The invention relates to a device for sharpening at least one pencil, comprising a sharpener device which comprises at least one sharpener channel which is accessible via an insertion area for inserting a pencil to be sharpened and defines a sharpener channel axis, and a functional device which comprises at least one functional element which can be assigned or is assigned to the insertion area on the sharpener channel side.

Appropriate devices for sharpening or shaping pins, d. H. in particular writing, drawing or cosmetic pencils, are basically known from the prior art in a large number of different embodiments. An essential component of corresponding devices is a sharpener device, which is typically a sharpener device, which comprises at least one sharpener channel, which is accessible via an insertion area for inserting a pencil to be sharpened, and defines a sharpener channel axis.

Corresponding sharpening devices is often a functional device z. B. assigned in the form of a closure device, which can be assigned or assigned to the insertion functional element z. B. in the form of a closure element. The insertion can therefore be closed as required by a corresponding functional element, which z. B. is useful to prevent shavings such. B. material removed by a pen as part of a sharpening process, can leak out of the device via the sharpener channel in an undesired manner.

There is a constant need for improvement or further development of the functional or structural design of corresponding closure devices, i. H. in particular the closure elements of corresponding closure devices. In particular, corresponding closure devices or elements are required with regard to aspects such as a reliably effective closure of an insertion area on the sharpener channel side and/or the possibility of a centric insertion of pins of different configurations, i. H. in particular different diameters, with a compact design and practicable operability by a user in need of improvement or further development.

Proceeding from this, the invention is based on the object of specifying an improved device for sharpening pencils.

The object is achieved by a device for sharpening at least one pencil according to claim 1. The dependent claims relate to possible embodiments of the device.

A first aspect of the invention described herein relates to a device for sharpening or shaping at least one pencil. The device can also be referred to or considered as a pencil sharpener or pencil shaper. In principle, any pen or any pencil lead can be sharpened or shaped with the device, so that writing, drawing or cosmetic pencils are only referred to as examples.

Although the device is described below in particular as a single sharpener for sharpening a pencil, it is also conceivable that the device can be designed as a multiple sharpener for sharpening a number of pencils, in particular a number of pencils with different pencil geometries or configurations, i. H. in particular different diameters or different cross-sectional geometries.

The device includes a sharpening device. The sharpening device is set up for sharpening or shaping at least one pencil to be sharpened by means of the device. The sharpening device has at least one sharpener channel which is accessible via an in particular hollow-cylindrical insertion area. The insertion area of the sharpener channel is thus set up for inserting a pencil into the sharpener channel. The insertion area of the sharpener channel typically merges directly into the sharpener channel. The cross-sectional geometry of the sharpener channel is typically adapted at least in sections, optionally completely, to the cross-sectional geometry of a pin or pin section to be inserted into it. The spitzer channel defines a spitzer channel axis. The sharpener channel typically has a conical or frusto-conical geometry or basic shape. In the case of a conical or truncated cone-shaped geometry or basic shape of the spitzer channel, the sharpener channel axis is typically defined by the symmetry or central axis of the conical or truncated cone-shaped sharpener channel. The sharpening device also typically comprises at least one, e.g. B. knife-like or -shaped, pointed element, which for the (actual) sharpening or shaping of a pin or pin section inserted into the sharpener channel via the insertion area, d. H. typically a pen tip.

The sharpening device can have a base body. The sharpener canal, e.g. B. be arranged or formed by a corresponding recess, opening, wall structure or the like in the main body of the sharpening device. Equally, the at least one tip element can be on or in the main body of the tip be arranged or designed. The at least one sharpening element is typically arranged or designed relative to the sharpener channel in such a way that sharpening or shaping of a pencil or pencil section inserted into the sharpener channel via the insertion area, ie typically a pencil tip, is possible.

The main body of the sharpening device can have a wedge-like or wedge-shaped geometry or basic shape defined by a planar base surface and an inclined surface running obliquely thereto. With a wedge-like or wedge-shaped geometry or basic shape of the base body of the sharpener device, the sharpener channel can be arranged or formed with the sharpener channel axis extending along the base surface of the wedge-like or wedge-shaped base body of the sharpener device. In the case of a wedge-like or wedge-shaped geometry or basic shape of the basic body of the sharpening device, the sharpening element can be arranged or formed on or in the inclined surface of the wedge-like or wedge-shaped basic body of the sharpening device. The same applies to other geometries or basic shapes of the base body of the sharpening device.

As will become apparent below, the sharpening device, i. H. in particular a corresponding base body of the sharpener device, at least in sections, optionally completely, can be arranged or formed within a housing device of the device. A corresponding housing device can have a one, e.g. B. open on one side, housing (interior) space defining housing body. The sharpener, i. H. in particular, a corresponding base body of the sharpener device can be arranged or formed within the (inner) housing space defined by the housing body. A corresponding housing (interior) space is typically equally for catching a pencil or pencil section introduced into the sharpener channel via the introduction region during a sharpening or shaping process, i. H. typically a pen tip, resulting in sharp waste furnishings.

The device also includes a functional device. As follows, the functional device can in particular be designed as a closure device and correspondingly optionally referred to or considered as a closure device. If the functional device is designed as a closure device, it can be set up to close the insertion area, in particular as required.

The functional device has at least one functional element that can be assigned or is assigned to the insertion area of the sharpener channel. If the functional device is designed as a closure device, the functional element can be designed as a closure element and accordingly referred to or considered as a closure element. The at least one functional element is rotatably mounted about an axis of rotation. The at least one functional element can be transferred into at least one (first) position or rotational position by rotating about a or the axis of rotation, in which it is possible to insert a pencil to be sharpened into the insertion area on the sharpener channel. A corresponding (first) position can also be referred to or considered as an open position. In addition, the at least one functional element can be transferred into at least one further position or rotational position in which it is not possible to insert a pencil to be sharpened into the insertion area on the sharpener channel side. A corresponding (further) position can be referred to or considered as a closed position. The at least one functional element can thus be transferred into a plurality of positions or rotary positions by rotating about the axis of rotation, with at least one rotary position correlating with a position of the at least one functional element in which a pencil to be sharpened can be inserted into the insertion area. In addition, at least one further rotational position can correlate with at least one closed position of the at least one functional element, in which it is not possible to insert a pencil to be sharpened into the insertion area.

The axis of rotation can be arranged or aligned centrically or off-center (eccentrically), so that depending on the arrangement or orientation of the axis of rotation, a centric or off-center rotary bearing of the at least one functional element is possible. A centric arrangement or orientation of the axis of rotation and thus a centric rotary bearing of the at least one functional element typically provides an arrangement or orientation of the axis of rotation at an angle of 90° relative to the sharpener channel or to the sharpener channel axis. An off-center arrangement or orientation of the axis of rotation and thus an off-center rotary mounting of the at least one functional element typically provides for an arrangement or orientation of the axis of rotation at an angle greater than or less than 90° relative to the sharpener channel or to the sharpener channel axis.

The at least one functional element can - this applies in particular to embodiments of the at least one functional element with a rotationally symmetrical geometry or basic shape - therefore be mounted centrically or eccentrically with respect to a symmetry or central axis of the at least one functional element. At a off-center mounting of the at least one functional element, this can be jammed or braced against a surface of the device, in particular a surface of an optional cover device explained in more detail below or a surface of an optional bearing device explained in more detail below. By jamming or clamping the at least one functional element against a corresponding surface in this manner, the at least one functional element can be secured in the closed position in a comparatively simple manner. Equally, a sealing effect can be achieved in a comparatively simple manner in this way, which prevents sharp waste from escaping undesirably from the device. This can be promoted if the at least one functional element is provided with a sealing section which, in the closed position or in a closed position, is moved relative to the insertion area in such a way that it closes it in a sealing manner. Of course, the sealing section can also be clamped or braced against a corresponding surface in the or a closed position, which increases the sealing effect. A corresponding sealing section can in particular, z. B. in contrast to an operating section provided with an ergonomic geometry and/or with an, in particular three-dimensional, surface structuring, non-contoured section of the at least one functional element.

The mounting of the at least one functional element, which is rotatable about the axis of rotation, enables a rotation of the at least one functional element in a specific angular range in all of the embodiments. The angular range can, for. B. less than 360 °, equal to 360 ° or greater than 360 °. The transfer of the at least one functional element from a position in which a pencil to be sharpened can be inserted into the insertion area into a position (if present) in which a pencil to be sharpened cannot be inserted into the insertion area, or vice versa, typically requires a rotation of the at least one functional element by a certain angle.

An exemplary configuration of the functional device - this applies in particular to an embodiment of the functional device as a locking device - can provide that the transfer of the at least one functional element from a position in which it is possible to insert a pencil to be sharpened into the insertion area into a position ( if present), in which it is not possible to insert a pencil to be sharpened into the insertion area, or vice versa, twisting of the at least one functional element by an angle, e.g. 120°, 90°, 60° or 45° or an integer multiple of an angle of 120°, 90°, 60° or 45°; the at least one functional element can therefore z. B. starting from a position in which it is possible to insert a pencil to be sharpened into the insertion area, correlating first alignment or rotational position by turning through 90° or an integer multiple of an angle of 90° into a position in which it is not possible to insert a pencil to be sharpened into the insertion area, correlating second orientation or rotational position, or vice versa.

