The handle unit portion 7 is formed by connecting an operation handle 1 as an operation member 2 and a lock knob 12 to a handle base 11 so as to be rotatable around a rotation center (C).

The operation handle 1 and the lock knob 12 are rotated between the initial rotation position shown in FIGS. , a torsion spring (not shown) applies a biasing force toward the initial rotation position.

As shown in FIGS. 5(a) and 5(b), the operating handle 1 and the lock knob 12 are each provided with a connecting recess 13 into which a connector 9 of a unit connecting body 10, which will be described later, can be fitted. The connecting concave portion 13 also rotates about the center of rotation (C) in accordance with the rotating operation to the 1st grade.

These connecting recesses 13 are open in the mounting direction of the unit connecting body 10 to the handle unit portion 7 when the operation member 2 is in the initial rotation position, and the cable (to be described later) is opened as the unit connecting body 10 is mounted. The connector 9 of the device 5 is locked, and the locking is released as the device is attached and detached.

As shown in FIG. 5(c), the lock knob 12 is formed by extending a cover portion 12c from the surface-side periphery of a hinge piece 12b in which a hinge hole 12a through which a rotating shaft (not shown) is inserted is formed. A connecting recess 13 is formed at one end of the hinge piece 12b. Further, in the vicinity of the connecting concave portion 13, a driving protrusion 12d is provided that protrudes in a direction parallel to the hinge hole 12a.

On the other hand, as shown in FIG. 4, the handle base 11 is provided with an opening 11a for fixing to the door panel 14 and a locking opening 11b for locking the first locking portion 15 of the unit connecting body 10, which will be described later.

On the other hand, as shown in FIG. 6, the unit connecting body 10 has a cable device 5 of a predetermined length in which the inner cable 4 is movably inserted into the outer cable 3, and a main body portion 8. A connector 9 is fixed to the tip of the cable 4 .

In this example, two pairs of cable devices 5 are arranged corresponding to the operation handle 1 and the lock knob 12 , and a spherical connector 9 is fixed to the tip of each inner cable 4 . As shown in FIG. 7, the connector 9 is formed in a barrel shape with a thick central portion and gradually reduced in diameter toward both ends.

Further, the body portion 8 is provided with first and second locking portions 15 and 16 that serve as connecting means to the handle unit portion 7 . The first engaging portion 15 extends rearward from the rear surface of the front edge of the main body portion 8 and then extends to the surface side, and is formed in a hook shape with its tip protruding rearward. The first engaging portion 15 is formed to be elastically deformable, and in this example, the elasticity is utilized by forming the main body portion 8 from a synthetic resin material.

On the other hand, the second locking portion 16 is formed so as to protrude from the rear edge portion of the main body portion 8 toward the surface side and protrude forward from the free end thereof. As will be described later, the second engaging portion 16 forms the center of rotation when connecting to the handle unit portion 7, and is formed to have an appropriate volume so as not to be easily elastically deformed or broken. be done.

Furthermore, as shown in FIG. 6, the main body portion 8 is provided with a cable holding portion 17 . The cable holding portion 17 has a pair of guide pieces 17a erected along the moving path of the connecting concave portion 13 when the operating handle 1 and the lock knob 12 of the handle unit portion 7 are operated while being connected to the handle unit portion 7. formed by Between the guide pieces 17a, a slightly larger gap is set than the interval between the end faces of the connector 9, and each guide piece 17a is provided with a guide hole 17b.

The guide hole 17b is formed in an arc shape that matches the locus of movement of the connecting recess 13 when the operating handle 1 and the lock knob 12 are operated with the body portion 8 connected to the handle unit portion 7 . The guide hole 7b is formed in a groove shape having a width dimension in which the guide projections 9a of the connector 9 can be movably fitted. is worn with

In order to introduce the guide protrusion 9a of the connector 9 into the guide hole 17b, the guide piece 17a is provided with an introduction opening 17c (see FIG. 6(a)).

