Drive mechanism for interproximal flossing device

Abstract

An interproximal flossing device including a link member that isolates lateral from vertical rotational movement to transfer only translatory arcuate movement. This is done by the combination of a hinge and pivot structure. A tip attachment structure is also included for secure placement of the tip on the link member, and allows easy removal and replacement. A tip member removal structure is also included to allow for easy removal of the tip member from the link member.

We claim:  
     
         1 . A structure for removing a tip member from a link member of an interproximal flosser, said structure comprising: 
 a slot for receiving the tip member, said slot having side walls that converge along the length of the slot to engage and deform the tip member as the tip member is moved along the slot.    
     
     
         2 . The structure for removing a tip member in  claim 1 , said structure further comprising: 
 a ramp surface that contacts said tip member as the tip member is moved horizontally along said slot thereby causing the tip member to eject vertically from said link member.    
     
     
         3 . The structure for removing a tip member in  claim 1 , said structure further comprising: 
 a lower slot surface that engages a key feature in said tip member thereby restricting the orientation of said tip member within said slot to ensure said tip cap will properly deform when slid along said slot.
