Summary of the Invention

Problems to be Solved by the Invention

[0004] In the carrier shown in Patent Document 1, although the area for loading articles is increased by making the platform on which articles can be placed multi-stage, the area of the top surface is small, and it has been difficult to transport a large number of long articles or articles that cannot be stacked and placed.

[0005] In view of the above problems, an object of the present invention is to provide a carrier that can efficiently utilize the space of the carrier and can load and transport a plurality of articles of various shapes and properties.

Means for Solving the Problems

[0006] The present invention, which solves the above problem, comprises a frame body and wheels that support the frame body, and the frame body is provided with a loading section for placing items, the loading section including an upper loading section located above the wheels and a lower loading section located below the upper loading section, and the upper loading section is a carrier that is provided over the entire area surrounded by the frame body, thereby making it possible to provide a carrier that can load and transport items of various shapes. The lower loading section may be provided at a position lower than the height of the wheels. Furthermore, the cart may include a middle loading section provided between the upper loading section and the lower loading section, thereby expanding the area available for loading items. Furthermore, the frame may have a mounting rod spaced apart from the mounting portion, and the mounting rod may be provided on the same plane as the surface of the mounting portion. The support rods include inter-wheel support rods positioned between the wheels, thereby enabling the long member to be stably supported while efficiently utilizing the space within the frame body. In addition, the frame body has a contact portion that contacts the ground, and when the contact portion is in contact with the ground, the surface of the placement portion may be set horizontally to the ground, thereby maintaining horizontality even when not being transported and improving stable holding performance. The carrier may further include a gripping portion connected to the frame and gripped by a user, the gripping portion being flush with the top surface of the frame. The gripping portion may also be rotatable about the connection portion with the frame. The carrier may further include a plurality of gripping body parts extending perpendicularly from the end surface of the upper support portion, and a gripping support rod for connecting the plurality of gripping body parts. This facilitates the transportation of the carrier, allows it to be used as a shelf without taking up space when not in use, and also improves stable support performance by utilizing the gripping portion. In addition, the frame may have a protrusion that protrudes above the first placement portion, thereby making it possible to secure an article and make it easier to move the carrier even without the gripping portion.

[0009] Hereinafter, with reference to the drawings, a carrier X according to each embodiment of the present invention will be described. The description will detail the configuration of the embodiment, the method of implementation, and other examples in this order. Note that the embodiments shown below are examples of the present invention, and the present invention is not limited to the following embodiments. Also, the "approximate" in the application documents means that chamfering or rounding is performed on the subsequent shape, and that the elements constituting the shape are deformed or the length is changed within a range that does not impede the purpose of the configuration. When the user pushes the carrier X straight, the direction in which it moves is defined as the forward direction, and the opposite direction is defined as the backward direction. Also, when an article is placed on the placement portion 2 in the non-use state, the direction in which gravity acts is defined as the downward direction, and the opposite direction is defined as the upward direction. Further, the direction perpendicular to the surfaces in the front-rear and up-down directions is defined as the left-right direction.

[0010] 《First Embodiment》 As shown in FIGS. 1 to 4, the carrier X includes a frame body 1 and wheels 3 that support the frame body 1. The frame body 1 is provided with a placement portion 2 for placing an article. The placement portion 2 includes an upper placement portion 21 located above the wheels 3 and a lower placement portion 22 provided below the upper placement portion 21. The upper placement portion 21 is provided over the entire region surrounded by the frame body 1. Note that FIGS. 1(a) and 2(a) are perspective views of only the frame body 1 and the gripping portion 4, and FIGS. 1(b) and 2(b) are perspective views of the carrier X. FIGS. 3(a) and 3(b) are side views of the gripping portion 4 in the deployed state and the stored state, respectively, and FIGS. 4(a) to 4(d) are a plan view, a bottom view, a rear view, and a front view of the carrier X.

[0011] As shown in FIGS. 1 and 2, the frame body 1 is a structure formed by combining a plurality of rod-shaped members. As the rod-shaped members, metal pipe materials, square prism materials, L-shaped and T-shaped metal fittings, wood, etc. are assumed, and these may be provided in combination.

