The bathroom air is exhausted to the outside by a ventilation fan and ventilated, and as a fitting to be installed at the entrance of such a bathroom, the ventilation fan is used by using the fitting with the conventional ventilation valve described above. It is possible to prevent negative pressure in the bathroom when it is driven to ventilate the bathroom.
For example, when the ventilation fan is driven and the inside of the bathroom becomes negative pressure, the ventilation valve swings upward to open the ventilation path, the air in the dressing room flows into the bathroom, and the ventilation fan stops when the ventilation fan stops. It swings in a downward posture that closes the ventilation path and prevents steam inside the bathroom from leaking to the dressing room side.

The ventilating valve of the joinery described above swings upward and opens the ventilation path when the air pressure on the bathroom side of the ventilation path is lower than the air pressure in the dressing room of the ventilation path. Is larger if the swing angle of the ventilation valve to the upward posture is large, and smaller if the swing angle is small.
The swing angle of the ventilation valve to the upward posture is larger as the air pressure in the bathroom is lower, and the air pressure in the bathroom is lower as the exhaust amount (air flow rate) of the ventilation fan is larger.
From this, the open area of the ventilation path is determined by the exhaust amount of the ventilation fan, and if the exhaust amount of the ventilation fan is large, the open area is large, and if it is small, the open area is small.

  In recent years, it has been practiced to ventilate the building 24 hours using a ventilation fan in the bathroom, but because the discharge amount of the ventilation fan during the 24-hour ventilation is set to be less than the discharge amount during normal bathroom ventilation The open area of the ventilation path is smaller than the open area at the time of normal bathroom ventilation, and the required air circulation amount, that is, the ventilation amount cannot be obtained.

  An object of the present invention is to provide a fitting and a ventilation valve operation component that can swing and hold a ventilation valve in an upward posture at a predetermined swing angle so that an open area of a ventilation path can be set to a predetermined size. .

The present invention is a fitting provided with a ventilation valve that opens and closes this ventilation path while forming a ventilation path that communicates one side in the out-of-plane direction and the other side in the out-of-plane direction on the cross member,
The ventilation valve swings in a downward posture that closes the ventilation path by its own weight, and opens upward in the differential pressure between the air pressure on one side in the out-of-plane direction and the air pressure on the other side in the out-of-plane direction. Oscillate to
The fitting is characterized in that a ventilation valve operating component that swings and holds the ventilation valve in an upward posture at a predetermined swing angle is attached to the cross member.

In the fitting according to the present invention, the ventilation valve operating component can be configured to manually swing and hold the ventilation valve in the downward posture in the upward posture.
In this way, the ventilation valve operating component can be easily attached to the cross member, and the number of constituent members can be reduced and the cost can be reduced.

In the fitting of the present invention, the ventilation path communicates the one side opening on one side in the out-of-plane direction of the cross member, the other side opening on the other side in the out-of-plane direction, and the one side opening and the other side opening. Having a communication path,
The ventilation valve operating component includes a main body attached to one side surface in the out-of-plane direction of the cross member, and a ventilation valve swinging member attached to the main body so as to be rotatable in the vertical direction.
The ventilation valve swinging member is rotatable over a ventilation valve opening position that pushes the ventilation valve to an upward posture at a predetermined swing angle, and a ventilation valve closing position in which the ventilation valve is in a downward posture with its own weight, and A holding means that is held at each position can be provided.
In this way, by manually operating the lateral member from one side in the out-of-plane direction, the ventilation valve can be swung and held in an upward posture at a predetermined swinging angle, which is easy to perform.

In the fitting of the present invention, the ventilating valve swinging member is rotatable between the ventilating valve open position and the ventilating valve closed position, and the ventilating valve swinging part held at each position by the holding means, It has an operation part that turns the ventilation valve swinging part up and down,
The operation unit is in a vertical posture when the ventilation valve swinging portion is in the ventilation valve open position, and in a horizontal posture when in the ventilation valve closed position,
The holding means can turn the ventilation valve swinging portion to a position exceeding the ventilation valve closing position when the operation portion is operated from the vertical posture to the horizontal posture.
If it does in this way, a ventilation valve can be made into the upward posture and the downward posture of a predetermined rocking angle by moving an operation part up and down.
In addition, when the operation unit is operated from a vertical posture to a horizontal posture at a high speed, the ventilation valve swinging unit can be rotated to a position exceeding the ventilation valve opening position. The force does not break when loaded.

