Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has a light source inside and is arranged outside, such as characters, figures, symbols, pictures and patterns.
The present invention relates to an internal illumination type display device which illuminates a display body carrying visible information such as a photograph with the light source later.

[0002]

2. Description of the Related Art Conventionally, an internally illuminated display device of this type is
A plastic plate or glass plate carrying visible information was attached to a steel frame, and a light source such as a fluorescent lamp was housed inside.

[0003]

In the conventional internal illumination type display device, it is difficult to (a) appropriately exchange the visible information such as characters and figures displayed by the display body with another information.
(B) It becomes heavy and inconvenient to carry, (c)
It is easily damaged, and (d) it is dangerous when a person hits it.
There was a problem such as.

The present invention has been made in view of such circumstances, and it is possible to easily exchange the visible information such as characters and figures to be displayed for another one, which is lightweight and convenient to carry. An object of the present invention is to provide an internal lighting display device that is not easily damaged and is safe even if a person hits it.

[0005]

An internal lighting display device according to the present invention is provided between a pair of tubular members made of a translucent plastic material extending in the vertical direction on the left and right sides and between the tubular members. A light source, an inner bag made of a light-transmissive cloth material that covers the tubular material so as to accommodate the light source inside, and visible information to be displayed, which is covered on the inner bag. And an outer bag made of a translucent cloth-like material carried.

[0006]

In the internally illuminated display device according to the present invention,
The light-transmitting outer bag that carries visible information such as characters and figures is illuminated from the inside through the inner bag by the light source housed in the light-transmitting inner bag. Demonstrate.

Further, the inner bag and the outer bag are covered on a pair of translucent cylindrical members extending in the vertical direction on both left and right sides, and the light from the internal light source is exposed to the outside through the cylindrical member. Since it diverges, it is possible to diverge light not only in the front and back but also in the direction of 360 degrees, so that the visibility of the display device is very good, and the inner bag and the outer bag are double-coated. Since the inner bag is made of a durable cloth material such as tarpaulin to increase the strength of the device, the outer bag is
A cloth-like material such as vinyl suitable for carrying visible information such as a figure can be used.

Further, by exchanging the outer bag, it is possible to easily exchange the visible information such as characters and figures to be displayed with another one.

Further, since it can be made lightweight, it is convenient to carry and can be used at a construction site or the like. Furthermore, since visible information such as characters and figures is carried by a bag made of cloth-like material instead of a plastic plate or a glass plate, it is hard to be damaged. Further, since the inner bag and the outer bag made of the cloth-like material are covered with the cylindrical material made of the plastic material, it is safe even if a person hits.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on the embodiments shown in the drawings. 1 to 10 show a first embodiment of an internally illuminated display device according to the present invention. 1 to 3 show a state in which the inner bag 1 and the outer bag 2 are removed in the first embodiment, and a column 5 provided with casters 3 is provided with columns 5 standing up and down. An upper tubular material support plate 6 protruding in both left and right directions is fixed to the upper end of the column 5, and a lower tubular material support plate 7 protruding in both left and right directions is fixed to the lower end side. A pair of left and right tubular members 8 are fixed between the left and right ends of the upper and lower tubular member support plates 6 and 7 so as to extend in the vertical direction. These tubular members 8 are each made of a translucent plastic material such as acrylic resin. A pair of fluorescent lamp units 9 are attached to the left and right side surfaces of the column 5. These fluorescent lamp units 9 include a unit body 10, a fluorescent lamp 11, and a ballast 12 for lighting the fluorescent lamp 11, and the like.
The fluorescent lamp 11 extends vertically between the tubular members 8.

FIG. 4 shows the inner bag 1, which is made of a durable cloth-like material such as translucent tarpaulin,
It has an opening at the lower end. At the lower ends of the front surface and the back surface of the inner bag 1, one side of the chevron-shaped tension member 13 is attached to the bolt 1.
4 and nuts 15 (see FIG. 7), and bolt holes 16 are provided on the other side of the tension member 13. When the inner bag 1 is tensioned by fastening the front and back side tension members 13 of the inner bag 1 to the portions of the inner bag 1 on both sides of the tension member 13 attachment portion, as will be described later in detail. In addition, a cut 50 is provided so that the attaching portion of the tension member 13 of the inner bag 1 can be easily bent.

FIG. 5 shows the outer bag 2, which is made of a cloth material such as a vinyl sheet and has an opening at the lower end. Visible information 20 such as characters, figures, symbols, pictures, patterns and photographs is provided on the front surface and the back surface of the outer bag 2 by printing or bonding.

The tubular member 8, the upper tubular member supporting plate 6 and the lower tubular member supporting plate 7 are, as shown in FIGS.
The inner bag 1 is covered. Then, as shown in FIG.
The bolts 17 are inserted into the bolt holes 16 of the tension members 13 on the front side and the back side, and the nuts 18
By screwing together and tightening the nut 18, the lower ends of the front surface and the back surface of the inner bag 1 are brought close to each other, and the inner bag 1 is pulled downward and tensioned, and slack and wrinkles are removed. The inner bag 1 thus tensioned is further covered with an outer bag 2, as shown in FIGS. 9 and 10.

In this internal illumination type display device, the translucent outer bag 2 carrying the visible information 20 such as characters and figures is
The fluorescent lamp 11 (light source) housed in the translucent inner bag 1 is illuminated from the inside through the inner bag 1 to exhibit an excellent display effect.

Further, since the inner bag 1 and the outer bag 2 are covered with a pair of light-transmissive cylindrical members 8 extending in the vertical direction on both left and right sides, the light from the internal fluorescent lamp 11 is cylindrical. Since the light radiates to the outside through the material, the light can be radiated not only in the front surface and the back surface but also in the direction of 360 degrees, and thus the visibility of the display device is very good.

Further, since the inner bag 1 and the outer bag 2 are double-covered, a strong cloth-like material such as tarpaulin is used for the inner bag 1 to enhance the strength of the apparatus. Outer bag 2
A cloth-like material such as vinyl suitable for carrying the visible information 20 such as characters and figures can be used. Then, by exchanging the outer bag 2 with another outer bag 2 carrying another visible information, the visible information 20 to be displayed can be exchanged with another very easily.

Further, since it is lightweight, it is convenient to carry. Further, since the bag 2 made of cloth-like material carries the visible information 20 such as characters and figures, not the plastic plate or the glass plate, the display device is not easily damaged. Further, since the inner bag 1 and the outer bag 2 made of a cloth-like material are covered with the cylindrical material 8 made of a plastic material, it is safe even if a person hits.