[0012] The frame body 1 includes a plurality of support frames 11 that support the placement portion 2, connecting rods 12 that connect the support frames 11 to each other, a placement rod 13 that is provided horizontally with respect to the surface of the support frame 11 and on which members can be placed, a wheel holding portion 14 that holds the wheels 3, a contact portion 15 that contacts the ground during use, and a protruding portion 16 that can be gripped by the user on the top surface of the frame body 1.

[0013] The placement part 2 is a part that cooperates with the support frame 11 to place articles, and has a placement surface 20 which is a plate-like member on which various articles can be placed on its upper surface, and this is attached to the upper surface of the support frame 11. As the placement part 2, various members such as metal materials, wood, plastics, and cloth materials are envisaged, but it is preferably water-resistant. Also, at least a part of the placement part 2 has water permeability, for example, the surface may be a mesh.

[0014] The placement part 2 includes an upper placement part 21 which is located above the wheels 3 and is provided over the entire area constituting the top surface of the frame body 1, a lower placement part 22 which is arranged laterally on the rear side of the wheels 3, and a middle placement part 23 which is arranged between the upper placement part 21 and the lower placement part 22. Also, on the lower surface of each placement part 2, a fixing assistance part R for assisting in fixing the articles on the upper surface of the placement part 2 is provided, and the articles are fixedly held via a rope R3.

[0015] The wheels 3 are ring-shaped members held by the wheel holding part 14, and are provided on the front side as a whole of the carrier X. A plurality (two in the embodiment) of wheels 3 having the same axis of rotation are provided at intervals on the carrier X, thereby enhancing the stability of the placement part 2. In the embodiment, the wheels 3 are pneumatic rubber tires, but they may also be plastic or wooden wheels.

[0016] The gripping part 4 is a part that the user grips when pushing the carrier X by hand, and has a rod-shaped gripping part main body 41 that projects rearward from the end of the frame body 1, a gripping placement rod 42 that bridges the plurality of gripping part main bodies 41, and a connecting part 43 that connects the gripping part main body 41 and the frame body 1. Here, the gripping part 4 is configured to be able to transition between a deployed state in which the gripping part main body 41 is horizontal with the ground and a stored state in which the gripping part main body 41 is perpendicular to the ground.

[0017] The support frame 11 is a frame portion including at least four rod-shaped structural members that are horizontally provided on the ground in the usage state, and the placement portion 2 is fixed on the surface formed on its inner circumference. In the embodiment, this structural member is a hollow square prism member, and the support frame 11 has an upper support frame 111 for fixing the upper placement portion 21, a lower support frame 113 for fixing the lower placement portion 22, and a middle support frame 114 for fixing the middle placement portion 23.

[0018] The upper support frame 111 is a substantially rectangular frame portion provided so as to cover the entire top surface of the frame body 1, and the edge is the outer edge on the upper end surface of the frame body 1. Here, the longitudinal structural members of the upper support frame 111 are parallel to the front-rear direction, and the lateral structural members are parallel to the left-right direction. Further, an upper frame auxiliary portion 112 that bridges the longitudinal structural members of the upper support frame 111 is installed in the left-right direction at approximately the center of the longitudinal structural members, thereby improving durability.

[0019] The lower support frame 113 is connected via a connecting rod 12 to the upper support frame 111 below the upper support frame 111, and is a substantially rectangular frame portion provided adjacent to the lateral side on the rearward side of the wheel 3. The lower support frame 113 is provided on substantially the same plane as the rotation axis of the wheel 3. The lower support frame 113 has the left-right direction as the longitudinal direction and the front-rear direction as the lateral direction. The length in the left-right direction is the same as the length in the left-right direction of the upper support frame 111, but the length in the front-rear direction is shorter than the length in the front-rear direction of the upper support frame 111.

[0020] Also, among the frames of the lower support frame 113, the structural member provided on the rearward side is a plate-shaped tread F that extends rearward. The user can apply the brake or temporarily lift the wheel 3 by stepping on the tread F. Further, the extending length of the tread F is at least longer than the diameter of the contact portion 15 so that the contact portion 15 can be fixed on the lower surface.

