Description

[Technical Field]

[0001] The present invention relates to a band fastener for a pallet. [Background technology]

[0002] Conventionally, when loading cargo onto a pallet transported by a forklift, methods such as wrapping the cargo in plastic wrap have been used to secure the cargo. However, this method does not provide a stable way to secure the cargo, and there is a risk of the cargo falling over.

[0003] Another known method for securing cargo on a pallet is to tie down and secure the cargo with bands. Specifically, the cargo is secured to the pallet with bands hooked through grid-like holes in the pallet top. While this method securely secures the cargo, it requires the bands to be threaded through and removed from the grid-like holes each time cargo is loaded, making it cumbersome to use. Furthermore, the grid-like holes are located on the pallet top, and when securing the cargo with the bands, it is not possible to load cargo outside the grid-like holes. This prevents the pallet top surface from being fully utilized for loading cargo, resulting in reduced loading efficiency.

[0004] Patent Document 1 discloses a fastener that can be easily used and can stably secure cargo on a pallet. The fastener includes a top plate and a bottom plate that can contact the upper surface and underside of the pallet's top plate, a rope hook plate extending from the top plate, and two screws arranged on the bottom plate. When the cargo is secured with the bands, the screws on the bottom plate bite into the underside of the top plate, ensuring a secure fit. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 6-263378 Summary of the Invention [Problem to be solved by the invention]

[0006] The invention described in Patent Document 1 ensures stable cargo fixing and ease of use. However, because the upper plate of the fixing device is placed on the top surface of the pallet top plate and cargo cannot be loaded on the outer portion of the pallet top plate beyond the rope hook plate, even with the invention described in Patent Document 1, it is still not possible to make the most effective use of the pallet top surface area for loading cargo.

[0007] Therefore, the prior art and inventions disclosed in prior art documents are unable to easily and stably secure cargo in a manner that makes the most effective use of the top surface area of ​​the pallet.

[0008] An object of the present invention is to provide a band fastener for a pallet that can be easily used and can stably fasten cargo while making the most effective use of the loadable area. [Means for solving the problem]

[0015] Hereinafter, one embodiment of a band fastener for a pallet according to the present invention will be described.

[0016] In this specification, the "outside" of a pallet band fastener refers to the side that faces the entrance of the fork insertion hole when the pallet band fastener is attached to the pallet, and the "inside" refers to the opposite side. Furthermore, the "longitudinal direction" refers to the direction connecting the outside and inside, the "width" refers to the direction perpendicular to the longitudinal direction in a plane parallel to the pallet placement surface, and the "height" refers to the direction perpendicular to the longitudinal and width directions.

[0017] As shown in FIG. 7, a pallet 2 used to place cargo has fork insertion holes 20 into which the forks of a forklift can be inserted to enable movement by a forklift. Typically, the fork insertion holes 20 are located on the side of the pallet 2. A plurality of lattice holes 21 are provided on the upper surface of the fork insertion holes 20. The plurality of lattice holes 21 are used to pass and hook bands 3 or ropes for securing cargo. In other words, the plurality of lattice holes 21 penetrate through the top plate of the pallet 2 and the upper surface of the fork insertion holes 20. The plurality of lattice holes 21 are also located around the edge of the top plate of the pallet 2. The pallet 2 has a lattice portion 22 that forms the plurality of lattice holes 21. The pallet band fastener 1 of this embodiment is used to fasten cargo placed on a pallet 2 to the pallet 2.

[0018] As shown in FIG. 1, the pallet band fastener 1 of this embodiment includes a rectangular plate member 10. 2, the plate member 10 has a first region 101 having a plurality of extension portions 11 extending perpendicularly to the plate member 10, and a second region 102 having openings 12. The first region 101 and the second region 102 are arranged side by side in the longitudinal direction. The multiple extension portions 11 include a pair of first extension portions 11a arranged at both ends of the first region 101 in the width direction perpendicular to the longitudinal direction, and a pair of second extension portions 11b arranged at a distance from the first extension portions 11a in the longitudinal direction and arranged at both ends of the first region 101 in the width direction. The opening 12 is located in the center of the second region 102 .

[0019] The first region 101 and the second region 102 are disposed continuously in the longitudinal direction. Specifically, the first region 101 is disposed on the inner side in the longitudinal direction, and the second region 102 is disposed on the outer side in the longitudinal direction.

[0020] 3, the plurality of extension portions 11 may extend substantially perpendicular to the plate member 10. That is, the plurality of extension portions 11 may extend at an angle of 90±5 degrees with respect to the plate member 10. It is preferable that the plurality of extension portions 11 extend at an angle of 90 degrees.

