AI Technical Summary

Benefits of technology

The solution provides comfortable, aesthetically appealing, and entertaining waterproof apparel that engages the wearer with temperature- and UV-induced color changes, enhancing the appeal and usability for children.

Problems solved by technology

It is also important that waterproof apparel be comfortable to wear and aethetically pleasing and it is in this area that waterproof apparel is often less than satisfactory, particularly for children.
Children often refuse to wear traditional waterproof apparel because it is found to be cumbersome and unappealing.
Thus, children are often exposed to undesirable weather elements without benefit of protective clothing.
None of the prior art, however, discloses waterproof apparel that is made of a flexible fabric and that incorporates thermochromic properties and / or ultraviolet-sensitive properties.

first embodiment

[0023]FIGS. 1 and 2 show a waterproof apparel 10 according to the invention. The waterproof apparel 10, in this particular illustration a coat, is constructed of a flexible, PVC sheet material containing a thermochromic dye that is co-extruded with the PVC sheet material. FIG. 1 shows the waterproof apparel 10 at room temperature, having a first solid color 3 at room temperature. FIG. 2 shows the waterproof apparel 10 having a second solid color 5 after the temperature has dropped below a predefined temperature limit, such as 65 degrees Fahrenheit. It should be understood that specific temperature limits given herein are arbitrary and for purposes of illustration, and that the scope of the invention includes temperature limits within the range of possible limits of conventional thermochromic dyes and / or inks.

second embodiment

[0024]In a second embodiment, the waterproof apparel 10 is constructed of a flexible thermochromic PVC sheet material that includes a first thermochromic dye that becomes apparent at a first temperature change limit and a second thermochromic dye that becomes apparent at a second temperature change limit. For example, the flexible PVC sheet material has a base color of yellow. When the temperature drops below 65 degrees Fahrenheit, the color of the sheet material changes to blue; when the temperature rises above 72 degrees Fahrenheit, the color changes to green. It is understood that many variations of the present invention are possible, using numerous thermochromic dyes and choosing any number of feasible temperature limits.

[0025]FIGS. 3 and 4 illustrate variations of the waterproof apparel 10, depending on how the thermochromic dyes are incorporated into the PVC base material and how many colors are used. FIG. 3 shows the waterproof apparel 10 that evidences a moiré effect when th...

Abstract

Waterproof apparel constructed of a flexible PVC sheet or other polymeric flexible sheet material that changes color due to a change in ambient conditions. Thermochromic dyes and / or photochromatic dyes are incorporated into the resin mix for fabricating the flexible sheet material. The color of the waterproof apparel changes when the temperature rises above or drops below a pre-defined temperature and / or when the ultra-violet light level is above or below a pre-defined level.

Description

BACKGROUND INFORMATION[0001]1. Field of the Invention[0002]The field of the invention relates to waterproof outerwear. More particularly, the invention relates to waterproof outerwear made of flexible sheet material, such as elastomeric PVC, polyurethane elastomer, or other thermoplastic alloys, that changes its appearance as the ambient temperature changes.[0003]2. Description of the Prior Art[0004]Conventional waterproof apparel, which includes raincoats or jackets, rain hats, rain pants and footwear, is generally constructed of a waterproof material. The types of material used for such waterproof apparel include woven and non-woven material, material that is inherently waterproof, such as PVC or other polymeric extruded or calendered sheet material, as well as woven cotton material that is surface-treated with a waterproofing coating.[0005]Essentially, the purpose of waterproof apparel is to protect the wearer from the external elements. Many types of material are already known t...
