  However, according to these prior arts, the operation control devices for the plurality of light emitting means composed of LEDs or the like are required, and the control becomes complicated. In addition, each of the plurality of light emitting means is modified. Since it is necessary to attach to the side portion of the tire that is inevitably attached by adhesion or the like, there is a problem that the number of man-hours required for installation increases, but the durability of the installation cannot be denied.

The present invention solves such problems of the prior art by forming a mark on the side of the tire in advance. The object of the present invention is to provide an operation control device for the light emitting means and a complicated one. with Do eliminating the need for operation control, sufficiently reduces the mounting effort of light emitting means, also, provides a light emitting means, the target AkiraTeru AkiraSo location of the tire sides feared effectively remove such unintended peeling fall There is to do .

Here, the “rim-equipped tire” means the tire size according to the YEAR BOOK such as TRA, ETRTO, JATMA, etc., which is an industrial standard effective in the region where the tire is produced or used. The tire is mounted on a rim that is defined accordingly, and the tire is used in a state of being filled with air pressure that is defined in accordance with the required load capacity.
The air pressure referred to here may be an inert gas such as nitrogen gas or other filling pressure.

Further, the mark illumination device for the tire side portion according to the present invention is similar to the above-described character, figure, symbol, or an appropriate combination thereof provided on the side outer surface of the “rim-assembled tire”. And a light emitting means for irradiating the light toward the mark on the valve cap of the tire, and applying power to the light emitting means inside the tire. Ri Na by disposing the generator means for supplying,
The power generation means is a piezoelectric power generation means that generates power based on deformation of the tire and intermittently supplies power to the light emission means,
The light emitting means and the power generation means are arranged on opposite sides in the diametrical direction with the central axis of the tire therebetween .
By using the piezoelectric power generation means, the power generation means can be reduced in size.

In addition, the piezoelectric power generation means is preferably attached to the inner surface of the tread portion or the sidewall portion, which has a large amount of deformation during load rolling of the tire.

  In the above apparatus, the light emitting means is preferably an LED.

Further, in the tire side mark illuminating device of the present invention, the mark on the outer side surface of the tire covered with the coating of the retroreflective coating is illuminated with a single light emitting means attached to the bulb cap. In the same way as described above for the lighting method, the illuminated mark can be recognized sufficiently clearly by the viewer at night, etc., and the light emitting means can be easily attached to the bulb cap. In addition, it is possible to sufficiently eliminate the possibility of dropping of the light emitting means.
In addition, the lighting device can be easily and easily applied to existing tires.

  In addition, in this apparatus, the wiring between the power generation means inside the tire and the light emission means on the valve cap can be made extremely simple, for example, through an air valve.

In such devices, the light emitting means, and power generation on the basis of the deformation of the tire, due to a piezoelectric luminous means for supplying intermittently electric power to the light emitting means, in comparison with the power generation means such as an electromagnetic induction type power generation unit Can be reduced in weight and size.

Further, in the case such, the mutual light-emitting means and the piezoelectric power generation means, for which is arranged diametrically opposite at a central axis of the tire, is emitted along a generator and timing by the power generation means The light emitting means can illuminate the mark in an appropriate posture for visual recognition. By synchronizing the light emission timing of the light emitting means with the timing when the mark reaches an appropriate posture for visual recognition, the strobe effect described above can be achieved. Based on this, the still visibility of the mark can be further enhanced.

  Furthermore, when the light emitting means of this lighting device is an LED, the power consumption is much reduced and the life is extended compared to the case where the light emitting means is an incandescent bulb, a fluorescent lamp, or the like. It is possible to reduce the amount of heat generated and the size of the light emitting means, and remove the restriction on the mounting position of the light emitting means, simplify the mounting of the light emitting means itself, and sufficiently increase the mounting strength. be able to.

It is a partial side view which illustrates the mark provided on the side part outer surface of the tire of a rim | limb assembly | attachment attitude | position with a rim | limb. It is an approximate line longitudinal section showing an embodiment of an illuminating device concerning this invention. It is a side view which shows the operation state of the apparatus shown in FIG.

The present invention will be described below with reference to the drawings.
In FIG. 1, reference numeral 1 denotes a tire, 2 denotes a rim to which the tire 1 is assembled, and 3 denotes a company name, a product name, etc. provided on the outer side surface of the tire in a rim assembled posture. The required mark is shown.

