Device for sharpening at least one pencil

Abstract

Device (1) for sharpening at least one pencil.

Description

[0001] The invention relates to a device for sharpening at least one pencil, which comprises a housing part which delimits a receiving space for receiving at least one sharpening unit which has at least one sharpening channel defining a sharpening channel axis, and at least one component which is mounted on the first housing part so as to be pivotable about at least one pivot axis.

[0002] Corresponding devices for sharpening at least one pencil are known from the prior art and comprise at least one housing part which delimits a receiving space for receiving at least one sharpening unit which has at least one sharpening channel defining a sharpening channel axis, as well as at least one component mounted on the first housing part so as to be pivotable about at least one pivot axis.

[0003] Corresponding devices are generally characterized in that a housing part is connected to a further component, such as a further housing part, in such a way that the further component is mounted on the housing part so as to be pivotable about at least one pivot axis.

[0004] In devices known from the prior art, film hinges are sometimes used to connect the housing part to the other component; thus, the housing part is integrally connected to the other component via a film hinge. From a manufacturing perspective, this represents a situation that requires improvement, because the implementation of film hinges requires comparatively complex tooling. Furthermore, such film hinges can sometimes detract from the device's visually appealing, compact appearance. Finally, devices with such film hinges require improvement, because the film hinges are often unstable, can therefore break or tear, and cannot be replaced in the event of damage.

[0005] In other devices known from the prior art, single hinges—i.e., hinges that define a single pivot axis—are sometimes used to connect the housing part to the other component. However, these hinges typically extend beyond the outer periphery of the housing part and the other component and thus require a comparatively large amount of space. Furthermore, the opening angle of the single hinges may be limited, which is particularly true for configurations of corresponding devices with two housing parts.

[0006] The invention is based on the object of providing an improved device for sharpening at least one pencil.

[0007] The object is achieved by a device for sharpening at least one pencil according to claim 1. The dependent claims relate to particular developments of the device for sharpening at least one pencil.

[0008] A first aspect of the invention relates to a device for sharpening or shaping at least one pencil. The device is thus generally designed for sharpening or shaping at least one pencil. In principle, any type of sharpenable pencil, i.e., in particular, a painting, cosmetic, writing, or drawing pencil, can be sharpened or shaped with the device. Specifically, the device can be used, in particular, to sharpen or shape the lead of a pencil, optionally coated with a coating material.

[0009] The device can be configured as a so-called single sharpener or as a so-called double or multiple sharpener. In an exemplary configuration as a single sharpener, the device comprises a first housing part that defines a receiving space for receiving a sharpening unit having a sharpening channel defining a sharpening channel axis. In an exemplary configuration as a double or multiple sharpener, the device can comprise a first housing part that defines a receiving space for receiving a sharpening unit having a plurality of sharpening channels, each defining a sharpening channel axis.In a further exemplary configuration as a double or multiple sharpener, the device can comprise a first housing part, which delimits a receiving space for receiving at least one sharpening unit, which has at least one sharpening channel defining a sharpening channel axis, and a second housing part, which delimits a receiving space for receiving at least one sharpening unit, which has at least one sharpening channel defining a sharpening channel axis. Depending on the specific configuration of the device, it can be used to sharpen or shape one or more pencils with different (geometric) external configurations, i.e. in particular different diameters or different cross-sectional geometries.

[0010] The device therefore comprises at least a first housing part which has or delimits a receiving space for receiving at least one sharpening unit. The spatial volume delimited by the receiving space is partially occupied by a sharpening unit which is received at least partially, optionally completely, in the receiving space. The spatial volume not occupied by the sharpening unit and is therefore free is designed to function as a reservoir for receiving material removed during the sharpening or shaping of pencils. The receiving space or the receiving volume therefore serves both to receive at least one sharpening unit, at least in sections, and also to receive material removed during a sharpening process by means of the at least one sharpening unit. The sharpening unit has at least one sharpening channel, which is in particular funnel-like or funnel-shaped, and which defines a sharpening channel axis.The sharpening channel is accessible via an access opening. The sharpening unit further comprises at least one sharpening element, in particular a blade- or cutting-edge-shaped element, accessible via the access opening into the at least one sharpening channel.

[0011] The first housing part can be constructed in one or more parts. In a multi-part design, the first housing part can comprise a base body open on one side and an attachment body that can be arranged or is arranged on the base body, e.g., by being placed on top. The attachment body can have one or more openings that, when properly arranged on the base body, are aligned with the respective access opening(s) in the respective pointed channel(s).

[0012] The base body can, for example, have a cylindrical or cylinder-like, prismatic or prism-like basic shape, or a polygonal, e.g., triangular, pentagonal, etc. basic shape. The attachment body can, for example, have a plate-like or plate-shaped basic shape. One or more functional areas, explained in more detail below, can be arranged or formed on both the base body and the attachment body.

[0013] All statements relating to the first housing part apply analogously to each further housing part of the device; as will become apparent below, the device may comprise at least two housing parts.

[0014] In addition to the first housing part, the device comprises at least one component; the at least one component may be, for example, another housing part or a cover or closure part associated with the first housing part.

[0015] In all embodiments, and therefore regardless of its specific design, the at least one component is pivotally mounted on the first housing part. The first housing part and the at least one component can thus be moved into different orientations and / or positions relative to one another via corresponding pivoting movements of the at least one component relative to the first housing part. A first orientation and / or position can be one in which no access is possible to the at least one sharpening channel of the at least one sharpening unit accommodated in the receiving space of the first housing part, so that sharpening a pencil with the sharpening unit accommodated in the first housing part is not possible.A second orientation and / or position may be one in which access to the at least one sharpening channel of the at least one sharpening unit accommodated in the receiving space of the first housing part is possible, so that sharpening of a pencil with the sharpening unit accommodated in the first housing part is possible.

[0016] The at least one component can therefore be pivoted into a first pivot position in which it is arranged above an access opening of the at least one sharpening channel of the sharpener unit accommodated in the receiving space of the first housing part, so that insertion of a pin into the at least one sharpening channel of the sharpener unit is not possible, and can be pivoted into a second pivot position in which it is not arranged above the access opening of the at least one sharpening channel of the sharpener unit accommodated in the receiving space of the first housing part, so that insertion of a pin into the at least one sharpening channel of the sharpener unit is possible.

