DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] A transport cart 10 according to this embodiment will be described with reference to the drawings. FIG. 1 is a perspective view showing an example of the configuration of the transport cart 10. FIG. 2 is a plan view showing an example of the configuration of the transport cart 10. FIG. 3 is a bottom view showing an example of the configuration of the transport cart 10. FIG. 4 is a side view showing an example of the configuration of the transport cart 10. In each drawing, the traveling direction of the transport cart 10 is the front-rear direction, and the front side is indicated as Fr, the rear side as Rr, the right side as R, and the left side as L. Therefore, the side view of FIG. 4 is a view seen from a side perpendicular to the traveling direction of the transport cart 10. Note that the transport cart 10 of this embodiment can travel in any direction including the front-rear, left-right, and front-rear directions, not limited to the front side.

[0009] The transport cart 10 comprises a cart main body 20 and a running section 70. First, the carriage body 20 will be described. The bogie main body 20 is formed by connecting a plurality of frame parts and the like. The bogie main body 20 is longer in the front-rear direction than in the left-right direction in a plan view, and has a rectangular shape consisting of a pair of long sides and a pair of short sides. The bogie main body 20 has a long side x short side size of, for example, 1920 mm x 910 mm. As shown in Figs. 2 and 3, the bogie main body 20 has a front frame part 21a, a rear frame part 21b, a right frame part 22a, a left frame part 22b, a corner member 30, reinforcing frame parts (reinforcing parts) 42a, 42b, 51a, 51b, and the like.

[0010] The front frame portion 21a and the rear frame portion 21b are arranged horizontally along the left-right direction. The front frame portion 21a and the rear frame portion 21b are in the shape of a long, straight rod, and may be, for example, a hollow pipe made of an aluminum alloy. The upper surfaces of the front frame portion 21a and the rear frame portion 21b are flat and serve as a loading surface when loading cargo onto the dolly body portion 20.

[0011] The right frame portion 22a and the left frame portion 22b are disposed horizontally along the front-rear direction. The right frame portion 22a and the left frame portion 22b have the same configuration, so only the right frame portion 22a will be described here. The right frame portion 22a is formed by connecting a plurality of frames. Specifically, the right frame portion 22a has a front end frame 23, a rear end frame 24, an intermediate frame 25, a first supported frame 26, a second supported frame 27, a spacer frame 28, and a connecting member 29.

[0012] The front end frame 23 and the rear end frame 24 are in the shape of a long, straight rod, and may be, for example, a hollow or solid pipe made of an aluminum alloy. The front end frame 23 and the rear end frame 24 are each arranged horizontally along the front-to-rear direction. The front end frame 23 is a frame located in front of the right frame portion 22a, and the rear end frame 24 is a frame located in rear of the right frame portion 22a. The intermediate frame 25 is a long, straight rod, and may be, for example, a hollow or solid pipe made of an aluminum alloy. The intermediate frame 25 is disposed horizontally along the front-rear direction. The intermediate frame 25 is a frame located on the central side of the right frame portion 22a. The intermediate frame 25 is also a frame located between the front end frame 23 and the rear end frame 24. The upper surfaces of the front end frame 23, the rear end frame 24, and the intermediate frame 25 are at substantially the same height from the floor surface. The upper surfaces of the front end frame 23, the rear end frame 24, and the intermediate frame 25 are flat and serve as loading surfaces when loading cargo onto the cart body 20.

[0013] The first supported frame 26 and the second supported frame 27 are in the form of a long, straight rod, and may be, for example, a hollow or solid pipe made of an aluminum alloy. The first supported frame 26 and the second supported frame 27 are arranged horizontally along the front-rear direction. The lower surfaces of the first supported frame 26 and the second supported frame 27 are at substantially the same height from the floor surface. The lengths of the first supported frame 26 and the second supported frame 27 in the front-rear direction are substantially the same, and are each longer than the width of the prongs (forks) of a forklift. The lower surfaces of the first supported frame 26 and the second supported frame 27 become supported parts that are supported by a pair of prongs when the transport cart 10 is lifted by the forklift.

[0014] The first supported frame 26 is a frame that is bridged between the front end frame 23 and the intermediate frame 25 at a position lower than the front end frame 23 and the intermediate frame 25. Specifically, the front end of the first supported frame 26 is connected to the rear end and lower side of the front end frame 23 via a spacer frame 28, and the rear end is connected to the front end and lower side of the intermediate frame 25 via the spacer frame 28. The first supported frame 26, the front end frame 23, the intermediate frame 25 and the spacer frame 28 are fixed using screws, rivets, etc., in a state where they are sandwiched from the left and right by connecting members 29 that are bent in a Z shape, for example.