  Here, the mark 3, which can be appropriately selected from characters, figures, symbols and the like, and can be a logo type, a logo mark, a character mark, etc., can be a bead type, a prism type, or the like. A retroreflective paint, for example, a paint blended with glass beads having a refractive index of 1.4 to 2.0 is applied to form a coating film (not shown), as shown in FIG. A single light emitting means 5, preferably an LED, is attached to the tire valve cap 4 for irradiating a light beam directed toward the mark 3, and an electromagnetic induction type, piezoelectric type, electrostatic type is installed inside the tire 1. For example, the power generation means 6 that generates power constantly or intermittently as the tire rotates is provided.

Here, the power generation means 6 can be electrically connected to the light emitting means 5 via a lead wire routed in the inner cavity of the tire 1 and can be electrically connected via a metal rim 2. The light emitting means 5 can illuminate the mark 3 by emitting light by the supplied power while the power generating means 6 is generating power.
When the light emitting means 5 is an LED, the irradiation distance, the irradiation angle, the irradiation range, and the like can be adjusted by selecting the directivity angle and the luminous intensity of the LED as described above.
By the way, when using a lightweight and small piezoelectric power generating means 6 as the power generating means 6, the piezoelectric power generating means is applied to the inner surface of the tread portion or the sidewall portion where deformation during load rolling of the tire is particularly large. By disposing, the amount of power generated by the power generation means 6 can be increased, the light emission illuminance of the light emission means 6 can be increased, and clearer illumination of the mark on the outer side surface of the tire can be realized. .

  Here, when the light emitting means 5 and the power generation means 6 are disposed on the opposite side in the diametrical direction with the central axis CL of the tire 1 as shown in FIG. Each time the power generating means 6 that can be entered enters the contact area and power is supplied from the power generating means 6 to the light emitting means 5, the light emitting means 5 is caused to emit light so that the mark 3 is illuminated radially outward. Therefore, as shown in FIG. 3 in the lighting state with increased brightness, the arrangement of the mark 3 is set to an appropriate posture for visual recognition, and under the action of the coating film of the retroreflective paint. The reading of the mark 3 by the observer from the side of the tire can be made sufficiently easy. This means that the light emission timing of the light emission means 5, more directly, to the contact area of the power generation means 6. The approach timing and the mark 3 are appropriate for visual recognition as illustrated in FIG. Is particularly remarkable when in synchronization and timing, in this case, under the stroboscopic effect, the mark 3, it can be visually recognized by the as if it were stationary.

  Here, in order to set the light emitting means 5 and the power generating means 6 to a relative position as shown in FIG. 2, the light emitting means 5 that can be an LED is firmly attached to the valve cap 4. At the same time, the mark 3 is positioned on the outer side in the radial direction of the light emitting means 5 in a state where the power generation means 6 is disposed inside the tire at a position 180 degrees apart from the mark 3 on the tire side portion. Next, the tire 1 is assembled to the rim 2.

  According to the illuminating device configured as described above, the mark 3 provided on the outer surface of the side portion of the tire 1 in the rim-assembled posture and coated with a retroreflective coating to prevent irregular reflection of light. The single light emitting means 5 that emits light by the power supplied from the power generating means 6 disposed inside the tire 1 can illuminate outward in the radial direction, so that the visibility of the mark 3 can be improved particularly at night. Can be effectively increased.

  In this case, when the mark 3 is illuminated by a single light emitting means 5 attached to the bulb cap 4, the light emitting means 5 can be mounted more easily than in the prior art in which a large number of light emitting means are provided. In addition, the mounting strength can be sufficiently increased to effectively eliminate the possibility of unexpected dropouts, etc., and each operation control device for a large number of light emitting means is unnecessary, and the operation control itself can be performed. It can be made unnecessary.

  Further, here, when the mark 3 is illuminated by the light emitting means 5 that is disposed inside the tire 1 and emits light by intermittently supplied electric power from the piezoelectric power generating means that generates electric power based on deformation of the tire 1. The power generation means itself can be made light and small, and there is no special control to make the mark 3 still visible by the strobe effect under the selection of the rotation speed of the tire 1 or the like. It can be made easy.
