<Transport container A>
FIG. 1 is a side view showing a transport container A according to the present invention in an upright state St1. FIG. 2 is a front view of the transport container in the upright state St1. FIG. 3 is a side view of the transport container A in the forward tilted state St2. FIG. 4 is a schematic perspective view of the container 100. Note that FIG. 4 shows a schematic shape of the container 100, and illustrations of a lid portion 103, a pivot portion 108, etc., which will be described later, are omitted.

As shown in FIGS. 1 to 3, the transport container A includes a container 100 and a transport aid 200. The posture of the transport container A can be changed between an upright state St1 in which the container 100 is erected and the bottom surface 109 is in contact with the floor surface FL, and a forward tilted state St2 in which the container 100 is tilted toward the front surface 105 side. Note that the forward tilt angle of the forward tilted state St2 of the transport container A is an angle at which the transport container A does not return to the upright state St1 due to the weight of the transport container A containing the stored object Pr. In the transport container A, the container 100 is removably arranged on the transport aid 200.

In the upright state St1, the container 100 is supported by the transport aid 200. Further, in the forward tilted state St2, the conveyance aid 200 supports the container 100 so that the container 100 maintains the forward tilted state at a constant angle. The specific configurations of the container 100 and the transport aid 200 will be described below.

<Container 100>
The container 100 has a cylindrical shape with a bottom and has an upper opening 101 at the upper end. Further, the container 100 includes wheels 102, a lid portion 103, and a partition member 104.

The wheels 102 are disposed at the bottom of the container 100 so as to be biased toward the front side in the conveyance direction. The wheels 102 are rotatable around an axle that extends in the left-right direction. The container 100 can be tilted toward the front 105 side around the axle of the wheel 102 by pulling the upper part toward the front 105 while suppressing the rotation of the wheel 102, that is, the container 100 is tilted forward around the axle.

In the forward tilted state, the container 100 is supported by the wheels 102, and can be transported in the front and rear directions by rotation of the wheels 102. In addition, in this embodiment, the container 100, ie, the transport container A, will be described as being transported to the front surface 105 side.

The lid part 103 is arranged at the upper end of the container 100 so as to open and close the upper opening 101. The lid portion 103 includes a pivot rib 1031 that is fitted onto the pivot shaft portion 108 disposed at the upper end of the front surface 105 of the container 100 . The lid portion 103 is rotatable in the front-rear direction above the pivot shaft 108 around the pivot shaft 108 . The pivot shaft portion 108 is columnar and extends parallel to the axle of the wheel 102 . Note that the pivot shaft portion 108 may be the same member as the container 100, or may be a member formed of a different member from the container 100 and attached to the container 100.

The upper opening 101 of the lid portion 103 is opened by rotating forward. Conversely, the lid portion 103 is closed by rotating rearward about the pivot shaft portion 108.

As shown in FIG. 4, the container 100 includes an internal space S that can accommodate the contents Pr. The stored object Pr stored in the internal space S is, for example, a long-shaped stored object Pr formed by winding a sheet with a predetermined width. Inside the internal space S, a partition member 104 is provided which is disposed below the upper opening 101 in the upright state.

The partition member 104 divides the internal space S into front-rear and left-right directions perpendicular to the front-rear direction. When storing objects Pr in the internal space S, one object Pr is accommodated in each region partitioned by the partition member 104. In this way, by accommodating one object Pr in each area, contact between the objects Pr can be suppressed.

To explain further, the partition member 104 is arranged so as to be in contact with the stored object Pr above the longitudinal center and below the upper end thereof in the upright state. By arranging the partition member 104 in this manner, the upper part of the stored object Pr that contacts the partition member 104 is shorter than the lower part in both the upright state and the forward leaning state. As a result, in the standing state and the forward leaning state, unreasonable force is hardly applied to the part of the stored object Pr that comes into contact with the partition member 104, and it is possible to reduce the burden when storing and transporting the stored object Pr. . Note that if there is no problem even if the stored items Pr come into contact with each other, a plurality of stored items Pr may be stored in each area partitioned by the partition part 104.

The partition member 104 may have flexibility. Thereby, when the container 100 is tilted forward, the load on the stored object Pr can be suppressed by supporting the stored object Pr stored in the internal space S while being deformed. Furthermore, the partition member 104 may have an elastically deformable shape. By doing so, even if vibrations, shocks, etc. act on the contained object Pr accommodated in the internal space S of the container 100, deformation, damage, etc. of the contained object Pr can be suppressed.

