Description

[Technical Field]

[0001] The present invention relates to a waterproof sheet for a vehicle, for example, for protecting the vehicle from flooding or the like. [Background technology]

[0002] BACKGROUND ART In order to prevent parked vehicles from being flooded due to flood damage caused by heavy rain, typhoons, etc., there have been proposals to cover vehicles with waterproof sheets or the like (Patent Document 1, etc.). The vehicle waterproof sheet proposed in Patent Document 1 is configured such that the main body lower cloth 4 and the main body upper cloth 3 are joined at the bottom side, as shown in Figure 3 of Patent Document 1, and a slit 7 is provided in the main body upper cloth 3 to form the main body waterproof upper cloth middle part 5. As shown in Figure 3 of the same document 1, after placing the vehicle on the lower main body cloth 4, the upper main body cloth 5 is placed over the vehicle, and the waterproof fasteners 7 placed in the slits 7 of the upper main body cloth 3 are closed, thereby completely covering the vehicle. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2010-215210 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in Patent Document 1, the joint between the upper main body cloth 3 and the lower main body cloth 4 is located at a position corresponding to the bottom of the vehicle, which poses a problem in that there is a high possibility of water seeping in through this joint. In order to solve this problem, it is conceivable to position the joint on the upper side in the vehicle height direction. However, the lower main body cloth 4 needs to be made more rigid in order to place the vehicle thereon, and as a result, it is heavy. Therefore, if the joint is located at the upper side in the vehicle height direction, when the operator closes the waterproof fastener, etc., he or she will have to endure the weight of the heavy main body lower cloth 4 while operating it, and there is also the problem that it would be difficult to force the operator to perform such an action during heavy rain, etc.

[0005] Therefore, the present invention aims to provide a vehicle protective sheet, etc. that prevents water from entering through the joint between the lower sheet portion on which the vehicle is placed and the upper sheet portion that covers the vehicle, and also improves the operability of the operator who operates the waterproof fastener portion that connects the upper sheet portion and the lower sheet portion.

[0006] According to the present invention, the object is achieved by providing a vehicle seat having a lower sheet portion on which a vehicle is placed and an upper sheet portion that covers the vehicle, the upper sheet portion being formed thinner than the lower sheet portion, the lower sheet portion and the upper sheet portion having a lower sheet joint portion and an upper sheet joint portion for joining them, respectively, the lower sheet joint portion and the upper sheet joint portion being configured so that the lower sheet portion and the upper sheet portion are positioned in a middle portion in a height direction of the vehicle with the vehicle accommodated inside, and a cut portion is formed in the upper sheet portion and the cut portion is configured to be capable of being separated or joined. This is achieved by a waterproof sheet for a vehicle, characterized in that a waterproof fastener portion is formed which can be fastened to the vehicle from the starting portion to the ending portion, the waterproof fastener portion having an element portion arranged in the cutting portion and a slider portion which is operated by an operator to engage the element portions with each other, and having a starting portion which engages the element portions with each other and an ending portion which completes the engagement of the element portions, and the waterproof fastener portion is formed so as to gradually increase in height in the vehicle direction from the starting portion to the ending portion when the vehicle is accommodated inside the lower seat portion and the upper seat portion.

[0007] According to the above configuration, the lower sheet joint and the sheet joint are configured so that the lower sheet portion and the upper sheet portion are positioned in the middle part of the vehicle's height (door portion, etc.) when the vehicle is housed inside, so that even in the event of heavy rain, etc., water can be effectively prevented from seeping in through the lower sheet joint and the sheet joint.

[0008] Furthermore, when the vehicle is accommodated inside the lower seat section and the upper seat section, the waterproof fastener section is formed so that it gradually becomes higher in the height direction of the vehicle from the starting section to the terminal section. In other words, when the operator operates the slider part to engage the element parts with each other, the starting part where the element parts are in the most separated state is the most difficult to operate in the event of heavy rain, etc., so this starting part is placed at the lowest part and in a position that is easy for the operator to operate. As the element parts become more interlocked and the number of element parts in a separated state decreases, the position becomes higher, but because operability is gradually improved, even this higher position does not impose a heavy burden on the operator.

