  Hereinafter, a vertical blind according to the present invention and a window structure having the same will be described.

  The vertical blind according to the present invention is a vertical blind in which adjacent slats are suspended in an independent state, and the slat is a gap that fills a gap between a long wing and an adjacent wing. A gap filling member having a buried portion, and the gap filling member is provided for each wing body so as to fill a gap between adjacent wing bodies. This independent state means that the side edges of adjacent slats are not directly connected.

  When heating indoors in the winter, even if vertical blinds are provided on the indoor window surface, if there is a gap between the wings, the cold air from the window surface passes through this gap and moves indoors. To do. Also, in summer, hot air from the window surface passes through and moves indoors.

For this reason, even if a vertical blind having wings with high thermal insulation performance is used, the thermal insulation performance cannot be sufficiently exhibited due to the gaps between the wings. By suppressing the passage of hot air, the insulation performance of the wings can be sufficiently exhibited.
<Body>
The present inventors have already formed a fiber containing polyethylene terephthalate (PET) and ethylene-vinyl alcohol (EVOH), and as a light-transmitting heat-shielding sheet excellent in light-transmitting property, heat-shielding property and heat insulating property. We have filed a patent application (Japanese Patent Application No. 2010-045563) for a fiber structure, a vertical blind body using this, and a vertical brand.

  Here, in general, as a vertical blind or a vertical curtain, there is a demand for a material having excellent daylighting performance even in a closed state in order to shield against solar radiation while having heat insulation performance. The wing of the fiber structure can be suitably used as the wing of the vertical blind. Accordingly, the wings according to the present invention include those formed using the translucent heat shield sheet of Japanese Patent Application No. 2010-045563.

  The cross-sectional shape of the wing is preferably rectangular in view of ease of processing and cost. The length of the wings can be the same length as a slat of a general vertical blind.

  The width of the wings can also be set so that the edges of the wings do not overlap when the vertical blind is closed, but the width of the wings should be set so that the edges of the wings overlap. May be. For convenience, the former is assumed to have “no overlapping wings” and the latter is “with overlapping wings”.

  In the case of “no wing overlap”, the gap between the wings is a gap G1 between the side surface of the wing body and the side surface of the wing body adjacent thereto (see FIG. 2B). In this case, a gap G2 is formed between the edge of the wing and the edge of the wing adjacent to the wing (see FIG. 18).

As will be described later, when the wings are stored by section, they can be used as smaller wings than a general one.
<Gap filling member>
Examples of fibers that can be used for the gap filling member include fibers such as mohair, polyethylene terephthalate (PET), and ethylene vinyl alcohol (EVOH). Since these fibers have translucency, they can be used particularly suitably when the wings have translucency.

  When the gap filling member is in the form of a cloth, the use of mohair can inevitably form a mohair-like cloth. If the cloth or bag is formed using this cloth, and the wings are covered and used as a slat, the lighting performance of the above-described vertical blind is hardly impaired, and the design property is not easily impaired.

  When the gap filling member is formed into a sheet shape, in the case of “no wing overlap”, it is necessary to form the sheet member in a sheet shape wider than the width of the wing body. More preferably, it is widened so that the side edge parts of an adjacent sheet | seat overlap. In this case, it is preferable to be attached to one surface of the wings along the longitudinal direction of the wings so as to fill the gaps between the wings.

  On the other hand, in the case of “with overlapping wings”, the shape of the gap filling member is not particularly limited as long as the gap between the edges of the overlapping wings can be filled in the longitudinal direction of the wings.

  When the gap filling member is formed into a bag shape, it is necessary to form it in a bag shape wider than the width of the wings regardless of “with or without wing overlap”. It is preferable that the bag is widened by adjusting the thickness and width of the bag so as to fill the gap between the wings, and is formed in a long shape.

  In particular, in the case of “no wing overlap”, the side edges of adjacent bags need to be widened so as to overlap each other.

  Further, in the case of “no wing overlap”, the wing body and the bag-like gap filling member (hereinafter simply referred to as “bag” in the embodiment for carrying out the invention) have translucency, When widening the bag by changing the thickness of the side edge of the bag, the thickness of the side edge is changed and the back surface of the side edge of the changed thickness is brought into surface contact with the side edge of the wing body. By adjusting the density, it is possible to adjust the entire wings of the vertical blind to uniform translucency, and to prevent uneven transmission when the sunlight is inserted into the room. For example, this part can also be achieved by folding the cloth a plurality of times to form a folded portion.

  Regardless of whether or not there are overlapping wings, the lower and upper edges of the bag are extended so that they extend toward the floor or ceiling rather than the vertical slats of vertical blinds. May be. This extension can further suppress hot air movement in summer and cold draft in winter.

