Description

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. Purpose of the Invention The present invention has been made by focusing on such conventional problems, and improves aerodynamics by keeping the recess in the handle attachment part closed during the running state without impairing the operability of opening and closing the door. An object of the present invention is to provide a door handle device for an automobile that has improved characteristics, significantly reduces wind noise generation, and improves appearance quality.

d Structure of the Invention The present invention is characterized in that the recess for inserting a hand, finger, etc. in the handle case is closed by the door lock release handle and the push lever disposed at the bottom of the handle, and the recess in the push lever is closed. The handle is made to protrude from the recess when the handle is inserted into the handle, thereby securing a space into which the fingers can be inserted.

e Embodiment FIGS. 1 to 9 are diagrams showing an embodiment of the present invention.

In each figure, 1 is a door handle, and 3 is a handle case attached to the door panel DP, in which a recess 3a for inserting a hand or finger is formed. 5 indicates a push lever. In normal conditions, the door handle 1 and the push lever 5 are arranged vertically on substantially the same plane and close the recess 3a. Further, the door handle 1 is arranged on substantially the same plane P together with the door panel DP and the handle case 3.

In FIG. 2, 15 is an A lever, 17 is a B lever, 11 and 13 are a door handle and a return spring for the B lever, respectively, and 25 is a sliding pin installed on the rear surface of the push lever 5. Figures 2 and 3
In the figures and FIG. 4, the door handle 1 has an integral a-arm 2, the a-arm 2 is pivotally supported on a hinge shaft 10 fixed to the panel, and the A-lever 15 is attached to the tip of the a-arm 2 with a pin. It is pivoted by 28. The A lever 15 is suspended from the pin 28, the middle bent piece 15a is provided with a first elongated hole 16, the lower part is provided with a second elongated hole 18, and a stopper pin 20 is fixed to the panel. the second long hole 18
The movement of the A lever is restricted by inserting it into the A push lever 5 is provided on the lower inner side of the door handle 1, and the rear end of the push lever 5 has an inclined portion 5a that engages with the first elongated hole 16 of the A lever.
is formed.

As shown in FIG. 6, the push lever 5 can also be slid in a direction substantially perpendicular to the surface of the door panel DP by means of a sliding pin 25 penetrating the bottom wall 3b of the handle case 3. A return spring 19 is inserted between the push lever 5 and the push lever 5 to constantly bias the outer surface of the push lever 5 so that it is substantially flush with the outer surface of the door handle 1.

The door handle 1 further has an integral second b-arm 4, which is pivotally supported on a hinge shaft 10 and is rotated by rotation of the door handle 1, as shown in FIG.
The tip can be engaged with the B lever 17.

The B lever 17 is attached to the pivot pin 9 as shown in FIG.
It is rotatable about the door lock, and a rod (not shown) for driving the door lock is pivotally supported in the pin hole 14 at the other end. Further, as shown in FIG. 7, the B lever 17 is always urged to rotate upward by the spring 13.

As shown in FIGS. 2 and 8, the door handle 1 has a spring 11 that biases the exposed outer surface of the handle case and the outer surface of the door handle so that they are always flush with each other.

FIG. 9 is a sectional view showing the function of the door handle. When the door is closed, the door handle 1 is in a state P where it is almost flush with the push lever 5, but the push lever 5 shown in FIG. When opening the door by manually pressing it inward (rightward in the figure), the inclined part 5a of the push lever engages with the first elongated hole 16 of the A lever 15, and the A lever 15
is pushed down, so that the a-arm 2, which is pivoted by the common pin 28, is pushed down about the hinge shaft 10, and the door handle 1 is slightly rotated outward (clockwise in FIG. 3). The position is Q as shown in FIG. 9, and the gap between P and Q becomes the space for the hand.
In this state, the position of the A lever 15 shown in FIG.
has become an intermediate position. When the handle space between P and Q is reached and the door handle 1 is fully opened to the R position shown in FIG. 9, the A lever 15 in FIG. Engage and stop. In this state, the tip of the B-arm 4 shown in FIG. A rod pivotally supported at the end 14 releases the lock.

f. Effects of the Invention Since the present invention is constructed as described above, (1) Since the door handle and push lever that close the recess of the handle case are substantially flush with the surface of the door panel, air resistance during driving is reduced. It was possible to improve aerodynamic characteristics and reduce wind noise.

Additionally, the appearance quality around the handle has been improved.

(2) The sliding pin of the push lever passes through the bottom wall of the handle case, making it possible to slide the push lever in the axial direction of the sliding pin, thereby reducing the gap formed between the push lever and the handle case. The appearance quality around the door handle has been further improved.

(3) The push lever and the door handle, which rotates when the push lever slides, are housed compactly inside the handle case, so the internal structure of the handle case is simple and the thickness of the door handle device can be made thin. We were able to.
