Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an opening exterior device arranged in an opening of a building.

[0002]

[Prior Art] At the opening of apartments such as condominiums,
At present, double sashes are often installed, but shutters were not usually installed. The main reason for this is that if the shutter is installed without a space for accommodating the shutter such as a door pocket, the lighting of the opening is sacrificed.

[0003]

However, even in the opening portion to which the double sash is attached, the following disadvantages remain. Although internal insulation is possible by hanging curtains, blinds, etc. inside the glass shoji screen against the sunlight coming from the opening, it is not possible to achieve external insulation that is insulated from the outside of the building. is there. There is also data that the insolation penetration rate for inner insulation is about 47%, while the insolation penetration rate for outer insulation is only about 18%. In the case of inner insulation, it is proportional to the insolation penetration rate. As a result, the operating rate of the air conditioner increases, which is a negative factor for energy conservation. Also,
Blinds and curtains alone may not be enough to protect resident privacy and crime prevention.

In view of this, an object of the present invention is to provide a shutter that can maintain the original functions of the shutter for windproofing, rainproofing, and crime prevention, as well as ensure the daylighting property and can be insulated from the outside.

[0005]

In order to solve the above problems, in an opening exterior device in which at least two shutters are attached to a shutter frame formed in the opening of a building, the shutter frame of each shutter has: At least one set of a plurality of slats is arranged to be openable and closable, and the shutter is slidably attached to the shutter frame with the slats of the shutter open (the invention of claim 1). . According to this invention,
Since the shutters are attached to the shutter frame so that the shutters can be slid while the slats of the shutters are opened, the slats of the inner and outer shutters can be opened in a high lighting condition to secure the lighting performance. Therefore, the original functions of the shutter, such as windproof, rainproof, and crime-preventive functions, can be exerted, and external heat insulation and privacy can be protected.

In the above invention, the mesh member for covering the frame surface of the shutter may be attachable (the invention according to claim 2). The existing exterior door of the opening can be removed and the opening exterior device of the present invention can be attached.

In the above invention, the shutter door frame can be retrofitted to the opening, and the shutter can be attached to the opening of the existing building (the invention according to claim 3).

In the above invention, the shutter frame can be integrally formed with the opening, and the shutter can be attached to the opening of a new building (the invention according to claim 4).

In the above invention, the swing mechanism for swinging the plurality of slats so as to be openable and closable is provided with a torsion bar for converting a sliding force into a rotational force, and is attached to one end side of the torsion bar and the rotational force thereof is provided. And a bar member attached to the first transmission member and transmitting the rotational force thereof, and a predetermined distance between the bar member so as to correspond to the plurality of slats. And a second transmission member which is attached at a position and to which the rotational force of the bar member is transmitted (the invention according to claim 4). According to the present invention, the slat can be opened and closed at an arbitrary angle with a simple operation.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of an opening exterior device according to the present invention will be described with reference to the drawings. 1 is a front view of the outdoor side of the shutter, FIG. 2 is a longitudinal sectional view thereof, and FIG. 3 is a transverse sectional view thereof. In addition, in each of the above-mentioned drawings and each of the following drawings, the substantially same configurations are denoted by the same reference numerals and detailed description thereof is omitted.

The opening exterior device includes a set of a plurality of slats 2 ... on a shutter frame B attached to the opening A of the building.
The inner and outer shutters 1 and 8 that are arranged so as to be openable and closable are assembled so that they can be pulled even when the slats 2 are open. Therefore, since the slats 2 of the outer shutter 8 are fully opened and the slats 2 of the inner shutter 1 are fully opened at the same time, the inner and outer shutters 1 and 8 can be positioned so as to be overlapped with each other. It is possible to secure the daylighting property of the opening A without requiring a space for housing. In addition, in a state in which the opening A is closed by the inner and outer shutters 1 and 8 and the slat 2 is opened to secure the daylighting, outer heat insulation can be achieved and privacy protection can be achieved. Further, even when the opening A is closed by the inner and outer shutters 1 and 8 and the slats 2 of the inner and outer shutters 1 and 8 are opened,
Since the opening A can be opened by pulling either the indoor or outdoor shutters 1 and 8, there is no problem in escaping in an emergency such as a fire.

In the shutter door frame B, an opening frame B5 is formed by left and right vertical frames B1 and B2 and upper and lower horizontal frames B3 and B4, and a movable area B6 in which the inner shutter door 1 can be moved, A movable area B7 in which the outer shutter 8 can move,
Between these areas B6 and B7, the slats 2 of the inner shutter 1
Is provided with a pulling region B8 that allows the sliding doors 1 and 8 to slide even when the shutters are fully opened.

