Abstract: The present invention is concerned with a device for converting a rotating input motion into a modified output motion. The device has a magnetic coupler including a secondary magnet, a motion output member, and one, or at least a first, primary magnet. The magnetic or polarity profile of the first primary magnet and the magnetic or polarity profile of the secondary magnet are different. The device is configured such that rotating movement of the first primary magnet translates to a combination of rotating and oscillating movement of the motion output member.
Abstract: The invention relates to a mechanism for driving the head of an electric toothbrush. The mechanism includes a cam 20 rotatably driven by a motor 10 and an elongate transfer mechanism 30 having a receiver 40 for receiving the cam at one end and a mechanism for transferring oscillatory motion to a toothbrush head 60 at the other end thereof. Cam 20 has a projecting head 23 which is received in a substantially rectangular aperture 41 of the receiver 40. The long side of the substantially rectangular aperture has a length equal to or greater than the diameter of the circular motion of the projecting head 23, the short side has a length less than the long side of the rectangular aperture. Thus, in use, circular motion of the projecting head of the cam is converted into oscillatory pivoting motion of the transfer member 30 by action of the projecting head 23 against the short sides of the substantially rectangular aperture 41.
Abstract: A brush for cleaning purposes comprises an elongate block (8), a spigot (10) extending laterally from the block (8), a handle (2) secured to the spigot (10), a plurality of outwardly-extending bristles (6) secured to the block (8), including bristles (6) on a region of block (8) adjacent the spigot, which bristles (6) extend in the direction of the spigot (10) towards the handle (2).
Abstract: A connector for securing a handle to a utensil comprises a male part (14) having a threaded portion (16) adjacent the free end thereof which joins a shaft portion (18) of greater diameter than the threaded portion (16), a female socket part (10) with a complimentary internal screw thread, and a support collar (26) jointed to the socket (10) to overlie the socket (10) and defining an opening (24) for receiving the male part (14) through which the shaft portion (18) extends and which tightly engages the shaft portion (18) when the male and female parts are engaged.
Abstract: A handle for a hand-held or operated object or appliance comprises a main body (4) of a rigid material and a separate moulding insert (14) which can be fitted on the main body and having a raised pattern or shape (“HO”) including at least one element thereon of closed form, the insert (14) defining therein or defining with the main body a bore or bores (18, 24) which communicate with the interior of the element of closed form, through which a soft plastics material such as an elastomer being overmoulded on the handle can flow.
