Description

[Technical Field]

[0001] The present invention relates to a loading truck. [Background technology]

[0002] For example, when transporting cargo such as containers, a platform truck is used to transport the cargo by placing it on the platform. The platform truck has, for example, a handle supported at the rear end of the platform so that it can be positioned in a use position and a folded position. With the platform truck, the user can transport the cargo placed on the platform by grasping and pushing the handle when the handle is positioned in the use position (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2023-8114 Summary of the Invention [Problem to be solved by the invention]

[0004] However, for example, when pushing the handle to transport heavy luggage on a platform cart, or when pushing the handle to transport luggage up a slope on a platform cart, a heavy burden is placed on the user pushing the handle, and therefore there is a need for practical application of technology that can reduce the burden when transporting luggage on a platform cart.

[0005] An object of the present invention is to provide a platform vehicle that can reduce the burden associated with transporting luggage. [Means for solving the problem]

[0006] In order to solve the above problems, the present invention proposes the following means. (1) The platform vehicle of the present invention comprises a platform having a loading surface for placing luggage, wheels provided on the platform opposite the loading surface, and a handle portion that can be positioned at one end of the platform in a usable position raised from the loading surface and in a folded position laid down along the platform, and further comprises a first support portion provided on either the wheel side or the side at the other end of the platform, a second support portion provided on either the wheel side or the side at the one end of the platform, and a towing portion that can be stored in the platform by being supported by the first support portion and the second support portion and can be pulled out from the platform to the other end side, and the towing portion has a handle portion that is positioned on the other end side of the first support portion when stored in the platform, and an engaging portion that can be hooked onto the platform when pulled out from the platform.

[0007] According to the above configuration, when the towing part is pulled out from the loading platform, the engaging part can be hooked onto (hooked onto) the loading platform. This towing part allows the user to pull the towing part when, for example, transporting heavy luggage placed on the loading platform using a loading platform truck, or when transporting luggage placed on the loading platform using a loading platform truck up a slope. This reduces the burden involved in transporting luggage compared to when pushing the handle of the loading platform truck to transport the luggage.

[0008] In addition, the towing unit can be stored in the loading platform, allowing the loading platform to be compact. This allows the loading platform to be stored in a small space.

[0009] (2) In the above aspect, the towing portion may be disposed on the one end side of the first support portion when stored in the loading platform, and may include a curved portion that protrudes toward the wheel.

[0010] With this configuration, the curved portion of the towing part protrudes toward the wheel. Therefore, when the towing part is pulled out from the cargo bed, the grip part of the towing part can be positioned above the cargo bed, making it easy for the user to grip the grip part.

[0011] (3) In the above aspect, a third support portion may be provided between the first support portion and the second support portion, and positioned on the first support portion side with respect to the curved portion when the towing unit is stored in the loading platform.

[0012] Here, the first support portion is provided at the other end of the loading platform, and the second support portion is provided at one end of the loading platform. Also, the curved portion of the towing portion protrudes toward the wheels. Therefore, when the towing portion is supported by the first support portion and the second support portion, it is conceivable that the curved portion will sway in the width direction of the loading platform. Therefore, when the towing unit is stored in the loading platform, the third support unit is located closer to the first support unit than the curved unit. This prevents the curved unit from swinging in the width direction of the loading platform by the third support unit. This allows the towing unit to be stored in a stable state in the loading platform.

[0013] Furthermore, by providing the third support part closer to the first support part than the curved part, there is no need to provide the third support part between the curved part and the engaging part. Therefore, the lengths of the curved part and the engaging part can be determined so that the handle is positioned at a position that is easy for the user to grasp when the towing part is pulled out from the cargo bed.

[0014] (4) In the above aspect, the gripping portion may have a locking portion that can be engaged with a receiving portion provided on the loading platform when the towing portion is stored in the loading platform, and the receiving portion may be provided at the other end on the side where the towing portion is pulled out relative to the first beam portion 36.

