Description

The invention relates to a pen for writing and / or painting purposes with a shaft and a disposed within the shaft and axially adjustable in the longitudinal direction of the shaft between an active position and a rest position mine.

Pins in which the mine is mechanically adjusted between an active position and a rest position, are known in many designs and are used, for example, as a ballpoint pen. In so-called pivot pins or rotary ballpoint pens, a rear portion of the shaft is rotated relative to a front portion to axially adjust the mine. Another possibility is push pins, e.g. Retractable ballpoint pen having at its rear end an actuating or push button, by the operation of the mine between the active position and the rest position is moved. The advance of the mine is accomplished, for example, by means of a spindle drive or a thread, so that a rotational movement of the shaft or a movement of the actuating knob in the longitudinal direction of the shaft transferred to the mine and thus this is axially adjusted. However, such a construction is often technically complicated, since a large number of additional components is needed.

It is therefore an object of the invention to provide a pen for writing and / or painting purposes, in which the mine is adjustable in a simple manner and reliable.

The object is achieved by a pen for writing and / or painting purposes with the features of claim 1. The pin comprises a shaft and a mine, which is disposed within the shaft and between an active position and a rest position axially in the longitudinal direction of the shaft is adjustable , In the rest position, the mine is completely disposed within the shaft and in the active position the mine protrudes with a protrusion from a front end of the shaft. The pin further comprises a perpendicular to the longitudinal direction of the shaft between an active position and a rest position movable actuator, which is operatively connected to the mine via a connecting element such that the mine during a movement of the actuating element perpendicular to the longitudinal direction of the shaft between the rest position and the Active position is axially adjustable in the longitudinal direction of the shaft.

In other words: The actuator is - relative to a horizontally held pin - vertically up and down, so relative to a central longitudinal axis of the pin in the radial direction movable, the mine horizontally back and forth. The movement of the actuating element and the movement of the mine thus take place in mutually perpendicular directions. The actuating element and the refill are thus coupled in terms of movement via the connecting element, so that the mine is displaced or displaced axially, ie along or parallel to a central longitudinal axis of the shaft, upon actuation of the actuating element. The actuating element is arranged in a rear portion or end of the shaft so that it is operatively connected to a rear end of the mine and this moves for movement in the active position to a front end of the shaft.

Under active position in this case is the position of the mine or the actuating element to understand when the pin is used, that is in writing position or in a state of use, ie, the mine is extended. In the rest position of the mine or the actuating element, the pin is in the non-use state, ie the mine is retracted.

The idea of the present invention, therefore, is to provide a mechanical pen in which the mine is reliable, repeatable and movable in a user-friendly manner from its rest position to the active position. In other words, a movement of the actuating element which is perpendicular to the longitudinal direction is converted, when it is actuated, into a longitudinal movement of the mine. By the connecting element there is the advantage that the distance of the actuating element, which covers this in a movement from the rest position to the active position, may be shorter than the required to achieve the active position of the mine movement distance of the mine in the longitudinal direction. In addition, the movement of the actuator perpendicular to the longitudinal direction, compared to known pins in which the actuator as well as the mine is moved in the longitudinal direction, less space within the shaft is required so that it is more compact overall, ie. may be shorter or, for the same size, a longer refill can be used to make a longer lasting pen.

The connecting element is preferably rotatable on the shaft in a central portion, a first end portion of the connecting element is preferably on the actuating element and a second end portion of the connecting element is preferably mounted directly or indirectly on the mine. The connecting element is thus fixedly and rotatably mounted on the shaft about a rotational axis extending both perpendicular to the longitudinal direction of the shaft and perpendicular to the direction of movement of the actuating element, in other words around a transverse axis of rotation. A central portion of the connecting element thus forms a pivot point or fixed point about which the connecting element or both the first and the second end portion of the connecting element are rotatable, wherein the position of this fixed point relative to the shaft so relative to the shaft is not changed, so based on the shaft does not move longitudinally. The first and the second end portion of the connecting element are also fixed to the actuating element or attached to the mine, so that the relative position of the first end portion relative to the actuating element and the relative position of the second end portion relative to the mine in a movement from the rest position to the active position and vice versa also not changed. If the actuating element is moved perpendicular to the longitudinal direction of the shaft, a force is thus exerted on the first end portion of the connecting element. Thereby, the first end portion of the connecting element is also moved perpendicular to the longitudinal direction of the shaft, so carried by the actuating element, so that this causes a rotation of the connecting element to the fixed point and thus a movement of the second end portion and moves the mine from the rest position to the active position becomes. In other words, the movement of the actuating element perpendicular to the longitudinal direction of the shank is converted by the connecting element into a movement of the mine in the longitudinal direction of the shank. The connecting element thus has the function of a lever.

