Abstract: A foldable support base for a foldable furniture with a flexible user support platform, in which a support frame has two side frame members, each pivotally connected to a load pivot joint along a load member with a load section extending beyond the load pivot joint which is pivotable about the first load pivot joint towards a center of the support frame. The load sections of the load members are configured for removably attaching a flexible user support platform therebetween. A load on the flexible user support platform results in a force component pulling on the load sections of the load members to cause the load members to pivot about the respective load pivot joints in a direction towards the flexible user support platform, thereby biasing to keep the side frame members to be spaced apart to maintain the support base in an extended configuration.

Abstract: A smart trash can having a housing with a front housing door pivotable to tilt to a tilted open position. A bucket is attached to the housing door to tilt along with tilting of the housing door. A trash bag liner cartridge is supported below a housing lid within a crown of the housing. The liner cartridge stores a supply of liner material for trash bag replacements. A bag sealing and cutting mechanism seals a top opening of a filled trash bag and separates the liner material supplied from the liner cartridge upon tilting the housing door to the tilted open position, and seals an open bottom end of the liner material supplied from the liner cartridge. A bag relining mechanism lines the interior walls of the bucket with the liner material upon removal of the filled trash bag and closure of the housing door from its tilted open position.
