BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to a double-opening device of automobile doors, which can be operated from both inside and outside the doors and could serve for right-side opening by supporting at the left-side portion and for left-side opening by supporting at the right-side portion.
BACKGROUND ART
Conventionally, automobile doors are operated by a single-opening mechanism, where one end of the door facing the running direction is hinged to the door support protruding from the body frame, the other end of the door is provided with a locking device, with which the handles provided on the inner and outer sides of the door are operated together to open or close the door. This single-opening mechanism is often inconvenient, as the opening or closing operations are restricted when the automobile is parked in a limited space or near other obstacles.
The purpose of the present invention is to eliminate such restrictions to the opening and closing of automobile doors, and to make it much easier to get in and out of an automobile by providing doors with a double-opening mechanism, which would allow doors to be opened from both the left and right sides.
DISCLOSURE OF INVENTION
This invention refers to the double-opening mechanism for automobile doors, where frame plates are attached to the inner sides of the door frame on both sides by means of hinges, the right and left frame plates are fixedly joined on both sides of the door by the said hinges, providing locking pieces in the groove defined in the both sides of the door at the upper and lower positions of the left and right frame plates, the engaging pawl plates and pawl shafts furnished inside the door with the locking pieces of the frame plates, the center of the operating plate at its center portion on both sides of the door, connecting both ends of the operating plate being operated together with the pawl plates and the pawl shafts by means of connecting rods, the handle provided on the inside and outside of the door and operating plate with a lever-link mechanisms separately, engaging the pawl plate and the pawl shaft with respect to the locking pieces while rotating the operating plate, such state is maintained and the door is opened with its rotational mechanism at the hinge of frame plate on the other side, the holding mechanism of pawl plates and pawl shafts being released and connected with locking pieces of said frame plates when door is closed. The air-tightness on both sides of the door is thus increased and the hinges are strengthened. The double-opening operation can be performed easily by the handles provided on the inner and outer sides of the door.
