Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a door inside handle used for opening an automobile door.

[Background Art] An inside door handle is generally attached to the inside of an automobile door, and by rotating the handle, an occupant can release the latch mechanism of the door and open the door.

However, in addition to this inside handle, the door is also equipped with an assist grip for the occupant to grasp when opening and closing the door to apply force to open and close the door.

This assist grip largely protrudes toward the inside of the door and has a large space inside the door.

Therefore, if the inside door handle and the assist grip are shared, the number of parts can be reduced, but the conventionally proposed devices in which the inside handle is attached to the assist grip have a complicated structure, poor operability, and require the occupant's hands. The structure was not designed to match the movement of the door and the opening and closing of the door.

[Object of the Invention] In consideration of the above facts, the present invention provides a door inside handle that shares the inside handle and the door assist grip, reduces the number of parts, and improves operability. It is a purpose.

[Summary of the Invention] In the door inside handle according to the present invention, an assist grip for grasping an occupant, which also functions as an armrest, is rotatably supported on an armrest protruding from the door and rotated in a direction around an axis along the front-rear direction of the door. The door latch mechanism is configured to release the door latch mechanism, the door inside handle is shared with the assist grip, and the rotation of the assist grip simultaneously releases the door latch mechanism and opens the door, thereby improving operability. .

[Embodiments of the Invention] FIG. 1 shows a perspective view of a door 10 to which the present invention is applied. In this door 10, an assist grip 14 is pivotally supported on the inner side of the inner panel 12.

As shown in FIGS. 2 and 3, this assist grip 14 has a rectangular planar shape and is attached to the inner panel 1.
It protrudes from 2 and has an opening 16 in the center,
As a result, the portion facing the inside of the vehicle can be gripped by the gripping portion 14A.
It is said that

A pair of pins 18 and 20 coaxially protrude from both sides of the assist grip 14 in the front-rear direction of the door 10. These pins 1
8 and 20 are pivotally supported on the door 10 so that the assist grip 14 can rotate around these pins 18 and 20. The rotation of the assist grip 14 is in a normal state as shown in FIGS. 1 to 3, and the grip portion 14A can be rotated by several tens of degrees in the downward direction of the vehicle (in the direction of arrow A) from this state. pin 1
A torsion coil spring 22 is interposed between the assist grip 8 and the door 10 to generate a biasing force for returning the assist grip 14 to a horizontal position. Further, the assist grip 14 is provided with a stopper (not shown) to stop it in a horizontal position.

An arm 24 protrudes from the side opposite to the grip portion 14A of the assist grip 14, and is adapted to come into contact with one end of a lever 28 which is pivotally supported on the door 10 by a pin 26 as shown in FIG. This lever 28
One end of the link 30 is pivotally supported at the other end,
The other end of the link 30 is connected to a door latch mechanism (not shown) that is attached between the door 10 and the vehicle body and holds the door closed. Lever 2
8 is a link 30 with the biasing force of a torsion coil spring 32.
While applying a tensile force to the arm 2, one end of the arm 2
It is designed to be placed within the rotation trajectory of 4, but
The link 3 receives the rotational force of the assist grip 14.
When a compressive force is applied to 0, the door latch mechanism is released and the door 10 can be opened.
A reinforcing plate 34 is embedded in the arm 24 at the contact portion of the lever 28 to reduce wear.

On the other hand, the assist grip 14 has its vehicle front end and rear end adjacent to the armrests 36 and 38, and in the state shown in FIG. It's summery. Therefore, this assist grip 14 can also be used as part of an armrest.

A lock knob 40 is provided on the inside surface of the armrest 36 and is movable in the longitudinal direction of the vehicle. As shown in FIGS. 1 and 2, the lock knob 40 is in the locked state when it has moved the maximum amount toward the rear of the vehicle, and is in the unlocked state when it has moved the maximum amount toward the front of the vehicle from this state.

When the lock knob 40 is in the locked state, the lock pin 42 protruding from the lock knob 40 is inserted into the pin receiving hole 44 formed on the side surface of the assist grip 14, so that the assist grip 14 cannot rotate around the pins 18, 20. As a result, the door latch release operation by the assist grip 14 is disabled.

