Description

  The present invention relates to a vehicle door inside handle device.

  As an inside handle device that transmits operating force to a door lock device using a cable device, a device described in Patent Document 1 is known. In this conventional example, the inside handle (operating member) connected to the handle base is formed with a slit-like opening and a perfect circular opening, and the cable device is connected to a cylindrical cable fixed to the tip of the inner cable. The end is inserted into the perfect circular opening and the base end of the cable end is inserted into the slit opening.

  However, in the above-described conventional example, the slit-like opening that sandwiches the inner cable is effective for guiding the moving direction of the inner cable to prevent the cable end from being detached from the perfect circular opening. In order to prevent scratching noise caused by sliding, uniform grease application over the entire length of the path is required, and there is a problem that assembly workability is poor.

  In particular, as will be described later, in order to prevent deformation such as buckling, it is necessary to make the guide path length by the slit-shaped opening long, so that uniform application of grease becomes more difficult.

  The problem is that the slit opening is widened to the extent that sliding contact with the inner cable does not occur, or the path length of the slit opening is shortened as much as possible within a range that can prevent the cable end from being detached. However, in this case, the following problem occurs. That is, for example, when the operation of the inner cable is pulled out and the operation member is operated in the inner cable immersion state, if a failure occurs in the following operation of the inner cable, the inner cable buckles and is detached from the cable end. Directional force is applied, and the inner cable may fall off the operating member.

  The present invention has been made to eliminate the above-mentioned drawbacks, and provides a vehicle door inside handle device that is excellent in assembling workability and can surely prevent inadvertent dropping of the inner cable. With the goal.

  The inside handle device has an operation member 5 that is rotatably supported on the handle base 1. The operation member 5 has a wire fitting hole 7 and a cable pressing portion 8, and the handle base 1 has a guide portion 9. Is provided.

A connecting projection 6 formed on the inner cable 4 of the cable device 3 is fitted into the wire fitting hole 7 of the operation member 5, and the cable pressing portion 8 presses the wire portion of the inner cable 4 to form the connection protruding portion 6. Dropping from the wire fitting hole 7 is prevented.

  The guide portion 9 cooperates with the cable pressing portion 8 to support the inner cable 4 at two points in the separated position. For example, when the drawn-out inner cable 4 is prevented from being inserted into the outer case 10 due to catching or the like. Even so, the moving direction of the inner cable 4 is guided to regulate abnormal deformation such as buckling.

  Therefore, according to the present invention, since it is not necessary to lengthen the guide path length by the cable pressing portion 8, there is no need for the troublesome work of uniformly applying the grease over the entire length of the relatively long path length. Will improve.

  Further, since abnormal deformation due to buckling or the like of the inner cable 4 can be surely prevented, the inner cable 4 does not fall off from the operation member 5.

Further, when the cable holding portion 8 is formed adjacent to the wire fitting hole 7, the grease supplied to the wire fitting hole 7 wraps around the cable holding portion 8 together with the operation of the inner cable 4. Only the application of grease is sufficient, and workability is further improved.
According to the present invention,
An operation member 5 is connected to the other end of the inner cable 4 in the cable device 3 that is pivotally supported by the handle base 1 so as to be rotatable and one end is connected to the door lock device 2 in the door body,
The connection between the inner cable 4 and the operation member 5 is performed by fitting a connection protrusion 6 formed at the tip of the inner cable 4 into a wire fitting hole 7 formed in the operation member 5, and the operation member. 5 is provided with a cable pressing portion 8 for restricting the movement of the connecting projection 6 in the direction of dropping from the wire fitting hole 7.
In addition, the handle base 1 cooperates with the cable pressing portion 8 to support the inner cable 4 at two points in the separated position to restrict abnormal deformation of the inner cable 4 and to connect the wire fitting hole 7 of the connecting projection 6. It is also possible to provide a vehicle door inside handle device that is provided with a guide portion 9 that prevents detachment from the vehicle.

  According to the present invention, the assembly workability can be improved, and the inadvertent dropping of the inner cable can be reliably prevented.

It is a front view which shows an inside handle apparatus. 2A is a cross-sectional view taken along line 2A-2A, and FIG. 2B is a cross-sectional view taken along line 2B-2B. 3A is a cross-sectional view taken along line 3A-3A, and FIG. 3B is a cross-sectional view taken along the direction 3B in FIG. It is a figure which shows an operation handle, (a) is a front view, (b) is a 4B direction arrow view of (a), (c) is a 4C direction arrow view of (b), (d) is a view of (b). It is a 4D-4D line sectional view.

  As shown in FIG. 1 and subsequent figures, the inside handle device is configured such that an operating handle (operating member 5) and a lock lever 11 are pivotally operated using a pivot 12 on a handle base 1 fixed to a door panel (not shown). It is formed to support.

