Description

The invention relates to a device for sharpening pencils, in particular for sharpening pencils of different diameters, comprising two sharpener units, each comprising a housing part and at least one sharpening device which is arranged or formed at least in sections in the housing part and comprises at least one sharpening element which is accessible via an access opening .

Such devices, sometimes also referred to as “double or multiple sharpeners”, are known per se. The particular practicality of these devices is that they have two sharpening units which (each) comprise different sharpening devices, by means of which different pencils, i. H. in particular, pins having different outer diameters or different (geometric) outer configurations can be sharpened; different pencils can be sharpened with one and the same device.

In the case of corresponding sharpening units, there is the problem of an undesired discharge of material removed in a respective housing part and produced during a sharpening process through the respective access openings on the sharpener device.

U.S. 5,987,759 A discloses a pencil sharpener having a closable sharpener opening.

DE 15 11 450 A1 discloses a pencil sharpener.

U.S. 2009/067912 A1 and DE 15 11 450 A1 disclose pencil sharpeners that have multiple sharpening units and are suitable for use with pencils of various diameters.

The invention is based on the object of specifying an improved device for sharpening pins, in particular for sharpening pins of different diameters.

The object is achieved by a device according to claim 1 and by a device according to claim 2. The dependent claims relate to special developments of the respective device(s).

The device described herein is generally for sharpening pens. Depending on the configuration of the device, pins with different (geometric) external configurations, ie in particular different diameters or different cross-sectional geometry, can be sharpened with this device. The device can be referred to as or considered "double or multiple sharpener" in the appropriate configuration. In principle, any type of pencil that can be sharpened, ie in particular paint, cosmetic, writing or drawing pencils, can be sharpened with the device.

The device includes two (separate) sharpening units. Each sharpener unit comprises a housing part designed in one or more parts, as will be seen below, and at least one sharpener device arranged or formed at least in sections in the housing part. Each sharpening device comprises at least one sharpening element, which is accessible via an access opening, which is in particular conical or funnel-shaped, and is in particular blade- or cutting-edge-shaped. The respective sharpening devices typically differ from one another in that different pencils can be sharpened with the respective sharpening devices. Specifically, the respective sharpening devices differ e.g. B. in the geometric design, d. H. e.g. B. the cone or funnel-like course, respective access openings or in various parameters influencing the tip properties, d. H. e.g. B. the arrangement, the cut, etc., respective pointed elements.

Respective housing parts have a base body. The base body delimits a receiving space that defines a specific spatial volume. The spatial volume is partially occupied by corresponding sharpening devices arranged or formed in the receiving space. The volume of space that is not used by corresponding sharpening devices and is therefore free is set up as a reservoir for receiving material removed when pencils are sharpened. The receiving space is therefore used both for receiving at least one sharpening device, at least in sections, and for receiving material removed during a sharpening process.

A respective basic body can have any basic geometric shape. For example, the base body a cylindrical or cylinder-like, a prismatic or prism-like basic shape or a polygonal, z. B. have a triangular, pentagonal, etc., basic shape. Regardless of its basic shape, the base body can be designed to be open on one side. In order to form a receiving space delimited by the base body, a cover element, in particular a plate-like one, can be provided, optionally as part of a sharpening device of a respective sharpener unit, which can be releasably connected or is connected to the base body in the area of the open side of the base body.

The device is equipped with one or more closing elements in order to take account of the problem mentioned at the outset of undesired escape of removal material located in a respective housing part and produced during a sharpening process through respective access openings on the sharpener device. By providing corresponding closing elements, the respective access openings on the sharpener device side can be closed as required, so that an undesired escape of material removed in a respective housing part and produced during a sharpening process is not possible.

A first embodiment of the device is characterized by a (single) closing element. The two sharpener units assignable or associated closing element is between a first closed position in which it closes the access opening(s) of a first sharpener and a first open position in which it does not close the access opening(s) of the first sharpener, and between a second closed position in which it closes the access opening(s) a second sharpener, and a second open position in which it does not occlude the access opening(s) of the second sharpener. The first embodiment of the device thus comprises a closing element which is used to open and close all access openings of a first sharpening device belonging to a first sharpener unit and to open and close all access openings of a second sharpening device belonging to a second sharpening unit, and therefore to simultaneously open and close all access openings of all sharpening devices on the sharpener unit side is set up. The closing element is movable, in particular pivotally movable, articulated relative to the access openings on the sharpener device side on a part of the device, ie for example on a housing part or on a connecting element connecting the housing parts on the sharpener unit side to one another. A special position of the closing element given a special arrangement of the sharpener units relative to one another, in which the sharpener units are typically connected to one another at the front, makes it possible to close both the first access opening and the second access opening via the closing element; the closing element is here therefore both in the first and in the second closed position. In this arrangement of the sharpener units, respective access openings on the sharpener unit side or their entry areas are typically aligned facing one another, possibly with a specific lateral offset.