The connecting element is preferably a single connecting element or an integrally formed connecting element, which thus comprises only one connecting member, which in a central portion rotatably on the shaft, with a first end portion on the actuating element and with a second end portion of the connecting element directly or indirectly on the Mine is stored. In order to enable a reliable rectilinear adjustment of the mine, the connecting element comprises in a further preferred embodiment, at least two connecting members, that in particular a first connecting member and a second connecting member, which are each hinged together. In each case adjacent connecting links are thus in their mutually facing end portions each pivotally connected to each other about a pivot axis. The pivot axes about which each two connecting members, for example, the first and the second connecting member are pivotally arranged to each other, also extend perpendicular to the longitudinal direction of the shaft and also perpendicular to the direction of movement of the actuating element. In addition, the pivot axes are translationally displaceable in the longitudinal direction and perpendicular to the longitudinal direction, wherein the movement takes place along one of the rotation about the axis of rotation of the fixed to the shaft central portion of one of the connecting links following, curved line. A first connecting member, which is connected to the actuating element, is fixed in a fixed position rotatable about the axis of rotation on the shaft. The arranged on the actuating element first end portion of the connecting element is thus formed by the first link, the second end portion which is fixed to the mine is formed by the second or depending on the embodiment of a third or further link. Several connecting links have the advantage that with a constant movement distance of the actuating element perpendicular to the longitudinal direction of the shaft a longer movement distance of the mine in the longitudinal direction can be achieved.

It would be conceivable, for example, to arrange a third or further connecting links in the form of a link chain between the actuating element and the mine, wherein adjacent connecting links are each hinged, ie pivotally connected to one another about a pivot axis.

Preferably, the actuating element in the rest position is at least partially from a first side surface of the shaft and in the active position at least partially from a second, the first opposite side surface of the shaft. In the rest position, the actuating element closes off in particular flat with the second side surface of the shaft, in the active position, the actuating element in particular ends flush with the first side surface of the shaft. As a result, a disturbing projection of the actuating element is largely avoided. For axial adjustment of the mine, the respective protruding part of the actuating element can be achieved, so that the actuating element can be moved by pressing the respectively protruding section from the active position into the rest position and vice versa.

In a further preferred embodiment, the actuating element has a first longitudinal section extending in the longitudinal direction of the shaft and a longitudinal section extending at right angles to the longitudinal direction and arranged at least partially within the shaft, wherein at least the first longitudinal section is in the rest position at least partially out of the first side surface of the shaft and the second longitudinal section is in the active position with a free end at least partially out of the second, the first opposite side surface of the shaft protrudes. The first longitudinal section forms in this case, for example, a retaining clip to keep the pen when not in use, for example, in a pen compartment of a briefcase or in a breast pocket. For this purpose, holding or clamping means for the captive insertion of the pin can be formed at the free end of the first longitudinal section. Characterized in that the first longitudinal portion protrudes from the side surface of the shaft only when the mine is in the rest position, contamination, such as the chest or briefcase is reliably avoided. The second longitudinal section is at least partially held or guided in a rear region of the shaft and cooperates with an inner peripheral surface of the shaft, for example in the sense of a sliding pairing.

