Description

Technical Field

[0001] This invention relates to a tarpaulin and container assembly, and more particularly to a tarpaulin and container assembly that is easy to secure. Background Technology

[0002] An open-top container is a type of container with a completely open top and no roof. To protect against wind, rain, and theft, a tarpaulin can be added to the top of an open-top container. If a tarpaulin is to be added to an open-top container, corresponding tarpaulin locking loops must be installed around the container body to secure the tarpaulin. To ensure the loops do not exceed the width of the container, they are typically installed within recesses in the container's side walls. For the tarpaulin's edge buckles to engage with the locking loops, the tarpaulin must be spread out along the corrugated shape of the container's side walls. However, existing tarpaulin edges are usually flat, making it impossible to achieve this side-wall corrugation, thus making it difficult to secure the tarpaulin to the locking loops.

[0003] In view of this, it is necessary to improve the existing tarpaulins and container components to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a tarpaulin and container assembly that is easy to fix.

[0005] To achieve the above-mentioned objectives, the present invention provides a container assembly, including an open-top container and a tarpaulin, wherein the tarpaulin has a main body and a fixing structure connected around the main body, wherein the fixing structure includes a plurality of fixing units arranged sequentially along the edge of the main body, and each fixing unit has at least one first holding structure formed thereon.

[0006] The main body of the tarpaulin is used to cover the top of the open-top container. The open-top container has side walls, and the outer side of the side walls has recessed portions spaced apart and a second holding structure protruding into the recessed portions. The tarpaulin is fixed to the second holding structure by the first holding structure of the fixing unit.

[0007] The fixing structure further includes a telescopic unit that connects two adjacent fixing units. The width of the telescopic unit gradually increases from the main body to the edge of the main body. The telescopic unit allows at least one end of two adjacent fixing units away from the main body to move away from or towards each other. As a further improvement of the invention, the fixing unit is rectangular or inverted trapezoidal.

[0008] As a further improvement of the present invention, the telescopic unit is a connecting material that can be folded or unfolded, and its top is connected to the main body.

[0009] As a further improvement of the present invention, the distance between two adjacent first holding structures does not exceed 200mm.

[0010] As a further improvement of the present invention, the sidewall includes a plurality of bottom plates forming the recesses, side plates located on both sides of the bottom plates, and an outer plate connecting the side plates between adjacent recesses, wherein the second holding structure is disposed on the bottom plates and / or the side plates.

[0011] As a further improvement of the present invention, the tarpaulin is provided with at least one of the fixing units corresponding to each recess, which respectively cooperate with the second fixing structure on the side plate and / or the bottom plate.

[0012] As a further improvement of the present invention, the fixing unit and the recess are provided in a one-to-one correspondence, and each fixing unit has at least two first fixing structures that cooperate with the second fixing structure respectively.

[0013] As a further improvement of the present invention, the maximum width of the telescopic unit when unfolded is not less than the width of the outer plate.

[0014] As a further improvement of the present invention, the first retaining structure and the second retaining structure are a buckle and a locking ring that cooperate with each other.

[0015] The beneficial effects of this invention are as follows: The fixing structure of the tarpaulin and container assembly of this invention includes a plurality of fixing units arranged sequentially along the edge of the main body, and each fixing unit has at least one first holding structure formed thereon. Therefore, the fixing units can be inserted into the recesses of the container sidewall and fixed to the container, thereby improving the fixing effect between the tarpaulin and the container, thus improving the wind and rain protection effect and ensuring the quality of the goods.

[0025] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the scope of protection of the present invention.

[0026] Please refer to Figures 1 to 9 The illustration shows an embodiment of the tarpaulin of the present invention. The tarpaulin 1 has a main body 11 and a fixing structure 12 connected around the main body 11. The fixing structure 12 includes a plurality of fixing units 13 arranged sequentially along the edge of the main body 11. Each fixing unit 13 has at least one first holding structure 14 formed on it.

[0027] In this embodiment, the tarpaulin 1 is applied to a container; therefore, the present invention also provides a container assembly. Of course, the tarpaulin 1 can also be applied to other equipment that requires covering.

[0028] The container assembly includes an open-top container 2 and a tarpaulin 1. The main body 11 of the tarpaulin 1 is used to cover the top of the open-top container 2. The open-top container 2 has a side wall 21. The side wall 21 has recesses 22 spaced apart on its outer side and a second holding structure 23 protruding into the recesses 22. The tarpaulin 1 is fixed to the second holding structure 23 by a first holding structure 14 of a fixing unit 13.

