In the ventilation device of Patent Document 1, it is necessary to pinch and slide the knob to open and close the ventilation path, which is difficult for a person with a disability or the like to operate.
In the ventilation device of Patent Document 2, it is necessary to push the end portion of the surface portion of the knob in order to open and close the ventilation path. If the center part of the surface of the knob is pressed, the knob cannot be moved properly. Therefore, it is difficult to operate for people with disabilities.
In view of the above circumstances, an object of the present invention is to provide a ventilation device that can be easily opened and closed even by a person with a disability.

In order to solve the above problems, the ventilator according to the present invention is:
(A) an apparatus main body having a ventilation path connecting the room and the outside;
(B) an operation plate accommodated in the apparatus main body so as to be movable between an open position and a closed position, opening the ventilation path when in the open position, and closing the ventilation path when in the closed position;
(C) a first protrusion that is linearly movable between a first protruding position protruding from the apparatus main body and a first pressing position pressed closer to the apparatus main body than the first protruding position; A push button;
(D) linearly between a second projecting position separated from the first push button and projecting from the apparatus main body, and a second push position pushed into the apparatus main body from the second projecting position; A second push button provided to be movable forward and backward,
(E) Linked to the first and second push buttons and the operation plate, and when the first push button is pushed into the first push position, the operation plate is located at the open position, and the second push button An open / close linkage mechanism that, when pushed into the second pushing position, positions the operating plate in the closed position;
(F) Linked to the first pushbutton and the second pushbutton, and when the first pushbutton is pushed in or when the second pushbutton is pushed out, the second pushbutton is positioned at the second protruding position, and the second pushbutton is pushed A button linking mechanism for positioning the first push button at the first protruding position when pushing or releasing the first push button;
It is provided with.

According to this ventilator, the ventilation path can be opened or closed by selecting and pushing one of the first and second push buttons. In short, the ventilation path can be opened by pushing the first push button, and the ventilation path can be closed by pushing the second push button. There is no need to pinch the first and second push buttons or slide them vertically and horizontally. There is no need to pull it toward you. Therefore, the ventilator can be easily opened and closed even if there is a physical obstacle.
The advance / retreat direction of the first push button and the advance / retreat direction of the second push button are preferably parallel to each other.
It is preferable that the first push button and the second push button are arranged side by side on the indoor side surface of the apparatus main body.
The forward and backward directions of the first and second push buttons are preferably directions orthogonal to the interior side surface of the apparatus main body.

The button linking mechanism includes a button linking member interposed between the first push button and the second push button, and the button linking member is displaceable between a first displacement position and a second displacement position. Yes, when the first push button is pushed, the button connecting member is displaced toward the first displacement position to cause the second push button to protrude, and when the second push button is pushed, It is preferable that the first push button protrudes when the button connecting member is displaced toward the second displacement position.
Accordingly, the second push button can be protruded when the first push button is pressed, and the first push button can be protruded when the second push button is pressed. Whether the first push button or the second push button protrudes and which is retracted can easily determine whether the ventilation path is in an open state or a closed state.

  It is preferable that the button linking member is linearly slidable in a sliding direction that intersects a direction in which the first and second push buttons are advanced and retracted. In this case, a cam mechanism may be provided between the first push button and the button linking member to mutually convert linear movement in the forward / backward direction of the first push button and linear movement in the sliding direction of the button linking member. In addition, a cam mechanism may be provided between the second push button and the button linking member to mutually convert linear movement in the forward / backward direction of the second push button and linear movement in the sliding direction of the button linking member. Accordingly, the connection structure between the first and second push buttons and the button connection member can be simplified, and the button connection mechanism can be easily designed and manufactured. Further, when the operating plate opens and closes while sliding, the sliding operation of the operating plate and the sliding operation of the button connecting member can be linked.