[0017] The first housing part and the at least one component are connectable or connected to one another via a connecting part. The device therefore comprises a connecting part which is arrangeable or arranged between the first housing part and the at least one component and which is designed to connect the first housing part to the at least one component. The connecting part therefore represents an independent or separate component of the device from the first housing part and / or the at least one component, which component, when the device is in its intended assembled state, is arranged between the first housing part and the at least one component in order to connect them to one another. The connecting part therefore represents an assembly part which can be assembled to the first housing part and / or to the at least one component in one or more assembly steps.The connecting part is therefore not a film hinge that is integrally connected to both the first housing part and the at least one component, and, as will become apparent below, is also not a single hinge defining a single pivot axis. As will also become apparent below, the connecting part is therefore detachably connectable or connected to the first housing part and / or to the at least one component, particularly in a non-damaging or non-destructive manner.

[0018] The connecting part has a first bearing interface defining a first pivot axis. The first bearing interface is configured to interact with a corresponding bearing interface on the first housing part to form a bearing of the connecting part on the first housing part that can pivot about the first pivot axis. The first bearing interface of the connecting part thus comprises one or more active sections, explained in more detail below, which define a first pivot axis and are configured to interact with corresponding active sections of a bearing interface on the first housing part to form a pivotally movable bearing of the connecting part on the first housing part. The bearing interface or the corresponding active sections on the first housing part can be arranged or formed on the base body and / or on the attachment body of the first housing part.The bearing interface or the corresponding active sections on the first housing part can therefore be the functional areas of the base body and / or the attachment body of the first housing part mentioned above.

[0019] The connecting part additionally has a second bearing interface defining a second pivot axis. The second bearing interface is designed to interact with a corresponding bearing interface on the at least one component to form a bearing of the connecting part on the at least one component that can pivot about the second pivot axis. The second bearing interface of the connecting part therefore comprises one or more active sections, explained in more detail below, which define a second pivot axis and are designed to interact with corresponding active sections of a bearing interface on the at least one component to form a pivotable bearing of the connecting part on the at least one component. The bearing interface or the corresponding active sections on the at least one component can orIf the at least one component is a second housing part, they can be arranged or formed on the base body and / or on the attachment body of the second housing part. The bearing interface or the corresponding active sections on the second housing part can therefore be the functional areas of the base body and / or the attachment body of the second housing part mentioned above.

[0020] The connecting part is therefore not designed as a single hinge known from the prior art, defining a single pivot axis, since it defines two pivot axes via two bearing interfaces. As explained below by way of example, it is thus possible to integrate the connecting part into the device in a compact manner, so that in certain pivot positions of the at least one component relative to the housing part, it protrudes little or not at all beyond the outer circumference of the device.

[0021] In addition to the second bearing interface defining the second pivot axis, the connecting part can have at least one further bearing interface configured to interact with a corresponding bearing interface on at least one further component, forming a bearing of the connecting part on the at least one further component that is pivotable about the third pivot axis. All statements relating to the second bearing interface apply analogously.

[0022] The device is therefore able to realize corresponding degrees of freedom of pivoting movement by means of the connecting part arranged between the first housing part and the at least one component without the provision of a film hinge known from the prior art described at the outset, which is connected in one piece to both the first housing part and the at least one component, and without the provision of a known single hinge.

[0023] This is an improved device compared to the state of the art described at the beginning.

[0024] The first pivot axis and / or the second pivot axis can be aligned at an angle to the at least one sharpening channel axis of the at least one sharpening unit accommodated in the receiving space of the first housing part. In particular, the first pivot axis and the second pivot axis can be aligned in an angular range between 70 and 110°, in particular between 80 and 100°, further in particular between 85 and 95°, optionally of 90°, with respect to the at least one sharpening channel axis. The at least one sharpening channel axis and the two pivot axes are therefore typically differently aligned, in particular (substantially) orthogonal to one another, spatial axes.

[0025] The first pivot axis and the second pivot axis can be arranged or aligned in the same spatial plane. In particular, the first pivot axis and the second pivot axis can be arranged or aligned parallel in a common spatial plane. This represents a preferred design variant because it is comparatively easy to implement. However, it is also conceivable for the first pivot axis and the second pivot axis to be arranged or aligned in different spatial planes. In particular, the first pivot axis and the second pivot axis can be arranged or aligned in different parallel spatial planes.

[0026] The first bearing interface of the connecting part can, as indicated above, be configured to interact with the corresponding bearing interface on the first housing part, forming a detachable connection between the connecting part and the corresponding bearing interface on the first housing part, in particular in a manner that is non-damaging or non-destructive. The first bearing interface of the connecting part can thus be detachably coupled to the first housing part, in particular in a manner that is non-damaging or non-destructive. This makes it possible, for example, to replace the connecting part in the event of damage and is therefore expedient with regard to long-term and thus sustainable use of the device.

[0027] Alternatively or additionally, as also indicated above, the second mounting interface of the connecting part can be configured to interact with the corresponding mounting interface on the at least one component, forming a detachable connection between the connecting part and the corresponding mounting interface on the at least one component, in particular in a non-damaging or non-destructive manner. The second mounting interface of the connecting part can thus be detachably coupled to the at least one component, in particular in a non-damaging or non-destructive manner. This also makes it possible to replace the connecting part in the event of damage and is therefore expedient with regard to long-term and thus sustainable use of the device.

[0028] By means of appropriately detachable connections, it is possible to change the configuration of the device as required, for example by replacing a component designed as a second housing part with another second housing part, which may, for example, have a different tip unit. Likewise, a component designed as a second housing part can be replaced by a component designed as a cover part. Likewise, housing parts can be replaced by housing parts of different dimensions, different colors, different surfaces, etc. Analogously, cover parts can be replaced by cover parts of different dimensions, different colors, different surfaces, etc. The device can therefore be designed in a modular manner so that a user can configure it themselves as required by assembling housing parts and / or cover parts accordingly.