[0021] The middle support frame 114 is a substantially rectangular frame portion that is adjacent directly above the wheel 3 and is provided between the upper support frame 111 and the wheel 3, and is connected to the upper support frame 111 and the lower support frame 113 via the connecting rod 12. Also, the middle support frame 114 has its longitudinal direction in the left - right direction and its short - hand direction in the front - rear direction. The length in the left - right direction is the same as the length in the left - right direction of the upper support frame 111, but the length in the front - rear direction is shorter than the length in the front - rear direction of the upper support frame 111. Also, the length in the front - rear direction is longer than the diameter of the wheel 3, so that the middle placement portion 23 covers the wheel 3 in plan view. Preferably, the sizes and shapes of the lower support frame 113 and the middle support frame 114 are substantially the same, so that the same - shaped placement portions 2 can be placed to enhance compatibility. Also, the lower support frame 113 and the middle support frame 114 are arranged so as not to overlap in plan view, so that the middle placement portion 23 does not interfere when stacking articles on the lower placement portion 22.

[0022] Here, each support frame 11 is provided with a frame extension portion 11A for placing the placement portion 2 on the upper surface. In the embodiment, the frame extension portion 11A is arranged adjacent to a member provided in the front - rear direction of the support frame 11, and is a plate - like member fixed to the bottom surface of the support frame 11 by welding or the like. The frame extension portion 11A is provided away from the connection position of the two members so as not to interfere with the connection between the support frame 11 and the connecting rod 12. Also, the frame extension portion 11A is provided with holes corresponding to the holes provided in the placement portion 2 at a predetermined circumferential interval, and is fixed by sandwiching with bolts B1 and nuts B2 as shown in Fig. 5(a) at the position where these holes overlap. At this time, it is preferable that the head of the bolt B1 is embedded in the plane of the placement portion 2 to make the top surface of the placement portion 2 flat and improve the use performance. Note that the frame extension portion 11A may be provided as a part of the upper - frame auxiliary portion 112. In this case, the upper - frame auxiliary portion 112 is a plate - like material whose both ends are sandwiched and supported between the upper support frame 111 and the intermediate connecting rod 122 and bridges the intermediate connecting rods 122.

[0023] The connecting rod 12 is a rod provided to connect the support frames 11 to each other and fixedly hold the positional relationship and angle. The connecting rod 12 includes a rear connecting rod 121 provided at the rear of the frame body 1 to connect the upper-stage support frame 111 and the lower-stage support frame 113, an intermediate connecting rod 122 provided substantially in the middle in the front-rear direction of the frame body 1 adjacent to the upper-stage frame auxiliary part 112 to connect the upper-stage support frame 111, the lower-stage support frame 113, and the middle-stage support frame 114, a side connecting rod 123 provided at the left and right ends in the front of the frame body 1 to connect the upper-stage support frame 111, the lower-stage support frame 113, and the middle-stage support frame 114, and a front connecting rod 124 provided inside the side connecting rod 123 in the left-right direction in the front of the frame body 1.

[0024] Two rear connecting rods 121 are symmetrically provided at the left and right ends of the support frame 11. One end is connected to the rear-side corner of the upper-stage support frame 111, and the other end is connected to the rear-side corner of the lower-stage support frame 113. The rear connecting rod 121 is provided perpendicular to the support frame 11 and is located on the rear end face of the frame body 1 which is box-shaped as a whole.

[0025] Two intermediate connecting rods 122 are symmetrically provided at the left and right ends of the support frame 11. One end is connected to the vicinity of the upper-stage frame auxiliary part 112 on the longitudinal rod of the upper-stage support frame 111, and the other end is connected to the front-side corner of the lower-stage support frame 113. Also, the intermediate connecting rod 122 is connected to the rear-side corner of the middle-stage support frame 114 at its intermediate position. The intermediate connecting rod 122 is provided perpendicular to the support frame 11 and is located on the outer edge of the frame body 1. Thereby, the lower-stage support frame 113 and the middle-stage support frame 114 can be held at different heights.