A second embodiment of the device is characterized by two (separate) closing elements. A first closure member associated with a first sharpening unit is movable between a closed position in which it closes the access opening(s) of a first sharpening device associated with the first sharpening unit and an open position in which it does not close the access opening(s) of the first sharpening device. A second closure member associated with a second sharpening unit is movable between a closed position in which it closes the access opening(s) of a second sharpening device associated with the second sharpening unit and an open position in which it does not close the access opening(s) of the second sharpening device. The second embodiment of the device thus comprises two separate closing elements, with a first closing element being set up to open and close all access openings of a first sharpening device belonging to a first sharpening unit and a second closing element being set up to open and closing all access openings of a second sharpening device belonging to a second sharpening unit. The first closing element is articulated on the first sharpener unit in a movable, in particular pivotally movable, manner relative to its sharpener-side access opening. The second closing element is articulated on the second sharpener unit in a movable, in particular pivotally movable, manner relative to its sharpener-side access opening.

For both embodiments, the respective closing element covers or closes the respective access opening(s) in the respective closed positions, so that it is not possible to insert a pin into the respective access opening(s). Equally, it is not possible for removal material that may be contained in the respective housing part to exit via the respective sharpener units or via the respective access opening(s) on the sharpener unit. Conversely, the respective closing element does not cover the respective access opening(s) in the respective open positions, so that it is possible to insert a pin into the respective access opening(s).

It also applies to both embodiments that in the mentioned special arrangement of the sharpener units relative to one another, in which the sharpener units are connected to one another, typically at the front, the closing element(s) are typically arranged in a fixed position between the respective housing parts on the sharpener unit side ("sandwich arrangement") . In this arrangement of the sharpener units, respective access openings on the sharpener unit side or their entry areas are typically aligned facing one another, possibly with a specific lateral offset.

A respective closing element typically has a flap- or plate-like base body which can be moved, in particular pivoted, relative to a respective access opening, e.g. B. is arranged on a respective housing part.

In order to enable a respective access opening to be sealed off in a respective closed position, at least one sealing element can be arranged or formed on a respective closing element. A corresponding sealing element is expediently adapted to the inner contour of an access opening that can be assigned or assigned to it, so that in a respective closed position it can protrude at least in sections into the access opening that can be assigned or assigned to it. For the example of a cone-shaped or funnel-shaped access opening with a ring (disk)-shaped entrance area, a sealing element z. B. be formed as a ring (disc)-shaped extending projection which protrudes sealingly in the respective closed position in the entrance area of the access opening. In the respective closed position, the outer contour or the outer circumference of the projection bears sealingly against the inner contour or the inner circumference of the entry area of the access opening. Of course, this principle applies analogously to access openings that are designed differently in terms of geometry and construction. In order to increase the sealing effect, a sealing element can be formed at least in sections from an elastomer material or can be provided with such an elastomer material.

The two sharpener units of the device can be or can be connected to one another via at least one connecting element. The connection between the two sharpener units that can be produced or produced via a corresponding connecting element can in principle be detachable (without damage or destruction) or non-detachable (without damage or destruction).

First, various alternatives should be considered, according to which the two sharpener units are detachably connected to one another. There are typically at least two connecting elements that correspond to one another, with at least one first connecting element being assigned to a first sharpener unit and at least one second connecting element being assigned to a second sharpener unit. The connecting elements that correspond to one another are designed to work together to form a detachable connection between the two sharpener units.

In this case, a first connecting element can be designed as a force-fitting element or as a form-fitting element. A second connecting element can be designed as a counter-force-locking element corresponding to the force-locking element or as a counter-positive-locking element corresponding to the form-locking element. The force-locking and counter-force-locking elements or form-locking and counter-form-locking elements that correspond to one another are set up to interact in a force-locking or form-locking manner, forming a detachable connection of the two sharpener units.