[0015] According to this configuration, the gripping part is provided with a locking part, and the loading platform is provided with a receiving part. The locking part can be locked with the receiving part. Therefore, when the towing part is stored in the loading platform, the locking part can be locked with the receiving part, thereby holding the gripping part with the receiving part. This allows the towing part to be stored in a stable state on the loading platform when, for example, pushing the handle of the loading platform to transport luggage. Furthermore, when storing the loading platform, the towing part can be stored in a stable state on the loading platform.

[0016] (5) In the above aspect, the engaging portion may have a stopper portion that can be hooked onto the loading platform when the towing portion is pulled out from the loading platform, and a recess that can engage with the second support portion when the towing portion is stored in the loading platform and can engage with the first support portion when the towing portion is pulled out from the loading platform.

[0017] The engaging portion has a stopper portion and a recess. The stopper portion can be hooked onto the loading platform when the towing portion is pulled out from the loading platform. This ensures that the traction force of the towing portion can be transmitted to the loading platform. This allows the loading platform to be transported reliably by the towing portion. Furthermore, the recess can engage with the first support part when the towing part is pulled out from the loading platform. This allows the towing part to be held in the pulled out state from the loading platform. This allows the loading platform to be transported reliably by the towing part. Furthermore, the recess can engage with the second support part when the towing part is stored in the cargo bed, thereby allowing the towing part to be stored in the cargo bed in a stable state. [Effects of the Invention]

[0018] According to the present invention, the burden of transporting luggage can be reduced. [Brief explanation of the drawings]

Hereinafter, the pair of front wheels 13, 13 may be abbreviated as "a pair of front wheels 13," and the pair of rear wheels 14, 14 may be abbreviated as "a pair of rear wheels 14." In addition, the direction in which a user pushes the handle portion 18 when transporting a container on the platform 10 will be described as the front, the left side of the user holding the handle portion 18 as the left side, and the side on which a container is loaded onto the platform 10 as the top. In the drawings, the front of the platform 10 is indicated by an arrow FR, the left side of the platform 10 by an arrow LH, and the top of the platform 10 by an arrow UP.

[0023] <Cargo bed> FIG. 3 is a perspective view of the carrier truck of the embodiment with the towing unit stored, as viewed from below on the left side. As shown in Figures 1 and 3, the loading platform 12 includes a loading platform main body 22, a loading plate (loading surface) 23, a pair of leg forks 24, 24, and a pair of legs 25, 25. The loading platform main body 22 includes a frame body 31, a pair of support portions 32, 33, and a loading platform lower portion 34. The frame body 31 is formed in a rectangular frame shape in a plan view. The pair of support portions 32, 33 are provided at the rear end of the frame body 31. The pair of support portions 32, 33 are formed symmetrically. The loading platform lower portion 34 is provided on the back surface of the frame body 31.

[0024] The bed lower portion 34 is provided on the opposite side of the loading plate 23 with respect to the bed main body 22. The bed lower portion 34 includes a first beam portion 36, a second beam portion 37, a third beam portion 38, and a fourth beam portion 39. The first beam portion 36 to the fourth beam portion 39 are bridged in the left-right direction on the rear surface of the frame body 31. The first beam portion 36 and the second beam portion 37 are provided at a distance from each other in the front-rear direction at the front end portion (other end portion) 22a of the bed main body 22.

[0025] A protruding portion 41 is provided on the first beam portion 36. The protruding portion 41 protrudes forward from the center of the first beam portion 36 in the left-right direction. A receiving portion 42 (see FIG. 7), which will be described later, is provided on the protruding portion 41. That is, the receiving portion 42 is provided on the loading platform 12 via the protruding portion 41. The receiving portion 42 will be described in detail later. The third beam portion 38 is provided in the center of the bed main body 22 in the front-rear direction. The fourth beam portion 39 is provided at the rear end portion (one end portion) 22b of the bed main body 22.

[0026] A loading plate 23 is attached to the bed body 22. The loading plate 23 is fixed to the bed body 22 with a plurality of bolts (not shown). Cargo such as containers is placed on the loading plate 23 from above. The loading plate 23 has a plurality of through holes 44 that penetrate in the up-down direction across the entire area. By drilling the plurality of through holes 44 in the loading plate 23, for example, when the loading plate 23 is washed with water, the water used to wash the upper surface of the loading plate 23 can flow below the loading plate 23 through the plurality of through holes 44.

