Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an operating knob for a lever-operated mirror device, that is, a knob fixed to a mirror tilting lever on the side of the mirror device.

This type of mirror device is located on the outside of the door of the car body, and the lever for tilting the mirror extends into the passenger compartment, and a knob is provided at one end of the lever. It is used in automobile door mirrors that are operated by the driver.

The conventional example of this kind of thing is the first one.
This is a knob a as shown in the figure.

This knob a has a lever-fitting cylindrical part C protruding from the back surface of the approximately central part of the elongated hollow-shaped main body part, and a grommet d can be attached to the surface thereof in the direction of the arrow in the figure.

This grommet d seals the opening of the main body and is attached so that the head of the screen knee for fixing the lever to the lever cannot be seen from the surface. It is attached to the main body by forming claws e and engaging with engaging step portions f provided at both ends of the main body.

However, this type of attachment of the grommet d is possible because the lever-fitting cylindrical portion C protrudes from the center of the main body and has a roughly T-shape. In the case of an L-shape in which the lever-fitting cylindrical portion C' protrudes from one end of the part, an engaging stepped portion f can be formed on the other side, but the lever-fitting cylindrical portion C' It is difficult to form an engaging step on the side.

That is, in the L-shaped one shown in FIG. 2, if the upper and lower parts of the mold are cut out, a step cannot be formed inside the fitting cylinder part ♂.

Additionally, it is possible to create a step by making a hole in the mating cylinder, but in that case, a complicated mold using a slide core is required, and the hole is made on the surface, which makes it difficult to design. Undesirable.

The reason why the knob is L-shaped as shown in Figure 2 is mainly due to design requirements, but if it is T-shaped, the grip part of the knob protrudes from the top and bottom, which is preferable for safety reasons. Therefore, it is desirable to have an L-shape in which the grip part protrudes only downward.

In view of the above circumstances, the present invention is a lever-operated mirror that can easily and securely attach a grommet even if the knob has a lever-fitting cylinder protruding near one end of the elongated main body. The purpose is to provide a knob for operating the device.

An example of implementing the present invention will be described below with reference to the accompanying drawings.

The illustrated example is an application of the present invention to an automobile mirror device, particularly a door mirror.

The door mirror in this example is arranged in a portion corresponding to the triangular window of the door.

The operating knob 1 of the present invention is fixed to a lever 21 for tilting the mirror located on the side of the mirror device 2, as shown in FIG.

The main body 11 of the knob 1 has a generally elongated shape, and a cylindrical portion 12 for lever fitting protrudes from near one end 1a of the main body 11.

The knob 1 also includes a grommet 13 that is attached to the surface of the main body 11.

In the present invention, the grommet 13 is provided with retaining protrusions 14 and 15 that are located opposite to each other with respect to a line along the longitudinal direction.

The line along the longitudinal direction is the X-axis in Fig. 4A and B, and in short, when the engaging protrusions 14 and 15 are placed with the longitudinal direction up and down as shown in the same figure, they will be located on the left and right. .

On the other hand, the main body portion 11 is formed with an engagement hole 16 for engaging the engagement projection 14.15, and the grommet 13 is connected to the main body by the engagement of the engagement hole 16 and the engagement projection 14.15. Part 1
Attach it to 1.

Since the present invention has the above-mentioned configuration, if the grommet is attached using the retaining claw as shown in Fig. 1, it will be attached only on one side and the attachment condition will be poor. Engagement protrusions 14.1 opposite with respect to the line
By adopting a configuration in which the grommet 5 is engaged with the engagement hole 16, the grommet 13 can be attached easily and reliably.

More specifically, the specific configuration of each part in the illustrated example is as follows.

As shown in FIG. 4, the grommet 13 has an elongated flat plate shape.

Since the grommet 13 forms a lid for the main body 11, it has a shape that fits the main body 11.

By installing the grommet 13, the main body 1
1 is covered, and the head of the screw 3 that fixes the main body 11 to the side of the mirror device 2 is also hidden.

The retaining protrusions 14 and 15 that protrude opposite each other have small flat parts 14a and 15a at their tips, as shown in FIG. Inclined surfaces 14b and 15b follow.