In a further preferred embodiment, the free end of the second longitudinal section has a smaller width than an adjoining middle section of the second longitudinal section, wherein the free end is arranged in the rest position and / or in the active position at least partially within a recess of the shaft , The recess is formed in a subsequent to the second side surface portion of the shaft. The second longitudinal section or its free end thus prevents, in particular, both during the movement of the actuating element perpendicular to the longitudinal direction of the shaft and in the rest position and in the active position, a movement of the actuating element in the longitudinal direction of the shaft, since this to form a longitudinally acting positive connection is held in the recess.

Furthermore, the actuating element preferably has at least one stop surface, which in the active position and / or rest position with an inner circumferential surface of the shaft cooperates. This stop surface is arranged, for example, at the free end of the longitudinal portion and cooperates with a recess of the shaft defining inner peripheral surface to prevent the movement of the actuating element in the longitudinal direction. In addition, the adjoining the free end middle portion of the second longitudinal portion may form a stop surface, which rests in the active position on an inner circumferential surface of the shaft. As a result, the user, for example, clarified the achievement of the active position of the mine as an end position and avoid excessive pressing of the actuating element. Another abutment surface is formed for example by a rear, ie the rear end of the shaft facing the end face of the actuating element, which abuts against an inner peripheral surface of the rear end of the shaft and is pressed during the movement of the actuating element from the rest position to the active position against this to completely convert the force resulting from the movement of the actuating element into a rotation of the connecting element. Furthermore, the mine is held in the active position and prevents an independent movement of the mine back into the rest position.

In order to fix the connecting element or its first end portion to the actuating element, the actuating element, in particular the second longitudinal portion of the actuating element in an advantageous embodiment, a recess in which the first end portion of the connecting element is mounted directly or indirectly. The recess extends both perpendicular to the longitudinal direction of the shaft and perpendicular to the direction of movement of the actuating element. If the connecting element comprises a plurality of connecting links, the first end section of the first connecting link is mounted in the recess. The connecting element is fixed in such a way in the recess that a movement in the longitudinal direction of the shaft is prevented, so that slipping out of the connecting element is not possible. The recess may be formed for example in the form of a hole, so that the connecting element can be fixed within the recess by means of a pin or bolt.

In an advantageous development, the recess extends at least partially into the actuating element from a front end side of the actuating element, in particular from a front end side of the second longitudinal section of the actuating element in the longitudinal direction of the shaft, the first end section of the connecting element being movably mounted in the recess. Under the front end is to understand the mine and the front end of the shaft facing the end face of the actuating element, the recess thus extends perpendicular to the longitudinal direction of the shaft and perpendicular to the direction of movement of the actuating element, ie in the transverse direction and in the direction of a rear end of the shank. Thereby, the connecting element and the actuating element can be mounted in a simple manner by, for example, a pin or bolt fixed to the connecting element is held movably in the recess. During a movement of the actuating element of the first end portion of the connecting element is carried by this, thus also moves perpendicular to the longitudinal direction.

In particular, the pin has a locking and / or latching device with which the refill can be fixed axially in the active position and / or in the rest position so that it reliably remains within the shaft during the writing process in the active position and in the rest position. For example, the locking and / or locking device arranged on the connecting element locking and / or locking elements, such as latching lugs, which in the active position and / or in the rest position, ie in a respective end position of the mine and the actuating element, in a recess of Shank, for example, engage a correspondingly shaped groove. Another possibility is that the connecting element is rotated during actuation of the actuating element to the extent that a by a return element, which biases the mine in the active position in the axial or longitudinal direction, force exerted on the mine force turning back the connecting element prevented. Such a locking and / or locking device is particularly suitable if the connecting element comprises only one connecting member.

In a preferred embodiment, the locking and / or locking device is formed by a joint connecting a first and a second connecting member, which pivotably connects the first and the second connecting member about a pivot axis. The joint is movable out to lock over a dead center, when the actuator is moved from the rest position to the active position. In other words, a joint connecting the two connecting members is moved beyond a plane formed by the axis of rotation and the bearing position of the connecting element or of a second connecting element on the mine. This creates a self-locking system, which prevents an independent movement of the mine from the active position to the rest position.

