Description

Writing instrument

The invention relates to a writing instrument in which a fibre-tip pen is attached to one end.

It is known that the writing tip of writing instruments can be protected or prevented from drying out by attaching or screwing on a sealing cap.

However, the cap can get lost when you need the writing instrument for writing. The writing instrument is usually operated with two hands to open and close the writing instrument. Without the use of a cap, there is a risk of the fiber tip becoming dirty and drying out.

Based on the previously described prior art, the invention is based on the object of improving an improved writing instrument in terms of handling, opening and closing, and which can be produced easily and inexpensively.

This object is achieved according to the invention by a rotary cap housing concept in which the fiber pin can be guided and pushed out through an opening in the rotary cap housing. Since the fiber pin can be pushed in and out of the rotary cap housing as desired, the rotary cap housing covers these two functions of opening and closing without removing the rotary cap housing.

The rotating cap housing is opened and closed by pushing, turning and repeatedly pushing the rotating cap housing in order to prevent the fiber tip soaked in ink or similar from drying out.

The fiber pen has a pin (attached later or already molded on) in the front third towards the fiber tip, which is guided in the pin guide track of the rotating cap housing in order to either push the fiber pen out of the rotating cap housing or secure it in the blind hole-like sealing cap in the rotating cap housing by vertically moving and turning the fiber pen.

Because the rotating cap housing has an inner center bar, an opening for the fiber pen and a sealing cap opposite it is created. This ensures that the fiber pen can be pushed out and secured.

Protection claims extend not only to individual details, but also to their possible combinations, as well as to possible variations, which can be added if necessary.

According to Fig. 1 to 3 of the drawing, a fiber pin according to the invention (consisting of 2$'*, 5, 6, 7, 11) is arranged in a rotating cap housing (l) so as to be displaceable and rotatable (l80°).

The fiber tip (7) of the writing instrument, which is arranged at one end, can be pushed out through an opening (9) in the rotating cap housing (l) and pushed back into the rotating cap housing (l) in order to then be secured in a blind hole to prevent it from drying out.

Functional description

Because a rotating cap housing (1) is arranged on the fiber pen housing (4), these two housings (1, 4) can be moved vertically relative to each other and can also be rotated relative to each other in order to release the fiber tip (7) on the one hand and to protect it from drying out on the other hand by the semicircular cross-section hole (12) in the rotating cap housing (1).

In order to protect the fiber tip (7) from being pressed into the fiber pen housing (4), the vertical movement for this is reduced by half, in contrast to the vertical movement for releasing the fiber tip (7). In addition, grid thresholds (8) are integrated into the track (3) of the pen (2) in the end area of both vertical movements, in order to hold and secure the fiber pen (4) in these end positions.

The fiber tip (7) is thus led out of the secured state by moving the rotating cap housing (l) to the lower stop for the pin (2), then turning the rotating cap housing (l) by 180° to the side stop for the pin (2) and then pushing the rotating cap (l) back until the pin (2) engages, causing the fiber tip (7) to become visible.

If you want to secure the fiber tip (7) again _} the previously described procedure must be repeated in reverse order.

Claims (1)

Applicant:
Walter Funk
Postweg 2
Fellbach Fellbach, 19.05.88 Protection claims 1. Writing instrument, to the end of which a fiber writing tip (7) or the like is attached, characterized by a rotating cap housing (l) through which the fiber pen (4) can be partially pushed out and guided in the longitudinal direction through an opening (9) in the rotating cap housing (l). 2. Writing instrument according to claim 1, characterized in that the opening for the fiber tip (7) becomes a closure cap by vertical displacement and by turning the rotating cap housing (1). 3. Writing instrument according to claim 1 and 2, characterized in that a pin guide track (O) runs in the rotating cap housing (I). 4. Writing instrument according to claims I to 3, characterized in that the pin guide track (3) runs vertically and in a semicircular arc. 5. Writing instrument according to claims I to 4, characterized in that the pen guide track (3) has grid thresholds (8) in each of its two vertical guide ends in order to lock and secure the fiber pen (4) in the closed and open state. -2- &bull; · &igr;&igr; -2- G. Writing instrument according to claims I to 5, characterized in that in the front area of the rotating cap housing (1) there is a semicircular opening (9) for pushing the fiber pen (4) through. 7. Writing instrument according to claims I to 6, characterized in that the housing of the fiber pen (4) merges semicircularly into the circular base body in the front area and thus forms a step. 8. Writing instrument according to claims I to 7, characterized in that ; indicates that through the semicircular opening (9) Opposite in the rotating cap housing (l), a central web (lO) located in the rotating cap housing (l) creates a sealing cap (12) for the fiber tip (7). $ (see Fig.2) c 9. Writing instrument according to claims I to 8, characterized in that i\< indicates that the fibre pin (4) is provided with a fibre tip (7), a tampon soaked in different ink colors, and is sealed at the opposite end of the fiber tip (7) by a sealing plug (5,6). -3-
