Description

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

Pens in which the mine is mechanically adjusted between an active position and a rest position are known in various designs and are used, for example, as ballpoint pens. In the case of so-called rotary pens or rotary ballpoint pens, a rear section of the shaft is rotated relative to a front section in order to adjust the mine axially. Another possibility are push pens, e.g. push ballpoint pens, which have an actuating or push button at their rear end, by actuating the pushbutton, the mine is moved between the active position and the rest position. The lead is advanced, for example, with the help of a spindle drive or a thread, so that a rotary movement of the shaft or a movement of the actuating button in the longitudinal direction of the shaft is transmitted to the mine and this is thus adjusted axially. However, such a construction is often technically complex, since a large number of additional components is required.

From the US 2007/223986 A1 For example, a pen is known in which an actuating element is arranged laterally on the shaft, wherein the Actuating element protrudes laterally from the shaft in the rest position of the mine and is withdrawn into the shaft in the active position.

Also the DE 36 06 336 A1 discloses a writing implement which has an actuating element which can be moved transversely to the longitudinal center axis of the writing implement and which can be lowered into or removed from a recess of the writing implement.

DE 43 33 150 C2 discloses a lateral actuation device for a lead writing instrument in order to move its lead from the retracted position into the writing position and vice versa by means of lateral forces acting by means of a rotatably mounted thrust conversion element. The actuating device comprises a lateral clip that extends approximately parallel to the mine axis, a cross bar at the upper end of the clip, which is inclined relative to the perpendicular to the mine axis and can be moved in a correspondingly inclined cross channel - above the mine - and a recess in the cross bar, into which a wedge-shaped locking tip of the rotatably mounted thrust-relocating element protrudes, the other end of which is designed for direct or indirect contact with the mine.

It is therefore the object of the invention to propose a pen for writing and / or painting purposes in which the lead can be adjusted in a simple and reliable manner.

The object is achieved by a pen for writing and / or painting purposes with the features according to claim 1. The pen for writing and / or painting purposes comprises a shaft and a mine, which are arranged within the shaft and axially between an active position and a rest position is adjustable in the longitudinal direction of the shaft, the mine being arranged completely inside the shaft in the rest position and protruding from a front end of the shaft in the active position. The pen further comprises an actuating element movable perpendicular to the longitudinal direction of the shaft between an active position and a rest position, which is operatively connected to the mine via a connecting element in such a way that the mine upon 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 connecting element being rotatably mounted in a central portion on the shaft, a first end portion of the connecting element on the actuating element and a second end portion of the connecting element being mounted directly or indirectly on the mine, and the connecting element having at least two connecting members includes, which are each hingedly connected to one another.

In other words: the actuating element can be moved vertically upwards and downwards, in relation to a horizontally held pin, that is to say in the radial direction in relation to a central longitudinal axis of the pin, and the mine can be moved horizontally back and forth. The movement of the actuating element and the movement of the mine thus take place in directions perpendicular to one another. The actuating element and the mine are thus coupled in terms of movement via the connecting element, so that when the actuating element is actuated, the mine is displaced or adjusted axially, that is to say along or parallel to a central longitudinal axis of the shaft. The actuating element is arranged in a rear section or end of the shaft so that it is operatively connected to a rear end of the mine and moves it towards a front end of the shaft for movement in the active position.

The active position here is to be understood as the position of the mine or of the actuating element when the pen is in use, that is to say is in the 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 pen is in the non-use state, ie the mine is retracted.

The idea of the present invention thus consists in providing a mechanical pen in which the lead can be moved from its rest position into the active position reliably, repeatably and in a manner that is simple for a user. In other words: a movement of the actuating element that takes place perpendicular to the longitudinal direction is converted into a movement of the mine in the longitudinal direction when it is actuated. The connecting element has the advantage that the distance of the actuating element which it covers when moving from the rest position to the active position can be shorter than the length of movement of the mine in the longitudinal direction required to reach the active position of the mine. In addition, due to the movement of the actuating element perpendicular to the longitudinal direction, compared to known pens in which the actuating element as well as the mine is moved in the longitudinal direction, less space is required within the shaft, so that it can be more compact overall, e.g. shorter or the same Size a longer lead can be used to form a more durable pen.