[0009] On the other hand, although waterproof fasteners are placed at the cutting section, making the connection waterproof, there is still a possibility of water intrusion, so it is desirable to place the section as high up in the vehicle's vertical direction as possible. In this regard, in the above configuration, the cutting portion is configured to gradually become higher from the starting portion to the terminal portion when in a connected state (when the element portions are interlocked), thereby further reducing the possibility of water intrusion, etc. Furthermore, the upper sheet portion is formed thinner than the lower sheet portion, which also makes it easier for the operator to operate the slider portion of the waterproof fastener portion.

[0010] Preferably, in the vehicle waterproof sheet, the lower sheet portion has a larger area than the upper sheet portion.

[0011] According to the above configuration, the lower seat portion is formed to have a larger area than the upper seat portion, so that when the lower seat portion and the upper seat portion are fitted with the vehicle inside, the lower seat joint portion and the upper seat joint portion can be reliably positioned at or above the middle part of the vehicle's height direction. This ensures that the vehicle is protected from flooding even in the event of heavy rain or other events that cause water to accumulate around the vehicle.

[0012] Preferably, the vehicle waterproof sheet is characterized in that the upper sheet joint portion is joined to the outside of the lower sheet joint portion.

[0013] According to the above configuration, the upper sheet joint is joined to the outside of the lower sheet joint, so that even in the event of heavy rain, the possibility of water entering the upper sheet portion and the lower sheet portion within the joint between the upper sheet joint and the lower sheet joint can be extremely reduced.

[0014] Preferably, in the vehicle waterproof sheet, the upper sheet joint portion and the lower sheet joint portion are respectively formed with small pieces for joining the upper sheet and small pieces for joining the lower sheet, and the small pieces for joining the upper sheet are configured to abut against the underside of the small pieces for joining the lower sheet.

[0015] According to the above configuration, the upper sheet joint piece abuts against the underside of the lower sheet joint piece, so that after they abut and join, the lower sheet joint piece is subjected to a force that moves it downward due to the weight of the lower sheet.However, since the upper sheet joint piece is positioned below the lower sheet joint piece, the joint between the two becomes stronger. Therefore, the bond between the upper sheet joint and the lower sheet joint is stronger, which reduces the possibility of flooding even in the event of heavy rain.

[0016] Preferably, the vehicle waterproof sheet is characterized in that the upper sheet portion and the lower sheet portion are respectively formed with upper sheet fixing devices and lower sheet fixing devices for positioning the upper sheet and lower sheet fixing devices.

[0017] According to the above configuration, the upper sheet and the lower sheet fixing device (rope, etc.) can be placed between the upper sheet fixing device (upper sheet engaging piece, etc.) and the lower sheet fixing device (lower sheet engaging piece, etc.), and can be moved in a direction narrowing the gap between the two. This makes it difficult for the upper and lower sheet portions covering the vehicle to deform unstably due to typhoon winds and the like, and makes them more stable. In particular, the lower seat portion is heavier than the upper seat portion and also acts as a weight (anchor) for supporting the vehicle, so the upper seat portion is positioned more stably by the lower seat portion via the upper seat and lower seat fixing devices. Furthermore, it is possible to reliably prevent objects such as gas cylinders mounted on the loading platform of the vehicle from falling off the loading platform. [Effects of the Invention]

[0018] As described above, the present invention has the advantage of being able to provide a vehicle protective sheet, etc. that prevents water from seeping in through the joint between the lower sheet portion on which the vehicle is placed and the upper sheet portion that covers the vehicle, and also improves the operability of the operator who operates the waterproof fastener portion that connects the upper sheet portion and the lower sheet portion.

[Figure 8] FIG. 10 is a schematic diagram showing a second modified example of the present embodiment. DETAILED DESCRIPTION OF THE INVENTION

[0020] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. The embodiments described below are preferred examples of the present invention, and therefore various technically preferable limitations are applied. However, the scope of the present invention is not limited to these embodiments unless otherwise specified in the following description to the effect that the present invention is specifically limited.

