  • Patent number: 8713755
    Abstract: An insert assembly for an applicator is built from two semi-cylindrical retention jaws connected by a living hinge. Each of the semi-cylindrical retention jaws has a plurality of stake pins, while the first semi-cylindrical retention jaw has a locator receptacle and the second semi-cylindrical retention jaw has a locator insert. An insert is placed between the two retention jaws, which then close to secure the insert between the retention jaws. The locator receptacle receives the locator insert from the second semi-cylindrical retention jaw, helping to align the two retention jaws. The plurality of stake pins impale the insert, holding it in place. In addition to being secured by the stake pins, the insert is supported by an interior ridge. The insert assembly can then be slid into a barrel sleeve, held in place by a press fit or by a removable mounting system, such as a lug mount.

  • Patent number: 7503716
    Abstract: A writing instrument includes an elongate body having opposed first and second ends, a longitudinal axis and a bore therein extending from the first end. A marking body, such as one having lead or a colored material, extends from the first end and is seated in the bore, while a connector is coupled to the second end. An eraser, such as a rubber eraser, is coupled to the connector and is configured to erase markings made by the marking body. The eraser includes a flat surface that is configured to prevent the writing instrument from rolling about the axis down an inclined surface contacting the elongate body. The flat surface may be oriented on a plane that is substantially parallel to the axis. The flat surface may also include a dimension perpendicular to the axis that is larger than another dimension of the elongate body which is also perpendicular to the axis.

  • Patent number: 6935799
    Abstract: In a stick-like object receiving member having safety precautions, which receives a stick-like object, a sufficient air passage is secured without exerting an influence on the size of the stick-like object or the receiving member. An eraser receiving member 16, which is the stick-like object receiving member, includes a cylindrical side portion 16b which engages with at least a part of the outer peripheral surface of an eraser 13, and surrounds at least a part of the outer peripheral surface of the eraser 13, and a bottom portion 16a which closes one end of the cylindrical side portion 16b. A slit 16e is formed in the cylindrical side portion 16b and bottom portion 16a so as to penetrate the cylindrical side portion 16b and bottom portion 16a in the axial direction, and the slit 16e serves as an air passage.

  • Publication number: 20030200990
    Abstract: A writing implement having a forward-positioned eraser, and method. The eraser circumscribes the shaft of the writing implement, and may have an annular or doughnut shape. The eraser may be affixed to the shaft portion, for example where used with a fixed-length writing implement such as a mechanical pencil or erasable pen. The eraser may, alternatively, be slidable along the shaft portion, which would make the eraser useable with a sharpenable pencil, the length of which will be changed as a result of sharpening.

  • Patent number: 4167347
    Abstract: A removable finger grip adaptable to a wide variety and size of writing instruments. The finger grip is an elongate resilient body having a triangular cross-sectional shape and a cylindrical bore coaxial with the longitudinal axis. In order to accommodate a wide variety of writing instruments, the cylindrical bore has a plurality of ribs or ridges along the entire length of the bore for gripping instruments smaller in size than the diameter of the bore. The triangular shape provides three planar surfaces for gripping the device when installed on a writing instrument and also provides a thin web of material in the planar gripping surfaces between them and the cylindrical bore at the center of the planar gripping surfaces. This thin web allows the finger grip to expand for accommodating writing instruments larger than the cylindrical bore. The resilience of the finger grip allows easy removal from one writing instrument for use with another.