A detachable connection of the two sharpener units can (alternatively or additionally) also be realized by a magnetic connection. In this case, a first connecting element can be designed as a magnetic element or at least include one. A second connecting element can be embodied as a counter-magnetic element that (magnetically) corresponds to the magnetic element, or can at least comprise such a counter-magnetic element. The mutually corresponding magnet and counter-magnet elements are set up to magnetically interact or interact with the formation of a detachable connection of the two sharpener units. Corresponding magnetic or counter-magnetic elements consist at least in sections of (permanent) magnetic material, e.g. B. an iron-cobalt-nickel alloy, or magnetizable material such. B. ferritic steel. This also applies to all magnet and counter-magnet elements mentioned below.

Corresponding force-fitting or form-fitting elements or counter-force-fitting or counter-form-fitting elements can be formed integrally with a section of the respective sharpener unit or a section of the respective housing parts on the sharpener unit. Corresponding magnetic elements or counter-magnetic elements can be integrated at least in sections, in particular completely, into a section of the respective sharpener unit, e.g. B. by overmoulding with a spray material forming the respective section of the sharpener unit, d. H. typically a thermoplastic plastics material.

For the geometric-constructive arrangement of the respective traction elements, Positive-locking elements and/or magnetic elements or for the corresponding counter-elements in connection with corresponding connecting elements, the following applies in particular:
A corresponding force-fitting, form-fitting or magnetic element can be arranged or formed on a section of the first sharpener unit that delimits the receiving space on the housing part side. A corresponding counter-force closure, counter-form closure or counter-magnet element can be arranged or formed on a section of the second sharpener unit that delimits a receiving space on the housing part side.

In particular, the force-fitting, form-fitting or magnetic element can be attached to an exposed (upper) section of the housing part of the first sharpener unit when the two sharpener units are not connected to one another, in particular to an end face or side of a (substantially) cylindrical or prismatic housing part forming section, or on a section of a cover element that can be connected or connected to a base body of the housing part of the first sharpener unit, in particular a plate-like one, that is exposed when the two sharpener units are not connected.

It is also conceivable that a force-fitting, form-fitting or magnetic element is arranged or formed on a first closing element associated with the first sharpener unit (cf. the above-mentioned second embodiment of the device). In particular, the force-fitting, form-fitting or magnetic element can be arranged or formed on a section of the first closing element that is exposed when the first closing element is in the closed position.

The following applies in particular to the geometric-constructive arrangement of the respective counterforce locking elements, counter-form locking elements or counter-magnetic elements in connection with the corresponding connecting elements:
A non-positive locking, counter-positive locking or counter-magnetic element can be arranged or formed on the housing part of the second sharpener unit or on a cover element that can be connected or connected to a base body of the housing part of the second sharpener unit, in particular a plate-like one, in particular as part of the sharpening device of the second sharpener unit. In particular, the counter-force closure, counter-form closure or counter-magnetic element on a non-connected state of the The (upper) section of the housing part of the second sharpener unit that is exposed on both sharpener units, in particular on a section that forms an end face of a (substantially) cylindrical, in particular prismatic, housing part, or on a section of one with a base body that is exposed when the two sharpener units are not connected The housing part of the second sharpener unit can be connected or connected, in particular a plate-like cover element.

In particular, the counterforce closure, counterform closure or countermagnet element can be arranged or formed on a section of the second closing element that is exposed when the second closing element is in the closed position.

The following applies in particular to the geometric-constructive design of the respective force-fitting and counter-force-fitting elements or respective form-fitting and counter-form-fitting elements in connection with the corresponding connecting elements:
A force-fitting element or a form-fitting element can be designed as a projection, in particular running like a strip or an edge, on the housing part of the first sharpener unit or a cover element or a closing element that can be connected or connected to a base body of the housing part of the first sharpener unit, in particular as a plate. The projection can be formed by a lateral boundary edge of an elevation of the housing part of the respective sharpener unit or a cover element or a closing element that can be or is connected to a base body of the housing part of the respective sharpener unit, in particular a plate-like one. The respective specific geometric-constructive design of the projection determines whether the connection that can be formed with it is force-fitting or form-fitting.

A counter-force-locking element or a counter-form-locking element can be designed as a receptacle, recess or indentation, in particular running like a groove or an edge, on the housing part of the second sharpener unit or a cover element or a closing element that can be connected or connected to a base body of the housing part of the second sharpener unit, in particular a plate-like one be. The receptacle, recess or indentation can be formed by a lateral boundary edge of an indentation in the housing part of the respective sharpener unit or a cover element or a closing element that can be or is connected to a base body of the housing part of the respective sharpener unit, in particular a plate-like one. The respective specific geometric-constructive design of the receptacle, recess or indentation determines whether the connection that can be formed with it is non-positive or positive.

