Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a double door device for a motor vehicle.

Conventionally, automobile doors have been opened on one side, with one end in the direction of travel pivoted to a lever that protrudes from the frame, so opening and closing operations are restricted in narrow spaces or areas with obstacles, causing inconvenience. There are many cases where I feel it. Therefore, the applicant researched and developed a double door mechanism for automobiles, and filed an application (Patent Application No. 170026 of 1982).
However, this door mechanism required extra space for the operating discs that were pivotally supported within both sides of the door, which had the disadvantage of restricting the installation of the window glass inside the door. .

In order to solve the above-mentioned drawbacks, the present invention is characterized in that the double-swings of an automobile door are made compact and installed on both sides of the inside of the door, thereby facilitating the installation of window glass.

Hereinafter, the configuration of the present invention will be explained with reference to embodiment figures.

Step portions 3, 3' are provided at upper positions on both sides of the door 2 that fits into the door frame 1 on both sides of the vehicle body, and the door 2 is provided at positions below the step portions 3, 3'.
The actuating plate 6 is fixed by fixing the substrates 4, 4 in parallel with both side surfaces of the substrates 4, 4, and providing a pivot 5 at the center of the inner surface of the substrates 4, 4.
The actuating plates 6, 4 of the substrates 4,
The lower ends of the upper connecting rods 7, 7' are placed near both ends of the 6,
The upper ends of the lower connecting rods 8, 8' are loosely attached, and the upper claw shafts 9,
9', and at the same time, holes are made in the lower frame bodies on both sides of the door 2, and the lower pawl shafts 10, 10' are loosely fitted therein.
The upper pawl shafts 9, 9' and the upper connecting rods 7, 7' are loosely connected, and the lower pawl shafts 10, 10' and the lower connecting rods 8, 8' are loosely connected, and the lower connecting rods of the actuating plates 6, 6 are loosely connected. A spring 11 is tensioned between the base plate 4 and the loose connection with the rods 8, 8', and a projecting piece 12 is provided protruding from the right end of the actuating plates 6, 6.
The projecting piece 12 is fitted into the vertically elongated hole 14 of the arm plate 13 which is provided in a more protruding manner, the central position of the T-shaped lever 15 is pivotally attached to the arm plate 13, and the lower surface of the outer arm of the T-shaped lever 15 is fitted with the projecting piece. 12 and the operation lever 17 of the external handle 16, 16' provided on both sides of the outer surface of the door 2.
The inner arm rod of the mold lever 15 is connected to the lever link mechanism 1.
8 and 18', and the internal handles 19 and 19' provided on both sides of the inner surface of the door 2 and the lower arm rod of the T-shaped lever 15 are loosely connected with the connecting rods 20 and 20'. A stopper 21 that can prevent the operation of the actuating plate 6 is pivotally connected to the base plate 4 with a pin 21', and lever link mechanisms 22, 22' are connected to the stopper 21.
are linked with the lock buttons 23, 23', recesses 24 are provided on both sides of the door 2 with the lower pawl shafts 10, 10' facing each other, and a bracket 26 with a roller 25 pivotally supported is fitted into the recess 24. , bracket 2
6, a long plate 27 protruding from the back surface of the recess is made to protrude from the hole on the back surface of the recess so as to face the claw shaft front and rear, and the recess 24
A wedge-shaped stopper 28 is provided protruding from the claw shaft on the opposite side, a locking pin 29 capable of locking the stopper 28 is provided protrudingly from the long plate 27, and a spring is attached to the rear end of the long plate 27 and the recess 24. The claw shaft holding mechanisms 31, 31' are provided with the claw shaft holding mechanisms 31, 30 stretched.
Holes 32, 3 that fit with the rollers 25, 25 of 1'
2' are provided on both inner surfaces of the door frame 1, and locking holes 33, 33', 34, 34' that engage with the upper claw shafts 9, 9' and the lower claw shafts 10, 10' are provided. It is what it is.

Next, the effects of the present invention will be explained with reference to embodiment figures.

Lock button 23, 23' of car door 2
When the actuator is raised from inside the vehicle, the stoppers 21 of the boards 4, 4 are raised and the lock of the actuating plate 6 is released. When opening the door 2 using the external handle 16, when the operating lever 17 inside the external handle 16 is rotated with a fingertip, the T-shaped lever 15 is rotated by the lever link mechanism 18 as shown by the arrow in FIG. move,
The actuating plate 6 is rotated by holding the protrusion 12 on the right side of the actuating plate 6 with a T-shaped lever 15 and pushing it downward against the elasticity of the spring 11. , 8, the upper pawl shaft 9 slides downward and the lower pawl shaft 10 slides upward and disengages from the locking holes 33, 34 of the door frame 1. As the lower pawl shaft 10 rises, the wedge-shaped The stopper 28 is guided above the locking pin 29, and the door 2 is opened by pulling the external handle 16 in that state. This is to maintain the return operation of the pawl shaft. When the internal handle 19 of the door 2 is used to open the door, the T-shaped lever 15 is rotated via the connecting rod 20 to disengage the upper and lower pawl shafts. When the opened door 2 is closed, the roller 25 protruding from the right side of the door 2 is pressed by the door frame 1, and the elongated plate 27 moves backward against the elasticity of the spring 30 to close the locking pin. 29 releases the locking of the stopper 28 of the pawl shaft, and the actuating plate 6 is actuated by the elasticity of the spring 11.
is rotated in the opposite direction to return to its original position, causing the upper and lower pawl shafts 9 and 10 to protrude in the vertical direction and engage with the locking holes in the door frame 1, thereby maintaining the closed state of the door.

External handle 16' and internal handle 1 on the left side of door 2
Also at 9', the upper and lower pawl shafts 9' and 10' are slid into the door 2 by the rotation of the actuating plate 6 which is pivotally mounted on the base plate 4, and the left opening operation is performed centering on the upper and lower pawl shafts 9 and 10 on the right side. By making the guidance mechanism for the upper and lower pawl shafts more compact and integrating them into the door 2, the installation of the glass inside the door 2 is not hindered in any way, and the car door 2 can be opened smoothly in both directions. It has the remarkable effects mentioned above, such as improving convenience.