In principle, the transfer of the at least one functional element from a position in which a pencil to be sharpened can be inserted into the insertion area (open position) to a position in which a pencil to be sharpened cannot be inserted into the insertion area (closed position) , or vice versa, a rotary movement of the at least one functional element in a first direction of rotation, d. H. e.g. B. clockwise, and a transfer (reverse transfer) of the at least one functional element from the closed position to the open position, a rotary movement of the at least one functional element in a second direction of rotation opposite to the first direction of rotation, d. H. e.g. B. counterclockwise may require. Alternatively or additionally, however, it is also conceivable for the at least one functional element to be transferred from a position in which a pencil to be sharpened can be inserted into the insertion area into a position in which a pencil to be sharpened can not be inserted into the insertion area , a rotary movement of the at least one functional element in a first direction of rotation and the transfer (reverse transfer) of the at least one functional element from the position in which it is not possible to insert a pencil to be sharpened into the insertion area into a position in which a pencil to be sharpened can be inserted is possible in the insertion area, can also require a rotary movement of the at least one functional element in the first direction of rotation.

The rotating or twisting of the at least one functional element for transferring it between respective positions is typically carried out by a direct or indirect actuation by a user. In this case, the user typically sets the at least one functional element manually into a rotational movement, as a result of which it is transferred to the respective positions. Nevertheless, in principle, a z. B. implemented by spring force or motor, drive device conceivable, via which the at least one functional element can be set into a corresponding rotational movement, whereby this is transferred into the respective positions.

The axis of rotation of the at least one functional element is arranged or aligned at an angle, in particular at right angles, relative to the sharpener channel axis. If the axis of rotation of the at least one functional element is arranged or aligned at right angles relative to the axis of the spitzer channel, the axis of rotation of the at least one functional element can be referred to or considered as the horizontal axis and the axis of the spitzer channel can be referred to or considered as the vertical axis. The angular arrangement or orientation of the axis of rotation of the at least one functional element relative to the sharpener channel axis and in particular also the resulting arrangement or orientation of the at least one functional element relative to the sharpener device, i. H. in particular the sharpener channel, enables an improved functional and structural configuration of the device, which is expressed in particular in a reliably effective closure of the insertion area with a compact design and practicable operability by a user.

In all of the embodiments, the at least one functional element can have a rotationally symmetrical geometry or basic shape, at least in sections, optionally completely. This includes e.g. B. cylindrical or -shaped geometries or basic shapes, cone-like or - shaped basic shapes, truncated or -shaped geometries or basic shapes. However, other rotationally symmetrical geometries or basic shapes are also conceivable, i. H. in particular also rotationally symmetrical geometries or basic shapes that are not further defined geometrically.

The at least one functional element can have a base section. The basic section can have a rotationally symmetrical geometry or basic shape. This includes e.g. B. cylindrical or -shaped geometries or basic shapes, cone-like or -shaped basic shapes, truncated or - shaped geometries or basic shapes. In this context, too, other rotationally symmetrical geometries or basic shapes, i. H. in particular, rotationally symmetrical geometries or basic shapes that are not further defined geometrically are also conceivable.

Regardless of its geometry or basic shape, the base section of the at least one functional element can have at least one opening that defines an insertion section for inserting a pencil to be sharpened. The geometric-constructive design of the at least one functional element can therefore have a basic section with a z. B. bore-like or -shaped or channel-like or -shaped opening which - at least in the position in which an insertion of a pencil to be sharpened into the insertion area is possible - defines an insertion section for the insertion of a pencil to be sharpened. The cross-sectional geometry of the opening of the base section of the at least one functional element is therefore typically adapted to the cross-sectional geometry of a pin or pin section to be inserted. The symmetry or central axis of the opening of the base section of the at least one functional element is typically angled, i. H. in particular arranged or aligned at right angles to the axis of rotation of the at least one functional element. The insertion section defined by the opening of the base section of the at least one functional element, in the position in which it is possible to insert a pencil to be sharpened into the insertion area, opens into a position typically in the insertion section of the sharpener channel; in particular such that a continuous insertion channel for inserting a pencil to be sharpened or shaped into the sharpener channel is defined. In any case, the insertion section of the at least one functional element is aligned in the position in which it is possible to insert a pencil to be sharpened into the insertion area, therefore typically, in particular axially, with the insertion area and thus forms, in particular axially with respect to the sharpener channel axis, an extension or extension of the Spitzer canal, which a correctly aligned, i. H. in particular, a centered insertion of a pin or pin section is favored.

If the base section of the at least one functional element has a plurality of openings, in particular bore-like or -shaped or channel-like or -shaped, each defining an insertion section for inserting a pencil to be sharpened, the respective insertion sections of the at least one functional element are aligned in any case in the respective position in which a insertion of a pencil to be sharpened into the insertion area is possible, typically, in particular axially, with the insertion area and thus form, in particular axially with respect to the axis of the sharpener channel, an expansion or extension of the sharpener channel, which enables a correctly aligned, i.e. in particular a centered, insertion of a pencil or .Pin section favored. In this embodiment, each insertion section can be provided with appropriate dimensions, ie, in particular, appropriate diameters, for inserting a pin to be sharpened of a specific configuration, ie, in particular, with a specific diameter, so that through appropriate aligned Aus direction of the insertion sections relative to the insertion area, a correctly aligned, ie in particular a centered, insertion of a pin or pin section can be implemented in a simple manner for different pin configurations.

The base section of the at least one functional element can be provided with a surface structure, i. H. in particular a particularly smooth surface, in order to ensure the best possible sealing between the base section and the insertion area. The same applies to the embodiment of the device, explained further below, with a holding device; Here, the base section of the at least one functional element in the area of its free end facing the insertion area in the or a position in which a pencil to be sharpened can be inserted into the insertion area on the sharpener channel side can be provided with a surface structure, d. H. in particular a particularly smooth surface, in order to achieve the best possible sealing between the base section and the mounting device, d. H. in particular the support element to ensure.

The base section of the at least one functional element can have a single, in particular channel-like or channel-shaped, first opening defining a first insertion section. As indicated above, however, embodiments of the at least one functional element are also conceivable, according to which the base section has a plurality of, in particular channel-like or channel-shaped, openings each defining an insertion section. The at least one functional element can therefore have a base section with a first opening, in particular channel-like or shaped, defining a first insertion section and at least one further opening, in particular channel-like or shaped, defining a further insertion section. A corresponding first opening on the functional element side typically differs from the at least one further opening on the functional element side by at least one geometric-constructive parameter. A corresponding geometric-constructive parameter can in particular be the diameter of the respective openings. The first opening can thus be used for inserting pins of first geometric-constructive dimensions, i. H. in particular a first diameter, and the at least one further opening for inserting pins of further geometric-constructive dimensions, d. H. in particular a further diameter. The respective openings are typically arranged or formed on different sections or areas and thus positions of the at least one functional element. For a functional element configured in a rotationally symmetrical manner, the respective openings can be arranged or formed at different angular positions of the functional element. In this context z. B. an offset by an angle of 120 °, 90 °, 60 ° or 45 ° arrangement or formation of corresponding openings conceivable.

The configuration of the at least one functional element with a plurality of openings typically also means that the at least one functional element can be rotated about the axis of rotation into a first position in which a pencil to be sharpened can be inserted into the insertion area via the first opening, and into at least one additional position Position in which it is possible to insert a pencil to be sharpened into the insertion area via the at least one further opening. Of course, the at least one functional element can also be transferred in this configuration into a position in which it is not possible to insert a pencil to be sharpened into the insertion area.

In all of the embodiments, the device can comprise a bearing device that supports the at least one functional element. A corresponding bearing device typically includes a base body which forms at least one bearing seat for bearing a section of the at least one functional element. A corresponding body can therefore z. B. a bearing seat for storing at least one corresponding base section of the at least one functional element and/or at least one bearing seat for storing at least one bearing section assigned to the base section of the at least one functional element. Corresponding bearing seats can, for. B. be formed by recesses, openings, depressions, wall structures or the like in a corresponding base body. Corresponding bearing seats can also be referred to or considered as counter-bearing sections, which interact with bearing sections of the at least one functional element to form a rotatable bearing of the at least one functional element.

A corresponding bearing device can be arranged or formed, at least in sections, directly or indirectly on or in a corresponding housing device of the device. In particular, a corresponding storage device in the region of a (downward) open end of a corresponding Housing means can be arranged or formed on or in the housing means. An arrangement or design directly or indirectly on a corresponding cover element is also conceivable.