[0029] The described interaction of the bearing interfaces of the connecting part with the respective corresponding bearing interface on the first housing part and / or on the at least one component can be realized, for example, as follows: In a first exemplary configuration, the first bearing interface of the connecting part can be configured to interact positively and / or non-positively with the corresponding bearing interface on the first housing part, forming a bearing of the connecting part on the first housing part that is pivotable about the first pivot axis. The first bearing interface of the connecting part can thus comprise one or more active sections configured to interact positively and / or non-positively with one or more corresponding active sections on the first housing part.In this first exemplary configuration, the second mounting interface of the connecting part can be configured to interact positively and / or non-positively and / or materially with the corresponding mounting interface on the at least one component, forming a mounting of the connecting part on the at least one component that can pivot about the second pivot axis. The second mounting interface of the connecting part can thus comprise one or more active sections configured to interact positively and / or non-positively and / or materially with one or more corresponding active sections on the at least one component. It is therefore also possible for the connecting part to be materially connected to the at least one component via the second mounting interface.The second bearing interface can therefore optionally also be designed as a film hinge; however, in contrast to the prior art described at the outset, the connecting part in this variant is not materially connected to both the first housing part and the at least one component, but only to the at least one component.

[0030] In a second exemplary configuration, the first bearing interface of the connecting part can interact with the corresponding bearing interface on the first housing part in a form-fitting and / or force-fitting and / or material-fitting manner, forming a bearing of the connecting part on the first housing part that can pivot about the first pivot axis. The first bearing interface of the connecting part can thus comprise one or more active sections that are configured to interact with one or more corresponding active sections on the first housing part in a form-fitting and / or force-fitting and / or material-fitting manner. It is therefore also possible for the connecting part to be connected to the first housing part in a material-fitting manner via the first bearing interface.The first bearing interface can therefore optionally also be designed as a film hinge; however, in contrast to the prior art described above, the connecting part in this variant is not materially connected to both the first housing part and the at least one component, but only to the first housing part. The second bearing interface of the connecting part can be configured in this second exemplary configuration to interact positively and / or non-positively with the corresponding bearing interface on the at least one component, forming a bearing of the connecting part on the at least one component that is pivotable about the second pivot axis.The second bearing interface of the connecting part can thus comprise one or more active sections which are designed to interact in a form-fitting and / or force-fitting manner with one or more corresponding active sections on the at least one component.

[0031] From the above description of the exemplary configurations, it follows that the connecting part can be connected at one end to the first housing part or the at least one component in a form-fitting and / or force-fitting and / or material-fitting manner, and at the other end to the first housing part or the at least one component in a form-fitting and / or force-fitting manner. The overall configuration of the device thus allows for a high degree of variability with regard to the connection of the connecting part to the first housing part and / or the at least one component.

[0032] If the connecting part is connected at one end via a material-fit bearing interface to a corresponding bearing interface of the first housing part or of the at least one component and at the other end is connected in a form-fitting and / or force-fitting manner, i.e. via a hinge element, to a corresponding bearing interface of the at least one component or of the first housing part, thus providing a combination of a material-fit film hinge and a form-fitting and / or force-fitting hinge element, the hinge element can serve to protect the film hinge from damage, as it can become loose during certain movements, in particular twisting of the at least one component relative to the first housing part, so that no further force or moment effect on the film hinge is possible and the film hinge is thus protected.

[0033] In general, therefore, the connecting part can have a base body, wherein the first bearing interface can be arranged or formed at a first free end of the base body and the second bearing interface can be arranged or formed at a second free end of the base body opposite the first free end.

[0034] The connecting part can also be designed in several parts, thus having a multi-part base body, wherein a first connecting part section or a first base body section and a second connecting part section or a second base body section are connected to one another in an articulated manner via a hinge, this hinge can also be a film hinge. The two connecting part sections or base body sections can thus be pivotally connected to one another about their own pivot axis, which is typically aligned parallel to the first and second pivot axes. The first bearing interface of the connecting part can be arranged or formed on a first connecting part or base body section, and the second bearing interface of the connecting part can be arranged or formed on a second connecting part or base body section.

[0035] The base body of the connecting part can, for example, have a plate-like or plate-shaped basic shape. In multi-part designs, the first and / or second connecting part or base body section can have a plate-like or plate-shaped basic shape.

[0036] In a specific embodiment, the base body of the connecting part can be H-like or H-shaped. Accordingly, in embodiments in which the base body of the connecting part has a plate-like or plate-shaped basic shape, it does not necessarily have to have a rectangular geometry. The first bearing interface can be arranged or formed on or in the region of the upper vertical sections or legs, and the second bearing interface can be arranged or formed on or in the region of the lower vertical sections or legs. In particular, corresponding hinge elements or form-fitting and / or frictional locking elements, which are explained in more detail below, can be arranged or formed on the respective opposing inner sides of the respective long sections or legs.

[0037] If positive and / or non-positive connection types are provided, the first mounting interface of the connecting part can thus comprise a hinge element. The corresponding mounting interface on the first housing part can comprise a corresponding hinge element. The two mounting interfaces can interact to form a pivot hinge that forms or defines the first pivot axis, so that the connecting part is pivotably mounted on the first housing part (and vice versa).

[0038] The hinge element of the first bearing interface of the connecting part can be or comprise a form-fitting and / or force-fitting element. The corresponding hinge element of the corresponding bearing interface on the first housing part can be or comprise a form-fitting and / or force-fitting element. A form-fitting and / or force-fitting element can be formed, for example, by a projection, in particular a pin- or peg-like or -shaped projection. Alternatively or in addition to corresponding projections, a form-fitting and / or force-fitting element can also be formed, for example, as a bolt or strip element extending (continuously) between two wall sections of the respective bearing interface or can comprise such a projection. A form-fitting and / or force-fitting element corresponding thereto can be formed, for example, by a receptacle, in particular a recess- or depression-like receptacle, for such a projection.A reverse configuration is also conceivable.