To support the movement of the mine after the use of the pin from the active position to the rest position, the pin, as already mentioned, comprise a restoring element, in particular a spring, which biases the lead in the active position in the axial or longitudinal direction. As soon as the actuating element is moved from the active position to the rest position and the locking or locking position is released, the mine is almost automatically moved back from the active position to the rest position. The spring is arranged for this purpose in a front region of the shaft and presses the mine in axially in the longitudinal direction to a rear portion of the shaft. The restoring element also ensures that the connecting element is securely held on the actuating element, in particular in the recess.

In a further preferred embodiment, the pin comprises a guide element arranged inside the shank between the mine and the connecting element and axially adjustable in the longitudinal direction for guiding the mine. The guide member has a receptacle for receiving a rear end of the mine. The connecting element or a connecting member or a second, front end portion of the connecting element or the connecting member is mounted on the guide member and is thus indirectly operatively connected to the mine. By the restoring element and the guide element is always pressed against the connecting element, so that a reliable hold of the connecting element is ensured in the guide element. Such a lead guide has the advantage that a tilting or migration of the mine is prevented during the axial adjustment. In a structurally simple variant, the guide element has a sleeve-shaped receiving portion for receiving the lead and an adjoining thereto guide portion which cooperates with an inner peripheral surface of the shaft and slides during the axial adjustment along this and on which the connecting element or the connecting member or is attached. The outer peripheral surface of the guide element is formed in accordance with the inner peripheral surface of the shaft, so for example, has a quadrangular or triangular cross-section.

In an advantageous embodiment, the pin comprises at least one guide means for guiding the connecting element or a connecting member, in particular a front, first end portion of the connecting element or a connecting member, and / or for guiding the actuating element in the shaft during movement of the actuating element and the mine. As a result, a transverse movement or tilting of the connecting element and / or the actuating element during actuation is reliably avoided.

For example, the pin comprises at least a first guide means for guiding the connecting element in the shaft during a movement of the actuating element, which comprises a recess formed in the shaft, in which the connecting element is guided directly or indirectly. In other words, the connecting element is at least partially guided or slidably mounted within a recess formed on the inner circumferential surface of the shaft. For example, the connecting element by means of a pin in a recess formed as a slot in the axial direction slidably guided so that tilting of the connecting element and a migration of the mine can be avoided. Alternatively, the connecting element may be mounted only within the guide element, which in turn is supported with an outer peripheral surface on an inner side of the shaft or on the actuating element, more precisely on the first longitudinal section thereof.

For guiding the actuating element in the shaft during a movement, the pin in a further preferred embodiment at least a second guide means for guiding the actuating element in the shaft during a movement of the actuating element, which at least one projecting from an inner peripheral surface of the shaft and perpendicular to the longitudinal direction comprising the shaft extending projection which cooperates with at least one on a side surface of the actuating element, in particular on a side surface of the second longitudinal portion formed perpendicular to the longitudinal direction extending receptacle in the sense of a sliding pair. Upon actuation of the actuating element perpendicular to the longitudinal direction, this is thus guided within the shaft. A deviating from perpendicular to the longitudinal direction of movement of the actuating element is not possible, so that tilting or tilting is reliably prevented.

The receptacle is preferably over from a projecting from a side surface of the actuating element, in particular of the second longitudinal portion, perpendicular to the longitudinal direction of the first longitudinal portion and at least partially along the side surface extending projection and an overhanging over the side surface of the end portion of the actuating element formed in particular of the second longitudinal section. The rear end portion of the actuating element is at least partially flat against a rear inner peripheral surface of the shaft and thus prevents movement of the actuating element in the direction of the rear end of the shaft.