In order to mount the at least one functional element, it can have at least one, in particular pin-like or -shaped or peg-like or -shaped, bearing section for the rotatable mounting of the at least one functional element about the axis of rotation. The at least one storage section, d. H. in particular a bearing section axis, such as. B. a symmetry or central axis of the at least one bearing section, typically defines the axis of rotation of the at least one functional element. With regard to a conceivable, as mentioned, rotationally symmetrical geometry or basic shape of the at least one functional element or the basic section of the at least one functional element, it is conceivable that respective bearing sections can be arranged or aligned centrally or eccentrically.

Embodiments of the at least one functional element with a plurality of bearing sections are possible, with a first bearing section being arranged or formed in the region of a first free end of at least one functional element and a second bearing section being arranged in the region of a second free end of the at least one functional element opposite the first free end or trained. Corresponding bearing sections of the at least one functional element can in principle be mounted directly or indirectly on or in a counter-bearing section arranged or formed on the housing body or the cover element.

Typically, the at least one functional element has at least two, in particular pin-like or -shaped or peg-like or -shaped bearing sections. The arrangement or alignment of the bearing sections is typically selected such that their respective bearing section axes lie on a common straight line. The bearing sections are typically arranged or formed on the base section. Concretely, a first bearing section can be arranged or formed on a first side of the base section; in the case of a base section having a cylindrical or hollow-cylindrical geometry or basic shape, the first bearing section can therefore protrude radially from a first circumferential position of the outer lateral surface of the base section. A second bearing portion may be arranged or formed on a second side of the base portion opposite the first side; in the case of a base section having a hollow-cylindrical geometry, the second bearing section can thus protrude radially from a second circumferential position of the outer lateral surface of the base section lying opposite the first circumferential position.

The device can be equipped with a stop device which comprises at least one stop and/or counter-stop element which, due to its arrangement and/or alignment, defines a certain limit rotational position of the at least one functional element.

For example, at least one stop element can be arranged or formed on the at least one bearing section or--for an embodiment with at least two bearing sections--on at least one bearing section, which, due to its arrangement and orientation, defines a specific limit rotational position of the at least one functional element. Typically, at least two stop elements are arranged or formed on the bearing section, with a first stop element defining a first limit rotational position of the at least one functional element due to its arrangement and orientation, and a second stop element defining a second limit rotational position of the at least one functional element due to its arrangement and orientation. The first limit rotational position of the at least one functional element can correlate with the or a position in which it is possible to insert a pencil to be sharpened into the insertion area on the sharpener channel of the at least one functional element; the second limit rotational position of the at least one functional element can correlate with the closed position of the at least one functional element , or the other way around.

The or a respective stop element can - in corresponding limit rotational positions of at least one functional element - z. B. interact with surfaces arranged or formed on a housing body of a housing device of the device or a cover element of a cover device of the device and forming a counter-stop element. The stop element can thus be moved in a corresponding limit rotational position against a corresponding counter-stop element, which prevents further rotation of the at least one functional element, in particular beyond the respective counter-stop element.

In principle, however, embodiments of the at least one functional element without bearing sections are also conceivable.

As mentioned, the device may comprise housing means. The housing setup may have a housing body which is open on one side and defines a housing space. The housing space typically defines a holding volume for holding shavings such as shavings. B. material removed from a pin as part of a sharpening or molding process.

The device can also include a cover device that can be assigned or is assigned to the housing device. The cover device can have at least one cover element that can be arranged or is arranged on the housing body of the housing device, in particular detachably (without damage or destruction) for closing the housing body of the housing device.

In all of the embodiments, the device can comprise at least one holding device for holding the sharpener device. The holding device can have at least one holding element, in particular a shoulder-like or profile-like or profile-shaped holding element for holding the sharpener device, in particular in a form-fitting and/or non-positive and/or material-locking manner, i. H. in particular a section of the sharpening device that has the insertion area. The mounting device or the at least one mounting element can, for example, be attached to a mounting device for mounting the at least one functional element, i. H. in particular on a base body of the storage device, or on the cover device, d. H. be arranged or formed in particular on the cover element. The sharpener can thus z. B. can be held or held on a corresponding base body of the storage device or on a corresponding cover element.

A corresponding bearing section of the at least one functional element can, as mentioned, be mounted directly or indirectly on or in a counter-bearing section arranged or formed on the housing body or the cover element. A corresponding counter-bearing section, which may also be designated or considered as a bearing seat, can e.g. B. as a rotary bearing mount, which allows a rotatable mounting of the bearing portion about the axis of rotation. The same applies to an embodiment of the at least one functional element with at least two bearing sections, in which at least two corresponding counter-bearing sections can be arranged or formed on the housing body or the cover element.

In all of the embodiments, the device can have a clamping or tensioning device which is used to clamp or tension the at least one functional element in the position or position in which it is not possible to insert a pencil to be sharpened into the insertion area, and/or for clamping or tensioning at least a closing section which can be assigned or is assigned to the insertion area and in which or a position in which it is not possible to insert a pencil to be sharpened into the insertion area. The at least one functional element or one closing section of the at least one functional element can therefore be clamped or braced via a corresponding clamping or clamping device in the position or a position in which it is not possible to insert a pin to be sharpened into the insertion area, so that, in particular on the part of the user, a certain amount of force or moment is required in order to convert the at least one functional element into or into a position in which it is possible to insert a pencil to be sharpened into the insertion area.

A corresponding clamping or clamping device can be set up in particular, any such. B. gap-like or -shaped to close spaces between the insertion area and the at least one functional element, so that the at least one functional element, in particular clamping or clamping force applied, allows a tight closure of the insertion area. This can e.g. by at least partially engaging the at least one functional element or a closing portion of the at least one functional element in the or an opening defining the insertion area and/or by matching the dimensions of the insertion area or the walls surrounding it and the at least one functional element and/or by positioning the at least one functional element as precisely as possible relative to the insertion area.

It follows from the above statements that the at least one functional element can comprise at least one closing section. The at least one closing section can be arranged or formed on the or a base section of the at least one functional element. In particular, the at least one closing section can be arranged or formed in the manner of a tab or in the shape of a tab on the base section of the at least one functional element; consequently, the at least one closing section z. B. in the form of a tab, tongue, or the like, be arranged or formed elastically resilient on the base portion of the at least one functional element. A corresponding clamping or tensioning device can therefore be secured by an elastically resilient or elastically sprung mounting of a corresponding closing section on the base Section of the at least one functional element can be realized. Examples of a concrete implementation of a correspondingly elastically resilient or elastically sprung mounting are described below in connection with a bearing receptacle formed from an elastic material or an elastic material structure for receiving at least one bearing section of the at least one functional element or one made from an elastic material or an elastic material structure formed bearing section of the at least one functional element or an elastic element acting on the functional element.

A corresponding closing section can have at least one, e.g. B. by an elevation relative to other areas of the closing portion formed, comprise closing part, which engages at least partially in the insertion area in the position in which it is not possible to insert a pencil to be sharpened into the insertion area.

The at least one functional element can, as indicated, be mounted elastically, in particular relative to the or a housing device. The elastic storage can, for. B. by formed from an elastic material or an elastic material structure bearing receptacle for receiving at least one bearing portion of the at least one functional element. Alternatively or additionally, at least one bearing section of the at least one functional element can be formed from an elastic material or an elastic material structure, whereby an elastic bearing of the at least one functional element can also be implemented. A corresponding elastic material can, for. B. a natural or synthetic elastomeric material; in particular, thermoplastic elastomer materials come into consideration. A corresponding elastic material structure can, for. B. by appropriate geometric-constructive measures such. B. targeted, z. B. slot-like or -shaped, recesses or weakenings can be realized in the at least one bearing section.

It is also conceivable that an elastic mounting of the at least one functional element via an elastic element, such as. B. a spring element, in particular a compression spring element is realized. As follows, a corresponding elastic element - the same applies in principle to bearing mounts formed from an elastic material or an elastic material structure - can be set up, on the at least one functional element a force which moves the at least one functional element into the position in which insertion of a pencil to be sharpened into the insertion area is not possible.

A corresponding elastic element which z. B. can be arranged or formed in the area of a cover element of a cover device of the device, an engagement structure coupled in a rotationally fixed manner to the at least one functional element can be assigned, into which the elastic element can engage with a free end. A corresponding intervention structure can e.g. B. be realized by alternately arranged or formed elevations and / or depressions. Corresponding elevations and/or depressions can be arranged or aligned in such a way that the elastic element interacts with them when the at least one functional element is transferred into a specific position. An expedient embodiment provides that the elastic element, in particular with its free end, engages in a recess when the at least one functional element is transferred to the position in which it is not possible to insert a pencil to be sharpened into the insertion area. In this way, the at least one functional element can also be secured in this position, which can only be achieved by the force required to move the free end of the elastic element out of the depression. B. whose spring constant - can be overcome. In a similar way, alternatively or additionally, the at least one functional element can be secured in the position in which it is possible to insert a pencil to be sharpened into the insertion area.

A corresponding engagement structure can be part of a z. B. cross-like or shaped, be control section, which is rotatably coupled to the at least one functional element. A corresponding control section can form a pin-like or -shaped or spigot-like or -shaped bearing section for the rotatable mounting of the at least one functional element about the axis of rotation or can be arranged or formed on or in such a bearing.