[0039] Analogously, the second mounting interface of the connecting part can comprise a hinge element. The corresponding mounting interface on the at least one component can comprise a corresponding hinge element. The two mounting interfaces can interact to form a pivot hinge that forms or defines the second pivot axis, so that the connecting part is pivotably mounted on the at least one component (and vice versa).

[0040] The hinge element of the second bearing interface of the connecting part can be or comprise a form-fitting and / or force-fitting element. The corresponding hinge element of the corresponding bearing interface on the at least one component can be or comprise a corresponding form-fitting and / or force-fitting element. A form-fitting and / or force-fitting element can be formed, for example, by a projection, in particular a pin- or peg-like or -shaped projection. Alternatively or in addition to corresponding projections, a form-fitting and / or force-fitting element can also be formed, for example, as a bolt or strip element extending (continuously) between two wall sections of the respective bearing interface or can comprise such a projection. A form-fitting and / or force-fitting element corresponding thereto can be formed, for example, by a receptacle, in particular a recess- or depression-like receptacle, for such a projection.Here, too, a reverse configuration is conceivable.

[0041] The pivotable mounting of the at least one component on the first housing part can involve pivoting the at least one component relative to the first housing part through a defined angular range. Specifically, the at least one component can be pivotably mounted relative to the first housing part, for example, through an angle of at least 150°, in particular of at least 160°, in particular of at least 170°, in particular of at least 180°. The connecting part enables, in particular, smooth pivoting of the at least one component through an angle of at least 170°, in particular of at least 180° or more, which is not possible with the film hinges known from the prior art described above, or not possible in the desired smooth manner.

[0042] In order to give the device a visually appealing appearance and to keep the space occupied by the device as compact as possible, the bearing interface of the first housing part corresponding to the first bearing interface of the connecting part can be arranged or designed to be radially inwardly offset with respect to the pointed channel axis relative to an outer circumference of the first housing part. In particular, the bearing interface of the first housing part corresponding to the first bearing interface of the connecting part can be arranged or designed within a recess or depression in the first housing part that is radially inwardly offset with respect to the pointed channel axis and is optionally chamber-like or shaped. The recess or depression can be arranged or designed on or in the base body and / or on or in the attachment body of the first housing part.The same applies to the bearing interface of the at least one component corresponding to the second bearing interface of the connecting part; thus, the bearing interface of the at least one component can also be arranged or formed within a corresponding, optionally chamber-like or chamber-shaped, recess or depression of the at least one component. The configuration of the connecting part with two bearing interfaces, each defining a pivot axis, thus enables a very compact and visually appealing design of the device. The provision of the connecting part, in contrast to conventional film hinges or conventional single hinges, thus enables all bearing interfaces for coupling the connecting part to the first housing part and the at least one component to be arranged in a very compact and visually appealing manner.

[0043] If the corresponding bearing interface of the first housing part and / or the corresponding bearing interface of the at least one component is arranged or formed within a recess or depression of the first housing part that is offset inwards with respect to the tip channel axis, the connecting part can be arranged or arranged in at least one pivoting position, in particular completely, in the recess or depression, wherein it does not protrude, or does not protrude by more than 2 mm, in particular not by more than 1.75 mm, further in particular not by more than 1.5 mm, further in particular not by more than 1.25 mm, further in particular not by more than 1 mm, beyond the outer circumference of the device or of the first housing part or of the at least one component in the radial direction with respect to the tip channel axis.

[0044] In order to be able to provide a user of the device with haptic feedback during the typically manual pivoting of the at least one component relative to the first housing part, at least one structural element, optionally made of an elastically reversibly deformable material or an elastically reversibly deformable material structure, can be arranged or formed on the connecting part and / or on the first housing part and / or on the at least one component. The at least one structural element can mechanically dampen a pivoting movement so that it can be carried out in a more controlled manner. Specifically, a corresponding structural element can be designed as, for example, pin-like or- shaped, highlighting on the connecting part and / or on the first housing part and / or on the at least one component, in particular on an exposed outer surface of at least one of the said parts, may be arranged or formed, in particular in such a way that it causes a mechanical damping effect when the connecting part is pivoted, for example by deformation.

[0045] With the same objective, at least one stop element can be arranged or formed on the connecting part and / or on the first housing part and / or on the at least one component, which defines a pivoting-open position beyond which further pivoting is not possible. A corresponding stop element can, for example, be arranged or aligned such that pivoting of the at least one component relative to the first housing part is not possible beyond an angle of more than 190°.

[0046] For all embodiments, the first housing part, in particular an attachment body of the first housing part, is designed with or can comprise at least one securing element which, in the described first pivot position in which the at least one component is arranged above an access opening of the at least one sharpening channel of the sharpener unit accommodated in the receiving space of the first housing part, so that insertion of a pin into the at least one sharpening channel of the sharpener unit is not possible, cooperates with at least one corresponding securing element on the at least one component in order to secure the at least one component in the first pivot position. A corresponding securing element can be a positive and / or non-positive locking element which, for example,as a projection contour protruding from the exposed upper side of the first housing part, in particular the exposed upper side of the attachment body, or a corresponding receptacle for such a projection contour. A corresponding projection contour can be designed, for example, as a continuous, quasi-continuous, or discontinuous profile; a corresponding receptacle can be designed, for example, as a corresponding recess or depression.

[0047] For manufacturing and thus economic reasons, the device, ie the individual parts comprising it, ie the first housing part, the connecting part, and the at least one component, can expediently be made at least partially, in particular entirely, of a plastic material, in particular a thermoplastic material, e.g., ABS, PA, PE, PP, PS. Of course, different parts can be made of different plastic materials.

[0048] The invention further relates to a connecting part for a device according to the first aspect of the invention. The connecting part has a first bearing interface defining a first pivot axis, which is configured to interact with a corresponding bearing interface on a first housing part of the device to form a bearing of the connecting part on the first housing part that can pivot about the first pivot axis, and a second bearing interface defining a second pivot axis, which is configured to interact with a corresponding bearing interface on at least one component of the device to form a bearing of the connecting part on the at least one component that can pivot about the second pivot axis. In connection with the connecting part, all statements made in connection with the device generally apply analogously.

