Description

The claimed invention relates to an article storage box for accommodating an article for the purpose of transportation, storage, or the like, such as a container.

A container, as is well known, is a rectangular parallelepiped box that holds goods for transportation and storage. In order to put in and take out an article, an opening is generally provided at an end in the length direction thereof, and an opening / closing door is provided there.

Since the width of the opening provided at the end in the length direction of the container is limited, a large opening may be provided at the side of the container so that even large articles can be efficiently carried in and out. be. Also in the example described in Patent Document 1 below, as shown in FIG. 12, an opening over almost the entire length of the container is provided on the side portion, and the opening is opened and closed by an upwardly rotatable side wall. That is, the side wall rotates upward together with a part of the upper surface wall to widen the side portion (opening) of the container, and conversely rotates downward to close the side portion.

Japanese Unexamined Patent Publication No. 2001-213497

Since the container described in Patent Document 1 can have a wide opening on the side, there is an advantage that a large article can be easily carried in and out through the opening. However, in order to rotate the side wall to open and close the opening, it is necessary to secure a space on the side of the container for the side wall to operate. If space is required on the side, the container cannot be placed next to the warehouse or factory, which is not preferable for smooth delivery of goods to and from the warehouse.

As a means of opening the side of the container widely, it is conceivable to provide a double door on the side, but even in that case, sufficient space is required on the side to open and close the door. There is also an option to open and close the side wall in a sliding door style, but in that case, in order to open almost the entire length of the side part, it is necessary to move the side wall of the sliding door type until it protrudes out of the container. Space must still be secured around it.
Although the container has been described as an example, the above is a problem that also applies to an article storage box other than the container.

The claimed invention has been made in consideration of the above points. That is, an article storage box having an opening on the side so that even a large article can be easily carried in and out, but it is not necessary to secure a space around the opening to open and close the opening is provided.

The article storage box of the present invention is an article storage box provided with an opening for loading and unloading articles on the side, and the opening is opened and closed by a sheet that is hung from above and pulled up, and the sheet is opened and closed. It is characterized in that the opening is tightly closed by.
In the above, the "side portion" refers to a portion (one or two locations) having the maximum length among the peripheral wall portions of the box placed on the ground or the floor surface. Further, "the opening is tightly closed" means that the inflow of air through the opening is in a state where there is no pressure difference between the inside and outside of the box or the pressure difference is small ( ^{does not exceed about 0.3 kg / cm 2).}・ It means that there is no outflow.
An example of the article storage box according to the present invention is shown in FIGS. 1 (a) and 1 (b). A side portion of the rectangular parallelepiped box 1 (that is, a peripheral wall portion having the maximum length) has an opening 2 extending over almost the entire length thereof, and the opening and closing 2 is opened and closed by a retractable seat 3.

Since the article storage box according to the invention is provided with an opening on the side thereof, the opening can be enlarged, and therefore even a large article can be easily carried in and out.
Further, since the opening is closed or opened by the hanging / pulling type sheet as described above, it is not necessary to secure almost a space around the box of the invention. The above-mentioned sheet that opens and closes the opening hangs down in the vertical direction and is pulled up, and it swivels and rotates away from the side, and moves beyond the end in the length direction of the box. Because it is not. Since it is not necessary to secure a space around the box, the box according to the invention can be used such that the box can be placed next to a warehouse or factory building and goods can be efficiently delivered to and from the box.
Not only is the opening covered by the sheet, but it can also be tightly closed as described above, preventing raindrops and dust from adhering to the items contained in the box and maintaining the soundness of the items contained. be able to. In addition, it is possible to control the atmosphere inside the box (temperature, humidity, internal gas components, etc.).

In the article storage box, the entire circumference or a part of the sheet surrounding the opening is pulled toward the outer periphery (direction from the vicinity of the center of the opening toward the outer edge) so that the opening is tightly closed. As a result, it is preferable that the article is pressed against the side surface of the close contact member which is continuously attached to the outer wall of the article storage box without a gap.
FIGS. 3 (a) and 3 (b) show a state in which a part of the sheet is pulled and pressed against the close contact member as described above. When the vicinity of the edge of the seat 3 (lower rod-shaped member 3X) is pulled toward the outer periphery (lower part in the drawing) by the stretching device 10 in the drawing, the inner side surface of the seat 3 is continuously attached to the outer wall of the box 1 without a gap. It is pressed against the side surface of the close contact member 14 to be brought into close contact with the side surface, thereby tightly closing a part of the entire circumference surrounding the opening 2.

