[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an inside handle lock device for an automobile door according to the present invention will be described below with reference to FIGS.

FIGS. 1 and 2 show an embodiment according to the first invention. A latch portion 6 has a handle lever 7 for switching between a door open position and a door closed position, and a door lock position. / A lock lever 8 for switching the unlock position is provided.
It is supported so as to be rotatable around 0, 11 as a fulcrum. The handle lever 7, which is a substantially U-shaped plate-like member, is supported by a pin 10 near the center, one operating rod 12 is connected to one end, and the upper end of the connecting rod 13 is connected to the other end. Have been. An elongated hole 14 in the vertical direction is provided at the lower end in the drawing of the connecting rod 13, and a slide pin 15 fixed to the lock lever 8 passes through the elongated hole 14, and
5 is slidable using the elongated hole 14 as a guide. As a result, the connecting rod 13 functions as a connecting member that enables the interlock between the handle lever 7 and the lock lever 8. However, depending on the positional relationship between the elongated hole 14 and the slide pin 15, as described later, the handle rod 7 And the lock lever 8 do not interlock, that is, the inside handle 2
An idle region is formed in which the operation of the door 1 and the lock / unlock of the door 1 are not interlocked.

On the other hand, the other end of the operating rod 12 is connected to the inside handle 2 having a mechanism for opening the door at the same time as unlocking the door by operating the inside handle 2 while the door is locked, a so-called override mechanism. As shown in FIG. 1A, the inside handle 2 is pushed from a normal neutral position (corresponding to a door closing position to be described later) indicated by a solid line to the outside of a vehicle compartment indicated by a dashed line (to be described later). Switching operation to lock position),
A pull-out operation (switching operation to an unlock / door open position, which will be described later) can be performed toward the vehicle interior as indicated by a broken line. The above-described neutral position of the inside handle 2 is a basic position at which the inside handle 2 automatically returns by releasing the hand from the handle even during or after the pushing operation and the pulling operation. Then, since the inside handle 2 on which the desired operation has been performed rotates about the shaft 2a supported on the door panel side, the operation rod 12 moves in the axial direction indicated by the arrow 16 and the handle lever 7 is moved to the arrow 17 Rotate as shown. Further, the rotation of the handle lever 7 moves the connecting rod 13 in the vertical direction.
The lock operation unit 9 is moved up and down (arrow 18) to engage with the switch, and the switching operation of the lock position / unlock position is performed. That is, when the inside handle 2 is in the normal neutral position, the lock lever 8 is at either the lock position or the unlock position, but the handle lever 7 is at the door closed position and the door is kept closed. Therefore, such a state is hereinafter also referred to as a door closed position. When the inside handle 2 is pushed in from the door closed position, the lock lever 8 rotates clockwise while the door closed state is maintained, and the latch portion 6 switches to the locked position (hereinafter, such a state is referred to as the locked position). ). Further, when the inside handle 2 is pulled out from the door closed position, the lock lever 8 rotates counterclockwise, the latch portion 6 switches from the lock position to the unlock position, and the handle lever 7 switches to the door open position. Thus, the door can be opened (hereinafter, such a state is referred to as an unlock / door open position).

The relative movable range of the elongated hole 14 provided on the lower end of the connecting rod 13 and the slide pin 15 provided on the lock lever 8 is linked to the inside handle 2, the operating rod 12 and the handle lever 7. And a region in which the lock lever 8 is switched to the lock position (hereinafter referred to as a lock operation region) and a region in which the lock lever 8 is similarly switched to the unlock / door open position in conjunction with the handle lever 7 (hereinafter referred to as the unlock operation region). ) And an idle region in which the lock lever 8 does not interlock with the handle lever 7.

The lock operation area is the inside handle 2
Of the connecting rod 1 by operating the handle lever 7 from the door closed position to the locked position.
3 is a region where the lock lever 8 is pushed downward and moved, and the slide pin 15 abutting on the upper end of the elongated hole 14 is further pushed down to rotate the lock lever 8 clockwise. In this region, the lock operation unit 9 that engages with the lock lever 8
Is pulled down to the lock position indicated by the solid line in FIG. 1A, and the lock mechanism of the latch unit 6 functions. In this region, even if the handle lever 7 is rotated, the latch that engages with the striker does not operate, and the door is kept closed.