It is preferable that the operating plate is slidable in the sliding direction of the button connecting member, and an opening / closing direction connecting the open position and the closed position of the operating plate intersects the sliding direction. Further, it is preferable that the operating plate is rotatable around an axis parallel to the sliding direction of the button connecting member, and the ventilation path is opened and closed by rotating while sliding along the axis.
It is preferable that the opening / closing connection mechanism includes a connecting member that connects the operation plate and the button connecting member so as not to be relatively displaceable in the sliding direction and to be relatively displaceable in the opening / closing direction. Accordingly, the operating plate can be moved in the opening / closing direction while sliding integrally with the button connecting member.

It is preferable that the opening / closing linking mechanism includes a biasing member that pushes the operation plate at the closed position from the open position side. The urging member is provided with a cam surface and a pressing surface continuously in the sliding direction, and when the button linking member is displaced toward the second displacement position, the cam surface is one of the operating plates. It is preferable that the operation plate is guided toward the closed position by hitting a portion, and the pressing surface is pressed against the operation plate at the closed position.
Thus, when the first push button is pushed in and the ventilation path is closed, the operating plate can be reliably guided to the open position by the cam surface of the urging member. Further, when the operating plate reaches the open position, the operating plate can be urged in the closing direction by the urging member, and the closed state of the ventilation path can be reliably maintained.

The operating plate is formed with an escape portion that escapes from the biasing member when the operating plate is located between the close position closer to the closed position than the open position and the open position. It is preferable that one end portion in the displacement direction of the escape portion when in between the position and the closed position is in contact with the cam surface.
As a result, it is possible to avoid interference with the urging member when the operation plate opens and closes. Moreover, the said one end part of a relief part can be made into a cam follower with respect to the said cam surface.

  The button linking mechanism includes first button urging means such as a spring that urges the first push button toward the first protruding position, and a spring that urges the second push button toward the second protruding position. 2nd button urging means, such as these, may be included. Thus, the first push button can be returned to the first protruding position when the first push button is released, and the second push button can be returned to the second protruding position when the second push button is released. In this case, it is preferable that the opening / closing connection mechanism further includes an open holding portion and a closed holding portion. The open holding portion holds the operating plate in the open position when the first button urging means returns the first push button toward the first protruding position. The closed holding portion holds the operating plate in the closed position when the second button urging means returns the second push button toward the second protruding position. When the second push button is pushed in with the operation plate in the open position, the holding by the open holding portion is released, and the first push button is pushed in with the operation plate in the closed position. It is preferable that the holding by the closed holding portion is released.

  According to the present invention, even a person with a disability can easily open and close the ventilator.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
As shown in FIGS. 1 to 3, the ventilator 1 of this embodiment is installed as a part of a window sill 2 in a building such as a house, for example. As shown in FIG. 4, the ventilation device 1 includes a device main body 10, an operation plate 20, push buttons 30 and 40, an open / close connection mechanism 5, and a button connection mechanism 6. The apparatus main body 10 includes an indoor side wall 13, an outdoor side wall 14, and a partition wall 15. These walls 13, 14, 15 are made of one or a plurality of (in this case, three) aluminum molds, and extend in the same direction (left-right direction) as the longitudinal direction of the window tub 2. As shown in FIGS. 2 and 6, an indoor side vent 13 a is formed in the indoor side wall 13 facing the room 3. As shown in FIGS. 3 and 6, an outdoor vent 14 a is formed in the outdoor wall 14 facing the outdoor 4. As shown in FIG. 7, a ventilation path 11 is formed between the indoor side wall 13 and the outdoor side wall 14. The ventilation path 11 is connected to the room 3 through the indoor side ventilation port 13a, and is connected to the outdoor side 4 through the outdoor side ventilation port 14a. As shown in FIGS. 4 and 9, a partition wall 15 is disposed between the indoor side wall 13 and the outdoor side wall 14. The partition wall 15 divides the ventilation path 11 into two path portions (chambers). An opening 15a is formed in the partition wall 15.

