Abstract

PROBLEM TO BE SOLVED: To prevent the deformation of a molding by setting the sectional area of an upper edge rain gutter smaller than that of a side edge rain gutter, and linearly protruding and recessing a slide core to a molding space. SOLUTION: An upper edge molding 11A is connected to a side edge molding 11B so that an upper edge rain gutter 15 is continued to a side edge rain gutter 19. The upper edge rain gutter 15 and the side edge rain gutter 19 have mutually similar substantially V-shaped sections, and the sectional area (a) of the upper edge rain gutter 15 is set smaller than the sectional area (b) of the side edge rain gutter 19. Since the upper edge rain gutter 15 and the side edge rain gutter 19 have the similar sectional forms, a second slide core may be linearly protruded and recessed to the molding space in the extrusion molding of a molding 11, whereby the change of the flow of the resin extruded from the molding space can be more moderated.

Changes in the amount and flow of the resin extruded from 32 can be reduced as compared with the related art, whereby deformation occurring at a specific portion of the molding 11 can be reduced. In particular, the transparent plate-shaped body 10
According to this, since the cross-sectional area of the upper side rain garter 15 is set to be smaller than the cross-sectional area of the side side rain garter 19, the rising dimension of the upper side rising portion 13 of the upper side molding 11A can be reduced, thereby providing good appearance and good appearance. Deformation prevention can be achieved.

Further, according to such a transparent plate-shaped body 10 with a frame, the upper side rain garter 15 and the side side rain garter 19 are provided.
Have a similar cross-sectional shape, when the molding 11 is extruded, the second slide core
34 may be protruded and retracted in a straight line.
The change in the flow of the resin extruded from the resin can be further reduced.

FIG. 5 shows a transparent plate-like body 50 with a frame according to a second embodiment. In the embodiment described below, the members and the like already described in FIG. 1 are denoted by the same reference numerals or corresponding reference numerals in the drawings to simplify or omit the description.

As shown in FIG. 5, a transparent plate-like body 50 with a frame is provided.
In the moldings 51A and 51B, the grip length (the depth in the left-right direction in the figure) of the upper side mounting portion 52 and the side side mounting portion 56 with respect to the upper side 73 and the side side 74 of the transparent plate 72 is set to be short. At the same time, the upper side rising portion 53 and the side side rising portion 57 are formed to rise from the entire upper surface of the upper side mounting portion 52 and the side side mounting portion 56, respectively. Accordingly, in the molding 51A, the upper side rain garter 55 is formed between the surface 72B of the transparent plate 72 and the flat surface 54A of the upper flange 54, and the molding 51B is formed in the transparent plate 72.
A side rain garter 59 is formed between the surface 72B of the side and the flat surface 58A of the side flange 58.

According to such a transparent plate-like body 50 with a frame, the structure is basically the same as that of the transparent plate-like body with a frame 10 of the first embodiment described above. An effect similar to that of the first embodiment in that no deformation occurs can be obtained. In the transparent plate-shaped body 50 with a frame, since the inner side surfaces of the upper side rain garter 55 and the side side rain garter 59 are the surface 72B of the transparent plate-shaped body 72, the transparent plate-shaped body 72 does not climb over the step. Rain water adhering to the surface 72B is removed by the upper side rain gutter 55 and the side side rain gutter.
Can be accommodated in 59. That is, this transparent plate-shaped body with a frame
According to 50, rainwater adhering to the surface 72B of the transparent plate 72 can be drained more efficiently than the transparent plate 10 with the frame of the first embodiment described above.

It should be noted that the present invention is not limited to the above-described embodiments, but can be appropriately modified, improved, and the like.
Material and shape of upper side, side side, upper side molding, side molding, upper side mounting section, upper side upper section, upper side flange section, side side mounting section, side side upper section, side side flange section, upper side rain gutter, side side rain gutter, etc. The size, form, number, location, and presence or absence of coloring are arbitrary as long as the present invention can be achieved.

[0028]

As described above, according to the present invention, since the rain garter is formed not only on the side molding but also on the upper molding, the influence of the external force applied to the lateral molding when an external force is applied, The upper side mall does not greatly affect the influence of the external force. Therefore, the influence of the external force is not noticeable. Further, since the cross-sectional area of the upper side rain garter is set smaller than the cross-sectional area of the side side rain garter, deformation is less likely to occur at a specific portion of the extruded molding, and the appearance is not impaired. Further, when the upper side rain garter and the side side rain garter have similar cross-sectional shapes, when extruding the molding, the slide core may be linearly protruded and retracted with respect to the molding space. It can be further prevented.
