Description

Technical Field

[0001] This invention belongs to the field of logistics and transportation equipment, and specifically relates to a folding container. Background Technology

[0002] Goods currently stored and transported in metal cages, such as cigarettes, processed beef and mutton, and potted flowers, are susceptible to damage due to their large size, weight, and susceptibility to crushing and impacts. Furthermore, the volume and weight of these storage units necessitate the installation of casters at the bottom of the containers to aid movement and reduce the labor intensity of operators during handling. However, these large, movable metal containers are typically assembled from bent and welded metal pipes and wires. The high density of metal components, coupled with the fact that only metal materials can be welded together, results in heavy storage containers that are difficult to handle and move after loading. This leads to time-consuming, labor-intensive, and inefficient warehousing and transfer processes (pushing from the warehouse into the container).

[0003] Secondly, since the main body and side panels of this type of metal container are mostly made of metal steel pipes and mesh-like metal panels, the unit mass is large. In particular, in order to maximize the container loading rate, this type of metal container is often designed to meet the maximum internal height of the container (usually about 2.3 meters). Such metal cages with a large height are heavy, have a high center of gravity, are difficult to move, and have the safety hazard of collapsing during the movement.

[0004] In addition, metal containers like these are typically transported via shipping containers, vans, or small vans during transit. However, these containers often have a fixed height, which limits their loading capacity when transported in different vans (with varying internal heights). This necessitates handling and transferring containers, significantly reducing container turnover efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a foldable container to solve the above-mentioned problems. To this end, the technical solution adopted by this invention is as follows:

[0006] A collapsible container, wherein the collapsible container comprises:

[0007] Chassis vehicles; and

[0008] At least one collapsible enclosure, wherein, in an unfolded state, the collapsible enclosure is detachably mounted on the chassis vehicle to form a container, and the collapsible enclosure is configured such that one of the collapsible enclosures is detachably mounted on another collapsible enclosure to achieve container height adjustment.

[0009] In one embodiment, the foldable panel box includes:

[0010] A pair of first side plates are detachably mounted on the left and right sides of the chassis vehicle, respectively;

[0011] A pair of door panels, each hinged to the front end of a pair of first side panels and capable of closing with each other; and

[0012] A pair of second side plates hinged to each other, the pair of second side plates being respectively hinged to the rear ends of a pair of first side plates.

[0013] In one embodiment, a first locking mechanism is provided between the chassis and the first side plate, and between the upper and lower first side plates.

[0014] In one embodiment, the first locking mechanism includes a limiting structure disposed on the upper surface of the chassis or the first side plate and a mechanical lock mounted on the first side plate, wherein the mechanical lock cooperates with the limiting structure to achieve locking.

[0015] In one embodiment, the limiting structure is a groove, which is disposed on the inner end face of the limiting protrusion of the chassis or the first side plate. The mechanical lock includes a bolt and a reset member. The bolt is slidably mounted on the first side plate and has an operating part and a bolt limiting part. The operating part can operably drive the bolt limiting part away from the groove to unlock. One end of the reset member is connected to the first side plate and the other end is connected to the bolt. The reset member's reset action causes the bolt limiting part to enter the groove to lock.

[0016] In one embodiment, the foldable enclosure box is configured such that the folded foldable enclosure box can be accommodated in the unfolded state of the foldable enclosure box.

[0017] In one embodiment, the hinge structure between the door panel and the first side panel is the same as the hinge structure between the second side panel and the first side panel.

[0018] In one embodiment, the hinge structure includes a plurality of first protrusions spaced vertically on the end face of the first side plate, a plurality of second protrusions spaced vertically on the end face of the L-shaped end of the door panel or the second side plate, and a first hinge shaft. The first protrusions and the second protrusions are complementary to each other and each has a first hinge hole extending vertically. The first hinge shaft passes through the first hinge hole.

[0019] In one embodiment, at least one second locking mechanism is provided between a pair of door panels.

[0020] In one embodiment, the second locking mechanism includes a handle seat, a handle, and a second reset member. The handle seat is rotatably mounted on the end face of one of the door panels away from the first side panel. The handle is slidably mounted on the handle seat and has a first handle limiting portion. The first handle limiting portion cooperates with a first door panel limiting portion of the other door panel to achieve locking. One end of the second reset member abuts against the handle seat, and the other end abuts against the handle.

