in accordance with the present invention , a protective and insulating cast cover is provided . any material that is warm , stretchy , washable , breathable , and durable is suitable for the protective and insulating cast cover . furthermore , a lighter weight material such as cotton is suitable for a cover designed solely to keep the cast clean and decorated . in a preferred form , the cast cover has a composition involving a single layer of material covering most of the cast or injured limb , with a double layer of material covering the toes or other exposed areas of the limb . however , for a cover designed to accommodate a walking cast , a cut must be made in the sole of the cover . a useful material must not fray or otherwise be weakened when cut . a fleece material is the most preferred choice because it does not fray when cut . the cast cover or cover for an injured limb of the present invention combines into one design many of the advantages , which combination is lacking in the prior art . unless otherwise specified , cast cover and cover for an injured limb are used interchangeably . there are at least six outstanding advantages of this cast cover . first , the cast cover protects exposed areas of the limb from cool or inclement weather . second , the cast cover helps to keep exposed areas of the limb clean . third , the cast cover is easily put on and removable to prevent pain and movement in the foot . fourth , a fleece cast cover can be cut to accommodate a walking cast without fraying . fifth , the cast cover can adjust to different sizes of casts so that it is not bulky or unsightly . sixth , the cast cover is washable . referring now to fig1 , fig2 , and fig3 , a protective and insulating cast cover 100 is placed over a limb in a cast 102 . the cast cover 100 is composed of material 104 that is both insulating and elastic . the insulating nature of the material 104 ensures that exposed areas of the limb will be protected from inclement weather . the difference between fig1 and fig3 is in the tab position . top ankle tab 146 and bottom ankle tab 126 can secured to each other in fig1 . in fig3 , on the tongue 136 is hook and loop assembly 150 to receive top ankle tab 146 and bottom ankle tab 126 . referring now to fig4 , both the protective and insulating nature of cast cover 100 become clear . a majority of the cast is covered by a single piece of the material 104 . this covering helps to keep the cast clean and dry and also serves a decorative purpose . top toe panel 160 in top panel 140 and bottom toe panel 166 in bottom panel 120 provide and extra layer of protection and insulation for the exposed areas of the limb . referring now to fig5 , one feature of cast cover 100 is the hook and loop assembly 150 . the flexible nature of the material 104 and the hook and loop assembly 150 make it easy to put on and remove the cover and thus , reduce foot movement and pain in the process . the hook and loop assembly 150 can be undone to provide maximum room for sliding into or removing cast cover 100 . furthermore , the elasticity of the material 104 means that the cover 100 can be stretched to accommodate different sizes of cast 106 . bottom ankle tab 126 and top ankle tab 146 can be adjusted as fasteners on tongue 136 to ensure a snug fit around the ankle . thus , cast cover 100 is well fitted and not bulky or unsightly . top panel 140 includes top ankle tab 146 with top toe end 148 oppositely disposed therefrom . likewise , bottom panel 120 has bottom ankle tab 126 with bottom toe end 128 oppositely disposed therefrom . top ankle tab 146 and bottom ankle tab 126 can secure to each other ( fig5 ) or to the tongue 136 if desired and hook and loop assembly 150 is present ( fig3 ). referring now to fig6 and fig7 , bottom panel 120 and top panel 140 adds to the well fitting nature of cast cover 100 . bottom panel 120 is designed to allow the material 104 to adjust to the contour of the heel . top panel 140 allows cast cover 100 to adjust to the curves on the top portion of the limb . therefore , cast cover 100 is decorative instead of bulky and unsightly . furthermore , there is not an excess of material that can cause tripping or injury . for example , when the limb is a foot , bottom panel 120 extends over the sole of the foot and up the heel . the top panel 140 extends over the foot with the tongue 136 extending up the shin . bottom ankle tab 126 and top ankle tab 146 reach over tongue 136 and are secured thereto or to each other by hook and loop assembly 150 ( fig5 ). referring now to fig8 and fig9 , the extra insulation and protection from top toe panel 160 and bottom toe panel 166 become clear . both top toe panel 160 and bottom toe panel 166 are secured top side of cover 162 , bottom side 164 bottom toe panel : 166 this added layer helps to ensure that exposed areas of the limb stay clean , warm , and dry . with fig1 , the optional form , a rubber sole 110 is incorporated into the bottom of the cast cover 100 . the rubber sole 110 provides traction , durability , and extra protection on the bottom of cast cover 100 . thus , a person who is able to walk on the injured limb can use the invention on outdoor , rough , or slick surfaces without risking further injury . with fig1 protective and insulating cast cover 100 includes an elastic panel 170 extending partially along the area , where bottom panel 120 and top panel 140 separate at panel seam 142 . elastic panel 170 combines with the stretchable material of protective and insulating cast cover 100 in order to an even greater ease putting on or taking off the same . in fig1 , tongue 136 of top panel 140 is extended into a foldable tongue panel 180 . pleat 182 adds more material and padding for the top of protective and insulating cast cover 100 . thus , increased protection is added to the limb protected thereby . this application — taken as a whole with the abstract , specification , claims , and drawings being combined — provides sufficient information for a person having ordinary skill in the art to practice the invention as disclosed and claimed herein . any measures necessary to practice this invention are well within the skill of a person having ordinary skill in this art after that person has made a careful study of this disclosure . because of this disclosure and solely because of this disclosure , modification of this method and device can become clear to a person having ordinary skill in this particular art . such modifications are clearly
