[Configuration of this embodiment]
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
1 and 2, the cargo holding sheet 1 of this embodiment is for holding down an upper surface 61 and both end surfaces 62 of a cargo 6 on a pallet 5, and comprises a sheet body 10, end connectors 20 attached to both end portions 11 of the sheet body 10 and connectable to connecting holes 51 as connecting portions of the pallet 5, and a length-adjustable sheet length adjustment body 30 attached at two locations facing each other in the longitudinal direction of the sheet body 10 between the both end portions 11 of the sheet body 10.
In the following description, the longitudinal direction of the load-holding sheet 1 is defined as the X-axis direction, the width direction of the load-holding sheet 1 as the Y-axis direction, and the up-down direction as the Z-axis direction. The X-, Y-, and Z-axis directions are perpendicular to each other. Fig. 2(A) shows a plan view of the load-holding sheet 1, and Fig. 2(B) shows a side view of the load-holding sheet 1.

In this embodiment, the pallet 5 is composed of a pallet body 50 having connection holes 51 at both ends, and poles 52 standing up from both side edges continuing to both ends of the pallet body 50. The connection holes 51 are formed by holes through which belts 21, which will be described later, are passed. In addition, on the pallet body 50, cargo receiving plate materials 53 such as plastic corrugated cardboard are arranged along the poles 52.
The cargo 6 may be, for example, a plurality of long pieces of construction timber loaded on the pallet 5. The positional deviation of the cargo 6 in the Y-axis direction is suppressed by the pole 52 and the cargo receiving plate material 53 receiving the cargo 6 in the Y-axis direction.

The sheet body 10 has both ends 11 woven with 600D polyester fibers to provide high strength, and the area between the ends 11 is made of an elastic material such as polyvinyl chloride that can stretch about 1.3 times in the X-axis direction. The dimension of the end 11 in the X-axis direction is about 150 mm. The end 11 is provided with a rod-shaped rigid member 15 made of metal such as aluminum or steel, wood, or high-rigidity synthetic resin, along both edges of the end 11 in the Y-axis direction. In this embodiment, the length dimension of the sheet body 10 in the X-axis direction is about three times its width dimension in the Y-axis direction. For example, the length dimension may be about 3000 mm and the width dimension may be 1000 mm, but the dimensions are not limited to these and are appropriately set according to the dimensions of the pallet 5 and the cargo 6 to be loaded thereon. The length dimension of the rigid member 15 in the Y-axis direction is about 950 mm.

In this embodiment, a pair of end connectors 20 are provided at a distance in the Y-axis direction from the end 11 of the sheet body. One end connector 20 is disposed on one edge of the end 11 in the Y-axis direction, and the other end connector 20 is disposed on the other edge of the end 11 in the Y-axis direction.
The end connector 20 includes a belt 21 and a buckle 23 as an adjustment member attached to the belt 21. The belt 21 is, for example, a strip woven with synthetic resin fibers, and has a width of about 250 mm in this embodiment. The buckle 23 includes a plug 24 and a socket 25 into which the plug 24 is inserted and engaged. The socket 25 is attached to one end of the belt 21, and the plug 24 is attached to a portion (the other end side of the belt 21) spaced apart from the one end of the belt 21 along the belt 21. The belt attachment portion of the plug 24 is formed in a hook shape having a pair of holes through which the belt 21 passes and a shaft portion disposed between the pair of holes and around which the belt 21 is hung, and is configured to be adjustable (adjustable) in the length of the belt 21 between the plug 24 and the socket 25. A general-purpose buckle with an adjuster function can be used as the buckle 23.
Here, a female member 41 of a hook-and-loop fastener 40 is provided at the end 11 of the sheet body 10, and a male member 42 of the hook-and-loop fastener 40 is provided at the other end of the belt 21, the female member 41 having a hook-shaped engaging portion and the male member 42 having a loop-shaped engaged portion. The remaining portion of the belt 21 from the portion attached to the plug 24 to the other end is stored so as not to hang down by engaging the male member 42 with the female member 41. The male member 42 can also be peeled off from the female member 41.