[0021] In one embodiment, the second reset member is an arc-shaped elastic sheet, the arc apex of which is fixedly installed on the handle and its two ends abut against the handle seat.

[0022] In one embodiment, the arc-shaped elastic sheet has two spaced-apart first T-shaped protrusions at the apex of the arc, and the handle has a second T-shaped protrusion, which is engaged between the two first T-shaped protrusions.

[0023] In one embodiment, the handle seat includes a central square groove portion and handle seat mounting portions at both ends. The second reset member is installed in the square groove portion. The end of the handle seat mounting portion is provided with a second hinge hole. The door panel is provided with a third hinge hole aligned with the second hinge hole. The handle seat is hinged to the door panel by the hinge shaft passing through the second hinge hole and the third hinge hole. The handle seat mounting portion has a through groove, and the side wall of the through groove is provided with a sliding groove extending in the left-right direction. The handle includes a panel and a handle mounting portion and a first handle limiting portion extending downward from the lower surface of both sides of the panel. The panel is provided with a concave operating portion. The first handle limiting portion protrudes from the handle mounting portion. The handle limiting portion and the handle mounting portion are both received in the through groove. The side of the handle mounting portion is provided with a slide bar that slides with the sliding groove.

[0024] In one embodiment, the cross-section of the first handle limiting portion is triangular, and correspondingly, the first door panel limiting portion is a V-shaped groove.

[0025] In one embodiment, the handle further has a second handle limiting portion, which cooperates with a second door panel limiting portion on the door panel on which the handle seat is mounted. During the movement of the handle in the opening direction, the second handle limiting portion disengages before the first handle limiting portion.

[0026] In one embodiment, the upper and lower end faces of the first side plate and the second side plate are provided with complementary limiting grooves and limiting protrusions, so that the foldable enclosure box can be stacked vertically.

[0027] In one embodiment, the chassis vehicle is provided with a limiting groove for receiving the limiting protrusion.

[0028] In one embodiment, the first side plate is fixedly installed with a horizontally extending reinforcing tube below the limiting groove and limiting protrusion at the upper end and above the limiting groove and limiting protrusion at the lower end, respectively.

[0029] In one embodiment, the first side panel, the second side panel, and the door panel are all integrally formed perforated panels.

[0030] In one embodiment, the upper surface of the chassis vehicle is provided with a groove for receiving the rollers of the chassis vehicle, so that multiple chassis vehicles can be stacked. Preferably, the groove is an arc-shaped groove, and its depth is 50-80% of the radius of the roller.

[0031] The present invention adopts the above-mentioned solution, which has the following advantages: the height of the foldable container of the present invention is adjustable, making it easier to fold and recycle, and improving storage and transportation efficiency. Attached Figure Description

[0051] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to provide a clearer understanding of the purpose, features, and advantages of the present invention. It should be understood that the embodiments shown in the drawings are not intended to limit the scope of the present invention, but are merely illustrative of the essential spirit of the technical solution of the present invention.

[0052] In the following description, certain specific details are set forth for the purpose of illustrating various disclosed embodiments in order to provide a thorough understanding of the various disclosed embodiments. However, those skilled in the art will recognize that embodiments may be practiced without one or more of these specific details. In other instances, well-known apparatuses, structures, and techniques associated with this application may not have been shown or described in detail to avoid unnecessarily obscuring the description of the embodiments.

[0053] Unless the context requires otherwise, throughout the specification and claims, the word “comprising” and its variations, such as “including” and “having”, shall be understood to have an open, inclusive meaning, that is, to be interpreted as “including, but not limited to”.

[0054] Throughout this specification, references to "an embodiment" or "an embodiment" indicate that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. Therefore, the appearance of "in an embodiment" or "an embodiment" in various places throughout the specification does not necessarily refer to the same embodiment. Furthermore, a particular feature, structure, or characteristic may be combined in any manner in one or more embodiments.

[0055] The singular forms “a” and “the” used in this specification and the appended claims include plural references unless otherwise expressly stated herein. It should be noted that the term “or” is generally used to mean “and / or” unless otherwise expressly stated herein.

