Description

[Technical field]

[0001] The present invention relates to a connecting and fixing structure for connecting and fixing a cargo collapse prevention net to a cargo bed such as a pallet, a dolly, or a truck via a cord-like member. [Background technology]

[0002] Cargo collapse prevention nets are used to prevent cargo from collapsing when it is placed on the platform of a pallet, cart, truck, etc. This cargo collapse prevention net is generally rectangular in shape and is used by placing the net over the cargo.

[0003] The cargo collapse prevention net in Patent Document 1 (Utility Model Registration No. 3135124) has a metal rope threaded along the periphery of the net. The weight of this metal rope prevents the net from shifting. In addition, a net adjustment rope is wrapped around the cargo to make the net tightly fit the cargo.

[0004] On the other hand, Patent Document 2 (Utility Model Registration No. 3122341) discloses a cargo shift prevention device that covers cargo with a sheet-like member instead of a cargo shift prevention net. This cargo shift prevention device has four corners of the sheet-like member connected and fixed to a pallet via fastening belts. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Utility Model Registration No. 3135124 [Patent Document 2] Utility Model Registration No. 3122341 Summary of the Invention [Problem to be solved by the invention]

[0006] Conventional cargo collapse prevention nets and cargo collapse prevention devices have the problem that the cargo securing force is insufficient. Increasing the number of securing points to increase the securing force increases the number of man-hours, making the work longer and reducing workability. Conversely, reducing the number of securing points to improve workability results in insufficient securing force.

[0007] The cargo collapse prevention net in Patent Document 1 is held down by the weight of the metal rope at the periphery of the net, and is not connected to the pallet, so there is a risk of cargo collapse. The cargo collapse prevention device in Patent Document 2 requires the shape of the sheet-like member to correspond to each cargo, so it is not versatile enough to accommodate various cargo shapes (height, size, etc.).

[0008] SUMMARY OF THE PRESENT EMBODIMENT An object of the present invention is to provide a connecting and fixing structure for a cargo collapse prevention net which can provide sufficient securing force for cargo even with a reduced number of securing points. [Means for solving the problem]

[0009] In order to solve the above-mentioned problems, the connecting and fixing structure of the present invention is a connecting and fixing structure for a cargo collapse prevention net, which connects and fixes a cargo collapse prevention net that is placed over a cargo placed on a loading platform such as a pallet, cart or truck to the loading platform of the pallet, cart or truck via a rope-like body, and is characterized in that the rope-like body forms a lasso-shaped loop and the lasso-shaped loop is inserted along the edge of the peripheral corner of the cargo collapse prevention net. Effect of the Invention

[0010] According to the connecting and fixing structure of the cargo collapse prevention net of the present invention, sufficient securing force for the cargo can be obtained even if the number of securing points is reduced. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] Hereinafter, a bogie according to each embodiment of the present invention will be described with reference to the drawings. Note that the same or corresponding parts are designated by the same reference numerals throughout the drawings, and duplicated explanations will be omitted as appropriate.

[0013] 1 is a perspective view showing a state in which a cargo collapse prevention net 10 is connected to a pallet P by a connecting and fixing structure according to an embodiment of the present invention. The cargo collapse prevention net 10 is usually rectangular in shape as shown in FIG.

[0014] However, depending on the shape of the cargo C, the cargo shift prevention net 10 may be triangular or strip-shaped. It is desirable for the cargo shift prevention net 10 to have elasticity in order to increase versatility for cargo shapes (one size can accommodate multiple sizes of cargo), but elasticity is not necessarily required.

[0015] 1 and 2, cord-like bodies 20 having a connecting and fixing structure according to an embodiment of the present invention are attached to the four corners of the load-shift prevention net 10. The cord-like bodies 20 are for connecting the four corners of the load-shift prevention net 10 to the pallet P. As the cord-like bodies 20, for example, ropes or belts can be used.

[0016] A load-tightening cord holder 30 is attached to the pallet side end of the cord 20 as shown in Fig. 3. The load-tightening cord holder 30 may be, for example, a rope holder as described in Japanese Patent Application No. 2024-123382.

[0017] The main body of the cargo-tie rope holder 30 is engaged with the pallet-side hook by a carabiner 40. The tip of the rope 20 pulled out from the cargo-tie rope holder 30 is connected to the longitudinal center of each side of the cargo-collapse prevention net 10 by a carabiner 50.

