Abstract

The operability of a swinging mechanism for swinging slats is improved, and the functions such as circulation, ventilation, and lighting by an opening covering device are enhanced by the winging mechanism. Slats (2) are arranged horizontally in a rain shutter door frame composed of upper and lower stiles (10, 11), left and right stiles (12, 13), and a central stile (14). An operating slider (15) for operating the swinging mechanism faces to the central stile (14). The sliding force of the operating slider (15) is converted to a rotational force by a twisting bar (3) and transmitted to the slats (2) through a first transmitting member (5), a bar member (4), and a second transmitting member (6).

Description

TECHNICAL FIELD

The present invention relates to a swinging mechanism of slats and an opening covering device such as a rain shutter door utilizing the same.

BACKGROUND ART

An opening covering device is attached to the outside of an opening portion of a building. To give a concrete example, the opening covering device includes a rain shutter door, a folding rain shutter door, a double sliding rain shutter door, a sliding door, a casement window, a lattice window, a louver, a shutter, a window blind, a door, etc.
The opening covering device, in general, has functions of crime prevention, rainproof, windbreak and others. A material of the opening covering device has changed from wood to steel, from past to present.
Such opening covering devices have following technical tasks.
In the case of a rain shutter door, as functions of an inside glass window concerning crime prevention, rainproof and windbreak have been enhanced, there is a tendency that opportunities of using the rain shutter door is limited to the case such as a typhoon coming with a strong storm or an absence of long period from home. On the other hand, even if it is used frequently, there is a problem that a basic structure in which a rain shutter board is attached to a rain shutter door stile sacrifices airflow, ventilation and lighting.
Concerning opening covering devices except for the rain shutter door, in order to realize airflow, ventilation and lighting, there are a lattice window, a louver and others having slats attached to a stile as described in JP-A 55-32810 or JP-A 55-75087, for example.
However, they have problems as follows. An opening and closing angle of slats cannot be adjusted. Even if it can be adjusted, the adjustment range is limited. Even if it can be adjusted to any angle, the adjustment operation is not easy, or the swinging mechanism is complicated.
Therefore, an object of the present invention is to provide a swinging mechanism of slats that can be operated easily. Another object of the present invention is to improve operability of the swinging mechanism for swinging slats of an opening covering device. Concerning a rain shutter door, a folding rain shutter door, double sliding rain shutter door and others, still another object of the present invention is to provide a rain shutter door with a new function such as airflow, ventilation and lighting by attaching slats and a swinging mechanism thereof.

DISCLOSURE OF THE INVENTION

In order to solve the above-mentioned problems, according to the first invention, a swinging mechanism of slats is structured such that a swinging mechanism for swinging a plurality of slats includes a twisted bar for converting a sliding force of an operating slider, which is generated when an operator opens and closes the slats of an opening covering device from the inside, into a rotating force.
By using the twisted bar for a swinging mechanism, manufacturing cost is suppressed. In addition, the opening and closing of the slats become easy by the sliding movement of the operating slider. Furthermore, the slats can be opened or closed by any desired angle in accordance with a sliding width of the operating slider.
According to the second invention, a swinging mechanism of slats at least includes:
a twisted bar for converting a sliding force into a rotating force;
a first transmission member that is attached to one end of the twisted bar and to which the rotating force is transmitted;
a bar member that is attached to the first transmission member and to which the rotating force is transmitted; and
second transmission members that are attached to the bar member at a predetermined pitch corresponding to the plural slats and to which a force of the bar member is transmitted.
According to the present invention, the slats are opened and closed by the sliding movement of the operating slider in the horizontal direction, so easiness of the swing operation of the slats is improved.
According to the third invention, an opening covering device that is attached to an opening portion of a building, includes:
at least one set of plural slats arranged in a stile; and
a swinging mechanism for swinging the plural slats, the opening covering device including:
a twisted bar for converting a sliding force into a rotating force;
a first transmission member that is attached to one end of the twisted bar and to which the rotating force is transmitted;
a bar member that is attached to the first transmission member and to which the rotating force is transmitted; and
second transmission members that are attached to the bar member at a predetermined pitch corresponding to the plural slats and to which a force of the bar member is transmitted.
According to an opening covering device of the present invention, the following operational effects are attained. Airflow, ventilation, lighting, outside thermal insulation are realized, and protection of privacy can be secured. Since a twisted bar that converts a sliding force into a rotating force is used, a swinging mechanism can be housed compactly in a stile. By adjusting a twisting angle of the twisted bar, the sliding force that is applied and a swing angle of the slats (an angle of opening and closing) can be adjusted. The slats can be kept in a desired stable angle of opening and closing. Even if the slats are rotated in the state, the force is hardly transmitted to the operating slider.
The opening covering device means a device that is positioned at the inside of an opening of a building, that is facing the outside. Therefore it is not concerned whether or not fittings such as a window, a door, a paper sliding door or an entrance sliding door are positioned at the inside. For example, a window or an equivalent may or may not be positioned at the inside if a louver is used. Similarly, if a sliding door is used, the sliding door of the present invention can be used without any change. Otherwise, an entrance sliding door or others can be positioned at the inside of the sliding door of the present invention.
In the opening covering device according to the third invention, the twisted bar may be arranged in a central stile that constitutes the stile, other than in an upper stile, a lower stile, or the like, constituting the stile.
According to the present invention, a merit is obtained that an operator can operate the operating slider easily.
The opening covering device according to the third invention, may further include a first swinging mechanism for swinging the plural slats arranged above the central stile and a second swinging mechanism swinging the plural slats arranged under the central stile.
According to the operations of the first and the second swinging mechanism, the angle of opening and closing of the slats can be adjusted substantially the same or different between the upper and the lower portions with respect to the central stile.
In the opening covering device according to the third invention, a key device to be attached thereto is structured to have a lock body and a key lever that can be removed from the lock body when it is locked and engages the lock body when it is unlocked.
According to the present invention, the key lever can be removed from the lock body when it is locked. Therefore, the key device cannot be manipulated from the outside, so the crime prevention property is improved.
In the opening covering device according to the third invention, it is preferable to provide a prevention member for preventing an operating slider that applies a sliding force to the twisted bar from being operated from the outside.
According to the present invention, the disturbing member prevents the operating slider from being viewed from the outside and makes it difficult to be manipulated from the outside. Thus, the crime prevention property is improved.
According to the third invention, an upper stile that constitutes the stile has an adjustable height. Further, it is preferable that a rasp prevention member that supports a width of a rail groove can be attached to an upper stile that constitutes the stile. Furthermore, a roller device can support a rail structure that is provided to a frame.
When installing a rain shutter door of the present invention in not only in a newly build rain shutter door frame but also in an old rain shutter door frame, it is possible to install the rain shutter door by adjusting on the site without checking a height of the rain shutter door frame, a width of a rail groove, a rail structure and others in advance or without a precise measurement. Thus, the complicated work of the installation can be resolved.
Concrete examples of the opening covering device according to the third invention include a rain shutter door, a folding rain shutter door, a sliding door, a double sliding rain shutter door, and a lattice window.
In the opening covering device according the third invention, it is preferable to attach a net member along a stile surface. Thus, an insect-proof function is provided to the opening covering device.
A metal support of an opening covering device for preventing a sag of a frame is desirably used when the opening covering device is attached to the frame that is attached to a sash frame via a bracket. The metal support includes a main body that is attached to the backside of a lower frame of the sash frame and a screw that is fixed to the main body and can be rotated from a front side of the lower frame via a hole formed in the lower frame.
Further, a bracket, the metal support includes an upper hinge that is attached to the backside of a lower frame of the sash frame, a lower hinge that is attached to a base frame and a main body that is attached between the hinges.