[0027] The pair of leg forks 24, 24 are rotatably supported via support shafts (not shown) on left and right portions of the first beam portion 36 and the second beam portion 37. That is, the pair of leg forks 24, 24 are provided on the bed lower portion 34. The pair of leg forks 24, 24 each rotatably support a front wheel 13.

[0028] A pair of legs 25, 25 are provided on the left and right sides of the underside of the bed main body 22. The legs 25 are formed in a roughly V-shape in a side view. The front end 25a of the leg 25 is fixed to the third beam portion 38. The rear end 25b of the leg 25 is fixed to the rear end 22b of the bed main body 22. The lower end 25c of the leg 25 is disposed below the rear end 22b of the bed main body 22. A rear axle 46 is spanned across the lower end 25c of the pair of legs 25, 25 (only the right lower end 25c is shown) and extends in the left-right direction.

[0029] That is, the rear axle 46 is provided at the rear end 22b of the bed body 22 on the opposite side of the loading plate 23 (i.e., below the rear end 22b). The left and right ends of the rear axle 46 protrude outward on the left and right sides from the pair of lower ends 25c, 25c, respectively. The left and right ends of the rear axle 46 rotatably support the rear wheels 14, respectively.

[0030] <Front wheel> The pair of front wheels 13 are rotatably supported by a pair of leg forks 24, 24. The pair of leg forks 24, 24 are provided on a first beam portion 36 and a second beam portion 37 of the bed lower portion 34. The first beam portion 36 and the second beam portion 37 are provided on the opposite side of the loading plate 23 with respect to the bed main body 22. Therefore, the pair of front wheels 13 are provided on the front end portion 22a of the bed main body 22 opposite the loading plate 23 (i.e., below the front end portion 22a).

[0031] <Rear wheel> The pair of rear wheels 14 are rotatably supported on the left and right ends of a rear axle 46. The rear axle 46 is provided on the rear end 22b of the bed body 22 on the opposite side of the loading plate 23 (i.e., below the rear end 22b). Therefore, the pair of rear wheels 14 are provided on the rear end 22b of the bed body 22 on the opposite side of the loading plate 23 (i.e., below the rear end 22b).

[0032] <Connection> As shown in Figures 1 and 2, a pair of connecting parts 15, 16 are attached to the pair of support parts 32, 33, respectively. The pair of connecting parts 15, 16 are formed symmetrically. The rear end surfaces of the pair of connecting parts 15, 16 and the rear end surfaces of the pair of rear wheels 14 are arranged on the same plane PL at an interval on both sides of the loading platform 12 in a direction intersecting (in this embodiment, perpendicular or nearly perpendicular) the surface of the loading plate 23. A handle part 18 is attached to the left connecting part 15 and the right connecting part 16.

[0033] <Handle section> The handle portion 18 includes a pair of vertical pipes 51 and a grip portion 52. The pair of vertical pipes 51 are supported by support pins 53 (only the left support pin 53 is shown) at the left connecting portion 15 and the right connecting portion 16 so as to be rotatable forward and upward. A grip portion 52 is provided at the tip of the left vertical pipe 51 and the tip of the right vertical pipe 51. The handle portion 18 is integrally formed in a U-shape by the pair of vertical pipes 51 and the grip portion 52.

[0034] The handle portion 18 is supported so as to be able to be positioned at a use position P1 or a folded position P2 (see also FIG. 9 ) around a pair of support pins 53. The use position P1 is a position where the handle portion 18 is raised upward from the loading plate 23 at the rear end of the cargo bed 12. The folded position P2 is a position where the handle portion 18 is reclined along the loading plate 23 of the cargo bed 12. When the handle 18 is disposed at the use position P1, it is held at the use position P1 by the operation bar 55. When the handle 18 is disposed at the use position P1, the grip 52 is held at the height of the user's waist, for example. Therefore, the user can move the platform cart 10 forward by holding the grip 52 in their hand.

