Description

[Detailed Description of the Invention] Technical Field The present invention relates to a louver that is attached to buildings etc. for the purpose of ventilation.

PRIOR ART It is well known that a conventional louver, which can be opened and closed to ventilate as needed, has a plurality of blades rotatably attached to a frame in parallel with each other. Rotate the blades to open them to let the wind through, and close them to block the wind. This louver has not been widely used in residential buildings in the past. The main reason for this is that the interior of the room can be seen through the louvers when ventilation occurs.

By the way, it is well known that many housing complexes such as condominiums and apartments are currently being built, but in these housing complexes, windows are only on the wall facing the hallway and the wall on the opposite side, excluding the rooms at both ends. Not provided. Therefore, it was necessary to install a window on the hallway side, but since it faces the hallway, it is not possible to leave it open for ventilation. Additionally, it was necessary to install a security grill on the top, and it was also desired to install storm shutters to block light at night. Furthermore, it needs to be blindfolded to allow ventilation, but conventional louvers could not be used here for the reasons mentioned above. Additionally, there may not be enough room to install shutters.

As mentioned above, in the past, there was nothing attached to the window to allow ventilation while blocking the line of sight, and to also serve as a screen lattice or shutter.

Purpose of the invention The present invention was made taking these points into consideration, and provides a multifunctional louver that can allow ventilation while blocking the line of sight, and can also serve as a shutter and a lattice. The purpose is to

Summary of the invention This invention is a system in which a plurality of slats are attached to a frame parallel to each other so that they can be opened and closed, and when the slats are closed, the side ends of the slats directly or indirectly abut each other. This is characterized in that blinding plates made of a translucent material or an opaque material are attached to both sides of the slats so that they are not on the same surface.

In this specification, the term "semi-transparent" means something that blocks visible light from going straight and allows it to pass through in a scattered state, and cannot be seen directly through it. In addition, opaque refers to something that does not transmit visible light.

Embodiment As shown in FIG. 1, the louver of the present invention has a plurality of blade plates 10 rotatably attached to a frame body constituted by an upper frame 11, a lower frame 12, and a vertical frame 13. In this embodiment, the blade plate 10 is attached vertically to the frame, but it is also possible to attach it laterally.

The structure of the vane plate 10 of this embodiment is as shown in FIG. The main body 14 of the blade plate 10 is made of a shaped material such as an aluminum alloy, and has a substantially rectangular cross-sectional shape. Fitting grooves 16, 16 for fitting the blindfold plate 15 on both the front and back surfaces thereof
is formed. This main body 14 is hollow,
The interior is filled with glass wool or filled with urethane foam to improve sound insulation.
An upper member 17 and a lower member 1 are attached to the upper and lower ends of this main body 14.
8 is attached, while the sleeves 1 are attached to both sides.
9 and 20 are provided so as to protrude.

One sleeve portion 19 is a plate-shaped body that extends one surface of the main body 14 and has a slightly rounded tip, and the other sleeve portion 20 is a plate-shaped body that extends one surface of the main body 14 as it is and has a slightly rounded tip.
A side surface 14a is located near the surface opposite to the surface on which 9 is formed.
It is a plate-shaped body formed at right angles from the bottom, and a packing holding part 22 for holding a packing 21 is formed at the tip. Both sleeve portions 19 and 20 are connected to each other by attaching the slat 10 to the frame body, and when the slat 10 is closed, as shown in FIG. This is for abutting against the gasket 21 of the portion 20. Although the sleeve portions that form the side ends of the slats may be in direct contact with each other in this way, it is also possible to provide a vertical crosspiece at this contact point and indirectly abut both sleeve portions through this vertical crosspiece. You can do it like this.

The upper member 17 has a plug member 24 formed on one side of the upper plate 23 that covers the upper end of the main body 14 and has a shape that can be fitted into the hollow part at the upper end of the main body 14, and has a rotation center and a center of rotation on the opposite surface. A shaft 25 is attached. Further, tight pieces 23a and 23b are provided upright on this surface to tighten the gap between the upper member 17 and the upper frame 11. The tight pieces 23a and 23b are formed so as to be offset to such an extent that a tight material 45 provided on the upper frame, which will be described later, can be sandwiched therebetween. The plug member 24 is made of synthetic rubber, synthetic resin, or the like. A pinion 26 for rotating the blade plate 10 is attached to the shaft 25. This pinion 26 is meshed with a rack 44 mounted within the upper frame 11 as will be described later, and is used to rotate the main vane by moving the rack.