[0021] The first extending portion 11a is disposed on the inner side in the longitudinal direction of the first region 101. The second extending portion 11b is disposed on the outer side in the longitudinal direction of the first region 101. Alternatively, the first extending portion 11a may be disposed on the inner end of the first region 101 in the longitudinal direction, and the second extending portion 11b may be disposed on the outer end of the first region 101 in the longitudinal direction.

[0022] The first extending portion 11a and the second extending portion 11b are formed in a plate shape and are arranged such that the flat portions of the first extending portion 11a and the second extending portion 11b are parallel to the longitudinal direction.

[0023] The length in the height direction of the plurality of extensions 11 is 20 mm or more, preferably 25 mm or more, and more preferably 28 mm or more, and the length in the height direction of the plurality of extensions 11 is 40 mm or less, preferably 35 mm or less, and more preferably 32 mm or less. Here, the height of the plurality of lattice holes 21 exceeds at least 40 mm. In other words, since the height of the plurality of extension portions 11 is within the above range, when the plurality of extension portions 11 are inserted into the plurality of lattice holes 21, the plurality of extension portions 11 do not protrude above the top plate of the pallet 2. Therefore, if the height direction length of the plurality of lattice holes 21 is outside the above range and exceeds the upper limit of the above range, the plurality of extension portions 11 may protrude above the top plate of the pallet 2, hindering stable fastening of cargo placed on the pallet 2. On the other hand, if the height direction length of the plurality of lattice holes 21 is outside the above range and falls below the lower limit of the above range, the pallet band fastener 1 cannot be sufficiently fastened to the pallet 2 when attached to the pallet 2.

[0024] The longitudinal length of the plurality of extensions 11 is 5 mm or more, preferably 8 mm or more, and more preferably 11 mm or more, and the longitudinal length of the plurality of extensions 11 is 19 mm or less, preferably 16 mm or less, and more preferably 13 mm or less. Here, for a typical pallet, the longitudinal length of the plurality of lattice holes 21 is between 20 mm and 25 mm. Therefore, the longitudinal length of the plurality of extension portions 11 is shorter than the longitudinal length of the plurality of lattice holes 21, and is substantially the same as the longitudinal length of the plurality of lattice holes 21. In other words, by having the longitudinal lengths of the plurality of extension portions 11 within the above range, it is possible to prevent the pallet band fastener 1 from falling out of the plurality of lattice holes 21 before the pallet band fastener 1 is locked into the plurality of lattice holes 21.

[0025] 10, the opening 12 is used to pass the band 3 through and hook the band 3 onto the pallet band fixing device 1. In other words, the band 3 is attached to the opening 12.

[0026] The opening 12 may be disposed on the outer side of the second region 102 in the longitudinal direction, or on the inner side of the second region 102 in the longitudinal direction. In addition, the opening 12 is preferably disposed at the center of the second region 102 in the width direction.

[0027] The plurality of extension portions 11 can be inserted into and removed from the plurality of lattice holes 21 . First, as shown in FIG. 10 , by inserting the multiple extension portions 11 into the multiple lattice holes 21, the lattice portion 22 is sandwiched between the first extension portion 11a and the second extension portion 11b. Next, by pulling the plate member 10 outward in the longitudinal direction via the band 3 attached to the opening 12, stress is generated between the multiple extension portions 11 and the lattice portion 22, and the pallet band fastener 1 is engaged with the multiple lattice holes 21. Thereafter, by ceasing to pull the plate member 10 outward in the longitudinal direction, stress is released between the multiple extension portions 11 and the lattice portion 22, and the pallet band fastener 1 is released from the multiple lattice holes 21. This allows the pallet band fastener 1 to be easily attached to and detached from the pallet 2 without any special processing of the pallet 2.

[0028] When the pallet band fastening device 1 according to this embodiment is attached to a pallet 2, part or all of the pallet band fastening device 1 is fixed inside the fork insertion holes 20. In other words, the pallet band fastening device 1 is not fixed on the surface of the pallet top. As a result, the path of the bands 3 when fastening cargo is the surface of the pallet top, and does not pass inside the peripheral edge of the pallet top, so cargo can be fastened while making the most effective use of the loadable area of ​​the pallet 2.

[0029] 3, the first extending portion 11a may include a first protrusion 110a protruding in the longitudinal direction, and the second extending portion 11b may include a second protrusion 110b protruding in the longitudinal direction. The first protrusion 110a may protrude outward in the longitudinal direction from the first extending portion 11a, and the second protrusion 110b may protrude inward in the longitudinal direction from the second extending portion 11b. The first protrusion 110a and the second protrusion 110b are preferably arranged so as not to face each other, and more preferably so that the second protrusion 110b is positioned farther from the plate member 10 than the first protrusion 110a. Arranging the first protrusion 110a and the second protrusion 110b so as not to face each other means that the first protrusion 110a and the second protrusion 110b are not arranged at overlapping positions in the height direction.