[0026] Two side connecting rods 123 are symmetrically provided at the left and right ends of the support frame 11 in the left - right direction. One end is connected to the corner of the upper support frame 111 on the front - side, and the other end is connected to the corner of the lower support frame 113 on the front - side. Here, the side connecting rod 123 has a vertical portion which is a rod parallel to the vertical direction protruding downward from the corner of the upper support frame 111, a front - rear portion which is a rod parallel to the front - rear direction protruding forward from the corner of the lower support frame 113, and a connecting portion that smoothly connects the vertical portion and the front - rear portion, and is a bar material in a substantially L - shaped as a whole. Also, the vertical portion is connected to and supported by the front - side corner of the middle support frame 114 at its middle position. In addition, since the length of the front - rear portion is substantially the same as the length of the middle support frame 114 in the front - rear direction, and the length of the vertical portion is substantially the same as the length of the middle connecting rod 122, the frame body 1 becomes a box - type as a whole. Also, the distance from the front - rear portion to the middle support frame 114 is at least longer than the radius of the wheel 3 so that the middle mounting portion 23 does not interfere when the wheel 3 is provided.

[0027] Two front connecting rods 124 are symmetrically provided at positions away from the center of the support frame 11 in the left - right direction. One end is connected to the side of the front - side structural member of the upper support frame 111, and the other end is connected to the side of the front - side structural member of the lower support frame 113. The front connecting rod 124 is provided in substantially the same shape and size as the side connecting rod 123, has a vertical portion and a front - rear portion, and is provided parallel to the side connecting rod 123. Also, the front connecting rod 124 is connected to and supported by the front - side structural member of the middle support frame 114 in the middle of its vertical portion. In addition, the distance from the adjacent side connecting rod 123 to the front connecting rod 124 is provided to be at least larger than the width of the wheel 3 so that the wheel 3 can be sandwiched and installed between the two members.

[0028] The placement rod 13 is a rod provided at a position away from the support frame on the plane including the support frame 11, and is provided on the same plane as the placement part 2 installed on the support frame 11, so that a long article can be placed jointly. Preferably, the placement rod 13 is provided in parallel with a part of the structural members of the support frame 11 on the same plane, enhancing the placement performance. In the embodiment, the placement rod 13 includes an inter-wheel placement rod (first inter-wheel placement rod 131, second inter-wheel placement rod 132) provided on the same plane as the lower support frame 113, and a middle-stage placement rod 133 provided on the same plane as the middle-stage support frame 114. In addition, the gripping placement rod 42 described later is also provided on the same plane as the upper support frame 111 and acts as a part of the placement rod 13.

[0029] The first inter-wheel placement rod 131 and the second inter-wheel placement rod 132 are rods that bridge the front and rear parts of the two symmetrically provided side connection rods 123 and the front and rear parts of the front connection rod 124 respectively. The first inter-wheel placement rod 131 and the second inter-wheel placement rod 132 are provided separately from each other. The first inter-wheel placement rod 131 is provided on the rear side of the center of its front and rear parts, and the second inter-wheel placement rod 132 is provided on the front side of the center of its front and rear parts, maintaining the strength of the frame body 1. Since the upper ends of the two inter-wheel placement rods are provided on the same plane as the top surface of the lower support frame 113, the long article placed here is stably supported at a plurality of points on the first inter-wheel placement rod 131, the second inter-wheel placement rod 132, one side of the lower support frame 113 included in the lower placement part 22, and the plurality of points on the tread F, as shown in FIG. 6.

[0030] The middle-stage placement rod 133 is a rod that bridges the two symmetrically provided rear connection rods 121 at the intermediate position. Since the upper end of the middle-stage placement rod 133 is provided on the same plane as the top surface of the middle-stage support frame 114, the long article placed here is stably supported at a plurality of points on the two sides of the middle-stage support frame 114 and the middle-stage placement rod 133 included in the middle-stage placement part 23.

