Description

[Technical field]

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

[0002] For example, when transporting luggage, a dolly is used to transport the luggage by placing it on a loading platform. In the dolly, for example, a handle portion is supported at the rear end of the loading platform so that it can be positioned in a use position and a folded position. The handle portion has a pair of vertical bars whose base ends are supported at the rear end of the loading platform and a handle portion is hung across the tip ends of the pair of vertical bars. The pair of vertical bars extend linearly, for example, from the base ends to the tip ends. When the handle portion is positioned in the use position, the pair of vertical bars are positioned at an upward incline rearward from the rear end of the loading platform (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2019-123348 A Summary of the Invention [Problem to be solved by the invention]

[0004] Here, in the conventional handle unit, when the handle unit is placed in the use position, the handle unit is hung on the upper ends of the pair of vertical bars. However, there are height differences among users who use the platform, and the handle unit may not be at an appropriate height for some users. For this reason, there is still room for improvement in terms of the convenience of the platform that can accommodate the height differences of users. Here, as a measure to accommodate the height differences of users, for example, it is conceivable to add a new handle unit below the existing handle unit.

[0005] However, the conventional handle portion has a pair of vertical bars that extend linearly from the base end to the tip end. Furthermore, when the handle portion is in the use position, the pair of vertical bars are arranged at an upward incline from the rear end of the platform toward the rear. Therefore, the existing handle portion is located above and rearward of the new handle portion. Therefore, when a user holds the new handle portion and transports luggage on the cart, the user's arm may interfere with the existing handle portion.

[0006] In addition, the new handle is located in front of the existing handle. In other words, it is considered that the new handle is too close to the platform of the cart. Therefore, when a user holds the new handle and transports luggage placed on the platform with the cart, for example, the user's legs (especially elbows) may interfere with the luggage. Therefore, if a new handle is added below an existing handle, the user's arms may interfere with the existing handle or the user's legs may interfere with the luggage, which is undesirable from the standpoint of convenience.

[0007] An object of the present invention is to provide a cart that can ensure convenience by accommodating differences in height among users. [Means for solving the problem]

[0008] In order to solve the above problems, the present invention proposes the following means. (1) The trolley of the present invention comprises a loading platform for carrying luggage, and a handle portion having a pair of vertical bars on both sides of the loading platform, the pair of vertical bars having first and second handle portions, the vertical bars having a first rising portion rising upward from the side of the loading platform, a sloping portion extending upward from the first rising portion to the opposite side of the loading platform, and a second rising portion rising upward from the sloping portion, the first handle portion being spanned across the pair of second rising portions, and the second handle portion being spanned below the first handle portion.

[0009] According to the above configuration, the vertical bar of the handle portion is provided with a first rising portion, an inclined portion, and a second rising portion. The first rising portion can be arranged vertically by raising it upward from the side of the loading platform portion. The inclined portion extends from the end of the first rising portion to the opposite side of the loading platform portion at an upward gradient. The second rising portion can be arranged vertically by raising it upward from the end of the inclined portion 42. Furthermore, a first handle portion is bridged across the pair of second rising portions that are raised vertically, and the second handle portion is bridged below the first handle portion.

[0010] Therefore, the second handle can be disposed at the same position as the first handle in the front-rear direction, which can prevent, for example, the user's arm from interfering with the first handle when the user holds the second handle in his / her hand to transport luggage on the dolly. In addition, an inclined portion is interposed between the first and second rising portions. Therefore, when determining the positions of the first and second handle portions that are bridged across the pair of second rising portions, the positions of the handle portions can be selected from a relatively wide range in the front-rear direction of the platform. This allows, for example, the second handle portion to be positioned at a position that prevents the user's legs from interfering with the luggage when the user holds the second handle portion in his or her hand and transports the luggage on the cart.

