Description

technical field

The present disclosure relates to a writing instrument, and more particularly to a multifunctional writing instrument.

Background to the Revelation

Writing instruments are used in almost all areas of everyday life. Of course, writing implements are also used in the construction and industrial trades. An example of such writing implements is a carpenter's pencil, which is used for marking on materials such as wood, concrete or masonry. This is characterized by a broad, non-conical tip. Other examples include a multigraph pencil and a carpenter's pencil. Such pens have the disadvantage that they have a relatively large diameter and are therefore unsuitable for marking through objects or through holes or bores in the objects.

Based on this circumstance, deep hole markers for markings in places that are difficult to access have recently established themselves on the market. Such deep-hole markers have a long, thin lead holder, which holds and guides the lead with a small diameter. A disadvantage of such deep hole markers is that they have to be gripped by a user at a distance from a writing tip and are therefore unsuitable for normal writing.

State of the art

To solve this problem, the DE 20 2021 103 608 U1 a writing implement in the form of a deep hole marker with a tip-side housing section which is detachably screwed to a further housing section. The writing utensil can be used as a normal writing utensil when the tip-side body portion is screwed on. When the tip-side body portion is unscrewed/disassembled, the writing instrument can be used as a deep hole marker.

A disadvantage of such a writing implement is that conversion is relatively complicated and, in particular, that conversion requires both hands. However, such a two-handed conversion is often disruptive or even impossible, especially in assembly situations on construction sites or in the trade. Another disadvantage is that when the tip-side housing section is dismantled, it has to be stowed away separately from the writing implement and the risk of losing the tip-side housing section is increased.

Summary of Revelation

It is therefore the object of the present disclosure to provide a writing instrument which eliminates or at least reduces the disadvantages of the prior art. Specifically, the object of the present disclosure is to provide a writing implement that can be transferred from a conventional writing implement to a deep hole marker and back from a deep hole marker to a conventional writing implement in a simple manner and with a reduced risk of losing the tip-side housing section.

This object is achieved by a writing implement according to independent claim 1. Further developments and embodiments are claimed in the subclaims and/or described below.

In concrete terms, the object is achieved by a writing instrument with a lead holder which is provided and designed to receive and fix a writing lead, preferably in a central fiber/central axis position of the writing instrument, the lead holder being connected to a writing tip formed on an end section of the lead holder or is formed, and a housing which surrounds the mine receptacle at least partially. Furthermore, the writing implement includes a sleeve which can be moved, in particular moved or shifted, axially between at least one writing position, in which the sleeve radially encloses/surrounds the lead receptacle and the writing tip is exposed, and a deep hole marking position, in which the writing tip is exposed and the lead receptacle is at least partially exposed , with the sleeve and housing in overlap in the down hole marking position.

In other words, the object is achieved by the writing instrument, which contains a thin, essentially tubular lead holder at a central axis position of the writing instrument. The tubular lead holder is provided and designed to fix a writing lead (reversible/detachable). The writing lead can be a ballpoint pen lead, a gel roller lead, a pencil lead, a colored pencil lead, a charcoal lead, a wax lead, a felt pen lead or any other suitable writing lead. The writing tip is formed on the end section of the lead receptacle. The writing tip can be connected to the lead holder. Alternatively, the writing tip can be formed integrally or in one piece with the lead receptacle. The writing instrument includes a housing that holds the refills acquisition in a radial direction at least partially surrounds. The writing implement further includes a sleeve. The sleeve can be moved/moved axially in relation to the lead holder. Specifically, the sleeve can be reversibly shifted or moved between at least one writing position, in which the lead receptacle is surrounded radially by the sleeve, into a deep hole marking position, in which the lead receptacle is at least partially exposed. In the deep hole marking position, the sleeve and the housing overlap at least more than 30%, preferably more than 80%. Here, the housing can cover the sleeve radially. Alternatively, the sleeve can cover the housing radially.

The core of the invention is a writing instrument that can be used both as a conventional pen and as a deep hole marker, the writing instrument containing a sleeve that is inseparably connected to the housing.