[0049] The invention will be explained in more detail below using exemplary embodiments in the drawings. In the drawings: Fig. 1 - 4 different views of a device according to a first embodiment; Fig. 5 - 8 different views of a device according to a second embodiment; Fig. 9 - 10 different views of a device according to a third embodiment; Fig. 11 - 12 different views of a device according to a fourth embodiment; and Fig. 13 - 15 different views of a device according to a fifth embodiment.

[0050] The figures show different views of a device 1 according to different embodiments.

[0051] Specifically, the Fig. 1 - 4 different views of a device 1 according to a first embodiment in three perspective representations ( Fig. 1, Fig. 3, Fig. 4) and an exploded view ( Fig. 2), the Fig. 5 - 8 different views of a device 1 according to a second embodiment in three perspective representations ( Fig. 5, Fig. 7, Fig. 8) and an exploded view ( Fig. 6), the Fig. 9, Fig. 10 different views of a device 1 according to a third embodiment in two perspective views, the Fig. 11, Fig. 12 different views of a device 1 according to a fourth embodiment in a perspective view ( Fig. 11) and in an exploded view ( Fig. 12) and the Fig. 13 - 15 different views of a device 1 according to a fifth embodiment in two perspective representations ( Fig. 13, Fig. 15) and an exploded view ( Fig. 14).

[0052] In all embodiments, the device 1 is configured for sharpening or shaping at least one pencil. The device 1 can, in principle, be used to sharpen or shape any type of sharpenable pencil, i.e., in particular, a painting, cosmetic, writing, or drawing pencil. Specifically, the device 1 can be used, in particular, to sharpen or shape the lead of a pencil, which may be coated with a coating material.

[0053] The figure shows that the device 1 can be configured as a so-called double or multiple sharpener; however, designs as a single sharpener are equally conceivable.

[0054] The device 1 therefore comprises at least a first housing part 2, which has or delimits a receiving space for receiving at least one sharpening unit. The sharpening unit is not fully visible in the figures, apart from the sharpening channel 3 and the access opening 4; however, it is known to a person skilled in the art how a corresponding sharpening unit is received in a corresponding receiving space. The spatial volume of the first housing part 2 delimited by the receiving space is partly occupied by a sharpening unit which is received at least partially, if necessary completely, in the receiving space. The spatial volume not occupied by the sharpening unit and is therefore free is designed as a reservoir for receiving material removed during the sharpening or shaping of pencils. The receiving space orThe receiving volume of the first housing part 2 thus serves both to at least partially accommodate at least one sharpening unit and to accommodate material removed during a sharpening process by means of the at least one sharpening unit. The sharpening unit has at least one, typically funnel-like or funnel-shaped, sharpening channel 3 defining a sharpening channel axis A1. The sharpening channel 3 is accessible via an access opening 4. The sharpening unit further comprises at least one sharpening element, in particular a blade-shaped or cutting edge-shaped element, accessible via the access opening 4 into the at least one sharpening channel 3.

[0055] The first housing part 2 can be constructed in one or more parts. In the multi-part design shown as an example in the figures, the first housing part 2 can comprise a base body 5 that is open on one side and an attachment body 6 that can be arranged or is arranged on the base body 5, e.g., by being placed on it. The attachment body 6 has one or more openings 7, which, when arranged as intended on the base body 5, are aligned with the respective access opening(s) 4 in the respective pointed channel(s) 3.

[0056] The figure shows that the base body 5 can have a cylindrical or cylinder-like, a prismatic or prism-like basic shape, or a polygonal, e.g., triangular, pentagonal, etc., basic shape. Furthermore, the figure shows that the attachment body 6 can have a plate-like or plate-shaped basic shape. One or more functional areas 8, explained in more detail below, can be arranged or formed on both the base body 5 and the attachment body 6.

[0057] All statements in connection with the first housing part 2 apply analogously to each further housing part of the device 1; as can be seen from the embodiments according to the Fig. 1 to 12, the device 1 can comprise two housing parts 2, which can differ, for example, in the number of pointed channels.

[0058] The device 1 therefore comprises, in addition to the first housing part 2, at least one component 9; the component 9 can be, for example, the Fig. 1 - 12 shown further housing part or, as in the Fig. 13 - 15, a cover part associated with the first housing part 2.

[0059] In all embodiments, and therefore regardless of its specific design, the component 9 is pivotally mounted on the first housing part 2, as can be seen, for example, from the representative Fig. 3, Fig. 4. The first housing part 2 and the component 9 can thus be moved into different orientations and / or positions relative to each other via corresponding pivoting movements of the component 9 relative to the first housing part 2. An example in Fig. The first orientation and / or position shown in Figure 1 can be one in which no access is possible to the at least one sharpening channel 3 of the at least one sharpening unit accommodated in the receiving space of the first housing part 2, so that sharpening of a pencil with the sharpening unit accommodated in the first housing part 2 is not possible. The same applies to sharpening of a pencil with the sharpening unit accommodated in the second housing part, which is also not possible in the first orientation and / or position. The same applies to embodiments with a cover part instead of a second housing part. An example shown in Fig. The second orientation and / or position shown in Figure 4 can be one in which access to the at least one sharpening channel of the at least one sharpening unit accommodated in the receiving space of the first housing part 2 is possible, so that sharpening of a pencil with the sharpening unit accommodated in the first housing part 2 is possible. The same applies to sharpening of a pencil with the sharpening unit accommodated in the second housing part, which is also not possible in the second orientation and / or position. The same applies to embodiments with a cover part instead of a second housing part.

[0060] The component 9 can therefore be pivoted into a first pivot position in which it is arranged above an access opening 4 of the at least one sharpening channel 3 of the sharpener unit accommodated in the receiving space of the first housing part, so that insertion of a pin into the at least one sharpening channel 3 of the sharpener unit is not possible, and pivoted into a second pivot position in which it is not arranged above the access opening 4 of the at least one sharpening channel 3 of the sharpener unit accommodated in the receiving space of the first housing part 2, so that insertion of a pin into the at least one sharpening channel 3 of the sharpener unit is possible.