Similarly, the lower member 18 has a plug member 2 on one side of the lower plate 27.
In addition to forming a plug member 28 similar to 4, an auxiliary plug member 29 that can be inserted from the lower end of the blind plate 15 is also formed. Therefore, lower plate 2
7 is shaped so that this auxiliary stopper member 29 can also be placed thereon. A shaft 30 serving as the center of rotation is attached to the surface opposite to the surface to which the plug member is attached.

It is desirable to attach a plug member 29a similar to the auxiliary plug member 29 to the upper end of the blind plate 15.
This upper plug member 29a includes a plug portion 29b and a flange portion 2.
9c and a guide portion 29d that is inserted into the fitting groove 16 and guided.

As shown in FIG. 3, the blind plate 15 has an elongated U-shaped cross section, with a reinforcing plate 31 interposed in the middle. The auxiliary plug member 29 and plug portion 29b
A length that can be inserted into the space from the fitting groove 16 to this reinforcing plate 31 is sufficient. The blind plate 15 is made of a semi-transparent material such as weather-resistant PVC or acrylic, but may be made of an opaque material. Both ends of the U-shape have sharpened ends, and have locking portions 32 that are inclined outward from each other and protrude from the surface. The slat main body 1
The fitting groove 16 formed in 4 is formed by projecting ridges 33, 33 on which the locking portion 32 is hooked, and projecting inwardly from each other. Therefore, in order to attach the blind plate 15 to the vane plate 10, since the blind plate itself is elastic, the locking parts 32, 32 are placed in the fitting groove 16, and when pushed strongly, the locking parts 32, 32 are attached to the fitting groove 16. It can be placed inside and fitted. To remove it, push the parts beyond the reinforcing plate 31 closer together to separate the locking part 32 from the protrusion 33 and take it out. Of course, the upper and lower members 17, 1 of the main body 14
8 and insert the locking part 32 into the fitting groove 16 from above or below.
You can also insert it inside and slide it. If a non-elastic material such as glass is used as the blindfold plate 15, it must be attached by sliding it as described above. This blind plate 15 is fixed by an auxiliary plug member 29 of the lower member and an upper plug member 29a attached as necessary.

Next, the attachment of this wing board 10 to the frame will be explained.

As shown in FIG. 6, a sash 36 for a shoji is attached to an opening 35 in the wall 34,
A frame body framed by an upper frame 11, a lower frame 12, and a vertical frame 13 is attached to the front surface of 5. The blade plate 10 is rotatably attached to an upper frame 11 and a lower frame 12 of this frame body. The frame of this embodiment as a whole, that is, the louver of this embodiment is
It is said to be removable. Therefore, on the upper side of the upper frame 11, there is a hanging part 39 shaped so that it can be hung on a hook member 38 fixed to the wall 34 with an anchor 37.
A wall 3 is formed at the bottom of the lower frame 12.
A protrusion 43 is formed to be latched onto a latch 42 of a lower frame latch 41 attached to the lower frame latch 41. The shafts 25 and 30 are inserted into holes provided in the upper frame 11 and the lower frame 12 to attach the blade plate 10 to the frame body.
Inside the upper frame 11 is a pinion 26 attached to a shaft 25.
A rack 44 that engages with the housing is slidably housed. Further, a tight member 45 is attached to the upper frame 11 and is sandwiched between tight pieces 23a and 23b formed on the upper member 17. A tight material 45 is similarly attached to the lower frame 12 and is similarly tightened with the lower member 18. This tight material 45
is made of PVC.

