Abstract
A massaging apparatus includes a foam pad having top and bottom profiles and a composite volume VC of foam; and a vibrator coupled to the foam pad for vibrating the pad. The pad is formed including a first foam phase defining the bottom profile and having a first phase volume V1 being not less than approximately 50 percent of the volume VC, and a second foam phase defining at least a portion of the top profile and having a second phase volume V2 being a pin member projecting from proximate the side surface, through the solid portion of the threaded insert, and engaging the first structural member on opposite sides of the cavity, the pin member securing the threaded insert in the cavity. A method for forming the pad includes preparing a liquidic slow-curing first foam formulation; feeding the first foam formulation into a mold; preparing a liquidic faster-curing second foam formulation; after a first period of time following the step of feeding the first foam formulation, feeding the second foam formulation into the mold onto the first formulation; curing the formulations; removing the cured foam article from the mold; forming a cavity in the article being a foam pad; and assembling a vibratory transducer into the cavity to form a vibratory massaging pad.