[0015] The second supported frame 27 is a frame that is bridged between the intermediate frame 25 and the rear end frame 24 at a position lower than the intermediate frame 25 and the rear end frame 24. Specifically, the front end of the second supported frame 27 is connected to the lower rear end of the intermediate frame 25 via a spacer frame 28, and the rear end is connected to the lower front end of the rear end frame 24 via the spacer frame 28. The second supported frame 27, intermediate frame 25, rear end frame 24 and spacer frame 28 are fixed using screws, rivets, etc. in a state where they are sandwiched from the left and right by connecting members 29 that are bent in a Z shape, for example.

[0016] Corner member 30 is made of, for example, an aluminum alloy that is extruded and then post-processed. Corner member 30 has an insertion hole 31 that opens upward and a stopper portion 32 that closes the downward side. A hand push member 80, shown by the two-dot chain line in FIG. 1, can be inserted into insertion hole 31 of corner member 30. The lower end of hand push member 80 inserted into insertion hole 31 is supported by stopper portion 32. The hand push member 80 can be, for example, a straight pipe with a circular cross section made of iron or aluminum alloy, a so-called single pipe. The front frame portion 21a, the rear frame portion 21b, the right frame portion 22a, and the left frame portion 22b are joined at their four corners by corner members 30 to form a rectangular frame on all four sides.

[0017] The reinforcing frame parts 42a, 42b, 51a, 51b may be, for example, hollow aluminum alloy pipes with rectangular cross sections or plates with uneven cross sections. The reinforcing frame parts 42a, 42b, 51a, 51b are butted together in the front-rear and left-right directions within the four frame frames and are joined by screws, rivets, welding, or the like to reinforce the trolley body part 20. In this embodiment, the reinforcing frame parts 42a and 42b are arranged in the front-rear direction so as to span between the front frame part 21a and the rear frame part 21b. The reinforcing frame parts 42a and 42b are arranged in parallel at positions separated from each other in the left and right directions. Specifically, the reinforcing frame part 42a is arranged on the right frame part 22a side, and the reinforcing frame part 42b is arranged on the left frame part 22b side. The left-right distance between the reinforcing frame part 42a and the right frame part 22a and the left-right distance between the reinforcing frame part 42b and the left frame part 22b are substantially the same. On the other hand, the left-right distance between the reinforcing frame part 42a and the right frame part 22a and the left-right distance between the reinforcing frame part 42b and the left frame part 22b are shorter than the left-right distance between the reinforcing frame part 42a and the reinforcing frame part 42b. Since the reinforcing frame part 42a and the reinforcing frame part 42b have the same configuration, the reinforcing frame part 42a will be described here. Moreover, the reinforcing frame portion 42a has a configuration substantially similar to that of the right frame portion 22a, and therefore a description thereof will be omitted where appropriate.

[0018] As shown in FIG. 2, the reinforcing frame portion 42a has a front end reinforcing frame 43, a rear end reinforcing frame 44, a middle reinforcing frame 45, a first reinforcing frame 46, a second reinforcing frame 47, a spacer reinforcing frame 48, and a connecting member 29. The front end reinforcement frame 43 and the rear end reinforcement frame 44 have a similar configuration to the front end frame 23 and the rear end frame 24, except that their width in the left-right direction is smaller than that of the front end frame 23 and the rear end frame 24. The front end reinforcement frame 43 is joined to the front frame portion 21a, and the rear end reinforcement frame 44 is joined to the rear frame portion 21b. The intermediate reinforcing frame 45 has a similar configuration to the intermediate frame 25, except that its width in the left-right direction is smaller than that of the intermediate frame 25. The upper surfaces of the front-end reinforcement frame 43, the rear-end reinforcement frame 44, and the intermediate reinforcement frame 45 are at substantially the same height from the floor surface. The upper surfaces of the front-end reinforcement frame 43, the rear-end reinforcement frame 44, and the intermediate reinforcement frame 45 are flat and serve as loading surfaces when loading cargo onto the cart body 20.

[0019] The first reinforcing frame 46 and the second reinforcing frame 47 have a similar configuration to the first supported frame 26 and the second supported frame 27 except that their width dimensions in the left-right direction are smaller than those of the first supported frame 26 and the second supported frame 27. The spacer reinforcing frame 48 has a similar structure to the spacer frame 28, except that its width in the left-right direction is smaller than that of the spacer frame 28. The first reinforcement frame 46, the front end reinforcement frame 43, the intermediate reinforcement frame 45 and the spacer reinforcement frame 48 are clamped from the left and right by the connecting members 29 and fixed using screws, rivets, etc. The second reinforcement frame 47, the intermediate reinforcement frame 45, the rear end reinforcement frame 44 and the spacer reinforcement frame 48 are clamped from the left and right by the connecting members 29 and fixed using screws, rivets, etc.

