Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an interior illumination lamp, and more particularly to an interior illumination lamp that is detachably attached to and rotatably held by a flag that is inserted into an outlet for a cigarette lighter in the vehicle. .

[Conventional technology]

2. Description of the Related Art Conventionally, as an in-vehicle illumination lamp, there is one that can change the irradiation angle and direction of a lamp, for example.

[Problems to be solved by the device]

However, in the above-mentioned conventional one, the irradiation angle and direction can be changed, but there is a problem that irradiation cannot be performed at hand because only the lamp portion cannot be easily separated.

The present invention has been made in view of the above circumstances, and it is possible to easily adjust the angle and direction of tools such as a lamp easily, and even if the lamp part is rotated, friction or abnormal noise does not occur. (EN) Provided is an in-vehicle illuminating lamp which has a feeling, and in which only the operating portion can be easily separated, and which is mechanically simple and can be manufactured at a low cost.

[Means for solving the problem]

The in-vehicle illumination lamp of the present invention has a plug fixed to an outlet for a cigarette lighter in a vehicle, a holder main body connected to an outer end of the plug, and an end surface of the holder main body having a common axis. Further, a part of the outer circumference thereof is translucent and comprises an al lamp portion, and magnets are attached to the joint end surfaces of the holder body and the lamp portion, respectively, and the magnet has a plurality of N poles and S poles in the circumferential direction. The holder body and the lamp portion are detachably and rotatably joined to each other by the attraction force between the different poles of the magnet.

〔Example〕

 An embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 1 and 2, reference numeral 1 is a holder main body formed in a bottomed cylindrical shape, and a fitting recess 2 is formed in the holder main body 1.

Further, a ring-shaped magnet 4a is attached to the inner bottom surface 3 of the fitting recess 2, and the magnet 4a is also attached.
A positioning protrusion 3a that fits with the central part of the is formed.

The end surface of the magnet 4a is formed as a so-called multi-pole magnet in which a plurality of N poles and S poles are alternately arranged in the circumferential direction as shown in FIG. By the way, in this embodiment, it is divided into 24 sections, and the N and S poles are alternately magnetized at angular intervals of 30 degrees.

Further, as shown in FIG. 4, a connecting piece 5 is formed on the outer bottom surface of the holder main body 1, and a connecting piece 6 having a positioning joint 6a is connected to the connecting piece 5. A plug 7 inserted and held in a lighter outlet (not shown) is attached via the joint 6.

Further, as shown in FIGS. 1 to 3, a cord 8 having a sufficient length to be connected to a power source is attached to the plug 7.

An actuating portion 9 is loosely fitted in the fitting recess 2 of the holder body 1 with a common axis. In this embodiment, the actuating portion 9 and the tubular lamp portion 10 are integrated. ing.

One side of the operating portion 9 is a small diameter portion that is loosely fitted in the fitting recess 2 of the holder body 1, and a ring-shaped magnet 4b is embedded in the tip surface of the small diameter portion of the operating portion 9. A recess 9a into which the positioning protrusion 3a is fitted is formed in the central portion.

The magnetized surface of the magnet 4b is a multi-pole magnet having the same structure as the magnet 4a attached to the holder body 1.

On the other side of the operating portion 9, a cylindrical lamp portion 10 is integrally formed. The lamp portion 10 includes a non-translucent semi-cylindrical shade 11, a light bulb 13 connected to a terminal 12 in the shade 11, and a translucent semi-cylindrical cover attached to the opposite side of the shade 11 with a screw 14. It consists of 16 and.

The plug 7 is attached to the base opaque portion 15 of the cover 16.
The end of the cord 8 attached to the terminal is attached, and the end of the cord 8 is connected to the terminal 12.

A power switch 17 is provided at the terminal 12.

In the vehicle interior lighting according to the present invention, magnets 4a and 4b, which are magnetized by alternately arranging a plurality of N poles and S poles in the circumferential direction, are attached to the joint end surfaces of the holder body 1 and the operating portion 9 with each other. Therefore, the holder body 1 and the operating part 9 are magnets 4a, 4
When the opposite poles of b face each other, they are joined by the attraction force, and when the same poles face each other, they are separated by the repulsive force. Therefore, the rotation angle of the lamp portion 10 can be selected at regular intervals according to the number of N poles and S poles (in this embodiment, the angle can be changed at intervals of 30 degrees). Further, by rotating the actuating portion 9 relative to the holder body 1, the translucent portion of the lamp portion 10 can be oriented in any direction.

Further, since the repulsive force between the same poles is applied and the adsorbing force between the different poles immediately adsorbs each other only by slightly rotating the operating portion 9, it can be easily rotated with a slight force.

Further, in this case, the repulsive forces of the same poles cause the two to be instantly separated from each other, so that friction at the time of rotation and abnormal noise or magnetic particles due to the friction are not generated.

In addition, not only there is no friction between the magnets 4a and 4b during rotation, but also a repulsive force and an attractive force are alternately applied, so that a comfortable click feeling can be obtained.

Also, since the magnets 4a and 4b are joined by the attraction action, the holder main body 1 and the operating portion 9 can be easily separated, and the lamp portion 10 can be brought near by hand and illuminated.

Further, when the operating portion 9 is slightly rotated at the time of separation, the same polarities face each other and a repulsive force is generated, so that the holder body 1 and the operating portion 9 (ramp portion 10) are smoothly separated without any resistance. Therefore, the force required for separation is not required at all as compared with the case where the normal N-pole magnet and the S-pole magnet are joined.

As described above, in the interior illumination lamp of the present invention, it is extremely easy and smooth to change the rotation angle of the lamp part 10 or to separate only the lamp part 10, so especially in the case of long-distance driving at night or night rally etc. It demonstrates its strengths.

It should be noted that the fitting recess 2 may be formed in the operating portion 9 and the holder body 1 may be formed with a small diameter portion.

The magnets 4a and 4b may be of any type such as ferrite magnets, rare earth magnets, and plastic magnets.

[Effect of device]

As described above, according to the vehicle interior lighting of the present invention, since the lamp portion is held by the outlet through the plug inserted into the cigarette lighter outlet, the holding and the power connection can be made with one touch, which is extremely convenient. , Also, the lamp part is connected to the plug with a plurality of N
Since the poles and S poles are connected so as to be rotatable and detachable via magnets arranged alternately, the angle of rotation can be arbitrarily selected in a plurality of stages according to the number of N poles and S poles, and the operating part can be rotated slightly. Since they are instantly separated by the repulsive force between the same poles only by moving them, friction at the time of rotation and abnormal noise and magnetic particles due to them are not generated.

Further, not only there is no friction between the two magnets at the time of rotation, but also a repulsive force and an attractive force are alternately applied, so that a comfortable click feeling can be obtained.

Also, when the operating part is slightly rotated at the time of separation, the same poles face each other and a repulsive force is generated, so that the holder body and the operating part can be smoothly separated without any resistance. No force is required at the time of separation as compared with the case where the magnet and the S pole magnet are joined.
