Description

Technical field

[0001] The present disclosure relates to a system comprising a writing instrument and its storage. In particular, the present disclosure relates to a system comprising a writing instrument, such as a pen or marker, a pen holder, and a sleeve to optimize the handling and storage of the writing instrument. background

[0002] In the realm of writing instruments, it is widely known that the market offers a multitude of solutions to meet the diverse needs of users. Common systems typically include writing instruments in the form of pens and markers, along with corresponding storage containers. These writing instruments are usually designed to accommodate a specific type of refill, individually tailored for various uses such as writing, drawing, or marking. Such writing instruments often feature a casing that encloses either the refill or a writing tip to protect it from damage. Furthermore, many writing instruments are equipped with mechanisms that allow the refill to be extended and retracted, controlling the writing process and protecting the refill when not in use.

[0003] Common pen holders are typically cylindrical containers that serve as protective and transport cases for writing instruments. These holders provide space for the writing instrument and allow the user to easily insert and remove it. Usually, the holders are designed to securely fix the writing instrument and protect it from accidental drops, while still ensuring easy access. Modern pen holders may also have additional features, such as clips for attaching them to clothing or built-in sharpeners for sharpening the pen's lead.

[0004] Despite considerable advances in writing instruments and their storage systems, challenges remain that existing systems do not fully address. For example, there is a continuing need for improved mechanisms to protect and secure the refill and writing tip, as well as for systems that allow for more efficient and flexible use of writing instruments. Particularly in applications requiring special features such as deep-hole marking or differentiated writing positions, available solutions are often inadequate or cumbersome to use.

[0005] German patent application DE 20 2021 103 608 U1 discloses a writing instrument in the form of a deep-hole marker with a pointed, sleeve-shaped housing section, which is detachably connected to another housing section via a thread. The writing instrument is designed as a mechanical pencil and can be used as a normal mechanical pencil when the pointed housing section is screwed on. When the pointed housing section is unscrewed, the writing instrument can be used as a deep-hole marker.

[0006] A disadvantage of this solution is that the sleeve-shaped housing section must be unscrewed from the writing instrument by the user using both hands to switch from the mechanical pencil function / configuration to the deep-hole marker function / configuration. This is impractical and undesirable in everyday construction site use. Furthermore, the sleeve-shaped housing section, which is detachably connected to the main housing section via a thread, increases the risk of losing it. Brief description of the Revelation

[0007] The purpose of this disclosure is therefore to eliminate or at least reduce the disadvantages of the prior art. Specifically, the purpose of this disclosure is to provide a system that combines the functionality of a conventional writing instrument with that of a deep-hole marker, and in which switching between the individual functionalities is simple, quick, and preferably possible with one hand. Furthermore, the purpose of this disclosure is to minimize the risk of losing parts of the system and to protect the writing instrument from damage.

[0008] These tasks are solved by a system according to claim 1. Furthermore, additional advantageous embodiments result from the dependent claims and the following description.

[0009] Specifically, the task is solved by a system, in particular a writing instrument holder system, comprising a writing instrument, in particular a pen or marker, a pen holder for storing the writing instrument, and a sleeve. The writing instrument has a refill holder designed and configured to receive and secure a writing refill, the refill holder being connected to or formed with a writing tip formed at one end of the refill holder. The writing instrument further includes a housing that at least partially surrounds the refill holder or is attached / coupled to it.

[0010] The pen holder has a base body, preferably sleeve-shaped, which extends longitudinally and defines a receiving space for at least partial reception of the writing instrument. The base body has a wall at one end along its longitudinal axis for inserting the writing instrument into the receiving space. The sleeve is coupled to the writing instrument in a writing position, where it radially surrounds the lead holder and the writing tip is exposed, and in a deep-hole marking position, where the writing tip is exposed and the lead holder is at least partially exposed.

[0011] In other words, the system consists of the writing instrument, preferably a pen or marker, for example a mechanical pencil, a paint marker, a felt-tip pen or the like, the pen holder for storing the writing instrument and the sleeve, which can assume different positions to implement different configurations of the system or the writing instrument, namely specifically a writing configuration and a deep-hole marking position.

