Description

  The present invention relates to a seat that is installed on a partition or a staircase without a door and used to prevent the intrusion of cool air from the outside of the room in the winter and the outflow of cool air from the inside of the room to the outside in the summer.

  Traditionally, in winter, curtains have been installed on partitions and stairs without doors to prevent cold air from entering the room where the room temperature is adjusted. Moreover, by providing curtains on partitions and stairs without doors even in summer, it is possible to prevent cold air from flowing out of the room where the room temperature is adjusted. For example, in many cases, a curtain rail or a bar is installed between a partition without a door or a wall at the top of a staircase, and the curtain is hung on the curtain rail or the bar. However, when a curtain is installed, there is a problem that if the curtain is moved to one side when passing through a partition without doors or stairs, the curtain cloth becomes bulky and the passage becomes narrow.

Therefore, a coarse warp portion in which at least one warp yarn does not exist is formed at a specific portion of a woven fabric (sheet for preventing intrusion and outflow of cold air) formed of warp and weft as in Patent Document 1, and the coarse warp portion A woven fabric is disclosed in which the accordion shape is easily formed by bending the fold. When folding, the coarse warp part that is the crease has no warp, so it is softer than other parts and can be folded easily, using many parts that were conventionally required for making an accordion shape The accordion-shaped woven fabric can be made without much cost and cost. By installing the woven fabric of Patent Document 1 on a partition or staircase without a door, when the woven fabric is moved to one side when passing, the problem that the passage is narrowed has been solved.
However, since cold air tends to accumulate in the lower part of the room, it is necessary to adjust the length of the woven fabric (cold air intrusion and outflow prevention sheet) according to the height of the installation place. When the woven fabric of Patent Document 1 is longer than the height of a partition without doors or a staircase, it is necessary to cut the woven fabric. When cutting, if the cutting line is bent and the section of the woven fabric is bent straight, the weft of the woven fabric is cut and frayed. Often occurred. Therefore, a coarse warp portion where at least one warp yarn does not exist and a coarse weft portion where at least one weft yarn does not exist are formed in a specific portion of the woven fabric formed of warp yarns and weft yarns as shown in FIG. Woven fabrics (cold intrusion and outflow prevention sheets) are known.

  However, in the woven fabric (sheet for preventing intrusion and outflow of cold air) as shown in FIG. 8, the coarse warp portion and the coarse weft portion are provided at equal intervals (about 10 cm) over the entire region in the height direction. Yes. When the height of the partition or the staircase without the door is between the coarse weft portion and the coarse weft portion, it is necessary to cut the woven fabric at a portion where the coarse weft portion is not provided. In this case, similarly to the woven fabric of Patent Document 1, when cutting, it cannot be cut straight, the cutting line is bent, or the portion where the texture of the woven fabric is bent is cut linearly. As a result, the weft yarn of the woven fabric is cut and fraying occurs. In addition, there is a problem in that cold air enters or flows out of the gap because a gap is formed between the floor and the lower end of the woven fabric when the coarse weft part at a position shorter than the height of the partition or staircase without a door is cut. It was.

  Therefore, a main object of the present invention is to provide a sheet for preventing intrusion and outflow of cool air that can adjust the length of the sheet at the lower side of the sheet in accordance with the height of the installation place.

(Cold air intrusion and outflow prevention sheet 10)
A cold intrusion and outflow prevention sheet 10 according to the present invention will be described with reference to FIG. FIG. 1 is a front view of a cold air intrusion and outflow prevention sheet according to the present invention.

  Here, in FIG. 1, when the cold air intrusion and outflow prevention sheet 10 is installed, the longitudinal direction of the cold air intrusion and outflow prevention sheet 10 is the vertical direction, and the cold air intrusion and outflow prevention sheet 10 is short. The direction that is the hand direction is the left-right direction.

  The cold intrusion and outflow prevention sheet 10 according to the present invention has a rectangular shape and a thin flat shape. In particular, when the cool air intrusion and outflow prevention sheet 10 is installed, it is desirable that the length in the vertical direction is longer than the length in the horizontal direction. When the cold air intrusion and outflow prevention sheet 10 is viewed from the front, the upper side is the upper side 10a, and the side opposite to the upper side 10a is the lower side 10b. Further, when the cold intrusion and outflow prevention sheet 10 is viewed from the front, the left side is defined as the left side 10c, and the side facing the left side 10c is defined as the right side 10d. The cold intrusion and outflow prevention sheet 10 is, for example, a sheet having a vertical length of 200 cm and a horizontal length of 100 cm.

