Definitions
- the invention relates to a so-called container sharpener with the preamble of the features listed in claim 1 (DE 27 45 600 A1).
- the detachably fixed hood serves as chip catcher for the peeling waste. It prevents unwanted pollution of the environment Tips before.
- the invention has for its object this problem by technical means to solve, which is the basis for manufacturing the casing in rational Creates quantities.
- This object is solved by claim 1.
- the molded projections are designed so that they can either be used for clamping or Snap fixation of a small-format sharpener by applying sener External walls from the outside in or a large-format sharpener Spreading pressurization of wall areas of its housing from the inside outwardly between them. For the application of the expansion pressure it is of course necessary that the exposed wall areas of are accessible from the outside for the projections.
- Claim 2 embraces the fact that the pointed case is straight injection molded thin-walled from large-format sharpeners mostly from plastic are. This is initially necessary for injection technology reasons, sink marks to prevent. It also saves material. This leads to, that especially the case of large-format sharpener one on its outside jagged case bottom, from which the side walls of the pointed case project freely downwards from home. That gives it on one Stand-up stand-up sharpener has a compact design and creates inherently the possibility of freely projecting towards the bottom Side walls of the sharpener housing through the molded projections of the bottom part of the To reach behind the casing (claim 2). As a result, the invention takes advantage of circumstances with large-format, mass-produced lace, which thereby their intended use according to the invention within an envelope housing do not have to be adjusted individually.
- Claim 3 includes a special design of the projections, which in precise positional positioning in a simpler, but technically particularly effective manner of the respective sharpener within the casing.
- claim 4 relates to a particularly effective embodiment of the clamping or Snap fixation when clamping a large-format sharpener revealed.
- the of Intended for fixing the cover of the casing Form surrounding wall or parts of such a surrounding wall of the bottom part together with the projections protruding upwards from the base part a clamping groove, between the side walls of which over the case bottom the large-format sharpener protruding down the side walls can be clamped particularly effectively. That comes from position security the positionally fixed, large-format sharpener on the bottom part of the casing. This will act on the sharpener or the sharpener housing when sharpening Peak forces are particularly well absorbed. A loosening of the sharpener within the casing is not to be concerned about even with strong vibrations.
- the sharpener unit optionally contains a large-format pencil or lead sharpener 1 or a small-format sharpener 2 and the respective sharpener 1 or 2 surrounding and fixing envelope 3.
- This envelope 3 is in turn from a base part 4 and a hood 5.
- the hood 5 can be clamped to the bottom part 4 with its lower edge region 6.
- the hood 5 with its edge region 6 is over the base 7 of the bottom part 4 protruding upwards, in the embodiment all around self-contained surrounding wall 8 slipped over.
- the dimensioning of the The edge area 6 of the hood 5 in relation to the surrounding wall 8 is hit that the hood 5 with the edge area on the outer surface of the surrounding wall 8 sits tight in the form of a clamp seat.
- the hood 5 is precisely positioned with its lower edge 9 on the outer surface or the outer cover surface 10 of the base 7.
- a U-shaped clamping rib 11 also stands out of the base 7 of the base part 4 upwards.
- the U-shaped clamping rib 11 is within the Surrounding wall 8 delimited room arranged.
- the two U parallel legs 12, 13 of the clamping rib 11 protrude with their free ends into the middle of the base 7 into it.
- the crosshead 14 of the U-shape of the clamping rib 11 runs forming a spacing gap 15 parallel to the adjacent part of the surrounding wall 8.
- the same spacing gap 15 is between the parallel legs 12, 13 of the U-shape of the clamping rib 11 on the one hand and the inner surfaces the surrounding wall 8 or that forming part of the surrounding wall 8 Corner base 16 recessed
- This spacing gap 15 is used for clamping the lower ends 17 of the side walls 18, 19 and the rear wall 20 of the housing of the larger sharpener 1.
- the lateral resilience of the parallel legs serves 12,13 and the crosshead 14 also the fixation of the smaller sharpener 2 in Contact the inside walls of the parallel legs 12, 13 and the crosshead 14. This fixation is also a tension connection.
- the front side 23 of the hood 5 is penetrated by the through opening 24.
- This lead-through opening 24 is at the level of the attachment edge 9 of the hood 5 open. It can be closed by a blind 25.
- the blind 25 is on the inside 26 of the hood 5 in longitudinal guides 27, 28 guided for longitudinal displacement.
- At the The outer end of the blind 25 is an integrally formed protruding outward Handle projection 29 on the one hand for opening and closing actuation of Hand and on the other hand as an envelope stop in both opening and in Closed position.
- the base part 4 is also provided with receiving slots 30, 31 for a cleaning stick 32 provided.
- the receiving slots 30, 31 are as clamping slots effective.
- the cleaning stick 32 is also from the environment shielded below the hood 5. Its handle end 33 is in the fixing position within a shielded opening 34 on the bottom part 4.
- the large-format sharpener 1 is special from its bottom side good to see.
- This view shows the rugged structure of the bottom of the Sharpener housing 35 of the large-format sharpener 1.
- It is a plastic injection molded part, the outwardly compact side walls 18, 19, the rear wall 20 and its front wall 37 in which the opening 36 of the pointed channel bears are thin-walled and with their peripheral edges 38 a footprint for the pointed housing 35 on the surface 39 of the bottom part 4 form.
- the side walls 18, 19 and Rear wall 20 of large-format sharpener 1 clamped in spacing gap 15, which between the clamping rib 11 and its parallel legs 12, 13 on the one hand and the surrounding wall 8 and the corner base 16 on the other hand is. This clamping ensures that the position is secured even when shaken on the bottom part 4.
