Description

  The present invention relates to an opening device in a building such as a house having a window screen and a screen door.

In general, some windows in a building have a pair of sliding glass shojis. In such a window, a glass shoji slides in a window frame fitted in a window opening provided in an outer wall portion.
A glass shoji that slides left and right within a window frame is the mainstream, but a type that slides up and down is also known (for example, see Patent Document 1).
JP 2006-241743 A

However, in the conventional sliding type window described above, the glass shoddle moves within the window frame, so that even if the glass shodle is fully opened, only half or less of the area of the window opening can be opened.
In addition, when the window is closed, the screen can be seen through the glass and there is a summoning bowl, so the scenery is impaired when viewing the outdoor scenery from the room. In addition, the screen doors and summoning jars could become shadows during daylighting.

  Therefore, the present invention has been made against the background of the above circumstances, and provides an opening device for a building that improves the feeling of opening and ventilation at the time of opening a window, and that is favorable in daylighting and viewing. Technical issue.

An opening device for a building according to the present invention includes a left and right vertical sash, a window screen supported in the left and right vertical sashes, and an outside or indoor side of the window screen that is supported in the left and right vertical sashes. a screen door that is, the a window sash and the shutter which is supported on the vertical sash of the left and right exterior side of the screen door, the window sash, the window screen and the shutter are vertically movable working independently, the The upper part of the left and right vertical sashes is an opening window part, and the lower part is a storage part formed by an outer wall and an inner wall, and the storage part overlaps the shutter, the window screen and the screen door. The shutter is lifted from the storage portion between the outer wall and the inner wall while being supported by the left and right vertical sashes, and the outer wall surface and the shutter chamber outer surface are moved by the indoor / outdoor moving means when closing the opening window portion. It will be almost the same The features.
Further, here, the indoor / outdoor direction moving means has pins on the left and right side portions of the shutter, the left and right vertical sashes have guide grooves for guiding the pins, and the guide grooves are vertical straight portions. And an example in which an arcuate portion curved toward the outdoor side is provided on the upper portion of the straight portion .
The features of the present invention are as follows.
Left and right vertical sashes (14), a window sash (20) supported in the left and right vertical sashes (14), and the left and right vertical sashes (14) inside or outside the window sash (20). The window screen (30) is supported by the window screen, and the window screen (20) and the screen door (30) are provided so as to be independently slidable vertically along the left and right vertical sashes (14). ) And the screen door (30) can be accommodated between the outer wall (51) and the inner wall (52).

  According to the opening device according to the present invention, the window shoji 20 and the screen door 30 are housed in the wall between the outer wall 51 and the inner wall 52, so that the window opening can be fully opened, and the feeling of opening and ventilation is improved. Also, since the summon bowl is not visible, you can get a full view of the opening. Furthermore, since the summon bowl does not block the light, the daylighting performance is improved.

  Preferably, a shutter (40) supported in the left and right vertical sashes (14) is provided outside the window screen (20) and the screen door (30), and the shutter (40) is provided on the left and right vertical sashes (14). The window shoji (20), the screen door (30), and the shutter (40) can be moved up and down by a driving device (61, 62, 63). (40) overlaps with the window screen (20) and the screen door (30), and it is good to be able to be accommodated between the outer wall (51) and the inner wall (52).

Thus, since it can be opened / closed electrically by the drive device, it can be opened / closed only by a switch operation, so that the opening / closing operation is easy. It can also be opened and closed from a location away from the window.
There is little risk of finger scissors when closing a window like a manual type, and crime prevention is also high. (With manual crescent locking, there is a risk that the window will be opened if the crescent is removed by breaking the window from the outside.) Furthermore, the shutter 40 and the screen door 30 are housed in the wall and only the window screen 20 is used. It is possible to easily perform a daylighting state in which the shutter is closed, or a ventilation state in which only the screen door 30 is closed by storing the shutter 40 and the window screen 20 in the wall.

  Preferably, it is good to set it as the structure provided with the cleaning means (71, 72) which cleans the surface of the outdoor side or indoor side with the sliding movement of the window shoji (20) or the screen door (30) in the up-down direction. By this cleaning means (71, 72), the window screen 20 or screen 30 is automatically cleaned in accordance with the sliding opening / closing operation of the window screen 20 or screen 30, so that it can always be kept clean.

