The vicinity of one end of the connecting rod 12 is slidably held by a holding portion 2e formed in the case 2, as shown in FIG. 5, to prevent it from swinging in the vertical direction.

The other end of the bell crank 13a of the key cylinder 13 is connected to a rod 14 that pushes and pulls a locking/unlocking lever of a door lock (not shown), and when the key cylinder 13 is rotated clockwise in FIG. 1, the door lock is locked. It is designed to be unlocked by turning it counterclockwise. Note that the bell crank 13a is also interlocked with a knob (not shown) on the inside of the vehicle.

When the door lock is locked, the connect lever 9 is slid to the right with respect to the pin 10,
The left end 9c of the connect lever 9 is located at a detached position away from the rotation locus of the protruding piece 4a of the handle 4 to the right.

Also, when the door lock is unlocked by the key cylinder 13, the connect rod 12
The connect lever 9 is pushed to the left via
The end portion 9c enters into the rotation locus of the protruding piece 4a of the handle 4, as shown by an imaginary line 9' in FIG. It's getting old.

Next, the operation and handling of the embodiment of the present invention constructed in this manner will be explained.

When the door lock is in the unlocked state, when the finger pressing portion 5a of the push button 5 is pressed, the protruding piece 5b abuts the upper end surface of the connect lever 9, and the connect lever 9 is moved to the first position using the pin 10 as a fulcrum. Rotate counterclockwise in the figure.

Then, by pushing down the protruding piece 4a of the handle 4 that can come into contact with the lower surface of the end 9c of the connect lever 9, the handle 4 is rotated around the shaft 3 to the position shown by the imaginary line 4' in FIG. rotated clockwise,
It protrudes from the recess 2a of the case 2.

Grasp the protruding handle 4 and draw the imaginary line 4'' in Figure 3.
When the handle 4 is further rotated counterclockwise around the shaft 3 to the position indicated by , the end surface 4b of the handle 4 comes into contact with the stepped portion 7c of the release lever 7, and the release lever 7
At the same time, it rotates counterclockwise around the shaft 3, pushes down the rod 8, and releases the door lock.

After that, when you release your hands from the push button 5 and the handle 4, the urging force of the coil springs 6 and 11 will cause the
The handle 4 and the pushbutton 5 are rotated back to their original state shown in FIG. Further, the release lever 7 also returns to the state shown in FIG. 5 when the hanging piece 7d is pushed by the back surface 4c of the handle 4.

Next, the case where the door lock is in the unlocked state will be explained.

At this time, the connect lever 9 rotates the key cylinder 13 clockwise and connects the connect rod 12.
By pulling to the right, connect lever 9
The end 9c of the handle 4 is separated from the free end 4a of the handle 4,
It is located in a disengaged position where it is not engaged.

Therefore, even if the push button 5 is pressed and the connect lever 9 is rotated around the pin 10 in the counterclockwise direction in FIG.
It remains immersed within.

FIG. 6 shows another embodiment, which is different from the previous embodiment except for the connection lever, and is otherwise the same as the previous embodiment.

That is, in the embodiment shown in FIG. 6, the connect lever 9 is provided with a recess 9d, and by positioning the recess 9d below the protrusion 5b of the push button 5 in the locked state, the push button 5 and When locking with the connect lever 9 in a disengaged state,
Even if the push button 5 is operated to activate the protrusion 5b,
The protruding piece 5b is prevented from swinging due to the recess 9d and the connect lever 9 is not interlocked. By doing this, when the lock is in the locked state, nothing other than the push button 5 operates, so there is no wasted movement, smooth operation is achieved, and the link between the push button 5 and the handle 4 can be reliably disconnected. .

In the automobile door handle device of the present invention constructed and operated as described above, when the handle is not operated, the outer surface of the handle 4 is flush with the outer surface of the door panel, and when the door lock is locked, the handle 4 is pressed. Even if the button 5 is pressed, the handle 4 does not protrude from the recess 2a of the case.

Therefore, since there are no uneven parts on the door panel, even when the car is driving at high speeds, there is no turbulence in the air flow, increasing running resistance, or wind noise, and it also maintains an aesthetically pleasing appearance. Good too.

Moreover, the present invention can also produce the following effects.

(1) When the door lock is locked, the handle 4 does not protrude from the recess 2a of the case 2 even if the push button 5 is pressed. You can check it just by pressing it. Therefore, there is no need to grasp and pull the door handle, as is the case with conventional door handle devices.

(2) Similarly, when the door is locked, even if the push button 5 is pressed, the handle 4 remains recessed in the recess 2a, which prevents mishandling such as misoperation of the door handle or when parking. This provides good protection by preventing device damage or malfunction due to tampering.

(3) Conventionally, doors can be locked without using a key by pushing down a knob inside the vehicle to lock the door, and unlocking the door handle while closing the door.
It is possible to prevent the key from being forgotten in the vehicle interior due to the so-called keyless lock operation. That is, in the device of the present invention, when performing a keyless lock operation, the following actions are required: pressing a push button and grasping the protruding handle, pushing down a knob in the vehicle interior, and closing the door while unlocking the handle. Since the keyless lock operation can be re-recognized compared to the conventional method, it is extremely effective in preventing the key from being forgotten inside the vehicle.

As described above, according to the present invention, since there is no recess in the door panel, turbulence in air flow is significantly reduced even when the automobile is running at high speed, reducing running resistance and wind noise, and improving the appearance quality. In addition, since the handle cannot be protruded when the lock is locked, the device is not damaged or malfunctions due to tampering, which improves device protection, and the keyless lock operation is slightly more complicated. This makes it possible to re-recognize the keyless lock operation, which is effective in preventing the key from being forgotten inside the vehicle.