[0012] The writing instrument has a refill holder designed and configured to receive and secure a writing refill, and a writing tip connected to or formed with the refill holder. The body at least partially surrounds or is attached to the refill holder and forms the basic body of the writing instrument.

[0013] The pen holder comprises the main body, which extends lengthwise and defines the compartment for at least partially holding the writing instrument. The main body has an insertion opening at one end through which the writing instrument can be inserted into the compartment.

[0014] The sleeve of the system can be positioned for writing, where it is fixed to the writing instrument and radially surrounds the refill holder, essentially exposing the writing tip, thus enabling normal writing with the instrument. Preferably, the sleeve is ergonomically adapted to the fingers in a writing position. In other words, in the writing position, the sleeve forms a grip section.

[0015] Furthermore, the sleeve can be moved into the deep-hole marking position, in which both the writing tip and part of the lead holder are exposed, thus enabling writing operations, particularly marking operations, into hard-to-reach areas. In the deep-hole marking position, the sleeve is coupled to the pen holder.

[0016] Thus, a key technical advantage of the sleeve is its ability to switch between different positions, which significantly increases the functionality of the writing instrument by allowing not only writing under normal conditions, but also marking in deep or hard-to-reach holes.

[0017] This configuration ensures that the system is both user-friendly and practical, flexibly and reliably meeting various writing requirements. The pen holder also provides secure storage for the writing instrument, extending the lifespan of the refills and nibs, improving the system's portability, and ensuring the sleeve is securely stored in the deep-hole marking position.

[0018] The reversible coupling of the sleeve to the pen holder in the deep-hole marking position allows the writing instrument to be removed from the pen holder with one hand in this position. Furthermore, the reversible coupling of the sleeve to the writing instrument in the writing position allows the writing instrument to be removed from the pen holder with one hand in this position.

[0019] The writing instrument, particularly in the form of a pen or marker, serves as the central element of the system. It represents the tool for writing and is designed to meet the requirements of various writing and marking situations.

[0020] The pen holder is designed and constructed to safely store the writing instrument when not in use. This holder protects the writing instrument from damage and allows for tidy storage when not in use, as well as easy access to the writing instrument.

[0021] The sleeve is part of the system and fulfills the function of making the writing instrument usable as both a conventional writing pen and a deep-hole marker by selectively coupling / being able to couple the sleeve to both the pen holder and the writing instrument.

[0022] The writing instrument features a refill holder designed and configured to securely hold and fix a standard writing refill. This holder is essential as it stabilizes the refill and enables an efficient writing process.

[0023] The lead holder is preferably directly or indirectly connected to the writing tip, or the writing tip is formed directly on the lead holder. This means that the writing process is directly supported by the lead holder without the need for additional connections or structural supports. In other words, the lead holder forms a structurally load-bearing element of the writing instrument.

[0024] The casing surrounds the lead holder, at least partially, or is directly attached to it. This casing provides structural protection, for example, for a lead advance mechanism, while simultaneously allowing for easier handling and a secure grip on the writing instrument. Preferably, the casing can be ergonomically designed, at least in part.

[0025] The pen holder essentially consists of a base body, preferably shaped like a sleeve. This shape allows for an efficiently manufactured structure that offers both stability and ease of use. The base body of the pen holder extends lengthwise, which makes it easy and secure to hold the writing instrument.

[0026] Within the base body is a receiving chamber designed to at least partially hold the writing instrument. This receiving chamber protects the writing instrument during storage. In a preferred embodiment, the receiving chamber can be sealed airtight from the surrounding environment when a writing instrument is inserted. Embodiments are also conceivable in which the base body wall can be designed with openings, for example, in the form of holes or slots. These openings can function as drainage holes. The base body wall of the pen holder defines the structure of the base body. It provides the stability and strength necessary to securely hold and protect the writing instrument.