[0011] In this way, when a user holds the second handle in his / her hands to transport luggage on the dolly, the user's arms can be prevented from interfering with the first handle, and further, the user's legs can be prevented from interfering with the luggage. Therefore, when carrying luggage on the dolly by holding the first handle or the second handle in his / her hands depending on the height difference of the users, the luggage can be carried on the dolly without imposing a burden on either user. This ensures the convenience of the dolly according to the height difference of the users.

[0012] (2) In the above aspect, a first bend between the first rising portion and the inclined portion may be located in a central portion of the vertical bar, and a second bend between the inclined portion and the second rising portion may be located at an upper portion of the vertical bar.

[0013] According to this configuration, the first bent portion between the first rising portion and the inclined portion is positioned in the center of the vertical bar. This allows the first rising portion to be relatively long. The first rising portion is raised vertically relative to the loading platform. This allows, for example, the first rising portion to support luggage placed on the loading platform, further increasing the convenience of the cart.

[0014] (3) In the above aspect, a first bend between the first rising portion and the inclined portion may be located at a lower portion of the vertical bar, and a second bend between the inclined portion and the second rising portion may be located at an upper portion of the vertical bar.

[0015] According to this configuration, the first bent portion between the first rising portion and the inclined portion is located at the bottom of the vertical bar. This allows the inclined portion to be relatively long. The inclined portion extends from the end of the first rising portion to the opposite side of the loading platform portion at an upward gradient. This allows, for example, a suitable distance to be provided between the luggage placed on the loading platform portion and the inclined portion. This makes it easier to load luggage onto the loading platform portion or to unload luggage from the loading platform portion, further increasing the convenience of the trolley.

[0016] (4) In the above aspect, the bending angle of the first bent portion and the bending angle of the second bent portion may be set to be the same obtuse angle.

[0017] According to this configuration, the bending angle of the first bent portion and the bending angle of the second bent portion are set to the same obtuse angle. Therefore, when a user holds the first handle portion or the second handle portion by hand and transports a load on the dolly, the pushing force applied from the user's hand to the first handle portion or the second handle portion can be efficiently transmitted to the first rising portion via the inclined portion. This allows the user's pushing force to be efficiently transmitted to the platform portion via the first rising portion. Therefore, the load can be transported well on the dolly, and the convenience of the dolly can be further improved.

[0018] (5) In the above aspect, the bending angle of the first bent portion and the bending angle of the second bent portion may be set to 136°.

[0019] According to this configuration, when the first bent portion is located at the center of the vertical bar to ensure a relatively long first rising portion, the bending angle of both the first bent portion and the bending angle of the second bent portion are set to 136°. Therefore, the first handle portion and the second handle portion can be positioned at a convenient position in the front-rear and up-down directions. This makes it possible to further improve the convenience of the dolly in accordance with the height difference of users.

[0020] (6) In the above aspect, the bending angle of the first bent portion and the bending angle of the second bent portion may be set to 169.63°.

[0021] According to this configuration, when the first bent portion is located at the bottom of the vertical bar to ensure a relatively long inclined portion, the bending angle of the first bent portion and the bending angle of the second bent portion are set to 169.63°. Therefore, the first handle portion and the second handle portion can be positioned in a convenient position in the front-rear and up-down directions. This ensures the convenience of the dolly according to the height difference of users.

[0022] (7) In the above aspect, both end portions of the second handle portion may be formed to be narrower in width than other portions of the second handle portion in a direction intersecting the second handle portion and in a direction intersecting the second raised portion.

[0023] According to this configuration, the width of both ends of the second handle is narrowed. Therefore, the entire end faces of both ends can be suitably contacted with the second raised portion. This allows, for example, the entire end faces of both ends to be reliably connected to the second raised portion by welding. Therefore, the strength of the second handle can be increased. Effect of the Invention

[0024] According to the present invention, convenience can be ensured by adapting to differences in height of users when transporting on a cart. [Brief description of the drawings]

In the drawings, the front of the dolly 10 is indicated by an arrow FR, the left side of the dolly 10 is indicated by an arrow LH, and the top of the dolly 10 is indicated by an arrow UP.

