[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a power supply type panel, and more particularly, to a power supply type panel in which the panel body consumes the electric power to perform some operation by supplying power to the panel body.

[0002]

[Prior Art]

 Conventionally, this type of power supply type panel has been designed to change the voltage applied to the liquid crystal layer by switching the voltage applied to the liquid crystal layer on and off to accelerate the phase change of the liquid crystal layer and switch the panel body between transparent and opaque. A liquid crystal panel was known in which the transparency was changed. In addition, a heat-generating panel was also known in which the frozen water on the surface of the panel body was thawed by supplying power to the heating wire.

In these conventional power feeding type panels, as a power feeding method for power consuming members such as a liquid crystal layer and a heating wire, a terminal is provided in the panel body, an electric cord is connected to the terminal, and a tip of the electric cord is connected. A method has been adopted in which a connector such as a plug is provided and the connector is connected to a mating connector such as an outlet provided on the wall surface of the house.

[0004]

[Problems to be solved by the device]

 However, in order to use a conventional power supply type panel, such as a liquid crystal panel, for a window or a blind of a house, the panel main body where the collector electrode is exposed is surrounded by an edge frame to form a panel unit, which is used as a window. When installed, if the outlet is installed at a location far away from the terminals, such as on the side opposite to the terminal installation position on the panel body, when you connect the plug by inserting it into the outlet, use a long distance to connect the electrical cord. There was a problem that the electric cords were messed up around and became unsightly, and the electric cords that were routed were a hindrance. In order to avoid such a situation, an electric wire cover may be installed on the floor or wall surface, and an electric cord may be routed through the electric wire cover. However, this would require extra work to install the electric wire cover. There is a problem that becomes. Furthermore, the liquid crystal panel has a problem that it cannot meet market needs because it requires processes such as collecting electrode processing and connecting terminal installation.

The present invention has been made in view of the above problems. Not only can the electric cord be neatly routed along the edge of the panel body, but also the electrical cord that is routed cannot be seen from the outside. It is an object of the present invention to provide a power-supply-type panel that can be turned on and that can pull out an electric cord from a place closest to an outlet or the like.

[0006]

[Means for Solving the Problems]

 In the power-feeding panel of the present invention, the inside of the edge frame provided around the power-feeding panel body is a space for routing the electric cord connected to the terminal of the panel body along the edge of the panel body. It is formed in.

[0007]

[Action]

 With this configuration, the electric cord can be drawn out from a desired portion around the panel body by drawing the electric cord around the inner space of the edge frame. In addition, if the inner frame is formed with a hollow frame, the electric cord drawn in the inner space cannot be seen from outside. Further, in the liquid crystal panel, the collector electrode exposed in the peripheral portion is protected by the edge frame.

 1 is an exploded perspective view schematically showing a power feeding type panel A according to an embodiment of the present invention, FIG. 2 is a front view of the power feeding type panel A, FIG. 3 is an enlarged sectional view of a portion X of FIG. 2, and FIG. 2 is an enlarged sectional view of the Y portion, and FIG. 5 is an enlarged sectional view taken along the line ZZ of FIG.

In FIG. 1, reference numeral 1 is a power supply type panel body. The panel body 1 includes a liquid crystal panel, which will be described later, or a heat generating panel described at the beginning. That is, as the panel main body 1, a panel is selected in which the panel main body consumes the electric power to perform some operation by supplying power. The panel body 1 has terminals 2 and 2 exposed at its end faces, for example, and an electric cord 3 is connected to the terminals 2 and 2, and a plug 4 is provided at the tip of the electric cord 3. The terminals 2 and 2 may be of the non-exposed type such that they are embedded in the panel body 1.

Reference numeral 5 is an edge frame made of synthetic resin. The edge frame 5 is divided so as to correspond to the four sides of the rectangular panel body 1, and each of the divided edge frames 5 has an H-shaped edge frame body 51 and a cover 52. Consists of. As shown in FIGS. 2 to 5, in the edge frame main body 51, a U-shaped fitting portion 54 that protrudes inward from the partition plate portion 53 is fitted into the end edge of the panel main body 1 and is removed from the partition plate portion 53. The cover 52 is fitted into the U-shaped projecting portion 55 projecting toward one side, and the portion surrounded by the projecting portion 55 and the cover 52 becomes a space 56 for routing the electric cord 3. The tip portion 59 of the fitting portion 54 has a spring characteristic, and the spring characteristic of the tip portion 59 can absorb variations in the thickness of the panel body 1.

In the edge frames 5 mounted on the respective sides of the panel body 1, the fitting portions 54, 54, the partition plate portions 53, 53, and the protrusions 55, 55 are provided at the corners of the panel body 1. The spaces 56 of the edge frames 5 ... Are communicated with each other by abutting each other. At the portion where the electric cord 3 is introduced into the space 56, an opening 57 is formed in the partition plate portion 53 of the edge frame main body 51 as shown in FIG. In addition, as shown in FIG. 4, an opening 58 is formed in the cover 52 at the portion where the electric cord 3 is pulled out from the space 56. The openings 57 and 58 are opened at desired locations as needed.

