Abstract
A pencil sharpener has at least two sharpener units, each with a sharpener body and a shaving blade. The sharpener bodies of adjacent sharpener units being connected integrally via film strips acting as a predetermined bending point and/or predetermined separating point. In a second variant, the pencil sharpener has a sharpener body and a shaving blade fastened thereon. The sharpener body has a guide sleeve with a bore defining a pencil-guiding channel for a pencil to be sharpened, and at least one flat supporting wing which projects approximately radially in cross section from the guide sleeve. In an end region of the supporting wing a functional element is provided for protecting or for working on the tip of the pencil.
Claims15
A pencil sharpener, comprising:
- at least one sharpener body formed with at least one film strip defining a predetermined bending or separating point configured to enable at least one of the following:
- at least one part of said sharpener body can be bent;
- at least one part of said sharpener body can be detached;
- one sharpener body can be bent relative to another said sharpener body;
- one sharpener body can be detached from another said sharpener body;
- wherein said at least one sharpener body is at least two sharpener units each with a sharpener body and a shaving blade fastened thereon, and said sharpener bodies of adjoining said sharpener units are integrally connected via a film strip defining a predetermined bending point and/or predetermined separating point.
A pencil sharpener, comprising:
- at least one sharpener body formed with at least one film strip defining a predetermined bending or separating point configured to enable at least one of the following:
- at least one part of said sharpener body can be bent;
- at least one part of said sharpener body can be detached;
- one sharpener body can be bent relative to another said sharpener body;
- one sharpener body can be detached from another said sharpener body;
- a shaving blade fastened to said sharpener body, said sharpener body including a guide sleeve with a bore defining a pencil-guiding channel for receiving a pencil to be sharpened, and at least one flat supporting wing projecting substantially radially in cross section from said guide sleeve;
- said supporting wing having an end region, directed away from said guide sleeve, with a functional element for protecting or for working on a tip of the pencil to be sharpened, and wherein said or each said supporting wing is bendable along a film strip defining a predetermined bending point or predetermined separating point, and said functional element is movable away from a position in which said functional element engages with said pencil-guiding channel.
A pencil sharpener, comprising a plurality of interlinked sharpener bodies formed with at least one film strip defining a predetermined bending or separating point enabling one of said sharpener bodies to be bent relative to another of said sharpener bodies or detached and separated from another of said sharpener bodies, a plurality of sharpener units each including a a respective one of said sharpener bodies and having a shaving blade fastened thereon, and wherein said sharpener bodies of adjacent said sharpener units are integrally connected to one another via a film strip defining a predetermined bending point and/or predetermined separating point.
