Description

  The present invention relates to a vehicle door handle device.

  As a door handle device using a cable device in which an inner cable is inserted into an outer cable as an operating force transmission means, the one described in Patent Document 1 is known. In the prior art, the door handle device is formed by rotatably connecting a door handle to a handle base. The door handle is formed with a circular hole-shaped locking portion and a notch that is open to the side wall of the door handle and communicates with the locking portion. The cable device is first attached to a circle formed at the cable end of the inner cable. After fitting the columnar cable end to the locking part, rotate the cable device around the fitting part with the locking part to insert the inner cable near the cable end through the notch, and then connect the outer cable to the handle base It is carried out by locking.

  However, in the above-described conventional example, on the assumption that only the tension is applied to the inner cable, the cable end is prevented from dropping due to the load in the tension direction. If an unexpected load such as a load in the direction is applied, the possibility that the cable end may fall off from the locking part cannot be denied. When the connection with the cable is released, there is a problem that the operation with the handle becomes impossible thereafter.

  The present invention has been made to solve the above-described drawbacks, and an object of the present invention is to provide a vehicle steering device with high operational reliability.

  The handle device has an operation handle 1 that is rotatably attached to a door of a vehicle, and the displacement of the output unit 2 caused by the operation of the operation handle 1 is connected via a cable device 3 connected to the output unit 2. It is configured to transmit to the door lock device 4 and drive the door lock device 4. When the operation handle 1 and the door lock device 4 are directly connected via the cable device 3, the output unit 2 is formed on the operation handle 1 itself, for example, the arm portion of the operation handle 1, and rotates to the operation handle 1. When the operating force is transmitted to the door lock device 4 via the lever 12 connected to the handle base 11 that supports the operating handle 1, the operating force can be formed on the lever 12.

  The cable device 3 is formed by inserting the inner cable 14 into the outer cable 13. The cable device 3 is attached to the output unit 2 by locking the cable end 5 of the inner cable 14 in the locking groove 6 formed in the output unit 2. Done. The operation force transmission using the cable device 3 is based on a pull operation with a pulling force applied to the inner cable 14 as a driving direction or a push operation using a compressive force applied to the inner cable 14 as a driving force. There may be.

The lock member 7 attached to the output unit 2 can be moved between the end attachment position and the lock position. When the lock member 7 is in the end attachment position, the attachment path to the locking groove 6 of the cable end 5 is opened. Then, the mounting path to the locking groove 6 is closed by holding the locking portion 8 in the locked position.

Therefore, in the present invention, when the cable end 5 is mounted with the lock member 7 in the end mounting position, and then the lock member 7 is moved to the lock position and held in the lock position by the locking portion 8 , the cable end 5 Since the mounting path is physically blocked, the inner cable 14 is completely prevented from being detached from the output section 2 regardless of what force is applied to the cable device 3. For this reason, the reliability of the operation is remarkably improved, and it is not necessary to set the mounting direction of the cable end 5 in a direction not to be detached when the inner cable 14 is operated. Work becomes easy.

  In addition, since the lock member 7 is mounted on the output unit 2 in advance and supplied to the cable mounting process, it is possible to prevent the number of mounting steps of the lock member 7 in the cable mounting process or the dissipation of the lock member 7.

  When pulling the cable device 3, the wall surface on which the locking groove 6 is formed functions as an end abutment wall 10 as an operating force transmission unit to the cable end 5, so that a direction in which compression force is generally applied to the cable end 5 Is formed in an open state. As described above, forming the end abutting wall 10 only in the pull direction with respect to the cable end 5 and opening it without forming the operation wall surface in the push direction which is not normally used is to make the output unit 2 by sheet metal or the like. It can be expected to reduce the manufacturing man-hours (bending man-hours) when forming, and it can also be expected to improve the mounting workability by increasing the route space when mounting the cable. In some cases, the following problems may occur.

  That is, after operating the operating handle 1 in the handle device and pulling the cable device 3 to operate the door lock device 4 and then releasing the operating force, the operating handle 1 is initialized by a return spring incorporated in the handle device. At the same time, the door lock device 4 is also returned to the initial state by the return spring incorporated in the door lock device 4. At this time, if the return of the door lock device 4 to the initial state is hindered for some reason, only the operation handle 1 returns to the initial position. As described above in this state, if the operation handle 1 does not have an operation force transmission wall in the push direction, the output unit 2 is in an idle state with respect to the cable end 5 even if a rotation operation is given to the operation handle 1. Thereafter, operation force transmission to the inner cable 14 by the operation handle 1, that is, operation to the door lock device 4 becomes impossible.

On the other hand, when the lock member 7 is formed to interfere with the cable end 5 at the locked position so as to be able to be pushed to the cable end 5, a stick phenomenon or the like of the door lock device 4 or the inner cable 14 with respect to the outer cable 13 occurs. Even if it occurs, an operating force is applied to the cable device 3 with the return of the operation handle 1, and it is possible to reliably return to the initial state.
According to the present invention,
A vehicle door handle device that transmits a displacement of the output unit 2 due to a rotation operation to the operation handle 1 attached to the vehicle door to a door lock device 4 in the door via a cable device 3 connected to the output unit 2. Because
The output unit 2 includes a lock position that closes the release path of the cable end 5 from the locking groove 6 that locks and holds the cable end 5 of the cable device 3 and an end mounting position that opens the release path. It is also possible to provide a vehicle door handle device to which a lock member 7 that is movable and can be held in a lock position is mounted.

  According to the present invention, since the cable device does not detach from the output unit during operation, the operation reliability can be improved.

As shown in FIG. 4, an arm locking portion 12 b having a U-shaped cross section is formed at one end portion of the lever 12 by bending the opposite side to the surface side. In this specification, the “front and back” direction is based on the mounting posture to the vehicle. The arm portion 1b of the operation handle 1 is locked to the arm locking portion 12b. When the operation handle 1 is rotated from the initial rotation position, the lever 12 rotates clockwise in FIG. (See FIG. 3). A biasing force toward the initial position is applied to the lever 12 by the torsion spring 15, and the operation handle 1 is also biased toward the initial rotation position by this biasing force.

  Further, a cable connecting portion as the output portion 2 is formed at the opposite end of the lever 12 to the arm locking portion 12b, and the inner cable 14 of the cable device 3 is connected to the cable connecting portion 2. As shown in FIG. 4, the cable connecting portion 2 includes a bent piece 2a toward the front surface, an end contact wall 10 formed by bending one end of the bent piece 2a into an L shape, and a bent tip piece. 2b and has a U-shape when viewed from the back. The bent tip piece 2b and the end contact wall 10 are formed with slit-like locking grooves 6 that are opened to the edge of the bent tip piece 2b.
