Definitions
- the invention relates to a pen
- a holding sleeve for at least partially receiving the lead
- a locking device to be actuated by turning for locking the lead and the holding sleeve to one another
- the cap is axially displaceable with respect to the locking device from a first operating position, in which it is rotatable with respect to the locking device, into a second operating position, in which it is rotationally coupled to the locking device.
- Pens of the type mentioned are known, for example from DE 36 44
- the cap has a sealing insert which tightly encloses a writing tip of the lead.
- the mine is held stationary opposite the locking device.
- the sealing insert moves along the writing tip.
- Cap for moving from its first operating position into its second operating position is not approximately axially displaced, but is radially compressed. This handling is perceived as impractical.
- a further disadvantage of this solution is that the cap must have a comparatively large diameter so that it can be compressed radially.
- the invention has for its object to overcome the above disadvantages and in particular to provide a pen in which the cap reliably seals the writing tip of the refill, but which is nevertheless easy to use and takes up as little space as possible.
- the lead is axially displaceable with respect to the locking device, namely by at least a distance which is equal to the distance between the first and the second operating position of the cap.
- the pin is designed in such a way that the cap does not have to be displaced with respect to the lead during the axial displacement for moving from the first operating position to the second operating position, so that adverse effects on a seal due to such displacement are excluded.
- a radial pushing in of the cap is not necessary, which makes handling easy.
- the resetting device is preferably a helical spring. A particularly simple embodiment is thereby achieved.
- the cap is preferably designed to be screwable to the lead. This results in a particularly high sealing effect.
- the locking device is particularly preferably designed to be screwable to the holding sleeve.
- Such a screw connection is, on the one hand, particularly reliable and, on the other hand, particularly easy to handle.
- the locking device has a stop facing away from a working end of the mine, with which a stop on the mine facing the worker interacts.
- the lead is reliably locked within the holding sleeve.
- a component of a coupling device serving for the rotary coupling of the cap to the locking element lies on the end face of the cap facing the locking device in the attached state.
- At least one cam on the cap is used for rotational coupling of the cap to the locking device.
- at least one cam on the locking device is preferably used for rotationally coupling the cap to the locking device. This configuration ensures a particularly reliable rotary coupling.
- the lead is rotatable with respect to the locking device and is rotationally coupled to the holding sleeve. This prevents the mine from turning when the cap is screwed on or off.
- the single figure shows a longitudinal section and three cross sections of a particularly preferred embodiment of the pin according to the invention.
- a pin which has a lead 10, a holding sleeve 12, a locking device 14 and a cap 16.
- the cap 16 has a sealing insert 18 with an internal thread 20. With the internal thread 20, the cap 16 is screwed onto a corresponding external thread 22 in the area of the writing tip 24 of the lead 10. This connection of the cap 16 to the lead 10 ensures a high degree of tightness.
- the locking device 14 is screwed into an appropriate internal thread 28 on the holding sleeve 12 by means of an external thread 26. In doing so, it strikes with its side 30 facing away from the writing tip 24 against a side 32 of a projection 34 formed on the lead 10 facing the writing tip 24.
- the lead 10 is rotatably held with respect to the locking device 14.
- lugs 36, 38 are formed which, when the lead 10 rotates, abut on lugs 40, 42 within the holding sleeve 12 and thus limit the turning of the lead 10 to a predetermined amount.
- a coil spring 44 presses the lead 10 against the locking device
- Cams 46, 48 are provided on the locking device 14.
- Cams 50, 52 are provided on the cap 16.
- the cap 16 together with the lead 10, is axially displaceable with respect to the locking device 14 and the holding sleeve 12 - to the right in the drawing - until the cams 46, 48 abut the locking device 14 and / or the cams 50, 52 on the cap 16 , It is expressly pointed out that the drawing is not to scale. The distance that can be moved axially is approx. 1 mm.
- the cap 16 can easily be unscrewed from the lead 10 or from the writing tip 24 thereof. If the friction between the locking device 14 and the mine 10 does not already prevent the mine 10 from turning when unscrewing, such a turning is prevented at the latest by the strikes of the lugs 36, 38 on the lugs 40, 42.
- Screwing the cap 16 onto the lead 10 or the writing tip 24 also works without any problems.
- the cap 16 is axially screwed onto the lead 10 against the restoring force of the spring 44 - to the right in the drawing - until the cams 46, 48 on the one hand and 50, 52 on the other hand during rotation strike each other around the longitudinal axis of the pin, which corresponds to a different operating position of the pin.
- the cap 16 and the sleeve 12 are then rotated relative to one another about the longitudinal axis of the pin. Since the cams 46, 48 abut the cams 50, 52, the locking device 14 is screwed out of the holding sleeve 12 by rotating the cap 16 against the holding sleeve 12.
- the mine 10 can then be removed and possibly exchanged for another mine.