With the above configuration, the edge frame 5 is provided around the panel body 1, the opening 57 is opened in the partition plate portion 53 of the edge frame body 51, and the electric cord 3 is introduced into the space 56 through the opening 57. Then, the electric cord 3 is routed through the space 56 along the edge of the panel main body 1 to a desired position, and an opening 58 is opened at a predetermined position of the partition plate portion 53 of the edge frame main body 51, and the electric cord 3 is opened from the opening 58. It is possible to pull out three. For this reason, the electric cord 3 can be pulled out at the location closest to the outlet (not shown) on the power supply side. Further, since the electric cord 3 which is routed in the space 56 is covered with the edge frame 5 and cannot be seen from the outside, there is no room for the electric cord 3 to be noticeably unsightly.

Although the hollow edge frame 5 is formed by the edge frame main body 51 and the cover 52 in this embodiment, the configuration of the edge frame 5 is not limited to this. For example, the cover 52 may be omitted, and the edge frame body 51 may be configured by only the edge frame body 51, and the inner space of the protrusion 55 in the edge frame body 51 may be a space for routing the electric cord 3. .. Furthermore, the internal space of the above-mentioned projecting portion, which is formed in a U-shaped cross section that is open at the side surface, may be used as a space for routing the electric cord 3. As shown in FIG. 5, when a space is created between the fitting portion 54 and the panel body 1, the space 9 is filled with a filler 9 such as a caulking agent and sealed to prevent leakage of electricity due to infiltration of water or the like. It is desirable to prevent this.

FIG. 6 shows a modified example of the edge frame 5. In the edge frame 5, the edge frame main body 51 is divided into two by the partition plate portion 53, and the partition plate portion 53a of one of the split members 51a is provided with the protruding piece 60 having the engaging projection 61. The partition plate portion 53b of the other split member 51b is provided with a sawtooth-shaped multistage engaging portion 62 as shown in detail in FIG. Then, the projecting piece 60 is pushed into the multi-stage engaging portion 62 to engage the engaging protrusion 61 with a predetermined position of the multi-stage engaging portion 62, thereby integrating the two split members 51a and 51b and integrating them. The surrounding portion of the panel body 1 is sandwiched by the fitting portion 54 of the edge frame 5 that has been cut. Further, the cover 52 and the projecting portion 55 of the edge frame 5 are engaged with each other via a concave-convex fitting 64.

According to the edge frame 5 of this configuration, in the mounting portion of the cover 52 in the edge frame body 51, the edge frame body 51 is opened by the cover 52 fitted to the protrusion 55 as shown by an arrow M. In order to receive the force in the direction, a force in the closing direction is applied to the tip end portion of the fitting portion 54, as indicated by an arrow N, with the vicinity of the roots of the partition plate portions 53a and 53b as a fulcrum. Therefore, there is an advantage that the tips 54a, 54a of the fitting portion 54 are strongly pressed against the outer surface or the inner surface of the panel body 1 to help improve the watertightness. When the tip portions 54a and 54a of the fitting portion 54 are formed of a soft resin layer by molding the divided members 51a and 51b by a two-layer extrusion method, the watertightness is improved by one layer. In this way, if the watertightness between the tip end portions 54a, 54a of the projecting portions 54 of the edge frame 5 and the surface of the panel body 1 is increased, the edge frame is not used when the power feeding type panel is used for a window of a house. 5 has an advantage that the inconvenience of water infiltrating and accumulating in the inside of 5 does not easily occur, and in a power-supply-type panel using a liquid crystal panel described later, there is an advantage of helping to prevent a short circuit of an electric circuit part in advance. is there. The same advantage is exhibited by increasing the watertightness of the mounting portion between the frame body 51 and the cover 52.

FIG. 8 illustrates the panel body 1 used for the liquid crystal panel described at the beginning. In this panel body 1, a transparent laminate 72 made up of a transparent electrode 73 and a resin film 74 made of a transparent resin sheet such as polyethylene terephthalate (PET) is superposed on both sides of a liquid crystal layer 71 to form a liquid crystal. A sheet 76 is formed, transparent outer plates 75, 75 made of polycarbonate resin, glass, or the like are superposed on the outer side of the sheet 76, and terminals 2, 2 as collector electrodes are embedded in a sealing agent 78. .. Reference numeral 77 denotes an adhesive or an adhesive, which is used to connect the liquid crystal sheet 76 and the outer plate 75. However, this adhesive or adhesive 77 is not indispensable as long as the liquid crystal shield 76 and the outer plate 75 can be held by an edge frame (not shown).

According to the power feeding type panel A using such a liquid crystal panel as the panel body 1, when the voltage is applied to the liquid crystal sheet 76, the panel body 1 becomes transparent, and when the voltage application to the liquid crystal sheet 76 is stopped, the panel body is 1 becomes opaque. In addition, the transparency of the panel body 1 changes according to the applied voltage. It should be noted that the outer plate 75 of the panel body 1 may be provided with characters or patterns.

9 and 10 show another embodiment. In this embodiment, the liquid crystal sheet 76 is divided and arranged. In this case, an excellent blind effect can be obtained by controlling each of the liquid crystal sheets 76 so that they are alternately turned on and off. When such a control method is adopted, the electric wiring may be complicated, but even in that case, it is convenient to store the electric wiring in the space 56. In addition, 79 is an insulation separation zone.

The power-supply-type panel A, particularly the liquid crystal panel described above, can be used not only as the window glass of a house itself but also by being installed on an existing window glass so that the liquid crystal sheet can be transparent and opaque depending on the voltage on / off. Since it can be provided with a function as a blind that switches to and, it can be suitably used as an auxiliary window glass or as a partition for partitioning the room. Further, the above-mentioned heat generating panel can be used as a panel for defrosting window glass of a house or as a panel for defrosting automobile glass.
