  However, in such a shutter, the shutter body is often opened during the day to capture the sunlight, and the shutter body is generally closed only at night.

  For this reason, the heat insulation mentioned above can be exhibited only at night, and the new subject which makes it possible to exhibit the heat insulation function of an opening part also in the daytime was discovered.

  It is an object of the present invention to provide a shutter that enables daylighting from a vertical frame and that can exhibit heat insulation by closing the shutter even in the daytime.

  The shutter according to the first aspect of the present invention includes a shutter main body that opens and closes an opening of a building, a guide rail that guides an end of the shutter main body so as to be movable up and down, and a guide that projects from a peripheral edge of the opening. A rail is attached and a resin vertical frame having transparency.

  That is, since the vertical frame to which the guide rail is attached is made of a resin having transparency, light can be taken into the opening through the vertical frame even when the shutter body is closed. For this reason, even if the shutter body is closed in the daytime, it is possible to perform daylighting indoors, and the shutter can be used as a heat insulating member in the daytime.

  In the shutter according to the second aspect of the present invention, the vertical frame is formed of a translucent resin.

  That is, the vertical frame is formed of a translucent resin, and visibility from the outside to the indoor can be reduced as compared with the case where the vertical frame is formed of a transparent resin. Thereby, indoor peeping can be suppressed and privacy can be protected.

  In the shutter according to the third aspect of the present invention, the vertical frame is formed in a hollow shape, and semitransparent ribs are provided in the vertical frame at intervals in the projecting direction.

  That is, the vertical frame is formed in a hollow shape, and a rib is provided in the vertical frame. Thereby, the rigidity of a vertical frame can be improved.

  And the rib provided in the vertical frame is translucent, and the transparency can be lowered by the translucent vertical frame and the translucent rib, and the visibility from the outdoor to the indoor through this rib is further reduced. Can be achieved. Thereby, the rib which reinforces a vertical frame can be used effectively.

  In the shutter according to the fourth aspect of the present invention, the vertical frame is formed in a hollow shape with a transparent resin, and opaque ribs are provided in the vertical frame at intervals in the projecting direction.

  That is, the vertical frame is formed in a hollow shape, and a rib is provided in the vertical frame. Thereby, the rigidity of a vertical frame can be improved.

  Moreover, the rib provided in the vertical frame is opaque, and the line of sight from the outdoor to the indoor through the vertical frame can be blocked by the opaque rib. Thereby, the rib which reinforces a vertical frame can be utilized effectively, indoor peeping can be suppressed, and privacy can be aimed at.

  And since the vertical frame was formed with transparent resin, the lighting effect can be heightened compared with the case where it forms with translucent resin.

  In the shutter according to the fifth aspect of the present invention, the angle of the rib with respect to the extending direction of the vertical frame from the building is set so that the opening is not positioned on the extension line of the rib.

  That is, since the rib is provided so that the opening is not positioned on the extension line of the rib provided in the vertical frame, the line of sight along the rib does not reach the inside of the opening directly. Thereby, the privacy protection effect by the rib provided in the vertical frame can be enhanced.

  Since the present invention has the above-described configuration, it is possible to perform daylighting from the vertical frame, and it is possible to exhibit heat insulation by closing the shutter even in the daytime.

Is provided. The guide rail 44 is made of aluminum and is opaque, but may be made of a resin having transparency.

  The attachment portion of the guide rail 44 to the vertical frame main body 28 will be described. On the extension of the outer end face 28D of the vertical frame main body 28, a first fixing piece 28F extending toward the inner side of the outer frame is formed. A second fixing portion 44A extending from the guide rail 44 is fixed to the first fixing piece 28F. Further, an inwardly extending piece 28G extending from the inner surface 28B toward the inner side of the outer frame is formed on the building 12 side from the outer end surface 28D of the vertical frame main body 28, and from the tip of the inwardly extending piece 28G. The second fixed piece 28 </ b> H extending in a direction away from the building 12 extends. A second fixing portion 44B extending from the guide rail 44 is fixed to the second fixing piece 28H.

  In the vertical frame main body 28 formed in a hollow shape, a plurality of ribs 46 connecting the outer surface 28A and the inner surface 28B are formed at intervals in the projecting direction of the vertical frame 26. The frame body 28 is reinforced. The ribs 46 are integrally formed with the vertical frame body 28 and are formed of a translucent resin as with the vertical frame body 28.

  Each rib 46 is provided so as to be orthogonal to the outer surface 28A and the inner surface 28B extending in the extending direction H of the vertical frame 26, and the window glass 18 (of the building 12) is formed on the extension line M of the rib 46. The opening 14) is configured not to be located.

