Definitions

  • the invention relates to a hand-operated pencil sharpener with a housing that collects the pointed waste and is closed to prevent the emergence of pointed waste, the insertion opening for the pencil to be sharpened also being closable by a slide against the escape of chips.
  • a sharpener of this type is e.g. B. from DE-AS 1 003 093 known.
  • the slide covering the insertion opening has to be moved by hand into the release position and after the end of the pointed process again into the closed position. This is cumbersome because it requires special manipulation by the operator. In addition, the pushing back into the closed position can be forgotten, which results in the risk of accidental leakage of pointed waste.
  • a sharpener with a collecting housing in which the collecting part carrying the sharpener can be pushed into the housing against the action of a spring until the insertion opening of the sharpener is below an insertion opening of the housing. It is disadvantageous here that the operator must constantly overcome the spring pressure with one hand during the sharpening process. If it subsides, this will result in the pin jamming, possibly even breaking off the tip that has just been produced.
  • a sharpener to be operated by hand according to the preamble of claim 1 is stored in a drawer when not in use, or in a skirt pocket or in the case of a cosmetic pencil sharpener a women's handbag is kept.
  • the escape of shavings and in particular shaved dust must be prevented to avoid contamination of the storage location by the shavings.
  • the aim of the invention is that the insertion opening is automatically opened with the insertion of the pen to be sharpened and automatically closed again when the pen is removed.
  • the invention in a pen sharpener of the preamble mentioned above primarily provides that the slide has an abutment surface for the tip of the pin to be inserted, which is shaped or runs at such an angle to the slide direction of the slide, that the pressure of the pen tip causes the slide to move into the open position, a return spring being provided for the automatic movement of the slide into the closed position, and that the abutment surface guides the pen tip to the insertion opening.
  • This automatic opening and closing of the insertion opening does not require any special manipulation by the operator, but instead takes place automatically when the pen to be sharpened is inserted and removed. So you can hold the housing with one hand and insert the pen with the other hand and sharpen it by rotating movements.
  • the inserted pin is hardly hindered by the force of the return spring, since the spring force required for moving the slide back into the closed position can be relatively low. It is also excluded that the opening is forgotten.
  • the pencil sharpener according to FIG. 1 consists in principle of the slide 1, the actual sharpener part 3, the two-part supporting part 2, the upper part 5 and the chip collecting part 6 of the housing.
  • the sharpener part 3 is held by its contours adapted recesses 7 of the side walls 8 of the support part halves 2.
  • no screw fastenings are required to hold the sharpener part 3.
  • the mine dust collects in such screw fastenings or in the holes provided for the screws and leads to contamination.
  • the dimensions are chosen so that with the abutting surfaces 9 of the two halves 2 part of the sharpener / 3 protrudes into both recesses 7 and abuts their wall. It can be seen that the separating surfaces 9 run in the insertion direction A of the pin to be sharpened and in the longitudinal center line of the slide marked by the arrows B, C.
  • Each support part half has a support surface 13, which are at the same height and on which the slide halves 1 rest, these being on the top side the top wall 14 of the supporting part halves are covered.
  • Each of the two slides 1 is provided with an abutment surface 15, which extends at such an angle to the sliding direction of the slider that the pin pressed in according to arrow A and hitting the abutment surface of the slider with its tip shifts the latter in the direction of arrow B or C.
  • This displacement takes place against the action of a compression spring 16, which is supported between the respective slider half and the respective rear wall 17 of the supporting part half 2.
  • two slide halves 1 are provided, the abutment surfaces of which extend symmetrically from above to the axis 18 of the insertion opening 10 which extends transversely to the sliding direction, so that when the pin is inserted, the latter is symmetrical about the system comes to both slider halves and moves them outwards.
  • the abutment surfaces do not have to be straight according to this embodiment, they could also be shaped differently z. B. be curved (see also the explanation of Figure 2).