BEST MODE FOR CARRYING OUT THE INVENTION

Rain shutter door 1 as oppening covering device

First, a basic structure of a rain shutter door as an opening covering device will be explained.
A rain shutter door 1, as shown in Figs. 1 and 2, includes a stile, i.e., a rain shutter door stile that is made of upper and lower stiles 10 and 11, left and right vertical stiles 12 and 13 and a central stile 14. Slats 2 are arranged in the horizontal direction of the rain shutter door stile, and an operating slider 15 for operating a swinging mechanism that will be explained later is disposed at the central stile 14.
When the operating slider 15 is moved to slide in the horizontal direction in Fig. 2, each of the slats 2, swings to open or close.
In this way, the swinging mechanism in which the slats 2 swing for opening or closing thereof is activated by the sliding movement of the operating slider 15 in the horizontal direction, so that easiness of the swinging operation of the slats 2 is improved.
As shown in Fig. 4 and other drawings, the operating slider 15 is housed within a width in the foresight direction for realizing a compact size. Therefore, handling of the rain shutter door 1 is also easy when it is stored in a door case or drawn out of the door case.

Swinging mechanism and twisted bar

The swinging mechanism, as shown in Figs. 3-7, includes a twisted bar 3 for converting a sliding force of the operating slider 15 into a rotation force, a first transmission member 5 for transmitting the rotation force to a bar member 4 and a second transmission member 6 for transmitting the rotation force (a displacement) of the bar member 4 to each slat 2.
The operating slider 15 includes a knob portion 150 and a slider body 151, which are arranged so that the slider body 151 can slide linearly along a slide frame 141 that is disposed at an inside concave 140 of the central stile 14.
The slider body 151 is provided with a slot 152 that is substantially parallel with the slide frame 141 (see Fig. 5, for example), and the twisted bar 3 is inserted into the slot 152.
The slider body 151 is formed substantially in a cube shape as shown in Figs. 3 and 4. However, it can be any shape such as an oval shape provided that it can slide linearly along the slide frame 141.
The twisted bar 3 is obtained by deforming a thin plate-like bar at a predetermined twisting angle and is structured to rotate in the forward or the reverse direction in accordance with a sliding direction of the operating slider 15.
The twisting angle of the twisted bar 3, i.e., a rotation angle formed between one end 30 and the other end 31 of the twisted bar 3 is preferably set so that an operator can slide the operating slider 15 and relish a desired angle of opening and closing of the slats 2 and that fine adjustment of the angle is possible for the slats 2.
For example, as shown in Fig. 8, the rotation angle of the other end with respect to a distance L between one end 30 and the other end 31 of the twisted bar 3 can be set to approximately 210 degrees.
Under the condition of the same distance L, the angle of opening and closing of the slats 2 can be set to a larger value as the rotation angle is set to a larger value. However, increasing the angles accompanies the necessity to apply a larger sliding force, which causes heavy operability. In contrast, as the rotation angle is set to a smaller value, the angle of opening and closing of the slats 2 becomes smaller and the operability becomes lighter.
In addition, under the condition of the same rotation angle, an attachment length of the twisted bar 3 may be adjusted so that the angle of opening and closing of the slats 2 can be adjusted.
In this embodiment, the attachment length of the twisted bar 3 is set so that each of the slats 2 can be opened and closed within the range of approximately 90 degrees. Both ends 30 and 31 of the twisted bar 3 are fixed to rotating shafts 32 and 32, which are attached to bearings 33 and 33 that are fixed to the slide frame 141.
The rotating shaft 32 includes a fixing cylinder portion 320 that fixes an end portion of the twisted bar 3 and a rotating portion 321 that has a diameter smaller than that of the fixing cylinder portion 320 as shown in Figs. 3, 4 and 7.
This rotating portion 321 is provided with a rectangular hole 322 for fixing an end of the first transmission member 5.
A step 323 formed at the boundary between the fixing cylinder portion 320 and the rotating portion 321 abuts a side face of the bearing 33, so that the twisted bar 3 can rotate freely without being displaced and only the rotation force can be transmitted to the first transmission member 5.
Furthermore, the rotating shaft 32 is disposed between the twisted bar 3 and the first transmission member 5 so that the twisted bar 3 can rotate smoothly and be easily replaced with another one having a different twisted angle.
The first transmission member 5, as shown in Fig. 4 and other drawings, has an end 50 that is arranged substantially coaxial with the twisted bar 3 and the rotating shaft 32, is fixed to the rectangular hole 322 of the rotating shaft 32, and has the other end 51 that rotates around the end 50 in accordance with the rotation of the twisted bar 3.
The first transmission member 5 is formed into substantially an oval shape (see Fig. 7 and other drawings), but can have any shape as long as it has a rotating center that corresponds to one end 50 and a rotating portion that corresponds to the other end 51.
As shown in Fig. 4 and other drawings, the other end 51 of the first transmission member 5 is attached to a hole 40 of a bar member 4 that is arranged along the vertical stile 13 so that it can rotate freely.
The bar member 4 is provided for allowing each of the slats 2 to rotate in synchronization with the rotation from the first transmission member 5, and is provided with holes 41 that are arranged at a spacing corresponding to the arrangement pitch of the slats 2 (see Fig. 7 and other drawings).
On the other hand, in correspondence with the holes 41 of the bar member 4, one end 60 of the second transmission member 6 that is formed in substantially the same shape as the first transmission member 5 is arranged in a rotatable manner to the vertical stile 13 via a slat holder 7 that will be explained later (see Fig. 6 and other drawings).
The other end 61 of this second transmission member 6 is arranged in each of the holes 41 of the bar member 4 so that it can rotate freely, and the second transmission member 6 rotates around one end 60 in synchronization with the first transmission member 5.
The slat holder 7, as shown in Fig. 7 and other drawings, includes a rotating shaft 70 that is disposed in the vertical stile 13, a brim portion 71 that is fixed to the rotating shaft 70 in coaxial manner and abuts the outer surface of the vertical stile 13 and a wedge portion 72 that is embedded in a side face of the slat 2.
Furthermore, as shown in Fig. 2(c), the slat holder 7A that holds the other end of the slat 2 is attached to the vertical stile 12 in rotatable manner and is constituted in the same way as the slat holder 7. The wedge portion 72 thereof is embedded in a side face of the slat 2.
Next, an example of the structure of the slat 2 will be explained.
The slat 2, as shown in Fig. 7 and other drawings, includes a bore portion 21 having a fixing portion 20 for fixing the wedge portion 72 of the slat holder 7 and a plate portion 22 extending from the lower portion of the bore portion 21 in a downward direction. The slat 2 is made of a metal such as aluminum by an extrusion forming process.
The main feature of the slat 2 is that it has a dimension such that when the slat 2 is rotated to a substantially horizontal position substantially, the upper portion thereof does not interfere with light shielding members 120 and 130 of the vertical stiles 12 and 13 (see Fig. 2 (C)). In addition, a silencer member 23 is attached to the upper outside of the bore portion 21.
When the vertical stiles 12 and 13 are provided with the slats 2 that can be opened and closed, small gaps are formed at both ends of the slats, causing leakage of light from the outside or from the inside.
This is not desirable in terms of crime prevention, so the vertical stiles 12 and 13 are provided with the light shielding members 120 and 130. In order to prevent the light shielding members 120 and 130 from interfering with the upper portion of the slat, as shown in Fig. 2 and other drawings, the slat 2 is formed so that the length of the bore portion 21 is shorter than a distance between the rotation center of the slat 2 (one end 60 of the second transmission member 6) and the light shielding member.
The silencer member 23 is made of a polyvinyl chloride, for example. The silencer member 23 mutes sounds that are generated when the upper and the lower slats abut each other upon the closing of the slats 2. The silencer member 23 also has a function of noise prevention against rain.
Furthermore, the lower stile 11 is provided with rollers 9 as shown in Fig. 2(b) so that it can be stored in a door case or is drawn out of the door case by placing it on a rail that is arranged at an opening portion
Next, an example of usage of the rain shutter door that is constituted as explained above will be explained with reference to Figs. 9(a)-9(d).
Figs. 9(a) and 9(b) are cross sections of a main portion in the closed state of the slats 2. Fig. 9(c) is a cross section of a main portion in the state where the slats 2 are opened at approximately 45 degrees. Fig. 9(d) is a cross section of a main portion in the state where the slats 2 are opened at approximately 90 degrees.
When the slats 2 are closed as shown in Figs. 9(a) and 9(b), the operating slider 15 is at the right end position as illustrated.
When the operating slider 15 is moved to slide from this position to the left side in the drawing, the sliding force is transmitted via the twisted bar 3, the rotating shaft 32, the first transmission member 5, the bar member 4, the second transmission member 6 and the slat holder 7 to the slat 2. As a result, each of the slats 2 is released at an angle that corresponds to the sliding distance of the operating slider 15.
When the operating slider 15 is moved to the center position as shown in Fig. 9(c), the slats 2 are half opened. When the operating slider 15 is further moved to the left end as shown in Fig. 9(d), the slats 2 are fully opened.
In order to close the slats 2, the operating slider 15 is moved to slide to the right side.
According to the rain shutter door 1 as explained above, firstly, the operating slider 15 is moved to slide in the horizontal direction to open or close the slats 2. Therefore, the opening and closing operation is very easy. The closed state of the slats 2 can provide a windbreak, rainproof, winterization and soundproof environment. In addition, by adjusting the opening and closing angle of the slats 2, protection of privacy, ventilation, lighting and thermal insulation can be achieved. In particular, when the slats 2 are opened at approximately 45 degrees as shown in Fig. 9(c), thermal insulation, airflow and lighting can be realized at the same time. When the slats 2 are opened at approximately 90 degrees as shown in Fig. 9(d), lighting property is improved.
Secondly, by reducing the twisted angle of the twisted bar 3, sliding can be achieved with a small force and the slats 2 can be fixed at any desired angle within approximately 90 degrees. In this case, if it is desired to increase the opening and closing angle of the slats 2, the twisted bar may be replaced with another one having a larger twisted angle.
Thirdly, since the twisted bar 3 has a twisted angle, the operating slider 15 is hardly moved to slide even if the slats 2 are moved. This structure is good in terms of crime prevention, and a production cost of the twisted bar 3 can be reduced.
Fourthly, if the twisted bar 3 is formed by reversing its twisting direction (i.e., twisted in the counterclockwise direction), the slats 2 can be opened when the operating slider 15 is at the position as shown in Figs. 9(a) and 9(b).
Fifthly, since right and left vertical stiles 12 and 13 are provided with the light shielding members 120 and 130, the structure is superior in terms of crime prevention.
Furthermore, when adopting the same structure as other rain shutter doors and other opening covering devices of the present invention, the effect thereof can be added.