  The cold intrusion and outflow prevention sheet 10 includes a ground structure 12 and a hanging portion 14. The ground structure 12 and the hanging part 14 are integrally formed. The cold intrusion and outflow prevention sheet 10 is a sheet made of polyester, acrylic, rayon, cotton, or a resin sheet such as vinyl, for example. The cold air intrusion and outflow prevention sheet 10 improves the heat insulating effect by sticking a resin film or sheet to a knitted or woven yarn, or impregnating the resin, thereby further intruding the cold air. Can prevent spillage. In particular, the cold air intrusion and outflow prevention sheet 10 is preferably a sheet that can be cut with scissors or the like. Moreover, the sheet | seat provided with a water repellent process, light shielding, a flameproof function, etc. may be sufficient. When the cold intrusion and outflow prevention sheet 10 is formed of yarn, for example, yarn having a diameter of 10 μm to 30 μm is used. For example, as shown in FIG. 7B, the cold air intrusion and outflow prevention sheet 10 is knitted by bridging the weft 34 between the longitudinal support yarn 36 a and another adjacent support yarn 36 b. Further, the ground structure 12 of the cold intrusion and outflow prevention sheet 10 has translucency, and for example, a lace pattern may be formed. Therefore, even if the cold intrusion and outflow prevention sheet 10 is installed, a feeling of blockage is not felt. Moreover, the state of the other side can be indirectly seen through the intrusion and outflow prevention sheet 10 of the cold air, and the installation can be performed with security even in the crime prevention aspect.

The cold intrusion and outflow prevention sheet 10 is provided with a plurality of longitudinal cutting portions 22 in parallel with the longitudinal direction which is the vertical direction. Further, the longitudinal cutting portions 22 are provided continuously from the upper side portion 10a to the lower side portion 10b of the cold air intrusion and outflow prevention sheet 10, and are provided at equal intervals in the left-right direction of the cold air intrusion and outflow prevention sheet 10. It has been. The space | interval of a vertical direction cutting part is about 10 cm, for example. The vertical direction cutting part 22 is shown with a broken line for convenience except for FIG.
When the cold air intrusion and outflow prevention sheet 10 is formed of yarn, the longitudinal direction cutting portion 22 is knitted and formed every three stitches as shown in FIG. 7A, for example. In addition, the left side portion 10c and the right side portion 10d of the cold air intrusion and outflow prevention sheet 10 and the non-knitted portion of the longitudinal cutting portion 22 are subjected to fraying prevention processing. The fraying prevention process is a process of, for example, knitting the ends of the yarn into the ground structure or hardening the ends with an adhesive or the like in order to prevent the ends from fraying.
In addition, when the cold air intrusion and outflow prevention sheet 10 is formed of a resin sheet, the longitudinal cutting portion 22 is formed by cutting in a broken line shape, for example.
Therefore, the longitudinal direction cutting part 22 is formed more coarsely than the part of the other cold intrusion and outflow prevention sheet 10, and can be bent softly and easily. By providing the vertical cutting part 22, it can be easily folded in the left-right direction. Further, even when the installation place is narrow, by cutting along the longitudinal cutting portion 22, the length of the cold intrusion and outflow prevention sheet 10 in the left-right direction can be shortened.

