A and 13B, the pair of attachment members 81A fixed to the second side panel 15 are fitted into the pair of vertical hooks 55 of the second side frame 52 from above, respectively. The two side panels 15 can be detachably attached to the second side frame 52.

  In this case, the second side panel 15 is firmly fixed to the second side frame 52 by its own weight by covering the vertical flange 55 of the second side frame 52 with the mounting member 81A made of a cap, and the displacement of the second side panel 15 is prevented. Hard to occur. In addition, when the attachment member 81A is elastic, the second side panel 15 is more stably attached to the second side frame 52 by covering the attachment member 81A with the vertical rod 55 of the second side frame 52 with elastic deformation. Can be attached to. For this reason, the second side panel 15 can be easily attached and detached, and the stability against misalignment of the second side panel 15 can be enhanced.

(Modification 2)
14 and 15 (a) and 15 (b) show a transport carriage 10 according to the second modification. In FIG. 14, the second side panel 15 is attached to the outside of the second side frame 52 by an attachment member 81B. In this case, the attachment member 81 </ b> B includes a fitting member that is fitted into the second side frame 52. The attachment member 81B made of this fitting member is made of a substantially reverse concave block-like member having an opening 84 on the lower side. In addition, a pair (a plurality) of attachment members 81 </ b> B are fixed to the upper and lower sides (Z direction) of the second side panel 15 with a space therebetween, and the pair of attachment members 81 </ b> B are formed by the vertical rod 55 and the horizontal rail 56. Each is detachably fitted into the formed gap.

  The attachment member 81B may be attached to the second side panel 15 in a removable or impossible manner such as sewing or a hook-and-loop fastener. The material of the attachment member 81B is not particularly limited, such as rubber, foaming agent, plastic, etc., but it is preferable to use a hard and somewhat flexible material. For example, an attachment member 81B made of a polystyrene foam material may be used, and the attachment member 81B may be made disposable. Thus, the second side panel 15 can be positioned and fixed at the correct position of the second side frame 52 by firmly fitting the attachment member 81B into the gap between the vertical rod 55 and the horizontal rail 56.

  As shown in FIG. 15 (a), the mounting member 81B does not need to fill the entire gap between the vertical rod 55 and the horizontal rail 56, and shifts vertically and horizontally (Z direction both sides and Y direction both sides) within the gap. Any shape is acceptable. Further, since the attachment member 81B has the lower opening 84, when the removable intermediate shelf 59 is provided in the first side frame 51 and the second side frame 52 (the phantom line in FIG. 14), this intermediate The shelf 59 can be prevented from interfering with the attachment member 81B. If there is not enough space to avoid the intermediate shelf 59, the vertical rod 55 and the horizontal rail are only in the three directions of the upper and left and right sides (Z direction plus side and both sides in the Y direction) within the gap between the vertical rod 55 and the horizontal rail 56. You may make it contact | connect the crosspiece 56 (FIG.15 (b)). In this case, a thin spacer (not shown) that does not interfere with the intermediate shelf 59, such as a thin metal piece, may be provided at the left and right lower ends (Y direction lower ends) of the mounting member 81B.

  The mounting member 81B is fixed with elastic deformation in the gap between the vertical bar 55 and the horizontal rail 56 by its elastic force. Since the attachment member 81B enters the gap between the vertical bar 55 and the horizontal rail 56 by elastic deformation, the second side panel 15 can be reliably positioned on the second side frame 52. Further, the attachment member 81B is not easily detached from the second side frame 52 due to elastic deformation, but the attachment member 81B can be detached from the second side frame 52 as necessary.

(Modification 3)
16 and 17 (a) and 17 (b) show a transport carriage 10 according to the third modification. In FIG. 16, the second side panel 15 is attached to the outside of the second side frame 52 by an attachment member 81. In this case, the attachment member 81 is made of a string-like member as in the above-described embodiment. It is configured (see FIG. 6). Further, the second side panel 15 is provided with a positioning member 85 for positioning with the second side frame 52. A plurality of (four) positioning members 85 are attached to the second side panel 15, specifically, two positioning members 85 a provided on both sides (Y direction both sides) of the second side panel 15, And two positioning members 85b provided above and below the side panel 15 (Z direction). Of these, the two left and right positioning members 85a restrict the movement of the second side panel 15 in the lateral direction (both sides in the Y direction), and the two upper and lower positioning members 85b are positioned downward (Z (Minus direction) is restricted. Since the second side panel 15 is difficult to move upward (Z direction plus side) due to its own weight, the upward movement of the second side panel 15 may not be restricted.

  The positioning member 85 may be attached to the second side panel 15 in a detachable or impossible manner such as sewing or a hook-and-loop fastener. The material of the positioning member 85 may be a material having some flexibility such as rubber, or may be a hard member such as hard plastic, metal, or carbon. The left and right positioning members 85a may be disposed outside the second side frame 52 (FIG. 17A) or may be disposed inside the second side frame 52 (FIG. 17B). .
