DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a door handle device for an automobile, which is provided on a door of an automobile and is used to open the door.

b. Prior art The outside handle attached to the outer panel of a conventional automobile door (hereinafter referred to as the door panel) is described in Automotive Engineering Complete Book Volume 13 "Passenger Car Body"
(Sankaido edition) As shown on page 133, the handle always protrudes from the surface of the door panel, and at key points on the door panel, there is a space at the bottom of the handle that allows you to insert your hand inside. A recess is formed.

The presence of such protrusions (handles) and recesses can cause turbulence in the airflow when the car is running at high speeds, increasing running resistance, producing wind noise, and causing unsightly appearance. It has some drawbacks, such as its poor appearance.

c. Object of the Invention The object of the present invention is to provide an automobile door handle device that solves the above-mentioned problems.

d. Structure of the Invention The present invention is characterized by applying a push-lock/push-release mechanism so that when the handle is not in use, the handle is in a closed position that closes the finger insertion recess formed in the case. When you want to operate it, push the handle slightly and it will protrude to the usable position on its return trip, then release the handle from this state and the handle will return to its original closed position. On the other hand, when the door lock is locked, the handle is restrained in the closed position and cannot be pulled out, and the restraint lever is designed such that the restraint is released only when the door lock is unlocked, and the handle can be operated. This is because we have established

The push release mechanism A is located at an engagement position in which the handle H is held in the closed position.

Next, the operation and handling of the first embodiment will be explained.

When the door lock is unlocked, the restraint lever B is located in the disengaged position as shown in FIGS.
The operation of the push release mechanism A is not hindered in any way.

The handle body 5 is in the closed position a shown in solid line in FIG.
4 and 9, the actuating lever 11 is
It is located at the first position a', which is the lock position shown in the figure.

At this time, due to the biasing force of the coiled spring 6, the protruding piece 5b of the handle body 5
b and attempts to push up the engaging portion 11b, but the force exerted by the coiled spring 12 to push down the engaging portion 11b of the actuating lever 11 is greater, so the actuating lever 11 stops at this position. There is.

At this time, the pin 17 is engaged with the upper left corner of the bent portion 13a of the bottom side 13b of the guide groove 13 in FIG. This prevents it from being rotated.

From this state, when the handle body 5 is pushed to the operating position d shown by the imaginary line in FIGS. This results in the second position b', which is the push position shown in the figure.

At this time, the pin 17 is inserted into the bent portion 1 of the bottom side 13b of the guide groove 13, as shown by the solid line in FIG.
3a, and the locking lever 14 is constantly urged in the counterclockwise direction in FIG. 10 by the coiled spring 16, so that the guide is immediately removed as shown by the imaginary line in FIG. Groove 13
It comes into contact with the left end of the bottom side 13b and stops.

When the hand is released from the handle body 5 in this state, the free end of the operating lever 11 is pushed down by the biasing force of the coiled spring 12. Then, the pin 17 slides relatively upward along the ascending oblique side 13c of the guide groove 13. At this time, the pin 17
As the locking lever 14 climbs up, it is pushed forward (to the right in FIG. 5), and the upper end of the locking lever 14 is slightly tilted forward. Pin 17 is step 13e
When reaching the upper end of the descending oblique side 13d, the locking lever 14 returns to its original upright state due to the compression biasing force of the coiled spring 16 in the direction of the axis 15, and the pin 17
is deeply engaged with the upper end of the downward oblique side 13d.

When the pin 17 engages with the upper end of the downward oblique side 13d, the operating lever 11 becomes the third position c', which is the release position shown in FIG. 17, and the operating lever 11 stops in that state.

Furthermore, while the actuating lever 11 reaches the third position c' from the second position b', the protruding piece 5b is pushed down by the engaging portion 11b of the actuating lever 11, and the handle body 5 changes as shown in FIG. It is rotated to the half-open position b shown by the line.

At this time, a space into which a hand can be inserted is formed between the lower end of the handle body 5 and the case 3.

Also, at this time, the protruding piece 5a of the handle body 5 moves downward and touches the flange part 8a of the release lever 8.
The engaging portion 11a of the actuating lever 11 contacts or approaches the engaging portion 8b of the release lever 8, respectively.

From this state, when you insert your hand under the handle body 5 and pull the handle body 5 up to the fully open position c shown by the imaginary line in FIG. , the release lever 8 is the first
The door lock can be released by rotating clockwise in FIG. 1 and pushing down the rod 9. At the same time, the engaging part 11a of the operating lever 11 is pushed up by the engaging part 8b of the release lever 8 and rotated clockwise against the biasing force of the coiled spring 12, and the guide groove 13 is rotated upward. Move to.

At this time, the pin 17 relatively descends along the downward oblique side 13d of the guide groove 13.

When the handle body 5 reaches the fully open position c, the operating lever 11 is moved to the fourth push position, as shown in FIG. 12, which is approximately the same as the second position a' shown in FIG.
The position becomes d′.

At this time, the pin 17 is removed downward from the downward oblique side 13d as shown by the solid line in FIG. 12, and the locking lever 14 is always urged counterclockwise in FIG. 12 by the coiled spring 16. As a result, it immediately moves slightly to the left and comes into contact with the lower left corner of the right half of the bottom side 13b, as shown by the imaginary line in FIG. 12, and stops.

In this state, when you release your hand from the handle body 5, the operating lever 11 rotates slightly counterclockwise due to the biasing force of the coiled spring 12 and returns to the first position a' shown in FIG. once moves upward from the position shown by the imaginary line in FIG. 12, and then returns to the position shown in FIG.

Further, the handle main body 5 is rotated back to the original closed position a by the return rotation force of the coiled spring 6, and the state shown in FIG. Stop at.