Also, this lock knob 40 is the assist grip 1.
It can move in the longitudinal direction of the vehicle across slide grooves 46 and 48 formed on the inside surface of the armrest 36 and the inside surface of the armrest 36, and in the locked state shown in FIGS. It's now in a good position. This also prevents the assist grip 14 from rotating in the locked state. However, when the lock knob 40 reaches the unlocked state, the lock pin 42 comes out of the pin receiving hole 44 and also comes out of the slide groove 46 and enters only the slide groove 48, so the lock knob 40 does not interfere with the rotation of the assist grip 14.

One end of a lever 52, which is pivotally supported to the door 10 by a pin 50, is pivotally supported on the lock knob 40.
The other end of this lever 52 pivotally supports a link 54. The other end (not shown) of this link 54 is connected to a door lock device, and when the lock knob 40 reaches the unlocked state, this link 54 receives a compressive force and releases the lock device (not shown), and the door latch is released by rotation of the assist grip 14. The door can be opened by releasing the door latch by operating a doorknob (not shown) provided on the outside of the door 10.

A central portion of a release lever 58 is pivotally supported in the central portion of the lock knob 40 by a pin 56. One end of the release lever 58 is a release button 60, which is projected from the lock knob 40 toward the inside of the vehicle by the biasing force of a compression coil spring 62. When the release button 60 protrudes further toward the inside of the vehicle than the lock knob 40, the protrusion 64 on the opposite side of the release button 60 enters the hole formed in the door 10 and prevents the lock knob 40 from moving. There is. Therefore, in order to move the lock knob 40 from the locked state to the unlocked state, the occupant must push the release button 60 into the lock knob 40 and then move the lock knob 40.

Next, the operation of this embodiment will be explained.

1 and 2 show the door in the locked state, and since the assist grip 14 is prevented from rotating by the lock knob 40, the door latch mechanism cannot be released, and the door 10 is maintained in the closed state.

When the occupant opens the door 10, he or she pushes the release button 60 into the lock knob 40 and then slides the lock knob 40 toward the front of the vehicle. As a result, the lock knob 40 slips out of the slide groove 46 and enters the slide groove 48, and the lock pin 42 slips out of the pin receiving hole 44, allowing the assist grip 14 to rotate. At the same time, the link 54 receives a compressive force and releases the door lock mechanism.

Thereafter, the occupant grasps the grip portion 14A and pushes it down in the direction of arrow A, thereby rotating the assist grip 14 in the direction of arrow A. Therefore, the link 30 transmits the rotational force to the door latch mechanism,
The door latch is released. This allows door 10
can be opened, and if the assist grip 14 is pushed out to the outside of the vehicle as much as necessary, the door 10 will be opened by that amount.

When the occupant releases the grip portion 14A, the assist grip 14 returns to the horizontal position due to the biasing force of the torsion coil spring 32.

Therefore, when the occupant wants to close the door 10, he/she grasps the grip part 14A and pulls it toward the interior of the vehicle, and the door 10 is closed by a door latch mechanism (not shown). Further, when the door is to be locked, the lock knob 40 is moved toward the rear of the vehicle, and the lock knob 40 returns to the state shown in FIG. 2 and the door is locked.

In this manner, the assist grip 14 can release the door latch mechanism simply by rotating it around the axis, allowing the occupant to open the door with an extremely simple operation. Particularly in this embodiment, when the assist grip 14 is operated in the door opening/closing direction, the door latch is also released at the same time, so that the door can be opened and closed in a very natural manner. Furthermore, since the assist grip 14 has a large gripping portion 14A, the occupant can apply a door opening/closing force with reliable operation.

Further, in the above embodiment, the lock knob 40 can be moved by pressing the release button 60, so that the door lock state will not be released by careless operation.

[Effects of the Invention] As explained above, in the door inside handle according to the present invention, the assist grip for grasping an occupant is pivotally supported on the door, and the door latch mechanism is released by rotation of the assist grip, so that the number of parts is reduced and This has an excellent effect of improving operability for the occupants.