[0029] like Figure 2 and Figure 3 As shown, the open-top container 2 has four side walls 21, each side wall 21 having spaced-apart recesses 22. Each side wall 21 includes a base plate forming the recesses 22, side plates located on both sides of the base plate, and an outer plate connecting the side plates between adjacent recesses 22. The second holding structure 23 is disposed on the base plate and / or the side plate.

[0030] Because the four corners 24 of the open-top container 2 are slightly higher than the upper ends of the side walls 21. In this embodiment, each of the side walls is a corrugated plate, the bottom plate is a concave corrugated plate 25, the outer plate is a convex corrugated plate 26, the side plate is a sloping plate 27 connecting the concave corrugated plate 25 and the convex corrugated plate 26, the recess 22 is formed between the sloping plate 27 and the concave corrugated plate 25, and the second holding structure 23 is disposed on the sloping plate 27.

[0031] The four corners of the tarpaulin 1 have clearance spaces 15 that cooperate with the corner portions 24, so that the fixing structures 12 on the four sides of the tarpaulin 1 can be fixed to the side walls 21, preventing the tarpaulin 1 from sticking up and improving the windproof and rainproof effect.

[0032] The tarpaulin 1 is provided with at least one fixing unit 13 corresponding to each recess 22, which respectively cooperates with the second holding structure 23 on the side plate and / or the bottom plate. In this embodiment, each fixing unit 13 of the tarpaulin 1 has a first holding structure 14, and the tarpaulin 1 is provided with two fixing units 13 corresponding to each recess 22, which respectively cooperate with the second holding structure 23 on the inclined plate 27. This ensures that there are a considerable number of first holding structures 14 and second holding structures 23, thereby ensuring the fixing effect. Moreover, the fixing unit 13 enters the recess 22 and cooperates with the second holding structure 23, and is not likely to protrude beyond the plane where the corrugated plate 26 is located, thereby reducing the risk that the first holding structure 14 and the second holding structure 23 of the tarpaulin 1 will exceed the plane where the corrugated plate 26 is located after being fixed, thus meeting the TIR requirements.

[0033] Furthermore, the two adjacent fixing units 13 are spaced apart, meaning there is a certain gap between the two adjacent fixing units 13. In other words, the width of each fixing unit 13 is relatively small, thereby further reducing the risk of the fixing unit 13 exceeding the plane of the convex plate 26. At the same time, the two adjacent fixing units 13 are not constrained, making it easier for them to enter the recess 22.

[0034] Of course, in other embodiments, the fixing unit 13 of each fixing structure 12 can also be provided in a one-to-one correspondence with the recess 22 of each side wall 21, and two first holding structures 14 are provided on each fixing unit 13, that is, the fixing unit 13 is provided relatively wider.

[0035] Alternatively, when the density of the recessed portion 22 is high, the second holding structure 23 can also be disposed on the concave corrugated plate 25. In this case, the first holding structure 14 of each fixing unit 13 and the second holding structure 23 on each concave corrugated plate 25 can cooperate to achieve a better fixing effect. Furthermore, the distance between the second holding structure 23 and the plane where the convex corrugated plate 26 is located is greater, that is, the second holding structure 23 can be disposed further inward, thereby further reducing the risk of the first holding structure 14 and the second holding structure 23 of the tarpaulin 1 extending beyond the plane where the convex corrugated plate 26 is located after fixing.

[0036] like Figure 4 and Figure 5As shown, the fixing unit 13 can be rectangular, trapezoidal, or other shapes, thereby reducing the risk of the fixing unit 13 protruding from the plane of the corrugated plate 26. The distance between two adjacent first fixing structures 14 does not exceed 200mm, thereby ensuring that there are a sufficient number of first fixing structures 14 for the tarpaulin 1, and thus ensuring the fixing effect between the tarpaulin 1 and the open-top container 2.

[0037] like Figure 6 and Figure 7 As shown, the present invention also provides another tarpaulin structure, wherein the fixing structure 12 further includes a telescopic unit 16 connected between two adjacent fixing units 13, the telescopic unit 16 being able to move at least one end of the two adjacent fixing units 13 away from the main body 11 away from each other or move closer to each other.

[0038] The telescopic unit 16 is a foldable or unfoldable connecting material that connects two adjacent fixed units 13. For example, the telescopic unit 16 can be made of the same material as the tarpaulin 1, or it can be made of other materials with good structural strength, or it can be made of materials with elastic deformation capabilities. When manufacturing the tarpaulin 1, the telescopic unit 16 can be fixed between the two fixed units 13 after the fixed units 13 are manufactured. Of course, if the telescopic unit 16 is made of the same material as the tarpaulin 1, the telescopic unit 16 can also be integrally formed with the fixed units 13, similar to a lace skirt.