In the unlocking operation area, the connecting rod 13 is lifted upward and moved by the rotation of the handle lever 7 from the door closed position to the unlocked / door open position. This is an area in which the slide pin 15 abutted is pulled up to rotate the lock lever 8 counterclockwise. In this region, the lock operation portion 9 that engages with the lock lever 8 is pulled up to the unlock position indicated by the broken line in FIG. 1A, so that the lock function of the latch portion 6 is released. When the handle lever 7 is switched to the unlocked / door open position, the engagement of the latch with the striker is released by the action of the handle lever 7 as in the related art, so that the door can be opened.

The idle region is located between the lock operation region and the unlock operation region, in other words, within a predetermined operation range from the neutral position of the inside handle 2 in the pushing operation direction and the pulling operation direction. For example, as shown in FIG. 1B, the upper end and the lower end of the elongated hole 14 are areas where the connecting rod 13 can freely reciprocate without contacting the slide pin 15. Therefore, in this area, even if the handle lever 7 rotates, the connecting rod 13 simply reciprocates up and down, and the lock lever 8 to which the slide pin 15 is fixed has stopped at the lock position or the unlock position. The switching operation of the lock operation unit 9 is not performed in conjunction with the handle lever 7. That is, in this idle region, although the door can be opened and closed by turning the handle lever 7, it is not linked to the switching operation of the door lock mechanism by the lock lever 8.

Hereinafter, the operation of the above-mentioned latch portion 6 will be described together with the operation of the inside handle 2 having the override mechanism. The inside handle 2 is normally kept at the door closed position (neutral position) by the action of the spring 19, and when the inside handle 2 is pushed from the door closed position to the locked position, the operating rod 12 is pushed out and the handle lever 7 is pushed.
Rotate clockwise to lock position. As a result, the lock lever 8 also rotates toward the lock position in conjunction with the handle lever 7, so that the lock operating portion 9 engaged with the lock lever 8 is pulled down, and the latch portion 6 of the door is locked and provided outside the vehicle compartment. The door cannot be opened by operating the outside handle (not shown). When the inside handle 2 is released from the handle after the lock operation is completed, the inside handle 2 receives the bias of the spring 19 provided at an appropriate position of the inside handle 2, so that the inside handle 2 automatically returns to the door closed position from the locked position. Accordingly, even if the handle lever 7 rotates to the door closing position,
The slot 14 does not come into contact with the slide pin 15 at the lock position because it belongs to the idle area, and therefore,
The locked state of the lock operation unit 9 is maintained.

Next, when the inside handle 2 is operated to be pulled out from the door closed position (neutral position) to the unlock / door open position, the operating rod 12 is retracted, and the handle lever 7 is turned to the unlock / door open position. And rotate counterclockwise. As a result, the lock lever 8 also rotates toward the unlock position via the connecting rod 13 in conjunction with the handle lever 7, so that the lock operating portion 9 engaged with the lock lever 8 is pulled up, and the latch portion 6 of the door is unlocked. When the handle is switched to the locked state, the engagement of the latch and the striker is released by the rotation of the handle lever 7, and the door is opened. When the lock lever 8 and the lock operation unit 9 are in the unlock position, even if the inside handle 2 is operated from the door closed position to the unlock / door open position, the relative positional relationship between the slot 14 and the slide pin 15 is maintained. Is in the idle region, only the door opening operation is performed, and the lock mechanism of the latch portion 6 of the door is not switched from the unlock position to the lock position.

Next, an embodiment according to the second invention shown in FIGS. 3 to 5 will be described. In this case, the inside handle 2 has three operation positions of a door open position, a door close / unlock position (neutral position) and a lock position, and one operation rod 12 as in the first invention. Connects the inside handle 2 and the handle lever 7 of the latch portion 6. Accordingly, the handle lever 7 to which one end of the operation rod 12 is connected rotates within an operation range corresponding to the three operation positions of the inside handle 2, and further interlocks with this operation to operate the handle via the connection rod 13. Lock lever 8 operatively connected to lever 7
Is rotated. By raising and lowering the lock operation portion 9 with which the convex portion 8a provided on the lock lever 8 is engaged, the lock mechanism of the latch portion 6 provided on the door 1 can be locked as in the first invention. , The switching operation of the lock position / unlock position is performed. The handle lever 7 described above is a member that operates a latch (not shown) by a switching operation between the door open position and the door closed position, as described in the first invention.