[0021] (Main components of vehicle protection sheet 1) FIG. 1(1) is a schematic diagram showing the main configuration of the lower sheet 100 of the vehicle waterproof sheet 1 according to an embodiment of the present invention, and (2) is a schematic diagram showing the main configuration of the upper sheet 10. As shown in Figures 1(1) and 1(2), the vehicle waterproof sheet 1 has an upper sheet portion, e.g., an upper sheet 10, which is approximately rectangular overall, and a lower sheet portion, e.g., a lower sheet 100, which is the same size as the upper sheet 10, and forms an approximately rectangular shape with a width w of 3.6 m and a length l of 5.4 m in Figure 1.

[0022] In addition, as shown in Figure 1(2), the upper sheet 10 has upper sheet joints 11a, 11b, 11c, and 11d formed on each of its four sides, and as shown in Figure 1(1), the lower sheet 100 also has lower sheet joints 101a, 101b, 101c, and 101d formed on each of its four sides. The upper sheet 10 and the lower sheet 100 are integrated together by welding the upper sheet joints 11a etc. and the lower sheet joints 101a etc. to each other.

[0023] (Upper sheet joint 11a, etc. and lower sheet joint 101a, etc.) The upper sheet joints 11a, etc. and the lower sheet joints 101a, etc. are joined to each other by welding or the like, specifically, the upper sheet joints 11a, etc. are positioned outside the lower sheet joints 101a, etc. and are welded or the like, joined, and integrated. By arranging them in this manner, it is possible to effectively prevent water from entering the lower sheet joint portion 101a from above, even during heavy rain.

[0024] (Weight of upper sheet 10 and lower sheet 100, etc.) The upper sheet 10 is made of a synthetic resin sheet such as polyethylene, and weighs, for example, about 3 kg (#3000). On the other hand, the lower sheet 100 is made of the same synthetic resin sheet such as polyethylene as the upper sheet 10, but its weight is, for example, 4 kg (#4000), making it heavier and more sturdy than the upper sheet 10.

[0025] Specifically, the thickness of the lower sheet 100 is, for example, 0.34 mm, which is thicker than the thickness of the upper sheet 10, for example, 0.25 mm. This is because heavy vehicles (delivery vehicles such as trucks carrying gas cylinders, etc., and bulk vehicles such as bulk lorries) are placed directly on the lower sheet 100, so it is made thick and is configured to make it easy to place heavy vehicles on it.

[0026] Here, a bulk truck is a type of tank truck that delivers and fills LP gas, etc. A bulk truck has a tank that stores LP gas, etc., and is equipped with a motor for discharging the LP gas, etc. from this tank. This motor is positioned at a height of, for example, about 60 cm above the road surface where the tires land. 1(1), the lower seat 100 also displays a vehicle stopping position (a mark indicating the stopping position of the front wheels) P. Specifically, this is the stopping position P of the front wheels of the vehicle.

[0027] (Opening and closing parts and waterproof zippers, etc.) As shown in Figure 1 (2), the upper sheet 10 has an opening / closing section 12 that can be opened and closed, and a cutting section 13, which is the cut portion of this opening / closing section 12 with the upper sheet 10, has a waterproof fastener 14 (an example of a waterproof fastener section) that can cut or join the cutting section 13. Therefore, by operating the waterproof fastener 14, the cutting portion 13 can be cut and the opening / closing portion 12 can be opened, and the cutting portion 13 can also be put into a non-cutting state and the opening / closing portion 12 that is in an open state can be put into a closed state.

[0028] Specifically, the waterproof fastener 14 includes element parts formed in the cutting section 13, such as an opening / closing section side element 14a and an upper sheet side element 14b, and a slider 14c (an example of a slider part) that connects (interlocks) the opening / closing section side element 14a and the upper sheet side element 14b to each other.

