DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to a first embodiment shown in FIGS. First, 1 is a road sign. In this embodiment, the road sign 1 is fixedly attached to an upper part of a sign post 2 erected on the side of a road via a fastening metal fitting 3 in the form of a fastening band.

The road sign 1 according to the first embodiment includes a sign plate main body 5 and a base plate 6 having a paint-like conductive heat generating layer fixedly attached to the back (rear) side of the sign plate main body 5. ,
And a power supply support member 7 fixed to the upper part of the sign plate main body 5 so as to be able to adjust its mounting position.

Therefore, a specific configuration of the road sign 1 will be described focusing on these members 5, 6, and 7. First, as shown in FIG. 1, the sign plate body 5 is formed in a U-shaped cross section as a whole in this embodiment. As is well known, the road sign 1 has a triangular shape, a circular shape, a rectangular shape, a pentagonal shape, and the like. However, the shape of the sign portion 5a of the sign plate body 5 of this embodiment is rectangular as shown in FIG. The marker plate main body 5 has a projecting wall-shaped peripheral wall portion 5b that is continuously provided in the cross direction on the back (rear) side of the marker portion 5a. A mounting hole (female screw through hole) 5c into which the angle direction adjusting fixture 8 is screwed is formed in a central portion on the upper wall side of the peripheral wall portion 5b.

Next, as shown in FIG. 1, in this embodiment, the base plate 6 is formed in a vertical cross section with a slightly inverted U shape, and is fitted and fixed in the peripheral wall portion 5b of the sign plate main body 5. Therefore, the outer diameter of the base plate 6 is almost the same as the inner diameter of the marker plate main body 5 (joined to each other).

The base plate 6 has a vertical wall portion 6a opposed to the marker portion 5a of the marker plate main body 5 via the heat insulating space 9, and is bent at upper and lower ends of the vertical wall portion 6a. And a fitting fixing portion 6b having a plurality of female screw holes 11 for fixing screws 10.

On the inner wall surface of the vertical wall portion 6a of the base plate 6, a paint-like heating element 15 which generates heat by energization and heats the sign board body 5 is entirely applied. This paint-like heating element 15 is based on an organic substance, is composed of a combination of several kinds of heating elements and inorganic substances, is dissolved in an organic solution, and is naturally dried at 20 ° C. for about 20 minutes after application. Well,
This paint-like heating element 15 is, specifically, a metal plate, a tile,
It is a polyurethane-based conductive paint (conductive material) that becomes a planar heating element only by being applied to a base plate 6 made of glass or the like, and has a very high heat generation efficiency. For example, the temperature can be set from 1 degree to 1000 degrees by changing the current and the voltage.

Two electrode plates 16, 16 are fixed to the inner wall surface of the vertical wall portion 6a of the base plate 6 via a paint-like heating element 15 at appropriate positions. One ends of the lead wires or connection cords 17 are respectively attached. And each connection code 17, 17
Is outside the base plate 6 through small holes 18, 18 appropriately formed in the base plate 6, and is electrically connected to a controller described later.

Further, a heat insulating layer 19 as an example of a heat insulating member is coated on the entire outer wall surface of the vertical wall portion 6a of the base plate 6, and a plurality of engaging support plates 20, 20 are provided at required intervals. And is fixedly disposed. Engagement support plate 2
Although there are several forms such as a lip grooved steel and a hat-shaped steel in 0, in this embodiment, a total of two horizontal support plates having a cross section or an end surface of "lip grooved steel" are employed.

Next, as shown in FIG. 4, the power supply support member 7 is a wide support plate 25 formed by bending a single plate at an acute angle.
And a solar cell 26 laid flat on the inclined upper wall portion 25a of the wide support plate 25. Wide support plate 25
Is an inclined upper wall portion 25a provided with a solar cell 26,
And a lower wall 25b positioned horizontally with respect to the inclined upper wall 25a. A penetrating horizontal slot 27 is formed. In addition, the weather is “snow” on the outer wall surface of the bent portion of the wide support plate 25.
, The snow adhesion detector 28 on condition of snow adhesion
Is fixedly provided.

