Description

[Detailed Description of the Invention] (Technical Field) The present invention relates to an opening/closing device for an air circulation shutter provided in the upper frame of a window equipped with a sliding door type shoji and the lower stile of the shoji.

(Prior Art) Solar heating windows have traditionally been considered as windows that can be opened and closed to open and close indoors and outdoors. In other words, in this type of window, blinds that collect solar heat are installed in the double window space, the heat collected by the blinds heats the air in the space, and the heated air is further heated. In order to bring the air into the room, a window has been put into practical use in which air vents with shutters are formed at the top and bottom of the window on the indoor side.

In buildings such as detached houses and apartment complexes to which such windows are applied, there is usually a balcony on the south side exposed to solar heat rays, so a sliding door is required to access the balcony. Furthermore, even if there were no entrances or exits, sliding doors were required to ventilate indoor air to the outdoors.

On the other hand, for windows (indoor windows), in order to maximize the lighting area of the window, the upper air circulation opening is formed in the upper frame, and the lower air circulation opening is formed in the lower stile of the internal shoji.
An upper shutter and a lower shutter are provided respectively. However, the upper shutter was located relatively high and was difficult to reach, making it difficult to open and close it.
In addition, since the lower shutters were located on both the left and right shoji screens, it was difficult to open and close all the shutters.

(Purpose of the invention) The purpose of the invention is to provide a shutter opening/closing device for the above-mentioned window in which the shutter provided on the upper frame and the shutter provided on the sliding door type shoji can be opened and closed in conjunction with each other.

(Structure of the invention) The above object is to form an opening that communicates indoors and outdoors in the upper frame of a window with a sliding door type shoji and the lower stile of the inner and outer shoji of the sliding door type shoji, and to open and close the openings respectively. A shutter is provided, and the inner stile of the sliding door type shoji has a rotatable handle,
A first rod is provided that is movable upward within the inner matching frame in conjunction with the rotation of the handle, and a second rod that is movable downward within the outer matching frame is provided on the outer matching frame. A pointed pin is formed at the upper part of each of the first and second rods, and a rack block is formed at the lower part to mesh with a pinion fixed to the shutter rotation shaft of the inner and outer shoji. The upper frame includes a first actuating block that is movable upward and has a rack portion at one end and a pointed pin receiving portion at the lower end, and a first actuating block that engages with the rack portion and is fixed to the rotating shaft of the shutter of the upper frame. a second actuating block having a pointed pin receiving portion at its lower end and movable downward in conjunction with the upward movement of the first actuating block; When the shoji block is closed, both operating blocks move to the first position of the inner and outer shoji.
This is achieved by a shutter opening/closing device for a sliding door type window, which is disposed on the upper frame at a position vertically aligned with the axis of the second rod.

(Example) Hereinafter, an example of the present invention will be described using a solar heat utilization window as an example.

In the opening of the building frame, an indoor window 4 is provided, in which a sliding shoji 4a is fitted in a rectangular window frame assembled with an upper frame 1a, a vertical frame 2a, and a lower frame 3a. On the outside, there is an upper frame 1b, a vertical frame 2b, and a lower frame 3b.
An outdoor window 5 with a sliding door type shoji 5a fitted inside the rectangular window frame assembled in is provided, and a space 6 between both windows is provided.

The above-mentioned blind 7 consists of a group of slats arranged in parallel vertically at regular intervals, and the slat group includes, for example, a first slat 8 having a solar heat absorbing surface on its upper surface and a second slat 8 having a solar heat reflecting surface on its upper surface. The slats 9 are arranged alternately. A lifting cord (not shown) is provided to connect only one of the slats, and in winter, when the first slat 8 is stacked on the second slat 9, the upper surface of all the slats becomes a heat absorbing surface. and the above space 6
Effectively heats the air inside. On the other hand, during the summer, the second
When the slats 9 are superimposed on the first slats 8, the upper surfaces of all the slats become only heat reflecting surfaces, and solar heat rays can be reflected toward the outdoors.

In order to effectively utilize the air heated by the solar heat collection blind 7 in the space 6 for indoor heating, the upper frame 1a of the indoor window 4 and the indoor shoji 4
An upper opening 10 and a lower opening 11 are formed in the lower stile a, and an upper shutter 12 of the present invention is formed in each opening.
and a lower shutter 13. Shutter 1
2 and 13 are formed in a hinge shape attached to a rotating shaft 14, and a gasket 15 made of sponge or the like is provided around the four circumferences of the openings 10 and 11 (FIG. 2).

Inner sliding frame 16 of inner shoji of shoji 4a (Fig. 1)
In addition to the usual crescent-shaped locking device 17, a handle 18 is provided which serves both to open and close the shutter and to lock it. The opening and closing mechanism of the shutter will be explained with reference to FIGS. 4 and 5. Note that the usual locking tool 17 is omitted in FIGS. 4 and 5. The handle 18 is a shoji 4a
The pawl 1 that engages with the inner shoji and the handle 18
The receiver having 9 is attached to the outer shoji.
Eccentric pin 20 fixed eccentrically to the handle 18
is the guide block 21 installed inside the inner door frame.
It is slidably fitted into a guide groove 22 formed in. At the upper and lower ends of the guide block 21, there are respectively an upper rod 23 and a lower rod 24 (in this embodiment, both rods are formed in a plate shape and are provided within the inner alignment frame) so that they can be adjusted in the length direction. Tighten the bolts.