If the sheet is pulled in this way and all or part of it is pressed against a continuous contact member, then only by the device for pulling the sheet and the contact member, the perimeter (or part thereof) of the opening. Is easily blocked. In other words, there is no need for special equipment / parts for blocking, and there is no need for time-consuming work.

In the article storage box, the entire circumference or a part of the sheet along the edge of the opening is placed on the outer wall of the article storage box outside the opening so that the opening is tightly closed. It is also preferable that the edge sheet is continuously attached without a gap and is joined by an airtight holding type fastener.
FIGS. 2 (a) and 2 (b) show a state in which a part of the sheet is joined to the edge sheet by a confidentiality type fastener. In the illustrated example, the side portions (left and right portions in FIG. 1) of the open / close portion (open / close sheet) 3a of the sheet 3 are between the edge sheet 3b and the edge sheet 3b which is tightly fixed to the box 1 by the fastening plate 3n. , It is joined by the confidentiality type fastener 20. When the opening / closing sheet 3a and the edge sheet 3b are joined by the fastener 20, the side portion of the opening 2 can be tightly closed by the airtightness holding function of the fastener 20 and the close contact effect of the fastening plate 3n. In the example of FIG. 2, the upper edge portion of the sheet 3 is tightly fixed to the box 1 by the fastening plate 3 m, and the lower portion of the sheet 3 is pulled by the tensioning device 10 of the above (FIG. 3) to be a close contact member. By being pressed against 14, each is tightly closed.

As described above, when the entire circumference or a part of the sheet along the edge of the opening is joined by the confidential fastener, the opening (or a part thereof) is tightly closed when the fastener is closed. And the opening will be opened when the fastener is opened. Since the operation of the fastener is easy, the work for opening and closing the opening is also easy.

In the article storage box, it is preferable that the inside is kept at a low humidity by a dehumidifier in a state where the opening is tightly closed.
FIG. 7B shows an example in which the dehumidifier 41 is installed in the box 1. The dehumidifier 41 keeps the internal space low humidity.
If the inside of the box is kept at a low humidity, there is an advantage that even an article that may be deteriorated due to the influence of humidity is kept in the box in a preferable state.

Further, in the above box, it is more preferable that a heat insulating material is attached to the inner wall in order to reduce the influence of the outside air temperature.
In the examples of FIGS. 7A and 7B, heat insulating materials 42a, 42b, and 42c are attached to the inner wall surfaces such as the ceiling, sides, and floor of the box 1.
If a heat insulating material is attached to the inner wall of the box, the change in the temperature inside the box is suppressed even if the outside air temperature changes. When the temperature inside the box drops, dew condensation may occur and water droplets may adhere to the surface of the contained item, but if the internal temperature change is suppressed by the heat insulating material, dew condensation will not occur and the contained item should be kept healthy. become.

In the article storage box, the upper edge of the sheet is continuously fixed to the outer wall of the article storage box at a portion above the opening without a gap, and the sheet is pulled up or hung down. It is preferable that the ropes are connected to a plurality of places of the sheet spaced apart in the horizontal direction (that is, the width direction of the opening).
In the box 1 illustrated in FIGS. 1 to 4, the upper edge portion of the sheet 3 is continuously and densely fixed to the outer wall by a fastening plate 3 m, and four ropes are attached to the sheet 3 for raising and lowering. 34 are connected.

In order to open and close the opening by raising and lowering (pulling and hanging) the sheet, it is conceivable to wind and rewind the sheet by placing a winder on the upper part of the opening. However, it is advantageous that the upper edge of the sheet is fixed to the outer wall of the box as described above in order to tightly close the opening. When winding and rewinding the sheet, it is not easy to close the opening tightly because the entire sheet moves up and down without fixing any part to the outer wall. In that respect, when the upper edge of the seat is fixed, the upper edge is always kept tightly closed with respect to the outer wall of the box, and each part of the hanging seat is attached to the outer wall. On the other hand, since it always comes to the same position, it is convenient for closing the entire circumference of the opening.
When the upper edge of the seat is fixed, a rope may be connected to a part of the seat in order to pull up or hang the seat. When the rope is pulled up, the seat is pulled up, and when the rope is lowered, the seat is hung down. When ropes are connected to a plurality of positions of the seat at intervals in the width direction, the seat is pulled up and hung so as not to tilt.