By elastically mounting the at least one functional element, a corresponding clamping or tensioning device can also be implemented in all of the variants described, since the at least one functional element, due to its positioning, is basically transferred to the position in which it is not possible to insert a pencil that is to be sharpened into the insertion area. so that a transfer of the at least one functional element into a position in which an insertion of a pin to be sharpened into the insertion be is richly possible, an elastic deformation of the respective bearing mounts or bearing sections, in particular in a direction parallel to the axis of the sharpening channel, or an elastic deformation of the elastic element.

Finally, it is alternatively or additionally possible for a corresponding clamping or tensioning device to be implemented in that at least one bearing section of the at least one functional element has an ellipsoidal or elliptical basic shape, i. H. generally has a rounded or oval basic shape deviating from a circle. In this way, rotational movements of the at least one functional element about an axis of rotation defined by the at least one bearing section can, due to the rounded basic shape of the at least one bearing section, result in the at least one functional element becoming jammed or clamped in the position in which a pencil to be sharpened can be inserted in the insertion area is not possible. In this embodiment, a flexible body, such as. B. a cuff may be present, which (r) presses the at least one functional element against the insertion area.

In all of the embodiments, the device can also comprise a reset device assigned to the functional device, in particular to the at least one functional element, which is set up to reset the at least one functional element into a reset position. A corresponding restoring device can be set up in particular for restoring the functional element that has been moved into a specific rotational position that is not equal to a restoring position, into a defined restoring position. A corresponding reset position can be, for example, a position of the at least one functional element in which it is not possible to insert a pencil to be sharpened into the insertion area. Alternatively, a corresponding reset position could be a position of the at least one functional element in which it is possible to insert a pencil to be sharpened into the insertion area.

A corresponding restoring device can comprise at least one restoring element designed to generate a restoring force acting on the at least one functional element, moving the at least one functional element into the restoring position or holding it there. A corresponding restoring element can, in particular, on the one hand or at one end on the at least one functional element and on the other hand or at the other end on a non-rotatably mounted section of the device, such as e.g. B. on a cover device or on a storage device. Appropriate mounting of the restoring element causes a corresponding restoring force to build up when the at least one functional element is rotated, typically as a result of a certain deformation of the restoring element. A corresponding reset element can, for. B. be formed as a spring element or include such.

In all of the embodiments, the device can also comprise a locking device that can be assigned or is assigned to the functional device, in particular to the at least one functional element. The locking device is for locking the at least one functional element in at least one locking position, i. H. e.g. B. in at least one position in which insertion of a pencil to be sharpened into the insertion area is possible and/or in at least one position in which insertion of a pencil to be sharpened into the insertion area is not possible and/or in at least respective positions intermediate position, furnished. By locking the at least one functional element in the respective locking positions, d. H. particularly in the position in which insertion of a pencil to be sharpened into the insertion area is possible or a position in which insertion of a pencil to be sharpened into the insertion area is not possible, e.g. B. it can be ensured that the at least one functional element does not move in an undesired manner from the position in which a pencil to be sharpened can be inserted into the insertion area during a sharpening or shaping process of a pencil to be sharpened, or that the at least one functional element moves is not undesirably moved from the position in which insertion of a pencil to be sharpened into the insertion area is not possible, which may result in an undesirable escape of sharpening waste, such as e.g. B. from a pin as part of a sharpening or molding process material could lead.

The locking device can have at least one locking element, which is set up to generate a locking force acting on the at least one functional element, locking the at least one functional element in a respective locking position and/or for generating a locking force to be overcome in order to transfer the at least one functional element from the respective locking position . A corresponding locking element can, for. B. as a form-fitting element, ie specifically z. B. as a locking or snap element, be formed or at least include such a form-fitting with a z. B. arranged or formed on a housing body of a housing device of the device or a cover element of a cover device of the device, a counter form-fitting element forming surfaces interacts. A corresponding locking element can alternatively or additionally as a magnetic element, ie specifically z. B. as a permanent magnet element, be formed or at least include one that is magnetically connected to a z. B. interacts with surfaces arranged or formed on a housing body of a housing device of the device or a cover element of a cover device of the device and forming a counter-magnetic element.

A corresponding locking element can, for. B. be mounted in at least one degree of freedom along a movement axis or about a movement axis movable, which in the locked position, z. B. form-fitting, acts on the at least one functional element, so that this can not be rotated without releasing the locked position. Specifically, a corresponding locking element z. B. be a along a translation axis movably mounted slide element which in the locked position, z. B. form-fitting, acts on the at least one functional element, so that this can not be rotated without releasing the locked position.

A corresponding locking element can be assigned at least one restoring element configured to generate a restoring force that acts on the at least one locking element, moves the at least one locking element into the locking position or holds it there. A corresponding reset element can, for. B. as a spring element, such as. B. a compression spring, be formed or include such.

In all of the embodiments, the device can also include a rotary mechanism for generating a rotary movement that converts the at least one functional element into a corresponding open position and/or into a corresponding closed position. A corresponding rotary mechanism can consist of an actuator element that is mounted so that it can move along a translation axis and has an actuator active section, particularly in the region of a free end facing the at least one functional element; a functional element active portion which interacts with the actuator active portion and is coupled in a rotationally fixed manner to the at least one functional element active portion which is mounted here in addition to the rotatable mounting so as to be movable about the axis of rotation along the translation axis; a control path for the functional element active portion defining, rotatably mounted on a non-rotatable portion of the device, d. H. in particular on a cover device and/or a bearing device supporting the at least one functional element, arranged or formed control element; and a spring element arranged to act in the direction of the translation axis, e.g. B. a compression spring include. The translation axis is typically arranged or aligned at an angle or at right angles to the axis of the spitzer channel; the translation axis typically corresponds to the axis of rotation about which the at least one functional element is rotatably mounted.

The aforementioned components of the rotary mechanism work together in such a way that when the actuator element is moved, typically by a user, along the translation axis counter to the direction of action of the spring element, the at least one functional element together with the functional element effective section coupled to it is also moved along the translation axis, whereby the Functional element active section is moved relative to the positionally fixed control. When the at least one functional element is moved back by the spring element, the control element acts on the functional element active section, so that this is moved along the control path, resulting in a rotational movement of the at least one functional element. The rotational movement is typically defined by the geometric-constructive design of the control element in such a way that the at least one functional element moves from a position in which a pencil to be sharpened can be inserted into the insertion area to a position in which a pencil to be sharpened can be inserted into the insertion area is not possible, or vice versa, and/or defined in such a way that the at least one functional element moves from a first position, in which it is possible to insert a pencil to be sharpened into the insertion area, into a further position, in which it is possible to insert a pencil to be sharpened is possible in the insertion area, or vice versa.

The aforementioned functional principle of the rotary mechanism is typically based on the principle of the movement of a refill of a ballpoint pen. The rotary mechanism can therefore be referred to or considered as a ballpoint pen mechanism.

A corresponding rotary mechanism can be particularly expedient in connection with a cone-like or -shaped or truncated cone-like or -shaped functional element, as a sealing effect sealing the insertion area can be achieved by moving the functional element along the translation axis.

A corresponding bearing device, which supports the at least one functional element, can be provided here with a radio with the cone-like or -shaped or truncated-cone-like or -shaped radio tion element cooperating, optionally corresponding, conical (truncated) surface can be provided along which or against which the at least one functional element can be moved during a movement brought about by the spring element along the translation axis.

The at least one functional element can be at least one, at least in sections, if appropriate completely, with an ergonomic geometry and/or at least in sections, if necessary completely, with a, in particular three-dimensional, surface structure, such as e.g. B. a corrugation, provided actuating portion. A corresponding actuation section is typically arranged or formed in the area of the base section of the at least one functional element. Appropriate surface structuring can improve the operability of the at least one functional element, since the surface of the at least one functional element to be touched by a user to rotate the at least one functional element can be specifically provided with increased friction.

A corresponding actuation section can be formed in one piece with the at least one functional element. Consequently, a corresponding actuation section can be a one-piece and thus an integral part of the at least one functional element. This can e.g. B. be realized in which an outer surface, such as. B. a lateral surface, the at least one functional element is provided with a corresponding operating section forming at least partially, optionally completely, with an ergonomic geometry and / or with a, in particular three-dimensional, surface structuring.

However, a corresponding actuation section can also be formed separately from the at least one functional element. Consequently, a corresponding actuation section can be a component of a component that is separate from the at least one functional element. Of course, several corresponding actuating sections can be provided on several corresponding components. A corresponding component can, for. B. have a cylindrical geometry or basic shape and be provided in the area of its lateral surface with an ergonomic geometry and / or with a, in particular three-dimensional, surface structuring.