An upper frame B above the movable areas B6 and B7
Lower open U-shaped parts B30 are formed on the respective parts 3, and rail parts B80 are formed on the lower frame B4 of the lower part, respectively, so that the inner and outer shutters 1 and 8 are formed so that they can travel. Further, the upper frame B3 cooperates with an insect-proof fin 123 of the inner shutter 1 to be described later to prevent insects from entering the insect-proof frame B81.
On the other hand, a convex portion B82 is formed on the lower frame B4 by being sandwiched by the rail portion B80. The width W of the pull-in area B8 may be approximately the same as the maximum width W1 when the slats 2 of the inner shutter 1 are opened, or may be a dimension with some play. Therefore, when the shutter door frame of the inner shutter 1 is formed so that the width W2 of the slats 2 of the inner shutter 1 when opened can be accommodated, the pulling region B8 is unnecessary. In addition, "B9" indicates mohair and "B10".
What is shown is a glass shoji. In this embodiment, 2
Although the opening exterior device is attached to the outside of the glass shoji sheet, the opening exterior device may be attached to the outside of the double sash made of four glass shoji.

Next, a structural example of the inner shutter 1 will be described with reference to FIGS. 2 and 3. This inner shutter 1 has an upper and lower frame 10,
11, a left and right frame 12, 13 forms a shutter frame, and a plurality of slats 2 are horizontally arranged along the frame surface, and a bar-shaped portion 1 arranged above the lower frame 11
An operation slider 15 for operating a swinging mechanism (described later) is exposed to 4 and a mesh member 17 for covering the frame surface is attached. Then, the operation slider 15
When slid in the left-right direction on the surface of FIG. 3, the slats 2, 2, 2 ... Swing to open and close.

The upper frame 10 is slidably assembled along the lower open U-shaped part B30 of the upper frame B3, while the door frame 110 is attached to the lower frame 11 so that the upper frame 10 can run on the rail part B80. It is like this. The vertical frame 12,
Buffer members 120 and 130 are attached to the portions of the shutter frame B that are in contact with the vertical frames B1 and B2, respectively.
Part of the swing mechanism is housed in the hollow portions 121 and 131 of the third housing. Further, as shown in FIG. 3, the vertical frame 1
Light-shielding pieces 122 and 132 are formed on the indoor sides of 2 and 13, respectively. This is because when the slats 2 that can be swung open and closed are attached to the left and right vertical frames 12 and 13, a slight gap is formed at both ends of the slats, and light from the outside and light from the indoor side leak. This is to prevent this.

The vertical frame 12 has a vertical dimension from a position in contact with the insect-proof frame B81 of the shutter frame B to a position in contact with the convex portion B82 of the shutter frame B, and the width W of the pulling region B8.
An insect-repellent fin 123 having a lateral dimension substantially corresponding to is formed. "124" and "134" are the vertical frame 12,
13 is a handle portion provided.

The bar-shaped portion 14 is a part of the swinging mechanism incorporated, and the operation slider 15 is exposed to the inside of the room as described above, and the mesh member 17 is mounted on the upper portion thereof. The piece 140 is formed.

The mesh member 17 is formed by knitting a metal thread or a synthetic resin thread, for example, a thread of polyester resin or the like. The upper frame 10 and each of the attachment grooves 170 provided on the attachment piece 140 of the cross section 14 are attached via the rod member 19. The rod member 19
Is a synthetic resin having a circular cross-sectional shape and elasticity, and is molded into a hollow shape so as to be easily attached and detached. On the other hand, the groove 170 is formed with a protrusion 171 for preventing the stick member 19 from coming off. Therefore, by removing the rod member 19 from each of the attachment grooves 170, the mesh member 17 can be removed, only the mesh member 17 can be washed, and can be removed in a season when insects do not occur.

Next, a structural example of the swing mechanism will be described with reference to FIGS. 4B to 8. As shown in FIGS. 4B and 5, the swing mechanism includes a torsion bar 3 that converts the sliding force of the operation slider 15 into a rotational force, and a first transmission member that transmits the rotational force to the bar member 4. 5 and a second transmission member 6 that transmits the rotational force of the bar member 4 to each slat 2.

The operation slider 15 has a knob 150.
And a slider body 151, and the slider body 151 is a slide frame 14 provided on the crosspiece 14.
2 (FIG. 4B) so as to be linearly slidable.