<Transportation aid 200>
The transport aid 200 is attached to the container 100. The conveyance aid 200 supports the container 100 in a forward tilted state St2 tilted forward at a certain angle so as to be conveyable. That is, the conveyance aid 200 assists the conveyance of the container 100 by supporting the weight of the container 100 and the contents Pr contained in the container 100. Below, details of the conveyance aid 200 will be explained with reference to the drawings.

As shown in FIGS. 1, 2, etc., the conveyance aid 200 includes a main body 1, an auxiliary leg 2, a first wheel 31, a second wheel 32, and a leg opening limiter 4. Note that the conveyance aid 200 shown in this embodiment is formed by combining pipes. Rotating joints and fixed joints are used as joints between pipes.

A rotation joint includes a cylindrical part that is provided at an axial end of one pipe and into which a pipe to be joined is rotatably or rotatably inserted. A fixed joint secures the two pipes being joined together. Note that the joining of the pipes is not limited to this configuration, and a wide range of configurations that can be rotatably joined or fixed can be adopted.

In the following description, when each member is referred to as rotatably or pivotably joined or supported, a pivot joint is used. Moreover, when each member is said to be fixed, it is fixed by a fixed joint. In addition, there are some parts that are joined using a joining method other than this. Joints other than rotation joints and fixed joints will be explained as appropriate.

<Main body part 1>
The main body portion 1 includes a lower support portion 11 , a swing shaft portion 12 , a front support portion 13 , a holding shaft portion 14 , and a brace portion 15 . The lower support part 11 supports the lower part of the container 100. The lower support portion 11 includes two side support portions 111, two floor contact portions 112, a ring retaining portion 113, and a fixing column portion 114. The side support part 111, the floor contact part 112, the wheel stopper part 113, and the fixed column part 114 are each pipes.

The two floor contact parts 112 are respectively arranged outside the wheels 102 arranged on both the left and right sides of the container 100. The floor contact portion 112 is arranged to extend in the front-rear direction when the transport container A is in the upright state St1. The floor contact portion 112 contacts the floor surface FL over its entire length when the transport container A is in the upright state St1. The side support portion 111 is arranged above the floor contact portion 112 and parallel to the floor contact portion 112 .

The two side supports 111 are each arranged above each of the two floor contact parts 112 . Similarly to the floor contact portion 112, the side support portion 111 is also arranged to extend back and forth. That is, the side support portion 111 and the floor contact portion 112 are arranged substantially parallel to each other. The front end of the side support part 111 is fixed to a post part 131 of the front support part 13, which will be described later.

The side support part 111 and the floor contact part 112 are fixed by a fixing column part 114. The fixed column portion 114 connects the side support portion 111 and the front and rear ends of the floor contact portion 112, which are arranged substantially parallel to each other. Note that in this embodiment, one set of side support portions 111 and floor contact portions 112 are fixed by two fixing pillar portions 114, but the present invention is not limited to this. For example, it may be fixed using three or more fixing pillars 114. Note that it is possible to fix with one fixing column part 114, but in order to exhibit sufficient strength, it is possible to fix one set of side support part 111 and floor contact part 112 with a plurality of fixing columns 114. It is preferable to do so.

The wheel retaining portion 113 connects the floor contact portions 112 that are spaced apart from each other in the left and right directions. The wheel retaining portion 113 connects the front end portions of each floor contacting portion 112. When the transport container A is in the upright state St1, the ring retaining portion 113 also contacts the floor surface FL over its entire length. The rigidity of the lower support part 11 can be increased by fixing the two floor contact parts 112 with the wheel retaining part 113. The position of the wheel retaining part 113 in the front-rear direction may be aligned with the fixing column part 114 that fixes the front part of the side support part 111 and the floor contact part 112, or may be shifted.

The wheel clasp 113 contacts the wheel 102 of the container 100. To explain further, the wheel 102 and the wheel chocks 113 are in contact with each other with the axle of the wheel 102 positioned ahead of the wheel chocks 113. When the container 100 is attached to the conveyance aid 200, the wheels 102 come into contact with the wheel stopper 113, so that backward movement of the container 100 is restricted.

Note that the container 100 is placed on the transport aid 200 with the front surface 105 in contact with a front surface contact portion 132 of the front support portion 13, which will be described later. As a result, forward movement of the container 100 is restricted by the front contact portion 132, and movement of the wheel 102 is restricted by the wheel stopper portion 113, thereby restricting backward movement. That is, the container 100 is placed on the transport aid 200 with its forward and backward movement restricted. Further, in the transport container A of this embodiment, the wheels 102 are in contact with the floor surface FL in the upright state St1, but may be spaced apart from the floor surface FL.

