Description

  The present invention relates to a container that can be used for loading and transporting articles and for storing the loaded articles as they are. The present invention relates to a container capable of easily taking out the loaded cargo.

  2. Description of the Related Art Conventionally, a container called a foldable roll box for loading articles is mainly known for transportation (for example, Patent Document 1 below). Such a roll box is configured so that a bottom surface and three side surfaces provided with casters can be folded, and articles are loaded and unloaded from the front side where the side surfaces are not provided. A reinforcing bar is stretched over the other side surface.

An example of the conventional roll box described above is shown in FIG. A roll box 101 shown in FIG. 4 is configured to be foldable by each member, that is, a bottom plate 102, a side plate 103 provided on the upper surface of the bottom plate 102, a side plate 104 facing the side plate 103, and a hinge 106. The back plate 105 connected to the face plate 103 and the side plate 104 is in an assembled state. In the roll box 101 in the assembled state, the reinforcing bar 107 is stretched over the side plate 103 and the side plate 104 on the front side (front side) when the article is not put in and out. . The reinforcing bar 107 has a fixed end 108 that is pivotally supported on the front side of the side plate 104 and a free end 109 that can move freely according to the rotation of the fixed end 108. When reinforcing, the free end 109 is stretched over the side surface 103 and fixed by the hook 110 as shown in FIG. Further, four casters 111 are attached to the lower surface of the bottom plate 102, and the roll box 101 can be easily moved by human power when transporting.

  As another example of the roll box, a type in which a bottom surface provided with casters and four side surfaces are configured to be foldable and one side surface is configured by a door member that can be opened and closed has been conventionally used. Known (for example, Patent Document 2 below). In such a roll box, the door member is opened to load and unload articles.

  The conventional roll box is formed in a folded structure from the viewpoint of securing a space when an article is not loaded and storing the roll box. After transporting to a place, it may be desired to store the goods loaded in a container. In this way, as a container intended to be used for both transportation and storage, apart from a roll box, a so-called pallet having a rectangular shape with an open top surface and a relatively shallow depth. The so-called container is widely used.

Japanese Patent Laid-Open No. 10-14743 Japanese Patent Laid-Open No. 2003-2326

  As described above, the conventional roll box is formed in a folding structure from the viewpoint of securing a space when an article is not loaded and storing the roll box, but the work of folding the roll box has considerable labor. At the same time, there is a possibility that an accident such as pinching a finger in the folding structure portion may occur, which is a problem. 4 is provided with a reinforcing bar 107 to reinforce the folding structure, the free end 109 of the reinforcing bar 107 is connected to the side plate. There is a possibility that an accident of pinching a finger between the hook 110 and the free end 109 may occur when the hook 103 is detached from the hook 103. Further, since the fixed end 108 is fixed to the side plate 104 in a rotatable state, the fixed end 108 is in a hanging state when the free end 109 is not stretched over the side plate 103 and may hit an operator during work. There is a possibility that an accident may occur in which a finger is caught in the shaft support portion of the fixed end 108.

  In addition, the conventional roll box has another problem due to the fact that one surface having no side surface or one surface to which a door member is attached is used as a front surface, and articles are loaded and unloaded from here. . That is, when a plurality of articles are loaded on the roll box, the articles are loaded in order from the front back direction, so that each time a load loaded in the front back direction is taken out of the loaded loads, The load in the front part of the front part had to be unloaded and then removed, which was a problem because it took a lot of labor and labor.

  On the other hand, a so-called pallet known in the art has an open top surface as described above, and can remove a loaded article from the top surface. There was no hassle of taking out the load. However, since the load is taken in and out from the upper surface, it has been necessary to form it at a shallow depth to the extent that the work for loading and unloading is not difficult. Therefore, using the pallet, it is possible to stack and stack the article higher than the height of the side surface of the pallet in order to mainly store the article. However, if the article is transported in this state, the load may be collapsed. Compared with the roll box, it was unsuitable for transportation.

  The present invention has been made in view of the above-mentioned problems, and is intended to provide a container that can be used for both transportation and storage, and is easy to take out a loaded load in consideration of safety in a work place. It is.

