-Configuration of natural ventilation window-
A natural ventilation window according to an embodiment of the present invention will be described with reference to FIG.
(Whole configuration)
As shown in FIG. 1, the natural ventilation window of the present embodiment is installed at the building opening, upper frame 11, lower frame 12, left, right vertical frames 13, 14, and upper frame 11 and lower frame 12. And a vertical frame 15 erected substantially at the center in the left-right direction, and a window frame 1 having openings at the left and right of the vertical bone 15, an upper ridge 21, a lower ridge 22, and left and right vertical ridges A pair of panels 23 and 24 is formed into four, and panels made of glass or the like are fitted on the inner periphery thereof.
The shoji 2 and 2 are pivotally supported at a position above the middle height between the left and right vertical frames 13 and 14 and the vertical bone 15, respectively, and a weight 26 is provided on the indoor side at a position above the pivotal point.
The open / close arm 4 for controlling the open / close state of the shoji 2 and the restriction arm 5 for regulating the open / close angle of the shoji 2 are disposed on both sides of the longitudinal bone 15, and by operating the operation means 4b The opening / closing arm 4 can be driven to operate the opening / closing of the shoji 2 or 2.

(Opening and closing operations of Shoji
The opening and closing operation of the shoji 2 will be described with reference to FIGS. 2 to 4.
The shoji 2 is rotatably supported by the support shaft 2a at a position higher than the middle height of the shoji 2 with respect to the window frame 1, and the upper frame 21 relative to the upper frame 11 is the lower frame from the indoor side. The lower frame 22 is configured to be close to the side 12 from the outdoor side. Then, due to the balance between the force of the wind and the weight 26 provided at the upper position of the shoji 2, it naturally opens and closes centering on the support shaft 2 a.

The open / close arm 4 has an upper arm portion 41 and a lower arm portion 42 connected at a predetermined angle (about 135 degrees), and the connection point of both arm portions is substantially the same height as the support shaft 2a of the shoji 2 It is pivotally supported by a rotating shaft 4 a projecting from the vertical bone 15. An upper roller 43 and a lower roller 44 made of, for example, a material such as rubber are rotatably supported at the ends of both arm portions, and the upper roller 43 and the lower roller 44 are rotated by the opening and closing arm 4. It is comprised so that the vertical weirs 23 and 23 may be contact | abutted from indoor side.
The restricting arm 5 is pivotally supported by the restricting arm pivoting shaft 5 a protruding slightly from the vertical bone 15 at a position slightly above the pivoting shaft 4 a of the opening / closing arm 4. There is a stopper surface 5b that abuts the indoor side surface to regulate the opening / closing angle of the shoji 2 and normally, the rotation control is performed such that the stopper surface 5b is at an initial position that does not regulate opening / closing of the shoji 2 at all. .
Then, according to the outdoor conditions, specifically, when there is rainfall, when the air temperature is lower than the predetermined temperature, and when the humidity is higher than the predetermined humidity, the power is generated without using any driving force such as electric power. By the operation of the restricting member driving means 6, the stopper surface 5b is controlled to turn to a restricting position which restricts the maximum opening / closing angle of the shoji 2 to a predetermined angle or less.

FIG. 2 shows a state in which the opening and closing arm 4 maintains the closing of the shoji 2.
The open / close arm 4 is pivoted to a position where the upper roller 43 abuts the indoor side of the longitudinal ribs 23, 23 of the longitudinal bone 15 side of the shoji 2 about the pivot shaft 4a by the operation of the operation means 4b. The upper roller 43 abuts against the longitudinal ridges 23, 23 at a position higher than the support shaft 2a of the shoji 2 to prevent the upper roller 43 from opening the support shaft 2a of the shoji 2 and maintain the closed state. It will be done.
In addition, the restriction arm 5 is not linked at all with the rotation of the open / close arm 4, and the stopper surface 5b is in an initial position at which the opening / closing of the shoji 2 is not restricted at all.

