Definitions

  • the invention relates to a writing or drawing device according to the preamble of claim 1.
  • Writing and drawing pens which are often referred to as "felt pens" in the broadest sense and essentially of a laiigreckreckten sleeve-like pen body, provided at one end of the stiff body writing and drawing tip and a writing or drawing tip with a write - or drawing fluid, for example ink supply reservoir inside the pen body exist.
  • the drawing or writing tip is made of a porous, but nevertheless sufficiently hard material, for example of a porous plastic or composite material.
  • a pen of this kind is e.g. available under the brand name "edding" on the market.
  • a disadvantage of such writing and crayons is, inter alia, that they dry out easily, and that is when the writing and drawing tip having end of the pin is not properly closed when not in use by attaching a cap, but in many cases, either for convenience or but it does not happen because the cap has been lost.
  • a writing and / or drawing device with the features of the preamble of claim 1 is known ( DE-A-43 05 082 ).
  • the well-known, _not trained as felt or fiber pen device consists of a cylindrical housing with a frusto-conical tip. Within the housing is a cylindrical body made of a ductile material having a writing tip extending from the frusto-conical tip of the housing.
  • the writing and / or drawing device also has to extend and retract the write and / or Character tip from the conical tip of the cylindrical housing between a position of use and a non-use position a pressure mechanism.
  • a closure which consists of at least two wing-like closure elements and forms a shelter in which the writing and / or drawing tip is received in the non-use position sealed to the outside.
  • the closure elements are moved apart while opening a closure opening by the writing and / or drawing tip.
  • pressure or zugetti By acting on the outer surface of the closure elements pressure or zugetti these are biased in their closed position.
  • closure syringe for writing instruments DE-A-15 61 830
  • a closure syringe for writing instruments DE-A-15 61 830
  • a closing spring which encloses the closure on its outer surface, thereby forming a shelter for receiving a writing and drawing tip in its inoperative position.
  • a writing and / or drawing device US-A-4,218,154 having a closing body made of an elastic material and a mine axially displaceable in the housing between a non-use position and a use position, forming a writing and / or drawing tip.
  • a closing body made of an elastic material and a mine axially displaceable in the housing between a non-use position and a use position, forming a writing and / or drawing tip.
  • the writing and / or drawing tip in e i is nem outwardly closed protection space of the likewise axially displaceable in the housing closure body, which protrudes in this state with a conically tapered closure body end of the housing.

  • the shutter is opened by moving apart of the closure elements.
  • non-use state in the context of the invention is that state in which the pin (fiber pin) in the outer housing or in the protective sleeve is moved back so that the writing and / or tip of the pen in the closed by the closure Outside enclosed shelter is included and thus the pen or its writing and / or tip is protected against drying out.
  • position of use in the context of the invention means the position of the pin within the outer housing, in which the writing and / or marking tip projects outwardly through the open closure or through the closure opening formed by the opened closure.
