Description

Title: THE CHANNEL SIGN BOARD

Technical Field

The present invention relates to a channel signboard, and more

particularly, to a channel signboard including an upper plate and a bottom plate

which are fastened to each other by a lateral fastener made of light transmissive

synthetic resin, in which the lateral fastener and the upper plate are attached by

an adhesive, and the lateral fastener and the bottom plate are engaged to each

other by a magnetic force or a fastening screw, without using a lateral frame

structure, so as to reduce a manufacturing cost of the channel signboard and

also increasing the productivity of the channel signboard, and in which the light

transmits the lateral fastener to increase an advertisement effect in night.

Background Art

Generally, a channel signboard is formed in characters or patterns, and

is attached to a wall in three dimensions. The channel signboard is formed in

a box type so that lighting equipment, such as a neon lamp or incandescent

lamp, is installed therein.

A conventional channel signboard will now be described with reference

to FIGs. 1 and 2. FIG. 1 is a perspective view illustrating a conventional channel

signboard, and FIG. 2 is an exploded perspective view illustrating a

conventional channel signboard.

A conventional channel signboard 10 includes an opened channel 20

formed on a side of the signboard and a cover 30 formed on an upper surface

of the signboard. The channel 20 includes a bottom plate 21 made of a metal

plate, such as stainless steel or aluminum, and a lateral frame 25 made of the

same metal plate as that of the bottom plate and attached to the bottom plate

21. The cover 30 consists of an upper plate 32 made of a synthetic resin and a

fastener 35 adhered to an edge of the upper plate. The cover 30 is fastened to

the upper portion of the opened channel 20.

The fastener 35 is made of a plastic material or a metal such as

aluminum.

The method of manufacturing the conventional channel signboard using

the plastic fastener or the aluminum fastener will now be described.

FIG. 3 is a cross-sectional view illustrating a process of manufacturing

the conventional channel signboard using the plastic fastener, and FIG. 4 is a

cross-sectional view illustrating a process of manufacturing the conventional

channel signboard using the aluminum fastener.

Referring to FIG. 3, a plastic fastener 35a includes a vertical fastening member 36a and an arrow-head type locking boss 37a integrally formed on an

upper end of the vertical fastening member 36a.

An adhesive 13 is applied to the contact surface between the edge of

the upper plate 32 which is formed in a character or pattern, and the locking

boss 37a of the plastic fastener 35a, and the locking boss 37a is adhered to the

upper plate 32 to form the cover 30. After the cover is laid on the upper portion

of the channel 20 having the same character or pattern as that of the upper

plate 32, the vertical fastening member 36a of the plastic fastener 35a is

fastened to the lateral frame 25 of the channel 20 by means of a fastening

screw 12, thereby completing the channel signboard 10. At that time, a lighting

equipment 22 is installed on the bottom plate 21 of the channel 20.

Referring to FIG. 4, an aluminum fastener 35b includes a vertical

fastening member 36a and a round type locking boss 37b integrally formed on

an upper end of the vertical fastening member 36a. A plastic clamping

member 38 is attached to the locking boss 37b.

An adhesive 13 is applied to the contact surface between the edge of

the upper plate 32 which is formed in a character or pattern, and the plastic

clamping member 38 attached to the locking boss 37b of the metal fastener

35b, and the clamping member 38 is adhered to the upper plate 32 to form the

cover 30. After the cover 30 is laid on the upper portion of the channel 20 having the same character or pattern as that of the upper plate 32, the vertical

fastening member 36a of the metal fastener 35b is fastened to the lateral frame

25 of the channel 20 by means of a fastening screw 12, thereby completing the

channel signboard 10. At that time, a lighting equipment 22 is installed on the

bottom plate 21 of the channel 20.

With the conventional channel signboard, the method of fastening the

channel and the bottom plate is varied depending upon the material and

construction of the channel and bottom, which will be described with reference

to the drawings.

FIGs. 5 to 7 are cross-sectional views illustrating the method of

fastening the channel and the bottom plate according to the material and

construction thereof.

The bottom plates 21a, 21b, and 21c cut in the same character or

pattern as that of the upper plate 32 (see FIGs. 3 and 4) are attached to the

lateral frames 25a, 25b, and 25c having the same as that of the bottom plates to

form the channel 20. The lighting equipment 22 is installed on the bottom

plates 21a, 21b, and 21c of the channel 20.