[0039] In this embodiment, the telescopic unit 16 is preferably integrally formed with the tarpaulin 1, which not only simplifies manufacturing but also ensures better strength because the fixing unit 13 and the telescopic structure are integrated. Furthermore, the telescopic unit 16 can prevent rainwater from entering the open-top container 2 between two adjacent fixing units 13. The width of the telescopic unit 16 gradually increases from the main body 11 towards its edge, and the top of the telescopic unit 16 is connected to the main body 11.

[0040] On the one hand, reducing the material of the telescopic unit 16 reduces the production cost of the tarpaulin 1. On the other hand, since the telescopic unit 16, which is further away from the edge of the main body 11, is narrower, when the tarpaulin 1 is fixed to the open-top container 2, the telescopic unit 16, which is further away from the edge of the main body 11, fits more tightly with the corrugated plate 26. This not only increases the wind and rain protection effect, but also avoids the tarpaulin 1 protruding too much from the plane where the corrugated plate 26 is located, thus reducing the risk of damage to the tarpaulin 1.

[0041] The fixing unit 13 is provided in a one-to-one correspondence with the recess 22, and each fixing unit 13 has at least two first holding structures 14 that cooperate with the second holding structure 23. The maximum width of the telescopic unit 16 when unfolded is not less than the width of the outer plate, that is, the maximum width of the telescopic unit 16 when unfolded is not less than the width of the corrugated plate 26.

[0042] In this embodiment, each fixing unit 13 is provided with a pair of first holding structures 14, and the side wall 21 is provided with second holding structures 23 on both inclined plates 27 in each recess 22. Therefore, each recess 22 has two pairs of holding structures that are fixed to each other, which greatly improves the fixing effect of the tarpaulin 1. Of course, in other embodiments, the concave wave plate 25 may also be provided with second holding structures 23, and the fixing unit 13 has three first holding structures 14 to cooperate with the second holding structures 23 of the concave wave plate 25 and the inclined plate 27 respectively.

[0043] Of course, in other embodiments, when the density of the recessed portion 22 is large, the second holding structure 23 can also be disposed on the concave wave plate 25, and each fixing unit 13 can also be provided with only one first holding structure 14, which can also achieve a good fixing effect.

[0044] In this embodiment, the width of the telescopic unit 16 when unfolded is greater than the width of the corrugated plate 26, which facilitates the fixing unit 13 to enter the recess 22. On the one hand, this facilitates the fixing of the first holding structure 14 and the second holding structure 23. On the other hand, it also reduces the risk of the fixing unit 13 protruding from the plane where the corrugated plate 26 is located, thereby reducing the risk of damage to the tarpaulin 1.

[0045] In this embodiment, the first holding structure 14 and the second holding structure 23 are a buckle and a locking ring that cooperate with each other, so as to facilitate mutual fixation. Of course, other holding structures can also be used.

[0046] like Figure 8 and Figure 9 The present invention also provides another container component, which differs in that the side wall 21 of the open-top container 2 has a different structure. The side wall 21 includes a side wall body 28 and reinforcing beams 29 spaced apart on the outer surface of the side wall 21, with the recess 22 formed between two adjacent reinforcing beams 29.

[0047] The sidewall body 28 is a flat plate structure, and the reinforcing beam 29 is a rectangular tubular structure. In this container structure, the bottom plate is the sidewall body 28, the side plate is the sidewall of the reinforcing beam 29, and the outer plate is the outer wall of the reinforcing beam 29. The maximum width of the telescopic unit 16 when unfolded is not less than the width of the reinforcing beam 29, that is, the maximum width of the telescopic unit 16 when unfolded is not less than the width of the outer wall.

[0048] Furthermore, the tarpaulin 1 in both of the above embodiments is applicable to the sidewall 21 of this structure. Since the spacing between adjacent reinforcing beams 29 is relatively large, the second holding structure 23 is disposed on the sidewall body 28. Of course, in other embodiments, when the density of the reinforcing beams 29 is high, i.e., when the spacing between adjacent reinforcing beams 29 is small, the second holding structure 23 can also be disposed on the sidewall of the reinforcing beams 29.

[0049] In summary, the tarpaulin and container assembly of the present invention allow the fixing unit 13 to enter the recess 22 of the container side wall 21 and be fixed to the container, thereby improving the fixing effect between the tarpaulin 1 and the container, and further improving the effect of wind and rain protection, and ensuring the quality of goods.

[0050] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