Of course, an inverted geometric-constructive configuration of the respective force-locking and counter-force-locking elements or respective positive-locking and counter-positive-locking elements is possible. If one of a plurality of respective force-fitting and counter-force-fitting elements or respective form-fitting and counter-form-fitting elements is present, the force-fitting and counter-force-fitting elements or the form-fitting and counter-form-fitting elements do not necessarily have to be designed the same in terms of geometry and construction.

Since it is, as mentioned above, in a by interaction of respective connecting elements, i. H. in particular the respective force-locking and counter-force-locking elements or respective form-locking and counter-form-locking elements, the force-locking or positive-locking connection produced by the respective sharpener units can be a clamp, press or plug-in connection, the respective friction-locking and counter-force-locking elements or respective form-locking and counter-form-locking elements can also be used as Clamping and counter-clamping elements, pressing and counter-pressing elements or plug-in and counter-plug elements are designated or considered.

Various alternatives are to be considered below, according to which the two sharpener units are permanently connected to one another. There is typically at least one connecting element which non-detachably connects the two sharpener units to one another. Accordingly, the connecting element is associated with both a first sharpening unit and a second sharpening unit.

(Only) a (single) connecting element can be provided, the connecting element being connected both to the first sharpener unit and to the second sharpener unit. Alternatively, at least two (separate) connecting elements can be provided, with at least a first connecting element being connected to a first sharpener unit and the closing element and at least a second connecting element being connected to a second sharpener unit and the closing element. The closing element is thus connected between the two sharpener units.

Accordingly, a first connection securing element as a frictional element or be designed as a form-fitting element. A second connection securing element can be designed as a counter-force-locking element corresponding to the force-locking element or as a counter-form-locking element corresponding to the form-locking element. The force-locking and counter-force-locking elements or positive-locking and counter-positive-locking elements that correspond in each case to one another are set up to interact in a form-fitting manner while securing the sharpener units that have been moved into the connecting position.

In particular, the counterforce closure, counterform closure or countermagnet element can be arranged or formed on a section of the second closing element that is exposed when the second closing element is in the closed position.

A closure securing element can be a form-fitting element arranged or formed on the closing element, which in the closed position of the closing element has a form-fitting connection with a corresponding counter-form-fitting element on the housing part of the respective sharpener unit or on a cover element that can be connected or is connected, in particular a plate-like one, to a base body of the housing part of the respective sharpener unit. works together.

The sharpening devices 6, 7 each comprise at least one sharpening element (not denoted in more detail) which is in the form of a blade or cutting edge and can also be referred to as a “sharpener knife”. The respective sharpening device-side sharpening elements are accessible via access openings 8, 9 which extend in the manner of a cone or funnel and protrude into the respective receiving spaces 12, 13. In the exemplary embodiments, the sharpening device 6 associated with the first sharpener unit 2 comprises a (single) sharpening element accessible via a (single) access opening 8 and the sharpening device 7 associated with the second sharpening unit 3 comprises two sharpening elements accessible via a respective access opening 9 . The second sharpening device 7 is therefore intended for sharpening pencils of different outside diameters, which results from the differently dimensioned access openings 9 . The first sharpening device 6 is designed for sharpening pencils with a different, i.e. H. larger, outer diameter determined, which results from the compared to the access openings 9 of the second sharpening device 7 differently dimensioned access opening 8. Of course, other configurations of the respective sharpener devices 6, 7 on the sharpener unit side are conceivable.

In order to counteract the problem of removal material located in a respective housing part 4, 5 undesirably escaping through respective access openings 8, 9 on the sharpener device, the device 1 is equipped with one or more closing elements 14, 14a, 14b. The respective access openings 8, 9 on the sharpener device side can be closed as required by the closing element(s) 14, 14a, 14b; an undesired escape of ablated material is then not possible.

For all exemplary embodiments, it applies accordingly that the respective access opening(s) 8, 9 are covered or closed by the respective closing elements 14, 14a, 14b in the respective closed positions of the closing elements 14, 14a, 14b, so that an exit from in removal material contained in the respective housing part 4, 5 via the respective sharpener units 2, 3 or via the respective access opening(s) 8, 9 on the sharpener unit is not possible. Likewise, in the respective closed positions of the closing elements 14, 14a, 14b, insertion of a pin into the respective access opening(s) 8, 9 is not possible.

