Description

Detailed Description of the Invention 【Technical field】

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproofing tool suitable for use as a carrier for cargo transportation. In particular, it is composed of a waterproof cover and a holder mounted on the top curtain of this waterproof cover, and the holder is curved to protect cargo in the carrier from rainwater and prevent rainwater from collecting on the top curtain. It is the one.

[Background technology]

[0002] Generally, when cargo (luggage) contained in cardboard or the like is unloaded from a warehouse and loaded on a cargo truck, or when cargo loaded on this cargo truck is unloaded and loaded into the warehouse. Cargo carriers known as logistics equipment (roll boxes, containers, etc.)
Is often used.

FIG. 16 shows an example of a carrier used for carrying such a cargo. The carrier 10 shown in FIG. 16 is a foldable carrier, and in this example, it has four metal frames 10A to 10D and a pedestal 12, and a carrier as shown in FIG. 16 by assembling these four members. It becomes 10. Reinforcing rods 15 are vertically and horizontally provided over the metal frames 10A to 10D, and serve as a protective fence for reinforcing the metal frame and preventing the cargo from coming off. A plurality of casters 14 are attached to the lower side of the base 12 to facilitate the movement of the carrier 10.

A large number of various cargoes 16 are loaded on the carrier 10, as shown in FIG. In order to load as many cargoes 16 as possible, the carrier 10 is often relatively large. For example, a rectangular shape having a height close to 170 to 180 cm is used. Each of the cargoes 16 has a sorting slip 18 indicating the destination of transportation, which is attached to the side surface or the flat surface of the cargo 16.

DISCLOSURE OF THE INVENTION [Problems to be Solved by the Invention]

By the way, the above-mentioned carrier 10 may be temporarily stored near the entrance of the warehouse, but when the warehouse is not large in scale, the warehouse is provided with a small eaves. There are many. Therefore, some carriers 10 are temporarily stored (leaved) under the blue ceiling.

In this way, when the carrier 10 is stored under the blue ceiling, when the rain pattern suddenly starts to rain, the worker can quickly put a vinyl sheet on the carrier 10 to load the carrier 10 from the rain. I try to prevent cargo.

However, even if a vinyl sheet is put on, it is often experienced that when the carrier 10 is large, it cannot be covered so easily. Further, in the case of a simple vinyl sheet, since it is a sheet, it is easily detached from the carrier 10 by the wind, and it is not a cover that copes with wind and rain.

Even if a dedicated cover is devised as a waterproofing tool, it is necessary to consider the weight and the usability (easiness of mounting) in order to create the dedicated cover. Furthermore, when the rain stops and the exclusive cover is removed from the carrier 10, the rainwater collected on the top of the exclusive cover must be dropped to the ground before the cargo 16 is splashed with the rainwater when it is removed.
Rainwater may enter the cargo 16 or damage the corrugated cardboard and the like.

Therefore, the present invention has been made to solve such a conventional problem, and is particularly applicable to a carrier for loading cargo, etc. It is easy to handle and waterproof so that rainwater etc. does not remain on the top curtain. It is a suggestion for ingredients.

[Means for Solving the Problems]

In order to solve the above-mentioned problems, the waterproofing device according to the present invention described in claim 1 has a top curtain of a size that can be mounted on at least the upper surface of a carrier for carrying luggage, and an attachment provided inside the top curtain. A waterproof cover having a section,
It is configured with a holder that can be inserted into and removed from the attachment portion, and the holder is configured as a curved ladder body, and in a state where the holder is attached to the attachment portion,
It is characterized in that the top curtain on the mounting portion projects upward.

According to the present invention, the waterproof cover and the holder attached to the waterproof cover constitute a waterproofing tool. The waterproof cover is a waterproof sheet made by processing a vinyl sheet or the like, and is composed of a sheet-like top curtain and a sheet-like curtain that is continuous with the top curtain, and the curtain is 4 pieces in consideration of use. Can be configured as a curtain piece. When the waterproof cover is attached to the carrier, the top curtain is configured to have a shape that is the same as or larger than the plane shape of the carrier, and the hanging piece covers the outer part of the carrier from the top of the carrier. As it hangs down, it can effectively protect the loaded cargo from rain.