The connecting element is rotatable in a central section on the shaft, a first end section of the connecting element is on the actuating element and a second end section of the connecting element is mounted directly or indirectly on the mine. The connecting element is thus fixedly and rotatably attached to the shaft about an axis of rotation or rotation that runs both perpendicular to the longitudinal direction of the shaft and perpendicular to the direction of movement of the actuating element, in other words about an axis of rotation that runs in the transverse direction. A middle section of the connecting element thus forms a fulcrum or fixed point around which the connecting element or both the first and second end sections of the connecting element can be rotated, the position of this fixed point relative to the shaft not changing, i.e. relative to the shaft there is no longitudinal movement of the shaft. The first and second end sections of the connecting element are also stationary on the actuating element or attached to the mine, so that the relative position of the first end portion with respect to the actuating element and the relative position of the second end portion with respect to the mine also do not change when moving from the rest position to the active position and vice versa. If the actuating element is moved perpendicular to the longitudinal direction of the shaft, a force is thus exerted on the first end section of the connecting element. As a result, the first end section of the connecting element is also moved perpendicular to the longitudinal direction of the shaft, i.e. carried along by the actuating element, so that this causes a rotation of the connecting element around the fixed point and thus also a movement of the second end section and moves the lead from the rest position to the active position will. In other words: the movement of the actuating element perpendicular to the longitudinal direction of the shaft is converted by the connecting element into a movement of the mine in the longitudinal direction of the shaft. The connecting element thus has the function of a lever.

The connecting element can be a single connecting element or a one-piece connecting element, which thus only comprises a connecting member which is rotatable in a central section on the shaft, with a first end section on the actuating element and with a second end section 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 according to the invention comprises at least two connecting members, that is to say in particular a first connecting member and a second connecting member, which are each connected to one another in an articulated manner. In each case adjacent connecting links are connected to one another in their mutually facing end sections so that they can be pivoted about a pivot axis. The pivot axes, about which two connecting members, for example the first and second connecting members, are pivotably arranged with respect to one another, likewise run 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 a curved line following the rotation about the axis of rotation of the central section of one of the connecting links which is fixed to the shaft. A first connecting member, which is connected to the actuating element, is fixed on the shaft in a stationary rotatable manner about the axis of rotation. The first end portion of the connecting element arranged on the actuating element is thus formed by the first connecting member, the second end portion, which is fixed to the mine, is formed by the second or, depending on the embodiment, a third or further connecting member. Several connecting links have the advantage that, with the movement distance of the actuating element remaining the same, a longer movement distance of the mine in the longitudinal direction can be achieved perpendicular to the longitudinal direction of the shaft.

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, with adjacent connecting links being connected to one another in an articulated manner, that is to say pivotably about a pivot axis.

In the rest position, the actuating element preferably protrudes at least partially from a first side face of the shaft and in the active position at least partially protrudes from a second side face of the shaft opposite the first. In the rest position, the actuating element ends flush with the second side surface of the shaft; in the active position, the actuation element ends flush with the first side surface of the shaft. As a result, a disruptive protrusion of the actuating element is largely avoided. The respective protruding part of the actuating element can be reached for the axial adjustment of the mine, so that the actuating element can be moved from the active position into the rest position and vice versa by pressing the respective protruding portion.

In a further preferred embodiment, the actuating element has a first longitudinal section extending in the longitudinal direction of the shaft and a second longitudinal section extending perpendicular to the longitudinal direction and at least partially arranged within the shaft, at least the first longitudinal section in the rest position from the first side surface of the shaft and the second longitudinal section in the active position with a free end at least partially from the second, the first opposite side surface of the shaft protrudes. In this case, the first longitudinal section forms, for example, a retaining clip in order to be able to store the pen when it is 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 captive insertion of the pin can be formed on the free end of the first longitudinal section. Because the first longitudinal section only protrudes from the side surface of the shaft when the lead is in the rest position, soiling, for example the breast pocket or briefcase, is reliably avoided. The second longitudinal section is at least partially held or guided in a rear region of the shaft and interacts with an inner circumferential surface of the shaft, for example in the sense of a sliding pair.