The feature of the present invention resides in that the bottom face and the frame body are fixed to form a rectangular parallelepiped frame, and at least two of the four side faces are openable.

That is, the present invention
(1) A bottom surface composed of a rectangular bottom plate, four side frames rising from the four corners of the bottom surface, and an upper surface frame connecting between adjacent end portions of the four side frames are fixed. A container formed, wherein at least two of the four side surfaces surrounded by the periphery of the bottom surface, the side surface frame, and the top surface frame are configured to be openable,
(2) Of the four side surfaces described above, one of the side surfaces is an opening surface formed by opening, and the side surface facing the opening surface is a door surface configured by an openable / closable door. The container according to (1) above, or (3) the container according to (1) or (2) above, wherein a conveying member is attached to the lower surface of the bottom surface,
Is a summary.

  In the present invention, the “container” means a box-shaped object for loading and transporting a load. In the present invention, the “lower surface of the bottom plate” means a surface of the bottom plate opposite to the surface on which articles are stacked.

  In addition, in the present invention, “openable” means not only a mode in which the door member is provided on the side surface and the door member can be both opened and closed, but is always open, that is, the side surface portion is opened. It is meant to include the case where it is formed.

  The present invention is a container that can transport an article without collapsing the load and can store the article while being loaded, and is a container called a so-called roll box and a conventional so-called pallet. It is a container that has both functions and is a container that ensures safety in work.

That is, since the present invention is composed of a rectangular frame having a bottom surface and a frame fixed, the folding operation of the container itself is eliminated, and there is no possibility of an accident during the folding operation.
Further, the present invention realizes a cuboid-shaped frame fixed as described above, and the upper part thereof is constituted by a frame fixed in a square shape, so that the overall strength is ensured by the frame. Yes. Therefore, even when any one or more of the four side surfaces of the rectangular parallelepiped are completely opened, the cross section and the upper part are U-shaped at the time of assembly as shown in FIG. Unlike the conventional folding roll box, there is no need to provide a reinforcing bar on the opening side surface. As a result, the occurrence of an accident due to the reinforcing bar being unmounted or removed, which has been a problem in the past, has been solved.

Moreover, the container of this invention has the effect that the loaded load is easy to take out. That is, since the container of the present invention is configured such that two or more of the four side surfaces can be opened, it is a load loaded from one of the side surfaces configured to be openable. When taking out the load loaded in the rear direction, the load can be easily taken out from the other side surface that can be opened. Therefore, it is not necessary to bother to lower the load loaded in the front direction in order to take the load loaded in the rear direction as in the prior art.
The structure which can open | release two or more side surfaces among the four side surfaces in the said invention is the structure implement | achieved because the framework in this invention came to exhibit sufficient intensity | strength fixed to a rectangular parallelepiped shape.

  Further, in the present invention in which the conveying member is attached to the lower surface of the bottom surface, it is preferable because the load can be easily moved and transported by human power.

The best mode for carrying out the present invention will be described below with reference to the drawings.

FIG. 1 is a container 1 showing an embodiment of the present invention. The container 1 has a rectangular parallelepiped shape in which a bottom surface 3 composed of a bottom plate 2, four side surface frames 4 rising from four corners of the bottom surface 3, and a top surface frame 5 connecting ends of the adjacent side surface frames 4 are fixed. Among the four side surfaces surrounded by the peripheral edge of the bottom plate 2, the side frame 4, and the upper surface frame 5, the side surface on the front side of the paper surface is an open surface that opens to the entire surface, and the side surface facing the open surface Reference numeral 8 denotes a door member 9, and a fixed side surface 6 and a side surface 7 exist between the opening surface and the side surface 8. The door member 9 is attached to and supported by one side frame 4 by a hinge 10, and a handle 11 is provided on the side opposite to the side on which the hinge 10 is attached.

  The side surface 6, the side surface 7, and the door member 9 constituting the side surface 8 are all configured by a lattice 12, and the inside can be observed from the outside of the container 1 through the gap of the lattice 12. In addition, casters 13 are provided at approximately four corners of the bottom surface 3 as conveying members, respectively.

  Below, the container 1 of this invention is demonstrated in detail.