With the construction, the channel 20 is formed by welding the bottom

metal plate 21 onto the lateral metal plate 21c, as shown in FIG. 4a, while the

channel 20 is formed by engaging the bottom aluminum plate 21b with the lateral aluminum frame 25b by using a steel pin 23, as shown in FIG. 6. Also,

the channel 20 is formed by fastening the bottom metal plate 21c of steel or

aluminum to the bent portion of the lateral metal frame 25c of the same material

as that of the bottom plate by using the fastening screw 24.

The conventional channel signboard has the following drawbacks.

First, in case the lateral frame protruding from the bottom plate is made

of a metal material, it is difficult to handle the channel signboard due to its

heavy weight. Also, the welding operation lowers the workability.

Second, in case the lateral frame protruding from the bottom plate is

made of aluminum, the channel signboard is expensive. The engagement of

the steel pin by using a press requires for the intensive labor of an operator.

Third, the lateral frame protruding from the bottom plate is made of

aluminum or steel and the fastening is carried out through the bent portion, the

formation of the bent portion requires for the prolong operation time.

Last, since the lateral frame of the above channel signboard is made of

an opaque material and is extended from the bottom plate to the upper plate,

the light emitted from the lighting equipment cannot transmit the lateral frame.

Therefore, the advertisement effect is reduced in night. That is, the light

emitted from the lighting equipment transmits only the front surface through the

upper plate, and does not transmit the lateral portion. The conventional channel signboard can not be recognized when viewing at a side, but is

recognized only when viewing at front side.

addition, the oval boss 132a formed on the lower end of the vertical body 132

comes in close contact with the lower portion of the vertical plate 112 of the

bottom plate coupler 110 to increase the fastening force thereof. That is, the

contact force acts between the sliding prevention portion 139 and the right

upper surface of the vertical plate 112, and the contact force acts between the

oval boss 132a and the left lower surface of the vertical plate 112, thereby

increasing the fastening force thereof.

Also, the oval boss 132a is formed to have a thickness thicker than that

of the vertical body 132 so as to increase the strength of the lower end of the

vertical body 132.

The features of the assembled channel signboard according an

horizontal plate. A magnet 138 is fixed to the lower end of the vertical body

132, and is magnetically coupled to the steel horizontal bottom plate 121. In

this instance, the magnet 138 may be formed through injection molding when

the lateral fastener 130 is formed. Also, the magnet 138 may be inserted into

the receiving groove formed on the lower end of the lateral fastener 130.

The process of assembling the channel signboard according to another

embodiment of the present invention will now be described with reference to

FIGs. 15 and 16.

Both ends of the upper cover plate 32 having a predetermined

character or pattern are inserted between the upper support portion 135 and the

lower support portion 137 which are integrally formed on the upper portion of

the vertical body 132 of the lateral fastener 130. The adhesive 13 is applied on

outer surface of the horizontal bottom plate 121 , As a result, the magnet 138

provided on the lower end of the vertical body 132 is magnetically coupled to

the steel horizontal bottom plate 121.

The channel signboard according to another embodiment of the present

invention is completed by the above assembling process. In this instance, the

lighting equipment 22, such as neon lamp or incandescent lamp, is installed on

the horizontal bottom plate 121 of the channel signboard.

The features of the assembled channel signboard according another

embodiment of the present invention will now be described.

First, since the channel signboard of the present invention does not use

a lateral frame of a bottom metal plate formed on a conventional channel

signboard, the total weight of the channel signboard can be reduced, and the

Second, since the lateral plastic fastener is provided in place of the

lateral metal frame, the light emitted from the lighting equipment can transmit

advertisement effect in night.

Third, the lateral fastener is fastened to the horizontal bottom plate by

means of the magnet, without using a fastening screw, thereby improving the

workability and shortening a working time.

In the channel board having the above features according to another

embodiment of the present invention, there is a limitation in that the horizontal

bottom plate should be made of a metal plate in order to utilize the magnetic

force of the magnet. That is, in case the horizontal bottom plate is made of

aluminum, the magnet cannot be used. In this instance, the strip of magnet is

replaced with an aluminum plate, and the lateral fastener may be fastened to

the bottom plate by using a fastening screw. Of course, this case may have

the above first and second features.

A similar case will be described with reference to an alternative

embodiment.

FIG. 17 is a perspective view illustrating the assembled state of a

channel signboard according to an alternative embodiment of the present invention. FIG. 18 is a partially enlarged perspective view illustrating a lateral

fastener coupled to a magnet or an aluminum plate in a channel signboard

according to an alternative embodiment of the present invention.

fastener 130 fixed to the upper plate 32 of the cover 30 and the horizontal

bottom plate 121.

With the above construction, the lateral fastener 130 is made of

transparent plastic material through which the light passes.

