Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilation frame which is incorporated in a shoji in a form sandwiched between an upper frame or a lower frame and a panel as shown in FIG.

[0002]

2. Description of the Related Art A ventilation frame sandwiched between an upper frame or a lower frame of a shoji screen and a panel made of glass or the like is disclosed in Japanese Utility Model Publication No. Sho 62-171736. An outside air inlet is formed in the inner find piece, and a plate with a ventilation hole formed between the two find pieces is slidably arranged along one of the find pieces. The outside air can be introduced when it matches the outside air introduction port of the find piece, and the outside air is shut off when it comes off.

[0003] In order to cope with the difference in the width of the shoji, ie, the width of the panel, the ventilation frame is cut off in accordance with the size of the panel within a certain section in the length direction. Although sandwiched between the panels, in the conventional ventilation frame as shown in FIG. 14 described above, the outside air inlet is formed on the outdoor side finding piece exposed on the outdoor side and the indoor side finding piece exposed on the indoor side. Therefore, the cutting portion L is limited to a portion where the outside air introduction port is not formed, and the cutting cannot be performed at an arbitrary position.

[0004] Therefore, the width of the panel that can be accommodated by the ventilation frame is limited to the range from the entire length of the ventilation frame to the length obtained by cutting the entire length of the section that can be trimmed. It is necessary to prepare a plurality of types of ventilation frames having different possible section lengths, which requires labor and cost for production and complicates inventory management.

[0005] Further, since the ventilation frame is held at the upper and lower frames by the upper frame and the lower frame, if the expected width of the ventilation frame is different from the expected width of the upper frame and the lower frame, the ventilation frame is not held.
The expected width of the ventilation frame needs to be unified with the expected width of the upper and lower frames, but the expected width of the upper and lower frames depends on the thickness of the panel, for example, whether the panel is single-pane glass or multi-layer glass. Therefore, it is necessary to prepare a plurality of ventilation frames having different expected widths in order to cope with a plurality of upper frames and lower frames having different expected widths.

[0006] In addition, when the ventilation frame is used for a shoji facing the outdoors, rainwater may blow into the room when introducing outside air, and there is also a problem of insects entering, dust and infiltration. The present invention proposes a ventilation frame which can be cut at an arbitrary position in the length direction and can cope with upper and lower frames having different possible widths.

[0007]

According to a first aspect of the present invention, a first section having an outdoor-side finding piece and a second section having an indoor-side finding piece are provided.
A prospective piece having a ventilation opening in at least one of the profiles is formed, and an opening / closing plate for switching the ventilation opening between an open state and a closed state is movable in at least one of the first and second profiles. The need for forming the outside air introduction port on the outdoor side finding piece and the indoor side finding piece is eliminated, and the ventilation frame can be cut at an arbitrary position in the length direction.

In the first and second members, the lower end of the outdoor finding piece is positioned above the lower end of the indoor side finding piece, and the lower end of the outdoor finding piece and the lower end of the second shape member. , And between the upper end of the indoor side finding piece and the upper end of the first shaped member.

The space between the lower end of the outdoor-side find piece and the lower end of the second section and the space between the upper end of the indoor-side find piece and the upper end of the first section are open. They are continuous in the length direction and serve as an outside air introduction port on the outdoor side and an outside air introduction port on the indoor side, respectively. The outside air introduced into the ventilation frame from the outside outside air introduction port is taken into the room from the inside outside air introduction port through the ventilation port of the prospective piece.

[0010] Outside air is taken into the ventilation frame from the space between the lower end of the outdoor-side find piece and the lower end of the second section, and the upper end of the indoor-side find piece and the upper end of the first section are formed. By being taken into the room from the space between, since it is not necessary to form an outside air inlet in the outdoor side finding piece and the indoor side finding piece,
For example, except for the position of the knob connected to operate the movement of the open / close plate, there is no restriction on the cutting position for cutting down, and the ventilation frame can be cut at any position in the length direction.

Since the ventilation frame can be cut at any position, a single type of ventilation frame can be used for a panel having an arbitrary width, simplifying production and inventory management, and reducing the cost required for each. Is achieved.

