Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an automobile back door.

[0002]

[Prior Art]

 In a vehicle with a luggage compartment at the rear of the vehicle body that allows the luggage to be taken in and out through the opening on the rear surface of the vehicle body, the back door that opens and closes the rear opening is a double door that opens and closes on both sides in the horizontal direction, and a door. It is known that the upper edge of the main body can be opened and closed vertically, but it is common to open and close the top and bottom except for large trucks such as commercial trucks.

By the way, an automobile having a relatively high cabin has been developed so that a long baggage can be carried in a vertically extended state, for example, in the case of hanging and carrying clothes. If a back door that opens and closes up and down is installed in a large vehicle, the upper and lower lengths of the back door become long, which requires a large space in the rear to open the back door.

Therefore, as shown in FIG. 5, in the back door 22 that opens and closes the rear opening of the vehicle body 21 in the vertical direction, the upper edge of the rear confirmation glass window 24 provided in the door body 23 is vertically moved by the hinge 25. It has been proposed to open and close the glass window 24 and open / close the glass window 24 when the rear space is small.

[0005]

[Problems to be solved by the device]

 However, in the configuration shown in FIG. 5, since the distance H from the floor of the passenger compartment to the lower end of the glass window 24 is long, it is difficult to load and unload luggage with the glass window 24 open. There was a problem that improvement of cargo handling cannot be expected.

In view of the above conventional problems, the present invention has an object of providing a back door of an automobile that has a door body that opens and closes vertically and that allows easy loading and unloading of luggage even when the rear space is narrow. And

[0007]

[Means for Solving the Problems]

 According to the present invention, one side edge of a door frame is horizontally pivotably supported on one side edge of a rear opening of a vehicle body, and the top edge of the door body is vertically pivotable on an upper side of the door frame. It is characterized in that damper stays are interposed between both sides of the door body and both sides of the door frame.

[0008]

[Action]

 According to the present invention, by opening the door body upward while keeping the door frame closed, it can be used as a vertical opening / closing type backdoor, in which case the door frame only remains in the rear opening. Therefore, almost all of the rear opening can be opened, and the workability of cargo handling can be maximized. In addition, the door body can be protected from rain during cargo handling. On the other hand, if the rear space is narrow and the door body cannot be fully opened upward, it is difficult or impossible to open and close the door body, but in that case one side edge of the door frame is Since it is supported so that it can be opened and closed horizontally, by opening the other side of this door frame to the rear, the opening required for cargo handling can be secured even in the half-opened state, and cargo handling can be performed without hindrance. You can Furthermore, the door frame is attached to the vehicle body so that it can be opened and closed horizontally, and the door body is attached to this door frame so that it can be opened and closed vertically. Since only the door body is opened and closed vertically as compared to the case where a large door body is attached, the vertical opening and closing weight becomes lighter, and a small-output damper stay can be used.

[0009]

【Example】

 An embodiment of the present invention will be described below with reference to FIGS.

In FIGS. 1 and 2, reference numeral 1 is a vehicle body of a one-box type automobile, 2 is a vehicle interior, and a rear portion of the vehicle interior 2 is a luggage compartment. Reference numeral 3 denotes a rear opening of the passenger compartment 2, which is openably and closably closed by a back door 4. The back door 4 is composed of a frame-shaped door frame body 5 along the opening edge of the rear surface opening 3 and a door body 6 that closes the inner opening of the door frame body 5.

The door frame body 5 is attached to the right side edge of the rear opening 3 by a pair of upper and lower hinges 7 (see FIG. 3) arranged in the lower half of the right side edge thereof so that the door frame body 5 can be opened and closed horizontally. Has been. Further, a handle 8 (FIG. 2) for opening and closing and a lock mechanism 9 (FIG. 1) are provided on the left side of the door frame 5.

An upper edge of the door body 6 is attached to the upper side of the door frame 5 via a pair of left and right hinges (not shown) so as to be vertically openable and closable. The door body 6 is formed so that a frame portion 6a at its peripheral portion overlaps with the inside of the door frame body 5 in the vehicle front-rear direction. A glass window 10 for rearward confirmation is provided inside the frame 6a in the upper half of the door body 6. A pair of damper stays 11 are interposed between the frame portions 6a on both sides of the upper part of the door body 6 and the both sides of the door frame body 5, so that the door body 6 can be lightly opened upward and opened. It is configured to hold. A handle 12 for opening and closing is provided adjacent to the handle 8 of the door frame 5 on the lower left edge of the door body 6.

In the above configuration, when the rear space is narrow and the door body 6 cannot be fully opened upward, one side edge of the door frame body 5 is a horizontal hinge 7 as shown in FIG. Since it is supported so that it can be opened and closed in any direction, by opening the other side of this door frame 5 rearward, even if the door frame 5 is half opened, the opening necessary for cargo handling is secured. It is possible to carry out cargo handling without any hindrance.

On the other hand, when there is sufficient rear space, as shown in FIG. 4, it can be used as a vertical open / close type back door by opening the door body 6 upward while keeping the door frame 5 closed. .. At that time, since only the door frame 5 remains in the rear opening 3, almost the entire rear opening 3 can be opened, and the workability of cargo handling is very good. Also, when it rains, the door body 6 can be used as a shelter so that it can be loaded without being wet.

It should be noted that the present invention is particularly effective in a vehicle in which the height of the vehicle compartment 2 is relatively high so that clothes or the like can be hung and transported as shown in the illustrated example. It goes without saying that the same effect can be exerted by applying the present invention to a back door of an automobile having a room height.

[0016]

[Effect of the device]

 According to the back door of the vehicle of the present invention, one side edge of the door frame is horizontally openably and closably supported on one side edge of the rear opening of the vehicle body, and the upper edge of the door body is attached to the upper side of the door frame. It is pivotally supported so that it can be opened and closed in the vertical direction, and damper stays are interposed between both sides of the door body and both sides of the door frame, so open the door body upward with the door frame closed. As a result, it can be used as an up-and-down opening type back door, in which case almost all of the rear opening can be opened, and the workability of cargo handling is extremely good, and when it rains, the door body can be used as a shelter for cargo handling. On the other hand, when the rear space is small and the door body cannot be fully opened upward, one side edge of the door frame is supported so that it can be opened and closed in the horizontal direction. The opening required for cargo handling can be easily secured by opening it halfway toward the rear, and cargo handling can be performed without any problems. Furthermore, since the door frame is attached to the vehicle body so that it can be opened and closed horizontally and the door body is attached to this door frame so that it can be opened and closed, the door body only needs to be opened and closed up and down. Therefore, a small output can be used as the damper stay, and the damper stay can be constructed at low cost.