  Preferably, a hollow portion (66) is formed in at least one of the upper and lower horizontal sashes (11, 13) and the left and right vertical sashes (14) positioned at the periphery of the window opening (2). ) As an air-conditioning duct so that air can be blown to the indoor side surface of the window shoji (20). Condensation is likely to occur in the corner portion of the window opening 2 where air convection is stagnant, but air convection can be maintained to the corner by blowing air, so that the dew-proofing property of the glass surface of the window screen 20 is improved. . If an indoor air conditioning system is connected to the intake portion connected to the duct 66, a cold draft caused by the descending cold air generated from the window in winter can be suppressed.

  Preferably, a transparent panel is formed on the outer wall (51) and the inner wall (52). Thus, by making the outer wall 51 and the inner wall 52 transparent, it is possible to obtain a landscape with a large sweep window size together with the window shoji 20 of the window opening 2.

  According to the present invention, the window opening can be fully opened, and a full landscape can be obtained. Moreover, since there is no inner pillar such as a summoning bowl in the window opening, the opening is excellent in appearance and daylighting.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

The shutter 40 is supported in the sash frame 10 and an outer panel 41 and an inner panel 42 are attached to the shutter main frame. The outer panel 41 has the same outer wall tone as the outer wall 51, but may have a slat tone or a decorative glass tone.
A total of four pins, an upper pin 43 and a lower pin 44, are provided on the left and right sides of the shutter 40, and are inserted into the guide grooves 17 formed in the left and right vertical sashes 14.

The window screen 20, the screen door 30, and the shutter 40 are supported by the vertical grooves 15 and 16 and the guide grooves 17 of the left and right vertical sashes 14 so as to be slidable in the vertical direction.
The left and right vertical fences 21 and 31 of the window screen 20 and the screen door 30 are respectively stored in the vertical grooves 15 and 16 of the left and right vertical sashes 14, and are not always visible from the view from the inside and outside of the room.

The upper screen 21 and the lower screen 22 of the window screen 20 are overlapped with the upper sash 11 and the intermediate sash 13 in the expected direction (inside and outside), respectively, so that the window screen 20 is closed. Similarly, the screen door 30 is closed by overlapping the upper sash 31 and the lower sill 32 of the screen door 30 with the upper sash 11 and the intermediate sash 13 in the expected direction (indoor / outdoor direction), respectively.
The window shoji 20 is configured to be openable and closable from a closed state in which the upper collar 21 is in contact with the upper sash 11 to an open state in which the upper collar 21 overlaps the intermediate sash 13. Similarly, the screen door 30 is configured to be openable and closable from a closed state in which the upper ridge 31 contacts the upper sash 11 to an open state in which the upper ridge 21 overlaps the intermediate sash 13.

  As shown in FIGS. 3 and 4, when the window screen 20 is completely closed, the upper, lower, left, and right ridges 21, 22, and 24 of the upper sash 11, the intermediate sash 13, and the left and right vertical sashes 14 are in the prospective direction. And cannot be seen from the view from the indoor side and the outdoor side. Similarly, when the screen door 30 is completely closed, the upper, lower, left, and right ridges 31, 32, and 34 overlap with the upper sash 11, the intermediate sash 13, and the left and right vertical sashes 14, respectively, in the prospective direction. Is not visible from the field of view.

The periphery of the window opening 2 is formed with four laps in the upper half of the upper sash 11, the intermediate sash 13, and the upper half of the left and right vertical sashes 14. On the lower side of the window opening 2, a storage portion 56 is provided between the outer wall 51 and the inner wall 52, and the middle sash 13, the lower sash 12, and the lower halves of the left and right vertical sashes surround the four circumferences.
The window shoji 20, the screen door 30, and the shutter 40 overlap each other in the expected direction and can be completely stored in the storage unit 56 (complete storage pattern). In other words, when the window screen 20, the screen door 30, and the shutter 40 are completely opened, they cannot be seen from the field of view in the expected direction from the indoor side and the outdoor side.

Next, the drive mechanism of the opening device 1 will be described.
As shown in FIG. 1, on the upper sash 11, there are a window shoji 20 driving motor (driving device) 61, a screen door 30 driving motor (driving device) 62, and a shutter 40 driving motor (driving device) 63. is set up.
A sprocket 61b is connected to the window shoji 20 driving motor 61 via a shaft 61a on the left and right. A chain 61c is wound around the sprocket 61b, and the chain 61c is connected to the left and right sides of the window shoji 20 (both ends of the lower rod 22).

A winding drum 62b is connected to the screen door 30 driving motor 62 on the left and right via a shaft 62a. A wire 62c is wound around the take-up drum 62b, and the wire 62c is connected to the left and right sides (upper rod 31) of the screen door 30.
Sprockets 63b are connected to the left and right motors 63 for driving the shutter 40 via shafts 63a. A chain 63c is wound around the sprocket 63b, and the chain 63c is connected to the left and right sides (lower pin 44) of the shutter 40.