[0028] <Cargo area> FIG. 3 is a plan view of the carriage of the first embodiment as viewed from above. 1 to 3, the loading platform 12 is formed in a generally rectangular shape extending long in the front-rear direction in a plan view seen from above. The loading platform 12 has a loading surface 21 forming the upper surface. The loading surface 21 is formed flat so that luggage can be stably loaded thereon. A front wheel unit 13 and a rear wheel unit 14 are attached to a lower portion 12a of the loading platform 12.

[0029] <Front wheel unit> As shown in Figures 2 and 3, the front wheel unit 13 is provided on the front portion 12b of the lower portion 12a of the loading platform portion 12. The front wheel unit 13 includes a pair of front support parts 25, 25 and a pair of front wheels 26, 26. The pair of front support parts 25, 25 are attached to the left and right sides of the front portion 12b so as to be rotatable in the horizontal direction. The front wheels 26 are each rotatably supported by the pair of front support parts 25, 25.

[0030] <Rear wheel unit> The rear wheel unit 14 is provided on the rear portion 12c of the lower portion 12a of the loading platform portion 12. The rear wheel unit 14 includes a pair of rear support portions 27, 27 and a pair of rear wheels 28, 28. The pair of rear support portions 27, 27 are fixed to the left and right sides of the rear portion 12c. The rear wheels 28 are rotatably supported by the pair of rear support portions 27, 27.

[0031] <Connection> As shown in Figures 1 and 2, a pair of connection parts 15, 16 are provided on the left and right sides of the loading surface 21 of the cargo bed portion 12. The pair of connection parts 15, 16 are formed symmetrically. Of the pair of connection parts 15, 16, the left connection part 15 is attached to the left side of the loading surface 21. The left connection part 15 protrudes upward from the loading surface 21. Of the pair of connection parts 15, 16, the right connection part 16 is attached to the right side of the loading surface 21. The right connection part 16 protrudes upward from the loading surface 21. A handle part 18 is connected to the pair of connection parts 15, 16.

[0032] <Handle section> The handle portion 18 is provided on both sides (left and right sides) of the loading surface 21 via a pair of connecting portions 15, 16 so as to be positionable in a use position P1 and a folding position P2. The use position P1 is a position where the handle portion 18 is raised upward from the loading surface 21 of the cargo bed portion 12. The folding position P2 is a position where the handle portion 18 is laid down along the loading surface 21. The handle portion 18 includes a pair of vertical bars 31, 32, a first handle portion 33, and a second handle portion 34. The pair of vertical bars 31, 32 are formed symmetrically from pipes. Of the pair of vertical bars 31, 32, the left vertical bar 31 has a first rising portion 41, an inclined portion 42, and a second rising portion 43.

[0033] The first rising portion 41 has a base end supported by the left connecting portion 15 by a support pin 47 so as to be rotatable at an upper use position P1 and a forward folding position P2. When the handle portion 18 is in the use position P1, the first rising portion 41 rises in a straight line upward from the left side portion (side portion) of the platform portion 12 via the left connecting portion 15. The inclined portion 42 is connected to the tip portion (end portion) of the first rising portion 41.

[0034] When the handle portion 18 is in the usage position P1, the inclined portion 42 extends in a straight line at an upward gradient from the tip of the first rising portion 41 toward the opposite side of the loading platform portion 12 (i.e., the rear of the loading platform portion 12). A first bent portion 44 is formed at the location where the first rising portion 41 and the inclined portion 42 intersect. When the handle portion 18 is in the usage position P1, the first bent portion 44 is located in the center of the left vertical bar 31 in the up-down direction.

[0035] A second rising portion 43 is connected to the tip (end) of the inclined portion 42. When the handle portion 18 is positioned at the usage position P1, the second rising portion 43 rises in a straight line upward from the tip of the inclined portion 42. A second bent portion 45 is formed at the location where the inclined portion 42 and the second rising portion 43 intersect. When the handle portion 18 is positioned at the usage position P1, the second bent portion 45 is located at the top of the left vertical bar 31 in the up-down direction.