The joinery of the present invention can be attached with a screw that is screwed onto a reinforcing plate that is attached by adhering the main body of the ventilation valve operating component to one side surface in the out-of-plane direction of the cross member.
In this way, the ventilation valve operating component can be firmly attached regardless of the thickness of the side wall in the out-of-plane direction which is one side surface in the out-of-plane direction of the cross member.

According to the fitting of the present invention, since the ventilation valve can be swung and held in the upward posture by the ventilation valve operating component, the open area of the ventilation path can be set differently from one side in the out-of-plane direction. Regardless of the differential pressure of the side air pressure, it can be a predetermined magnitude.
Thereby, when using the ventilation fan of a bathroom as ventilation for 24 hours, the required ventilation amount is obtained.
Further, if the holding of the ventilation valve by the ventilation valve operating component is released, a normal ventilation operation can be performed.

As shown in FIG. 1, the joinery 1 has an opening / closing body 3 attached to a frame 2 so as to be freely opened and closed.
The frame 2 has an upper horizontal frame member 20, a lower horizontal frame member 21, and left and right vertical frame members 22 connected in a square shape.
The openable / closable body 3 is a shoji that connects an upper rod 30, a lower rod 31, and left and right vertical rods 32 in a rectangular shape, and a panel 33 is mounted therein.
The left and right vertical rods 32 of the opening / closing body 3 are supported by the frame body 2 so as to be rotatable in the opening / closing direction, thereby forming a hinged door.

The joinery 1 is not limited to a swing door, and may be a sliding door, a single sliding door, a sliding door, a folding door, or the like. The opening / closing body 3 may be a door or the like.
The joinery of this embodiment is a joinery for a bathroom, but is not limited to this, and may be a joiner for an indoor entrance, a joiner for an entrance that separates the room from the outdoor, a joinery for a window, or the like.

As shown in FIG. 2, the upper horizontal frame member 20 has a ventilation path 4.
The ventilation path 4 includes a one-side opening 40 on one side in the out-of-plane direction, another opening 41 on the other side in the out-of-plane direction, and a communication passage 42 that communicates the one-side opening 40 and the other-side opening 41. Have.
The one side opening 40 opens to the dressing room side (one side in the out-of-plane direction) with the opening / closing body 2 as a boundary, and the other side opening 41 opens to the bathroom side (the other in the out-of-plane direction etc.) with the opening / closing body 2 as a boundary. It opens to the side), and air, water, etc. flow through the ventilation path 4 to the bathroom side and the dressing room side.

The ventilation path 4 is opened and closed by a ventilation valve 5.
The upper part of the ventilation valve 5 is attached to the upper horizontal frame member 20 so as to be swingable in the out-of-plane direction.
The ventilation valve 5 swings over a downward posture that closes the ventilation path 4 and an upward posture that opens the ventilation path 4. For example, the ventilation valve 5 is mounted near the one side opening 40 of the communication passage 42, and swings in the vertical direction over a downward posture that closes the one side opening 40 and an upward posture that opens.
The ventilation valve 5 swings downward with its own weight and closes the ventilation path 4.
When the air pressure in the other side opening 41 of the ventilation path 4 becomes lower than the air pressure in the one side opening 40, the air pressure swings upward due to the differential pressure of the air pressure, and the ventilation path 4 is opened. To do.

A ventilation valve operating component 6 capable of manually swinging and holding the ventilation valve 5 in the downward posture in the upward posture or releasing the holding is attached to the upper horizontal frame member 20, and the other side opening 41 of the ventilation path 4 is attached. Regardless of the differential pressure between the air pressure and the air pressure of the one side opening 40, the ventilation valve 5 is manually swung and held in an upward posture at a predetermined swing angle, and the open area of the ventilation path 4 is increased to a predetermined size. It can be done.
As shown in FIG. 1, one ventilation valve operation component 6 is attached to the longitudinal center of the upper horizontal frame member 20, but it may be attached to both sides of the longitudinal direction, or three or more ventilation valve operation components. 6 may be attached.

