DETAILED DESCRIPTION OF THE INVENTION 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.

The outside handle attached to the outer panel of a conventional automobile door (hereinafter referred to as the door panel) is the one used in the 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.

The object of the present invention is to provide a door handle device for an automobile that solves these problems.The feature of the present invention is to apply a push-lock/push-release mechanism so that the door handle device can be closed when the handle is not in use. , the handle is in a closed position that closes the finger insertion recess formed in the case, and if you want to operate the handle, push it in slightly and the handle will protrude to the usable position on its return trip, and from this state. By releasing the handle, the handle is then returned to its original closed position.

The present invention will be described below based on embodiments shown in the accompanying drawings.

A case 3 made of hard synthetic resin or metal is fixed thereto.

A handle main body 5 having a horizontally long rectangular front shape is pivotally attached to the case 3 with a shaft 4 extending in the left-right direction in FIGS. 2 to 4.

As shown in FIG. 6, the handle body 5 has an outer surface that is flush with the outer panel 1 and a closed position a that closes the recess 2, and a lower end that protrudes outward from the recess 2 and is located between the recess 2 and the closed position a. It moves to a half-open position b that secures a space in which a hand can be inserted, a fully open position c where the lower end is further expanded than the half-open position b, and an operating position d where the lower end is slightly recessed into the recess 2 from the closed position a. It is possible.

A relatively weak coiled spring 6 serving as a biasing means is wound around a suitable position in the middle of the shaft 4, and one end 6a of the spring 6 is secured to the case 3, and the other end 6b is secured to the handle body 5, respectively. Due to this coiled spring 6, the handle body 5 is always biased clockwise in FIGS. 5 to 7.

A release lever 8 serving as a direction changing mechanism is pivotally attached to the upper center of the back surface of the case 3, with a shaft 7 facing in a direction perpendicular to the shaft 4 of the handle body 5. The release lever 8 is rotated clockwise in FIG. The upper end of a vertical rod 9 whose lower end is linked to a door lock (not shown) is connected to its free end 8c.

As clearly shown in FIG. 4, there is a flange portion 8a facing forward at the upper left side of the pivoting portion of the release lever 8.
In addition, an engaging portion 8b is formed on the right side, and
When the handle body 5 is in the half-open position b, the free end of the inwardly facing protrusion 5a formed on the upper edge of the left side of the handle body 5 comes into contact with this flange 8a, and the handle body 5 is in the half-open position b. When the door is rotated from the fully open position c to the fully open position c, the release lever 8 is rotated counterclockwise in FIG. 4 with the protrusion 5a in contact with the flange 8a, and the rod 9 is pushed down to release the door lock. It is now possible to operate it. 3b comes into contact with the hanging piece 8d of the release lever 8 and releases the release lever 8.
This is a stopper that restricts clockwise rotation.
As described above, the handle H is composed of the handle body 5 and the release lever 8.

The base of an actuating lever 11, which is an actuating member, is pivotally attached to the upper center of the back surface of the case 3 with a shaft 7.

On the rear surface of the actuating lever 11, there is an engaging portion 1 facing rearward.
1a is provided protrudingly, and at the lower part of this engaging portion 11a,
The engaging portion 8b of the release lever 8 can come into contact with it. Further, a protruding piece 5b protruding from the central inner surface of the handle main body 5 can come into contact with the engaging portion 11b at the intermediate lower edge of the operating lever 11.

A coil spring 12 stronger than the coil spring 6 is wound around the shaft 7. One extending end 12a of the coil spring 12 is engaged with the convex portion of the case 3, and the other extending end 12b is engaged with the upper edge of the operating lever 11. 11 is always biased clockwise in FIG.

A guide groove 13 having a substantially triangular front shape is cut in the front surface of the free end of the actuating lever 11 . This guide groove 13 has a bottom side 13b having a downwardly U-shaped bent portion 13a at the center in FIG.
The ascending hypotenuse 13c stands upward from the right end of the base 13b, and the descending hypotenuse 13d extends from the upper end of the ascending hypotenuse 13c to the left end of the base 13b. The depth gradually becomes shallower, and a step 13e is formed between the upper end of the ascending oblique side 13c and the upper end of the descending oblique side 13d, as shown in FIG.

