Description

  The present invention relates to a window for performing natural ventilation such as wind ventilation and gravity ventilation while automatically adjusting the opening degree by wind pressure.

  In recent years, frequent ventilation has been recommended for measures such as sick house. Ventilation methods are broadly divided into natural ventilation and mechanical ventilation. The former natural ventilation is classified into wind ventilation and gravity ventilation. Wind ventilation opens two windows on different sides of the room and uses the positive pressure on the windward side and the negative pressure on the leeward side to ventilate, and the gravity ventilation is warmed. Ventilation is achieved using the principle that air rises lightly.

  As the window for performing natural ventilation, for example, a window described in Patent Document 1 and a window described in Patent Document 2 have been proposed. Specifically, in Patent Document 1, the window frame, a flat-plate type shoji part rotatably attached to the window frame via a horizontal rotation shaft, and at least one of an upper part or a lower part of the shoji part are installed. A position having a weight, and the horizontal rotation axis is centered on the rotation axis, and the rotational moment related to one center of gravity of the shoji part including the weight is balanced with the rotational moment related to the other center of gravity of the shoji part A door part opening means for opening the door part at a predetermined angle with respect to the window frame in a window located on the leeward side of the building due to the action of the weight. As a window located on the windward side of an object, a window including a shoji part closing means for closing the shoji part by wind pressure received on an outer surface has been proposed.

Moreover, in patent document 2, the natural wind ventilation window which has the window frame attached facing the exterior of a room or a building, the state which put in the window frame and closed the window, and the shoji which protrudes outward from the window frame, and opens A short length provided between the rigid frame on both sides of the window frame and the shoji screen, one end pivotally attached to the top of the saddle and the other end pivotally attached to the rigid frame at a position lower than the one end. In the state where the shoji is closed, each arm has a main arm and a sub-arm having one end pivotally attached to the middle part of the heel and the other end pivotally attached to the lower part of the heel frame and longer than the main arm. Each arm is oriented almost vertically, and the pivot position of each arm to the collar is located above the pivot position of each arm to the collar, and the pivot position of each arm to the collar is It is located on the indoor side of the center of gravity and opens gently by the weight of the shoji when there is no wind. Natural wind ventilation window to 閉窓 by the wind blowing from the part side toward the sliding door has been proposed.
Japanese Patent Laid-Open No. 10-18457 Japanese Patent No. 3777441

  However, in the case of the natural ventilation window described in Patent Document 1, the wind pressure that hits the upper side of the horizontal rotation axis and the wind pressure that hits the lower side cause rotation in opposite directions, and the difference in area causes the wind pressure to rotate the shoji. Effective area. Therefore, the weight becomes heavy and the whole inertia gravity increases. As a result, there are problems such as slow opening / closing operation in a light breeze and impact noise generated by contacting the stopper with a large force. Moreover, the upper side of the shoji protrudes to the indoor side, and there is a problem that the screen door cannot be provided and the appearance is impaired.

  On the other hand, in the case of the natural wind ventilation window described in the above-mentioned Patent Document 2, the window structure has a shoji that is opened outwardly from a window frame attached facing the outside of the room or building. It has an advantage that the appearance is excellent in that it does not protrude, and that the opening / closing operation of the shoji is performed sensitively in a light wind (low wind pressure). However, in the window structure that is balanced by the weight and weight of the shoji, there is a problem that adjustment for setting the shoji to a predetermined opening degree is very complicated, and a continuous window that connects the shoji in the lateral direction and If this happens, there will be a slight difference in the degree of opening of the shoji due to factors such as backlash, friction, manufacturing error, and construction error for each shoji. .

  Therefore, the main problem of the present invention is to open and close the shoji even under a light wind under a window structure having a shoji that opens from the window frame attached facing the outside of the room or building. In addition, the opening degree of the shoji can be easily adjusted, and the shoji arranged continuously can be neatly arranged even when a continuous window is used.