In the upright state St1, when the container 100 is placed on the transport aid 200, the bottom surface 109 of the container 100 comes into contact with the floor surface FL. At this time, the side support portion 111 surrounds the side surface 107 of the container 100 above the bottom surface 109 . Thereby, the side support portion 111 serves as a regulating member that regulates movement when the container 100 moves in the left-right direction.

Although the lower support portion 11 of this embodiment includes the ring retaining portion 113 formed of one pipe, the present invention is not limited to this. For example, in order to further increase the rigidity of the lower support portion 11, the wheel retaining portion 113 may be configured with a plurality of pipes. At this time, the plurality of wheel retainers 113 may be configured to be arranged in close contact with each other, or may be formed so as to contact the front and rear of the lower portion of the wheel 102 to limit the movement of the wheel 102 back and forth. .

Further, a connecting member that is parallel to the wheel retaining portion 113 and connecting the two floor contact portions 112 may be arranged behind the wheel retaining portion 113. In this case, the bottom surface 109 of the container 100 may be placed on top of the connecting member. Furthermore, a connecting member connecting the two side support parts 111 may be provided at the rear end and/or front end at a position that does not interfere with the placement of the container 100. By connecting the side support portions 111 in this manner, it is possible to further increase the rigidity of the lower support portion 11.

The front end of the side support part 111 of the lower support part 11 in the transport direction is fixed to the front support part 13 . Here, the front support portion 13 will be explained. The front support section 13 is capable of supporting the front surface 105 of the container 100 placed on the transport aid 200 . The front support section 13 includes two support columns 131 , a front contact section 132 , and a grip shaft section 133 .

The two support columns 131 are arranged on the outside of the wheels 102 arranged on the left and right, and extend along the up-down direction. The side support portion 111 of the main body portion 1 is fixed to the support portion 131 . The first wheel 31 is attached to the lower end of the support column 131 . Details of the first wheel 31 will be described later.

The front contact portion 132 is arranged to connect the vertical intermediate portions of the two support columns 131. Front contact portion 132 contacts front surface 105 of container 100 . In addition, in the transport container A of this embodiment, the front surface contact portion 132 is in contact with the front surface 105 of the container 100 both in the upright state St1 and in the forward tilted state St2. Thereby, the transport aid 200 can stably hold the container 100.

However, it is not limited to this. For example, when the transport container A is in the upright state St1, the front contact portion 132 is separated from the front surface 105 of the container 100, and when the transport container A is in the forward tilted state St2, the front contact portion 132 is in contact with the front surface 105 of the container 100. good. That is, the front contact portion 132 may contact the front surface 105 of the container 100 when the transport container A is at least in the forward tilted state St2.

The upper ends of the two support columns 131 are arranged above the container 100. The grip shaft portion 133 connects the upper ends of the two support columns 131. The gripping shaft portion 133 can be used as a gripping portion to be gripped when transporting the transport container A in the forward tilted state St2. Furthermore, the swing shaft portion 12 is fixed to the grip shaft portion 133 .

As shown in FIG. 1 and the like, the gripping shaft portion 133 is arranged above the lid portion 103 of the container 100. As a result, even if the lid 103 of the container 100 placed on the transport aid 200 is unexpectedly opened, the lid 103 will be opened by contacting the gripping shaft 133, and the stored items Pr will pop out. can be suppressed. In addition, if the lid part 103 is configured to be difficult to open unexpectedly, the upper part of the support column 131 may be bent forward and the grip shaft part 133 may be attached at a position where it is unlikely to interfere with the lid part 103 during the opening/closing operation of the lid part 103. good. By doing so, the lid 103 can be opened and closed while the container 100 is tilted forward. Thereby, the height from the floor surface FL to the upper opening 101 becomes lower than in the upright state, making it easier to take out the stored items Pr.

The swing shaft portion 12 is disposed in front of the grip shaft portion 133 of the front support portion 13 and is fixed to the grip shaft portion 133. The swing shaft portion 12 extends parallel to the axle of the wheel 102. The swing shaft portion 12 is also formed of a pipe. The auxiliary leg portion 2 is swingably attached to the swing shaft portion 12 . Details of the auxiliary leg portion 2 will be described later.

