DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a folding door for a vehicle.

(Prior Art) Generally, as shown in FIGS. 7 and 8, a vehicle folding door has a front end portion at a front edge of a door opening O formed on a side surface of a vehicle body B in a vehicle width direction via a first hinge pin 1. The first door 2 rotatably attached to the first door 2, and the front end portion to the second end of the first door 2 at the rear end portion.
A guide door 5 is provided on the upper edge of the door opening O, which is provided with a second door 4 rotatably assembled in the vehicle width direction via a hinge 3 and is rotatably erected on the upper rear end of the second door 4. It is assembled to the fixed guide rail 6 so as to be slidable in the front-rear direction, and the gap between the peripheral edge of the door opening O and the ends of the doors 2 and 4 is sealed by the weather strips 2A and 4A fixed to the doors 2 and 4 side. Has been done.

According to this structure, when the doors 2 and 4 are opened, the guide roller 5 slides forward along the guide rail 6 and the first door 2
Rotates inward, and the second door rotates outward. As a result, both doors 2 and 4 are folded and opened from the second hinge 3 in two.

(Problems to be solved by the invention) In the above-mentioned conventional folding door, when the doors 2 and 4 are opened, the two folded doors 2 and 4 project to the interior of the vehicle interior, so the door is located on the vehicle interior floor. A space for storing 2 and 4 is required. Therefore, as shown in FIG. 9, the passenger compartment floor F
The width of the step S1 at the bottom of the steps
It must be wide enough to accommodate the folded doors 2 and 4, and the width dimension of the step S2 of the next stage is shortened accordingly, and it is not possible to set the width suitable for getting on and off.

Further, since the outer sides of the doors 2 and 4 face each other when folded in two, the doors 2 and 4 interfere with each other if the doors 2 and 4 are curved outward. Therefore, it is not possible to give the doors 2 and 4 a curved shape to the outside in conformity with the curved shape of the side surface of the vehicle body B. Therefore, when the doors 2 and 4 are closed, the door surface and the vehicle body side surface do not align with each other and look good. bad.

Further, since the gap between the periphery of the door opening O and the ends of the doors 2 and 4 is sealed by the weather strips 2A and 4A fixed to the doors 2 and 4, the weather strip 2 is rotated as the doors 2 and 4 rotate.
A and 4A also rotate. Therefore, the weather strips 2A and 4A are easily deformed and worn, and the sealing property is poor.

The present invention aims to solve such problems.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention assembles one end rotatably in the vehicle width direction via a first hinge to an edge of a door opening formed in a vehicle body. A first door and a second door whose one end is rotatably attached to the other end of the first door via a second hinge in the vehicle width direction are provided on the other end side of the second door. A vehicle folding door in which guide rollers are assembled slidably in the front-rear direction on a guide rail fixed along the upper edge of the door opening, and both doors are folded in two from the second hinge to open. At the time of opening both doors, the first hinge and the second hinge are attached so that the first door rotates outward and the second door rotates inward, and the door opening. When the weather strip is fixed to the periphery of the and both doors are closed It is characterized in that the lip is brought into pressure contact with the inside of the ends of the first door and the second door.

According to the present invention, when the door is opened, the guide roller slides along the guide rail to the first hinge side end portion of the rail,
Along with this, the first door pivots outward, the second door pivots inward, and both doors are folded in two and opened. At that time, the two folded doors project outside the vehicle compartment. Therefore, there is no need to provide a door storage space on the passenger compartment floor, and the step width can be set to a dimension suitable for getting on and off.

Further, since both doors face each other when folded in two, even if the doors have a curved shape outward, they do not interfere with each other. Therefore, since it is possible to give the both doors a curved shape which is curved outward in accordance with the curved shape of the side surface of the vehicle body, when the both doors are closed, the door surface and the side surface of the vehicle body are aligned and improved in appearance.

Furthermore, since both doors open to the outside of the vehicle compartment, the weather strip can be provided on the vehicle body side. Therefore, since the weather strip itself does not rotate, deformation and wear are reduced and the sealing property is improved.

(Embodiment) The first embodiment of the present invention will be described below with reference to the drawings.
1 to 4 show a vehicle folding door according to an embodiment of the present invention. The folding doors are the first door 11 and the second door
A front end portion of the first door 11 is attached to a front edge of a door opening O formed at the center of the side surface of the vehicle body B by a first hinge 13 so as to be rotatable in the vehicle width direction. The front end of the second door 12 is attached to the rear end of the first door by a second hinge 14 so as to be rotatable in the vehicle width direction.

As shown in FIG. 1 and FIG. 4, the first door 11 and the second door 12 are formed on the respective doors 11 and 12 so as to be gently curved outward in accordance with the curved shape of the side surface of the vehicle body B. The window glass W fitted in the window opening is also curved outward in accordance with the door surface. A handle 12a for opening and closing the door is provided outside the front end of the second door 12.

As shown in detail in FIG. 5, the first hinge 13 is composed of a flat plate bracket 13a and an arched bracket 13c rotatably connected to the bracket 13a via a hinge pin 13b. Inside, and the arched bracket 13c is bolted inside the front end of the first door 11.