[0027] At one end of the longitudinal direction, preferably in an end face of the base body, the insertion opening is located in the base body wall. This opening serves to insert the writing instrument into the receiving chamber and enables easy handling. Preferably, the insertion opening can be the only opening of the receiving chamber to the surrounding environment.

[0028] The sleeve is coupled to the writing instrument in the writing position. In this position, the sleeve radially surrounds the refill holder, while the writing tip remains exposed, allowing for comfortable writing. In the writing position, the writing instrument can essentially function and be used like a conventional pen or marker.

[0029] In the deep-hole marking position, the sleeve is coupled to the pen holder. In other words, the sleeve is no longer fixed to the writing instrument itself, but is held and stored in the pen holder. In this position, the writing tip is exposed, and the lead holder is at least partially accessible, which facilitates specific marking processes, especially deep-hole marking.

[0030] The core of the invention is therefore that, in the writing position, the sleeve is part of the writing instrument and enables the writing instrument to be used as a conventional pen or marker, and that, in the deep-hole marking position, the sleeve is part of the pen holder and enables the writing instrument to be used as a deep-hole marker. In other words, the core of the invention is that the sleeve can be reversibly coupled / connected to either the writing instrument and / or the pen holder.

[0031] According to a preferred embodiment, the sleeve can have a first locking geometry which is provided and designed to lock reversibly with the writing instrument, preferably with the housing of the writing instrument, by force and / or form locking.

[0032] In other words, the first locking geometry can be specifically designed and configured to ensure a frictional or form-fit reversible locking of the sleeve to the writing instrument. This means that the first locking geometry enables a mechanical connection that holds the sleeve securely and stably to the writing instrument, while simultaneously allowing easy disassembly and reassembly without permanently deforming or damaging the components. A frictional fastening method utilizes the mechanical resistance created by the existing frictional forces between the connected parts.

[0033] In addition to or as an alternative to friction-based locking, the locking geometry can also be designed to form a positive-locking, reversible connection with the writing instrument. This means that the connection is created by matching and complementary features in the mating components. Examples of such features include interlocking cams and corresponding recesses, locking hooks, bayonet fittings, locking pins / balls, or similar devices. These mechanisms ensure a reliable fixation that can withstand the mechanical shocks and vibrations commonly encountered on construction sites.

[0034] The first locking geometry is particularly advantageous, as it is adapted to create a force-fit and / or form-fit reversible locking connection with the writing instrument's housing itself. Such a design enables flexible and secure handling, since a substantially closed overall contour of the writing instrument can be achieved in the writing position, which essentially corresponds to that of a conventional pen.

[0035] The reversible locking mechanism ensures good usability, especially one-handed operation and low maintenance of the system, as the components can be easily separated and reassembled without the need for special mechanisms or even tools, thus increasing the overall functionality of the system.

[0036] The optionally combined locking mechanisms, consisting of force-locking and / or form-locking components, offer a robust yet user-friendly solution that facilitates handling of the writing instrument, particularly by enabling quick and reliable switching between the writing and deep-hole marking positions, while simultaneously ensuring its structural integrity. Such a locking mechanism not only improves the efficiency and reliability of use but also significantly contributes to user satisfaction by enabling simple, intuitive, efficient, and repeatable operation of the system on construction sites.

[0037] In another aspect, the writing instrument may have a first receiving geometry which is designed and configured to lock into the first locking geometry.

[0038] In other words, the writing instrument can incorporate or (partially) form the initial receiving geometry. Specifically, this means that the initial receiving geometry is functionally designed to securely fix the sleeve onto the writing instrument. Specifically, the initial receiving geometry can be designed and configured to engage with a corresponding initial locking geometry of the sleeve, thus implementing and ensuring secure fixation. This improves the structural integrity of the system and ensures a stable and secure connection between the components of the writing instrument and the sleeve.

[0039] The locking connection between the first receiving geometry and the first locking geometry enables precise positioning and fixing of the sleeve and the writing instrument to each other, preventing both an unintentional detachment of the writing instrument from the sleeve and simultaneously allowing for easy, targeted release of the locking connection between the first receiving geometry and the first locking geometry, thus simplifying the operation and handling of the system overall.

