It is a perspective view which shows the state which passed the rope through the edge of the water shielding sheet | seat of FIG. It is a figure which shows the state which covered the television with the water-impervious sheet. It is a figure which shows other embodiment of this invention.

  An embodiment of the present invention will be described below. FIG. 1 is a perspective view showing an overall configuration of a water shielding sheet according to an embodiment of the present invention.

  With reference to FIG. 1, the water-impervious sheet 10 has a rectangular fabric 11 and a plurality of holes 15 provided on the outer peripheral portions of the four sides of the fabric 11. The fabric 11 is composed of a knitted fabric, a woven fabric, a woven mesh composite, or a non-woven fabric. The fabric 11 is covered with a resin having a waterproof property and a flameproof performance that does not spread even if it is ignited. The fabric 11 may include a film. An endless rope (not shown) is inserted into the hole 15. An endless rope is obtained by connecting both ends of a single rope, but the connecting portion is smooth without having a protruding portion.

  The plurality of holes provided in the fabric may be configured to form holes that are spaced by changing the structure of the plurality of yarns constituting the fabric at predetermined intervals at the end of the fabric. . Moreover, the shape of this hole is arbitrary, and it may be a round hole as shown or a square hole.

  Next, another embodiment of the plurality of holes will be described. FIG. 2 is a view showing a water shielding sheet according to another embodiment. Here, the water-impervious sheet includes a rectangular cloth and a ladder-shaped opening provided around the cloth. 2A is a perspective view, FIG. 2B is a sectional view of a portion indicated by an arrow IIB-IIB in FIG. 2A, and FIG. 2C is an arrow C in FIG. FIG. 2D is an enlarged view of a portion shown, and FIG. 2D is an enlarged view of a portion indicated by IID-IID in FIG.

  With reference to FIG. 2, the water-impervious sheet 10 includes a rectangular fabric 11 and rope passage portions 12 provided on four sides of the outer periphery of the fabric 11. Each of the rope threading portions 12 includes an outer peripheral cord portion 12a knitted with a raschel net or a knitted fabric, an inner peripheral cord portion 12b facing the outer peripheral cord portion 12a, an outer peripheral cord portion 12a, and an inner peripheral cord portion 12b in the longitudinal direction. And a connecting string portion 12c for connecting them at intervals. Since the rope threading portion 12 is configured as described above, it has a ladder shape as shown in FIG.

  As shown in FIG. 2 (C), the outer peripheral string portion 12a, the inner peripheral string portion 12b, and the connecting string portion 12c have substantially the same thickness.

  2C, the lower side of the end portion of the fabric 11 and the connecting string portion 12c are integrated by welding or sewing. Details of the welded or sewn portion are shown in FIG. Referring to FIG. 2D, the fabric 11 is connected to a ladder-like rope threading portion 12 at the outer peripheral portion thereof. In the figure, the portion indicated by a two-dot chain line adjacent to the rope threading portion 12 is the outer peripheral portion of the fabric, the one-dot chain line is a portion where only the fabric is present, and the dotted line between the one-dot chain line and the two-dot chain line is A welded or sewn portion 13 is shown.

  In addition, as water resistance performance of the fabric 11, it is preferable that it is 5-100 kPa. More preferably, it is 20-45 kPa. More preferably, it is 25-35 kPa.

  When the pressure is less than 10 kPa, the waterproof property is poor, and water may leak inside the cloth coating. On the other hand, if it exceeds 100 kPa, the mass of the fabric increases, making it difficult to handle, or in the case of a fabric having a small mass per unit area, the cost becomes high.

In addition, the flameproof performance must conform to the flameproof articles of the Japan Flameproof Association. There are 45 ° micro burner method and 45 ° coil method as test methods for flameproof articles, and both tests must meet the evaluation criteria. Evaluation criteria by the 45 ° micro burner method are after flame time (until flame disappears on the sheet until it disappears) 3 seconds or less, remaining dust time (until the sheet starts to turn red and the sheet has turned red) For 5 seconds or less, the area where the fabric is carbonized by the flame becomes 30 cm ² or less. In addition, in the 45 ° coil method, the number of times until a flame comes into contact with a 10 cm sheet and extinguishes must be three or more.

  Next, a state where the rope 20 is passed through the rope threading portion 12 of the water shielding sheet 10 will be described. FIG. 3 is a diagram showing this state. Here, the rope 20 is indicated by a dotted line. As shown in FIG. 3, the rope 20 is provided so that when the upper side of one of the adjacent portions passes through the plurality of connecting string portions 12 c constituting the ladder, the adjacent portion passes the lower side. ing. Therefore, the rope 20 does not fall off from the rope threading portion 12.

  Moreover, the rope 20 has a connection part to which both ends of one rope are connected, and the connection part does not have a protruding part. That is, at first glance, it does not have a knot, and smoothly moves through an opening formed by adjacent connecting string portions. Therefore, it is possible to easily squeeze the edges of the four sides of the fabric 11 with the rope 20 by covering the water shielding sheet 10 with the article and pulling a part of the rope.

  Next, a method for using the water shielding sheet 10 will be described. FIG. 4 is a view showing a method of using the water shielding sheet 10. With reference to FIG. 3, here, a case where the liquid crystal television is covered with the water shielding sheet 10 will be described.