In this way, when the door lock is unlocked and the restraining lever B is in the release position, the handle body 5 is pushed from the closed position a to the operating position d by the operation of the push lock/push release mechanism A. As a result, on the return trip, it protrudes to the half-open position b, and by pulling it up from the half-open position b to the fully open position c and releasing the door lock, it can be rotated back to the closed position a on the return trip. You can repeat it as many times as you like.

Also, when the handle body 5 is pushed from the half-open position b to the operating position d without opening it to the fully open position c, the handle body 5
Similarly to the case where the handle body 5 is opened to the fully open position c, the operating lever 11 and pin 17 return from the state shown in FIG. 11 to the state shown in FIG. 12, and then return to the state shown in FIG. returns to the closed position a.
However, in this case, the door lock release operation is not involved.

Next, the handle body 5 is in the closed position a, and the release lever 8, the operating lever 11, and the locking lever 14
When the door lock is locked with the lock levers B in the positions shown in FIG. 9, the restraining lever B moves to the engagement position shown in FIG. 13 by the actuation of the rods 27, 24, etc. described above.

In this state, when the handle body 5 is pushed to the operating position d, the engaging portion 11b is pushed up by the projection 5b, and the operating lever 11 is moved to the second position as shown in FIG. 14, as in the case shown in FIG. 10. b′, but
At this time, the engagement between the projection 14a of the locking lever 14 and the stopper 21a of the second lever 21 prevents the locking lever 14 from rotating in the counterclockwise direction in FIG. Even if the pin 17 is relatively removed downward from the bent portion 13a of the bottom side 13b of the guide groove 13, the pin 17 does not reach the position shown by the imaginary line in FIG. 10, but maintains the state shown by the solid line in FIG. 14. do.

After that, when you release your hand from the handle body 5, the operating lever 11 is rotated counterclockwise in FIG.
7 immediately engages with the bent portion 13a of the guide groove 13,
Since it immediately returns to the state shown in Fig. 13, the handle body 5 only returns to the closed position a, but does not open to the half-open position b.

Therefore, when the door lock is unlocked, the handle body 5 cannot be opened no matter how many times the handle body 5 is pushed into the operating position d.

In addition, the door lock is unlocked, the handle body 5 is opened to the half-open position b, and the operating lever 1
1. When the door lock is locked with the other members in the position shown in _FIG . By pushing up, the handle body 5 is moved to the closed position a, and at the same time or with a slight time difference, the stopper 21a of the second lever 21 engages with the upper edge of the protruding piece 14a, and as shown in FIG. state.

Therefore, when the door lock is locked while the handle body 5 is in the half-open position b, the handle body 5 is returned to the closed position a and then restrained in that position.

FIG. 15 shows a second embodiment of the invention.

In this second embodiment, the restraining lever B' is constituted by a single lever 28 pivotally mounted on the shaft 7;
A pin 29 protrudes from the rear at the tip of an arm 28a extending upward from the free end of the lever 28.
A first contact portion that contacts the actuating lever 11 with
B ₁ ', and has a pin 30 protruding from the rear end of the free end of the lever 28 to form a second abutting part B ₂ ' that abuts the protruding piece 14a' protruding from the locking lever 14.

The other configurations are the same as those of the first embodiment, and are given the same reference numerals as in the first embodiment.

In this second embodiment, the first contact portion B ₁ ′ and the second contact portion B ₂ ′ of the restraint lever B′ rotate together around the shaft 7, as shown by the solid line in FIG. It operates in the same manner as in the first embodiment, except that it moves to the engaged position shown by and to the disengaged position shown by the imaginary line.

f. Effects of the Invention As is clear from the above, according to the present invention, when the door lock is locked, the movement of the push lock/push release mechanism is restrained by the restraining lever, thereby restraining the handle in the closed position and unlocking the door lock. Sometimes, the above-mentioned restraint is released and the push-lock/push-release mechanism operates as intended, so if the door lock is locked when parking, etc., the handle can be pulled out to the half-open position and tampered with. In addition, if the door lock is locked with a knob etc. when the car is running, the handle will not protrude from the door surface, reducing air resistance when the car is running. This is significant because it can reliably prevent the generation of noise and the danger of pedestrians' clothes being caught by the protruding handle.

Also, even if you forget to return the handle from the half-open position to the closed position, you can lock the door.
The push-lock push-release mechanism is constrained to hold the handle in the closed position, resulting in
Since the handle can be returned to the closed position at the same time as the lock is locked, it is safe even if the handle is left in the half-open position.

Therefore, if you notice that the handle protrudes to the half-open position while driving, you do not have to perform complicated operations such as stopping the car, opening the door, and returning the handle to the closed position from outside the car. In both cases, the handle returns to the closed position conveniently by simply locking the door lock using a knob or the like from inside the vehicle while the vehicle is in motion.

In the above-mentioned embodiment, the push-lock/push-release mechanism A is made up of the operating lever 11 having the guide groove 13, the locking lever 14 having the pin 17 that engages with the guide groove 13, etc. This mechanism is not limited to this embodiment; for example, it may be a mechanism similar to a known push-lock/push-release mechanism used in push-button switches and the like.
However, if the structure is as shown in the example, not only will it be compact and operate smoothly, but the amount of mechanism protruding from the case 3 will be small, so the space inside the door will not be compressed, and the interior space will be reduced by making the door thinner. can contribute to the expansion of

Furthermore, as in the embodiment, if the handle is divided into the handle body 5 and the release lever 8, and the respective support shafts 4 and 7 are provided so as to be orthogonal to each other, the case 3
The amount of protrusion from the door is reduced, which prevents the space inside the door from being compressed.