  The chains 61c and 63c and the wire 62c are suspended in the hollow cross section of the left and right vertical sashes 14. Therefore, it cannot be seen from the outside in the room from the visual field in the prospective direction. Even if these chains 61c and 63c and the wire 62c are viewed outside the hollow cross section of the left and right vertical sashes 14, there is no functional problem.

  When the shafts 61a, 62a, and 63a are rotated by the drive motors 61, 62, and 63, respectively, the window screen 20, the screen door 30, and the shutter 40 are moved up and down independently. That is, the window screen 20, the screen door 30, and the shutter 40 can be opened and closed independently.

Next, the cleaning function will be described.
FIG. 5 is an enlarged cross-sectional view taken along the line CC of FIG. 1 showing a longitudinal cross-sectional view of the opening device 1, and is a cross-sectional view at the height of the intermediate sash 13.
A wiper 71 as cleaning means is in contact with the outside of the glass 25 of the window screen 20. The wiper 71 on the indoor side of the glass 25 is fixed by sliding into a groove formed in the intermediate sash 13. The wiper 71 on the outdoor side of the glass 25 is slidably fitted into a groove formed in the inner bracket 73 and fixed.

A brush 72 serving as a cleaning unit is in contact with the outside of the net 35 of the screen 30. The brush 72 on the indoor side of the screen door 30 is fixed by sliding into a groove formed in the inner bracket 73. The brush 72 on the outdoor side of the screen door 30 is fixed by sliding into a groove formed in the outer bracket 74.
The inner bracket 73 and the outer bracket 74 are fixed to the vertical sashes 14 on the left and right sides in order on the outdoor side of the intermediate sash 13.

  When the window screen 20 is moved up and down, the wiper 71 is fixed without moving up and down, so that the inner and outer surfaces of the glass 25 are polished by the wiper 71. Similarly, when the screen door 30 is moved up and down, the brush 72 is fixed without moving up and down, so that the inner and outer surfaces of the net 35 are polished by the brush 72. Thus, the inner and outer surfaces of the glass 25 and the inner and outer surfaces of the net 35 of the screen door 30 are automatically cleaned.

Next, the dew proof / air blowing function will be described.
FIG. 6 is an explanatory diagram showing an outline of the air blowing function of the opening device 1, FIG. 6 (a) is a schematic perspective view, and FIGS. 6 (b), (c), and (d) are FIG. ) Is a cross-sectional view of the upper sash 11, the intermediate sash 13, and the vertical sash 14.
A fan 65 as a blower is disposed on the upper sash 11.
A hollow portion 66 as an air conditioning duct is formed in the upper sash 11, the intermediate sash 13, and the left and right vertical sashes 14 positioned at the periphery of the window opening 2.

  The hollow portions 66 of the upper sash 11 and the intermediate sash 13 are connected to the hollow portions 66 of the vertical sash 14 through holes formed on the inner side surfaces of the left and right vertical sashes 14 (the abutting surfaces of the upper sash 11 and the intermediate sash 13). It is connected. Packing is sandwiched between the left and right ends of the upper sash 11 and the intermediate sash 13 and the contact surfaces of the left and right vertical sashes 14, and the periphery of the hole formed in the side surface of the vertical sash 14 is sealed.

By blowing air with a fan 65 from a hole formed in the upper surface of the upper sash 11, air (air) flows into the connected hollow portion (duct 66). Air is discharged from a discharge port (hole) 67 formed in the upper sash 11 and the intermediate sash 13.
Since air can be blown to the indoor side surface of the window screen 20, dew condensation is prevented by expelling air around the corner where air convection is likely to stagnate to promote air convection.

The opening device 1 according to the present invention configured as described above has the following effects.
Since the window shoji 20, the screen door 30, and the shutter 40 are housed in the wall (the housing portion 56) between the outer wall 51 and the inner wall 52, the window opening 2 can be fully opened, and the feeling of opening and ventilation is improved. . Moreover, although the summoning candy crosses the center part of the window opening in the conventional sliding window, since the summoning candy is not visible in the present invention, a full landscape view of the opening can be obtained. That is, a wide and wide view having a width of 1.5 m or more and a height of 1 m or more can be obtained in a state where there is no blocking of the pillars and the like.
Furthermore, since there is no light blocking by the summon bowl, the lighting performance is improved without shadows such as pillars appearing on the floor.

