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 gripping the vehicle, which the occupant grips when opening and closing the door to apply force to open and close the door.

This assist grip protrudes greatly 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 devices that have been proposed in the past, in which the inside I handle can be attached to the assist grip, have a complicated structure and poor operability. The structure did not match the movement of the occupant's hands and the movement of opening and closing the door.

[Purpose of the Invention] The present invention takes into account item 1-1, and provides a door inside handle that shares the inside handle and the door assist I/grip, reduces the number of parts, and improves operability. That is the purpose.

[Summary of the invention] In the door inside handle related to the unreleased Ij1, the driver i-
- The grip is pivoted to the door, and the door latch mechanism can be released by rotating the assist grip.The door inside handle is shared with the assist grip, and the door can be opened by rotating only one assist grip. (7) It is designed to improve operability.

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

As shown in FIG. 2.3, this assist grip 14 has a calyx-shaped planar shape and protrudes from the inner panel 12.
It has an opening 16 in the center, so that the part facing toward the inside of the vehicle serves as a grip part 14A.

A pair of bins 18 and 20 protrude coaxially from both sides of the assist grip 14. these bins 18
．． 20 is pivotally supported on the door lO so that the assist grip 14 can rotate around this pin 18.20. The rotation of the assist grip 14 is in a normal state as shown in FIGS. 1 to 3, and from this state, the grip portion 14A can be rotated by several tens of degrees in the downward direction of the vehicle (in the direction of the arrow). A torsion coil spring 2 is installed between the pin 18 and the door lO.
2 is interposed to generate the old force for returning the assist grip 14 to the horizontal state. Further, the assist grip 14 is provided with a stopper (not shown) in order to stop at the horizontal position ♂l.

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 by a bottle 26 to the door IO, as shown in FIG. One end of a link 30 is pivotally supported at the other end of this lever 28, and the other end of this link 30 is provided with a door latch mechanism (not shown) that is held between the door 10 and the vehicle body and holds the door in the closed 1F state. (omitted). The lever 28 applies a tensile force to the link 3° by the biasing force of the torsion coil spring 32, and its one end is placed within the rotational trajectory of the arm 24, but it receives the rotational force of the assist grip 14. When a compressive force is applied to the link 30, 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 bar 8-28 to reduce wear.

On the other hand, the assist grip 14 has both front and rear ends adjacent to the armrest 36, 38, and in the state shown in FIG.
It forms the same surface as 6.38. 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. This lock knob 4
As shown in FIG. 1.2, the state in which the vehicle has moved the maximum amount toward the rear of the vehicle is the locked state, and the state in which the vehicle has moved the maximum amount toward the front of the vehicle from this state is the unlocked state.

When the lock knob 40 is in the locked state, the lock bin 42 protruding from the lock knob 40 is attached to the assist grip 1.
The assist grip 14 is inserted into the pin receiving hole 44 formed on the side surface of the pin 18.20, thereby making it impossible for the assist grip 14 to rotate around the pin 18.20, and as a result, the door latch release operation by the assist grip 14 becomes impossible. It is located.

Further, this lock knob 40 can be moved in the longitudinal direction of the vehicle 1114 across slide grooves 46 and 48 formed on the inner surface of the assist grip 14 and the inner surface of the armrest 36, as shown in FIG. 1.2. In the low 2 state, the slide grooves 46 and 48 are interposed together.As a result, in the locked state, the assist grip 1
Rotation of 4 is blocked. However, when the lock knob 40 reaches the unlocked state, the lock pin 40 pulls out from the pin receiving hole 42, pulls out from the slide groove 48, and enters only the thin plate 46, so the lock knob 40 prevents the assist grip from rotating 140 degrees. Never.

One end of a lever 52 is pivotally supported on the lock knob 40, and the lever 52 is pivotally supported on the door 10.
The other end 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 to release a locking device (not shown), and enables the door latch release operation by rotation of the assist grip 14 and the door latch release action by operating a door knob (not shown) provided on the outside of the vehicle of the door lO, so that the door can be opened. It has become.

A release lever is located in the center of the lock knob 40 with a pin 56.
58 is pivotally supported. One end of this I/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.
+f2. Therefore, in order to move the release button 40 from the locked state to the unlocked state, it is necessary to 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.

FIG. 1.2 shows the door in the locked state, and since the assist clip 14 is prevented from rotating by the lock knob 40, the door latch mechanism cannot be released, and the door IO is maintained in the closed state.

If the occupant wants to open the door lO, press the release button 6.
After pushing 0 into the lock knob 40,
slide it toward the front of the vehicle. As a result, the lock knob 40 is pushed out of the slide groove 48 and inserted into the slide groove 46, and the lock pin 42 is pulled out of the bottle 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 rider i grasps the grip part 14A and pushes it down in the direction of arrow A, causing the link 30 to transmit its compressive force to the door latch mechanism, and the door latch is released. As a result, the door 10 can be opened, and the occupant can further push the assist grip 14 to the outside of the vehicle to open the door 10 by the required angle.The occupant releases the grip on the grip part 14A, and the assist grip 14 is released by the torsion coil spring. With the urging force of 32, it returns to the water f position again.

Therefore, when the occupant closes the door 10, the grip portion 14
When A is grasped and pulled toward the indoor side, 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 way, the door latch is released by simply pushing down the assist grip 14 in the direction of the vehicle F, so the occupant can open the door with an extremely simple operation. Particularly in this embodiment, the door latch is released at the same time when the assist grip 14 is operated in the door opening/closing direction, so the door can be opened and closed with extremely natural movements. Furthermore, since the assist grip 14 has a large gripping portion 14A, the occupant can apply the door opening/closing force with a reliable motion. ix - Furthermore, in the above embodiment, the lock knob 40 is movable by pressing the release button 60, so that the door lock state will not be released by an inadvertent operation.

Note that the present invention is not limited to the embodiments 1 and 2, but can also be used with the axis of the assist grip 14 tilted or vertical.

[Effects of the Invention] As explained above, the door inside handle according to the present invention has one passenger grip assist system which pivots the grip to the door,
Since the door latch mechanism is released by rotation of the assist grip, the number of parts is reduced and the operability for the occupant is improved, which is an excellent effect.