The holding shaft portion 14 is fixed to the column portion 131 of the front support portion 13 . The holding shaft portion 14 extends parallel to the axle of the wheel 102. A first connecting rod portion 41 of the leg opening restriction portion 4, which will be described later, is rotatably attached to the holding shaft portion 14. Note that details of the leg opening restriction section 4 will be described later.

The brace portion 15 is formed of a pipe. The brace portion 15 has one end fixed to the side support portion 111 of the lower support portion 11 and the other end fixed to the column portion 131 of the front support portion 13. By providing the brace portion 15, the lower support portion 11 and the front support portion 13 can be firmly held. The brace portion 15 increases the rigidity of the conveyance aid 200. Therefore, by gripping the gripping shaft portion 133 of the front support portion 13 and tilting it forward, it is possible to tilt the transport container A forward into the forward tilted state St2. Note that if the main body portion 1 and the front support portion 13 are sufficiently firmly fixed, the brace portion 15 may be omitted. Conversely, a plurality of braces 15 may be provided to increase rigidity.

In addition, in this embodiment, although the main body part 1 is formed by combining a plurality of pipes, it is not limited to this. For example, a plate material, a bar material, etc. may be used.

<Auxiliary leg part 2>
The auxiliary legs 2 are formed of pipes and are attached to the swing shaft 12 in pairs on the left and right. The pair of auxiliary leg sections 2 are arranged on the outer side of the column section 131 of the front support section 13 in the left-right direction. The auxiliary leg portion 2 extends downward from the swing shaft portion 12. The auxiliary legs 2 can be swung between a closed state Sc (see FIGS. 1, 2, etc.) in which the lower end is close to the front surface 105 of the container 100 and an open state Sp (see FIG. 3) in which the lower end is farthest from the front surface 105. It is possible to move. In the present embodiment, the auxiliary leg portion 2 is formed of a pipe, but is not limited to this, as long as it is swingable with respect to the main body portion 1. For example, the auxiliary leg portion 2 may be a flat leg portion. Good too.

A second wheel 32 is attached to the tip of each of the pair of auxiliary legs 2. Note that details of the second wheel 32 will be described later.

When the transport container A is in the forward tilted state St2 (see FIG. 3), the auxiliary legs 2 are in the open state Sp. Furthermore, when the transport container A is in the upright state St1 (see FIG. 1), the auxiliary legs 2 are in the closed state Sc. At this time, the second wheel 32 separates from the floor surface FL.

<First wheel 31 and second wheel 32>
As described above, the first wheel 31 is attached to the lower end of the support column 131 of the front support section 13. Note that the first wheel 31 may be arranged so as to be able to roll in the front-rear direction, or may be arranged so as to be rotatable around the axis of the first wheel 31. The first wheels 31 are in contact with the floor surface FL both when the transport container A is in the upright state St1 and when it is in the forward tilted state St2. That is, when the state of the transport container A changes from the upright state St1 to the forward tilted state St2, the first wheels 31 are always in contact with the floor surface FL.

The second wheel 32 is attached to the lower end of each of the pair of auxiliary legs 2. That is, the second wheels 32 are provided on each auxiliary leg portion 2 and form a pair. When the transport container A is tilted forward in the forward tilted state St2, the second wheels 32 come into contact with the floor surface FL. The transport container A is supported on the floor surface FL by the first wheels 31 and the second wheels 32 in the forward tilted state St2. Then, the transport container A is transported by rotating the first wheel 31 and the second wheel 32.

During transportation, the second wheels 32 are movable around the axis of the auxiliary leg portion 2 . Therefore, when transporting the transport container A, the transport direction of the transport container A can be changed.

In this embodiment, the conveyance aid 200 includes two first wheels 31 and two second wheels 32, but is not limited thereto. For example, the number of the first wheel 31 or the second wheel 32 may be one, or three or more. In the forward leaning state St2, the number of the first wheels 31 and the second wheels 32 is not particularly limited as long as the first wheels 31 and the second wheels 32 can support the transport container A. When the total weight of the transport container A is heavy, such as when the weight of the contents Pr to be transported in the transport container A is large or the amount of transport is large, at least two first wheels are used to stably support the transport container A. 31 and two second wheels 32.

The leg opening limiter 4 limits the swinging of the auxiliary leg 2. The leg-spread limiter 4 is formed by combining pipes, but is not limited thereto. The leg opening restriction section 4 includes a first connecting rod section 41, a second connecting rod section 42, and a connecting shaft section 43.

