    MANUAL SHARPENING DEVICE FOR A SAW BLADE OR SAW CHAIN FIELD OF THE INVENTION
    The invention relates to a sharpening device for serially arranged saw teeth of a saw blade or a saw chain with the features of the preamble of claim 1.
    STATE OF THE ART
    Sharpening devices for saw blades are known in particular in the form of CNC devices that are expensive to purchase. By such a device, a uniform sharpening tooth to tooth on the saw blade is possible, which ensures safe operation of the saw blade.
    For sharpening saw blades and saw chains manual file holder are also known, which allow tightened clamped to attach a file about a rotation axis on a file to be filed. In these file holders usually round files are held, the angle of the file holder is basically predetermined by the position of the pivot axis. An angular adjustability is thus given only to a limited extent.
    OBJECT OF THE INVENTION
    Based on this prior art, the present invention seeks to provide a cheap manual sharpening device for sharpening saw blades and saw chains, which nevertheless allow individually adjustable sharpening.
    This object is achieved by a manual sharpening device with the features of claim 1.
    The sharpening device has to a saw blade storage or saw chain storage, wherein the file holder is deliverable relative to this storage along a rail and lockable. Preferably, a plurality of rail bearings and Winkelverstellmechanismen are provided so that a multi-dimensional adjustment and delivery of the file to be sharpened sawtooth not only possible but also reproducible from sawtooth to sawtooth. By assigning saw blade or saw chain to the file holder in a fixed system and the additional possible high degree of adjustability manual sharpening device is created, which allows a safe resharpening of saw blades and saw chains, especially for home and craft, without resorting to complex CNC devices must become.
    The repeatable from sawtooth to sawtooth positioning is preferably supported by the fact that a locking indexing is provided in which engages a locking element in each case in the tooth gap between the teeth. As a result, a repeatable position can be reliably ensured from tooth to tooth, without causing undue tension on the saw blade or saw chain. If the saw blade is rotated further by one tooth, the locking element engages in the following tooth. Thus, the next tooth is in the same place during the filing process as the previous one.
    Preferably, a saw blade holder is further provided which holds the saw blade near the sawtooth to be sharpened. This ensures that when filing the saw blade does not begin to vibrate due to vibrations, i. The saw blade is again held transversely to its surface by the saw blade holder at a small distance from the sawtooth.
    Further advantages will be apparent from the subclaims and the following description of preferred Ausführungsbelsplele.
    BRIEF DESCRIPTION OF THE FIGURES
    In the following the invention will be explained in more detail with reference to embodiments illustrated in the figures. 1 shows a three-dimensional view obliquely from above of the manual sharpening device according to the invention with a saw blade arranged thereon, FIG. 2 shows a representation according to FIG. 1 in a view from the right front, [0013] FIG. 3 is an illustration of the sharpening device according to FIG. 1, fixed on a
    Vise, Fig. 4, 5 is a manual sharpening device for a saw chain in a dreidimensio nal representation of the side and obliquely from above.
    DESCRIPTION OF PREFERRED EMBODIMENTS
    Before the invention is described in detail, it should be noted that it is not limited to the respective components of the device and the respective method steps, since these components and methods may vary. The terms used herein are intended only to describe particular embodiments and are not intended to be limiting. In addition, if singular or indefinite articles are used in the specification or claims, this also applies to the majority of these elements unless the overall context clearly makes otherwise clear.
    Figures 1 to 3 show a manual sharpening device for a saw blade 11, Figures 4 and 5, a sharpening device for a saw chain 12, wherein the structure of the two sharpening devices for sharpening serially arranged saw teeth 10 for both the saw blade 11 as well the saw chain 12 is substantially identical. The sharpening device has a file holder 13 provided with a depth stop 30, which can be delivered to the respective saw tooth 10 to be sharpened. On the file holder 13, a file 14 is fixed in a variable position, wherein the file holder 13 is rotatable about a pivot axis 15. Preferably, a file such as e.g. a diamond file is used as a file 14 in the file holder 13. With the file holder, the file 14 is movable in a direction of filing s-s.
    At the sharpening device a saw blade bearing 16 or saw chain bearing 17 is provided, against which the file holder 13 is deliverable and lockable. For this purpose, the file holder 13 is guided lockable on the sharpening device in a guide rail 18. The pivot axis 15 is in turn mounted on an adjusting mechanism, on the one hand has a height adjustment 19 in the form of a rail, which is lockable on the guide rail 18. The file holder 13 is guided longitudinally adjustable in the guide rail, which initially allows adjustability and adaptability to the diameter of a saw blade 11, which is rotatably supported according to FIG. 1 to 3 on the saw blade bearing 16 as a bore of the holder 29 or the guide rail 18.
    Between guide rail 19 and pivot axis 15 for the file holder 14 is preferably at least one Winkelverstellmechanismus, in the embodiment, two Winkelverstellmechanismen 20,21 are provided by the angle of the file holder 13 to the sawtooth 10 is adjustable and lockable. If necessary, for further determination, a further Winkelverstellmechanismen on the two Winkelverstellmechanismen 20, 21 also be used. Thus, the file holder 13 is adjustable in height and angle, so that it is adjustable to the geometry of the sawtooth 10 to be ground.
    The sharpening device further comprises a holder 29, on which the guide rail 18 as shown in FIG. 3 and the saw blade bearing 16 or saw chain bearing 17 are provided. This holder may e.g. be fixed to the vise 24 of a workbench.
    In particular, Figures 3 and 4 show that in addition a locking indexing 22, 22 'provided by the sawtooth 10 to 10 sawtooth repeatable positioning of the sawtooth 10 is provided. The latching indexing 22, 22 'has for this purpose a spring-loaded latching tooth 23 which engages in the tooth spaces 10a of the saw blade 11 or the saw chain 12. By the Rastindexierung 22, 22 ', the saw blade from sawtooth to sawtooth 10 are rotated, wherein the spring-loaded locking tooth 23 engages in each tooth gap after the saw blade 11 or the saw chain 12 has been further rotated by one tooth. Thus, the ratchet indexing 22, 22 'ensures that each tooth to be sharpened is at the same location during the filing process.
    In addition, a detachable blade holder 24 is provided which holds the saw blade 11 near the sawtooth 10 to be sharpened. This ensures that when filing the saw blade 11 does not begin to vibrate due to the vibrations, i. the saw blade is again held transversely to its surface at a small distance from the sawtooth 10 to be sharpened. The indexing 22 is mounted on the saw blade holder 24. Saw blade bearing 16 and saw chain bearing 17 are preferably provided on the guide rail 18 or on the holder 29.
    For the saw chain 12, a guide rail 26 is provided for guiding the saw chain 12 according to Figures 4 and 5, wherein a rotatable sprocket 25 meshes with the saw chain for movement of the saw chain. The locking indexing 22 'is arranged on the bearing 27 of the sprocket 25.
    The mechanical structure of the sharpening device thus allows in conjunction with the holder 29 to fix the sharpening device on a workbench, but at the same time adjust the geometric relationship between the file and sawtooth reproducible, so that a manual low-cost sharpening device is created with high precision of Tooth to tooth leads to a repeatable sharpness result.
