Description

The present invention relates to an advertisement display apparatus and, more particularly, to an advertisement display apparatus having a combination of a front display plate and a rear display plate each having an advertisement display pattern provided thereon, the display plates being adapted to be illuminated selectively to present various advertisement displays.
Hitherto, there have been various types of advertisement display apparatus capable of presenting various advertisement displays by a single unit.
For instance, such an advertisement display apparatus is known as having a plurality of display plates which are automatically and selectively driven to and from the visible position by a suitable driving means. Another known apparatus employs a plurality of neon tubes which are turned on selectively to provide a large variety of display patterns. It is also known to use a movie film for projecting a moving image on a screen. Still another type of advertisement display apparatus employs an endless display belt carrying a plurality of advertisement display patterns and adapted to be driven at a predetermined speed.
These known advertisement display apparatus, however, can provide only comparatively monotonous changes of display pattern. The apparatus employing the movie film, which seems to provide a comparatively flexible change of pattern, requires a large installation space because it is necessary to provide a considerable distance between the movie projector and the screen.
It is, therefore, an object of the present invention to provide an improved advertisement display apparatus which mitigates the above described problems of the prior art.
According to the present invention, there is provided an advertisement display apparatus having a combination of advertisement display plates characterised in that the apparatus comprises a front advertisement display plate and a rear advertisement display plate, said front advertisement display plate being formed of a plurality of relatively transparent areas and a plurality of relatively opaque areas and provided with an advertisement display pattern such as letters, figures, signs, patterns or combinations thereof provided on the outer surface thereof, said rear advertisement display plate provided with advertisement display pattern such as letters, figures, signs, patterns or combinations thereof, said rear advertisement display plate being positioned adjacent the rear side of said front advertisement display plate; and front and rear illumination means adapted to illuminate said front and rear advertisement display plates respectively and selectively and independently, the distribution and ratio of the relatively transparent to the relatively opaque areas being such that the advertisement display pattern of the rear display plate can be recognisably distinguished through the front display plate, when illuminated by the rear illumination means.
Preferably the advertisement display apparatus comprises a front advertisement display plate made of an opaque material and having a multiplicity of small.apertures distributed evenly over the entire surface thereof and provided on its outer surface with an advertisement display pattern such as letters, figures, signs, patterns or combinations thereof, or a front advertisement display plate made of a transparent material and having a multiplicity of small opaque patches adhered to the outer surface thereof and having an advertisement display pattern such as letters, figures, signs, patterns or combinations thereof; a rear advertisement display plate made of a transparent or milk-white translucent material and provided on its inner surface with an advertisement display pattern such as letters, figures, signs, patterns or combinations thereof, or a movable elongated sheet, said rear advertisement display plate or said movable elongated sheet being disposed at the rear side of the front advertisement display plate to form, in combination with the latter, an advertisement display plate unit which is installed substantially at the central portion of a frame; and illuminating means for illuminating the front advertisement display plate and the rear advertisement display plate or the elongated sheet selectively and independently of each other.

Referring first to Figures 1 to 5 showing a first embodiment of the invention, a front advertisement display plate (referred to simply as "front plate", hereinunder) designated by a reference numeral 3 is made of an opaque material of a thickness ranging between 0.1 mm and 1 mm, such as a black semi-hard synthetic resin, paper or the like. An advertisement display_ pattern 2 such as letters, figures, signs or combinations thereof is provided on the outer surface 1 of the front plate 3. The front plate 3 is further provided with a multiplicity of small apertures 5 formed therein at a constant pitch of about 1.5 to 2.0 mm as measured at the centres of the apertures.
A rear advertisement display plate 8 (referred to simply as "rear plate", hereinafter) is made of a transparent or white translucent material, and is provided thereon with an opaque or coloured advertisement display pattern 7 such as letters, figures, signs or combinations thereof. The rear plate 8. is disposed at the rear side of the front plate 3 and is secured to the latter thereby to form an advertisement display plate unit (referred to simply as "plate unit", hereinunder). The plate unit is mounted substantially at the centre of a frame 4 of the advertisement display apparatus. As stated before, the aperture usually has a diameter ranging between 1.0 mm and 1.5 mm although the-diameter can be varied within a range of between 0.5 mm and 5 mm. The ratio of the area occupied by the apertures to the area other than the apertures falls within a range of between 30:70 and 40:60. Front illumination lamps 18,18a and rear illumination lamps 19,19a are adapted to illuminate the front plate 3 and the rear plate 8, respectively, under the control of a light control device 20.
The rear plate 8 can be substituted by a thin rear advertisement display sheet adapted to be moved reciprocatingly by an electric motor 21 through the operation of driving rolls 9,10. Alternatively, it is possible to use, in place of the rear plate 8, an endless rear advertisement display sheet 17 constituted by a series of unit sheets carrying different display patterns, adapted to be driven in one direction by a drive roll 11, along guide rolls 12,13,14 and 15, as shown in Figure 13.
Figure 14 shows another arrangement which constitutes a different embodiment in which the rear plate 8 is replaceably attached to guide frames 16,16a attached to the rear side of the front plate 3.
If a timer (not shown) is incorporated in the circuit of the electric motor 21 mentioned above, it is possible to drive or move the rear plate or sheet intermittently by a predetermined distance.
Various forms of the rear plate or sheet explained above can apply also to the front plate. Namely, the front plate may be constructed in such a manner as to be able to move reciprocatingly, or may be formed as an endless sheet consisting of a plurality of unit sheets having different display patterns and adapted to be moved in one direction through a driving roll by an electric motor under the control of a timer. It is possible also to construct the front plate such that it can be replaceably fitted in a guide frame. By adopting such arrangements, it is possible to obtain various combinations of display patterns of the front and rear plates or sheet.
