Description

[Detailed Description of the Invention] The present invention relates to an automobile rear door opening/closing device in which a clutch mechanism is interposed in the operation transmission path of the device which allows the automobile rear door to be opened and closed by rotation of an operating lever.

Conventionally, such a door opening/closing device, as shown in Fig. 1, rotates a crank rod in half by rotating an operating lever, and converts this half rotation into a linear motion using a lever to open and close a hook on the rear door of a car. However, in this opening/closing device, the control lever and the rear door are linked in a series, and the rear door opening width control lever is always in the raised state, so the driver cannot use the control lever while the rear door is open. The vehicle was in the way and the act of getting off the train was obstructed.

Therefore, there have been drawbacks such as the inability to deal with cases where rear seat passengers and the driver wish to get off the train at the same time, especially in an emergency.

In view of this drawback, the present invention eliminates the above drawback by intervening a clutch mechanism in the middle of the rear door opening/closing transmission mechanism, so that when a passenger in the rear seat opens the rear door, the operating lever is not pulled up. An example of the implementation of the present invention will be described below based on the drawings. 1 is a receiver whose both ends are screwed onto a receiver 4 and a stay 5 on the vehicle floor 3 under the front seat 2. 4' is a crank rod rotatably supported, and an operating lever 6 is screwed onto the end of the crank rod 1 on the driver's seat side.

On the other hand, the other end of the crank rod 1 has an inclined surface 7 at its side end.
A side plate 9 having a claw piece 8 formed on the upper end thereof.
The lower end of the is fixed.

Reference numeral 10 denotes a clutch plate having a substantially U-shaped cross section, which sandwiches the side plate 9 and extends from the rear wall surface 1 of the side plate 9.
1 is opposed to the inner wall surface 12 of the clutch plate 10, and its lower end is rotatably supported on the crank rod 1, and its upper end is connected at one end to a hook 13 for opening and closing the rear door. The other end of the operating rod 14 is pivotally connected, and the door is opened and closed by rotation of the clutch plate 10.

Also, long holes 15, 15 are formed on both side walls of the clutch plate 10-.
The engagement pin 16 is supported in the elongated holes 15, 15' so as to be movable up and down.

Note that the elongated holes 15, 15' are installed at positions such that the engaging pin 1'6 is located at the lower end, and the engaging pin 16 is engaged with the claw piece 8 at the upper end of the side plate 9, and conversely, it is located at the upper end. The time is the position where the locked state is released.

Further, the crank rod 1 is attached to both ends of the engagement pin 16.
Both ends of a torsion spring 19 rotatably supported by a spring presser 18 are hooked onto a projecting piece 17 protruding from the stay 5 at the right position.

Next, to explain the usage state of the rear door opening/closing device according to the present invention, when the rear door is in the closed state, the operating lever 6 screwed to one end of the crank rod 1 is in the forward position, while the other end of the crank rod 1 is in the forward position. The side plate 9 fixed to the end is the fifth
The clutch plate 10, which is positioned slightly inclined to the right as shown by the chain line in the figure, and which is pivotally attached to one end of the operating rod 14 for opening and closing the rear door, is also positioned in the same manner as the side plate 9. The engagement pin 16, which is vertically movably supported in the elongated holes 15 and 15' of the clutch plate 10, is pushed to the upper end by the action of the torsion spring 19, and the clutch plate 10 is in a free state with respect to the side plate 9.

When the operating lever 6 is pulled in order to open the rear door from this state, the crank rod 1 rotates in the direction A, and when the side plate 9 rotates in the same direction, the rear wall surface 11 of the side plate 9 is moved against the clutch plate 10. Since the clutch plate 10 contacts the inner wall surface 12 and rotates together to the solid line position shown in FIGS. 4 and 5, the operating rod 14 pivoted to the upper end of the clutch plate 10 moves linearly toward the rear door. The hook 13 is released to open the rear door.

In this state, the engagement pin 16 is pulled to the lower end position of the elongated holes 15, 15' by the action of the torsion spring 19, so the engagement pin 16 is in a state where it is engaged with the claw piece 8 at the upper end of the side plate 9. It becomes.

Next, when the operating lever 6 is tilted forward from this position to close the rear door, the crank rod 1 rotates in the direction B, and as the side plate 9 rotates in the same direction, the side plate 9 and the clutch plate 10 rotate. is integrated by the locking action of the claw piece 8 and the engagement pin 16,
Both rotate as one in the direction B, and the operating rod 14 also returns in the same manner to close the rear door.

