Abstract

<P>PROBLEM TO BE SOLVED: To provide a fitting which can secure a predetermined ventilation amount and increase the ventilation amount comparatively easily. <P>SOLUTION: The fitting has a first and second block sections 242, 243 extending vertically while holding a rotary shaft 241 in between, reducing the torque for turning a block member 24, which can surely turn the block member 24 even under a small pressure difference to open the second openings 22, 23 on upper and lower sides. While under a less pressure difference, the block member 24 can turn to a blocking position through the weight difference between the first and second block sections 242, 243 to block the second openings 22, 23 on upper and lower sides. Furthermore, the areas of the first and second block sections are enlarged while adequately adjusting the weight balance between the first and the second block sections 242, 243, configuring the block member 24 having a larger area without increasing so much the rotary torque. <P>COPYRIGHT: (C)2010,JPO&amp;INPIT

Description

  The present invention relates to a joinery including a shoji that is supported by a frame so as to be freely opened and closed.

Conventionally, as a joinery, there is a bathroom entrance fitting that includes a shoji supported by a frame and that can ventilate the bathroom through a ventilation passage provided in a gap between the frame and the shoji (see, for example, Patent Document 1). .
In the joinery described in Patent Document 1, a ventilation passage is formed between the upper frame and the upper heel, and an opening / closing valve capable of opening and closing the ventilation passage is attached to the upper frame. The on-off valve is configured to open by the pressure difference generated inside and outside of the bathroom by making the bathroom side negative with a bathroom ventilation fan, etc., and closed by the biasing force of the spring or its own weight, or operation of a lever, string, etc. It is configured to be able to be opened and closed manually through a member.

JP 2008-144438 A

  By the way, in the conventional fitting as described in Patent Document 1, when the opening / closing valve is configured to open due to a pressure difference between inside and outside of the bathroom, the opening / closing valve rotates against the urging force and weight of the spring. It is necessary to have a sufficient pressure difference, and depending on the performance of the ventilation fan, a sufficient pressure difference may not be generated and the on-off valve may not be fully opened. For this reason, even if it is going to enlarge a ventilation channel in order to increase a ventilation amount, the size of an on-off valve is difficult to enlarge, and there also exists a problem that it is difficult to respond to an increase in a ventilation amount.

  An object of the present invention is to provide a fitting capable of ensuring a predetermined ventilation amount and increasing the ventilation amount relatively easily.

  The joinery of the present invention is a joinery comprising a frame having an upper frame, a lower frame, and left and right vertical frames, and a shoji that is supported by the frame so as to be freely opened and closed. The upper frame, the lower frame, the left and right vertical frames, and the upper rod in a state in which the shoji is closed with the saddle and the left and right vertical rods, and a face material supported by each of the ribs. In addition, the lower rod and the left and right vertical rods are in contact with each other via an airtight material, and the one side space partitioned by the shoji and the other side space are configured to be able to communicate with each other through the ventilation unit, and the ventilation unit Has a first opening that opens in the space on the one side, a second opening that opens in the space on the other side, and a closing member that can close and open the second opening. The two openings are composed of a pair arranged in parallel with each other, and are closed at a position separating the pair of second openings. The member is rotatably supported, and the closing member has a first closing portion and a second closing portion that are arranged side by side with the rotation center and can close the pair of second openings, respectively. The pair of second openings is configured to be openable by rotating with a difference in atmospheric pressure between the space on one side and the other side.

  According to the present invention, the second opening that opens to the space on the other side is configured as a pair, and the pair of second openings is closed by having the first closing portion and the second closing portion that can be closed respectively. The closing member is supported in a seesaw state by constituting the member and rotatably supporting the closing member at a position where the pair of second openings are partitioned. Accordingly, by appropriately setting the weight balance between the first closing portion and the second closing portion, the torque for rotating the closing member can be reduced, and the pressure difference between the space on one side and the other side is reduced. However, the closing member can be reliably rotated to open the second opening, and ventilation can be performed. Furthermore, even when the opening area of the first opening or the second opening is increased to increase the ventilation volume, the area of the first closing part and the second closing part can be increased while appropriately adjusting the weight balance. For example, the closing member can be configured without increasing the rotational torque, and the ventilation rate can be increased relatively easily.