The first connecting rod portion 41 is rotatably attached to the holding shaft portion 14 . The connecting shaft portion 43 is parallel to the axle of the wheel 102, and both ends thereof are fixed to each of the two auxiliary leg portions 2. That is, the connecting shaft portion 43 connects the two auxiliary leg portions 2 so that they can swing together.

One end of the second connecting rod portion 42 is rotatably attached to the connecting shaft portion 43. The first connecting rod part 41 and the second connecting rod part 42 are rotatably connected by a hinge part 40. The hinge portion 40 is folded by connecting the first connecting rod portion 41 and the second connecting rod portion 42 in a straight line and bending them upward. Further, the hinge portion 40 is configured to maintain a state in which the hinge portion 40 is connected in a straight line.

By changing the auxiliary leg portion 2 from the closed state Sc to the open state Sp, the folded first connecting rod portion 41 and the second connecting rod portion 42 are connected in a straight line. Then, by maintaining the hinge portion 40 in a state in which the first connecting rod portion 41 and the second connecting rod portion 42 are connected in a straight line, the auxiliary leg portion 2 is placed in an open state. Further, by folding the first connecting rod portion 41 and the second connecting rod portion 42 upward, the auxiliary leg portion 2 can be brought into the closed state Sc.

<Transportation using transport container A>
The configuration of the transport container A is as shown above. The transport container A can be brought into a forward tilted state St2 by tilting it forward with the auxiliary legs 2 in an open state Sp. The transport container A is supported on the floor surface FL by the first wheels 31 and the second wheels 32 by setting it in the forward tilted state St2. Then, the user can carry it by grasping the gripping shaft portion 133 and pulling it forward.

The transport container A is used, for example, to transport a certain number of long stored objects Pr. For example, a long container Pr formed through a predetermined process is stored in the internal space S. In the transport container A, the contents Pr are stored in the internal space S in the upright state St1. Then, when a predetermined state is reached (a state determined based on the number, weight, time, etc.), the transport container A is tilted forward and transported, for example, to the next process.

Further, after arriving at the destination, the container 100 is detached from the transport aid 200 by leaving the transport container A in the forward tilted state St2 and standing only the container 100 so that the bottom surface 109 contacts the floor surface FL. can be done. Thereby, the lid part 103 of the container 100 can be separated from the grip shaft part 133, and the lid part 103 can be opened and closed. In this state, the stored object Pr accommodated in the internal space S can be taken out.

As shown above, the transport container A stands on its own by being supported by the auxiliary legs 2 in the forward tilted state St2. Therefore, the user who transports the transport container A does not have to support the weight of the transport container A, and the force required for transport can be reduced. This reduces the burden on the user and further improves safety.

The transport container A has a small projected area in the vertical direction when in the upright state St1. Moreover, since the bottom surface 109 is in contact with the floor surface FL, it is stable. In other words, when the transport container A is in the upright state St1, it becomes stable and the area efficiency can be increased. Furthermore, since the direction of the container 100 in the upright state St1 coincides with the direction of gravity, when storing a long stored object Pr in the container 100, it is only necessary to support it in the vertical direction, and the stored object Pr can be, for example, , it is difficult for unreasonable forces such as bending stress to act on it. Therefore, it is possible to easily and safely store the long stored object Pr in the internal space S of the container 100.

Inside the container 100, a part of the contained object Pr is supported by the partition member 104. Therefore, since the stored item Pr is supported by the partition member 104 when the stored item Pr is taken out, bending stress and the like are reduced, and the burden on the stored item Pr can be reduced.

In other words, in the transport container A, by storing the stored items Pr in the upright state St1 and transporting them in the forward tilted state St2, the space can be used effectively, and the stored items Pr can be stored, taken out, and transported safely and easily. It is possible to do so.

Furthermore, in the transport container A of this embodiment, the container 100 and the transport aid 200 are separable. Therefore, it is possible to configure a structure in which the container 100 that needs to be transported is attached to the transport aid 200 and transported. Thereby, the container 100 and the contents Pr accommodated in the container 100 can be transported using fewer transport aids 200 than the containers 100.

<Modified example>
Another example of the transport container according to the present invention will be described with reference to the drawings. FIG. 5 is a side view of a modified example of the transport container A1 in the upright state St1. FIG. 6 is a side view of a modified example of the transport container A1 in the forward tilted state St2.

