Description

Device for sharpening at least one pencil Technical Field The invention relates to a device for sharpening at least one pencil, comprising a housing means delimiting a housing volume and a sharpener unit which can be arranged at least partially, optionally completely, in the housing volume, wherein the sharpener unit comprises a base body which delimits at least one sharpening channel for the pencil to be sharpened, the sharpening channel defining a sharpening channel axis. Background The respective device for sharpening at least one pencil is basically known from various embodiments of the prior art and is generally configured in such a way that the functional component for the actual sharpening process, i.e. the sharpener unit, is arranged in the housing volume of the housing arrangement, which is why the respective device is also often referred to as a "can sharpener". In view of the efforts to make the respective devices more sustainable, there is a need for new designs of devices that enable not to dispose of the whole device in a simple and practical way, but only to replace the sharpener unit, for example in case of wear and tear of the sharpener unit. To date, there has been no satisfactory design principle for this with regard to the operation of the equipment in the context of replacement of the sharpener units or the required manufacturing techniques. Disclosure of Invention It is an object of the present invention to provide an improved apparatus for sharpening at least one pencil. A first aspect of the invention relates to an apparatus for sharpening at least one pencil. Thus, the devices described herein are generally configured to sharpen at least one pencil. The device comprises a housing arrangement, which may also be referred to as a housing for short. The housing means defines a housing volume. The housing means may be designed as one or more parts. Thus, the housing means may comprise one or more housing parts or housing walls defining a housing volume. In particular, the housing arrangement may, for example, have one or more bottom walls and one or more side walls, which delimit the housing volume. The at least one sharpener unit of the apparatus may be arranged or formed in or within the housing volume, whereby the housing volume may be at least partially occupied by the at least one sharpener unit. The housing volume that is not occupied by the at least one sharpener unit and is therefore free may be configured to contain the removal material resulting from the pencil sharpening process. Thus, the housing volume may be configured to at least partially house at least one sharpener unit and to house removable material or sharpening waste resulting from the pencil sharpening process. In this respect, the housing volume may also form a receiving space for at least partially receiving the at least one sharpener unit and for receiving material removed or sharpening waste generated during the sharpening process. As described above, the housing arrangement may have one or more bottom walls and one or more side walls that define a housing volume. Thus, the housing arrangement may be configured to be open on one side, the configuration of the housing arrangement being open on one side may for example be obtained in that no (at the top) top wall of the closed housing volume is arranged or formed with respect to the one or more bottom walls. However, the housing means may comprise at least one cover member which is releasably connectable or connected to the remaining wall, in particular without causing damage or destruction, so as to cover the open area of the housing means. The at least one cover member may have at least one plate-like or plate-like wall. The at least one cover part may have at least one receiving opening, in particular in the region of the respective plate-like or plate-like wall, which enables the at least one sharpener unit to be received. The at least one receiving opening may in particular be configured to receive at least one sharpener unit in the region of a wall of the sharpener unit in which at least one insertion opening for a pencil inserted into at least one sharpening channel of the sharpener unit is formed. In addition to the at least one plate-like or plate-like wall, the at least one cover part may have at least one further side wall oriented at an angle with respect to the at least one plate-like or plate-like wall. Thus, at least one of the cover members may have a U-shaped basic shape in cross-section. At least one side wall can have a connecting section, for example, which can be positively and/or non-positively connected, by means of which at least one cover part can be releasably connected to the remaining wall of the housing device, for example, in a positive and/or non-positive manner but generally (without damage or destruction). The basic geometry of the housing means can be selected substantially arbitrarily. For example, the housing means may have a c
