Right angle tooth brush

Abstract

A polyaxial toothbrush constructed to provide a brush portion with a plurality of axes of pivotal movement relative to a handle which can assume a straight or intermittently-angled shape position is described. The toothbrush is formed by interconnecting a brush portion and a head portions by a universal joint to define a polyaxial joint. The universal joint includes a substantially spherical end and a substantially spherical appendage extending outwardly end sized to cooperate with the spherical cavity. Such construction and arrangement provides universal movement between the brush and handle portions. The toothbrush further has at least one resilient member extending between the brush portion and handle portion of the invention, providing resistance to the pivoting brush portion with respect to the handle portion.

1 . A polyaxial toothbrush comprising:
 a brush portion, said brush portion having a first end and second end, an outer surface and a first longitudinal centerline, said first end of said brush portion having a plurality of bristles extending outwardly with respect to said outer surface, said second end including a first portion of a polyaxial joint;   a handle portion, said handle portion having a first end and a second end, an outer surface and a second longitudinal centerline, said outer surface defining a grip, said first end including a second portion of said polyaxial joint, said second portion of said polyaxial joint being constructed and arranged to cooperate with said first portion of said polyaxial joint to define a polyaxial joint constructed and arranged to provide said brush portion with at least two axes of pivotal movement with respect to said handle portion.   
   
   
       2 . The polyaxial toothbrush of  claim 1  including at least one resilient member extending between said second end of said brush portion and said first end of said handle portion, said at least one resilient member being constructed and arranged to provide resistance to pivoting said brush portion with respect to said handle portion. 
   
   
       3 . The polyaxial toothbrush of  claim 2  wherein said at least one resilient member is a sleeve constructed and arranged to engage said outer surface of said brush portion and said handle portion. 
   
   
       4 . The polyaxial toothbrush of  claim 1  wherein said first portion of a polyaxial joint includes a substantially spherical cavity aligned along said first longitudinal axis and said second portion of a polyaxial joint includes a substantially spherical appendage extending outwardly from said first end of said handle portion and aligned substantially along said second longitudinal axis, said spherical appendage sized to cooperate with said spherical cavity to provide universal movement between said brush portion and said handle portion. 
   
   
       5 . The polyaxial toothbrush of  claim 4  including at least one resilient member extending between said second end of said brush portion and said first end of said handle portion, said at least one resilient member being constructed and arranged to provide resistance to pivoting said brush portion with respect to said handle portion. 
   
   
       6 . The polyaxial toothbrush of  claim 5  wherein said at least one resilient member is a sleeve constructed and arranged to engage said outer surface of said brush portion and said handle portion. 
   
   
       7 . The polyaxial toothbrush of  claim 6  wherein said brush portion includes an enlarged, depressed area positioned above the polyaxial joint and proximal to said first end of said brush portion.
