Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a handle structure for a sliding door of an automobile.

(Prior Art) A sliding door that opens and closes along the vehicle body is generally installed in pan-type automobiles, etc., but the conventional handle structure installed for opening and closing this sliding door is It is as shown in the front view in the figure. That is, a recess b is provided in a position close to the door frame of a sliding door (hereinafter simply referred to as a door) a, and both a handle C and a safety handle d are attached to this recess, and the door lock is released when the door is opened. I made a handle cf-FV, and
The structure is such that a safety handle d is operated to unlock the door when the door is fully open. Therefore, the conventional door handle consists of both the handle C and the safety handle d, so it is large, the manufacturing cost is high, there are many constraints on the shape, and the movement of the handle C and the safety handle d is complicated. However, it had the disadvantage of being prone to breakdowns.

(Problems to be Solved by the Invention) The present invention was made by focusing on the above-mentioned drawbacks of the conventional sliding door handle. To provide a door handle structure capable of unlocking and unlocking with only one handle and a simple mechanism without failure.

(Means for Solving the Problems) The present invention will be explained below based on the attached drawings showing embodiments.

Fig. 1 is a side sectional view of the handle structure of the present invention, Fig. 2 is a front view thereof, Fig. 3 is a rear view thereof, Fig. 4 is a sectional view taken along line A-A in Fig. 2, and Fig. 5 is a FIG. 6 is a sectional view taken along the line CC in FIG. 1 and shows the state in which the spring is installed.

In the figure, a handle 1 has a substantially rectangular front shape, and has a pair of legs 2 and 3 on the back surface near both longitudinal ends.
is provided in a protruding manner and is attached to a bracket 7 fixed to the door surface 6 via pins 4 and 5.

The extending portions of both ends of the bracket 7 in the longitudinal direction are bent toward the handle 1 side, and the legs 2 and 3 are bent at the bent portions 7a and 7 of the bracket 7.
It is rotatably mounted around pins 4 and 5 inserted parallel to the surface of the handle 1 through a bottle hole provided in b. That is, the handle 1 has a pin 4 as shown in FIGS. 4 and 5.
, 5 as support shafts, and the legs 2 and 3 as arms, which can be rotated left and right in an arc shape. Also, among the pair of legs 2 and 3, one leg 2 is extended longer than the other leg, and as shown in FIG. The lever protrudes from the surface of the door 6 and functions as a lever for unlocking when opening the door 6 inside the door 6. As shown in FIG.
The spring 8 is wound so that the spring 8 is biased in one direction (in the illustration, the extension portion 2a of the leg portion 2 is biased toward the right).

On the other hand, between the other leg 3 and the bracket bent portion 7b, a lever 9 is mounted in contact with the leg 3 and is rotatable about the pin 5 as the same support axis. This lever 9 has one end with a side surface 9
a, the protruding piece 10 is abutted on the back surface of the handle 1 and is perpendicular to the leg part 3, and the other end protrudes from the surface of the bracket 7, and this protruding part 9b is in the fully open state inside the door 6. It functions as a lock release when closing the door.

Further, on the outer periphery of the pin 5 between the lever 9 and the bracket bent portion 7b, the lever 9 is biased in a direction opposite to the biasing force direction of the leg portion 2 (in the illustration, the protruding portion 9b of the lever 9 is directed to the left). The spring 11 is wound in this manner. The biasing force of this spring 11 is set to be larger than the biasing force of the spring 8.

Further, the lever 9 is prevented from rotating due to the urging force of the spring 11 by a stopper portion 7c extending from the side end of the bracket 7 at a position where the end side surface 9a abuts the protrusion 10 of the handle 1. There is.

In addition, a protrusion piece 12 for finger rest may be provided perpendicularly to the leg part 2 on the back surface of the handle 1 near the base of the leg part 2.

(Function) Next, the function of the handle structure of the present invention having the above configuration will be explained.

That is, as shown in FIGS. 4 and 5, the handle 1 is rotated in the direction of the arrow A while guarding the projection piece 12 on the side of the back surface of the handle 1 which is in a resting state (also called a neutral state). When the lever 9 is in a stationary state, only the legs 2 and 3 rotate together with the handle 1 about the pins 4 and 5.

Then, although the leg part 3 is used only for attaching the handle 1 and does not participate in the unlocking function of the door 6, the extension part 2a of the leg part 2
As shown in Fig. 5, it rotates inside the door 6 in the direction of the arrow A' against the biasing pressure of the spring 8, and activates an interlocking mechanism (not shown) to unlock the door in the closed state. .

After releasing the lock, the biasing pressure of the spring 8 causes the fifth
It is returned to the neutral state shown in the figure.

In addition, in order to unlock the door 6 which is fully open and locked, rotate the handle 1 from the opposite side in the direction of the arrow as shown in Fig. 4. The lever 9 is pressed by the protruding piece 10 on the back side of the handle 1 against the biasing pressure of the spring 11, and rotates in the direction of the arrow ``opening'', creating an interlocking mechanism (not shown) and opening the door. Unlock the door and enable it to close. After the lock is released, the lever 9 is rotated by the biasing pressure of the spring 11 to the inhibited position by the stopper portion 7C, and the handle 1 is also returned to the neutral state shown in FIG. 4.

(Effects of the Invention) As described above in detail, according to the handle structure of the present invention, one handle 1 is provided with the unlocking function of the door in the closed state and the unlocking function of the door in the open state. Since these functions are achieved by rotating each side of the handle 1, the installation of a conventional safety handle becomes unnecessary, the handle structure becomes smaller and simpler, and the manufacturing cost becomes lower. Since the lock release function is performed separately by the handle mounting leg 2 and the lever 9, which are biased in opposite directions via the springs 8 and 11, respectively,
Each lock release function is simplified, design can be freely configured, and malfunctions are almost eliminated.
