  By the way, in the above-described prior art, when the vehicle travels, the pattern and characters attached to the side surface of the rotating tire also rotate together with the tire. Therefore, depending on the travel speed of the vehicle, the pattern or character on the tire side surface Etc. could not be recognized clearly and visually from the outside of the vehicle.

  Thus, in the above-described conventional technology, since the display on the tire side surface cannot be recognized from the outside of the vehicle when the vehicle is traveling, for example, from the display on the tire side surface of each vehicle traveling on the racing course, The traveling speed of the vehicle could not be grasped visually, and the display on the side of the tire could not be recognized as a moving image when the vehicle was traveling.

  The present invention solves such a problem of the prior art by intermittent irradiation of the tire side surface by a light source installed outside the vehicle, and its main purpose is to The object is to provide a method for irradiating the tire side surface by visualizing the tire side surface from the outside so that the running speed of the vehicle can be grasped. An object is to provide a method for irradiating a tire side surface that can be recognized as a moving image.

  The method of irradiating the tire side surface according to the present invention provides a display applied to the side surface of the tire by irradiating light on the side surface of the tire that is mounted on the vehicle and rotated when the vehicle is running, for example, a company name, a brand name, or the like. A method of visually recognizing marks, decorative patterns, figures, etc., and dividing the tire side into multiple rows of annular regions adjacent inside and outside in the radial direction of the tire and displaying the same in the annular region Are arranged at intervals in the circumferential direction, and the circumferential arrangement pattern of the plurality of displays is different from each other in each annular region, and when the tire mounted on the traveling vehicle is rotated The tire side surface is irradiated intermittently at a constant cycle by a light source installed outside the vehicle.

  Further, according to another tire side surface irradiation method of the present invention, when the vehicle travels, light is applied to the side surface of the tire that is mounted on the vehicle and driven to rotate, and the display on the side surface of the tire is visually recognized. In the method, a plurality of indications are provided on a tire side surface at intervals in the circumferential direction, and the shape of the plurality of indications changes toward one side in the circumferential direction in at least a part of the circumferential direction. When the tire mounted on the traveling vehicle is rotated, the side surface of the tire is intermittently irradiated in synchronization with the rotation of the tire by a light source installed outside the vehicle.

  According to the tire side surface irradiation method of the present invention, a plurality of the same indications are provided on each of the plurality of rows of annular regions on the tire side surface at intervals in the circumferential direction. The circumferential display patterns of the plurality of displays are different from each other. For example, when rotating a tire of a vehicle that travels in a dark environment such as at night, a tire is formed by a light source installed outside the vehicle. By irradiating the side surface intermittently with a certain period, depending on the running speed of the vehicle, only a specific annular region on the tire side surface, and a plurality of displays provided in the annular region are stationary at the same position in the circumferential direction If the running speed changes, the display will appear to be stationary only in the other annular area. Position or at the side, for example, were different in each other of the annular region, the display color, based on the size or the like, it is possible to grasp the traveling speed of the vehicle visually.

  Further, according to another tire side surface irradiation method of the present invention, a plurality of indications provided at intervals in the circumferential direction are arranged on the tire side surface while changing the form toward one side in the circumferential direction. For example, when rotating a tire of a vehicle traveling in a dark environment, the tire side surface is intermittently irradiated with a light source installed outside the vehicle in synchronization with the rotation of the tire. Each of the multiple displays that change their form as they go to one side of the direction appears to move at the same position in the circumferential direction, so the display on the side of the tire looks like a video when the vehicle is running Can be recognized.

  And by any of the above two irradiation methods, the display on the side of the tire can be visually recognized when the vehicle is running, so the display on the side of the tire can be displayed as a company name, brand name, By making a decorative pattern, figure, etc., it is possible to improve the advertising function by the tire, the decorative beauty of the tire, and the like.

  In the above irradiation method, since the light source is installed outside the vehicle, for example, on the ground stand of the circuit, an increase in the weight of the vehicle when the light source is attached to the vehicle side can be prevented. Moreover, it is possible to simultaneously irradiate the tire side surfaces of a plurality of vehicles traveling on a course at the time of a race, for example, by a light source installed outside the vehicle.