Regarding the above-mentioned article storage box, each of the above-mentioned ropes connected to a plurality of places of the above-mentioned seat is horizontally supported on the outer wall of the above-mentioned box and a drive source (output device including a motor or the like or a manual drive member). ) Is preferably wound around one rotating shaft.
In the box 1 illustrated in FIGS. 4 and 5, the seat pulling device 30 has the above configuration. That is, four ropes 34 are connected to raise and lower the seat 3 (FIG. 4), and they are wound around one horizontal rotating shaft 33 provided on the side opposite to the opening 2. (Fig. 5 (a)). The rotating shaft 33 is connected to a winch 31 which is a driving source via a driving rope 32 (FIG. 5B).

When raising and lowering the seat using a plurality of independent ropes, it is usually necessary to synchronize the speeds of the respective ropes. However, if a plurality of ropes connected to a plurality of places on the seat are wound around one common rotating shaft as described above and the rotating shaft is connected to a drive source, the speed of each of the plurality of ropes. Is naturally equal. That is, when the drive source rotates the rotating shaft, the plurality of ropes are wound and rewound on the rotating shaft and rise and fall at the same speed to smoothly raise and lower the seat. Since no control means for synchronization is required and one drive source is sufficient, the seat can be smoothly raised and lowered with a simple configuration.

In the above-mentioned article storage box, in order to open and close the above-mentioned opening by pulling up the above-mentioned sheet and the like, further
1) A lower rod-shaped member and a middle rod-shaped member extending to the left and right lengths of the sheet are attached to the lower part and the middle part of the sheet, respectively, and the rope is connected to the middle rod-shaped member.
2) When opening the opening, the middle rod-shaped member is pulled up to the upper surface (upper wall) of the box as long as the lower rod-shaped member does not exceed the upper edge of the side wall. It is preferable to have it.
Such a configuration is also adopted in the box 1 illustrated in FIGS. 4 to 6. That is, the lower rod-shaped member 3X and the middle rod-shaped member 3Y are attached to the lower portion and the middle portion of the seat 3, respectively, and the rope 34 for pulling up is connected to the middle rod-shaped member 3Y (FIGS. 4 and 5). (A)). Then, when the opening 2 is opened, the middle rod-shaped member 3Y is pulled up onto the upper surface of the box 1 within a range where the lower rod-shaped member 3X does not exceed the upper edge of the side wall (FIG. 6).

According to the above configuration, there are the following advantages.
First, if the rope for pulling up is connected to the central rod-shaped member as in 1) above, the seat can be pulled up smoothly. That is, when the vertical dimension of the opening provided on the side wall of the box is large, if the rope is connected to the lower part of the seat, there is a considerably vertically long seat above the connecting portion, so that the seat is pulled up. At that time, the sheet becomes wrinkled and it is difficult to raise it smoothly. However, when the rope is connected to the central rod-shaped member provided at the middle height portion, when the rope is pulled up, the seat rises smoothly without forming large wrinkles. Since the vertical dimension of the seat above the rope connection part is short, wrinkles that extend horizontally are unlikely to occur, and because the rope is connected to the seat via the central rod-shaped member instead of connecting directly to the seat, it is vertical. The reason is that the orientation wrinkles are less likely to occur.
Then, when opening the opening, if the lower rod-shaped member does not exceed the upper edge of the side wall as described in 2) above (see FIG. 6), the weight of the lower rod-shaped member always acts downward on the pulled up sheet. When the rope is loosened (rewound), the seat descends smoothly and hangs down to properly cover the opening.

In the box of the above invention, when the sheet is hung down and the opening is closed, a support rod is attached in the box so as to be in contact with the inner surface of the sheet, and the support rod is attached in the box so as to be in contact with the outer surface of the sheet. If a support rope is stretched on the outside of the box, it is advantageous when the box is transported by truck or the like.
9 (a) and 9 (b) exemplify a state in which the support rod 61 is mounted inside the box 1 and the support rope 65 is stretched outward.

As described above, when a support rod is mounted inside the box and the inner surface of the seat is brought into contact with it, and a support rope is stretched outside the box and brought into contact with the outer surface of the seat, the seat becomes its own. Displacement in the direction perpendicular to the surface is prevented. Therefore, the fluttering of the sheet can be suppressed even when the box is transported by a truck or the like or when the wind is strong. Therefore, there is an advantage that the sheet is not easily damaged as well as being quiet.

