  According to a third aspect of the present invention, in the resin window panel according to the second aspect of the present invention, the ridge extends so as to surround the window region from at least two adjacent directions.

  According to a fourth aspect of the present invention, in the resin window panel according to any one of the first to third aspects, a plurality of the protruding portions are arranged in parallel with each other, and between adjacent protruding portions. The recess is formed over the entire longitudinal direction.

  According to a fifth aspect of the present invention, in the resin wind panel according to any one of the first to fourth aspects, the rising surface of the ridge portion facing the window region side is a protrusion in the outer region. It is characterized in that it is inclined so as to form an obtuse angle between the protruding surface of the strip and the window region side.

  A sixth aspect of the present invention is the resin window panel according to any one of the first to fifth aspects, wherein the protruding portion is a triangle having a protruding end as an apex and an internal angle of the apex forming an acute angle. It has a cross section of shape.

  According to the first aspect of the present invention, the flow of the liquid coating agent accumulated at the base end of the protruding portion during the formation of the coating film into the window region is regulated by the protrusion, so that the trace of the liquid coating agent flows in. Can be prevented from being formed in the window region.

  According to the second aspect of the present invention, since the protruding portion extends so as to cover the entire window region as viewed from one direction along the plate surface of the wind panel body, the liquid coating agent is formed on the base end of the protruding portion. The liquid coating agent can be prevented from entering the window region from above, no matter where it is dropped.

A resin wind panel 1 is attached in a fitted state. The resin window panel 1 has a substantially rectangular annular reinforcing rib 15 (see FIGS. 2 to 4) extending over the entire outer periphery, and is applied over the entire outer periphery of the reinforcing rib 15. (Not shown) is fixed to the opening 5.

  As shown in FIGS. 2 to 4, the resin window panel 1 includes a light-transmitting substantially rectangular plate-like resin panel 7, and a substantially rectangular annular non-light-transmitting member is provided on the outer peripheral edge of the back surface of the resin panel 7. The outer frame 13 that shields light is formed by molding the frame portion 9 with two colors. Further, the resin panel 7 is exposed inside the outer region 13 (frame portion 9), and a substantially rectangular window portion region 11 having translucency is formed in the exposed region. A window panel body 10 is formed by the resin panel 7 and the frame portion 9 (the window region 11 and the outer region 13). A coating film (not shown) is formed on the front and back surfaces of the window region 11 and the outer region 13, that is, on the entire front and back surfaces of the window panel body 10 by applying a liquid coating agent L (described later).

  On the back surface side of the frame portion 9, that is, on the back surface side of the outer region 13, the reinforcing rib 15 as a projecting portion is provided so as to surround the window region 11.

  In the outer region 13 on the side of the window region 11 from the reinforcing rib 15, an outer ridge portion 17 and an inner ridge portion 18 having a triangular cross-section protruding to the back surface side are provided with inclined surfaces 17 c and 18 c on the inner side (window portion). Toward the region 11 side) so as to surround the window portion region 11 from three directions in parallel with each other in a substantially gate shape, and a concave section 20 having a right-angled triangular cross section is provided between the two in the entire longitudinal direction. It is formed over. The outer ridge 17 has a horizontal ridge 17a extending horizontally corresponding to one side of the window region 11, and 90 ° from the both ends of the horizontal ridge 17a. It is composed of two vertical ridges 17b extending vertically corresponding to two sides following one side, and similarly, the inner ridge portion 18 also extends horizontally corresponding to one side of the window region 11. A horizontal ridge 18a and two vertical ridges 18b extending vertically corresponding to two sides that follow both sides of one side of the window region 11 by changing the direction from both ends of the horizontal ridge 18a by 90 °. Has been.

  Next, a method for forming a coating film on the entire front and back surfaces of the wind panel body 10 will be described with reference to FIG.

  First, the window panel body 10 is completely immersed in the liquid coating agent L in a container (not shown). After that, as shown in FIG. 5, the reinforcing rib 15 is located above the window region 11, that is, on the pulling direction X side of the window panel body 10, and the projecting surface of the reinforcing rib 15 is with respect to the pulling direction X. The wind panel main body 10 is pulled up from the liquid coating agent L in a posture inclined to the liquid surface side of the liquid coating agent L. Then, the excess liquid coating agent L adhering to the window panel main body 10 flows down from the window panel main body 10, and after a while, most of the flow is settled.

  Then, the liquid coating agent L adheres and remains almost uniformly on the surface of the wind panel body 10. At this time, as shown in FIG. 5, the liquid coating is applied to the base end on the window region 11 side on the upper side of the reinforcing rib 15. A liquid mass of the agent L is formed by the surface tension. Further, a liquid reservoir of the liquid coating agent L is formed at the base end of the horizontal protrusion 17a on the side opposite to the window portion region 11 and the concave portion 20. At this time, the inclined surface 18c and the outer region 13 form an obtuse angle on the side of the window region 11 at the base end of the horizontal protrusion 18a on the side of the window region 11, and the liquid coating agent L hardly accumulates and no liquid mass is formed. .