[0029] This slider 14c is configured to move between two starting points 13a, 13a in Figure 1, where the opening / closing section side element 14a and the upper sheet side element 14b are separated and the opening / closing section 12 is in a completely open state, to two ending points 13b, 13b in Figure 1, where the opening / closing section side element 14a and the upper sheet side element 14b are connected and the opening / closing section 12 is in a completely closed state.

[0030] Specifically, when the sliders 14c, 14c move from the starting portions 13a, 13a toward the terminal portions 13b, 13b, the movement of the slider 14c causes the opening / closing portion side element 14a and the upper sheet side element 14b to connect with each other, and the opening / closing portion 12 becomes closed (the cutting portion 13 is in a non-cutting state), and conversely, when the sliders 14c, 14c move from the terminal portions 13b, 13b toward the starting portions 14c, 14c, the movement of the slider 14c causes the opening / closing portion side element 14a and the upper sheet side element 14b to move away from each other, and the opening / closing portion 12 becomes open (the cutting portion 13 is in a cutting state).

[0031] In addition, the starting portions 13a, 13a of the sliders 14c, 14c are located on the base side of the opening / closing portion 12, as shown in Figure 1 (2), and the two terminal portions 13b, 13b are formed on the free end side, which is the tip side of the opening / closing portion 12. Also, as shown in Figure 1 (2), the cutting portion 13 (waterproof fastener 14) of the opening / closing portion 12 is formed so that the opening / closing portion 12 gradually narrows from the two starting portions 13a, 13a on the base side to the terminal portions 13b, 13b on the free end portion.

[0032] (Upper sheet engaging pieces 15a, etc. and lower sheet engaging pieces 105a, etc.) As shown in FIG. 1(2), the upper sheet 10 is formed with, for example, nine upper sheet engaging pieces 15a to 15i, which are upper sheet fixing members. As shown in FIG. 1(1), the lower sheet 100 is formed with, for example, eight lower sheet engaging pieces 105a to 105i, which are lower sheet fixing members. These upper sheet engaging pieces 15a, etc. and lower sheet engaging pieces 105a, etc. are, for example, in the shape of a deformable ring, and are configured so that they can be tied with upper sheet and lower sheet fixing devices such as ropes.

[0033] (Method of using the vehicle protection sheet 1 according to the present embodiment) For example, the method of using the vehicle protection sheet 1 for a vehicle, such as a delivery truck 50, during heavy rain caused by a typhoon or the like will be described below.

[0034] (preparation process) FIG. 2 is a schematic explanatory diagram showing a state in which the opening and closing portion of the upper seat is in the open state and the delivery vehicle 50 is positioned. First, as shown in FIG. 2, the vehicle protection sheet 1 shown in FIGS. 1(1) and 1(2) is placed in a location where the delivery vehicle 50 can be safely parked. At this time, the lower sheet 100 is positioned on the ground side, and the upper sheet 10 is positioned on the upper side.

[0035] At this time, the opening / closing portion 12 of the upper sheet 10 is in the closed state, so the sliders 14c, 14c of the upper sheet 10 are positioned at the end portions 13b, 13ba. Then, the user operates the sliders 14c, 14c to move the sliders 14c, 14c from the terminal ends 13b, 13b to the starting ends 13a, 13a, thereby putting the opening / closing section 12 into the open state. Then, the openable / closable unit 12 is opened and placed in the state shown by the broken line in FIG.

[0036] (Process of placing delivery vehicle 50) Next, the delivery vehicle 50 is driven in the direction of arrow F in FIG. 2, that is, from right to left in FIG. 2, and the delivery vehicle 50 is stopped so that the front wheels 51a, 51b of the delivery vehicle 50 are placed on the stopping position P.

[0037] (Step of covering the delivery vehicle 50 with the upper sheet 10) Next, the user places the opening / closing unit 12 over the delivery vehicle 50 so as to cover the delivery vehicle 50. At this time, the operator holds a reacher (a type of tool used to grab or pull something that is out of reach), such as a magic wand, and engages and operates the tip of the reacher with the upper sheet engagement pieces 15a to 15i formed on the upper side of the opening / closing unit 12 in Figure 2, thereby making it easier to move the opening / closing unit 12. For example, the opening / closing unit 12 can be easily placed on the delivery vehicle 50 by gripping the upper sheet engaging piece 15i with a magic hand.