Further, the cold air intrusion and outflow prevention sheet 10 is provided with a plurality of transverse cut portions 32 perpendicular to the longitudinal direction which is the vertical direction. The transverse cut portion 32 is provided continuously from the left side portion 10c to the right side portion 10d of the cold air intrusion and outflow prevention sheet 10. The horizontal direction cutting part 32 is shown with a broken line for convenience except for FIG.
When the cold air intrusion and outflow prevention sheet 10 is formed of yarn, the transverse cutting portion 32 thins out the weft yarns 34 in parallel, for example, as shown in FIG. Therefore, the transverse cut portion 32 has only the support yarns 36 in the longitudinal direction, and the thickness of the fabric is thinner than other portions. Further, fraying prevention processing is performed on the weft 34 adjacent to the transverse cut portion 32.
Further, in the transverse cut portion 32, as shown in FIG. 7B, the upper weft yarn is placed on the upper critical edge 34a and the lower weft yarn is placed on the lower critical edge 34b across the transverse cut portion 32. And A space between the upper critical edge 34a and the lower critical edge 34b can be cut by scissors or the like, and extends from the left side 10c to the right side 10d of the cold intrusion and outflow prevention sheet 10. Are provided continuously. Further, in the horizontal direction cutting portion 32, the space of the horizontal direction cutting portion 32 is supported by the vertical support yarn 36a and another adjacent support yarn 36b. The support yarn 36a in the vertical direction and the other support yarn 36b adjacent to each other are parallel to each other. The lateral critical edges 34a and 34b and the longitudinal support yarns 36a and 36b are orthogonal to each other.
In addition, when the cold air intrusion and outflow prevention sheet 10 is formed of a resin sheet, the lateral cutting portion 32 is formed by cutting in a broken line shape, for example.
Therefore, the transverse cut portion 32 is formed to be rougher than the other cold air intrusion and outflow prevention sheet 10 and can be bent easily and softly. Further, even when the installation place is low in height, by cutting the cold air intrusion and outflow prevention sheet 10 along the transverse cut portion 32, the vertical length of the cold air inflow and outflow prevention sheet 10 can be reduced. The length can be shortened. Therefore, the length of the cold intrusion and outflow prevention sheet 10 in the vertical direction can be finely adjusted according to the height of the installation place, and from between the lower side 10b of the cold intrusion and outflow prevention sheet 10 and the floor. Intrusion or outflow of cold air can be prevented.

Further, the geological structure 12 of the cold intrusion and outflow prevention sheet 10 is, for example, a first area 40 where the distance between the horizontal cutting parts 32 is wide and the distance between the horizontal cutting parts 32 is medium. The region is divided by three different types of intervals, the second region 42 that is a region of the second region 42 and the third region 44 that is a region in which the interval between the horizontal cut portions 32 is narrow.
The first region 40 is a portion below the upper side portion 12a of the ground structure 12, and is a region where the interval 40a between the lateral cut portions 32 is wide. The first area 40 occupies about 45% of the cold intrusion and outflow prevention sheet 10. By cutting the cool air intrusion and outflow prevention sheet 10 at the horizontal cutting portion 32 at the lower end of the first region 40, the vertical length of the cold air intrusion and outflow prevention sheet 10 is about 90 cm. Therefore, it can be installed in an opening such as a waist high window having a height of about 90 cm.
The second region 42 is a portion below the first region 40 from the lower end, and is a region where the interval 42a of the lateral cut portion 32 is medium compared to other regions. The second region 42 occupies about 40% of the cold intrusion and outflow prevention sheet 10. In the second region 42, the horizontal cutting portions 32 are provided at equal intervals, and the interval 42a between the horizontal cutting portions 32 in the second region is, for example, about 10 cm. By cutting the cold intrusion and outflow prevention sheet 10 at the transverse cutting portion 32 provided in the second region 42, the vertical length of the cold intrusion and outflow prevention sheet 10 is about 90 cm to about 180 cm. Adjustment is possible every about 10 cm. Therefore, it can be installed in an opening such as a waist high window having a height of about 90 cm to about 180 cm.
The third region 44 is a region below the second region 42 from the lower end, and is a region where the interval 44a of the lateral cut portion 32 to the lower side portion 12b of the ground texture 12 is narrow. The third region 44 occupies about 10% of the cold intrusion and outflow prevention sheet 10. In the third region 44, the transverse cut portions 32 are provided at equal intervals, and the interval 44a between the transverse cut portions in the third region is, for example, about 3 cm. By cutting the cold intrusion and outflow prevention sheet 10 at the lateral cutting portion 32 provided in the third region 44, the vertical length of the cold intrusion and outflow prevention sheet 10 is about 180 cm to about 200 cm. Adjustment is possible every 3 cm. Therefore, it can be installed at the doorway such as an opening without a door or a staircase having a height of about 180 cm to about 200 cm.
Accordingly, the length of the cold air intrusion and outflow prevention sheet 10 in the vertical direction can be finely adjusted according to the height of the installation place.