[0031] The wheel holding part 14 is a fitting for rotatably supporting the axis of the wheel 3, and is fixed on the same axis parallel to the left-right direction in the side connecting rod 123 and the front connecting rod 124. In the embodiment, the wheel holding part 14 is provided so as to protrude downward at each of the front and rear portions of the above member. Further, the wheel holding part 14 is provided between the first inter-wheel mounting rod 131 and the second inter-wheel mounting rod 132 at the front and rear portions of the side connecting rod 123, and is preferably located at approximately the center of the two members. Thereby, the rotation axis of the wheel 3 is less likely to be distorted, and the durability can be enhanced.

[0032] The contact part 15 applies a brake to the carrier X by friction when its end contacts the ground in a situation where the user is not gripping the gripping part 4. The contact part 15 is provided on the lower surface of the step F, and the height from the connection position with the step F to its lower end is substantially the same as the height from the connection position of the wheel holding part 14 to the lower end of the wheel 3. Therefore, in the carrier X, the surfaces of the support frame 11 to the placement part 2 are kept parallel to the ground. Further, the contact part 15 has a structure in which triangular frames including angles facing the ground are symmetrically provided on the left and right, and by reducing the contact area with the ground, the braking performance is enhanced, and further the strength is enhanced to reduce the occurrence of rattling.

[0033] The protruding part 16 is a U-shaped protruding portion provided upward on each of the sides parallel to the left-right direction of the upper support frame 111, and enables operations such as turning of the carrier X in a state where the gripping part 4 is stored. Further, the connection point between the end of the protruding part 16 and the upper support frame 111 is provided between the end and the center of the member connected in the upper support frame 111, and as shown in FIG. 6, an article can be put inside to contribute to stable support. Further, since the protruding part 16 protrudes more than the upper placement part 21, the rope R3 can also be tied, and the stability of the article can be further enhanced.

[0034] The upper placement part 21 is a part for placing an article together with the upper support frame 111 on the upper support frame 111. The upper placement part 21 is fixed to the inner peripheral surface of the upper support frame 111, has an upper placement surface 210 for placing an article on the top surface, and is provided so as to cover substantially the entire area surrounded by the frame body 1 in plan view, enabling large articles to be placed. The upper placement part 21 has holes for connecting to the frame extension part 11A near both end parts in the front-rear direction, and further has holes for connecting to the upper frame auxiliary part 112 (or the frame extension part 11A provided thereon) at a substantially central position in the front-rear direction. Also, the upper placement part 21 has holes for providing the fixing auxiliary part R between the holes of the frame extension part 11A and the upper frame auxiliary part 112 respectively. For this reason, it is fixed to the upper support frame 111 by at least three holes, and at least two fixing auxiliary parts R are provided. Since these are connected by bolts B1 and nuts B2 as shown in Fig. 7, the upper placement surface 210 and the fixing auxiliary part R can be removed from the frame body 1 according to the usage form preferred by the user. In particular, by removing the top surface, tall articles can be stably supported.

[0035] The lower placement part 22 is a part for placing an article together with the lower support frame 113 on the lower support frame 113. The lower placement part 22 is fixed to the inner peripheral surface of the lower support frame 113 and has a lower placement surface 220 for placing an article on the top surface. Also, the lower placement surface 220 has holes for connecting to the frame extension part 11A near both end parts in the front-rear direction, and further has holes for providing the fixing auxiliary part R at a substantially central position in the front-rear direction.

[0036] The middle placement part 23 is a part for placing an article together with the middle support frame 114 on the middle support frame 114. The lower placement part 22 is fixed to the inner peripheral surface of the middle support frame 114 and has a middle placement surface 230 for placing an article on the top surface. Its size, shape, and hole positions are substantially the same as those of the lower placement part 22.

[0037] Here, since the thickness of the placement portion 2 is smaller than the vertical height of the support frame 11, when the placement portion 2 is placed on the support frame 11, it is provided recessed with respect to the support frame 11. Thereby, even when the carrier X is tilted during use, the article is not caught on the corner of the support frame 11, so that the article can be easily held on the placement portion 2. On the other hand, the placement portion 2 may be placed and fixed on the top surface of the support frame 11. In this case, it becomes easy to slide and move the article.

