Abstract

Thermal energy retaining means for use in covering soil adjacent growing plants and including a water tight elongated tubular sleeve enclosure having support means at opposed ends thereof. The support means consist of planar means or generally inverted "U" shaped configuration, and each comprising a pair of generally parallelly disposed legs spaced apart by an upper fixed cross-member. A second cross-member, slidably coupled to the legs of the inverted "U" shaped bracket is provided which extends generally parallel to the upper cross-member to form a jaw to receive the tubular sleeve material therebetween. After filling with water, the width of the tubular sleeve material is placed within the jaw of the hanger means, the hanger means then being rotated about the sleeve so as to seal the ends of the sleeve and adjust the axial length thereof.

Dependent claims

In a thermal energy retaining means for use in covering soil adjacent growing plants and having a water tight elongated tubular sleeve enclosure of plastic film with open ends and with support means at opposed ends thereof and being further characterized in that:

a. said support means comprising hanger means at opposed ends of said elongated tubular sleeve and comprising a generally inverted "U" shaped bracket with a pair of generally parallelly disposed spaced apart legs with a first cross-member extending between said legs at the top thereof;
b. a second cross-member slidably coupled to the spaced apart legs of said "U" shaped bracket and extending generally parallel to said first cross-member to form a jaw with said first member when adjacent thereto to receive said elongated tubular sleeve therebetween;
and
c. the length of said cross-members being at least equal to the width of said elongated tubular sleeve and being arranged to form a winding core for the opposed open ends of said tubular sleeve for sealing the ends and adjusting the axial length thereof.