FIG. 3 shows a state in which both the opening and closing arm 4 and the restriction arm 5 allow opening and closing of the shoji 2 in the entire opening and closing range.
The open / close arm 4 is pivoted so that the lower arm portion 42 becomes substantially vertical centering on the pivot shaft 4 a by the operation of the operation means 4 b and the upper arm portion 41 extends obliquely upward in the indoor direction. Both the rollers 44 are retracted to positions where they do not interfere with the opening / closing operation of the shoji 2. Note that, by rotating the open / close arm 4 so that the lower arm portion 42 moves to the outdoor side from this state, the shoji 2 can be forcibly maintained in the open state.
Since the restriction arm 5 is not in the state of restricting the maximum opening and closing angle of the shoji 2 in the outdoor situation, the restriction arm 5 is maintained at the initial position which does not affect the opening and closing of the shoji 2 at all.
Thereby, the shoji 2 is allowed to open until the longitudinal ridges 23, 23 on the longitudinal bone 15 side contact the upper roller 43 centering on the support shaft 2a, and the wind force and the weight 26 It can be opened and closed naturally by the balance.

FIG. 4 shows a state in which the maximum opening / closing angle of the shoji 2 is restricted by the restriction arm 5.
The open / close arm 4 is turned so that the lower arm portion 42 becomes substantially vertical centering on the rotational shaft 4 a by the operation of the operation means 4 b and the upper arm portion 41 extends upward in the indoor direction. Are both retracted to positions where they do not interfere with the opening / closing operation of the shoji 2.
On the other hand, the restricting arm 5 abuts against the indoor side surface of the vertical rod 23 of the shoji 2 with the stopper surface 5b centered on the restricting arm rotation shaft 5a by the function of the restricting member driving means 6 operated according to the outdoor situation. The rotation control is performed so as to be a restriction position in which the open / close angle is restricted to a predetermined angle or less.
Therefore, the opening and closing of the shoji 2 is not restricted at all by the open / close arm 4, but the maximum open angle shown in FIG. 4 is obtained by contacting the stopper surface 5b of the restriction arm 5 at the restriction position (for example, 5 to 10 degrees) ) Are regulated. Therefore, the shoji 2 can be opened and closed naturally by the balance of the force of the wind and the weight 26 in the range of the closed state shown in FIG. 2 and the restricted open state shown in FIG.

As described above, the natural ventilation window according to the embodiment of the present invention is the open / close arm 4 that performs the open / close control from the closed state to the open state of the shoji 2 and the restriction that regulates the maximum open / close angle of the shoji according to the outdoor situation. Even if arm 5 is individually provided and opening / closing control of shoji 2 is performed by opening / closing arm 4 and opening / closing is permitted in the entire opening / closing range, for example, when rainfall occurs, the function of restriction arm 5 The maximum opening angle is regulated to such an extent that rainfall does not fall, and it is possible to prevent rain and to continue natural ventilation.
In addition, the rotation control of the restriction arm 5 is performed by the function of the restriction member drive means 6 that generates power by using, for example, no rainfall or any driving force such as electric power according to the outdoor situation. It is possible to automatically perform the open regulation control by the regulation arm 5 without any influence on the drive control of the open / close arm 4 without requiring the wiring and the like necessary for the control drive system.

(Configuration of restricting member driving means)
The configuration of the restricting member driving means 6 will be described with reference to FIGS.
The restricting member driving means 6 is fixed to the frame member 61 in a plan view U-shape, the gear unit 62 fixed to the upper portion of the frame member 61, and the restricting arms 5 and 5 projecting from both side surfaces. It comprises an interlocking bar 63 supported movably up and down, and a power generating means 64 for vertically driving the interlocking bar 63, and the inside of the longitudinal bone 15 with the restriction arms 5, 5 projecting from the side surface of the longitudinal bone 15. Is located in

The power generation means 64 generates power without using any power source such as electric power by expanding and contracting under outdoor conditions, and is arranged outside the lower position of the frame member 61 and interlocking bar 63 is driven in the vertical direction.

  As shown in FIG. 6, the interlocking bar 63 is vertically movably supported on the frame member 61 by guide members 63a and 63b provided at the upper and lower portions of the frame member 61 or the vertical bone 15, and is biased. It is lightly biased upward by a means (not shown), and power transmission teeth 631 are formed at the upper end, and a power reception portion 632 for receiving the power generated by the power generation means 64 is provided at the lower end thereof. There is. Further, the interlocking bar 63 has an impact absorbing portion 63c at an intermediate portion thereof, and when the shoji 2 is rapidly opened and abuts against the regulating arm 5, the impact transmitted to the interlocking bar 63 is By separating up and down against the biasing means, it is prevented that the rain detection tape 648a described later is broken.