Swinging mechanism of another example

Next, with reference to Fig. 10, another embodiment concerning another example of the swinging mechanism will be explained.
This embodiment has a feature that the knob portion 150 of the operating slider 15A of the swinging mechanism is attached to the upper surface of the slider body 151 and is arranged so as to be parallel with the direction X within a frame plane of the rain shutter door 1 and others. In addition, it is desirable that the slider body 151 be provided with a twisted slot 152 that corresponds to "twist" of the twisted bar 3, and the twisted bar 3 is inserted in the slot 152.
If the swinging mechanism having the above-explained structure is attached to the central stile 14, the upper stile 10, the lower stile 11, the left vertical stile 12 or the right vertical stile 13, the knob portion 150 does not protrude from the width of each stile. Thus, the size of the rain shutter door can be thoroughly made compact.
Other structures are the same as the above-explained embodiment and can have the same action and the same effect.

Swinging mechanism of another example

Next, with reference to Figs. 11-13, another embodiment concerning another example of the swinging mechanism will be explained.
This embodiment has a feature that the operating slider 15 of the swinging mechanism is provided with "rattle prevention means" to constitute an operating slider 15B.
The slider body 151 of the operating slider 15B includes a main body portion 151a, a cap portion 151b and a crimp portion 151c for crimping the main body portion 151a and the cap portion 151b.
After setting the twisted bar 3 in the twisted slot 152 that is formed in both the main body portion 151a and in cap portion 151b, they are fixed by using the crimp portion 151c.
Furthermore, the knob portion 150 is fixed to the crimp portion 151c.
The reason why the "rattle prevention means" is provided to the operating slider 15B and a structural example will be explained below.
If the twisted slot 152 is formed faithfully along the "twist" of the twisted bar 3, "rattle" is generated when operating the operating slider 15. Also, it is difficult to form the identical "twist" to all the twisted bar 3.
Therefore, a clearance needs to be provided in the twisted slot 152 for the twisted bar 3. In this case, the "rattle prevention means" adjust the clearance so that a comfortable slide operation can be realized.
The "rattle prevention means" has a structure in which a spring 151e and a ball 151f are inserted into each of two holes 151d and 151d of the main body portion 151a.
The action of the "rattle prevention means" will be explained with reference to Fig. 13. The spring 151e urges the ball 151f toward the cap portion 151b, and the ball abuts the twisted bar 3 and rotates when the operating slider 15B slides.
As a result, the clearance C that is provided in the twisted slot 152 and affects the twisted bar 3 inserted therein is adjusted appropriately, so that the slider body 151 can be moved to slide without causing a "rattle".
Furthermore, in this swinging mechanism of another example, the slat 2 has a different structure from the above-explained slat 2.
A main feature of the slat 2 is that as shown in Figs. 11 and 30 and other drawings, the position of rotating shaft 70 of the slat holder 7 is made substantially the same as the barycenter of the slat 2 by devising the shapes thereof.
If the barycenter of the slat 2 is shifted to the side of the plate portion 22, rotation of the slat 2 becomes heavy and the comfortable operability can be deteriorated.
Therefore, a part of the bore portion 21 of the slat 2, i.e., the portion at the light shielding member side from the rotation center is made thick with a little slant, so that the barycenter thereof is not shifted to the side of the plate portion 22. As a result, the position of the rotating shaft 70 of the slat holder 7 is made substantially the same as the barycenter of the slat 2 and the operability is improved.
Other structures are the same as the above-explained slat 2 and can have the same function.

Rain shutter door 1A

A rain shutter door 1A shown in Fig. 14 is different from the rain shutter door 1 in that the swinging mechanism is arranged at the right side when viewed from the inside.
By combining the rain shutter door 1 with this rain shutter door 1A, a rain shutter door that has a good usability meeting a request of a user can be provided. For example, when using two rain shutter doors, the rain shutter door 1 and the rain shutter door 1A may be used, allowing the operating sliders 15 and 15 are to be adjacent to each other. In addition, the operating slider 15 of one of the rain shutter doors can be attached to the vertical stile 13 side, while the operating slider 15 of the other rain shutter door can be attached to the vertical stile 12 side, so that a rain shutter door having a good usability can be provided.
Other structures are the same as the rain shutter door 1, the other rain shutter doors or the other opening covering devices of the present invention, so that the same action and effect can be obtained.

Rain shutter door 1B

Next, with reference to Fig. 15, an embodiment of a rain shutter door 1B will be explained.
This rain shutter door 1B is different from the rain shutter door 1 in that the swinging mechanism is divided into the upper portion and the lower portion, i.e., a first swinging mechanism for making the slats 2 between the upper stile 10 and the central stile 14 swing and a second swinging mechanism for making the slats 2 between the lower stile 11 and the central stile 14 swing.
According to this rain shutter door 1B, the upper and the lower swinging mechanisms can be operated at the same time in accordance with the installation environment. Otherwise, the upper and the lower swinging mechanisms can be operated individually.

In each of the above-explained embodiments, the operating slider 15, the twisted bar 3, the rotating shaft 32 and the first transmission member 5 are attached to the central stile 14, the left vertical stile 12 and the right vertical stile 13. However, as shown in Fig. 18, it is possible to constitute the rain shutter door stile with the upper and the lower stiles 10 and 11 and the left and right stiles 12 and 13, and by attaching the operating slider 15 to the bar portion that is attached to the upper portion of the lower stile 11 so as to make the rain shutter door 1E as shown in Fig. 18.
Furthermore, as shown in Figs. 19-21, corresponding to a position and a size of the window to which the rain shutter door is to be fixed, bar portions 14F-14H are provided to the upper portion of the lower stile 11, and the operating slider 15 is provided thereto so as to make the rain shutter doors 1F-1H, respectively.
Other structures are the same as those of the other rain shutter doors of the present invention or the other opening covering devices, so that the same action and effect can be obtained.

