  • Patent number: 8032966
    Abstract: A hand-gripable presentation marker carrier is disclosed for holding and quickly accessing a plurality of different color presentation markers. The carrier includes a hand-gripable support element including a plurality of marker-tip receiving structures disposed along a surface of the hand-gripable support element, the surface of the hand-gripable support element supporting each of the marker-tip receiving structures. The carrier can also include an eraser housing for receiving an eraser assembly. The plurality of presentation markers are held perpendicularly with respect to the surface of the support element, and each marker-tip receiving structure is shaped so as to grip a marker at its tip-end and hold it to the common hand-gripable support element regardless of the orientation of the common hand-gripable support element. The eraser assembly is sized such that it fits snugly within the eraser housing, and can be inserted and removed from the eraser housing with convenient and comfortable force.

  • Patent number: 7895700
    Abstract: Disclosed is a cleaning device having a cleaning head to which a cleaning sheet is to be attached. The cleaning head has a pad whose bottom face functions as a cleaning part. The cleaning part has a recess, side contact parts on both sides of the recess and a rear contact part behind the recess. When a front portion of the cleaning head is pressed against a floor surface by a pushing force acting on the shaft, the recess prevents excessive frictional resistance. In addition, the cleaning sheet can be efficiently exploited because dirt can be collected also in the center of the cleaning part.

  • Patent number: 6574825
    Abstract: The invention concerns a cleaning device for casing components of electronic devices such as laptop computers, keyboards, monitors and such which are susceptible to dust. The device has a cuboidal block (10) made of a flexible material which on its underside, which is the surface of the block intended to contact the surface being cleaned, has a large number of incisions (14) which run crossways and form flexible fins (16) which can be deflected outward toward both sides. When the device is in use the fins spread and create slits (22) to collect dust. The incisions preferentially stretch over two thirds of the height of the block and run virtually parallel to its sides, so that the fins have a rectangular cross-section. The block is preferentially made of a soft foam.

  • 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: 5867856
    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) is received which is mounted so as to be rotary about a longitudinal axis (3) and is adapted to be driven in an oscillatory fashion. Further, the brush section (1) includes a bristle supporting structure (11) which is arranged so as to be rotary about a transverse axis (14) by means of a bearing pin (18) and is adapted to be set in a rotational motion (29) about said transverse axis (14) by means of a drive pin (24). The fixed connection between the bearing pin (18) and the shaft (7) has the added effect of causing the bristle supporting structure (11) to perform a pivotal motion (28) about the longitudinal axis (3). The rotational motion (29) of the bristle supporting structure (11) produces a cleaning action on a user's exposed tooth surfaces, whilst the pivotal motion (28) acts to accomplish an additional cleansing operation on the user's inter-proximal surfaces.

  • Patent number: 5651835
    Abstract: The disclosed model railroad car wheel cleaning device has a structural base, and mats sandwiching the opposite broad faces of the base with each mat having many pairs of elongated substantially parallel grooves formed therein. The grooves are laterally spaced apart to receive the wheel flanges when the wheels are positioned against the mat. The mat material is durable, resilient, elastic and has minute open cells, capable of holding liquid solvent effective for removing particulate buildups on the car wheels. The car wheels are cleaned by wetting one of the mats with solvent, positioning the wheels against this mat with the wheel flanges in paired grooves, and rolling the railroad car along the mat in line with the grooves operable to wet end abrade the wheels for removing particulate buildups therefrom. The railroad car can further be positioned against and rolled along the second mat with the wheel flanges seated in paired grooves operable to dry and buff the wheels.

  • Patent number: 5617603
    Abstract: The present invention provides a staggered swing brush head assembly of an electric toothbrush. There are two swing bodies adjoin in the head part of the toothbrush by a swing bar. They can wobble to the opposite direction as the rear swing body is driven to swing by an eccentric cam of a drive rod. By this means the vibration force of the electric toothbrush can be eliminated to the less, and the action of the brush hair is in accord with the correct method of cleaning tooth. On the other hand, the rotating drive rod with the threaded blade drives the water and the powder infiltrating into the shell trunks out through the slots under the centrifugal effect.

  • Patent number: 5504959
    Abstract: A brush provided on an end surface of a handle is equipped with a drive device capable of producing a reciprocating rectilinear motion in the direction of a handle axis and a reciprocating motion about the handle axis, while also producing a reciprocating motion about an axis in the direction of brush projection. The brush moves in a combination of the reciprocating rectilinear motion in the direction of the handle axis, the reciprocating motion about the handle axis, and the reciprocating motion about the axis in the direction of brush projection, and therefore scrub area increases, by virtue of the motion of the brush, the brush does not become trapped between teeth, and cleaning of the entire tooth surface is possible.

    Abstract: An automatic toothbrush to optimally clean at least two sides of a tooth or a row of teeth comprising a cleaning head with a substantially U-shaped support to which are mounted clusters of bristles. The clusters of bristles are mounted on self-positioning pivoting levers of the U-shaped support in order to clean even little accessible tooth locations. Using at least one mechanical and/or electromagnetic drive means, control is made possible of a phase-shifted, impulsive motion of the support relative to the automatic toothbrush and of the pivoting levers with the cleaning bristles relative to the support to implement a cleaning or wiping action by the clusters of bristles from the gum to the tooth crown while, in the opposite direction, the motion takes place with at least reduced pressure applied to the teeth.

  • Patent number: 5341535
    Abstract: A window scraper and method are provided wherein a scraping brush has filaments and wherein the tips of the filaments are moved linearly across the work surface as the brush rotates. Preferably, the brush has brass filaments trimmed to a point, and the brush drive mechanism moves the brush in an oscillating arcuate path while cams and cam surfaces simultaneously cause the brush to move toward and away from the work surface to maintain the tip of the filaments in substantially the same plane at a constant distance and pressure relative to the work surface. A novel brush has filaments trimmed to a point, an axle of rotation and cams to engage cam surfaces. The device includes an oscillating drive mechanism, a slot to rotatably and slidingly receive the brush axle, and cam surfaces to engage the brush cams and cause the brush axle to slide in the slot, causing the brush to move toward and away from the work surface during portions of the rotating brush sweep.