Since the holder attached to the waterproof cover is made of a leaf spring having a curved arch shape, when the holder is attached (fixed) to the waterproof cover, the top curtain is projected upward. Become. As a result, the rain that has fallen on the waterproof cover does not stay on the top curtain, but drops as raindrops on the ground. In other words, there is almost no rain on the top curtain. As a result, even if the waterproof cover is removed from the carrier at the same time as the rain rises, the cargo does not collect on the top curtain and the cargo is wet with the rainwater, or the rainwater does not enter the inside of the cargo.

When the holder is attached to the waterproof cover,
Even when the waterproof cover is put on the carrier, since the shape of the waterproof cover is firm, even one person can easily put the waterproof device on the carrier. Therefore, its removal is also easy and can be attached to and removed from the carrier in a short time.

The mounting portion of the holding body may be a wrapping bag,
A fastener structure may be used. When used as a packaging bag, the holder can be freely attached and detached, and the attaching and detaching work can be easily performed. When the surface fastener structure is used, one of the surface fasteners is attached to the inside of the top curtain. For example, it is attached by sewing. The other of the surface fasteners is attached to the curved leaf spring that constitutes the holding body. Therefore, the other one of the hook-and-loop fasteners is in the form of a bag. The surface fastener can be attached not only to the curved leaf spring but also to all leaf springs constituting the holder. Even when it is attached to a curved leaf spring, it can be attached by dividing it into several parts.

The waterproofing device can be used not only as a rain shield but also as a sunlight shielding device for protecting luggage from direct sunlight.

【The invention's effect】

According to the present invention, since the holding body is further attached to the waterproof cover processed to fit the outer shape of the carrier, it is easy to attach and detach the waterproofing tool to the carrier. Therefore, the installation time and the removal time are short. As a result, even when it suddenly starts to rain, the loaded cargo can be covered without getting wet.

Since the top curtain is attached to this carrier in a state of protruding from the carrier by the holding body, the rainwater that has fallen down flows down without collecting on the top curtain. It has the practical benefit of being able to prevent accidents such as intrusion and damage to cargo by rainwater.

The holder is detachably attached to the waterproof cover, which is convenient when only the waterproof cover is to be replaced.

BEST MODE FOR CARRYING OUT THE INVENTION

Next, a preferred embodiment of the waterproofing device according to the present invention will be described in detail with reference to the drawings.

FIG. 1 is an exploded perspective view showing an example of a waterproofing tool 20 according to the present invention. The waterproofing tool 20 is for covering the upper part of the carrier 10, and is composed of a waterproof cover 20A and a holder 20B. To be done. As the waterproof cover 20A, a lightweight and easily processed waterproof sheet such as vinyl chloride or polyethylene sheet is used.

FIG. 1 shows the waterproof cover 20A in use, and its developed view is as shown in FIG. FIG. 3 is a rear view thereof. The waterproof cover 20A has a top curtain 22 having a shape substantially similar to the plane shape of the carrier 10 as shown in FIG.
Have. Therefore, when the carrier 10 has a rectangular shape (almost square shape) as shown in FIG. 1, the top curtain 22 is also a rectangular body having substantially the same size. In this example, the width is 110c
The size of the top curtain 22 is 1 in this example because it is applied to the carrier 10 having a size of m and a height of 180 cm.
It is chosen to be 20 cm square.

The top curtain 22 is provided with a hanging curtain 24 connected to the top curtain 22. In this example, four hanging curtain pieces 24, which are rectangular in shape and extend from their respective sides, correspond to the rectangular top curtain 22.
The curtain 24 is composed of A to 24D. Hanging pieces 24A-2
The left and right end faces (short side) of 4D are cut off as shown in the figure, and each end face (long side and short side) is formed with reinforcing folded portions 26a to 26d so as not to be loosened. Further, a plurality of through holes (for example, eyelet holes) 28 as shown in the figure are formed on the lower end surfaces of each of the hanging pieces 24A to 24D, and a string (not shown) is passed through so as to connect the through holes 28. , The curtain pieces 24A to 24D as the carrier 1
Can be securely fixed to the 0 side. As a result, the waterproofing tool 20 is strong against wind and rain. The length of the hanging pieces 24A to 24D is 5
About 0 cm is suitable, but its length varies depending on the height (180 cm) of the carrier 10 used, so
The dimensions are made to fit the carrier 10.

