Definitions

  • the invention relates to a combination device consisting of sharpener and eraser, which is used on the one hand for sharpening pens or colored pencils and which on the other hand allows writing or drawing traces of pencils or colored pencils to be erased by erasing.
  • sharpeners have been known for a long time and are produced in different configurations depending on the intended use.
  • the simplest version consists of the parts mentioned, in which case the waste which arises during the sharpening emerges in the area of the sharpening knife and can be collected or removed in any way.
  • the sharpener is arranged in a container which catches the waste and which has to be emptied from time to time. All sharpener designs of this type have in common that the devices serve only a single purpose, namely the sharpening of pens or colored pencils, be it in wood or plastic-framed form or as a bare lead.
  • a sharpener is combined with an eraser, so that these two auxiliary devices, which are required for drawing or writing, are always at hand.
  • An eraser-sharpener combination described in the literature emerges, for example, from German utility model 87 02 403.
  • the sharpener is arranged in a container on which there is another chamber in which the eraser is arranged.
  • the eraser is attached to a lid, which is usually this one Closes the chamber so that the eraser is completely in this chamber.
  • the lid can be removed, turned through 180 ° and put back on, so that the eraser protrudes outwards and is ready for use.
  • Such combinations of devices have the disadvantage that they are relatively voluminous and since a significant proportion of the total volume cannot be used for the function of the eraser.
  • the invention is based on the object of proposing a new concept for such sharpener-eraser combinations, in which a larger proportion of the total volume can be used as an erasable surface.
  • the sharpener is arranged inside the eraser. Due to this concept, the sharpener disappears completely in the eraser, so that the eraser can be used practically on its entire surface for its actual purpose.
  • the invention can now be implemented in various ways. On the one hand, it is possible to permanently arrange the sharpener inside the eraser. This concept, which in turn allows different variations, is appropriate if the dimensions can be chosen so that the life of the sharpener in normal use corresponds approximately to the life of the eraser, also provided normal use.
  • the sharpener removably in the eraser, the eraser only serving as a case for the sharpener.
  • This embodiment can be implemented in such a way that the sharpener is equipped with a drawing tape which makes it easier to remove the sharpener from the eraser. At the outer end of the drawing tape, a plug can then be arranged with which the opening of the Ra rubber can be locked when the sharpener is inserted. Further embodiments of this concept idea are explained further below.
  • the eraser can have any external shape. In the simplest case, it is a cuboid block, as it is known per se for erasers. On the other hand, the eraser can also have the shape of a figure, for example a bear, an elephant or the like. are given. Such forms of imagination are particularly suitable for performances that are primarily intended for children or schoolchildren.
  • the eraser in the area above the inserted sharpener is significantly harder than in areas away from it. This can be used for fine erasing, especially for very small areas, lines or dots. In such cases, the hard-supported eraser mass shows a significantly more favorable behavior than the other softer areas of the rubber.
  • the eraser have an exit opening in the area of the sharpener, which opening is closed with a removable container.
  • This container is used to hold the waste that is generated during sharpening.
  • the container can have the shape of a trough, on the edge of which there are extensions which can be inserted into openings in the eraser.
  • a cavity in the eraser which is significantly larger than the sharpener and which serves as an accommodation space for the sharpener and also as a chip collecting container.
  • a plate made of hard material for example made of plastic or aluminum or another suitable metal can then be arranged on an outside of the eraser, which serves as a holding plate for the sharpener and also as a closure for the cavity mentioned.
  • the plate can be equipped with clamping tongues which engage in clamping openings of the eraser in the assembled state of the combination device. In this way it is easily possible to remove the plate together with the sharpener from the eraser and to pour out the chips that have accumulated in the interior of the cavity during use.
  • the opening of the cavity, which is closed with the said plate can be in one embodiment on an end face of the eraser. In such a case, it is favorable to arrange the insertion opening for the pins to be sharpened in the holding plate.
  • the opening of the cavity and thus the holding plate can be located on a broad side of the eraser. In this case, it is favorable to arrange the insertion opening for the pencils to be sharpened in an end wall of the eraser.
  • this consists of two eraser plates which are arranged one on top of the other when in use.
  • the sharpener is in one eraser plate embedded in the eraser. Only in the area of the pointed knife is a small opening arranged as a chip passage window.
  • In the other eraser plate there is a cavity which is open on the broad side which, when assembled, lies on the inside.
  • the two eraser plates are connected to one another by plug connections or additionally by at least one film hinge. When the device is assembled, the sharpener cannot be seen from the outside and all outer surfaces are made of eraser compound. To remove the chips that have accumulated in the cavity of the one plate, the two plates are removed from one another and can be reassembled after cleaning the cavity.
  • the eraser can also consist of two eraser plates, a cavity being arranged at least in the one plate which receives the sharpener, which cavity is substantially larger than the outer dimensions of the sharpener. This cavity then serves to receive the sharpener and at the same time as a chip collection container.
  • the other plate does not necessarily have to have a cavity. However, such a cavity can also be provided there.