  As shown in FIG. 7, the operation plate 20 is accommodated in the ventilation path 11. Here, the operation plate 20 is disposed in a chamber between the outdoor side wall 13 and the partition wall 15. As shown in FIG. 16, the operation plate 20 has a rectangular plate shape. The longitudinal direction of the working plate 20 is directed in the longitudinal direction (left-right direction) of the apparatus main body 10, and the short direction of the working plate 20 is directed in the up-down direction. A shaft portion 21 is provided at the upper end portion of the operation plate 20. The shaft portion 21 extends in the longitudinal direction of the operation plate 20, that is, in the left-right direction. As shown in FIG. 8, the shaft portion 21 is supported by the shaft support portion 16 of the apparatus main body 10 so as to be rotatable and slidable. As a result, the action | operation board 20 can rotate to the surroundings of the axial part 21 between an open position and a closed position, and can slide to right and left. The opening / closing direction connecting the open position and the closed position of the operating plate 20 intersects the sliding direction of the operating plate 20. As shown in FIG. 7, the operating plate 20 when in the open position is separated from the partition wall 15 and is inclined to the outdoor side to open the opening / closing port 15a. As a result, the ventilation path 11 is opened. Thereby, the indoor 3 and the outdoor 4 are connected through the ventilation path 11. Therefore, the air inside the room 3 and the air outside the room 4 can be ventilated. As shown in FIG. 8, the operating plate 20 when in the closed position is vertical to follow the partition wall 15 and closes the opening / closing port 15 a. As a result, the ventilation path 11 is closed. As a result, the ventilation is blocked.

  As shown in FIGS. 6 and 8, a seal member 25 is provided on the lower side of the surface of the working plate 20 facing the partition wall 15. When the operation plate 20 is in the closed position, the seal member 25 is in close contact with the partition wall 15, so that the space between the operation plate 20 and the partition wall 15 is hermetically sealed. As shown in FIG. 16, a relief portion 22 is provided at the lower end portion (the end portion opposite to the shaft portion 21) of the operation plate 20. The escape portion 22 has a notch shape extending in the longitudinal direction of the operation plate 20.

The first guide convex portion 64 is fitted in the first guide groove 33. The first guide convex portion 64 and the first guide groove 33 constitute the third cam mechanism 6c. Further, as shown in FIG. 10, a portion of the pair of upper and lower slide plate portions 62, 62 extending to the right side of the slide cam portion 61 sandwiches the second push button 40 from above and below. As shown in FIG. 15, the second guide convex portion 65 is fitted in the second guide groove 43. The fourth guide mechanism 65 and the second guide groove 43 constitute a fourth cam mechanism 6d.

  As shown in FIGS. 4 and 5, the button linking member 60 is slidable in the left-right direction (can be displaced in the displacement direction) between the first displacement position and the second displacement position in the button holder 50. . As shown in FIG. 9, the button linking member 60 at the first displacement position is at the right end of the slidable (displaceable) range of the button linking member 60. At this time, the right end surface of the slide plate portion 62 abuts against the inner wall surface on the right side of the cylindrical portion 52. Further, the locking projection 63 a is fitted in the first locking groove 53 on the right side of the locking grooves 53 and 54. The first holding portion 6e is configured by the first locking groove 53 and the locking projection 63a. The first holding portion 6e can hold the button connecting member 60 at the first displacement position, and can release the holding by pressing the second push button 40. Further, as shown in FIG. 15 (a), the first guide convex portion 64 is located at the end portion on the near side (inside the room, below in FIG. 15) of the first guide groove 33 of the first push button 30 in the pushed position. In addition, the second guide convex portion 65 is located at the end of the second guide groove 43 of the second push button 40 at the protruding position on the back side (outdoor, upper in FIG. 15). The action part 34 of the first push button 30 in the push-in position protrudes further back (upward in FIG. 15) than the button connecting member 60.

