Modular floor machine

Abstract

A floor machine configured to couple with a variety of attachments is provided. For example, the floor machine may be selectively coupled with a variety of rotary attachments in various sizes. When the floor machine is coupled with a rotary attachment, an electric motor on the floor machine may engage with the rotary attachment to provide rotational power. In addition, the floor machine may be selectively coupled with a variety of planetary attachments. When a planetary attachment is coupled to the floor machine, the electric motor may provide rotational power to the body of the planetary attachment. In addition, a planetary adapter may engage with the planetary attachment to cause planet assemblies to rotate on the body.

What is claimed is: 
     
         1 . A modular floor machine comprising:
 a base;   a rotary adaptor removably coupled to the base and defining an interior space; and   a rotary attachment rotatably coupled to the base in the interior space.   
     
     
         2 . The modular floor machine of  claim 1 , wherein a perimeter of the base abuts an upper surface of the rotary adaptor. 
     
     
         3 . The modular floor machine of  claim 1 , wherein a transmission of the base extends through an opening defined in the rotary adaptor. 
     
     
         4 . The modular floor machine of  claim 1 , wherein the rotary attachment is coupled to a transmission of the base. 
     
     
         5 . The modular floor machine of  claim 4 , wherein a protrusion of the transmission engages a groove defined in the rotary attachment. 
     
     
         6 . The modular floor machine of  claim 4 , wherein the transmission engages a collar of the rotary attachment. 
     
     
         7 . The modular floor machine of  claim 1 , wherein a lug of the base secures the rotary attachment to the base. 
     
     
         8 . The modular floor machine of  claim 7 , wherein the lug extends through a keyhole opening defined in the base. 
     
     
         9 . The modular floor machine of  claim 7 , wherein the lug engages the rotary attachment via one or more of an interference fit, a friction fit, and a clip of the rotary attachment. 
     
     
         10 . The modular floor machine of  claim 1 , wherein the rotary attachment is wider than the base. 
     
     
         11 . The modular floor machine of  claim 1 , wherein the rotary adaptor includes a ring gear and the rotary attachment includes a planet gear enmeshed with the ring gear. 
     
     
         12 . The modular floor machine of  claim 11 , wherein a bottom surface is coupled to the planet gear. 
     
     
         13 . The modular floor machine of  claim 11 , wherein a body of the rotary adaptor is coupled to the base and rotatably supports the planet gear. 
     
     
         14 . The modular floor machine of  claim 11 , wherein the body includes a collar extending from a planet carrier. 
     
     
         15 . The modular floor machine of  claim 1 , wherein a transmission of the base extends beyond a perimeter of the base. 
     
     
         16 . A floor cleaner comprising:
 a rotary adaptor removably coupled to a base; and   a rotary attachment partially covered by the rotary adaptor and drivably coupled to the base.   
     
     
         17 . The floor cleaner of  claim 16 , wherein a ring gear of the rotary adaptor enmeshes a planet gear of the rotary attachment. 
     
     
         18 . The floor cleaner of  claim 16 , wherein a transmission of the base extends through the rotary adaptor and couples to the rotary attachment. 
     
     
         19 . A floor maintenance device comprising:
 a base having a perimeter and including an electric motor;   a rotary adaptor defining an interior space and abutting the perimeter; and   a rotary attachment drivably coupled to the electric motor within the interior space.   
     
     
         20 . The floor maintenance device of  claim 19 , wherein a transmission of the base extends through the rotary adaptor and couples to the rotary attachment.