(About a rectangular parallelepiped frame)
The bottom surface 3 in the container 1 of the present invention is composed of a bottom plate 2 that is a substantially flat plate member having a constant thickness. And the side surface frame 4 stands up from each of the approximately four corners of the bottom surface 3, and its end portion is connected to the top surface frame 5. The framework of the container 1 of the present invention having a rectangular parallelepiped shape is formed. In the present invention provided with the frame fixed in this way, the folding work performed in the conventional folding roll box is eliminated, so that an accident due to the folding work does not occur.

  The bottom surface in the present invention is not limited to the one composed only of the bottom plate as shown in FIG. For example, in another embodiment of the bottom surface, the bottom frame that borders the periphery of the bottom surface is formed in a square shape, and the side frames are provided upright from each of the four corners of the round shape bottom frame, A substantially flat bottom plate may be provided so as to fill the bottom frame (hereinafter also simply referred to as “bottom embodiment 1”). Alternatively, as another embodiment of the bottom surface, a substantially flat bottom plate is stacked and fixed on the upper surface of the above-mentioned B-shaped bottom frame, and side frames are formed upright from four corners of the bottom plate. (Hereinafter also simply referred to as “bottom embodiment 2”).

  As described above, the bottom surface according to the present invention includes at least a substantially planar bottom plate, and includes the one composed of only the bottom plate and the one composed of the bottom plate and the bottom frame. The thickness of the bottom plate can be appropriately designed so as to exhibit the strength required according to the weight of the article to be loaded and the purpose of use of the present invention. In general, it is desirable that the bottom plate is thicker in order to obtain a higher strength. However, in order to reduce the weight of the container itself or to reduce the manufacturing cost of the container, there is a demand for reducing the thickness of the bottom plate as much as possible. Therefore, the bottom surface in the present invention may be formed as in Embodiment 1 or Embodiment 2 of the bottom surface, and reinforcing ribs may be provided on the bottom surface of the bottom plate.

An embodiment of the present invention in which grid-like ribs are provided on the bottom surface of the bottom plate will be described with reference to FIG. The bottom surface 23 of the container 20 of the present invention shown in FIG. 3 includes a square-shaped bottom frame 26 and a bottom plate 22 stacked and fixed on the top surface of the bottom frame 26, and the bottom surface of the bottom plate 22. On the side, two ribs 21 are formed vertically and horizontally. Thus, by providing the reinforcing rib 21 on the lower surface of the substantially planar bottom plate 22, the strength of the bottom surface 23 can be improved, and therefore the thickness of the bottom plate 22 itself can be suppressed. According to the aspect of the present invention in which the rib 21 is provided, for example, even when the container 20 of the present invention is loaded with a load with a forklift or the like, it is possible to prevent the bottom surface from being damaged due to the weight of the load. can do.

  The material for forming the side frame and the top frame in the present invention, or the bottom frame provided as necessary, constitutes a conventional roll box or pallet such as a general-purpose metal, a resin showing a certain strength, or wood. What is used for the material to do can be selected suitably, and can be used. The same applies to the material constituting the side portion described later.

(About the top surface)
The upper surface portion of the container 1 of the present invention shown in FIG. 1 is constituted by a square-shaped upper surface frame 5, and the inside of the frame is formed to be open. In this way, by opening the upper surface portion, when loading an article exceeding the height of the container of the present invention, or when loading a plurality of loads, and a part of the load exceeds the height of the container, However, it has the merit that it can be loaded into the container through the upper surface. However, the upper surface portion of the container of the present invention is not limited to the above-described embodiment, and the strength of the present invention can be further increased by closing the inside of the upper surface frame 5 with a plate-shaped member or forming a lattice-shaped upper surface. May be improved. Particularly important in the upper surface portion of the present invention is that a B-shaped upper surface frame is fixed to a side frame connected to the upper surface frame, thereby forming a conventional roll-shaped roll having a U-shaped cross section. The aim is to achieve higher strength than pallets.