[0040] The first locking geometry and the first receptacle geometry can be geometrically aligned. This mechanical connection not only contributes to the overall system's stability in the writing position but also optimizes usability by ensuring that the writing tip and receptacle are always correctly positioned for writing and preventing the cartridge from unintentionally detaching from the writing instrument during use.

[0041] The defined detent mechanism allows the system to switch easily and seamlessly between different operating modes – writing position and deep-hole marking position – without additional adjustments or corrections, significantly improving the system's functionality and ease of use. Furthermore, the detent geometry increases the overall system's durability and longevity, as the targeted distribution of forces and the reversible locking of components ensure even stress distribution and reduced wear.

[0042] In another aspect, the sleeve can have a second locking geometry which is designed and configured to lock reversibly with the pin holder, preferably in the receiving space of the pin holder, by force and / or form locking.

[0043] This design offers additional functionalities and advantages. First, the second locking mechanism on the sleeve ensures a secure and stable connection between the sleeve and the pin holder, fixing the sleeve in the deep-hole marking position within the pin holder without the need for a separate fastener. This simplifies the system's design, as integrating the locking mechanisms optimizes both manufacturing processes and user handling.

[0044] In practice, this means that the sleeve is detached from the writing instrument in the deep-hole marking position and remains in the pen holder, where it is securely stored. Specifically, the force-fit and / or form-fit locking mechanism holds the sleeve firmly in the pen holder's receptacle, minimizing the risk of accidental loss or damage when using the writing instrument as a deep-hole marker. Furthermore, this locking mechanism facilitates automatic and intuitive handling: the user can simply pull the writing instrument out of the pen holder in the deep-hole marking position, causing the sleeve to detach and remain in the pen holder. The form-fit contact, achieved, for example, through special grooves or recesses, also ensures precise alignment of the parts.This precise alignment ensures that the writing instrument is always inserted into the pen holder in the optimal position, thus improving the locking mechanism. The reversible nature of this locking geometry also allows for repeated use without material fatigue or loss of function over time, enhancing the long-term reliability and durability of the system.

[0045] According to another embodiment, the pen holder has a second receiving geometry, which is preferably arranged on an end section facing away from the insertion opening.

[0046] In other words, the pen holder can have the second receiving geometry in or at the closed tip of the pen holder.

[0047] This placement of the receptacle geometry at the opposite end of the pen holder optimizes the functionality and handling of both the writing instrument and the holder, as it provides a securing or locking mechanism through interaction with the second locking geometry and reduces the risk of damage to the receptacle geometry. The second receptacle geometry is specifically designed and configured to engage with the corresponding second locking geometry, meaning it may include a grid or mechanical locking component that enables a firm coupling with the matching structure. This creates a more stable connection when using the writing instrument or the sleeve during storage in the pen holder.

[0048] In another aspect, a spring-loaded detent can be formed between the first or second receiving geometry and the first or second detent geometry.

[0049] In other words, a spring-loaded detent can be formed between the first detent geometry and the first receiving geometry. Alternatively or additionally, a spring-loaded detent can be formed between the second detent geometry and the second receiving geometry. A spring-loaded detent means that the receiving geometry and / or the detent geometry has or is a spring element and reversibly engages with its respective counterpart.

[0050] The spring-loaded latch can preferably be designed with a predetermined spring force or exhibit the predetermined spring force. In other words, the latch can be designed such that it releases when a predetermined minimum force is exceeded.

[0051] Alternatively or additionally, a bayonet fitting, a coarse thread, a switchable hook or latch or pin or the like can be formed between the first locking geometry and the first receiving geometry or between the second locking geometry and the second receiving geometry.

[0052] In another aspect, the sleeve in the deep hole marking position can preferably be completely enclosed in the receiving space.

