BACKGROUND OF THE INVENTION
The present invention relates to a vehicle door handle device.
[0002]
[Prior art]
Conventionally, as this type of vehicle door handle device, a vehicle door handle device (first prior art) mounted on a Honda Accord / Torneo and a vehicle door handle disclosed in Japanese Patent Laid-Open No. 2000-179192 are disclosed. An apparatus (second prior art) is known.
[0003]
As shown in FIGS. 6 and 7, the first prior art has a first base 12 attached to a panel 11 of a vehicle door, and the panel 11 has a predetermined distance in the vehicle longitudinal direction from the first base 12. The vehicle door handle device 10 includes a second base 13 to be attached and a handgrip 20 having one end 21 in which a hole 28 is formed.
[0004]
In the vehicle door handle device 10, one end 21 of the handgrip 20 extends into the first base 12, and a pin 29 fixed to the first base 12 is inserted through the hole 28, whereby the first base 21. 12 is mounted so as to be rotatable around a pin 29. The other end 23 of the handgrip 20 extends into the second base 13 and is connected to a link mechanism (not shown) linked to a door lock mechanism (not shown).
[0005]
Thus, when the other end portion 23 of the handgrip 20 is pulled away from the panel 11, the handgrip 20 rotates about the pin 29 and the door opening operation is performed.
[0006]
The second prior art is a vehicle door handle device including a base attached to a panel of a vehicle door and a hand grip having one end formed in a U-shaped groove.
[0007]
In the vehicle door handle device according to the second prior art, one end portion of the handgrip extends into the base and is fitted into a shaft portion integrally formed with the base, thereby rotating around the shaft portion to the base. Mounted movably. The other end of the handgrip 20 extends into the base and is connected to a link mechanism (not shown) linked to a door lock mechanism (not shown).
[0008]
Thus, when the other end portion of the hand grip is caused to be pulled away from the panel, the hand grip rotates about the shaft portion, and the door opening operation is performed.
[0009]
[Problems to be solved by the invention]
In the vehicle door handle device 10 according to the first prior art, one end 21 of the hand grip 20 is attached to the first base with a pin 19. At this time, the extension of the one end portion 21 into the first base 12 and the insertion of the pin 29 are troublesome operations in the production process. For this reason, the abolition of the pin 29 was requested | required from the surface of the simplification of an operation | work and reduction of a number of parts.
[0010]
On the other hand, in the vehicle door handle device of the second prior art, one end portion formed in the U-shaped groove of the handgrip is fitted to the U-axis portion and attached to the base. Thereby, a pinless structure is realized. However, in the first prior art, the pin 29 serves as the center of rotation of the handgrip 20 and the one end 21 of the handgrip 20 when the handgrip 20 is displaced in the longitudinal direction of the vehicle is the first base. It also plays a role as a retaining means for preventing it from coming out of 12.
[0011]
Therefore, when the mounting structure of one end of the handgrip in the second prior art, that is, the pinless structure, is applied to the mounting structure of one end of the handgrip in the first prior art, the first prior art is divided into two in the vehicle longitudinal direction. In addition, since the first base and the second base are provided, a means for preventing the one end portion of the handgrip from coming off in the vehicle front-rear direction is lacking.
[0012]
Therefore, it is a technical object of the present invention to provide a pinless structure of a hand grip in a vehicle door handle device that includes first and second bases divided into two in the vehicle longitudinal direction.
[0013]
[Means for Solving the Problems]
The technical means taken in order to solve the above technical problem includes a first base attached to a panel of a vehicle door, and the first base attached to the panel at a predetermined interval in the vehicle front-rear direction. a second base, a handgrip having an end portion which is fitted to the shaft portion provided integrally with the U-shape is formed and the first base that opens in the extending direction, the first base projections provided on, and the than the one end of the handgrip provided on the other end, the shaft portion centered with said projections open in the direction the vehicle along and the arc locus exhibits a circular arc shape And a restricting means having a groove to be slidably inserted.
[0014]
In the technical means described above, when the other end of the hand clip is pulled away from the panel, the hand clip rotates about the shaft portion. Then, the protrusion and the groove are fitted in the vehicle front-rear direction by the restricting means by the insertion of the protrusion and the groove provided between the hand clip and the first base, so that the hand clip moves in the vehicle front-rear direction. Deviation is avoided. Therefore, one end portion of the hand clip does not come off from the shaft portion.
[0016]
DETAILED DESCRIPTION OF THE INVENTION
Specific examples of the present invention will be described with reference to the accompanying drawings.
