BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an illuminated mirror unit installed in a sun visor for an automobile or the like. In particular, an erroneous lighting of a lamp when the unit is not used can be easily detected, and power is wasted. The present invention relates to an illuminated mirror unit that does not have any problem.

[0002]

2. Description of the Related Art Recently, sun visors for automobiles are provided with vanity mirrors and the like, and some sun visors with mirrors having high commercial value have been employed, and these tend to be frequently used particularly in luxury models.

[0003] Recently, sun visors equipped with an illuminated mirror unit provided with an illuminating device for illuminating a vanity mirror have become widespread. In particular, a convertible type passenger car or the like illuminates a room at night due to its structure. It is suitable for a type having no lighting equipment such as a room lamp.

Referring to FIGS. 6 and 7 as a conventional example of a sun visor provided with the above-mentioned illuminated mirror unit, the sun visor 1 is rotatably supported on the vehicle body via a rotation shaft 1a. , The sun visor 1 has a desired light-shielding area, and has a shape-retaining property and a moderate cushioning property. The sun visor 1 is provided substantially at the center of the front side of the sun visor 1 (the side facing the occupant when the sun visor is rotated). The illuminated mirror unit 2 is mounted.

[0005] The mirror unit 2 with illumination is
A vanity mirror 4 and a lighting device 5 are provided on a unit base 3.

Further, in consideration of usability, the lighting device 5 can be turned ON / OFF in cooperation with the opening / closing operation of the opening / closing lid 6. The movable-side conductor 5a is pressed downward by the cam piece that does not come into contact with the fixed-side conductor 5b, and the lamp 5c is turned on. When the opening / closing lid 6 is closed, the movable-side conductor 5a becomes its own. When the movable conductor 5a and the fixed conductor 5b are returned upward due to the spring property or are lifted upward by the cam mechanism, the contact between the movable conductor 5a and the fixed conductor 5b is cut off, and the lamp 5c is turned off.

[0007]

As described above, in the conventional mirror unit 2 with illumination, the movable conductor 5a is moved by opening / closing the opening / closing lid 6, and the lamp 5 is turned on.
Although the structure blinks c, the movable-side conductor 5a may be plastically deformed with long-term use,
Even though the lid 6 is closed and not in use, the movable conductor 5a and the fixed conductor 5b may come into contact with each other and the lamp 5c may be left in a lit state.

If the lamp 5c is left in an erroneously lit state for a long time, the battery of the vehicle runs out and wastes power, and the peripheral parts are thermally deformed due to the heat generated by the lighting of the lamp 5c. This may cause a problem such as causing a problem.

The present invention has been made in view of such circumstances, and in a mirror unit with illumination, in which a vanity mirror and an illumination device are attached to a unit base, wasteful consumption of power due to erroneous lamp lighting and peripheral parts. It is an object of the present invention to provide an illuminated mirror unit capable of preventing thermal deformation of the illuminated light and improving the reliability of the unit.

[0010]

In order to achieve the above-mentioned object, the present invention provides a vanity mirror and a lighting device provided on a unit base, and an opening / closing lid for covering a surface of the vanity mirror and the lighting device is opened / closed on the unit base. In the mirror unit with illumination, which is freely mounted and energizes the illumination device by opening and closing the opening / closing lid, an opening for detecting an erroneous lighting of the illumination device is set at a part of the opening / closing lid corresponding to the illumination device. Features.

Here, it is preferable to install the illuminated mirror unit close to the occupant on the auxiliary seat side.
It is often installed in the sun visor on the auxiliary seat side, but it can also be installed on the back side of the seat back for use by rear occupants.

For example, when installing a mirror unit with illumination on a sun visor, a concave portion for accommodating the mirror unit is formed on the installation surface of the sun visor, and a locking piece or the like is integrally formed on the back side of the unit base. It can be attached by conventional fixing means such as engaging in an attachment hole provided in the attachment surface of the sun visor.

The unit base is made of ABS resin, PP
A resin material made of an injection molded body of a synthetic resin such as a resin and having sufficient rigidity to support a vanity mirror and an illuminating device, and particularly having heat resistance, is preferable. Further, an opening / closing lid is attached to the unit base via a bearing so as to be openable and closable so as to cover the surface side of the vanity mirror and the lighting device.

The opening / closing lid which can be opened / closed to the unit base holds the open state and the closed state of the opening / closing lid by providing a click action mechanism in a bearing portion, and the lighting device by opening / closing the opening / closing lid. Is turned on and off.

For example, a fixed-side conductor and a movable-side conductor are arranged as a contact mechanism of the lighting device, a cam piece for pressing the movable-side conductor is provided on the lid, and the cam piece and the movable-side conductor are moved by opening and closing the lid. Then, a configuration in which the contact mechanism is turned on and off can be considered.

Further, the opening / closing lid is provided with an opening for detecting an erroneous lighting of the lighting device at a part of a portion corresponding to the lighting device, but this opening does not impair the design of the unit. Thus, it is desirable to be set at the terminal portion of the lid, and the opening may be provided in a frame-like groove that is edged along the periphery of the lid surface.