  Furthermore, a core material that enhances the shape retention of the bag may be provided along the side edge portion of the bag regardless of “with / without wing overlap”. This core material is harder than the material of the bag and has a long shape, and preferably has translucency. For example, a light-transmitting rod-like resin harder than the bag can be used.

  With this core material, the shape retention of the bag is enhanced and a gap is not easily formed between the slats. The width, length, shape, etc. of the core material can be appropriately changed according to the gap between the wings and the shape of the wings. The gap between the wings can be filled with this core material.

  In addition, regardless of “with / without wing overlap”, the bag can be provided with a weight at the lower edge portion of the bag, and the bag containing the wings can be pulled downward to improve the shape retention of the bag. In this case, weights may be provided at both ends of the lower edge of the bag in a balanced manner, or may be provided along the lower edge of the bag as weights close to the length of the lower edge of the bag. Thereby, the bag can be pulled with the width of the bag, and the shape retention of the bag can be improved.

  Further, regardless of “with or without wing overlap”, ribs may be provided on the front surface or the back surface of the bag in a direction crossing the longitudinal direction of the bag to enhance the shape retention of the bag. There may be a plurality of ribs, and the formation position and shape of the ribs may be any as long as they do not cause a gap between the wings. This rib is more preferably one that does not impair the design. In the case of “with wing overlap”, the outer ribs can fill the gaps between the edges of the wings.

  Regardless of whether the wings are overlapped or not, the wings are cut at any height without changing the length of the slats to form two or more cut pieces. In addition, the inside of the bag may be partitioned by partitioning portions, and the cut pieces of the wings may be stored in the respective partitions.

  This partitioning can be performed, for example, by bonding inner surfaces facing each other inside the bag or forming ribs on the inner surface, so that the shape retention of the bag is enhanced.

  The storage of the wings in this section may be performed by forming an entrance for storing the wings in the substantially closed internal space.

  When the inside of the bag is partitioned, opening / closing means such as a hook-and-loop fastener may be provided at the entrance of each compartment for storing the wings or at the opening of the bag so that the opening of each entrance or bag can be opened and closed. In addition to easily storing the wings in the above-described sections, the opening / closing means functions like a rib, so that the shape retention of the bag can be improved.

Also, when the inner space of the compartment is made slightly larger than the volume of the wings housed here, the opening / closing means is closed in the bag provided with the opening / closing means compared to the bag not provided with the opening / closing means at the entrance of the compartment. Since the wings are sometimes stored more closely in the bag, the shape retention of the bag can also be improved.
<Window structure>
In winter, a cold draft occurs in which cold air falls from the window to the indoor side and moves on the floor, so even if a vertical blind with high thermal insulation is attached to the window, the vertical blind is placed between the window blind and the wall or floor. If there is a gap, the room gets cold. Similarly in the summer, hot air from the window surface passes through the gap and the room gets hot.

  For this reason, the window-side structure according to the present invention has the vertical blind provided on the indoor side of the window of the building, and fills the space between the vertical blind and at least one of the indoor wall and floor. A window edge member is provided. The gap between the vertical blind and the window frame may be filled.

  This window edge member is provided between the vertical blind and at least one of the indoor wall or floor (or window frame) so that cool air and hot air accumulated in the space between the vertical blind and the window surface do not flow into the room. It is what The window surface is covered like a door pocket by the window edge member and the vertical blind, and cold air and hot air can be substantially confined in the door pocket.

  In both winter and summer, when the blinds are closed, there is a tendency that cold air and hot air stay between the vertical blinds and the window surface, and the room may become too dark.

  Therefore, it is preferable that the window edge member is translucent and has heat insulation properties from the viewpoint of indoor lighting and from the viewpoint of heat insulation between the interior of the door pocket and other indoor spaces. A resin plate, a mohair-like cloth, or the like manufactured from a resin such as the above-described translucent heat shield sheet can be preferably used.

  In the case of using a plate member such as a resin plate as a window edge member, for example, it has two or more plate surfaces that are substantially orthogonal, one plate surface of which is parallel to the window surface, and the other The plate surface is fixed to at least one of the floor or wall in the room so as to be substantially orthogonal to the window surface, and the parallel plate surface overlaps a part of the indoor side surface of the wing body. In particular, by making the vertical blind slats contact the window edge member from the outside of the room, it is difficult for the window edge member to be deformed or misaligned from the installation location due to the negative pressure due to the movement of the person or the opening and closing of the door. In addition, if the window edge member overlaps the wings from the indoor side, even if the door is opened and closed, the wings sway back and forth, and a gap is not easily generated between the wings.

  In addition, when a mohair cloth is used as a window edge member, it is inevitably a mohair-like cloth, and it is more preferable that the indoor lighting and the design at the window due to the provision of the window edge member are not impaired.

