Definitions
- the invention relates to a writing instrument with a sleeve having an open front end and a therein, by means of a rotary member having a spindle drive mechanism slidably held mine, the cooperating with the rotary member mine itself forms the spindle and is held in the sleeve against rotation.
- DE 32 10 681 A1 describes a writing instrument with a front and a rear rotatable body part and a mine.
- the rear body part is rotatably connected to the front body part via a snap connection (annular groove and annular rib).
- the mine has a screw thread and is threadedly engaged with the front body part.
- the mine At its rear end, the mine by means of protruding tongues, which are inserted in key slots in the head of the rear body part, held against rotation. Since the mine is held only at its end, a non-rotatable holder is limited. Therefore, and also because of the tongues always a short piece of mine remains unused in the front part of the writing instrument. Removal of the remainder of the mine to replace the mine is difficult because the mine piece can not be moved out of the writing instrument due to the absence of thread in its end portion and due to the protruding tongues.
- a propelling pencil with a spindle drive-type feed mechanism in which a lead screw pin engages by means of a nose in the thread of a threaded spindle in order to advance a lead during rotation.
- the construction of this rotary pencil is relatively expensive, since several structural parts must be provided in order to ensure a reliable feed mechanism.
- the nose can easily break off, so that then no more advance the mine is possible .
- the CH 167 532 A also describes a pivot pin with a threaded spindle, which cooperates with a spindle nut for the purpose of advancing a mine.
- the spindle nut is located slightly in front of the center of a hollow grip sleeve firmly in this.
- the threaded spindle extends through the spindle nut, and it is axially moved forward upon rotation of a rear knob.
- the front end of the spindle pushes the mine in front of him. Since the mine is present in front of the threaded spindle, it can - with usual length of the pivot pin - be short, so that a frequent change of the mine is necessary.
- a writing instrument in which also a relatively short lead with a spindle drive advanced and a hold of the mine is realized only by a narrowed diameter in the front region of the writing instrument is known from GB 142 270 A.
- a similar pivot pin with a spindle drive in which a driver arranged in the rear part of the sleeve of the pin has a head for moving the lead located in the front part of the sleeve out of the pivot pin, is disclosed in GB 1914-24035A.
- the object of the invention is therefore to provide a writing instrument of the type mentioned above, which provides a secure anti-twist for the mine, which is simple in construction and inexpensive to manufacture, and which is also reliable in use.
- the writing instrument should also be suitable for long mines, with a removal of the mine or the remaining mine piece to be facilitated.
- a writing instrument which is characterized in that elastic lamellae are provided in the interior of the sleeve, which engage in recesses provided on the outside of the mine. Through this engagement, the elastic blades can safely hold the mine during its advance movement by the spindle drive mechanism against accidental rotation and ensure precise guidance of the mine inside the sleeve. A lateral, unwanted movement of the mine can be made impossible.
- the elasticity of the lamellae means that the lamellae can engage in the assembly in the recesses of the mine in a simple manner and without much resistance.
- the elastic lamellae can hold the mine resilient and act in the event of impact of the writing instrument on a hard surface damping the mine.
- the elasticity of the lamellae can result, for example, from the choice of appropriate materials and / or from the fact that the lamellae do not exceed a corresponding wall thickness.
- the fins may have a wall thickness of a few tenths mm, about 0.3 mm to about 0.6 mm.
- the writing instrument additionally has the advantage that it is essentially formed only of two construction parts. By the simple spindle drive mechanism in which the mine itself forms the spindle, a highly secure and reliable rotating mechanism is obtained in which additional sleeve parts are unnecessary, so that the writing instrument in the production is simple and inexpensive. In addition, the length of the sleeve for the mine can be exploited almost entirely, so that long mines can be used and an early refilling of a mine is avoided.
- the thread provided for the formation of the lead as a spindle advantageously extends over the entire length of the lead.
- a particularly efficient effect of the lamellae with regard to torsion protection, guidance and suspension is given when the lamellae extend over the length of the sleeve. Also, it is favorable for the support of the mine, if at least three, preferably four, slats are provided at equal angular intervals.
- the lamellae are integral with the sleeve.
- the fins may also be held on the inside of the sleeve in a longitudinal groove in the sleeve. Due to this simple construction of the writing instrument, the slats can also be replaced if necessary. On the other hand, it is possible here, if desired, to produce the sleeve from metal, whereas the blades can be made of plastic.
- the recesses are formed in the mine by sawtooth-shaped in cross-section longitudinal grooves.
- the rotary part is arranged at the front end of the sleeve.
- an outer rotary member may be provided which is rotatably connected to an inner spindle nut. Again, therefore, because the rotary part is present in the front area of the writing instrument, a "one-hand" operation is possible.
- the spindle nut cuts a thread into the mine during operation. It is advantageous if the internal thread of the rotary part or the spindle nut is designed as a thread cutting device for the mine. For increased effectiveness as a thread cutting device, the rotary part or the spindle nut may be made of metal, for example. In this case, any conventional refills can be used in the writing instrument, wherein the thread can be cut in a simple manner upon rotation of the rotating part in the mine. To protect the mine during operation, it is favorable if the mine has a preformed thread. It is also advantageous that the spindle nut or the rotating part of the same material, namely plastic material, such as the sleeve may be formed.
- the rotary part can be releasably connected to the sleeve by a snap connection.
- the snap connection can be formed in a manner known per se by, for example, a circumferential bead on the rotary part or on the sleeve, which in a recess or groove of the sleeve. or the rotary part can retract.
- the detachable connection of the rotary member with the sleeve and the arrangement of the rotary member at the front end of the sleeve is also advantageous in that a change of the mine with removed rotary member can be made particularly easily.
- a simple assembly is also achieved when the rotary member is rotatably supported on the sleeve by means of a ring clamp. This is particularly favorable when providing an outer rotary member which is rotatably coupled with a separate inner spindle nut, low.
- the writing instrument not only with a conventional pencil lead, but also with a colored lead.
- at least one window can be provided on the sleeve to make the respective color of the mine in the writing instrument for the consumer and user immediately visible.
- a viewing window is also advantageous in that the user can then also recognize whether he must soon make a mine change.
- the viewing window is arranged in the front to middle region of the writing instrument or the sleeve.
- the writing instrument is suitable as a disposable product (disposable pen) with already inserted mine or as a housing with refill option.
- a closure cap can be provided, which is detachably connected to the rear end of the sleeve.
- a mine can be easily inserted from the rear end into the writing instrument.
- an eraser or the like is provided at the rear end of the sleeve, which is removable for the purpose of replacement (including the mine).
- the removal of a "spent" refill can be done in the front, through the front open end of the sleeve, for example by simply unscrewing the refill manually, which is therefore easily possible because the fins no longer engage the refill.
- the writing implement or the sleeve and the rotary part gron- ⁇ NEN natural substances or synthetic materials or mixtures thereof are used thereof, which has been shown that the production of the sleeve and / or of the rotary part made of nylon (polyamide 6.6) an optimal compromise with respect to strength, Elasticity of the slats, grip of the outside, etc. provides.