[0053] In other words, the sleeve can be completely, that is, without protrusion, received in the receiving space of the pen holder limited by the base body wall in the deep hole marking position, i.e., in the position in which the sleeve is separated from the writing instrument and coupled to the pen holder.

[0054] Preferably, a first central fiber of the sleeve can be arranged on a second central fiber of the pin holder in the deep-hole marking position. The first central fiber and the second central fiber extend longitudinally in the deep-hole marking position.

[0055] In another aspect, it is possible to switch between the writing position and the deep-hole marking position when the writing instrument is inserted in the pen holder using a switching unit.

[0056] In other words, the switching unit can be configured to switch between the writing position and the deep-hole marking position in the inserted state, that is, in a state in which the writing instrument is held in the pen holder. Preferably, the switching unit can be configured to switchably open and close, or actuate, the detent between the first receiving geometry and the first detent geometry and / or between the second receiving geometry and the second detent geometry.

[0057] In another aspect, the switching unit can be switched by rotating the writing instrument around a longitudinal axis extending in the longitudinal direction.

[0058] In other words, the switching unit can be a rotary switching unit. The switching unit can be designed and configured to switch between the deep-hole marking position and the writing position by rotating the writing instrument around a third central fiber of the writing instrument, which extends longitudinally. Preferably, the rotation can be less than 180°. Particularly preferably, the rotation is 90° or less.

[0059] In other words, the switching unit can be designed and configured to selectively release or engage the detent between the first receiving geometry and the first detent geometry, or between the second receiving geometry and the second detent geometry, by means of rotation. For example, the switching unit can be designed as a ramp, a wedge, a channel, a detent recess, or the like.

[0060] In another aspect, the switching unit may include a feedback element which is designed and configured to give a user haptic and / or acoustic and / or visual feedback when the switching takes place.

[0061] In other words, the switching unit can include the feedback element or be designed as a feedback element that provides feedback during the switching process, i.e., when switching from the writing position to the deep-hole marking position. The feedback can be haptic, audible, and / or visual. For example, it can be a click, a detent, and / or a visual indication. Preferably, the feedback is designed so that the operator knows, without looking, in which configuration they are removing the writing instrument from the pen holder.

[0062] In another aspect, the switching unit can be designed as a rocker arm and / or a sliding lever / a sliding element, or may have the rocker arm and / or the sliding lever / a sliding element.

[0063] Alternatively or additionally, the switching unit can be designed as a rotary knob or have a rotary knob.

[0064] Alternatively or additionally, the switching unit can include a ramp section which is designed and configured to release the locking mechanism, preferably by a rotary movement.

[0065] In another aspect, the mine receptacle can be made of metal.

[0066] In another aspect, the housing can be made of plastic.

[0067] In another aspect, the first locking geometry can be designed as a positive-locking ball locking mechanism.

[0068] In another aspect, the first detent geometry can be designed as a radially circumferential spring element.

[0069] In another aspect, the first detent geometry can be designed as a coarse thread, preferably with less than one screw turn.

[0070] In another aspect, the second locking geometry can be designed as a wedge-shaped locking mechanism.

[0071] Alternatively, the second detent geometry can be designed as a (radially) sequentially formed switching ring.

[0072] Alternatively, the second locking geometry can be designed as spring elements that clamp against the base body wall of the pen holder.

[0073] In another aspect, the sleeve can be made of plastic in one piece.

[0074] In another aspect, the first locking geometry and / or the second locking geometry can be formed as a single piece of material or as a section of the sleeve.

[0075] In another aspect, the first receiving geometry can be formed as a single piece of material or as a section of the housing of the writing instrument.

[0076] In another aspect, the second receiving geometry can be formed as a single piece of material or as a section of the pen holder.

Description of the exemplary implementations

[0077] The following are examples of embodiments of the present disclosure based on the accompanying figures.

[0078] Fig. 1 and Fig. Figure 2 shows a system 2 according to revelation, which includes a writing instrument 4, a pen holder 6 and a sleeve 8 (see Fig. 2) includes a deep-hole marking position. The writing instrument 4, in the first embodiment shown here, is designed as a mechanical pencil. Of course, other forms of the writing instrument 4, such as a paint marker, a felt-tip marker, a ballpoint pen, or the like, are also conceivable. The writing instrument 4 includes a tubular lead holder 10, which is designed and configured to receive, store, and guide a writing lead (not shown).