Further, partly common functional-constructive details of the sharpener units 2, 3 according to the different exemplary embodiments of the device 1 are explained in detail below in connection with the respective more detailed description of the exemplary embodiments:
In the Figures 1 - 7 different views of a device 1 according to a first embodiment are shown: 1 is a perspective view of the device 1, 2 is a partially broken perspective view of the device 1, 3 is a side view of the device 1, 4 , 5 are each perspective representations of first sharpener unit 2 of the device 1, Figures 6, 7 are perspective representations of the second sharpener unit 3 of the device 1.

The device 1 according to the first exemplary embodiment comprises two (separate) closing elements 14a, 14b (cf. Figures 4 - 7 ). The first closing element 14a assigned to the first sharpener unit 2 is between a closed position (cf. 6 ), in which it closes the access opening 8 of the first sharpening device 6, and an open position (cf. figure 5 ) in which it does not close the access opening 8 of the first sharpening device 6. The first closing element 14a has a flap-like or plate-like base body (not designated in more detail), which is articulated by means of a film hinge 16 (pivotingly) movable relative to the access opening 8 on a plate-like cover element 15 fastened (releasably) to the front of the base body 10. The cover element 15 can form part of the first sharpener device 6, ie the first sharpener device 6 and the cover element 15 can be designed integrally with one another.

The second closing element 14b assigned to the second sharpener unit 7 can be moved between a closed position in which it closes the access openings 9 of the second sharpening device 7 and an open position in which it does not close the access openings 9 of the second sharpening device 7. The second closing element 14b also has a flap-like or plate-like base body (not designated in more detail), which is articulated by means of a film hinge 18 (pivotingly) movable relative to the access openings 9 on a plate-like cover element 17 fastened (releasably) to the front of the base body 11 . The lid member 17 may form part of the second sharpening device 7, i. H. the second sharpener 7 and the lid member 17 may be integral with each other.

Although not shown in the figures, the second closing element 14b could of course also be designed in several parts, i. H. a plurality of closing element parts (not shown) which are each assigned to a (single) access opening 9 and can be moved independently of one another.

Based on Figures 1, 3 It can be seen that the two sharpener units 2, 3 can be or are connected to one another in a detachable manner. The detachable connection of the sharpener units 2, 3 is realized via respective sharpener-side connecting elements 19, 20, with a first connecting element 19 being assigned to the first sharpener unit 2 and a second connecting element 20 corresponding to the first connecting element 19 being assigned to the second sharpener unit.

The detachable connection of the two sharpener units 2, 3 is realized by a non-positive connection, ie a non-positive clamp, press or plug connection. The first connecting element 19 is designed as a force-fitting element 21 . When the frictional element 21 is a strip or edge-like running, from the cover element 15 (vertically) protruding projection (see. In particular 4 , 5 ). The second connecting element 20 is embodied as a counter-force-locking element 22 that corresponds to the force-locking element 21 . The counterforce element 22 is an edge-like recess formed by a lateral delimiting edge of a depression in the cover element 17 . The force-locking and counter-force-locking elements 21, 22, which correspond to one another in each case, are set up to cooperate in a force-locking manner, forming a detachable connection between the two sharpener units 2, 3.

Based on Figures 3 - 7 form-fitting elements 23 and counter-form-fitting elements 24 formed on the force-fitting element 21 or the counter-force-fitting element 22 can also be seen. The form-fitting elements 23 distributed on the outside along the force-fitting element 21 are projections. The counter-positive locking elements 24 distributed on the inside along the counter-positive locking element 22 are receptacles that correspond to the projections, whereby, as will be seen below, an inverted configuration would of course also be possible. The projections act in the Figures 1, 2 shown connection position of the sharpening units 2, 3, in which the sharpening units 2, 3 are moved against each other on the front (surface) side, with the receptacles together in a form-fitting manner. In this way, the sharpener units 2, 3 moved into the connecting position are secured. The positive-locking elements 23 and counter-positive-locking elements 24 therefore serve as connection securing elements, which are set up to secure the connection position.

