Sheet with weight

Abstract

A sheet with weight preventing the leakage of rainwater with easy operation. The sheet with weight comprises a sheet portion and a weight mounted along an edge of said sheet portion. The sheet may be accommodated in a cylindrical portion integrally formed along the edge of the sheet portion, and the weight can be a metal chain.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] The present application claims priority to Japanese Utility Model Application No. 2001-1949 entitled SHEET WITH WEIGHT filed on Apr. 6, 2001.

STATEMENT RE: FEDERALLY SPONSORED RESEARCH/DEVELOPMENT

[0002] (Not Applicable)

BACKGROUND OF THE INVENTION

[0003] The present invention relates to a sheet with weight, and more particularly to a sheet with weight preferably used for a roof of a house broken by an earthquake or the like.

[0004] In case that a roof of a house is broken due to an earthquake or the like, the broken portion is usually covered by a plastic sheet or the like to prevent the leakage of rainwater. Since merely covering the broken portion by the sheet allows the sheet to be blown away due to wind, sand bags or the like are put on the sheet.

[0005] With the above-mentioned conventional method, however, the portions without sand bags blow hard in wind, and rainwater enters from these portions into the house. In order to prevent leakage, it is possible to stick the sheet fast to the surface of the roof without a gap utilizing string, adhesive tape and so on. But, in this case, scaffolding or the like is necessary, and it takes a long time to cover the broken portion with the sheet.

BRIEF SUMMARY OF THE INVENTION

[0006] It is therefore the object of the present invention to provide a sheet with weight to prevent the leakage of rainwater or the like with easy operation.

[0007] To accomplish the above objective, the sheet with weight according to the present invention comprises: a sheet portion; and a weight mounted along an edge of said sheet portion. With the above sheet with weight, only transporting the sheet to the place where the sheet is used and spreading it at the place allows the overall or partial edge of the sheet to be stuck fast to the place, which prevents the leakage of rainwater or the like.

[0008] In the sheet described above, the weight can be accommodated in a cylindrical portion integrally formed of the edge of the sheet portion. It is very convenient to form the weight so as to be replaceable from the cylindrical portion.

[0009] In the sheet described above, the weight can be produced by a metal chain, which makes it possible to construct the sheet using ordinarily used metal.

BRIEF DESCRIPTION OF THE DRAWINGS

[0010] The present invention will be more apparent from the ensuing description with reference to the accompanying drawings wherein:

[0011] FIGS. 1A and 1B are a partially sectional plan view and a sectional view observed from the line A-A; and

[0012] FIG. 2 is a schematic perspective view showing a usage of the sheet with weight illustrated in FIGS. 1A and 1B.

DETAILED DESCRIPTION OF THE INVENTION

[0013] Now, a preferred embodiment of the present invention will be explained with reference to the drawings.

[0014] FIGS. 1A and 1B show a sheet with a weight (hereinafter referred to as the “sheet”) according to one embodiment of the present invention. The sheet 1 comprises: a sheet portion 2 made from resin; cylindrical portions 3 at upper and lower, right and left edges of the sheet portion 2; a metal chain 4 accommodated in the cylindrical portions 3.

[0015] The sheet portion 2 has the shape of a rectangle, and is preferably made from resin. It is possible to make the sheet portion 2 of waterproof cloth. The sheet portion 2 is preferably foldable for transportation.

[0016] The cylindrical portions 3 are formed to easily accommodate the metal chain 4 and eliminate the gap between the edges of the sheet portion 2 and the roof where the sheet 1 is put. Besides cylindrical shapes, other shapes will do as long as the metal chain 4 is accommodated at the overall edge of the sheet portion 2. The metal chain 4 can partially be exposed.

[0017] The reason why the metal chain 4 is used as a weight is that it is convenient for transportation and storage with the sheet 1 being folded. But, it is possible to use short metal rods or the like if it is easy to fold the sheet portion 2. Cylindrical plastic capsules with water therein may also be used as a weight.

[0018] FIG. 2 shows a usage of the sheet 1 with the above-mentioned construction to prevent the leakage of rainwater by covering a broken portion 5 of a roof of a house. With this sheet 1, only transporting the sheet 1 to a roof and spreading the sheet 1 to cover the broken portion 5 allows the overall edge of the sheet 1 to be stuck fast to the surface of the roof, which prevents the leakage of rainwater.

[0019] If the metal chain 4, illustrated in FIG. 1 of sheet 1, is too heavy, it is not easy to carry the sheet 1 to the roof. The weight of the metal chain 4 of the sheet 1 is preferably selected such that the sheet 1 may be easily carried and, when adjusted so that the sheet 1 covers the broken portion 5, the edges are not lifted by wind.

[0020] Although the metal chain 4 is accommodated at the overall edge to eliminated the gap between the overall edge of the sheet portion 2 and the surface of the roof in the above embodiment, it is possible to partially mount the metal chain 4 to the edge of the sheet portion 2 to partially stick the sheet portion 2 fast to the surface of the roof.