  As shown in FIG. 10, the button linking member 60 at the second displacement position is at the left end of the slidable (displaceable) range of the button linking member 60. At this time, the left end surface of the slide plate portion 62 abuts against the left inner wall surface of the cylindrical portion 52. Further, the locking protrusion 63 a is fitted in the second locking groove 54 on the left side of the locking grooves 53 and 54. The second holding portion 6f is configured by the second locking groove 54 and the locking projection 63a. The second holding portion 6f can hold the button connecting member 60 at the second displacement position, and can release the holding by pressing the first push button 30. Further, as shown in FIG. 15B, the first guide convex portion 64 is located at the end on the back side of the first guide groove 33 of the first push button 30 in the protruding position, and the second guide convex portion. The portion 65 is located at the end on the near side of the second guide groove 43 of the second push button 40 in the pushing position. The action part 34 of the first push button 30 in the protruding position is retracted into the button connecting member 60.

  As shown in FIG. 6, the end portion (left side in FIG. 6) of the button connecting member 60 protrudes from the cylindrical portion 52. The guide edges 15b of the partition wall 15 are fitted in the upper and lower guide grooves 62a at the end on the back side. The guide edge 15b extends straight in the left-right direction (the direction orthogonal to the plane of FIG. 6). Accordingly, the button connecting member 60 is allowed to slide in the left-right direction, and the movement of the button connecting member 60 other than the left-right slide is restricted.

  As shown in FIGS. 4 and 6, when the first push button 30 is in the pushing position, the action portion 35 directly contacts the action plate 20 and pushes the action plate 20 to the back side (outdoor). As a result, the operating plate 20 is in the open position. The action part 35 constitutes one element of the open / close connection mechanism 5. Further, the open / close linking mechanism 5 includes a leaf spring 70, a connecting means 71, and a guide member 80. As shown in FIGS. 4 and 16, the connecting means 71 includes a connecting member 73 and a screw 76. A connecting member 73 is disposed on the front side (inner side) of the operation plate 20 and a leaf spring 70 is disposed on the inner side (outer side). The connecting member 73, the operation plate 20, and the leaf spring 70 are connected together by a screw 76.

  The connecting member 73 has a bottomed rectangular tube shape, and an internal thread is formed on the inner peripheral surface thereof. A screw 76 is screwed into this female screw. As shown in FIG. 4, the connecting member 73 is housed in the housing recess 61 c of the button connecting member 60. In this accommodated state, the connecting member 73 cannot be displaced relative to the button connecting member 60 in the left-right direction, can be relatively displaced in the front-rear direction, and can swing up and down. As a result, the operating plate 20 is connected via the connecting means 71 so as not to be relatively displaceable in the left-right direction with respect to the button connecting member 60 and displaceable in the opening / closing direction connecting the open position and the closed position.

  The leaf spring 70 extends substantially along the longitudinal direction of the actuation plate 20 and is inclined so as to move away from the actuation plate 20 toward the back side (outside of the room) toward the tip. A base end portion of the leaf spring 70 is fixed to the operation plate 20 with a screw 76. As shown in FIGS. 4 and 7, when the operating plate 20 is in the open position, the tip of the leaf spring 70 elastically contacts the outdoor side wall 14. Therefore, the operating plate 20 in the open position is biased toward the closed position by the leaf spring 70. As shown in FIG. 5, the leaf spring 70 is separated from the outdoor side wall 14 when the operation plate 20 is in the closed position.

  As shown in FIGS. 7 and 17A, the guide member 80 includes a base portion 81 and a protruding portion 82. The base 81 has a plate shape extending in the left-right direction. As shown in FIG. 7, the base 81 is installed in a substantially horizontal posture in a portion below the operation plate 20 in the apparatus main body 10. A projecting portion 82 projects upward from the base 81 (before the drawing surface in FIG. 17B). A biasing member 83 is integrally provided on the front side (inner side, lower side in FIG. 17B) of the protruding portion 82. The biasing member 83 extends obliquely in a leaf spring shape from the side portion of the projecting portion 82, and the tip end portion thereof is bent in a circular arc shape. The outer peripheral surface of the portion bent in the arc shape in the urging member 83 constitutes the cam surface 84, and the portion between the outer surface of the portion extending obliquely in the shape of the leaf spring and the cam surface 84 forms the pressing surface 85. It is composed. The pressing surface 85 and the cam surface 84 are smoothly continuous in the left-right direction (the displacement direction of the button connecting member 60).