[0017]
1 and 2, a vehicle door handle device 10 includes a first base 12 attached to a panel 11 of a vehicle door, and the panel 11 has a predetermined length in the vehicle front-rear direction (left-right direction in FIG. 1). A long base that extends in the vehicle front-rear direction so as to be close to the panel 11 so that one end thereof is close to the first base 12 and the other end is close to the second base 13. And a grip 20.
[0018]
At one end of the handgrip 20, an inverted L-shaped leg 21 is formed. The front end of the leg portion 21 is formed in a U shape and extends into the first base 12. The leg portion 21 of the hand grip 20 is fitted to a shaft portion 29 formed integrally with the inside of the first base 12, and the hand grip 20 is rotatable about the shaft portion 29. Yes. Further, an arm portion 23 is formed at the other end of the hand grip 20. The arm portion 23 extends into the second base 13 and is connected to a link mechanism 31 linked to the door lock mechanism 30. Thus, when the other end of the handgrip 20 is pulled away from the panel 11 (in FIG. 1, the direction away from the paper at a right angle / upward in FIG. 2), the handgrip 20 has a predetermined angular range around the shaft portion 29. The door is rotated (to be described later), and a door opening operation is performed.
[0019]
As shown in FIGS. 2 to 5, slots 40 are formed on both side surfaces of the leg portion 21 of the hand grip 20. A slope 41 and an arcuate depression (groove) 42 are formed on the bottom surface of the slot 40. Further, on each side wall facing both side surfaces of the leg portion 21 of the first base 11, a protrusion 44 disposed in the slot 40 is formed. Then, after fitting the leg portion 21 of the handgrip 20 to the shaft portion 29, the handgrip 20 is rotated in the direction in which the other end approaches the second base (the direction opposite to the above-described pulling direction) around the shaft portion 29. When moved, both protrusions 44 are arranged in both slots 40 and further over the corresponding slope 41 and into the arcuate recess 42 (so-called snap fit). In order to facilitate this overcoming, a slope 45 is formed on the tip surface of the protrusion 44.
[0020]
Thus, the leg portion 21 of the handgrip 20 has the shaft portion 29 in the space between the both side walls where the protrusion 44 of the first base 12 is formed (the space defined by a U-shaped portion in plan view). It is mounted so as to be rotatable as a center. In addition, the projections 44 are slidably fitted into the arc-shaped depressions 42 formed in the legs 21 of the hand grip 20. The center of curvature of the arc-shaped recess 42 is concentric with the shaft portion 29 so that the rotation of the handgrip 20 around the shaft portion 29 is not hindered. Thus, the projection 44 and the corresponding arcuate recess 42 form a concave-convex fitting in the vehicle front-rear direction, and even if the leg portion 21 of the handgrip 20 is about to come off from the shaft portion 29 in the vehicle front-rear direction, The concave / convex fitting between the projection 44 and the corresponding arcuate depression 42 prevents the handle grip 20 from coming off in the vehicle front-rear direction. In other words, each arcuate recess 42 corresponding to the protrusion 44 allows rotation about the shaft portion 29 of the handgrip 20, and the leg portion 21 of the handgrip 20 is detached from the shaft portion 29 in the vehicle front-rear direction. It constitutes a regulating means for making a stop.
[0021]
When the U-shaped leg portion 21 of the handgrip 20 rotates around the shaft portion 29, the upper and lower limit positions are positions where the protrusions 44 engage with the upper and lower edges of the corresponding arc-shaped recess 42. It is determined by. As a result, even if a high load in the rotational direction acts on the handgrip 20, the handgrip 20 may come off in the rotational direction due to the engagement between the protrusion 44 and the upper and lower edges of the arcuate recess 42. There is no. That is, the arcuate recess 42 and the protrusion 44 also function as a means for defining the rotation range of the hand clip.
[0022]
Although specific examples of the present invention have been described above, the present invention is not intended to be limited to the specific examples described above, and any method / apparatus according to the gist of the present invention may be used.
[0023]
【The invention's effect】
As described above, in the vehicle door handle device according to the present invention, the pin as the rotation center portion is excluded as a conventional shaft portion integrally formed with the first base as the rotation center of the hand grip. Therefore, it is possible to reduce the number of parts and simplify the work associated therewith. Further, since the hand clip is prevented from coming off in the longitudinal direction of the vehicle body by a restriction means provided with a protrusion provided between the hand clip and the first base and a groove into which the protrusion is slidably inserted, the pin is eliminated. In other words, the problem of handgrip in the vehicle front-rear direction can be avoided by fitting the protrusions and grooves of the restricting means in the vehicle front-rear direction.
[0024]
If the restricting means is constituted by a groove formed on the handgrip side and having an arc shape centered on the shaft portion, and a protrusion formed on the first base side and slidably inserted into the groove, A restricting means can be obtained, and the turning range of the handgrip can be defined by the groove and the protrusion.