In a further preferred embodiment, the free end of the second longitudinal section has a smaller width than an adjoining central section of the second longitudinal section, the free end in the rest position and / or in the active position being at least partially arranged within a recess of the shaft . The recess is formed in a section of the shaft that adjoins the second side surface. 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 the latter forms a form fit acting in the longitudinal direction 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, has an inner circumferential surface of the shaft cooperates. This stop surface is arranged, for example, at the free end of the longitudinal section and interacts with an inner circumferential surface delimiting the recess of the shaft in order to prevent the actuation element from moving in the longitudinal direction. In addition, the middle section of the second longitudinal section adjoining the free end can form a stop surface which, in the active position, rests against an inner circumferential surface of the shaft. This makes it clear to the user, for example, that the mine has reached the active position as the end position and prevents the actuating element from being pressed too hard. Another stop surface is formed, for example, by a rear end face of the actuating element facing the rear end of the shaft, which rests on an inner circumferential surface of the rear end of the shaft and is pressed against this during the movement of the actuating element from the rest position into the active position, in order to achieve the completely convert the force resulting from the movement of the actuating element into a rotation of the connecting element. Furthermore, this keeps the mine in the active position and prevents the mine from moving independently back into the rest position.

In order to be able to fix the connecting element or its first end section to the actuating element, the actuating element, in particular the second longitudinal section of the actuating element, in an advantageous embodiment, has a recess in which the first end section of the connecting element is directly or indirectly supported. 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 the recess in such a way that movement in the longitudinal direction of the shaft is prevented so that the connecting element cannot slip out. The recess can be designed, for example, in the form of a hole, so that the connecting element can be fixed within the recess using a pin or bolt.

In an advantageous development, the recess extends from a front end face of the actuating element, in particular from a front end face of the second longitudinal section of the actuating element, starting in the longitudinal direction of the shaft, at least partially into the actuating element, the first end section of the connecting element being movably supported in the recess. The front end face is the end face of the actuating element facing the mine and the front end of the shaft; the recess thus extends perpendicular to the longitudinal direction of the shaft and perpendicular to the direction of movement of the actuating element, i.e. in the transverse direction and in the direction of a rear end of the Shaft. As a result, 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 being movably held in the recess. When the actuating element moves, the first end section of the connecting element is carried along by the latter and thus also moves perpendicular to the longitudinal direction.

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

In a preferred embodiment, the locking and / or latching device is formed by a joint connecting a first and a second connecting member, which joint connects the first and the second connecting member pivotably about a pivot axis. The joint can be moved beyond a dead point for locking when the actuating element is moved from the rest position into 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 a second connecting element on the mine. This creates a self-locking system that prevents the lead from moving independently from the active position to the rest position.

In order to support the movement of the lead from the active position to the rest position after the pen has been used, the pen can, as already mentioned, comprise a restoring element, in particular a spring, which biases the lead in the axial or longitudinal direction in the active position. As soon as the actuating element is moved from the active position to the rest position and the locking or detent position is released, the mine is quasi automatically moved back from the active position to the rest position. For this purpose, the spring is arranged in a front region of the shaft and presses the mine axially in the longitudinal direction towards a rear region 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, which is arranged within the shaft between the lead and the connecting element and is axially adjustable in the longitudinal direction, for guiding the lead. The guide element has a receptacle for receiving a rear end of the mine. The connecting element or a connecting link or a second, front end section of the connecting element or the connecting link is mounted on the guide element and is thus indirectly operatively connected to the mine. The guide element is also always pressed against the connecting element by the restoring element, so that a reliable hold of the connecting element in the guide element is ensured. Such a lead guide has the advantage that tilting or migration of the lead is prevented during the axial adjustment. In a structurally simple variant, the guide element has a sleeve-shaped receiving section for receiving the mine and an adjoining guide section which interacts with an inner circumferential surface of the shaft and slides along it during the axial adjustment and on which the connecting element or the connecting member is supported or is attached. The outer circumferential surface of the guide element is shaped in accordance with the inner circumferential surface of the shaft, that is, for example, has a square 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 a movement of the actuating element and the mine. This reliably prevents transverse movement or tilting of the connecting element and / or the actuating element during actuation.

For example, the pin comprises at least one 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 displaceably mounted within a recess formed on the inner circumferential surface of the shaft. For example, the connecting element is in the axial direction by means of a pin in a recess designed as an elongated hole guided displaceably, so that tilting of the connecting element and migration of the mine can be avoided. As an alternative to this, the connecting element can only be mounted within the guide element, which in turn is supported with an outer circumferential surface on an inside of the shaft or on the actuating element, more precisely on its first longitudinal section.