For the box of the above invention, it is preferable that a rail for suspending and moving the article for loading and unloading is attached to the upper part.
7 (a) and 7 (b) exemplify a box 1 in which an article moving machine 50 including such a rail 51 is attached to a ceiling portion.

If the moving rail is attached to the upper part of the box as described above, it becomes easy to carry in / out the article into the box. In particular, when a large opening is provided on the side and a large article is taken in and out through the opening, if the article can be moved while suspended using such a rail, the article can be carried in. The efficiency of unloading work is greatly improved.

As for the rails, in particular, a plurality of rails extend toward the back (the side away from the opening) with the upper part immediately inside the opening as the tip portion, and the direction of the tip portion of each rail is changed depending on the drive device. It is advantageous to provide a movable rail for connection that is connected to the tip portion and projects from the inside to the outside of the opening.
8 (a), (b), and (c) are detailed views showing the article moving machine 50 shown in FIG. 7 in an enlarged manner. Each of the plurality of rails 51 has a movable rail 52 at the tip. The movable rail 52 can be turned from the solid line state shown in the figure to the virtual line state by a driving device such as an electric telescopic cylinder 53 or a rod 54. The movable rail 52 in the state of the illustrated virtual line is connected to the tip end portion of the rail 51 and projects to the outside of the opening 2 of the box 1. In that state, the hanger 58 that suspends the article can continuously move along the rail 51 and the movable rail 52.

If the movable rail as described above is provided at the tip of the rail, the article may be moved extremely smoothly between the warehouse and the factory. That is, if the rail provided in the box and the rail in the warehouse or the like are connected via the above-mentioned movable rail, the suspended article is continuously connected between the box and the warehouse or the like along both rails. Can be transported.
Since the opening on the side of the article storage box according to the invention is opened and closed by a sheet, it can be laid horizontally at a position extremely close to a building such as a warehouse as described above. When the box is laid in such a position and the seat is pulled up to open the opening, if the above movable rail turns and protrudes from the inside to the outside of the opening, it is installed in a warehouse or the like. It is possible to connect the rail to the protruding end of the movable rail. If the rails are connected in this way, various articles can be hung and moved along the rails between the warehouse or the like and the box of the invention.

When a fastener is provided for the purpose of closing the opening as described above, a protective cover for the fastener is provided so as to cover the surface side of the fastener and share the tension acting from the sheet on the closed fastener. It is preferable that it is.
The protective cover 25 shown in FIG. 11 is such a cover.
If a protective cover is provided to cover the fastener and share the above-mentioned tension, the fastener can be protected from ultraviolet rays and the like and also from a mechanical load, and the durability of the fastener can be improved. ..

Since the article storage box of the present invention is provided with an opening on the side portion, the opening can be enlarged, and therefore a large article can be easily carried in and out. And since the opening is opened and closed by a hanging / pulling type seat, it is not necessary to secure a space around it for opening and closing. Since no space for opening and closing is required, the box of the present invention can be placed next to a warehouse or factory building, and goods can be efficiently delivered to and from those buildings.
Since the above-mentioned side opening can be tightly closed by the sheet, it is possible to prevent raindrops and dust from adhering to the articles contained in the box, and thus the soundness of the contained articles can be maintained. .. Since the inside of the box can be kept at a low humidity, it is possible to keep an article that tends to deteriorate due to an increase in humidity or dew condensation in a preferable state.
The above-mentioned opening and closing (hanging / pulling up) of the seat can be smoothly carried out by a device having a simple configuration. In addition, large articles can be carried in and out through the above openings efficiently and easily by appropriately providing rails on the upper part of the box.

It is a perspective view which shows the example which is the container described in Patent Document 1 and is provided with the opening in the side part.

The configuration of the article storage box 1 which is an embodiment of the invention is shown in FIGS. 1 to 9. The box 1 shown in the figure is a modified container for freight transportation, and is a container configured to be preferable for accommodating a large article (not shown). It is also configured to control the internal humidity and temperature.
The box 1 has a size of about 10 m in length, about 2.5 m in width, and about 3 m in height, but the side portion (that is, the length of the four peripheral walls) so that large articles can be efficiently carried in and out. A wall surface extending in the vertical direction. The front portion in FIG. 1 (a) and the left surface in FIG. 1 (b)) have a width of about 8.6 m and a height of about 2.5 m, which is close to the total length and height of the wall surface. An opening 2 having the size of is provided. The opening 2 is configured to be opened and closed by a sheet 3 that is hung from above and pulled up.