A structural example of the slider body 151 will be described with reference to FIG. The slider main body 151 includes a main body 151a, a lid 151b, and a crimp 151c for assembling the main body 151a and the lid 151b, and the knob 150 is fixed to the crimp 151c. The main body 151a includes two rows of holes 151.
d and 151d are provided, and a spring 151e and a ball 151f are fitted in each hole 151d. The body 151a and the lid 151b are provided with a twisted hole 152. The clearance formed in the hole 152 is urged toward the lid 151b by the spring 151e. Ball 151f
Adjusted by Therefore, the slider body 151
It can be slid smoothly without any rattling.

The reason why the "rattle prevention means" is attached and the function thereof will be described in more detail with reference to FIG. When the twisted hole 152 is formed faithfully along the “twist” of the twist bar 3, when the operation slider 15 is operated,
"Backlash" occurs. Further, it is difficult to form the same "twist" in all the torsion bars 3. Therefore,
The twisted hole 152 requires a clearance (play) for the twist bar 3. In this case, the "backlash prevention means" adjusts the clearance and realizes a comfortable slide operation.

As shown in FIG. 7, the spring 15
The ball 151f, which is urged toward the lid 151b by 1e, comes into contact with the torsion bar 3 and is rotated by sliding the operation slider 15. As a result, the clearance C acting on the torsion bar 3 is appropriately adjusted, and the slider body 151 can be smoothly slid without causing "backlash". The slider body 151 may have any shape as long as it can slide linearly along the slide frame 142, and the knob piece 150 of the spoiler 15 may also have any shape. Good.

The twist bar 3 is formed by deforming a thin plate-shaped bar material at a predetermined twist angle, and is adapted to rotate normally or reversely depending on the sliding direction of the operation slider 15. The twist angle of the twist bar 3,
That is, the rotation angle of the other end 31 with respect to the one end 30 of the torsion bar 3 formed by the twist angle allows the operator to lightly slide the operation slider 15 and enjoy a desired opening / closing angle. It may be molded so that the opening / closing angle of 2 can be finely adjusted. For example, as shown in FIG. 8, with respect to the length L from one end 30 to the other end 31 of the torsion bar 3, the rotation angle at the other end is about 210.
You may shape like a degree. With the same size L, the larger the rotation angle is set, the larger the opening / closing angle of the slat 2 can be made, but a large sliding force must be applied, and the operability becomes heavy. On the other hand, the smaller the rotation angle is set, the smaller the opening / closing angle of the slat 2 becomes and the lighter the operability becomes. Further, by adjusting the mounting length of the torsion bar 3 at the same rotation angle, the slats 2 can be adjusted according to the slide width of the slide bar 15.
The opening and closing angle of can be adjusted.

In this embodiment, the mounting length of the torsion bar 3 is set so that each slat 2 can be opened and closed within a range of about 90 degrees, and both ends 30, 31 of the torsion bar 3 are attached to the rotary shafts 32, 32. It is fixed and these rotary shafts 3
Reference numerals 2 and 32 are attached to bearings 33 and 33 fixed to the slide frame 142, respectively.

As shown in FIG. 5, the rotary shaft 32 includes a fixed cylindrical portion 320 for fixing the end portion of the torsion bar 3 and a rotating portion 321 having a diameter reduced from the fixed cylindrical portion 320. Become. A square hole 322 for fixing one end of the first transmission member 5 is formed in the rotating portion 321. The step 323 formed between the fixed columnar portion 320 and the rotating portion 321 abuts the side surface of the bearing 33, so that the torsion bar 3 idles without displacement,
Only the rotational force is transmitted to the first transmission member 5. By interposing the rotary shaft 32 between the torsion bar 3 and the first transmission member 5, the torsion bar 3 can be smoothly rotated, and the torsion bars 3 having different torsion angles can be easily replaced. The rotating portion 321 of the rotating shaft 32 has a hole (not shown) provided in the vertical frame 12.
From above, it is projected into the hollow portion 121 (see FIG. 3) of the vertical frame 12 and is connected to one end 50 of the first transmission member 5.

The first transmission member 5 is housed in the hollow portion 121 of the vertical frame 12, and one end 50 thereof is arranged substantially on the same axis as the torsion bar 3 and the rotary shaft 32, as shown in FIG. And is fixed to the square hole 322 of the rotary shaft 32. The other end 51 rotates around the one end 50 in accordance with the rotation of the torsion bar 3. The first transmission member 5 is formed in a substantially oval shape, but the one end 50
Any shape may be used as long as it has a rotation center portion corresponding to (4) and a rotation portion corresponding to the other end 51.