[0038] (Operation of opening / closing section 12, etc.) Next, the user grasps one slider 14c located at the starting section 13a in Fig. 2 and moves the slider 14c toward the terminal section 13b, and then similarly moves the other slider 14c toward the terminal section 13b.

[0039] FIG. 3 is a schematic explanatory view showing a state in which the slider 14c has been moved to the terminal end portion 13b. As shown in FIG. 3, the delivery vehicle 50 is completely covered with the vehicle protection sheet 1. As shown in FIG. 3, the waterproof fastener 14 (cutting portion 13) is disposed obliquely from the starting portion 13a to the terminal portion 13b.

[0040] Specifically, the positions of the delivery vehicle 50 are arranged so that the positions gradually increase in the height direction from the departure point 13a to the terminal point 13b. This is because, as shown in FIG. 1, the opening / closing section 12 is formed so that its width gradually narrows from the base side toward the tip end (free end, terminal end) side. In this way, if the starting portion 13a is low and the ending portion 13c is high, it becomes easier for the user to operate the slider 14c of the waterproof fastener 14. In other words, when the waterproof fastener 14 of the opening / closing section 12 is in a fully open state (the opening / closing section side element 14a and the upper sheet side element 14b are not connected (engaged) with each other at all), the user will have to exert a large amount of force to move the slider 14c. In particular, since the protective sheet 1 for vehicles according to this embodiment is intended to be used during heavy rain such as a typhoon, the user is likely to have difficulty operating the slider 14c.

[0041] Therefore, in this embodiment, the position of the slider 14c is set low at the starting section 13a where the user requires the most force, and is set higher as the slider 14c advances and the closing state of the opening / closing section 12 progresses. The reason why the waterproof fasteners 14 (cutting portions 13) are arranged gradually higher is as follows.

[0042] That is, although the waterproof fastener 14 has high waterproofing properties, it is possible that water may accumulate around the delivery vehicle 50 in a heavy rain or the like, and water may seep in through the waterproof fastener 14. Therefore, it is important to position the waterproof fastener 14 as high as possible, but if it is positioned this high, there is a problem that it becomes difficult for the user to operate. Therefore, in this embodiment, in order to avoid the risk of water intrusion as much as possible without impairing the operability of the operator, the waterproof fastener 14 (cutting portion 13) is configured to gradually increase in height from the starting portion 13a to the terminal portion 13c.

[0043] The waterproof fastener 14 is arranged on the thin upper sheet 10, thereby improving the operability of the slider 14c for the user. On the other hand, the lower sheet 100 is formed thicker than the upper sheet 10, making it easier to place delivery vehicles 50 and the like.

[0044] In this embodiment, the inclination of the waterproof fastener 14 (the inclination with respect to an imaginary line parallel to the ground) is preferably, for example, 1° to 4°. This is because the beginning of work is the most difficult part, so the optimum height for a worker of average height working in a standing position at a distance of 20cm from the fastener is 110cm to 120cm. For this reason, at the start of work, this height should be used, and a gradient of 2 degrees or more for the water flow on the fastener will ensure sufficient flow rate. Also, in the case of bulk trucks, it is preferable to position the water supply above the apex of the R (radius) of the rear tank shape due to the characteristics of the vehicle.

[0045] Also, as shown in Figure 3, the joint where the upper sheet joint 11a etc. and the lower sheet joint 101a etc. are joined to each other by welding or the like is configured to be located not on the bottom side of the delivery vehicle 50, but in the middle part in the height direction of the delivery vehicle 50 (for example, the door part, etc.).

[0046] Furthermore, as described above, at the joints where the upper sheet joints 11a, etc. and the lower sheet joints 101a, etc. are joined to each other by welding, the upper sheet joints 11a, etc. are positioned outside the lower sheet joints 101a, etc., so the risk of flooding is low. However, it is conceivable that water may accumulate around the delivery vehicle 50 in the event of heavy rain, etc., and the water level may rise up to this joint. Therefore, in this embodiment, this joint is positioned high up to the middle part of the height of the delivery vehicle 50 (for example, the door part, etc.), which makes it possible to better avoid the risk of flooding due to heavy rain, etc.