A rack block 26 is loosely connected to the lower end of the lower rod 24 via a connecting pin 25. The connecting pin 25 is loosely fitted into the elongated hole of the lower rod 24 with a vertical play of length h. A pinion 27 is provided at one end of the rotating shaft 14 of the lower shutter 13 of the inner shoji, and the pinion and the rack block 2
Engage the 6 racks. Further, a pointed pin 28 is provided at the upper end of the upper rod 23. This pointed pin is formed so as to be able to protrude above the upper edge of the inner shoji.

As shown in FIG. 4, there is a long plate-shaped rod 23a inside the outer shoji frame (not shown) of the shoji 4a.
is provided so as to be movable downward, and at the lower end of the rod 23a there is a rack block 2, similar to the case of the inner shoji.
6 is connected. Lower shutter of outer shoji 1
A pinion 27 is provided at one end of the rotating shaft 14 of No. 3, and is engaged with the rack of the rack block 26. Further, a pointed pin 28a is provided at the upper end of the rod 23a. Unlike the inner shoji rod, the outer shoji rod is not provided with an adjustment part such as the guide block 21, so the pointed pin 28a is fixed by sandwiching the washer 28b in a stacked manner and screwing it into the upper end of the rod 23a. Adjust the length in the direction by adjusting the thickness of the washer. It is also advantageous to provide the rod 23a with a spring 23b that biases it upward, since the rod will generate a restoring force after actuation.

On the other hand, a casing 29 is fixed within the upper frame 1a, and a first actuating block 30 is provided inside the casing 29 so as to be slidable in the vertical direction. The actuation block 30 includes a rack portion 30A projecting upward and a pointed pin receiving portion 30B projecting downward from the bottom of the upper frame. The above-mentioned actuation block 30 is provided at a position vertically aligned with the pointed pin 28 when the indoor shoji 4a is closed, and a predetermined gap H is provided between the lower end of the actuating block 30 and the upper end of the pointed pin. There is. This gap H is provided to prevent the pointed pin 28 from colliding with the operating block 30 when the indoor shoji 4a is opened and closed, and has a length approximately equal to the above-mentioned play h. Both upper shutters 12 in the upper frame 1 are connected to each other by a rotating shaft 14, and a pinion 31 is fixed in the middle of the rotating shaft.
meshes with the rack portion 30A of the actuating block 30. Note that the play h can be eliminated by making the pinion 27 relatively large in diameter.

A second actuating block 32 is provided inside the casing 29 so as to be slidable vertically.
The actuating block 32 has a protrusion 32A that protrudes upward.
and a pointed pin receiving part 3 protruding downward from the bottom of the upper frame.
2B. Like the first actuating block 30, this actuating block 32 also vertically aligns with the pointed pin 28a with a gap H when the indoor shoji 4a is closed. A spring 33 is provided within the casing 29 to urge the actuating block 32 upward.

The portion 29a of the casing 29 between the above-mentioned two operating blocks is used as a rotational fulcrum, and both ends are connected to the rack portions 3, respectively.
Interlocking lever 34 pivotally connected to 0A and protrusion 32A
will be established. Preferably, the lever ratio X:Y of the interlocking lever 34 is 2:1. Although the lever-type interlocking mechanism between the first and second actuating blocks has been described, the interlocking mechanism between the first and second actuating blocks may be a gear-based interlocking mechanism.

Next, the operation of the present invention will be explained. When the space 6 is used as a heat collecting space, the upper and lower shutters 12 and 13 are opened only when the indoor shoji 4a is closed. When the indoor shoji 4a is closed and the handle 18 is rotated, the eccentric pin 20 fixed to the handle 18 inside the inner shoji is rotated and the guide block 21 is moved. Therefore, the upper rod 23
and lift the lower rod 24 upward.

Filling the gap H, the pointed pin 28 moves upward and abuts against the receiving part 30B of the first actuating block 30,
When it rises further and pushes up the actuating block 30, the actuating block 31 is rotated by the rack portion 30A and the left and right upper shutters 12 are opened. The lower rod 24 is also lifted with the upper rod 23, but the rack block 26 is not raised until the lower rod 24 has moved by the play length h. Rack・
When the block 26 starts to rise, the pinion 27 is rotated by the rack. The lower shutter 13 provided within the inner sash is opened by rotation of a pinion 27 meshed with a rack block 26.

When the first actuating block 30 is raised, the second actuating block 32 is lowered via the interlocking lever 34, and the pointed pin receiving part 32B is attached to the rod 23 of the outer shoji.
Press a down. Accordingly, the rack block 26 is lowered and the lower shutter 13 of the outer shoji is also opened.

When the handle 18 is returned to its original position, the pinions 31 and 27 are rotated in opposite directions by the racks 30A and 26, and the upper shutter 12 and the lower shutter 13 of the inner sash assume the closed position. In this case, the upper shutter is closed by the dead weight of the first actuating block 30. When the weight of the actuating block 30 is relatively small, it is advantageous to provide a spring between the casing 29 and the actuating block 30 to bias the block downward.

Together with this, the second actuating block 32 is activated by a spring 33.
As a result, the rod 23a is returned to its original state by the spring 23b, and the lower shutter 13 of the outer shoji is closed.

The locking tool 17 is used for locking the shutter when the shutter is closed during sunshine in winter or the like.

(Effects of the invention) Since the present invention is configured as described above, the upper shutter provided on the upper frame and the lower shutter provided on the inner and outer shoji are brought together by the handle provided on the inner and outer stile when the inner and outer shoji are closed. It can be opened and closed by movement.