At this time, in the joinery of the present invention, the pair of second openings are arranged side by side in the vertical direction, and the closing member is rotatably supported around a substantially horizontal rotational axis provided at a position where the second openings are vertically divided. It is preferable that the first closing part is provided on the upper side of the rotating shaft, and the second closing part is provided on the lower side of the rotating shaft.
According to such a configuration, a pair of second openings are formed side by side in the vertical direction, and the blocking member is supported so as to be rotatable about a substantially horizontal rotation axis. When forming and providing ventilation means on the upper frame, lower frame, upper collar, lower collar, etc., or when providing ventilation means across the upper frame and upper collar, or across the lower frame and lower collar, The opening width of the second opening can be increased, and the ventilation amount can be easily increased. At this time, in the closing member, if the lower second closing portion is formed to be heavier than the upper first closing portion, the pressure difference between the space on the one side and the other side disappears or becomes smaller than a predetermined pressure difference. Since the heavy second closing portion rotates downward by its own weight, the second opening can be reliably closed by rotating the closing member in the closing direction. Even in this case, if the weight difference between the first closing portion and the second closing portion does not need to be so large, and the weight difference is set so as to exceed the rotational resistance of the rotating shaft, it is blocked by the pressure difference. The member can be reliably rotated. The external force for rotating the closing member in the closing direction is not limited to that due to gravity, and the closing member may be rotated in the closing direction by an elastic force such as a spring. A driving means for closing may be provided, and the closing member may be rotated in the closing direction by the driving force.

Further, in the joinery of the present invention, the closing member rotates in a direction in which the first closing portion faces the space on the one side and the second closing portion faces the space on the other side, and the pair of second portions It is preferable that the opening is opened.
According to such a configuration, the pair of second openings is formed by the closing member rotated so that the upper first closing part faces the one side space and the lower second closing part goes to the other side space. A downward intake path is formed from the first to the other space. Therefore, if the space on the other side is a bathroom, air can be taken downward from a dressing room or the like outside the room, and after the introduced air is circulated inside the bathroom, it can be exhausted from an upper ventilation fan or the like. , Ventilation in the bathroom can be carried out efficiently.

Furthermore, in the joinery of the present invention, the ventilation means is provided in the lower arm, and the pair of second openings are formed on a side surface of the lower arm with a lower arm partition portion that partitions the interior of the lower arm up and down. The first opening and the lower second opening communicate with each other through a third opening formed in the lower and upper partitioning portions, or the ventilation means is arranged on the lower frame. Of the pair of second openings, the upper second opening is formed on a side surface of the lower collar, and the lower second opening includes the lower frame and the lower collar. It is preferable that the first opening and the lower second opening communicate with each other through a third opening formed in the bottom surface of the lower collar.
According to such a configuration, the ventilation means is provided on the lower heel, which is the lower part of the joinery, or is provided across the lower frame and the lower heel, so that the space on the other side passes from the space on one side to the lower part of the joinery. Air can be introduced. Therefore, if the space on the other side is a bathroom, air can be taken into the vicinity of the bathroom floor from the outside, such as a dressing room, and after the bathroom floor is dried with the taken-in air, it is exhausted from the upper ventilation fan, etc. By doing so, moisture in the bathroom can be efficiently removed.

In addition, when the ventilation means is provided on the lower heel, a third opening is formed in the lower heel partition portion that divides the inside of the lower heel vertically, and the first opening and the second lower side are formed through the third opening. By communicating with the opening, the first opening is positioned above the second opening on the lower side, and even if water enters the inside of the lower lid, It is possible to prevent leakage into the side space.
On the other hand, when the ventilation means is provided across the lower frame and the lower heel, a third opening is formed on the bottom surface of the lower heel, and the first opening and the lower second opening are formed through the third opening. As described above, water can be prevented from leaking into the space on one side as described above. In addition, when the ventilation means is provided across the lower frame and the lower heel, the lower second opening is formed in the gap between the lower frame and the lower heel. The gap is blocked by the second blocking portion, and entry of water or the like from the space on the other side into the gap can be prevented, and contamination inside the gap can be prevented.

Further, in the joinery of the present invention, the ventilation means is provided in the upper heel, and the pair of second openings are formed on a side surface of the upper ridge with an upper ridge partitioning portion dividing the interior of the upper ridge vertically. The first opening and the lower second opening communicate with each other through a third opening formed in the upper and lower partitions, or the ventilation means is arranged on the upper frame. Of the pair of second openings, the upper second opening is formed by a gap between the upper frame and the upper collar, and the lower second opening is the upper collar. Preferably, the first opening and the lower second opening are communicated with each other through a third opening formed on the upper surface of the upper collar.
According to such a configuration, the ventilation means is provided on the upper heel, which is the upper part of the joinery, or is provided across the upper frame and the upper heel, so that the space on the other side passes from the space on one side to the upper part of the joinery. Air can be introduced. Therefore, if the space on the other side is a bathroom, it is possible to prevent water from entering the ventilation means by lowering the second opening at the upper part where it is difficult to get water, and to lower the intake air along the shoji. Therefore, the bathroom side surface of the shoji can also be dried.