The sheet 3 is a polyester canvas that does not allow water to pass through and does not allow air to pass through, and has dimensions and an area that sufficiently covers the opening 2. It is possible to block.
i) First, the upper edge of the sheet 3 is fixed to the box 1 by the fastening plate 3 m as shown in FIGS. 2 and 3. The fastening plate 3m is a single plate (or a plurality of plates arranged continuously) extending over the entire length of the opening 2, and the upper edge of the sheet 3 is pressed by the fastening plate 3 m and the box is pressed with a bolt or the like. Fix it to the outer wall of 1. As a result, the upper edge portion of the sheet 3 is tightly closed, and air is prevented from entering and exiting from that portion.

ii) As shown in FIGS. 1 and 2, fasteners 20 extending vertically are attached to the left and right side edges of the seat 3, and the outermost portion is fixed to the box 1 by a fastening plate 3n. That is, first, the sheet 3 is divided into an opening / closing sheet 3a in the middle and a left and right edge sheet 3b by providing a cut 3c at the left and right edges of the sheet 3 leaving a part above. A fastener 20 is provided at the cut 3c, and element teeth 21 and 22 are attached to the opening / closing sheet 3a and the edge sheet 3b, respectively. The fastener 20 can engage the element teeth 21 and 22 by moving the slider 23 up and down, thereby opening and closing the cut 3c of the seat 3. The fastener 20 used is a simple waterproof type and can maintain a certain degree of airtightness. Sealing materials called tapes are attached to both edges of the sheet 3 that sandwiches the cut 3c, and when the element teeth 21 and 22 are engaged, the tapes come into close contact with each other to maintain airtightness between the inside and outside of the sheet 3. can. Further, a protective cover 24 for protecting the fastener 20 from ultraviolet rays and the like is provided on the outer surface of the fastener 20. The protective cover 24 is attached to the opening / closing sheet 3a and the edge sheet 3b, and is divided into left and right along the cut 3c of the sheet 3, and when the cut 3c is closed by the fastener 20, it thrusts as shown in the figure. Together, it covers the fastener 20.
As described above, the outermost portion of the sheet 3 outside the fastener 20 is fixed to the frame 1a of the box 1 by a vertically long fastening plate 3n and bolts or the like, and air is provided from there. I try not to go in and out. On the other hand, in the opening / closing sheet 3a, which is located inward of the cut 3c of the sheet 3, when the fastener 20 is released by pulling up the slider 23 to open the cut 3c, the portion other than the fixed upper edge is freely displaced. become able to. That is, the opening / closing sheet 3a in that state can be hung so as to cover the opening 2 or can be pulled up so as to open the opening 2.

iii) As shown in FIG. 3, the lower edge portion of the seat 3 is pulled downward by the tensioning device 10 to press the portion immediately above the seat 3 against the close contact member 14. As shown in FIGS. 1 and 3, the tensioning device 10 pulls the tensioning rope 12 extended in the length direction of the box 1 with a ratchet type winding machine 11, and the tensioning device 10 is formed at several points on the sheet 3. The hook 12a hung on the lower edge portion can be pulled downward by the action of the rope 12 and the plurality of pulleys 12c and the like. On the other hand, a holding portion 3c having a through hole is provided in the lower edge portion of the seat 3 to hold the lower rod-shaped member 3X, and the member 3X is vertically displaced in the recess of the guide frame 13 attached to the box 1. It is fitted as much as possible. When the above hooks 12a are hooked on the locking pieces 12b wound around several places of the member 3X, the lower edge portion of the seat 3 can be pulled downward when the tensioning device 10 is made to function.
As shown in FIGS. 3A and 3B, a close contact member 14 extending continuously in the length direction of the opening 2 is attached to the position along the lower edge of the opening 2 in the box 1 without a gap. The close contact member 14 is made of an elastic material such as rubber or PE (polyethylene) that does not damage the sheet 3. When the lower edge portion of the seat 3 is pulled downward by the tensioning device 10, the lower rod-shaped member 3X fits into the recess of the guide frame 13, and the inner surface of the seat 3 becomes the close contact member 14 at the portion immediately above the member X. It is pressed. As a result, the space between the lower edge of the sheet 3 and the lower edge of the opening 2 is tightly closed.