[0061] In all exemplary embodiments, the first housing part 2 and the component 9 are connectable or connected to one another via a connecting part 10. The device 1 thus comprises a connecting part 10 that is arrangeable or arranged between the first housing part 2 and the component 9 and is designed to connect the first housing part 2 to the component 9. The connecting part 10 represents an independent or separate component of the device 1 from the first housing part 2 and / or the component 9, which component, in the properly assembled state of the device 1, is arranged between the first housing part 2 and the component 9 in order to connect them to one another. The connecting part 10 thus represents an assembly part that can be mounted on the first housing part 2 and / or the component 9 in one or more assembly steps.The connecting part 10 is therefore not a film hinge that is integrally connected to both the first housing part 2 and the component 9, nor is it a single hinge defining a single pivot axis. As will become apparent below, the connecting part 10 can therefore be detachably connected to the first housing part 2 and / or the component 9, particularly without damage or destruction.

[0062] The connecting part 10 has a first bearing interface 11 defining a first pivot axis S1. The first bearing interface 11 is designed to interact with a corresponding bearing interface 12 on the first housing part 2 to form a bearing of the connecting part 10 on the first housing part 2 that can pivot about the first pivot axis S1. The first bearing interface 11 of the connecting part 10 therefore comprises one or more active sections, explained in more detail below, which define a first pivot axis S1 and are designed to interact with corresponding active sections of a bearing interface 12 on the first housing part 2 to form a pivotally movable bearing of the connecting part 10 on the first housing part 2. As can be seen from the figure, the bearing interface 12 orThe corresponding active sections on the first housing part 2 can be arranged or formed on the base body 5 and / or on the attachment body 6 of the first housing part 2. The bearing interface 12 or the corresponding active sections on the first housing part 2 can thus be the functional areas of the base body 5 and / or the attachment body 6 of the first housing part 2 mentioned above.

[0063] The connecting part 10 also has a second bearing interface 13 defining a second pivot axis S2. The second bearing interface 13 is designed to interact with a corresponding bearing interface 14 on the component 9 to form a bearing of the connecting part 10 on the component 9 that can pivot about the second pivot axis S2. The second bearing interface 13 of the connecting part 10 therefore comprises one or more active sections, explained in more detail below, which define a second pivot axis S2 and are designed to interact with corresponding active sections of a bearing interface 14 on the component 9 to form a pivotable bearing of the connecting part 10 on the component 9. As can be seen from the figure, the bearing interface 14 orThe corresponding active sections on component 9, if component 9 is a second housing part, can be arranged or formed on the base body 5 and / or on the attachment body 6 of the second housing part. The bearing interface 14 or the corresponding active sections on the second housing part can thus be the functional areas of the base body 5 and / or the attachment body 6 of the second housing part mentioned above.

[0064] The device 1 is therefore able to realize corresponding degrees of freedom of pivoting movement by means of the connecting part 10 arranged between the first housing part 2 and the component 9 without the provision of a film hinge known from the prior art described at the outset, which is connected in one piece to both the first housing part 2 and the component 9.

[0065] From the figure, it can be seen that the first pivot axis S1 and / or the second pivot axis S2 can be aligned at an angle to the sharpening channel axis A1 of the at least one sharpening unit accommodated in the receiving space of the first housing part 2. In particular, the first pivot axis S1 and the second pivot axis S2 can be aligned in an angular range between 70 and 110°, in particular between 80 and 100°, further in particular between 85 and 95°, optionally of 90°, with respect to the sharpening channel axis A1. The sharpening channel axis A1 and the two pivot axes S1, S2 are therefore typically differently aligned, in particular (essentially) orthogonal to one another, spatial axes.

[0066] The figures also show that the first pivot axis S1 and the second pivot axis S2 can be arranged or aligned in the same spatial plane. In particular, the figures show by way of example that the first pivot axis S1 and the second pivot axis S2 can be arranged or aligned in parallel in a common spatial plane. This represents a structurally preferred variant because it is comparatively easy to implement. However, it is also conceivable for the first pivot axis S1 and the second pivot axis S2 to be arranged or aligned in different spatial planes. In particular, the first pivot axis S1 and the second pivot axis S2 can be arranged or aligned in different parallel spatial planes.

[0067] The first bearing interface 11 of the connecting part 10 can, as indicated above, be configured to interact with the corresponding bearing interface 12 on the first housing part 2, forming a detachable connection between the connecting part 10 and the corresponding bearing interface 12 on the first housing part 2, in particular in a manner that is non-damaging or non-destructive. The first bearing interface 11 of the connecting part 10 can thus be detachably coupled to the first housing part 2, in particular in a manner that is non-damaging or non-destructive. This makes it possible, for example, to replace the connecting part 10 in the event of damage and is therefore expedient with regard to long-term and thus sustainable use of the device 1.

[0068] Alternatively or additionally, the second bearing interface 13 of the connecting part 10, as also indicated above, can be configured to interact with the corresponding bearing interface 14 on the component 9, forming a detachable connection between the connecting part 10 and the corresponding bearing interface 14 on the component 9, in particular in a manner that is non-damaging or non-destructive. The second bearing interface 13 of the connecting part 10 can thus be detachably coupled to the component 9, in particular in a manner that is non-damaging or non-destructive. This also makes it possible to replace the connecting part 10 in the event of damage and is therefore expedient with regard to long-term and thus sustainable use of the device 1.

