3o.o8.76

In known writing implements of this type, the writing or writing takes place. Rest position of the mine units with push button actuation, wherein the mine units are spring-mounted in the sleeve-shaped housing. The control of the writing or rest position of the mine units usually takes place via link elements, which are located on the front, inner and / or outer surfaces of the writing instrument housing or further control sleeves or the push button, with all components of the control mechanism in the longitudinal axis of the Writing implement are arranged and performed longitudinal movements in this axis or rotary movements around this axis when actuated. A disadvantage of this arrangement is that a large number of components are required for the function, especialeps if more than one pencil lead is to be alternately brought into writing or resting position.

The object of the invention is, in particular, i.e. in addition to that which emerges from the description and claims Tasks a generic writing instrument of assembly technically simple, few components and useful structure indicate in such a way that the mechanics for operating the mine units consists of few components, has memorable and obvious usage properties, as well as manufacturing and is easy to produce in terms of assembly technology.

According to the invention, this task is solved by a mechanism which has a rotating body, the axis of rotation of which is arranged transversely to the »longitudinal axis of the writing instrument and which has control cams , which are also moved together about the axis of rotation with the rotating body and via a transmission element to the

mine units to be moved lengthways, which are arranged in a known manner in 'sleeve-shaped writing instruments, act and thus push these mine units into the writing or rest position, with on the control cams and / or on the transmission element Äastelememte are provided in order to and / or to lock the rest position of the mine units.

This configuration makes a generic writing implement created, especially for ballpoint pens and with increased practical value. The assembly of the ready-to-use writing instrument can be done in a very simple way. The support spring (s) for the writing lead, the writing leads, the transmission body (s) and the rotating body are inserted into the writing instrument case from above introduced, wherein the rotating body with stub axles in snap hollow of the Scheeibgerätehülse, transversely to the longitudinal axis of the writing instrument, rotates into place. After the plug-in latching, the rotating body is in the axial direction of the writing instrument secured in position. After this simple assembly, which does not require any tools, the writing instrument is ready for use. the Writing lead (s) is (are) brought into writing or rest position by turning the rotating body.

An advantageous design of the invention is achieved in that the rotating body is designed as a rotating roller. The roller has one or more elliptical, eccentrically arranged control cams in its axis of rotation; is she drilling towards hers? Axis of rotation for receiving a FEDEI "axis _S sided which the rotating body rotatably in the Schreibgepätehülse superimposed.

The transmission element (s) has (s) a downward bore for receiving lead ends and ribs for lateral guidance of the transmission body on the inner wall of the writing instrument case. A web protrudes upwards, which is pressed by the resilient support of the refill against the control cams in the rotating body and thus ensures positive rotation when rotating the rotating body between the mine and the control cam, so that writing instrument refills can be brought into writing or rest position. Furthermore, the control cams and / or the webs of the transmission body (s) are provided with razor elements ₉ which lock the writing and / or rest position of the pencil leads so that the user can easily perceive the "writing" or "resting" positions of use.

It is also possible that the rotating body has fixed stub axles, according to the invention, which by elastic deformation of the writing instrument sleeve during assembly with the snap cavities latched, with insertion tracks being provided on the writing instrument sleeve.

fig. 5 shows an arrangement of the control cams for a writing instrument with two refills.

The pen (o) designed as a ballpoint pen has a sleeve-shaped housing (1) with snap-in hollows (2) which are used to hold fixed stub axles (3) or resilient stub axles (4) of a spring axle (5). The stub axles (3) or (H) are used to mount a rotary body (6) in the housing (1), the axis of rotation (7) of the rotary body (6) being arranged perpendicular to the longitudinal axis (8) of the writing instrument (o). The axle stubs (U) of the spring axle (5) are compressed during assembly so that their outer edges (9) are not further apart than the width of the rotating body (6). The fixed stub axles (3) of the

Rotary bodies (6) have inclined conical surfaces (lo) which facilitate the elastic deformation of the writing instrument housing (1) during assembly on slideways (11). The transmission body (12) or (12 ^s ) has ribs (13) which serve to guide it on the inner wall of the housing of the writing instrument. Furthermore, the transmission body ( ^s ) (12 or 12 s) has a web (14 or 14 ") which, with the control cams (15 or 15") of the rotating body (6) via the mine (16 or 16 ") ) and whose support spring (17), which is supported on a shoulder (18) of the housing (1), is in a positive connection; when it is rotated, the refill (16 or 16 ") assumes the writing and / or rest position. The control cams (15 or 15 *) can be arranged in the middle, right and / or left or at another point on the rotating body (6);

The transmission body (12 or 12") can have one or more control cams (15 or 15 ") to operate one or more writing leads (16 or 16"). If more writing leads are moved, the transmission bodies (12 or 12 ") slide on a partition (21), or separate large-area sliding surfaces (22) are formed which can slide against one another. For easier introduction of the lead (16 or 16") ) the transmission body (s) (12 or 12 ") are provided with bevels or countersinks (23). For easier
