Description

[Detailed explanation of the idea] The present invention relates to a two-sided sign equipped with an illumination light.

Conventional signs equipped with illumination lights that illuminate the marking part, such as those used at some bus stops, place a fluorescent light in the center of the marking part and cover the front, back, left, and right sides with translucent sign boards. However, for those with a dihedral structure in which the marking part is plate-shaped, it is not possible to place a fluorescent light inside the marking part, and it is not possible to place a fluorescent light outside the marking part. Because of the risk of accidental or intentional damage, there are no structures equipped with fluorescent lights, and therefore signs that require illumination must have a dihedral (two-sided display type) sign. Tetrahedral markings were used even when it was sufficient.

However, the structure of tetrahedral signs is more complex than that of dihedral signs.
There were drawbacks such as high cost and the need for a large installation area, so there was a desire to develop a dihedral sign equipped with an illumination light.

The present invention provides a dihedral sign equipped with an illumination light in a compact and hard-to-break state, and will be explained with reference to the drawings as follows.

Figure 1 is a front view of a dihedral sign, in which the lower parts of a pair of vertical supports 1 spaced apart in the horizontal direction are buried in a concrete base 2, and the upper and middle parts are spaced apart vertically. are connected to each other by horizontal members separated by upper furring 3 (cover), intermediate furring 4 (3 pieces), and lower furring 5,
A sign plate 8 made of synthetic resin is fitted into each frame formed by the column 1 and the rims 3, 4.5.

Reference numeral 10 denotes a ridge that is snap-fitted to the upper or lower surface of the intermediate and lower furring edges 4, 5, and abuts against the upper or lower edge of the sign plate 8 to support the sign plate 8 so that it does not come off.

The strut 1, each of the edges 3, 4, 5, and the ridge 10 are made of extruded aluminum, and the strut 1 and the intermediate and lower edges 4 are made of extruded aluminum.
, 5 are connected by rivets via small metal fittings (not shown).

The upper furring 3 simply fits into the upper end of the column 1.

As shown in FIG. 2, which is a sectional view taken along line II-II in FIG. 1, the support column 1 has a cross-sectional shape that opens toward the sign plate 8 side.

Two signboards 8 are provided for each frame portion, sandwiching aluminum core plates 11 that are slightly wider than the signboard 8, and the side edges of the signboards 8, together with the side edges of the coreboard 11, are connected to the two sides of the bar-like member 12a. Step groove 12
I'm stuck in it.

The member 12a extends vertically and corresponds to lll-II in FIG.
As shown in FIG. 3, which is a view in the direction of arrow I, its lower end is fastened to a horizontal lower stop plate 30 fixed in the opening of the column 1 with two screws 31, and its upper end is fastened with two screws 31 to the upper rim 3. It is fastened with screws 32.

A rod-shaped fluorescent light 15 is installed vertically approximately at the center of the opening of each support 1.

A total of four pairs of fluorescent lights 15 are provided at positions corresponding to each sign board 8, and an electric cord is passed through a hole in the post 1.

A socket 17 is fitted into a groove 18 on the inner surface of the column.

The groove 18 is provided at the center of the inner surface of the column 1, and both sides 20 of the inner surface are inclined so that the portion 20a near the opening end is closer to the sign plate 8, so that the light from the fluorescent light 15 is A portion of the light is reflected by the both sides 20 and travels toward the surfaces of both sign boards 8.

The opening of the support column 1 is covered with a transparent vinyl plate 23 (transparent member).

Both side edges of the transparent vinyl plate 23 fit into grooves 22 provided in the open end of the support 1 and the crosspiece member 12a, and the light from the reflective surface (inner side part 20) passes through the vinyl plate 23. Both sign boards 8 are illuminated.

To replace the fluorescent light 15, use the upper and lower screws 32 and 31 in Figure 3.
, and pull out the bar-shaped member 12a upward (leaving the upper body rim 3 removed), and then remove the transparent vinyl plate 23 and the core plate 11.
After removing the sign board 8, do this from inside the open sign frame.

