pen

The invention relates to a ballpoint pen with a tubular cylindrical body and a tubular cylindrical cap which is displaceably arranged on the body, and means for mutual locking of the cap and the body with each other coming in _"engagement? Projecting and receiving portions. '. ■

Such protruding and female parts are as a bayonet lock or thread known. Both known designs, as well as the known pressing of a cap, ensure not maintaining a certain mutual angular position between the body and the cap. That leads to one Unattractive appearance if decorative motifs are arranged on these parts, the conformity of which is then no longer guaranteed is. Pressing on still leads to particular difficulties, if the assembly is to be dismantled later.

_ΛΛ 1411847

The spring 146 is in the retracted position Cartridge is not subject to any stress ^ so that put their coils together. When the appropriate cartridge by moving its slider to the writing position is brought, a train is exercised on each one, and as a result the great length of the wire that forms it, which is the maximum length for a spring length with a given spring diameter is, the force to be exerted on the slide is relatively small. If the slider is in the row division .. | Finding cartridge is vacated from its seat 133 is the cartridge through, the effect of during the previous out- - ■ Pushing the tensioned spring pulled back until ye Holder 138 abuts against wall 181 with its edge 185 '. One such a spring corresponds to the conditions for the proportionately large strokes, which are required for the cartridge, "making the actuation of the slide among the most favorable Conditions allows and effective retrieval of the cartridge guaranteed in their withdrawn position. A self • frequently repeated operation of one working in the above manner Feather does not change its properties.

The assembly and disassembly of the various parts is convenient and is already apparent from the description above. The attachment of the cap is shown below. the body egg · and the removal of the same from the body described · Hack <Insertion of the lamella 163 in the cap 172 in such a way that its approach 166 through the leastsa? 1? 6 kicks, pushes, 'mas Md Kapp ©

on the body. The approach 166 is e.g. . the tool provided for this purpose, in order to avoid that its edge 168 abuts the edge of the body and to allow the body to pass the window 176. When the cap is pushed on correctly, the edge 182 of the lamella 163 abuts against the wall 181, whereby the elastic Block 190 is squeezed and when the window 125 «learn Approach 166 is opposite, this snaps due to the elastic

^ ity of the lamella 163, the leg 165 of which is aligned with its edge 171 supported on the cap 172, into the window, whereby the cap and the body both in the longitudinal direction as such be locked with regard to their angular position in the desired position. The production of a certain angular position between the body and the cap provides the G-ewahr for that on these parts, the correct mutual ornaments provided Have positions. The action of the elastic block 190 seeks to remove the cap 172 from the body 120, whereby every slight shift between the body