[0056] In the following description, in order to clearly demonstrate the structure and working method of the present invention, a number of directional terms will be used. However, terms such as "front", "back", "left", "right", "outside", "inside", "outward", "inward", "up", and "down" should be understood as convenient terms and not as limiting terms.

[0057] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0058] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0059] For ease of description, the side containing the door panel 22 of the folding container 100 will be referred to as the front side. For example... Figure 1-18 As shown, the foldable container 100 of the present invention includes:

[0060] Chassis vehicle 1; and

[0061] At least one foldable side panel box 2, wherein, in the unfolded state, the foldable side panel box 2 is detachably mounted on the chassis vehicle 1 to form a container, and the foldable side panel box 2 is configured such that one foldable side panel box 2 (i.e., upper side panel box 2b) is detachably mounted on another foldable side panel box 2 (lower side panel box 2a) (see [reference]). Figure 17 This allows for adjustable container height.

[0062] Since the chassis 1 and the collapsible crate 2 are separable, they can be stored and transported separately, and the crate is foldable, which is very convenient. At the same time, the collapsible crate 2 is usually injection molded from plastic, greatly reducing its weight. Furthermore, the stacking quantity of the collapsible crates can be selected according to different transport vehicle specifications, achieving adjustable container height and greatly improving applicability without the need for crate swapping. The height of the collapsible crate can be one or more specifications. For example, the height of the collapsible crate can be selected between 0.5m and 2m, such as 0.5m, 1m, or 2m.

[0063] During installation, unfold the foldable side panel box 2, align it with the limiting structure on the chassis vehicle 1, and press it down to complete the installation. It is very convenient. To disassemble, simply loosen the corresponding locking mechanism. The chassis vehicle 1, the foldable side panel box 2, and the fixing structure between them are described in detail below.

[0064] like Figure 2 and 19As shown, the chassis 1 includes a chassis 11 and four wheels 12 fixedly mounted on the bottom of the chassis 11. The wheels 12 facilitate the movement of the folding container 100. The wheels 12 can be omnidirectional wheels with brakes. The chassis 11 is generally square with rounded corners. The chassis 11 can be injection molded from a lightweight material such as plastic or rubber. The chassis 11 has a certain thickness (e.g., more than 5 cm) to provide sufficient support. The upper surface of the chassis 11 has four grooves 111 for receiving the wheels 12, allowing the chassis 1 to be stacked on top of each other (see [reference]). Figure 19 This design reduces the space occupied, thus facilitating the storage and transportation of the chassis vehicle 1. Preferably, the groove 111 is an arc-shaped groove, with a depth of 50-80% of the radius of the roller 12.

[0065] Four limiting protrusions 112 are provided on the upper surface of the chassis 11 near the corners. These limiting protrusions 112 are received in corresponding recesses at the bottom of the foldable panel box 2 during installation. The limiting protrusions 112 are generally rectangular, with a height typically between 2 and 5 cm. A groove 1121 is provided on the inner end face of the limiting protrusion 112. This groove 1121 is used to engage with the locking tongue of the locking mechanism 3 installed on the bottom of the foldable panel box 2 (described in detail below) to fix the foldable panel box 2 to the chassis 1. The portion of the inner end face of the limiting protrusion 112 above the groove 1121 has a guide slope to guide the locking tongue of the locking mechanism 3.

[0066] The upper surface of the chassis 11 is also provided with four elongated limiting grooves 113, which are used to cooperate with the limiting protrusions on the bottom of the foldable side panel box 2 to further limit the foldable side panel box 2 on the chassis vehicle 1.

[0067] like Figures 2-18 As shown, the foldable panel box 2 includes:

[0068] A pair of first side plates (or long side plates) 21 are detachably mounted on the left and right sides of the chassis vehicle 1, respectively.

[0069] A pair of door panels 22, each hinged to the front end of a pair of first side panels 21 and capable of closing with each other; and

[0070] A pair of second side plates (or short side plates) 23 are hinged to each other, and the pair of second side plates 23 are respectively hinged to the rear end of a pair of first side plates 21.

