  In the conventional door handle apparatus 100, since the push switch 120 which protrudes from the handle cover 110 is provided, there is a problem that the handle cover 110 which is streamlined and excellent in design is ruined.

  In order to solve such a problem, for example, it is conceivable to form a stepped surface recessed inward on a part of the handle cover 110 and attach the push switch 120 to this part.

  In such a case, if the push switch 120 is provided in a nearly flat portion near the center in the longitudinal direction of the handle cover 110, a streamlined handle can be provided even if the push switch 120 having a substantially flat top surface is attached as in the prior art. The appearance of the cover 110 is not impaired.

  However, since the door handle device 100 is usually designed to operate the push switch 120 with the thumb holding the handle, the push switch 120 is provided near the end of the handle cover 110. For this reason, when the push switch 120 having a substantially flat upper surface is attached, a step difference between the streamlined handle cover 110 and the upper surface of the button 121 is conspicuous as shown in FIG.

  If the upper surface of the button 121 is formed as an inclined surface along the curved surface 112 of the handle cover 110 as shown in FIG. 9A, the appearance will not be impaired, but this time, the following problems will occur. .

  That is, when the user operates the push switch 120 with a finger, as shown in FIG. 9B, the upper end of the inclined surface of the button 121 is easily pushed, and as a result, the button 121 is not inclined with respect to the finger. By moving, the lower surface of the button 121 is pushed obliquely with respect to the tact switch 122 (see FIG. 9C), so that the tact switch 122 is touched and damaged, and the durability of the push switch 120 decreases. .

  Therefore, an object of the present invention is to provide a door handle device that improves the durability of a push switch without impairing the appearance of a streamlined handle cover.

  Hereinafter, embodiments of the present invention will be exemplarily described based on the drawings. However, the material, shape, relative arrangement, and the like of the component parts described in this embodiment are not intended to limit the scope of the present invention to that unless otherwise specified.

(First embodiment)
As shown in FIGS. 1 and 2, the door handle device 1 of this embodiment includes a door handle 10 and a push switch 30 that are mounted on a door (not shown).
The door handle 10 is attached to the outside of the vehicle door and has a resin or metal handle member 11 that serves as a design surface outside the vehicle.

  The handle member 11 includes a curved surface 12 that is curved outward in the thickness direction of the door, a step surface 13 that is adjacent to the curved surface 12 and that is recessed inward in the thickness direction of the door, and an opening hole provided in the step surface 13. 14. The step surface 13 is provided in the vicinity of one end of the handle member 11 in the longitudinal direction.

  The push switch 30 is for locking or unlocking the door, and includes a button 40, a switch substrate 50, a tact switch 60, and a case 70, and a part of the button 40 projects from the opening hole 14. It is attached to the handle member 11 as described above.

As shown in FIG. 3, the button 40 is integrally formed of a soft resin, and has an upper wall portion 41 protruding outward from the opening hole 14 of the handle member 11 and a substantially columnar shape protruding below the upper wall portion 41. The pressing portion 42, an elastically deformable thin buckling portion 43 extending in a taper shape around the pressing portion 42 toward the lower portion of the upper wall portion 41, and an opening portion extending downward from the lower end portion of the buckling portion 43. And a base portion 45 having 44.
In addition, although the base part 45 of this example is comprised so that waterproofness can be ensured by uneven | corrugated fitting with the case 70, when the door handle apparatus 1 is attached to indoor doors, such as an apartment, Such a base portion 45 is not always necessary.

  The upper surface of the upper wall portion 41 of the button 40 is formed as an inclined surface 46 along the curved surface 12 of the handle member 11 so as not to impair the streamlined appearance of the door handle 10 (see FIG. 2). .

  The switch substrate 50 has an insulating property and is fixed to a stepped portion 47 provided in the vicinity of the opening 44 of the button 40.

  The tact switch 60 is fixed on the switch board 50 and disposed in the button 40. The tact switch 60 includes an operation portion 62 having a substantially rectangular pressing surface 61 that is substantially perpendicular to the thickness direction of the door, and a main body portion 63, and the pressing surface 61 is disposed opposite to the lower surface of the pressing portion 42. ing.

When the button 40 is pushed downward, the pressing surface 61 of the operating portion 62 is pushed downward by the pressing portion 42, a click feeling is obtained, and a contact point (not shown) is turned on. When the pressing force of the operation unit 62 is removed, the original state is restored and the contact is turned off.
The on / off signal of the tact switch 60 is transmitted to the outside through a lead wire (not shown) connected to the lower surface of the switch board 50.