Further, since the window screen 20, the screen door 30, and the shutter 40 can be electrically opened / closed by the driving devices 61, 62, 63, the opening / closing operation is easy because they can be opened / closed only by a switch operation. It can also be opened and closed from a location away from the window.
There is little risk of finger scissors when closing a window like a manual type, and crime prevention is also high. (With manual crescent locking, if the crescent is removed by breaking the window from the outside, the window may be opened.)
Furthermore, the window screen 20, the screen door 30, and the shutter 40 are fully opened (fully open mode), and the shutter 40 and screen 30 are housed in the storage unit 56 in the wall and only the window screen 20 is closed (lighting). Mode) or a ventilation state (ventilation mode) in which the shutter 40 and the window screen 20 are housed in the housing 56 in the wall and only the screen door 30 is closed.

The wiper 71 as the cleaning means automatically cleans the glass 25 of the window screen 20 while being sandwiched from inside and outside the room as the sliding screen 20 is opened and closed, so that it can always be kept clean. Moreover, the brush 72 as a cleaning means is automatically cleaned while the net 35 of the screen door 30 is sandwiched from inside and outside the room as the screen 30 is slid open / closed, so that it can always be kept clean.
Further, the wiper 71 and the brush 72 can prevent dust and dirt from entering the storage portion 56.

Condensation is likely to occur at the corner of the window opening 2 where air convection is stagnant. However, since air convection can be maintained to the corner by blowing air, dew prevention on the surface of the glass 25 of the window screen 20 is performed. Improves.
The air-conditioning duct installed on the ceiling on the house side (usually a lot of elongated or circular air vents on the ceiling, but poor in appearance) is abolished, and the air duct on the house side is replaced with the duct of the present invention. If it connects with the intake part connected to 66, a window will become a ventilation port of an air conditioning. As a result, the indoor landscape of the ceiling is improved, and the thermal draft from the window (feeling cold from the window in winter: cold draft, feeling hot from the window in summer: heat draft) can be suppressed.

Further, since the shutter 40 is an integrated type (one panel type that does not deform even when it is closed), it is difficult to be destroyed even if it is attacked from the outdoor side for crime prevention. In particular, since the shutter 40 is a top-open type, even when the shutter 40 is half open, it is difficult to enter from the outside because the high part is open. That is, in this embodiment, the upper end of the window opening 2 is 2 m or more from the indoor floor, and 2.2 m or more from the outdoor road surface, and the crime prevention performance is improved.
When the conventional bottom-open type shutter is dropped, a hand may be caught between the floor surface and an injury may occur, but since it is an upper-opening, it is difficult for the hand to be caught when the shutter 40 is closed.
Furthermore, when it is used in a half-open state, it can be ventilated with good privacy and can be used for daylighting.

Moreover, since drive parts, such as motor 61, 62, 63, are provided between the outer wall 51 and the inner wall 52, it does not protrude from a wall and it looks good.
Since these drive units are disposed on the window opening 2 (upper sash 11), the drive unit can be prevented from being broken by water, dust, fallen leaves, and the like.

[Example 2]
Next, the opening part apparatus 101 of Example 2 is demonstrated. The basic configuration of the opening device 101 of the second embodiment is the same as that of the opening device 1 of the first embodiment. The second embodiment is greatly different from the first embodiment described above in that the shutter 140 is closed and is flush with the outer wall 51 (flat).
FIG. 7 is a longitudinal sectional view of the opening device 101 and FIG. 4 is a longitudinal sectional view of the first embodiment.
(Corresponding to BB enlarged sectional view of FIG. 1). In addition, the same code | symbol as Example 1 is attached | subjected about the same structure as the above-mentioned structure in the present Example 2. FIG. In addition, the second embodiment is a modification of the first embodiment, and the operations and effects obtained for the same parts as the configuration of the first embodiment are the same. (The same applies to Examples 3 and after.)

FIG. 8 is a schematic diagram schematically illustrating the opening / closing operation of the shutter 140 in the opening device 101 according to the second embodiment, and is a vertical cross-sectional view illustrating a DD cross section of FIG. 1. 8A shows the fully closed state of the shutter 140, FIG. 8B shows the half-opened state with the upper side slightly opened, and FIG. 8C shows the fully closed state.
The configuration of the shutter 140 is not significantly different from that of the first embodiment, and the left and right sides of the shutter 140 are provided with a total of four pins, an upper pin 143 and a lower pin 144, formed on the left and right vertical sashes 14. The guide grooves 117 and 118 are inserted.

