Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The railroad wheel and tire wear degree display device of the present invention has a blue and a part of the tread portion of the wheel and tire as an indication according to the wear degree on the whole surface or a part of the tread portion of the wheel and tire. By incorporating a color-coded display in yellow and red to display safety, caution, and danger warnings that correspond to the degree of wear, the driver and the operation manager can use the wheels and tires for their respective purposes and purposes. It is possible to easily and clearly grasp the replacement time according to the above. By detecting wear and abnormal wear of wheels and tires at an early stage, it is possible to prevent accidents and reduce the number of accidents by using tires with wear level indication, risk level indication, or safety level indication, in other words, blue.・ Wheels and tires with safety, caution, and danger warning displays in yellow and red.

[0002]

[Prior art]

 The conventional tire shown in FIG. 12 is referred to as a slip sign 13 and is indicated by a method in which a tread and an adjacent tread are laterally connected in the same tread pattern due to wear of the tread.

[0003]

[Problems to be solved by the device]

 The slip sign described in the related art was displayed from the beginning, and even if the slip sign appears due to the use of tires, it is not noticed to the general driver and many people are interested. It had a problem that it was unhelpful.

[0004] Furthermore, the wheels for railways do not have the display, and have a problem that they depend on the feeling of the expert.

The present invention has been made in view of the above problems of the conventional technique, and an object of the present invention is to make a wheel, a tire, a blue, a yellow, or a red, depending on the degree of wear thereof. In other words, by displaying the safety, caution, and danger warnings in different colors, the driver and operation manager can easily and clearly grasp the replacement time of the wheels and tires according to their respective uses and purposes. The present invention intends to provide a wheel and a tire with a wear degree display device, which can achieve the above.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the wear degree display device in the present invention is divided into blue, yellow, and red on the whole or a part of the surface of the wheel and the tread portion of the tire as an indication according to the wear degree. By incorporating the display, safety, caution, and danger warnings corresponding to the degree of wear are displayed in different colors.

This wear level display device has a substantially trapezoidal conical shape for preventing falling off, and the lower part 11 is slightly larger than the upper part 10.

In addition to the substantially trapezoidal conical shape, a * ◆ * cylindrical shape may be used, and a strip shape such as a triangle may be embedded in the entire tread surrounding the tire.

As the material of the wear degree display device, a material that is easily colored and has the same or similar properties as those of the material of the wheel or the tire is used.

[0010]

[Action]

 When assembling the wear degree indicating device, not only is it assembled in the manufacturing process, but in the case of a tire, a plurality of spikes may be installed by using the existing spike holes in the same manner as spike tires. Therefore, the bottom portion 12 of the wear degree indicating device is formed into a fan shape or a semi-elliptical shape to facilitate insertion. In addition, the wheel can be worn by tapping a hole with a spiral groove and attaching a thread to the wear indicator.

[0011]

【Example】

 Examples will be described with reference to the drawings. 3 to 6, in the case of a tire, the wear degree indicating device A is made of a soft resin such as vinyl and is formed into a substantially trapezoidal conical shape having a diameter of about 5 mm to 10 mm. More specifically, the cross-sectional shape is substantially trapezoidal, and slightly widened toward the lower portion 11 to prevent separation due to centrifugal force or the like during high-speed rotation.

Further, in order to incorporate the wear degree indicating device after the tire is manufactured, it may be molded so as to match the structure of the hole of the conventional spike tire. In that case, the bottom portion 12 of the wear degree indicating device 4 is formed into a fan shape, a semi-elliptical shape or the like to facilitate the insertion.

Further, the wear degree display device A is composed of layers of three colors of blue 7, yellow 8 and red 9 in order from the upper portion 11, and the contacting portions of the layers are sloped as shown in FIGS. 5 and 6. .

As the wheels and tires are used, the wear degree display device gradually wears as shown in FIGS. The display of the wear degree display device at that time is as shown in FIGS.

Further details will be described with reference to FIGS. 7 and 8. When it is worn out to the position a in FIG. 7, only "safe" blue is displayed as shown in a in FIG.

When the wear occurs up to the position of B in FIG. 7, as shown in B of FIG. 8, the amount of blue decreases and the amount of yellow “caution” occupies most.

When the wear occurs up to the position of C in FIG. 7, as shown in C of FIG. 8, a red “danger” starts to appear.

When the wear reaches the position of D in FIG. 7, as shown in D of FIG. 8, only “red” is displayed.

Further, as shown in FIGS. 9 and 10, a second wear degree display device C can be incorporated outside the first wear degree display device B to form a double wear degree display device. In this way, various information can be provided by various combinations.

For example, as shown in FIG. 10, the outer side is a snowy or wet road surface wear degree display device C 2, which has two colors, blue and red. The inside is used as a dry road surface wear degree display device B to enable independent display of each. In this case, the display of the wear degree display device according to the degree of wear is as shown in FIGS.

Details will be described with reference to FIGS. 10 and 11. At the position of Fig. 10E, as shown in Fig. 11E, the "dangerous" red begins to appear on the snow or wet road surface wear degree display device C, but the dry road surface wear degree display device B is blue. Remains "safe".

At the position shown in FIG. 10, as shown in FIG. 11, red appears in the middle of the wear degree display device C for snow or wet road surface, indicating that it is quite dangerous. The yellow “Caution” occupies most of the road B, and it is a little caution.

At the position of FIG. 10G, as shown in FIG. 11G, the degree of danger of the wear degree display device C for snow or wet road surface is increased, and the dry road surface B is also a caution display.

At the position of FIG. 10C, as shown in FIG. 11C, the wear degree display device C for snow or wet road surface is very dangerous and informs the tire replacement time. For road use, it is only usable until the red color has finally begun to appear.

As described above, the B and C two wear degree display devices can display each independently. This double wear degree display device may use a shape such as ★ ◆ * to clarify its distinction from other wear degree display devices.

[Effect of device]

 Since the present invention is configured as described above, it has the following effects.

In the wear degree display device according to the first aspect, it is possible to grasp the wear degree of the wheel or the tire clearly, very easily and clearly by color.

In the dual wear degree display device according to the second aspect, it is possible to display and provide a plurality of information.