In the first embodiment of the invention having the described construction, as the front illumination lamps 18,18a are turned on; only the advertisement display pattern 2 on the front plate is illuminated and becomes clearly visible in the direction of arrow A in Figure 2, as illustrated in Figure 1. In contrast, if the front illumination lamps 18,18a are turned off while the rear illumination lamps 19,19a are put on, only the advertisement display pattern 7 on the inner surface of the rear plate 8 is distinguishably recognizable in the direction of arrow A through the apertures 5 of the front plate 3. Thus, when both of the front and rear illumination lamps 18,18a, 19,19a are put on simultaneously, both of the display patterns 2 and 7 are observed from the front side of the frame 4, as shown by arrow A, in a superimposed manner, although the superimposed patterns are not shown in the drawings.
Therefore, by controlling the brightness of the front and rear illumination lamps 18,18a, and 19,19a as desired and in relation to time, such that for example, lamps 18,18a of the front and rear illumination lamps 18,18a, 19,19a are gradually and linearly brightened while the other lamps 19,19a are gradually dimmed by a suitable light control means 20 (see Figure 2), while varying the combination between the advertisement display patterns on the front and rear plates, it is possible to obtain a plurality of advertisement patterns displayed on a single advertisement display apparatus in quite an easy and simple manner.
Figures 6 and 7 show a second embodiment of the invention in which, in place of the front plate 3 having a multiplicity of small apertures dispersed uniformly as used in the first embodiment, a front panel 28 having the following construction is used to form, in combination with the rear plate 8, the plate unit which is mounted at the central portion of the frame 4. Namely, the front plate 28 of this embodiment is made of a transparent material on the surface of which are formed a multiplicity of minute opaque spots or patches 26 , by opaque ink or the like material, uniformly at a constant pitch. In addition, the front plate 28 is provided thereon with an advertisement display pattern 27 such as letters, figures, signs or combinations thereof formed by printing. In this case, the ratio between opaque area and the transparent area generally ranges between 75:25 and 65:35.
In this operation, when the front illumination lamps 18,18a are turned on, only the advertisement display pattern 27 is illuminated and the light is reflected as shown by arrow 29, so that those who looks at the front side of the advertisement display apparatus see the display image as if it contains only the advertisement display pattern 27. Then, as the illumination lamps 19,19a are turned on while the lamps 18,18a are turned off, the light emitted from the lamps 19,19a passes through only the transparent portions of the outer surface of the rear plate and is interrupted by the advertisement display pattern 7 on the latter, as represented by an arrow 30. The advertisement display pattern 7, therefore, can be distinctively recognised from the front side of the advertisement display apparatus, i.e. in the direction of arrow A, as will be understood from Figure 8.
The size and shape of the opaque portion 26 of the front plate 28 can be selected as desired in accordance with the nature of the advertisement display pattern to be printed, to provide different ratios of area between the transparent portion and opaque portion, and to provide various forms such as rectangular form 31, linear form 32, staggered form 33, spiral form 34 and so forth, as shown in Figures 9 to 12.
Needless to say, various arrangements described before in connection with the construction of the rear plate 8 can directly apply to the front plate 28 of this embodiment, as in the case of the front plate 3 of the first embodiment.
The plate 28 having transparent and opaque portions formed on the surface of a transparent member is advantageous as compared with the plate 8 having small apertures formed in an opaque member in that it permits an easy selection of the forms of configurations of the transparent and opaque portions and permits an easy minute treatment.
Referring now to Figure 16, a front advertisement display plate 38 has a transparent plate member 35 on the outer surface of which printed is an advertisement pattern 36 consisting of letters, figures, signs or combinations thereof in such a manner as to leave blank transparent portions. In addition, a multiplicity of small opaque portions of regular size are printed on portions of the inner surface of the transparent plate member 35 other than the above-mentioned transparent portions, by means of an opaque ink or the like.
In some cases, the front advertisement display plate 38 may be formed by at first printing on the inner surface of the transparent plate member 35 the advertisement pattern 36 in such a manner as to leave transparent portions, printing a multiplicity of opaque portions 37 of a regular size on the portions other than the transparent portions by means of a white ink, and printing opaque portions by means of a black ink on the opaque portions formed by the white ink.
On the other hand, a rear advertisement display plate 41 has a milk white translucent plate material. An advertisement display 40 such as letters, figures, signs or combinations thereof is printed either on the inner side or outer side of the milk white translucent plate 39.
These front advertisement display plate 38 and the rear advertisement display plate 41 are assembled together to form a plate unit which is mounted, as shown in Figure 17, on the central part of a frame 44 having front illumination lamps 42,42a and rear illumination lamps 43,43a. It will be seen by those skilled in the art that this arrangement provides an advertisement display apparatus having a simple construction and capable of presenting a more beautiful and attractive advertisement display.
Thanks to the use of the milk white transparent plate member, the light from the lamps is suitably diffused and the lamps are concealed advantageously.
It is possible to use, as the material of the front plate 3, a sheet-like member which has black or other dark colour on one side and metallic aluminum colour on the other side. This material affords a more distinctive and beautiful presentation of advertisement display patterns because it reflects the light at a higher efficiency. Similarly, in the front plate 28 of the second embodiment, the opaque portion may be formed by an evaporation of aluminum. In such a case, the opaque portion exhibits a bright metallic lustre to increase the brightness of the display surface and, hence, the effect of the advertisement display.
As has been described, the advertisement display apparatus of the invention offers a great advantage in display of two or more kinds of advertisement display patterns by a single apparatus, over the conventional display apparatus.