[0071] When folding, first fold the pair of door panels 22 and the pair of second side panels 23 inward (e.g., Figure 3 (As shown), then press the pair of first side panels 21 against each other, so that the pair of door panels 22 and the pair of second side panels 23 are completely folded between the pair of first side panels 21 (as shown). Figure 4 (As shown). The folded thickness is basically equal to the thickness of two door panels (second side panels) plus the thickness of two first side panels, taking up very little space. When unfolded, simply pull the pair of first side panels 21 outwards until the pair of door panels 22 and the pair of short side panels 23 are fully unfolded.

[0072] The first side panel 21, the door panel 22, and the second side panel 23 can be integrally injection molded from lightweight materials such as plastic or rubber. To further reduce weight, the first side panel 21, the door panel 22, and the second side panel 23 can adopt a hollow structure. In this embodiment, the hollow structure is an array of circular rectangular holes.

[0073] In this embodiment, the foldable enclosure box 2 adopts a double-door structure (i.e., has a pair of door panels) for easy folding. It should be understood that the foldable enclosure box 2 can also be a single-door structure.

[0074] The locking mechanism 3 between the chassis 1 and the first side panel 21 of the foldable side panel box 2 is described below. In this embodiment, as... Figure 16 As shown, the locking mechanism 3 includes a latch 31 and a reset member 32. The latch 31 is slidably mounted on the first side plate 21 and has an operating part 311 and a latch limiting part 312. The operating part 311 operably drives the latch limiting part 312 away from the groove 1121 on the chassis 1 to achieve unlocking. That is, the user can operate the unlocking through the operating part 311. One end of the reset member 32 is connected to the first side plate 21, and the other end is connected to the latch 31. The reset action of the reset member 32 causes the latch limiting part 312 to enter the groove 1121 to achieve locking. In this embodiment, the reset member 32 is a spring. When the foldable side panel box 2 is installed on the chassis vehicle 1, the locking tongue 31 moves in the unlocking direction under the action of the limiting protrusion 112 on the chassis 11, and the spring 32 is compressed. When the locking tongue limiting part 312 moves to the aligned groove 1121, under the reset action of the spring 32, the locking tongue limiting part 312 inserts into the groove 1121, thus locking. To unlock, the locking tongue 31 is moved in the unlocking direction by the operating part 311, causing the locking tongue limiting part 312 to disengage from the groove 1121. In this embodiment, the operating part 311 is a rectangular recess for easy hand operation and a simple appearance. Preferably, an unlocking direction arrow is marked on the bottom of the operating part 311. It should be understood that the operating part 311 can also be other structural shapes, such as a handle or a round handle.

[0075] Preferably, the locking mechanism 3 can also be used for locking between the upper and lower foldable side panel boxes 2. That is, the upper surface of the first side panel 21 is also provided with a limiting protrusion 211 having the same structure as the limiting protrusion 112 of the chassis vehicle 1, such as... Figure 2 and 17 As shown.

[0076] It should be understood that the locking mechanism between the chassis vehicle 1 and the foldable side panel box 2 is not limited to the above structure. For example, a structure with a pin and a pin hole can also be used, or a fastening structure can also be used.

[0077] To facilitate the installation between the upper and lower foldable enclosure boxes 2, complementary limiting grooves 212 and 231 and limiting protrusions 213 and 232 are provided on the upper and lower end faces of the first side plate 21 and the second side plate 23. That is, taking the first side plate 21 as an example, the limiting groove 212 and limiting protrusion 213 at the lower end of the first side plate 21 of the upper enclosure box 2 are respectively complementary to the limiting protrusion 213 and limiting groove 212 at the upper end of the lower enclosure box 2.

[0078] Furthermore, to enhance the strength of the first side plate 21, horizontally extending reinforcing tubes 24 are fixedly installed on the first side plate 21 below the upper limiting groove 212 and limiting protrusion 213, and above the lower limiting groove 212 and limiting protrusion 213, respectively. Figure 6 As shown. The reinforcing tube 24 can be embedded in the first side plate 1 during the integral molding process, or it can be fixedly installed in the reinforcing tube mounting cavity 214 of the first side plate 21 during the subsequent installation of the foldable enclosure box 2.