At the boundary between the top curtain 22 and the hanging curtain 24, as shown in FIG. 3, a fold line 23 may be provided from the back side of the top curtain 22. By attaching the folds 23, when the waterproofing device 20 is stored in a warehouse or the like, the hanging curtain 24 can be easily folded by using the folds 23 as a guide. As a result, it is easy to carry and the occupied area can be reduced even when it is stored.

Further, even when using the folded waterproofing tool 20, since the hanging curtain 24 can be unfolded from the fold 23, the waterproofing tool 20 can be unfolded without losing the shape of the top curtain 22. If the top curtain 22 can be expanded without losing its shape, the carrier 1
It becomes very easy to attach to 0, and the attachment work can be done smoothly.

In the above-mentioned example, the four curtains 24A-2
When the 4D is hung, the left and right end faces of the hanging pieces 24A to 24D are cut off so that the left and right end faces thereof do not overlap each other (shown by the broken line in FIG. 2). Slightly longer, 4 curtains 24A
When one of the end surfaces of the up to 24D is hung down, one end surface overlaps with the end surface of the adjacent hanging piece, and if a hook-and-loop fastener or the like is attached to the overlapping surface portion, four hook-and-loop pieces 24A can be used by using this hook-and-loop fastener. 24D can be connected to each other. As a result, depending on the wind, the curtain 24A
The hem of ~ 24D will not be turned up, and the protection against the cargo carried by the wind and rain will be perfect, and the measures against wind and rain will be even more reliable.

A mounting portion 30 for mounting and fixing a holding body, which will be described later, is provided substantially in the center of the back surface 22b of the top curtain 22 described above. As the mounting portion 30, it may be configured as a wrapping bag, or the mounting portion may be configured using a surface fastener or the like. The embodiment described below with reference to FIG. 3 shows a case where the mounting portion 30 is formed of a wrapping bag portion.

A packaging bag portion 30 as shown in FIG. 3 is provided at a substantially central portion on the back side of the top curtain 22. The bag portion 30 is for removably storing and fixing the holder 20B shown in FIG. 1. As shown in FIG. 4, it has a vinyl piece 32 attached or sewn to the top curtain 22.

The vinyl piece 32 is made of the same material as the waterproof cover. Then, one having a length substantially the same as the width WL of the top curtain 22 and a width of about 1/3 thereof is used, and the end face portion on the long side thereof is attached to the back surface 22b side of the top curtain 22. In this example, heat welding is performed as indicated by the broken line in FIG.
The vinyl piece 32 is heat-welded to the top curtain 22 to form the bag-shaped bag 30.

Even when the vinyl piece 32 is heat-welded, there is some margin so that the vinyl piece 32 does not adhere to the back surface 22b of the top curtain 22, that is, a space for packaging is created as shown in FIG. 4, for example. Thus, the vinyl piece 32 is welded. The allowance is a holding body 20 that is attached and fixed to the packaging bag portion 30.
Although it depends on the shape and size of B, in this example, a vinyl piece 32 having a length of 120 cm and a width of 42 cm is used.

Since the short side of the vinyl piece 32 is opened in the bag portion 30, the surface fasteners 34 and 36 shown in FIGS.
Are provided respectively to form a wrapping bag portion 30 that can be closed. Well-known fasteners (such as Velcro (registered trademark)) can be used for the surface fasteners 34 and 36,
Each of them is cut to have an appropriate length and width. FIG. 4 shows an example of the attachment. In FIG. 4, the surface fasteners 34a, 34b on the short sides are sewn and fixed to the corresponding portions of the top curtain 22 and the vinyl piece 32 so as to face each other. 32 pieces of vinyl by heat welding
May be fixed to the top curtain 22.

The hook-and-loop fasteners 34, 36 are the vinyl pieces 3
Although it is possible to make the length close to the length of the short side of 2,
With this configuration, the fasteners 34a and 34b facing each other are likely to stick to each other during the storage of the holder 20B inside the packaging bag 30, which may rather hinder the storage operation of the holder 20B. Therefore, as shown in the figure, the surface fasteners 34 and 36 are intentionally made shorter. Of course, instead of providing only one place in the opening, it is possible to disperse the fasteners in several places and attach the surface fastener.