A corresponding component can typically be coupled or is coupled to the at least one functional element. For this purpose, both on the part of a corresponding component and on the part of the at least one functional element, coupling sections, i. H. e.g. B. force and / or form-fitting sections, be present, via their interaction results in a coupling of the component with the at least one functional element. Movements of the component can be converted into rotary movements of the at least one functional element about the axis of rotation via a corresponding coupling. Corresponding movements of a corresponding component can in particular be rotational movements, so that rotational movements of the component can be converted into, in particular rectified, rotational movements of the at least one functional element about the axis of rotation. A corresponding rotatably mounted component can be mounted such that it can rotate about the same axis of rotation as the at least one functional element. However, it is also conceivable that a corresponding component is mounted so as to be rotatable about a different axis of rotation than the at least one functional element. A corresponding component can therefore z. B. be rotatably mounted to the axis of rotation of at least one functional element arranged parallel axis of rotation.

In principle, a corresponding component can be directly or indirectly, i. H. with the interposition of at least one further component or a component group with which at least one functional element can be or can be coupled. A corresponding further component or a corresponding further component group can be, for. B. be a gear element or a gear device, so that movements of a corresponding component with a positive or negative transmission ratio can be transferred to the at least one functional element. Corresponding gear elements can, for. B. be formed by gears or include such. A specific configuration of a transmission device formed by corresponding transmission elements can, for. B. include a non-rotatably coupled to a corresponding component first gear and cooperating with this, non-rotatably coupled to the at least one functional element additional gear. Specifically, such z. B. can be achieved that a rotational movement of a corresponding component by a first angular range in rotational movements of the at least one functional element in a different from the first angular range second angular range result. For example, a rotary movement of a corresponding component z. B. by 15 ° in a rotational movement of the at least one functional element z. B. by 30° or by 7.5°. Consequently, in principle positive or negative transmission ratios are conceivable.

In all embodiments, the device can therefore be one of the functional devices, in particular Special the at least one functional element, include associated transmission device. A corresponding transmission device can be set up to convert movements, ie in particular rotary movements, of a component coupled to the at least one functional element into positive or negative rotary movements of the at least one functional element. If the corresponding transmission elements are gears, a corresponding transmission device can be used, e.g. B. be designed as a spur gear or gear transmission.

the 1 - 4 12 show a schematic representation of a device 1 for sharpening or shaping a pencil (not shown) according to a first exemplary embodiment. The show 1 and 3 each external views of the device 1 and the 2 and 4 sectional views of the device 1.

The device 1 can also be referred to or considered as a pencil sharpener or pencil shaper. In principle, any type of pen or pencil lead can be sharpened or shaped with the device 1, so that writing, drawing or cosmetic pencils are only referred to as examples.

The device 1 comprises a sharpening device 2 for sharpening or shaping at least one pencil to be sharpened by means of the device 1 . The sharpening device 2 has a sharpener channel 4 that is accessible via an in particular hollow-cylindrical insertion area 3 for the insertion of a pencil to be sharpened. The cross-sectional geometry of the sharpener channel 4 is typically adapted to the cross-sectional geometry of a pencil or pencil section to be inserted. The Spitzerka nal 4 defines a spitzer channel axis A1. In the in the 1 - 4 In the exemplary embodiment shown, the sharpener channel 4 has, for example, a conical or truncated cone-shaped geometry or basic shape. The sharpener channel axis A1 is defined by the symmetry or central axis of the sharpener channel 4 in the shape of a cone or a truncated cone.

The sharpening device 2 has at least one, e.g. B. knife-like or - shaped, pointed element 5, which is used for sharpening or shaping a pin or pin section inserted into the sharpener channel 4 via the insertion region 3, d. H. typically a pen tip.

It can be seen from the figure that the sharpening device 2 has a base body 6 . The sharpener channel 4 is arranged or formed in the base body 6 by a corresponding recess, opening or the like. The pointed element 5 is arranged or formed on or in the base body 6 .

The body 6 can, as in the 2 and 4 shown, have a wedge-like or wedge-shaped geometry or basic shape defined by a planar base surface (not specified) and an inclined surface running obliquely thereto (not specified). The sharpener channel 4 is arranged or formed with the sharpener channel axis A1 extending along the base of the wedge-like or wedge-shaped base body 6 . The sharpening element 5 is arranged or formed on or in the inclined surface of the wedge-like or wedge-shaped base body 6 .

Visible is the sharpener 2, i. H. in particular the base body 6 of the sharpener device 2, at least partially arranged or formed within a housing device 7 of the device 1. The housing device 7 has a housing body 9 that defines a housing space 8 that is open on one side. The sharpener 2, i. H. in particular the base body 6 of the sharpener device 2 is arranged or formed within the housing space 8 defined by the housing body 9 . The housing space 8 typically defines a receiving volume for receiving sharps such as e.g. B. removed from a pin or pin portion in a sharpening process material.

The device 1 also includes a functional device 10. In the exemplary embodiments shown in the figures, the functional device 10 is designed, for example, as a closure device for closing the insertion area 3 on the sharpener channel side, in particular when required. The functional device 10, which can therefore be referred to as a closure device, has a functional element 11 that can be assigned or is assigned to the insertion area 3 on the sharpener channel side and can also be referred to as a closure element. The functional element 11 is rotatably mounted about an axis of rotation A2 arranged or aligned at an angle, ie in particular at right angles, to the sharpener channel axis A1. The axis of rotation A2 of the functional element 11 can in the in the 1 - 4 In the embodiment shown, the sharpener channel axis A1 can be referred to as the vertical axis.

The functional element 11 is rotated about the axis of rotation A2 in at least one in the 3 , 4 shown, which can also be called the open position, in which it is possible to insert a pencil to be sharpened into the insertion area 3 on the sharpener channel side, and in at least one into the 1 , 2 shown further position, which can also be referred to as the closed position, in which it is not possible to insert a pencil to be sharpened into the insertion area 3 on the sharpener channel side. The functional element 11 can thus be transferred into a plurality of positions or rotational positions by rotating about the axis of rotation A2, with at least one rotational position having a first position of the functional element 11, in which it is possible to insert a pencil to be sharpened into the insertion region 3 on the sharpener channel, and at least one rotational position correlates with at least one further position of the functional element 11 in which it is not possible to insert a pencil to be sharpened into the insertion area 3 on the sharpener channel side.

The mounting of the functional element 11, which is rotatable about the axis of rotation A2, enables the functional element 11 to be rotated in a specific angular range. The angular range can, for. B. less than 360 °, equal to 360 ° or greater than 360 °. The transfer of the functional element 11 from an open to a closed position, or vice versa, typically requires the functional element 11 to be rotated by a specific angle.

The exemplary configuration of the functional device 10 according to the exemplary embodiments shown in the figures provides, for example, that the transfer of the functional element 11 from the or a first position into the or a further position, or vice versa, involves rotating the functional element 11 by one 90° angle required; the functional element 11 can therefore z. B. starting from a with in the 3 , 4 shown first position correlating first orientation or rotational position by rotating by 90 ° in one with the in 1 , 2 further position shown cor relative second orientation or rotational position, or vice versa, are transferred.

In the exemplary embodiment shown in the figures, the transfer of the functional element 11 from the first position to the further position, or vice versa, requires a rotational movement of the functional element 11 in a first rotational direction, i. H. e.g. B. clockwise, and a transfer (return) of the functional element 11 from the further position to the first position, a rotational movement of the functional element 11 in a second direction of rotation opposite to the first direction of rotation, d. H. e.g. B. counterclockwise. Alternatively or additionally, however, it is also conceivable that a transfer of the functional element 11 from the first position to the further position involves a rotary movement of the functional element 11 in a first direction of rotation and the transfer (reverse transfer) of the functional element 11 from the further position to the first position as well requires a rotary movement of the functional element 11 in the first direction of rotation.

The rotating or twisting of the functional element 11 in order to transfer it between the respective first and further positions is typically effected by actuation by a user. The user manually causes the functional element 11 to rotate, as a result of which it is transferred into the respective first and further positions. Nevertheless, in principle, a z. B. spring force-implemented or motorized, drive device conceivable, via which the functional element 11 is displaceable in a corresponding rotational movement, whereby this is converted into respective first and further positions.

In particular based on the 2 , 4 The sectional views shown show that the functional element 11 has a basic section 11.1 with a cylindrical or hollow-cylindrical geometry or basic shape. The base section 11.1 has a bore-like or -shaped or channel-like or -shaped opening 11.2 defining an insertion section for inserting a pencil to be sharpened. The cross-sectional geometry of the opening 11.2 is typically adapted to the cross-sectional geometry of a pin or pin section to be inserted. The symmetry or central axis of the opening 11.2 is in the in the 1 - 4 shown embodiment arranged or aligned at right angles to the axis of rotation A2 of the functional element 11. The insertion section defined by the opening 11.2 is aligned, as in 4 As can be seen, at least in the first position of the functional element 11, it is axially connected to the insertion area 3 on the sharpener channel side and thus represents an axial widening or extension of the sharpener channel 4.