Immediately before the rear door is completely closed, the locking state between the engagement pin 16 and the claw piece 8 is released by the torsion spring 19, but since the rear door continues to move due to inertia during the closing operation, it is completely closed without any problem. It is now possible to close your mouth.

In addition, when passengers and the driver get off the vehicle at the same time in an emergency, etc., when the passenger first opens the rear door by himself or herself, the operating rod 14 moves toward the rear door and the clutch plate 10 rotates in the direction B. Since the locking state between the engagement pin 16 and the claw piece 8 is released, the rotational movement of the clutch plate 10 is not transmitted to the side plate 9, the crank rod 1, and the operating lever 6, and therefore the operating lever 6 maintains the forward tilted state, and the driver can simultaneously open the front door and get off the vehicle without being obstructed by the operating lever 6.

In addition, in cases where the clutch plate 10 and side plate 9 are not integrated and the rear door is open, if you wish to connect the side plate 9 halfway and close the door using the operating lever 6, the operation When the lever 6 is rotated in the direction A, the inclined surface 7 formed on the left side of the claw piece 8
contacts the engagement pin 16 located at the lower end of the elongated hole 15° 15', and moves the engagement pin 16 upward against the downward pulling action of the torsion spring 19, forcing the claw piece 8 Since the engaging pin 16 is locked, the door can be closed using the operating lever 6 in the same manner as in normal opening/closing operations.

In the present invention, the side plate 9, clutch plate 10, etc. are disposed at one end of the crank rod 1 as shown in the drawings, but their mounting positions may be arbitrary depending on the type of vehicle to which such a device is installed.

In short, the present invention provides a clutch in which a claw piece 8 is provided on a side plate 9 fixedly supported by a crank rod 1 that interlocks with an operating lever 6, and a retaining pin 16 that engages and disengages from the claw piece 8 is supported in a vertically movable manner. The plate 10 is attached to its inner wall surface 12
is rotatably supported at its lower end on the crank rod 1 so as to face the rear wall surface 11 of the side plate 9, and is rotatably supported on the engagement pin 16 on the right side of the crank rod 1. The end of the torsion spring 19 is hooked, and the end of the operating rod 14 for opening and closing the rear door is pivotally attached to the upper end of the clutch plate 10. To open and close the door, the rear wall surface 11 of the side plate 9 presses the inner wall surface 12 of the clutch plate 10 during the opening operation of the side plate 9 and the clutch plate 10, and conversely, the rear wall surface 11 of the side plate 9 presses against the inner wall surface 12 of the clutch plate 10 during the closing operation. The pawl piece 8 engages the engagement pin 16 of the clutch plate 10 so that they are integrally linked, so that the rotation of the operating lever 6 is caused by the rotation of the crank rod 1, the side plate 9, the clutch plate 10, and the operating rod. 14, and the rear door can be opened and closed.However, in an emergency, etc., when passengers and the driver get off the train at the same time, even if the passenger opens the rear door by himself/herself, the action of the torsion spring 19 will cause the claw piece to close. Since the locking action between the clutch plate 8 and the engagement pin 16 has been released, the clutch plate 10
and the side plate 9 are not interlocked, so the opening operation of the rear door is not transmitted to the operating lever 6, and the operating lever 6 is in the forward position even though the rear door is open, so the driver cannot move the operating lever. You can get off the train at the same time as passengers without being obstructed by 6.

Furthermore, if the inclined surface 7 is formed at the side end of the claw piece 8, the clutch plate 10 and the side plate 9 are not integrated as described above, but can be integrated from the middle when the rear door is open. If you wish to do so, simply rotate the operating lever 6 and rotate the side plate 9 in the rear door opening direction to forcibly lock the claw piece 8 and the engagement pin 16, and then close the side plate 9 and the clutch. The plate 10 can be integrated, and the rear door can then be opened and closed using the operating lever 6.

Therefore, according to the present invention, the so-called one-way clutch mechanism that allows transmission from the operating lever 6 to the operating rod 14, but not from the operating lever 14 to the operating lever 6, can be used to protect passengers and the driver in an emergency. The practical effects of this, such as making it possible to get off the train at the same time and ensuring the safety of the driver, are enormous.