To guide the actuating element in the shaft during a movement, the pin in a further preferred embodiment has at least one second guide means for guiding the actuating element in the shaft during a movement of the actuating element, which means at least one protruding from an inner circumferential surface of the shaft and perpendicular to the longitudinal direction of the shaft extending projection which cooperates with at least one receptacle formed on a side surface of the actuating element, in particular on a side surface of the second longitudinal section, extending perpendicular to the longitudinal direction in the sense of a sliding pairing. When the actuating element is actuated perpendicular to the longitudinal direction, it is thus guided within the shaft. A direction of movement of the actuating element that deviates from perpendicular to the longitudinal direction is not possible, so that tilting or tilting is reliably prevented.

The receptacle is preferably provided by a protrusion protruding from a side surface of the actuating element, in particular the second longitudinal section, starting perpendicularly to the longitudinal direction from the first longitudinal section and at least partially extending along the side surface, and an end section of the actuating element protruding beyond the side surface with a protrusion formed in particular of the second longitudinal section. The rear end section of the actuating element rests at least partially flat on a rear inner circumferential 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 pen 2 for writing and / or painting purposes with a shaft 4 and a mine 6. The shaft 4 comprises a first elongated shaft part 4a, a second elongated shaft part 4b and a third conical shaft part 4c. The first shaft part 4a and the second shaft part 4b each have at least essentially a U-shaped cross-sectional profile, the open sides of the shaft parts 4a, 4b facing one another in the assembled state. In the assembled state, the second shaft part 4b is arranged within the first shaft part 4a and is held in this, for example, by clamping or additionally glued or fixed by means of a tongue and groove connection. Holding elements 8a are integrally formed on a front end section of the second shaft part 4b and, in the assembled state, engage positively in complementarily designed holding elements 8b of a rear end section of the third shaft part 4c. The first, outer shaft part 4a can be made of wood, for example, in order to give the user a good haptic and visual impression. In principle, the shaft 4 can also be made 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 mine 6 are largely not visible from the outside.

The refill 6, in the present case exemplarily 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 within 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. In the rest position ( Figures 2 to 8 ) the mine 6 is arranged completely within the shaft. In the active position ( Figures 9-14 ) the lead 6 protrudes with its front end, ie part of the writing tip 6c and the writing ball 6b with a protrusion from a front end of the shaft 4 or the shaft part 4c.

At a rear end, the pin 2 has an actuating element 10 which can be moved between a rest position and an active position in a direction of movement B running perpendicular to the longitudinal direction L and which is operatively connected to the mine 6 via a connecting element 12 for the axial adjustment of the mine 6, 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 base body or second longitudinal section 10b which, starting from the first longitudinal section 10a, extends perpendicular to the longitudinal direction L.

Within the shaft 4 between the mine 6 and the connecting element 12, a guide element 14 for guiding the mine 6 is arranged, which is axially adjustable in the longitudinal direction L so that the connecting element 12 is indirectly connected to the mine 8 via the guide element 14. 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 element 14 is designed to be complementary to an inner circumferential surface of the shaft 4 or of the shaft part 4b in order to enable problem-free sliding.

At a front end, the pen 2 has a restoring element, in the present case a spring 16, which surrounds the writing tip 6c in the assembled state and biases the mine 6 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 the reservoir 6a and with a second end 16b on an inner circumferential surface of the conical shaft part 4c, in particular on a stop surface formed on the inner circumferential surface. In the active position, the spring 16 is pretensioned, that is to say compressed, in the rest position, the spring 16 is relaxed. The guide element 14 is always pressed by the spring 16 in the direction of the rear end of the pin 2 and thus against the connecting element 12, so that fastening of the connecting element 12 in or on the guide element 14 is not absolutely necessary.

According to the exemplary embodiment, the connecting element 12 comprises a first connecting member 12a and a second connecting element 12b, which are connected to one another so as to be pivotable about a pivot axis S. The first connecting member 12a comprises two plate-shaped elements which are arranged parallel to one another and which are connected at two opposite end sections 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 exemplary embodiment the first connecting member 12a, is mounted in a central section 26a so as to be rotatable about an axis of rotation 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 this case a cylindrical pin, is inserted, which in turn is mounted in a recess 32 of the shaft 4 or of 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 its second longitudinal portion 10b, a second end portion 28a of the connecting element 12 or the second connecting member 12b is fastened to the guide element 14, that is to say is supported indirectly on the mine 6. The mutually facing end sections 26c, 28b of the first connecting link 12a and of the second connecting link 12b are connected pivotably via the joint 22.

