The three-way support rod portion 2 and a circular wheel body 3 fixed to the tip of the three-way support rod portion 2 are configured.
[0016]
As shown in detail in FIGS. 2 (a) and 2 (b), the wheel body 3 includes an opaque resin member 4 having an elliptical cross section and a circular upper half driver side cut out, and the opaque body. It is comprised from the light transmissive member 5 which is fixed to the notch part of the resin member 4, and has a shape which supplements a notch part. On the surface of the lower half of the opaque resin member 4 on the driver side, a design such as wood grain or silver tone (shown in fine dot display in FIGS. 1A and 1B) is applied by printing or the like. Yes. The light transmissive member 5 is composed of two layers of a polycarbonate resin transparent resin layer 5a disposed on the outer surface side and a polycarbonate material printing transparent resin layer 5b disposed on the inner surface side. A design portion 6 is provided on the inner surface of 5b.
[0017]
The design unit 6 includes a light shielding region S1 that shields light from the display devices 10a to 10c and a light transmission region S2 that transmits light from the display devices 10a to 10c, and these are alternately arranged at fine vertical intervals. It is arranged. A printing layer 7 is provided in the light shielding area S1, and the printing layer 7 is designed in a wood grain or silver tone or the like in order from the driver side (details shown in FIGS. 1A and 1B). The design print layer 7a is provided with a white print layer 7b that reflects light, and a black print layer 7c that absorbs and blocks light. Is bonded to the transparent resin layer 5b for printing. The printing layer 7 is provided by printing directly on the printing transparent resin layer 5b or by sticking a printed sheet to the printing resin layer 5b. The design of the design print layer 7a is generally the same as that of the outer surface of the wheel body 3 described above. Nothing is arranged in the light transmission region S2, and light is transmitted through the air layer.
[0018]
The three display devices 10a to 10c are each configured by a liquid crystal display device, for example, and are arranged at the upper center position of the wheel body 3 of the steering wheel 1 located at the neutral position. Therefore, the display devices 10 a to 10 c are arranged side by side at the inner position of the light transmissive member 5. The left display device 10a is an engine warning, the central display device 10b is a battery warning, and the right display device 10c is a hydraulic warning. The warnings are displayed on the display devices 10a to 10c during each warning. Irradiate.
[0019]
The pair of side light sources 11 is built in the wheel body 3 at a position slightly below the both ends of the light transmissive member 5, and toward the upper side in the wheel body 3 from the both ends of the light transmissive member 5. Irradiate with light. Each side light source 11 is composed of, for example, red, green, and blue LEDs (light emitting elements), and can emit light of a desired color.
[0020]
Further, the inner or outer surface of the light-transmitting member 5 and the surfaces of the upper end portion and the lower end portion B (region surrounded by a broken line in FIG. 2B) that are not display areas when viewed from the driver side are: It is formed on a fine uneven surface (not shown).
[0021]
In the above configuration, when none of the three display devices 10a to 10c is driven to be turned on and is not displayed with a warning, external light is partially reflected and partially absorbed by the design print layer 7a and the design print layer 7a. The light transmitted through the light is reflected by the white print layer 7b, so that the design of the design print layer 7a appears to stand out. In other words, as shown in FIG. 1 (a), the entire wheel body 3 appears to the driver as if it was designed with wood grain or silver.
[0022]
When one of the three display devices 10a to 10c is lit and driven and displayed with a warning, the light that has entered the light shielding area S1 out of the irradiation light from the display devices 10a to 10c is black printed layer. Since it is shielded by 7c and does not enter the design print layer 7a, the design of the design print layer 7a cannot be seen. Since the light that has entered the light transmission region S2 is transmitted to the surface side of the light transmissive member 5, the warning display images of the display devices 10a to 10c can be seen. In other words, as shown in FIG. 1B, the driver can see a warning display without looking at the upper half of the wheel body 3 which is designed with wood grain or silver.
[0023]
As described above, the warning display device A uses the steering wheel 1 that has not been used as a warning display area until now, and displays a warning on the steering wheel 1 that has the closest eye point to the driver. In addition, the driver can easily recognize the warning display. In addition, the warning display is not frequently lit, and the steering wheel 1 is not normally seen as designed such as wood or silver, so that the aesthetic appearance is not impaired. Further, in the conventional example, there is a possibility that the warning display is difficult to see because it is hidden behind the steering wheel 1, but in the present invention, such a situation can be avoided because the warning display is made on the steering wheel 1 itself.
[0024]
When the side light source 11 is turned on at night when no warning is displayed, the irradiated light diffuses on the uneven surface (not shown) of the light transmissive member 5 and the upper and lower ends of the light transmissive member 5 from which diffused light is emitted. Since the part B (the region surrounded by the alternate long and short dash line in FIG. 4) appears to shine, it is possible to produce an effect as illumination.
[0025]
In this embodiment, since the display devices 10a to 10c are arranged at the upper center position of the wheel body 3 of the steering wheel 1 located at the neutral position, the warning display is performed at a position where the driver can see the steering wheel 1 most easily. Therefore, the driver can most easily recognize the warning display.
[0026]
In this embodiment, since the design portion 6 is provided on the inner surface of the light transmissive member 5, the design portion 6 is not worn or peeled off even if the driver holds the steering wheel 1 for many years.
[0027]
FIG. 5 is an enlarged cross-sectional view in the vicinity of the design portion showing a modification of the embodiment. As shown in FIG. 5, in this modification, the design portion 6 is provided on the surface side of the light transmissive member 5. Contrary to the above-described embodiment, the light transmissive member 5 is composed of two layers of a polycarbonate resin transparent resin layer 5a disposed on the inner surface side and a polycarbonate material printing transparent resin layer 5b disposed on the outer surface side. And the design part 6 is provided in the outer surface of the transparent resin layer 5b for printing. The design unit 6 includes a light shielding region S1 that shields light from a display device (not shown) and a light transmission region S2 that transmits light from the display device (not shown). They are arranged alternately at intervals. A printing layer 7 is provided in the light shielding area S1, and this printing layer 7 reflects light in order from the driver side, with a design printing layer 7a having a design such as woodgrain or silver tone. The white print layer 7b is composed of a white print layer 7c that absorbs and shields light, and the black print layer 7c is bonded to the transparent resin layer 5b for printing.
[0028]
Since the other configuration is the same as that of the above-described embodiment, the description is omitted to avoid redundant description.
[0029]
Also in this modified example, the limited space in the vehicle can be used effectively, and the driver can easily recognize the warning display as in the above embodiment.
[0030]
In the embodiment and the modified example, the light shielding regions S1 and the light transmitting regions S2 of the design unit 6 are alternately arranged at fine vertical intervals, but may be alternately arranged at fine horizontal intervals.