[0079] A writing tip 14 is formed at a first end section 12 of the lead holder 10, which is simultaneously an end section of the writing instrument 4. The writing tip 14 forms the section of the writing instrument 4 or the lead holder 10 where the writing lead contained in the lead holder 10 is exposed, allowing the writing instrument 4 to be used for writing, drawing, and / or marking. The lead holder 10 and the writing tip 14 can be formed monolithically from metal, as shown in the first embodiment. Alternatively, multi-part embodiments are conceivable. Furthermore, the lead holder 10 and / or the writing tip 14 can be formed from other suitable materials, such as plastic, ceramic, or the like.

[0080] The refill holder 10 is partially enclosed in or fixed to a housing 16 of the writing instrument 4. The housing 16 is a substantially cylindrical or tubular body designed and intended to be gripped by a user. The housing 16 is preferably monolithic, made of plastic or metal, but can also be multi-part. A second end section 18, which is oriented longitudinally L away from the first end section 12, has an actuating button 20 that advances the writing refill in the refill holder 10 via a refill advance mechanism. The refill advance mechanism is enclosed in the housing 16. Radial projections or shoulders in the form of at least one grip element 22 are formed on the housing 16. The grip element 22 is designed and intended to be gripped by the user.

[0081] The pen holder 6 comprises a substantially sleeve-shaped base body 24, which extends in the longitudinal direction L and defines a receiving space 26 for at least partially receiving the writing instrument 4. The base body 24 has a base wall 28, which features an insertion opening 30 at one end along its longitudinal axis. The insertion opening 30 allows the writing instrument 4 to be inserted into the receiving space 26. A fastening clip 32 for securing the system to the user is formed radially on the outer surface of the base body wall 28, i.e., facing away from the receiving space 26. The pen holder 6 is preferably made monolithically of plastic. Multi-part embodiments and embodiments made of other materials, such as metal, ceramic, or composite materials, are also conceivable.

[0082] In the Fig. 1 and Fig. In the deep-hole marking position shown in Figure 2, the writing tip 14 and the refill holder 10 are at least partially exposed. The term "at least partially exposed" means that sections of the writing tip 14 and the refill holder 10 which are not radially enclosed by the housing 16 of the writing instrument 4 are exposed radially to the surrounding environment of the system 2, i.e., they are not shielded. The deep-hole marking position, due to the slim design of the writing tip 14 and the refill holder 10, enables marking in hard-to-reach and deep-lying positions.

[0083] The sleeve 8 is an essentially tubular element designed and configured to reversibly / switchably / selectively enclose the lead holder 10 radially and to be reversibly / switchably / selectively received in the receiving space 26 of the pen holder 6. The sleeve 8 has a first locking geometry 34 designed and configured to reversibly lock onto the housing 16 of the writing instrument 4.

[0084] In the Fig. 1 and Fig. In the first embodiment shown in Figure 2, the first detent geometry 34 is designed as a positive-locking ball detent. Specifically, the first detent geometry 34 of the sleeve 8 comprises spherical partial spheres 34a, which extend radially inwards on spring elements 36. The partial spheres 34a of the detent geometry 34 of the sleeve 8 are designed and configured to engage and detent in spherical recesses 38a formed in the housing 16. The spherical recesses 38a form a first receiving geometry 38 of the first embodiment. The sleeve 8 has a second detent geometry 40 at an end facing away from the first detent geometry 34 in the longitudinal direction L. The second detent geometry 40 is designed to reversibly connect the sleeve 8 to the pin holder 6.