  • the only essential thing is that with the insertion of the pen Via the abutment surface on the slide, a force component runs in its sliding direction, which causes the sliding process. After removing the pin, the springs 16 automatically bring the slide halves 1 back into the starting position (closed position), in which they cover the insertion opening 10. These two slide halves assume a position symmetrical to the insertion opening or the axis 18 mentioned.
  • FIG. 1 allows the support part 2 to be divided in two to make it relatively easy to spray this plastic part, including the wing halves 13, the recess 7 and the upper sides or walls 14. Only the sharpener 3 and the slider 1 are included for assembly to insert the springs 16 and to hold them by assembling the supporting part halves 2 and plugging the upper part 5 over the fully assembled supporting part.
  • the support part 2 is open at its end to be inserted into the chip collection part 6 and has from the outside and from above inside and below (based on the representation in the drawing) extending end edges 18. These end edges 18 serve, on the one hand, for the automatic centering of the supporting part to form the chip collecting part when plugged together. Secondly, they allow a screwdriver to be inserted into the supporting part from below, for example in the direction of arrow D, and thus the knife blade of the sharpener part 3 can be replaced without having to remove the sharpener part from the supporting part itself.
  • the plug-in connection between the supporting part and the chip collecting part is a sliding seat, which prevents the leakage of the pointed waste, but enables a relatively easy plugging and dismantling.
  • the end edges 19 of the upper part and 20 of the chip collecting part meet.
  • Figure 2 corresponds in principle to that of Figure 1, so that the same numbers are used for the same parts; or in the event of deviations, the respective digit was provided with a comma.
  • the support part 2 ' is in one piece and instead of the cutouts 7 has openings 7' into which the sharpener part 3 can be inserted in the direction of the arrow E until its side wall 4 is approximately flush with the outer surface of the respective support part wall 8 '.
  • the sharpener part is held by pushing on the upper part 5.
  • wavy spring parts 16 ' are provided.
  • these can be injection molded in one piece from plastic together with the slide halves 1.
  • another elastic plastic part could also be provided, provided that it exerts the described restoring force.
  • the slider halves 1 with the spring parts 16 ' are placed from above on the wing 13 of the one-piece support part 2' here. They are held in this position by the lower surface of the upper side of the upper part 5 as soon as it is placed over the supporting part 2 '. This is easier in assembly, that is to say in the assembly of the pencil sharpener, than the lateral insertion of parts 1 in the exemplary embodiment in FIG. 1.
  • the abutment surface 15 ' is not straight here, but runs in an arc shape (see above).
  • the curvature runs outwards in such a way that a tangent placed on it runs adjacent to the insertion opening or push-through opening 10 approximately in the insertion direction A.
  • the end edges 19 'and 20' of the parts 5, 6 run approximately parallel to the end edge 18 of the support part and also abut one another when the housing is plugged together.
  • FIG. 3 shows that the slide 1 'also form an angle (96 to the plane of the insertion opening 10 of the sharpener part 3
  • the arrangement is such that the abutment surfaces 15 "here are the part of the slide which has the greatest distance from the insertion opening. This ensures that with the insertion of a pin an even greater force component in the sliding directions B 'and C' is exerted on the slide halves 1 'than in the course of the slide according to the exemplary embodiments in FIGS. 1 and 2.
  • the slider or the slider halves can be held on the support part by dovetail guides or the like (not shown).
  • Figure 4 shows a sharpener similar to the embodiment of Figure 2, except that the upper part 5 ", the supporting part 2" and the chip collecting part 6 "have a somewhat different shape.
  • the slider halves 1 are provided with a straight abutment surface 15 and have it with them one-piece corrugated plastic leather parts 16 '. They are placed analogously to Figure 2 on the wing 13, whereby they are also held by the cover while maintaining a sliding seat.
  • the sharpener part (not shown here) can be held in any manner.
  • a projecting and circumferential edge 21 in the manner of a federal government is provided, with which on the one hand the supporting part 2 "is supported on the upper end edge 22 of the chip collecting part 6".
  • the edge 21 serves as an abutment and thus a support for the lower end edge 23 of the upper part 5 ".
