Description

  The present invention relates to a vehicle door handle device.

  As a known door handle device, there is one described in Patent Document 1 described later. The door handle will be described with reference to FIG.

  The door handle device includes a frame 2 fixed to the back side 1b of the door panel 1 of the vehicle, a grip 3 disposed on the frame 2 from the front side 1a of the door panel 1, and a lever 4 rotatably supported by the frame 2. And. On one end side (left side in FIG. 7) of the grip 3 in the longitudinal direction (left and right direction in FIG. 7), an engagement leg portion 3a that engages with the support portion 2a provided on the frame 2 is formed. The grip 3 is supported by the frame 2 so as to be tiltable at the engaging leg 3a. On the other end side in the longitudinal direction of the grip 3 (the right side in FIG. 7), an engaging arm portion 3b that engages with the lever 4 is formed. The lever 4 is connected to a rod (not shown) for operating a door lock device (not shown).

In the state shown in FIG. 7, when the grip 3 is pulled toward the door panel 1 in the vehicle exterior direction (upward in FIG. 7) (opening operation), the grip 3 engages with the support portion 2 a of the frame 2. It tilts toward the outside of the vehicle compartment with respect to the frame 2 around the leg 3a. Along with this, the lever 4 engaged with the engaging arm portion 3b of the grip 3 rotates, and the door lock device connected to the lever 4 opens. Thereby, the door (not shown) can be opened.
JP 2002-4649 A (refer to page 2-4, FIG. 2)

  By the way, in the door handle device described above, the grip 3 that is opened is tilted toward the outside of the vehicle room with respect to the frame 2 around its own engaging leg 3a that engages with the support 2a of the frame 2. In this case, the position of the engagement leg 3a of the grip 3 is not restricted with respect to the position of the support 2a of the frame 2 that supports the engagement leg 3a in the longitudinal direction, and the tilt of the grip 3 with respect to the frame 2 is not restricted. The center position is not held in the longitudinal direction of the grip 3. That is, the engagement leg 3a of the grip 3 may move relative to the support 2a of the frame 2 in the longitudinal direction. For this reason, when the grip 3 is opened, the grip 3 (grip member) may rattle with respect to the frame 2 (base member) in the longitudinal direction.

  Therefore, the present invention has been made in view of the above-described problems, and an object thereof is to more reliably prevent rattling in the longitudinal direction of the grip member with respect to the base member.

  In order to solve the above problems, the technical means taken in the present invention is, as claimed in claim 1, a base member fixed to the back surface of a door panel of a vehicle, and a tiltable support supported by the base member. In the vehicle door handle device having a grip member disposed on the base member from the surface of the door panel, a tilting shaft rotatably supported by the base member and having a flat surface on the outer peripheral surface thereof. A bearing hole provided in the grip member and having an inner peripheral surface that is in sliding contact with the outer peripheral surface of the tilting shaft when the grip member is tilted with respect to the base member; and the grip member is provided continuously with the bearing hole. And having a guide groove that matches the flat surface of the tilt shaft.

  Preferably, as described in claim 2, the tilting of the grip member with respect to the base member may be performed in a range in which the flat surface of the tilting shaft does not coincide with the guide groove.

  According to the present invention, the outer peripheral surface of the tilting shaft that is rotatably supported by the base member is in sliding contact with the inner peripheral surface of the bearing hole of the grip member. Thereby, the position of the bearing hole of the grip member with respect to the base member is restricted with respect to the longitudinal direction. That is, the position of the tilt center when the grip member is tilted with respect to the base member is maintained with respect to the longitudinal direction of the grip member. Therefore, rattling in the longitudinal direction of the grip member with respect to the base member can be prevented.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  FIG. 1 is a perspective view of a door 8 of a vehicle. In the present embodiment, the door 8 will be described as a side door of the vehicle. However, the present invention is not limited to this and may be a back door of the vehicle. An outer handle 10 (vehicle door handle device) is disposed on the outer panel 9 (door panel) forming the door 8. The outside handle 10 is operated to open (close) the door 8 relative to the body (not shown).

  FIG. 2 is a cross-sectional view taken along line AA in FIG. 1 and shows a state in which the outside handle 10 is disposed on the outer panel 9 of the door 8.

  The outside handle 10 includes a handle grip 11 (grip member) and a handle frame 12 (base member).

  The handle frame 12 includes a curved portion 12a that aligns with the concave portion 9a of the outer panel 9 in the vicinity of the center in the longitudinal direction (L direction in FIGS. 2 and 4). In the handle frame 12, two frame openings 12d and 12e are formed on both sides in the longitudinal direction with the curved portion 12a interposed therebetween. On the other hand, panel openings 9d and 9e are also formed in the outer panel 9. In a state where the handle frame 12 is fixed to the outer panel 9, the frame openings 12d and 12e are in a positional relationship corresponding to the panel openings 9d and 2e, respectively.