[0069] The described interaction of the bearing interfaces 11, 13 of the connecting part 10 with the respective corresponding bearing interface 12, 14 on the first housing part 2 and / or on the component 9 can be realized, for example, as follows: In an exemplary configuration according to the embodiments of the Fig. 1 - 8 and the Fig. 11 - 15, the first bearing interface 11 of the connecting part 10 can be configured to interact in a form-fitting and / or force-fitting manner with the corresponding bearing interface 12 on the first housing part 2, forming a bearing of the connecting part 10 on the first housing part 2 that can pivot about the first pivot axis S1. The first bearing interface 11 of the connecting part 10 here comprises one or more active sections that are configured to interact in a form-fitting and / or force-fitting manner with one or more corresponding active sections on the first housing part 2. The second bearing interface 13 of the connecting part 10 is, in this first exemplary configuration, likewise configured to interact in a form-fitting and / or force-fitting manner with the corresponding bearing interface 14 on the component 9, forming a bearing of the connecting part 10 on the component 9 that can pivot about the second pivot axis S2.The second bearing interface 13 of the connecting part 10 thus also comprises one or more active sections which are designed to interact in a form-fitting and / or force-fitting manner with one or more corresponding active sections on the component 9.

[0070] In an alternative configuration according to the embodiment of the Fig. 9, Fig. 10, Fig. 15, the first bearing interface 11 of the connecting part 10 is likewise configured to interact in a form-fitting and / or force-fitting manner with the corresponding bearing interface 12 on the first housing part 2, forming a bearing of the connecting part 10 on the first housing part 2 that is pivotable about the first pivot axis S1. Here, too, the first bearing interface 11 of the connecting part 10 comprises one or more active sections that are configured to interact in a form-fitting and / or force-fitting manner with one or more corresponding active sections on the first housing part 2. However, in this alternative exemplary configuration, the second bearing interface 13 of the connecting part 10 is configured to interact in a material-fitting manner with the corresponding bearing interface 14 on the component 9, forming a bearing of the connecting part 10 on the component 9 that is pivotable about the second pivot axis S2.The second bearing interface 13 of the connecting part 10 thus comprises one or more active sections that are configured to cooperate in a materially bonded manner with one or more corresponding active sections on the component 9. It is therefore possible for the connecting part 10 to be connected in a materially bonded manner to the component 9 via the second bearing interface 13. The second bearing interface 13 can thus also be designed as a film hinge; however, in contrast to the prior art described above, the connecting part 10 in this variant is not connected in a materially bonded manner to both the first housing part 2 and the component 9, but only to the component 9.

[0071] A reverse configuration is also conceivable; thus, the connecting part 10 can be connected to the first housing part 2 in a material-locking manner via the first bearing interface 11 and can be coupled to the component 9 in a form-fitting and / or force-fitting manner via the second bearing interface 13.

[0072] From the above description of the exemplary configurations, it follows that the connecting part 10 can be connected at one end to the first housing part 2 or the component 9 in a form-fitting and / or force-fitting and / or material-fitting manner, and at the other end can only be connected to the first housing part 2 or the component 9 in a form-fitting and / or force-fitting manner. The overall configuration of the device 1 thus allows for a high degree of variability with regard to the connection of the connecting part 10 to the first housing part 2 and the component 9.

[0073] From the figure, it is therefore generally apparent that the connecting part 10 can have a base body 15, wherein the first bearing interface 11 can be arranged or formed at a first free end of the base body 15 and the second bearing interface 13 can be arranged or formed at a second free end of the base body 15 opposite the first free end.

[0074] The base body 15 of the connecting part 10 is shown in the figures as an example with a plate-like or plate-shaped basic shape.

[0075] In a version according to the embodiment Fig. 5 - 8, the base body 15 is H-like or H-shaped. Accordingly, in embodiments in which it has a plate-like or plate-shaped basic shape, the base body 15 does not necessarily have to have a rectangular geometry. In the exemplary embodiment, the first bearing interface 11 is arranged or formed on or in the region of the upper vertical sections or legs, and the second bearing interface 13 is arranged or formed on or in the region of the lower vertical sections or legs. In particular, corresponding hinge elements or form-fitting and / or frictional locking elements, explained in more detail below, can be arranged or formed on the respective opposing inner sides of the respective long sections or legs.

[0076] If positive and / or non-positive connection types are provided for connecting the connecting part 10 to the first housing part 2 and / or the component 9, the first bearing interface 11 of the connecting part 10 can thus comprise a hinge element 16. The corresponding bearing interface 12 on the first housing part 2 can comprise a corresponding hinge element 17. The two bearing interfaces 11, 12 can interact to form a pivot hinge forming or defining the first pivot axis S1, so that the connecting part 10 is pivotably mounted on the first housing part 2 (and vice versa).

[0077] From the corresponding figure, it is clear that the hinge element 16 of the first bearing interface 11 of the connecting part 10 can be or comprise a form-locking and / or frictional locking element (not further specified). The corresponding hinge element 17 of the corresponding bearing interface 12 on the first housing part 2 can be or comprise a form-locking and / or frictional locking element (not further specified). It is clear that a form-locking and / or frictional locking element on the side of the first housing part 2 can be formed by a projection, in particular a pin-like or peg-like projection (cf., for example, Fig. 2). Alternatively or in addition to corresponding projections, a form-fitting and / or force-locking element can also be designed, for example, as a bolt or strip element extending (continuously) between two wall sections of the respective bearing interface 11, 13 or can comprise such a element (cf. Fig. 14). It is also evident from the corresponding figures that a corresponding form-fitting and / or frictional locking element can be formed, for example, by a recess-like or recess-like receptacle for such a projection (cf. ibid.). A reverse configuration is also conceivable.

[0078] Analogously, the second mounting interface 13 of the connecting part 10 can comprise a hinge element 18. The corresponding mounting interface 14 on the component 9 can comprise a corresponding hinge element 19. The two mounting interfaces 13, 14 can interact to form a pivot hinge that forms or defines the second pivot axis S2, so that the connecting part 10 is pivotably mounted on the component 9 (and vice versa).

[0079] From the corresponding figure, it is clear that the hinge element 18 of the second bearing interface 13 of the connecting part 10 can be or comprise a non-described form-fitting and / or force-locking element. The corresponding hinge element 19 of the corresponding bearing interface 13 on the component 9 can be or comprise a non-described form-fitting and / or force-locking element. It is clear that a form-fitting and / or force-locking element on the part of the component 9 can be formed, for example, by a projection, in particular a pin-like or peg-like projection (cf., for example, Fig. 2). Alternatively or in addition to corresponding projections, a form-fitting and / or force-locking element can also be designed, for example, as a bolt or strip element extending (continuously) between two wall sections of the respective bearing interface or can comprise such a element (cf. Fig. 14). It is also evident from the corresponding figures that a corresponding form-fitting and / or frictional locking element can be formed, for example, by a recess-like or recess-like receptacle for such a projection (cf. ibid.). A reverse configuration is also conceivable.