[0035] <Traction unit> FIG. 4 is an enlarged perspective view of part IV in FIG. 3 and 4, the towing unit 20 is provided on the bed lower portion 34 of the bed main body 22. The towing unit 20 includes a first support portion 61, a second support portion 62, a third support portion 63, and a towing portion (handle) 65.

[0036] The first support portion 61 is provided at the center 36a in the left-right direction of the first beam portion 36. The first support portion 61 protrudes from the center 36a of the first beam portion 36 toward the opposite side of the loading plate 23 (i.e., toward the bottom of the bed main body 22). The first beam portion 36 is provided at the front end portion 22a of the bed main body 22. Therefore, the first support portion 61 is provided on the side of the pair of front wheels 13 and the pair of rear wheels 14 at the front end portion 22a of the bed main body 22. Hereinafter, "the side of the pair of front wheels 13 and the pair of rear wheels 14" may be abbreviated as "the wheel 13, 14 side."

[0037] The first support portion 61 is formed, for example, by bending a rod. The first support portion 61 has a pair of fixing portions 66, 66 and a first recessed portion 67. The pair of fixing portions 66, 66 are fixed to the first beam portion 36. The first recessed portion 67 is formed in a substantially U-shape in a front view seen from the front. The first recessed portion 67 forms a space 68 together with the first beam portion 36. The space 68 is formed so that a traction rod 74 of the traction portion 65, which will be described later, can be inserted therethrough.

[0038] FIG. 5 is an enlarged perspective view of the V portion of FIG. 3 and 5, the second support portion 62 is provided at the center in the left-right direction at the rear end portion 22b of the bed body 22. The second support portion 62 protrudes from the center of the rear end portion 22b toward the opposite side of the loading plate 23 (i.e., toward the bottom of the bed body 22). Therefore, the second support portion 62 is provided on the wheels 13, 14 side at the rear end portion 22b of the bed body 22.

[0039] The second support portion 62 is formed, for example, by bending a rod. The second support portion 62 has a pair of inclined portions 71, 71 and a second recessed portion 72. The pair of inclined portions 71, 71 have base ends 71a fixed to the rear end portion 22b of the loading platform main body 22 with a gap between them in the left-right direction. The pair of inclined portions 71, 71 are formed in a V-shape inclined so that their width gradually decreases toward their tip ends 71b in a front view from the front. The tip ends 71b of the pair of inclined portions 71, 71 are provided with the second recessed portion 72.

[0040] Like the first recess 67, the second recess 72 is formed in a substantially U-shape in a front view. The second recess 72 has an opening 72a. The opening 72a of the second recess 72 is open to the tip end 71b of the pair of inclined portions 71. Therefore, the traction rod 74 of the traction portion 65, which will be described later, can be guided to the opening 72a of the second recess 72 by the pair of inclined portions 71. This allows the traction rod 74 to be smoothly accommodated (placed) in the opening 72a of the second recess 72.

[0041] The third support portion 63 is provided at the center 39a of the fourth beam portion 39 in the left-right direction. The third support portion 63 is provided between the first support portion 61 and the second support portion 62 in the front-rear direction and is located on the wheel 13, 14 side. Specifically, when the traction portion 65 is stored in the wheel 13, 14 side of the bed main body 22, the third support portion 63 is located on the first support portion 61 side with respect to a curved portion 83 (described later) of the traction rod 74. The third support portion 63 protrudes from the center 39a of the fourth beam portion 39 toward the opposite side of the load plate 23 (i.e., the wheel 13, 14 side). Therefore, when the traction rod 74 is stored in the wheel 13, 14 side of the bed main body 22, the third support portion 63 is located on the wheel 13, 14 side with respect to the curved portion 83 (described later).

[0042] The third support portion 63 is formed, for example, by bending a strip-shaped steel plate. The base end portion 63a of the third support portion 63 is fixed to the fourth beam portion 39 with a gap in the left-right direction. The third support portion 63 is formed in a substantially V-shape when viewed from the front. The traction rod 74 can be stored (placed) in the bottom portion 63b of the third support portion 63.

