(,'I2) is a coiled spring wound around the shaft (2G) between one handle arm (roll) and the upright piece (goods), and one of the extending ends (32a) is locked to the upright piece (32b), and the other extending end (32b) is locked to the handle arm (to), and this coiled spring (
Handle arm (21111) (211+
is always directed toward the fully closed position (clockwise in Figure 6). The biasing force of this coiled spring (321) is due to the locking/unlocking collar (1) by the over center spring (Sa).
The holding force is substantially smaller than that of 6).

Another coiled spring (
33) is wound around one extending end ('33a) of this coiled spring (3:() is an upright half-length), and the other extending end (33b) is attached to the handle arm (of the row). The coiled springs (33) are respectively engaged with the upper edges of bent pieces (34a) bent rightward from the lower front edge of the pivot plate (34) which is pivotally connected to the shaft (27) on the inside. , pivot plate C (41
As shown in Fig. 5 and Fig. 6, the bent piece (:r4a

In FIG. 6, it is biased clockwise.

An abutment piece (34b) facing rearward is formed by bending the left downward rotation of the 111 bending piece (34a), and the handle arm (20) is attached to the abutment piece (34b) from the half-open position to the full rotation position. 1■
□The front edge of the arm (29a) of the handle arm (2, jll) comes into contact with the handle arm (2, jll) when it is in the dead position.

Thus, when the handle arm (/8) (2,9) is between the fully open position and the half open position, the coiled spring (prefecture only): rehandle arm (213) (21111) is turned in one line at full rotation. Then, handle arm t2B) (291
is between the half open position jl-5 and the fully open position, both coiled springs C (:I C+3+ cause the handle arm (

The biasing force of the spring is set in two stages.

At one end of one handle arm (row), an operating joint (31→) extending rearward and upward is provided, and this operating joint (
:) At the free end of (g), there is "in the above link (13)"
- Anchor 1 side bend (13b) is linked.

Thus, when the handle arm (281 (20)) is in the fully open position, the free end of the operating connection 1) is located in the uppermost position as shown in FIG.
The lower end of , as shown in Figure 2, is also located at the second most position.

When the handle arm vi (1 (b)) is in the half-open position as shown in Figure 37, the lower end of the handle arm vi (ri, connecting rod θ3) is
When the handle arm is in the neutral position as shown in Figure 3, the lower end of the handle arm (rotated) (when 2Jl is in the fully open position as shown in Figure 8, the connecting rod 03) is in the neutral position as shown in Figure 4. is located at the lowest position.

Therefore, the lower end side bent part (13a) of the IL rod (19)
The relationship between the long hole (20) of the connecting link (18) can be determined by operating the key cylinder or lock knob. 'Turn the lock lever (6) from the locking position 1θ) to the locking position fP
, 1, when the connecting link θ8) is moved downward via the connecting lever ([0)], the connecting lever (the handle arm μ5) (2)) changes from the fully open position to the half open position. In this unlocked position,
- When the handle arm (4) +) (201 is moved between the half-open position and the fully open position Jvl, the lower end bent part ('+3a) of the connecting rod (j3) moves in the long hole), Furthermore, when the handle arm (row (2, 111) is pushed in the opposite direction and moved from the half open position to the fully closed position, the connecting rod 03) pulls off the connecting link αB, and the lock/unlock lever (05)
from the unlocked position to the locked position (11).

The relationship between the bent part (+3a) on the lower end side of the connecting rod α3) and the long hole 1 layer of the release lever (5) is as follows.

By the release operation, the no-endor arm (7)
The relationship is such that when the release lever (5) is moved from the 511 position to the fully open position, the release lever (5) follows toward the release value ilj.

Next, the operation and handling of the device it of the present invention will be explained.

When the door is closed and locked, the door lock (the person is in the state shown in Figure 2) and the outside handle device (Bl is in the state shown in Figures 5 and 61). .

In this state, the handle (31) is in the fully open position with the four parts of the door panel (21) closed, and is flush with the door panel (21).
211N (The rti I/c has no protrusions or recesses at all, and does not interfere with the 1u speed running of the own mt il-' or generate wind noise.

To open the door, first turn the lock knob (ICN1) from inside the car, or press the lock/unlock lever (6) on the door lock (A) from outside the car.
) to the unlocked position 11:1''. Then, with this movement, the connecting link 08) is pulled down via the connecting lever 06), and the handle arm is further lowered via the connecting lever (IQ) f. (Example: 201 is moved to the half-open position (FIGS. 3 and 7).

