Description

Detailed explanation of the device

The present invention relates to a character-type sign display represented by three-dimensional characters.

Conventional signboards have been expressed by drawing characters and patterns on a flat surface, but as a more effective expression method, so-called box characters, three-dimensional characters or channel characters with the character part protruding from the wall surface or flat signboard part The so-called sign display has come to be adopted.

At night, a neon sign method can be considered as an advertising medium that is easily visible, but since neon signs are expensive to manufacture and require troublesome maintenance, internally illuminated channel characters can be used instead. There are many cases.

The internally illuminated channel letters have a built-in light source such as an LED and are lit. In that case, the material of the channel letters is made of metal such as steel, aluminum, stainless steel, brass, copper, and zinc except for the light transmitting surface. Mostly there is.
These metal products can also be given a high-class surface finish such as urethane coating, sheet pasting, and gold plating, and the metal internally illuminated channel letters are robust and highly workable, but they are latent in terms of weight and cost. Demand for improvement.

As a conventional channel character, a three-dimensional character-shaped light emission having a housing made of a metal member such as stainless steel or an alloy with a translucent resin used for the front light emitting surface plate and a glossy white coating on the inner surface. There is an advertising device. (Patent Document 1)

In the advertising device here, a means of fixing the light-emitting surface plate to the side surface portion via the light-transmitting support plate is adopted, and the light-transmitting support plate is formed to be thinner than 1/4 of the thickness of the light-emitting surface plate. With a structure that gives elasticity, the adhesive surface has the minimum necessary area, and fixing with only the light-transmitting support plate does not prevent the light-emitting surface plate from falling off. It plays an auxiliary role in preventing falling off for the structure in which the edges mesh precisely, but special equipment and advanced processing technology are required to manufacture the structure in which the edges mesh precisely.

Further, in order to fix the light emitting surface plate such as acrylic and the metal housing, the shadow of the screw entering from the lateral direction is vertically adhered to the back surface of the light emitting front plate as a means for preventing the light design from being hindered. If a light-transmitting support plate is used and different materials of metal and resin expand and contract in the same direction at different ratios, the light-transmitting support plate fixed in the vertical direction always has an inherent risk of breakage. .. In order to avoid this, it depends on precise meshing.

As a method of fixing the light emitting surface plate and the side plate (housing) of the channel characters, such a support member is not used, and as a method of fixing between the members, the fixed portion area is large and uniform, and the fixing strength is ensured. It is desirable to use easy-to-adhere, and it is easy to adhere and the processing time can be significantly shortened.

Patent No. 6163271

When it is required to reduce the weight and cost of the internally illuminated channel characters, or to have a detailed design, the internally illuminated channel characters will be manufactured from a resin material such as plastic. In order to ensure the same ease of construction and maintainability as the type channel characters, it is necessary to mold the surface material, which incurs the initial cost of creating wooden molds and molds, which reduces the manufacturing cost per product. For this purpose, mass production is required, and as a sign display in which the dimensions and the like are often designed individually according to the installation environment, the adoption conditions are limited to the façade sign of a chain store.

Even materials other than metal do not require molding, and especially when new building materials are used to reduce the burden on the environment, the appearance and ease of construction equivalent to those of metal internally illuminated channel letters are ensured. In addition, it is required to provide internally illuminated channel characters that can maintain the light source.

The present invention aims to reduce the manufacturing process and cost by creating a channel character structure consisting of a front plate, a side plate, and a bottom plate using a two-dimensional cutout material of plastic resin, and further small-quantity production and detailed design. As a material that enables the property, a channel character structure that does not use a metal and does not require a molding process is provided.

When the internally illuminated channel characters are emitted from the front, the purpose is to make the character shape emit light clearly. Therefore, the front plate of the light emitting portion uses a transmissive diffusive resin material such as acrylic milk half-color cut out into the character shape.

Internally illuminated channel characters A certain separation distance is required between the light source installation part such as the built-in LED and the front plate to make the front of the character emit light evenly, and to secure the separation distance from the bottom plate as the light source fixing place. A side plate is required, and the shape naturally becomes a box-shaped three-dimensional shape, which is also the reason why the channel character is generally called a box character.

When fixing the front plate of the light emitting portion to the box-shaped characters, it is necessary to fix the front plate from the side plate so as not to obstruct the shape of the light emitting characters. Further, when fixing the internally illuminated channel characters to the outer wall or the like, it is necessary to fix the bottom plate to the outer wall or the like before fixing the front plate in advance.