The lower frame latch 41 is as shown in FIG. 7, and the latch 42 is slidably housed in a groove 47 formed parallel to a fixing part 41a attached to the wall.
The lower end 42a of this latch 42 and the notch 4 of the side part 48
The protrusion 43 of the lower frame 12 is inserted between the lower frame 8a and the lower frame 12 to stop the lower frame. Therefore, in the louver of this embodiment, as a whole, the hanging part 39 is hung on the hook member 38, and the protrusion 43 of the lower frame is placed on the cutout part 48a.
2 can be attached to the wall by lowering it. Naturally, the whole can be removed by pulling up this latch 42. Since this latch 42 is provided on the indoor side, the main louver cannot be removed from the outdoors.

FIG. 4 shows how the slats 10 are attached to the frame, and as described above, the sleeves of adjacent slats 10 are brought into contact with each other and closed. One vertical frame 13
A plate part 13a is formed on the other vertical frame to hold the seal 21 against which the sleeve part 19 comes into contact, and a seal receiver 13b is formed on the other vertical frame to hold the seal 21 against which the sleeve part 19 comes into contact. The spacing between adjacent vanes is such that a person cannot enter or exit the vane no matter which rotational position the vane is in. A handle 49 for opening and closing the entire vane is attached to the lower frame side of the central one of these vanes 10. As shown in FIG. 8, this handle 49 has one end inserted into a cover 50 and is swingable. This handle 49 also serves as a fixing means for fixing the open/closed state of the blade plate, and when the handle 49 is returned to a parallel state to the main body 14, a rod 51 provided inside protrudes toward the lower frame side. It is designed to be fixed by being inserted into one of the holes 53 bored in a lock receiving plate 52 provided in the lower frame 12. When opening, the handle 49 is set at 90 degrees with respect to the main body 14 as shown by the two-dot chain line, the rod 51 is removed from the hole 53, and the blade plate 10 is rotated by holding it.
In this embodiment, three holes 53 are bored in the plate 52 so that it can be fixed in three positions: closed, 45° open, and 90° open (FIG. 5). The opening/closing state fixing by the handle 49 is not limited to the one shown in the drawings, and a normal door french locking mechanism can be used as is.

In this embodiment, as described above, the handle 49 for opening and closing the vane board 10 is provided only on one vane board, and is not provided on the other vane board. The mechanism that opens and closes all the vanes 10 at the same time by opening and closing one vane is the mechanism using the rack 44 and pinion 26 described above. The rack 44 is a long rack that is slidably housed in the upper frame 11, and the pinion 26 of each blade plate 10 is engaged with this rack (9th rack).
figure). FIG. 9A shows the meshing state with the blades closed. At this time, when the pinion 26-1 of the blade plate to which the handle 49 is attached is rotated by the handle in the direction shown by the arrows in B and C in the figure, the rack 44 moves to the left side in the drawing, and the rack 44 moves to the left side in the drawing. Due to the movement, other pinions, for example 26-2, also rotate in the direction of the arrow. It will be readily understood that all pinions engaged with rack 44 rotate together. B is 45° open and C is 90° open. When closing, the rack 44 can be moved and the entire vane can be closed by rotating one of the vanes in the opposite direction, as shown in FIGS. As described above, the entire blade plate 10 can be opened and closed using the handle 49.

The closed state is shown in FIG. 4, and the 90° open state is shown in FIG. The slats 10 are opaque, and when closed, the side edges of the slats abut against each other, so that in the state shown in FIG. 4, it can function as a shutter. Moreover, when opened as shown in FIG. 5, since the blindfold plates 15 are attached to the main body 14 with deviations on both sides, the blindfold plates 15 facing each other as shown in the figure,
A gap is created between 15, and wind can pass through this gap as shown by the arrow. This blindfold board 15
Since it is semi-transparent, it is not possible to see into the room from the outside, but it is possible to let in light. In other words, ventilation can be achieved while blocking the line of sight into the room. In addition, when the blindfold plate is made of an opaque material, ventilation can be provided in a non-lighting state.

Modification FIG. 10 shows another embodiment, in which the main body 54 has an elongated oval shape, and the blind plate 55 has a single plate shape. There is no particular difference from the previous embodiment except for the shapes of the vane plate and the blind plate.

Effects of the invention As described above, in this invention, the opaque slats can be opened and closed freely, and both ends are in contact with each other, so it can be used as a rain door. Since they are installed offset, ventilation can be achieved while blocking the view from the outside. Furthermore, it can function as a surface grid in a ventilated state.