To mount the functional element 11, it has two pin-like or -shaped or peg-like or -shaped bearing sections 11.3, 11.4 for the rotatable mounting of the functional element 11 about the axis of rotation A2. The bearing sections 11.3, 11.4 are arranged or formed on the base section 11.1 of the functional element 11. Specifically, a first bearing section 11.3 is arranged or formed on a first side of the base section 11.1 and protrudes radially from a first circumferential position of the outer lateral surface of the base section 11.1. A second bearing section 11.4 is arranged or formed on a second side of the base section 11.1 opposite the first side and protrudes radially from a second circumferential position of the outer lateral surface of the base section 11.1, opposite the first circumferential position.

It can be seen that the bearing section axes, ie in particular the symmetry or central axes, define the bearing sections 11.3, 11.4 in the 1 - 4 shown embodiment, the axis of rotation A2 of the functional element 11. The arrangement or alignment of the bearing sections 11.3, 11.4 is selected so that they lie with their respective bearing section axes on a common straight line.

The figure shows that at least one stop element 11.5, 11.6 can be arranged or formed on each of the bearing sections 11.3, 11.4. The respective stop element 11.5, 11.6 can define a specific limit rotational position of the functional element 11 due to its arrangement and orientation. Typically, at least two stop elements 11.5, 11.6 are arranged or formed on each bearing section 11.3, 11.4, with a respective first stop element 11.5, 11.6 defining a first limit rotational position of the functional element 11 due to its arrangement and orientation, and a respective second stop element 11.5, 11.6 due to its arrangement and Alignment defines a second limit rotational position of the functional element 11. The respective first limit rotational position of the functional element 11 can correlate with the first position of the functional element 11, the respective second limit rotational position of the functional element 11 can correlate with the further position of the functional element 11, or vice versa.

The respective stop elements 11.5, 11.6 can - in corresponding limit rotational positions of the functional element 11 - z. B. interact with surfaces 13.1, 13.2 which are arranged or formed on a cover element 12 of a cover device 13 of the device 1 and form a counter-stop element. The stop elements 11.5, 11.6 can therefore in a corresponding limit rotational position can be moved against a corresponding counter-stop element, which prevents further rotation of the functional element 11, in particular beyond the respective counter-stop element.

The surfaces 13.1, 13.2 can be arranged or formed on a holding element 14, arranged or formed on the cover element 12, of a holding device 15 for holding the sharpener device 2.

The device 1 can therefore comprise a cover device 13 that can be assigned or is assigned to the housing device 7 and has a cover element 12 that is arranged on the housing body 9 and is in particular detachable (without damage or destruction) for closing the housing body 9 .

The already mentioned mounting device 15 for mounting the sharpening device 2 can have a mounting element 14, in particular a shoulder-like or profile-like or profile-shaped mounting element 14 for, in particular, positive and/or non-positive and/or cohesive mounting of the sharpening device 2. Since the support device 15 and the support member 14 in the in the 1 - 4 shown embodiment is arranged or formed on the cover element 12, the sharpening device 2 is in the in the 1 - 4 embodiment shown on the cover element 12 can be held or held.

The bearing sections 11.3, 11.4 of the functional element 11 are in the in the 1 - 4 shown embodiment is mounted on respective counter-bearing sections arranged or formed on the cover element 12 or the holding element 14 . The counter bearing sections can z. B. as a rotary bearing mount, which allows a rotatable mounting of the respective bearing section 11.3, 11.4 about the axis of rotation A2.

The base section 11.1 of the functional element 11 can be provided with a surface structuring, i. H. in particular a particularly smooth surface, in order to ensure the best possible sealing between the base section 11.1 of the functional element 11 and the mounting element 14.

The functional element 11 can, as shown in the 1 , 3 as can be seen, at least one at least partially, optionally completely, with an ergonomic geometry and / or at least partially, optionally completely, with a, in particular three-dimensional, surface structure 16, such as. B. a corrugation, provided actuating portion 17 have. The operating section is in the in the 1 - 4 shown embodiment in the area of the base portion 11.1 of the functional element 11, ie in particular in the area of the lateral surface of the base portion 11.1., Arranged or formed.

Based on the 5 , 6 The exemplary embodiment shown shows that the device 1 can include a resetting device 20 assigned to the functional element 11, which is set up for resetting the functional element 11 into a reset position. The restoring device 20 is basically set up for restoring the functional element 11, which has been moved into a specific rotational position that is not equal to a restoring position, into a defined restoring position. In the in the 5 , 6 The embodiment shown is the reset position, for example, a closed position of the functional element 11. Equally, the reset position could be a corresponding open position of the functional element 11.

The resetting device 20 includes in the in the 5 , 6 The exemplary embodiment shown shows, for example, two restoring elements 21 each designed to generate a restoring force that acts on the functional element 11, moves the functional element 11 into the restoring position or holds it in this restoring force. The restoring elements 21 are in the 5 , 6 shown embodiment on the one hand or at one end on the functional element 11 and on the other hand or at the other end on a non-rotatably mounted portion of the device 1, such as. B. is mounted on the cover element 12 of the cover device 13 . This mounting of the restoring elements 21 causes a corresponding restoring force to build up when the functional element 11 is rotated, resulting from a certain deformation of the restoring elements 21 . The restoring elements 21 are in the in the 5 , 6 shown embodiment each formed as a spring element.

In the in the 5 , 6 The exemplary embodiment shown also shows a bearing device 22 supporting the functional element 11 . The storage device 22 includes a base body 22.1, which, for example, a first bearing seat 22.2 for storing the functional element 11 and further bearing seats 22.3 for storing respective bearing sections 11.3, 11.4 of the functional element 11 are defined. As can be seen, the bearing seats 22.2, 22.3 z. B. be formed by recesses, openings, depressions, wall structures or the like in the base body 22.1. The bearing seats 22.2, 22.3 can also be referred to as counter bearing sections, which interact with bearing sections 11.3, 11.4 of the functional element 11 to form a rotatably mounted arrangement of the functional element 11 in the bearing device 22.

The planes are like in particular 7 shows in which in the 7 - 9 shown embodiment example as, in particular groove-like or - shaped recess in the bearing section 11.4.

the 10 - 12 show a schematic representation of a device 1 according to a further embodiment. The show 10 , 11 the device 1 in a perspective view and 12 the device 1 in an exploded view.

Based on the 10 - 12 shown embodiment, it can be seen that corresponding actuating sections 17 can be formed separately from the functional element 11. Consequently, corresponding actuating sections 17 can be components of a functional element 11 be separate components 24. These components 24 have in the in the 10 - 12 The exemplary embodiment shown has, for example, a cylindrical geometry or basic shape and is provided with an ergonomic geometry and/or with a, in particular three-dimensional, surface structure 17 in the area of its lateral surfaces.

The components 24 can be coupled or are coupled to the functional element 11 . For this purpose, both the components 24 and the functional element 11 have coupling sections 11 . 7 , 24 . Movements of the components 24 can be converted into rotary movements of the functional element 11 via a corresponding coupling. With corresponding movements of the components 24 is in the in 10 - 12 The exemplary embodiment shown is, for example, rotational movements, so that rotational movements of the components 24 can be converted into, in particular rectified, rotational movements of the functional element 11 . The components 24 are in the in the 10 - 12 shown exemplary embodiment about the same axis of rotation A2 as the functional element 11 rotatably mounted. However, it is also conceivable that the components 24 are mounted rotatably about a different axis of rotation than the functional element 11 . The components 24 can thus z. B. to be rotatably mounted to the axis of rotation A2 of the functional element 11 arranged parallel axis of rotation.

Basically, corresponding components 24 directly or indirectly, i. H. with the interposition of at least one further component or a component group, can be or can be coupled to the functional element 11 .

the 13 - 15 show a schematic representation of a device 1 according to a further embodiment. while showing 13 a perspective view of the device 1, 14 an enlarged view of a functional element 11 comprehensive assembly and 15 the device 1 in an exploded view.

Based on the 13 - 15 From the exemplary embodiment shown, it can be seen that a corresponding further component 24 or a corresponding further component group can be a transmission element or a transmission device, so that movements of a corresponding component 24 can be transmitted to the functional element 11 with a positive or negative transmission ratio. Corresponding transmission elements 25, 26 are as shown in the individual view 14 shows in which in the 13 - 15 shown embodiment formed by gears or include such. The in the in the 13 - 15 The specific configuration shown in the exemplary embodiment shown, of a transmission device formed by corresponding transmission elements 25, 26, comprises a first gear wheel coupled in a torque-proof manner to the component 24 and a further gear wheel cooperating therewith and coupled in a torque-proof manner to the functional element 11. Specifically, such z. B. can be achieved that a rotational movement of the component 24 by a first angular range in rotational movements of the functional element 11 in a different from the first angular range second angular range result. For example, a rotational movement of the component 24 z. B. by 15 ° in a rotational movement of the functional element 11 z. B. by 30° or by 7.5°. Consequently, in principle positive or negative transmission ratios are conceivable.