In order to solve the above-mentioned problem, the present invention according to claim 1 is a natural structure comprising a window frame attached to an outer wall of a room or a building, and a shoji that is housed in the window frame and the lower side of the lower arm is turned outward and opened. In the ventilation window,

An upper arm having a relatively short length, and a lower arm having a relatively long length having one end pivotally attached to the middle portion of the vertical shaft and the other end pivotally attached to the vertical frame at a position lower than the one end. Have
In the closed state of the shoji, at least the upper arm is pivotally positioned on the outboard side with respect to the vertical frame side pivot position, and the vertical frame side pivot position is on the indoor side of the center of gravity of the shoji. Located in
A pulley is provided at a vertical frame position on the upper side of the vertical arm side pivoting position of the lower arm, one end is locked to the vertical arm pivot position of the lower arm, and the pulley is wound. One end of a spring member is connected to the other end of the cable member, and the other end of the spring member is connected to a vertical position adjustment mechanism that can adjust the vertical position.
The shoji screen has a stationary state in a balanced state in which force is balanced when the window is opened, and the opening degree is automatically adjusted from the stationary state by the wind pressure from the outside or the inside. A ventilation window is provided.

  In the first aspect of the invention, in particular, in the closed state of the shoji, the upper arm is located on the outdoor side of the vertical frame side pivoted position with respect to the vertical frame side, and the vertical frame side A pivoting position is located on the indoor side of the center of gravity of the shoji, and a pulley is provided at a vertical frame position on the upper side of the vertical arm side pivoting position of the lower arm, and one end is connected to the lower arm. Vertical position adjustment, which is locked at the pivot side pivoted position, and one end of a spring member is connected to the other end of the rope around which the pulley is wound, and the other end of the spring member can be adjusted in the vertical direction Connected to the mechanism.

  In this natural ventilation window, when the window is opened, the shoji keeps a stationary state in a balanced state with force balance, and in that stationary state, it automatically depends on the wind pressure from the outside or inside of the shoji. Adjust the opening. That is, when wind pressure (positive pressure) is applied from the outside, the shoji turns in the closing direction, and the inflow air volume is reduced by narrowing the opening of the shoji. After that, when the wind becomes no wind, the shoji will return to its original opening. Further, when the negative pressure increases or the airflow from the indoor side increases, the shoji rotates in the opening direction, and the amount of air flowing in is increased by increasing the opening of the shoji. After that, when the airflow decreases or no negative pressure is applied, the shoji returns to the original opening.

  In the present invention, by adjusting the vertical position of the other end of the spring member, it is possible to arbitrarily adjust the opening when the shoji is stationary. Further, even when the window windows are used, it is possible to arrange the shojis neatly.

  According to a second aspect of the present invention, the vertical position adjusting mechanism includes a feed screw member disposed in a vertical direction, a nut-like member screwed to the feed screw member, and a slide member that moves together with the nut-like member.

As shown in the drawing, the vertical position adjusting mechanism 12 is desirably disposed below the lower arm 5.

[Operation explanation of shoji 3]
(Closed window of shoji 3)
In the closed window state shown in FIG. 8, the shoji 3 maintains the closed state. In the upper arm 4, a moment for rotating the upper arm 4 outwardly about the vertical frame side pivot point B by the weight of the shoji w (W / 4) acting on the vertical axis side pivot point A. M ₁ (w · _{S 1)} is generated. Further, in the lower arm 5, because it is oriented vertically, or on the contrary to the upper arm, the downside pivot point (upper side) is slightly inclined to the indoor side, No moment is generated in the lower arm 5 or only a moment in the direction of turning in the room is generated. The moment M ₁ generated in the upper arm 4 acts as a force in a direction in which the lower arm 3B side of the shoji 3 is closed around the longitudinal arm pivot point C of the lower arm. 3 holds the closed state. In addition, when the shoji is closed, force is applied in the closing direction, so that airtightness and watertightness are improved.

(Opening operation of shoji 3)
As shown in FIG. 9, when the shoji 3 is started to be opened manually or by an opening operation using a window opening device or the like, the lower arm 5 is inclined outward, and accordingly, the shoji 3 is also moved outward in the lower arm 5. An opening direction moment M ₂ (w · S ₂ ) to be rotated is generated. In addition, a closing direction moment M ₄ (P · S ₄ ) that causes the shoji 3 to close in the direction of closing the shoji 3 by the wire tension P is generated at the downside pivot point C of the lower arm 5. Further, the center of gravity K shoji 3 is moved to the outdoor side than stile side pivot point C of the lower arm 5, the closing direction moment M _{3 (W} · S ₃₎ which acts in a direction to close the sliding door 3 is appear.
The increasing rate of the moment M ₂ of the lower arm 5 is larger than that of the upper arm 4 due to the long arm length, and becomes a predetermined opening (L1), and the relationship of M ₂ > M ₁ + M ₃ + M ₄ is established. Then, the force in the direction in which the shoji 3 is opened further exceeds the force in the closing direction, and the shoji 3 automatically starts to open the window.