  Therefore, when the inside of a building is ventilated for 24 hours using a ventilation fan in the bathroom, the ventilation valve 5 is manually operated to swing the ventilation valve 5 in an upward posture at a predetermined swing angle. Since the opening area of the ventilation path 4 can be set to a predetermined size, the exhaust amount of the ventilation fan at the time of 24-hour ventilation can be obtained at least as much as the ventilation amount required at the time of normal bathroom ventilation.

During normal bathroom ventilation, if the ventilation valve operating component 6 is manually operated to release the swing of the ventilation valve 5, the ventilation valve 5 swings downward and closes the ventilation path 4.
And since the air pressure of the other side opening part 41 becomes lower than the air pressure of the one side opening part 40, the ventilation valve 5 rocks in an upward attitude | position, and the air by the side of a dressing room flows into the bathroom side.
If the air pressure in the other side opening portion 41 becomes equal to the air pressure in the one side opening portion 40, the ventilation valve 5 swings downward with its own weight.
Thus, a normal bathroom ventilation operation can be performed.

Next, details of each part will be described.
As shown in FIG. 3, the ventilation valve 5 includes a plate-like valve main body 50 that is thin and has a mounting portion 51 provided on the upper portion of the valve main body 50.
The mounting portion 51 is substantially semicircular in cross section, and the mounting portion 51 is rotatably mounted in an out-of-plane direction in a recess 20a having a substantially semicircular cross section in the upper horizontal frame member 20.
When a flocking (mohair) 52 is provided near the lower part of one side surface 50a in the out-of-plane direction of the valve body 50, and the ventilation valve 5 swings downward, the flocking 52 is located on the one side opening 40 as shown in FIG. The sound is suppressed by touching the lower opening edge.

The ventilation valve operating component 6 is attached to the main body 6a, the main body 6a so as to be rotatable in the vertical direction, and the ventilation valve swinging part 6b held at the ventilation valve open position and the ventilation valve closed position, and the ventilation valve. A ventilation valve swinging member having an operation part 6c for rotating the swinging part 6b up and down is provided.
The main body 6a is attached below the one side opening 40 on the one side surface 20b in the out-of-plane direction of the upper horizontal frame member 20, the ventilation valve swinging part 6b faces the one side opening 40, and the operation part 6c is It projects to one side in the out-of-plane direction of the horizontal frame member 20.

When the ventilation valve swinging portion 6b is in the ventilation valve open position, as shown in FIG. 3, the ventilation valve 5 protrudes into the communication passage 42 from the one side opening 40 and comes into contact with the ventilation valve 5. Push up to the upward angle of the moving angle.
When the ventilation valve swinging portion 6b is in the ventilation valve closed position, the ventilation valve 5 comes out of the communication passage 42 as shown in FIG. 4 and is separated from the ventilation valve 5, and the ventilation valve 5 swings in a downward posture by its own weight.

The operation portion 6c protrudes to one side in the outer surface direction from one side surface 20b in the outer surface direction of the upper horizontal frame member 20.
As shown in FIG. 3, when the ventilation valve swinging portion 6 b is in the ventilation valve open position, the operation portion 6 c is in a vertically oriented position below the one side opening 40, so that the operation portion 6 c is in the one side opening 40. The air smoothly flows through the one-side opening 40 without obstructing the flow of air flowing through the one side opening 40.
In addition, when the operation part 6c has one side surface 6c-1 in the out-of-plane direction facing one side in the out-of-plane direction, and when the joinery is viewed from one side in the out-of-plane direction, the one side surface 6c-1 in the out-of-plane direction. Is displayed on the surface, indicating that the operation valve 5 is in the upward posture and the ventilation path 4 is open, for example, by displaying an open character, it is detected that the ventilation path 4 is open. it can.

  As shown in FIG. 4, when the ventilation valve swinging portion 6b is in the ventilation valve closed position, the operation portion 6c is in a lateral posture and is separated from the main body 6a. Since the other side surface 6c-2 in the out-of-plane direction of the portion 6c is visually observed, it is displayed on the surface that the operation valve 5 is in the downward posture and the ventilation path 4 is closed, for example, by displaying a closed character, It can be sensed that the road 4 is closed.

