Abstract

The door handle device of a vehicle is provided with: a handle base disposed along the rear surface of a door panel; and an operation handle that is coupled to the handle base. The handle base has hook-shaped pressing portions that ride on a protruding portion provided to the oppossed side edges along the sliding direction of a mounting opening provided to the door panel accompanying a sliding operation along the door panel; a panel-abutting portion that sandwiches the door panel in cooperation with the hook-shaped pressing portions; and an elastic locking piece that restricts the rearwards motion of the handle base by resilient locking to the center of a rear end edge of the mounting opening, and restricts removal of the hook-shaped pressing portions from the protruding portion.

First claim

The invention claimed is:

1. An attachment structure of a handle base disposed on a rear surface of a door panel and supporting an operation handle that is mounted from a front surface side of the door panel, the attachment structure of the handle base comprising:
a mounting opening provided in the door panel for temporarily fixing the handle base therein;
a pair of protruding portions provided in a peripheral edge of the mounting opening;
hook-shaped pressing portions that are provided in the handle base and that ride on the pair of protruding portions; and
a locking piece that is provided in the handle base and that abuts against the peripheral edge of the mounting opening at a position of the peripheral edge of the mounting opening that does not define the pair of protruding portions,
wherein the handle base is temporarily fixed to the door panel by the hook-shaped pressing portions and the locking piece.

2. The attachment structure of the handle base according to claim 1 , wherein, during a sliding operation in which the handle base is translated relative to the door panel in a slide direction, the hook-shaped pressing portions are adapted to ride on the protruding portions along an edge of each mounting opening on which the protruding portions are formed, and
the locking piece includes an elastic locking piece that is provided in the handle base and is adapted to enter the mounting opening on a leading side of the mounting opening during the sliding operation in the slide direction,
such that
detachment of the handle base in a panel plate-thickness direction is restricted by sandwiching the door panel with the hook-shaped pressing portions and a panel-abutting portion of the handle base to a rear surface of the peripheral edge of the mounting opening and
movement of the handle base in a slide retreat direction opposite the slide direction is restricted while the movement of the handle base in the slide direction is allowed by the elastic locking piece within a range where the hook-shaped pressing portions ride on the protruding portions.

3. The attachment structure of the handle base according to claim 2 , wherein a rear end edge of a front mounting opening has a substantially U shape and
the elastic locking piece is formed at a position on the handle base where the elastic locking piece can be locked to a center of the rear end edge of the front mounting opening.

4. The attachment structure of the handle base according to claim 3 , wherein the hook-shaped pressing portions have longitudinal dimensions that are slightly smaller than gaps between the rear end edge of the front mounting opening and rear ends of the protruding portions and
the elastic locking piece is formed to have a width dimension that is slightly smaller than a dimension between the hook-shaped pressing portions to be opposed to each other.

5. The attachment structure of the handle base according to claim 1 , wherein, during a sliding operation in which the handle base is translated relative to the door panel in a sliding direction,
the hook-shaped pressing portions are adapted to ride on the protruding portions provided at the opposed side edges in a sliding direction of the mounting opening in the door panel,
a panel-abutting portion of the handle base is adapted to sandwich the door panel in cooperation with the hook-shaped pressing portions and
the locking piece is adapted to be resiliently locked to a center of a rear end edge of the mounting opening to restrict rearward movement of the handle base and to restrict detachment of the hook-shaped pressing portions from the protruding portions.

6. A handle base attachment method for attaching, on a rear surface of a door panel, a handle base supporting an operation handle that is mounted from a front surface side of the door panel, the handle base attachment method comprising:
providing a mounting opening for temporarily fixing the handle base to the door panel,
providing a pair of protruding portions on a peripheral edge of the mounting opening,
providing, on the handle base, hook-shaped pressing portions that ride on the pair of protruding portions and a locking piece abutting against the peripheral edge of the mounting opening at a position of the peripheral edge of the mounting opening that does not define the pair of protruding portions, and
temporarily fixing the handle base to the door panel by the hook-shaped pressing portions and the locking piece.
