Description

The present invention relates to a lightweight mirror signage capable of arranging a display device behind a mirror and displaying an image of the display device on the surface of the mirror.

Mirror signage is a half mirror and a display device installed in the housing, and when the image is displayed on the display device placed behind the half mirror, the image of the display device is displayed on the surface of the half mirror used as a normal mirror. Is a device configured to display.

It can be said that it is a small information transmission device that follows the flow of digital signage, which is already used as an electronic signboard in large-scale street visions, stations, airports, shopping malls, and so on. In particular, by using a half mirror, the range of indoor use is expanded, and it is expected as a medium that can effectively transmit various information other than advertisements in various places.

The mirror signage (thin display device) described in Patent Document 1 uses a square frame for fixing the display device in an upright state as a housing. That is, the front surface of the square frame is closed with a half mirror, and a display device such as a liquid crystal display is installed on the back side of the half mirror. Further, the back surface of the square frame is closed with a black shielding board, and a liquid crystal display or the like is fixed to the central portion of the black shielding board with four hooks to form a display device.

Further, in order to arrange the display device vertically between the upper surface and the lower surface of the square frame, the height adjusting legs provided above and below the display device are fixed to the upper surface and the lower surface of the square frame in a stretched state. ing.

Japanese Patent No. 5232839

Since the mirror signage described in Patent Document 1 fixes the display device to the central portion of the black shielding board with four hooks, a metal plate or the like having excellent supporting strength is used for this black shielding board. Furthermore, in order to fix the display device in which the liquid crystal display etc. is fixed to the black shielding board in a stretched state on the upper surface and the lower surface of the square frame, this square frame is also inevitably made of a material such as a metal material having high supporting strength. Will be done.

As described above, in the conventional mirror signage, a large amount of metal material is often used for the housing and the like, and therefore, the weight of the entire mirror signage has to be extremely heavy. In particular, as the screen size of the display device increases, the weight of the housing also increases, so that there is a disadvantage that the installation location of the mirror signage is limited to a location having strength that can withstand the total weight of the display device and the housing.

On the other hand, even when this mirror signage is used indoors, for example, when it is used in a hall of a building or a station yard, the screen size of the display tends to be large. Moreover, the places where it is used are further diversified, and for example, mirror signage that can be used outdoors is desired.

Therefore, the present invention was created to solve the above-mentioned problems, and by reducing the weight of the housing that supports the half mirror, display device, etc., it is easy to install in various places that have been difficult to install in the past. The purpose is to provide a lightweight mirror signage.

In order to achieve the above object, the first means in the present invention is configured to display the image of the display device 20 arranged in the housing 10 on the surface of the mirror glass 30 arranged in the front surface of the display device 20. In the mirror signage, the housing 10 is formed of foamed styrol , and a connecting metal fitting 11 that is integrated in the housing 10 to reinforce the housing 10 is provided on the housing 10 and the back surface of the display device 20. It is provided so that it can be freely connected to the fixing metal fitting 40 for fixing.

In the second means, the housing 10 is formed of styrofoam obtained by firing raw particles having a particle size width of 0.6 to 1.2 mm 20 to 30 times, and the housing 10 is formed of the styrofoam. The surface of the housing 10 is cured by adhering a curing agent to the surface.

The connecting metal fitting 11 of the third means is provided integrally with the housing 10 at the time of foam molding of the housing 10, and a part or the whole of the connecting metal fitting 11 is embedded in the housing 10.

In the fourth means, the vertical frame body 14 and the horizontal frame body 15 forming the housing 10 are separately formed, and the vertical frame body 14 and the horizontal frame body 15 are connected to form a rectangular housing 10. is doing.

The fifth means is to project a locking portion 12 on the front surface side of the housing 10, lock the mirror glass 30 around the front surface of the mirror glass 30, and fix the fixing body 13 in the housing 10. The mirror glass 30 is configured to fix the back surface of the mirror glass 30.