It is a side view of the tire which can be used for one irradiation method of this invention. It is a figure which shows how the tire side surface looks when the tire of FIG. 1 rotates at a predetermined speed. It is a figure which shows how the tire side surface looks when the tire of FIG. 1 rotates at a predetermined speed. FIG. 2 is a course diagram showing a circuit for running a vehicle equipped with the tire of FIG. 1. It is a side view of the tire which can be used for the other irradiation method of this invention. It is a figure which shows the aspect of the change recognized visually by the display given to the side surface of the tire of FIG.

Embodiments of the present invention will be described below with reference to the drawings.
In the place shown in FIG. 1, in the figure, 1 is a tire that can be used in one irradiation method of the present invention, and 2 is a mark, pattern, or other display consisting of characters, drawings, symbols, etc. The side surfaces of the tire 1 are shown.

1, the tire side surface 2 is divided into three rows of annular regions 3a, 3b, and 3c that are adjacent to the inside and outside of the tire in the radial direction of the tire and are indicated by phantom lines in the drawing, and each of the annular regions 3a, 3b, and 3c. For example, a plurality of marks 4 formed by arranging a plurality of characters are provided at equal intervals in the tire circumferential direction.
Here, in order to make the arrangement pattern of the mark 4 different between the annular regions 3a, 3b, 3c, for example, as shown in FIG. 1, in the inner annular region 3a located at the innermost side in the tire radial direction, Is provided with six marks 4 arranged side by side in the circumferential direction, and in the central annular area 3b adjacent to the outer side in the radial direction of the inner annular area 3a, eight pieces having a character size smaller than the mark 4 of the inner annular area 3a. Further, ten marks 4 having a smaller character size can be provided in the outer annular region 3c located on the outermost side in the tire radial direction.
In addition, such a mark can be provided on the tire side surface 2 by, for example, solid coating by printing, coloring rubber, coating to be applied with paint, or a sticker attached.

  In carrying out one irradiation method of the present invention using the tire 1 shown in FIG. 1, for example, the tire 1 attached to the rim is mounted on a vehicle (not shown) and the vehicle is driven at night. When the vehicle travels, the side surface 2 of the rotating tire 1 is intermittently irradiated at regular intervals by an illumination device (not shown) that is installed outside the vehicle.

At this time, when the side surface 2 of the tire 1 is viewed from the outside of the vehicle, each mark 4 provided in the inner annular region 3a of the tire side surface 2 that is irradiated at a certain cycle is obtained under a specific traveling speed of the vehicle. As shown in FIG. 2 (a), since it seems to be stationary without changing the arrangement position in the circumferential direction, it is possible to clearly recognize the mark 4 of the inner annular region 3a, while other annular regions The mark 4 provided on 3b and 3c cannot be clearly recognized because the arrangement pattern is different from that of the inner annular region 3a.
When the vehicle accelerates or decelerates and reaches another specific traveling speed, as shown in FIGS. 2B and 3A, the annular region where the mark 4 can be clearly recognized is the central annular region 3b. Or the outer annular area 3c, and depending on the traveling speed of the vehicle, as shown in FIG. 3B, the marks 4 of all the annular areas 3a, 3b, 3c may be clearly recognized. is there.

  Therefore, according to this method, the annular pattern 3a, 3b, 3c on the tire side surface 2 has a different arrangement pattern of the marks 4 from each other, so that the cycle for irradiating the tire side surface 2 is set in advance. Thus, when the tire side surface 2 is viewed from the outside of the vehicle, the traveling speed of the vehicle can be recognized from the position of the tire side surface 2 where an annular region that can be visually recognized exists.