[0043] FIG. 6 is a side view of the platform truck of the embodiment with the towing section pulled out, as seen from the left side. 3 and 6, the towing unit 65 is supported by the first support unit 61, the second support unit 62, and the third support unit 63, and thereby can be stored on the wheel 13, 14 side of the bed body 22 (i.e., the bed 12). In addition, the towing unit 65 can be pulled out from the wheel 13, 14 side toward the front end 22a of the bed body 22 (i.e., forward) by releasing the support from the second support unit 62. The towing unit 65 includes a towing rod 74, a grip unit 75, and an engagement unit 76.

[0044] The traction rod 74 is formed, for example, by a hollow rod. The traction rod 74 has a first straight portion 81, a second straight portion 82, and a curved portion 83. The first straight portion 81 extends linearly from the front end 81a to the curved portion 83. The second straight portion 82 extends linearly from the curved portion 83 to the rear end 82a. The length of the second straight portion 82 from the rear end 82a of the second straight portion 82 to the curved portion 83 is L1. The length L1 of the second straight portion 82 is approximately the same as the distance L2 between the first support portion 61 and the front end 22a of the bed main body 22, for example, in the front-to-rear direction.

[0045] The first straight portion 81 and the second straight portion 82 are bent at the curved portion 83. Therefore, the towing rod 74 is formed into a substantially V-shape (or a substantially L-shape) by the first straight portion 81, the second straight portion 82, and the curved portion 83. When the towing portion 65 is stored on the wheel 13, 14 side of the bed main body 22, the curved portion 83 is located closer to the rear end 22b of the bed main body 22 than the first support portion 61 and the third support portion 63. The curved portion 83 also protrudes closer to the wheels 13, 14 than the front end 81a of the first straight portion 81 and the rear end 82a of the second straight portion 82. When the towing portion 65 is stored on the wheel 13, 14 side of the bed main body 22, for example, the curved portion 83 is located above the rear axle 46 (i.e., closer to the rear end 22b of the bed main body 22). In the above embodiment, an example is described in which the traction rod 74 is bent in a bent shape at the bent portion 83, but the bent portion 83 is not limited to being bent. As another example, the bent portion 83 may be bent into another shape, such as a curved shape.

[0046] Fig. 7 is a perspective view of the grip part of the towing part of the embodiment, seen from the lower left side, when separated from the body of the loading platform. Fig. 8 is a side view of the grip part of the towing part of the embodiment, seen from the left side. As shown in Figures 4, 7, and 8, the gripping part 75 is fixed to the front end 81a of the first straight part 81 with a bolt 85 and a nut (not shown). When the towing part 65 is stored on the wheel 13, 14 side of the bed body 22, the gripping part 75 is disposed on the front end 22a side of the bed body 22 with respect to the first support part 61. The gripping part 75 includes a handle 87 and a locking part 88. The handle 87 is the part that is grasped (i.e., held) by the user. By pulling the towing part 65 while grasping the handle 87, the user tows the bed cart 10 forward with the towing part 65.

[0047] The locking portion 88 protrudes from the rear end 75a of the grip portion 75 toward the bed body 22 when the towing portion 65 is stored on the wheel 13, 14 side of the bed body 22. The locking portion 88 is fixed to a nut (not shown). When the towing portion 65 is stored on the wheel 13, 14 side of the bed body 22, the locking portion 88 can be locked by being fitted into the receiving portion 42. The receiving portion 42 is provided on the protruding portion 41. The protruding portion 41 protrudes forward from the center in the left-right direction of the first beam portion 36. The first beam portion 36 is also provided on the front end portion 22a of the bed body 22.

[0048] Therefore, the receiving portion 42 is provided at the front end portion 22a of the bed body 22, forward of the first beam portion 36 (i.e., on the side where the towing portion 65 is pulled out). The receiving portion 42 has a guide portion 91 and a groove portion 92. The guide portion 91 is formed in a V-shape with an open front end 91a and a gradually narrowing width toward the groove portion 92 at the rear. The groove portion 92 is open at the rear end 91b of the guide portion 91. The groove 92 extends rearward. The locking portion 88 is locked into the groove 92. When the towing unit 65 is stored on the wheel 13, 14 side of the bed body 22, the locking portion 88 is guided by the guide portion 91 and properly fitted into the groove 92.