An upper end of the connecting rod 13 for connecting the handle lever 7 and the lock lever 8 described above is rotatably connected to the handle lever 7 and a lower end thereof is connected to the lock lever 8.
Are slidably coupled along an elongated hole 20 provided in the horn. The elongated hole 20 in this case is formed so that the lock lever 8 can rotate smoothly in conjunction with the handle lever 7, and has the same purpose as the elongated hole 14 forming the idle region of the first invention. Is different. With this connection structure, when the handle lever 7 is in the lock position, the lock lever 8 is also pushed down by the connection rod 13 to be in the lock position as shown by the solid line in FIG. When the lock operation section 9 is pulled down to the lock position, the latch section 6 of the door enters a locked state in which the lock mechanism functions.

Next, when the handle lever 7 rotates counterclockwise to switch from the lock position to the door closing / unlocking position, the interlocking lock lever 8 is also pulled up by the connecting rod 13 and counterclockwise. Rotate around. As a result, the lock operation section 9 with which the projection 8a engages is pushed up to the unlock position, so that the lock state of the lock mechanism is released. When the handle lever 7 rotates within the range of play between the locked position and the door closed / unlocked position, the latch engaged with the striker does not operate, and the door is kept closed. Dripping.

When the handle lever 7 is further rotated in the counterclockwise direction to switch from the door closed / unlocked position to the door open position, as shown by a broken line in FIG.
The lock lever 8 interlocked with the handle lever 7 is further pulled up by the connecting rod 13 and rotates in the same direction.
However, in such an operation region, since the engagement between the projection 8a and the lock operation section 9 is released, the projection 8a rotates while the lock operation section 9 remains at the unlock position. As a result, an idle area is formed in which the lock operation section 9 is not linked to the rotation of the lock lever 8, and in this area, the latch that engages with the striker is operated by the operation of the handle lever 7, but the door is operated. The lock lever 8 for switching the lock mechanism idles.

As shown in FIG. 3, the inside handle 2 for switching the handle lever 7 to three operating positions, ie, a lock position, a door closing / unlocking position, and a door opening position, is used. Axis 2 against
It is rotatably mounted with a as a fulcrum, and push-out operation and pull-out operation capable of selecting three operation positions corresponding to the respective operation positions of the handle lever 7 described above are possible. The inside handle 2 is normally closed at a position substantially on the same plane as the inside handle cover 26 provided on the side wall surface (for example, the trim 21) of the door 1, or the door close / unlock position. It stops at a position pushed out of the lock position to the outside of the vehicle compartment (indicated by a solid line in FIG. 3) and is held at one of the lock positions. As means for holding the inside handle 2 at the door closing / unlocking position, a spring (not shown) is generally employed. For example, when the inside handle 2 is pulled out from the door closed / unlock position toward the door open position located on the vehicle interior side from the door closed / unlock position, the spring is automatically moved to the neutral position by releasing the handle. Closed /
Functions as a return spring that returns to the unlock position.

On the other hand, as a means for holding the inside handle 2 at the locked position, which is another stop position, for example, a push latch 22 is preferable. The structure of the push latch 22 will be described below with reference to FIG. I do.
The push latch 22 is connected to the movable inside handle 2.
Latch 23 fixed to the base of
And a main body 24 fixed to the door 1 on the fixed side, and the main body 24 is provided with a floating latch 25.
The push latch 22 before locking the push latch striker 23 is in a state in which the floating latch 25 protrudes from the main body 24 (see FIG. 5A). 25 locks the push latch striker 23 in the main body 24 (see FIG. 5B), so that the inside handle 2 is held at the locked position by the action of the push latch 22. When the second pushing operation is performed from such a locked state, the lock of the push latch striker 23 by the floating latch 25 is released (see FIG. 5C), so that the inside handle 2 is closed / closed by the door. It automatically returns to the unlocked position and is held in the neutral state. At this time, the above-described unillustrated spring functions as a return spring that acts in a direction opposite to that when the inside handle 2 is operated in the door opening direction.

