DE1955744C3 - Multi-color exchangeable pen with automatic lead reset - Google Patents

Description

The use of the well-known locking crosses or

The invention relates to an interchangeable pen, 55 locking disks also requires space for the emergency in particular Multi-color ballpoint pen, with an agile storage of the central axis. Also is for actuation under spring action there is a complicated fastening of the locking cross Pressure part and a pressure pen or washer fastened in this on a bearing pin necessary, del, which, depending on the inclination or with what an additional effort in assembly costs Rotation position of the pen in recesses in the 60 occurs.

rear pin sleeve part comes to rest and with the The invention is based on the object

Corresponding mine carrier head interacts complicated mechanical components of the locking and brings it into the writing position, where it responds to the release and unlocking mechanism as well as the selection mechanism of a multicolor interchangeable writing pen that includes the effect of a pencil carrier Switching element engages or to make the advance 65 tes so that this Wirteines using another mine carrier is triggered. are manufactured economically

The purpose of the invention is to provide an interchangeable can, the individual parts having a shape To create a pen that is safe to use radio waves to transmit the forces that occur