[0036] The bending angle θ1 of the first bent portion 44 and the bending angle θ2 of the second bent portion 45 are set to be the same obtuse angle. Hereinafter, the bending angle θ1 of the first bent portion 44 may be referred to as the "first bending angle θ1," and the bending angle θ2 of the second bent portion 45 may be referred to as the "second bending angle θ2." Specifically, the first bending angle θ1 and the second bending angle θ2 are set to be 136°. In the embodiment, an example is described in which the first bending angle θ1 and the second bending angle θ2 are set to 136°. However, for example, the first bending angle θ1 and the second bending angle θ2 may be selected from an angle range including ±several degrees, such as ±1°, ±2°, etc., based on 136°.

[0037] Of the pair of vertical bars 31, 32, the right vertical bar 32 is formed symmetrically with respect to the left vertical bar 31. Therefore, the same reference numerals as the respective components of the right vertical bar 32 are used for the respective components of the left vertical bar 31, and detailed explanations are omitted. The base end of the first rising portion 41 of the right vertical bar 32 is supported by the right connecting portion 16 via a support pin 47 so as to be rotatable at an upper use position P1 and a front folding position P2. That is, the pair of vertical bars 31, 32 are provided on both sides of the loading platform portion 12 via a pair of connecting portions 15, 16 so as to be able to be positioned at the use position P1 and the folding position P2.

[0038] A first handle portion 33 and a second handle portion 34 are provided on the pair of vertical bars 31, 32. The first handle portion 33 and the second handle portion 34 are formed of pipes. Specifically, the first handle portion 33 is bridged across the upper ends of the pair of second rising portions 43, 43 in the left-right direction. When the second handle portion 34 is disposed below the first handle portion 33, it is bridged across the pair of second rising portions 43, 43 in the left-right direction.

[0039] The pair of vertical bars 31, 32, the first handle portion 33, and the second handle portion 34 are integrally formed. The pair of vertical bars 31, 32, the first handle portion 33, and the second handle portion 34 form a handle portion 18. The handle portion 18 is supported by each support pin 47 of the pair of connecting portions 15, 16 so as to be able to be positioned at a use position P1 and a folded position P2. The handle portion 18 is held at the use position P1 and the folded position P2 by operating an operation bar 48 provided on the pair of connecting portions 15, 16.

[0040] As described above, according to the dolly 10 of the first embodiment, the pair of vertical bars 31, 32 of the handle portion 18 are each provided with a first rising portion 41, an inclined portion 42, and a second rising portion 43. When the handle portion 18 is raised to the use position P1, the pair of first rising portions 41, 41 can be arranged vertically by raising them upward from both sides of the loading platform portion 12. In addition, the pair of inclined portions 42, 42 extend from the tip of each first rising portion 41 to the rear of the loading platform portion 12 at an upward gradient. Furthermore, the pair of second rising portions 43, 43 can be arranged vertically by raising them upward from the tip of each inclined portion 42. In addition, the first handle portion 33 is bridged across the pair of second upright portions 43, 43 that are erected vertically, and the second handle portion 34 is bridged below the first handle portion 33.

[0041] Therefore, the second handle portion 34 can be disposed at the same position as the first handle portion 33 in the front-rear direction of the loading platform portion 12. This makes it possible to prevent, for example, the user's arm from interfering with the first handle portion 33 when the user holds the second handle portion 34 in his / her hand and transports luggage on the dolly 10.

[0042] In addition, the inclined portions 42 are interposed between the pair of first rising portions 41, 41 and the pair of second rising portions 43, 43. Therefore, when determining the positions of the first handle portion 33 and the second handle portion 34 bridged across the pair of second rising portions 43, 43, the positions of the handle portions 33, 34 can be selected from a relatively wide range in the front-rear direction of the loading platform portion 12. As a result, when a user holds the second handle portion 34 in his / her hand and transports luggage on a dolly, for example, the second handle portion 34 can be positioned at a position that prevents the user's legs from interfering with the luggage.