Hereinafter, the operation of the latch portion 6 according to the second invention will be described together with the operation of the inside handle 2 shown in FIG. When the door 1 is closed, the door latch and the striker engage to hold the door in a closed state. In this case, the inside handle 2, the handle lever 7, the lock lever 8, and the like are moved to the door closed / unlock position. And the lock operation unit 9 is in the unlock position where the lock mechanism is released. When the inside handle 2 stopped at the door closed / unlocked position is pushed toward the outside of the cabin, a switching operation to the locked position is performed, and the operation rod 12 is moved so as to be pushed out to the latch portion 6 side. Then, the handle lever 7 is rotated clockwise toward the lock position. Then, the lock lever 8 is interlocked with these operations via the connecting rod 13 and rotates in the same direction as the handle lever 7. As a result, the lock operating portion 9 engaged with the convex portion 8a integral with the lock lever 8 is pulled down from the unlocked position to the locked position, so that the lock mechanism is switched to the locked state, and the outside handle provided outside the vehicle compartment (shown in FIG. With the operation of (omitted), the door cannot be opened. Further, since the inside handle 2 is also held at the locked position in a stopped state, it can be easily confirmed that the lock mechanism is in the locked state only by looking at the pushed position of the handle 2.

To release such a locked state, the inside handle 2 held at the locked position by the action of the push latch 22 may be lightly pushed outward of the vehicle compartment.
By this operation, the push latch striker 23 provided on the inside handle 2 is released from the lock of the floating latch 25, and the inside handle 2 automatically returns to the door closed / unlocked position and stops. At the same time as this operation, the operation rod 12 is retracted toward the inside handle 2 (left side in the drawing), so that the handle lever 7 and the lock lever 8 also rotate counterclockwise toward the door closing / unlocking position, and 8a pulls up the lock operation section 9, and the locked state is released. Even if the handle lever 7 rotates between the lock position and the door closing / unlocking position, the latch does not operate, so that the latch engages with the striker to keep the door closed.

Next, when the door 1 is opened, the inside handle 2 stopped at one of the above-described door closed / unlocked position and the locked position is pulled out toward the passenger compartment from the door closed / unlocked position. The operation rod is moved to the door open position as described above.
Is further drawn into the inside handle 2 side from the door closing / unlocking position. As a result, the handle lever 7 and the lock lever 8 further rotate counterclockwise to the door open position, so that the handle lever 7 operates the latch to release the engagement with the striker. Therefore, although the opening operation of the door 1 becomes possible, the lock lever 8 is moved to the convex portion 8a.
Simply idles in an idle area where the lock operation unit 9 is not engaged. When the hand is released from the inside handle 2 after the door is opened, the handle 2 automatically returns to the neutral state of the door closing / unlocking position.

By the way, in the above-mentioned two embodiments, the interlocking of the inside handle 2 and the handle lever 7 and the lock lever 8 of the latch portion 6 according to the inside handle lock device of the automobile door has been mainly described. In the door latch portion 6, the handle lever 7 and the lock lever 8 are configured to be operated by other means such as a lock key (not shown) or an outside handle provided outside the door. However, in the description of the present invention, illustrations and detailed descriptions of configurations and operations of related known technologies, including door latches and door strikers, are omitted.

[0028]

According to the first and second aspects of the present invention, in any case, the operating range of the handle lever is expanded, and the inside handle is provided with a door lock function which has been provided with the conventional inside lock function. Therefore, only one operating rod is required to connect between the inside handle and the latch portion through the inside of the door, and the degree of freedom in designing the inside of the door is greatly improved in terms of securing space and the like. In addition, since rattle noise at the time of closing the door, which has been a problem when two operation rods are used, can be prevented, it is also effective in improving the commercial value.

Further, according to the configuration of the inside handle of the second invention, the operability when the door is opened is substantially the same as that of the override mechanism of the first invention.
Whether the lock mechanism is in the locked state or the unlocked state can be easily confirmed from the stop position of the inside handle.