[0049] 3, 5, and 6, an engaging portion 76 is provided at the rear end 82a of the second straight portion 82. The engaging portion 76 can be hooked onto the first beam portion 36 when the towing portion 65 is pulled out from the wheel 13, 14 side of the bed body 22. The engaging portion 76 can be supported by the second support portion 62 when the towing portion 65 is stored on the wheel 13, 14 side of the bed body 22.

[0050] The engaging portion 76 includes a stopper portion 94 and an engaging recess (recess) 95. The stopper portion 94 is fixed to the rear end portion 82a of the second straight portion 82. The stopper portion 94 is disposed along the bending direction of the curved portion 83 of the traction rod 74 so as to intersect (in the embodiment, perpendicular to) the second straight portion 82. The stopper portion 94 has a first stopper 94a and a second stopper 94b. The first stopper 94a protrudes from the rear end portion 82a of the second straight portion 82 to the side opposite the curved portion 83. The first stopper 94a can be hooked to the first beam portion 36 when the traction portion 65 is pulled out from the wheel 13, 14 side of the bed main body 22.

[0051] The second stopper 94b protrudes from the rear end 82a of the second straight portion 82 toward the curved portion 83. A rod 96 is fixed to the rear end 82a in front of the second stopper 94b, facing in the left-right direction. The rod 96 is fixed forward of and spaced apart from the second stopper 94b. Therefore, an engagement recess 95 is formed by the second stopper 94b and the rod 96. The engagement recess 95 is engageable with the bottom 72b of the second recess 72 when the towing part 65 is stored on the wheel 13, 14 side of the bed main body 22. The second recess 72 is provided in the second support part 62. Furthermore, the engaging recess 95 can engage with the bottom 67a (see FIG. 4) of the first recess 67 when the towing part 65 is pulled out from the wheel 13, 14 side of the bed main body 22. The first recess 67 is provided in the first support part 61.

[0052] As described above, according to the loading platform 10 of the first embodiment, as shown in Fig. 6, when a user transports luggage on the loading platform 10 by pulling the towing part 65, the towing part 65 is pulled forward from the wheel 13, 14 side of the loading platform main body 22. With the towing part 65 pulled out from the wheel 13, 14 side of the loading platform main body 22, the first stopper 94a (see also Fig. 5) of the engaging part 76 can be latched (hooked) onto the first beam part 36 of the loading platform main body 22 from behind.

[0053] Furthermore, the curved portion 83 of the traction rod 74 protrudes toward the wheels 13, 14, forming the traction rod 74 into a substantially V-shape (or a substantially L-shape). Therefore, when the traction portion 65 is pulled out from the wheel 13, 14 side of the bed body 22, the second straight portion 82 of the traction rod 74 is positioned along the bed body 22, so that the grip portion 75 of the traction portion 65 can be positioned above the bed 12. This allows the handle 87 of the grip portion 75 to be positioned (particularly at a height) that is easy for a user to grip.

[0054] With this towing unit 65, for example, when transporting heavy luggage placed on the loading platform 12 with the loading platform 12 by the loading platform 10, or when transporting luggage placed on the loading platform 12 up a slope with the loading platform 12 by the loading platform 10, the user can pull the towing unit 65 to transport the luggage. This reduces the burden involved in transporting the luggage compared to when transporting the luggage by pushing the handle unit 18 of the loading platform 10.

[0055] FIG. 9 is a side view showing the state in which the carrier of the embodiment is stored by leaning it upright. As shown in Figure 9, the towing unit 65 can be stored on the wheel 13, 14 side of the bed body 22. This allows the bed vehicle 10 to be compact. In addition, the rear end faces of the pair of connecting parts 15, 16 of the bed 12 and the rear end faces of the pair of rear wheels 14 are arranged on the same plane PL (see Figure 2) at an interval on both sides of the bed body 22 in a direction perpendicular or approximately perpendicular to the loading plate 23 (see Figure 1). Therefore, the rear end faces of the pair of connecting portions 15, 16 and the rear end faces of the pair of rear wheels 14 can be brought into contact with the floor surface 100 or the like, thereby making it possible to lean the platform 10 upward. This makes it possible to keep the space required to store the platform 10 small when storing it.