As shown in FIG. 8, the left and right vertical sashes 14 are formed with two guide grooves 117 and 118 on the upper and lower sides. The upper and lower guide grooves 117 and 118 are straight portions formed from the lower end to the middle portion in parallel with the vertical direction, and are arcuately curved toward the outdoor side toward the upper end.
The upper end of the lower guide groove 118 is configured to be above the lower end of the upper guide groove 117 in the vertical direction.

When the shaft 61a rotates from the fully closed state of the shutter 140 as shown in FIG. 8A by the drive of the drive motor 63 as in the first embodiment, the shutter 140 rises. The shutter 140 slides vertically for a while along the straight portions of the upper and lower guide grooves 117 and 118. When the upper pin 143 and the lower pin 144 come to the curved portions at the upper ends of the guide grooves 117 and 118, they are guided by the curved portions, and as shown in FIGS. 8B and 8C, the shutter 140 is raised. While moving in the outdoor direction.
That is, when it is lifted upward, an offset operation is performed along the upper and lower guide grooves 117 and 118, and the peripheral outer wall 51 and the shutter chamber outer surface 141 are flush with each other (fully closed state).

The design of the outdoor surface 141 of the shutter 140 can have various variations such as decorative glass tone and slat tone, but by using the same outer wall tone as the peripheral outer wall 51, the field of view from the outdoor side in the fully closed state Therefore, a sense of unity can be obtained. In other words, the design is improved, and it becomes difficult to notice that there is a window at first glance.
When the shutter 140 is lowered to the lower side, it is offset along the guide grooves 117 and 118, and is stored in the wall (storage portion 56) while being moved indoors (fully opened state).

As shown in FIG. 7, a light source 181 such as a fluorescent lamp may be provided on the indoor upper side (upper sash 11) of the shutter 140.
At night, when the shutter 140 is fully closed, when the light source 181 is turned on, the interior surface (inner panel) 142 of the shutter 140 is reflected as a reflection surface, and the window is opened in an atmosphere like daylighting. 2 can be illuminated. Since the building was originally designed to be daylighted from the window, it can be used as a lighting function.
If a photograph of a landscape or a design image is pasted on the interior surface 142 of the shutter 140, a design view can be obtained from the window opening 2 even when the shutter 140 is closed. At this time, it is preferable that the window screen 20 is also raised and closed, and only the screen door 30 is lowered and stored.

[Example 3]
Next, the opening device 201 of Example 3 will be described. The opening device 201 of the third embodiment is greatly different from the above-described embodiment in that the opening device 201 itself functions as a door.
FIG. 9 is a perspective view of the opening device 201 according to the third embodiment. FIG. 9A shows a fully open state, and FIG. 9B shows a state where the shutter 40 is half open. In both cases, the window screen 20 and the screen door 30 are fully opened.
As shown in FIG. 9, the opening part apparatus 201 (sash frame 10) is a door of the entrance / exit. However, when the door is closed, it functions in the same manner as a building wall as in the above-described embodiment.

In the opening device 201, a driving device 263 for the shutter 40 as shown in FIG. 10 is provided on the lower side (housing portion 56). Although not shown, drive devices 261 and 262 for the window screen 20 and the screen door 30 are also provided in the same manner.
Thus, since it has a drive part in a wall, it does not protrude from a wall and it looks good. Furthermore, since the drive unit is disposed under the window opening 2, the upper space of the window opening 2 (upper sash 11) can be made compact as much as possible, and the appearance is good.
You may apply not only to an opening door as shown in FIG. 9, but to a sliding door (door).

[Example 4]
Next, the opening device 301 of Example 4 will be described. In the opening device 301 of the fourth embodiment, the outer wall 51 and the inner wall 52 of the storage portion 56 in the first embodiment are made transparent. At this time, neither the reinforcing member 53 nor the waterproof plate 55 is used (the inner wall 52 has a waterproof function).
Thus, a landscape with a large sweep window size can be obtained simply by vitrifying the waist wall (the outer wall 51 and the inner wall 52 of the storage portion 56).

The specific configuration of the present invention is not limited to the above-described embodiment, and can be variously changed, and the same effect as that of the above-described embodiment can be obtained.
In the above-described embodiment, the window screen 20, the screen door 30, and the shutter 40 are moved up and down, but the shutter 40 may not be attached.
In the embodiment described above, the window shoji 20 and the screen door 30 are completely stored in the storage portion 56 between the outer wall 51 and the inner wall 52 (complete storage pattern), but the length in the vertical direction is longer than the storage portion 56 from the window opening 2. It is good also as a partial storage pattern which cannot be stored in the range covered with the walls 51 and 52 and the upper end of the window screen 20 or the screen door 30 is partially left behind.
