    The invention relates to a device for producing a cone-shaped tip on a lead or wax pencil or a chalk pen according to the preamble of patent claim 1.
    Pencil sharpening devices, which usually have a hexagonal or round shape, are known in many designs. These simple pencil sharpening devices can be found on any desk, and their construction is simple because the cross-sectional shape of the pencils makes the tips unproblematic. On construction sites or in woodworking businesses such as carpentry and carpentry, pencils or pencils containing greasy or oily mines, e.g. NEOCOLOR pens (NEOCOLOR is a registered trademark of Fa. Caran d'Ache SA) used whose cross-section is not round or hexagonal, but substantially oval. This cross-sectional shape complicates the tips, since the surface, that is, the coat of pencils, can not be performed without special guidance about the longitudinal axis of the pin or the mine.
    Also for the tips of such carpenter pencils are known from the prior art devices. From EP 1 115 583 a pencil sharpener is known in which in a base enclosure in the longitudinal direction a concave cone is formed with a narrow area near the pencil tip end and in which at the far end centering means are arranged, which hold the shaft of the pencil centered and in the Base enclosure are rotatably mounted. The side of a slot in the concave cone area an arcuate blade is inserted. Concave tips on flat pencils can be created with this sharpener. However, this device is not suitable for use on a construction site because, when marking with a lead or grease pencil on a concrete or brick surface, its tip must be sharpened at very short intervals and often after creating a single line and, consequently, the user The sharpener has to take it out of his pocket with the first hand and with the second hand he does the sharpening process by turning the pencil in the sharpener. On the one hand, a sharpener can be easily lost in this way and on the other hand, both hands are necessarily always necessary to make the tips can. As a result, it is also not possible, for example, to hold a spirit level or the like with one hand and at the same time sharpen a dull pencil to finish a marking.
    An object of the present invention is to provide a device of the type mentioned improved so that the tips of the pencil is possible with one hand and also the insertion of the pencil in the sharpener is made possible without visual contact with the sharpener.
    This object is achieved by a device according to the features of claim 1. Advantageous embodiments are described in the dependent claims. With a fastening device attached to the side of the device, the device can be fastened or attached to a working bag or trouser pocket on the belt of the worker's pants.
    By arranged on the input side of the guide sleeve insertion funnel to be pointed pencil can be introduced in a simple manner and without exact positioning in the device. In particular, the insertion can be done without direct eye contact, which is an advantage that also on a construction site together with the rough hands of construction workers and / or gloved hands, the tips of the pencil is simplified. Particularly advantageous is the insertion funnel ,, when the device is attached to a tool bag or on the belt of the worker. In this case, both the insertion of the pencil in the device as well as the tips can be done with one hand and the second hand remains free, for example, to hold a spirit level or a lath during marking and to have to reposition the mark with a broken or worn pencil tip without repositioning , In a further embodiment of the invention, the insertion funnel is connected to the rotatably mounted guide sleeve, whereby the guide sleeve inevitably aligns with the insertion of a new or sharpened pencil, the guide sleeve on the geometry of the pencil and this can be immediately introduced exactly guided into the device.
    Reference to an embodiment of the invention will be explained in more detail. Show it:

    In Figs. 1 to 3, a housing 1 for a device 3 for the tips of pencils, in particular carpenter pencils, shown with a non-round cross-sectional shape. The housing 1 comprises a substantially cylindrical base 5, on which a conical section 7 with an axis of symmetry A and with a cylindrical portion 9 is formed. In the conical section 7, a conical interior 11 is formed, followed by the bottom of a cylindrical bore 13 in the cylindrical portion 9 connects. The base 5 has a cylindrical recess 15, which merges into the interior 11. The recess 15 is at least two locations, preferably three areas, radially outwardly broken, i. in the base 5 radially extending openings 17 are formed. In addition, over a range of about 190 to 200 degrees on the base 5, a circumferential groove 19 is recessed.
    At the conical portion 7, a slot 21 is inserted in the fall line and the side of the slot 21, a blade 23 connected to the jacket 39 of the conical portion 7. The cutting edge 25 of the blade 23 partially covers the slot 21 and protrudes a few tenths of a millimeter into the conical interior 11.
    In the circular cylindrical recess 15 in the base 5 (see Fig. 5) is created space for a guide sleeve 27 having a substantially oval guide opening 29. The guide sleeve 27 may be completely within the cylindrical recess 15 in the base 5 or this partially overtop. On the shaft 31 of the guide sleeve 27 a circumferential recess 33 is formed, in which an elastic retaining clip 35 engages with guide cam 36 when it is inserted into the groove 19 on the base 5. The retaining clip 35 secures with the guide cam 36, the guide sleeve 27 in the base 5 and allows the guide sleeve 27 to rotate in the base 5.
    On the guide sleeve 27, a funnel 37 is formed on the inlet side, the inlet side preferably has a circular cross-section and above the guide opening 29 on the guide sleeve 27 has a cross-section corresponding to the guide opening 29, i. is formed substantially oval. The cross section of the funnel 37 in the inlet region preferably corresponds to the cross section of the base 5 or it is still slightly larger. Alternatively, the funnel 37 may be formed directly on the base 5, wherein the funnel outlet side is formed circular over the guide opening 29 of the guide sleeve 27.
    On the jacket 39 of the base 5, an L-shaped bracket 41 is attached. The shorter leg 43 of the retaining clip 41 may be part of the base 5 or be clamped firmly clamped to this. The headband 41 can consequently be made of plastic, such as the device 3, or of metal.
    The width of the retaining clip 41 preferably corresponds approximately to half the diameter of the base 5. The length of the longer leg of the retaining clip 41 corresponds approximately to the length of the device 3 without funnel 37.
    The operation of the device 3, i. of the sharpener, circumscribed. The device 3 is preferably plugged into a tool bag of a construction worker or at his pants belt and held against rotation by the headband 41. A new unsprayed pencil or a blunt pencil can now be inserted into the funnel 37, without the need for direct eye contact. By turning the pencil this is guided into the guide opening 29 of the guide sleeve 27 and then guided by the guide sleeve 27 exactly axially along. Upon further advancement of the pencil reaches the front edge in the region of the blade 23 and it is the coat 39 is sharpened around the face of the pencil and then the expression at an angle of the blade 23. In a blade 23 with inlet side straight cutting edge 25 thus results in a circular conical pencil tip; if the blade 23 at the outlet side at least partially arcuate, so the expression on the end of the pencil can be shaped differently.
    The separated at the tips coat 39 of the pencil can fall directly to the ground, so that no obstruction outside the blade 23 may occur or a collection vessel must be emptied.
