Definitions

  • the invention concerns a pen with a barrel and an applicator, in which the barrel has a depression for gripping and the applicator has a contour that is not rotationally symmetrical with reference to a longitudinal axis of the pen and may be adjusted around the longitudinal axis in the direction of rotation with reference to the depression for gripping.
  • Pens of the type indicated in the introduction are known from DE 26 43 816 A1 for example. According to this the applicator, which has a nib, is held in the barrel in the axial direction only because of frictional resistance. It is very difficult to adjust the frictional force that occurs in this properly. That is to say if it is too big, it is difficult to adjust from a first to a second rotational position. If it is too small, there is the risk that the applicator will become loose from the holder. A further difficulty consists of the frictional force being able to change over time through ageing and environmental influences, particularly changes in temperature, for example. DE-AS 1 275 410 shows a further pen of the type indicated above.
  • the invention is based on the task of developing the pen of the type indicated in the introduction further in such a way that simple production is ensured. Furthermore, the applicator should also be held on the barrel in a reliable way.
  • the task set is carried out by a screw connection for locking the applicator in the axial direction and/or in the direction of rotation.
  • a screw connection is understood to be not only a connection with a screw but also a connection with a nut.
  • the invention provides a tool, by means of which the screw connection for locking the applicator to the barrel may be produced in the axial direction and/or in the direction of rotation, that is to say it may be screwed together and loosened, that is to say unscrewed.
  • This tool may be a separate part.
  • a torque limit is provided working in the direction for locking, but not in the direction for loosening the screw connection when the screw connection is actuated.
  • This torque limit should prevent parts of the pen from being damaged if too great a force is applied for screwing the screw connection together.
  • the actuator has a first contour, which works together with a second contour of the screw connection that matches the first contour when actuating the screw connection and the first and/or the second contour is/are unsymmetrical in such a way that the torque that may be applied with the actuator is limited.
  • the torque limit working in only one direction is produced by a lack of symmetry in a contour, which plays a part in the screw connection working together with the actuator.
  • Such lack of symmetry is particularly simple to produce. Tooth type structures may be provided for example, which have a steeper edge on one side than on the other side.
  • the actuator has a longitudinal slot. It is so flexible through this that it may get out of the way if the slot is reduced in order to make it possible or at least easier to slip over when the limit torque is exceeded.
  • the actuator has an outer contour that matches the inner contour of a recess in the screw connection.
  • a tool for actuating the screw connection, which is introduced into a recess in the screw connection in order to actuate the screw connection.
  • the screw connection has an outer contour that matches an inner contour of a recess in the actuator. In this case the actuator would then have to be put on the screw connection.
  • an element of the screw connection to lie on an inner wall of the barrel and a first partial area of the inner wall with the element of the screw connection to have a higher friction coefficient than a second partial area.
  • a latching device which allows the applicator to be applied in preset rotational positions with reference to the depression for gripping.
  • the applicator not to be able to be applied to the barrel in any possible rotational position with reference to the depression for gripping. Rather two or more possible rotational positions are preset in a fixed way.
  • This arrangement prevents the pen from being put together with a rotational position of the applicator with reference to the depression for gripping that is not correct. Furthermore, the latching device prevents the rotational position of the applicator (unintentionally) changing with reference to the depression for gripping when screwing the screw connection together.
  • Figure 1 a diagrammatic longitudinal section view of a pen according to a preferred example embodiment of the invention
  • Figure 2 the same view as figure 1 , but of another example embodiment without cap,
  • FIG. 3 seven diagrammatic views of a nut used for locking for the pens according to figures 1 and 2,
  • Figure 4 a diagrammatic partial section view of a tool for tightening and loosening the nut according to figure 3,
  • Figure 5 the tool according to figure 3, but in another rotational position
  • Figure 6 a view of the tool in the direction of arrow
  • Figure 7 a view of the tool in the direction of arrow
  • the pen according to figure 1 has a barrel 10, which is screwed together with a cartridge chamber 12. A longitudinal axis of the pen is indicated with the letter L. An applicator 14 is inserted into the barrel 10, which has a nib 16 and a disc store 18. A protective cover or cap is indicated with reference number 20.
  • An ink cartridge 22 is inserted into the cartridge chamber 12.
  • the ink cartridge 22 has a closing ball 24, which lies inside the ink cartridge 22 after it has been inserted.