[0030] By arranging the first protrusion 110a and the second protrusion 110b as described above, the gap formed between the first protrusion 110a and the second protrusion 110b is wider than when the first protrusion 110a and the second protrusion 110b are arranged facing each other, making it easier to pass the lattice portion 22 through the gap, and therefore easier to attach the pallet band fastener 1 to the pallet 2. Furthermore, because the first protrusion 110a and the second protrusion 110b come into contact with the lattice portion 22, stress is generated between the first extension portion 11a and the second extension portion 11b and the lattice portion 22. This stress stably locks the pallet band fastener 1 in the plurality of lattice holes 21, thereby further preventing the pallet band fastener 1 from falling out of the plurality of lattice holes 21.

[0031] The longitudinal lengths of the first protrusion 110a and the second protrusion 110b are each 0.1 mm or more, preferably 0.3 mm or more, and more preferably 0.5 mm or more, and are each 1.5 mm or less, preferably 1.2 mm or less, and more preferably 1 mm or less. Because the first protrusion portion 110a and the second protrusion portion 110b have the above-mentioned configuration, when the pallet band fastener 1 is attached to the pallet 2, stress is generated between the first extension portion 11a and the second extension portion 11b and the lattice portion 22, thereby preventing the pallet band fastener 1 from falling out of the multiple lattice holes 21 before the pallet band fastener 1 is engaged with the multiple lattice holes 21.

[0032] In the pallet band fastener 1' according to this embodiment, the first protrusion 110a may be composed of a plurality of protrusions, as shown in Fig. 4. That is, the first extension 11a may have one first protrusion 110a, or may have two or more first protrusions 110a. The number of first protrusions 110a is 1 to 5, preferably 1 to 4, and more preferably 1 to 3. In the pallet band fastener 1' according to this embodiment, the second protrusion 110b may be composed of a plurality of protrusions, as shown in Fig. 4. That is, the second extension 11b may have one second protrusion 110b, or may have two or more second protrusions 110b. The number of second protrusions 110b is 1 to 5, preferably 1 to 4, and more preferably 1 to 3. Within the above ranges, the number of the first protrusions 110a and the number of the second protrusions 110b are preferably two or more.

[0033] The height of each of the first protrusion 110a and the second protrusion 110b is preferably 1.0 mm or more, more preferably 1.5 mm or more, and is preferably 10.0 mm or less, more preferably 5.0 mm or less. The longer the lengths of the first protrusion 110a and the second protrusion 110b in the height direction are, the more preferable they are, as long as they are within the above ranges.

[0034] By configuring the number and height of the first protrusions 110a and the second protrusions 110b in the above manner, the contact area of ​​the first protrusions 110a and the second protrusions 110b with the lattice portion 22 increases when the pallet band fastener 1 is attached to the pallet 2. This increases the stress generated between the first extensions 11a and the second extensions 11b and the lattice portion 22, and the pallet band fastener 1 is more firmly engaged with the plurality of lattice holes 21. Because the first protrusion 110a and the second protrusion 110b have the above-mentioned configuration, when the pallet band fastener 1 is attached to the pallet 2, it is possible to further prevent the pallet band fastener 1 from falling out of the multiple lattice holes 21 before the pallet band fastener 1 is engaged with the multiple lattice holes 21.

[0035] 10, the width of the lower end of the lattice portion 22 in the height direction can be made wider than the remaining portion of the lattice portion 22. As a result, when the pallet band fastener 1 is attached to the pallet 2, the first protrusion 110a catches on the end, which further prevents the pallet band fastener 1 from falling out of the plurality of lattice holes 21 before the pallet band fastener 1 is locked into the plurality of lattice holes 21.

[0036] The present invention is not limited to the above-described embodiment.

[0037] The first region 101 and the second region 102 may have the same area or different areas, i.e., the area S1 of the first region 101 may be larger than the area S2 of the second region 102, the area S1 may be smaller than the area S2, or the area S1 and the area S2 may be the same.

[0038] The shape of the plate member 10 is not limited to a rectangle, but may be, for example, a trapezoid, a parallelogram, an ellipse, or the like.

[0039] The plate member 10 may be flat. The surface of the plate member 10 may have an uneven shape. The plate member 10 is preferably flat. [Explanation of symbols]