[0038] Further, the area of the upper placement portion 21 is smaller than the areas of the lower placement portion 22 and the middle placement portion 23. Thereby, a plurality of placement portions 2 with different step heights are provided in the internal space of the frame body 1 so as not to overlap with the position of the wheels 3, and various articles can be supported.

[0039] The fixing auxiliary portion R has a fixing auxiliary tool main body R1 which is an L-shaped metal fitting as shown in FIG. 5(b), and a string fixing hole R2 for hanging a rope R3 on the fixing auxiliary tool main body R1. Although various string materials are assumed as the rope R3, it is preferably a member having elasticity. The fixing auxiliary tool main body R1 has a first plate in which two surfaces are vertically connected at the ends and which has a hole for connecting to the placement portion 2, and a second plate which protrudes downward from the first plate and includes the string fixing hole R2. Further, the end of the second plate is rounded to prevent interference and injury to the user.

[0040] As shown in FIG. 5(b), the string fixing hole R2 is provided near the end of the fixing auxiliary tool main body R1, and has a holding portion for actually hanging the rope R3 and a communicating portion that communicates from the holding portion toward the lower end of the second plate. The holding portion is provided above the communicating portion and is a long hole extending in the outer direction, and holds the rope R3 at the outer end in the outer direction.

[0041] As a modification example, the frame extension portion 11A and the upper frame auxiliary portion 112 may be made of a material having an L-shaped or T-shaped cross section in which the plate surface extends downward, and the string fixing hole R2 may be provided on this plate surface.

[0042] The grip part body 41 is a rod-shaped member provided symmetrically in the left-right direction, and is rotatably connected to the frame body 1 via the connection part 43 within a predetermined angular range, and is the part that the user grips during use. The grip part body 41 is at least shorter than the rear connecting rod 121 and is connected to the corner on the rearward side of the upper-stage placement part 21. The grip part body 41 is located on the same plane as the upper-stage placement part 21 in the deployed state and is located along the rear connecting rod 121 in the stored state, so that the handling performance during use is high and the storage performance is also high. Further, the grip part body 41 has a rod-shaped grip rod 411, a grip 412 that the user holds, a first protrusion 413 and a second protrusion 414 provided at a predetermined position in the radial direction of the grip rod 411.

[0043] The grip rod 411 is provided with a diameter smaller than the horizontal width of the connection part 43, and the end on the frame body side is covered by the connection part 43. The grip rod 411 is a cantilever beam with one end connected to the corner of the upper surface of the frame body 1 via the connection part 43, and a grip 412 with higher frictional force and elasticity than the grip rod 411 is provided to cover the periphery of the grip rod 411 at the other end.

[0044] The first protrusion 413 and the second protrusion 414 are connected to the first connection hole 432 and the second connection hole 433 described later. In the embodiment, these protrusions are formed by tightening a bolt B1 and a nut B2 from both ends into a hole penetrating in the diameter direction near the end of the grip rod 411. The first protrusion 413 is provided closer to the end of the grip rod 411 than the second protrusion 414.

[0045] The grip placement rod 42 is a member that bridges the left and right grip rods 411 and is provided at a position away from the connection part 43. The grip placement rod 42 is provided perpendicular to the protruding direction of the grip rod 411, and the upper end is provided on the same plane as the top surface of the upper-stage support frame 111 in the deployed state. Thereby, as shown in FIG. 6, a long article can be supported at two points of the upper-stage support frame 111 included in the upper-stage placement part 21 and at a plurality of points of the grip placement rod 42, so that stable support can be achieved. Further, the distance from the connection part 43 to the gripping and placing rod 42 is provided to be equal to the distance from the connection part 43 to the middle placing rod 133, and it becomes the same height as the middle placing rod 133 in the stored state. Thereby, in the stored state, a long article can be held by the middle placing rod 133 and the gripping and placing rod 42, enhancing convenience.