As is apparent from the above configuration, since the opening is provided at a part of the opening / closing lid corresponding to the lighting device, the conductor or the like may be plastically deformed and the lid may be closed regardless of the closed state. Even when the lighting device is left in a lighting state, light from the lamp leaks through the opening, so that the occupant can quickly detect an erroneous lighting of the lighting device.

Furthermore, when an opening is set in a groove that is trimmed along the periphery of the lid surface, the bottom of the groove looks darker than other parts, so that light leakage due to erroneous lighting of the lighting device is more reliable. Can be caught.

FIG. 3 is a front view, FIG. 3 is a cross-sectional view showing the configuration of the illuminated mirror unit, FIG. 4 is a front view showing another embodiment of the illuminated mirror unit installed in a sun visor for an automobile, and FIG. It is sectional drawing which shows the structure of a mirror unit.

An embodiment of the illuminated mirror unit according to the present invention will be described with reference to FIGS.

In the drawings, reference numeral 10 denotes a sun visor for an automobile installed on the occupant side of the auxiliary seat, which is formed by covering the surface of a sun visor core having shape retention and cushioning properties with a skin such as cloth. The one end of the substantially L-shaped rotating shaft 11 is inserted into the sun visor 10, and the other end of the rotating shaft 11 is inserted into the bracket 12 fixed to the vehicle body, so that the sun visor 10 is vertically and horizontally. It can rotate in any direction and can be positioned at any position.

An illuminated mirror unit 20 is mounted substantially at the center of the surface of the sun visor 10. The illuminated mirror unit 20 is a unit base 30 made of a heat-resistant synthetic resin such as ABS resin. A vanity mirror 31 is mounted on the front side, and a lighting device 32 is mounted on a side adjacent to the vanity mirror 31. An opening / closing lid 40 is mounted so as to open and close so as to cover the front surface of the unit base 30.

More specifically, the illuminating device 32 is composed of an illuminating lamp 33, a conductor 34 (movable-side conductor 34a, fixed-side conductor 34b) forming a contact mechanism, and an illuminating lens 35. FIG. This shows a state where the lens 35 has been removed.

The opening / closing lid 40 is attached to the upper edge of the unit base 30 via the bearings 41 on both side edges so as to be openable and closable. The bearing 41 has a click action mechanism. It has a function of maintaining the open state and the closed state of the lid 40, respectively.

In addition, in order to operate the lighting device 32 by opening and closing the opening and closing lid 40, as shown in FIG. 2, when the opening and closing lid 40 is opened, the movable conductor 34a is pressed downward. In the state where the movable lamp 34 comes into contact with the fixed-side conductor 34b, the illumination lamp 33 is turned on and the opening / closing lid 40 is closed, that is, in the state shown in FIG. And the fixed-side conductor 34b
When the contact with the illumination lamp 33 is stopped, the power supply to the illumination lamp 33 is stopped, and the lamp 33 is turned off.

The mounting structure of the unit 20 for mounting the illuminated mirror unit 20 to the sun visor 10 is not an essential part of the present invention. The stop piece 36 is integrally formed, and is engaged in a mounting hole (not shown) provided at a corresponding portion of the sun visor 10, so that the illuminated mirror unit 20 can be one-touched into a concave portion on the front surface side of the sun visor 10. It is possible to attach with.

By the way, as described in the conventional example, if the conductor 34 is plastically deformed due to long-term use, the lighting device 32 is erroneously turned on even though the opening / closing lid 40 is closed. If the battery is left in this state, there are problems such as the battery being exhausted, wasteful consumption of electric power, and thermal deformation of peripheral components due to heat generation from the lighting device 32. The present invention solves such problems beforehand. For this purpose, the lid 40 is provided with an opening 42 for detecting an erroneous lighting of the lighting device 32.

That is, FIGS. 1 and 3 show a state in which the opening / closing lid 40 is closed. In this state, when the lighting lamp 33 of the lighting device 32 is turned on, the lighting lamp 33 passes through the opening 42. This causes the light from the vehicle to leak into the vehicle interior, and erroneous lighting of the lighting device 32 can be detected quickly.

The opening 42 may be set at any position of the opening / closing lid 40 corresponding to the lighting device 32. However, it is preferable to set the opening 42 at the terminal side of the opening / closing lid 40 in consideration of design.

Further, in order to install the means for detecting an erroneous lighting of the lighting device 32 in a good manner, as shown in FIGS.
A frame-shaped groove 43 is formed along the peripheral edge of the opening / closing lid 40, and an opening 4 is formed in the groove 43.
2 is preferable in terms of appearance, and the bottom of the groove 43 looks darker than the general surface of the opening / closing lid 40 due to shading, so that light leakage accompanying the erroneous lighting of the lighting device 32 through the opening 42 is improved. It can be detected reliably.

Although not shown, if a structure such as a cloth is attached to the surface of the lid 40 is adopted, an opening may be provided at a part of the edge of the decorated skin, or the periphery of the decorated skin may be provided. Various variations such as providing a groove along the groove and providing an opening in the groove are conceivable.

In the above-described embodiment, the illuminated mirror unit 20 is installed on the sun visor 10 for the vehicle on the side of the occupant in the auxiliary seat. For the rear occupant, the illuminated mirror unit is provided on the back side of the seat back. It is also possible to install 20.