  As shown in FIG. 17B, the protrusion 82 is disposed at a position corresponding to the escape portion 22 of the operating plate 20. By forming the relief portion 22 in the operating plate 20, it is avoided that the operating plate 20 and the guide member 80 interfere with each other when the operating plate 20 is opened and closed. Specifically, when the operating plate 22 is between the open position (FIG. 7) and the close vicinity position (FIG. 17B), the operating plate 22 escapes from the biasing member 83 by the escape portion 22. Here, the close proximity position refers to a predetermined position closer to the closed position than the open position in the opening / closing movement range of the operating plate 22. When the operation plate 22 is between the close proximity position and the close position, the cam surface 84 contacts the right end portion 22e of the escape portion 22 (a part of the operation plate). The end 22 e is slid along the cam surface 84 as the operation plate 20 slides in the left-right direction. Accordingly, as shown in FIGS. 17B and 17C, when the operation plate 20 slides to the left, the cam surface 84 guides the operation plate 20 toward the closed position. As shown in FIG. 17C, when the operation plate 20 is in the closed position, the pressing surface 85 is pressed against the outdoor surface of the operation plate 20. Thus, the urging member 83 pushes the operating plate 20 at the closed position from the open position side to the indoor side (downward in FIG. 17C).

The opening / closing operation | movement of the ventilator 1 comprised as mentioned above is demonstrated.
Now, as shown in FIG.5 and FIG.8, the ventilation apparatus 1 shall be closed. At this time, the operating plate 20 hangs substantially vertically and is in the closed position. The first push button 30 is in the protruding position, and the second push button 40 is in the pushed position. As shown in FIG. 10, the button linking member 60 is in the second displacement position, and the locking protrusion 63 a is fitted in the second locking groove 54. By this fitting, the button connecting member 60 is prevented from sliding, and the operation plate 20 is held in the closed position.

  When the ventilator 1 is opened from the above closed state, the push portion 31 of the first push button 30 is pushed toward the apparatus main body 10. At this time, the peripheral side portion of the first push button 30 is guided to the inner peripheral surface of the first button accommodating hole 51a. Thus, the first push button 30 can be pushed linearly. The central portion of the pressing portion 31 may be pushed straight, and the operation is easy. As the first push button 30 is pushed, the button connecting member 60 is slid rightward by the cam action of the first sliding contact surface 32 and the first guide surface 61a. At this time, the latching claw 63 is elastically deformed, the latching protrusion 63a is disengaged from the second latching groove 54, and the button connecting member 60 is allowed to slide. At the same time, the first guide convex portion 64 is relatively obliquely guided toward the front side of the first guide groove 33 (downward in FIG. 15B). The button connecting member 60 can also slide in the right direction by the cam action between the first guide convex portion 64 and the inner peripheral surface of the first guide groove 33. Further, the second push button 40 protrudes from the pushing position by the cam action of the second guide surface 61b and the second sliding contact surface 42. At this time, the peripheral side portion of the second push button 40 is guided to the inner peripheral surface of the second button accommodating hole 51b. As a result, the second push button 40 can be projected and moved linearly. Further, the second guide convex portion 65 is relatively obliquely guided to the back side of the second guide groove 43 (upward in FIG. 15B). The second push button 40 can also protrude by a cam action between the second guide convex portion 65 and the inner peripheral surface of the second guide groove 43.

  As the button connecting member 60 slides in the right direction, the operation plate 20 is slid in the right direction together with the button connecting member 60. Eventually, the action portion 35 abuts against the operation plate 20. When the first push button 30 is further pushed from there, the operation plate 20 is rotated toward the open position while sliding in the right direction.

