Definitions

  • the invention relates to a tube recorder tip with a drop weight body, which is located in an inner bore of a housing which is connected to the writing fluid storage space and carries at its front end a cleaning wire extending into the writing tubes held at the front end of the housing and with a drop weight safety device is rotatably supported about the longitudinal axis of the housing and is in positive engagement with the drop weight body which can be moved axially back and forth with respect to it.
  • a known tube recorder tip of this type (DE-PS 34 34 188), which is designed so that the protrusion of the cleaning wire over the front end of the writing tube can be adjusted by changing the position of the drop weight securing device, the drop weight body extends into the inner bore Sidewall areas of the drop weight safety device suspended so that the axial back and forth by the engagement of the drop weight safety device and the drop weight body Movability allows and in particular the front position of the drop weight body and thus also the protrusion of the cleaning wire over the front end of the writing tube is determined.
  • This known tube recorder tip thus allows the protrusion of the cleaning wire to be adjusted beyond the front end of the writing tube and in particular also the disassembly and reassembly of the falling weight body, without requiring a new adjustment of this protrusion.
  • it has a relatively complicated structure and, in particular, requires a drop weight safety device composed of several parts, one part of which is connected to the housing in a non-displaceable manner after the protrusion has been set for the first time.
  • a tube recorder tip of the type mentioned at the outset is designed in such a way that the drop weight body rests in its front position with a front end face against a contact surface formed in the inner bore and that the plane of the front end face of the drop weight body and the plane of the contact surface are inclined to one another are.
  • the tube pen tip according to the invention there is an inclination, in contrast to conventional tube pen tips, between the surfaces determining the front position of the drop weight body in the inner bore, so that the axial position of the drop weight body and thus also the axial position of the cleaning wire with respect to the writing tube in the front position of the drop weight body can be changed by rotating it with respect to the housing, that is, by turning the drop weight safety device accordingly.
  • the tube recorder tip can be held so that the drop weight body is in its front position and the protrusion of the cleaning wire over the front end of the writing tube can be observed while the drop weight lock is rotated until the desired projection is reached.
  • the falling weight can be secured by gluing, ultrasound welding or similar. be fixed in a non-rotatable manner in the housing.
  • the plane of the front end surface extends perpendicular to the longitudinal axis of the falling weight body, so that the surface inclined in relation thereto is the contact surface in the inner bore, which can be easily formed in this form during the manufacture of the housing, for example by injection molding .
  • the front end surface of the drop weight body that comes into contact with the contact surface will be the surface that lies at the front end of the drop weight body and into which the cleaning wire is inserted.
  • the front end face of the drop weight body can have a length substantially equal to the diameter of the drop weight body and, in contrast, a reduced width due to the tapering of the drop weight body to the front, so that in every possible rotational position of the drop weight body there is an arrangement in which the front end face the Supply of writing fluid from the inner bore to the writing tube is not impaired.
  • An incision can be provided in the rear end of the falling weight body, and the falling weight safety device can have a projection whose thickness is slightly smaller than the clear width of the incision and whose width is larger than the clear width of the incision.
  • the projection extends for positive engagement with the drop weight body in the incision, with its front end in the front position of the drop weight body at a distance from the base of the incision.
  • the tube writer shown in FIG. 1 has a tube writer tip to be described with reference to FIGS. 2 and 3, on the rear end of which a standard writing fluid cartridge 16, which is only partially recognizable, is attached and onto which a holder shaft 17 is screwed on from the rear in the usual way. From the front, a sealing cap 18 of conventional design is screwed onto the tip of the tube recorder and carries a clip 19, which is also common.
  • the tube recorder tip has a housing made of two parts 1, 1 ', and between the parts there is an annular space open to the front, into which a cover sleeve 4 is inserted in a clamping manner and which is formed on the outer surface of part 1' of the housing, helical annular groove covers, so that thereby the inner bore 6 of the housing 1, 1 'is formed in a conventional manner, not shown, with the ambient air connecting pressure compensation chamber.
  • a writing tube 2 of conventional design is attached, which is connected via a connection hole, not shown, to the front end of the inner bore 6.
  • a cleaning wire 8 which is fastened in the front end of a drop weight body 7, which is held in the inner bore 6 so as to be axially movable to and fro and which is located in its front position in the illustrations.
  • the rear end of the inner bore 6 is closed by a cup-shaped falling weight safety device 13 which is inserted into the part 1 of the housing and which has through openings 14 in its bottom wall for connecting the inner bore 6 to the Has writing fluid reservoir, which is formed by the writing fluid cartridge 16 according to Figure 1.
  • the drop weight safety device 13 is rotated about its longitudinal axis, which is also the longitudinal axis of the housing 1, 1 ', the longitudinal axis of the drop weight body 7 and the longitudinal axis of the writing tube 2, approximately 90 ° from the position according to FIG.
  • the projection 15 takes the drop weight body 7 with it during this rotation as a result of engagement with the incision 12.
  • the projection 15 is also ensured that the projection 15 is in positive engagement with the incision 12 in each position of the falling weight body 7, so that it is in the illustrated front position of the falling weight body 7 with its front end in the incision 12, but above the reason is located, that is, the axial reciprocation of the falling weight 7 allows.
  • this has a forward bevel 11, so that there is a substantially rectangular front end surface 10, which has a length corresponding to the diameter of the drop weight body 7 and a width determined by the bevel 11 and from which the cleaning wire 8 stands out.
  • Adjacent to the front end surface 10 of the drop weight body 7 is the contact surface 9 formed at the front end of the inner bore 6, through which the connecting bore of Inner bore 6 passes through to the writing tube 2. While the front end surface 10 of the drop weight body 7 extends perpendicular to its longitudinal axis, the contact surface 9 is inclined to this longitudinal axis, for example at an angle between 10 ° and 30 °.
  • the drop weight body 7 is rotated by 90 ° from a position as shown in FIG. 2 and in which its front end surface 10 is supported on an area of the contact surface 9 which is further back in relation to the position of the writing tube 2, then it is supported the front end face 10 of the drop weight body 7 on a less distant area of the contact surface 9, as can be seen in Figure 3, so that, as also indicated in Figure 3, the drop weight body 7 is displaced further forward in its front position than in the position according to FIG. 2, which, as also indicated in FIG. 3, results in a larger protrusion of the cleaning wire 8 over the front end of the writing tube 2.