The transport container A1 shown in FIGS. 5 and 6 differs from the transport container A shown in FIG. Further, it differs from the transport container A in that the second wheels 32 are attached to the auxiliary leg section 2 via the second wheel support section 21. Therefore, parts of the transport container A1 that are substantially the same as those of the transport container A are given the same reference numerals as those of the transport container A, and detailed explanations of the same parts are omitted.

The swing shaft portion 12 is disposed in front of the front contact portion 132 of the front support portion 13 and is fixed to the front contact portion 132. The swing shaft portion 12 extends parallel to the axle of the wheel 102. The auxiliary leg portion 2 is swingably attached to the swing shaft portion 12.

A second wheel support portion 21 that rotatably supports a second wheel 32 is provided at the tip of each of the pair of auxiliary leg portions 2 . The second wheel support part 21 has a structure including a pipe, and the second wheel support part 21 is fixed to the auxiliary leg part 2.

When the transport container A1 is in the forward tilted state St2 (see FIG. 6), the auxiliary legs 2 are in the open state Sp. The second wheel support part 21 is fixed to the auxiliary leg part 2 so as to be perpendicular to the floor surface FL when the transport container A is in the forward tilted state St2 and the auxiliary leg part 2 is in the open state Sp. The second wheel support part 21 supports the second wheel 32 rotatably around an axis extending along the floor surface FL, and supports the second wheel 32 so that the direction of the second wheel 32 can be moved around an axis perpendicular to the floor surface FL. do.

The leg opening limiter 5 limits the swinging of the auxiliary leg 2. The leg opening limiter 5 is formed by combining pipes. The leg opening restriction section 5 includes two first connecting rod sections 51, two second connecting rod sections 52, a connecting shaft section 53, and an intermediate shaft section 54.

The two first connecting rod portions 51 are rotatably attached to the holding shaft portion 14 apart from each other in the left-right direction. Further, the intermediate shaft portion 54 is parallel to the axle of the wheel 102, and two first connecting rod portions 51 are fixed to both ends in the left and right direction.

The connecting shaft portion 53 is parallel to the axle of the wheel 102, and both ends thereof are fixed to each of the two auxiliary leg portions 2. That is, the connecting shaft portion 53 connects the two auxiliary leg portions 2 so that they can swing integrally.

The two second connecting rod parts 52 are arranged parallel to each other. One end of the two second connecting rod parts 52 is rotatably attached to the connecting shaft part 53. Further, the other ends of the two second connecting rod parts 52 are rotatably attached to the intermediate shaft part 54. That is, in the leg opening limiter 5, the first connecting rod portion 51 and the second connecting rod portion 52 are rotatable relative to each other around the intermediate shaft portion 54.

The leg opening limiter 5 constitutes a link mechanism that is linked to the movement of the auxiliary leg 2. That is, when the auxiliary leg portion 2 moves to the closed state Sc, the first connecting rod portion 51 rotates downward around the holding shaft portion 14. Further, the second connecting rod portion 52 rotates downward around the connecting shaft portion 53. Thereby, the leg-spread limiter 5 is folded by the intermediate shaft portion 54 being bent downward when the auxiliary leg portion 2 moves in the closing direction.

Similarly, when the auxiliary leg portion 2 moves to the open state Sp, the connecting shaft portion 53 fixed to the auxiliary leg portion 2 moves in a direction away from the holding shaft portion 14. As a result, the second connecting rod portion 52 rotatably attached to the connecting shaft portion 53 is pulled, and the first connecting rod portion 51 is also pulled via the intermediate shaft portion 54.

As a result, the first connecting rod portion 51 rotates around the holding shaft portion 14 . When viewed from the side, the first connecting rod portion 51 and the second connecting rod portion 52 are arranged on a straight line, so that the holding shaft portion 14 and the connecting shaft portion 53 in the leg opening restriction portion 5 are arranged in a straight line. The distance is the greatest. That is, when the first connecting rod part 51 and the second connecting rod part 52 of the leg-spread limiter 5 are arranged on a straight line, the auxiliary leg part 2 is located in the open state Sp.

<Tilt operation of transport container A1>
Next, the procedure for operating the transport container A1 will be explained with reference to the drawings. FIG. 7 is a side view of the transport container A1 when the intermediate shaft portion 44 of the leg-spread limiter 4 contacts the floor surface while the transport container A1 is tilted forward from the upright state St1 to the forward tilted state St2. FIG. 8 is a side view of the transport container A1 when the second wheels 32 contact the floor surface FL while the transport container A1 is tilted forward from the upright state St1 to the forward tilted state St2. Note that the tilting operation refers to an operation of moving the transport container A1 from the upright state St1 to the forward tilted state St2 or vice versa.