(Balance state of shoji 3)
As shown in FIG. 10, when the shoji 3 starts to automatically open and reaches a predetermined opening (L2), the closing moments M ₁ , M ₃ and M ₄ acting in the direction to close the shoji 3 increase. and balances the opening direction moment M ₂ to act on the direction of opening the sliding door 3. That is, ΣM _1-4 = 0 and the stationary state is maintained in an equilibrium state in which the force is balanced. The opening degree (L2) of the shoji 3 can be adjusted by manually rotating the nut-like member 14 of the vertical position adjusting mechanism 12 and moving the slide member 15 together with the nut-like member 14 up and down. is there.

  After that, in this stationary state, the opening degree is automatically adjusted by the wind pressure from the outside or inside of the shoji 3. That is, when wind pressure (positive pressure) is applied from the outside, the shoji 3 rotates in the closing direction, and the amount of air flowing in is reduced by narrowing the opening of the shoji 3. After that, when the windless state is reached, the shoji 3 returns to the original opening. Further, when the negative pressure increases or the airflow from the indoor side increases, the shoji 3 rotates in the opening direction, and the amount of air flowing in is increased by increasing the opening of the shoji 3. Thereafter, when the air flow decreases or no negative pressure is applied, the shoji 3 returns to the original opening.

[Second embodiment]
Next, the natural ventilation window 1 ′ according to the second embodiment will be described in detail with reference to FIGS. 11 and 12.
In the second embodiment, the natural ventilation window 1 ′ is opened naturally by the moments M ₁ and M ₂ acting on the upper arm 4 and the lower arm 5 without the shoji 3 being kept closed. It is what you do. After opening the window, the stationary state is maintained in an equilibrium state where the force is balanced, and in that stationary state, the opening degree is automatically adjusted by the wind pressure from the outside or inside that is applied to the shoji. This is the same as the first embodiment.

Specifically, as shown in FIG. 11, in the closed state of the shoji 3, the upper arm 4 has the vertical pivot side pivot point A from the vertical frame side pivot point B as in the first embodiment. also with located only outdoor side shift amount S _1, the longitudinal frame side pivot point B is located on the indoor side of the center of gravity K shoji.

Similarly to the upper arm 4, the vertical arm side pivot point C of the lower arm 5 is located outside the vertical frame side pivot point D by the shift amount S ₂ , and the vertical frame side The pivot point D is located on the indoor side of the center of gravity K of the shoji.

With the above structure, a moment M ₁ is generated in the upper arm 4 to rotate the upper arm 4 outward due to the weight of the shoji acting on the pivot side pivot point A. Also in the lower arm 5, since the moment M ₂ for rotating the lower side arm 5 outward direction by shoji own weight w acting on the vertical frame side pivot point C occurs, shoji 3 naturally from the closed state Begin the fenestration.

Then, as shown in FIG. 12, when the shoji 3 automatically starts to open and reaches a predetermined opening (L2), the closing direction moments M ₁ , M ₃ , M ₄ acting in the direction to close the shoji 3 are closed. Increases and balances with the opening direction moment M ₂ that acts in the direction of opening the shoji 3. That is, to hold the stationary state in equilibrium with 0.00 balance of forces becomes? M _{1 to 4 = 0.}

  In this stationary state, the opening degree is automatically adjusted by the wind pressure from the outside or inside of the shoji 3. That is, when wind pressure (positive pressure) is applied from the outside, the shoji 3 rotates in the closing direction, and the amount of air flowing in is reduced by narrowing the opening of the shoji 3. After that, when the windless state is reached, the shoji 3 returns to the original opening. Further, when the negative pressure increases or the airflow from the indoor side increases, the shoji 3 rotates in the opening direction, and the amount of air flowing in is increased by increasing the opening of the shoji 3. Thereafter, when the air flow decreases or no negative pressure is applied, the shoji 3 returns to the original opening. Further, even when strong winds that cause the shoji 3 to close act, if the wind becomes no wind, the shoji 3 starts to open by itself and returns to the original opening.

[Other examples]