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

To guide the actuating element 10 in the shaft 4 or 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 projection 50 protruding from an inner circumferential surface 48 of the shaft 4 or of the second shaft part 4b and extending perpendicular to the longitudinal direction L of the shaft 4 10b formed, perpendicular to the longitudinal direction L and, in the assembled state, parallel to the projection 50 extending receptacle. When the actuating element moves 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 formed by a protrusion 56 protruding from the side surface 52 of the actuating element 10 or its second longitudinal section 10b, perpendicular to the longitudinal direction L from the first longitudinal section 10a and extending to a free end 49 of the second longitudinal section 10b and an end section 58 of the actuating element 10 or the second longitudinal section 10b thereof protruding beyond the side surface 52 in the direction of a rear end of the shaft.

In the Figures 2 to 8 the pen 2 is shown in different views while it is in the non-use state, both the mine 6 and the actuating element 10 are thus in the rest position. The mine 6 is arranged completely within the shaft 4 in the rest position. The actuating element 10 protrudes partially in the rest position, namely with its first longitudinal section 10a and part of the second longitudinal section 10b with an overhang 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 Fig. 2 , in which the pin 2 is shown without the outer, first shaft part 4a for a better illustration of the guide means 36, arranged in the rest position at a rear end of the recess 38. Fig. 3 shows a pin 2 with an outer first shaft part 4a, which covers the guide means 36 and consists, for example, of wood or plastic.

the Figures 4 and 5 each show a longitudinal section along the line IV-IV according to FIG Fig. 2 or the line VV according to Fig. 3 , Fig. 6 shows a detailed view of a rear section of the pin 2. Both the actuating element 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 almost parallel to the actuating element 10 in the rest position. A first end section 26b of the first connecting member 12a is mounted in a recess 62 of the actuating element 10 or of the second longitudinal section 10b of the actuating element 10. The recess 62 extends from a front end face 64 of the actuating element 10 or of the second longitudinal section 10b of the actuating element 10 in the longitudinal direction of the shaft partially into the actuating element 10. The connecting element 12 or the first connecting member 12a is movably supported in the recess 62 by the cylindrical web 20 arranged in the recess 62. If the actuating element 10 is moved perpendicular to the longitudinal direction L of the shaft in the direction of movement B, the first end section 26b of the connecting element 12 or the first connecting member 12a is carried along by the actuating element 10 and thus also moved perpendicular to the longitudinal direction L of the shaft. This causes a rotation of the connecting element 12 or the first connecting member 12a about the axis of rotation D or about the fixed point F at which the connecting element is fixedly but rotatably mounted on the shaft 4. The second end section of the first connecting member 12a is thereby moved both in the longitudinal direction L of the shaft 4 and upwards, i.e. perpendicular to the longitudinal direction L of the shaft 4 and thereby pushes the second connecting member 12b connected to it via the joint 22 and thus the mine 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 than a width B _{2 of} an adjoining central section 66 of the second longitudinal section 10b. The free end 49 is also partially arranged in a recess 68 of the shaft 4 in the rest position in order to avoid tilting or blocking of the actuating element 10 at the beginning of the movement.

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

In the Figures 8 to 13 the pen 2 is shown in different views while it is in the use state or in the writing position, both the mine 6 and the actuating element 10 are thus in the active position. In the active position, the second longitudinal section 10b of the actuating element 10 protrudes partially with a free end 49 from a second side surface 60b of the shaft 4, which is opposite the first side surface 60a of the shaft with an overhang A ₂ . The lead 6 protrudes from the front end of the shaft 4 with a protrusion C.

The free end 49 of the second longitudinal section 10b of the actuating element 10 has a smaller width B ₁ than an adjoining 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 protrudes beyond the second side surface 60b. In order to move the mine 6 from the active position back into the rest position, the locking device can be released by pressing the free end 49 of the actuating element and the mine 6 is opened by rotating the connecting element 12 or the connecting member 12a with the aid of the spring 16, which is biased in the active position, moved back into the rest position.

As in particular in the detailed view in Fig. 12 As can be seen, the actuating element 10 has a stop surface 70 which, in the active position, rests against the inner circumferential surface 48 of the shaft 4 and prevents further movement of the actuating element 10 and signals to the user that the end position has been reached. The stop surface 70 is formed by a lower side surface 72 of the central section 66 of the second longitudinal section 10b of the actuating element 10.

