ADJUSTABLE CURVATURE TOOTHBRUSH BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention pertains to toothbrushes. More particularly, this invention pertains to' adjustable curvature toothbrushes which comprise a flexible brush head which is adjustable to convex, concave, and straight configurations in order to conform the toothbrush to the 15 curvature of human teeth.
2. Description of the Prior Art
The configuration of human teeth requires that the ideal bristle contour for toothbrushes for brushing the labial or outside surfaces of teeth be concave and that the ideal bristle contour for brushing the lingual 25 or inside surfaces of teeth be convex. Conventional toothbrushes are generally of a fixed curvature or configuration or are adjustable into different configurations. Fixed configuration toothbrushes have limited effectiveness, and cannot properly clean teeth and 3 0 convertible toothbrushes are generally difficult to manipulate and are unreliable.
United States patent no. 4,712,267, issued to Cheng, discloses a convertible toothbrush comprising an 35 s-shaped elongated handle of shape-retaining material having curved end regions of opposite curvature, a flexible brush block containing bristles, and a means for mounting the flexible brush block on the handle for longitudinal movement along the length of the handle.
237951
The curved portions of the handle bend the flexible block and bristles into a concave or convex configuration which corresponds to the curved configuration of the handle.
United States patent no. 4,694,844, issued to Berl et al. . discloses a toothbrush comprising a handle and a hollow head supporting a plurality of tufts. The hollow head further comprises an elastically deformable element which urges the tufts toward a generally straight position. When pressure is applied to a tuft during the use of the toothbrush, the pressure causes the tips of the tufts to conform to the contours of a given group of teeth because the tufts are pushed into the hollow head to varying degrees against the restoring force of the elastically deformable element.
United States patent no. 4,691,405, issued to Reed, discloses a toothbrush comprising a handle and a base at the end of the handle consisting of two tabs containing bristles. The tabs pivot relative to the base so that the bristles mounted on the tabs deflect in order to conform to the varying tooth surfaces.
United States patent no. 4,524,478, issued to Ross, discloses a toothbrush consisting of two brush heads extending outwardly from a common elongated handle. The brush heads are connected to the handle by means of curved necks extending in parallel but opposing directions and at opposite and equal angles of forty-five degrees. Each brush head is designed to clean one-half of the teeth.
European Patent Publication no. EP206089 to
Sulit, discloses a toothbrush with two brush heads, one concave and one convex. The brush heads are either integral or slideable and are perpendicular at the opposite ends of their common handle. The brush head with a concave-shaped bristle surface is loncfe'r while the

brush head with a convex-shaped bristle surface is shorter.
United Kingdom published application no. 2178304 to Mina. discloses a toothbrush having a brushing surface which is set at an angle to the plane of the handle and is inclined or curved in a convex shape, as viewed in transverse cross-section. The angle of the brushing surface conforms to the tooth-gum junction.
While the above toothbrushes provide brush heads with some degree of curvature, none of the above toothbrushes is entirely satisfactory. Fixed configuration toothbrushes have limited effectiveness and 15 adjustable curvature toothbrushes are generally difficult to manipulate and are unreliable. Accordingly, it would be advantageous to provide an adjustable curvature toothbrush which can efficiently clean teeth and which is not awkward to use. The present invention provides... such 20 an improved adjustable curvature toothbrush.
