Definitions

  • the operating element is a mechanical component that can be operated from the operating side of the housing and, depending on the operating position, makes a mechanical engagement either with an adjusting mechanism for displacing the spring assembly or with an adjusting mechanism for moving the piston.
  • the spring unit is to be regarded as a unit which is necessary for writing with the fountain pen and at least one ink conductor with a writing spring arranged thereon and an ink tank with a piston arranged therein together with adjustment mechanism for the piston.
  • the housing is the part of the writing instrument that is touched by the operator when writing and filling the ink tank and is the outermost shell of the writing instrument. In the housing all necessary facilities are accommodated, which allow a continuous flow of ink to a nib.
  • the longitudinally axially displaceable spring unit is housed. This means that the spring assembly can be moved within the housing, so that the nib protrudes more or less from the writing side of the housing to reduce or increase the length of the writing instrument.
  • this longitudinal axial displaceability can be dimensioned such that the spring assembly can be fully retract into the housing, so that on the write side, the nib of the spring unit has completely disappeared. This allows a much more compact design of the writing instrument can be achieved.
  • the ink tank and the housing are to be dimensioned such that the ink tank does not lead to mechanical interference with the operating element or a mechanism arranged therein when the spring unit is retracted.
  • the writing instrument according to the invention can provide two different functions through this structure with the operating element.
  • the first function is the longitudinal axial displacement of the spring assembly while the second function is the movement of the piston of the ink tank.
  • the first operating mode can be achieved, for example, in that the operating element is arranged in a first operating position, so that a mechanical connection with the spring assembly or an associated adjusting mechanism takes place, so that the spring assembly can be moved by axial axial axial rotation by turning the operating element.
  • the second function namely the operation of the piston, can be initiated by moving the operating element into a second operating position.
  • the control can be deducted for this purpose on the operating side of the case of this, much like a clock crown for adjusting the time.
  • a mechanical connection can be made between the operating element and the piston or an associated adjustment mechanism in order to move it in a longitudinal-axial direction within the ink tank.
  • the writing instrument according to the invention can accordingly have a significantly more compact design without retraction of a conventional piston tank by retracting the spring assembly than is the case with conventional piston filling springs.
  • the spring unit may have a first adjusting means, which in the first operating position with a first drive means forms a first adjusting drive. This converts a rotation of the first drive means in a longitudinal axial movement of the spring assembly, wherein the first drive means rotatably connected to the operating element.
  • the first adjustment means and the first drive means may, for example, be in pairs be performed interacting mechanical components that allow a conversion of a rotation to a longitudinal axial movement.
  • the first drive means is non-rotatably connected to the operating element, so that a rotation of the operating element exclusively for rotating the first drive means leads, which in turn leads by the interaction with the first adjusting means to a longitudinal axial displacement of the spring unit.
  • the piston also has a second adjusting means which, in the second operating position, forms a second adjusting drive with a second drive means.
  • This converts a rotation of the second drive means in a longitudinal axial movement of the piston, wherein the second drive means, at least in the second operating position rotatably connected to the operating element. In the second operating position, therefore, the mechanical connection to the first drive means is released and the rotation of the operating element exclusively leads to a movement of the second drive means, which initiates a movement of the piston in the tank.
  • the first adjusting means is designed in the form of a rotatably mounted adjusting bushing with a curved path formed therein, engage in the engagement means.
  • the adjusting bushing has a second sprocket, which can be brought into engagement with a first sprocket rotatably connected to the operating element.
  • the first and the second ring gear are dimensioned such that they form an engagement only in the first operating position and are therefore solved on the route between the first and the second operating position.
  • a Curved track is to be understood in this context as a radial milling in the rotatably mounted adjusting bush, which is designed such that non-rotatably executed, but longitudinally displaceable engagement means in the curved path with rotating adjusting bushing would perform an axial movement.
  • the curved path is therefore mechanically comparable with a thread with a fairly large pitch.
  • the first drive means has a first sprocket, which consists, for example, of a uniform arrangement of teeth distributed on a circumference, which can be brought into engagement with a correspondingly formed second sprocket.
  • the heights of the teeth of these two sprockets are further dimensioned such that they are smaller than the distance between the first operating position and the second operating position of the operating element, so that the mechanical connection between the first sprocket and the second sprocket separates as soon as the operating element the first operating position is brought into the second operating position.
  • first sprocket is arranged on a sprocket body, wherein the sprocket body rotatably connected to the control element and is mounted displaceably in the longitudinal axial direction on the control element.
  • the engagement between the first sprocket and the second sprocket can therefore tolerate a non-exact alignment of the first sprocket and the second sprocket to each other, so that damage to the sprockets can be avoided.
  • An equally advantageous embodiment further comprises a spring which is adapted to press the sprocket body in a remote from the operating side position. This can be caused by correct alignment of the sprockets to each other a flush intervention by suspension of the sprocket body.
  • the second drive means in the form of a first rotatably mounted spindle body is formed with a arranged on an external radial toothing, wherein the second adjusting means is designed in the form of a lijnsaxial displaceable and connected to the piston second spindle body, with the first spindle body is engaged.
  • the radial toothing of the first spindle body can be brought into engagement with a drive toothing on the operating element.
  • the radial toothing is arranged on the first spindle body in such a way that the drive toothing engages with the radial toothing only in the second operating position.
  • the radial toothing could be on an outside, i.
  • the length of the teeth on the first spindle body and on the drive toothing could preferably lie below the length of the distance between the first and the second operating position of the operating element.
  • a guide portion of the operating part is arranged axially displaceable in a housing-fixed part of the writing instrument.
  • a locking device is arranged, which is adapted to releasably engage the guide portion in two longitudinally spaced apart positions.
  • the locking device can be realized by any means in which, for example, a deformable or compressible locking element bears against a support surface and by the action of a force This position can be solved by deformation or compression again.
  • This locking element may be designed as a sheet or a ring, which may be made of a plastic material or a metal.
  • the guide portion of the operating part is arranged axially displaceable in a housing-fixed part of the writing instrument, wherein an inner side of the housing-fixed part and an outer side of the guide portion have three annular grooves, of which either the housing-fixed part or the guide portion accommodates two longitudinally spaced-apart annular grooves and in at least one annular groove, a latching element is arranged, which is at least partially elastically detachable in the respective no latching element accommodating annular groove can be introduced.
  • a releasable connection which is permanently reliable.
  • the locking element is a retaining ring made of a resilient material which is arranged in the annular groove of the housing-fixed part and has at least one region whose local diameter falls below the diameter of the annular grooves of the control unit.
  • This area could be designed approximately in the form of a flat or the retaining ring could generally have an elliptical or other, deviating from a circular shape design.
  • a latching element in the form of a retaining ring made of a resilient material is arranged in each annular groove of the control unit, which has an interruption and whose average diameter exceeds the diameter of it accommodating annular groove in the unloaded state.
  • the guide section or the housing-fixed part has at least one shoulder, which is arranged at least adjacent to an inner annular groove of the guide section.
  • a shoulder can also be arranged adjacent to the outer of the two spaced-apart annular grooves. This serves to provide a mechanical stop, at least in the second operating position, in order to exclude any incorrect operation or malfunction of the operating element. Furthermore, it is ensured by the inner shoulder, that the control element can not be completely pulled out of the writing instrument and can be lost.
  • the writing instrument on a linear guide for non-rotating guiding of the spring assembly within the housing, which can be approximately in the form of an elongated slot in which a slider or an axis is displaceable executed. This allows a reliable and precise adjustment of the spring unit can be achieved and the spring unit can not twist during writing.