The controller 30 electrically connected to the snow adhesion detector 28 is provided on the inclined upper wall 25 of the wide support plate 25.
a and the lower wall 25b, and the two electrode plates 1 are connected via the connection cords 17 and 17 described above.
6 and 16 are electrically connected. The controller 30
Is electrically connected to the solar cell 26 of the power supply support member 7 through the power cord 31 and is connected to the upper part of the sign support 2 via the fixing means 32.
Are also electrically connected via the second connection cord 34.

Although not shown, the controller 30 controls the temperature of the switch member, the timer, and the paint-like heating element 15 which operate so as to be energized by the detection signal of the snow adhesion detector 28 to a required heating temperature. It has a control unit and the like.

In the above configuration, the road sign 1 is fixedly attached to the sign post 2 via the attachment fitting 3 which engages with the engagement support plate 20 of the base plate 6. Next, when it is desired to set the position (direction) of the power supply support member 7 in a desired state in relation to the sunlight before completely screwing the angle direction or position direction adjusting fixture 8 into the mounting hole 5c. , The direction (for example, facing south), and then the wide support plate 2
5 is rotated in the horizontal direction, and the fixture 8 is tightened. Then, as shown in FIG. 5, the solar cell 26 of the power supply supporting member 7 is set in a desired direction. Next, the controller 30 of the power supply supporting member 7 and the power storage means 33 are electrically connected via the second connection cord 34 as shown in FIG.

If the snow falls and a certain amount of snow adheres to the snow adhesion detector 28 of the power supply support member 7, the state is detected by the detector 28. Therefore, upon receiving the detection signal, the controller 30 turns on the switch member via the control unit, and starts energizing the heating element 15. And
The temperature and the heating time of the heating element 15 are appropriately controlled by a timer. When the heating element 15 generates heat, the base plate 6 is naturally heated, and the marker main body 5 is heated via the base plate 6. Therefore, the snow attached to the surface of the marker body 5 is melted.

By the way, when the heating element 15 generates heat, the heat insulating space 9 in the road sign 1 is warmed, but the timer operates to turn off the switch member (not energized).
In this case, since the temperature of the heat insulating space 9 does not drop rapidly, the heat generating energy of the heat generating body 15 can be efficiently used by the heat insulating space 9 and the heat insulating layer 19.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the first embodiment described in the embodiment of the present invention, the snow adhesion detector 28 is attached to the wide support plate 25 of the power supply support member 7, but is outside the sign plate main body 5. It may be fixedly mounted on the upper wall. In addition, snow adhesion detector 2
Although the controller 30 that receives the detection signal 8 is mounted on the power supply support member 7, the controller 30 may be mounted not on the road sign 1 but on the sign post 2.

Next, another embodiment different from the first embodiment of the present invention will be described. In the description of the other embodiments, the same components as those of the first embodiment will be denoted by the same or similar reference numerals, and redundant description will be omitted.

First, the second embodiment shown in FIGS. 6 and 7 is different from the first embodiment mainly in that the paint-like heating element 15A is used.
Is not the base plate 6A, but the marker portion 5a of the marker plate main body 5A.
And the snow adhesion detector 28
A is fixedly attached to an appropriate position above the marker portion 5a of the marker plate body 5A. Even with this configuration, the first
The same operation and effect as the embodiment are obtained. The paint-like heating element 15A does not necessarily need to be entirely applied to the back surface of the marker 5a, but may be partially applied to the upper side of the back surface of the marker 5a.

Next, in the third embodiment shown in FIG.
The main difference from the embodiment is that the sign plate main body 5B and the base plate 6
B, without providing a heat-insulating space,
Are provided in a sandwich shape between the sign plate main body 5B and the base plate 6B. In this case, it is sufficient to apply the paint-like heating element 15B to either the marker plate main body 5B or the base plate 6B. In this embodiment, it is applied to the base plate 6B side. An engagement support plate 20B is integrally welded or fixed to the base plate 6B via an attachment plate 36 of an arbitrary shape.

In the third embodiment, the paint heating element 15B is provided between the marker plate body 5B and the base plate 6B in a sandwich shape. However, depending on the design, the paint heating element 15B may be used. The body 15B may be applied to the back outer surface of the base plate 6B, and the outer surface of the paint-like heating element 15B may be covered with a heat insulating member such as a heat insulating sheet, a heat insulating layer, and a heat insulating sheet. I can say.

