Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to door handles, particularly door handles for automobiles.

A door handle for an automobile with a sliding plate includes a bracket that is fixed to a door panel of an automobile, and a handle body that is rotatably attached to the bracket. For example, Jikko 62-216
As shown in Japanese Patent No. 35, a bracket that also serves as an escutcheon is provided with a pair of rectangular holes and a pair of arm portions on the back surface of the bracket adjacent to these rectangular holes.

A circular through hole is provided at the tip of each arm portion. Further, the bracket is formed with a circular hole into which a key cylinder of the locking device is attached, if necessary.

Further, a pair of arm portions are integrally formed in the handle body, and a through hole is formed adjacent to the tip of each arm portion.

A connecting hole is drilled in one arm of the handle body,
A rod that is operatively connected to a locking device provided in the door is connected to this connecting hole via a connector. Pins are non-removably attached to the through holes of the arm portions of the bracket and the handle body, and the handle body is rotatably supported with respect to the bracket. The two adjacent arm portions of the handle body and the bracket are each pivoted by a pin. The handle body is pressed in a direction toward the door panel by a spring.

In the above structure, when the handle body is pulled up by hand, the handle body rotates outward around the pin, and the rod connected to the arm of the handle body moves downward, actuating the locking device and opening the door. can open the door. When you release your hand from the handle body, the spring automatically rotates the handle body toward the door panel and returns it to its original position.

When a pin is attached to a through-hole in an arm of a bracket and a handle main body in a manner that cannot be removed, conventionally, the pin is knurled to form a through-hole in an arm having an inner diameter slightly smaller than the diameter of the pin. A pin was pressed into the hole. Therefore, a process of knurling the pin and a process of press-fitting it into the hole in the arm were required. These processes require processing jigs,
When two pins were press-fitted into the holes in the arm portion, the manufacturing time of the automobile door handle increased. In addition, even if the pin was press-fitted into the hole in the arm part, there was a risk that the pin would fall off due to processing accuracy errors and vibrations of the car. Therefore, this invention was developed to provide an automobile door with a small number of parts and easy to manufacture. The purpose is to provide a handle.

A door handle for an automobile according to the present invention includes a bracket fixed to a door panel of a vehicle body, and a handle body rotatably supported by the bracket. A pair of arm portions are provided on each of the bracket and the handle body, and a pair of shaft portions are formed coaxially and integrally with the arm portions of the bracket. The pair of arm portions of the handle body are formed with an inner spacing that is smaller or an outer spacing that is larger than the spacing between the free ends of the pair of shaft portions, and at least one arm portion that is integrally provided on the bracket and the handle body has elasticity. The free end of the shaft portion is fitted into a hole formed in each arm portion of the handle body, and the handle body is urged against the bracket by a spring installed between the bracket and the handle body.

According to this invention, when manufacturing an automobile door handle,
The shaft portion formed on the arm portion of the bracket can be fitted into the hole of the arm portion formed on the handle body with one touch by a snap action. After assembly, the shaft part is molded integrally with the bracket, so it will not fall off.