Rain shutter doors 1I-1K

In addition, considering an installation place and the like of the rain shutter door, the operating slider 15 and the corresponding swinging mechanism may be provided to the bar portion 14C that is under the upper stile 10 so as to make the rain shutter door 1I. Other structures are the same as the above-explained rain shutter doors, so that the same action and effect can be obtained. Furthermore, it is possible to obtain a rain shutter door 1J or 1K having a size corresponding to a size of the window portion.
Other structures are substantially the same as those of the above-explained rain shutter doors, the other rain shutter doors of the present invention or the other opening covering devices, so that the same action and effect can be obtained.
Furthermore, it is possible to insert a member for converting the rotation direction of the rotating shaft 32 into a perpendicular direction between the rotating shaft 32 and the first transmission member 5, so that the operating slider 15, the twisted bar 3 and the rotating shaft 32 are arranged on the vertical stile side.
In addition, the slats are arranged in almost the entire area within the rain shutter door stile in each of the above-explained embodiments. However, it is possible to limit them within a predetermined area such as an upper portion, a middle portion or a lower portion within the rain shutter door stile and to provide a swinging mechanism for swinging the slats.

Rain shutter door 1L having key device

It is possible to provide the lower stile 11 of each rain shutter door described above with a key device 8 and to constitute a key lever 80 removable from a lock body 81 upon locking.
For example, the key device 8 that is attached to the lower stile 11 of the rain shutter door 1L shown in Fig. 25 (see Figs. 26(a) and 26(b)) includes the key lever 80 and the lock body 81 as shown in Fig. 27 that is an exploded perspective view. The lock body 81 includes a pivoting member 82 that houses the key lever 80 and is made to pivot by the upward and downward movements of the lever 80 and a key rod 84 to which a pin 840 is fixed that is engaged with a cam groove 83 of the pivoting member 82.
The key lever 80 is provided with a protrusion 800, while a key hole 810 to which the key lever 80 is inserted has a notch 811 through which the protrusion 800 can pass, so that an insertion error of the key lever 80 is prevented.
An example of operation of the key device 8 will be explained with reference to Figs. 28 and 29. Fig. 28 is an explanatory diagram of unlock operation, and Fig. 29 is an explanatory diagram of lock operation.
As shown in Fig. 28, the key lever 80 is housed in a gap space defined by a rotating shaft 822 and shafts 823, which constitute a rotating main body 820 and a cover 821 of the pivoting member 82 in the unlocked state.
In addition, an engaging groove 801 of the key lever 80 engages the key hole 810 of the lock body 81, which cannot be removed from the key hole 810.
When the key rod 84 itself is pushed down or the key lever 80 is rotated in the clockwise direction in the drawing from the above-mentioned state, the pivoting member 82 rotates about the rotating shaft 822 so that the cam groove 83 pushes down the pin 840 of the key rod 84.
As a result, the rod 84 goes down along halls 811, 812 that are formed in the lock body 81 and enters a hole (not shown) of the rain shutter door frame 16.
When the key lever 80 erects substantially, the pin 840 enters an end of the hook of the cam groove 83, and an end 830 of the rotating main body 83 abuts an end of a flat spring 87 against a force of the flat spring 87 so that the lock operation is completed.
On this occasion, the engaging groove 801 of the key lever 80 is released from the key hole 810 of the lock body 81, so that the key lever 80 can be pulled out from the lock body 81.
Thus, unlock from the outside is difficult when the key lever 80 is stored in another place, so that crime prevention property is enhanced.
For example, the key lever 80 that is pulled out may be hung on a hook that is fixed to an arbitrary place.
According to this key device 8, the key lever can be removed from the lock body when it is locked. Therefore, the key device cannot be manipulated from the outside, so that the improvement in terms of crime prevention is achieved.

Rain shutter door 1L having prevention member

The rain shutter door 1L has a prevention member for preventing manipulation of the operating slider 15 from the outside.
An example of structure of the prevention member will be explained with reference to Fig. 30.
This prevention member is made of a slat that is not connected to the second transmission member 6 and is not rotated among the slats 2.
More specifically, the slat 2A located directly on the central stile 14 is used for preventing the rotation force of the bar member 4 from being transmitted, and an end of the plate portion 22 of the slat 2A is fixed to the central stile 14 via a restricting member 24.
According to the slats 2A, the operating slider 150 is hidden from the outside and is hardly manipulated from the outside.
As shown in Fig. 26(b), the lower stile 11 has height with wide width, and the wide portion 11A makes the key device 8 hard to touch so as to work as the prevention member.

Rain shutter door 1L having upper stile that has adjustable height and width

The rain shutter door 1L has a frame that can support different specifications of the rain shutter door frame 16 when installing the rain shutter door 1 to the rain shutter door frame 16.
Namely, the upper stile 10 includes a stile body 100 and a crown member 101 as shown in Fig. 31.
The stile body 100 is formed in a U-shape having open upper side and has an inner wall with a serrate portion 100a, while the crown member 101 is formed in a U-shape having open lower side and has an outer wall with a serrate portion 101b that corresponds to the serrate portion 100a.
Each of the serrate portions 100a and 101b has a cross section having substantially triangular crests and troughs. The serrate portions 100a and 101b meet each other and are fastened to each other by a screw B or others after adjusting the height.
The height of the upper stile 10 can be adjusted within the range where the serrate portions 100a and 101b can engage each other, so it is easy to adjust the height of the rain shutter door 1 to meet the rain shutter door frame 16.
Particularly, when replacing an installed rain shutter door 1L with the rain shutter door 1, the adjustment can be performed on a site without a precise measurement in advance.
After fixing the height of the upper stile 10, a corner block 102 is attached to each corner as shown in Fig. 32, and the corner blocks 102 are also attached to the lower stile 11.
This corner block 102 is made of a synthetic resin, for example. It can prevent a "friction" between the rain shutter door 1 and the rain shutter door frame 16.
In addition, door stoppers 103 are also attached to corners of the upper stile 10 and the lower stile 11. If there is a gap between the corner block 102 and the door stopper 103 after the above-explained adjustment of the height of the upper stile 10, a light stopper 104 may be inserted into the gap (see Figs. 32 and 33).
The light stopper 104 can be cut by a cutter or others to have an appropriate size.
As shown in Fig. 31 or other drawings, the upper stile 10 is provided with a hole 105 for fixing a rasp prevention member. As shown in Fig. 34, the rasp prevention member 106 is attached to the hole 105.
A plurality of rasp prevention members 106 having different thickness sizes is prepared, and an appropriate combination of plural rasp prevention members 106 can prevent a "rasp" between a rail groove of the rain shutter door frame 16 and the upper stile 10.
When preparing the rasp prevention members 106, for example, which have sizes of "2" mm and "6" mm, five combinations of sizes from one "2" mm to two "6" mm can support rail grooves having different specifications.
A handling portion A14 is provided as a recess at the position illustrated in Fig. 26(a) and other positions inside of the central stile 14.