The other end 51 of the first transmission member 5 is attached to the hole 40 of the bar member 4 arranged along the hollow portion 121 of the vertical frame 12 so as to rotate freely. The bar member 4 rotates each slat 2 in synchronism with the rotation from the first transmission member 5, and has holes 41 corresponding to the arrangement interval of each slat 2 (see FIG. 5). .
On the other hand, one end 60 of the second transmission member 6, which has a shape substantially the same as that of the first transmission member 5, is formed so as to correspond to the hole 41 of the bar member 4 via a slat holder 7 described later. It is rotatably arranged in the vertical frame 12 (see FIG. 5 and the like). The other end 61 of the second transmission member 6 is arranged in each of the holes 41 of the bar member 4 so as to be able to rotate idly, and the second transmission member 6 has the one end 60 as a center.
It rotates in synchronization with the transmission member 5 of.

The slat holder 7 is, as shown in FIG. 5 and the like, the rotary shaft 7 facing the hollow portion 121 of the vertical frame 12.
0, a flange portion 71 that is coaxially fixed to the rotating shaft 70 and abuts on the outer surface of the vertical frame 12, and a wedge portion 72 that is embedded in the side surface of the slat 2.

A slat holder 7A (see FIG. 3) for rotatably holding the other end of the slat 2 is attached to the vertical frame 13 and is constructed in the same manner as the slat holder 7 and has a wedge portion. 72 is embedded in the side surface of the slat 2. As described above, the operation slider 1
5, the torsion bar 3, the bar member 4, the first transmission member 5, and the second transmission member 6 are attached to the vertical frame 12 side, but may be attached to the vertical frame 13 side.

Next, a structural example of the slat 2 will be described. As shown in FIG. 5 and the like, the slat 2 includes a hollow portion 21 provided with a mounting portion 20 for mounting the wedge portion 72 of the slat holder 7, and a plate-like portion extending downward from the lower portion of the hollow portion 21. 22 and is formed by extrusion molding of a metal material such as aluminum. This slat 2
The main characteristic point of this is that when the slat 2 is rotated to a substantially horizontal position, the upper part of the slat 2 is the light shielding piece 12 of the vertical frames 12, 13.
2, 132 (see FIG. 3), and the shape of the slat holder 7 has been devised so that the position of the rotating shaft 70 of the slat holder 7 and the center of gravity of the slat 2 substantially coincide with each other. That is, the sound deadening member 23 is attached to the outside of the upper chamber of the hollow portion 21.

In order to avoid interference between the light blocking pieces 122 and 132 and the upper portion of the slat, the size of the hollow portion 21 of the slat 2 is set to the rotation center of the slat 2 (the second transmission member 6).
One end 60, the rotation shaft 70 of the slat holder 7) and the light shielding pieces 122, 132 are formed to be shorter than the distance. In this case, the center of gravity of the slat 2 is the plate-like portion 2
If it is biased to the 2 side, the rotation of the slat 2 becomes heavy, which may impair comfortable operability. Therefore, a portion of the hollow portion 21 of the slat 2 that is closer to the light shielding piece from the center of rotation is formed to have a thick wall and a slight inclination so that the center of gravity thereof is not biased toward the plate portion 22 side. . As a result, the position of the rotating shaft 70 of the slat holder 7 and the center of gravity of the slat 2 are substantially coincident with each other, and the operability is improved.

The muffling member 23 is made of, for example, vinyl chloride, and when the slats 2 are closed, it muffles the sound generated when the upper and lower slats hit, and also exerts the function of rain.

The outer shutter 8 is different from the inner shutter 1 in that the insect fin 123 is not formed. The other structure is substantially the same as that of the inner shutter 1 and has substantially the same effect as the inner shutter 1.

Next, a shutter lock 9 for locking the inner and outer shutters 1 and 8 will be described. As shown in FIG. 4A, the shutter door lock 9 has a crescent main body 91 rotatably attached to a crescent fin 90 formed on the insect-repellent fin 123 of the inner shutter 1, and a chamber of the vertical frame 13 of the outer shutter 8 The crescent receiver 92 is fixed to the inside, and the handle 910 of the crescent body 91 is tilted toward the indoor side to be "opened", and when raised to the outdoor side, it is "closed".

As shown in FIGS. 1 and 2, the shutter frame B incorporating the shutters 1 and 8 configured as described above is formed into left and right vertical frames B1 and B2 and upper and lower horizontal frames B3 and B4. With the mounting fin B11 and the mounting piece B12 which are separate members from the shutter frame B,
A screen door frame or the like of the sash frame C as an opening is sandwiched and is fixed to the sash frame C by a binding means such as a halt and a nut. Further, the back side of the convex portion B82 of the lower frame B4,
It is supported by a supporting device C1 placed on the sash frame C. Therefore, when the shutter frame B is retrofitted to the sash frame C, the sash frame C on the building frame side is not damaged.

