  • Patent number: 7832108
    Abstract: A pencil sharpener includes a housing having an inner cavity for receiving at least a portion of a pencil therein. The pencil includes a center portion and an outer portion generally coaxial with the center portion. A sharpener is longitudinally slidable within the inner cavity. A mechanism provides a linear force to the sharpener to move the sharpener between open and closed ends of the housing. The linear force mechanism is disposed between the sharpener and the closed end of the housing. The engagement of the pencil and housing during sharpening of the pencil produces shavings from the center and outer portions of the pencil that are retained within the inner cavity. A combined longitudinal length of the housing and pencil in an engaged configuration remains approximately constant as the pencil decreases in length from use and/or sharpening.

  • Patent number: 7225547
    Abstract: A compact sharpener (1) for a pencil (S), the sharpener being cost-effective to realize and being particularly suitable for sharpening a cosmetic pencil in particular, comprises a sharpener body (2) and a shaving blade (3) fastened thereon. The sharpener body (2), in turn, comprises a guide sleeve (4) and a blade holder (5) integrally formed on the guide sleeve (4), the guide sleeve (4) having a bore (6) which defines a pencil-guiding channel (7) and has an introduction end (8) and an outlet end (9) for the pencil (S), and the blade holder (5) having a bearing surface (15) which is positioned obliquely in relation to the axis (11) of the pencil-guiding channel (7), projects axially beyond the outlet end (9) of the guide sleeve (4) and is intended for positioning the shaving blade (3).

  • Patent number: 7036231
    Abstract: A sharpener includes a sharpener body, a guide collar and a shaving blade. The guide collar has an oval bore defining a pencil-guiding channel and is mounted on the sharpener body such that it can be rotated essentially about the axis of the pencil-guiding channel. The shaving blade is fastened on a blade holder of the sharpener body to be positioned axially offset in relation to the guide collar and obliquely in relation to the axis of the pencil-guiding channel. A concave guide contour, into which the shaving blade projects by way of a cutting edge is formed on an inner surface of the blade holder adjacent to the pencil-guiding channel. When the pencil positioned in the pencil-guiding channel is rotated in relation to the sharpener body, the axis of the pencil-guiding channel is guided on an essentially oval path in relation to the cutting edge.

  • Patent number: 6732437
    Abstract: A sharpener for pencils with a soft lead with a sharpener housing has a conical sharpener channel, a sharpening knife which is fastened at the fastener housing and which is set tangentially to the sharpener channel. A shape-cutting knife, which can be swiveled into the sharpener channel, is provided with a manually actuated lever and with an arc-shaped, curved cutting edge for the selective shaping of the front end section of the lead. The sharpener is constructed as a double sharpener with individual sharpeners for pencils of different diameters placed opposite to one another in a common housing and the shape-cutting knives can be swiveled alternatively upward against the lead in the respective individual sharpener about a common axis, which is disposed at the common front end of the sharpener channels which are open in the upward and downward directions in this region.

  • Patent number: 6574875
    Abstract: The present invention is for an improved pencil sharpener that is slidingly disposed about a pencil. The pencil sharpener comprises a cutting surface, a first arm pivotally mounted or connected with respect to a second arm, and a pencil receiving variable-sized aperture formed through the interior of the first arm and the second arm. The variable-sized aperture preferably alters in size and/or shape depending on the pivotal position of the first arm with respect to the second arm. The pencil receiving variable-sized aperture preferably forms a substantially conical channel when the first arm and the second arm are compressed inwardly for sharpening the pencil. In another position of the arms, the variable sized aperture permits the pencil to slide through the pencil sharpener.

  • Patent number: 6279238
    Abstract: A carpenter's pencil sharpener for sharpening carpenter's pencils is disclosed. The pencil sharpener comprises a housing having both a vertically oriented oval shaped bore and a horizontally oriented oval shaped bore extending therethrough. The oval shapes of the bores corresponds to the profile of a carpenter's pencil. The bores are parallel and aligned with respect to each other. A cutting edge resiliently extends at an angle into the path of the bores. The angle of the cutting edge being adapted to allow a carpenter's pencil to be slid within said bore when inserted therein but whittling a carpenter's pencil when withdrawn therefrom.

  • Patent number: 5647138
    Abstract: The present invention provides a cap sharpener for clutch-type pencil, in which a blind end divides a cylinder from the cap, and the blind end has a through-hole at the center portion interconnecting the cylinder. The cylinder has a blade mounted on the top inner portion slantly and engaging with a lead which extends through the through-hole of the blind end. Two opposite resilient trips are formed in the inner wall of the cap with two granular projections extending inwardly from the trips, respectively. When turning the cap and a pencil being capped with the cap in an opposite directions, the cap will hold the pencil shaft still for the blade in the cylinder to cut the lead accurately. Additionally, the cylinder can be separated from the cap, and holding the blade in a slanting angle in a hollow body, and connected to the blind end of the cap by means of female and male joining faces. The hollow space of the cylinder, furthermore, can be used for collecting the lead chip powder.
