BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting mechanism for a register attached to an air conditioner in a vehicle.

[0002]

2. Description of the Related Art Conventionally, the amount of air blown out of a register of an air conditioner in a vehicle of this type is adjusted by adjusting an opening degree of a damper provided in a retainer 1 which is a passage thereof. In order to check the damper opening,
Japanese Unexamined Utility Model Publication No. 61-186050 discloses a retainer 1 shown in FIGS. 7 and 8.
A support shaft 2 is protruded from a predetermined position of the side portion 1a, and an operation lever 3 in which an operation arm 4 and an operation arm 5 are formed in a substantially rectangular shape is pivotally mounted on the support shaft 2; Actuating arm 4
A long hole 4a is penetrated at the tip end of the shaft. A pin 7a of a damper lever 7 is slidably fitted to and connected to the damper shaft 6 in the long hole 4a.

The arm 8 of the operation arm 5 is formed of a transparent resin, and the tip of the arm 8 is inserted into a guide groove of a grill 9 attached to the front of the retainer 1.
A light source 10 formed on the base side of the light source 10 is provided.
Is a light emitting diode 12 in a socket 11 connected to a power supply.
The light emitting display 13a and the light emitting unit 14 of the operation knob 13 attached to the tip of the arm 8 are illuminated by the light emission of the diode 12, and the opening of the damper is visually recognized.

In the former publication, the light source 10 is mounted on the operating lever 3 of the damper so as to rotate integrally therewith. However, the light source 10 is fixed to the retainer side separately from the operating lever of the damper. For example, Japanese Unexamined Utility Model Publication No. 2-121448 discloses a device provided with a light source. 9 and 10, a grill 16 is attached to the front surface of a retainer 15, and a support shaft 17 is protruded from a predetermined position of a side portion 15a of the retainer 15 as shown in FIGS. An operating body 18 is pivotally mounted on the support shaft 17. The operating body 18 is formed of a semicircular operating portion 19 and an operating arm 20 projecting rearward from the pivot portion. The operating arm 20 is attached to a damper shaft 22 of a damper 21 as shown in FIG. The damper lever 23 is connected to the long hole 23a via the pin 20a. A position display lens 24 made of, for example, a transparent resin or the like is fitted to a central portion of the operation section 19 of the operation body 18 thus formed.
9 is rotatably fitted in the guide groove 16 a of the grill 16.

A light source is provided on a side portion 15a of the retainer 15 in the frame of the operation portion 19 provided as described above, and a light source is provided. A grill 16 is provided in front of the light source. Bifurcated light guide 29 on the back of the open / close display lenses 26 and 27 attached to the upper and lower sides of the guide groove 16a, and the position display lens 2 of the operation unit 19
4 having an arc-shaped light emitting surface 30 for irradiating light 4
When the diode 8 is mounted and the diode 12 is turned on, the forked light guide portion 29 of the light guide lens 28 and the arc-shaped light emitting surface 3 are formed.
The opening / closing display lenses 26 and 27 and the position display lens 24 are provided so as to irradiate the light through the “0”.

[0006]

However, in the former case, since the light source 10 is provided so as to rotate integrally with the operation lever 3, the lead wire of the socket 11 may be bent and disconnected. In addition to the above, there is a problem that the lead wire cannot be fixed and thus is weak against vibration, a rotation angle of the operation arm 5 is restricted, and the operation load of the operation lever is affected. The latter is developed to solve the problem of the former, but the latter is a light guide lens 28.
The light of the light emitting diode 12 is guided by the arc-shaped light emitting surface 30 and the bifurcated light guide portion 29 to irradiate the position display lens 24 and the open / close display lenses 26 and 27, respectively. The light-emitting diode 12 has a straight-ahead property. Therefore, when a light source is placed at one location, the direction of the straight-ahead travel is mainly illuminated. However, there is a problem that the light is not sufficiently guided when moved to the side.

The present invention has been made in order to solve the above-mentioned conventional problems. The light emitting diode is arranged at a position different from the operating body of the damper, and the position indicating mark provided on the operating body is determined by the opening. It is an object of the present invention to provide an illumination mechanism of a vehicular register capable of always illuminating the same position display mark brightly even at a degree position and allowing the damper opening to be visually recognized.

[0008]

SUMMARY OF THE INVENTION In order to solve the above-mentioned technical problem, the present invention is to rotate a pivot of a retainer around a pivot of an operation body of an operation body connected to a damper attached to a retainer so as to be openable and closable. In addition to providing a bearing part as possible, a light incident convex part is formed on the bearing part, and between the light incident convex part and one or more light projecting surfaces formed on the arc-shaped mounting frame of the operation main body. A plurality of reflecting surfaces are provided to provide a supporting rod mainly composed of an insert lens for forming an optical path for irradiating the light projecting surface. A cylindrical body that is loosely fitted with the light convex portion is formed, and the cylindrical body is illuminated with the light-emitting diode, and is always opposed to the base inclined surface of the insert lens in a manner that the reflecting surface formed on the end surface is desired. Vehicle with a light source lens forming an optical path It resides in the lighting mechanism of the register.

[0009]

With the above arrangement, the reflecting surface of the light source lens of the light source unit and the base reflecting surface of the insert lens are provided opposite to each other regardless of the angle position of the operating body. The projection mark is irradiated.