By forming the housing 10 with a synthetic resin material as in claim 1, it is possible to provide an extremely lightweight mirror signage. As a result, conventionally, it is possible to eliminate the inconvenience that the installation location of the mirror signage is limited as the screen size of the display device 20 becomes larger. Moreover, since the design of the housing 10 can be changed extremely easily by using the synthetic resin material, it is possible to provide a mirror signage having excellent design, for example, by forming a frame-shaped housing 10.

Further, since the connecting metal fitting 11 for reinforcing the housing 10 and the fixing metal fitting 40 fixed to the back surface of the display device 20 are connected, the display device 20 can be reliably fixed in the housing 10.

As in claim 2, the housing 10 is formed of foamed styrene in which raw particles having a particle size width of 0.6 to 1.2 mm are fired 20 to 30 times, and the surface of the housing 10 is cured of a urethane resin. Since the housing 10 is cured by applying the agent, the strength of the housing 10 is ensured, and the display device 20 and the mirror glass 30 can be reliably fixed. As a result, it is possible to provide a housing 10 for extremely lightweight mirror signage.

Moreover, since the surface of the housing 10 is cured by the curing agent adhering to the surface, the weather resistance and water resistance of the housing 10 are improved, and the mirror signage can be installed outdoors.

As in claim 3, the connecting metal fitting 11 is provided integrally with the housing 10 at the time of foam molding of the housing 10, and a part or the whole of the connecting metal fitting 11 is embedded in the housing 10, so that the housing 10 made of synthetic resin is used. Support strength can be significantly increased.

As in claim 4, the vertical frame body 14 and the horizontal frame body 15 forming the housing 10 are separately formed, and the vertical frame body 14 and the horizontal frame body 15 are connected to form a rectangular housing 10. Therefore, it is possible to provide the housing 10 at an extremely low cost as compared with the integral molding of the housing 10, and there is also an effect of improving the transportation efficiency.

As in claim 5, since the front periphery of the mirror glass 30 is locked to the locking portion 12 of the housing 10 and fixed by the fixing body 13, the housing 10 has a function as a cushioning material for the mirror glass 30. The mirror glass 30 can be safely fixed. As a result, even if the mirror glass is installed in a station yard where there is a lot of vibration, the housing 10 can absorb the external vibration and prevent the mirror glass 30 from having an adverse effect.

The present invention is a mirror signage configured to display an image of a display device 20 arranged in a housing 10 on the surface of a mirror glass 30 arranged on the front surface of the display device 20 (see FIGS. 1 and 2). ..

In the present invention, the display device 20 is fixed by the fixing bracket 40 fixed to the back surface of the display device 20 and the housing 10 connected to the fixing bracket 40 (see FIG. 3).

The housing 10 is made of a synthetic resin material. That is, the housing 10 is formed of styrofoam obtained by firing raw particles having a particle size width of 0.6 to 1.2 mm 20 to 30 times. The housing 10 made of styrofoam foamed 20 to 30 times in this way is stiffer than normal styrofoam, and can increase bending strength and compressive strength.

Then, by applying a curing agent to the surface of the housing 10 formed of this special styrofoam to cure the surface, the compressive strength of the housing 10 can be further increased. Therefore, even if the surface of the housing 10 is pushed, it will not be easily dented, and the durability of the housing 10 can be ensured. In addition, the mirror glass 30 can be protected by the internal cushioning property. As the curing agent for Styrofoam, a curing agent made of urethane resin is mainly used.

The housing 10 is further provided with a connecting metal fitting 11, a locking portion 12, and a fixing body 13 (see FIG. 4).

The connecting metal fitting 11 is a member that reinforces the housing 10 and connects the housing 10 and the fixing metal fitting 40 (see FIGS. 4 and 5). The illustrated connecting metal fitting 11 is provided integrally with the housing 10 when the housing 10 is formed. The connecting metal fitting 11 is integrated with the housing 10 in a state where a part or the whole is embedded in the housing 10.