[0043] In this way, when a user holds the second handle 34 in his / her hand to transport luggage on the dolly 10, the user's arms can be prevented from interfering with the first handle 33, and further, the user's legs can be prevented from interfering with the luggage. Therefore, when carrying luggage on the dolly 10 by holding the first handle 33 or the second handle 34 in his / her hand depending on the height difference of the users, the luggage can be carried on the dolly 10 without imposing a burden on each user. This ensures the convenience of the dolly 10 according to the height difference of the users.

[0044] In addition, in the left vertical bar 31, the first bent portion 44 between the first rising portion 41 and the inclined portion 42 is positioned at the center of the left vertical bar 31. Similarly, in the right vertical bar 32, the first bent portion 44 between the first rising portion 41 and the inclined portion 42 is positioned at the center of the right vertical bar 32. This allows the pair of first rising portions 41, 41 to be relatively long. The pair of first rising portions 41, 41 are raised vertically to the loading platform 12 when the handle portion 18 is raised to the use position P1. This allows, for example, the pair of first rising portions 41, 41 to support luggage placed on the loading platform 12, further improving the convenience of the trolley 10.

[0045] Furthermore, the first bending angle θ1 of the pair of first bending portions 44,44 and the second bending angle θ2 of the pair of second bending portions 45,45 are set to the same obtuse angle. Therefore, when carrying luggage on a dolly by holding the first handle portion 33 or the second handle portion 34 by hand, the pushing force applied by hand to the first handle portion 33 or the second handle portion 34 can be efficiently transmitted to the pair of first rising portions 41,41 via the pair of inclined portions 42,42. This allows the pushing force of the user to be efficiently transmitted to the loading platform portion 12 via the pair of first rising portions 41, 41. Therefore, the baggage can be transported smoothly by the dolly 10, and the convenience of the dolly 10 can be further improved.

[0046] In addition, the pair of first bent portions 44, 44 are positioned in the center of the pair of vertical bars 31, 32, thereby ensuring a relatively long pair of first upright portions 41, 41. In this state, the first bending angle θ1 of each of the pair of first bent portions 44, 44 provided on the pair of vertical bars 31, 32 and the second bending angle θ2 of each of the pair of second bent portions 45, 45 are both set to 136°. Therefore, the first handle portion 33 and the second handle portion 34 can be positioned at a convenient position in the front-rear direction and the up-down direction. This allows the convenience of the dolly 10 to be further ensured in accordance with the height difference of users.

[0047] [Variations] Next, a modified example of the handle portion 18 provided on the dolly 10 of the first embodiment will be described with reference to Figs. Fig. 4 is a perspective view of a handle portion of a modified example seen from the left front side, and Fig. 5 is a cross-sectional view taken along line VV in Fig. 4. As shown in Figures 4 and 5, the modified handle portion 50 replaces the second handle portion 34 of the handle portion 18 of the first embodiment with a second handle portion 51, and the other configurations are generally similar to the handle portion 18 of the first embodiment.

[0048] The second handle portion 51 has a handle portion main body 52 (other portion of the second handle portion 51), a left end portion 53, and a right end portion 54. The handle portion main body 52 has a cross-sectional shape formed similar to that of the second handle portion 34 of the first embodiment. The left end portion 53 and the right end portion 54 are formed symmetrically. Therefore, the left end portion 53 will be described in detail, and a detailed description of the right end portion 54 will be omitted. Hereinafter, the left end portion 53 and the right end portion 54 may also be referred to as both ends 53, 54.