The hanging portion 14 of the cold air intrusion and outflow prevention sheet 10 is formed, for example, on the upper side portion 12 a of the ground structure 12 via the lateral cutting portion 32. The hanging portion 14 occupies about 5% of the cold air intrusion and outflow prevention sheet 10. The hanging portion 14 is provided with an elliptical opening hole portion 16 whose major axis is the vertical direction for each region 24 delimited by the vertical direction cutting portion 22. The shape of the opening hole 16 is not limited to an ellipse, and can take various shapes such as a circle and a triangle. By passing the rod 70 through the opening hole portion 16 and installing it between the entrance / exit ports and the height direction supporting members 60, 60 of the opening portion, the cold intrusion and outflow prevention sheet 10 can be suspended.
If the hanging part 14 is not formed, a clip with an annular attachment is attached to the upper side 12a of the ground structure 12, and the annular attachment is passed through a bar, a curtain rail, etc. The outflow prevention sheet 10 can be suspended.

(Method for producing cold intrusion and outflow prevention sheet 10)
When the cold air intrusion and outflow prevention sheet 10 is knitted with yarn, it is knitted by, for example, a warp knitting machine. The opening hole part 16, the longitudinal direction cutting part 22, and the horizontal direction cutting part 32 are formed at the time of knitting by setting the position for needle removal.
Further, when the cold air intrusion and outflow prevention sheet 10 is knitted with a resin sheet or the like, for example, a hole is formed in the sheet to provide an opening hole 16, and the longitudinal cutting part 22 and the lateral cutting part 32 are cut. It is formed by putting in.

For example, as shown in FIG. 2A, the cold air intrusion and outflow prevention sheet 10 can pass through a partition 70 without a door and the interior of a staircase through a bar 70 through the opening hole 16 of the hanging portion 14. A sheet is installed between the height direction supporting members 60 and 60 of the entrance and the opening.
First, the rod 70 is passed through the opening hole 16 of the hanging portion 14.
Next, the bar 70 is installed between the partition members without doors and the height direction support members 60 at the top of the stairs. At this time, it is preferable to install so that there is no gap between the partition without a door or the lateral support member 62 at the top of the stairs and the upper side portion 10a of the cold air intrusion and outflow prevention sheet 10.
Finally, as shown in FIG. 4, the lower side portion 10b of the cold air intrusion and outflow prevention sheet 10 is cut by the scissors 72 or the like along the lateral cut portion 32 so as to meet the installation location. At this time, as shown in FIGS. 2B and 5, intrusion of cold air is prevented in order to prevent cold air from entering or flowing out between the lower side portion 10 b of the outflow prevention sheet 10 and the floor. And it is preferable to cut to a length that the outflow prevention sheet 10 bends. In addition, as shown in FIG. 6, when the cold air intrusion and outflow prevention sheet 10 is installed at the entrance of a house such as a waist high window or a bay window, the lower side portion 10b of the cold air intrusion and outflow prevention sheet 10 and the lateral opening member In order to prevent cold air from entering or flowing out from between the two, it is preferable to cut longer than the position of the lateral opening member 64.
In addition, when the width of the installation place is narrow, the intrusion and outflow prevention sheet 10 for cold air can be narrowed by cutting along the longitudinal cutting portion 22.

(effect)
In Japanese residences, doors are often about 180 to 250 cm high.
As shown in FIG. 8, the conventional cold intrusion and outflow prevention sheet 80 (conventional woven fabric) is provided with a transverse cutting portion 92 for adjusting the vertical length in units of about 10 cm. . However, the length in the height direction (vertical direction) could only be adjusted in units of about 10 cm, and a gap was formed between the lower side 80b of the cold air intrusion and outflow prevention sheet 80 and the floor. Cold air entered the space on the other side partitioned by the intrusion and outflow prevention sheet 80 from the gap. In addition, the conventional cold air intrusion and outflow prevention sheet 80 may be cut at a portion where there is no lateral cutting portion 92 so that there is no gap between the conventional cold air intrusion and outflow prevention sheet 80 and the floor, The lower side 80b of the conventional cold air intrusion and outflow prevention sheet 80 rubs against the floor, so that the lower side 80b of the cold intrusion and outflow prevention sheet 80 may be frayed.
