[Action and effect]

 That is, according to the guardrail cover of the present invention, it is possible to clean a guardrail that has become completely black due to long-term use in a short time simply by attaching it to the guardrail. In other words, unlike painting and replacing, it does not take a construction period and costs can be kept low. For this reason, it is possible to ensure that the function of safe operation of the vehicle is fulfilled, which greatly contributes to the control of accidents.

Moreover, not only can it be attached to a dirty guardrail, but it can also be easily repaired if it is attached to a new guardrail, and the guardrail can be protected from rust due to rain, etc. The life can be extended and the above effects can be exhibited for a long time.

When the guardrail cover is made of synthetic resin and is fitted to the locking piece as in the structure of claim 2, the mounting work can be performed very easily. At the same time, the cost can be suppressed.

In the case of being formed of two kinds of synthetic resins having different colors and properties as in the structure of claim 3, the following effects can be achieved. That is, when the color is changed, the labor for coloring can be saved, and when the property, for example, the hardness is changed, the fitting work can be facilitated.

In the case of the structure of claim 4, in addition to the coloring of the guardrail cover itself, it is possible to draw the driver's attention or call attention by the marking, which is more safe. You can try to protect the operation.

When the film having the marking is polymerized during extrusion molding of the guardrail cover as in the structure of claim 5, the effect achieved by the guardrail of claim 4 can be easily produced. Can be obtained by

Further, when the reflecting device is attached to the guardrail cover as in the sixth aspect, it contributes to safe operation at night.

【Example】

 An embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a perspective view of the guardrail cover 1. As shown in FIG. 1, the guardrail cover 1 is formed into a bent shape corresponding to the shape of the steel plate 2a of the guardrail 2 (see FIG. 2). The outer surface of the steel plate 2a can be attached so as to be covered along the shape of the steel plate 2a. It should be noted that the illustrated guardrail 2 is an example of various types, and the guardrail cover 1 may be formed in a predetermined shape corresponding to the guardrail 2.

The formation is performed by extruding a synthetic resin such as vinyl chloride into the predetermined shape as described above. At this time, the upper and lower edges of the guardrail cover 1 in the longitudinal direction are engaged with the upper and lower edges 2b, 2b of the steel plate 2a of the guardrail 2 to engage the guardrail cover 1 as shown in FIG. 3 and 3 are formed obliquely toward the inside. As a result, if the guardrail cover 1 is pressed straight against the steel plate 2a from the front, the guardrail cover 1 can be fitted by the material elasticity of the synthetic resin. Alternatively, the upper and lower one of the locking pieces 3 may be locked first, and then the other locking piece 3 may be locked.

In addition, in extrusion molding, as shown in FIG. 1, the resin sheet 4 is polymerized on the surface immediately after extrusion. The resin sheet 4 is provided with a sign 5 for indicating cautions during operation by printing or printing. This sign 5 is, for example, a character such as "no parking", "no overtaking", or "speed down" as shown in Fig. 1, or a black diagonal line on a yellow background as shown in Fig. 4. It is the pattern that is given, or roughly all the characters and patterns that should be marked on the guardrail.

The guard rail cover 1 may be long so as to correspond to the steel plate 2a of the guard rail 2 (for example, about 4 m), or may be as short as about 90 cm. When the length is long, the appearance is good, and when the length is short, the handling such as transportation is good.

FIG. 5 is a perspective view showing a state in which the guardrail cover 1 is attached. The guardrail cover 1 attached to the curved steel plate 2a at the end of the guardrail 2 is extrusion-molded and then rolled. It can be formed by processing.

With the guardrail cover 1 having the above-described structure, the guardrail 2 that has been blackened for a long time can be cleaned in a short time only by attaching it to the steel plate 2a of the guardrail 2. In other words, unlike painting and replacing, it does not take a construction period and costs can be kept low. For this reason, it is possible to ensure that the function of safe operation of the vehicle is fulfilled, which greatly contributes to the control of accidents.

Further, not only is it attached to the dirty guardrail 2 but also to a new guardrail 2 not only is it easy to repair, but also the guardrail 2 can be protected from rust due to rain or the like. The life of the guardrail 2 can be extended, and the above-mentioned effects can be exhibited for a long period of time.

Further, since the guard rail cover 1 is made of synthetic resin and can be fitted therein, the mounting work is extremely easy and the cost can be suppressed.

Further, since the resin sheet 4 having the marking 5 is superposed on the surface of the guardrail cover 1, the marking 5 attracts the driver's attention in addition to the coloring of the guardrail cover 1 itself. Can be called, and it is possible to protect even safer operation. Moreover, the resin sheet 4 is polymerized at the time of extrusion molding of the guardrail cover 1, so that it is easy to manufacture.

FIGS. 6, 7, and 8 show a guardrail cover 1 according to another embodiment. The guardrail cover 1 in FIG. 6 shows an example in which extrusion molding is performed by simultaneously extruding two kinds of synthetic resins 6 and 7 of different colors. In this case, the labor of coloring can be saved. Alternatively, synthetic resin having different hardness may be used. For example, when soft synthetic resin is formed in the portions connected to the locking pieces 3 and 3 at the upper and lower end edges, elasticity is increased to facilitate fitting work. be able to.

FIG. 7 and FIG. 8 show an example in which a reflecting device is attached to the guardrail cover 1.

The reflecting device shown in FIG. 7 is composed of reflecting pieces 8 of glass or plastic and is attached to the surface of the guard rail cover 1. Adhesion may be carried out during extrusion or via an adhesive after molding.

The reflector shown in FIG. 8 is composed of a diamond-cut glass reflector 9 and is mounted with a screw or an adhesive after molding. When the reflecting means (reflective piece 8 and diamond-cut glass reflector 9) is mounted as described above, it also contributes to safe operation at night.