In addition, when the ventilation means is provided on the upper heel, a third opening is formed in the upper ridge partitioning portion that divides the inside of the upper ridge up and down, and the first opening and the second lower side are formed through the third opening. By communicating with the opening, the first opening is positioned higher than the second opening on the lower side, and water can be more reliably prevented from entering the upper lid.
On the other hand, when the ventilation means is provided straddling the upper frame and the upper collar, the upper second opening is formed in the gap between the upper frame and the upper collar. Since it is blocked by one closing portion, it is possible to prevent water and moisture from entering the gap from the space on the other side, and to prevent dirt inside the gap.

  According to the joinery of the present invention as described above, since the second opening is opened by reliably rotating the closing member of the ventilation means, a predetermined ventilation amount can be secured and the size of the closing member can be secured. Since the influence on the rotational torque is small even if the change is made, the ventilation rate can be increased relatively easily.

[First Embodiment]
FIG. 1 is a front view showing a door 1 which is a fitting according to the first embodiment. 2 and 3 are a longitudinal sectional view and a transverse sectional view showing the door 1, respectively. FIG. 4 is an enlarged longitudinal sectional view showing a lower part, which is a main part of the door 1.
1 to 3, a door 1 is an entrance / exit that partitions a dressing room that is a space on one side and a bathroom that is a space on the other side, and includes an upper frame 2, a lower frame 3, and left and right vertical frames 4. It is configured to include a joinery frame 5 as a frame body and a shoji 10 that is supported by the joinery frame 5 and that can be opened and closed on the bathroom side. The shoji 10 includes an upper lid 11, a lower rod 12, left and right vertical rods 13, and a resin panel 14 as a face material supported inside the four-sided braid.

  The upper saddle 11 and the lower saddle 12 and the left and right vertical saddles 13 of the shoji 10 are each made of an aluminum shape, and the resin panel 14 is made of a translucent synthetic resin plate. The upper rod 11, the lower rod 12 and the vertical rod 13 are formed to have concave grooves 11A, 12A, 13A that are opened inward in the finding direction at positions that are biased toward the respective bathrooms. The four peripheral edges of the resin panel 14 are held by 12A and 13A. The upper frame 2, the lower frame 3, and the left and right vertical frames 4 of the joinery frame 5 are provided with airtight materials 2A, 3A, 4A, respectively, and the airtight materials 2A, 3A, 4A in a state where the shoji 10 is closed. Since the upper abutment 11, the lower reed 12 and the left and right vertical reeds 13 are in contact with the side surfaces of the undressing room, the undressing room and the bathroom are partitioned airtight and watertight.

  In FIG. 4, the lower eyelid 12 includes a first lower eyelid 12B having a concave groove portion 12A, and a second lower eyelid 12C that constitutes the lower side of the shoji 10 facing the lower side of the first lower eyelid 12B. The both ends in the longitudinal direction are fixed to the left and right vertical hooks 13. The first lower arm 12 </ b> B has a top surface 121, a side surface portion 122 on the bathroom side, and an inclined surface portion 123 that obliquely connects the upper surface portion 121 and the side surface portion 122, and is formed in a hollow shape. 12C of 2nd lower heels are the side part 124 by the side of the dressing room, the partition piece part (lower heel partition part) 125 which protrudes from this side part 124 to the bathroom side, and the bathroom side below the partition piece part 125 And an inclined surface portion 126 having a downward slope, and a bottom surface portion 127 that connects the side surface portion 124 and the lower end portion of the inclined surface portion 126.

  In the lower collar 12, an upper ventilation path 12 </ b> D is formed in a gap where the first and second lower collars 12 </ b> B and 12 </ b> C are opposed to each other. A lower ventilation path 12E is formed between them. The partition piece 125 of the second lower rod 12C is formed with a plurality of communication holes (third openings) 128 that allow the upper ventilation path 12D and the lower ventilation path 12E to communicate with each other. Furthermore, a ventilation means 20 for ventilating the bathroom by communicating the dressing room and the bathroom with the shoji 10 closed is provided at a position straddling the lower heel 12 and the lower frame 3.