[0020] The reinforcing frame parts 51a, 51b are in the shape of a long, straight rod, and may be, for example, a hollow or solid pipe made of an aluminum alloy, etc. The reinforcing frame parts 51a, 51b are arranged along the left-right direction. The reinforcing frame portion 51a is fixed using screws, rivets, etc. in a state in which it spans between the right frame portion 22a and the reinforcing frame portion 42a and between the left frame portion 22b and the reinforcing frame portion 42b. A plurality of the reinforcing frame portions 51a are arranged at intervals in the front-rear direction. On the other hand, the reinforcing frame portion 51b is fixed between the reinforcing frame portions 42a and 42b using screws, rivets, etc. A plurality of the reinforcing frame portions 51b are disposed at intervals in the front-rear direction. Furthermore, since the left-right distance between reinforcing frame portion 42a and right side frame portion 22a, and the left-right distance between reinforcing frame portion 42b and left side frame portion 22b are shorter than the left-right distance between reinforcing frame portion 42a and reinforcing frame portion 42b, the left-right length of reinforcing frame portion 51a is shorter than the left-right length of reinforcing frame portion 51b. Furthermore, among the reinforcing frame portions 51a, the reinforcing frame portion 51a fixed to the first supported frame 26 or the second supported frame 27 is lower in height than the other reinforcing frame portions 51a, in order to match the heights of the first supported frame 26 and the second supported frame 27. Similarly, among the reinforcing frame portions 51b, the reinforcing frame portion 51b fixed to the first reinforcing frame 46 or the second reinforcing frame 47 is lower in height than the other reinforcing frame portions 51b, in order to match the height of the first reinforcing frame 46 or the second reinforcing frame 47.

[0021] In this way, by joining the reinforcing frame portions 42a, 42b, 51a, and 51b within the frame, multiple rectangular spaces are formed that are divided into, for example, three rows in the front-to-back direction and, for example, seven rows in the left-to-right direction when viewed in a plan view as shown in Figure 2. The cart body 20 also has mounting plates 60A, 60B as mounting members. The mounting plates 60A, 60B mount the casters 71A, 71B to the underside of the cart body 20. Specifically, the mounting plate 60A is fixed to each frame portion and each reinforcing frame portion using screws, rivets, or the like so as to close the front and left-right spaces and the rear and left-right spaces from below. The mounting plate 60A is a rectangular metal plate made of, for example, an aluminum alloy, with the corners cut out. On the other hand, the mounting plate 60B is fixed to each frame portion and each reinforcing frame portion using screws, rivets, etc. so as to close the space in the center in the front-rear direction and on both sides in the left-right direction from below. Specifically, the mounting plate 60B is fixed so as to close the space surrounded by the intermediate frame 25 of the right frame portion 22a, the intermediate reinforcing frame 45 of the reinforcing frame portion 42a, and the two reinforcing frame portions 51a, and the space surrounded by the intermediate frame 25 of the left frame portion 22b, the intermediate reinforcing frame 45 of the reinforcing frame portion 42b, and the two reinforcing frame portions 51a. The mounting plate 60B is a metal plate made of, for example, an aluminum alloy, having a rectangular shape with adjacent corners cut out.

[0022] The running part 70 runs on the running surface while supporting the weight of the dolly body 20 and the load. The running part 70 has a plurality of casters 71A, 71B. As shown in FIG. 3, the running part 70 has six casters, including four casters 71A arranged at the four corners of the dolly body 20 and two casters 71B arranged at the center in the front-rear direction and spaced apart on the left and right. The casters 71A are attached to the dolly body 20 via a mounting plate 60A. Since the casters 71A are arranged at the four corners of the lower surface of the dolly body 20, the transport dolly 10 can run in a stable state. In addition, the casters 71B are attached to the dolly body 20 via a mounting plate 60B. Since the casters 71B are arranged at the center in the front-rear direction of the dolly body 20 and spaced apart on the left and right, the transport dolly 10 can run without tilting even if the load is unevenly loaded.