Thus, since it can be visually detected whether the ventilation path 4 is open or closed, it is possible to prevent the ventilation valve 5 from being operated in an incorrect posture by the ventilation valve operation component 6.
For example, it is possible to prevent the ventilation valve 5 from being held in an upward posture during normal bathroom ventilation or to be in a downward posture during 24-hour ventilation.

Details of the ventilation valve operating component 6 will be described with reference to FIGS. 5, 6, and 7.

The support portion 61 has a protruding piece 68 that protrudes from the back surface of the mounting portion 60.

The ventilation valve swinging part 6b of the ventilation valve operating component 6 includes a main body part 70 that is mounted between the left and right support parts 61 so as to be rotatable up and down, and a swinging projecting piece 71 provided integrally with the main body part 70. Yes.
The main body 70 has a substantially U-shaped shape with a bowl-shaped plate 72 and left and right vertical pieces 73 provided integrally with the left and right ends of the plate 72. 74 project from the left and right sides and are integrally provided.
The shaft 74 is rotatably fitted in the shaft support hole 66 from the notch 67 of the left and right support portions 61.
Arc guide grooves 75 are formed on the outer surfaces of the left and right vertical pieces 73, and positioning protrusions 69 provided on the left and right support portions 61 are fitted in the guide grooves 75 so that the ventilation valve swings. A first hole 76 and a second hole 77 are formed to position and hold the moving part 6b at the ventilation valve open position and the ventilation valve closed position, and serve as holding means for holding the ventilation valve swinging part 2b at each position. In addition, you may provide a holding means in the operation part 6c.

The guide groove 75 has an arc shape centering on the center of the shaft 74, a first hole 76 is formed at one end thereof, and a second hole 77 is formed at a position slightly away from the other end.
The swinging projecting piece 71 is integrally continuous with the plate 72 of the main body 70 and protrudes from the arcuate end surface 73a of the vertical piece 73 so that the swinging projecting piece 71 contacts the valve body 50 of the ventilation valve 5. It is.

Alternatively, the positioning protrusion 69 is integrally provided on the support portion 61, or a pin or a ball to be the positioning protrusion 69 is fixedly provided, and the left and right support portions 61 are elastically deformed so that the pin or ball is inserted into the guide groove 75. You may make it fit.

Then, as shown in FIG. 8, a reinforcing plate 80 called a liner having a thicker thickness than the out-of-plane direction side wall 20c forming the out-of-plane direction side surface 20b of the upper horizontal frame member 20 is shown in FIGS. Thus, it attaches by adhering and fixing to the out-of-plane direction one side surface 20b of the upper horizontal frame material 20 with the adhesive materials 81, such as a double-sided adhesive tape.
The reinforcing plate 80 is formed with a pilot hole 82 for drilling a screw hole, and an upper end surface 20d on one side surface 20b in the out-of-plane direction of the upper horizontal frame member 20, that is, a lower opening edge of the one side opening 40. Install flush.
Therefore, an upward arrow 83 is provided on the reinforcing plate 80 so that the mounting direction of the reinforcing plate 80 can be detected by the arrow 83 so that the mounting direction of the reinforcing plate 80 can be sensed. .

As shown in FIG. 5 and FIG. 6 with the reinforcing plate 80 attached, the screw hole 84 is drilled across the reinforcing plate 80 and the one side wall 20c in the out-of-plane direction.
The attachment portion 60 of the main body 6a is brought into contact with one side surface 20b in the out-of-plane direction of the upper horizontal frame member 20 so that the reinforcing plate 80 fits into the concave portion 62, and the protruding piece 68 of the support portion 61 is arranged in the out-of-plane direction. Positioning is made in the vertical direction in contact with the upper end surface 20d of the side surface 20b.
The ventilation valve operating component 6 is attached to the one side surface 20b in the out-of-plane direction of the upper horizontal frame member 20 by screwing the screw 85 from the attachment hole 64 of the attachment portion 60 into the screw hole 83 and fixing the attachment portion 60.

  Thus, by attaching the screw 85 to the thick reinforcing plate 80 by screwing, the ventilation valve operating component 6 is firmly attached even if the wall thickness of the out-of-plane one side wall 20c of the upper horizontal frame member 20 is thin. it can.