From the above points, when the sheet 3 (opening / closing sheet 3a) is hung down to cover the opening 2, the fasteners 20 on the left and right sides are closed, and the lower edge portion of the sheet 3 is pressed against the close contact member 14 by the tensioning device 10. The opening 2 and the entire peripheral edge thereof are tightly closed by the sheet 3 and each member in contact with the sheet 3. In the illustrated example, from the state of close contact between the sheet 3 and the fastener 20 and each peripheral edge, when the opening 2 is closed by the sheet 3, the internal airtight state is reached until the pressure difference from the outside becomes a maximum of 0.3 kg / cm2. Can be retained.

In the article storage box 1, a seat pulling device 30 is provided as shown in FIGS. 4 to 6 in order to raise and lower the seat 3 in front of the opening 2. Since the upper edge of the seat 3 is fixed to the box 1 and the entire seat 3 cannot be raised or lowered, the seat pulling device 30 uses a plurality of raising and lowering ropes 34 as shown in FIG. The part other than the upper edge will be pulled up or hung down.

The details of the seat pulling device 30 are as follows.
First, an electric winch 31, which is a drive source, is provided at the end of the box 1 as shown in FIGS. 4 and 5 (b), and at a portion separated from the article storage space. As shown in FIG. 5B, the driving rope 32 wound around the winch 31 is appropriately hung on the back side of the box 1 (the side opposite to the side provided with the opening 2) via a pulley, and the said It is wound around the drive take-up drum of the rotating shaft 33 attached to the back side.

Then, as shown in FIG. 5A, the elevating rope 34 is wound around the elevating winding drum on the rotating shaft 33 (at four locations on the rotating shaft 33 separately from the driving winding drum). .. The tips of the elevating ropes 34 are connected to the seat 3 (the central rod-shaped member 3Y described later). These ropes 34 are also hung from the rotating shaft 33 on the back side to the seat 3 on the front side by hanging them on the pulleys as appropriate.
The winding direction of the elevating rope 34 with respect to the rotating shaft 33 is opposite to that of the driving rope 32 as shown in FIGS. 5A and 5B. Therefore, when the drive rope 32 is wound by the winch 31 (see the arrow in FIG. 5B), the elevating rope 34 connected to the seat 3 is wound around the rotating shaft 33 and the seat 3 is pulled up (FIG. 5). (See the arrow in a). When the drive rope 32 is unwound from the winch 31, the elevating rope 34 can be unwound from the rotating shaft 33 and the seat 3 can be lowered.

As shown in FIG. 4, each of the elevating ropes 34 is connected to a central rod-shaped member 3Y horizontally attached to a middle portion (a substantially central portion in the vertical direction) of the seat 3 (opening / closing seat 3a). The reason why the seat 3 is connected to the middle rod-shaped member 3Y instead of the lower rod-shaped member 3X provided on the lower edge portion of the seat 3 is that the seat 3 can be pulled up smoothly.
That is, in this box 1, since the sheet 3 has a considerable dimension in the height direction in relation to the size of the opening 2, when the rope 34 is connected to the lower rod-shaped member 3X, the sheet 3 is pulled up. The long part (height about 2.5 m) above the connection part becomes wrinkled and it becomes difficult to rise smoothly. However, when the rope 34 is connected to the central rod-shaped member 3Y provided at the middle height portion of the seat 3, when the rope 34 is pulled up, the seat 3 smoothly rises without forming a large wrinkle and opens the opening 2. can do.

When the seat 3 is pulled up by the elevating rope 34 to open the opening 2, the pulling is stopped within a range in which the lower rod-shaped member 3X does not exceed the upper edge of the side wall of the box 1, as shown in FIG. That is, the seat 3 is not pulled up until the lower rod-shaped member 3X reaches the ceiling wall of the box 1. If the pulling of the seat is stopped within that range, the weight of the lower rod-shaped member 3X always acts downward on the pulled seat 3, so that the seat 3 smoothly descends and hangs down when the rope 34 is unwound from the rotating shaft 33. This is because it is possible to properly cover the opening 2.
In the illustrated example, when the seat 3 (opening / closing seat 3a) is pulled up beyond the above range, an unreasonable force acts on the upper end portion even when the fastener 20 is fully opened (the entire length is opened). .. Therefore, as shown in FIGS. 3 and 6, a stopper 3p for protecting the fastener 20 is attached to the upper part of the box 1. The stopper 3p is a circular pipe integrally attached to the lower part of the fastening plate 3m (see FIG. 3). In the state of FIG. 6 in which the seat 3 is pulled up to the maximum, the opening / closing seat 3a of the seat 3 is wrapped around the lower half of the stopper 3p, and it is difficult to raise the seat 3 any more.