[0023] The casters 71A and 71B are rotatable about a rotation axis O which is a vertical axis. The caster 71A is a braked caster that can apply or release the brake according to the user's operation. Specifically, the caster 71A has a wheel 72, a fork member 73, and a brake pedal 74. The fork member 73 rotatably supports the wheel 72. The brake pedal 74 can swing up and down relative to the fork member 73. When the user operates the brake pedal 74 by stepping downward with his / her foot, the outer circumferential surface of the wheel 72 is pressed, and the wheel 72 is braked. The user can further step on the brake pedal 74 to hold the wheel 72 in a braked state. As shown in FIG. 2 and FIG. 3, a part or the whole of the brake pedal 74 of the caster 71A that is the rear side when the transport cart 10 is traveling is located rearward of the rear end of the rear frame portion 21b and exposed, so that the user can easily step on the brake pedal 74. On the other hand, the caster 71B disposed in the center is a caster without a brake. Specifically, the caster 71B has a wheel 72 and a fork member 73, but does not have a brake pedal.

[0024] Next, a configuration that allows lifting only the load or the entire transport cart without adjusting the distance between the pair of forklift claws will be described with reference to Fig. 4. In Fig. 4, a plane F obtained by extending the loading surface horizontally is shown by a two-dot chain line. Also, in Fig. 4, the connecting member 29 is omitted. In the transport cart 10 of this embodiment, the first supported frame 26 and the second supported frame 27 are located between the loading surface and the floor surface. In addition, the transport cart 10 has a space S1 that opens upward above the first supported frame 26 and the second supported frame 27 in a side view. In addition, the transport cart 10 has a space S2 below the first supported frame 26 and the second supported frame 27. In other words, the space S1 and the space S2 are located above and below the first supported frame 26 or the second supported frame 27 between the loading surface and the floor surface.

[0025] In the transport cart 10 of this embodiment, no parts are arranged in the space S1 and the space S2 from the right frame part 22a to the left frame part 22b in a side view. That is, even if the caster 71A and the caster 71B rotate around the rotation axis O, the rotation path when the caster rotates does not overlap with the space S1 and the space S2 in a side view. In Fig. 4, the rotation path when the caster 71A and the caster 71B are rotated is shown by a two-dot chain line. In addition, in the transport cart 10 of this embodiment, the height H1 of the space S1, i.e., the vertical distance from the upper surface of the first supported frame 26 to the loading surface and the vertical distance from the upper surface of the second supported frame 27 to the loading surface, are greater than the thickness of the tines of a forklift. In addition, in the transport cart 10 of this embodiment, the height H2 of the space S2, i.e., the vertical distance from the underside of the first supported frame 26 to the floor surface and the vertical distance from the underside of the second supported frame 27 to the floor surface, are greater than the thickness of the tines of a forklift. In the transport cart 10 of this embodiment, the height H1 of the space S1 and the height H2 of the space S2 are the same or approximately the same. Here, the combined error of manufacturing error and assembly error is included in the same range. Also, the difference in the height of the first supported frame 26 or the second supported frame 27 is included in the same range.

[0026] Furthermore, in the transport cart 10 of this embodiment, the distance L between the front space S1 and the rear space S1 and the distance L between the front space S2 and the rear space S2 are approximately equal to the distance between a pair of prongs of a forklift. In Fig. 4, L denotes the distance between the center position in the front-rear direction of the first supported frame 26 and the center position in the front-rear direction of the second supported frame 27.

[0027] 5 is a side view showing an example of a state in which a load is loaded onto the cart body 20. Here, a plurality of folded mobile work platforms 90 are loaded onto the loading surface as the load. With the transport cart 10 configured as described above, when it is desired to lift only the load with a forklift, a pair of claws are inserted from the sides (right or left) of the transport cart 10 into the spaces S1 located at the front and rear, respectively. At this time, since no parts of the transport cart 10 are arranged in the space S1 from the right frame portion 22a to the left frame portion 22b in a side view, the claws inserted into the space S1 do not come into contact with parts of the transport cart.

[0028] FIG. 6 is a side view showing an example of a state in which only a load is being lifted by a forklift. A pair of claws T of a forklift are inserted into the space S1, and then the pair of claws T are raised. Since the space S1 is open on the upper side, the raised claws T support only the load. Therefore, as shown in Figure 6, by raising the claws T of the forklift, only the load can be lifted.

[0029] On the other hand, when it is desired to lift the transport cart 10 loaded with a load using a forklift, a pair of claws T are inserted from the sides (right or left) of the transport cart 10 into the spaces S2 located at the front and rear, respectively. At this time, in a side view, no parts of the transport cart 10 are arranged in the space S2 from the right frame part 22a to the left frame part 22b. Specifically, the casters 71A and 71B are not arranged, including the turning trajectory. Therefore, the claws T inserted into the space S2 do not come into contact with parts of the transport cart 10.