  • the two plates are then assembled in the same way as previously described, being designed as a case for the removable sharpener arranged in the one cavity.
  • a passage opening for the insertion of the pen to be sharpened can be provided in an end or side wall of the eraser. This is not essential if the arrangement is such that the sharpener must always be removed for etching.
  • the customary eraser materials are outstandingly suitable for realizing the invention. It has surprisingly been found that permanent erosion of the eraser surface from the sharpener drop does not occur. Should still in To prevent this further, it is proposed that the surface of the eraser has a dirt-repellent layer in the region of the outlet opening. This layer can consist, for example, of a thin polyethylene film which is arranged on the surface of the eraser in the area mentioned.
  • the masses known for erasing purposes are suitable for the production of the eraser, and particularly good results have been achieved with eraser masses based on polyvinyl chloride but also on the basis of natural rubber.
  • FIGS. 1 and 2 are each designated as a whole by 1. It consists of the eraser 2, which has the shape of a cuboid in the embodiment according to FIG. 1 and the shape of an animal figure (shown from behind) in the embodiment according to FIG. 2.
  • a sharpener 3 is arranged in the interior of the eraser 2, the sharpener inlet opening being at 4 and the sharpener knife at 5.
  • the pointed entry opening (not visible in the drawing) is located on the underside of the animal figure; the sharp knife can be seen at 5.
  • the outlet opening 6 for the sharpener waste is closed with a removable container 7 when in use.
  • the container is removed and shown separately in Fig. 3.
  • the sharpener is inserted into the eraser in the embodiment shown that there are corners 14 or protruding points 15 in the areas supported by the sharpener, which are harder than the rest of the eraser mass due to the support and are therefore particularly suitable for fine erasing.
  • the container 7 shown as an embodiment has the shape of a tub, on the edge 8 extensions 9 in the form of legs, flags or the like. are present, which can be inserted into correspondingly shaped openings 10 of the eraser 2.
  • FIG. 2 also shows a dirt-repellent layer 11, which covers the outlet opening 6 of the Erasers 2 surrounds.
  • This layer can be a thin polyethylene film which is laminated on at the point shown.
  • the layer is not indispensable, but it has the advantage that the eraser cannot accept any graphite or paint dust at the covered areas.
  • the conceptual idea on which the invention is based can be implemented in two ways.
  • it is possible to permanently store the sharpener in the eraser on the other hand, it is possible to design the eraser only as a case for temporarily storing the sharpener.
  • the sharpener must be removably arranged in the eraser. So that the sharpener can be removed more easily from the container, it is proposed that the sharpener be equipped with a drawstring 12.
  • This drawstring can be a plastic thread or a metal chain or the like. be.
  • a sealing plug 13 can be arranged at its outer end, with which the upper opening, into which the sharpener is inserted, can be closed.
  • the inner wall of the eraser opening is covered with a layer whose friction behavior is small compared to the surface of the sharpener housing.
  • a suitable plastic film for example a polyethylene or polypropylene film, or a thin layer of tetrafluoropolyethylene is also proposed for this purpose.
  • the eraser 2 has a cavity 16 which is significantly larger than the sharpener 3 and which is used as an accommodation space for the tip zer and also serves as a chip collection container.
  • a plate 17 is arranged on an outside of the eraser, which serves as a holding plate for the sharpener and as a closure for the cavity 16.
  • This plate is made of hard and rigid material, for example plastic, or a suitable metal.
  • the plate is equipped with clamping tongues 18 which engage in clamping openings 19 of the eraser in the assembled state of the combination device.
  • the opening of the cavity 16 and thus the holding plate 17 is located on an end face of the eraser 2. In this case, it is advantageous to arrange the insertion opening 20 for the pencils to be sharpened in the holding plate 17.
  • the opening of the cavity 16 and thus the holding plate 17 is located on a broad side of the eraser 2.
  • FIGS. 6 and 7. Another embodiment of the combination device is shown in FIGS. 6 and 7.
  • the device consists of two eraser plates 2 'and 2 ⁇ .
  • the sharpener 3 In the area of the sharpener 5 there is a passage window 21 for the chips formed during sharpening.
  • the other eraser plate 2 ⁇ In the other eraser plate 2 ⁇ there is a cavity 22 which is open to that broadside which is inside when assembled. The cavity 22 serves as a chip collection space in use.
  • the two eraser plates 2 'and 2 ⁇ are by plug connections, for example the extensions 9, which engage in openings 10 in the assembled state or additionally connected to one another by at least one film hinge 23.
  • the insertion opening is located in both cases shown in FIGS. 6 and 7 20 for the pencil to be sharpened in one end of an eraser plate 2.2' 2,2.
  • the eraser is designed as a case for the sharpener.
  • the case is opened by simply lifting off the upper eraser plate 2 'as a whole.
  • the sharpener 3 arranged and clamped inside can then be removed for use as a whole.
  • the upper eraser plate 2 ' is connected to the lower eraser plate 2 ⁇ via a film hinge 23.