By designing the writing implement in this way, the writing implement can be moved from a writing position to a deep hole marking position with one hand.

Furthermore, the sleeve can be prevented from being separated from the writing implement and hence a risk of losing the sleeve increases significantly.

In a first aspect, the housing can contain a holding section which is connected in a rotationally fixed manner to the lead receptacle and an actuating section which can be rotated about the lead receptacle, with the sleeve being able to be moved/inserted into the actuating section of the housing.

In other words, the housing may include the holding portion, which may be formed at an end of the writing instrument remote from the writing tip. The holding section can include an activation element for a feed mechanism for the writing lead in the lead receptacle. The activation element can be a push button or a rotary knob, for example. Furthermore, the housing may include an operating portion. The actuation section can be mounted so that it can rotate about the lead receptacle. The actuation section can be mounted in or on the holding section. The sleeve can move or be able to move into the actuating section. In other words, an inner diameter of the actuation section can essentially correspond to an outer diameter of the sleeve, and the sleeve can be guided in the actuation section. The actuation section can function as a rotary effector of the retraction process.

By designing the writing implement in this way, the writing implement can have compact dimensions both in the writing position and in the deep hole marking position. Furthermore, the one-handed operation of the writing instrument is further simplified by a rotary functionality of the actuating section.

In a further aspect, an axial extent of the sleeve can essentially/approximately correspond to an axial extent of the actuating section. Alternatively, the sleeve can have an axial extent that is shorter than the axial extent of the actuating section. In this way it can be ensured that the sleeve can be introduced into the actuating section.

In a further aspect, the sleeve can have a thread in which an engagement section connected to the housing engages.

A rotational movement can be converted into an axial movement by such a pairing of thread and engagement section. According to the disclosure, however, other means for converting a rotational movement into an axial movement are also conceivable, such as a pin engaging in a slideway! Head Start.

In a further aspect, the thread can be an internal thread and the engagement section can be connected or formed in a rotationally fixed manner with the holding section.

In other words, the sleeve can have/contain the thread, which is preferably designed as an internal thread and which extends over a cylindrical section of the sleeve. The engagement section, which contains engagement fingers, for example, can engage in the thread. The engagement section can preferably be connected or formed in a rotationally fixed manner to the housing and in particular to the holding section of the housing.

Such a design of the sleeve and the housing allows the sleeve to be moved in and out of the actuating portion by rotating the actuating portion relative to the holding portion or by rotating the sleeve relative to the holding portion. In other words, the thread translates the rotational movement of the actuation section into the axial retraction or extension movement of the sleeve.

In a further aspect, a latching element can be formed between the holding section and the operating section, the operating section to be reversibly fixed in locking positions against the holding section.

In other words, a latching element can be formed, preferably in a contact surface/abutment surface between the actuating section and the holding section, with the latching element releasably blocking rotation of the actuating section against the holding section.

By designing a locking element in this way, an unintentional movement/displacement of the sleeve and thus an unintentional change between the positions can be prevented.

In a further aspect, the latching element can be a spring element and a latching pin or a latching ball, which are mounted in the holding section and can engage in a recess of the actuating section.

In other words, the spring and the detent pin/the detent ball can be formed in a preferably blind hole-like opening in a surface of the holding section facing the actuating section. The spring can press the locking pin against the actuation section. The locking pin can engage in the recesses in the actuating section at predefined locking positions.

In order to turn the actuation section out of a latching position, the latching pin must be pressed out of the recess. For this purpose, a spring force of the spring must be overcome when twisting. Furthermore, with such a configuration, a latching sound and a latching feeling can be generated when the latching pin is pressed into the recess in the operating section by the spring. The click noise and the click feel gives the operator/user a valuable impression of the writing instrument.

In a further aspect, the latching positions can be distributed uniformly over the circumference of the writing instrument, preferably at an angle of rotation of approximately 120° to one another.

In other words, more than one recess can be formed in the actuation section, so that several locking positions are passed through with each rotation of the actuation section. The locking positions can be arranged evenly distributed. In particular, three recesses can be formed over the circumference of the actuating section.