Based on 4 , 7 further sealing elements 26, 27 formed on the closing element side can be seen. The sealing elements 26, 27 are adapted to the inner contour of the access opening(s) 8, 9 assigned to them, so that in a respective closed position they protrude into the access opening(s) 8, 9 assigned to them. The conical or funnel-like access openings 8, 9 have an annular (disk)-shaped entrance area. The sealing elements 26, 27 are in the Figures 4 - 7 correspondingly designed as annular (disc)-shaped projections, which in the respective closed position project sealingly into the entrance area of the respective access opening(s) 8, 9. It would also be conceivable to design the sealing elements 26, 27 as funnel-like projections which, in the respective closed position, protrude into the entrance area of the respective access opening(s) 8, 9 to form a seal. The outer contour or the outer circumference of the projections are (in both cases) sealing on the inner contour or the inner circumference of the entrance area of the respective access opening(s) 8, 9. In order to increase the sealing effect, the sealing elements 26, 27 can be formed at least in sections from an elastomer material or can be provided with such an elastomer material.

Based on 4 , 7 Furthermore, respective handling elements 28, 29 on the closing element side can be seen. The handling elements 28, 29 are used for better handling Closing elements 14a, 14b, in particular in connection with the transfer by the user of those from a respective closed position into a respective open position. The handling elements 28, 29 are sections that run obliquely with respect to the main plane of the respective closing element 14a, 14b.

In the Figures 8 - 16 different views of a device 1 according to a second embodiment are shown: 8 is a perspective view of the device 1, 9 is a partially broken perspective view of the device 1, 10 is a side view of the device 1, 11 , 12 are perspective representations of the first sharpener unit 2 of the device 1, 13, 14 are perspective views of the second sharpener unit 3 of the device 1; 15, 16 are further perspective representations of the device 1.

A detachable connection of the two sharpener units 2, 3 is here by a non-positive connection, d. H. a non-positive plug-in connection. In contrast to the first exemplary embodiment, respective corresponding connecting elements 19, 20 or respective corresponding force-locking and counter-force-locking elements 21, 22 are not formed or arranged on the cover element side, but rather on the closing element side. Respective form-fitting elements 23 in turn serve as connection securing elements, which are set up to secure the connection position in which the sharpener units 2, 3 are moved towards one another at the front (surface) side.

The force-fitting element 21 forming the first connecting element 19 is a projection that runs like a strip or an edge and protrudes (vertically) from the section of the first closing element 14a that is exposed in the closed position of the first closing element 14a (cf. 11 ). The counterforce element 22 forming the second connecting element 20 is an edge-like recess formed by a lateral boundary edge of a depression in the section of the second closing element 14b that is exposed in the closed position of the second closing element 14b (cf. 13 ). The force-locking and counter-force-locking elements 21, 22, which correspond to one another in each case, are set up to cooperate in a force-locking manner, forming a detachable connection between the two sharpener units 2, 3.

Based on 12, 14 It can be seen that further form-fitting elements 30, 31 and further counter-form-fitting elements 32, 33 are formed on the sections of the respective closing elements 14a, 14b that are exposed in the open position of the respective closing elements 14a, 14b and are therefore not exposed in the closed position of the respective closing elements 14a, 14b . The form-fitting interaction of the respective form-fitting elements 30, 31 on the sharpener unit and counter-form-fitting elements 32, 33 ensures that a closing element 14a, 14b moved into a respective closed position is secured in the respective closed position. The other form-fitting elements on the sharpener unit side 30, 31 and counter form-locking elements 32, 33 therefore serve as locking securing elements which are set up to secure a locking element 14a, 14b moved into a respective locking position in the respective locking position.

The positive-locking elements 30, 31 are each a section of the respective closing element 14a, 14b that protrudes (vertically) from the section of the respective closing element 14a, 14b that is exposed in the open position and thus from the section that is not exposed in the closed position of the respective closing element 14a, 14b projection (cf. 12, 14 ). The projection forming the form-fitting element 30 is formed by a lateral boundary edge of a plateau-like elevation in the section of the first closing element 14a that is not exposed when the first closing element 14a is in the closed position (cf. 12 ). The projection forming the form-fitting element 31 is formed by a strip-like projection protruding (vertically) from the section of the second closing element 14b that is not exposed when the second closing element 14b is in the closed position (cf. 14 ).

The mating form-fitting elements 32, 33 are each an edge-like recess formed by a respective lateral boundary edge of a respective depression in the section of the respective cover element 15, 17 that is exposed in the open position of the respective closing element 14a, 14b (cf. 12, 14 ).