  The gear unit 62 having the restricting arm 5 is configured by housing gears 621, 622, and 623 for transmitting the power from the power transmission teeth 631 of the interlocking bar 63 to the restricting arm 5 in the case, as shown in FIG. The gear 621 meshes with the power transmission teeth 631 of the interlocking bar 63. Then, by setting the rotation shaft of the gear 623 to the restriction arm rotation shaft 5 a of the restriction arm 5, the vertical movement of the interlocking bar 63 transmitted by the power transmission teeth 631 is transmitted as the rotational force to the restriction arm 5. There is.

(Configuration of power generation means)
The motive power generation means 64 for driving the interlocking bar 63 up and down is composed of a unit whose property is changed due to the change of outdoor temperature or the change of humidity (such as the adhesion of water) without using any motive power source such as electric power. The thermal element unit 641 includes a thermal element 643 that shrinks due to a decrease in temperature, and the tape unit 646 includes a tape element 648 that extends by detecting rainfall (water content).

The thermo element unit (drive means) 641 is supported by upper and lower two holding members 641 a and 641 b fixed to the outdoor side surface of the plate member 64 a supported on the outside of the lower end chamber of the frame member 61 and a lower holding member 641 b It is supported by a thermo element 643 for causing the blocking shaft 643 a to project upward from the lower holding member 641 b and an upper holding member 641 a to press the power receiving portion 632 of the interlocking bar 63 downward from above with a spring or the like. It comprises the upper output part (biasing means) 642.
The blocking shaft 643a of the thermoelement 643 vertically penetrates the power receiving portion 632 provided at the lower end of the interlocking bar 63 from below, and the upper end of the blocking shaft 643a penetrates the upper output portion (biasing means) 642 The lower end is supported to prevent the transmission of the pressing force to the power receiving portion 632 by the upper output portion (biasing means) 642.
The thermo element 643 contains a wax which solidifies due to a temperature change, for example, when the temperature changes from 18 ° C. to 10 ° C., the wax solidifies and the volume shrinks, and the blocking shaft 643 a is located below Lowers by about 10 mm, allowing the pressure (biasing force) from the upper output part 642 to be transmitted to the power receiving part 632 to generate a driving force, and the power receiving part 632 and the interlocking bar 63 about 10 mm Let down.

The tape unit (drive means) 646 comprises a tape support member 647 supported by the frame member 61 and the gear unit 62 fixed to the frame member 61, and a tape element 648 disposed along the tape support member 647. ing.
The tape support member 647 is formed of a vertically extending elongated member whose upper end is fixed to the outdoor side of the gear unit 62 and whose lower end is fixed to the outdoor side surface of the plate member 64a. A biasing means 647a is disposed to pull the lower end of 648 downward.
The tape element 648 includes a rain detection tape 648a whose upper end is fixed to the upper end of the tape support member 647, and a tape output portion 648b connected to the lower end of the rain detection tape 648a. The tape output portion 648 b is configured to face the power receiving portion 632 of the interlocking bar 63 from the upper surface by being pulled downward by the biasing means 647 a.
Then, the rain detection tape 648a is wet due to rain, the humidity exceeds 90%, etc., and the rain detection tape 648a is expanded by detecting a predetermined amount of water, based on the biasing force of the biasing means 647a. Allowing the pressing force (biasing force) of the tape output portion 648 b to be transmitted to the power receiving portion 632 generates a driving force, and lowers the power receiving portion 632 and the interlocking bar 63 by about 10 mm.

(Drive of power generation means)
The drive of the power generation means will be described with reference to FIGS. 7 to 8.
With the open / close arm 4 allowing the opening / closing of the shoji 2 in the entire opening / closing range, the outdoor temperature is 18 ° C., and when there is no rainfall, the outdoor condition has no problem in ventilating the indoor environment As a result, as shown in FIG. 7A, the power generation means 64 does not operate.
7A, the upper surface of the power receiving portion 632 of the interlocking bar 63 biased upward, the lower surface of the upper output portion 642 of the thermo element unit 641, and the tape of the tape element 648 of the tape unit 646. In the state of being in contact with the lower surface of the output portion 648b, the regulation arm 5 is stabilized without being driven.

