Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a step structure used on a platform such as a station and a step material used for the step structure.

[0002]

2. Description of the Related Art FIG. 1 shows steps in a platform for getting on and off a train or the like. As shown in the figure, the conventional platform has curbs (also referred to as capstones) arranged and fixed to the edge of the platform in rows. These curbs extend slightly outward from the edge of the platform and are fixed, providing a step for getting on and off.
Therefore, the curb must have a certain level of durability to withstand wind pressure, rain, and snow when the train runs, and stone materials have been used in the past. A stone material is suitable as such a curb because it has a certain degree of hardness and weight.

[0003]

However, when the step portion of the platform for getting on and off is formed of stone as described above, there are the following problems. In other words, each time you get on and off, you will be on the step section,
The step part is hard in material and has no cushioning property, so it is easy to give an impact. In addition, some stone materials, such as sandstone, are vulnerable to wind and rain, and may collapse in a few years.

Further, in the snowy region, when snow is accumulated on the platform, the snow is removed on the platform, especially on the boarding / alighting portion. However, when the step is stone, the snow is stuck on the curb and cannot be completely removed. This is because snow solidifies and adheres to the curb in the form of ice, and when the outside air temperature becomes low, it tends to adhere to the curb. People get on and off the platform frequently, so it is very dangerous to have snow or ice on it. Therefore, special attention is paid to snow removal from platforms at stations in snowy areas.

The present invention has been made in view of the above problems, and can be applied to a platform for getting on and off trains, can be used safely and suitably, and is easy to handle. The purpose is to provide a step material.

[0006]

The present invention has the following constitution in order to achieve the above object. That is, it is a step structure provided in the curb portion of the platform, is formed in a block shape of the same shape as the curb, a plurality of grooves are provided on the bottom surface in parallel with the front edge of the curb, and integrally formed by a rubber material. The step material fits the projecting edge in the groove on a platform of a platform in which the projecting edge that fits in the groove parallel to the front edge of the curb is provided on the mounting surface on which the step material is placed. It is characterized by being fixedly installed. Further, a flow path pipe for allowing a heat medium to flow therethrough is provided in a groove provided on the bottom surface of the step material, and the heated heat medium can flow through the flow path pipe. Further, a step material used in the step structure of the platform, using a rubber material, a plurality of grooves are provided on the bottom surface in parallel with the front edge of the curb and the same shape as the curb provided in the curb portion of the platform. It is characterized by being integrally molded into a block shape. In addition, the step material is integrally formed by an outer layer portion formed of a colored rubber of a predetermined color and an inner layer portion formed of a cushioning rubber.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings. FIG. 1 is an explanatory view showing a platform for getting on and off a station, and shows a state in which step members 10a, 10b made of a rubber material are attached to the platform for getting on and off. The step materials 10a and 10b are formed in a block shape having the same shape as that of a conventional curb, and are installed in combination with a curb 12 which is conventionally used. In the embodiment, the step members 10a and 10b are arranged according to the boarding / alighting position of the train, but they may be installed over the entire length of the curb portion of the platform.

FIG. 2 shows the structure of the step members 10a and 10b. As described above, the step members 10a and 10b are integrally formed by using a rubber material, but the top and bottom of the step members 10a and 10b, that is, the step surface during slip forming, has an uneven pattern and a boarding / alighting position to prevent slippage. Form the letter. In the embodiment, the step material 10 is provided at one boarding / alighting position.
Although a and 10b were used in combination as a pair, the end surfaces of the step materials 10a and 10b were fitted in a concavo-convex shape so that they could be surely combined. For this reason, the fitting groove 14a is provided on the combination surface of the one step material 10a, and the projection 14b that fits into the fitting groove 14a is provided on the combination surface of the other step material 10b.

A plurality of grooves 16 are provided on the bottom surfaces of the step members 10a and 10b. These grooves 16 are formed by step materials 10a, 1
It is provided in order to install 0b without shifting the position. FIG. 3 shows a cross-sectional view of the step material attached to the substrate 18. The base 18 is provided with a projecting edge 18a that fits into the groove 16 provided on the bottom surface of the step members 10a, 10b, and the groove 1 is formed when the step members 10a, 10b are installed on the base 18.
6 and the protruding edge 18a are fitted and fixed. When the step materials 10a and 10b were actually installed, an adhesive was put in and the base 18 and the step materials 10a and 10b were bonded and fixed. As a result, the step materials 10a and 10b could be fixed semipermanently.