In 15 an arrangement is shown in which the first closing element 14a associated with the first sharpener unit 2 is moved into the open position and the second closing element 14b associated with the second sharpener unit 3 is moved into the closed position. The force-fitting element 21 formed on the first closing element 14a engages in a force-fitting manner in the counterforce-fitting element 22 formed on the second closing element 14b and thus establishes a connection between the two sharpener units 2, 3.

In 16 is one to 15 reversed arrangement is shown, in which the first closing element 14a associated with the first sharpener unit 2 is moved into the closed position and the second closing element 14b associated with the second sharpener unit 3 is moved into the open position. The counter-force-locking element 22 formed on the second closing element 14b positively engages in the force-locking element 21 formed on the first closing element 14a and thus establishes a connection between the two sharpener units 2, 3.

In the 17 - 22 different views of a device 1 according to a third embodiment are shown: 17 is a perspective view of the device 1, 18 is a partially broken perspective view of the device 1, Figures 19 - 22 are further perspective representations of the device 1.

In contrast to the first and second exemplary embodiment, a closing element 14 is provided here only on the side of the first sharpener unit 2 . As follows, the closing element 14 can nevertheless be assigned to both sharpener units 2, 3. The access openings 9 of the second sharpener unit 3 are thus either in the 17, 18 arrangement shown and in the 22 shown arrangement, in which the closing element 14 associated with the first sharpener unit 2 is moved into the open position, with the closing element-side connecting or non-positive locking elements 19, 21 of the first sharpener unit 2 being non-positively connected to the corresponding lid element-side connecting or counter-positive locking elements 20, 22 of the second Sharpener unit 3 cooperate, closed.

Of course, in the opposite configuration, the first sharpener unit 2 could also be designed without a closing element 14 and the second sharpener unit 3 with a closing element 14 .

Based on 20 it can be seen that the positive-locking elements 23, which are designed here as receptacles, and the corresponding counter-positive-locking elements 24, which are designed here as projections, serve both as connection securing elements and as closure securing elements; the form-fitting elements 23 and counter-form-fitting elements 24 are on the one hand to secure the connection position in which the sharpener units 2, 3 are moved towards one another at the front (surface) side, and on the other hand (at least) in relation to the sharpener unit 3 to secure the closing element 14 moved into the closed position in the set up closed position.

As a fundamental difference from the previous exemplary embodiments, the sharpener units 2, 3 according to the three exemplary embodiments described below are no longer detachably but permanently connected to one another.

The connection of the sharpener units 2, 3 is realized in each case by means of one or more connecting elements 34, 34a, 34b designed as hinge elements and arranged on an upper edge area of the or the respective cover element 15, 17. Due to the design of the connecting elements 34, 34a, 34b as hinge elements, the sharpener units 2, 3 can be moved relative to one another, in particular pivoted, and are connected to one another.

In the 23 - 28 different views of a device 1 according to a fourth exemplary embodiment are shown: 23 is a perspective view of the device 1, 24 is a partially broken perspective view of the device 1, 25 - 28 are further perspective representations of the device 1.

As can be seen, the device 1 according to the fourth exemplary embodiment comprises (only) a (single) closing element 14 (cf. 25, 26 ). The closing element 14 assigned to the two sharpener units 2, 3 is between a first closed position (cf. 28 ), in which it closes the access opening 8 of the first sharpening device 6, and a first open position, in which it does not close the access opening 8 of the first sharpening device 6, and between a second closed position (cf. 27 ), in which there are access openings 9 of second sharpening device 7 closes, and a second open position in which it does not close the access openings 9 of the second sharpening device 7, movable. The closing element 14 has a flap-like or plate-like base body (not described in more detail below), which by means of connecting elements 34a, 34b in the form of hinge elements (pivoting) can be moved relative to the sharpener units 2, 3 or the access openings 8, 9 on the sharpener unit, e.g. B. is articulated on the respective end faces of the respective base bodies 10, 11 attached to the housing part-side cover elements 15, 17.

Based on 25, 26 It can be seen that the sharpener units 2, 3 are connected to one another via the two connecting elements 34a, 34b and the interposed closing element 14. A first connecting element 34a connects the first sharpener unit 2 to the closing element 14, a second connecting element 34b connects the closing element 14 to the second sharpener unit 3.