The irradiation method described above will be described in more detail. For example, when it is assumed that a vehicle equipped with a tire 1 having an outer diameter of 955 mm is traveling at a speed of 144 km / h, the outer peripheral length of the tire 1 is 3 m. Since the traveling speed is 40 m / sec, the tire 1 rotates 13.3 per second.
When the side surface 2 of the tire 1 that rotates at this speed is intermittently irradiated with a lighting device such as a stroboscope at a period of 40 times / sec in a dark environment such as at night, it rotates with the tire. Six marks 4 provided at equal intervals in the inner annular region 3a are rotated 120 ° around the rotation axis of the tire each time irradiation is performed, and the marks 4 of the inner annular region 3a are circumferentially moved. Since the position coincides with the degree of irradiation, the mark 4 of the inner annular region 3a on the tire side surface 2 is the same in the tire circumferential direction as shown in FIG. It appears to be stationary in position.
On the other hand, in the central and outer annular regions 3b and 3c having a different arrangement pattern from the inner annular region 3a, the circumferential position of the mark 4 is shifted every time irradiation is performed. The mark 4 of 3b and 3c cannot be clearly recognized.

  And when the vehicle is accelerated while the cycle of irradiation to the tire side surface 2 is maintained and the traveling speed reaches 162 km / h, only the eight marks provided at equal intervals in the central annular region 3b are present. As shown in FIG. 2 (b), it seems to be stationary at the same position in the circumferential direction. Further, when the vehicle is accelerated to 172.8 km / h, only ten marks 4 in the outer annular region 3c appear to be stationary at the same circumferential position as shown in FIG. 3 (a). It becomes like this. In addition, when the vehicle is accelerated to 216 km / h, the marks 4 of all the annular regions 3a, 3b, and 3c appear to stand still at the same position in the circumferential direction as shown in FIG. 3 (b). become.

In the irradiation method described above, the color, shading, font, etc. of the characters constituting the mark 4 can be made different between the annular regions 3a, 3b, 3c of the tire side surface 2, It is easy to grasp the traveling speed of the vehicle by viewing the tire side surface 2.
In addition, although illustration is abbreviate | omitted, at least one part of the display provided in cyclic | annular area | region 3a, 3b, 3c can also be made into a figure, a symbol, etc.

  By the way, when the illuminating device used for irradiating the tire side surface 2 is installed on the ground stand 5 of the circuit illustrated in FIG. It becomes possible to irradiate the tire side surface simultaneously, and when each vehicle is equipped with the tire 1 having the same specification as shown in FIG. 1, the vehicle travels when the tire side surface 2 is visually observed from the outside of the vehicle. Since the positions of the annular regions 3a, 3b, and 3c that appear to be stationary differ between the high-speed vehicle and the low-speed vehicle, the traveling speed of each vehicle can be visually recognized.

FIG. 5 shows a tire 11 that can be used in another irradiation method of the present invention.
Here, in the illustrated tire 11, 16 figures 13 that deform the human body and express limbs like sticks are provided on the side surface 12 of the tire 11 at equal intervals in the tire circumferential direction. Are arranged at a pitch of 22.5 ° around the tire rotation axis in the tire circumferential direction. Here, for each of the four figures arranged in the tire circumferential direction, each form is gradually changed toward the one side in the tire rotation direction.
In addition, although illustration is abbreviate | omitted, at least one part of the display provided in the side surface 12 of the tire 11 can also be made into a character, a symbol, etc.

Here, another irradiation method of the present invention using the tire 11 shown in FIG. 5 is, for example, when a vehicle (not shown) in which the tire 11 in the rim assembly posture is mounted on the vehicle is driven at night and the vehicle is traveling. The side surface 12 of the rotating tire 11 can be irradiated intermittently in synchronization with the rotation of the tire 11 by a lighting device (not shown) installed outside the vehicle.
By adjusting the period of irradiation by the lighting device, for example, by irradiating the tire 11 once every 22.5 ° around the rotation axis, the figure 13 on the tire side surface 12 is displayed from the outside of the vehicle. Since the figure 13 appears to change in the order indicated by the white arrow in FIG. 6 at each provided position, the moving image corresponding to the “hand” of the figure 13 representing the human body is moving. Can be recognized.
