Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a vehicle interior lamp, and can be used for interior lighting of automobiles, etc., particularly for local lighting of rear seats.

[Background technology]

Traditionally, it has been used as night lighting inside cars, etc.
So-called ceiling lights are often used. However, since ceiling lights illuminate the entire interior of the vehicle,
It is difficult to use while driving so as not to obstruct the driver's front view. In addition, the light from ceiling lights generally has low illuminance and is not suitable for reading maps, documents, etc.
Against this background, high-intensity lamps are used in recent vehicles for local illumination.The lamps that can be used in the rear seats include spot lamps embedded inside the rear pillar of the vehicle or above the windows, or lamps with high illuminance for local illumination. A boom stand type lamp or the like is used, the base of which is fixed to the rear rear shelf or the like, and the tip of which extends toward the front of the rear seat.

[The problem that the idea aims to solve]

However, there are only a limited number of car models that come standard with embedded spot lamps for the rear seats.
In order to realize local lighting for the rear seats in any car model, it will inevitably be a retrofitted method. However, there have been problems in that it is difficult to obtain an appropriate installation space near the rear seat, and it is also difficult to mount it on the interior of a vehicle without damaging the exterior appearance.

Furthermore, normal rear seat lamps are designed to be operated from the rear seat, making it difficult to operate them from the front seat. For this reason, when it is desired to brighten the rear seat from the front seat, such as when handling luggage placed in the rear seat from the front seat, there is a problem that even if there is a lamp for the rear seat, the ceiling light has to be used.

An object of the present invention is to provide a vehicle room lamp that can be used for local illumination of the rear seat, can be operated from the front seat, is easy to install, and has an excellent appearance.

[Means to solve the problem]

According to the present invention, a vehicle interior lamp is provided with a mounting portion that is engaged with a stay portion of a headrest of a front seat in a vehicle interior, and a light emitting portion that illuminates a rear seat.

Here, as the attachment part, a pipe-shaped member through which a headrest stay or the like of the front seat can be inserted, or a hook hooked on the stay or the like may be used.

Further, as the light emitting part, a normal light source such as an incandescent bulb or a fluorescent tube may be used, and a lens or the like may be appropriately combined. Furthermore, if the light passing through the lens of the light emitting section can be adjusted from a diffused state to a focused state, it becomes possible to support the entire rear seat illumination or concentrated illumination for reading, etc.

[Effect]

In the present invention, the light emitting part is held backward by locking the mounting part to the stay part of the front seat headrest of the vehicle, and the light emitted from the light emitting part provides local illumination of the rear seat part. Therefore, there is no need to process the interior of the vehicle for installation.
The above objects can be achieved by easily installing the vehicle, making effective use of the gap between the seat back and the headrest of the front seat as an installation space, and improving the appearance of the interior of the vehicle.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings.

1 and 2 show a vehicle interior lamp 1 based on the present invention. As shown in FIGS. 3 and 4, this room lamp 1 is attached to a front seat 3 of a vehicle 2, and is latched to a pair of stays 5 on a headrest 4 of the front seat 3 so that the seat back 6, and projects light onto the front side of the rear seat 7 to provide local illumination.

In FIG. 1, a room lamp 1 of this embodiment is shown.
The light emitting unit 10 includes a light emitting unit 10 configured in a substantially rectangular parallelepiped case 11, and mounting units 20 connected by shafts 21 are provided on both sides of the light emitting unit 10.

The mounting portion 20 has a cylindrical cover 22 made of synthetic resin that is expandable and retractable in a bellows manner, and a mounting ring 23 is coaxially arranged inside the cover 22. A flexible rubber slit rubber 24 is attached to the inside of the mounting ring 23, and a small diameter hole 25 is provided in the center of the flexible rubber slit rubber 24.
is drilled, and the headrest 4 is inserted into this hole 25.
By press-fitting the stay 5, the stay 5 is held between the slip rubbers 24, and the mounting ring 23 is locked at an arbitrary position on the stay 5.

The shaft 21 is telescopically formed to be telescopic and rotatable, and has its base end connected to the case 11, and its distal end passed through the middle side of the cylindrical cover 22 to be introduced into the cover 22 and installed. It is fixed to the side surface of the ring 23.

As shown in FIG. 2, the light emitting unit 10 includes a window 12 opened on the front side of the case 11, and a light bulb 13 and a heat insulating reflector 14 are arranged inside. Light is irradiated to the outside through the window 12. At this time, by rotating the case 11 around the axis of the shaft 21, the direction of the irradiated light can be adjusted up and down. Further, a lens 15 is arranged inside the window 12.

The lens 15 is made of transparent plastic and has a cylindrical surface shape, and is rotatably supported at both ends so that it can be stopped at any angular position. The upper part of the lens 15 is a cut lens part 16 that scatters transmitted light,
The lower part is a condensing lens part 17 that condenses the transmitted light into a beam, and by rotation, the lens parts 16 and 17 located in the window 12 can be selected.

In addition, ON, DOOR,
Switch 1 that can be switched to 3 positions (OFF)
8 is arranged, and the battery wire and door lamp wire of the vehicle 2 are connected to the light bulb 13 via a switch 18 (not shown), and when the switch 18 is in the ON position, the light is on, and in the OFF position, the light is off, and in the DOOR position. It is configured so that it automatically turns on (just like a normal room lamp) when the door is opened or closed.

Next, the installation procedure and usage procedure in this example will be explained.