FIG. 7 (b) shows a state in which the outdoor temperature has dropped to 10 ° C. from the state shown in FIG. 7 (a).
When the temperature drops, the wax in the thermoelement 643 is contracted, and the blocking shaft 643a is lowered about 10 mm downward by the downward pressing force of the upper output portion 642. The upper output portion 642 is in contact with the power receiving portion 632 of the interlocking bar 63 from the upper side, but the urging force of the urging means for urging the interlocking bar 63 upward is lower than that of the upper output portion 642 Since the lower side is set larger, the lower surface of the upper output portion 642 can push the power receiving portion 632 downward to drive the interlocking bar 63 downward. As the interlocking bar 63 is driven downward, the restricting arm 5 is driven to the restricting position.
At this time, since the tape output portion 648b of the tape unit 646 is only in contact with the power receiving portion 632 from above, the downward driving of the interlocking bar 63 is not hindered.

From the state shown in FIG. 7 (a), a state in which there was rainfall is shown in FIG. 8 (a).
When the rain detection tape 648a gets wet due to rain, or when the humidity exceeds 90%, for example, the rain detection tape 648a expands and the tape output portion 648b descends downward about 10 mm by the urging force of the urging means 647a. When the tape output portion 648b is lowered, the tape output portion 648b pushes the power receiving portion 632 downward against the biasing force of the biasing means which biases the interlocking bar 63 upward, and the interlocking bar 63 is downwardly moved. To drive. As the interlocking bar 63 is driven downward, the restricting arm 5 is driven to the restricting position.
At this time, the upper output portion 642 of the thermo element unit 641 is prevented from transmitting the pressing force downward by the blocking shaft 643 a and only contacts the power receiving portion 632 from the upper side. It does not disturb the downward drive.

The outdoor temperature drops to 10 ° C. from the state shown in FIG. 7 (a), and a state where there is rainfall is shown in FIG. 8 (b).
When the temperature drops, the wax in the thermoelement 643 is contracted and the blocking shaft 643a is lowered about 10 mm downward by the pressing force of the upper output portion 642. In addition, when the rain detection tape 648a gets wet due to rain, the rain detection tape 648a expands and the tape output portion 648b descends downward by about 10 mm by the biasing force of the biasing means 647a.
Therefore, the power receiving portion 632 of the interlocking bar 63 is pushed downward by the upper output portion 642 and the tape output portion 648b, and the interlocking bar 63 is driven downward, whereby the restricting arm 5 is driven to the restricting position. Ru.
And in either case of FIG. 7 (b) and FIG. 8, the maximum opening-and-closing angle of shoji 2 will be regulated by regulation arm 5.

As described above, the natural ventilation window of the present embodiment maintains the closing state of the shoji by operating the opening and closing arm manually or electrically, or in the opening and closing range of the shoji from the closing state to the full opening state. Since the open / close angle can be automatically controlled by the control arm according to the outdoor conditions without using a power such as electric motor while maintaining the state of natural ventilation, the wind by rain or low temperature etc. It is possible to maintain natural ventilation in the range of a small opening / closing angle which does not allow rain to fall while preventing shoji from being greatly opened and falling.
The drive means for driving the restriction arm may be provided with any drive means of the drive means for generating the drive force by the presence or absence of rainfall, the change of the air temperature, and the change of the humidity, or they may be provided in combination. When provided in combination, the regulation arm can be driven to regulate the maximum opening / closing angle if any one of the conditions is satisfied.
In addition, the drive control of the regulation arm does not use the power such as electric power, and utilizes the power generated by the property change of the substance such as the volume and length changing according to the temperature and humidity. And the drive control of the control arm are independent, so that regardless of the state of the open / close arm manually or electrically operated by the user, the control arm can be driven to control the open / close angle, natural ventilation Rain blowing can be prevented while maintaining the condition.

In the present embodiment, the thermo element and the rain sensing tape are used as an example of the control member driving means that generates power according to temperature and humidity, but using property changes due to changes in temperature and humidity. Any power source can be used as long as it generates power, and it is also possible to use them in combination.
Moreover, although the natural ventilation window of this embodiment is a natural ventilation window which rotates and opens and closes centering on a spindle with respect to a window frame, if it is a natural ventilation window which Shoji opens and closes naturally by external force, such as wind, etc. There is no particular limitation on the method of opening and closing the sliding window and the like.
