Abstract
An outer shell construction particularly suited for a ski boot and method for forming same is provided. The outer shell construction is formed by the steps of injection molding an outer shell, and securing a collapsible core to the inside of the boot to define a cavity between the boot and the collapsible core. The collapsible core includes a conduit therethrough. The outer shell construction is completed by introducing a cellular polymer in viscous form through the conduit into the space and curing same.
Claims7
A method for forming an outer shell construction for a boot comprising the steps of injection molding an outer shell, releasably securing a collapsible core to the inside of said outer shell molding and spaced therefrom to define a cavity between said outer shell and said collapsible core, said collapsible core including a conduit therethrough, introducing a cellular polymer in viscous form through said conduit into said cavity and curing said cellular polymer whereby said cured cellular polymer and outer shell molding define a boot outer shell construction.
A method for forming an outer shell construction for a boot comprising the steps of injection molding an outer shell, inserting a block having a first specific density into said outer shell, securing a collapsible core to the inside of said outer shell molding and spaced therefrom to define a cavity between said outer shell and said collapsible core, said collapsible core including a conduit therethrough, said block having said first specific density occupying a portion of said cavity, and introducing a cellular polymer in viscous form having a specific density higher than said first specific density through said conduit into said cavity.
A method for forming a outer shell construction for a boot comprising the steps of injection molding an outer shell, releasable securing a collapsible core to the inside of said outer shell molding and spaced therefrom to define a cavity between said outer shell and said collapsible core, introducing a cellular polymer in viscous form into said cavity, curing said cellular polymer and removing said collapsible core whereby said cured cellular polymer and outer shell molding define a boot outer shell construction.