The seat length adjustment body 30 includes two belt length adjustment bodies 36 each having a belt 31, 32 and a buckle 33 with an adjuster function that connects the belts 31, 32, and band-shaped attachment bodies 37, 38 that attach the belts 31, 32 to the seat body 10. The two belt length adjustment bodies 36 are arranged at a distance in the Y-axis direction. The belts 31, 32 have approximately the same width and configuration as the belt 21, and the buckle 33 has approximately the same configuration as the buckle 23. The attachment bodies 37, 38 are made by weaving synthetic fibers made of polypropylene, and have a width of 50 mm.
The mounting body 37 is disposed about 800 mm away in the X-axis direction from one end 11 of the seat body 10, and the mounting body 38 is disposed about 800 mm away in the X-axis direction from the other end 11 of the seat body 10. The dimension in the X-axis direction between the mounting bodies 37, 38 is about 950 mm.
One end of the belt 31 is attached to the attachment body 37 by sewing or the like, and one end of the belt 32 is attached to the attachment body 38 by sewing or the like. The belt 31 is about 100 mm long, and a socket 35 of a buckle 33 is attached to the other end. The belt 32 is about 1200 mm long, and a plug 34 of the buckle 33 is attached to the other end. The plug 34 is constructed substantially similarly to the plug 24, so the length of the belt 32 can be adjusted.

The procedure for installing the load holding sheet 1 according to this embodiment will be described below.
First, the sheet body 10 is placed over cargo 6 such as construction lumber piled up on a pallet 5, covering an upper surface 61 of the cargo 6 and the upper portions of both end surfaces 62 of the cargo 6 up to about the vertical center portions. The length dimension of the sheet body 10 is adjusted to an appropriate length in advance by adjusting the length of the belt 32 using the adjuster function of the buckle 33 of the belt length adjustment body 36.
Next, the end connectors 20 attached to both ends 11 of the seat body 10 are connected to the connection holes 51 of the pallet 5. Specifically, the belt 21 is passed through the connection hole 51 and the plug 24 is inserted into the socket 25 for engagement.
Finally, the length of the belt 21 is adjusted by the adjuster function of the buckle 23, thereby pulling the sheet body 10 while narrowing the gap between the end 11 of the sheet body 10 and the connecting hole 51 of the pallet 5. The sheet body 10, which is stretched in this way, applies tension to the upper surface 61 and both end surfaces 62 of the luggage 6 while pressing them down. The sheet body 10 covers the upper surface 61 of the luggage 6 and about 70% of the area from the upper parts of both end surfaces 62. Here, about 30% of the lower areas of both end surfaces are exposed and not covered by the sheet body 10, but the load of the upper parts of the luggage 6 is applied to them, so that the loaded cargo is less likely to shift position even during transport.
As described above, any excess portion of the belt 21 due to the length adjustment is held in place by the hook-and-loop fastener 40 so that it does not hang down.
The load holding sheet 1 is installed in this manner.

[Modification]
In the above embodiment, the seat length adjustment member 30 is provided, but when the seat body 10 is used in an environment where it is not necessary to adjust the seat length, the seat length adjustment member 30 may be omitted.
In the above embodiment, a rigid member 15 is provided at the end 11 of the sheet body 10, but the rigid member 15 may be omitted, for example, in cases where the end 11 is of high strength and is configured so as to be unlikely to bend even when pulled by the belt 21, or in cases where multiple belts 21 are used to pull the end 11 so as to be unlikely to bend.
In the above embodiment, there are two end connectors 20 attached to one end 11 of the seat body 10, but there may be three, or there may be only one if the width dimension of the belt 21 is large.
In the above embodiment, a hook-and-loop fastener 40 is provided to store the excess portion of the belt 21, but in a usage environment where the excess portion of the belt 21 does not hang down long enough to touch the ground, the hook-and-loop fastener 40 may be omitted.
In the above embodiment, the end connector 20 is configured to include a belt 21 and a buckle 23 with an adjuster function. However, for example, the belt 21 may be provided with a connector such as a hook that can be connected to the pallet 5, and an adjuster such as a hook that can adjust the belt length may be attached to the belt 21 as an adjustment member instead of the buckle 23.

