Therefore, when the band 3a and the fixed structure 3 are provided as the fixed structure 3, there is also an effect that the load loaded on the slide cart 8 can be prevented from collapsing when the protective sheet 2 is attached or detached.

The fixing structure 3 in the load collapse prevention tool 1 according to the present embodiment does not necessarily have to include the band 3a and the annular tool 3c as described above, and supplements the length of the protective sheet 2 as necessary. A configuration other than the above can be used as long as it can be configured so that the degree of tightening of the luggage by the protective sheet 2 can be adjusted. For example, as the fixing structure 3, a quick release type joint in which the length of the belt can be adjusted can be used.
Further, in the load collapse prevention tool 1 according to the present embodiment, the case where two sets of the band 3a and the annular tool 3c are provided as the fixing structure 3 is described as an example, but the band 3a and the ring tool 3c are described as one set. It suffices to have the above desired number of sets. However, as the number of sets of the band 3a and the ring tool 3c increases, the work of attaching and detaching the protective sheet 2 becomes complicated. Therefore, it is desirable that the number of sets of the band 3a and the ring tool 3c be kept to the minimum necessary.

Further, in the load collapse prevention tool 1 according to the present embodiment, when the fixing structure 3 is composed of the band 3a and the annular tool 3c as described above, when the load collapse prevention tool 1 is used, the protective sheet 2 and the band 3a are used. A large tension acts on the connection part.
Therefore, in the load collapse prevention tool 1 according to the present embodiment, there is a concern that problems such as the band 3a being torn off easily occur at the connection portion between the protective sheet 2 and the band 3a.
In view of such circumstances, in the load collapse prevention tool 1 according to the present embodiment, the winding core 5 arranged at the end of the protective sheet 2 and the band 3a are integrally fixed in a laminated state. That is, the load collapse prevention tool 1 according to the present embodiment includes a laminated region 3b in which the take-up core 5 and the band 3a are integrally fixed in an overlapping state (see FIGS. 2 and 3).
As described above, since the load collapse prevention tool 1 according to the present embodiment includes the laminated region 3b in which the winding core 5 and the band 3a overlap, the winding core 5 is connected to the protective sheet 2 and the band 3a. It can also be used as a reinforcing material in.
As a result, the durability of the load collapse prevention tool 1 according to the present embodiment can be improved.

Further, although not particularly shown, the pocket 6 of the load collapse prevention tool 1 according to the present embodiment may be provided with a second pocket or a seal sticking table on the upper surface thereof (both are optional components).
When the pocket 6 of the load collapse prevention device 1 according to the present embodiment has a second pocket on the upper surface thereof, the slide cart 8 and the luggage loaded therein are described in the second pocket. Documents can be stored.
In this case, by forming the second pocket with a transparent material, the information of the above-mentioned documents can be visually confirmed without being taken out from the second pocket.

Further, even when the pocket 6 of the load collapse prevention tool 1 according to the present embodiment is provided with a sticker sticking table on the upper surface thereof, a sticker on which information about the slide cart 8 and the load loaded therein is written is stuck. be able to. In this case as well, the user can obtain information on the slide cart 8 and the load loaded on the slide cart 8 simply by looking at the upper surface side of the pocket 6 of the load collapse prevention device 1.
As the seal sticking table, a sheet body (for example, a textured sheet or the like) can be used in which the detachability of the seal is appropriately adjusted by, for example, embossing the surface.

Therefore, when the pocket 6 of the load collapse prevention tool 1 according to the present embodiment is provided with a second pocket or a seal sticking table on the upper surface thereof, the load collapse prevention tool 1 is permanently installed on the slide cart 8. It is possible to send information about the slide cart 8 and the luggage loaded on the slide cart 8 together with the preventive device 1.
As a result, the convenience of the load collapse prevention tool 1 according to the present embodiment can be improved.

Further, the load collapse prevention tool 1 according to the present embodiment has a hook 4a as a holding structure 4 for detachably attaching the protective sheet 2 of the portion provided with the pocket 6 to the side panel 10 of the slide cart 8. I have.
The hook 4a is formed by, for example, forming a shape-retaining synthetic resin having a J-shaped cross section and sewing it at a desired position on the protective sheet 2. It is not particularly necessary to specify the method of attaching the hook 4a to the protective sheet 2 for sewing. However, when a cloth, a non-woven fabric, a synthetic resin sheet material, or the like is used as the material of the protective sheet 2 or the pocket 6, and the pocket 6 or the band 3a is sewn and fixed to the protective sheet 2, it is a part of the work. The hook 4a can be sewn onto the protective sheet 2 and fixed. Therefore, when the hook 4a as described above is used as the holding structure 4, the productivity of the load collapse prevention tool 1 according to the present embodiment can be improved.
When the hook 4a as shown in FIGS. 1, 2, and 6 is used as the holding structure 4, the load collapse prevention tool 1 can be attached to and detached from the side panel 10 of the slide cart 8 with one touch.
Further, as the holding structure 4, a metal hook or the like can be used without any trouble in addition to the hook 4a as described above. In this case, although it may be necessary to change the method of mounting on the protective sheet 2, it is possible to provide the holding structure 4 having more durability.