[0049] The left end 53 is formed to have a narrower width W than the handle body 52 in a direction intersecting the longitudinal direction of the second handle 51 and in a direction intersecting the longitudinal direction of the second rising portion 43. In the modified example, the "intersecting direction" will be described as the "orthogonal direction". Thus, the left end 53 is formed to have a narrower width W than the handle body 52 in the front-rear direction. Specifically, the left end 53 is flattened in the front-rear direction to have flat surfaces 53a in the front and rear. The width W of the left end 53 is formed narrower than the outer diameter (outer shape) of the second rising portion 43. The left end 53 also has a flat end surface 53b.

[0050] Here, for example, the portion of the second raised portion 43 facing the end surface 53b of the left end portion 53 is formed on the flat surface 43a. Therefore, when the end surface 53b of the left end portion 53 is formed flat, the entire end surface 53b can be suitably brought into contact with the flat surface 43a of the second raised portion 43. This allows, for example, the entire end surface 53b of the left end portion 53 to be reliably connected to the flat surface 43a of the second raised portion 43 by welding. Similarly, the entire end surface 54a of the right end portion 54 can be reliably connected to the flat surface 43a of the second raised portion 43 by welding. Therefore, the strength of the second handle portion 51 can be increased.

[0051] In the embodiment, an example in which the flat surface 43a is formed on the second rising portion 43 will be described, but the flat surface 43a does not necessarily have to be formed on the second rising portion 43. Even in this case, the entire end surface 53b of the left end portion 53 can be suitably brought into contact with the second rising portion 43 by forming the width W of the left end portion 53 to be narrow. This allows the entire end face 53b of the left end portion 53 to be reliably connected by welding to the second raised portion 43. Similarly, the entire end face 54a of the right end portion 54 can be reliably connected by welding to the second raised portion 43. This increases the strength of the second handle portion 51.

[0052] [Second embodiment] Next, a truck 100 according to a second embodiment will be described with reference to Figures 6 to 8. In the truck 100 according to the second embodiment, the same or similar members as those in the truck 10 according to the first embodiment are designated by the same reference numerals and detailed description thereof will be omitted. Fig. 6 is a perspective view of the bogie of the second embodiment as viewed from the front left, Fig. 7 is a side view of the bogie of the second embodiment as viewed from the left side, and Fig. 8 is a plan view of the bogie of the second embodiment as viewed from above.

[0053] <Trolley> 6 to 8, the dolly 100 includes a loading platform 102, a front wheel unit 13, a rear wheel unit 14, and a handle unit 104. The dolly 100 has a loading platform 102 that is smaller than that of the dolly 10 of the first embodiment, and further has a pair of first bent portions 124, 124 (described later) of the handle unit 104 formed downward, but the other configurations are generally similar to those of the dolly 10 of the first embodiment.

[0054] <Cargo area> The loading platform 102 is formed in a generally rectangular shape extending long in the front-rear direction in a plan view seen from above, as in the first embodiment. The loading platform 102 is formed such that, for example, the length dimension in the front-rear direction and the width dimension in the left-right direction of the loading platform 102 are smaller than those of the loading platform 12 of the first embodiment. The loading platform 102 has a loading surface 106 that forms the upper surface. The loading surface 106 is formed flat so that luggage can be stably placed thereon, similar to the loading surface 21 of the first embodiment. A front wheel unit 13 and a rear wheel unit 14 are attached to a lower portion 102a of the loading platform 102. A handle portion 104 is provided on both sides (left and right sides) of the rear portion 102b of the loading platform 102 so as to be positionable in a use position P3 and a folding position P4.

[0055] <Handle section> The handle portion 104 includes a pair of vertical bars 112, 113, a first handle portion 114, and a second handle portion 115. The pair of vertical bars 112, 113 are formed symmetrically from pipes. Of the pair of vertical bars 112, 113, the left vertical bar 112 has a first rising portion 121, an inclined portion 122, and a second rising portion 123. The first rising portion 121 has a base end supported by a support pin 127 on the left side of the loading platform 102 so as to be rotatable between an upper use position P3 and a front folding position P4. When the handle portion 104 is in the use position P3, the first rising portion 121 rises in a straight line upward from the left side (side portion) of the loading platform 102. An inclined portion 122 is connected to the tip (end) of the first rising portion 121.