[0079] Preferably, the foldable box 2 is configured such that the folded foldable box 2 can be upright and placed inside the container 100 (i.e., upright inside the foldable box 2 in its unfolded state), such as Figure 18 As shown. That is to say, the outer width of the foldable panel box 2 after folding is smaller than the inner width of the container 100.

[0080] In this embodiment, the hinge structure between the door panel 22 and the first side panel 21 is the same as the hinge structure between the second side panel 23 and the first side panel 21. Specifically, the hinge structure between the door panel 22 and the first side panel 21 will be used as an example for explanation. Figure 4 and 5 As shown, the hinge structure includes a plurality of first protrusions 215 spaced vertically on the end face of the first side plate 21, a plurality of second protrusions 221 spaced vertically on the end face of the L-shaped end 220 of the door panel 22, and a hinge shaft 25. The first protrusions 215 and the second protrusions 221 are complementary to each other. That is, one first protrusion 215 engages between two second protrusions 221, and one second protrusion 221 engages between two first protrusions 215. Both the first protrusions 215 and the second protrusions 221 have hinge holes extending vertically, and the hinge shaft 25 passes through the hinge holes, thereby hinged the first side plate 21 to the door panel 22. The first protrusions 215 and the second protrusions 221 can be the same size or different sizes. The number of first protrusions 215 and the second protrusions 221 is related to their vertical dimensions and the height of the container 100.

[0081] Preferably, the height of the L-shaped end of the door panel 22 is substantially equal to the thickness of the first side panel 21, and the height of the first protrusion of the first side panel 21 is substantially equal to the thickness of the door panel 22 (specifically, the L-shaped end). Therefore, it can be ensured that the outer width of the foldable collapsible box 2 after folding is less than the inner width of the container 100, so that the foldable collapsible box 2 can be upright and placed into the container 100, which is convenient for storage and transportation.

[0082] In this embodiment, two second locking mechanisms 4 are provided between a pair of door panels 22, one above the other. It should be understood that the number of second locking mechanisms 4 is not limited to the embodiment shown. Specifically, as... Figure 7-10 As shown, the second locking mechanism 4 may include a handle base 41, a handle 42, and a second reset member 43. The handle base 41 and handle 42 can also be injection molded from plastic or the like. The handle base 41 is rotatably mounted on the end face (e.g., the left end) of one of the door panels 22 (e.g., the right door panel 22b) away from the first side panel 21. The handle 42 is slidably mounted on the handle base 41 and has a first handle limiting portion 421, which engages with a first door panel limiting portion 222 of the other door panel 22 (e.g., the left door panel 22a) to achieve locking. One end of the second reset member 42 abuts against the handle base 41, and the other end abuts against the handle 42. To open the door, the locking mechanism 4 must first be unlocked. Unlocking is achieved by moving the handle 42 in the unlocking direction (i.e., to the left), causing the first handle limiting portion 421 to disengage from the first door panel limiting portion 222. When handle 42 is released, handle 42 automatically resets under the action of reset component 43.

[0083] In this embodiment, the second reset member 43 is an arc-shaped elastic sheet, with its arc apex fixedly mounted to the handle 42 and its two ends abutting against the handle seat 41. Specifically, the arc apex of the arc-shaped elastic sheet has two spaced-apart first T-shaped protrusions 431, and the handle 42 has a second T-shaped protrusion 422, which engages between the two first T-shaped protrusions 431, thereby fixing the arc apex (i.e., the right end) of the arc-shaped elastic sheet to the handle 42. The two ends (i.e., the left end) of the arc-shaped elastic sheet 43 are cylindrical, that is, their cross-section is circular. Preferably, the handle seat 41 has a limiting recess (not shown) to restrict the two ends of the arc-shaped elastic sheet 43 within it. It should be understood that the second reset member 43 can also be a spring or other form of elastic reset member.

