Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to an indoor advertising light that uses a light source to display various guides, displays, instructions, or decorative patterns inside a building or room.

Conventional technology When a light source is placed on the edge of an acrylic resin plate (acrylic plate) or glass plate, which has smooth front and back surfaces, no light leaks in the direction perpendicular to the plate surface, and the plate appears transparent; It has the characteristic that the end surface appears shiny.
This is due to the difference in the refractive index for light between acrylic and glass and air, but when letters or illustrations are engraved or printed on the surface of such a light-guiding transparent plate, light is scattered in this area. , the text and illustrations stand out vividly, making it a highly expressive advertising medium.

Conventionally, the end of such a light-guiding transparent plate was inserted into the case containing the light source and fixed from the outside with screws, so the screws were conspicuous when used for everyday use such as on a tabletop, and when used indoors. The design of the advertising light was damaged. In addition, since the case houses lighting devices such as fluorescent tubes, glow lamps, and ballasts as light sources, it is necessary to be able to easily inspect these, but this point has traditionally been neglected, and during inspection, It was very troublesome to remove the bottom plate screwed to the case body, or to remove the case body from a fixed part such as a wall or ceiling.

Problems to be solved by the invention: To provide an indoor advertising light with a structure in which the attachment point of the light-guiding transparent plate is not visible from the outside, and the interior of the case can be inspected and the light source (fluorescent tube) replaced easily. The task is to

Means to solve the problem: A fixed side wall is erected on one side of the board to form the case body, and on the other side of the board, an opening/closing side wall with an opposite upper edge is pivoted so that its lower edge can be rotated and fixed. The edge of the light-guiding transparent plate is fixed to the upper edge of the fixed side wall, and the opposing upper edge of the opening/closing side wall is positioned at a position that hides the fixed part of the light-guiding transparent plate. The structure is such that the light source and lighting device are placed inside the case.

Function The pivotable and lockable opening/closing side walls facilitate inspection of the interior of the case.

The opposing upper edges of the opening/closing side walls hide the portion of the light-guiding transparent plate that is fixed to the fixed side wall.

Embodiment In FIG. 2, an indoor advertising light 1 has a case 2, left and right caps 3, 4 closing both sides of the case 2, and a hardened acrylic plate 5 as a light-guiding transparent plate. Letters and illustrations 6 are engraved on the smooth surface by silk printing or engraving. In addition, this text and illustration 6 are
Usually, it is formed so as to be sandwiched between the back surface of the acrylic plate 5 or the opposing surfaces of two acrylic plates. Further, inside the case, a light source 7 and a lighting device 8 are arranged, which will be described later.

As shown in FIG. 1, the case 2 consists of a case body 9 and an opening/closing side wall 10. The case body 9 is
The opening/closing side wall 10 is composed of a base plate 11 and a fixed side wall 12 erected integrally from one side of the base plate 11 . It is fitted and pivotally supported by a bearing 15 formed on the other side. The case body 9 and the opening/closing side walls 10 are both made of extruded aluminum.

The edge 16 of the acrylic plate 5 is fixed to the upper edge 22 of the stationary side wall with screws 17.

As shown in FIG. 3, the case body 9 and the opening/closing side wall 10 have an L-shaped fitting 1 on a base plate 11 on the side of the case body 9.
a ball catch receiver 19 fixed via 8;
Ball catch body 2 fixed to the opening/closing side wall 10 side
The ball catch mechanism 21 consisting of 0 can be fixed from a rotating state. When the opening/closing side wall 10 is fixed by the ball catch mechanism 21, the opening/closing side wall 10 is closed and the upper opposing edge 13 holds the fixing portion (screws 17) that fixed the acrylic plate 5 to the fixed side wall 12. , hide.

The left and right caps 3 and 4 are cast aluminum or synthetic resin molded products.

With reference to FIGS. 1, 3, and 4, the case 2, the light source 7 disposed therein, and the illumination device 8 therefor will be described in detail.

A ballast 23 and a glow lamp 24 are fixed to the center of the substrate 11 via washers and mounting screws, forming the lighting device 8. A cord 25 with a plug is connected to the lighting device 8, as shown in FIG. 1, which is drawn in from the outside through a hole with a bush provided in the fixed side wall 12.

On the inside of the fixed side wall 12, an upper edge groove 26 and an intermediate groove 27 are formed in the longitudinal direction, and an acrylic pusher 28 made of neoprene sponge is fitted into the upper edge groove 26 over the entire length of the groove. L-shaped socket fittings 29 are attached to the outer surfaces of both ends of the socket, and are fixed with screws via a back plate 30 fitted inside the intermediate groove 27. A socket 31 is fixed onto the socket fittings 29 fixed to both ends inside the case 2 in this way, and a fluorescent tube 32 serving as a light source is mounted between both sockets 31,31.

At the center of the base plate 11 on the opening/closing side wall 10 side, the L-shaped fitting 18 to which the ball catch receiver 19 is fixed as described above is fixed with screws.

Similarly to the fixed side wall 12, the opening/closing side wall 10 has an upper edge groove 33 formed inside the upper edge 13 and an intermediate groove 34 in the middle. 34 is fitted. And this intermediate groove 34
A ball catch body mounting back plate 35 is fitted into the ball catch body, and the ball catch body 20 is fixed to the center portion through this.

After attaching and arranging each part to the case in this way, first fix the acrylic plate 5 to the upper edge of the fixed side wall of the case body 9 as shown in FIG. 4 is fitted and screwed to the board 11, and then the shaft 14 at the lower edge of the opening/closing side wall 10 is rotatably fitted into the bearing 15 of the board 11.

As shown in Figure 5, the indoor advertising lights configured as described above are of the tabletop type (i), the message board type (b) using a stand, the type (c) that is directly attached to a wall or pillar, the protruding type (i) that uses a bracket, or the ceiling type. It can be made into types such as direct-mounted type, ceiling-mounted type, etc.
It is optional to form an advertisement on one side or both sides, and to select various sizes of the acrylic board depending on the content of the advertisement or decoration. However, if the size is large, use a powerful light source other than fluorescent tubes. Further, the fixing device for fixing the edge of the acrylic plate to the upper edge of the fixed side wall is not limited to the screws mentioned above, but various means and fixing devices such as adhesives and other fixing devices can be used, and the opening/closing side wall can be rotated freely. The structure is also not limited to that of the embodiment.

Note that in the description of this specification, directional terms such as upper edge and lower edge are used, but these terms are for convenience of explanation and may not always be literal depending on how the indoor advertising light is installed.

Effects Since one of the side walls making up the case is made into an opening/closing side wall that can be rotated and fixed, it is extremely easy to inspect the inside of the case and replace light sources such as fluorescent tubes.

If the opening/closing side wall is fixed to the case body using a ball catch mechanism as in the embodiment, the opening/closing operation can be performed with a single touch.