Reference numeral 14 denotes a locking lever, which is a locking member and is oriented substantially in the vertical direction, and its lower end is pivotally attached to the lower back surface of the case 3 with a shaft 15.

Reference numeral 16 denotes a coiled spring wound around the shaft 15 between the tip of the shaft 15 and the locking lever 14, one end 16a of which is connected to the tip of the shaft 15 and the other extending end 16b. are respectively locked to the lower end and the side edge of the locking lever 14, and constantly bias the locking lever 14 clockwise in FIG. It's pressed down.

A pin 17 pointing inward is provided at the upper end of the locking lever 14, and the tip of this pin 17 is connected to the guide groove 1.
3, and according to the operation of the operating lever 11,
It circulates along the guide groove 13 as described later.

In this way, the operating lever 11, the guide groove 13, the locking lever 14, the pin 17, etc. form a push-lock/push-release mechanism A that projects the handle body 5 to the half-open position and returns it to the closed position. .

Next, the operation and handling of the above-described embodiment will be explained with reference also to FIGS. 9 to 12.

The handle body 5 is in the closed position a shown in solid line in FIG.
, the operating lever 11 is in the first position a', which is the locked position shown in FIGS. 4 and 9.

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 11a, 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. It prevents it from being rotated.

From this state, when the handle body 5 is pushed to the operating position d shown by the imaginary lines in FIGS. 6 and 7, the handle body 5
The engaging portion 11b is pushed up by the protruding piece 5b, and the operating lever 11 is placed in the second position b', which is the push position shown in FIG.

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 biased counterclockwise in FIG. 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. When the pin 17 descends over the step 13e and reaches the upper end of the oblique side 13d, the locking lever 14 returns to its original upright state due to the compressive biasing force of the coiled spring 16 in the direction of the shaft 15, and the pin 17
It 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.

At this time, the protruding piece 5a of the handle body 5 moves downward to the flange part 8a of the release lever 8, and the engaging part 11a of the operating lever 11 moves downward to the release lever 8.
are in contact with or close to the engaging portions 8b, 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 oblique side 13d as shown by the solid line in FIG. 12, and since the locking lever 14 is always urged counterclockwise in FIG. Immediately move slightly to the left and move to the 12th
As shown by the imaginary line in the figure, it comes into contact with the lower left corner of the right half of the bottom side 13b 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 urging force of the coiled spring 12, and returns to the first position shown in FIG.
a', the pin 17 is once removed upward from the position shown by the imaginary line in FIG. 12, and returns to the position shown in FIG. 9.

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, the handle body 5 can be
Due to the operation of the push release mechanism, the closed position a
By pushing the door from the half-open position B to the operating position d, the door will protrude to the half-open position b on the return trip, and by lifting the door from the half-open position b to the fully open position c to release the door lock, the door will move to the closed position a on the return trip. Can be rotated back up to
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.

As is clear from the above, according to the present invention, since there is no recess or protrusion for opening the door when the door is closed, turbulence in air flow during high-speed running is significantly reduced, and running resistance is reduced. This also suppresses wind noise and improves the appearance quality.

Furthermore, since there are no recesses or protrusions, clothes will not get caught on the vehicle, making it extremely safe for the vehicle.

Furthermore, when opening the door, simply pushing the handle once will cause the handle to protrude to a position where it can be operated, and in that state, simply operating the handle to open the door will automatically return the handle to its original closed state. , the door opening operation is easy.

Moreover, if the outer surface of the handle is smoothly continuous with the case so as to be substantially flush with the door panel as in the embodiment, the running resistance characteristics and the appearance quality are further improved.

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 small and operate smoothly, but the amount of mechanism protruding from the case 3 will be small, and the space inside the door will not be compressed. can contribute to the expansion of

Furthermore, if the handle H is divided into the handle body 5 and the release lever 8 as in the embodiment, and the respective spindles 4 and 7 are arranged so as to face perpendicularly to each other, the amount of protrusion from the case 3 can also be reduced. This reduces the amount of space inside the door and prevents the space inside the door from being compressed.