As shown in FIG. 5, when the transport container A1 is in the upright state St1, the floor contact part 112 of the lower support part 11 of the main body part 1 of the transport aid 200 is outside the side of the container 100, and the floor surface FL is in contact with. The wheel retaining portion 113 is also in contact with the floor surface FL. The bottom surface 109 of the container 100 is in contact with the floor surface FL. Thereby, in the upright state St1, the transport container A1 can stand by in a stable state.

When the transport container A1 is in the upright state St1, the auxiliary leg portion 2 is in the closed state Sc. The auxiliary leg portion 2 in the closed state Sc may be opened to the extent that it does not interfere with the surroundings by coming into contact with other members of the container 100 or the transport aid 200, or the like.

Furthermore, when the transport container A is in the upright state St1, the holding shaft portion 14 and the connecting shaft portion 53 are arranged in close positions. As a result, the first connecting rod portion 51 of the leg opening limiter 5 rotates downward around the holding shaft portion 14, and the second connecting rod portion 52 rotates downward around the connecting shaft portion 53. Thereby, the leg-spread limiter 5 is bent downward so that the intermediate shaft portion 54 becomes the lower end. At this time, the intermediate shaft portion 54 and the rotation joint attached to the tip of the second connecting rod portion 52 rotatably attached to the intermediate shaft portion 54 are separated from the floor surface FL.

The transport container A is transported in a forward tilted state St2 (see FIG. 6), which is tilted forward at a certain angle with respect to the floor surface FL. Next, a tilting operation in which the transport container A1 moves from the upright state St1 to the forward tilted state St2 will be described. First, with the first wheels 31 of the conveyance aid 200 fixed, the upper part of the front support part 13 is tilted forward. In other words, the transport container A1 tilts forward about the first wheels 31, that is, tilts forward.

As described above, the floor contacting part 112 of the lower support part 11 is arranged behind the wheels 102. Therefore, when the transport container A1 tilts forward about the axle of the wheel 102, the floor contact part 112 and the wheel stopper part 113 are separated from the floor surface FL.

When the transport container A1 is tilted forward, the wheels 102 and the bottom surface 109 of the container 100 are supported by the wheel stopper 113, and the front surface 105 is supported by the front surface contact portion 132. Thereby, the conveyance aid 200 supports the container 100.

As described above, the auxiliary leg portion 2 is swingably attached to the swing shaft portion 12. Therefore, when the transport container A is tilted forward, the auxiliary leg part 2 moves so as to hang substantially vertically downward from the swing shaft part 12 due to its own weight. That is, in the transport container A1 that tilts forward, the auxiliary leg portion 2 moves in a direction away from the front surface 105 of the container 100, centering on the swing shaft portion 12.

Then, as the auxiliary leg portion 2 moves in a direction away from the front surface 105 of the container 100, the first connecting rod portion 51 and the second connecting rod portion 52 are also pulled and opened. As a result, the intermediate shaft portion 54 also gradually moves upward. The speed at which the intermediate shaft portion 54 moves upward is slower than the speed at which the transport container A1 tilts. Therefore, for example, as shown in FIG. 7, when the transport container A1 is tilted to some extent, the intermediate shaft portion 54 contacts the floor surface FL before the second wheel 32 disposed at the tip of the auxiliary leg portion 2. .

It is possible to temporarily support the weight of the transport container A1 when the transport container A1 is tilted forward by the intermediate shaft portion 54 of the leg-spread limiter 5. Therefore, a sudden change in weight can be suppressed, and the burden on the user when tilting the transport container A1 forward is reduced.

By further tilting the transport container A1, the holding shaft portion 14 side of the first connecting rod portion 51 rotates downward about the intermediate shaft portion 54. Further, the second connecting rod portion 52 rotates downward on the connecting shaft portion 53 side around the intermediate shaft portion 54 . This operation of the first connecting rod section 51 and the second connecting rod section 52 causes the auxiliary leg section 2 to swing so as to approach the open state Sp. That is, by opening the first connecting rod part 51 and the second connecting rod part 52 around the intermediate shaft part 54, the auxiliary leg part 2 is moved forward from the position where it hangs approximately vertically downward from the swing shaft part 12. (See Figure 7).