The vinyl piece 32 is further provided with slit-shaped through holes 38 in the vicinity of both left and right ends thereof. These through-holes 38, 38 are provided in the holder 20 described later.
It is for penetrating a pair of hooks 44 attached to B so as to be exposed from the packaging bag portion 30.

FIG. 5 is a plan view showing an example of the above-mentioned holder 20B. The holding body 20B is a skeleton body having an arch shape as a whole. In this example, the holder 20B is composed of a leaf spring having a predetermined thickness and width. The holder 20B is shown in FIG.
As shown in FIG. 6, the structure is configured as a ladder-shaped skeleton (ladder), and the skeleton is curved as shown in FIGS. 6 and 7.
The body has a length of about 120 cm as described above and a width of about 42 cm.

Therefore, as shown in FIG. 5, the holder 20B has a pair of parallel curved leaf springs 40 (40A, 40A,
40B) and a plurality of, for example, three flat plate-shaped connecting plate springs 42 (42A, 42B, 42C) provided for connecting the curved plate springs 40A, 40B. The three connecting leaf springs 42 are non-curved leaf springs, and in this example, they are arranged at equal intervals, and the respective connecting portions are welded (spot welded or the like) as shown in FIG. Be converted. In the example shown in FIG. 5, the end faces of the two connecting leaf springs 42A, 42C are curved leaf springs 40A, 4C.
OB is welded to each end face.

As shown in FIG. 6, the curved leaf spring 40 is curved so as to form a predetermined angle α so that the height difference thereof is about 50 mm. The curved leaf spring 40 becomes linear when a force is applied in the downward arrow direction of FIG. 6, but when the force is removed, the curved leaf spring 40 returns (restores) to the curved shape as shown in FIG.

Both the curved leaf spring 40 and the connecting leaf spring 42 may be made of SUS304H steel. Further, both the curved leaf spring 40 and the connecting leaf spring 42 have a thickness of 1.5 mm and a width of 20 mm. A leaf spring having such a thickness and width is easy to process, has elasticity that can withstand the weight of the waterproof cover 20A, and has the necessary elasticity because the material itself is light, and the weight of the entire holding body 20B. Can be lightened.

Hooks 44 (44A, 44) as shown in FIG. 6 are formed on the lower surface of the connecting leaf springs 42A, 42C at the left and right ends of the connecting leaf spring 42, and near the center thereof.
B) is attached and fixed. The hooks 44 are for hooking the tops of the metal frames 10A and 10C of the carrier 10 shown in FIG. 1 to fix the holder 20B to the carrier 10.

In this example, as shown in FIG. 6, a leaf spring material having a substantially hook-like cross section (a shape of a slanting ladle) is used, and the connecting leaf springs 42A, 42A are arranged so as to face each other.
It is welded to the central lower surface of 42C. The curved portion of the hook 44 has an inner diameter corresponding to the thickness of the metal frames 10A and 10C of the carrier 10 so that the hook 44 does not rattle when hooked.

Now, the holder 20B having such a structure
Is stored in the above-mentioned packaging bag portion 30 and is used with the surface fasteners 34 and 36 of the packaging bag portion 30 closed,
The vertical cross-sectional shape of itself is as shown in FIG. 8, and the cross-sectional shape thereof is as shown in FIG. Since the holding body 20B has almost the same internal volume as the packaging bag portion 30, when the holding body 20B is housed in the packaging bag portion 30, the portion of the packaging bag portion 30 of the top curtain 22 is projected upward. To bend. With the curve of the packaging bag 30,
The entire top curtain 22 is similarly curved, and the entire top curtain 22 is shown in FIG.
, It will be inflated like an anpan.

The waterproofing tool 20 encloses the holder 20B in the wrapping bag portion 3
It is used when it is stored in 0. FIG. 10 shows an example of the usage state.

An example of use of the waterproofing tool 20 will be described below. First, the hanging pieces 24A to 24D are spread out from the folded waterproofing tool 20, and then the top curtain 22 is placed so that the wrapping bag portion 30 is inside.
Is covered from the upper surface side of the carrier 10. At that time, the hook 44 is fitted to the metal frame 10A or 10C of the carrier 10. For example, one hook 44A is fitted into the metal frame 10C. Then, attach the other hook 44B to the other metal frame 1
Fit in 0A.

