Electric toothbrush head
First Claim
1. A toothbrush comprising:
- a head having a planar front surface and a back surface;
a base member;
a support member fixed to the base member and having a plurality of holes extending therethrough;
a resilient cushion member disposed, at least in part, between the base member and the support member, the cushion member having a plurality of protrusions extending therefrom; and
a plurality of bristle tufts, each bristle tuft capable of engaging at least one protrusion;
wherein at least a first bristle tuft is resiliently coupled to the head and extending from the front surface and through a corresponding hole in the support member in a first protruding direction; and
at least a second bristle tuft resiliently coupled to the head and extending from the front surface and through a corresponding hole in the support member in a second protruding direction away from the first protruding direction,wherein applying a force to the first bristle tuft and/or the second bristle tuft causes the first bristle tuft and/or the second bristle tuft to deflect towards the back surface of the head.

Abstract
A head for an electric toothbrush includes a support member having a plurality of holes extending completely therethrough. A plurality of tufts of bristles each extends through one of the holes. A first brushing end of each tuft projects from a first side of the support member. Each tuft is prevented from being withdrawn from its hole when a tensile force is applied to the first end of each tuft along a long axis of the tuft. A resilient cushion is positioned adjacent a second side of the support member such that a second end of each tuft can contact the cushion. When a compressive force is applied to the first end of each tuft along the long axis of each tuft, each tuft can move in its hole in a first direction into the cushion. When the compressive force is removed the cushion causes each tuft to move in its hole in a second direction substantially opposite the first direction.

7. A toothbrush comprising:
-
a head having a front surface and a back surface; a base member; a support member fixed to the base member and having a plurality of holes extending therethrough; a resilient cushion member disposed, at least in part, between the base member and the support member, the cushion member having a plurality of protrusions extending therefrom; at least one first bristle tuft extending from the first surface and through a corresponding hole in the support member at a first angle, the first surface being a planar surface; and at least one second bristle tuft extending from the first surface and through a corresponding hole in the support member at a second angle, wherein the first angle and the second angle are different; wherein the first and second bristle tufts are capable of engaging the plurality of protrusions such that the first and second bristle tufts are resiliently coupled to the head whereby applying a force to the resiliently coupled bristle tuft causes the resiliently coupled bristle tuft to move toward the head. - View Dependent Claims (8, 9, 10, 11)