Rain shutter door 1L having rollers

The rain shutter door 1L is provided with a roller device that can support a rail structure of the rain shutter door frame 16.
The rail structure and rollers of the rain shutter door frame 16 are not standardized to a single standard. In this case, if it is necessary to check the rail structure of the rain shutter door frame 16 before attaching appropriate rollers, the installing work may be complicated.
If a roller device is attached that can support the rail structure of the rain shutter door frame 16, the rain shutter door can be installed promptly without checking the rail structure of the rain shutter door frame 16 in advance. Thus, the complicated work of the installation can be resolved.
The roller device 9, as shown in Figs. 35 and 36, includes a roller case 90, a case fixing portion 91 that fixes the roller case 90 in a rotatable manner and a fixing members 92 and 93 for fixing the roller case 90. The roller case 90 is provided with two rollers 900 and 901 having different types in a rotatable manner.
The roller case 90, as shown in Fig. 37, includes a case 902 having a U-shape that has an open lower side and remained connection portions 902a and 902 after being cut, a roller 900 (a half flat roller) and a roller 901 (a U-shape grooved roller) that are attached to the case 902 by shafts and protrude from the case 902. The connection portion 902a is provided with a fixing portion 903 for the fixing members 92 and 93. The roller case 90 having the above-explained structure is attached to the case fixing portion 91 in a rotatable manner so that one end thereof holds a U-shaped portion 910 of the case fixing portion 91 and by a shaft 905 that is inserted into the shaft hole 904.
The case fixing portion 91, as shown in Figs. 40-42, includes a case 911 having a U-shape that has an opening lower side and a U-shaped portion 910 at approximately center portion of the case 911, a recess 912 for housing the other roller 901 (a U-shaped groove roller) when using the roller 900 (a half flat roller) and a recess 913 for avoiding interference with the other roller 900 (a half flat roller) when using the roller 901(a U-shaped groove roller). Fixing holes 920 and 930 for the fixing members 92 and 93 are provided on the upper surface of the case 911, and a fixing hole 914 is formed for fixing the case 911 itself to the lower stile 11.
In the roller device 9 having the above-explained structure, as shown in Fig. 43, the roller 900 (a half flat roller) is used in the case of the rail structure of the rain shutter door frame without a rail. Therefore, the fixing member 92 is used for fixing the roller case 90 to the case fixing portion 91. On the other hand, in the case where the roller 901 (a U-shaped groove roller) is used, the roller case 90 is rotated (in the counterclockwise direction in the drawing), and the fixing member 93 is used for fixing the roller case 90 to the case fixing portion 91. Therefore, according to the rain shutter door 1C equipped with the above-mentioned roller device, an appropriate roller can be selected on a site by viewing the rail structure without checking the rail structure of the rain shutter door frame in advance, and the rain shutter door can be installed promptly. Thus, a complicated work of installation can be resolved.
Other structures of the rain shutter door 1L are the same as those of the above-mentioned rain shutter doors, and the same action and effect can be obtained. In addition, it can be the same structure as those of other rain shutter doors of the present invention or opening covering devices.

Rain shutter door 1M equipped with a net member

The rain shutter door 1M is provided with upper and lower net members 17 and 17 that are positioned along a stile surface formed by the rain shutter door stile that is made of upper and lower stiles 10 and 11, left and right vertical stiles 12 and 13 and a central stile 14.
The net member 17 is made of a metal string or a synthetic resin string such as a string made of a polyester resin. The net member 17 is folded and is welded or glued after cores are inserted at the upper and the lower edges. The left and the right edges are cut in accordance with a width of the opening portion as being explained later.
The attachment structure of the net member 17 to the rain shutter door stile includes vertically longitudinal grooves 121 and 131 that are arranged along the inside surface of the left and the right vertical stiles 12 and 13, an attachment 18 that is fixed to the vertically longitudinal grooves 121 and 131, in which the left and the right edges of net member 17 are fixed to the inside grooves via the bar member 19.
The height of the vertically longitudinal grooves 121 and 131 are preferably a size that can prevent insects from entering from an opening O that is formed when the slats 2 are opened (see Fig. 45).
The attachment 18 is provided with a fixing member 180 at one end of a U-shaped opening 18K that corresponds to the vertically longitudinal grooves 121 and 131.
At the other end of the U-shaped opening 18K, a protrusion 181 is formed for preventing the bar member 19 from "falling out".
The bar member 19 can have any shape and length as long as it can engage the U-shaped opening 18K. If the cross section has a circular shape, it is easy to attach to or remove from the U-shaped opening 18K. In addition, if it is made of a synthetic resin having an elastic property and a hollow-body, the easiness of attaching and removing is enhanced.
A method for attaching the net member 17 will be explained with reference to Fig. 45. The right and the left edges of the net member 17 that was cut a little wider than the width of the opening O are made to contact with the U-shaped opening 18K of the attachment 18, and the bar member 19 is inserted in the U-shaped opening 18K. After that, the left and the right edges of the net member 17 are trimmed by a cutter or other tools.
According to the above-mentioned attaching method, the upper net member 17 covers from the lower edge of the upper stile 10 to a lateral member 20A of the slat 2A that will be explained later (see Fig. 46) and from a side edge of the left stile 12 to a side edge of the right stile 13. On the other hand, the lower net member 17 covers from the lower edge of the central stile 14 to the upper edge of the lower stile 11 and from a side edge of the left stile 12 to a side edge of the right stile 13.
This net member 17 can be removed by removing the bar member 19 from the U-shaped opening 18K. Thus, only net member 17 can be cleaned or removed in seasons when insects do not appear.
Alternatively, the net member can be a roll type.
According to the rain shutter door 1M, each of the rain shutter door can be provided with a function of preventing insects. Furthermore, if an opening covering device such as a folding rain shutter door, a lattice window, a louver or a sliding door that will be explained later can be provided with a function of preventing insects in the same way by attaching the net member 17.
Other structures of the rain shutter door 1M are the same as those of the above-mentioned rain shutter doors, so that the same action and effect can be obtained. In addition, it can be the same structure as those of other rain shutter doors of the present invention or other opening covering devices.

Folding rain shutter doors 1N-1Q

Next, an example of a structure of a folding rain shutter door 1N will be explained, in which at least two rain shutter door are folded in the outside direction.
As shown in Figs. 47-49, the folding rain shutter door 1N includes a fixed frame K1 that is fixed substantially along an opening K of a building and a first through a fourth rain shutter doors 1A'-1D' that are arranged in this fixed frame K1. The first and the second rain shutter doors 1A' and 1B' and the third and the fourth rain shutter doors 1C' and 1D' are folded in the outside direction.
The fixed frame K1 is for attaching the folding rain shutter door with a clearance between each of the rain shutter doors 1A'-1D' and the opening K and is used for adjusting positions of a sash frame and the folding rain shutter door. Particularly, it is useful when attaching a folding rain shutter door to an opening of a frame that is already installed.
The fixed frame K1 is provided with a rail portion N100 at the side frame N101 in the outside of the frame body N100. As shown in Fig. 50, both ends (L1, L2, R1 and R2) of upper and lower rail portions N102 are provided with turntables N103.
The rail portion N102 and the turntable N103 are parts on which a rod of the guide protrusion and stopper 13b of the second and the third rain shutter doors 1B', 1C' (that will be explained later, see Fig. 52) runs when the first and the second rain shutter doors 1A' and 1B' and the third and the fourth rain shutter doors 1C' and 1D' are folded or unfolded.
The fixed frame K1 is constituted as explained above and is fixed to a base frame side by the fixing member along the rim of the opening K.
The first rain shutter door 1A' and the fourth rain shutter door 1D' are substantially the same, while the second rain shutter door 1B' and the third rain shutter door 1C' are substantially the same. Therefore, an example of a structure of the fourth rain shutter door 1D' will be explained by the first rain shutter door 1A', while an example of a structure of the third rain shutter door 1C' will be explained by the second rain shutter door 1B'.
The first rain shutter door 1A' has a rain shutter door stile including an upper stile 10, a lower stile 11, vertical stiles 12 and 13 and a central stile 14. A plurality of slats 2A' and 2B' are arranged in the horizontal direction between the upper stile 10 and the central stile 14 as well as between the lower stile 11 and the central stile 14.
Rotating shafts 12a (pivot shafts) shown in Figs. 51(b) and 51(c) are attached to the upper and the lower ends 12U and 12D of the vertical stile 12 shown in Fig. 51(a) and are axially supported by bearing portions 103a (Fig. 50) provided to the turntable N103. Thus, the first rain shutter door 1A' is attached to the fixed frame K1 in a rotatable manner.
The other vertical stile 13 is provided with a hinge attachment frame N130 for hinge connection with the second rain shutter door 1B'. Furthermore, stoppers 13a shown in Figs. 51(d) and 51(e) are attached to upper and lower end portions 13U and 13D of the vertical stile 13 shown in Fig. 51(a), so that "rattle" of the rain shutter door when closing the folding rain shutter door is prevented and crime prevention property is enhanced.
The central stile 14 is formed in upper and lower rows as shown in Fig. 49, and upper and lower central stiles 14A and 14B are provided with operating sliders 15 for operating the first and the second swinging mechanisms for swinging the slats 2A' and 2B'.
The central stile 14 can be one unit instead of two row structure of the upper and the lower central stiles 14A and 14B.
When keeping the opening K of the building, the stopper 13a is released and the first rain shutter door 1A' and the second rain shutter door 1B' as well as the third rain shutter door 1C' and the fourth rain shutter door 1D' are pushed to the outside (see Fig. 53 (b)). If there is spaces at both sides of the building opening K, it can be extended as shown in Fig. 53 (c) .
In this case, rattling can be prevented by the stopper 13a provided to the second and the third rain shutter doors 1B' and 1C'. In addition, a holder H can be attached to the position shown in Fig. 53(c).
Though the above-mentioned folding rain shutter door is of a terrace type, it can be a window type folding rain shutter door 10 as shown in Fig. 54.
Furthermore, as shown in Fig. 55, a set of the first and the second rain shutter doors 1A' and 1B' and the fourth rain shutter door 1D' can be combined to be a folding rain shutter door 1P.
Furthermore, as shown in Fig. 56, the first and the second rain shutter doors 1A' and 1B' can be combined to make a set.
According to each of the above-mentioned folding rain shutter doors, an opening of a building can be closed, so that protection of privacy can be secured. In addition, it is good for windbreak, rainproof, soundproof and crime prevention properties. Furthermore, by adjusting a swing angle of the slats, sunlight can be shielded for thermal insulation. At the same time, lighting and airflow can be realized. In addition, since it is operated by sliding the operating slider 15 in the horizontal direction, easiness of the swing operation of the slats is improved so that comfortable operation of the slats can be realized.
In addition, the swinging mechanism that is easy to operate can be employed in accordance with a size and position of the opening of the building.
In addition, it can be installed in a newly-built building or can be attached to an opening of a building that is already built via the fixed frame. Other structures are substantially the same as those of the above-explained embodiment, so that the same action and effect can be obtained. In addition, it can be the same structure as those of other rain shutter doors of the present invention or other opening covering devices. In addition, a supporting device can be used, which will be explained later.