[0018] The other end of the cord-like body 20 is connected to the four corners of the load-shift prevention net 10. More specifically, a lasso-shaped loop 21 is formed at the other end of the cord-like body 20, and this lasso-shaped loop 21 is inserted alternately from the front to the back of the mesh of the net along the edges of the peripheral corners 11 of the load-shift prevention net 10 at the four corners.

[0019] In Fig. 4, the lasso-shaped loops 21 are inserted alternately through three meshes on each side along the two perpendicular sides of the peripheral corner 11. The number of meshes through which the lasso-shaped loops 21 are inserted alternately on the front and back can be appropriately increased or decreased according to the shape of the cargo, etc.

[0020] The load-shaking prevention net 10 is connected to the pallet as shown in Figures 5(a), (b), and (c). Figure 5(a) shows the state in which the carabiner 50 at one end of the rope 20 pulled out from the rope holder 30 for securing the load is being held by hand.

[0021] This carabiner 50 is engaged with the net-side hook 60 as shown in Fig. 5(b). The cord-like body 20 on the opposite side (right side) is similarly engaged with the net-side hook 60 as shown in Fig. 5(c).

[0022] The two rear cords 20 in Figure 5(c) are also engaged with the net hooks 60 in the same manner. This allows the four corners (four locations) of the load-shift prevention net 10 to be connected to the pallet P while being pulled tight by the lasso-shaped loops 21 of the cords 20.

[0023] 6(a) and (b) are diagrams for explaining the tightening action of the net 10 by the lasso-shaped loop 21. As shown in Fig. 6(a) and (b), the lasso-shaped loop 21 shrinks due to the force pulling one end of the cord-like body 20 toward the front, so that the peripheral corner 11 of the net 10 is tightened in a purse-like manner from three directions.

[0024] In particular, since the tightening action can be obtained in two horizontal directions, it is possible to tighten the girth of the cargo C. By tightening the girth, versatility for different sizes of cargo C can be improved.

[0025] Therefore, although only the four corners (four locations) of the cargo collapse prevention net 10 are connected to the pallet P with the cord-like bodies 20, a sufficient securing force for the cargo C can be obtained. This reduces the number of steps, shortening the work time and improving workability. In this way, the connecting and fixing structure according to the embodiment of the present invention is highly versatile for the size of the cargo C, so that one size can accommodate various shapes (heights, sizes, etc.) of cargo, as shown in Figures 7(a)-(d), for example.

[0026] Modified embodiment In the above embodiment, the rope 20 is fastened using the rope holder 30, but as shown in Figures 8 to 10, the rope 20 may be folded back with buckles 34 attached to the four corners of the pallet P by carabiners 35 without using the rope holder 30, and the carabiner 50 at the folded back end may be engaged with an appropriate position on the net side as shown in Figures 11(a) to (f). When using the buckle 34, it is preferable to use a belt as the rope 20.

[0027] A hoop 22 is formed at the end of the cord-like body 20 opposite the buckle 34 and carabiner 50, and the buckle 34 is passed through this hoop 22 to form a lasso-like loop 21. It is also possible to connect the folded end to the net-side hook by a suitable method such as a padlock knot without using the carabiner 50.

[0028] ●Tightening action of the net 12(c) and (d) show a conventional net connection and fixing structure that does not tighten the net with a lasso-shaped loop. In this case, the circumference of the load-fall prevention net 10 hardly shrinks, so it is difficult to apply effective tension to the net.

[0029] In contrast, the net connecting and fixing structure according to the embodiment of the present invention can tighten the four corners of the net 10 as shown in Fig. 12(a), thereby reducing the perimeter of the net 10 and applying effective tension to the net 10, thereby obtaining sufficient holding force for the cargo C. Therefore, when multiple cargoes C of different sizes are bulk loaded as shown in Fig. 12(b), the cargoes C can be stably held even if the cargo shape is very uneven.

[0030] Summary Although the embodiment of the present invention has been described above, the present invention is not limited to the above embodiment and can be modified in various ways. For example, instead of inserting the lasso-shaped loops 21 alternately through the meshes of the net from the front to the back, they may be inserted through multiple rings attached along the edges of the peripheral corners 11 of the net 10.
