DETAILED DESCRIPTION OF THE INVENTION
As shown in FIGS. 1 to 3, the door outside handle 2 attached to the outer panel 1 of the vehicle door is supported on the outer panel 1 from the inside of the vehicle door, and is rotatably supported by the frame 21. A lever 23, a grip-type handle body 24 supported by the frame 21 so as to be tiltable from the outside of the outer panel 1, and a coil spring 25 that urges the lever 23 to rotate.
[0011]
The frame 21 has a long shape extending in the front-rear direction of the vehicle (the left-right direction in FIG. 1), and a pair of insertion ports 21a and 21b are formed on the front end side and the rear end side thereof. The frame 21 is integrally formed with a support portion 3 for supporting the handle body 24 in the vicinity of the insertion port 21a and a support portion 4 for supporting the lever 23 in the vicinity of the insertion port 21b. ing.
[0012]
As shown in FIGS. 4 to 6, the support portion 4 is composed of a pair of vertical walls 41, 42 arranged to face each other with a predetermined interval in the front-rear direction of the vehicle. It arrange | positions so that the vertical wall 42 may be located in between. Support holes 41a and 42a are formed on the inner surfaces of the vertical walls 41 and 42 facing each other. As shown in FIGS. 7 to 9, the lever 23 has a substantially L-shaped bell crank shape in which an input portion 23a and an output portion 23b are formed. A pair of support shafts 5 and 6 are formed in the bent portion between the input portion 23a and the output portion 23b of the lever 23 so as to protrude in directions away from each other and to be inserted into the support holes 41a and 42a of the vertical walls 41 and 42. The tip portions 51 and 61 of the support shafts 5 and 6 have a two-sided width shape in which a pair of flat surfaces are formed on a part of the outer circumferential surface thereof. The longitudinal walls 41 and 42 are formed with guide grooves 41b and 42b that follow the support holes 41a and 42a in the longitudinal direction. The guide grooves 41 b and 42 b have a two-sided width shape in which a pair of flat surfaces are formed on a part of the inner circumferential surface so as to match the two-sided width shape of the tip portions 51 and 61 of the support shafts 5 and 6. Presents. Therefore, the support shafts 5 and 6 are at the tip end portions of the support shafts 5 and 6 at a desired rotation position of the lever 23 with respect to the frame 21 (a position outside a predetermined stroke range from an initial position of the lever 23 described later to a maximum stroke position). When 51 and 61 and the guide grooves 41b and 42b of the vertical walls 41 and 42 match, they are inserted into the support holes 41a and 42a. The lever 23 is rotatably supported by the frame 21 by inserting the support shafts 5 and 6 into the support holes 41a and 42a.
[0013]
The root portion 52 of the one support shaft 5 has a cylindrical shape with a diameter larger than the diameter of the support hole 41 a and the width of the guide groove 41 b, and its end surface comes into contact with the inner surface of the wall portion 41. ing. As shown in FIG. 10, the distance A between the end surface of the root portion 52 of the support shaft 5 and the side surface of the lever 23 on the support shaft 6 side is smaller than the distance B between the inner surfaces of the vertical walls 41 and 42. The lever 23 is movable in the axial direction (front-rear direction of the vehicle) with respect to the frame 21 by the difference between the distance A and the distance B.
[0014]
One vertical wall 41 is formed with a fitting hole 41c following the support hole 41a in the thickness direction. The fitting hole 41 c has a two-sided width shape in which a pair of flat surfaces are formed on a part of the inner circumferential surface so as to match the shape of the tip portion 51 of the support shaft 5. Therefore, when the distal end portion 51 and the fitting hole 41c match at a predetermined stroke position of the lever 23 with respect to the frame 21, the lever 23 moves in the axial direction from the position of the solid line in FIG. 10 to the position of the dashed line in FIG. The tip portion 51 is fitted into the fitting hole 41c by moving in the direction opposite to the direction in which the 24 is assembled to the frame 1 in the direction C in FIG. 1 and FIG. When the front end portion 51 and the fitting hole 41c are fitted, the rotation of the lever 23 is restricted on the respective flat surfaces, whereby the lever 23 is held at a predetermined stroke position. Further, as shown in FIG. 10, a locking projection 41d is formed on the inner surface of the fitting hole 41c, and a locking groove 51a for locking the locking projection 41d is formed on the outer surface of the tip portion 51. Yes. When the distal end portion 51 of the support shaft 5 is fitted into the fitting hole 41c, the locking projection 41d is locked in the locking groove 51a, whereby the distal end portion 51 is inadvertently released from the fitting hole 41c. Thus, the movement of the lever 23 in the axial direction (the direction D in FIG. 1 and FIG. 10 in the direction in which the handle main body 24 to be described later is assembled to the frame 21) is suppressed.
[0015]
As shown in FIGS. 1 to 3, the handle main body 24 is a long one extending in the vehicle front-rear direction, like the frame 21, and is inserted into the insertion port 21 a at the front end side of the support body 24. 3 is formed with an engagement leg portion 24a that can be tiltably engaged, and an engagement arm portion 24b that is inserted into the insertion port 21b and engageable with the input portion 23a of the lever 23 is formed on the rear end side. Yes.
[0016]
In such a configuration, the handle main body 24 is engaged with the support portion 3 by the engagement leg portion 24a and supported by the frame 21 so as to be tiltable. The lever 23 is inserted between the support shafts 5 and 6 into the support holes 41a and 42a, and is positioned between the vertical walls 41 and 42 so that the input portion 23a is disposed in the insertion port 21b. The input portion 23a is positioned in the insertion port 21b and is engaged with an engagement arm portion 24b inserted into the insertion port 21b. Then, by tilting the handle body 24 with respect to the frame 21 around the support portion 3, the lever 23 is rotated by the engagement between the engagement arm portion 24b and the input portion 23a.