By this work, the waterproofing tool 20 is fixed to the carrier 10. During this mounting work, the hanging pieces 24A to 24D are turned up and placed on the top curtain 22 side. After that, from the curtain piece 24A to the curtain piece 24
The parts up to D are sequentially hung down to the outside of the carrier 10. Figure 10
Indicates the state during this work.

After the hanging pieces 24A to 24D are hung down to the outside of the carrier 10, the end surfaces of the hanging pieces 24A to 24D are tied together by using a string if necessary. With this series of operations, the waterproofing tool 20 can be attached to the carrier 10.

Since the waterproofing tool 20 has a small number of constituent parts, namely the waterproof cover 20A and the holding body 20B, the entire waterproofing tool can be made extremely lightweight. With the above dimensions, it is about 1.5 kg. Therefore, the waterproofing tool 20 can be easily attached to and removed from the carrier 10. According to experiments, even an inexperienced person takes about 1 minute to install and remove. In other words, since the mounting and dismounting work can be performed very quickly, it is possible to quickly cope with a sudden rainfall and almost certainly protect the loaded cargo from rainwater.

When the carrier 10 is covered with the waterproofing tool 20, as shown in FIG. 11 and FIG.
Due to the action of 0B, the top curtain 22 is attached to the carrier 10 in a state of being bulged so that the whole is convex upward. As a result, the rainwater (raindrops) does not stay on the surface of the top curtain 22 and immediately drops through the curtain pieces 24A to 24D. When the waterproofing equipment 20 is removed from the carrier 10 after the rain has stopped, the operator may get wet with rainwater remaining on the top curtain 22, or this rainwater may enter the cargo 16 to be loaded, or the rainwater may cover it and stain the slip 18. You can clean up the problem.

The above-mentioned waterproofing equipment 20 can be prepared in several kinds depending on the size of the carrier 10, or a single waterproofing equipment 20 of a size which is always stocked in a warehouse. It can also cover all different careers.

As the sheet used as the waterproof cover 20A, a polyethylene sheet or the like can be used in addition to the embodiment. Even when a polyethylene sheet is used, a reinforcing thread is inserted in a mesh shape. Can be used. This is because it is less likely to be damaged.

It is expected that repeated use and storage of the waterproofing device 20 will increase the number of cases where the waterproof cover 20A is damaged. On the other hand, it is rare that the holder 20B is damaged. Since the holder 20B is configured to be separable from the waterproof cover 20A, in that case, it is sufficient to replace only the damaged waterproof cover 20A, and the maintenance fee is reduced.

The main purpose of the waterproofing device 20 is as a rain shelter. In addition to this, the waterproofing device 20 is positively used to protect the loaded cargo 16 from sunlight and to protect the loaded cargo 16 from rain and dew. It can also be used for. In addition, a waterproof cover 20A in which the sheet material is changed to make full use of its application
Can be prepared.

In the above-described embodiment, as a measure against wind and rain, it has been illustrated that a string is passed through the through holes 28 provided in the four hanging pieces 24A to 24D or a surface fastener is used. An example as shown in FIG. 13 is conceivable as a plan to utilize the through holes 28 provided in 24A to 24D.

In FIG. 13, for example, a connecting member 6 such as a rubber band is provided between the through holes 28 provided at the four corners and the casters 14.
Even if it is tied with 0, it will be a measure against wind and rain. By attaching one to several connecting members 60 to one hanging piece, it is possible to prevent the hanging pieces 24A to 24D from flipping up due to wind and rain.

As the elastic cord 61 as the connecting member 60, a string-shaped elastic cord or a bundle of elastic cords can be used, and metal hooks 62 and 63 are attached to the respective tip portions. . By hooking one metal hook 62 on the through hole 28 and hooking the other metal hook 63 on the leg of the caster 14 or the like, the curtain pieces 24A to 24A-2.
4D flapping can be avoided.

If a plurality of (for example, three) L-shaped auxiliary members 65 for hooking the metal hooks 63 as shown in FIG. 13 are attached to the side ends of the pedestal 12 and the bottom thereof, they can be connected. Since the work of attaching the member 60 is simplified and the entire hanging curtain pieces 24A to 24D can be stably hung down, it is a more complete measure against wind and rain. Instead of the elastic cord 61, a coil spring or a simple string may be used.