  The liquid mass of the liquid coating agent L formed at the base end on the side of the window region 11 on the upper side of the reinforcing rib 15 gathers and becomes large, cannot withstand its own weight, and flows down to the window region 11 side. And after the liquid coating agent L reaches | attains the counter-window part area | region 11 side base end of the horizontal protrusion 17a of the outer side protrusion part 17, it merges with the liquid reservoir of the liquid coating agent L formed in this base end, It spreads in the direction (horizontal direction) in which the horizontal ridge 17a extends, is guided by both vertical ridges 17b from both sides of the horizontal ridge 17a, and flows down in a direction along the vertical ridge 17b. Further, the liquid coating agent L that has not flowed down in the direction along the vertical ridge 17b forms a liquid mass at the tip of the horizontal ridge 17a, and then drops in a direction away from the window region 11 because it cannot withstand its own weight. . In this way, the flow of the liquid coating agent L from the side into the window region 11 is restricted by the two vertical protrusions 17b. Further, the liquid coating agent L that does not drop from the tip of the horizontal ridge 17a and gets over the horizontal ridge 17a flows into the concave portion 20 and a liquid pool of the liquid coating agent L formed on the concave portion 20 is formed. It merges and spreads in the direction (left-right direction) in which the concave line portion 20 extends, and is guided by both vertical protrusions 18b from both sides of the concave line portion 20 and flows down in the direction along the vertical protrusion 18b. Further, the liquid coating agent L that has not flowed down in the direction along the vertical protrusion 18b forms a liquid mass at the tip of the horizontal protrusion 18a, and then drops in a direction away from the window region 11 because it cannot withstand its own weight. . In this way, the flow of the liquid coating agent L from the side into the window region 11 is repeatedly restricted by the two vertical protrusions 18b. Therefore, the flow of the liquid coating agent L into the window region 11 is restricted by the outer protrusions 17 and the inner protrusions 18, so that traces of the liquid coating agent L are formed in the window region 11. Is prevented.

  Thereafter, the liquid coating agent L is dried and a coating film is formed on the entire surface of the wind panel body 10.

(Embodiment 2)
FIG. 6 shows a resin window panel 1 according to Embodiment 2 of the present invention. In this Embodiment 2, it replaces with the outer side protrusion part 17 and the inner side protrusion part 18 in the formation location of the outer side protrusion part 17 and the inner side protrusion part 18, and the inclined surface 19c is set inside (window part area | region 11 side). The projecting ridge portion 19 having a substantially trapezoidal cross section is formed in a substantially gate shape so as to surround the window region 11 from three directions. The ridges 19 extend horizontally corresponding to one side of the window region 11, and continue on both sides of one side of the window region 11 by turning 90 ° from both ends of the horizontal ridge 19 a. It consists of two vertical ridges 19b extending vertically corresponding to the two sides. In addition, a recessed portion 21 having a substantially half-moon shape is formed on the protruding end surface of the protruding portion 19 over the entire longitudinal direction of the protruding portion 19.

  The method of forming a coating film on the window panel body 10 of the present embodiment is the same as that of the embodiment 1, but when the window panel body 10 is pulled up from the liquid coating agent L, as shown in FIG. A liquid mass of the liquid coating agent L is formed by surface tension at the base end of the upper side of the window portion region 11. In addition, a liquid reservoir of the liquid coating agent L is formed at the base end of the horizontal protrusion 19 a on the side opposite to the window portion region 11 and the recessed portion 21. At this time, since the inclined surface 19c and the outer region 13 form an obtuse angle at the base end of the horizontal protrusion 19a on the window region 11 side, the liquid coating agent L hardly accumulates and no liquid mass is formed.

  After that, in the process of maintaining the posture at the time of pulling up and drying, the liquid mass of the liquid coating agent L formed at the base end side of the window region 11 on the upper side of the reinforcing rib 15 gathers and becomes large and cannot withstand its own weight. It disappears and flows down to the window area 11 side. Then, after the liquid coating agent L reaches the opposite end portion 11 side base end of the horizontal protrusion 19a of the protrusion 19, the liquid coating agent L merges with the liquid pool of the liquid coating agent L formed at the base end, and the horizontal protrusion It spreads in the direction in which the strip 19a extends. And it is induced | guided | derived by both the vertical protrusions 19b from the both sides of this horizontal protrusion 19a, and flows down in the direction along this vertical protrusion 19b. In this way, the flow of the liquid coating agent L from the side into the window region 11 is restricted by the two vertical protrusions 19b. Further, the liquid coating agent L that has reached the front end surface of the horizontal ridge 19a spreads in the extending direction (left-right direction) of the recessed portion 21 in the recessed portion 21 of the horizontal ridge 19a, and vertical ridges 19b on both sides. It flows down from the recessed portion 21 of the. As described above, even if the liquid coating agent L reaches the tip surface of the ridge portion 19, the liquid coating agent L hardly gets over the ridge portion 19. Therefore, according to the present embodiment, it is possible to prevent the trace of the flow of the liquid coating agent L from being formed in the window region 11 as in the first embodiment.