The opening / closing plate is supported movably in the longitudinal direction along the projection piece as described in claim 2, and is rotatable about the longitudinal axis as described in claim 3. In the case of the second aspect, the opening / closing plate is provided with a ventilation port that can match the ventilation port of the prospective piece. In the case of the third aspect, when the opening and closing plate is closed, it is necessary to close all the ventilation holes of the prospective piece at the same time, so a blind plate is used as the opening and closing plate.

According to a second aspect of the present invention, the ventilation plate of the prospective piece is opened when the ventilation port thereof coincides with the ventilation port of the prospective piece. Is opened, and the outside air introduction port on the outdoor side communicates with the outside air introduction port on the indoor side.

The blowing of rainwater due to the opening of the space between the lower end of the outdoor finding piece and the lower end of the second section is performed as described in claim 4, wherein the outdoor finding piece and the indoor finding piece are blown. This is prevented by forming a drain piece on each of the opposing surfaces. The drain piece also serves to increase the out-of-plane stiffness of the outdoor find piece and the indoor find piece.

As described above, the outdoor outdoor air inlet is located at the lower end of the outdoor outdoor find piece, and the indoor outdoor air inlet is located at the upper end of the indoor find piece. Therefore, even if the ventilation frame itself of claim 1 has rainwater infiltration from the outdoor outside air introduction port, the ventilation frame itself has a small possibility of blowing up to the indoor outside air introduction port. The formation improves the rainwater blowing prevention effect.

The space between the lower end of the outdoor-side find piece and the lower end of the second section and the space between the upper end of the indoor-side find piece and the upper end of the first section are opened. Invasion of insects and intrusion of dust can be prevented by, for example, disposing a filter on a prospective piece as described in claim 5. In order to prevent only insects from entering, an insect net is used as a filter.

In order to prevent insects and dust from entering the room, the filter may be arranged at any position between the outdoor outside air inlet and the indoor outside air inlet. In the case where the filter is placed on the piece, it is possible to hold the mounted state of the filter using the prospective piece. In particular, when the filter is disposed on the upper surface side of the prospective piece, the filter can be replaced through the outside air inlet on the indoor side.

For a plurality of upper frames and lower frames having different estimated widths, an upper frame or a lower frame may be provided at the upper end of the first section or the lower section of the second section. 8. A gasket held by a lower frame, or a mounting portion to which a spacer is mounted, or by forming a mounting portion.
As described in, at the upper end of the first section, or at the lower end of the second section, is held on the upper or lower frame, from the upper end side of the first section to the upper frame side, or By forming a held portion having a reduced expected width from the lower end side to the lower frame side of the second section, a single ventilation frame can be used.

In the case of claim 6, since the ventilation frame is held on the upper frame or the lower frame via the gasket or the spacer attached to the mounting portion, gaskets or spacers having different expected widths may be mounted on the mounting portion. Alternatively, by reducing the expected width of the gasket or the spacer from the ventilation frame side to the upper frame or the lower frame side, the gasket or the spacer can be held by the upper frame or the lower frame having different estimated widths.

In the case of claim 7, the expected width of the held portion itself decreases from the side of the ventilation frame to the side of the upper frame or the lower frame, so that the difference in the expected width directly without interposing a gasket or a spacer. Can be held by the upper and lower frames.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A ventilation frame 1 according to the present invention is a combination of profiles formed by extrusion of an aluminum alloy or a synthetic resin or the like. As shown in FIGS. A first shape member 2 having a shape in which L is turned upside down and a second shape material 3 having an indoor side finding piece 3a and having L turned in a right and left direction. The outside air is introduced into the room through the ventilation port 4a of the prospective piece 4 formed in at least one of the member 2 and the second shape member 3.

The first section 2 and the second section 3 are relatively positioned such that the first section 2 is located above the second section 3 and the prospective piece 4 formed on one or both sides is on the other side. Are combined in such a manner as to abut the first section 2 at both ends in the longitudinal direction.
Holes 2b and 3b formed in each of the first and second sections 3
Are joined to the small caps 6 and 6 by screws 5 screwed into each other, and are integrated with each other.

In the drawing, the outdoor outdoor air inlet 7 is described later.
With the formation of the maze-shaped draining pieces 2c, 3c on the top, the prospective piece 4 is formed near the upper end of the second shaped material 3, but the prospective piece 4 is combined with the first shaped material 2. It does not matter which of the second shaped members 3 is formed or which position in the finding direction. FIGS. 1 to 8 and FIGS. 10 to 12 show the case where the prospective piece 4 is formed on the second section 3 and FIG. 9 shows the case where it is formed on the first section 2 and the second section 3.