The grooves 16 provided on the bottom surfaces of the step members 10a and 10b are provided parallel to the front edges of the step members 10a and 10b, and the projecting edge 18a provided on the base 18 is also provided parallel to the edge of the platform. When the step materials 10a and 10b are placed, the groove 16 and the projecting edge 18a have the projecting edge 18a.
By wedge-like insertion into the inside, it securely engages with the base 18, and acts to firmly fix the step materials 10a and 10b to the base 18, and at the same time, the step materials 10a and 10b are displaced in the front-rear direction. It has the effect of preventing

When the step members 10a and 10b are fixed in the longitudinal direction, the end faces of the step members 10a and 10b are butted against each other so that the projection 14b is fitted into the fitting groove 14a. For example, connecting bolts may be passed through the grooves 16 on the bottom surface of the step members 10a and 10b in the longitudinal direction to tighten the step members 10a and 10b from both sides.

The step members 10a and 10b are formed by integrally molding the groove 16 and the like using a rubber material. However, in order to clearly indicate the boarding / alighting position, it is more effective by coloring them in green, blue, yellow, red or the like. Can be used. FIG. 3 shows the step material 10a,
An example is shown in which the colored rubber 20 is used for the outer layer portion of 10b and the cushioning rubber 22 is provided for the inner layer portion of the molded article 10b. Any color can be selected as the color of the colored rubber 20, but since the current colored rubber is slightly inferior in strain resistance, a colored rubber is used for the surface portion and good cushioning and strain resistance are used for the inside. It is preferable to use some cushioning rubber 22. Of course, at the time of molding, the colored rubber 20 and the buffer rubber 22 are integrally molded.

When the step members 10a and 10b are made of a rubber material as described above, it is possible to display an arbitrary color by using a colored rubber. Therefore, it is very effective for displaying a boarding / alighting position. . In addition, there is no concern that the color will fall off as in the case of displaying with paint or the like, and there is an advantage that maintenance after mounting becomes easy. Further, by using a durable rubber material, it is possible to obtain durability higher than that of the conventional stone material. Further, since the step members 10a and 10b have a certain cushioning property, the impact applied to the human body when getting on and off the vehicle can be suppressed, and a soft feeling can be obtained, which is easy to use. Further, since it is made of rubber, there is an advantage that it is unlikely to slip when stepping, and that getting on and off is safe.

It is particularly effective when snow is accumulated in the winter. This is because the step materials 10a and 10b are made of rubber and are poor conductors of heat, so that ice and snow is unlikely to adhere thereto, and ice snow and snow that have once adhered can be easily separated. If ice or snow adheres, it can be easily peeled off by the elasticity of the rubber material by hitting the step part several times. If the ice and snow are peeled off to expose the surface of the step material, the rubber material prevents slipping, so that the user can get on and off safely.

As a method for further facilitating the removal of snow during the winter season, a channel pipe such as a high-pressure rubber hose or a metal pipe is passed through the groove 16 provided on the bottom surface of the step members 10a and 10b, and added to these channel pipes. It is also possible to let the heated heat medium flow through and positively melt the snow. Since the step materials 10a and 10b are poor conductors of heat, heat is radiated only gradually from this portion, and a suitable snow melting action can be performed by gradually warming the step materials 10a and 10b.

Further, as another application utilizing the fact that the step materials 10a and 10b are electrical insulators, it is conceivable to incorporate an electronic device inside the step materials 10a and 10b. For example, there is a method of using a built-in alarm device to notify passengers that a train is approaching. For this, a method of sending data such as vibration when a train approaches to an alarm device built in the step materials 10a and 10b from a rail to activate the alarm device is considered.

The above embodiment is an example in which the step material is attached to the curb portion of the train platform, but the use of the step material having the above configuration is not necessarily limited to the platform for getting on and off the train. For example, it can be applied to a yard for train freight, or can be applied to a platform used for loading and unloading cargo such as trucks. Further, the shape, size, etc. of the step material can be appropriately set. In the above-mentioned embodiment, two step materials are connected to each other, but three or more can be connected to form one set, or a plurality of rows. It is also possible to install them side by side.

[0019]

According to the step structure of the platform of the present invention, as described above, it is possible to provide a safe and easy-to-use step structure by preventing slipping at the step portion. Further, by using a step material made of a rubber material, it is possible to obtain cushioning properties, and by coloring it, it is possible to obtain suitable effects such as suitable display.