As a result, when the connector 9 is attached to the cable holding portion 17, the connector 9 can move while being guided by the guide hole 17b, and both ends are in contact with the wall surface of the guide piece 17a. is restricted from being removed from the guide hole 17b.

The connection of the unit connecting body 10 to the handle unit portion 7 is first performed in a state where the door latch device 6 is connected to the other end of the cable device 5 prior to the connecting operation. By connecting the door latching device 6, the connector 9 moves to the rear end position of the guide hole 17a and corresponds to the position of the connecting recess 13 at the initial rotation position of the operating handle 1 and the lock knob 12. As shown in FIG.

As shown in FIG. 10, the connecting operation to the handle unit portion 7 is performed by engaging the second engaging portion 16 with the rear edge of the handle base 11 from the rear surface side, and then rotating counterclockwise in FIG. 10(a). , and the first engaging portion 15 is elastically engaged with the engaging opening 11b.

By rotating the unit connecting body 10, the connector 9 corresponding to the operating handle 1 is fitted into the connecting concave portion 13 of the operating handle 1 held in the initial rotation position by the torsion spring, and thereafter the operating handle 1 is operated. The force is passed through the inner cable 4 and operates the latch operating portion of the latch device to perform the latch release operation.

On the other hand, the body portion 8 is provided with a driving piece 8a in order to ensure the fitting of the corresponding connector 9 to the connecting concave portion 13 of the lock knob 12 whose rotational position is not determined when the handle unit portion 7 is alone. (See FIG. 6(a)).

The drive piece 8a is provided in a canopy shape so that the edge is positioned along the moving locus of the connecting body, and as shown in FIG. If not, the drive piece 8a abuts against the drive projection 12d of the lock knob 12 to move the lock knob 12 to the initial rotation position, after which the connector 9 is fitted into the connection recess 13 of the lock knob 12.

The unit connecting body 10 described above is manufactured by outsert-molding the main body portion 8 onto the outer cable 3 , and the outsert-molded main body portion 8 is integrated with the outer cable 3 inseparably.

In order to prevent deterioration of workability due to outsert molding to the outer cable 3 in a state in which the inner cable 4 is inserted, in this example, as shown in FIG. , the body portion 8 is outsert-molded to the outer cable 3.

After that, after the connector 9 is attached to the cable holding portion 17 of the main body portion 8 , the outer cable 3 is inserted from the opposite end of the inner cable 4 , that is, the end connected to the door latch device 6 . In order to facilitate the operation of inserting the inner cable 4 into the outer cable 3 , a taper 18 can be formed in the outer cable 3 and the connecting portion of the main body 8 to the outer cable 3 .

For mounting the above-described inside handle device to a vehicle, first, after fixing the handle unit portion 7 to the door panel 14, the unit connecting body 10 in which the other end of the cable device 5 is previously connected to the door latch device 6 is attached to the handle unit portion 7. It is done in conjunction.

As described above, since the connecting recess 13 of the operation member 2 in the handle unit 7 opens toward the movement path of the connector 9 during the connecting operation of the unit connecting body 10, it is possible to connect the unit connecting body 10. Accordingly, each connector 9 is locked to the corresponding operating member 2, and thereafter, remote control of the door latching device 6 becomes possible by operating the operating member 2. FIG.

Therefore, in this example, even when an impact force such as a side collision of the vehicle is applied, the outer cable 3 does not separate from the handle device, so that the operation force is not applied only to the inner cable 4. , careless release of the door latch device 6 is prevented.

Further, when the unit link 10 is separated from the handle unit portion 7 due to the impact force, the connection between the connector 9 and the operating member 2 is released. Since the relative position of the connector 9, ie, the inner cable 4, relative to the outer cable 3 does not change, the door latch device 6 is prevented from being released carelessly.

Furthermore, since the connector 9 is held by the cable holding portion 17 so as not to be detachable in the unit connecting body 10 after the separation, the connector 9 may be detached from the main body portion 8 and, for example, may be caught by another member, causing an inner Inadvertent release of the door latch device 6 is prevented because force is not applied only to the cable 4.例文帳に追加