The construction of the lateral fastener 130 of the channel signboard

100 according to alternative embodiment of the present invention will now be

described in detail.

The lateral fastener 130 includes a vertical body 132, an upper support

portion 135 integrally formed with the upper end of the vertical body 132 and

having a bent portion, and a lower support portion 137 positioned under the

upper support portion 132 and integrally formed with the vertical body 132 in a

horizontal plate. A magnet 138 is fixed to the lower end of the vertical body

132, and is magnetically coupled to the steel horizontal bottom plate 121. Also, an aluminum plate 138a is fixed to the lower end of the vertical body 132

so as to increase the fastening force.

Preferably, the magnet 138 and the aluminum plate 138a are

alternatively fixed, thereby increasing the magnetic force 138 and the fastening

force of the aluminum plate 138a using the fastening screw.

The magnet 138 and the aluminum plate 138a may be formed through

injection molding when the lateral fastener 130 is formed. Also, the magnet

138 and the aluminum plate 138a may be inserted into the receiving groove

132b formed on the lower end of the vertical body 132 of the lateral fastener

130. In this instance, separate wings 132c are integrally formed on the lower

end of the receiving groove 132b, in order to easily couple the magnet 138 and

the aluminum plate 138a and to prevent the magnet 138 and the aluminum

plate 138a from being detached from the receiving groove 132b.

The process of assembling the channel signboard according to

alternative embodiment of the present invention will now be described.

Both ends of the upper cover plate 32 having a predetermined

character or pattern are inserted between the upper support portion 135 and the

lower support portion 137 which are integrally formed on the upper portion of

the vertical body 132 of the lateral fastener 130. An adhesive (not shown) is

applied on the contact surface between the upper plate 32 and the lower support portion 137.

The horizontal bottom plate 121 having the same character or pattern

as that of the upper cover plate 32 is fastened to the panel P of the channel

board by inserting a fastening screw 12a into the bottom plate 121.

After the horizontal bottom plate 121 is fixed to the panel P, the lower

upper portion of the upper cover plate 32 comes into close contact with the

outer surface of the horizontal bottom plate 121. As a result, the magnet 138

provided on the lower end of the vertical body 132 is magnetically coupled to

the steel horizontal bottom plate 121.

Also, the aluminum plate 138a which is a reinforcing member of the

lower surface of the lateral fastener 130 is fastened to the outer surface of the

horizontal bottom plate 121 by using a fastening screw 12b to increase the

fastening force.

The channel signboard according to another embodiment of the present

invention is completed by the above assembling process. In this instance, the

lighting equipment (not shown), such as neon lamp or incandescent lamp, is

installed on the horizontal bottom plate 121 of the channel signboard.

The features of the assembled channel signboard according an

embodiment of the present invention will now be described. First, since the lateral frame does not use a lateral frame of a bottom

metal plate formed on a conventional channel signboard, the total weight of the

channel signboard can be reduced, and the assembling operation can be easily

carried out. Also, a manufacturing cost of the channel signboard can be

lowered.

Second, since the lateral plastic fastener is provided in place of the

lateral metal frame, the light emitted from the lighting equipment can transmit

advertisement effect in night.

Third, the lateral fastener is fastened to the horizontal bottom plate by

means of the magnet, without using a fastening screw, thereby improving the

workability and shortening a working time.

Forth, the fastening force is increased by coupling the lateral fastener

with the horizontal bottom plate with the aluminum plate, as well as increasing

the strength of the lower surface of the lateral fastener.

Industrial Applicability

As can be seen from the foregoing, according to the channel signboard,

since the channel signboard of the present invention does not use a lateral

frame of a bottom metal plate formed on a conventional channel signboard, the total weight of the channel signboard can be reduced. Since the lateral plastic

fastener is provided in place of the lateral metal frame, the light emitted from the

lighting equipment can transmit the lateral fastener, as well as the front cover of

the front, thereby enhancing the advertisement effect in night.

Also, a manufacturing cost of the channel signboard can be lowered by

not using a lateral frame.

The lateral fastener is fastened to the horizontal bottom plate by means

of the magnet, thereby improving the workability and shortening a working time.

In addition, the channel signboard of the present invention utilizes the

aluminum plate as a reinforcing member of the lateral fastener, thereby

increasing the fastening force of the lateral fastener and also increasing the

strength of the lateral fastener.

While this invention has been described in connection with what is

presently considered to be the most practical and preferred embodiment, it is to

be understood that the invention is not limited to the disclosed embodiment and

the drawings. On the contrary, it is intended to cover various modifications and

variations within the spirit and scope of the appended claims.