Fig. 1 shows an exploded view of a pin 2 for writing and / or painting purposes with a shaft 4 and a mine 6. The shaft 4 comprises a first elongated shaft portion 4a, a second elongated shaft portion 4b and a third cone-shaped shaft portion 4c. The first shaft part 4a and the second shaft part 4b each have at least substantially a U-shaped cross-sectional profile, wherein the open sides of the shaft parts 4a, 4b facing each other in the assembled state. In the assembled state, the second shaft part 4b is arranged within the first shaft part 4a and held in this example by clamping or additionally glued or fixed by means of a tongue and groove connection. At a front end portion of the second shaft part 4b holding elements 8a are formed, which engage positively in the assembled state in complementarily formed holding elements 8b of a rear end portion of the third shaft portion 4c. The first outer shaft part 4a may be made of wood, for example, to give the user a good tactile and visual impression. In principle, the shaft 4 may also be formed in one piece, but a multi-part shaft 4 has the advantage that on the one hand the assembly of the pin 4 is facilitated and on the other hand, the mechanical components necessary for actuating the lead 6 are largely not visible to the outside.

The refill 6, in the present case by way of example a ballpoint pen refill, with a reservoir 6a for storing the ink paste and a writing tip 6c carrying a writing ball 6b is arranged inside the shaft 4, more precisely within its inner part, namely the second shaft part 4b and axially adjustable in the longitudinal direction L of the shaft 4 between an active position and a rest position. At rest ( Fig. 2 to 8 ), the mine 6 is completely disposed within the shaft. In the active position ( Fig. 9 to 14 ), the refill 6 protrudes with its front end, that is to say part of the writing tip 6c and the writing ball 6b, with a protrusion from a front end of the shank 4 or of the shank part 4c.

At a rear end, the pin 2 in a direction perpendicular to the longitudinal direction L extending movement direction B between a rest position and an active position movable actuator 10, which is operatively connected to the axial adjustment of the mine 6 with this via a connecting element 12, so that the mine at a movement of the actuating element perpendicular to the longitudinal direction of the shaft between the rest position and the active position is axially adjustable in the longitudinal direction of the shaft. The actuating element 10 has a first longitudinal section 10a, which extends in the longitudinal direction L of the shaft 4 and an adjoining main body or second longitudinal section 10b, which extends from the first longitudinal section 10a perpendicular to the longitudinal direction L on.

Within the shaft 4 between the lead 6 and the connecting element 12, a guide element 14 for guiding the lead 6 is arranged, which is axially adjustable in the longitudinal direction L, so that the connecting element 12 is indirectly connected via the guide member 14 with the mine 8. The connecting element 12 can be fastened to the guide element 14 in the assembled state. The guide element 14 has a receptacle 14 a for receiving a rear end of the mine 6. A part of an outer circumferential surface 14b of the guide member 14 is formed complementary to an inner circumferential surface of the shaft 4 and the shaft part 4b, respectively, to allow smooth sliding.

At a front end, the pin 2 has a return element, in the present case a spring 16, which surrounds the writing tip 6c in the assembled state and the mine 6 biases in the active position in a longitudinal direction L of the shaft 4. In the assembled state, the spring 16 is supported with a first end 16a on a front end face 18 of the mine 6 or of the reservoir 6a and with a second end 16b on an inner peripheral surface of the cone-shaped shank part 4c, in particular on an abutment surface formed on the inner peripheral surface. In the active position, the spring 16 is biased, so compressed, in the rest position, the spring 16 is relaxed. By the spring 16, the guide member 14 is always pressed in the direction of the rear end of the pin 2 and thus against the connecting element 12, so that an attachment of the connecting element 12 in or on the guide member 14 is not mandatory.

According to the embodiment, the connecting element 12 comprises a first connecting member 12 a and a second connecting member 12 b, which are pivotally connected to each other about a pivot axis S. The first link 12a comprises two mutually parallel plate-shaped elements which are connected at two opposite end portions via a respective web 20. The joint 22 connecting the first connecting member 12a to the second connecting member 12b is formed in the exemplary embodiment by one of these webs 20 and a recess 24 in the second connecting member 12b.