Also, in the drawing, when the first section 2 and the second section 3 are combined, the distance between them is maintained, and when the opening / closing plate 9 described later closes the ventilation port 4a of the projection piece 4, The tip of the prospective piece 4 on the side of the first section 2 is set to the first position so that no gap is formed between the tip of the section 4 on the side of the first section 2 and the first section 2.
When the gap between the first section 2 and the second section 3 is closed by the opening / closing plate 9, the tip of the projection piece 4 does not necessarily protrude toward the opposite side. No need to hit.

When the first section 2 and the second section 3 are combined, the lower end of the outdoor section 2a is located above the lower section of the second section 3 and the upper end of the indoor section 3a. Part 1
It is located below the upper end of the profile 2.

The height direction is between the lower end of the outdoor-side finding piece 2a and the lower end of the second section 3, and between the upper end of the indoor-side finding piece 3a and the upper end of the first section 2. And open continuously in the length direction. The space between the lower end of the outdoor-side finding piece 2a and the lower end of the second profile 3 and the space between the upper end of the indoor-side finding piece 3a and the upper end of the first profile 2 are the outdoor-side, respectively. An outside air inlet 7 and an indoor side outside air inlet 8 are provided.

The outdoor outside air inlet 7 and the indoor outside air inlet 8
Due to the head drop, even if rainwater enters from the open outdoor outside air inlet 7, it is unlikely that the rainwater will blow into the room from the indoor outside air inlet 8. In the figure, draining pieces 2c and 3c are formed on the opposing surfaces of the outdoor side finding piece 2a and the indoor side finding piece 3a.

The drainage pieces 2c and 3c are formed so as to be inclined downward from the forming side to the opposite side. In the drawing, each drain piece of the outdoor side finding piece 2a and the indoor side finding piece 3a is taken to prevent rainwater from being blown in while taking in outside air.
The labyrinth is formed by alternately arranging 2c and 3c, and both drainage pieces 2c and 3c.

An opening / closing plate 9 for switching the ventilation port 4a of the prospective piece 4 between an open state and a closed state is movably supported on at least one of the first section 2 and the second section 3. The opening / closing plate 9 is disposed between the outdoor outside air introduction port 7 and the ventilation port 4a, or between the indoor outside air introduction port 8 and the ventilation port 4a, and the outdoor outside air introduction port 7 and the ventilation port 4a, or the indoor side. The ventilation port 4a is kept open by communicating the outside air inlet 8 and the ventilation port 4a, and the ventilation port 4a is kept closed by shutting off.

FIGS. 1 to 5 show an opening / closing plate 9 having a ventilation opening 9a which can be matched with the ventilation opening 4a of the prospective piece 4 so that the opening and closing plate 9 can be freely moved in the longitudinal direction along the prospective piece 4. An example in the case of being supported by the second section 3 is shown.

When the opening / closing plate 9 moves in the longitudinal direction, the opening / closing plate 9 enables introduction of outside air when its ventilation port 9a matches the ventilation port 4a of the prospective piece 4, and shuts off the outside air when it comes off. Therefore, the opening / closing plate 9 is overlapped with the prospective piece 4 and slidably supported by the first section 2 or the second section 3 or both so as to reliably shut off the outside air at the time of closing. .

FIGS. 1 to 5 show a case in which a filter 10 to be described later is arranged on the upper surface side of the prospective piece 4 and the opening / closing plate 9 is arranged so as to overlap the lower face of the prospective piece 4. Here, the operation plate 9b overlapping the rear surface of the indoor side finding piece 3a is integrated with the opening / closing plate 9 overlapping the prospective piece 4, and the lower end of the operation plate 9b is supported by the second shape member 3, so that the opening / closing plate 9 The movement in the expected direction and the movement in the finding direction are restricted.

