Title:
ROTATABLE TOOTH BRUSH
Document Type and Number:
WIPO Patent Application WO/2006/123435
Kind Code:
A1
Abstract:
A rotatable tooth brush, wherein the shaft of the portion of a power point (10) is formed in a thin and smooth recessed and curved shape to minimize a friction at the power point by using the principle of leverage in which the portion thereof in contact with teeth and gum is used as a point of application (11) and the portion thereof held by a thumb and an index is used as the power point so that the bristle tips thereof touch the teeth and the pockets of the gum at the right angle to each other. The crossed portion of the tip part of the shank of the tooth brush with a palm is formed in an easily movable shape with less friction by using, as a pivot (9), the crossed point of the tip portion of the shank with the instep of a hand at a web part between the thumb and the index. Since a bulge is formed on the opposite side of the diagonal line of the bristles of the brush and an angle for easy rotation is formed between the shank and a tooth brush head so that the tooth brush can rapidly brought into contact with the teeth and the gum at the right angle, a moment of motion can be easily provided. Thus, since the brush is freely rotated by the movement of bristle tips and stabilized when it collides with an object, the brush can always touch the object at the right angle.