Finally, the fourth embodiment shown in FIGS. 9 to 12 is mainly different from the first embodiment in that the road sign 1C has no base plate. Further, the paint-like heating element is not directly applied to the road sign 1C, but a separate plate-like heating member 40 is attached to the back side of the sign plate body 5C integrally or in a surface contact state. . Further, the power supply supporting member is not fixed to the upper part of the sign board main body 5C so as to be position-adjustable.

Therefore, a configuration mainly different from that of the first embodiment will be described. The sign plate body 5C is made of a single plate like a commonly used road sign. Thus, a power supply support wall 7C extending in an inclined manner is provided above the marker 5a. The power supply support wall 7C itself may be formed of a separate plate and may be integrally fixed to the marker 5a via fixing means, but in this embodiment, the marker 5a is used.
It is made by bending the upper part of. Power supply support wall 7
A solar cell 26C is fixedly laid on the upper surface of C as in the first embodiment, and a snow adhesion detector 28C is provided at an appropriate location. On the other hand, a solar cell 26C, a snow adhesion detector 28C,
A controller 30C that is electrically connected to the power storage unit 33C and the plate-shaped heat generating member 40 is fixedly attached.

The plate-like heat generating member 40 is integrally formed on the back side of the sign plate main body 5C via an engagement support plate 20C whose cross section is a hat-shaped steel or a lip grooved steel and a wedge-shaped fixing piece 41 as an example of fixing means. It is fixed to. Engagement support plate 2
Reference numeral 0C denotes a hat-shaped steel in cross section in the present embodiment, and a hand-shaped mounting bracket 3C wound around a column is engaged through two notches at the center of the engagement support plate 20C. .

As shown in FIGS. 11 and 12, the plate-like heat generating member 40 is formed in a "Y-shape" as a whole.
A contact plate 42 having an insertion portion 42a inserted into at least one end of the engagement support plate 20C for the mounting bracket 3C;
A paint-like heating element 43 applied to the inner wall surface of the abutting plate 42 in a plane; and a heat insulating layer 44 or a heat insulating sheet provided on the outer wall surface of the abutting plate 42 in a planar manner. And two electrode plates 16C, 16C are appropriately attached to the paint-like heating element 43. Then, the plate-like heating member 40
In the present embodiment, as shown in FIG. 10, each is inserted and fixed to both ends of the upper engaging support plate 20C, and
They are connected to the controller 30C via connection cords 17C, 17C, respectively.

In this embodiment, the shape of the plate-like heat generating member 40 is "Y-shaped". However, in accordance with the shape of the sign 5a of the road sign 1C, for example, an L-shaped, The design can be changed as appropriate, such as a U-shape or a long plate.

In the above configuration, the shape of the engaging support plate 20C, such as a hat-shaped steel section and a lip-shaped grooved steel section, which is generally fixed to the back of an existing road sign, is utilized as it is, and the engaging supporting plate is first used. A plate-like heating member 4 is attached to one end of 20C.
When the wedge-shaped fixing piece 41 is driven between the outer surface of the insertion portion 42a and the inner surface of the engagement support plate 20C (clearance), the plate-shaped heat generating member 40 is inserted into the engagement support plate 20C. While being fitted and fixed, the paint-like heating element 43 is joined to the back surface of the sign plate body 5C in a surface contact state.

Therefore, when the paint-like heating element 43 generates heat, it is heated from above the marker 5a in this embodiment.

[0035]

As is clear from the above description, the present invention has the following effects. (1) Since the paint-like conductive heating element applied to the base plate or the sign plate main body is a polyurethane-based resin which becomes planar only by being applied, it is easy to manufacture a road sign. Further, since the heat generation efficiency is very high, the snow attached to the surface of the road sign can be immediately and sufficiently melted. (2) Since the heat insulating space and the heat insulating member are provided, the heat of the heat generating element can be efficiently used. (3) Since the power supply support member is fixed to the inclined upper portion of the sign plate body so as to be adjustable, natural energy can be fully utilized and running costs are low. (4) It is rich in durability. (5) In the fourth embodiment, the shape of the engagement support plate fixed to the back surface of the existing road sign can be utilized as it is. Further, since the insertion portion 42a is inserted into one end of the engagement support plate 20C, the heat generating member can be easily attached.