  The handle frame 12 is fixed to the door inner side surface 9b (back surface) of the outer panel 9 on both sides in the longitudinal direction across the curved portion 12a. On one end side (the right side in FIG. 2) of the handle frame 12, a key cylinder 23 and a cap 24 covering the key cylinder 23 are disposed in the frame opening 12e. Further, a screw 25 is disposed on one end side of the handle frame 12. The screw 25 connects the handle frame 12 and the key cylinder 23. When the screw 25 is screwed, the handle frame 12 and the key cylinder 23 are configured to sandwich the outer panel 9, and one end side of the handle frame 12 is fixed to the outer panel 9 by this clamping force.

  The other end side (the left side in FIG. 2) of the handle frame 12 is fixed to the outer panel 9 via a nut 21 and a screw 22. The nut 21 is configured such that the outer panel 9 can be sandwiched between the nut 21 and the handle frame 12. Then, when the screw 22 is screwed into the nut 21, the nut 21 and the handle frame 12 sandwich the outer panel 9, and the handle frame 12 is fixed to the outer panel 9.

  The handle grip 11 has a long shape and includes a support arm 31 and an operation arm 32.

  The operating arm 32 is formed on one end side (right side in FIG. 2) of the handle grip 11 in the longitudinal direction (L direction in FIGS. 2 and 3), and extends to the door 8 side (lower side in FIG. 2). ing. The operating arm 32 extends into the door 8 through the panel opening 9 e of the outer panel 9 and is supported in the frame opening 12 e of the handle frame 12. With this support, the operating arm 32 of the handle grip 11 is connected to the door 8. Further, the operating arm 32 is engaged with the bell crank arm 33 at the tip thereof. The bell crank arm 33 is connected to a door lock device (not shown) disposed in the door 8 via a rod or the like (not shown).

  The support arm 31 is formed on the other end side in the longitudinal direction of the handle grip 11 (left side in FIG. 2). The support arm 31 extends into the door 8 through the panel opening 9d of the outer panel 9, and is inserted into the arm accommodating portion 20 of the handle frame 12 through the frame opening 12d. That is, the handle grip 11 is disposed on the handle frame 12 from the door outer surface 9 c (front surface) of the outer panel 9. The support arm 31 is tiltably supported by the arm accommodating portion 20 of the handle frame 12 via the shaft member 40 at a fitting portion 31a provided at the tip thereof. With this support, the support arm 31 of the handle grip 11 is connected to the door 8. Hereinafter, the structure of the fitting part 31a of the support arm 31, the arm accommodating part 20 of the handle frame 12, and the shaft member 40 will be described with reference to FIGS.

  FIG. 3 is a perspective view showing the support arm 31 of the handle grip 11. A fitting portion 31 a is provided at the tip of the support arm 31. The fitting portion 31a is roughly concave in the longitudinal direction of the handle grip 11 (L direction in FIG. 3). The fitting part 31a includes a holding part 31b (bearing hole) and an insertion part 31d (guide groove).

  The holding portion 31b extends in the vertical direction (U direction in FIG. 3) of the handle grip 11 at the tip of the support arm 31. The holding part 31b is a through hole having an arcuate inner peripheral surface 31c. The insertion part 31d is provided so as to be continuous with the holding part 31b. The insertion portion 31d is formed by a pair of tip surfaces 31e that are continuous with the inner peripheral surface 31c of the holding portion 31b and face each other with a predetermined gap. The size of the gap of the insertion portion 31d is set smaller than the diameter of the inner peripheral surface 31c of the holding portion 31b.

  FIG. 4 is a perspective view showing the shaft member 40 and the arm housing portion 20 that supports the support arm 31 via the shaft member 40.

  The shaft member 40 includes a base portion 40a having a plate shape and a columnar holding shaft portion 40b (tilting shaft) extending from the base portion 40a. The shape of the cross section of the holding shaft portion 40b is oval (oval). The outer peripheral surface 40d of the holding shaft portion 40b has a pair of arcuate surfaces 40c having a long diameter and a pair of flat surfaces 40e continuous to the arcuate surface 40c. The outer peripheral surface 40d of the holding shaft portion 40b is in sliding contact with the inner peripheral surface 31c (see FIG. 3) of the holding portion 31b of the support arm 31 described above on the arc surface 40c. The flat surface 40e is formed to match the insertion portion 31d of the support arm 31. The shaft member 40 is inserted into the arm accommodating portion 20 of the handle frame 12 at the holding shaft portion 40b.

  As shown in FIG. 4, in the arm accommodating part 20, the opposing surface 20a is provided in each side of the up-down direction (U direction shown in FIG. 4) of the handle frame 12. As shown in FIG. An insertion hole 20b is provided in the facing surface 20a. The insertion hole 20b penetrates the opposing surface 20a in the vertical direction of the handle frame 12, and has a round hole shape. The holding shaft portion 40b of the shaft member 40 described above is inserted into the insertion hole 20b as indicated by a two-dot chain line in the drawing. The holding shaft portion 40b is rotatable with respect to the insertion hole 20b (opposing surface 20a). That is, the holding shaft portion 40b is structured to be rotatably supported on the facing surface 20a of the handle frame 12. The inner diameter of the insertion hole 20 b is formed so as to correspond to the major diameter of the holding shaft portion 40 b of the shaft member 40. Therefore, when the holding shaft portion 40b is inserted into the insertion hole 20b, the movement of the holding shaft portion 40b with respect to the insertion hole 20b is restricted in the longitudinal direction of the handle frame 12. That is, the shaft member 40 is held by the handle frame 12 in the longitudinal direction of the handle grip 11 in a state where the holding shaft portion 40b of the shaft member 40 is inserted into the insertion hole 20b of the arm housing portion 20. It has become.