Next, the shutters 1 and 8 configured as described above.
An example of use of will be described based on FIGS. 9A to 9C and FIG. 10. 9 (a) and 9 (b) are cross-sectional views of a main part of the slat 2 in a closed state, and FIG.
The principal part sectional view of the state opened at 5 degrees is shown. FIG. 10 is a cross-sectional view of a main part side by side showing a state in which the slats 2 of the inner and outer shutters 1 and 8 are opened at approximately 90 degrees. When the slat 2 is in the closed state shown in FIGS. 9A and 9B, the operation slider 15 is at the right end position shown in FIG. When the operation slider 15 is slid to the left in the drawing from this position, the sliding force is applied to the torsion bar 3, the rotating shaft 32, the first transmission member 5, the bar member 4, the second transmission member 6, and the slat. Slat 2 via holder 7
And each slat 2 is opened at an angle corresponding to the slide width of the operation slider 15.

As shown in FIG. 9C, when the operation slider 15 is moved to the intermediate position, the slat 2 is half opened.

As shown in FIG. 10, when the operation slider 15 is slid further to the left end, the slats 2 are fully opened. At this time, when the indoor and outdoor shutters 1 and 8 are arranged to overlap each other as shown in FIG.
Since 80% can be secured and the inner and outer shutters 1 and 8 can be arranged so as to be overlapped with each other, half of the opening A is open, and sufficient lighting performance is obtained. When closing each slat 2, the operation slider 15 may be slid to the right.

According to the opening exterior device as described above, first, since the amount of light can be secured, the indoor and outdoor shutters 1 and 8 can be left in the opening A, and a door pocket or the like is not required. ,
There is no need to consider the space for that. Secondly, even when the slats 2 of the inner shutter 1 are fully opened, the inner and outer shutters 1 and 8 can be arranged in a sliding manner so that the slats 2
The opening A can be opened regardless of the open / closed state, and there is no problem even when a person goes in and out or in an emergency. Thirdly, by installing the indoor and outdoor shutters 1 and 8 in the opening A of the high-rise part of a high-rise apartment, it is possible to soften the occupant's sense of height from the windows. Fourthly, since the slats 2 are opened and closed by sliding the operation slider 15 to the left and right, the opening and closing operation is extremely easy, and the slats 2 are closed to prevent wind, rain, cold, and sound. Further, by adjusting the opening / closing angle, it is possible to achieve external heat insulation and protect privacy. Particularly, when the slats 2 are opened to about 45 degrees as shown in FIG. 9C,
Insulation, ventilation, and daylight can be realized at the same time.
Fifthly, the mesh member 17 attached to the shutter frame can prevent insects and the like from entering the room through the opening O. Sixth, by making the mesh member 17 detachable, the mesh member can be washed, replaced, and removed and stored in the winter when insects do not occur. Seventh, by reducing the twist angle of the torsion bar 3, the torsion bar 3 can be slid with a small force, and each slat 2 can be moved to about 90 degrees.
It can be fixed at any angle within a range of degrees. In this case, when it is desired to increase the opening / closing angle of each slat 2, the torsion bar having a larger twist angle may be replaced. Eighth, since the torsion bar 3 has a helix angle, even if the slat 2 is moved, the operation slider 15 does not easily slide, which is excellent in crime prevention.
Can reduce its manufacturing cost at low cost. Ninth, by forming the twist bar 3 by reversing the twist direction (counterclockwise), the slat 2 is moved when the operation slider 15 is at the position shown in FIGS. Can be opened. Tenth
In addition, the light-shielding pieces 122 and 132 are provided on the left and right vertical frames 12 and 13.
From this point, it is excellent in privacy protection and crime prevention.

By interposing a member for making the rotating direction of the rotating shaft 32 orthogonal to each other between the rotating shaft 32 and the first transmitting member 5, the operation slider 15, the torsion bar 3 and the rotating shaft 32 are provided. Can also be placed on the vertical side. Further, in the above-described embodiment, the slats are arranged on substantially the entire surface of the shutter frame, but the slats are limited to a predetermined area such as the upper part, the middle part, or the lower part of the shutter frame to rock the slats. A moving mechanism may be provided. In addition, the operation slider 150, on the indoor end of the shutter door frame,