The connecting element 12, according to the embodiment, the first link 12a is mounted in a central portion 26a rotatably about a rotation axis D on the shaft 4, more precisely on the inner part of the shaft 4, namely the shaft part 4b. For this purpose, the plate-shaped elements of the first connecting member 12a each have a through hole 34 through which a connecting element 30, in the present case a cylindrical pin is inserted, which in turn is mounted in a recess 32 of the shaft 4 and the second shaft part 4b. A first end portion 26b of the connecting element 12 or the first connecting member 12a is on the actuating element 10, namely on the second longitudinal portion 10b, a second end portion 28a of the connecting element 12 and the second connecting member 12b is attached to the guide element 14, that is mounted indirectly on the mine 6. The mutually facing end portions 26 c, 28 b of the first link 12 a and the second link 12 b are pivotally connected via the hinge 22.

To guide the connecting element 12 in the shaft 4 and the second shaft part 4b during a movement of the actuating element 10 and the mine 6, the pin 2 has guide means 36. The guide means 36 comprises according to the present embodiment, a recess 38 formed in the shaft 4 and the second shaft part 4b, in which the connecting element 12 is indirectly guided. Further, the guide means 36 comprises a connecting element 40, for example also a cylindrical pin which is inserted through a through hole 42 introduced in the second connecting member 12b and a through hole 44 inserted in the guide element 14. The connecting element 40 is mounted in the recess 38, which in the present case is designed as a slot, in order to guide the connecting element 12 or the second connecting member 12b during a movement of the lead 6 from the rest position into the active position and vice versa.

To guide the actuating element 10 in the shaft 4 and the second shaft part 4b during a movement of the actuating element 10 and the mine 6, the pin 2 has guide means 46. The guide means 46 comprises a protrusion 50 projecting from an inner circumferential surface 48 of the shank 4 and the second shank part 4b and extending perpendicularly to the longitudinal direction L of the shank 4. Further, the guide means 46 comprises on a side surface 52 of the actuating element 10 or its second longitudinal section 10b formed perpendicular to the longitudinal direction L and in the assembled state parallel to the projection 50 extending receptacle 54. In a movement of the actuating element in the direction of movement B, the receptacle 54 and the projection 50 cooperate in the sense of a sliding pair.

The receptacle 54 is thereby projecting from a side face 52 of the actuating element 10 or its second longitudinal section 10b projecting, perpendicular to the longitudinal direction L of the first longitudinal portion 10a projection 56 which extends to a free end 49 of the second longitudinal portion 10b and an end portion 58 of the actuating element 10 or its second longitudinal portion 10b projecting with a projection over the side surface 52 in the direction of a rear end of the shaft.

In the Fig. 2 to 8 the pin 2 is shown in different views, while this is in the non-use state, both the mine 6 and the actuator 10 are thus at rest. The mine 6 is arranged completely in the rest position within the shaft 4. The actuating element 10 projects partially in the rest position, namely with its first longitudinal section 10a and part of the second longitudinal section 10b with a projection A ₁ from a first side surface 60a of the shaft 4 or from an upper side of the shaft 4. The connecting element 40 is according to Fig. 2 in which, for a better illustration of the guide means 36, the pin 2 without the outer, first shaft part 4a is shown, arranged in the rest position at a rear end of the recess 38. Fig. 3 shows a pin 2 with outer first shaft portion 4a, which covers the guide means 36 and consists for example of wood or plastic.

The 4 and 5 each show a longitudinal section along the line IV-IV according to Fig. 2 or the line VV according to Fig. 3 . Fig. 6 shows a detailed view of a rear portion of the pin 2. Both the actuator 10 and the mine 6 and the connecting element 12 are in the rest position. The first connecting member 12a of the connecting element 12 is arranged in the rest position almost parallel to the actuating element 10. A first end portion 26b of the first connecting member 12a is mounted in a recess 62 of the actuating element 10 and the second longitudinal portion 10b of the actuating element 10. The recess 62 extends from a front end face 64 of the actuating element 10 and the second longitudinal portion 10b of the actuating element 10 in the longitudinal direction of the shaft partially into the actuating element 10 into it. The connecting element 12 and the first connecting member 12a is movably supported in the recess 62 by the cylindrical web 20 arranged in the recess 62. When the operating member 10 is moved perpendicular to the longitudinal direction L of the shaft in the direction of movement B, the first end portion 26b of the connecting member 12 and the first connecting member 12a is carried by the operating member 10 and thus also moved perpendicular to the longitudinal direction L of the shaft. This causes a rotation of the connecting element 12 and the first connecting member 12a about the axis of rotation D or to the fixed point F on which the connecting element is stationary, but rotatably mounted on the shaft 4. The second end portion of the first link 12a is thereby moved both in the longitudinal direction L of the shaft 4 and upwards, ie perpendicular to the longitudinal direction L of the shaft 4 and thereby pushes the second link 12b connected thereto via the link 22 and thus the lead 6 in the longitudinal direction L of the shaft in the active position.