[0030] FIG. 7 is a side view showing an example of a state in which the transport cart 10 is being lifted by a forklift. A pair of claws T of the forklift are raised from a state in which each of them is inserted into the space S2. Since the first supported frame 26 and the second supported frame 27 are arranged on the upper side of the space S2, the raised claws T support the lower surfaces of the first supported frame 26 and the second supported frame 27. Therefore, as shown in FIG. 7, the entire transport cart 10 can be lifted by raising the claws T of the forklift. The first supported frame 26 and the second supported frame 27 of the right frame portion 22a and the left frame portion 22b, respectively, are supported by the pair of claws T of the forklift. At this time, the first reinforcing frame 46 and the second reinforcing frame 47 of the reinforcing frame portions 42a, 42b, respectively, may also be configured to be supported by the claws T of the forklift.

[0031] Here, the spaces S1 and S2 are located above and below the first supported frame 26 and the second supported frame 27. Therefore, even when lifting only the load or when lifting the entire transport cart 10, there is no need to adjust the distance between the pair of claws T. For example, even when the load is lifted and transported immediately after the entire transport cart 10 is transported by a forklift, the transport work can be performed quickly because there is no need to adjust the distance between the pair of claws T.

[0032] In addition, it is preferable that the cargo to be loaded onto the trolley main body 20 in this embodiment is long, extending from the front frame portion 21a to the rear frame portion 21b, or that covers a wide area of ​​the trolley main body 20 from above. 8 is a side view showing an example of a state in which a plurality of plasterboards 95 are stacked and loaded as cargo on the dolly body 20. The plasterboards 95 are flat, with long sides and short sides measuring, for example, 1820 mm by 910 mm. In this way, even if the cargo is flat, it is possible to lift only the cargo by lifting a pair of claws of the forklift after inserting each of the claws into the space S1.

[0033] Thus, in this embodiment, the dolly body 20 has the first supported frame 26 and the second supported frame 27 as supported parts that are located between the loading surface and the floor surface and are supported by a pair of claws when the transport dolly 10 is lifted by a forklift. In a side view, the upper side of the first supported frame 26 and the second supported frame 27 has a space S1 that opens upward and into which a pair of claws of a forklift can be inserted from the side, and the lower side of the first supported frame 26 and the second supported frame 27 has a space S2 into which a pair of claws of a forklift can be inserted from the side. Therefore, even without adjusting the spacing between the pair of claws, only the load can be lifted by inserting the pair of claws into the space S1 and lifting it, and the transport dolly 10 can be lifted by inserting the pair of claws into the space S2 and lifting it.

[0034] In this embodiment, the caster 71A is attached to the front side away from the first supported frame 26 and the second supported frame 27, and the caster 71A is attached to the rear side. Therefore, when the pair of claws is inserted into the space S2, it is possible to prevent contact with the caster 71A. In this embodiment, an intermediate frame 25 is provided between the first supported frame 26 and the second supported frame 27 as an intermediate portion located above the first supported frame 26 and the second supported frame 27. By providing the intermediate frame 25, when the pair of claws is inserted into the space S2 to lift the transport cart 10, the intermediate frame 25 comes into contact with the load, and it is possible to prevent the first supported frame 26 and the second supported frame 27 from bending upward.

[0035] In this embodiment, in side view, the casters 71B are attached to the lower side of the intermediate frame 25. Therefore, the transport cart 10 can travel in a stable state. In addition, in the present embodiment, the space S2, including the turning trajectory, is positioned so as not to overlap the casters 71A and 71B in a side view. Therefore, when the pair of claws T are inserted into the space S2, it is possible to prevent the casters 71A and 71B from coming into contact with each other, regardless of the turning position of the casters 71A and 71B.

[0036] Although the present invention has been described above in conjunction with the above-mentioned embodiment, the present invention is not limited to the above-mentioned embodiment, and modifications and the like are possible within the scope of the present invention. In the above embodiment, the loading surface is the upper surface of the front frame portion 21a, the rear frame portion 21b, the right frame portion 22a, the left frame portion 22b, and the reinforcing frame portions 42a, 42b, 51a, and 51b, but this is not limited to the above case. For example, a flat loading plate may be fixed onto the frame portions and the reinforcing frame portions, and cargo may be loaded onto the loading plate. In this case, the loading plate is configured not to cover the space S1 from above. In the above embodiment, the running unit 70 has six casters 71A, 71B, but the present invention is not limited to this, and may have only four casters 71A. [Explanation of symbols]
