A longitudinal groove is defined underneath each of the send-cylindrical grooves, and equal-length side brushes, which are affixed to an inner surface of a lid, are respectively positioned in the longitudinal grooves. Two grooves are arranged adjacent to each end of the semi-cylindrical grooves, which provide for a shaft affixed to each end of a roller to dispose therein. The brushes and the rollers form the eraser, which are enclosed within a closed chamber between the lid and the two semi-cylindrical grooves. When erasing chalk dust from a blackboard, the chalk dust sticks to the rollers and is carried to the side brushes. The side brushes then wipes the dust, which falls into the closed chamber.

  • Patent number: 5996157
    Abstract: A hand held toothbrush with multiple levels of bristles on a rotary pad. When the user manually pushes the brush, there is a force created which propels the bristles to catch the irregular surface of the teeth, gaps, and pockets, causing the rotary pad to turn. The bristle's pattern is designed specially to improve the rotary pad to circular more effectively. The advantage of this invention is that even though the user operates the toothbrush in left and right movement, the bristles on rotary pad, converts left and right motion into circular motion.

  • Patent number: 5974615
    Abstract: An electric toothbrush (1) is described which incorporates a handle (2) and a brush attachment (3). The handle (2) houses an electric motor (8). Protruding from the handle (2) is a shaft (20), which is coupled to the electric motor (8). The brush attachment (3) can be mounted on the handle (2). The brush attachment (3) supports a bristle head (26) which can be coupled to the shaft (20), and from which protrude a multiplicity of bristles (4). In the operating mode, the bristle head (26) describes a rotary motion (49) and a stroke motion (50), with the frequency of the stroke movement (50) being higher, and preferably substantially higher, than the frequency of the rotary movement (49.) The stroke movement (50) provides a poking action of the bristles (4), which serves to loosen plaque from dental surfaces. The rotary movement (49) serves to wipe away plaque loosened from the dental surfaces.

  • Patent number: 5974613
    Abstract: The invention is directed to a brush section (1) for an electric toothbrush which includes a mounting tube (2) in which a shaft (7) rotatably mounted about a longitudinal axis (3) and driveable in an oscillatory or rotary fashion is received. Further, the brush section (1) includes a bristle carrier (11) which is pivotally mounted on an angled end (19) of the shaft (7) configured as crankshaft and which, in operation of the electric toothbrush, is set in a rotary motion (26) about the transverse axis (14) by a pin (23). The angle (20) formed by the longitudinal axis (3) and the angled end (19) of the shaft (7) serves the added function of causing the bristle carrier (11) to perform a pivotal motion (27) about an axis (28).

  • Patent number: 5943723
    Abstract: The invention is directed to an electric toothbrush (1) in which a timing element (13) is provided whose purpose it is to indicate to a user the end of at least one cleaning period when the electric toothbrush (1) is activated. Still further, means (12) coupled to the timing element (13) are provided to enable the user to trigger the beginning (T4) of the cleaning period (PZD2). The effect thereby achieved is that the end (T2) of a cleaning period (PZD1) does not automatically start the beginning (T4) of the next cleaning period (PZD2), but that this particular beginning (T4) of the next cleaning period (PZD2) is freely selectable by the user.

  • Patent number: 5930858
    Abstract: The invention is directed to a method and an electric toothbrush which includes a timing circuit (7) serving to signal to a user the expiration of a first period (T1), that is, the expiration of the optimum brushing time, following activation of the electric toothbrush. Further, an On/Off switching device (4) is provided which is controllable by the timing circuit (7) and by means of which the electric toothbrush can be turned on and off. The timing circuit (7) controls the On/Off switching go0 device (4) such that following expiration of the first period (T1) the electric toothbrush is turned on and off repeatedly within a second period (T2). As a result, the user of the electric toothbrush "senses" directly the end of the first period (T1), that is, the end of the optimum brushing time, from the variation in the operating mode of the electric toothbrush.