The free end 49 of the second longitudinal section 10b of the actuating element 10 has a smaller width B ₁ , as a width B _{2 of} an adjoining central portion 66 of the second longitudinal section 10b. The free end 49 is partially disposed in the rest position in a recess 68 of the shaft 4 in order to avoid jamming or blocking of the actuating element 10 at the beginning of the movement.

In the active position, the refill can be fixed by a locking device, which is realized here by the joint 22 connecting the first and the second connecting member 12a, 12b of the connecting element 12. By rotation of the first link 12a about the pivot point, the joint 22 is moved beyond the dead center and thereby prevents uncontrolled return movement of the lead 6 from the active position to the rest position during the writing process.

In the Fig. 8 to 13 the pin 2 is shown in different views, while this is in use or in writing position, both the mine 6 and the actuator 10 are thus in the active position. In the active position, the second longitudinal portion 10b of the actuating element 10 partially protrudes with a free end 49 of a second side surface 60b of the shaft 4, which faces the first side surface 60a of the shaft with a projection A ₂ . The mine 6 protrudes with a projection C from the front end of the shaft 4.

The free end 49 of the second longitudinal section 10b of the actuating element 10 has a smaller width B ₁ than a subsequent central section 66 of the second longitudinal section 10b. The free end 49 is arranged completely in a recess 68 of the shaft 4 and also projects beyond the second side surface 60b. In order to move the refill 6 from the active position back to the rest position, the locking device can be released by pressure on the free end 49 of the actuating element and the mine 6 by rotation of the connecting element 12 and the connecting member 12 a by means of the spring 16, which is biased in the active position, moved back to the rest position.

As in particular in the detail view in Fig. 12 can be seen, the actuating element 10 has a stop surface 70 which rests in the active position on the inner peripheral surface 48 of the shaft 4 and prevents further movement of the actuating element 10 and signals the user to reach the end position. The abutment surface 70 is formed by a lower side surface 72 of the central portion 66 of the second longitudinal portion 10 b of the actuating element 10.

Fig. 15 shows an exploded view of another embodiment of the pen 2 for writing and / or painting purposes, which has substantially the features according to the above-described pin 2, so mainly reference is made thereto. Corresponding features are identified by identical reference numerals. The pin 2 comprises a shaft 4 with a first elongated shaft part 4a, a second elongate shaft part 4b, a third cone-shaped shaft part 4c and a fourth shaft part 4d, which in the present case serves in particular for connecting the second shaft part 4b to the third shaft part 4c. The refill 6, again by way of example a ballpoint pen refill, with a reservoir 6a for storing the ink paste and a writing tip 6c carrying a writing ball 6b is arranged inside the shaft 4, more precisely within its inner part, namely the second shaft part 4b, and between an active position and a rest position axially adjustable in the longitudinal direction L of the shaft 4. In the rest position, the lead 6 is arranged completely inside the shank, in the active position the lead 6 protrudes with its front end with a protrusion from a front end of the shank 4 or the shank part 4c. A return element or a spring 16 in turn biases the lead 6 in the active position in a longitudinal direction L of the shank 4.