  • Behind the ink cartridge 22 is a replacement ink cartridge 23, which has not been inserted yet, for which reason its closing ball 25 still closes it.
  • the pen according to figure 2 differs from the one according to figure 1 only in that the inserted ink cartridge 22' of the pen according to figure 2 is longer than the ink cartridge 22 of the pen according to figure 1 and that no replacement ink cartridge is provided. Therefore in the following reference is always made to the pen, by which both embodiments are meant.
  • a locknut 26 is used for locking the applicator 14 to the barrel 10. It has an inner thread 28, with which it is screwed onto a corresponding outer thread 30 of the applicator 14.
  • a flange 32 of the locknut 26 is supported on an indentation 34 in the barrel 10.
  • a flange 36 of the applicator 14 is supported on a face 38 of the barrel 10. In this way the applicator 14 is locked in the axial direction with reference to the barrel 10.
  • the flanges 32 and 36 also lie on the indentation 34 or face 38 with frictional resistance, there is also a certain locking in the direction of rotation.
  • a tool 40 which is shown in figures 4 to 7, is used to tighten and loosen the locknut 26.
  • the tool 40 represents an actuator that matches the screw connection that has the locknut 26. It has profiling at its working end, which is shown on the left side in figures 4 and 5, in the form of longitudinal ribs, one of which is indicated with reference number 42 as an example.
  • the working end of the tool 40 indicated is inserted into a recess 44 in the locknut 26 to screw together and unscrew the locknut 26.
  • the recess has longitudinal grooves that match the longitudinal ribs 42, one of which is indicated with reference number 46 as an example. Both the longitudinal ribs 42 and the longitudinal grooves 46 are unsymmetrical when seen in the circumferential direction.
  • the locknut 26 locks if the locknut 26 is turned with the tool in the direction for loosening. That is to say the then working edges of the longitudinal ribs 42 and the longitudinal grooves 46 are comparatively steep. However, if the locknut 26 is screwed together with the tool 40, flatter edges of the longitudinal ribs 42 and the longitudinal grooves 46 come into effect, for which reason only a limited torque may be transferred from the tool 40 to the locknut 26. If this torque is exceeded, the tool 40 slips through. As the longitudinal ribs 42 must jump from one longitudinal groove to another in this, they must be able to get out of the way radially inwards. To make this movement for getting out of the way possible the tool 40 is provided with a longitudinal slot 48 at its working end, which makes it possible to get out of the way.
  • the tool 40 is provided with a knurl 50 on the end opposite its working end for better handling. Screwing together and unscrewing the locknut 26 by hand is made easier through this.
  • the barrel 10 has three depressions for gripping distributed around its circumference, one of which is illustrated in figure 9 and indicated with reference number 52.
  • the applicator 14 and therefore the nib 16 may take up three different positions with reference to this depression for gripping 52, that is to say a neutral position, a position turned by +15° and a position turned by -15°.
  • the frictional force on both flanges 34 and 36 is used for locking in these three rotational positions to some extent.
  • three latching ribs are provided on the applicator, one of which is indicated with reference number 54 as an example, and five latching grooves are provided on the barrel 10, one of which is indicated with reference number 56 as an example.
  • the three latching ribs 54 and the five latching grooves 56 make the three rotational positions illustrated in figure 9 possible.
  • ribs and grooves may be provided for further locking in the direction of rotation, turned by 180° with reference to the latching ribs 54 for example.
  • the barrel 10 is made in two layers in the example embodiment illustrated. It consists of an inner sleeve 58 and a coating 60.
  • the inner sleeve 58 is made from ABS for example, whereas the coating 60 is made from a considerably softer plastic in order to achieve the desired feel. Even though this is not illustrated in the drawing, the inner sleeve 58 may have breaks in it like windows, through which the coating 60 is sprayed, particularly in the area of the locknut 26. As the coating 60 has a higher friction coefficient, further locking of the locknut 26 is achieved through this, which opposes unintentional loosening of the locknut 26.
  • the applicator 14 has a series of three markings 62.
  • An arrow 64 is applied to the barrel 10.
  • the arrow 64 points to a certain one of the markings 62 according to the rotational position in order to indicate to the user which rotational position the applicator 14 and therefore the nib 16 is in with reference to the depression for gripping 52.