Double sliding rain shutter door 1R

The double sliding rain shutter door 1R has at least two rain shutter doors attached to the rain shutter door frame that is formed at an opening of a building, and at least one set of plural slats are arranged in the rain shutter door stile of each rain shutter door in openable and closable manner. The rain shutter doors are attached to the rain shutter door frame so that they can slide to each other with the slats of the rain shutter door being opened.
The double sliding rain shutter door 1R is constituted so that one set of plural slats 2 are arranged in openable and closable manner in the rain shutter door frame B that is attached to the opening portion A of the building afterward and that the inside and the outside rain shutter doors 1 and 8A can slide even in the state where slats 2 are opened.
Therefore, the inside and the outside rain shutter doors 1 and 8A can be positioned so as to overlap each other in the state where the slats 2 of the outside rain shutter door 8A are fully opened and the slats 2 of the inside rain shutter door 1 are fully opened. Accordingly, it is not necessary to secure a space for housing the rain shutter doors 1 and 8A in a door case or others, while lighting property of the opening portion A can be secured. In addition, when the inside and the outside rain shutter doors 1 and 8A close the opening portion A, and when the slats 2 are opened for securing lighting property, outside thermal insulation is realized and protection of privacy can be realized. Furthermore, even in the sate where the inside and the outside rain shutter doors 1 and 8A close the opening portion A and the slats 2 of the inside and the outside rain shutter doors 1 and 8A are opened, the opening portion A can be opened by pulling one of the inside and the outside rain shutter doors 1 and 8A, so that there is no problem in an emergency escape from a fire or others.
The rain shutter door frame B includes the left and the right vertical stiles B1 and B2 and the upper and the lower horizontal stiles B3 and B4 that define an opening frame B5. A movable area B6 where the inside rain shutter door 1 can move and a movable area B7 where the outside rain shutter door 8 can move are disposed in the opening frame B5. Between the areas B6 and B7, there is provided a sliding area B8 where the inside and the outside rain shutter doors 1 and 8A can be slided even in the sate where the slats 2 of the inside rain shutter door 1 are opened fully.
The upper stile B3 above each of the movable areas B6 and B7 is provided with a U-shaped portion B30 having an opening lower side, while the lower stile B4 under each of the movable areas B6 and B7 is provided with a rail portion B80, so that the inside and the outside rain shutter doors 1 and 8A can run.
In addition, an insect protecting stile B81 is attached to the upper stile B3 for preventing insects from entering in cooperation with a insect protecting fin 123 of the inside rain shutter door 1 that will be explained later. On the other hand, the lower stile B4 is provided with a mountain portion B82 between the rail portions B80.
The width W of the sliding area B8 can be a size substantially the same as the maximum width W1 when the slats 2 of the inside rain shutter door 1 are opened or plus a little clearance. Therefore, if the rain shutter door stile of the inside rain shutter door 1 is formed so as to house the width W2 when the slats 2 of the inside rain shutter door 1 are opened, the sliding area B8 is not necessary.
The reference symbol "B9" denotes a mohair, and the reference symbol "B10" denotes a glass-fitted sliding door.
In this embodiment the opening covering device is attached to the outside of two glass-fitted sliding doors. However, it is possible to attach the opening covering device to the outside of a double sash including four glass-fitted sliding doors.
Next, an example of a structure of the inside rain shutter door 1 will be explained with reference to Figs. 58 and 59.
This inside rain shutter door 1 has a rain shutter door stile including the upper stile 10, the lower stile 11 and the left and the right vertical stiles 12 and 13. Along the stile surface, plural slats 2 are arranged in the horizontal direction, and the operating slider 15 for operating the swinging mechanism is disposed at the bar portion 14 that is arranged above the lower stile 11. Further, a net member 17 is disposed for covering the stile surface. When the operating slider 15 is moved to slide in the horizontal direction in Fig. 59, each of the slats 2, 2, 2, ... swings to open or close.
The upper stile 10 is attached to the upper frame B3 along the U-shaped portion B30 having an opening lower side so as to be able to slide, while the lower stile 11 is provided with rollers 110 so as to run on the rail portion B80.
Cushion members 120A and 130A are attached to a portion where the vertical stiles 12 and 13 abut the vertical frames B1 and B2 of the rain shutter door frame B, and a part of the swinging mechanism is housed in the bore portions 121 and 131 of the vertical stiles 12 and 13.
Furthermore, as shown in Fig. 59, the light shielding members 120 and 130 are formed at the inside portions of the vertical stiles 12 and 13. The reason for this is as follows. If swinging openable and closable slats 2 are attached to the left and the right vertical stiles 12 and 13, small gaps are formed at both ends of the slats that may leak light from the inside or from the outside. The light shielding members 120 and 130 are provided for preventing this leakage of light.
The vertical stile 12 is provided with the insect protecting fin 123 that has a vertical length equal to the length between the position of contact with the insect protecting frame B81 of the rain shutter door frame B and the position of contact with the mountain portion B82 of the rain shutter door frame B, and a horizontal length substantially identical to a width W of the sliding area B8.
Reference numerals "124" and "134" denote handling portions that are provided to the vertical stiles 12 and 13.
The bar portion 14 is for housing a part of the swinging mechanism. As explained above, the operating slider 15 is disposed at the inside, and the upper portion is provided with the fixing member 140 for fixing the net member 17.
Next, a rain shutter door lock 9A for locking the inside and the outside rain shutter doors 1 and 8A will be explained.
The rain shutter door lock 9A, as shown in Fig. 60, includes a crescent fin 9A that is formed at the insect protecting fin 123 of the inside rain shutter door 1 and a crescent body 91A attached to the crescent fin 9A in a rotatable manner. A crescent receptacle 92A is fixed to the inside portion of the vertical stile 13 of the outside rain shutter door 8A. When a handle 910A of the crescent body 91A is tilted in the inside direction, it becomes "open", while it becomes "close" when the handle 910A is tilted in the outside direction.
The rain shutter door frame B equipped with the rain shutter doors 1 and 8A having the above-explained structure, as shown in Figs. 57 and 58, is fixed to a sash frame C by fastening means such as bolts and nuts after sandwiching a screen door frame or an equivalent of the sash frame C as the opening portion with a fixing fin B11 of the left and the right vertical frames B1 and B2 and the upper and the lower horizontal frames B3 and B4 and a fixing member B12 that is formed of a different member from the rain shutter door frame B. In addition, the backside of the mountain portion B82 of the lower frame B4 is supported by a support device C1 that is placed on the sash frame C.
Therefore, the sash frame C of the building base frame side is not damaged when fixing the rain shutter door frame B to the sash frame C afterward.
Next, an example of usage of the rain shutter doors 1 and 8A having the above-mentioned structure will be explained with reference to Fig. 61.
As shown in Fig. 61, when the operating slider 15 is moved to slide so that the slats 2 are opened fully, amount of lighting in the case of arranging the inside and the outside rain shutter doors 1 and 8A overlapping each other is approximately 70-80% of that without the rain shutter door. In addition, since the inside and the outside rain shutter doors 1 and 8A can be arranged to overlap each other, a half of the opening portion A can be released so that sufficient lighting property can be secured.
Furthermore, in order to close the slats 2, the operating slider 15 is moved to slide in the right direction.
According to the above-mentioned rain shutter door, firstly, amount of lighting is secured. Therefore, the inside and the outside rain shutter doors 1 and 8A can be kept in the opening portion A, and a door case or an equivalent is not necessary. It is not required to consider a space for the same.
Secondly, even in the state where the slats 2 of the inside rain shutter door 1 are fully opened, the inside and the outside rain shutter doors 1 and 8A can be arranged to overlap each other. Therefore, the opening portion A can be released regardless of the opening and closing states of the slats 2, so there is no problem when a person enters or goes out or when an emergency happens.
Thirdly, if the inside and the outside rain shutter doors 1 and 8A are installed in the opening portion A at a high level floors of a high-rise condominium or the like, a feeling of high elevation that a resident may feel through a window can be relieved.
Fourthly, since the slats 2 are opened or closed by sliding the operating slider 15 in the horizontal direction, the opening and closing operation is very easy. When the slats 2 are closed, windbreak, rainproof, protection against the cold and soundproof can be realized. In addition, by adjusting the angle of opening and closing, outside thermal insulation is realized, and privacy can be protected. Particularly, when the slats 2 are opened at approximately 45 degrees, thermal insulation, airflow and lighting can be realized simultaneously.
Fifthly, the net member 17 that is attached to the rain shutter door stile can prevent insects from entering the inside through the opening O.
Sixthly, when the net member 17 is structured to be detachable, the net member can be cleaned, replaced or removed and can be stored during winter when insects do not appear.
Next, an embodiment of an attachment structure of the double sliding rain shutter door 1R will be explained with reference to Fig. 62.
As explained above, the double sliding rain shutter door 1R is fixed to a sash frame C by fastening bolts and nuts or equivalents after sandwiching a screen door frame or an equivalent of the sash frame C from which the screen door is removed (not shown) with a fixing fin B11 and the fixing member B12 of the rain shutter door frame B. However, it is possible to fasten the fixing member B12 with the screen door frame and the rain shutter door frame B of the sash frame C by bolts and nuts or equivalents.
In this embodiment, installation work becomes simpler. The other structure is the same as the above-mentioned embodiment, so the same actions and effects can be obtained.
Next, an embodiment of another attachment structure will be explained.
Features of this attachment structure, as shown in Figs. 63 and 64, include that the rain shutter door frame B is fixed to the base frame side not by an opening portion like the sash frame C but by a fixing member B13, and that each of the inside and the outside rain shutter doors 1 and 8A is provided with an central stile 14A and the slats 2 are arranged at the upper and the lower portions so as to be operated by a first and a second swinging mechanisms that are constituted similarly to the above-mentioned swinging mechanism. The other structure is the same as the above-mentioned embodiment, so the same actions and effects can be obtained.
Next, an embodiment of another attachment structure will be explained with reference to Fig. 65.
A feature of this embodiment is that the sash frame C and the rain shutter door frame B are united so as to be used for a new building. The other structure is the same as the above-mentioned embodiment, so the same actions and effects can be obtained.
It is possible to use a roll type screen door instead of the net member 17 of the rain shutter door in each of the above-mentioned embodiments. Furthermore, the double sliding rain shutter door 1R except for the above-mentioned structure can have the same structure as the other rain shutter door of the present invention, other opening covering devices, or a support device that will be explained later.

