Clip arrangement on pens

The innovation concerns a clip arrangement on pens » in particular multi-colored ballpoint pens or pens with an oil-free clip-carrying insert in the coat hUXae uxid of a coat sleeve closing off, with the insert: a screw cap that can be screwed in the axial direction.

A known GIipanOrdordnung is that the Clip with an angled retaining bracket through a slot adapted to the cross-section of the retaining bracket is inserted inwards in the jacket sleeve, with a hole in this bracket, which is positioned coaxially to the longitudinal axis of the pen when the clip is inserted and through which a Threaded pin is guided to the clip in its

to hold the position used. The threaded stem serves at the same time for the screw connection between the insert and the end cap. As especially multi-color ballpoint pens or pins are made of metal, so is the end cap that is visible from the outside ale metal part formed. If you were to provide the threaded pin on this end cap, so this would require a relatively high material requirement, which is extremely uneconomical. The insert arranged in the interior of the metal jacket can, however, be designed as a plastic part. In the known construction, however, the threaded pin cannot be formed in one piece with the insert piece be, white]. Otherwise it will prevent the clip from being pushed in through the slot in the jacket sleeve would. The threaded pin must therefore be designed as a separate component, which after insertion of the clip in the jacket sleeve through the hole in the bracket of the clip i.n a correspondingly arranged The hole in the insert corner is screwed in; on what then the end cap can be screwed onto the threaded socket in the insert. It is It can be seen that such a construction is disadvantageous because of the cost of components and assembly time.

The innovation is based on the task of a clip arrangement to create soft with the least possible expenditure on components and assembly time and nevertheless all requirements regarding the aesthetic design as well as the stability of the Arrangement does justice. In particular, the Glip arrangement should be designed so that the threaded pin

and the insert E.la formed as a single component be able to.

This object is achieved daturch that in the jacket sleeve axially in the area of the insert extending, in the direction of the end cap tapering Schll.z is attached, through which a Locking member engages in a recess of the insert piece that the portion protruding into the interior of the jacket sleeve of the Sperrgliec.es one that can be inserted through the wider end of the slot, but wider than that has a narrower end of the slot formed cross-section, and that the insert piece when it is screwed with the end cap axially in the casing is movable.

An advantageous embodiment is that the Insert piece in one piece with a threaded pin associated with a threaded hole in the end cap is provided.

Another advantageous feature is that the clip is designed as a locking member which can be inserted into the insert piece.

Yet another advantageous embodiment exists in that the clip lubricates an annular retaining bracket outside of the jacket sleeve on the pin of the Elneatzstückes can be plugged between this and the end cap is and a separate locking member engages in the slot and the insert.

Yet another useful development is that the locking member in the area of the jacket sleeve is in has a notch corresponding to the narrowest point of the slot

It is also an advantageous feature that the locking member has a cylindrical cross-section and the slot consists of a bore adapted to the cylinder passage and a narrower, rectangular base seat adjoining it.

Using the following description of the exemplary embodiments of the innovation shown in the drawing this is explained in more detail.

The multi-color ballpoint pen shown in Figure 1 consists essentially of a jacket sleeve 10, in which the four colored leads 12 are arranged in a known manner. The colored leads 12 are each fastened to slides 14 which are guided in slots 16 of the casing 10. The slides 14 are fixed in the jacket sleeve 10 by means of return springs 18 arranged sleeve 2C connected. In addition, the slide 14 engage through corresponding slots 22 of a Guide sleeve 24 * which is used in a known manner for setting and reading the selected colored lead 12, which is why these details are not explained in more detail.

Above the sleeve 20 there is an insert piece 26 within the jacket sleeve 10, which is in one piece is provided with a threaded pin 28. Tune end cap 30 is provided with a threaded hole 32, and can be stolen with the insert 26. The insert piece 26 has a recess 34 which extends in the radial direction and into which a retaining bracket 36 of a clip designated as a whole by 38 is pluggable. To the clip 38 with its retaining bracket 36 to be able to insert into the recess 34, is the Jacket sleeve 10 with e: provided with a total of 40 designated slot, which can be seen more clearly from FIG. The slot consists of a lower one wide section 40i and a sefatnäleron section 40b * extending in the direction of the end cap 30 As can be seen in particular from Pig.3b, possesses the retaining bracket 36 de.3 clip 38 a notch 42,

which the width of the retaining bracket to the width of the narrower section 40b of the slot 40 is reduced, while the remaining part of the retaining bracket is approximately the cross section of the bitter portion 40a of the Slot 40 is adapted.

Before screwing the closure cap 30 onto the threaded pin 28, the retaining bracket 36 of the clip 38 is pushed through the wider section 40 into the interior of the jacket sleeve 10 and into the recess 34 of the insert piece 6. Then the end cap 30 is screwed onto the threaded pin 28 * whereby after the end cap 30 runs up against the end edge 44 of the jacket sleeve 10, the end cap 30 is fixed in the axial direction and when the screwing movement continues, the insert 26 pulls in the axial direction against the end cap 30, so that the retaining bracket 36 migrates into the narrower section 40b of the slot 40, where the jacket sleeve 10 engages in the notch 42 and thus secures ^{the clip 38 against sliding out of the recess 3 Z *}

Figures 4 and 5 show a different embodiment, in which a clip 138 is used, the retaining bracket 136 of which is annular and encloses the threaded pin 128 of the insert 126, in such a way that the circumference 8 surface θ H (> of the annular retaining bracket 136 after the The end cap 130 remains visible from the outside by screwing on the end cap 130. In this construction, the retaining bracket 136 is pushed onto the threaded pin 126 in the axial direction outside the jacket sleeve 110, whereupon the end cap 130 is pushed onto the threaded pin 128

is unscrewed. Before the end cap 130 is screwed on, a locking member HB is inserted into a recess 134 of the insert 38 126 pushed through a slot 140 in the jacket sleeve 110 »The locking member 14b has an essentially cylindrical cross section and a notch 142 in the form of an annular groove. the UOa has the wider section of the slot UO larger diameter of the locking member 148 corresponding to a circular cross-section »while attached to it a narrower section 140b in a rectangular shape connects) its parallel side edges when screwing the end cap 130 to the insert piece 126 and engage in the annular groove-shaped notch 142 of the locking member 148 during the axial movement of the attachment piece 126 caused by this. With this construction the insert 126 prevented by the locking member 148 from rotating, so that a firm connection between the end cap 130 and the insert 126 can be produced. With comparable constructions was previously used instead of the locking member a screwdriver, which in a corresponding thread of the insert was screwed in, white axially was impassable. Di * ae construction is obvious more complex than the solution now proposed.