Generally, in order to install an internally illuminated channel character, it is necessary to provide a fixing and detaching part on the character side plate, but as a manufacturing method, welding or bending is performed for metal, and resin is used for plastic resin. It is manufactured by three-dimensional processing such as molding into a shape having a side plate portion in advance by molding. Another method is to cut out the side plate by cutting, but the material that can be easily cut cannot guarantee the fixing strength and is not feasible.

Since the channel character in the present invention is composed of a front plate, a side plate, and a bottom plate using a two-dimensional cutout material of plastic resin, a three-dimensional molding process is not required, and a detailed design can be produced in a small amount. It is possible to have a property and reduce the manufacturing cost.
Further, the structure of the present invention has a high degree of freedom in selecting the material of the side plate, and it is easy to set the material and dimensions in consideration of the screw fixing strength with the bottom plate in advance.
From the viewpoint of the optical design, the detachable screw 7 for fixing the housing of the channel character enters the side plate 3 from the bottom plate 4 in the vertical direction, so that the optical design of the light emitting surface plate 2 is not hindered.

It is the structural exploded view which showed each part of this invention in the cross section. It is a figure which shows the example of the light source arrangement on the bottom plate and the side plate in the inside of this invention.

FIG. 1 shows a perspective exploded view of the channel character structure of the present invention.
In the process of manufacturing the channel character structure, the light emitting surface plate 2 is adhered to the side plate 3 cut out in the character shape. The front holding edge 1 is adhered in order to hide the adhesive surface of the side plate 3 and the light emitting surface plate 2 and to secure the aesthetic appearance. The front holding edge 1, the light emitting surface plate 2 and the side plate 3 are adhered with an adhesive whose strength is guaranteed. It is possible to make the adhesive surface inconspicuous by adjusting the transparency by selecting the color of the light emitting surface plate 2, and in that case, the design does not use the front pressing edge 1. The side plate 3 may be any material that is easy to process, such as a polystyrene resin board or laminated lumber, and is more preferably a recycled material or the like in consideration of reducing the environmental load.

FIG. 2 shows a front view of the main parts of the present invention. FIG. 3 shows an exploded view of each part of the present invention represented by a cross section. Explaining the configuration of the present invention with reference to these, in order to improve durability, a ventilation hole 8 for releasing heat generated from a light source is provided in advance in the bottom plate 4. A guide hole for the detachable screw 7 is appropriately provided in the bottom plate 4 at a necessary place. The bottom plate 4 and the side plate 3 are attached by a detachable screw 7 that is rubbed in one direction of the front holding edge. Since the side plate 3 has a thickness corresponding to the distance from the light source, it is easy to secure sufficient screw fixing strength.

The channel character body is attached to a wall surface or the like by the installation guide plate 5. The bottom plate 4 is attached to a wall surface or the like in advance with screws 9. The installation portion guide plate 5 and the bottom plate 4 are provided with an L-shaped angle 6 that can be attached and detached in advance, and the position where the L-shaped angle 6 is provided may be arbitrary depending on the installation situation of the channel character, such as up, down, left, and right. Knead the screw 10 into the L-shaped angle 6 from the horizontal direction of the channel character, and attach the channel character to the wall surface or the like. The configuration of the installation guide plate 5, the L-shaped angle 6 and the screw 10 makes it possible to attach and detach the channel character without damaging the surface such as the wall surface.

As shown in FIG. 4, an example of arranging the LED 11 on the bottom plate 4 and an example of arranging the light source on the side plate 3 inside the present invention are provided in the bottom plate 4 with a plurality of LED 11s as light sources. By adopting the detachable screw 7, maintenance of the light source built in the channel character becomes easy. Further, the built-in light source 11 may be installed on the bottom plate 4 or on the inner side surface of the side plate 3. When the light source 11 is arranged on the bottom surface 4 and the side plate 3 uses a transmissive diffusive resin material such as acrylic milk half color similar to the light emitting surface plate 2, light can be emitted from the front and side surfaces. can.

The shape of the installation guide plate 5 is changed according to the shape and structure of the other party to which the channel character structure is attached. In some cases, only the L-shaped angle 6 may be installed, and an appropriate installation means may be adopted. It is possible.