By further tilting the transport container A1, the first connecting rod portion 51 and the second connecting rod portion 52 of the leg-spread limiter 5 are further opened. Then, the second wheel 32 attached to the second wheel support section 21 at the tip of the auxiliary leg section 2 comes into contact with the floor surface FL, and the intermediate shaft section 54 of the leg opening restriction section 5 separates from the floor surface FL. As described above, by moving the auxiliary leg section 2 in the opening direction by the leg opening restriction section 5, the position where the second wheel 32 first contacts the floor surface FL is on the front side of the swing shaft section 12. (See Figure 8).

When the transport container A1 is further tilted forward and the second wheels 32 receive force from the floor surface FL, the auxiliary legs 2 are urged in the opening direction. Then, the transport container A1 enters the forward tilted state St2, and the auxiliary legs 2 also enter the open state Sp (see FIG. 6).

When the transport container A1 is in the forward tilted state St2, the transport aid 200 supports the wheels 102 and the bottom surface 109 of the container 100 with the wheel stopper 113, and supports the front surface 105 of the container 100 with the front contact portion 132. As a result, the container 100 is supported by the transport aid 200, that is, the transport container A is in the forward tilted state St2.

Further, by fixing the first wheels 31 and lifting the gripping shaft 133 upward while the user grips the gripping shaft 133 of the transporting container A1 in the forward tilted state St2, the transporting container A1 can be placed in an upright position. Move to state St1. At this time, since the leg opening limiter 5 has a structure that folds downward, it is folded by its own weight. Accordingly, the auxiliary leg portion 2 also swings about the swing shaft portion 12 from the open state Sp toward the closed state Sc.

Then, as the second wheel 32 moves away from the floor FL, the intermediate shaft portion 54 of the leg opening limiter 5 comes into contact with the floor FL. Then, by further lifting the grip shaft part 133 from this state, the leg spread restriction part 5 is further lifted and the intermediate shaft part 54 is separated from the floor surface FL. When the floor contact part 112 and the wheel stopper part 113 of the lower support part 11 of the conveyance aid 200 come into contact with the floor surface FL, the leg opening restriction part 5 is completely folded and the auxiliary leg part 2 is in a closed state. It becomes Sc.

In this way, when the auxiliary leg section 2 moves from the open state to the closed state, the intermediate shaft section 54 comes into contact with the floor surface FL, thereby temporarily stopping the operation of the auxiliary leg section 2. Therefore, when the auxiliary leg portion 2 enters the closed state Sc, the force with which it contacts other parts of the container 100 and the conveyance aid 200 is limited. Further, by temporarily stopping the operation of the auxiliary leg portion 2, it is possible to urge the user to be careful about finger jamming, contact, etc.

As described above, by tilting the transport container A1 forward, the state changes from the upright state St1 to the forward tilted state St2. Moreover, by lifting it upward, the state changes from the forward leaning state St2 to the standing state St1. That is, the tilting motion can be performed with a simple motion, which is highly convenient for the user.

Further, when the transport container A1 is tilted forward, the auxiliary leg portion 2 is forcibly moved in the opening direction by the leg opening restriction portion 5. Therefore, it is possible to suppress the transport container A1 from falling forward due to the auxiliary leg section 2 not opening sufficiently. Thereby, it is possible to reduce the burden on the user when tilting the transport container A1 forward in preparation for transport, and to improve the safety of the user.

In addition, in the transport containers A and A1 of the present embodiment, the container 100 including the wheels 102 disposed at the bottom toward the front side in the transport direction is placed on the transport aid 200, but the structure is not limited to this. . It is also possible to place a container without wheels. In this case, the ring portion serves as a bottom support portion that supports the bottom surface of the container. Further, in the case of a configuration without wheels, the restriction of backward movement may be insufficient. In preparation for this case, a connecting member that connects the floor contacting parts may be provided on the rear side of the wheel retaining part in the conveyance direction. Furthermore, a connecting member may be provided at the rear of the side support portion 111.

Although the embodiments of the present invention have been described above, the present invention is not limited thereto. Further, the embodiments of the present invention can be modified in various ways without departing from the spirit of the invention.

The conveyance aid of the present invention can be employed, for example, as an aid for assisting the conveyance of a container that is long in the vertical direction and is equipped with wheels. Examples of such containers include trash cans, containers for transporting goods, and the like. The transport container of the present invention can also be configured as a wheelchair or a stroller by having a structure in which a person can sit on the container.