In the embodiment shown in FIG. 3 and subsequent figures, the wrapping bag portion is illustrated as an example in which the holder 20B is detachably attached and fixed to the waterproof cover 20A. The attachment part 30 may be formed of a surface fastener instead of the packaging bag part.

In this case, a plurality of surface fasteners (for example, Velcro (registered trademark)) are attached to predetermined positions on the back side 22b of the top curtain 22, and the surface surface of the leaf spring is surrounded by the surface fasteners. The spring and hence the holder 20B are attached and fixed to the back surface 22b of the top curtain 22. FIG. 14 shows a specific mounting example of the surface fastener 50.

In this example, the curved leaf springs 40A, 40 are located at the position where the holder 20B should be attached to the back surface 22b.
In order to fix the vicinity of both ends of B to the top curtain 22, in this example, 4
Along with the use of individual surface fasteners 50A-50D,
A hook-and-loop fastener 50E for fixing the central connecting leaf spring 42B of the connecting leaf springs 42 to the top curtain 22 is used.

These surface fasteners 50A to 50E are strip-shaped surface fasteners, respectively, and are curved leaf springs 4.
Face fasteners 5 near both ends of 0A and 40B (4 places)
0A to 50D are attached. Surface fastener 50A ~
Since 50E has the same structure, the surface fastener 5
The configuration will be described using 0B.

As shown in FIG. 15, the surface fastener 50B is a female (or male) surface fastener 52.
a and a male (or female) surface fastener 52b
And a rectangular female fastener 52a having a rectangular shape.
The female surface fastener 52 a is attached to the back surface 22 b of the top curtain 22 by, for example, being sewn to the top curtain 22.

On the other hand, the male surface fastener 52b
Is attached to one end of a strip-shaped strip 54 having a predetermined length, and the other end of the strip 54 is the back surface 22b of the top curtain 22 as shown in FIG.
It is attached and fixed to the top curtain 22 by means of, for example, suturing at a slight interval w so as to be parallel to 2a.

As the male surface fastener 52b, one having the same shape as or slightly larger than the female surface fastener 52a is used. In FIG. 15, a slightly larger male surface fastener 52b is used. The length of the band 54 is
In consideration of the stitching position of the band 54, when the leaf spring is surrounded, the length is selected so that the leaf spring can be surrounded and fixed without slack.

Other surface fasteners 50A, 50C to 50E
Is similarly configured. The hook-and-loop fastener 50E with respect to the connecting leaf spring 42B is attached and fixed at a position capable of holding substantially the middle portion of the connecting leaf spring 42B.

When the holder 20B is attached to the top curtain 22, as shown in FIG. 14, the curved leaf springs 40A and 40B and the connecting leaf spring 42 are overlapped with each other so as to overlap the other end surface side of the belt 54.
Position the placement position of B. In this state, the band 54 is turned in the direction of the arrow a so that the female surface fastener 52a is combined with the male surface fastener 52b. At this time, the band 54 is tightly tightened so as to be surrounded so as to be in close contact with the leaf spring. By doing so, the holding body 20B is attached and fixed to the back surface 22b of the top curtain 22 in a state in which the holding body 20B is completely in close contact with the back surface 22b. Therefore, when the waterproof cover 20A is in use, the curved leaf springs 40A and 40B.
By the action of, the carrier 10 with its top curtain 22 curved
Will be attached to.

Incidentally, it is preferable that the mounting interval w between the female surface fastener 52a and the band 54 to which the male surface fastener 52b is mounted be as narrow as possible. This is because the smaller side w is due to the male side fastener 52b,
This is because the leaf springs 40 and 42 can be tightly tightened.

The number of hook-and-loop fasteners 50 to be used, their arrangement position, and the like can be set arbitrarily. For example, connecting leaf spring 4
It is also possible to attach a pair of surface fasteners to both the curved leaf springs 40A and 40B, which are close to 2B. The size of the hook-and-loop fastener 50 is also arbitrary and is not limited to the strip shape as illustrated.

In addition to the waterproof cover, the waterproof device 20 can also be used as a sunlight shielding device for protecting the luggage loaded on the carrier 10 from direct sunlight.