[Summary of the invention]
The cargo holding sheet of the present invention is a cargo holding sheet for holding down the top surface and both end surfaces of cargo on a pallet, and comprises a sheet body that is stretchable in the longitudinal direction, and end connectors that are attached to both longitudinal ends of the sheet body and can be connected to the connected portions of the pallet, and are characterized in that the end connectors are configured so that the distance between the end of the sheet body and the connected portions of the pallet can be adjusted when connected to the pallet.
The load-holding sheet of the present invention can be installed by covering the top and both end surfaces of the cargo on the pallet, connecting the end connectors to the connected parts of the pallet, and adjusting the distance between the sheet body and the connected parts of the pallet. Since the sheet body is stretchable, compared to using a non-stretchable sheet, the sheet body can be stretched in the longitudinal direction by adjusting the end connectors to firmly hold down the top and both end surfaces of the cargo, thereby preventing the cargo from shifting to the both end surfaces on the pallet and causing it to collapse. In addition, there is no need to install a net or the like in addition to the load-holding sheet, which reduces the burden of the load-holding work.
In addition, by repeatedly using the cargo holding sheet of the present invention, the amount of packaging material to be discarded can be reduced compared to when packaging materials for holding cargo are used disposable.
The above-mentioned pallet may be composed of a pallet body having connecting parts at both ends and poles standing up from both side edges continuing to both ends of the pallet body. In this case, the poles support both sides of the cargo along both side edges of the pallet, so that the cargo is prevented from shifting out of position to both sides. Furthermore, a cargo support plate such as plastic cardboard may be placed between the cargo and the poles.

The load-holding sheet of the present invention may further include a length-adjusting sheet length adjuster attached to two positions facing each other in the longitudinal direction of the sheet body between both ends of the sheet body.
With this configuration, for example, if there is only a small amount of cargo on the pallet and the seat body is too long for that cargo, the seat length adjustment body can be shortened to move the portion of the seat body between the two points where the seat length adjustment body is attached, and the seat body can be adjusted to an appropriate length. Also, since the portions between the two points where the seat length adjustment parts are attached to the seat body and both ends of the seat body are in an expandable state, the seat body can be stretched by adjusting the end connectors as described above, and the top surface and both end surfaces of the cargo can be firmly pressed down.

In the load-holding sheet of the present invention, the end connector comprises a belt that is smaller than the dimension of the end in a width direction intersecting the longitudinal direction of the sheet body, and a rigid member may be provided along the width direction at the end of the sheet body.
With this configuration, in order to uniformly stretch the entire width of the sheet body in the longitudinal direction when narrowing the gap between the end of the sheet body and the connected portion of the pallet using the end connector, it is necessary to install multiple belts along the width direction of the end of the sheet body.However, by providing the rigid member described above, the entire width direction of the end of the sheet body can be stretched even if the number of belts installed is reduced, and the cargo on the pallet can be properly held down.

In the load-holding sheet of the present invention, the end connector comprises a belt that is smaller than the dimension of the end in a width direction intersecting the longitudinal direction of the sheet body, and at least two of the end connectors may be attached to the end of the sheet body at intervals in the width direction.
With this configuration, the risk of the end of the sheet body tilting can be reduced compared to, for example, a case in which a single end connector is attached to the end of the sheet body, and the installed state of the load-holding sheet can be stabilized.

In the cargo holding sheet of the present invention, the end connector comprises a belt and an adjustment member for adjusting the length of the belt, and may further comprise a hook-and-loop fastener that can be attached and detached to the end of the sheet body to hold the excess portion of the belt adjusted by the adjustment member.
With this configuration, the distance between the end of the seat body and the pallet can be adjusted by adjusting the position of the buckle relative to the belt, and the excess portion of the belt can be bundled up by attaching the end of the belt to the end of the seat using a hook-and-loop fastener.