[0047] (Using the upper sheet engaging piece 15a, etc., the lower sheet engaging piece 105a, etc.) When the delivery vehicle 50 is covered with the vehicle protection sheet 1, the upper sheet 10 and the lower sheet 100 may flap about due to wind and rain during a typhoon or the like, which may cause gas cylinders and the like mounted on the bed of the delivery vehicle 50 to fall over. Therefore, in this embodiment, the upper sheet 10 and the lower sheet 100 are fixed together using the upper sheet engaging pieces 15a and the like and the lower sheet engaging pieces 105a and the like.

[0048] FIG. 4 is a schematic explanatory diagram showing a state in which the upper sheet 10 and the like are fixed by the upper sheet engaging pieces 15a and the like. As shown in Figure 4, in the vehicle protective sheet 1 that accommodates a delivery truck 50 inside, as described above, upper sheet engagement pieces 15a, 15b, 15c, 15d, 15e, 15f, 15g, 15h, and 15i are formed on the upper sheet 10, and lower sheet engagement pieces 105a, 105b, 105c, 105d, 105e, 105f, 105g, and 105h are formed on the lower sheet 100.

[0049] In this embodiment, as shown in Figure 4, the upper sheet engaging pieces 15h, 15g, 15f, 15e, 15i are tied to the corresponding lower sheet engaging pieces 105g, 105f, 105e, 105d, 105h with ropes R4, R3, R2, R1, R5 (examples of upper sheet and lower sheet fixing devices), and by moving and tightening the tied upper sheet engaging pieces 15h etc. and lower sheet engaging pieces 105g etc. in a direction narrowing the gap, the vehicle protective sheet 1 is brought into closer contact with the transport vehicle 50.

[0050] This makes it difficult for the upper sheet 10 and the lower sheet 100 covering the transport vehicle 50 to deform unstably due to typhoon winds and the like, and makes them stable. In particular, as described above, the lower sheet 100 is heavier than the upper sheet 10, and furthermore, when the transport vehicle 50 is placed on it, it acts as a weight (anchor), so that the upper sheet 10 is more stably positioned by the lower sheet 100 via rope R4, etc. Furthermore, it is possible to reliably prevent objects such as gas cylinders mounted on the loading platform of the transport vehicle 50 from falling off the loading platform.

[0051] The opposite side of the vehicle protective sheet 1 shown in Figure 4 is similarly fixed with ropes, and is configured so that the upper sheet engagement pieces 15a, 15b, 15c, and 15d are fixed to the corresponding lower sheet engagement pieces 105g, 105f, 105e, and 105d via ropes. Of the above, the upper sheet engaging piece 15i and the lower sheet engaging piece 105h correspond to the rear side of the transporter 50, and the others correspond to the side sides.

[0052] As shown in FIG. 4, the upper sheet engaging pieces 15h, 15f may be connected to anchors AN1, AN2 such as steel frames placed on the ground by ropes R6, R7. In this case, the transporter 50 is fixed more stably. Similarly, the upper sheet engaging pieces 15a, 15c on the opposite side may be connected to an anchor with a rope.

[0053] FIG. 5 is a schematic view showing the left side of FIG. 5 is a schematic diagram showing the front side of a transport vehicle 50 with the protective sheet 1 for vehicles covering the transport vehicle 50. As shown in FIG. As shown in Figure 5, the front side of the transport vehicle 50 is configured such that, for example, two upper sheet engaging pieces 15d, 15e are connected and fixed to one lower sheet engaging piece 105d with ropes R1, R8, thereby bringing the upper sheet 10 and the lower sheet 100 into closer contact with the transport vehicle 50.

[0054] By using the vehicle protection sheet 1 on the transport vehicle 50 as described above, the user can quickly and easily protect the transport vehicle 50 from dangers such as flooding, even during heavy rain such as a typhoon, and can also safely protect the transport vehicle 50 from winds such as typhoons.