(About the side)
The side surface of the container 1 according to the present invention includes a side surface 6 and a side surface 7 whose surfaces are formed in a lattice shape, and a side surface 8 provided with a door member 9 on substantially the entire surface. It is the made opening surface. The opening surface is normally intended to be used for loading and unloading articles. That is, normally, the door member 9 on the side surface 8 is in a closed state, and articles can be sequentially loaded in the depth direction of the paper surface (that is, from the opening surface toward the side surface 8). Next, when removing the loaded article, if the article loaded on the front side of the paper (that is, the position close to the opening surface) is taken out, it can be easily removed from the opening surface, while being loaded in the depth direction on the paper surface. When the article is taken out, and particularly when the article stacked in the front direction of the paper becomes an obstacle and cannot be easily taken out from the opening surface, the door member 8 is opened as shown in FIG. It can be taken out. In addition, the above description demonstrated an example of use of the container 1 of this invention, Comprising: The usage method of this invention is not limited. Therefore, for example, it does not exclude loading an article from the side surface 8 and does not exclude taking out an article stacked in the depth direction of the paper surface from the opening surface.

  That is, the present invention is an article loaded from one openable side surface by forming at least two of the four side surfaces surrounded by the peripheral edge of the bottom surface, the side surface frame, and the top surface frame so as to be openable. When it is desired to take out an article stacked in the depth direction with respect to the side surface, the article can be easily taken out from another openable side surface. Therefore, of the side surfaces in the present invention, the side surfaces formed so as to be openable are not limited to the two side surfaces facing each other as shown in FIG. 1, and adjacent side surfaces may be formed so as to be openable, or Arbitrary three surfaces or even the entire surface may be formed to be openable. In addition, as an openable side surface, whether to form an opening surface or a side surface including a door member can be appropriately designed according to the article to be loaded, the use, the size of the container, or the like. However, the side surface formed as the opening surface is easy to load and take out the article, but the article loaded during transportation may fall, so from this point of view, only one surface is the opening surface. Preferably, the other openable surface is formed with a door member. In particular, as shown in FIG. 1, it is desirable that the opening surface is formed by opening substantially the entire surface of one side surface, and the side surface facing the opening surface is a door surface constituted by a door that can be opened and closed.

  The side surface 6, the side surface 7, and the side surface 8 shown in FIG. 1 are all formed in a lattice shape, but the side surface of the present invention is not limited to being formed in a lattice shape. When there is a situation such as loading a relatively small article, the side surface may be formed with a surface without a gap instead of a lattice shape. By forming the side surfaces in a lattice shape, it is possible to easily observe articles loaded in the container from the outside of the container and to improve the ventilation in the container.

  Further, the side surface formed by a door member that can be opened is not only a single door as in the door member 9 in the container 1 but also a double door or a shutter type door. Any door member may be adopted as long as it can be opened and closed and can open almost the entire side surface.

(About conveying members)
A caster 13 is provided as a conveying member on the lower surface of the bottom surface 3 of the container 1 shown in FIG. In the present invention, the attachment of the conveying member is not an essential configuration, but it is desirable that a caster, a sliding member, and the like are attached to the lower surface of the bottom surface from the viewpoint that the container can be easily conveyed by human power or the like. However, as a transport method, when it is planned to transport on a cart or to be lifted and moved by a forklift or the like without relying on human power, the transport member such as the caster is not necessarily provided.

(About dimensions of the present invention)
The container of the present invention is a container excellent in both transportation and storage, and can be applied to a wide range of fields of use because various articles can be transported and stored. Therefore, it is desirable to determine the dimensions of the container of the present invention according to the intended field of use. For example, when the main purpose is to load and transport a plurality of containers on a 4-ton truck, the cross-sectional dimensions are about 1 m x about 1 m from the viewpoint of aligning the containers without excess or deficiency on the 4-ton truck bed. It is desirable that the height be within the height of the loading platform of the 4-ton truck and that the operator does not hit his head against the top frame. It is preferably 9 m or more and about 2.5 m or less, and more preferably around 2 m.

It is a perspective view which shows the example of one Embodiment of the container of this invention. It is a perspective view of the state which opened the door member of the container shown in FIG. It is a perspective view which shows the example of other embodiment of the container of this invention, Comprising: The container was turned down and the perspective view which enabled visual observation of the bottom face part. It is a perspective view which shows the example of the conventional roll box.
