Definitions

  • the invention relates to a sharpener for pencils, crayons, cosmetic pencils or the like, with an essentially cuboid sharpener housing and with mounting devices for fastening a further sharpener.
  • Such sharpeners have become known in a wide variety of designs and sizes, the size of the sharpener, the angle of inclination of the sharpener knives and the size of the inlet and outlet opening of the sharpener channel largely depend on the pins to be sharpened. It is not only the diameter of the pens that is important, but you also use different sharpeners with the same pen diameter when it comes to pens with differently hard leads. For example, the sharpener for a cosmetic pencil with a soft, lubricating lead must be designed quite differently than a sharpener for a pencil with a very hard lead.
  • Double sharpeners have already become known for joint use in a specific field of work, which mostly comprise single sharpeners with different sharpening channels for sharpening pencils of different thicknesses, but also for sharpening either lead or colored pencils.
  • these multiple sharpeners are fixed from the outset to a specific combination, so that it is not possible for a user to acquire and use a multiple sharpener with two or more specific single sharpeners as a common component.
  • the invention is therefore based on the object of providing a sharpener which enables any construction of multiple plugs.
  • the longitudinal side walls of the sharpener housing are provided with complementary projections or depressions which enable two identical sharpener to be plugged together.
  • the sharpener housing Due to the inventive design of the sharpener housing, a variety of otherwise quite different sharpener can optionally be connected to one another, the design of the longitudinal side walls being designed so that the projections or depressions of different sharpener are so differently formed in groups, with very particular advantage, that only related sharpener can be connected to each other.
  • the profiling of the longitudinal side walls can have longitudinal or transverse ribs, the shape and thickness of which corresponds in each case to the shape and thickness of the intermediate grooves on the opposite side, so that two sharpener are clamped together when they are plugged together.
  • the ribs have a trapezoidal shape that widens outwards Have cross-section, so that either the plugging together only by overcoming a corresponding deformation force of the trapezoidal ribs or preferably by parallel displacement in the direction of the longitudinal axes of the ribs and thus pulling apart is difficult. It can also be advantageous to provide a taper of the ribs and intermediate grooves in the longitudinal direction, so that wedging also occurs in the mating direction in the above-mentioned sliding into one another, so that a particularly solid and not readily separating unit is formed.
  • knobs on one longitudinal side wall and receptacle bushings on the other longitudinal side wall could take place analogously to the formation of so-called clamping modules.
  • the sharpener shown in FIGS. 1 and 2 comprises a conventional cuboid sharpener housing 1 with a sharpener channel 2, the inlet openings of one housing end wall 3 and the outlet opening of which is arranged in the opposite end wall 4 and the conical flank of which is arranged tangentially to the cutting edge of a sharpener knife 5.
  • the longitudinal side walls 6 and 7 are provided with complementary transverse ribs 8 and intermediate grooves 9 or transverse ribs 8 'and intermediate grooves 9', so that two sharpener - as can be seen in Fig. 2 - can be clamped together laterally and thus form a structural unit .
  • any unit can also be formed from three or more sharpeners, which should preferably be sharpeners that each belong together, for example for sharpening pencils of different diameters or also of different cosmetic pencils or differently colored cosmetic pencils.
  • the ribs 8 ′′ can have a trapezoidal cross section that widens outwards.
  • longitudinal ribs 8 ′′ ′′ extending in the longitudinal direction of the pointed channel 2 can also be provided, as shown in FIG. 4.
  • knobs 8 '' '' can also be provided for engaging in corresponding sleeves 9 '' '(cf. FIG. 5).
  • a chip catch box 10 is provided in the exemplary embodiment according to FIGS. 6 and 7, which is narrowed relative to the sharpener housing in such a way that its longitudinal side walls 11 and 12 sit on the top of the sharpener and the ribs are fully to the side protrude so that the chip box 10 does not hinder the joining of two sharpener.
  • the end walls 13 and 14 of the chip collection box 10 are extended downwards and provided with a latching bead 15 which engages in a corresponding latching recess 16 of the pointed channel inlet and outlet end walls in a locking manner.
  • the invention is not restricted to the exemplary embodiments shown.
  • a taper of the ribs and grooves in the longitudinal direction could also be provided if longitudinal or transverse ribs were provided, in order to be able to achieve an increased clamping lock in the plugging direction when plugging together, which in connection with 3 a separation of several plug-in sharpener in all directions is reliably prevented, so that an unwanted separation cannot take place.
  • inclined cuboids are of course also meant, i.e. the usual insertion sharpener with a wedge shape, in which the top surface and the bottom surface are inclined with respect to one another so that they are tensioned into a loop Pupil case can be inserted.
  • This wedge shape has nothing to do with the fact that the two longitudinal side walls can be formed parallel to each other.
  • the configuration of sharpener according to the invention is also very advantageous for a different type of holder in student pencil cases instead of the holder loops already mentioned in the previous paragraph, which also requires essentially wedge-shaped sharpener housings.
  • the sharpener can be attached by simply attaching it to the plate or rail which is held in the student's case by means of loops, and can thus be held very easily and securely.
  • the rigid or detachable mounting of the plate or rail in the pencil case by gluing or with the help of loops is much easier to implement than a mounting using a loop overlapping the sharpener, since this expands over time and thus the mounting function is lost.
  • the profiling of the pointed side surfaces according to the invention is also very simple in order to hold such a sharpener in other containers, in particular also in cans, so that can sharpener with different chip collecting cans can be equipped very easily with the associated sharpener. All that is then required is a counter surface on the inside of the box in order to attach the desired sharpener, which of course must then come to rest with its pointed opening exactly under the corresponding insertion opening of the box, for example the box lid.
