Definitions

  • the invention relates to a device for sharpening knives, scissors or similar cutting tools with at least one abrasive grinding element, which is arranged against spring force in a housing. (please refer e.g. US-A-2 241 412).
  • a knife sharpener is known, the two in one Plastic housing parallel and offset against each other, rotatably mounted Grinding bodies in the form of grinding wheels, which deflect resiliently can.
  • the knife edge to be sharpened is from above in the by the two circular grinding wheel formed transverse to the longitudinal extent of the Housing inserted and applying a compressive force relative to the Grinding wheels moved.
  • the invention has for its object to provide a grinding device of the type defined, which enables simple grinding of knives, scissors or similar cutting tools, while avoiding the disadvantages described above, in particular if these cutting tools have a cutting edge that deviates from a straight line.
  • the solution to this problem by the invention is characterized in that the grinding element is strip-shaped and is arranged on a sheet-shaped carrier, which in turn is resiliently guided on the housing.
  • the grinding element Due to the strip-like design of the grinding element and its arrangement on a leaf-shaped, resiliently guided support on the housing Possibility to put the blade of the cutting tool under the desired one Lead grinding angle relative to the grinding element, the movement being a both in the longitudinal direction of the grinding element and also transverse to it Component includes. Due to the resilient guidance of the grinding element on Housing, the grinding element is able to avoid limited, so that the grinding surface of the existing cutting geometry of the cutting tool adapts. In this way, cutting tools with one of a Straight cutting edge, especially a concave or convex curved cutting edge - also with a changing one along the cutting edge Curvature - be ground reliably.
  • the leaf-shaped carrier at least at its ends via a spring on the housing, which results in a particularly simple construction.
  • the leaf-shaped carrier can be as one end formed on the end of the strip-shaped grinding element be formed which is resiliently guided in the housing via a spring. This configuration results in a particularly simple design.
  • the leaf-shaped carrier is fixed to the housing and designed as a spring element. At this Design eliminates additional springs, so that the number of components reduced.
  • the invention continues proposed to cross the working surface of the strip-shaped grinding element its convex length. This results in a improved adaptation of the working surface of the grinding element to one of one Straight, different cutting edge geometry.
  • each Grinding element in parallel and at a distance from each other via one each Carrier resiliently guided on the housing.
  • Such a plurality of Grinding elements shortens that for grinding a cutting tool required time without the possibility of adjusting the individual To hinder grinding elements to the respective cutting edge geometry, since each Grinding element is guided resiliently on the housing independently of the others.
  • the work surfaces in cross section the serrated edge respective cutting edge of the cutting tool designed accordingly.
  • the spring-mounted grinding elements enable this cutting edge geometry too to move transversely to the longitudinal axis of the grinding elements.
  • the invention further proposes each strip-shaped Grinding element with its ends each on a tongue-shaped carrier to arrange and several tongue-shaped carriers to a carrier unit summarize, which can be used as a structural unit in the housing. hereby there is the possibility of an assembly comprising the grinding elements create that can be used in differently trained housing.
  • the carrier unit is non-rotatable on one Base plate arranged, each with guides for the free ends of the tongue-shaped carrier is provided in order to withstand even greater loads Abrasive elements to bend or otherwise damage them avoid.
  • the grinding elements between their on a tongue-shaped Carrier fixed ends be designed to be resilient.
  • the elastic properties of the tongue-shaped carriers result in elasticity of the grinding elements.
  • the elastic deformation of the grinding elements be limited by one stop each. This stop will preferably formed centrally on the carrier unit.
  • the invention results overall in a device for grinding Knives, scissors or similar cutting tools, despite their simple and inexpensive to manufacture a reliable grinding of Allows cutting tools, even if this one from a straight line have different cutting edge geometry.
  • the first embodiment shown in FIGS Grinding device comprises a housing 1 in which several strip-shaped Grinding elements 2 are arranged parallel and resiliently at a distance from one another.
  • Each grinding element 2 is arranged on a sheet-shaped carrier 3, which at Exemplary embodiment in each case at one end of the strip-shaped grinding element 2 is molded.
  • Each grinding element is supported by this sheet-shaped carrier 3 2 at its ends via a spring 4 on the housing 1.
  • this support takes place in a Housing 1 arranged inner part 1a.
  • To prevent the housing from slipping 1 To avoid during the grinding process is the housing 1 or its Inner part 1a provided with four feet 1b, which with a non-slip Footprint are provided.
  • FIGS. 5 and 6 show analogously to FIG. 3 when grinding a knife the grinding elements 2 each with a convex working surface due to their individual cushioning able to adapt to different, from adapting contours of the cutting edge geometry to a straight line.
  • the 5 shows the grinding of a knife blade with a concave cutting edge geometry, whereas a knife blade with a convex cutting edge geometry is shown in FIG. 6.
  • FIGS. 7 and 8 is the grinding of knife blades with a wavy Contour of the cutting edge is shown, using devices, which are described below.
  • Devices have the grinding elements 2 one of the waveform of the cutting edge adapted contour.
  • FIGS. 10 and 12 show a second embodiment of the device, which in turn comprises a housing 1 provided with feet 1b.
  • a carrier unit 5 is inserted by means of a base plate 6.
  • the at Embodiment forms three grinding elements 2 receiving carrier unit 5 together with the base plate 6, an assembly which according to FIGS. 10 and 12 can be used in differently designed housing 1 in a simple manner can.
  • FIGS. 13 to 15; 16a to 18c show their individual parts.
  • the work surface is convex is formed and which are bent at right angles at their ends. With these bent ends, the grinding elements 2 are in corresponding Recesses 5a of tongue-shaped carriers 5b used by a Go out middle piece 5c and thus form a support unit 5.
  • everyone tongue-shaped carrier 5b can be resilient due to its shape move towards the center piece 5c. It also results from the Arrangement of the grinding elements 2 on the tongue-shaped carriers 5b Carrier unit 5 an elastic spring possibility of each individual grinding element 2, as can be seen in particular from FIG. 13.
  • the center piece 5c of the carrier unit 5 is also included a stop bar 5d extending transversely to the grinding elements 2.
  • the entire carrier unit 5 is opened a base plate 6 arranged as an individual part in FIGS. 18a to 18c is shown.
  • the base plate 6 comprises a protruding from its top Hollow pin 6a, in which, according to FIG located pin 5e engages.
  • base plate 6 is on their ends with guide strips 6b, on which the free ends of the Carrier 5b are guided in the vertical direction, for this purpose with Guide grooves 5f are formed.
  • the base plate 6 finally has locking lugs 6c, with the aid of which the structural unit is inserted into a housing 1, as shown in FIGS. 9 and 11.
  • FIGS. 9 and 11 Through the Design of the structural unit described above, it is possible to use different housing 1, as shown by FIGS. 10 and 12 is pictured.
