[Problems to be solved by the invention]
By the way, this kind of door handle grip is operated to pull the handle grip from the door in order to release the door. As a result of this operation, the door handle grip undergoes deflection deformation centering on the grip portion of the operator. Due to this bending deformation, a force is generated to move between the shell and the front edge in a locked relationship with each other, and as a result, the members rub against each other. The relative rubbing of the sliding contact surface becomes a surface in the form of an abnormal sound when the door handle grip is operated. This abnormal sound may cause the user to feel that the handle grip is not properly assembled, or may make the operation feeling itself uncomfortable.
[0005]
Therefore, the present invention has been made in view of the above problems, and an object of the present invention is to propose a new technical means for preventing the door handle grip from generating abnormal noise.
[0006]

The technical means taken in order to solve the above-described problem is a door handle grip including a handle body and a handle cover combined with the handle body, and the handle at a portion where the handle cover and the handle body abut. At least one of the cover and the handle body is provided with a rough surface portion.
[0007]
The rough surface portion preferably includes a plurality of concave and convex portions, and further, a contact portion where the handle body and the handle cover abut via the rough surface portion, and a contact portion where the handle cover and the handle body abut. It is preferable that a clearance defined between the handle cover and the handle body is provided between the handle cover and the handle body.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0009]
FIG. 1 is a cross-sectional view showing a configuration of a door handle grip 10 (door handle grip) according to an embodiment of the present invention.
[0010]
As shown in FIG. 1, the door handle grip 10 includes a handle body 11 (handle body) and a handle cover 12 (handle cover 12) combined with the handle body 11. The handle body 11 is made of resin, and its surface is painted. Similarly, the handle cover 12 is made of resin, and the surface thereof is painted or plated for decorativeness and design. An accommodating portion 13 is formed in the handle main body 11 so as to open in a direction away from a door (not shown) (upward in FIG. 1), that is, to extend in the longitudinal direction of the handle main body 11. The handle cover 12 covers the opening of the accommodating portion 13. That is, the handle body 11 and the handle cover 12 are combined so as to form a hollow space (accommodating portion 13) therein. The housing part 13 houses an electronic component device 14 (for example, a transmission / reception antenna, a capacitance type human sensor, etc.).
[0011]
The handle body 11 itself has a long shape and includes arms 11a and 11b. The arm 11a is formed at one end of the handle body 11 in the longitudinal direction (left side in FIG. 1). The arm 11a extends into the door (lower side in FIG. 1) through an outer panel opening (not shown) of the door, and is supported by a frame (not shown) provided in the door.
[0012]
On the other hand, the arm 11b is formed at the other end of the handle body 11 in the longitudinal direction (on the right side in FIG. 1). Similarly to the arm 11a, the arm 11b extends into the door through the opening of the outer panel, and is supported by a frame (not shown) provided in the door.
[0013]
The handle cover 12 is fixed to the handle main body 11 via connecting means such as a screw at both ends in the longitudinal direction. Further, as shown in FIG. 2, between the handle body 11 and the handle cover 12, a plurality of locking holes 11c (only one is shown in FIG. 1) formed in the handle body 11 and the handle cover 12 are provided. There are provided locking means 15 (shown in FIG. 2) comprising a plurality of locking claws 12a (only one is shown in FIG. 1). The locking means 15 makes the handle cover 12 fixed to the handle body 11 more stable.
[0014]
In the state in which the handle body 11 and the handle cover 12 are fixed as described above, the handle cover 12 is connected to the contact portion 11d of the handle body 11 via the mating surface 12b (rough surface portion) that is processed into a textured shape. It is in a contact state. That is, the handle body 11 includes a contact portion 11 d that contacts the handle cover 12, and the handle cover 12 includes a mating surface 12 b that contacts the handle body 11. The abutting portion 16 between the mating surface 12b and the contact portion 11d will be described with reference to FIGS.
[0015]
FIG. 3 is a cross-sectional view taken along line III-III in FIG. In the abutting portion 16 between the handle main body 11 and the handle cover 12, the mating surface 12b of the handle cover 12 and the contact portion 11d of the handle main body 11 are in contact with each other. An enlarged view of the abutting portion 16 corresponds to FIGS. 4 and 5.
[0016]
FIG. 4 shows an enlarged view of one of the aforementioned abutting portions 16. As shown in FIG. 4, in the abutting portion 16 between the handle body 11 and the handle cover 12, the handle cover 12 is in contact with the handle body 11 via a mating surface 12 b that is processed into a textured shape. 11d is in contact. That is, the mating surface 12b is composed of a plurality of irregularities. As a result, in the abutting portion 16, the contact portion 11d and the mating surface 12b are in contact with each other at an infinite number of points.
