Abstract
Description
Technical Field
[0001] This specification discloses a doorstrap that is installed on a flip-up tailgate. Background Technology
[0002] A design for a flip-up tailgate on the rear of the vehicle has been proposed for some time. The flip-up tailgate is positioned near its upper end and opens and closes by swinging around an axis parallel to the vehicle's width. Therefore, when the tailgate is open, it reaches almost to the height of the vehicle's roof. In this configuration, there is a problem that the tailgate may be difficult for the user to grasp and close.
[0003] Therefore, some solutions propose installing a downward-hanging strap on the tailgate. With the tailgate open, since the lower end of the strap is positioned lower than the tailgate itself, the user can easily grasp the strap compared to grabbing the tailgate. Then, by pulling on this strap, the tailgate can be closed. Summary of the Invention
[0004] To reduce the burden on users, it is desirable for the sling to be long enough. However, if the sling is too long, it may get caught in the tailgate when closing. While a dedicated component to prevent the sling from getting caught has been considered, this would lead to other problems such as increased costs.
[0005] Therefore, this specification discloses a door sling that can adequately ensure the length of the sling while preventing the sling from getting caught, and further suppresses costs.
[0006] Furthermore, although Japanese Patent Application Publication No. 2000-326729 discloses a technique for installing a strap on the tailgate, this strap is a strap that is pulled to be pressed, and even if it is relatively short, there is no problem. Therefore, Japanese Patent Application Publication No. 2000-326729 does not disclose any technique for preventing entrapment while lengthening the strap.
[0007] The door strap disclosed in this specification is a door strap installed on a flip-up tailgate. It is characterized by comprising: a strap body hanging from a fastening portion located on the cargo side of the tailgate; and a retaining portion extending from the fastening portion toward the lower end of the tailgate, which bends and connects to the middle position of the strap body, wherein the retaining portion bends the strap body at the middle position when the tailgate is closed. The retaining portion includes a first to a fifth flat rope, the first flat rope being bent into a U-shape and divided into a first portion extending from its bent portion toward the fastening portion, and a... From the bend towards the second part of the sling body, the second flat rope and the third flat rope have protective portions and extension portions. The protective portions are sewn together and onto the second part in a manner that wraps around the second part from both sides. The extension portions extend to the top of the bend in an extended state. The fourth flat rope is sewn onto the first part in a manner that overlaps with the first part, and its two ends are sewn onto the second flat rope and the third flat rope. The fifth flat rope is sewn across the second flat rope and the third flat rope in a manner that maintains the extended state of the extension portions.
[0008] According to the present invention, it is possible to ensure the length of the sling while preventing the sling from getting caught, and further, it is possible to control costs. Attached Figure Description
[0009] The features, advantages, and technical and industrial significance of exemplary embodiments of the present invention will now be described with reference to the accompanying drawings, wherein like symbols denote like elements, and wherein:
[0010] Figure 1 This is a 3D view of the car door sling.
[0011] Figure 2 This is a diagram illustrating the installation of door slings on the rear tailgate.
[0012] Figure 3 This is a schematic diagram illustrating the manufacturing process of the retaining part 14. Detailed Implementation
[0013] The structure of the door sling 10 installed on the rear tailgate 100 will be described below with reference to the accompanying drawings. Figure 1 A 3D view of the door sling 10. In addition, Figure 2 This is a schematic diagram illustrating the installation of the door hinge 10 on the rear tailgate 100. Additionally, in Figure 2 In this context, "Fr," "Up," and "Rh" represent the front of the vehicle, the top of the vehicle, and the right side of the vehicle, respectively. Additionally, Figure 2The upper part indicates that the tailgate 100 is open, and the lower part indicates that the tailgate 100 is closed.
[0014] First, a brief description of the tailgate 100. In this example, the tailgate 100 is a flip-up door located at the rear of the vehicle. The tailgate 100 is opened and closed by swinging around a hinge axis (not shown) located approximately parallel to the width of the vehicle and near the upper end of the tailgate 100. When open, the tailgate 100 is in a roughly horizontal position at approximately the same height as the vehicle roof; when closed, it is in a roughly vertical position.
[0015] Next, the door sling 10 will be explained. As... Figure 1 As shown, the door sling 10 includes a sling body 12, a retaining part 14, and a fastening bracket 16. The sling body 12 is a ring-shaped component hanging from the fastening bracket 16. The sling body 12 is constructed by folding a flat rope into a U-shape. The sling body 12 is divided into two parts by the folded part. Hereinafter, one of these two parts will be referred to as the outgoing part 12a, and the other as the returning part 12b.
[0016] To prevent the outgoing section 12a and the returning section 12b from touching each other, a spacer 20 is provided between them. The spacer 20 is constructed by bending a flat rope into a C-shape or a figure-9 shape, for example, and the two ends of the spacer 20 are connected to the outgoing section 12a and the returning section 12b.
[0017] The upper end of the sling body 12 is connected to the fastening bracket 16. The fastening bracket 16 is fastened to the side of the rear tailgate 100 by bolts or the like. The fastening bracket 16 is made of, for example, resin or metal.
[0018] The retaining part 14 is a portion that extends from the fastening bracket 16 toward the lower end of the tailgate 100, bends, and connects to the middle position of the sling body 12. This retaining part 14 has a certain degree of shape retention, allowing it to maintain a predetermined posture relative to the tailgate 100 even when the tailgate 100 is open or closed. Although in this example, the retaining part 14 is constructed by combining multiple flat ropes, this will be described later.
