Description

[Detailed Description of the Invention] <<Industrial Application Field>> This invention relates to an interior light for automobiles such as passenger cars, and particularly to an automobile interior light for spot lighting.

<<Prior Art>> Conventionally, various spot light lighting devices have been put into practical use as interior lights for automobiles such as passenger cars.
These generally project the light beam from a light source bulb installed inside the lamp housing onto a specific location inside the vehicle through a condensing lens, making it easier to view maps, books, etc. inside the vehicle. It is structured as follows.

Moreover, various kinds of indoor lamps for spot illumination have been developed in which the location of the light emitted can be changed as required.

《Problem to be solved by the invention》 In the conventional general automotive spot lighting equipment as described above, the light emitting point is fixed at a specific place, so there are multiple places in the vehicle interior (for example, the driver's seat). If a spot light is required for a passenger seat, an auxiliary seat, a rear seat, etc.), it is inconvenient to equip multiple spot lights.

In addition, as mentioned above, lighting equipment in which the light projection location is variable has been developed. For example, Utility Model Application No. 59-123901, Utility Model Application No. 61-177932, and Utility Model Application No. 61-177932
There are those disclosed in Publication No. 177933. However, these variable light emitting point lighting devices have a complicated structure, are prone to failure, and are not smooth to operate, making them inconvenient to operate while driving or riding in the vehicle. Furthermore, since a ball joint type structure was used for the lamp housing, manufacturing required a great deal of effort and precision, resulting in high costs.

In view of the problems of conventional products as mentioned above, this idea was designed to cover the necessary areas of a large number of spot lights in the vehicle interior with a single light fixture without having to install multiple spot lights, and the structure is simple and smooth. It is an object of the present invention to provide an interior lamp for a spotlight that can be operated.

<Means for Solving the Problems> In order to achieve the above object, the automotive interior light of this invention includes a housing in which a light source bulb is installed, and a housing that is slidably and rotatably fitted around the opening side of the housing. and a circular tray-shaped cover rotatably attached to the periphery of the opening side of the housing via a plurality of sliders, and a circular tray-shaped cover is provided at an eccentric position on the bottom surface of the cover. A lens for projecting light from the light source bulb in an oblique direction is attached, and the slider is attached to the peripheral surface of the opening side of the housing so as to be slidable in the radial direction, and is always urged outward in the radial direction by a spring. , whose tip part slidably and rotatably holds a fixing ring fixed to the inner circumferential edge of the cover, and the inner surface of the switch ring is provided with a fixing ring fixed to the housing by rotation of the switch ring. The device is characterized in that it is equipped with a switch ball that contacts and detaches from the terminal to turn on and off the power source of the light source bulb.

<Operation> In the automobile interior light of this invention constructed as described above, by manually rotating the switch ring, the switch ball contacts and separates from the terminal to turn on and off the light source bulb. blinks. Further, by manually rotating the cover, the condensing lens eccentrically mounted on the cover is displaced, and the spot where the spotlight is projected changes. The aforementioned power on/off operation is carried out smoothly by the rolling of the switch ball, and the lens displacement operation is also carried out smoothly and reliably by the action of the slider pressed outward by a spring. will be carried out.

<<Example>> Hereinafter, the structure of this invention will be explained in more detail based on the example shown in the drawings.

In the figure, reference numeral 1 denotes a housing formed into a circular conical shape with an open end (lower side in FIG. 1) and a peripheral edge 1a that opens like a brim on the opening side, and a light source bulb 2 is installed inside the center of the housing. There is. Housing 1
As shown in the figure, the peripheral edge 1a has an inverted U-shaped cross section, into which an annular switch ring 3 is fitted. This switch ring 3 can slide and rotate with respect to the housing 1, and has a notch 3a for knurling on its circumferential surface as shown in FIG. 2, making it convenient to rotate by hand. It's like this.

The switch ring 3 on the opening side of the housing 1
A tray-shaped cover 4 is provided further outward (lower side in FIG. 1). A ring-shaped fixing ring 5 is fixed to the stepped part on the inner surface of the circumferential edge of the cover 4 by welding or adhesive.
The fixing ring 5 is held by sliders 6 (three sliders attached every other time).

FIG. 3 is a cross-sectional view of the middle part of FIG. 1 showing the mounting portion of this slider, and FIG. 4 is a perspective view showing the external shape of the slider. slider 6
is fitted in a dovetail groove provided on the surface (lower surface in the figure) of the housing peripheral portion 1a so as to be able to slide in the radial direction of the housing 1. A rib 1b is formed protruding from the inner surface of the side wall of the housing 1, and this rib 1b has a spring property and serves as a pressing spring that always urges the slider 6 outward in the direction of radiant heat. . The slider 6 is pressed outward by this spring (rib 1b), and holds the fixing ring 5 on the inner peripheral surface of the cover 4 with its hook-shaped tip 6a. It is held below the switch ring 3. The cover 4 can slide and rotate while being held by the slider 6 in this way,
The switch ring 3 is also attached to the circumferential surface of this cover 4.
Similarly, a notch 4a is provided for convenient rotation by hand. In this embodiment, the slider 6 is supported by the springy rib 1b formed in a part of the housing 1 as described above.
Although the slider is pressed outward, a separate spring for pressing the slider may be provided.

A condenser lens 7 is fitted into the bottom surface of the cover 4 at an eccentric position. As seen in FIG. 1, the lens attachment part of this cover 4 has an opening so that the condenser lens 7 can be attached diagonally, and the peripheral edge of the condenser lens 7 is thermally caulked to the opening. and fix it. The light from the light source bulb 2 is transmitted through a condenser lens 7 and projected as a spotlight, as shown by the chain line in FIG. By manually rotating the cover 4, the condenser lens 7
By changing the position of the spotlight, the spotlight can be directed to any desired location. The cover 4 is usually made of an opaque material such as synthetic resin, but it may also be made of a semi-transparent material, in which case it can serve both as a spotlight and a general illumination inside the vehicle.