With such a design, the insertion depth of the sleeve can be finely adjusted. In particular, intermediate stages between the writing position and the deep hole marking position can also be implemented in this way.

In a further aspect, the sleeve can be brought into a transport position in which the writing tip is surrounded radially by the sleeve.

In other words, the sleeve can be extended further axially than the writing position.

The writing tip can be protected from damage and dirt by the sleeve. Furthermore, unintentional marking of the writing implement can be prevented.

In another aspect, the housing may have a substantially triangular cross-sectional area.

A triangular cross-sectional area is ergonomic, easy to grip, secured against slipping and offers plenty of space for imprints.

In another aspect, the sleeve may have a substantially round cross-sectional area.

In other words, the sleeve can be configured essentially (in sections) as a circular cylinder and in the shape of a truncated cone. In concrete terms, a foremost section oriented in the direction of the writing tip can be designed in the shape of a truncated cone and merge into the circular-cylindrical section in the direction of the holding section.

In a further aspect, the housing can be made of plastic.

In a further aspect, the sleeve can be made of plastic. By designing the housing and/or the sleeve from plastic, the writing implement is inexpensive to manufacture and robust. Furthermore, the writing instrument is comfortable to hold even in cold surroundings and is resistant to environmental influences.

In a further aspect, the lead holder can be made of metal. Since the lead holder has a comparatively thin diameter with a high longitudinal extent, the lead holder is particularly susceptible to buckling. If the lead holder is made of metal, the lead holder can be prevented from buckling.

In a further aspect, the lead receptacle can be a receptacle in the manner of a mechanical pencil.

In a further aspect, the writing instrument can have a fixing clip on one of the writing tips include remote end portion. The fixing clip can preferably be formed on the holding section of the housing. The fixing clip allows the writing instrument to be attached to a belt, for example.

In a further aspect, the actuating section can include a first corrugation, preferably in the form of projections, on a circumference.

In other words, the actuation section can contain projections or elevations, which make it easier to handle the writing instrument, particularly in adverse environments and situations.

In a further aspect, the sleeve can include a second corrugation, preferably in the form of recesses, on a circumference.

In a further aspect, at least 20 mm of the lead receptacle can be exposed in the deep hole marking position.

In other words, the sleeve can be moved/shifted over at least 20 mm. The sleeve can preferably be moved/displaced over more than 30 mm, particularly preferably over approx. 40 mm. In this way, deep holes can also be marked in the deep hole marking position.

In a further aspect, the housing can contain a scale which depicts a travel depth of the sleeve.

Description of the exemplary embodiments

Embodiments of the present disclosure will be described below based on the accompanying figures.

1 shows a writing implement 1 according to the disclosure in a writing position. In the writing position, the writing instrument 1 has a geometry reminiscent of a conventional ballpoint pen. The writing implement 1 includes a housing 3 having a holding portion 5 and an operating portion 7. The operating portion 7 is disposed in relation to the holding portion 5 around a lead receptacle 9 (see, for example 2 ) pivoted. A writing tip 11 is formed on a first end section of the lead receptacle 9 . The writing tip 11 can be formed integrally and/or in one piece with the lead holder 9 . Alternatively, the writing tip 11 can be pressed, glued or fixed in some other way in the lead receptacle. The lead receptacle 9 is provided and designed to fix a writing lead (not shown) and to make it available at the writing tip 11 . In the embodiment shown here, the lead holder is a lead holder based on a mechanical pencil principle. Other embodiments are of course also conceivable, for example as a ballpoint pen or fiber marker.

Furthermore, the writing implement 1 includes a sleeve 13 which can be moved axially along the lead receptacle 9 into the actuating section 7 . In other words, the sleeve 13 surrounds the lead holder 9 at least in sections depending on a positioning of the sleeve 13 in a radial direction. A clip 15 is formed on the holding section 5 in order to fix the writing instrument 1 to a belt, for example. Furthermore, an activation element 17 is formed on an end section of the writing instrument 1 facing away from the writing tip 11 . The activation element 17 activates a feed mechanism (see 27 in 4 ), which provides the writing mine at the writing tip 11 and/or tracks it. Optionally, the activation element 17 can contain an eraser, a sharpener or the like in a preferably screwed end cap 19 (see FIG 4 ).