  The ventilation means 20 includes a first opening 21 that opens to the dressing room side, an upper second opening 22 and a lower second opening 23 that are a pair of second openings that open to the bathroom side, and upper and lower second openings. It has a closing member 24 that can close and open the two openings 22 and 23. The first opening 21 is formed between the end of the first lower heel 12B on the dressing room side and the upper end edge of the side surface 124 of the second lower heel 12C, and the upper second opening 22 is the side surface of the first lower heel 12B. The lower second opening 23 is formed between the lower end edge of the portion 122 and the leading end portion of the partition piece 125 of the second lower collar 12C, and the lower second opening 23 is the upper end of the partitioning piece portion 125 of the second lower collar 12C and the lower frame 3 Is formed between. That is, the upper second opening 22 and the lower second opening 23 are formed side by side in the vertical direction, and the upper and lower second openings 22 and 23 are partitioned by the partition piece 125. .

  The closing member 24 is rotatably supported at the bathroom-side front end of the partition piece 125 which is a position for partitioning the upper second opening 22 and the lower second opening 23, and extends substantially horizontally at the center of rotation. The rotation shaft 241, the first closing portion 242 provided above the rotation shaft 241 and capable of closing the upper second opening 22, and the lower second opening provided below the rotation shaft 241. And a second closing part 243 capable of closing 23. In the closing member 24, the second closing portion 243 is slightly heavier than the first closing portion 242, that is, has a slightly larger cross-sectional area, and the second closing portion 243 is lowered by its own weight, As shown in FIG. 2, the upper second opening 22 and the lower second opening 23 can be closed simultaneously. That is, in the closed state, the front end of the first closed portion 242 contacts the lower end edge of the side surface portion 122 of the first lower collar 12B, and the front end of the second closed portion 243 contacts the upper surface of the lower frame 3, thereby The lower second openings 22 and 23 are closed by the closing member 24. Further, in the closed state, the gap 3B between the upper surface of the lower frame 3 and the bottom surface portion 127 of the lower rod 12 is covered with the second closed portion 243, so that intrusion of water or the like into the gap 3B can be prevented.

  On the other hand, when a ventilation fan (not shown) provided on the ceiling or the like inside the bathroom is operated, the inside of the bathroom becomes negative pressure and a pressure difference is generated between the bathroom and the dressing room. When such an air pressure difference occurs, the closing member 24 has the first closing portion 242 facing the undressing room side and the second closing portion 243 facing the bathroom side around the rotation shaft 241 as shown in FIG. And is rotated to an open position where the upper and lower second openings 22 and 23 are opened. Then, air flows into the upper ventilation path 12D from the dressing room side through the first opening 21 in accordance with the pressure difference, and this air is branched into the bathroom through the upper second opening 22 while being branched in the upper ventilation path 12D. The other flows into the lower ventilation path 12E through the communication hole 128 and flows into the bathroom through the lower second opening 23. At this time, since the closing member 24 is lowered toward the bathroom side and opened with an inclination, the air flowing into the bathroom is blown down toward the bathroom floor surface so that the bathroom floor surface is dried. It has become. Moreover, if the operation of the ventilation fan is stopped, the pressure difference between the dressing room and the bathroom disappears, and as described above, the closing member 24 automatically closes to the closed position where the upper and lower second openings 22 and 23 are closed. It is configured to rotate.

  As described above, since the closing member 24 is supported in the seesaw state, the torque for rotating the closing member 24 can be reduced, and the closing member 24 can be used even if the pressure difference between the dressing room and the bathroom is small. Can be reliably rotated to open the upper and lower second openings 22 and 23 and to ventilate the bathroom. On the other hand, if the atmospheric pressure difference disappears or becomes smaller, the closing member 24 rotates to the closing position due to the weight difference between the first closing portion 242 and the second closing portion 243, and the upper and lower second openings 22, 23. By closing the block, airtightness and watertightness inside the bathroom can be secured. Further, by adjusting the weight balance between the first closing part 242 and the second closing part 243 as appropriate, the area of the first closing part 242 and the second closing part 243 are enlarged, thereby forming the closing member 24 having a large area without increasing the rotational torque. Correspondingly, the upper and lower second openings 22, 23, the first opening 21, the upper ventilation path 12D, and the lower ventilation path 12E are enlarged, so that the ventilation volume can be relatively easily increased. Can be increased.