[0019] The door strap 10 described above is designed to facilitate closing the tailgate 100. In other words, when closing the open tailgate 100, the user needs to pull it downwards. However, as mentioned above, since the open tailgate 100 is approximately at the same height as the roof, depending on the user's size, it can sometimes be difficult to directly grasp the open tailgate 100.
[0020] On the other hand, when a door strap 10 is installed on the tailgate 100 as in this example, the user can simply grab the strap body 12 and pull it downwards to close the tailgate 100. Since the strap body 12 hangs down to a position low enough relative to the tailgate 100, even a shorter user can easily grab the strap body 12 and thus easily close the tailgate 100.
[0021] In order to reduce the burden on users, it is sought to make the sling body 12 long enough. However, if the sling body 12 is lengthened, the sling body 12 may be caught in the tailgate 100 when it is closed.
[0022] In this example, a retaining portion 14 is provided to prevent the sling body 12 from being clamped. As described above, the retaining portion 14 extends from the fastening bracket 16 toward the lower end of the tailgate 100, then bends and connects to the middle position of the sling body 12. In other words, a portion of the retaining portion 14 protrudes obliquely upward toward the upper end of the tailgate 100 as it moves away from the tailgate 100. By providing the retaining portion 14, when the tailgate 100 is closed, as... Figure 2 As shown in the lower half, the sling body 12 is bent in the middle. This prevents the lower end of the sling body 12 from becoming too low, thereby effectively preventing the sling body 12 from being caught in the tailgate 100.
[0023] Here, the retaining part 14 needs to maintain its shape to a degree that prevents its posture from changing under the influence of gravity. To ensure this shape retention, it is considered to construct part or all of the retaining part 14 using a rigid material such as resin. However, using a different raw material than the sling body 12 would lead to other problems such as increased costs or complicated manufacturing processes. Therefore, in this example, the retaining part 14 is constructed by combining multiple flat ropes of the same type as the sling body 12. This will be explained below.
[0024] Figure 3 This is a schematic diagram illustrating the manufacturing process of the retaining part 14. The retaining part 14 is constructed by combining the first to fifth flat ropes 22, 24, 26, 28, and 30. The first flat rope 22 is a flat rope that is bent into a "く" shape. The first flat rope 22 is divided into a first part 34 extending from its bent portion 32 toward the fastening bracket 16, and a second part 36 extending from the fastening bracket 16 toward the sling body 12.
[0025] The second flat rope 24 and the third flat rope 26 are flat ropes of roughly the same shape. For example... Figure 3As shown in state S12, the second flat rope 24 and the third flat rope 26 are arranged with their long sides roughly parallel to the long side of the second part 36. In the following text, the end of the second flat rope 24 and the third flat rope 26 that is closer to the sling body 12 in the long side direction is referred to as the "base end", and the end that is farther away from the sling body 12 is referred to as the "top end".
[0026] As shown in state S12, the second flat cord 24 overlaps the second part 36 in the thickness direction with its left end overlapping the right end of the second part 36. Furthermore, at this time, the second flat cord 24 is positioned such that its tip protrudes outward compared to the tip of the second part 36. In this state, the left end and base periphery of the second flat cord 24 are sewn together with the second part 36. Figure 3 The dashed lines in the diagram represent seams.
[0027] Similarly, the third flat cord 26 overlaps with the second part 36 in the thickness direction by overlapping its right end with the left end of the second part 36. Furthermore, in this state, the right end and base periphery of the third flat cord 26 are sewn together with the second part 36.
[0028] Next, as shown in state S14, the base periphery of the second flat rope 24 and the base periphery of the third flat rope 26 are bent in a manner close to each other and in a manner that wraps around the second part 36 from both sides. Then, the right end of the second flat rope 24 and the left end of the third flat rope 26 are sewn together in the closed state.
[0029] In the following text, the portion of the second flat rope 24 and the third flat rope 26 that covers the second part 36 is referred to as the "protective part 38". Furthermore, since the top periphery of the second flat rope 24 and the top periphery of the third flat rope 26 are not bent and expanded, they are referred to as the "expansion part 40".
[0030] If the protective section 38 can be formed, then the fourth flat rope 28 is sewn onto the first section 34, the second flat rope 24, and the third flat rope 26. Specifically, as follows... Figure 3 As shown in state S14, the fourth flat rope 28 is overlapped on the first part 34 with its long side direction orthogonal to the long side direction of the first part 34. In this state, the two ends of the long side direction of the fourth flat rope 28 are sewn onto the extensions 40 of the second flat rope 24 and the third flat rope 26. In addition, the fourth flat rope 28 is also sewn onto the first part 34.
[0031] Furthermore, such as Figure 3As shown in states S12 and S14, the fifth flat rope 30 is bent into two folds in the direction of its short side. Then, the top ends of the second flat rope 24 and the third flat rope 26 are clamped by the fifth flat rope 30, which is folded into two parts, and in this state, the fifth flat rope 30 is sewn onto the second flat rope 24 and the third flat rope 26.
[0032] In this way, by wrapping the second part 36 with the second flat rope 24 and the third flat rope 26, the rigidity around the second part 36 is improved, and the shape retention of the second part 36 is also improved. Furthermore, after arranging the fourth flat rope 28 and the fifth flat rope 30 orthogonally relative to the second flat rope 24 and the third flat rope 26, and sewing them onto the second flat rope 24, the third flat rope 26, and the first part 34, the retaining part 14 as a whole is less likely to fall laterally. As a result, the shape retention of the retaining part 14 is improved. Moreover, since the first to fifth flat ropes 22, 24, 26, 28, and 30 are made of the same type of flat rope as the sling body 12, cost increases are prevented.