  The effect | action of this embodiment which concerns on the above structure is demonstrated.

  That is, a vertical frame 26 provided with guide rails 44 projects from the side of the opening 14 of the building 12, and the vertical frame 26 is made of a resin having transparency. For this reason, the light T outside the vertical frame 26 is taken into the space 102 between the window glass 18 and the shutter main body 22 through the vertical frame 26, and indoors I through the window glass 18 provided in the building 12. Is taken in.

  Thus, even if the shutter body 22 is closed, the sunlight can be taken into the indoor I through the vertical frame 26. For this reason, the shutter main body 22 can be closed even during the day, and the heat insulating function due to the vertical frame 26 being made of resin can be exhibited.

  Therefore, it is possible to promote the use of the shutter 10 in the daytime and obtain a heat insulating effect by the resin vertical frame 26. Thereby, the improvement of a heating / cooling efficiency and the dew condensation prevention effect can be acquired.

  Further, the vertical frame 26 is formed of a translucent resin, and compared with the case where the vertical frame 26 is formed of a transparent resin, the line of sight S from the outdoor O to the indoor I can be prevented and visibility can be reduced. . Thereby, peeping in the indoor I can be suppressed and privacy can be protected.

  The vertical frame 26 is formed in a hollow shape, and an outer surface 28 </ b> A constituting the outer side and an inner surface 28 </ b> B constituting the inner side are connected at a plurality of locations by ribs 46. Thereby, the rigidity of the vertical frame 26 can be increased.

  At this time, the ribs 46 provided on the vertical frame 26 are translucent, and the translucency can be lowered by the translucent vertical frame 26 and the translucent ribs 46. Thereby, the visibility from the outdoor O to the indoor I through the rib 46 can be further reduced, and the rib 46 that reinforces the vertical frame 26 can be used effectively.

  And the angle of each rib 46 with respect to the extending direction H of the vertical frame 26 from the building 12 is set on the extension line M of these ribs 46 so that the window glass 18 (opening 14) of the building 12 is not located. ing. For this reason, the line of sight S along the rib 46 does not reach the inside of the window glass 18 (opening 14) directly. Thereby, the privacy protection effect by the rib 46 provided in the vertical frame 26 can be heightened. In addition, when the vertical frame 26 is shape | molded with transparent resin, the rib 46 is not necessarily required.

  In other words, in the present embodiment, the vertical frame 26 is formed of a transparent resin, and the ribs 110 provided in the vertical frame main body 28 are opaque. This opaque rib 110 is formed by coloring the rib 110 integrally formed with the vertical frame body 28 with a transparent resin to make it opaque, a method of forming only the rib 110 with an opaque resin, or other opaque materials such as metal. The method of forming the rib 110 with a material is mentioned.

  Here, the “opaque resin” refers to a plate material having a thickness of 4 mm and a surface roughness Ra of 0.5 μm (JIS B 0601) formed using the resin. It is a resin material having a light transmittance (JIS K 7105) of less than 20%.

  The “transparent resin” is a visible light transmission of a plate material having a thickness of 4 [mm] and a surface roughness Ra of 0.5 [μm] (JIS B 0601) formed using the resin. It is a resin material having a rate (JIS K 7105) exceeding 80%.

  In the case of the rib 110 made transparent by coloring the transparent resin or the rib 110 made of other materials, the visible light transmittance (JIS K 7105) of the rib 110 is less than 20% as opaque. To do.

  Also in the present embodiment having the above-described configuration, it is possible to obtain the same operational effects as those of the first embodiment.

  Further, in the present embodiment, the vertical frame 26 is formed in a hollow shape, and an outer surface 28 </ b> A constituting the outer side and an inner surface 28 </ b> B constituting the inner side are connected by the rib 110. Thereby, the rigidity of the vertical frame 26 can be improved.

  Further, the rib 110 provided in the vertical frame 26 is opaque, and the line of sight S from the outdoor O to the indoor I via the vertical frame 26 can be blocked by the opaque rib 110. Thereby, the rib 110 which reinforces the vertical frame 26 can be effectively used to suppress the peeping in the indoor I and to protect privacy.

  And since the vertical frame 26 was formed with transparent resin, the lighting effect can be heightened compared with the case where it forms with translucent resin.

  In each of these embodiments, the case where the ribs 46 and 110 provided on the vertical frame body 28 are orthogonal to the projecting direction H of the vertical frame 26 has been described, but the present invention is not limited to this.

  For example, in each of the ribs 46 and 110, the ribs 46 and 110 are arranged on the vertical frame 26 so that the other ends 46B and 110B connected to the outer surface 28A are located on the building 12 side from the one ends 46A and 110A connected to the inner surface 28B.
