Brushes for personal hygiene purposes
First Claim
1. A brush for personal hygiene purposes comprising an elongated housing, a rotatably mounted brush head supported on the housing, a connection member for connection to a linear reciprocal drive means providing drive in a direction generally parallel to the length of the housing, and a flexible member connected between the connection member and the head for converting linear reciprocal motion of the connection member to rotational motion of the head, the flexible member being biased in a direction away from the direction of the linear reciprocal motion of the connection member.

Abstract
A toothbrush is disclosed which comprises a rotatably mounted toothbrush head, 100, a connection member, 150, for connection to a linear reciprocal drive means contained in hand-held casing and a flexible member, 160, formed preferably from steel wire or ribbon disposed between the connection member, 150, and the head, 100, and for converting linear reciprocal motion of the connection member to rotational motion of the head.

15. A brush for personal hygiene purposes comprising:
-
a main body; a detachable head part operably connected to said main body, having a rotatably mounted brush head; a driven member connected to a linear reciprocal drive means in said main body; a connecting member connected to the brush head to transmit reciprocal drive to the brush head; and coupling means provided on said driven member, and on said connecting member to provide a releasable coupling therebetween, comprising a pair of freely extending opposed legs extending from an end of one of the connecting member and driven member, said legs having inwardly directed fingers, and a pair of grooves formed in opposite sides of the other of the connecting member and driven member within which the fingers are engageable when the head part is in a first orientation relative to the main body, the coupling means being adapted to allow said members to be detached when in a second orientation in which said head part is rotated relative to the main body. - View Dependent Claims (16, 17, 18, 19, 20)

21. A brush for personal hygiene purposes comprising:
-
a main body; a detachable head part operably connected to said main body, having a rotatably mounted brush head; a driven member connected to a linear reciprocal drive means in said main body; a connecting member connected to the brush head to transmit reciprocal drive to the brush head; coupling means provided on said driven member and on said connecting member to provide a releasable coupling therebetween, said coupling means being adapted to provide coupling between said members when the head part is in a first orientation relative to the main body part and to allow said members to be detached when in a second orientation in which said head part is rotated relative to the main body; engagement means comprising an axial plug formed on the main body, for receipt in a pocket like end of the head part, the plug being formed with at least one outwardly directed locking lug, and the head part being formed with a lug-receiving groove having an axial portion to allow a push-fit of the head part onto the main body, and a circumferential portion defining internally a shoulder behind which the lug engages on rotation of the head part to the first orientation in which the head part is prevented from axial release.

22. A brush for personal hygiene purposes comprising:
-
main body; detachable head part operably connected to said main body, having a rotatably mounted brush head; a driven member connected to a linear reciprocal drive means in said main body; a connecting member connected to the brush head to transmit reciprocal drive to the brush head; coupling means provided on said driven member and on said connecting member to provide a releasable coupling therebetween, said coupling means being adapted to provide coupling between said members when the head part is in a first orientation relative to the main body part and to allow the said members to be detached when in a second orientation in which said head part is rotated relative to the main body; one of the driven member and connecting member being formed at its coupling end with a tapering surface narrowing towards a locating pin at the extremity thereof, the other having a locating socket into which the pin fits to couple said driven member to said connecting member.
