j "Pen with push mechanism and retaining clip"

The innovation relates to a pen with a push mechanism and retaining clip.

There are pens are known in which the pencil lead when you press one on the write mine remote. End of the pen protruding button from the conical at the writing end Pen sleeve emerges and locks into place. If you press the button again, the lock is released and the refill is released by a tension spring, which is tensioned when exiting, into the sleeve withdrawn. In the case of the known pens, the locking and unlocking takes place through the cooperation of a projection on the sleeve or the slide adjusted by the push button with a heart curve groove on the slide or the sleeve.

To facilitate assembly, pens with retaining clips are known (GM 7 OMA- 768), in which the projection that cooperates with the heart curve groove is not on the inner surface of the sleeve,

but is arranged on the outside of a clip attachment, which is inserted into the sleeve for fastening the clip to the sleeve will. The projection consists of a head bolt, the free end of which is hemispherical. The bolt can move in a slot in the attachment of the clip *

There are also pens with retaining clips known (GM 7 655), where the head bolt is replaced by a loose ball which is located in an embossed cup of the clip attachment = the clip attachment is in this known pen in a section of the sleeve, in which it is held by flaps that are cut on the edge of the sleeve and bent later will.

The innovation is based on the task of designing such a pen so that it is easier to assemble is, in particular, that the punch-out weakening the sleeve and the subsequent bending of the fastening tabs is no longer necessary.

This object is achieved in the pen of the innovation in that the clip attachment with the drop by a JPett attached ball together with dome slide until its bent end clicks into a slot from above in the sleeve is inserted, as is known for pens with a projection on the clip attachment (GM 7 044 768} ..

The drawing shows schematically and partially in section a preferred embodiment of the pen of Innovation.

In the drawing is:

F i g. 1 a longitudinal section through the printing mechanism of the pen and

F i g. Figure 2 is a perspective view of the sleeve, clip and slider prior to assembly.

In this drawing, the sleeve is labeled “2, the slide 3”, the clip 5, its attachment 6 and the ball 4. The inwardly bent end 7 of the clip attachment engages in the slot 8 of the sleeve Z when the parts are assembled.