[0085] The second locking geometry 40 is designed as a wedge-shaped locking element 40 in the first embodiment. Specifically, wedge-shaped recesses 42a are formed in the receiving chamber 26 of the pin holder 6 at an end facing away from the insertion opening 30. These wedge-shaped recesses 42a form a second receiving geometry 42 of the first embodiment. The wedge-shaped recesses 42a are designed and configured to engage forcefully with trapezoidal elements 44 of the second locking geometry 40 of the first embodiment. Specifically, each trapezoidal element 44 of the sleeve 8 is reversibly locked / wedged into a wedge-shaped recess 42a of the second locking geometry 40.

[0086] In the deep hole marking position, which is in Fig. 1 and in Fig. As shown in Figure 2, the sleeve 8 is received in the receiving space 26 of the pen holder 6. In other words, the first locking geometry 34 is not engaged with the first receiving geometry 38, i.e., not locked, and the second locking geometry 40 is engaged with the second receiving geometry 42, i.e., in the first embodiment, positively connected. The writing instrument 4 can thus be used as a deep-hole marker, and the sleeve 8 is securely received and fixed in the receiving space 26 of the pen holder 6.

[0087] Fig. Figure 3 shows the system 2 of the first embodiment in a writing position. In the writing position, the sleeve 8 is coupled / connected to the writing instrument 4. In other words, the first locking geometry 34 is engaged with the first receiving geometry 38, i.e., locked in place, and the second locking geometry 40 is not locked with the second receiving geometry 42. The sleeve 8 surrounds the lead receptacle 10 radially such that essentially only the writing tip 14 is exposed. In the writing position, the sleeve 8 forms a kind of grip section by which the writing instrument 4 can be held like a conventional pen.

[0088] In system 2 of the first embodiment, switching between the writing position and the deep-hole marking position is possible by means of a (slight) rotation of the writing instrument 4 in the pen holder 6 about the longitudinal axis of the writing instrument. The switching rotation in the first embodiment is less than 90°.

[0089] Specifically, system 2 has a switching unit 46 in the form of ramp sections 46a. When system 2 of the first embodiment is in the inserted state, i.e., when the sleeve 8 is engaged with both the first detent geometry 34 in the first receiving geometry 38 and the second detent geometry 40 with the second receiving geometry 42, the spring bar 36 can slide off the ramp section 46a of the switching unit 46 by rotating the writing instrument 4 about a central fiber M of the writing instrument 4 or the pen holder 6. This disengages the spherical sub-spheres from the spherical recesses 38a, thus releasing the first detent geometry 34 from the first receiving geometry 38 and allowing the writing instrument 4 to be withdrawn from the pen holder 6 in the deep-hole marking position or deep-hole marking configuration.If, when withdrawing the writing instrument 4 from the pen holder 6, the rotation of the writing instrument 4 around the central fiber is omitted, the writing instrument 4 is withdrawn from the pen holder 6 in the writing position or writing configuration, since the positive locking of the first locking geometry 34 in the first receiving geometry 38 does not release when subjected to a force in the direction of the (negative) longitudinal extension L, while the frictional locking of the second locking geometry 40 with the second receiving geometry 42 releases from a defined release force.

[0090] Fig. 4 and Fig. Figure 5 shows the system as disclosed, according to a second embodiment. The following discussion focuses solely on the differences from the first embodiment and omits a re-description of identical elements.

[0091] In the second embodiment, the first locking geometry 34 of the sleeve 8 is designed as a radially circumferential spring element 34b, which can engage in the first receiving geometry 38 of the writing instrument 4. In the second embodiment, the first receiving geometry 38 is designed as a radially circumferential groove 38a, wherein the radially circumferential groove 38a is inclined towards the refill receptacle 10. The first locking geometry 34 and the first receiving geometry 38 of the second embodiment are pre-tensioned relative to each other by a predefined spring force, such that the predefined spring force must be overcome to release the first locking geometry 34 from the first receiving geometry 38 of the second embodiment.

[0092] In the second embodiment, the second detent geometry 40 is designed as a radially sequentially arranged switching ring 40a. In other words, in the second embodiment, the second detent geometry 40 is designed as an annular shoulder 40b on the sleeve 8, wherein the annular shoulder 40b has sequentially arranged retaining edges 41a and inclined surfaces 41b.

