Abstract

Abstract A lice comb comprises a handle and a resiliently flexible elongated member having the end portions thereof connected to the handle and teeth mounted outwardly from the member and extending in the same plane as the handle. A manually movable cam member is mounted on the handle and contacts the member opposite the side holding the teeth and intermediate of the end portions to flex the member outwardly relative to the handle between a minimum flexure position wherein the teeth have a minimum spacing therebetween and a maximum flexure position wherein the teeth have a maximum spacing therebetween. As a result the comb can be used for different textures of hair and the teeth can be easily cleaned.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 219 words
A lice comb comprising: a handle; a resiliently flexible elongated member; a plurality of closely spaced comb teeth mounted in a row on a first side of the member and extending outwardly therefrom and wherein the teeth terminate in free ends; means connecting end portions of the member to the handle to dispose the free ends of the teeth away from the handle; and manually movable means mounted on the handle for contacting the member on a second side opposite said first side and intermediate of the end portions thereof to flex the member outwardly relative to the handle between a minimum flexure position wherein the teeth have a minimum spacing therebetween and a maximum flexure position wherein the teeth have a maximum spacing therebetween and whereby the comb can be used for different textures of hair and the teeth can be easily cleaned, wherein the manually movable means has means mounting same for movement into any one of a plurality of positions each corresponding to a different amount of flexure by the member and thereby a different spacing between the teeth comprising a cam member rotatably mounted on the handle and having a cam surface for contacting said second side of the flexible member and a lever connected to the cam and manually movable to rotate the cam.
Claim 2
Dependent Claim 219 words
A lice comb comprising: a handle; a resiliently flexible elongated member; a plurality of closely spaced comb teeth mounted in a row on a first side of the member and extending outwardly therefrom and wherein the teeth terminate in free ends; means connecting end portions of the member to the handle to dispose the free ends of the teeth away from the handle; and manually movable means mounted on the handle for contacting the member on a second side opposite said first side and intermediate of the end portions thereof to flex the member outwardly relative to the handle between a minimum flexure position wherein the teeth have a minimum spacing therebetween and a maximum flexure position wherein the teeth have a maximum spacing therebetween and whereby the comb can be used for different textures of hair and the teeth can be easily cleaned, wherein the manually movable means has means mounting same for movement into any one of a plurality of positions each corresponding to a different amount of flexure by the member and thereby a different spacing between the teeth comprising a cam member rotatably mounted on the handle and having a cam surface for contacting said second side of the flexible member and a lever connected to the cam and manually movable to rotate the cam.