Fig. 15 shows an exploded view of a further embodiment of the pen 2 for writing and / or painting purposes, which essentially has the features according to the above-described pen 2, so that reference is predominantly made to it. Corresponding features are marked with identical reference symbols. The pin 2 comprises a shaft 4 with a first one elongated shaft part 4a, a second elongated shaft part 4b, a third conical shaft part 4c and a fourth shaft part 4d, which in the present case serves in particular to connect the second shaft part 4b to the third shaft part 4c. The refill 6, again exemplarily 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 within 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 mine 6 is arranged completely within the shaft, in the active position the front end of the mine 6 protrudes with a protrusion from a front end of the shaft 4 or the shaft part 4c. A restoring element or a spring 16 in turn pretensions the mine 6 in the active position in a longitudinal direction L of the shaft 4.

At a rear end, the pin 2 in turn has an actuating element 10 with a first longitudinal section 10a and a second longitudinal section 10b which can be moved in a direction of movement B running perpendicular to the longitudinal direction L between a rest position and an active position, which is used for the axial adjustment of the mine 6 with this via a Connecting element 12 is operatively connected so that the mine can be adjusted axially in the longitudinal direction of the shaft when the actuating element 10 is moved perpendicular to the longitudinal direction of the shaft between the rest position and the active position.

The difference from that in the Figures 1 to 14 described pin is now in the design of the guide element 14 or 114 and the connecting element 12 or 112. The guide element 114 is arranged within the shaft 4 between the mine 6 and the connecting element 112, and axially adjustable in the longitudinal direction L, so that the connecting element 112 is indirectly connected to the mine 8 via the guide element 114. The guide element 114 has a receptacle 114a for receiving a rear end of the mine 6. Part of an outer circumferential surface 114b of the guide element 114 is complementary to an inner circumferential surface of the shaft 4 or of the shaft part 4b in order to enable problem-free sliding.

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

The connecting element 112, according to the exemplary embodiment the first connecting member 112a, is mounted in a central section 126a so as to be rotatable about an axis of rotation 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 this case a cylindrical pin, is inserted, which in turn is mounted in a recess 132 of the shaft 4 or of 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 on its second longitudinal section 10b, a second end portion 128a of the connecting element 12 or the second connecting member 112b is attached to the guide element 14, i.e. indirectly to the Mine 6 stored. The mutually facing end sections 126c, 128b of the first connecting link 112a and of the second connecting link 112b are connected pivotably via the joint 122.

To guide the connecting element 112, the pin 2 has guide means 136 according to an alternative variant. According to the present exemplary embodiment, the guide means 136 comprises a connecting element 140 (shown in dashed lines), likewise, for example, a cylindrical pin, which is mounted within the guide element 114 or attached to it.

In this case, instead of the through-hole, a recess 142 is provided on the second end section 128a of the connecting element 112 or the connecting member 112b, which engages around the connecting element 140 fixed within the guide element 114 in such a way that the connecting element 112 moves in the axial direction within the guide element 114 is held.

In the Fig. 16 (Rest position) and 17 (active position) a section of a rear end section of a pin 2 (not explicitly shown) is shown in which the connecting element 212 comprises only a first, that is, a single connecting member, so that the connecting element 212 is formed in one piece. If the mine does not have to cover a long distance, that is to say no such large translation is required, such a configuration offers the advantage that material can be saved.

The connecting element 212 is mounted on the shaft 4 so as to be rotatable about an axis of rotation D. With a first end section 226b, the connecting element 212 is mounted in a recess 62 which extends into the actuating element 10 from a front end face 64 of the latter. A front end section 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 essentially in the longitudinal direction L of the shaft 4, ie the front end section 226b and the rear end section 226c are arranged one behind the other in the longitudinal direction. By actuating the actuating element 10, the connecting element 212 is rotated about the axis of rotation so far that a restoring force of the restoring element pressing the guide element 14 against the front end section 226c of the connecting element 212 is not sufficient to cause the connecting element 212 to rotate back. As a result, the mine 6 is locked in the active position. Only a movement of the actuating element from the active position into the rest position causes a rotation of the connecting element 212 and thus a release of the lock. In the rest position, the connecting element 212 lies flat on a rear end face 214 of the guide element 214 and extends essentially transversely to the longitudinal direction L of the shaft 4, ie the front end section 226b and the rear end section 226c are arranged next to one another in the transverse direction.

Further components of the pin 2 of the exemplary embodiment according to FIG Fig. 16 and 17th correspond to those of the exemplary embodiment with a connecting element 12 having two connecting members 12a, 12b, so that these are provided with the same reference symbols and reference is made to the above statements in this regard.