On the other hand, when a hook (for example, hook 4a or the like) is used as the holding structure 4 of the load collapse prevention tool 1 according to the present embodiment, the place where the load collapse prevention tool 1 can be installed is the horizontal member 10b on the side panel 10. Another problem arises that it is specified in.
In such a case, instead of using a hook (for example, hook 4a) as the holding structure 4 of the load collapse prevention tool 1, the protective sheet 2 on the back side of the pocket 6 is provided with a fixing tool (for example, a hook-and-loop fastener). A band, a fixing string, or the like is attached, and this band is wound around the vertical material 10a of the side panel 10, or the fixing string is fastened to the vertical material 10a, so that the desired position in the vertical direction of the side panel 10 is obtained. It may be configured so that the load collapse prevention tool 1 can be installed (arbitrarily selected component).
In this case, the convenience of the load collapse prevention tool 1 according to the present embodiment can be further improved.

Further, in the load collapse prevention tool 1 according to the present embodiment, although not particularly shown, the holding structure 4 of the protective sheet 2 is wound around the above-mentioned hook (for example, hook 4a or the like) and the vertical material 10a of the side panel 10. A band for holding the protective sheet 2 or a string for binding may be used together. More specifically, a hook (for example, a hook 4a) is provided on the back surface (protective sheet 2) on the vertically upper side of the pocket 6, and the side panel 10 is vertically provided on the back surface (protective sheet 2) on the vertically lower side of the pocket 6. A holding structure 4 made of a band or a string that is wound and fixed to the material 10a or the horizontal material 10b may be provided.
In this case, as compared with the case where the load collapse prevention tool 1 according to the present embodiment includes only a hook (for example, hook 4a or the like) as the holding structure 4, when the load collapse prevention tool 1 is permanently installed on the slide cart 8, the side surface thereof is used. There is an advantage that the load collapse prevention tool 1 can be made difficult to come off from the panel 10.
In this case, it is possible to prevent the load collapse prevention tool 1 from coming off or being lost due to dropping when the load collapse prevention tool 1 according to the present embodiment is permanently installed on the slide cart 8.

Further, in the present embodiment, a case where a region of less than 50% in the vertical direction of the slide cart 8 is covered with the protective sheet 2 is described as an example, but instead of such a protective sheet 2, a slide is described. The protective sheet 2 may be provided so as to cover a region of 50% or more in the vertical direction of the cart 8 (optional component).
Generally, when a load is transported by a slide cart 8, the load arranged vertically above is more likely to collapse. Therefore, if the protective sheet 2 is wound around the load vertically above the slide cart 8, most of the load collapse during transportation by the slide cart 8 can be prevented.
On the other hand, when 1 according to the present embodiment includes a protective sheet 2 capable of covering a region of 50% or more in the vertical direction of the slide cart 8, the slide cart 8 is more reliably compared to the case where it is not provided. It is possible to prevent the load of the luggage transported by the above from collapsing.

Although the material of the protective sheet 2 according to the present embodiment is not particularly specified, it is desirable to use a cloth from the viewpoint of strength and durability.
Further, if the thickness of the protective sheet 2 is large, the durability and strength are improved, but the protective sheet 2 wound around the take-up core 5 becomes bulky, and when it is permanently installed in the slide cart 8 in the stored state, It is not preferable because there is a concern that it may interfere with the operation of the slide cart 8.
In view of these circumstances, the thickness of the protective sheet 2 constituting the load collapse prevention tool 1 is substantially the same as the internal dimension A (see FIG. 1) of the vertical member 10a constituting the side panel 10 of the slide cart 8. It is preferable to set the dimension L ₁ (see FIG. 4) of the protective sheet 2 when wound around the winding core 5 to be equal to or less than the width A ₁ (see FIG. 1) of the side panel 10.
In this case, even when the protective sheet 2 wound around the winding core 5 is housed in the pocket 6, the horizontal width L ₂ of the pocket 6 (see FIG. 6) is the width A ₁ of the side panel 10 (FIG. 1). See)). As a result, when the load collapse prevention tool 1 according to the present embodiment is permanently installed in the slide cart 8, it is possible to more reliably prevent the load collapse prevention tool 1 from interfering with the operation of the slide cart 8.

Further, in the load collapse prevention tool 1 according to the present embodiment, the case where the planar shape of the winding core 5 is rectangular is described as an example, but the planar shape of the winding core 5 is the above rectangular shape. It may be in the shape of a square cut out from the central part of the above, or it may be in the shape of a U. However, when the planar shape of the take-up core 5 is U-shaped, the notch portion of the take-up core 5 is not arranged on the longitudinal end edge side of the protective sheet 2, that is, the entire area of the longitudinal end edge of the protective sheet 2. Must be equipped with a take-up core 5.
Even when the planar shape of the winding core 5 of the load collapse prevention tool 1 according to the present embodiment is made into a square shape or a U shape as described above, the width of the winding core 5 in the winding direction of the protective sheet 2 is formed. L needs to satisfy 0.5A ≦ L ≦ A when the internal dimension A of the vertical material 10a in the side panel 10 of the slide cart 8 is 1.

As described above, the present invention can suitably prevent the load from collapsing when the load is transported by the slide cart, can be easily attached to and detached from the slide cart, and can be stored compactly when not in use. It is a load collapse prevention tool that can be installed permanently on the slide cart and does not interfere with the operation of the slide cart, and can be used in the technical fields related to logistics and logistics equipment.