  Attach the mohair-like cloth to the support member provided on the wall of the bottom of the slat, the bag, the upper part of the window, etc. so that the gap between the slat and the floor surface is filled with the slat suspended. Also good. By doing in this way, the cold air that has come down from the window surface becomes difficult to move indoors through the slat, the floor surface, the wall surface, and the gap, and the design property is not easily impaired.

  When a mohair-like cloth is attached to the lower part of the slat wing or bag, for example, the surface A of the hook-and-loop fastener (the side raised on the hook) or the B surface (loop) If the A side of the hook-and-loop fastener is attached to the mohair-like cloth, the B side is attached. If the B side is attached, the A side is attached and the both sides are peeled off. It can also be attached as possible.

  Furthermore, if the window edge member fixed to the floor or wall and the slat of the vertical blind are provided with attachment / detachment means such as a magnet and a hook-and-loop fastener that can be attached / detached, the both can be attached and detached. The slats or wings are less likely to swing back and forth due to the negative pressure in the room due to the movement of people or the opening and closing of the doors, and gaps between the wings are less likely to occur. If this magnet is also used as the weight, the number of parts of the vertical blind can be reduced.

<Slats>
FIG. 2A shows a schematic view seen from the front of the vertical blind in the direction of arrow A in FIG. FIG. 2B is a cross-sectional view taken in the arrow direction of the line BB (cross section in the horizontal direction) of FIG.

  As shown in FIG. 2, the slat 22 has a wing body 2 and a lace bag 9 (a gap filling member) that stores the wing body. The lace bag 9 stores the wing body 2 and the wing body 2. Is suspended from the gripping member of the runner 3 so as to be rotatable around the axis of the shaft, and a gap G1 is provided between the suspended wings 2 and 2.

The wing body 2 is formed in a long plate shape having a rectangular cross section formed using the light-transmitting heat-shielding sheet described in Japanese Patent Application No. 2010-045563. The wing 2 is housed in a lace bag 9 shaped into a long bag that is open only at one end (the upper end in FIG. 2A).
<Translucent bag>
As shown in FIGS. 2 (A) and 2 (B), the lace bag 9 has a long translucency that is wider than the width of the wing 2 so as to fill a gap G1 between the adjacent wings 2,2. The bag. Moreover, the side edge part (gap filling part) of the race bag 9 of one slat 22 has overlapped with the side edge part of the race bag 9 of another one slat 22 adjacent to this.

Hereinafter, operations and effects of the vertical blind and the window-side structure of the first embodiment will be described.
(Vertical blind)

  On the other hand, in the vertical blind 1Pa in the case of a slat of a wing 2P having a width of 9 cm without a lace bag (see Comparative Example 1, FIG. 19), about 38 ° C. (after 4 minutes) to about 50 ° C. (1 hour) After), it changed at a slightly higher temperature.

  Therefore, the surface temperature on the indoor side of the vertical blind was lower by about 3 to 4 ° C. when the wings were housed in lace bags. In addition, it is the same conditions that the floor is not closed in both Example 15 and Comparative Example 1.

From this result, it is clear that the side where the race bag 9P is attached has a heat insulating property inside and outside the door bag-like space covering the window surface (limited to the interior) because the gap G2 (see FIG. 18) between the overlapping wings is filled. Rise.
(Effectiveness of floor covering in summer)
A slat of a wide wing 2P (see FIG. 19) with a width of 9 cm, with the floor closed to fill the gap between the vertical blind 1P and the floor 8 (Comparative Example 2) and without the floor closed (Comparative Example 1) (All are not shown, see FIG. 13). As shown in FIG. 16A, the temperature of the indoor side surface of the vertical blind 1P is about 38 ° C. for 4 minutes to 1 hour from the start of irradiation. (4 minutes later) to about 50 ° C. (after 1 hour), which is substantially the same (see FIG. 16A).

  However, at the room center temperature, as shown in FIG. 16B, when the floor is closed after 4 minutes to 1 hour from the start of irradiation (Comparative Example 2), about 30 ° C. (after 4 minutes) to about 37 ° C. On the other hand, in the case where the floor was not blocked (Comparative Example 1), the temperature increased slightly from about 32 ° C. (after 4 minutes) to about 39 ° C. (after 1 hour).

When the floor is closed (Comparative Example 2), the temperature is lower by about 2 ° C. (see FIG. 16B), and it is advantageous to close the floor even in summer.
(Effectiveness of floor clogs in winter)
In the winter irradiation test, when there is no floor covering that fills the gap between the vertical blind and the floor 8 (Comparative Example 1), a low-temperature belt (see FIG. 17A) is formed in the gap between the vertical blind and the floor 8. It can be seen that a cold draft has occurred.

