The present invention for achieving the above object, in the channel sign fastener for fastening the upper plate 36 in the channel signboard having a bottom plate and the side frame 34 to the side frame 34, therein A base 20 shaped like a flat plate (xz flat plate) containing a metal piece 22; An underlaying protrusion (27) and an upper protrusion (25) formed to protrude (y-axis direction) from the base (20) to form a coupling groove (26) capable of biting the upper plate (36); In the middle of the base 20, at least two bends 23 and 24 are formed so that the lower end (-z-axis direction) 21 is in contact with the inner surface of the side frame 34, wherein The point where the bottom support protrusion piece 27 protrudes is characterized in that the curved point (23, 24).

Another feature of the present invention is that at least the degree of protruding (y-axis direction) of the underlaying protruding piece 27 is not uniform along the base plate direction (x-axis direction), and thus can be flexed well according to a sign pattern. Is in the structure.

Hereinafter, with reference to the accompanying drawings, it will be described embodiments of the configuration according to the present invention in detail.

2 is a cross-sectional view of the cover fastener of the channel signboard according to the present invention. As shown in the figure, the base 20, the lower end 21 of the base, and the lower support protrusions 27 and the upper protrusions 25 above and below the coupling grooves 26 into which the upper plate can be fitted, respectively. It consists of. Characteristically, the metal piece 22 is contained in the fastener base 20.

In one embodiment, since the thickness of the acrylic board of the cover top plate 36 is usually 3mm, the width of the coupling groove 26 is the same, and the thickness of the metal piece 22 is preferably about 0.2mm accordingly.

The base 20 of the fastener is basically a flat plate (x-z flat plate) or a strip. The base 20 of the fastener is bent (23, 24) is formed in the middle of the base so that the lower end 21 is coupled to the side frame of the channel sign, in close contact with the inside of the side frame. At least two bends are required, and the degree of bend may vary, but a shape that is curved at right angles may be appropriate. Then, a kind of jaw is formed in the outer side (surface in contact with the side frame) of the lower end 21.

In this case, the metal piece 22 inside is also bent twice. Although the drawings also show that the metal piece is bent at a right angle, the present invention is not limited thereto. In particular, it will be apparent from the description of FIG. 4 to be described later, in order to be curved in a curved pattern, it is preferable that the cross section of the inner metal piece 22 is formed in an 'S' shape.

The characteristic structure of the present invention is that, in the case of PVC extrusion of the fastener, for the convenience of manufacturing, a point at which the underlay protrusion 27 protrudes is formed at the same position as the bend points 23 and 24. to be. The advantage of this structure becomes apparent with reference to FIG. 3.

Figure 3 shows an aspect using a cover fastener of the present invention in the channel signage in cross-sectional format.

3, the support 32 supporting the neon tube 33, the fasteners 20 and 21 holding the side frame 34 of the channel signboard, the cover top plate 36 as a coupling groove, and the lower end of the fastener. A piece bolt 35 is shown coupling 21 to the side frame 34. The diameter of the neon tube is usually 12mm.

The base bottom end 21 of the fastener according to the present invention is to be tightly coupled to the inside of the side frame 34. Although the lower end of the fastener is the same as the conventional side frame and piece coupling 35, in the present invention is to be coupled to the inside of the side frame. To do this, as described above, there are two bends.

As shown in the figure, the end of the cover upper plate 36 is placed on the lower support protrusion piece 27 protruding from the fastener base 20. Here, by the two bends, the length of the lower side of the underside protruding piece 27 itself, which protrudes at the same position as the position of the bend, becomes shorter than the length of the side contacting the cover upper plate 36. Therefore, the torque which the underlaying projection piece 27 receives by the cover upper plate 36 becomes small.

In other words, since the width of the cover top plate 36 generally corresponds to the width of the side frame 34, the end of the cover top plate 36 is placed to the position of the outer surface of the base bottom end 21 of the fastener. do. A portion of the cover fastener supporting the cover upper plate 36 also supports the lower end 21 of the base in addition to the lower support protrusion 27. Moreover, the inside metal piece 22 also plays a part.

4 is a view showing an embodiment of an aspect in which the bottom protrusion piece of the cover fastener is extended. In the case of the upper projection piece 25 may be a similar discontinuous aspect, but aesthetic appearance continuous aspect is preferable. The figure also shows the coordinate axis to clarify the direction of the solid.

The bases 20 and 21 of the fastener described in FIG. 2 may be referred to as x-z planes. The upper and lower protrusions 25 and 27 protruding in the Y-axis direction extend along the x-axis, and FIG. 4 shows that the protrusion may not be continuous. In addition, the aspect in which the degree of protrusion extends may be rectangular sawtooth, trapezoidal sawtooth, or sinusoidal.

The key here is that the degree of protrusion may not be uniform. The effect of this is that a fastener with a plate type base 20 can bend more easily along the x axis. Since the signboard pattern has various shapes, the side frame and the cover top plate may also be curved, thereby allowing the cover fastener to be bent together.

Therefore, the protrusion degree of the protrusion piece 27 formed in order to support and snap | cover the cover upper plate 36 is made to be uneven. Further, as a side effect, it can be convenient to cut the length of the cover fastener in the x-axis direction to the extent necessary.

The present invention having the configuration as described above is provided with a cover fastener which can be manufactured relatively simply, and thus the torque applied to the underlaying projection piece of the cover fastener is reduced, so that the fastener has a durable effect.

In addition, the fastener having the flat plate type base is changed in the degree of protrusion of the upper and lower protrusion pieces, and according to the pattern of the channel signboard, there is also an effect that can be easily bent. Incidentally, there is also an effect that the length of the cover fastener can be easily cut according to the pattern length of the channel signboard as necessary.

As such, it can be bent well as needed and can be easily cut, which helps to produce a channel signboard more conveniently and quickly than the work on the existing channel letter signs. Therefore, there is an effect that can be produced directly by the advertiser at a lower price as a whole.

When the cover fastener according to the present invention is used, it can be more beautiful without aesthetic problems and does not rust. The color of the cover fastener can also be manufactured in various colors, so there is no need for a separate paint coating. That is, it is more convenient in terms of use compared to existing products.