Note that the intermediate and lower furring edges 4 and 5 are inserted into the opening of the support column 1.

To explain the case where the sign plate 8 and the core plate 11 are replaced, the sign plate 8 is replaced with the groove 1 by removing the ridge 10 and elastically deforming it.
2, the core plate 11 can be removed from the frame (between the supports 1), and the core plate 11 can be removed from the lower and upper body edges 5, 4 in sequence.
slit (usually closed with a stopper)
It can be removed from between the pillars 1 by lowering it through the lower body rim 5 and moving one side edge into the pillar 1.The installation of the sign plate 8 and core plate 11 is done by following the steps opposite to the above. It is supposed to be done in

Therefore, these replacement operations can be performed regardless of the presence or absence of the fluorescent light 15.

As explained above, according to the present invention, the fluorescent light 15 is disposed within the opening of the support post 1, and the light from the fluorescent light 15 is transmitted to the vinyl board 22.
Since it is made to pass through and hit the sign board 8, it is possible to construct a compact dihedral sign that is equipped with an illumination light and is as compact as the conventional one.

Further, the effects of the present invention will be explained in more detail as follows.

In the present invention, a fluorescent light 15 is installed on the inner surface of a pair of vertical pillars 1 which face each other and have an open cross section.

Since the fluorescent light 15 is housed in the pillar 1 in this way,
The overall structure is compact.

In other words, the post 1 functions not only as a frame for the entire sign but also as a case for the fluorescent light 15, so that the overall structure can be made compact.

Moreover, the light emitted by the fluorescent light 15 is transmitted to both sides of the sign board 8 (core board 1
The reflective surface (
Since the inner side part 20) is provided on the inner surface of the column 1, the fluorescent light 1
Despite the fact that 5 was housed in pillar 1, the signboards 8 on both sides
, 8 can be sufficiently illuminated.

In other words, the overall structure can be made more compact and the illumination capacity can be sufficiently increased.

The fluorescent light 15 is housed in the pillar 1, and the fluorescent light installation space of the pillar 1 is covered with a vinyl board 23 (transparent member) from the sign board 8 side.
It is blocked by

Therefore, the fluorescent light 15 can be protected all around by the pillar 1 and the vinyl plate 23, and the fluorescent light 15 can be prevented from being damaged by accident or intentionally.

The vinyl board 23 is detachably held by the side edge (groove 22) of the support column 1 and the sign board holding member 12a.

Further, the bar-like member 12a is removably provided in a vertical position between both side edges of each support column 1.

Since the bar-like member 12a is thus used both as a sign board holding member and a vinyl board holding member, the structure can be simplified in this respect as well.

Furthermore, by removing the crosspiece member 12a and the vinyl plate 23, the fluorescent lamp 15 can be removed to the side (to the left in FIG. , the fluorescent light 15 can be easily replaced.

Furthermore, in the present invention, both columns 1 are provided with fluorescent lights 15 in a vertically extending position.

Therefore, the entire height of the sign board 8 can be illuminated from both left and right sides, and the entire sign board 8 can be illuminated evenly.

The support column 1 may have a generally arcuate cross-sectional shape (double-dotted line A in FIG. 2) or a U-shape (double-dotted line B).

However, in the case of a U-shaped cross section, the reflection efficiency decreases.

It is also possible to provide two rows of fluorescent lights 15 along each transparent member 23 so that the sign board 8 can be efficiently illuminated mainly by direct light from the fluorescent lights 15.

It is also possible to install, for example, one long fluorescent light on each post 1.

The present invention is applicable to signs having a core plate replacement structure other than the above, namely a structure in which an opening is provided in one of the pillars so that the core plate can be taken out laterally, or a structure in which a slit is provided in the upper rim so that the core plate can be taken out upwards. However, in the case of the former type of sign with an opening in the support, it is necessary to fix a fluorescent light to the opening door.
