Claim:
A handle adaptor for assisting a user to operate an existing cart safely and easily, said handle adaptor comprising: a lower member having first and second upper surfaces provided with inner edges extending inwardly from outer faces of said lower member and terminating proximal to a center of said lower member, said lower member further having third and fourth upper surfaces monolithically formed with said inner edges of said first and second upper surfaces respectively and oriented orthogonal thereto, said third and fourth upper surfaces having inner edges extending inwardly from said inner edges of said first and second upper edges and further terminating proximal to the center of said lower member, said inner edges of said third and fourth upper surfaces being disposed below said inner edges of said first and second upper surfaces, said lower member further having a fifth upper surface monolithically formed with said inner edges of said third and fourth upper surfaces respectively and positioned therebetween, said fifth surface being located subjacent to said first and second upper surfaces respectively and further being oriented parallel thereto; an upper member removably attached to said lower member, said upper member having a plurality of lower surfaces coextensively and inversely positioned with said upper surfaces of said lower member such that a passageway is formed therebetween when said upper and lower members are joined together, said passageway surrounding a portion of the existing cart during operating conditions; a generally U-shaped extension having an open end removably and pivotally attached to said outside faces of said lower member; a curvilinear support plate removably attached to a closed end of said U-shaped extension; and means for adjustably positioning said U-shaped extension about the portion of existing cart; wherein said lower member further comprises a pair of coextensively shaped posts monolithically formed with said outside faces of said lower member, said posts having a hollow passageway formed therein and a centrally registered axis oriented parallel to a longitudinal axis of said lower member, said posts further having apertures formed in distal ends thereof respectively and oriented perpendicular to the longitudinal axis; wherein said open end of said U-shaped extension abuts directly about said posts such that said U-shaped extension freely articulates to a plurality of positions above and below the portion of the existing cart during operating conditions; wherein said upper member further comprises a plurality of curved flanges monolithically formed with outside faces of said upper member, said flanges having a vertically oriented groove formed therein and extending along an entire height of said upper member, said groove having an open face oriented toward the portion of the existing cart during operating conditions, said groove receiving and capturing said U-shaped extension when said U-shaped extension is biased upwardly.