As shown in FIGS. 7A and 7B, a humidity maintaining means 40 including a dehumidifier 41 and a heat insulating material 42 is provided inside the article storage box 1. As the heat insulating material 42, heat insulating materials 42a, 42b, 42c made of rock wool or the like are attached to each part of the ceiling wall, side wall, and floor by using rivets or the like.
The reason why the humidity maintaining means 40 is provided in this way is to keep the inside of the box 1 at a low humidity when the opening 2 is tightly closed by the sheet 3. The fact that the heat insulating material 42 is installed on the inner wall is also aimed at controlling the internal humidity without being affected by the outside air temperature. If the inside can be maintained at a low humidity, it becomes possible to keep an article whose surface or the like may be deteriorated due to an increase in humidity or dew condensation in a healthy state without deterioration.

As shown in FIGS. 7A and 7B, the article moving machine 50 including the rail 51 is arranged on the inner upper part of the box 1. As described above, the large opening 2 is provided in the side wall in order to facilitate loading and unloading of a large article in the box 1, but the illustrated article moving machine 50 also meets the purpose. ..
A plurality of rails 51 are provided in parallel on the ceiling wall of the box 1 and extend from the front position close to the opening 2 to the back position (closer to the back side) under the reinforcing member 1b (in the example of FIG. 7). 8) are installed. A plurality of hangers 58 having hooks for suspending articles and rollers for moving along the rails 51 are hung on each rail 51. When the article is suspended by using the hanger 58, it is easy to move the article in the length direction of the rail 51 (that is, between the vicinity of the opening 2 and the back).

A movable rail 52 is attached to each rail 51 of the article moving machine 50 as shown in FIGS. 8A, 8B, and 8C. The movable rail 52 can be connected to the tip of each rail 51 by appropriately changing its position and orientation as shown in the illustrated virtual line. In the box 1, since the opening 2 needs to be closed by the seat 3, the fixed rail 51 cannot be projected forward from the opening 2 (the elevating path of the seat 3), but the movable rail 52 is appropriately placed on the rail 1. When connected to, the rail 51 can be substantially extended forward of the opening 2. When the rail 51 is extended forward from the opening 2, when the box 1 is placed on a truck, for example, close to a warehouse or a factory and placed side by side, the rail 51 becomes a rail (not shown) in the warehouse or the like. By connecting, it becomes possible to move goods between the warehouse and the like and the box 1 extremely smoothly.

In order to connect the movable rails 52 to the ends of the rails 51, all the movable rails 52 are moved by a set of drive devices. That is, as shown in FIG. 8, the article moving machine 50 includes a drive device including an electric telescopic cylinder 53, a push-pull rod 54, a swing lever 55, and the like. The movable rail 52 is supported at the tip position of each rail 51 in a rotatable state by a support shaft 52a, and the upper portion of the movable rail 52 and the push-pull rod 54 are swiveled around the upper part of the rail 51 by a support shaft 55a. It is connected by a swing lever 55 that can be attached. When the cylinder 53 is contracted and the rod 54 is pulled back to the left in the drawing from the state shown in FIG. 8A, the swing lever 55 rotates counterclockwise to displace the movable rail 52 to the position of the virtual line shown in the drawing. When the movable rail 52 is displaced in this way and connected to the tip of the rail 51, the rail 51 and the movable rail are inserted by inserting a fixing support pin between the connecting holes 51b and 52b on the opposite side of the support shaft 52a. The connection with 52 can be ensured.