As shown in FIGS. 3 and 5, the ventilating valve swinging portion 6b (swinging protrusion 71) swings and holds the ventilating valve 5 in an upward posture at a predetermined swinging angle at the ventilating valve open position. In the state, the positioning projection 69 is fitted into the first hole 76 and positioned and held.
Moreover, the portion of the main body 70 of the ventilation valve swinging portion 6b that is parallel to the plate 72 of the vertical piece 73 enters the recessed portion 65 and contacts the surface 64b of the vertical piece 64, so that the ventilation valve swinging portion 6b is more than that. Since the upper part is prevented from turning upward, the ventilation valve swinging part 6b does not turn upward any further even if the operation part 6c is operated with a strong force, and the ventilation valve 5 is swung to a predetermined degree. The moving angle can be held in an upward posture.

The lever 78 which is the operation portion 6c is in a vertically oriented posture and covers the mounting hole 63 and the screw 85 of the main body 6a so that they cannot be seen.
Since one side of the lever 78 in the out-of-plane direction is visually observed, it is displayed on the surface that the ventilation valve 5 is in an open state, for example, an open character is displayed.

As shown in FIGS. 4 and 6, when the ventilation valve swinging portion 6b (swinging protrusion 71) is in the ventilation valve closed position and the ventilation valve 5 is swinging downward, the positioning protrusion 69 is The second hole 77 is fitted and positioned and held.
Moreover, the second hole 77 is formed at a position away from the other end 75 a of the guide groove 75, and when the lever 78 is operated further upward, the second hole 77 is separated from the positioning protrusion 69, and the guide groove 75. The other end portion 75 a of the contact portion contacts the positioning protrusion 69.

As a result, when the lever 78 is operated upward at a high speed, the ventilation valve swinging portion 6b moves beyond the second hole 77 without stopping at the predetermined ventilation valve closed position, that is, overruns. Therefore, the lever 78 is not broken.
That is, if the overrun is not possible, a strong force is applied to the lever 78 and the lever 78 is broken. However, if the overrun is performed as described above, the lever 78 is not applied with a strong force and is not broken.

When the ventilating valve swinging portion 6b overruns, the swinging projecting piece 71 is in contact with the back surface 64a of the vertical piece 64 and is restricted so as not to overrun further.
This prevents the lever 78 from interfering with the upper portion of the upper horizontal frame member 20 or the mounting surface (ceiling, etc.) of the upper horizontal frame member 20, and the hand of the person operating the lever 78 with his / her hand is the upper horizontal frame member. The upper part of the material 20 or the mounting surface of the upper horizontal frame member 20 is prevented from being damaged.

  Thus, if the lever 78 is operated upward, the ventilation valve swinging part 6b is in the ventilation valve closed position, and if the lever 78 is operated downward, the ventilation valve swinging part 6b is in the ventilation valve open position. 5 can be easily rocked and held manually over an upward posture and a downward posture.

Since the ventilation valve 5 swings between an upward posture that opens the one side opening 40 and a downward posture that closes the ventilation valve 5, the ventilation valve 5 is closer to one side in the out-of-plane direction of the communication path 42, and The distance in the out-of-plane direction with the ventilation valve swinging portion 6b is short.
Accordingly, the ventilation valve swinging part 6b of the ventilation valve operating component 6 can reliably rotate the ventilation valve 6 to a predetermined angle upward, and the ventilation valve swinging part 6b can be made compact.

In the above-described embodiment, the ventilation path 4 is formed in the upper horizontal frame member 20 and the ventilation valve operating component 6 is attached. However, the ventilation is performed on the lower horizontal frame member 21 or the upper rod 30, the lower rod 31, and the intermediate rib. A passage 4 may be formed and a ventilation valve operating component 6 may be attached.
That is, the ventilation path 4 may be formed in the crosspiece of the joinery, and the ventilation valve operation component 6 may be attached.

In the above-described embodiment, the operating portion 6C of the ventilation valve operating component 6 is the manually operated lever 78. However, the ventilation valve swinging portion 6b can be automatically rotated as a power source such as a motor. good.
For example, the motor is driven by a signal for normal ventilation operation of a bathroom ventilation fan, the ventilation valve swinging part 6b is set to the ventilation valve closed position, and the motor is driven by a signal for 24 hours ventilation operation of the bathroom ventilation fan to swing the ventilation valve. Let the part 6b be a ventilation valve open position.
