Definitions

  • the invention relates to a ballpoint pen with a sleeve-shaped housing and an ink-filled writing cartridge, the writing tip of which can be brought into a writing position outside the housing and into a rest position inside the housing by moving the writing cartridge by means of a spring-loaded push button arranged on the end of the housing facing away from the writing tip is.
  • the ink-filled writing cartridge is usually guided and arranged within the ballpoint pen housing in such a way that the writing tip, at a first pressure exerted on the pushbutton, moves slightly out of the end of the housing facing away from the pushbutton occurs, whereupon the ballpoint pen can be used, while another push on the push button pulls the cartridge back into the housing.
  • Ballpoint pens of this type have proven themselves in principle, but there is a certain disadvantage in that it is not possible to shorten the overall length of the ballpoint pen in the non-use position, as is the case for some applications, for example in the case of ballpoint pens used in women Evening bags or the like are to be worn, is desired without reducing the effective length of the ballpoint pen in the use position. The latter is undesirable, however, because in this case writing itself becomes more difficult.
  • the invention has for its object to provide a ballpoint pen of the generic type, the total length in the non-use position is significantly smaller than in the use position, the cartridge in the non-use position arranged reliably inside the housing and on the other hand, securely and firmly stored in the housing in the writing position should be in order to have a stable writing instrument available during the writing process.
  • the writing cartridge is designed in the manner of a mechanical pencil lead as an essentially cylindrical falling body, on the peripheral wall of which the clamping jaws of a clamping pliers actuatable by the push button engage in a frictional manner.
  • the invention is based on the surprising finding that it is possible to create a ballpoint pen, the total length of which in the non-use position is practically only half of the total length in the use position, in which the writing cartridge according to the type known from case pencils in the case of lead refills by means of a pair of pliers is applied via the push button.
  • This ensures that the write cartridge is reliably accommodated and protected in the housing in the non-use position, while at the same time a secure, stable connection between the write cartridge and the housing is ensured in the use position, so that a faultless writing process is possible.
  • the ballpoint pen according to the invention takes up little space and can also be easily transported, for example, in handbags, but also in corresponding holders of notepads or the like.
  • the plastic peripheral wall of the falling body near the end of the falling body facing away from the writing tip is conically tapered in the direction of the falling body end, since this causes the clamping pliers to engage -The case body is still improved. This is due to the fact that, as a result of the conical design, when the writing pressure is exerted on the writing cartridge, the latter pushes more and more firmly into the clamping jaws of the clamping pliers, so that slipping of the writing cartridge within the housing during the writing process is practically impossible.
  • the drawing consisting of a single figure shows an exemplary embodiment of the ballpoint pen according to the invention in section.
  • the ballpoint pen according to the invention has a housing 8 in the exemplary embodiment shown, within which a drop body 10 is arranged, which contains the writing material, for example in the form of a conventional ballpoint refill, in its interior.
  • the peripheral wall 12 of the falling body 10 consists of plastic which is elastically deformable on the surface. In the non-use position shown in FIG.
  • clamping jaws 14 hold the drop body 10 firmly within the housing 8 by firmly contacting the cylindrical peripheral wall of the drop body 10 with their thread-like notches provided with a spring 17 an actuation of a push button 18, the end of the ballpoint pen shown on the left being held down, "falls” or slides the drop body 10 out of the housing 8 until a stop 19 on an inner annular projection of the housing 8, such as he can be seen in the drawing on the left, comes to the plant.
  • the clamping pliers 20 with their clamping jaws 14 lie firmly against the cylindrical peripheral wall of the falling body 10, the plastic material of the falling body 10 being elastically deformed on the surface, so that in cooperation with the thread-like configuration of the contact surfaces 16 of the clamping jaws 14 The falling body 10 slides back during the writing process is reliably avoided.
  • the ballpoint pen After the end of use, the ballpoint pen is brought into a position in which the end of the housing shown on the left in the drawing or a writing tip 22 of the falling body 10, which can also be seen on the left in the drawing, points upward and then the push button 18 actuated, the drop body slides back into the housing 8 after the clamping jaws 14 have been released by actuating the push button and is then held firmly there again.
