Toothbrush head and handle unit

An improved hairbrush suitable for use both in general brushing and in conjunction with an air dryer for blow drying and styling hair includes a rigid body having an elongated handle and an elongated brush block or base. The brush block has back and face portions and a body of bristles are mounted on and project from the face. The brush block has a pair of integrally formed air baffles extending one along each side edge portion thereof and projecting in outwardly diverging relation from the face of the block and in outwardly spaced relation to the brush bristles, with the brush block and baffles cooperating to form a concavity or channel for trapping and redirecting a stream of air directed into the hair from one side of the brush by a conventional blow dryer. The outwardly projecting wing-like baffles may also be employed as an aid in molding and shaping the coiffure.

Air baffled hairbrush

A toothbrush has an elongated handle and a brush head supported at one end of the handle for a limited pivotal movement between opposed arms of a yoke structure, i.e., by torsion bar support elements joining the support arms to opposed edges of the brush head. A further resilient element may be employed between the brush head and the proximal end of the handle to provide additional resistance to pivotal movement. Preferably the further resilient element is designed to have an increased spring constant as the brush head is pivoted progressively farther from its normal position in substantially coplanar relation with the handle and thus acts as an effective stop limiting maximum pivotal movement of the head. The base of the brush head which supports the brush bristles, the handle, yoke and resilient support elements may be integrally molded from a single mass of synthetic resin material and at least the resilient elements are preferably formed from polypropylene, or a polymeric material having substantially the same physical characteristics.