[0056] When the handle portion 104 is disposed in the use position P3, the inclined portion 122 extends in a straight line at an upward gradient from the tip of the first rising portion 121 toward the opposite side of the loading platform portion 102 (i.e., the rear of the loading platform portion 102). A first bent portion 124 is formed at the location where the first rising portion 121 and the inclined portion 122 intersect. When the handle portion 104 is disposed in the use position P3, the first bent portion 124 is located at the bottom of the vertical bar 112 on the left side in the up-down direction.

[0057] A second rising portion 123 is connected to the tip (end) of the inclined portion 122. When the handle portion 104 is arranged in the usage position P3, the second rising portion 123 rises in a straight line upward from the tip of the inclined portion 122. A second bent portion 125 is formed at the location where the inclined portion 122 and the second rising portion 123 intersect. When the handle portion 104 is arranged in the usage position P3, the second bent portion 125 is located at the top of the vertical bar 112 on the left side in the up-down direction.

[0058] The bending angle θ3 of the first bent portion 124 and the bending angle θ4 of the second bent portion 125 are set to be the same obtuse angle. Hereinafter, the bending angle θ3 of the first bent portion 124 may be referred to as the "first bending angle θ3," and the bending angle θ4 of the second bent portion 125 may be referred to as the "second bending angle θ4." Specifically, the first bending angle θ3 and the second bending angle θ4 are set to be 169.63°. In the embodiment, an example is described in which the first bending angle θ3 and the second bending angle θ4 are set to 169.63°, but the first bending angle θ3 and the second bending angle θ4 may also be selected from an angle range including ±several degrees, such as ±1°, ±2°, etc., based on 169.63°.

[0059] Of the pair of vertical bars 112, 113, the right vertical bar 113 is formed symmetrically with respect to the left vertical bar 112. Therefore, the same reference numerals as the respective components of the right vertical bar 113 are used for the respective components of the left vertical bar 112, and detailed explanations are omitted. The base end of the first rising portion 121 of the right vertical bar 113 is supported by a support pin 127 on the right side of the loading platform 102 so as to be rotatable at an upper use position P3 and a front folding position P4. That is, the pair of vertical bars 112, 113 are provided on both sides of the loading platform 102 so as to be positionable at the use position P3 and the folding position P4.

[0060] A first handle portion 114 and a second handle portion 115 are provided on a pair of vertical bars 112, 113. The first handle portion 114 and the second handle portion 115 are formed of pipes. Specifically, the first handle portion 114 is bridged across the upper ends of the pair of second rising portions 123, 123 in the left-right direction. When the second handle portion 115 is disposed below the first handle portion 114, it is bridged across the pair of second rising portions 123, 123 in the left-right direction.

[0061] The pair of vertical bars 112, 113, the first handle portion 114, and the second handle portion 115 are integrally formed. The pair of vertical bars 112, 113, the first handle portion 114, and the second handle portion 115 form a handle portion 104. The handle portion 104 is supported by support pins 127 on both sides of the loading platform portion 102 so that it can be positioned at a use position P3 and a folding position P4. The handle portion 104 is held at the use position P3 and the folding position P4 by operating an operating portion 128 provided on the rear portion 102b of the loading platform portion 102.

[0062] As described above, according to the dolly 100 of the second embodiment, similarly to the dolly 10 of the first embodiment, the pair of second rising parts 123, 123 are arranged vertically by raising them upward from the tip end of each inclined part 122. In addition, the first handle part 114 is bridged across the pair of second rising parts 123, 123 raised vertically, and the second handle part 115 is bridged below the first handle part 114. Therefore, the second handle part 115 can be arranged at the same position as the first handle part 114 in the front-rear direction of the loading platform part 102. This makes it possible to suppress, for example, the user's arm from interfering with the first handle part 114 when the user holds the second handle part 115 by hand and transports luggage on the dolly 100.

