Description

[Detailed Description of the Invention] This invention relates to an improvement in the structure of a door lock knob used in an automobile door.

As a conventional door lock knob device used in the opening/closing knob section A of the automobile door shown in FIG. 1, there is, for example, one shown in FIG. 2.

The knob 1 has a head 1a that can be moved up and down by hand, and a leg 1b at the bottom.
A threaded portion (not shown) that is screwed into a threaded portion 3a formed at the upper end of the rod 3 is formed at the center of the lower surface of the leg portion 1b.

The escutcheon 2 has a through hole 2b formed in the center of the base 2a through which the leg 1b of the knob 1 can be inserted freely, and a hook 2c that engages with a door panel hole on the bottom surface of the base 2a. There is.

Said rod 3 leads inside the door to a locking device.

For example, see Japanese Utility Model Application Publication No. 55-129956.

However, in such a conventional door lock knob structure, since the knob 1 and the escutcheon 2 are separate parts, there is a problem that the installation process is complicated and takes too much time on the line.

This invention was made in view of these conventional problems, and aims to provide an automobile door lock knob structure that can be quickly installed.

This invention will be explained below based on the drawings.

FIG. 3 is a diagram showing one embodiment of this invention.

First, to explain the configuration, the door lock knob device has knob part 1.
The knob portion 10 and the escutcheon portion 20 are integrally molded from synthetic resin.

The knob part 10 consists of a head part 11 and a leg part 13 which extends from the lower surface 12 of this head part 11 and has a smaller diameter than the head part 11.
A groove 14 is formed in the lower surface of the holder, and a spring 30 made of metal is mounted in the groove 14.

The escutcheon part 20 consists of a base body 22 having a hole 21 formed in the center and a hook part 23 formed on the lower surface of the base body 22 and elastically engaged with the panel hole 41 of the door panel 40.

The knob part 10 and the escutcheon part 20 are the head part 1.
The base body 22 and the leg portions 13 are integrally formed at a thin wall portion 15 formed at the upper end of the hole 21 around the entire circumference or at several locations so that the lower surface 12 of the base body 22 is located above the upper surface 24 of the base body 22 by a certain length. connected.

As shown in FIG. 4, the spring 30 has a main body 31 bent into a U-shape, and has a plurality of triangularly cut claws 32 formed on both sides of the outer periphery, and a plurality of claws 32 cut and raised in a triangular shape on both sides of the inner periphery of the main body 31. A plurality of hanging pieces 33 are formed in a corner shape.

The tip of the claw 32 is inclined toward the end of the main body 31, and the tip of the hooking piece 33 is inclined toward the bottom surface 34 of the main body 31.

Next, the action will be explained.

The spring 30 is attached to the groove 14 of the knob portion 10 in advance.

That is, when the spring 30 is pressed and inserted into the groove 14 from the bottom surface 34 side, the claw 32 of the spring 30 is locked to the inner surface of the groove 14.

Since the claws 32 have resistance in the pulling direction, they are integrated without being easily separated.

Next, as shown in FIG. 3, the hook 23 is inserted into the panel hole 41.

As a result, the hook portion 23 is elastically bent and the panel hole 41
engage with.

Next, when the head 11 is lightly hit with a hammer or the like, the thin part 1
5 is cut and the knob portion 10 is pushed down.

As a result, the threaded portion 3a of the rod 3 as shown in FIG.
The latching piece 33 is engaged with the latching piece 33, and the tip of the latching piece 33 is fitted into the thread root of the threaded portion 3a, resulting in a locked state, and the knob portion 10 is integrated with the rod 3.

That is, the position of the knob part 10 is automatically determined by pushing down the knob part 10 until the lower surface 12 of the knob part 10 comes into contact with the upper surface 24 of the escutcheon part 20.

In addition, in order to remove the knob part 10 from the rod 3,
This can be done by rotating.

As explained above, according to this invention, the knob part and the escutcheon part are integrally molded by a thin wall part, so the number of parts is reduced, cost can be reduced, and the knob part can be simply pressed. Since the knob part and the escutcheon part can be easily separated by simply doing this, the assembly time can be significantly shortened.

Furthermore, as in the present embodiment, if the knob section is provided with a locking piece that engages with the threaded section of the rod, during assembly, only pressing work is required, eliminating the need for complicated adjustment work, thereby significantly improving work efficiency.