As can be seen, form-locking elements 30, 31 are formed on the closing element 14 and corresponding counter-form-locking elements 32, 33 are formed on the respective cover elements 15, 17 on the sharpener unit. The form-fitting interaction of the respective form-locking elements 30, 31 on the closing element side and the respective counter-form-locking elements 32, 33 on the cover element side ensures that the closing element 14 moved into a respective closed position is secured in the respective closed position, analogously to the second exemplary embodiment. The respective form-fitting elements 30, 31 and counter-form-fitting elements 32, 33 therefore also serve as locking securing elements here, which are set up to secure the closing element 14 moved into a respective closed position in the respective closed position.

The respective positive-locking elements 30, 31 and the counter-positive-locking elements 32, 33 corresponding thereto also serve here as connection securing elements; namely, the form-fitting elements 30, 31 and counter-form-fitting elements 32, 33 are also set up to secure the connection position, in which the sharpener units 2, 3 are moved towards one another at the front (surface) side.

With regard to the form-fitting interaction and the specific geometrical-constructive design of the form-fitting elements 30, 31 and the counter-form-fitting elements 32, 33, the corresponding statements in connection with the second exemplary embodiment apply analogously.

In the Figures 29 - 32 different views of a device 1 according to a fifth exemplary embodiment are shown: 29 is a perspective view of the device 1, 30 is a partially broken perspective view of the device 1, 31, 32 are further perspective representations of the device 1.

The fifth embodiment differs from the previous fourth Embodiment in particular in the basic shape of the housing parts 4, 5 of the respective sharpener units 2, 3, which is triangular here. The triangular basic shape of the housing parts 4, 5 results in the in the 31, 32 "Unfolded" state of the device 1 a three-dimensional spatial extension. Otherwise, all statements in connection with the previous fourth exemplary embodiment apply analogously.

In the 33 - 38 different views of a device 1 according to a sixth embodiment are shown: Figure 33 is a perspective view of the device 1, 34 is a partially broken perspective view of the device 1, 35 - 38 are further perspective representations of the device 1.

In contrast to the fourth and fifth exemplary embodiment, there is only one (single) connecting element 34 for connecting the two sharpener units 2, 3 here. The connecting element 34 is in turn a hinge element. The closing element 14, which is also the only one here, is articulated (pivotingly) movable on the connecting element 34 (cf. Figure 35 ).

With regard to the form-fitting interaction and the specific geometric-constructive design of the respective form-fitting elements 30, 31 on the closing element side or the respective counter-form-fitting elements 32, 33 on the cover element side, the corresponding explanations in connection with the second exemplary embodiment apply analogously - analogously to the fourth exemplary embodiment.

In the 39 - 42 different views of a device 1 according to a seventh embodiment are shown: Figure 39 is a perspective view of the device 1, figure 40 is a partially broken perspective view of the device 1, Figure 41 , 42 are further perspective representations of the device 1.

In contrast to the fourth and sixth exemplary embodiment, the seventh exemplary embodiment comprises two (separate) closing elements 14a, 14b, analogously to the first exemplary embodiment. In this respect, the seventh embodiment can be seen as a combination of the sixth embodiment, from which the direct connection of the sharpener units 2, 3 via a connecting element 34 designed as a hinge element is taken, and the first embodiment, from which the arrangement and design of respective closing elements 14a, 14b on the sharpener unit side is taken , are considered, so that the corresponding statements in connection with the sixth and first exemplary embodiment apply analogously.

For all exemplary embodiments, it is fundamentally the case that as an alternative or in addition to the respective corresponding connection elements in the form of the force-locking elements shown and counterforce-locking elements corresponding thereto, positive-locking elements and corresponding counter-positive-locking elements and/or magnetic elements and thereto Corresponding counter-magnet elements could be present, so that form-fitting and/or magnetic connections would also be conceivable as an alternative or in addition to the respective non-positive connections.

Also conceivable would be combined force and form-fitting elements in the form of threaded elements, i. H. External or internal thread (sections) n. Corresponding combined counter-force and counter-form-locking elements can be counter-thread elements, i. H. Internal or external thread (sections) be. Respective threaded elements and counter-threaded elements can be designed in such a way that a connection of the sharpener units 2, 3 formed by a corresponding thread engagement can be broken by a specific rotation, e.g. B. a 90 ° - or 180 ° rotation, the attached sharpener units 2, 3 relative to each other.

The device 1, ie the individual components (groups) and sub-components (groups) forming it, is at least partially, in particular completely, made of a plastic material, in particular thermoplastic, ie e.g. ABS, PA , PE, PP, PS, formed components. Of course, different components (groups) or sub-components (groups) can be formed from different plastic materials.
