  • Patent number: 10603949
    Abstract: A pen for writing and/or drawing purposes, and having a shaft and a core which is arranged within the shaft and is axially adjustable in the longitudinal direction of the shaft between an active position and an inoperative position. The core is completely arranged within the shaft in the inoperative position and projects with an overhang from a front end of the shaft in the active position. An actuating element is provided which is movable perpendicularly to the longitudinal direction of the shaft between an active position and an inoperative position and which is operatively connected to the core via a connecting element in such a way that, during a movement of the actuating element perpendicularly to the longitudinal direction of the shaft between the inoperative position and the active position, the core is axially adjustable in the longitudinal direction of the shaft.

  • Patent number: 9364062
    Abstract: A case has a body formed of a lower shell and an upper shell pivotally connected to each other. The lower shell contains a plurality of compartments serving to receive objects. A plate, one side of which bears holding elements for writing implements, is mounted on the body in a manner such that it can pivot about a pivot axis running approximately parallel to the flat plane of the lower shell. The plate, in a first pivoted position, rests on the lower shell and covers at least some of the compartments thereof and, in a second pivoted position, is swung out of the lower shell.

  • Patent number: 9211758
    Abstract: A pencil has a pencil casing made of a sharpenable casing material and a core held in a central receiving bore in the casing material that extends in the longitudinal direction of the pencil. One or more optical fibers made of a sharpenable material is/are arranged in the pencil casing. The optical fiber or optical fibers extends in the longitudinal direction as well and are at least partially surrounded by the material of the pencil casing. A light entry surface of the at least one optical fiber is arranged at the rear end of the pencil casing such that a light source, which is present there, can be used to inject light to said light entry surface. The light exit surface of the optical fiber exits at the forward end of the pencil casing.

  • Patent number: 9060587
    Abstract: A pencil has a shaft with a rear portion and a front portion which bears an application element on its front end. The pencil further has a cap which has on its rear end facing the shaft an opening, by way of which it is placed onto the front portion in the non-use state of the pencil. Inside the cap is a receiving sleeve, which receives the application element and has on its rear end facing the shaft an insertion opening for the application element. The receiving sleeve is guided so as to be axially movable between a first end position and a second end position. The receiving sleeve is arranged fully inside the cap in the first end position and its rear end projects out of the opening of the cap with a projection in the second end position.
