ランクロツドａが扉開放方向に回転し、不意に後
扉が開放するため甚だ危険であつた。 As shown in FIG. 1, conventional door opening/closing devices include a crank rod a rotatably disposed on the vehicle floor below the front seat, an operating lever b attached to the end of the crank rod a on the driver's seat side, and an operating lever b attached to the driver's seat side end. A rotation conversion mechanism d is provided at the end of the crankshaft to open and close the hook c of the rear door by converting the rotation of the crankrod a into a linear motion, and the rear door is opened and closed by the swinging of the operating lever b via the crankrod a, etc. It is designed to make you operate it. However, if a vehicle equipped with such an opening/closing device is hit from behind, the components located above the rotational axis of the crank rod a, namely the operation lever b, the escape curve of the drive shaft in the crank rod a, and the crank rod As shown in Figure 2, the rising part of the other end of a generates a rotational moment in the door opening direction (W 1 L 1 + W 2 L 2
+...+WnLn) x 30G (Wn is the weight of each component,
Since Ln acts as the vertical distance between the axis of rotation and the center of gravity of each component, such an impact causes the crank rod a to rotate in the door opening direction, causing the rear door to open unexpectedly, which is extremely dangerous.

ている。 In view of the above-mentioned drawbacks, the present invention provides an opening/closing device in which a crank rod is rotated by the swinging of an operating lever, and the rotation of the crank rod is converted into a linear motion to open and close the hook of a rear door of an automobile. A balance member is provided that applies a rotational moment in the door closing direction that is necessary and sufficient to cancel out the sum of rotational moments in the door opening direction that are applied by each component located above the rotational axis of the crank rod due to the impact of time. An embodiment of the present invention will be described below with reference to the drawings.The crank rod is installed at an appropriate location below the rotation axis of the crank rod to solve the above drawbacks.One embodiment of the present invention will be described below with reference to the drawings. Receipt 3 on both ends,
The crank rod 1 is rotatably supported at the end of the crank rod 1 on the driver's seat side.
A rotation conversion mechanism 8 connected to a hook 7 for opening and closing the rear door via a connecting rod 6 is installed, and the crank rod 1 is rotated by the swinging of the operating lever 4, and the rotation of the crank rod 1 is controlled by the rotation conversion mechanism 8. It is configured to open and close the rear door by converting it into linear motion.

用的効果甚だ大なるものである。 In short, the present invention rotates the crank rod 1 by swinging the operating lever 4, and
In an opening/closing device that opens and closes the hook 7 of the rear door of a car by converting rotation into linear motion, the impact caused by a rear-end collision causes damage to each component located above the rotation axis 10 of the crank rod 1. A balance member 9 is provided at an appropriate location below the rotational axis 10 of the crank rod 1 to apply a necessary and sufficient rotational moment in the door closing direction to cancel out the total rotational moment in the door opening direction. The practical effects are enormous, such as being able to cancel out the rotational moment in the door opening direction due to the impact caused by a rear-end collision, preventing the rear door from opening unexpectedly and ensuring the safety of passengers. It is something.