The opening / closing plate 9 is formed in the indoor side finding piece 3a and passes through an opening (not shown) of the operation plate 9b.
When the knob 11 connected to the front side of 3a is operated, it slides in the length direction. The opening of the indoor side finding piece 3a has a length corresponding to the moving distance of the opening and closing plate 9, and for example, as shown in FIG. 1, the ventilation opening 4a of the prospective piece 4 and the ventilation opening 9a of the opening and closing plate 9 are fixed in the length direction. When a large number are formed at intervals, the distance between the adjacent ventilation ports 4a, 4a (9a, 9a) becomes the moving distance of the opening / closing plate 9.

In the case shown in the drawing, the filter 10 has an opening 12a so as not to hinder the introduction of outside air, and is held by an openable / closable or detachable pressing member 12. The openable and closable holding member 12 is rotatably supported on the first section 2 or the second section 3 around the axis in the length direction as shown in the drawing. When it is sufficient to prevent the insects from entering, an insect net is used for the filter 10.

In FIG. 9, the filter 10 is arranged between the prospective piece 4 of the first profile 2 and the prospective piece 4 of the second profile 3, and the filter 10 is held by the prospective pieces 4 and 4. The presser 12 is not required.

FIGS. 6 to 8 show that the opening / closing plate 9 is connected to the first section 2 and the second section.
An example is shown in which one of the profiles 3 is rotatably supported around a longitudinal axis. Here, the opening / closing plate 9 is supported by the first shaped member 2 for convenience of opening / closing operation on the indoor side, but the knob exposed on the surface of the indoor side finding piece 3a is connected to the supporting side so as to be movable up and down. If the side can be opened and closed on the indoor side, as shown in FIG.
May be supported by

When the opening / closing plate 9 is rotatably supported by either the first section 2 or the second section 3, the opening / closing plate 9 is blind so as to close the ventilation opening 4 a of the prospective piece 4 when closed. Since a plate is used, the opening / closing plate 9 is not necessarily closed
It is not necessary to overlap between the outside air introduction port 8 and the ventilation port 4a as shown in FIGS. 6 to 8, or between the outside air introduction port 7 and the ventilation port 4a as shown in FIG. It is only necessary to be able to shut off the outside air.

In the case of FIG. 10, the opening / closing plate 9 is brought into close contact with any part of the first profile 2 from the upper surface side or the lower surface side, so that the outside air is introduced between the outdoor outside air introduction port 7 and the ventilation port 4a. Cut off.

FIGS. 6 to 8 show a case where a knob 11 is connected to the opening / closing plate 9 at the center in the length direction of the ventilation frame 1 and the opening / closing plate 9 is opened / closed by operating the knob 11. Opening / closing plate 9
May be continuous over the entire length of the ventilation frame 1, or may be divided on both sides in the longitudinal direction at the position of an operation box 13 described later. In the latter case, the divided open / close plates 9, 9 are connected by a holding member 11a described later, and are linked with the operation of the knob 11.

In FIGS. 6 to 8, an operation box 13 for restricting the movement range of the knob 11 is fixed to the center of the indoor outside air inlet 8 which is open on the indoor side.
It is movable in the longitudinal direction with respect to the opening and closing plate 9 within the

In the case of FIGS. 6 to 8, the operation box 13 is exposed on the surface of the indoor side finding piece 3a. Therefore, when the ventilation frame 1 is cut off, it is cut at any position other than the installation position of the operation box 13. can do.

An example of the combination of the ventilation frame 1 with the upper frame 22 and the lower frame 23 when incorporating the ventilation frame 1 into a shoji as shown in FIG. 13 will be described. At the upper end of the first section 2 or the lower end of the second section 3,
In order to cope with the difference in the expected width of the upper frame 22 and the lower frame 23 holding the ventilation frame 1, the gasket 17 to be mounted on the upper frame 22 or the lower frame 23 as shown in FIG. Upper frame 22 or lower frame as shown in FIG.
An attached portion 19 for attaching the spacer 18 held by 23 is formed. The attached portion 19 is formed at the upper end of the first section 2 when the ventilation frame 1 is held by the upper frame 22, and is formed at the lower end of the second section 3 when held by the lower frame 23.

FIGS. 1 to 3 show a case where an attached portion 19 having a shape corresponding to the gasket 17 is formed at the upper end of the first section 2. The gasket 17 is mounted on the mounting frame 19 so as to sandwich the mounting portion 19, and the upper frame 22 holds the ventilation frame 1 by holding the gasket 17 in the groove for holding a panel made of glass or the like. The protruding length and shape of the attached portion 19 from the upper end of the first section 2 are not limited as long as it is sandwiched and held by the gasket 17.