Based on the 13 - 15 From the exemplary embodiment shown, it can therefore be seen that the device 1 can include a transmission device assigned to the functional element 11 . If the corresponding transmission elements 25, 26 are gears, a corresponding transmission device can be designed as a gear transmission.

the 16 - 19 show a schematic representation of a device 1 according to a further embodiment. The show 16 - 18 the device 1 in a partially sectioned view and 19 the device 1 in an exploded view.

Based on the 16 - 19 The exemplary embodiment shown shows that the device 1 can have a functional element 11 with a base section 11.1 with a plurality of channel-like or channel-shaped openings 11.2.1, 11.2.2 each defining an insertion section. Specifically, the functional element 11 in which in the 16 - 19 The exemplary embodiment shown has, by way of example, a base section 11.1 with a channel-like or -shaped first opening 11.2.1 defining a first insertion section and a channel-like or -shaped second opening 11-2.2 defining a second insertion section. The first opening 11.2.1 differs from the second opening 11.2.2 by at least one geometric-constructive parameter. A corresponding geometric-constructive parameter can in particular be the diameter of the respective openings 11.2.1, 11.2.2. The first opening 11.2.1 can therefore be used for inserting pins of first geometric-constructive dimensions, ie in particular a first diameter, and the second opening 11.2.2 for inserting pins of additional ones geometric-constructive dimensions, ie in particular a further diameter, be set up.

The openings 11.2.1, 11.2.2 are in the 16 - 19 shown embodiment arranged or formed on different sections or areas and thus different positions of the functional element 11. Specifically, the openings 11.2.1, 11.2.2 are arranged or formed at different angular positions of the functional element 11, which here has a rotationally symmetrical geometry or basic shape, for example. Specifically, the openings 11.2.1, 11.2.2 are designed, for example, in an arrangement or design offset by an angle of 90°.

The configuration of the functional element 11 with a plurality of openings 11.2.1, 11.2.2 also typically means that the functional element 11 can be rotated about the axis of rotation A2 into a first open position, in which a pencil to be sharpened can be inserted into the insertion area 3 on the sharpener channel via the first opening 11.2.1 is possible, and can be converted into a second open position, in which it is possible to insert a pencil to be sharpened into the insertion area 3 on the sharpener channel side via the second opening 11.2.2. Of course, the functional element 11 can also be transferred in this configuration into a closed position in which it is not possible to insert a pencil to be sharpened into the insertion area 3 on the sharpener channel side.

the 20 - 22 show a schematic representation of a device 1 according to a further embodiment. The show 20 , 21 the device 1 in a sectional view and 22 the device 1 in an exploded view.

Based on the 20 - 22 The exemplary embodiment shown shows that the device 1 can comprise an off-center (eccentric) mounted functional element 11 . Specifically, the functional element 11, which has a rotationally symmetrical geometry or basic shape, is in the 20 - 22 shown embodiment mounted eccentrically with respect to its symmetry or central axis. When the functional element 11 is mounted off-centre, it can be moved into or into a closed position, as in 20 shown, are clamped or braced against a surface of the device 1, in particular a surface of the bearing device 22. By jamming or clamping the functional element 11 against a corresponding surface in this manner, the functional element 11 can be secured in the closed position in a comparatively simple manner. Equally, a sealing effect can be achieved in a comparatively simple manner in this way, which prevents sharp waste from escaping undesirably from the housing device 6 of the device 1 . This can be favored if the functional element 11, as in the 20 - 22 indicated by way of example, is provided with a non-descript sealing section, which in the closed position is moved relative to the insertion area 3 on the sharpener channel side in such a way that it closes it in a sealing manner. Of course, the sealing section can also be clamped or braced against a corresponding surface in the closed position, which increases the sealing effect. A corresponding sealing section can be seen in particular, e.g. B. in contrast to an operating section 17 provided with an ergonomic geometry and/or with an, in particular three-dimensional, surface structure 17, non-contoured section of the functional element 11 (cf. 21 ). In the embodiment according to the 20 - 22 shown restoring elements 21 are optional.

the 23 - 27 show a schematic representation of a device 1 according to a further embodiment. The show 23 - 26 the device 1 in a partially sectioned view and 27 the device 1 in an exploded view.

Based on the 23 - 27 In the exemplary embodiment shown, it can be seen that device 1 has a rotary mechanism 27 for generating a functional element 11 in one of the at least one position in which it is possible to insert a pencil to be sharpened into the insertion area 3 on the sharpener channel, and/or in the at least one position , in which it is not possible to insert a pencil to be sharpened into the insertion area 3 on the sharpener channel side, can comprise transferring rotary movement.

• Ein erster Bestandteil der Drehmechanik 27 ist ein entlang einer quer zu der Spitzerkanalachse A1 und somit koaxial zu der Drehachse A2 des Funktionselements 11 ausgerichteten Translationsachse bewegbar gelagertes Aktorelement 28 mit einem, insbesondere im Bereich eines dem wenigstens einen Funktionselement 11 zugewandten freien Endes, angeordneten oder ausgebildeten Aktorwirkabschnitt 28.1. Der Aktorwirkabschnitt 28.1 kann eine kronenartige bzw. -förmige Geometrie aufweisen.

In the exemplary embodiment shown, the rotary mechanism 27 comprises the components explained in more detail below:

• A first component of rotary mechanism 27 is an actuator element 28, which is movably mounted along a translation axis aligned transversely to the sharpener channel axis A1 and thus coaxially to the axis of rotation A2 of functional element 11, with a free end that is arranged or configured, in particular in the area of a free end facing the at least one functional element 11 Actuator effective section 28.1. The active actuator section 28.1 can have a crown-like or crown-shaped geometry.

A second component of the rotary mechanism 27 is a functional element active section 29 which interacts with the actuator active section 28.1 and is non-rotatably coupled to the functional element 11, which is mounted here in addition to the rotatable mounting so that it can move translationally along the translation axis about the axis of rotation A2. The functional element active section 29 can have a geometry comprising a plurality of ramp-like sections exhibit.

A third component of the rotary mechanism 27 is a control path for the functional element effective section 29 defining a rotationally fixed to a non-rotatably mounted section of the device 1, i. H. in particular on the bearing device 22, arranged or formed control element 30. The control element 30 can also have a plurality of sections running ramp-like geometry.

A fourth component of the rotary mechanism 27 is a spring element 31, e.g. B. in the form of a compression spring.

The aforementioned components of the rotary mechanism 27 act as in the 23 - 26 indicated, together in such a way that a movement of the actuator element 28 along the translation axis, typically brought about by a user, in the opposite direction to the direction of action of the spring element 31 moves the functional element 11 together with the functional element effective section 29 coupled thereto along the translation axis, whereby the functional element effective section 29 is moved relative to the positionally fixed control element 30. When the functional element 11 is moved back, brought about by the spring element 31, the control element 30 acts on the functional element active section 29, so that this is moved along the control path, resulting in a rotational movement of the functional element 11. The rotational movement is defined by the geometric-constructive design of the control element 30 in such a way that the functional element 11 is transferred from an open position to the closed position, or vice versa, and/or defined in such a way that the functional element 11 is moved from a first open position to a further open position , or vice versa.

The aforementioned functional principle of the rotary mechanism 27 is based on the principle of the movement of a refill of a ballpoint pen. The rotary mechanism 27 can therefore be referred to or considered as a ballpoint pen mechanism.

the 28 - 31 show a schematic representation of a device 1 according to a further embodiment. The show 28 - 30 the device 1 in a sectional view and 31 the device 1 in an exploded view.

Based on the 28 - 31 shown embodiment, it can be seen that as in the in the 23 - 27 The rotary mechanism 27 shown in the exemplary embodiment shown can be particularly expedient in connection with a cone-like or -shaped or truncated cone-like or -shaped functional element 11, as by moving the functional element 11 along the translation axis, a sealing effect can be achieved that seals the insertion area 3 on the spitzer channel side (cf. 28 ).

The bearing device 22 supporting the functional element 11 can here be provided with a conical (truncated) surface which interacts with, in particular corresponds to, the conical or -shaped or truncated cone-like or -shaped functional element 11, along which or against which the functional element 11 movement brought about by the spring element 31 along the translation axis.

the 32 - 34 show a schematic representation of a device 1 according to a further embodiment. The show 32 and 33 the device 1 in a sectional view and 34 an enlarged view of the functional element 11 of the device 1 in a perspective view.

Based on the 32 - 34 The exemplary embodiment shown shows a conceivable realization of a clamping or clamping device 32, which is used to clamp or clamp the functional element 11 in the or an in 33 shown position, in which insertion of a pencil to be sharpened into the insertion area 3 is not possible. In particular, a corresponding clamping or clamping device 32 can be set up to clamp or clamp a closing section 11.8 that can be assigned or is assigned to the insertion area 3 in the or a position in which it is not possible to insert a pencil to be sharpened into the insertion area 3. The functional element 11 or a corresponding closing section 11.8 can - as in 33 shown - can therefore be clamped or braced via a corresponding clamping or tensioning device 32 in the or a position in which it is not possible to insert a pencil to be sharpened into the insertion area 3, so that, in particular on the user side, a certain amount of force or Torque effort is required to move the functional element 11 into the or an in 32 position shown ment, in which an insertion of a pencil to be sharpened into the insertion area 3 is possible.

