Referring to FIG. 7A, the adhesive 300 may be filled over the entire adhesive accommodating groove 150. FIG. 7B is a cross-sectional view taken along the line Z-Z 'of FIG. 7A. As shown in FIG. 7A, the adhesive is filled in only a portion of the adhesive accommodating groove 150, and the adhesive 300 is filled while fixing the side frame along the cross section of the transmission window 11 to the cross section of the transmission window 11. You can also increase the interval. The adhesive 300 may be a plastic adhesive.

The fixing step S54 of the transmission window to the side frame is a step of fixing the transmission window to the side frame. Referring to FIG. 8, one end of the transmission window 11 may be in close contact with the flexible frame 110 through the transmission window insertion hole 140. In addition, in consideration of the time when the adhesive 300 is hardened and bound to the transmission window 11, the flexible frame 110 may be bent along the end of the transmission window 11. As a result, as shown in FIG. 9, the flexible frame 110 may be bent along the end of the transmission window 11 to be fixed to the transmission window 11. At this time, the adhesive 300 hardened by the adhesive accommodating groove 150 and bound to the transmission window 11 acts as a ring caught by the adhesive accommodating groove 150, and thus, the transparent window 11 is applied by the elastic force of the flexible frame 110. ) And the flexible frame 110 may be prevented from being separated.

The fixing step S55 of the base plate to the side frame is a step in which the base plate is tightly fixed to the step 160. Referring to FIG. 10, the base plate 12 provided with the illumination 15 is inserted from the opposite side of the transmission window 11, is in close contact with the step 160, and is attached to the step 160 by a screw (not shown). Can be fixed. Thereby, the three-dimensional signage 1 as shown in FIG. 11 can be completed.

In summary, the present invention adopts a flexible aluminum channel bar for bending the side frame. In addition, the transmission window should be made of a transparent plastic having excellent light transmittance for light transmission. However, when fixing the plastic to the aluminum channel bar, using a screw may harm the appearance of the three-dimensional sign, it is preferable to fix the transmission window to the side frame using an adhesive. However, due to the difference in material, it is impossible to attach aluminum and plastic with an adhesive. Thus, molding should be performed to fix the plastic window on the side frame made of aluminum. However, when the molding is performed to fix the transmission window to the side frame, the manufacturing cost of the three-dimensional sign may increase. Thus, the present invention uses a low-cost plastic adhesive adhesive to secure the transmission window to the side frame. As previously seen, the adhesive is filled into the adhesive receiving groove and the end of the transmission window is bound to the adhesive. Thereby, when the side frame acts on the elastic force in the direction to be separated from the transmission window, it is possible to prevent the adhesive bound to the transmission window to act as a ring to catch the adhesive accommodating grooves to try to separate the side frame from the transmission window.

Preferred embodiments of the present invention described above are disclosed for purposes of illustration, and those skilled in the art will be able to make various modifications, changes, and additions within the spirit and scope of the present invention. Additions should be considered to be within the scope of the following claims.
