The shutter-integrated sash device 100 includes a frame 1, two shoji 2, a shutter section 3, and a ventilation panel 4.

The frame 1 is fixed to a frame 91. The frame 1 and a shutter box 33, which will be described later, are fixed to a frame 91 with fixtures 93. The fixture 93 is installed closer to the indoor side than the outer wall 94. The shutter-integrated sash device 100 is installed, for example, when a new building is constructed.

The frame body 1 is formed into a four-sided frame shape. The frame 1 is arranged along the periphery of the opening 92 of the building. The frame 1 has an upper frame 11, a lower frame 12, and a pair of vertical frames 13, 13 (see FIG. 3). The upper frame 11 and the lower frame 12 extend in the width direction. The vertical frame 13 extends in the vertical direction. The upper frame 11 connects the vertical middle of the pair of vertical frames 13, 13. The lower frame 12 connects the lower ends of the pair of vertical frames 13, 13.

As shown in FIG. 3, a guide rail 14 is fixed to the outdoor end of the vertical frame 13 using a set screw 14a. The guide rail 14 extends in the vertical direction. The guide rail 14 has a pair of guide walls 14b, 14b. The guide walls 14b, 14b each extend in the vertical direction. The guide walls 14b, 14b are arranged to face each other in the indoor/outdoor direction with the holding space 14c interposed therebetween. The holding space 14c opens inward in the width direction and extends in the vertical direction. The holding space 14c passes through the guide rail 14 in the vertical direction. An outer end 31a in the width direction of the shutter body 31 and an outer end 43a in the width direction of the vertical ventilation frame 43 (see FIG. 4), which will be described later, are inserted into the holding space 14c. The outer end in the width direction of the shutter body 31 and the outer end 43a in the width direction of the vertical ventilation frame 43 are supported by a pair of guide walls 14b, 14b so as to be movable in the vertical direction.

The shoji 2 is a sliding door that can be slid in the width direction inside the frame 1. The type of fittings installed in the shutter-integrated sash device 100 can be set as appropriate.

As shown in FIG. 1, the shutter section 3 includes a shutter body 31 and a shutter box 33. The shutter section 3 opens and closes an opening 92 such as a window or door of a building on the outdoor side of the shoji 2. FIG. 1 shows a state in which the shutter section 3 is closed. The shutter portion 3 corresponds to a closing device in the claims.

The shutter body 31 is formed into a planar shape that can close a portion of the opening 92 (see FIG. 2) closer to the outdoors than the shoji 2. A baseboard portion 31b is provided at the lower end of the shutter body 31.

The shutter box 33 houses the shutter body 31. The shutter main body 31 is wound up around a winding shaft (not shown) and can be stored inside the shutter box 33.

The ventilation panel 4 is located below the shutter body 31 when the shutter body 31 is closed. The ventilation panel 4 is arranged between the lower end of the baseboard portion 31b of the shutter body 31 and the lower frame 12. The ventilation panel 4 includes a ventilation frame 40 and a plurality of ventilation slats 45.

The ventilation frame 40 is formed into a four-sided frame shape. The ventilation frame 40 has an upper ventilation frame 41, a lower ventilation frame 42, and a pair of vertical ventilation frames 43, 43. The upper ventilation frame 41 and the lower ventilation frame 42 extend in the width direction. The ventilation vertical frame 43 extends in the vertical direction. The upper ventilation frame 41 connects the upper ends of the pair of vertical ventilation frames 43, 43. The lower ventilation frame 42 connects the lower ends of the pair of vertical ventilation frames 43, 43. A baseboard portion 42b is provided at the lower part of the ventilation lower frame 42.

The ventilation slat 45 has a long shape in the width direction. The ends of the ventilation slats 45 in the width direction are supported by the ventilation vertical frames 43. Thereby, the opening between the pair of ventilation vertical frames 43, 43 can be closed. As shown in FIG. 2, a plurality of ventilation slats 45 are arranged at intervals in the vertical direction. The ventilation slat 45 is formed into a plate shape. The plate surface of the ventilation slat 45 is arranged along a surface that gradually goes downward toward the indoor side. Between the upper and lower ventilation slats 45 is a ventilation section 46 that communicates the outdoor side and the indoor side. As shown in FIG. 4, the vertical frame 13 projects outward from the building frame 91, and a guide rail 14 is fixed to the outdoor end of the vertical frame 13, and the guide rail 14 is connected to the ventilation vertical frame of the ventilation panel 4. 43, the ventilation section 46 is located in the opening 92 of the building on the outdoor side of the shoji 2. The shape of the ventilation slat 45 can be appropriately installed as long as the ventilation portion 46 is formed.