At a rear end, the pin 2 in turn in a direction perpendicular to the longitudinal direction L extending movement direction B between a rest position and an active position movable actuator 10 with first longitudinal portion 10a and second longitudinal portion 10b, which for the axial adjustment of the mine 6 with this over a Connecting element 12 is operatively connected, so that the mine is axially adjustable in a longitudinal direction of the shaft during a movement of the actuating element 10 perpendicular to the longitudinal direction of the shaft between the rest position and the active position.

The difference over in the Fig. 1 to 14 The guide element 114 is arranged within the shaft 4 between the lead 6 and the connecting element 112, and axially adjustable in the longitudinal direction L, so that the connecting element 112 indirectly via the guide member 114 is connected to the mine 8. The guide element 114 has a receptacle 114a for receiving a rear end of the mine 6. A part of an outer peripheral surface 114b of the guide member 114 is complementary to an inner circumferential surface formed of the shaft 4 and the shaft part 4b, to allow easy sliding.

The connecting element 112 includes, for example, a first connecting member 112a and a second connecting member 112b, which are pivotally connected to one another about a pivot axis S. The first link 112a comprises two mutually parallel plate-shaped elements, which are connected at two opposite end portions via a respective web 120. The joint 122 connecting the first link 112a to the second link 112b is in turn formed by one of these webs 120 and a recess 124 in the second link 112b.

The connecting element 112, according to the embodiment, the first link 112a is mounted in a central portion 126a rotatably about a rotation axis D on the shaft 4, more precisely on the inner part of the shaft 4, namely the shaft part 4b. For this purpose, the plate-shaped elements of the first connecting member 112a each have a recess 134 through which a connecting element 130, in the present case a cylindrical pin is inserted, which in turn is mounted in a recess 132 of the shaft 4 and the second shaft part 4b. A first end portion 126b of the connecting element 112 or the first connecting member 112a is attached to the actuating element 10, namely at the second longitudinal portion 10b, a second end portion 128a of the connecting element 12 and the second connecting member 112b is attached to the guide element 14, ie indirectly to the Mine 6 stored. The mutually facing end portions 126c, 128b of the first link 112a and the second link 112b are pivotally connected via the hinge 122.

For guiding the connecting element 112, the pin 2 has guide means 136 according to an alternative variant. The guide means 136 comprises according to the present embodiment, a connecting element 140 (shown in phantom), for example, also a cylindrical pin which is mounted within the guide member 114 and secured thereto.

In this case, instead of the through-bore, a recess 142 is provided at the second end section 128a of the connecting element 112 or the connecting element 112b, which surrounds the connecting element 140 fixed within the guide element 114 in such a way that the connecting element 112 engages within the guide element 114 during a movement in the axial direction is held.

In the Fig. 16 (Resting position) and 17 (active position) is a section of a rear end portion of a pin 2 (not explicitly shown) shown, in which the connecting element 212 comprises only a first, so a single link, so that the connecting element 212 is integrally formed. Unless the mine has to travel a long distance, so no translation is needed so large, such a design offers the advantage that material can be saved.

The connecting element 212 is rotatably mounted on the shaft 4 about a rotation axis D. With a first end portion 226b, the connecting element 212 is mounted in a recess 62, which extends from a front end face 64 of the actuating element 10 in this hineinerstreckt. A front end portion 226c of the connecting element 212 is mounted on the guide element 14 and thus indirectly connected to the mine 6. In the active position, the connecting element 212 extends substantially in the longitudinal direction L of the shank 4, ie the front end section 226b and the rear end section 226c are arranged one behind the other in the longitudinal direction. The connecting element 212 is rotated by the actuation of the actuating element 10 so far around the axis of rotation that a guide element 14 against the front end portion 226 c of the connecting element 212 pressing restoring force of the return element is insufficient to cause a turning back of the connecting element 212. As a result, the mine 6 is locked in the active position. Only a movement of the actuating element of the active position in the rest position causes rotation of the connecting element 212 and thus releasing the lock. In the rest position, the connecting element 212 lies flat against a rear end face 214 of the guide element 214 and extends substantially transversely to the longitudinal direction L of the shaft 4, ie, the front end portion 226b and the rear end portion 226c are arranged side by side in the transverse direction.