Lattice Window 1W

The lattice window 1W is an opening covering device that is fixed to a window portion of a building and includes at least one set of plural slats arranged within the frame surface and a swinging mechanism for swinging the slats.
The lattice window 1W, as shown in Figs. 66 and 67, has a frame that includes the upper stile 10, the lower stile 11 and the left and the right vertical stiles 12 and 13. A plurality of slats 2 are arranged in the horizontal direction within the frame surface, and swinging mechanisms for swinging the slats 2 are housed in the left and the right vertical stiles 12 and 13 and in the bar portion 14 above the lower stile 10.
An operating slider 15 that can slide along the upper surface of the bar portion 14 operates the swinging mechanism.
Therefore, a linear operation of sliding a knob portion of the operating slider 15 activates the swinging mechanism, so that the operation is simple and easy.
In addition, since the operating slider 15 is arranged so as to slide in the frame surface inner direction X, the operating slider 15 is housed within a width of the device 1 in the foresight direction, the lattice window 1W itself can be thin and compact.
In addition, since the operating slider 15 is housed within the width in the foresight direction, the lattice window 1W can be attached to the window without any restriction due to the position of the operating slider 15, so that a flexibility of the installation work is enhanced.
The upper stile 10, the lower stile 11, the left and the right vertical stiles 12 and 13 and the bar portion 14 can be formed by aluminum molding, for example, and assembled.
The upper surface 140W of the bar portion 14, as shown in Fig. 68, is provided with a groove 141W for a fixing member of the operating slider 15.
The device having the above-mentioned structure, as shown in Fig. 70, is fixed to an outside portion of a small window 9W via a bracket 8W.
In this case, since the operating slider 15 is arranged on the upper surface of the bar portion 14, the space between the lattice window 1W and the building base frame can be any desired value.
Though the knob portion 150 of the operating slider 15 is provided at the inside upper surface 1400 of the bar portion 14 in this embodiment, it can be provided at the inside surface 143.
The operating slider 15, the twisted bar 3 and the rotating shaft 32 are attached to the bar portion 14 above the lower stile 10 in the above-mentioned embodiment. However, the bar portion can be attached under the upper stile 10, so that the twisted bar 3 and others can be housed therein.
In addition, it is possible that the bar portion 14 is not provided, and instead the operating slider 15, the twisted bar 3 and the rotating shaft 32 are arranged in the lower stile 11 or in the upper stile 10.
Next, with reference to Figs. 71 and 72, an embodiment of a lattice window 2W will be explained.
The lattice window 2W of this embodiment is different from the lattice window 1W in that the slats 2 are provided continuously in the horizontal direction via a pillar 16W.
Namely, in Fig. 71, a lattice window 1W having the same structure as the above-mentioned lattice window 1W is provided at the right side.
Therefore, as shown in Fig. 73, the swing angle of the left slats and that of right slats can be different to each other.
The other structure and effects thereof are the same as the above-mentioned embodiment, so detailed explanation is omitted. Structures except for the above-mentioned structure can be the same as the other rain shutter doors of the present invention or other opening covering devices.
Though two sets of slats are provided in this embodiment, the number is not limited to two, and three or more sets can be available.
According to the present invention, when the slats are closed completely, effects of crime prevention, rainproof and windbreak are obtained. When the angle of opening and closing of the slats is made small, effects of protection of privacy and outside thermal insulation can be obtained. In addition, airflow, ventilation and lighting are possible in proportion to the opening angle of the slats.
Furthermore, since the twisted bar is used for converting a sliding force into a rotating force, the operating slider for applying the sliding force can be housed within the frame surface compactly.
In addition, the slats can be kept at a stable position of a desired angle of opening and closing, and even if the slats are urged to move in this state, the force is hardly transmitted to the operating slider.
In addition, when the twisting angle of the twisted bar is adjusted, the sliding force that is applied and the swing angle (the angle of opening and closing) of the slats can be adjusted.
In addition, since the operating slider does not protrude from the frame surface, the lattice window can be made compact. In addition, since the operating slider is arranged at a position facing an opening of a window, the lattice window can be fixed to a window portion of a building without depending on a position of the operating slider, so that a flexibility of installation work can be improved.

