Abstract

A vehicle door handle device includes a handle base that is fixed to a door panel back surface of a vehicle, an operating handle that is linked to the handle base from a door front surface side to be rotatable around a rotation center, a stopper protrusion that is provided in any one of the operating handle and the handle base, and an engaged portion that is provided in the other one of the operating handle and the handle base.

Claims (35)

1. A vehicle door handle device comprising:

a handle base that is fixed to a door panel back surface of a vehicle;

an operating handle that is linked to the handle base from a door front surface side to be rotatable around a rotation center;

a stopper protrusion that is provided in any one of the operating handle and the handle base; and

an engaged portion that is provided in the other one of the operating handle and the handle base,

wherein along with sliding of the operating handle to a rotation center side, the stopper protrusion and the engaged portion are elastically engaged with each other so that movement of the operating handle to a rotation distal end side is restricted,

wherein a hinge protrusion protrudes from an end portion of the operating handle on the rotation center side,

wherein the handle base includes a hinge restriction portion,

wherein the hinge restriction portion includes a top wall restricting movement of the hinge protrusion in a door panel direction and an abutting wall of the hinge protrusion,

wherein the hinge protrusion abuts into the hinge restriction portion in an internally contact manner,

wherein in a state that the hinge protrusion abuts against the hinge restriction portion, an inner center of the hinge restriction portion fits to the rotation center of the operating handle,

wherein a gap that keeps a non-contact state of the stopper protrusion and the engaged portion during a translational movement of the operating handle to outside of a door is provided between the stopper protrusion and the engaged portion, and

wherein when an operating force for opening the door is applied to the operating handle and a moving force to the outside of the door is applied to the rotation center of the operating handle, the gap absorbs the movement force.

2. The vehicle door handle device according to claim 1 ,

wherein the engaged portion is formed to have an opening.

3. The vehicle door handle device according to claim 1 ,

wherein the stopper protrusion is positioned at the rotation center of the operating handle.

4. The vehicle door handle device according to claim 1 ,

wherein in a state that one of the stopper protrusion and the engaged portion as a moving element moving in an engaged and disengaged direction, engages with the other one of the stopper protrusion and the engaged portion as a receiving element along with a sliding movement of the operating handle to the rotation center side, in a press-contact portion between the moving element and the receiving element along with the sliding of the operating handle to the rotation center side, the engaged and disengaged direction of the moving element is substantially perpendicular to an operation line direction of the operating handle on the receiving element in an engagement releasing direction.

5. The vehicle door handle device according to claim 1 ,

wherein the stopper protrusion protrudes from the operating handle,

wherein an elastic wing piece that is cantilevered and positioned along a sliding operation direction of the operating handle is formed in the handle base,

wherein the elastic wing piece includes a fixed end in an operation distal end direction during a slide operation of the operating handle to the rotation center side,

wherein the elastic wing piece includes a stopper abutting piece at a free end,

wherein the stopper protrusion presses and contacts to the stopper abutting piece during the sliding movement of the operating handle to the rotation center side and the elastic wing piece is elastically deformed to allow passage of the stopper protrusion, and

wherein the engaged portion is formed in the elastic wing piece and elastically engages with the stopper protrusion due to an elastic restoration operation of the elastic wing piece after the passage of the stopper protrusion.

6. The vehicle door handle device according to claim 5 ,

wherein an engagement releasing portion in which the elastic wing piece is operated to release an engagement of the engaged portion, extends from the stopper abutting piece.

7. The vehicle door handle device according to claim 1 ,

wherein the top wall includes upper and lower edges that are linked to upper and lower wall surfaces of a distal end portion of the handle base, and

wherein the top wall includes a front end edge that is linked to a front end wall surface of the handle base.

8. The vehicle door handle device according to claim 1 ,

wherein the stopper protrusion is formed as a pin-shaped member that advances and retreats by being biased in a protruding direction by a spring.

9. The vehicle door handle device according to claim 1 ,

wherein the gap softens an impact force to the outside of the door.