The clamping or clamping device 32 is set up in particular, any such. B. gap-like or -shaped, to close spaces between the insertion area 3 and the functional element 11, so that the functional element 11, in particular clamping or tensioning force applied, a tight closure of the insertion area 3 allows. This can, as in 33 indicated, e.g. B. by at least partially engaging the functional element 11 or the closing section 11.8 in an opening (not labeled) defining the insertion area 3 and/or by matching the dimensions of the insertion area 3 or the walls surrounding it and the functional element as precisely as possible in terms of geometry and construction 11 and/or by positioning the functional element 11 as precisely as possible relative to the insertion area 3 .

Based on 34 it can be seen that a corresponding closing section 11.8 can be arranged or formed on the base section 11.1 of the functional element 11. In particular shows 34 that a corresponding closing section 11.8 - of course, several corresponding closing sections 11.8 could be present, in particular in an arrangement lying opposite one another - be arranged or formed in a tab-like or -shaped manner on the base section 11.1 of the functional element 11; consequently, a corresponding closing section 11.8 z. B. in the form of a tab, tongue, or the like, be arranged or formed in an elastically resilient manner on the base section 11.1 of the functional element 11. The clamping or tensioning device 32 can therefore be realized by an elastically resilient mounting of a corresponding closing section on the base section of the at least one functional element.

the 32 - 34 also show that a corresponding closing section 11.8, e.g. B. by an elevation relative to the other areas of the closing section 11.8 can include closing part 11.9, which in the position in which it is not possible to insert a pencil to be sharpened into the insertion area 3, engages at least in sections in the insertion area 3 (cf. 33 ).

the 35 - 37 show a schematic representation of a device 1 according to a further embodiment. The show 35 and 36 the device 1 in a sectional view and 37 the device 1 in an exploded view.

Based on the 35 - 37 The exemplary embodiment shown shows a further conceivable realization of a clamping or tensioning device 32 via an elastic mounting of the functional element 11 .

The elastic mounting of the functional element 11 is formed here by bearing receptacles 22.5, 22.6 made of an elastic material or an elastic material structure for accommodating respective bearing sections 11.3, 11.4 of the functional element 11. The bearing mounts 22.5, 22.6 are shown as separate insert components; consequently, these could alternatively also be designed in one piece with the bearing device 22 or corresponding bearing seats 22.3.

38 shows a schematic representation of a device 1 according to a further embodiment. while showing 38 an enlarged view of the functional element 11 of the device 1 in a perspective view.

Based on the in 38 The exemplary embodiment shown shows a further conceivable realization of a clamping or tensioning device 32 via an elastic mounting of the functional element 11 .

The functional element 11 is in the in 38 The embodiment shown is therefore elastically mounted, in particular relative to the housing device or devices. The elastic mounting of the functional element 11 is formed by an elastic design of the bearing sections 11.3, 11.4 of the functional element 11 from an elastic material structure. Based on 38 it can be seen that a corresponding elastic material structure z. B. by appropriate geometric-constructive measures such. B. targeted, z. B. slot-like or -shaped, recesses or weakenings in the bearing sections 11.3, 11.4 of the functional element 11 can be realized. Alternatively or additionally, the bearing sections 11.3, 11.4 of the functional element 11 could be formed from an elastic material. A corresponding elastic material can, for. B. be a natural or synthetic elastomeric material. In particular, thermoplastic elastomer materials come into question.

Based on the 35 - 38 It is therefore evident that a corresponding clamping or tensioning device 32 can also be implemented by means of an elastic mounting of the functional element 11, since the functional element 11, due to its mounting, is basically in the position in which it is not possible to insert a pencil to be sharpened into the insertion area 3 , Is transferred, so that a transfer of the functional element 11 in a position in which a Insertion of a pencil to be sharpened into the insertion area 3 is possible, an elastic deformation of the respective bearing receptacles 22.5, 22.6 or bearing sections 11.3, 11.4 in a direction parallel to the sharpener channel axis A1 is required.

the 39 - 41 show a schematic representation of a device 1 according to a further embodiment. The show 39 and 40 the device 1 in a sectional perspective view and 41 the device 1 in a sectional side view.

Based on 39 - 41 a further possibility of an elastic mounting of the functional element 11 and an associated realization of a corresponding clamping or tensioning device 32 can be seen.

In the in the 39 - 41 shown embodiment is an elastic mounting of the functional element 11 via an elastic element 34 - shown purely by way of example in the form of a compression spring element - realized. The elastic element 34 - of course, several corresponding elastic elements 34 could be present, in particular in a symmetrical arrangement with respect to the sharpener channel axis A1 - be set up to exert a force on the functional element 11, which moves the functional element 11 into the position in which insertion of a Pen is not possible in the insertion area, transferred.

The elastic element 34, which in the exemplary embodiments shown in the figures is arranged or formed, for example, in the area of the cover element 12 of the cover device 13 of the device 1, can be assigned an engagement structure 35 that is coupled to the functional element 11 in a rotationally fixed manner, into which the elastic element 34 can engage with a free end. As can be seen, the engagement structure 35 can be realized by alternately arranged or formed elevations and/or depressions (not labeled). Corresponding elevations and/or depressions can be arranged or aligned in such a way that the elastic element 34 interacts with them when the functional element 11 is transferred into a specific position. An expedient embodiment provides that the elastic element 34, in particular with its free end, engages in a recess when the functional element 11 is transferred to the position in which it is not possible to insert a pencil to be sharpened into the insertion area 3. In this way, the functional element 11 can also be secured in this position, which can only be overcome by the force required to move the free end of the elastic element 34 out of the depression—this results in particular from the elastic properties of the elastic element 34. In an analogous manner, as an alternative or in addition, the functional element 11 can be secured in the position in which it is possible to insert a pencil to be sharpened into the insertion area 3 .

the 39 - 41 further show that a corresponding engagement structure 35 can be a part of, e.g. B. cross-like or cross-shaped, can be control section 36, which is rotatably coupled to the functional element 11. A corresponding control section 36 can form a pin-like or -shaped or spigot-like or -shaped bearing section 11.3 for the rotatable mounting of the functional element 11 about the axis of rotation A2 or can be arranged or formed on or in such a bearing section.

Based on the 39 - 41 The exemplary embodiment shown also shows that the bearing sections 11.3, 11.4 of the functional element 11 can be designed to be oval. The bearing seats 22.3, 22.4 for supporting the bearing sections 11.3, 11.4 of the functional element 11 can be designed correspondingly for supporting respective elliptical or elliptical bearing sections 11.3, 11.4 of the functional element 11. Corresponding elliptical or elliptical bearing sections 11.3, 11.4 of the functional element 11 can also form components of a corresponding clamping or tensioning device 32.

Based on 39 - 41 It can also be seen that the bearing seats 22.3, 22.4 for supporting the bearing sections 11.3, 11.4 do not necessarily have a contour that almost completely surrounds the bearing sections 11.3, 11.4, such as B. must have a U-contour, but also a different type of contour such. B. may have an L-contour.

The fact that the principle is also conceivable with a U-contour of the bearing seats 22.3, 22.4 is shown in 42 shown embodiment.

Based on the in 39 - 41 It is therefore generally evident from the exemplary embodiment shown that a corresponding clamping or tensioning device 32 can also be realized in that the bearing sections 11.3, 11.4 of the functional element 11 have an ellipsoidal or elliptical basic shape, ie generally a rounded basic shape deviating from a circle. In this way, rotational movements of the functional element 11 about the axis of rotation defined by the bearing sections 11.3, 11.4, due to their elliptical or elliptical basic shape, can result in the functional element 11 becoming jammed or clamped in the position in which a pencil to be sharpened can be inserted into the insertion area 3 is not possible to go hand in hand. In this embodiment, a flexible body (not shown), such as. B. a cuff, be present, which (r) the functional element 11 against the insertion area 3 presses.

43 shows a schematic representation of a device 1 according to a further embodiment in an exploded view.

Based on 43 In the area to the left of the exploded view of the device 1, further geometries or basic forms of the functional element 11 are shown as examples.

A method for sharpening a pencil or pencil section to be sharpened can be implemented in each case with the exemplary embodiments of a device 1 shown in the figures. The pen can be z. B. be a writing, drawing or cosmetic pencil.

In particular, the method can include a step of transferring the functional element 11 from a closed position to an open position, a step of inserting a pencil or pencil section to be sharpened into the sharpener channel 4 via a corresponding insertion area 3 and a step of sharpening or shaping the pencil into the sharpener channel 4 inserted pin or pin section by means of the sharpening device 2 include. Likewise, the method can alternatively or additionally include a step of removing a pin or pin section from the sharpener channel 4 and a step of transferring the functional element 11 from the open position to the closed position.