  Next, a mode in which the support arm 31 of the handle grip 11 is assembled to the arm accommodating portion 20 of the handle frame 12 will be described with reference to FIGS. 5 and 6. 5 and 6 are diagrams schematically showing a mode in which the support arm 31 is assembled to the arm accommodating portion 20.

  When the support arm 31 is assembled to the arm housing portion 20, first, as shown in FIG. 5, the state in which the long diameter of the holding shaft portion 40b of the shaft member 40 is along the longitudinal direction of the handle frame 12 (the left-right direction in FIG. 5) Thus, the holding shaft portion 40b is rotated with respect to the arm housing portion 20. In this state, the support arm 31 is inserted into the arm accommodating portion 20 through the frame opening 12d (see FIG. 2), and the fitting portion 31a of the support arm 31 is directed toward the holding shaft portion 40b of the shaft member 40. , Move in the direction of the arrow in the figure. And as shown with the dashed-two dotted line in FIG. 5, the state which the holding shaft part 40b of the shaft member 40 was inserted in the holding part 31b following this insertion part 31d via the insertion part 31d of the fitting part 31a (Shown in FIG. 6).

  Subsequently, in the state shown in FIG. 6, the holding shaft portion 40 b is moved to two points in FIG. 6 so that the long diameter of the holding shaft portion 40 b of the shaft member 40 is along the vertical direction of the handle frame 12 (vertical direction shown in FIG. As indicated by the chain line, the arm accommodating portion 20 is rotated. By this rotation of the holding shaft portion 40b, the arcuate surface 40c of the holding shaft portion 40b comes into sliding contact with the inner peripheral surface 31c of the holding portion 31b (see FIGS. 3 and 4). Note that the size of the gap between the insertion portion 31d continuous with the holding portion 31b is set to be smaller than the diameter of the inner peripheral surface 31c of the holding portion 31b, so that the holding shaft portion 40b of the shaft member 40 is separated from the holding portion 31b. Never leave. Accordingly, the fitting portion 31 a of the support arm 31 is held with respect to the holding shaft portion 40 b of the shaft member 40 in the longitudinal direction of the handle grip 11 (the left-right direction in FIG. 6). That is, with respect to the longitudinal direction of the handlebar grip 11, the position of the holding portion 31b of the support arm 31 is restricted with respect to the arm housing portion 20 of the handle frame 12 via the shaft member 40 (holding shaft portion 40b).

  In this case, the handle grip 11 (see FIG. 2) is tilted in the vehicle exterior direction (upward in FIG. 6) with respect to the handle frame 12 around the holding portion 31b of the fitting portion 31a of the support arm 31. That is, the holding portion 31 b and the holding shaft portion 40 b of the shaft member 40 fitted to the holding portion 31 b form a tilt center when the handle grip 11 tilts with respect to the handle frame 12.

  Hereinafter, the operation of the outside handle 10 will be briefly described with reference to FIG.

  When the door 8 is opened, a hand is put in the space between the handle grip 11 and the outer panel 9, and the handle grip 11 is pulled outward (upward in FIG. 2). As a result, the handle grip 11 tilts in the vehicle exterior direction with respect to the handle frame 12 around the holding portion 31b (see FIG. 3) of the fitting portion 31a of the support arm 31. At this time, the operating arm 32 of the support arm 31 is moved outward of the vehicle compartment, and the bell crank arm 33 engaged with the operating arm 32 is operated. As a result, the latch mechanism (not shown) of the door lock device is activated, and the door 8 is opened relative to the body. The tilt of the handle grip 11 with respect to the handle frame 12 is such that the flat surface 40e (see FIG. 4) of the holding shaft portion 40b of the shaft member 40 is different from the insertion portion 31d (see FIG. 3) of the fitting portion 31a of the support arm 31. It has a structure that does not match.

  As described above, according to the outside handle 10 of the present invention, the arcuate surface 40c of the holding shaft portion 40b of the shaft member 40 is in sliding contact with the inner peripheral surface 31c of the holding portion 31b of the support arm 31, so that the handle grip 11, the holding portion 31b is held with respect to the holding shaft portion 40b. Thereby, the position of the holding portion 31b of the handle grip 11 (support arm 31) with respect to the handle frame 12 is restricted with respect to the longitudinal direction thereof. In other words, the position of the tilt center when the handle grip 11 tilts with respect to the handle frame 12 is maintained with respect to the longitudinal direction of the handle grip 11. Therefore, rattling in the longitudinal direction of the handle grip 11 with respect to the handle frame 12 can be prevented. As a result, the operation feeling of the handle grip 11 related to the operation of the door 8 is improved, and the merchantability of the outside handle 10 can be enhanced.