[0093] In the second embodiment, the second receiving geometry 42 is implemented as hooks 50 formed on rod springs 48, which engage in the switching ring 40a. When the hook 50 engages the retaining edge 41a, the second detent geometry 40 and the second receiving geometry 42 of the second embodiment are engaged. However, when the hook 50 is in alignment with the inclined surface 41b, the second detent geometry 40 is not engaged with the second receiving geometry of the second embodiment.

[0094] By rotating the writing instrument 4 of the second embodiment, it is possible to switch between a position in which the hooks 50 can engage in the retaining edge 41a and the sleeve 8 thus remains in the pen holder 6, thereby implementing the deep-hole marking position or deep-hole marking configuration, and a position in which the hooks 50 can rest against / slide off the respective inclined surfaces 41b and the hooks 50 thus do not engage in the sleeve 8, thereby implementing the writing position or writing configuration.

[0095] Fig. 6, Fig. 7 and Fig. Figure 8 shows the system 2 according to the disclosure in a third embodiment. The following discussion focuses solely on the differences between the third embodiment and the second or first embodiments, and omits a re-description of identical elements.

[0096] The first detent geometry 34 and the first receiving geometry 38 of the third embodiment essentially correspond to the second embodiment. However, the second detent geometry 40 and the second receiving geometry 42 differ from the second embodiment.

[0097] In the third embodiment, a rocker arm 52 with hook 50 is provided instead of the spring 48 with hook 50. The rocker arm 52 extends longitudinally L from the insertion opening 30. In the third embodiment shown here, the rocker arm is located inside a recess 54 of the receiving space 26 and engages switchably in a conical groove 56 of the sleeve 8. Specifically, the rocker arm 52 can be moved into a first position in which the hook 50 engages in the conical groove 56, thus coupling the sleeve 8 to the pen holder 6. Furthermore, the rocker arm 52 can be moved into a second position in which the hook 50 does not engage in the conical groove 56, and thus the sleeve 8 is not coupled to the pen holder 6, but is coupled to the writing instrument via the first detent geometry 34 and the first receiving geometry 38.

[0098] In the third embodiment, the switching unit 46 is a rotary knob 46c which, for example via a cam (not shown), switches the rocker arm 52 between the first position and the second position. Alternatively to the rotary knob 46c, a sliding element 46d can also be used (see, for example, [reference]). Fig. 10) be implemented.

[0099] Fig. Figure 9 shows an alternative locking mechanism that can be used for both the first detent geometry 34 with the first receiving geometry 38 and the second detent geometry 40 with the second receiving geometry 42. Essentially, the alternative locking mechanism is a bayonet fitting. In other words, the first detent geometry 34 can be separated from the first receiving geometry 38, and the second detent geometry 40 from the second receiving geometry 42, respectively, by means of a rotary-push movement.

[0100] Fig. 11 and Fig. Figure 12 shows a first modification of the second detent geometry 40 or second receiving geometry 42 of the third embodiment. In this modification, the rocker arm 52 can extend outside the receiving space 26 and be actuated via a rocker switch 58.

[0101] Fig. Figure 13 shows a second modification of the third embodiment. In contrast to the third embodiment, the rotary wheel 46c is replaced here by a rotary section 46e, which extends further in the longitudinal direction L and, due to a larger gripping surface, enables safe handling with wet or dirty fingers.

[0102] Fig.Figure 14 shows a modification of the second locking geometry 40 or second receiving geometry 42 of the first embodiment. In the modification, no wedge-shaped recesses are formed, but the trapezoidal elements 44 are designed as spring elements which are tensioned / tensioned against the conical base body wall 28 of the base body 24.

[0103] Naturally, the different first detent geometries and the different second detent geometries 40 of the various embodiments described above can be interchanged, insofar as this is technically feasible. It is also possible to interchange or combine suitable first detent geometries and suitable second detent geometries, or their technical implementations, of the different embodiments.
