Description

[Detailed Description of the Invention] << Field of the Invention >> This invention relates to a vehicle equipped with a retractable back door,
The present invention relates to a cover structure in which a back door is removed and a back door opening is covered with canvas or the like.

<< Prior Art and its Problems >> Generally, a thin metal plate is mainly used as a constituent member of a vehicle body. The thin metal plate is satisfactory in terms of rigidity, but has a drawback that it is heavy.

Recently, there has been a demand for improving the appearance performance of passenger cars and reducing the weight of the vehicle body, and there is a tendency that a thin metal plate as a constituent member of the vehicle body is replaced with a lightweight reinforced plastic plate or the like.

By the way, when comparing the functions of each part of the constituent members of the passenger car, the roof and the back door portion of the vehicle do not require so much rigidity as compared with other portions, and for example, the roof portion is replaced with a sunroof such as tempered glass. There is.

Therefore, the inventor uses a conventional metal thin plate in combination with a cover body that is lightweight and has an excellent external appearance for a vehicle model that includes an openable backdoor, such as a hatchback vehicle. We focused on reducing weight and diversifying designs.

<Purpose of Invention> The present invention has been made based on the above-mentioned points of view. The purpose of the present invention is to provide a back door opening which can greatly contribute to diversification of vehicle designs and weight reduction of vehicles. It is to provide a cover structure.

<< Structure and Effect of the Invention >> In order to achieve the above object, the present invention is a cover structure in a back door opening in which a back door opening formed by removing a back door from a vehicle body is covered with a cover body, wherein the cover body comprises: A frame bent to have substantially the same shape as the opening edge, and the edge is wound around and fixed to the frame;
It consists of a canvas stretched inside this frame, and the frame is configured to be foldable via a hinge part, and when the cover body is attached to the vehicle body side, the frame is covered with the hinge part so that the expanded shape of the frame. It is characterized in that the collar holding the is slidably inserted into the frame.

That is, according to the above configuration, as a cover body that covers the opening formed by removing the back door from the vehicle body, the cover body includes a frame having substantially the same shape as the peripheral edge of the opening and a canvas supported by the frame. because there is,
Compared with the conventional back door made of a thin metal plate, it is possible to achieve a large weight reduction, and the back door and the cover body can be arbitrarily used, so that the design can be diversified.

Further, since the cover body according to the present application has a hinge portion provided on the frame and is configured to be foldable around this hinge portion, for example, when the cover body is not used, the cover body is folded and stored compactly in a trunk room. When attaching this cover to the opening with the back door removed, the frame is expanded and the hinge is covered with a collar to prevent rattling due to vehicle vibration and the like. It is highly practical because it can prevent the car body or canvas from being damaged by the edges of the.

<< Description of Embodiments >> Hereinafter, one embodiment of a cover structure according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is an overall perspective view showing a state in which a cover body used in the present invention is attached to a vehicle body, FIGS. 2 to 3 are sectional views showing the configuration of the cover body used in the present invention, and FIG. 4 is the present invention. FIG. 5 and FIG. 6 are perspective views showing a frame of the cover body according to FIG.

In FIG. 1, a cover body 1 used in the present application is installed in an opening 2 formed by removing a back door (not shown) from a vehicle body, and a pipe material is bent into a shape substantially the same as the peripheral shape of the opening 2. The frame 3 is substantially composed of a frame 3 and a canvas 4 which is wound around the periphery of the frame 3 and fixed to the frame 3 and stretched in the frame 3.

The canvas 4 is composed of a vinyl chloride sheet 6 laminated with a reinforcing cloth 5 on the back side, and as shown in FIG. 2, the peripheral edge 4a of the canvas 4 is wound along the frame 3 and the surface fastener 7 for fixing the terminal is used. The peripheral edge 4a of the canvas 4 is attached along the peripheral edge of the frame 3 to fix the canvas 4. Instead of the hook-and-loop fastener, a fixing means such as a hook may be used.

In order to secure a rear view in the front half of the canvas 4, an opening 8 is provided substantially in the center thereof, and a transparent soft vinyl chloride sheet 9 is set in the opening 8, and the periphery of the sheet 9 is set on the canvas 4. It is fixed by high frequency welding.

In order to fix the cover body 1 thus constructed by stretching the canvas 4 on the frame 3 to the vehicle body side, although not shown, a bracket or the like is provided on the frame 3 and a conventional means such as bolting is used on the vehicle body side. Just fix it.

Further, the frame 3 has four front, rear, left and right as shown in FIG.
A hinge portion is provided at a position, and in this embodiment, the joint 1
Both ends of 0 are pivotally supported by the pin 3 with respect to the frame 3, respectively, and after this hinge part is bent and folded, it can be compactly stored in the trunk room.

Further, in the present application, the hinge portion is provided on the frame 3 as described above, and the vehicle body or the canvas 4 is not damaged by the edge of the hinge portion, and is not rattled due to vibration in the vehicle. A collar 11 is slidably inserted in the frame 3 so as not to exist.

When mounting the cover body 1 on the opening 2, after expanding the frame 3, the collar 11 is fitted onto the outer periphery of the joint 10 forming the hinge portion (see FIG. 6) to maintain the expanded shape of the frame 3. At the same time, the adverse effect of the edge of the hinge portion can be eliminated.

Further, in this embodiment, four hinge portions are set on the frame 3, but two hinge portions may be set only on the left and right sides, and the collar 11 is attached to all four hinge portions. It may be done.

In the figure, reference numeral 12 indicates a reinforcing frame, and the reinforcing frame 12 is sewn on the back surface side of the canvas 4 along the center vehicle width direction.

As described above, in the cover body 1 according to the present application, since the cover body 1 is composed of the frame 1 and the canvas 4, the weight can be remarkably reduced as compared with the conventional back door made of a thin metal plate, and the back body can be made lighter. It is possible to diversify the design by properly using the door and the cover body of the present application.

Further, when the back door is used, the cover body of the present application is configured such that the frame 3 is foldable via the hinge portion so that it can be compactly stored in a luggage compartment or the like. To attach the cover body 1 to the opening on the vehicle body side, by sliding the collar 11 onto the hinge portion in a shape in which the frame portion 3 is expanded around the hinge portion, the expanded shape of the frame 3 can be held securely and the hinge The edge of the part does not damage the vehicle body, canvas, etc., and contributes to the stable mounting of the cover body 1 on the vehicle body side without rattling of the hinge part due to vibrations etc. while the vehicle is running. It has high practical value.