[0080] The figures further show that a pivotable mounting of the component 9 on the first housing part 2 involves pivoting the component 9 relative to the first housing part 2 through a defined angular range. Specifically, the component 9 can be pivotally mounted, for example, through an angle of at least 150°, in particular of at least 160°, in particular of at least 170°, in particular of at least 180°, relative to the first housing part 2. The connecting part 10 enables, in particular, a smooth pivoting of the component 9 through an angle of at least 170°, in particular of at least 180° or more, which is not possible with the film hinges known from the prior art described at the beginning, or not possible in the desired smooth manner.

[0081] The figures further show that, in order to give the device 1 a visually appealing appearance and to keep the volume occupied by the device 1 as compact as possible, the bearing interface 12 of the first housing part 2 corresponding to the first bearing interface 11 of the connecting part 10 can be arranged or formed radially inwardly offset with respect to the pointed channel axis A1 relative to an outer circumference of the first housing part 2. As can be seen, the bearing interface 12 of the first housing part 2 corresponding to the first bearing interface 11 of the connecting part 10 can be arranged or formed within a recess 20 or depression of the first housing part 2 which is radially inwardly offset with respect to the pointed channel axis A1 and which may be chamber-like or shaped, and which can be arranged or formed on or in the base body 5 and / or on or in the attachment body 6 of the first housing part 2.Obviously, the same applies to the bearing interface 14 of the component 9 corresponding to the second bearing interface 13 of the connecting part 10; thus, this bearing interface 14 of the component 9 can also be arranged or formed within a corresponding, optionally chamber-like or chamber-shaped, recess 21 or depression of the component 9 (cf., for example, . Fig. 2 or Fig. 14).

[0082] Based on the Fig. 1, Fig. 5, Fig. 9 and Fig.13 shows that, if the bearing interface 12 of the first housing part 2 and the bearing interface 14 of the component 9 are arranged or formed within a recess or depression offset inward with respect to the tip channel axis A1, the connecting part 10 can be arranged or arranged in at least one pivoted position, in particular completely, in the respective recess or depression. The connecting part 10 then protrudes not or not by more than 2 mm, in particular not by more than 1.75 mm, furthermore in particular not by more than 1.5 mm, furthermore in particular not by more than 1.25 mm, furthermore in particular not by more than 1 mm, beyond the outer circumference of the first housing part 2 and the component 9 in the radial direction with respect to the tip channel axis A1.

[0083] For all exemplary embodiments, in order to be able to provide a user of the device 1 with haptic feedback during the pivoting of the component 9 relative to the first housing part 2, which is typically carried out manually, at least one structural element, optionally made of an elastically reversibly deformable material or an elastically reversibly deformable material structure, can be arranged or formed on the connecting part 10 and / or on the first housing part 2 and / or on the component 9. The at least one structural element can equally mechanically dampen a pivoting movement so that it can be carried out in a more controlled manner. Specifically, a corresponding structural element can be designed as, for example, pin-like or- shaped, highlighting on the connecting part 10 and / or on the first housing part 2 and / or on the component 9, in particular on an exposed outer surface of at least one of the said parts, may be arranged or formed, in particular in such a way that it causes a mechanically damping effect when the connecting part 10 is pivoted, for example by deformation.

[0084] For the same purpose, at least one stop element can be arranged or formed on the connecting part 10 and / or on the first housing part 2 and / or on the component 9, which defines a pivoting position beyond which further pivoting is not possible. A corresponding stop element can, for example, be arranged or aligned such that pivoting of the component 9 relative to the first housing part 2 is not possible beyond an angle of more than 190°.

[0085] For all exemplary embodiments, it further applies that the first housing part 2, in particular the attachment body 6 of the first housing part 2, is designed with or can comprise at least one securing element 22, which in the described first pivot position, in which the component 9 is arranged above an access opening 4 of the at least one pointed channel 3 of the sharpener unit accommodated in the receiving space of the first housing part, so that insertion of a pin into the at least one pointed channel 3 of the sharpener unit is not possible, cooperates with at least one corresponding securing element 23 on the component 9 in order to secure the component 9 in the first pivot position. A corresponding securing element 22, 23 can be a positive and / or non-positive locking element, which e.g.as a projection contour protruding from the exposed upper side of the first housing part 2, in particular the exposed upper side of the attachment body 6, or a corresponding receptacle for such a projection contour. A corresponding projection contour can be designed, for example, as a continuous, quasi-continuous, or discontinuous profile; a corresponding receptacle can be designed, for example, as a corresponding recess or depression.

[0086] For manufacturing and thus economic reasons, the device 1, i.e., the individual parts comprising it, i.e., the first housing part 2, the connecting part 10, and the component 9, can expediently be made at least partially, in particular entirely, of a single, particularly thermoplastic, plastic material, e.g., ABS, PA, PE, PP, PS. Of course, different parts can be made of different plastic materials.

[0087] Although not shown in the figures, the connecting part 10 can also be designed in several parts, thus having a multi-part base body, wherein a first connecting part section or a first base body section and a second connecting part section or a second base body section are connected to one another in an articulated manner via a hinge. The two connecting part sections or base body sections can thus be pivotally connected to one another about their own pivot axis, which is typically aligned parallel to the first and second pivot axes S1, S2. The first bearing interface 11 of the connecting part 10 can be arranged or formed on a first connecting part or base body section, and the second bearing interface 13 of the connecting part 10 can be arranged or formed on a second connecting part or base body section.

[0088] Even in multi-part designs of the connecting part 10, the first and / or second connecting part or base body section can have a plate-like or plate-shaped basic shape.

[0089] Individual, multiple or all features of one embodiment can be combined with individual, multiple or all features of at least one further embodiment.