As shown in FIG. 2, the lower end of the upper ventilation slat 45 is located at a lower position than the upper end of the ventilation slat 45 immediately below. This makes it impossible to see the indoor side when viewing the shutter body 31 from the front from the outdoor side.

A shutter locking device 34 is provided on the indoor side of the baseboard portion 31b of the shutter body 31. The shutter locking device 34 can lock and unlock the ventilation upper frame 41. The shutter locking device 34 corresponds to a second locking device in the claims. When the ventilation panel 4 is removed, the shutter locking device 34 can lock and unlock the lower frame 12.

A panel locking device 44 is provided on the indoor side of the baseboard portion 42b of the ventilation panel 4. The panel locking device 44 can lock and unlock the lower frame 12. The panel locking device 44 corresponds to a first locking device in the claims.

When installing the ventilation panel 4, the shutter body 31 is left open to a greater extent than the height of the ventilation panel 4. The ventilation panel 4 is tilted so that one side in the width direction of the ventilation panel 4 is at a low position and the other side in the width direction is at a high position. The end portion 43a of the ventilation vertical frame 43 is fitted into the guide rail 14. The ventilation lower frame 42 of the ventilation panel 4 is installed above the lower frame 12 of the frame body 1 so that the ventilation panel 4 is horizontal. The baseboard portion 42b of the ventilation lower frame 42 and the lower frame 12 are locked by a panel locking device 44.

With the ventilation panel 4 installed, the shutter body 31 can open, close, and close the area above the ventilation panel 4. The shutter body 31 is opened by lifting the lower part of the shutter body 31 from the closed state and winding it around the shaft. From the open state of the shutter body 31, the baseboard portion 31b of the shutter body 31 is pulled down and wound back around the shaft, thereby closing the shutter body 31.

In the shutter-integrated sash device 100 configured in this way, outside air can be introduced into the indoor side from the ventilation section 46 that communicates the outdoor side and the indoor side, so that the opening 92 of the building is closer to the outdoor side than the shoji 2. Ventilation can be ensured in this section.

The ventilation slats 45 are formed into a plate shape, and a ventilation section 46 is provided between the upper and lower ventilation slats 45. By changing the shape and size of the ventilation slats 45, the interval between the upper and lower ventilation slats 45, etc., the opening area of the ventilation section 46 can be determined, and the amount of ventilation can be adjusted.

A shutter locking device 34 provided on the baseboard portion 31b of the shutter body 31 is locked to the ventilation upper frame 41. A panel locking device 44 provided on the baseboard portion 42b of the ventilation lower frame 42 is locked to the lower frame 12. The state in which the shutter body 31 and the ventilation panel 4 close the outdoor side of the shoji 2 is maintained, and crime prevention can be ensured.

In the shutter-integrated sash device 100, ventilation can be ensured by the ventilation panel 4 attached to the lower side of the shutter body 31 when the shutter body 31 is closed. Since the shutter body 31 is in a closed state, crime prevention is also ensured even if the shoji 2 is open. It is possible to ensure crime prevention that is equivalent to the crime prevention that can be expected when the shutter body 31 is closed when the ventilation panel 4 is not installed.

Since the installation position of the shutter body 31 is the same as when the ventilation panel 4 is not attached, the shutter body 31 can be opened and closed in the same manner as when the ventilation panel 4 is not attached.

Since the ventilation panel 4 is easily removable, it can also be removed, for example, in winter.

The ventilation panel 4 is arranged between the lower end of the baseboard portion 31b of the shutter body 31 and the lower frame 12. The ventilation panel 4 can be installed below the shutter body 31 while utilizing the lower frame 12 of the shutter-integrated sash device 100.