On the other hand, when there is a floor clogging with the resin plate 5B (Comparative Example 2), it can be seen that the cold draft is suppressed by the resin plate 5B (see the arrow in FIG. 17B).
(Difference in heat insulation due to overlap width)
As the overlapping width W (see FIGS. 18 to 20) between the edges of the wings 2P and 2P is larger, the gap G2 between the edges becomes larger and it becomes difficult for cold air and hot air to pass through, so that the heat insulation is improved. In this case, if the gap G2 is filled with a race or the like, it will lead to an increase in the number of portions filled with the gap G2, so that the heat insulation is further improved.

  When the width of the wing without a race is 7.5 cm (see Comparative Example 2 and FIG. 20), when the width of the wing without the race is 9.0 cm (see Comparative Example 2 and FIG. 19), In the case of a width of 9.0 cm (see Example 15 and FIG. 18), there is a difference in the indoor side surface temperature and the room center temperature of the vertical blind.

  As for the surface temperature of the indoor side of the vertical blind, as shown in FIG. 16A, in the case of the width 27.5 cm (overlap width W = 1 cm) of the wing 2Q without a race (see Comparative Example 3 and FIG. 20). ) Increased from 40 ° C. (after 4 minutes) to 53 ° C. (after 1 hour).

  On the other hand, in the case of only the wing 2P without a race having a larger overlap width W (overlap width W = 2 cm) (Comparative Example 2, see FIG. 19), the temperature slightly changes and is about 38 ° C. (4 minutes). After) to about 50 ° C. (after 1 hour).

  Further, in the case where the lace bag 9P is attached and the wing with a lace has a width of 9.0 cm (overlapping width W = 2 cm) (see Example 15 and FIG. 18), it is even lower even though there is no floor clog. It changed with temperature and increased from about 34 ° C. (after 4 minutes) to about 47 ° C. (after 1 hour).

  On the other hand, regarding the room center temperature, as shown in FIG. 16 (B), in the case of a wing without a race of 7.5 cm (overlapping width 1 cm) (see Comparative Example 3, FIG. 20), 30 ° C. (4 Minutes later) to 38 ° C. (after 1 hour).

  On the other hand, in the case of the width of the laceless body having a larger overlap width of 9.0 cm (overlap width of 2 cm) (Comparative Example 2, see FIG. 19), the temperature slightly decreased and was about 30 ° C. (4 minutes). After) to about 37 ° C. (after 1 hour).

  Furthermore, in the case of the width of the wing with a lace attached to 9.0 cm (overlapping width 2 cm) (see Example 15, FIG. 18), the transition occurs at a low temperature despite no floor clogging, The temperature rose from about 29 ° C. (after 4 minutes) to about 37 ° C. (after 1 hour).

  Therefore, while adjusting the overlapping width W between the edges of the wings, it is possible to improve the heat insulation by filling at least the gap between the edges with a race or the like.

  As mentioned above, although embodiment and the Example were described about this invention, this invention is not limited to the said embodiment and Example.

  For example, in the first embodiment, the runner 3 directly grips the upper end of the wing 2 from the upper end opening of the lace bag 9, and the lace bag 9 of the slat 22 is shifted up and down in winter so that the lower end of the wing 2 and the floor It is good also as a structure which adjusts the clearance gap between surfaces.

  In this case, the lace bag 9 covers the wing 2 up and down, but when the lace bag 9 is shifted downward, there is a gap between the wings 2 and 2 above the room according to the amount of displacement. G is generated. However, since the air above the room in the vicinity is warm, this gap hardly causes a problem as a cause of the cold draft.

  A mohair-like cloth like a flange may be provided on the side edge of the lace bag 9H (see FIG. 12) of Example 11. By doing in this way, while the mohair-like cloth can fill up the gap between wings suitably, the design nature of slats can be improved.

  Instead of the mohair fabrics 5E to 5F used in Example 12 (see FIG. 13), vinyl sheet or ceramic fiber fabric may be used. By doing in this way, the heat insulation of a window edge member can be improved more.

  Moreover, it is good also as a structure which makes the magnet 20 of Example 13 adsorb | suck to the iron plate 21 as the weight 11 of Example 2 or Example 8. FIG. By doing in this way, in addition to the effect of attachment / detachment mentioned above, the number of parts can be reduced.

  Furthermore, a mohair-like cloth may be attached to the plate magnet 20 and the iron plate 21 used in Example 14. By doing in this way, the designability increases. Moreover, it is good also as a mohair-like cloth instead of the plate magnet 20 and the iron plate 21. FIG.

  The overlapping width W of the wings (see FIG. 18) is not limited to 2 cm set in the fifteenth embodiment, and may be changed in consideration of the heat insulating performance of the slats. Moreover, you may increase an overlap part by side edge parts, such as a lace bag extended further to the side from the side end surface of the wing.