[0055] Furthermore, when removing the vehicle protection sheet 1 from the transport vehicle 50, the transport vehicle 50 can be made movable simply by removing the rope R1, etc., operating the slider 14c of the waterproof fastener 14, and opening the opening / closing section 12, making it extremely quick and easy to operate.

[0056] (When the vehicle is a heavy bulk truck or other bulk vehicle) FIG. 6 is a schematic explanatory diagram showing the state in which the vehicle protection sheet 1 is applied to the bulk vehicle 500 described above. As shown in Figure 6, as described above, the bulk vehicle 500 has a "motor 501" located on the underside of its body, at a height of, for example, about 60 cm above the road surface on which the tires land. For this reason, the motor is prone to malfunction if it is submerged in water.

[0057] In this regard, the joint where the upper sheet joint 11a, etc. and the lower sheet joint 101a, etc. of the upper sheet 10 of the vehicle protective sheet 1 in this embodiment are welded together is located in a part of the bulk vehicle 500 that is higher in the height direction than the part where the motor 501 is located, for example, near the door. This configuration effectively prevents water from entering the motor. Furthermore, the waterproof fasteners 14 formed on the upper sheet 10 are located at a higher position than the joints, so the risk of water seeping in through the waterproof fasteners 14 can also be avoided.

[0058] (First Modification of the Present Embodiment) FIG. 7 is a schematic diagram showing a first modified example of the present embodiment. The main configuration of the first modification of this embodiment is similar to that of the above-described embodiment, and therefore the following description will focus on the differences. In this modification, unlike the above-described embodiment, the area of ​​the lower sheet 1000 is larger than the area of ​​the upper sheet 200. Therefore, as shown in Figure 7, the position of the joint where the upper sheet joint 211a etc. and the lower sheet joint 1101a etc. are welded together is formed at a higher position H in the height direction of the transport vehicle 50, unlike Figure 3 of the above-mentioned present embodiment. Therefore, even if water accumulates around the vehicle protection sheet 2 due to heavy rain or the like, the risk of flooding or the like can be more effectively avoided.

[0059] (Second Modification of the Present Embodiment) FIG. 8 is a schematic diagram showing a second modified example of this embodiment. The main configuration of the second modification of this embodiment is similar to that of the above-described embodiment, and therefore the following description will focus on the differences. In this modification, the configurations of the upper sheet joint portions 11a etc. and the lower sheet joint portions 101a etc. are different from those of the above-described embodiment. Specifically, as shown in FIG. 8, in this modification, the configuration of upper sheet joint portions 311a etc. of the upper sheet 300 and the configuration of lower sheet joint portions 3001a etc. of the lower sheet 3000 are different.

[0060] That is, upper sheet joining pieces 311aa etc. and lower sheet joining pieces 3001aa etc. are formed on the upper sheet joining portions 311a etc. and the lower sheet joining portions 3001aa etc., respectively, as shown in FIG. When the upper sheet joint portions 311a etc. and the lower sheet joint portions 3001a etc. are joined together, the upper sheet joint portion small pieces 311aa etc. come into contact with the underside of the lower sheet joint portion small pieces 3001aa etc. and are joined together. By configuring it in this manner, after the upper sheet 300 and the lower sheet 3000 are joined, the lower sheet joint pieces 3001aa, etc. are subjected to a force by the heavy lower sheet 3000, which moves them downward (in the direction of arrow Dn in Figure 8).However, at that time, since the upper sheet joint pieces 311aa, etc. are arranged below the lower sheet joint pieces 3001aa, etc., the joint between the two becomes stronger. In this way, the joint between the upper sheet 300 and the lower sheet 3000 is more firmly joined, which reduces the possibility of flooding even in the event of heavy rain.

[0061] The above describes the embodiments of the present invention. However, the present invention is not limited to the above embodiments, and various modifications can be made without departing from the scope of the claims. The configurations of the above embodiments can be partially omitted or arbitrarily combined in a different manner from the above. [Explanation of symbols]