[0084] In this embodiment, the handle base 41 is approximately U-shaped, including a square groove portion 411 in the middle and handle base mounting portions 412 at both ends. The square groove portion 411 has an opening on the left side. The second reset member 43 is installed in the square groove portion 411, that is, the second T-shaped protrusion 422 of the handle 42 is located in the square groove portion 411. The end of the handle base mounting portion 412 protrudes from the square groove portion 411, that is, it is wider than the square groove portion 411, and is provided with a first hinge hole 413. The door panel 22 is provided with a second hinge hole 223 aligned with the first hinge hole 413. The handle base 41 is hinged to the door panel 22 by the hinge shaft 26 passing through the first hinge hole 413 and the second hinge hole 223. Therefore, the locking mechanism 4 can rotate relative to the door panel 22 (e.g., 0 to 180°), so that a pair of door panels 22 can be folded inward. The handle seat mounting portion 412 has a through groove 414, and the side wall of the through groove 414 is provided with a sliding groove 4141 extending in the left-right direction. The handle 42 includes a panel 423 and a handle mounting portion 424 and a first handle limiting portion 421 extending downward from the lower surfaces on both sides of the panel 423. The panel 423 covers the handle seat 41. The panel 423 is provided with a concave operating portion 425, the size of which is set to accommodate at least two fingers side by side for easy operation. It should be understood that the structure of the operating portion of the handle 42 is not limited to the embodiment shown. In this embodiment, the panel 423 of the handle 42 is also provided with an arrow mark for indicating the unlocking direction, the arrow mark being located to the left of the concave operating portion 425. The first handle limiting portion 421 protrudes from the handle mounting portion 424, that is, the lower end of the handle mounting portion 424 is lower than the lower end of the handle limiting portion 421. Both the handle limiting part 424 and the handle mounting part 424 are received in the through groove 414 of the handle seat mounting part 412. The side of the handle mounting part 424 is provided with a slide bar 4241 that slidably engages with the slide groove 4141. Therefore, when the handle 42 is installed on the handle seat 41, the handle 42 can slide left and right, thereby unlocking and resetting locking.

[0085] In this embodiment, the cross-section of the first handle limiting portion 421 is triangular, and correspondingly, the first door panel limiting portion 222 is a V-shaped groove (e.g., opening to the left). The first handle limiting portion 421 can slide into the first door panel limiting portion 222 from left to right or slide out of the first door panel limiting portion 222 from right to left. It should be understood that the shape and structure of the first handle limiting portion 421 and the first door panel limiting portion 222 are not limited to the embodiment shown.

[0086] In this embodiment, the handle 42 also has a second handle limiting portion 426, which cooperates with a second door panel limiting portion 224 on the door panel 22 (i.e., the right door panel 22b) on which the handle seat 41 is mounted, to restrict the locking mechanism 4 from rotating relative to the door panel 22. During the movement of the handle 42 in the opening direction (unlocking direction), the second handle limiting portion 426 disengages before the first handle limiting portion 421. The cross-section of the second handle limiting portion 426 is approximately L-shaped, and its outer surface is a slope. The second door panel limiting portion 224 is located outside (on the left side) of the second hinge hole 223 of the door panel 22.

[0087] When the foldable panel box 2 is in the use (expanded) state, the second handle limiting part 426 of the second locking mechanism 4's handle 42 engages with the second door panel limiting part 224 of the door panel 22, such as Figure 10 As shown; when folding the foldable panel box 2, move the handle 42 to the left a certain distance to disengage the second handle limiting part 426 from the second door panel limiting part 224, as shown. Figure 11 As shown, the left door panel can rotate relative to the right door panel at this time; when the door panel 22 of the foldable enclosure box 2 is to be opened, the handle 42 is moved to the left to the maximum extent (i.e., the maximum distance), so that the first handle limiting part 421 is disengaged from the first door panel limiting part 222, as shown. Figure 12 As shown, the second locking mechanism 4 can then be rotated toward the right door panel and attached to it, as shown. Figure 13 As shown; at this point, door panel 22 can be opened outwards, as... Figure 14 As shown.

[0088] The chassis 1 and the foldable side panel box 2 of the foldable container 100 of the present invention can be disassembled and stored separately. At the same time, the foldable side panel box 2 can be stacked, which is very convenient to use and can be applied to various transport vehicles.

[0089] The preferred embodiments of the present invention have been described in detail above. However, it should be understood that after reading the above teachings, those skilled in the art can make various alterations or modifications to the present invention. These equivalent forms also fall within the scope defined by the appended claims.