[0017]
On the other hand, when the mating surface 12b is a smooth surface that is not subjected to textured processing or the like, for example, only normal coating, the abutting portion 11d and the mating surface 12b are abutted by both surfaces. It is in a state. However, in this case, the quality of the shape accuracy and the paint state of the individual handle main body 11 and handle cover 12 is not completely uniform. It is practically difficult. Therefore, in the abutting portion 16 between the handle main body 11 and the handle cover 12, the mating surface 12b and the abutting portion 11d are not uniformly in contact with each other over the entire surface, and the surface pressure is partially biased. In other words, it is in a state of contact per piece. This uneven surface pressure may cause noise when the door handle grip is operated. The mechanism of abnormal noise generated by the door handle grip operation will be described below.
[0018]
When the door is operated, the door handle grip 10 is pulled in a direction away from the door (upward in FIG. 1). Along with this operation, the door handle grip 10 is also deformed by bending in the direction away from the door (upward in FIG. 1). Due to this bending deformation, a force for moving each other acts between the mating surface 12b of the handle cover 12 and the contact portion 11d of the handle body 11 which are in contact with each other.
[0019]
When the mating surface 12b is not subjected to a textured process, as described above, the mating surface 12b and the contact portion 11d are not in a state where the entire surface is in uniform contact, and the surface pressure is partially biased. In contact. Here, in the part where the surface pressure is high, the mating surface 12b and the contact part 11d are pressed against each other, that is, in a state where they are difficult to move. When the mating surface 12b and the abutting portion 11d move with each other in a state where they are strongly pressed against each other, abnormal noise is generated as the members are rubbed.
[0020]
On the other hand, in the present embodiment, as described above, the handle cover 12 is in contact with the contact portion 11d of the handle main body 11 via the mating surface 12b that has been processed into a crimped shape. The mating surface 12b, which is processed into a crimped shape, makes the mating surface 12b and the abutting portion 11d abutted by innumerable points, and the uneven surface pressure in the abutting state is alleviated. Yes. That is, the mating surface 12b and the contact portion 11d are in a state where they can easily move. Therefore, when a force to move each other between the mating surface 12b and the contact portion 11d is applied due to the deflection deformation during the operation of the door handle grip 10, the members are rubbed with each other, but the surface pressure is uneven. Since it is easy to move to each other by relaxation, no abnormal noise occurs due to rubbing. In the present embodiment, the rough surface portion is formed on the handle cover 12 side, but the rough surface portion may be formed on the handle body 11 side.
[0021]
Next, means for further improving the quality of the door handle grip 10 in addition to preventing the occurrence of abnormal noise will be described.
[0022]
FIG. 5 is an enlarged view of one of the butting portions 16 as in FIG. 4, and particularly corresponds to a view paying attention to the coating applied to the handle main body 11. As shown in FIG. 5, a painted surface 17 is formed on the surface of the handle main body 11. Generally, in a recessed part such as the contact part 11d of the handle body 11, coating or the like tends to accumulate. For example, the corners of the recessed part such as the corners 17a and 17b shown in FIG. It is assumed that the paint will accumulate on the part. In this case, depending on the shape of the handle cover 12, when the handle cover 12 is fixed to the handle body 11, the handle cover 12 interferes with the corner portions 17 a and 17 b and is fixed to the handle body 11 in a normal state. There is a risk that it will not be possible. For example, when the handle cover 12 is in a floating state with respect to the handle main body 11, it is not preferable in design.
[0023]
As shown in FIG. 5, the handle cover 12 has a chamfered shape continuously from the mating surface 12b so that interference with the corner portion 17b can be avoided even when the paint is accumulated like the corner portion 17b. An escape portion 12c is formed. The escape portion 12c is configured to form a gap with the contact portion 11d of the handle body 11. The relief portion 12c can prevent the handle cover 12 from being lifted with respect to the handle body 11 even when paint or the like is accumulated like the corner portion 17b. Here, the relief portion 12c does not necessarily have a chamfered shape, and may be, for example, a curved shape capable of avoiding interference with the corner portion 17b.
[0024]
In the present embodiment, the handle body 11 is located on the side close to the door (lower side in FIG. 1), the handle cover 12 is located on the opposite side (upper side in FIG. 1), and the vertical direction in FIG. However, it is not limited to this. The position may be reversed, or the handle body 11 and the handle cover 12 may be combined in the vertical direction on the paper surface of FIG.
[0025]
【The invention's effect】
According to the present invention, the rough surface portion of the handle cover comes into contact with the handle body. Accordingly, the handle cover and the handle main body can easily move relative to each other. That is, it is possible to alleviate the uneven surface pressure of the surface where the handle cover and the handle main body abut. As a result, it is possible to effectively prevent the generation of noise due to the door handle grip operation.