These two inclined surfaces 14b and 15b allow the engagement protrusions 14 and 1
The tip of 5 has a narrow wedge shape, and the main body 1
Press-fitting into the engagement hole 16 of No. 1 becomes easy.

A slight vertical flat part 14c on these inclined surfaces 14b and 15b,
Reversely inclined engagement surfaces 14d and 15d are continuous via 15c.

These engaging surfaces 14d and 15d are such that when the engaging protrusions 14, 15 are fully press-fitted into the engaging hole 16, the engaging protrusions 14, 15 elastically restore and engage with the periphery of the engaging hole 16. Since it serves as a stop for removal, it may be formed on the same surface as the engagement surface, but in order to ensure smooth engagement, it is inclined at about 30°.

The engaging surfaces 14d and 15d are further continuous with leg portions 14e and 15e, and the leg portions 14e and 15e are set to have elastic force.

Further, the peripheral edge 17 of the grommet 13 is formed into a tapered shape at an angle θ so that the main body 11 becomes thinner over almost the entire circumference, and its tip 17a is curved.

This is to make it easier to attach the grommet 13 to the main body 11.

Such a tapered portion is shown in Figure 4, opening, 2 and ho.

The main body part 11 has a lever fitting cylinder part 1 from one end part 1a thereof.
As mentioned above, the number 2 protrudes, and therefore, as shown in detail in FIG. 5, it has an oval shape on the side.

The engagement hole 16 is formed by drilling a square hole closer to the other end 1b.

As shown in detail in FIG.
15 is press-fitted from the direction of arrow A, this locking piece 16a
, 16b, each engagement surface 14d, 15 of the engagement protrusion 14.15
The installation is completed by the hooking of d, and removal is also prevented.

In this example, the lever fitting cylindrical portion 12 has a substantially rectangular cylindrical shape as shown in FIG. 5C, and has a square hole 12a formed therein.

An operating lever 21 on the side of the mirror device 2 is inserted into this square hole 12a.
is press-fitted, and the screw 3 is passed through the square hole 12a and screwed into the threaded hole of the lever 21, thereby assembling the mirror device 2 and the knob 1.

In this case, as shown in FIG. 3, a triangular plate 4 corresponding to a triangular window is interposed between the two 1 and 2, and partitions the two 1 and 2 into a vehicle interior and a vehicle exterior, respectively.

To fasten the screw 3, the screenie 3 is passed through the round hole 12b into which the screw 3 continuous in the direction of the grommet of the square hole 12a is fitted, and the hooker 31 of the screw 3 is brought into contact with the inner surface 11c of the main body 11.

The outer periphery of the main body part 11 is provided with serrations 11d to prevent it from slipping during operation.

FIG. 6 shows a perspective view of the entire knob 1 in which the main body portion 11 and the grommet 12 are assembled.

In this invention, the conventional example shown in FIG.
Since the engaging claws e are formed on both ends of the holder, it was difficult to hook the jig 6 (a screwdriver etc. can be used) as shown in Fig. 7 when removing after mounting. Since both ends are free, the jig 6 can be easily engaged and removed as shown in FIG. 8.

In FIG. 3, 5 a, 5 bg 5 c are screws for attaching the mirror device 2 to the triangular plate 4.

Although the mirror device 2 is installed outside the vehicle interior, the mirror 22 can be tilted as desired by operating the knob 1 inside the vehicle interior and tilting the operating lever 21 in each direction as schematically shown in FIG. They can be distant relatives.

A hole with enough space is provided in the triangular plate 4 for such tilting of the lever 21.

As detailed above, the operating knob of the lever-operated mirror device of the present invention includes a generally elongated main body, a lever-fitting cylinder protruding near one end of the main body, and a lever-fitting cylinder that is attached to the surface of the main body. The grommet is hollowed out from the grommet, and the grommet has engaging protrusions protruding from the grommet located opposite to each other about a line along the longitudinal direction, and the engaging protrusions are engaged with the engaging holes of the main body. Therefore, even in a configuration in which the lever-fitting cylinder portion protrudes from one end of the main body portion, it is possible to easily and reliably attach the grommet.

It should be noted that, as a matter of course, the present invention is not limited to the illustrated embodiment.