Projections 21 are formed on the actuating section 7 in order to prevent the writing instrument from slipping off. Furthermore, 13 recesses 23 are formed on the sleeve to prevent slipping.

2 shows the writing instrument 1 according to the disclosure in a deep hole marking position/ deep hole marking position. In the deep hole marking position, the sleeve 13 is essentially retracted into the actuating section 7 . In other words, the rod-shaped lead receptacle 9 is at least partially exposed and allows the writing tip 11 and the lead receptacle 9 to be inserted into openings and bores. Alternatively, it is also conceivable to move the sleeve 9 over the actuating section 5 . In the deep hole marking position, the writing instrument 1 acts as a deep hole marker.

3 shows the writing implement 1 according to the disclosure in a transport position. In the transport position! In the transport position, the sleeve 9 is extended further axially than in the 1 illustrated writing position. In the transport position, the sleeve 9 completely surrounds both the lead receptacle 9 and the writing tip 11 in the radial direction. The formation of such a transport position prevents the writing cartridge from making unwanted markings, for example when the writing implement 1 is being transported in a trouser pocket.

4 shows the writing instrument 1 according to the disclosure in a longitudinal section. In particular shows 4 the longitudinal section of the in 3 illustrated writing instrument 1 in the transport position. The end cap 19 formed on the end section reversibly closes a lead feed opening 25 . The lead supply opening 25 is connected to the lead receptacle 9, which extends on a central fiber of the writing instrument 1. The lead holder 9 is also connected/coupled to a feed mechanism 27 which can be activated via the activation element 17 designed as a push button and which feeds the lead in the axial direction in the lead holder 9 towards the writing tip 11 .

The holding section 5 is non-rotatably connected to an engagement section 29 . The engaging portion 29 has a substantially sleeve-like shape and extends, starting from the holding portion 5 into the actuating portion 7. The actuating portion 7 can be rotated relative to the holding portion 5 and the engaging portion 29 about the engaging portion 29. The actuating section 7 is mounted at a bearing point 31 between the holding section 5 and the engagement section 29 . The engagement section 29 also includes engagement fingers 33 which extend radially outwards at an end section of the engagement section 29 which faces away from the bearing point 31 in the longitudinal direction. The engagement fingers 33 engage in an internal thread 35 formed in the sleeve 13 . An outer diameter of the sleeve 13 essentially corresponds to an inner diameter of the actuating section 7, so that the actuating section 7 guides the sleeve 13 during an axial displacement.

A latching element 37 is formed between the holding section 5 and the actuating section 7 . The latching member 37 is a ball and a spring formed in a blind hole in the holding portion. The spring pushes the ball towards the operating section 7 so that the ball snaps into recesses formed in the operating section 7 at predefined positions.

Furthermore, a guide groove 39 is formed on an inner surface of the actuating section 7, in which a guide element 41 of the sleeve 13 engages. The guide element 41 in the guide groove 39 prevents a rotational movement of the sleeve 13 relative to the actuating section 7.

If the actuating section 7 is now rotated relative to the holding section 5, the engagement fingers 33, which engage in the internal thread 35, convert the rotational movement into an axial movement of the sleeve 13. The guide groove 39 and the guide element 41 prevent the sleeve 13 from rotating as well prevented. A displacement speed of the sleeve 13 relative to the actuating section 7 can be predetermined via a pitch of the internal thread 35 .

5 shows the writing instrument 1 in a rear view. Both the holding section 5 and the actuating section 7 essentially have a triangular cross-sectional shape with rounded corners. The re 4 The recesses described in the actuating section 7, in which the ball of the locking element 37 engages, are preferably formed in corner sections of the actuating section 7.