  As shown in FIGS. 4, 6, and 9, when the first push button 30 is pushed to the pushing position, the button linking member 60 reaches the first displacement position, and the right end surface of the button linking member 60 is the cylindrical portion 52. And the locking projection 63 a is fitted into the first locking groove 53. By the engagement of the first locking groove 53 and the locking projection 63a, the button connecting member 60 is held at the first displacement position. Further, as shown in FIG. 15A, the first guide convex portion 64 abuts against the front end portion of the first guide groove 33. Further, the second push button 40 reaches the protruding position, and the locking convex portion 44 strikes the end portion on the near side of the second guide concave portion 56. The second guide convex portion 65 is located at the back end of the second guide groove 43.

  As shown in FIGS. 6 and 7, when the first push button 30 reaches the push-in position, the operation plate 20 is brought into the open position. As a result, the ventilation path 11 is opened, and the outdoor 4 air and the indoor 3 air can be ventilated. As shown in FIGS. 4 and 7, at this time, the plate spring 70 elastically hits the outdoor side wall 14 to urge the operating plate 20 in the closing direction. On the other hand, as described above, since the locking protrusion 63a is fitted in the first locking groove 53, the button connecting member 60 is held at the first displacement position, and as a result, the first push button 30 is held at the pressing position. The Therefore, the operating plate 20 can be held in the open position also by the above urging of the leaf spring 70, and the ventilation device 1 can be maintained in the open state.

  When closing the ventilation device 1, the push portion 41 of the second push button 40 is pushed toward the device body 10. At this time, the peripheral side portion of the second push button 40 is guided to the inner peripheral surface of the second button accommodating hole 51b. Accordingly, the second push button 40 can be pushed linearly. It is only necessary to push the central portion of the pressing portion 41 straight, and the operation is easy. As the second push button 40 moves, the button linking member 60 is slid leftward by the cam action of the second sliding contact surface 42 and the second guide surface 61b. At this time, the locking claw 63 is elastically deformed, the locking projection 63a is disengaged from the first locking groove 53, and the button connecting member 60 is allowed to slide. At the same time, the second guide convex portion 65 is relatively obliquely guided toward the front side of the second guide groove 43 (downward in FIG. 15A). The button linking member 60 can also slide in the left direction by a cam action between the second guide protrusion 65 and the inner peripheral surface of the second guide groove 43. Further, the first push button 30 is moved from the push-in position to the protruding position by the cam action of the first guide surface 61a and the first sliding contact surface 32. At this time, the peripheral side portion of the first push button 30 is guided to the inner peripheral surface of the first button accommodating hole 51a. Accordingly, the first push button 30 can be linearly projected and moved. Moreover, the 1st guide convex part 64 is guided diagonally to the back | inner side (upper in FIG. 15A) of the 1st guide groove 33 relatively. The first push button 30 can also protrude by a cam action between the first guide convex portion 64 and the inner peripheral surface of the first guide groove 33.

  As the first push button 30 protrudes, the operating plate 20 is rotated in the closing direction by the urging of the leaf spring 70. Further, the operation plate 20 rotates in the closing direction by its own weight. At the same time, the operation plate 20 is slid leftward together with the button connecting member 60. As shown in FIG. 17 (b), the right end portion 22 e of the escape portion 22 hits the cam surface 84 when the operating plate 20 comes to a close proximity position near the closed position. When the operation plate 20 is further slid leftward by further pressing operation of the second push button 40, the end 22e slides along the cam surface 84 toward the pressing surface 85. Thereby, the operation plate 20 can be reliably guided toward the closed position.

  As shown in FIG. 17C, when the second push button 40 is completely pushed to the push position, the button connecting member 60 reaches the second displacement position, and the operation plate 20 reaches the closed position. At this time, the pressing surface 85 of the urging member 83 rides on the outer surface of the operation plate 20. As a result, the urging member 83 presses the operating plate 20 in the closing direction. Therefore, the operation plate 20 can be reliably maintained in the closed position, and the seal member 25 can be securely adhered to the partition wall 25. As a result, the ventilation path 11 can be reliably maintained in the closed state.

