Description

[Detailed description of the invention] This invention relates to a window device.

Some conventional sliding door type window devices are designed to ventilate the room using a gap provided above the sliding door while the sliding door remains closed. 1st
Figures 3 to 3 show such a conventional window device, in which a ventilation hole 3 is provided on the indoor side of the upper frame 2 of a glass sliding door 1 so that it can be opened and closed by a sliding device 4, and the upper frame 2 A slit 5 is provided on the outdoor side of the room, and the room is ventilated using the slit 5 and the ventilation hole 3. 6 is an opening frame.

However, the slit 5 on the outdoor side cannot be formed large to prevent rainwater from entering.
Moreover, since the ventilation path is bent by the water cut-off 6', there is a problem in that the amount of ventilation is reduced and the ventilation performance is poor.

Therefore, an object of the present invention is to provide a window device that allows ventilation with the window closed, has excellent ventilation performance, and can also keep the room airtight when ventilation is not required.

An embodiment of the present invention will be described with reference to FIGS. 4 to 9. That is, as shown in FIG. 4, this window device has U-shaped rail engaging members 9 at both ends of the upper frame 8 of the sliding door main body 7 so as to be retractable from the upper end surface thereof.
At the same time, the door roller 11 is attached to the lower frame 10 of the sliding door main body 7 so as to be able to rise and fall freely, and the rail engaging member 9 and the door roller 11 are simultaneously moved by rotating the operating lever 13 pivotally connected to the indoor side of the vertical frame 12. It can be driven up and down.

FIG. 5 shows a schematic diagram of the drive mechanism, and the solid line in the figure shows the state when the operating lever 13 is in the vertical position as shown in FIG. 4, and the imaginary line in FIG. 4 shows the state when the operating lever 13 in FIG. 4 is rotated 90 degrees clockwise. That is, when the operating lever 13 is rotated 90 degrees, the cam 14 rotates 90 degrees clockwise about the shaft 15, and the elevating rod 16 follows the first cam surface 14a to move the left rail engaging member 9. raise. Further, the lifting rod 18 biased upward by the compression spring 17 moves up following the second cam surface 14b, the first link 19 rotates clockwise about the shaft 20, and the second The link 21 rotates counterclockwise about the shaft 22 to raise the left door wheel 11. As the left door roller 11 rises, the right door roller 11 also rises via the third link 23. Furthermore, the fourth link 24 rotates clockwise about the shaft 25, and the fifth
The link 26 rotates counterclockwise about the shaft 27, and the elevating rod 28 rises to engage the right rail engaging member 9.
make it stand out. When the operating lever 13 is returned to its original position, the door roller 11 and the rail engaging member 9 are moved in the opposite manner to the above.
each descends.

The sliding door body 7 is attached to an opening frame 29 made of aluminum sash, as shown in FIGS. 6 to 9. That is, as shown in FIGS. 6 and 7, with the rail engaging member 9 and the door roller 11 in the lowered position, the upper rail 31 is inserted into the upper groove 30 of the sliding door body 7, and the door roller 11 is inserted. Place the sliding door body 7 on the lower rail 32, and attach it to both rails 31,
Install it so that it can slide freely along 32. In this state, the space between both rails 31 and 32 is closed by the sliding door body 7. Next, as shown in FIGS. 8 and 9, if the operating lever 13 is rotated to drive the door wheel 11 and the rail engaging member 9 upward, the sliding door body 7
The chisel is lowered to form a ventilation slit 33 between the upper end of the sliding door body 7 and the sliding door rail 31. In this case, since the rail engaging member 9 continues to grip the upper rail 31, the sliding door main body 7 does not fall.

As a result of this configuration, when the sliding door main body 7 is closed and the sliding door main body 7 is lowered by the operation lever 13 as shown in FIGS. 8 and 9, the sliding door main body 7
Since a ventilation slit 33 is formed between the upper end and the upper rail 31, it is possible to ventilate the room with the window closed. Moreover, since the ventilation slit 33 spans the entire width of the sliding door body 7, the ventilation area is wide, and the ventilation path is straight without bending, so pressure loss is reduced and the ventilation effect is large. Furthermore, since the ventilation slit 33 is formed in the upper part of the window device, the ventilation efficiency is also good. In addition, when ventilation is not required,
As shown in FIG. 7 and FIG. 7, the opening frame 29 can be completely closed by the sliding door body 7 by returning the operating lever 13 to its original position, so that the airtightness is also high.

As described above, the window device of the present invention includes an opening frame in which an upper frame member and a lower frame member are provided with an upper rail and a lower rail extending in the longitudinal direction of the frame member, and a rail engagement member slidably engaged with the upper rail. A coupling member, a door roller slidably engaged with the lower rail, and a door roller that is held movably up and down by the rail engagement member and the door roller, and closes the space between the upper rail and the lower rail in the raised position, and closes the gap between the upper and lower rails in the lowered position. Since it includes a sliding door body that forms a ventilation slit between the upper end and the upper rail, an operating member attached to the sliding door main body, and a drive mechanism that drives the sliding door body up and down in conjunction with the operation of the operating member, Ventilation is possible with the windows closed, which has excellent ventilation performance, and also has the effect of keeping the room airtight when ventilation is not required.