  A cable device 3 in which the inner cable 4 is slidably inserted into the outer case 10 is connected to the operation handle 5 and the lock lever 11, and as will be described later, the operation handle 5 is rotated from the initial position to the operation position. When operated, the door lock device 2 is unlocked and the door body can be opened. When the lock lever 11 is rotated from the unlock position to the lock position, the cancel portion 2a of the door lock device 2 is activated, The operation from the operation handle 5 is canceled, and the door body cannot be opened by the operation handle 5.

  As shown in FIG. 2 (b), the lock lever 11 is formed by injection molding a synthetic resin material, and an operation bulge portion 11 a sandwiches the pivot 12 on the externally exposed surface when mounted on the handle base 1. A cable mounting hole 11b is provided at the opposite end.

  As shown in FIG. 1, a cable end 4a whose tip is bent in an L-shape is fixed to the inner cable 4 of the cable device 3 corresponding to the lock lever 11, and the cable end 4a is attached to the cable mounting. It is inserted into the hole 11 b and connected to the lock lever 11.

  On the other hand, as shown in FIGS. 2 and 4, the operation handle 5 is provided with a handle 5 a at one end and a wire fitting hole 7 at the opposite end across the rotation center, and around the pivot 12 in FIG. A rotation operation is performed between an initial position indicated by a solid line and an operation position indicated by a chain line. As shown in FIG. 3, the operation handle 5 is given a biasing force toward the initial position by the torsion spring 13.

  As shown in FIG. 3 (b), the cable device 3 corresponding to the operation handle 5 is attached to the end portion of the outer case 10 locked to the cable locking portion 1a formed on the handle base 1, and the inner cable. A spherical connecting projection 6 fixed to the tip of 4 is fitted into the wire fitting hole 7 of the operation handle 5. In order to guide the inner cable 4 drawn from the outer case 10 to the wire fitting hole 7, the handle base 1 is provided with a guide portion 9 so as to sandwich the inner cable 4.

  As shown in FIG. 4, the wire fitting hole 7 is formed as a bottomed hole having a cross-sectional area into which the connecting projection 6 of the inner cable 4 established on the side wall surface of the operation handle 5 can be fitted. It is opened to the outside of the operation handle 5 through the wire insertion slit 14.

  The wire insertion slit 14 is bent in the circumferential direction from the introduction portion 14a cut out along the depth direction of the wire fitting hole 7 with the wall surface where the wire fitting hole 7 is opened as a base end. It has an open portion 14b and is formed in a crank shape. The open portion 14b is formed with a relatively wide path width in order to prevent unnecessary sliding contact with the operating inner cable 4, and only the boundary portion with the introduction portion 14a protrudes from the boundary portion. The width is narrowed by the pressing portion 8.

  In FIG. 4 (d), the narrow portion formed by the introduction portion 14 a is shown to be formed slightly wider than the diameter of the inner cable 4, but the cable pressing portion 8 is connected to the wire fitting hole 7. The width of the narrowed portion may be formed larger than that shown in the drawing in order to suppress the dropping of the portion 6.

  FIG. 4D shows a case where the surface opposite to the surface on which the cable pressing portion 8 is formed is formed by a flat surface. However, in order to reduce the contact area with the inner wire, the cable pressing portion 8 is used. It can also be recessed except for the part which opposes.

  With the above configuration, the cable device 3 is mounted by first fitting the connecting protrusion 6 of the inner cable 4 into the wire fitting hole 7 and inserting the inner wire into the introduction portion 14a of the wire holding slit 14. Thereafter, the entire cable device 3 is rotated to move the inner cable 4 to the opening portion 14b, and after passing the guide portion 9 of the handle base 1, the case end of the outer case 10 is locked to the handle base 1. Done.

  When the cable device 3 is mounted, grease is supplied to the wire fitting hole 7, and the grease wraps around the narrow portion by the cable pressing portion 8 in connection with the connection work, thereby preventing the generation of sliding noise during operation.

  Therefore, in this embodiment, as shown in FIG. 4 (d), the inner cable 4 is in a two-point support state by the narrow portion by the cable pressing portion 8 and the guide portion 9 of the handle base 1. The narrow portion and the guide portion 9 can prevent harmful deformation such as buckling of the inner cable 4 that causes the connection protrusion 6 to fall out of the wire fitting hole 7, and the inner cable 4 The position and dimension at which the sliding contact during operation is reduced as much as possible are obtained, for example, experimentally. As a result, the management of grease application due to the increase in the guide path length of the inner cable 4 becomes unnecessary. Also, the inner cable 4 does not fall off from the operation handle 5.

  In the above description, only the operation handle 5 is targeted as the operation member 5, but a similar structure can be employed on the lock lever 11 side.
