Definitions

  • the invention relates to a writing instrument with a writing tip holding a shaft portion and a cap for covering the writing tip from a first engagement position to an end position on the shaft part cap.
  • Such writing instruments are known in various forms, especially as a fountain pen.
  • the cap is screwed onto the shaft part for storing the writing instrument in order to protect the writing tip against damage and to prevent, especially in fountain pens, the drying of the writing fluid.
  • covering the writing tip by means of the screw cap allows the insertion of the writing instrument in a jacket pocket o. ⁇ . without the risk of dirtying the garment.
  • the user In order for the cap to fulfill its sealing function, the user should always screw it to the end position on the shaft part. However, it happens that the user unscrews the cap only partially on the shaft part, so that on the one hand there is a risk that no sealing covering takes place, and on the other hand can not be ruled out that the cap dissolves automatically. The latter can also happen when the cap is screwed to the end position, if the friction generated by the threaded engagement is not sufficient to securely hold the cap. Too high a friction when screwing the cap on the other hand carries the risk that the user ends the screwing too soon.
  • the document DE 101 41 488 A1 discloses a pen having a refill tip at one end.
  • a stop is provided which cooperates with a locking device arranged on a holding sleeve to hold the mine in the axial direction in the retaining sleeve.
  • a coil spring is arranged, which biases the stop against the locking device.
  • a cap may be screwed onto the refill to cover the writing tip, the cap being spaced apart from the retainer and locking abutment by the abutment means so as to be rotatable with respect thereto.
  • the force exerted on the mine during screwing in the axial direction counteracts the force of the helical spring. If the lead moves against the spring force into the retaining sleeve, the cap can be rotatably engaged with the locking means to unscrew the locking means from the retaining sleeve and to remove the lead therefrom.
  • the document DE 328203 discloses a fountain pen with a shaft and a cap screwed onto this.
  • a spring holder is arranged, on which a nib is held.
  • the spring holder and the nib are biased by means of a likewise arranged in the shaft coil spring in such a way that the nib protrudes as far as possible from the end of the shaft.
  • a mandrel is arranged in such a way that it comes into engagement with the spring holder in the course of screwing the cap and the spring holder and the writing spring are then displaced together against the spring force in the shaft until the nib completely with completely screwed cap is arranged in the shaft.
  • the cap is screwed onto the shaft part in the first step with a relatively small Aufschraubwiderstand, which, for example, between 1/3 and 2/3, preferably at half of the total Aufschraubweges increases, so that the user receives an indication that he must unscrew the cap even further and preferably to the final position, the increased resistance to screwing also means that the cap safer in this screwed position, preferably in the end position is held and not unwanted detached from its seat.

  • the increased resistance to screwing also means that the cap safer in this screwed position, preferably in the end position is held and not unwanted detached from its seat.
  • the greater resistance to screwing is produced by a spring device acting on the cap.
  • This has a spring acting in the axial direction of the shaft part, for example in the form of a corrugated spring washer.
  • the threaded portions of the shaft portion and the cap coming into engagement with each other over their entire lengths may be formed so that the friction acting between them due to the threaded engagement is substantially equal, while the increased Aufschraubwiderstand by effective only when reaching the intermediate position spring means is caused.
  • Such a spring device is subject to a much lower wear than, for example, threaded sections, which are exposed by appropriate shaping during engagement with each other increased friction.
  • the spring device also has an axially displaceable against the spring force support ring, with which the cap in the intermediate position is engaged, so that it is moved in advancing the unscrewing of this against the force of the spring of a contact shoulder of the shaft portion.
  • the end position can be formed, for example, by abutment of a stop surface, such as the end face of the cap surrounding the cap opening, on a shoulder of the shaft part.

  • the threaded sleeve 2 carries on its protruding from the container 1 part of an external thread on which the cap is screwed, which has a cap member 10 to which a clip 11 is attached in the usual way.
  • a cap ring 12 consisting of metal is placed thereon and ends in a front end face 13.
  • annular space 8 is formed on the shaft part between the container 1 and threaded sleeve 2, which at the front end, so the External thread for screwing on the cap closer end, up to an annular shoulder 8 "( FIG. 3 ) and at the rear end to an annular shoulder 8 'extends, from which the container 1, the annular space 8 partially overlapped forward.
  • a corrugated spring washer 7 is used, which is supported on the one hand on the rear annular shoulder 8 'of the annular space and on the other hand on a support ring 6, which is located in the annular space 8 and unscrewed or not screwed into the intermediate position cap
  • the inner diameter of the support ring 6 is slightly larger than the outer diameter of the threaded sleeve 2 in the region of the annular space 8, so that the support ring on the threaded sleeve can be moved back and forth.
  • In the front region of the support ring 6 has a radially outwardly projecting, circumferential rib area or a shoulder.
  • the spring washer 7 is then compressed as a result of engagement of the cap ring 12 and the support ring 6 and the resulting axial displacement of the support ring, whereby an acting in the axial direction of the shaft part resistance to screwing, ie the resistance to screwing takes for the User noticeable towards the resistance, which has acted when screwing from the first engagement position to the intermediate position.
  • the cap is screwed to its end position when the end face 13 of the cap ring 12 has come to rest on the end face 9 of the container 1 of the shaft part ( FIG. 3 ). In this position, the cap is kept loaded by the action of the spring washer 7 in the axial direction, so that the risk of accidental release of the cap is significantly reduced.
