Definitions

  • the invention relates to a device with the preamble of claim 1 characteristics listed.
  • An essential part of pencils to be sharpened is their central mine, to avoid contamination of the user 's hand is encased in a peelable material.
  • This material is conventional mostly made of peelable wood, a paper tube or the like.
  • the mine diameter such pens differ according to the purpose large.
  • the pen refill is subject to permanent use Wear that causes the tip of the mine to become dull. That changes the typeface and to regenerate the pen tip is the pen by means of the sharpener tipped at regular intervals. It is therefore for the user of the Pen desirable, the pen or lead sharpener permanently in an easily accessible To have closeness.
  • Sharpener commonly used for sharpening are simple bulk items in different versions. Same in terms of a design feature such sharpener. They contain a conical end of their pin guide channel flanking peeling knife for conical peeling of the to be sharpened Pin end. This sharpening serves primarily to the desired Sharpening or shaping of the conical area towards the end of the writing rejuvenating mine.
  • the invention has for its object a universally usable device to create, which enables the pen user to do the regular necessary Regeneration of the pen tip required sharpener available at hand to have. This object is solved by claim 1.
  • the device according to the invention is a plug-in adapter that is simple, but captive to that which is not necessary for the intended use of the pen Back end of the pin can be plugged on and put on there and the sharpener cannot be lost, however releasably holds for its use.
  • Adhesion of the device to the rear end of the pin and on the other hand also The elasticity of the contraction serves to ease their solubility of the device material at the end of the attachment and its adhesive effect favorable coefficient of friction. This makes it e.g. the one to put on the cap or sleeve provided at the rear of the pin is also easily possible, to adapt itself to different circumferential shapes of the pen. It is namely, usual to give pins not only a cylindrical peripheral shape.
  • Shaft cross sections in the form of mostly an equilateral hexagon or also elliptical Cross-sectional shapes are common and other, even irregular cross-sectional shapes are common.
  • the device according to the invention is intended be applicable as independently of the cross-sectional shape of the stem as possible and that also enables the rubber-like elasticity and contractility of the device material.
  • the retaining projection of the device according to the invention comes with the conventional tapering in the insertion direction of the pointed pointed channel end opposite.
  • the retaining projection basically fits independently from its circumferential shape to a large number of common sharpener.
  • the desired adhesive closure is irrelevant. It is only essential that such a liability is concluded and this is the rubber-elastic consistency of the device material conducive. It ensures the necessary clamping or adhesive pressure at the clamping point and makes the desired adhesive effect largely independent of the circumferential shape of the holding projection.
  • segmenting the Holding projection can be the radial spring behavior of the Hold tabs affect and vary.
  • the segments of the tab are like expanding jaws of an expanding chuck on the outer surfaces of the peeling cone of the pencil guide channel of the sharpener and adapt even better different forms of sharpener, especially their pointed channels.
  • the pin 1 contains a pin mine 3 which is concentric with its longitudinal axis 2 and which is used for better grip and as protection against contact also concentric to Longitudinal axis 2 of an envelope 4 made of peelable material, e.g. wooden, Cardboard or an appropriate plastic is surrounded.
  • the top 5 of the Pin mine 3 protrudes out of the envelope 4.
  • the front Writing end 6 of pen 1 tapers towards the front end of the lead 7 conical.
  • a holding device generally designated 14 On the rear end 13 of the envelope 4 facing away from the mine end 7 a holding device generally designated 14 can be placed.
  • the holding device has on its in the placement position of the mine tip 5 facing side 15 a cap or sleeve 17 surrounding the plug opening 16 with in the plug position (Fig. 1; 4, 6 and 7) of the mine tip 5 facing the opening edge 18.
  • the holding device contains on its holding side 19 facing away from the attachment side 15 a retaining projection 20 for releasably adhering engagement in the pin guide channel 9 of the sharpener 8.
  • the holding device is a one-piece molded body 21 (Fig. 2,3).
  • the holding projection 20 contains four in the manner of the rods of a bundle of lictors positioned next to each other, of the same size and preferably of the same design Projection segments 22. They are radial to the projection direction 23 of the longitudinal axis 2 of the molded body 21 spaced apart (spacing gaps 27 in Fig. 1 to 3) and the same size and the same design.
  • the associated writing end 6 placed position surrounds the placement cap 17th a cavity that exposes the exposed mine tip 5 to the ambient atmosphere ab emphasize.
  • the outer circumference of the projection segments 22 forms parts approximately one of the longitudinal axis 2 of the molded body 21 and thus of the retaining projection 20 concentrically surrounding circumferential jacket, in particular Cylinder jacket.
  • the holding projection 20 has between its outer spread fixing area in the axial direction 24 and its attachment end 15 have a radial constriction region 25.
  • the inner diameter 26 of the mounting or push-on opening 16 of the holding sleeve 17 slightly diverges from its inner end toward the fitting opening 16 facing outer end.
  • the attachment opening 16 is at her Opening side surrounded by the opening edge 18.
  • a further development feature is that the material of the molded body 21 that can be an eraser.
  • the molded body 21 can thus be outside use its hold function as an eraser.
  • This additional or The holding body can be used at least occasionally without impairment its holding function particularly satisfactorily meet if he is not used too intensely and not too often for etching becomes.
