referring now to fig1 and 2 , there is show a preferred embodiment of a frost blanket 10 constructed in accordance with the present invention overlying an area of earth 1 ( i . e . a flower bed ) having vegetation 2 ( see fig1 ) grown / growing thereon . the frost blanket 10 includes a sheet of material 12 having folded edge portions 14 that form piping 16 . a weight ( s ) 18 is positioned within the piping 16 and assist in holding the frost blanket 10 in position over the vegetation 2 . notably , while the frost blanket 10 is shown in position over “ residential ” style landscaping plants ( i . e ., shrubs , flowering plants , fruit trees , ornamental plants , etc . ), it will be appreciated that the frost blanket 10 of the present invention has a wide range of uses , including use in connection with the protection of rural ( i . e ., farmland ), residential and commercial ( i . e ., experimental ) crops , commercial landscaping or the like . the sheet of material 12 is preferably a textile material . as such , the sheet 12 may be constructed from cotton , wool or any other available fabric or fabric blends ( include synthetic fabrics ). alternatively , the sheet 12 may be constructed of a polymeric material ( e . g ., plastic ). such polymeric materials will preferably have a plurality of micro - perforation that permits the material to “ breath ” in a manner similar to a natural ( or suitable synthetic ) textile . the sheet 12 may be colored any color or combination of colors according to the needs of the user . for example , the sheet 10 may also be colored or coated ( using means know in the art ) such that it either absorbs ( black ) or deflects ( white ) heat . additionally , the sheet 12 may be colored earth tones ( or the like ) such that the sheet 12 would blend in with the surrounding terrain or architecture . the ends or edge portions 14 of the sheet are folded over and sewn together to form a piping 16 that extends around the parameter 19 of the sheet 12 . alternatively , the piping 16 may be staggered ( see fig2 ) such that it extends only around portions of the edge 14 of the sheet 12 ( e . g ., the piping 16 may intermittently ( or irregularly ) arrayed along the parameter 19 of the sheet 12 . the weight ( s ) 18 is positioned within the piping 16 . preferably , the weight ( s ) 18 is a flexible weight such as sand , metal beads or a fluid ( i . e ., water ) that is encapsulated by the piping 16 . if a fluid is used as the weight 18 , the fluid may , for example , be stored within bags ( or the like ) that are dimensioned to fit within the piping 16 . additionally , metal rods , discs or even metal magnets may be used as the weight 18 . the weight 18 should be heavy enough to hold the blanket 10 in position over the designated vegetation ( see fig1 ) during windy environment conditions , but light also enough that the blanket 10 does not compress , crush or brake the vegetation it is intended to protect . referring now to fig3 the blanket 10 is constructed from a sheet 12 that has a generally circular pattern having piping 16 and a weight ( s ) 18 along the parameter 19 . accordingly , it is understood that the blanket 10 may be constructed in a variety of shapes ( i . e ., square , rectangle , circle , oval , star , trapezoid , parallelogram , etc .) or sizes ( i . e ., 10 ′× 10 ′, 10 ′× 100 , 25 ′× 150 ′). referring now to fig4 there is shown an alternative embodiment of the frost blanket 100 of the present invention wherein the piping 16 is positioned or extends into the interior area 20 of the sheet 12 . a weight ( s ) 18 is positioned within the piping 16 as a means of securing the sheet 12 over the vegetation ( not shown ). having thus described my invention , various modifications and improvements will become apparent to those having skill the art that do not depart from the spirit of the invention .
a method and apparatus for covering vegetation in a cold or windy environment such that the vegetation is protected from frost . the cover includes a sheet of material that has a parameter edge . the parameter edge is folded to form piping and a weight is positioned within the piping to restrain the movement of the cover when the cover is in position over the vegetation .