The article storage box 1 may be transported by truck or the like together with the articles housed inside. At that time, if the sheet 3 with the opening 2 closed flutters in the thickness direction, noise is generated and the sheet 3 is easily damaged. In consideration of this, the seat holding means 60 can be attached to the box 1 as shown in FIGS. 9A and 9B.
The seat holding means 60 includes a support rod 61 attached to the inside of the box 1 at a position inside the seat 3 and a support rope 65 stretched to the outside of the seat 3. The support rod 61 is a prism that can be erected and fixed between the ceiling wall and the floor of the box 1, and a turnbuckle 61a whose length can be adjusted is partially connected to the support rod 61. As shown in FIG. 8A, a plastic cushioning material 62 that does not easily damage the seat 3 is attached to the outward surface (the surface closer to the seat 3) of the support rod 61. By standing the support rod 61 at a position where it comes into contact with the inner surface of the seat 3, it is possible to prevent the seat 3 from being displaced inward during transportation or the like. Further, the support rod 61 can also play a role of preventing the ceiling portion (including the reinforcing member 1b) of the box 1 from bending due to the weight of the article.
The support rope 65 uses hooks 66 fixed to a plurality of locations on the outer wall surface of the box 1 and is tensioned as shown in the drawing so as to come into contact with the outer surface of the sheet 3 in which the opening 2 is closed. By erecting the support rod 61 and stretching the support rope 65, it is possible to prevent the sheet 3 from fluttering even during the transportation of the box 1.
The support rod 61 is preferably attached after the article has been housed in the box 1 and before the seat 3 is lowered into the opening 2. Further, the support rope 65 is preferably stretched by hanging it on the hook 66 after closing the opening 2 with the seat 3.

Although one embodiment has been shown above, the article storage box of the present invention may have a configuration other than the above, or may be used in other embodiments. for example,
a) In order to close the opening 2 tightly, it is not necessary to close all the upper edge, side edge and lower edge of the sheet as described above. Similar to the side edge portion in the above example, an airtight holding type fastener may be used for the lower edge portion or the like. Further, similarly to the case where the lower edge portion is closed in the above example, it is also possible to take a method of pulling the sheet outward from the outside of the opening and pressing it against the close contact member also at the side edge portion or the like.
b) The opening 2 is provided on one side of the box 1, but it is also possible to provide an opening on the opposite side or the like. In that case, since the number of openings increases, the performance of maintaining the confidentiality of the internal space tends to deteriorate, but it is advantageous in facilitating the loading and unloading of large articles.
c) Although an example of controlling the humidity in the box 1 with the opening 2 closed by the sheet 3 is shown, the box with the opening closed can be used for other purposes. It is also possible to fill the inside with a gas other than normal air to maintain the state, or to circulate the gas inside at a specific flow velocity for the purpose of exerting some influence on the contained articles and the like. ..

A protective cover 24 may be attached to the fastener 20 provided on the seat 3 of the article storage box 1 as shown in FIG. 2, but it is also preferable to attach the protective cover 25 according to FIGS. 10 and 11. The purpose of the protective cover 25 of FIGS. 10 and 11 is to protect the fastener 20 from ultraviolet rays and the like, whereas the protective cover 25 of FIGS. 10 and 11 can further protect the fastener 20 from a mechanical load. The details of the protective cover 25 are as follows.

Similar to the examples of FIGS. 1 and 2, the protective cover 25 is attached so as to cover the fasteners 20 on both the left and right sides of the seat 3 near both ends in the length direction of the box 1 as shown in FIG. As shown in FIGS. 11A and 11B, the protective cover 25 has one end 25a joined to the surface of the opening / closing sheet 3a located inside the fastener 20 of the sheet 3 and is on the opposite side. A plurality of engaging holes 25b are provided near the outer end portion. On the other hand, a plurality of protrusions 26 are attached on the fastening plate 3n as an object for fastening the engaging holes 25b. As described above, the fastening plate 3n is for fixing to the frame 1a of the box 1 and pressing and fixing the edge portion of the sheet 3. Further, each protrusion 26 is provided with a hole through which a rope 27, which will be described later, can be inserted.

When the opening / closing sheet 3a of the sheet 3 is lowered and the fastener 20 is closed, each of the engaging holes 25b is hooked to the protrusion 26 while slightly pulling the outer end of the protective cover 25 outward. Then, in order to prevent the engagement hole 25b from coming off from the protrusion 26, one rope (which may be a string or a wire) 27 is inserted into the hole of each protrusion 26, and the end portion thereof is a fixing member (which may be a string or a wire) on the box 1. For example, it is connected to the eyebolt 28) shown in FIG.
As described above, the protective cover 25 is covered on the surface side of the fastener 20 to cover the fastener 20, and when the tension acting on the sheet 3 increases, a part (or all) of the tension is applied to the protective cover 25. It can be burdened. That is, the protective cover 25 protects the fastener 20 from ultraviolet rays and the like, and also protects the fastener 20 from the tension (that is, mechanical load) acting in the direction of opening the closed fastener 20. Even if there is a problem that the fastener 20 is opened when the sheet 3 is lowered and the fastener 20 is closed, there is an advantage that the protective cover 25 can minimize the opening due to the fastener 20.