[0017]
As shown in FIGS. 1 and 2, the outer panel 1 of the vehicle door is also formed with an insertion port (not shown) similar to the insertion ports 21a and 21b of the frame 21, whereby the handle body 24 Can be attached to the frame 21 located inside the outer panel 1 from the outside of the outer panel 1. Further, a snap 27 for fixing a connecting member 26 such as a rod or cable connected to a door lock device (not shown) is fixed to the output portion 23b of the lever 23, and thus the lever 23 rotates. Thus, the door lock device is actuated via the connecting member 26.
[0018]
As shown in FIG. 1, the door outer panel 1 is formed with a recess 11 for facilitating the tilting operation of the handle body 24. The handle body 24 is formed with a cover portion 24c extending along the recess 11. The cover portion 24c covers the clearance between the outer panel 1 and the handle body 24 that is generated when the handle body 24 is tilted. ing. This prevents a finger from being pinched when the handle body 24 is tilted.
[0019]
As shown in FIGS. 1 and 2, the coil spring 25 is wound around a root portion 52 of one support shaft 5 of the lever 23. One end of the coil spring 25 is locked to the lever 23, and the other end is locked to the case 21. When the handle main body 24 is not tilted, the lever 23 is located at the initial position (solid line position in FIG. 3) due to the engagement between the input portion 23a and the engaging arm portion 24b. The clockwise rotation of the lever 23 shown in FIG. 3 due to the tilt of the handle body 24 causes the coil spring 25 to bend, thereby causing the coil spring 25 to generate a biasing force that biases the lever 23 toward the initial position. The lever 23 rotates within a predetermined stroke range up to the maximum stroke position (the two-dot chain line position in FIG. 3) against the urging force generated by the coil spring 25.
[0020]
The predetermined stroke position of the lever 23 where the tip end portion 51 of the one shaft portion 5 of the lever 23 and the fitting hole 41c of the vertical wall 4 of the frame 21 are fitted is the maximum of the lever 23 shown in FIG. It is a position just before the stroke position.
[0021]
Next, assembly of the door outside handle 2 having the above-described configuration will be described.
[0022]
First, with the coil spring 25 supported on one support shaft 5 of the lever 23, the lever 23 is rotatably supported on the frame 21, and both ends of the coil spring 25 are engaged with the frame 21 and the lever 23, respectively. . In this state, the lever 23 is rotated clockwise as shown in FIG. 3 to the predetermined stroke position while bending the spring 25, and the lever 23 is moved in the axial direction from the position shown by the solid line in FIG. 10 to the position shown by the one-dot chain line in FIG. (C direction in FIG. 10). As a result, the distal end portion 51 of the support shaft 5 is fitted into the fitting hole 41 c of the vertical wall 41 to restrict the rotation of the lever 23, and the lever 23 is held at a predetermined stroke position with respect to the frame 21.
[0023]
In this state, the handle main body 24 is configured such that the engaging leg 24 a and the engaging arm 24 b of the handle main body 24 are inserted into the insertion openings 21 a and 21 b of the frame 21 and the engaging leg 24 a is engaged with the support portion 3 of the frame 21. 24 is pushed into the frame 21 in the longitudinal direction (the direction D in FIG. 1 and FIG. 10 opposite to the direction C in FIG. 1 and FIG. 10 described above in the longitudinal direction of the vehicle and the axial direction of the lever 23). As a result, the engagement leg portion 24a of the handle body 24 engages with the support portion 21c of the frame 21, the engagement arm portion 24b of the handle body 24 engages with the input portion 23a of the lever 23, and the handle body 24 becomes the frame. 21 is assembled. At this time, since the lever 23 is held at a predetermined stroke position, the handle main body 21 is assembled to the frame 21 while being tilted to some extent with respect to the frame 21. Accordingly, when the handle body 24 is pushed into the frame 21 in the longitudinal direction, interference between the cover portion 24c of the handle body 24 and the outer panel 1 of the vehicle door is avoided, and the assembling work is facilitated. Further, when the handle body 24 is tilted to some extent and assembled to the frame 21, the engagement between the input portion 23a of the lever 23 and the engaging arm portion 24b of the handle body 24 is also ensured.
[0024]
When the handle main body 24 is assembled to the frame 21, the lever 23 is pushed in the axial direction (D direction in FIGS. 1 and 10) simultaneously with the engagement arm portion 24b engaging the input portion 23a of the lever 23. Is moved in the opposite axial direction (direction D in FIGS. 1 and 10). At this time, the direction in which the handle body 24 is assembled (direction D in FIGS. 1 and 10), the end portion 51 of the support shaft 5 of the lever 23, and the fitting hole 41c of the vertical wall 41 of the frame 21 are released. (D direction shown in FIGS. 1 and 10) coincides with the movement of the lever 23 in the axial direction (D direction shown in FIGS. 1 and 10) by attaching the handle body 24 to the frame 21. 51 is released from the fitting hole 41c. As a result, the holding of the lever 23 at the predetermined stroke position is released, and as a result, the engagement arm portion 24b of the handle body 24 and the input portion 23a of the lever 23 are engaged.
[0025]
【The invention's effect】
According to the present invention, the fitting shaft formed in the lever is fitted into the fitting hole formed in the frame, and the lever is held at a position rotated by a predetermined amount from the initial position in the middle of the entire stroke range. As a result, it is possible to improve the ease of assembly of the handle body to the frame, and to prevent the assembly failure of the lever and the handle body. Furthermore, since the lever is held by fitting the fitting hole formed in the frame and the fitting shaft formed in the lever, there is no increase in the number of parts and the cost is advantageous.