This creates a gap between the handle (1) and the door panel (21) where you can insert your hand, so insert your hand here and turn the handle (+1) forward and upward until it is fully open. By pulling up, the connecting rod (ia) is pushed down, the release lever (5) is moved to the release position, and the intermediate lever (9) is moved to the release position.
) can be used to rotate the open lever (3) to the release position to release the latch and striker and open the door (Figures 4 and 8).

Pull your hand from the handle C41) to the coiled spring (32) (
33), the handle arm l:Z) (29
) is returned to the half-open position, and the release lever (
5) is also returned to the inoperative position (Figures 3 and 7).

Half-open position? After reaching Nao, turn to No Ndol Arm) IF
The i-force is biased only by the winding spring (32), and the biasing force of this winding spring (32) is substantially smaller than the holding force of the lock/unlock lever (6) by the over-center spring (8a). By being a handle arm (
28) (29) stops at the half-open position.

In this state, you can open and close the door as many times as you like by turning the handle (1) fully open five times.

In addition, in this example, the handle arm
(If you push the edge from the half-open position to the fully open position, the connecting rod (13) will be pulled up, and the connecting link (13) will be pulled up.
The lock lever (6) is moved toward the locked position (FIGS. 2 and 6). Therefore, there is an advantage that the so-called keyless lock can be performed conveniently by simply pushing the handle 031) from the half-open position to the fully closed position.

If you want to move the handle arm (a120He) to the fully closed position after getting on the vehicle with the handle arm (a120He) (steel in the half-open position and closing the door, use a separate device to move the handle arm (a120He) to the fully closed position. A known actuator that operates simultaneously with the vehicle can be used.

In addition, in the locked state, the handle can be changed from fully closed to half open or U°.
Even if you forcibly pull it out from the fully open position, the h6j unlock lever (6) will not be moved to the open lock position, and will simply operate in vain, making it impossible to release the engagement between the latte and the striker. It is also safe against vulgarity.

As is clear from the following, according to the present invention, except when operating the handle, the handle can be recessed into the four parts and the outer surface of the handle can be made flush with the outer surface of the door panel. When driving, there is no risk of the handle creating turbulence in the airflow, increasing running resistance or generating wind noise.In addition, there are no protrusions on the outside of the vehicle, improving safety. It is also meaningful because the appearance is also important.

However, in the present invention, 1 [
1. Lock 4 (74) Since the handle automatically protrudes to the half-open position, there is no need for a separate operation to protrude the handle to the half-open position, which is extremely convenient in terms of operation.

In addition, in the above-mentioned embodiment, the present invention is applied to an outside handle, but the present invention can also be applied to an inside handle. In this case, since the handle does not protrude into the interior of the vehicle, it does not interfere with the passengers inside the vehicle, and it is safe, and the interior space of the vehicle can be used effectively.

Furthermore, in the above-mentioned embodiment, when in the a1 lock state, the inside handle (not shown) may be released due to an erroneous operation or the like, and the release lever (5) may be rotated to the release position. The out-of-the-board device (Bl
There is a risk that the handle C31) will be in a half-open state and the vehicle will be driven with the handle C31) protruding.

In order to eliminate such a fear, it is possible to use an 11" x 11 configuration as in the second example h111 shown in FIGS. 9 to 11.

In this second embodiment, the release lever (5) in the first practical IjGi example is connected to a common shaft (4:)? Divide the board (1) with Ij into two levers, and attach the first J11 (r
An inside handle is connected to one end of the release bar (5), the upper end of an intermediate lever (9) is pivotally connected to the other end, and a connecting rod (1) is connected to the free end of the second release lever (5).
3) The lower end τ1 is connected to the bent part (+3a) i, and the outside handle device (Bl) in the first embodiment is connected only when the handle in the device similar to Bl is rotated from the half-open position to the fully open position. 2 W (middle i'z of group lever (5)
The contact piece (gt;) bent at the part is No. 1111/1.
' The nth ICC lever (5) comes into contact with the edge of the release lever (5) so that it is driven toward the release position (Fig. 11) that releases the lIi'-1 engaged state of the door lock. , in other cases, the first release lever is ': sea urchin. The other configurations are the same as those of the first embodiment.

In addition, No. 9 Hii 1 is based on Fig. 2 showing the first embodiment and No. 1
Figure 0 is the same as Figure 3, and Figure 11 is the same as Figure 4.
They are shown in correspondence with the figures.

By adopting this configuration such as the one on the flow side, the release operation inside the car can be performed independently of the release operation on the outside of the car, so that the inside and outside operations of the car in the first embodiment described above can be performed independently. This eliminates the fear that the handle on the outside of the vehicle will protrude from the door panel.

The present invention is capable of such changes and modifications.
