DETAILED DESCRIPTION

[0013] The present invention comprises a waterproof, perimeter-weighted blanket for use by law enforcement officers, firefighters, EMS personnel, paramedics, EMT's and Crime Scene officers. The purpose of the blanket is to protect the identity of the deceased in a public setting from exposure to the media and onlookers.

[0014] FIG. 1 shows a plan view of a first example of a weighted blanket 10, according to the present invention. The blanket/tarp 10 can have a square or rectangular shape. In a square shape, the blanket can be 7 ft7 ft. In a rectangular shape, the blanket can be 4 ft7 ft in size, for example, sufficient to completely cover a deceased body 4.

[0015] FIG. 2 shows a cross-section view (Sec. A-A) of a first example of a weighted blanket 10, according to the present invention. The edges of the blanket are hemmed, with a hem 8 and the hemmed region 12 is filled with a dense, heavy material 13. The dense, heavy material 13 can be a gel-like material, or a granular material like sand, BB-balls, steel balls, steel rods, steel strips, or tungsten balls. The dense material 13 can have a density greater than or equal to about 7 gm/cm.sup.3. The weighted blanket 10 has a top layer 14 and an opposing bottom layer 16 with different materials on the two different layers.

[0016] FIG. 3 shows a plan view of a second example of a weighted blanket 10 with reflective patches 18, according to the present invention. The top side comprises a continuous, waterproof plastic material 14 (such as Mylar, polyethylene, polyurethane, or equivalent waterproof polymeric material) that optionally can be colored bright orange or lime green, or partially covered with orange/green stripes of a sticky tape adhesively attached to the top layer.

[0017] FIG. 4 shows a plan view of a third example of a weighted blanket 10 with reflective stripes, according to the present invention. The top layer can optionally comprise a plurality of silverly reflective stripes 20. The bottom layer comprises a water/fluid-absorbing, felted or woven or spun material 16 similar to those used in infant or adult diapers, which is bonded at multiple places to the blanket's top side. Materials used for the absorbent bottom layer can be selected from the group consisting of natural cotton, polypropylene, and sodium polyacrylate.

[0018] FIG. 5 shows a cross-section view (Sec. A-A) of a fourth example of a weighted blanket 10 comprising a 2-ply layer, according to the present invention. Alternatively, the top layer 14 can additionally comprise a woven, cloth-like material used primarily for strength (e.g., made from Nylon or Kevlar or Spectra or other fiber to increase the tear strength of the blanket). Alternatively, the top layer can be made of a composite of two layers, (two-ply), with one ply comprising a thin, waterproof plastic sheet of material 24, and the other ply comprising a thicker, woven, cloth-like material 22 primarily for strength. The top ply 24 can be bonded to the cloth-like lower ply 22, with, for example, ultrasonic (friction) spot welding.

[0019] FIG. 6 shows a cross-section view (Sec. A-A) of a fifth example of a weighted blanket 10 comprising a 3-ply layer, according to the present invention. The inner ply 24 is made of a waterproof plastic material, while the upper ply 26 and the lower ply 22 are made of a thicker, woven, cloth-like material used primarily for strength. The top ply 24 can be bonded to the cloth-like lower ply 22 and upper ply 26, with, for example, ultrasonic (friction) spot welding.

[0020] FIG. 7 shows a cross-section view (Sec. A-A) of a sixth example of a weighted blanket 10 comprising a fiber-reinforced plastic layer, according to the present invention. Alternatively, the top layer can be made of a fiber-reinforced, anti-tear, square/rectangular or hexagonal mesh of high-strength polymeric fibers encased or embedded in a continuous plastic substrate.

[0021] FIG. 8 shows a plan view of a seventh example of a weighted blanket 10 with 4 attached handles 30, 30 and a heavy-duty zipper 32, according to the present invention. Optionally, a heavy-duty zipper 32 can be placed around the perimeter 12 of the blanket 10, in order to turn the blanket into a sealed body-bag. Alternatively, a plurality of 2-4 handles 30, 30 (e.g., made of, or reinforced with, Nylon or Kevlar fabric) can be attached by sewing the handles 30, 30 to the blanket 10 to make carrying the deceased body 4 easier when the blanket 10 used as a body bag.

[0022] The weighted blanket 10 of the present invention can also be used as a thermal blanket for living subjects exposed to cold weather. Also, the width of the hemmed perimeter 12 can range from 2 to 4, depending on the density of the dense material filling the hemmed region 12.

[0023] It is noted that the embodiments reside primarily in combinations of components and procedures related to the system. Accordingly, the system components have been represented where appropriate by conventional symbols in the drawings, showing only those specific details that are pertinent to understanding the embodiments of the present disclosure so as not to obscure the disclosure with details that will be readily apparent to those of ordinary skill in the art having the benefit of the description herein.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.