  The case 70 is formed in a substantially square cylindrical shape by a hard resin, and is fixed to the outer periphery of the button 40 by the engagement between the groove portion 48 outside the base portion 45 of the button 40 and the inner collar portion 71 inside the case 70. The case 70 of this example is arranged on the outer periphery of the base portion 45 of the button 40 so that the structure of the soft button 40 is maintained. However, the base portion 45 of the button 40 is formed of a hard material. In some cases, such a case 70 is not always necessary.

In the door handle device of the present embodiment, since the upper surface of the upper wall portion 41 of the button 40 is formed as an inclined surface 46 along the curved surface 12 of the handle member 11, the streamlined appearance of the door handle 10 is impaired. However, when the user presses the button 40, the upper end side of the inclined surface 46 is easily pressed strongly.
When the upper end side of the inclined surface 46 is strongly pressed, the upper wall portion 41 moves so as not to be inclined with respect to the flat surface of the user's finger, so that the lower surface of the pressing portion 42 is formed in parallel with the pressing surface 61. Then, the pressing portion 42 pushes the pressing surface 61 obliquely, hits the tact switch 60, and the durability of the push switch decreases.

Therefore, in the present embodiment, an inclined surface 49 that is substantially parallel to the upper surface of the upper wall portion 41 of the button 40 is formed on the lower surface of the pressing portion 42 of the button 40. By forming such an inclined surface 49, when the user presses the button 40, the pressing portion 42 of the button 40 turns on the tact switch 60 in a state where the inclination of the tact switch 60 with respect to the pressing surface 61 is reduced. Therefore, the pressing portion 42 is hardly damaged and the durability of the push switch is improved.
Hereinafter, this point will be described with reference to FIG.

  FIG. 4A shows a state where the button 40 is not pressed. In this state, the buckling portion 43 of the button 40 is not elastically deformed and the tact switch 60 is off.

  FIG. 4B shows a state where the button 40 is being pressed. Since the button 40 has the inclined surface 46 on the upper wall portion 41, when the user presses the button 40 with the finger 2, the upper end of the inclined surface 46 is easily pressed more strongly. On the other hand, since the buckling portion 43 of the button 40 has the same shape over the entire circumference, the buckling portion 43 on the upper end side of the inclined surface 46 is more elastically deformed. Therefore, the inclined surface 46 moves along the plane of the user's finger 2 so as to be substantially perpendicular to the thickness direction of the door (the vertical direction in FIG. 4).

  When the button 40 is further pressed, as shown in FIG. 4C, the pressing portion 42 having the inclined surface 49 substantially parallel to the inclined surface 46 of the upper wall portion 41 is substantially perpendicular to the thickness direction of the door. The tact switch 60 is turned on with a small inclination with respect to the pressing surface 61. The opening hole 14 is set to a predetermined size so that the outer periphery of the upper wall portion 41 does not hit the handle member 11 even when the tact switch 60 is turned on as described above.

  Thereafter, when the user releases the finger 2 from the button 40, the button 40 returns to the original position by the elastic restoring force of the buckling portion 43, and the tact switch 60 is turned off.

As described above, the upper surface of the upper wall portion 41 of the button 40 of the door handle device of the present embodiment is inclined with respect to the pressing surface 61 of the tact switch 60 and is inclined along the curved surface 12 of the handle member 11. The lower surface of the pressing portion 42 of the button 40 is formed as an inclined surface 49 that is substantially parallel to the upper surface of the upper wall portion 41 of the button 40.
Thereby, even if the push switch 30 protruding from the stepped surface 13 that is recessed adjacent to the curved surface 12 of the handle member 11 is attached, the step difference between the streamlined appearance of the handle cover 11 and the upper surface of the button 40 is conspicuous. No, the streamlined appearance of the door handle 10 is not impaired.
Further, even when the user presses the button 40 and the button 40 moves along the plane of the user's finger 2, the pressing surface 61 of the tact switch 60 can be pressed by the surface. The bottom surface is hardly damaged, and the durability of the push switch 30 is improved.

The rising inclination angle with respect to the pressing surface 61 of the tact switch 60 is small.

  Specifically, the rising inclination angle α of the buckling portion 43a on the upper side of the inclination of the button 40 with respect to the pressing surface 61 of the tact switch 60 is smaller than the rising inclination angle β of the buckling portion 43b on the lower side of the inclination of the button 40, For example, α = 30 degrees and β = 45 degrees.

  Therefore, the door handle device of the present embodiment can obtain the same effects as those of the first embodiment, and when the user presses the button 40, the buckling portion 43a on the upper side of the upper wall portion 41 of the button 40 is inclined. The button 40 can more reliably push the pressing surface 61 of the tact switch 60 with the surface, the bottom surface of the button 40 is hardly damaged, and the durability of the push switch is improved.
