Abstract

PURPOSE:To aim at simplification in structure and reduction in a door open- close possessory area, by attaching a pair of doors, opening or closing so installed, where a car body faces opposite to each other, and a roof part pivotally to the roof part proximate to a side part opening opposite to each other. CONSTITUTION:Each of symmetrical doors 26 and 28 are constituted entirely in the same form. Therefore, for example, if a door 26 at the right is turned up and down centering one a hinge part 30, the front roof door part 26R and the right side door part 26S take an up position in relation to a down position opening or closing and a corresponding front roof opening part each at the body side and right boarding side and alighting opening part. And, for example, the hinge part 30 at the right door 26 is set up and around an upper end of a left side boarding and alighting opening part to be opened or closed by a left side door part 28S of the left door 28 in a fixed roof part 24, so that maximum projecting length L toward the outside from a side face part 12 at the right in the car body of the right door 26 can be made smaller. Therefore, even in a narrow place, opening or closing of the doors is possible.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention is directed to a butterfly mounted on the roof of a vehicle body in order to open and close openings for getting in and out and the roof opening following the openings provided on opposite side surfaces of the vehicle body. The present invention relates to an automobile door structure forming a so-called gull wing type door.

(Prior art) In a passenger car, etc., openings for getting in and out are provided on each of the opposing left and right side surfaces of the vehicle body, and a roof opening that continues from each opening for getting in and out is provided in the roof of the vehicle body. The opening for getting in and out of the vehicle and each of the roof openings following it are opened and closed by a pair of left and right doors that are hinged to a position close to one end of each roof opening in the roof section and can be rotated up and down. , so-called gull-wing type doors are known. A pair of left and right gull wing doors in an automobile employing such gull wing doors has conventionally been developed, for example, in Japanese Utility Model Application No. 58-8615.
As shown in the above publication, the hinge parts that are hinged to the roof part are arranged at opposite positions sandwiching the center part of the roof part in the left and right direction.Therefore, the left and right openings for getting in and out The roof openings formed to continue to each of the sections widen from the upper ends of the left and right side sections to a position that does not reach the center of the roof section in the left-right direction.

(Problems to be Solved by the Invention) As described above, the gull wing type door is hinged to the roof part by the hinge parts arranged at opposite positions sandwiching the center part in the left and right direction of the roof part. It is rotated up and down as a rotating shaft part, and the opening for getting on and off and the roof opening following it are in a closed state at the lowered position, and
The opening is assumed to be in the raised position; however, when the opening is assumed to be in the raised position, the lower end thereof is flipped up significantly outward from the side surface of the vehicle body. Therefore, a gullwing type door usually requires a relatively large space outside the side of the vehicle body to open and close.

Therefore, in order to reduce the space required outside the side of the vehicle when opening and closing the gullwing type door,
For example, it is considered to have an upper half-rest and a lower half-rest, one end of which is hinged to the roof part, and the upper half-rest and the lower half-rest are connected via a hinge part. .

In such a device, when the ingress/egress opening and the roof opening following it are assumed to be in the raised position in order to open, the lower half-rest is rotated by the hinge portion relative to the upper half-rest. The length of the outward protrusion of the side surface of the vehicle body is reduced, and opening and closing is possible even if the space outside the side surface of the vehicle body is relatively small.

However, such a gullwing type door in which the upper half and lower half are connected via a hinge part has the disadvantage that the structure is complicated, and it is difficult to obtain sufficient strength. It is easy to become, and furthermore,
There is a problem in that there is a possibility that sufficient sealing performance may not be obtained at the connecting portion between the upper half-hole and the lower half-hole.

In view of the above, the present invention provides a method for opening and closing openings for getting in and out provided on each of the opposing left and right side surfaces of the vehicle body and each roof opening provided on the roof section following the openings. It is provided with a pair of doors that are hinged to the roof portion at one end and can be rotated up and down, and such doors are capable of ensuring sufficient strength and sealing performance without complicating the structure. An object of the present invention is to propose an automobile door structure that can effectively reduce the space outside the side surface of the vehicle body required for opening and closing.

(Means for Solving the Problems) In order to achieve the above-mentioned object, an automobile door structure according to the present invention has an opening for getting in and out provided on one of the opposing left and right side surfaces of the automobile body. a first door that opens and closes a roof opening and a roof opening that follows it, and a second door that opens and closes an entrance and exit opening provided on the other of the opposing left and right side surfaces of the vehicle body and a roof opening that follows it. a first hinge portion that hinges the first door to a position near the upper end of an entry/exit opening provided on the other of the left and right side portions of the fixed roof portion of the vehicle body; and a second door. and a second hinge portion that is hinged to a position near the upper end of an opening for getting on and off provided on one of the left and right side portions of the fixed roof portion.

(Function) In the automobile door structure according to the present invention configured as described above, the first and second doors are rotated up and down using the first and second hinge parts as rotating shafts, respectively. The openings for getting in and out and the roof opening following the openings provided on the left and right side surfaces can be opened and closed. The first hinge portion is located near the upper end of the opening for getting in and out that is opened and closed by the second door, on the opposite side from the opening for getting in and out that is opened and closed by the first door hinged thereto. The second hinge portion is arranged at a side of the entrance/exit opening opened/closed by the first door, which is opposite to the entrance/exit opening opened/closed by the second door hinged thereby. It will be placed near the top end. Therefore, when each of the first and second doors is raised and rotated to open the corresponding entrance/exit opening and the subsequent roof opening, each of the first and second doors is placed outside the left and right sides of the vehicle body. This requires a relatively small amount of space.

Furthermore, since neither the first nor the second door is configured such that the upper and lower half-rests are connected via a hinge, the structure is not complicated and sufficient Strength and sealing properties will be ensured.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.