Sliding Door 1X

Next, as an embodiment of the present invention, an example of the structure of the sliding door 1X will be explained with reference to Fig. 74.
The inside surfaces of the left and the right vertical stiles 12D and 13D of this sliding door 1X are provided with vertically longitudinal grooves in the same way as the above-mentioned embodiments, and a net member 17 is attached to the inside groove of the attachment 18 via a bar member 19.
The other structure is the same as the rain shutter door of the above-mentioned embodiments, so the same actions and effects can be obtained. Other structures except for the above-mentioned structure can be the same as the other rain shutter doors of the present invention and other opening covering devices. Furthermore, though the inside sliding door and the outside sliding door can have the same structure, it is possible to adjust widths of the slats 2E and 2F, so that sliding operation of the sliding door is not interfered.

Metal Supports

1Y and 1Z of Opening Covering Device

The metal support 1Y, as shown in Fig. 75, has a structure in which a main body 10Y is fixed to the backside of a lower frame 20Y of an external frame 2Y as a frame, and a rotatable screw 11Y is attached to the main body 10Y through a hole 200Y that is provided to the lower frame 20Y.
According to this metal support 1Y, the screw 11Y can be rotated through the hole 200Y of the lower frame 20Y by using a driver or an equivalent, so a sag of the lower frame 20Y can be easily corrected from the inside as will be explained later.
The main body 10Y includes a threaded attachment portion 100Y with a female thread for fixing the screw 11Y and an attachment plate 101Y. At the center of the attachment plate 101Y, a through hole 102Y is provided which corresponds to the lower frame hole 200Y.
The screw 11Y is provided with a male thread 110Y that corresponds to the threaded attachment portion 100Y, the screw head 111Y is provided with a "-" or "+" groove, and the tip 112Y is formed substantially flat.
The metal support 1Y having the above-mentioned structure is fixed by making the through hole 102Y meet the lower frame hole 200Y and by fixing the attachment plate 101Y to the backside of the lower frame 20Y. The required number of the metal supports 1Y that are fixed to the backside of the lower frame depends on a size of the external frame and is usually two or three.
Though the main body 10Y is formed in a cylindrical shape, it is not limited to such a shape, and a shape of the attachment plate 101Y is not limited to a rectangular block.
Next, an example of usage of the above-mentioned metal support 1Y will be explained with reference to Fig. 77.
The metal support 1Y is attached to the external frame 2Y in advance, a pinching portion 40Y of a drive-in type brackets 4Y (see Fig. 78) is driven to each of plural positions of the screen door rail, the left and the right vertical frames and the upper frame of the sash frame 7Y, and the external frame 2Y is fixed to the brackets 4Y so as to assemble the rain shutter door 3Y.
It is desirable to lay a base plate 5 on a dish plate 21Y at a position where the tip 112Y of the metal support screw 11Y abuts. That is for dispersing a weight of the rain shutter door 3Y and others and for avoiding damage to the dish plate 21Y.
After that, sag of the external frame 2Y due to the weight of the rain shutter door 3Y and others is corrected by rotation of the screw 11Y, and height of the lower frame 20Y is adjusted so that the lower frame 20Y can keep substantially the horizontal posture.
A plurality of slats 31Y are arranged in the rain shutter door stile 30Y of the rain shutter door 3Y in openable and closable manner, and the rain shutter door 3Y can be attached to the external frame 2Y so as to be able to slide in the state where the slats 31Y are opened.
According to the metal support 1Y, firstly, sag of the external frame 2Y can be corrected easily from the inside by using a driver or an equivalent when installing the external frame 2Y. Secondly, even after installation of the external frame 2Y, the height of the external frame 2Y can be adjusted easily and precisely. Thirdly, the opening portions of the sash frame 7Y, the dish plate 21Y and others cannot be damaged.
Next, an embodiment of the metal support 1Z will be explained with reference to Figs. 79 and 80.
The metal support 1Z, as shown in Fig. 79, includes an upper hinge 60Z that is fixed to a lower frame 20z side of an external frame 2Z as the frame, a lower hinge 61Z that is fixed to the base frame side and a main body 62Z attached between the upper hinge 60Z and the lower hinge 61Z.
The main body 62Z includes shaft portions 620Z at both ends and is formed in a shape like a piece member or a longitudinal member.
The upper hinge 60Z includes a bearing portion 600Z for supporting the shaft portion 620Z of the main body 62Z and a fixed portion 601Z that is fixed to the lower frame 20Z. The bearing portion 600Z abuts the lower frame 20Z, and the notch 602Z thereof is disposed at the base frame side since the bearing portion 600Z is formed substantially perpendicular to the fixed portion 601Z. Furthermore, as the upper hinge 60Z that will be explained later with reference to Fig. 82, the bearing portion 600Z can be formed substantially perpendicular in the opposite direction to the fixed portion 601Z.
The lower hinge 61Z includes a bearing portion 610Z for supporting the other shaft portion 620Z of the main body 62Z, a fixed portion 611Z that is fixed to the base frame side and a notch 612Z that is provided to the bearing portion 610Z.
The notches 602Z and 612Z of the upper and the lower hinges 60Z and 61Z are cut off so that the main body 62Z can be rotated by approximately 50 degrees.
The upper and the lower hinges 60Z and 61Z are formed in a shape like a piece member or a longitudinal member similarly to the main body 62Z.
Each shaft portion 620Z of the main body 62Z is formed in substantially a cylindrical shape, and the bearing portions 600Z and 610Z of the upper and the lower hinges 60Z and 61Z are formed so as to engage the shaft portions 620Z. The main body 62Z and each of the upper and the lower hinges 60Z and 61Z can be formed so as to be engaged each other detachably. Therefore, in order to support different distances between the sash surface and an outside wall surface, long and short types of the main body 62Z may be prepared so that they can be exchanged to be attached to the upper and the lower hinges 60Z and 61Z in an installation site.
According to the metal support 1Z having the above-mentioned structure, a screw retainer 202Z is attached to an attaching portion 201Z that is provided to the lower frame 20Z, and the upper hinge 60Z is fixed to the screw retainer 202Z. The lower hinge 61Z is fixed to the base frame side via a hole-in anchor or an equivalent.
Next, an example of usage of the above-mentioned metal support will be explained with reference to Figs. 81 and 82.
Fig. 81 is a cross section of the opening portion in the state where the external frame 2Z is attached, in which the sash surface of the sash frame 7Z is the same level as the outside wall surface.
The upper hinge 60Z is attached to the external frame 2Z in advance so as to fix the metal support 1Z. As explained above, the brackets 4Z are driven into plural positions of the screen door rail of the sash frame 7Z, the left and the right vertical frames and the upper and lower frame so as to sandwich the external frame 2Z, which is fixed to the brackets 4Z. Thus, the lower hinge 61Z is fixed to the base frame side at the position where the external frame 2Z retains substantially the horizontal posture. After that, the rain shutter door 3Y is assembled. According to this metal support 1Z, as shown in Fig. 82, a sag of the external frame 2Z can be avoided in the case where the sash surface of the sash frame 7Z is the same level as the outside wall surface and in the case where the sash surface of the sash frame 7Z is at the inner position with respect to the outside wall surface.
Namely, according to the metal support 1Z, the lower hinge 61Z can be fixed to the base frame side in accordance with a distance between the sash surface and the outside wall surface, so that it can support the different states of the opening portion. As explained above, according to the metal support 1Z, firstly sag can be prevented when the external frame 2Z is attached to an opening portion without the dish plate 21Y. Secondly, concerning the relationship between positions of the sash surface and the outside wall surface, one type of metal support 1Z can support an "inside attachment type", a "half outside attachment type", a "outside attachment type" and other types. Furthermore, in addition to the above-mentioned structure, the same structure as other rain shutter doors of the present invention or other opening covering devices can be adopted.