First, for installation, the headrest 4 of the front seat 3 is removed from the seat bag 6, and the mounting portions 20 on both sides are locked to the two rod-shaped stays 5. At this time, the shaft 21 is expanded and contracted to adjust the spacing between the attachment parts 20 on both sides, and each stay 5 is press-fitted into each attachment part 20 with the light emitting part 10 facing backward. In this state, by attaching the headrest 4 to the seat back 6 again, the vehicle room lamp 1 is held in the gap between the headrest 4 and the seat back 6 and attached to the front seat 3. Note that in the installed state, the cover 22
are expanded and contracted appropriately, and their upper and lower ends are moved to positions where they contact the headrest 4 and the seat back 6, respectively, to cover the stay 5.

On the other hand, in use, the light bulb 13 is turned on by operating the switch 18, and the rear-facing lens 15 is turned on.
The rear seat 7 is illuminated by light from the rear seat 7. On this occasion,
The illumination position is selected by adjusting the angle of the case 11 and changing the light projection direction up and down, and by rotating the lens 15, the cut lens part 1
By selecting any of the condenser lenses 6 to 17 or changing the ratio thereof, the illumination state is adjusted by scattering or concentrating the projected light.

According to this embodiment, the following effects can be obtained.

That is, by projecting light backward from the vehicle room lamp 1 disposed in the headrest 4 portion of the front seat 3, local illumination of the rear seat 7 can be performed.

In addition, the vehicle interior lamp 1 is attached to the head rest 4.
Since it is attached using the space between the seat back 6 and the seat back 6, the interior space of the vehicle 2 can be effectively utilized, and there are no protrusions or the like, resulting in an excellent appearance.

Furthermore, for installation, all you need to do is attach and detach the headrest 4 of the front seat 3 and press fit the stay 5 into the mounting part 20, and no other processing is required, so there is no risk of damaging the interior, and the work is easy. It's extremely easy to do.

In particular, the mounting portion 20 is secured by crimping with a slip rubber 24, making it easy to adjust the position, and by expanding and contracting the shaft 21, it can accommodate stays 5 of various spacings, expanding the range of use. .

Further, since the stay 5, the mounting ring 22, etc. are covered with the bellows-type cover 22, the visual sense of unity from the headrest 4 to the seat back 6 can be enhanced, and the appearance can be made even more excellent.

On the other hand, since the light emitting unit 10 is configured so that the direction of the projected light can be changed by rotating the case 11, the illumination position can be easily adjusted.

In addition, since the lens 15 can be switched between diffused light and concentrated beam, it is possible to arbitrarily select the dispersion and concentration state of the light during illumination, making it possible to freely illuminate the entire rear seat or for concentrated illumination for reading, etc. can correspond to

Furthermore, the vehicle room lamp 1 is placed in the headrest 4 of the front seat, and the switch 18 is
is placed on the top of the case 11, so the front seat 3
It can be operated freely from any of the seats 7 and 7.

It should be noted that the present invention is not limited to the above-mentioned embodiments, but also includes the following modifications.

In other words, the light emitting unit 10 is not limited to one that uses the light bulb 13, but may also use other light sources such as a fluorescent tube, a high-intensity LED, or an EL element, and the light emitting state can be switched in the same way as a normal room lamp. Similar ON,
Not limited to the 3 positions of DOOR and OFF, but also simple
It is also possible to switch only between ON and OFF.

Further, the format of the switch 18 is arbitrary;
For example, case 1 when switching only ON and OFF.
1 may be used, and the light may be turned off when the case 11 is facing straight down, and turned on when the case 11 is turned backward.

Furthermore, the installation position of the switch 18 is in the case 11.
The switch 18 can be operated not only from the top side but also from the front side, back side, bottom side, etc., and since the case 11 is rotatable, the switch 18 can be operated freely from any direction.

Further, the form of the lens 15 may be changed as appropriate.
The light scattering state is not limited to one in which the light scattering state changes with rotation. For example, the lower part may be colored so that the color of the transmitted light can be selected. Note that it is not essential to the present invention that the lens 15 be a switchable type, and may be a fixed type.

Furthermore, in order to adjust the lighting position, case 11
is rotatable around the axis of the shaft 21,
The mechanism for adjusting the illumination position may adopt other configurations as appropriate. For example, by providing an appropriate frame that is rotatable around an axis perpendicular to the case 11 and supporting this frame with the shaft 21, the projection optical axis can be adjusted in both the vertical and horizontal directions. The adjustment range of the irradiation position can be greatly expanded.

On the other hand, the cover 22 of the attachment part 20 may be changed or omitted as appropriate, or the attachment ring 23 for insertion and locking, the slip rubber 24, etc. may also have other configurations.

For example, as the mounting part 20, as shown in FIG. 5, a structure in which the case of the light emitting part 10 is enlarged, holes 26 are provided above and below the case, and the stay 5 is inserted and locked therein can also be used. Further, as shown in FIG. 6, a sandwich plate 27 made of resin or metal is provided on the back side of the light emitting part 10,
A configuration in which the stay 5 is sandwiched between the sandwich plates 27 and tightened with screws can also be used.

In addition, the mounting part 20 corresponds to the two stays 5,
In order to lock the light emitting part 10 between them, a pair are arranged on both sides, but when the headrest 4 has a single stay, a holder is provided which is inserted and locked to the stay, and the light emitting part 10 is supported by this holder. You can configure it like this.

Further, the attachment portion 20 is not limited to being locked to the stay 5 by insertion, but may be locked by a hook or clamp method.