[0046] As shown in FIG. 1, the connection part 43 is an L-shaped metal fitting arranged such that the inner peripheral surface abuts at the rear end of the upper support frame 111 and the end of the rear connection rod 121, and rotates the gripping part main body 41 within a predetermined range. The connection part 43 includes a connection part main body 431 which is an L-shaped metal fitting, and a first connection hole 432 and a second connection hole 433 penetrating the surface of the connection part main body 431.

[0047] The first connection hole 432 and the second connection hole 433 are holes provided as shown in FIGS. 8(a) to 8(c), and slidably support the first protrusion 413 and the second protrusion 414. The first connection hole 432 is an elongated hole extending in the horizontal direction and is connected to the gripping part main body 41 via the first protrusion 413. The second connection hole 433 is integrally provided with an arc-shaped portion provided at a constant distance from the end of the frame body side of the first connection hole 432 and an elongated hole portion extending in a direction away from the frame body 1 from the upper end portion of the arc-shaped portion, and is connected to the gripping part main body 41 via the second protrusion 414. Here, the elongated hole portion is provided at the same height and the same length as the first connection hole 432, and supports the second protrusion 414 on its lower surface to horizontally hold the gripping part main body 41.

[0048] In this way, by providing the lower placement part 22 and the middle placement part 23 near the wheel 3, the vibration of the tire is less likely to be amplified, and the placed articles can be stably and easily supported. Also, since the connecting rod 12 is erected at the corner-contact part of the placement part 2, the holding performance of the articles can be further enhanced by tying a rope or a net covering the end face of the frame body 1 here. Further, it is preferable that the upper support frame 111 has the same height as the target vehicle for loading and unloading the articles. For example, the upper support frame 111 is provided at a position of 600 mm to 700 mm from the lower end of the contact part 15 in accordance with the height of the loading platform of a light truck. As a result, the articles can be loaded and unloaded only by sliding the articles, and the burden on the user can be reduced.

[0049] Hereinafter, the implementation method of the present invention will be described in detail. The present invention is implemented by a user who stacks and moves articles on the carrier X. Also, the implementation method shown below is an example, and the implementation method is not limited to this, and the order may be reversed.

[0050] First, the user stacks the articles on the placement part 2. In the case of a long article, as shown in FIG. 6, the article is horizontally supported by placing it between the protrusions 16 or between the front connecting rods 124. Here, since the carrier X includes the three support frames 11 and the placement rods 13, a large number of long articles can be supported at preferable positions.

[0051] Next, the user inserts the rope R3 into the string fixing hole R2 and hangs it on the holding part. This is done at the string fixing holes R2 at both ends, and the rope R3 is stretched in the left-right direction to fix the article as shown in FIG. 6.

[0052] Finally, the user holds the grip 412, applies a force forward while applying a slightly upward force, and moves the carrier X. As a result, a carrier X capable of loading and transporting a plurality of articles of various shapes can be provided. Also, the user can use the carrier X as it is like a shelf by rotating the gripping part 4 along the rear connecting rod 121.

[0057] The placement part 2 includes an upper-stage placement part 21. This upper-stage placement part 21 is connected to a material parallel to the front-rear direction of the upper-stage support frame 111 so as to be relatively rotatable via a rotating member T such as a hinge with the front-rear direction as the axis. Thereby, the upper-stage placement part 21 is provided so as to be transitionable from a placement state covering the upper surface of the frame body 1 shown in Fig. 10(a) to a holding state covering the side surface of the frame body 1 shown in Fig. 10(b). Thereby, in the placement state, the upper-stage placement part 21 can be used in the same manner as in the first embodiment, and in the holding state, articles can be held inside the frame body 1, and furthermore, those that are easy to roll and bulky and protrude above the top surface of the frame body 1 can be transported.

[0058] In the placement state, the upper-stage placement part 21 abuts against the top surface of the upper-stage support frame 111, and in the holding state, the upper-stage placement part 21 abuts against the connecting rod 12. Further, the upper-stage support frame 111 may be provided with a fitting for temporarily fixing the upper-stage placement part 21 in the placement state, and the connecting rod 12 may be provided with a fitting for temporarily fixing the upper-stage placement part 21 in the holding state.