[0063] Similarly to the dolly 10 of the first embodiment, the dolly 100 has an inclined portion 122 interposed between the pair of first rising portions 121, 121 and the pair of second rising portions 123, 123. Therefore, when determining the positions of the first handle portion 114 and the second handle portion 115 that are bridged across the pair of second rising portions 123, 123, the positions of the handle portions 114, 115 can be selected from a relatively wide range in the front-rear direction of the loading platform portion 102. As a result, when a user holds the second handle portion 115 by hand and transports luggage on the dolly, for example, the second handle portion 115 can be positioned at a position that prevents the user's legs from interfering with the luggage.

[0064] In this way, when a user carries luggage on the dolly 100 while holding the second handle 115 in his / her hand, the user's arm can be prevented from interfering with the first handle 114, and further, the user's legs can be prevented from interfering with the luggage. Therefore, when carrying luggage on the dolly 100 while holding the first handle 114 or the second handle 115 in his / her hand depending on the height difference of the users, the luggage can be carried on the dolly 100 without imposing a burden on each user. This ensures the convenience of the dolly 100 according to the height difference of the users.

[0065] In addition, in the left vertical bar 112, the first bent portion 124 between the first rising portion 121 and the inclined portion 122 is positioned at the bottom of the left vertical bar 112. Similarly, in the right vertical bar 113, the first bent portion 124 between the first rising portion 121 and the inclined portion 122 is positioned at the bottom of the right vertical bar 113. This ensures that the pair of inclined portions 122, 122 are relatively long. The pair of inclined portions 122, 122 extend from the tip of each first rising portion 121 to the opposite side of the loading platform portion 102 at an upward gradient. This allows, for example, a suitable distance to be created between the luggage placed on the loading platform 102 and the pair of inclined portions 122, 122. This makes it easier to load luggage onto the loading platform 102 or to unload luggage from the loading platform 102, further improving the convenience of the trolley 100.

[0066] Furthermore, the first bending angle θ3 of the pair of first bending portions 124,124 and the second bending angle θ4 of the pair of second bending portions 125,125 are set to the same obtuse angle. Therefore, when carrying luggage on a dolly by holding the first handle portion 114 or the second handle portion 115 by hand, the pushing force applied from the hand to the first handle portion 114 or the second handle portion 115 can be efficiently transmitted to the pair of first rising portions 121,121 via the pair of inclined portions 122,122. This allows the pushing force of the user to be efficiently transmitted to the loading platform portion 102 via the pair of first rising portions 121, 121. Therefore, the baggage can be transported smoothly by the dolly 100, and the convenience of the dolly 100 can be further improved.

[0067] In addition, the pair of first bent portions 124, 124 are positioned below the pair of vertical bars 112, 113, thereby ensuring a relatively long pair of inclined portions 122, 122. In this state, the first bending angle θ3 of each of the pair of first bent portions 124, 124 provided on the pair of vertical bars 112, 113 and the second bending angle θ4 of each of the pair of second bent portions 125, 125 are both set to 169.63°. Therefore, the first handle portion 114 and the second handle portion 115 can be disposed at positions that are convenient for use in the front-rear direction and the up-down direction. This ensures the convenience of the dolly 100 in accordance with the height difference of users.

[0068] [Variations] The second handle portion 115 provided on the handle portion 104 of the second embodiment can be formed in the same manner as the modified example of the first embodiment. That is, the width of both ends of the second handle portion 115 can be narrowed. This allows both ends of the second handle portion 115 to be reliably connected to the second raised portion 123 by welding, as in the modified example of the first embodiment, and the strength of the second handle portion 51 can be increased.

[0069] 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.

[0070] In addition, within the scope of the invention, the components in the above-described embodiments may be replaced with well-known components, and the above-described modified examples may be combined as appropriate. [Explanation of symbols]