  As shown in FIGS. 5 and 10, when the button linking member 60 reaches the second displacement position, the left end surface of the button linking member 60 abuts against the inner wall surface on the left side of the cylindrical portion 52, and the locking projection 63 a It fits in the second locking groove 54. By the engagement of the second locking groove 54 and the locking projection 63a, the button connecting member 60 is held at the second displacement position. Further, as shown in FIG. 15B, the second guide convex portion 65 hits the end portion on the near side of the second guide groove 43. Further, the first push button 30 reaches the protruding position. Then, the locking projection 34 abuts against the front end of the first guide recess 55. The first guide convex portion 64 is located at the end on the back side of the first guide groove 33.

According to the ventilation device 1, the ventilation path 11 can be opened or closed by pushing one of the push buttons 30 and 40 straight. There is no need to pinch the push buttons 30 and 40 or slide them left or right or up and down. There is no need to pull it toward you. Therefore, the ventilator 1 can be easily opened and closed even if there is a physical obstacle.
Since the push buttons 30 and 40 may be pushed straight in a direction orthogonal to the room-side surface of the ventilator main body 10, the operation is easier.
By slightly releasing the two push buttons 30 and 40, it is possible to avoid pressing the two push buttons 30 and 40 simultaneously.
Further, it can be easily determined whether the ventilation device 1 is in the open state or the closed state depending on which of the first push button 30 and the second push button 40 protrudes. Then, by pushing the protruding one of the push buttons 30 and 40, the ventilator 1 can be closed when the ventilator 1 is in the open state, and can be opened when the ventilator 1 is in the closed state.
Since the guide grooves 33 and 43 are inclined, it is possible to prevent the push buttons 30 and 40 from falling out of the apparatus main body 10.

The present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.
When the button linkage mechanism 6 releases the pushing force to the first push button 30 (when the operation from closing to opening is completed), the first push button 30 is returned to the protruding position, and the pushing force to the second push button 40 is released. When this occurs (when the operation from opening to closing ends), a button urging means such as a spring for returning the second push button 40 to the protruding position may be provided. The open / close linking mechanism 5 may include an open holding portion that holds the operating plate 20 in the open position and a closed holding portion that holds the operating plate 20 in the closed position. When the first push button 30 is pushed in and the operation plate 20 is positioned at the open position, the first push button 30 is separated from the operation of returning to the protruding position, and the open holding portion brings the operation plate 20 into the open position. On the other hand, when the second push button 40 is pushed, the holding by the open holding unit may be released. In addition, when the second push button 30 is pushed in and the operation plate 20 is positioned at the closed position, the operation is separated from the operation of the second push button 30 returning to the projecting position after that, and the above-described close holding portion brings the operation plate 20 into the closed position. On the other hand, when the first push button 30 is pushed, the holding by the closed holding unit may be released.

The arrangement of the first push button 30 and the second push button 40 in the apparatus main body 1 may be reversed left and right. The push buttons 30 and 40 may be arranged away from each other in a direction intersecting the sliding direction of the button connecting member 60. A display indicating the open state may be attached to the push portion 31, and a display showing the closed state may be attached to the push portion 41.
The opening / closing linking mechanism 5 may have a cam mechanism that converts the advance / retreat operation of the push buttons 30, 40 into the opening / closing operation of the operation plate 20.
The cam mechanism 6a of the button linkage mechanism 6 may be a combination of a slope and a sliding body that can slide along the slope instead of being constituted by the slopes 61a and 32. The sliding body may be a pin or a rotating body. Furthermore, the slope may be replaced with a cam curved surface. The same applies to the cam mechanism 6b.
The displacement mode of the button linking member 60 is not limited to linear sliding, and may be rotation, swinging, or the like.
Instead of connecting the actuating plate 20 and the button connecting member 60, the biasing member 80 is slidable to the left and right, and the biasing member 80 and the button connecting member 60 are connected so as not to be relatively displaceable. Also good.
The opening / closing direction of the operating plate 20 may be parallel to the sliding direction of the button connecting member 60. The ventilation path 11 may be opened and closed simply by sliding the operation plate 20.

  The present invention is applicable as a ventilator provided on a joinery or wall of a building such as a house.