The illustrated connecting metal fitting 11 shows a connecting metal fitting 11 in which a strip-shaped plate is bent into an S-shaped cross section (see FIG. 4). The connecting metal fitting 11 is almost entirely embedded, and only the portion connected to the fixing metal fitting 40 is exposed from the housing 10. In the illustrated example, the connecting metal fitting 11 having a hole 11A formed in a part of the connecting metal fitting 11 is shown (see FIG. 4). When the connecting metal fitting 11 is embedded in the hole 11A together with the molding of the synthetic resin material, the synthetic resin material fills up to the hole 11A and firmly holds the connecting metal fitting 11. In particular, when Styrofoam, which is obtained by firing raw particles having a particle size width of 0.6 to 1.2 mm 20 to 30 times, integrates the connecting metal fitting 11 through the holes 11A, a strong housing 10 is formed.

Further, the shape of the connecting metal fitting 11 is not limited to the illustrated example, and can be arbitrarily changed by using the connecting metal fitting 11 such as an L-shaped side surface or an I shape to bury the whole or half part. can. Further, it is also possible to use the reinforcing metal fitting 17 to be overlapped with the surface of the housing 10 or the connecting metal fitting 11 together with the connecting metal fitting 11 embedded in the housing 10 (see FIG. 8 (b)).

The locking portion 12 is a portion bent and formed on the front surface side of the housing 10, and the periphery of the front surface of the mirror glass 30 is brought into contact with the inside of the locking portion 12 (see FIG. 4). On the other hand, the fixed body 13 is a member that abuts on the back surface of the mirror glass 30 locked to the locking portion 12 and fixes the mirror glass 30 in the housing 10.

For the fixed body 13, any material such as a metal material can be selected in addition to the rubber material. In the illustrated example, the fixed body 13 in which the fixed body 13 is adhered to the inner side surface of the housing 10 is shown, but the fixing means of the fixed body 13 can be arbitrarily changed (see FIG. 4).

Further, the housing 10 is configured by combining the vertical frame body 14 and the horizontal frame body 15. That is, these vertical frame bodies 14 and horizontal frame bodies 15 are formed separately, and by connecting them, a rectangular housing 10 is formed (see FIG. 6). Further, it is also possible to form various rectangular housings 10 by forming the vertical frame body 14 and the horizontal frame body 15 according to their sizes and selecting and connecting them.

In the illustrated example, the vertical frame body 14 and the horizontal frame body 15 are connected by a joint 16. The joint 16 has a structure in which a dovetail-shaped convex portion 16A and a concave portion 16B are formed and these are fitted together (see FIG. 7). Further, the means for connecting the vertical frame body 14 and the horizontal frame body 15 is not limited to the illustrated example, and can be arbitrarily changed by using other joint fittings or the like.

As the display device 20, a thin display device such as a liquid crystal display or a plasma display is selected. Then, the fixing bracket 40 is fixed to the back surface of the display device 20. In the illustrated example, the fixing nut 42 arranged on the display device 20 side and the fixing bolt 41 arranged on the fixing bracket 40 side are fixed by screwing (see FIGS. 2 and 3). Such fixing means of the display device 20 is not limited to the illustrated example.

As the mirror glass 30, a half mirror for mirror signage is used (see FIG. 2). In the illustrated example, a mirror glass 30 having a shatterproof film 31 attached to the back surface is used (see FIG. 4). By using such a mirror glass 30, even if the mirror glass 30 is damaged, the fragments do not scatter, so that the safety at the time of use can be improved.

The fixing bracket 40 is a bracket that is fixed to the back surface of the display device 20 (see FIG. 2), and the fixing bracket 40 is connected to the connecting bracket 11 of the housing 10 (see FIG. 8). In the illustrated example, the rectangular fixing bracket 40 is connected to the facing connecting bracket 11 of the housing 10 (see (a) to (c) of the same figure). At this time, in the figure (d), the deformed fixing metal fitting 40 is connected to each connecting metal fitting 11 of the housing 10. In this way, the connection between the fixing metal fitting 40 and the connecting metal fitting 11 can be arbitrarily changed according to the intended use.

Further, FIG. 8B shows a substantially L-shaped reinforcing metal fitting 17 that connects the connecting metal fittings 11 of the housing 10 to each other. With the reinforcing metal fitting 17, it is possible to further increase the connecting strength between the connecting metal fitting 11 and the fixing metal fitting 40.

The configuration of the present invention is not limited to the illustrated examples, and the design can be freely changed without changing the gist of the present invention.