Since the expected width of the upper frame 22 and the lower frame 23 corresponds to the expected width of the vertical frame, the gasket 17 is also provided on the small caps 6 attached to both ends of the ventilation frame 1 as necessary as shown in FIG. A mounting portion 19 to which the spacer 18 is mounted is formed.

The upper frame 22 and the lower frame 23 are joined to the vertical frame by screws at both ends in the longitudinal direction, and the ventilation frame 1 is held via the gasket 17 in order to maintain the state where the ventilation frame 1 is held. Sometimes it is not necessary to hold it to the extent that it is connected to the ventilation frame 1.

As shown in FIG. 3, the distance between the surfaces on both sides of the gasket 17 in the expected direction is from the side of the ventilation frame 1 to the upper frame 22 and the lower frame 23.
Because it becomes smaller toward the side, the gasket 17 is moved from the upper frame 22 and lower frame 23 of the inner law corresponding to the maximum expected width,
It is possible to correspond to the upper frame 22 and the lower frame 23 of the internal law corresponding to the minimum expected width.

FIGS. 4 and 5 show a case where an attached portion 19 having a shape corresponding to the spacer 18 is formed at the upper end of the first section 2. The spacer 18 is also attached thereto so as to sandwich the attached portion 19, and the upper frame 22 holds the ventilation frame 1 by holding the spacer 18 in the swallowing groove.

In FIGS. 4 and 5, the mounting portion 19 is formed in a shape having a concave portion on both sides in the expected direction, and the spacers 18 are mounted on the mounting portion 19 in pairs. Since the inner frame is held by the upper frame 22 and the lower frame 23 corresponding to the distance, if the spacer 18 holds and holds the mounted portion 19 in this case as well, the shape of the mounted portion 19 and the spacer
The shape of 18 is not asked.

In the case where the surface of the spacer 18 is flat as shown in the figure, the spacer 18 having a different distance between both surfaces is attached to the mounting portion 19 with respect to the upper frame 22 and the lower frame 23 having different inner methods. However, if the spacer 18 itself has the same shape as the gasket 17 described above, it is not necessary to use the spacer 18 having a different distance between both surfaces, and the single spacer 18 does not require the upper frame 22 having a different inner law. And lower frame 23.

FIGS. 6 to 8 show a lower frame at the lower end of the second section 3.
An example in which a held portion 20 held by 23 is formed is shown.
Here, the holding part 20 is a parallel piece that is parallel to the prospective direction.
Is formed and is held in the lower frame 23 of the specific expected width. In this case, the parallel pieces are separated from each other by such a distance that the lower frame 23 and the upper frame 22 are inscribed.

9 and 10, the held portion 21 is formed at the upper end of the first section 2 so that the expected width decreases from the upper end side of the first section 2 to the upper frame 22 side. Here is an example of the case. In this case, since the held portion 21 has the same shape as the gasket 17, the gasket 17 and the spacer 18
It is possible to cope with the upper frame 22 having a different expected width without attaching the frame. FIG. 10 shows a case where the held portion 21 is formed in a step shape.

FIGS. 11 and 12 show another example of the configuration of the ventilation frame 1 held by the upper frame 22 and the lower frame 23 of a specific expected width. Here, the prospective piece 4 is inclined so that it can be seen from the indoor side, and FIG.
5, an opening / closing plate 9 provided with a ventilation opening 9 a that can match the ventilation opening 4 a is arranged on the lower surface side of the prospective piece 4, and the opening / closing plate 9 is arranged in the length direction along the prospective piece 4 as in FIG. 5. Moveable first
A filter 10 is placed on the upper surface side of the prospective piece 4 while being supported by the profiled material 2 and the second profiled material 3. ing.

In this example, since the prospective piece 4 stands up from a horizontal state and faces the indoor side, the knob 11 for operating the movement of the opening / closing plate 9 is not the indoor side finding piece 3a but the prospective piece 4
Is connected to the opening / closing plate 9. Figure 11- (a), Figure
12- (a) shows the ventilation frame 1 held by the upper frame 22, and FIG. 11- (b)
12 (b) shows the ventilation frame 1 held by the lower frame 23. FIG.
