Abstract

A sanitary covering is retrofit over an existing handle or railing, particularly a shopping cart handle. A stability-enhancing element in the form of compression foam is adhesively secured to an existing handle. A metal cover, such as of anodized aluminum, with a pathogen-eliminating outer surface (such as a biocidal or antimicrobial coating), jackets the compression foam. The cover may be in two parts having elements interlocking them together so as to be securely attached together and securely engage the compression foam. A method of retrofitting a sanitary covering over an existing handle or rail is also provided utilizing a stability-enhancing element and a metal cover with a biocidal or antimicrobial outer coating.

Claims (23)

1 . A covering for a handle or railing comprising: a stability-enhancing interior element adapted to be provided over the handle or railing; and a metal cover adapted to be provided over the stability-enhancing interior element, wherein the metal cover is provided with a pathogen-eliminating outer surface; and,

wherein the metal cover comprises first and second cover components, and wherein each of the components include respective mechanically interlocking or inter-engaging elements, whereby, when installed, the first and second components are securely held together and engage the stability-enhancing interior element.

2 . The covering of claim 1 , wherein the handle or railing comprises a shopping cart handle.

3 . The covering of claim 1 , wherein said stability-enhancing interior element comprises compression foam which is adapted to operatively engage the handle or railing.

4 . The covering of claim 1 further comprising an adhesive for affixing said stability-enhancing interior element to the handle or railing and/or to the cover.

5 . The covering of- claim 1 , wherein said cover of metal comprises an anodized aluminum cover with an antimicrobial or biocidal coating on the outer surface thereof.

6 . A system for sanitizing a handle or railing comprising a retrofit covering for the handle or railing, said retrofit covering including a stability-enhancing interior element, and a cover of metal that is provided with a pathogen-eliminating outer surface,

wherein said metal cover comprises first and second components, and mechanically interlocking or inter-engaging elements which hold said first and second components securely together and engaging the stability-enhancing interior element.

7 . The system of claim 6 , wherein the handle or railing comprises a shopping cart handle.

8 . The system of claim 6 , wherein said stability-enhancing interior element comprises compression foam which operatively engages the existing handle or railing.

9 . The system of claim 6 , wherein said stability-enhancing interior element is attached to the handle or railing with an adhesive.

10 . The system of claim 6 , wherein said cover of metal comprises an anodized aluminum cover with an antimicrobial or biocidal coating on the outer surface thereof.

11 . A kit for providing a cover over a handle or railing, the kit comprising: a stability-enhancing interior element adapted to be provided over the handle or railing; and a metal cover adapted to be provided over the stability-enhancing interior element; wherein the metal cover is provided with a pathogen-eliminating outer surface,

wherein said metal cover comprises first and second cover components, and wherein each of the components include respective mechanically interlocking or inter-engaging elements, whereby, when installed, the first and second components are securely held together and engage the stability-enhancing interior element.

12 . The kit of claim 11 , wherein the handle or railing comprises a shopping cart handle.

13 . The kit of claim 11 , wherein said stability-enhancing interior element comprises compression foam which is adapted to operatively engage the handle or railing.

14 . The kit of claim 11 further comprising an adhesive for affixing said compression foam to the handle or railing, when the covering is installed.

15 . The kit of claim 11 , wherein said cover of metal comprises an anodized aluminum cover with an antimicrobial or biocidal coating on the outer surface thereof.

16 . A method for retrofitting a sanitary cover on an existing handle or railing, the method comprising:

a) adhesively securing a compression foam to layer over the existing handle or railing; and

b) providing a metal cover over the foam layer, the metal cover having an outer surface with pathogen-eliminating properties, wherein the metal cover comprises an anodized aluminum cover with an outer coating of antimicrobial or biocidal material,

wherein the metal cover is provided as two components and step b) comprises interlocking together or inter-engaging the two components of the cover over the foam layer.

17 . The method of claim 16 , wherein the handle or railing is a handle of a shopping cart.