[0056] 3, the first support portion 61 is provided at the front end 22a of the bed body 22. The second support portion 62 is provided at the rear end 22b of the bed body 22. The curved portion 83 of the pulling portion 65 protrudes toward the wheels 13, 14 of the bed body 22 relative to the front end 22a and the rear end 22b. Therefore, when the pulling portion 65 is supported by the first support portion 61 and the second support portion 62, it is conceivable that the curved portion 83 will swing left and right (widthwise) of the bed body 22. Therefore, when the towing part 65 is stored on the wheel 13, 14 side of the bed body 22, the third support part 63 is provided on the first support part 61 side of the curved part 83. Therefore, the third support part 63 can prevent the curved part 83 from swinging in the left-right direction of the bed body 22. This allows the towing part 65 to be stored in a stable state on the wheel 13, 14 side of the bed body 22.

[0057] 3 and 6, by providing the third support portion 63 closer to the first support portion 61 than the curved portion 83, there is no need to provide the third support portion 63 between the curved portion 83 and the engaging portion 76. Therefore, the length L1 of the second straight portion 82 can be determined so that the grip portion 75 is positioned at an easy-to-grasp position for a user when the towing portion 65 is pulled out from the cargo bed main body 22.

[0058] 2, 7, and 8, a locking portion 88 is provided on the gripping portion 75, and a receiving portion 42 is provided on the bed body 22. The locking portion 88 can be locked to the receiving portion 42. Therefore, when the towing portion 65 is stored on the wheel 13, 14 side of the bed body 22, the locking portion 88 can be locked to the receiving portion 42, thereby holding the gripping portion 75 on the receiving portion 42. As a result, for example, when pushing the handle portion 18 of the bed cart 10 to transport luggage, the towing portion 65 can be stored in a stable state on the wheel 13, 14 side of the bed body 22. Furthermore, as shown in FIG. 9, when the loading platform 10 is stored by leaning it upright, the towing part 65 can be stored in a stable state on the side of the wheels 13, 14 of the loading platform body 22.

[0059] 5 and 6, the engaging portion 76 has a stopper portion 94 and an engaging recess 95. The stopper portion 94 can be hooked onto the first beam portion 36 when the towing portion 65 is pulled out from the wheel 13, 14 side of the bed body 22. This ensures that the traction force of the towing portion 65 is transmitted to the bed 12. This ensures that the bed cart 10 can be transported reliably by the towing portion 65.

[0060] Furthermore, the engaging recess 95 can engage with the bottom 67a (see FIG. 4) of the first recess 67 of the first support part 61 when the towing part 65 is pulled out from the wheel 13, 14 side of the bed body 22. Therefore, the towing part 65 can be held in a state where it is pulled out from the wheel 13, 14 side of the bed body 22. This allows the loading platform 10 to be transported reliably by the towing part 65.

[0061] 3, 5, and 9, the engaging recess 95 can engage with the bottom 72b of the second recess 72 of the second support part 62 when the towing part 65 is stored on the wheel 13, 14 side of the bed main body 22. This allows the towing part 65 to be stored in a stable state on the wheel 13, 14 side of the bed main body 22 when pushing the handle part 18 of the bed cart 10 to transport luggage or when storing the bed cart 10 by leaning it upright.

[0062] The technical scope of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention. For example, in the above embodiment, an example has been described in which the first support portion 61, the second support portion 62, and the third support portion 63 are provided on the sides of the pair of front wheels 13 and the pair of rear wheels 14 in the loading platform main body 22, but this is not limitative. As another example, the first support portion 61, the second support portion 62, and the third support portion 63 may be provided on the side of the frame body 31 (side side) in the loading platform main body 22.

[0063] In addition, within the scope of the spirit of the present invention, the components in the above-described embodiments may be replaced with well-known components as appropriate, and the above-described modifications may be combined as appropriate. [Explanation of symbols]
