Definitions

  • ABSTRACT A hand-operated slicing cutter mechanism wherein a flexible cutting blade is clampingly mounted at its ends in spanned condition at support means which, in turn, are displaceably mounted at an impact element possessing an impact surface intended to bear against the material to be cut, for the purpose of changing the [30] 1 Foreign i a Priority Data spacing between'the cutting blade and the impact sur- Mar. 1, 1971 Germany ..o 71 07 546.2 face. According'to important asp t f the invention,
  • the support means consists of the legs of a rigid sub- [52] US. Cl. ..30/283 stantially U-shaped support element at which there is [51 Int. Cl. ..B26b 3/03 guided the impact element in a direction which is [58] Field Of Search JO/283,284,304 disposed perpendicular to the plane of the cutting blade and the impact surface.
  • This device is considered to be surely practically hardly usable, firstly because of the absence of any blade clamp ing or spanning mechanism, secondly because of the unsuitability of the spacing adjustment mechanism.
  • This unsuitablility is deemed to be predicated upon the fact that in all probability, during the adjustment operation, the slides bind in their guide grooves, thereby also destroying the parallelism of the cutting blade with regard to the impact surface.
  • a primary objective of the present invention is to provide a new and improved construction of handoperated slicing cutter mechanism which effectively and reliably fulfills the existing need in the art and is not associated with the aforementiond drawbacks and limitations of the prior art constructions.
  • Still a further significant object of the present invention relates to a new and improved construction of hand-operated slicing cutter mechanism which does not exhibit the drawbacks of the above-discussed prior art constructions, can be fabricated at relatively low cost, can be easily and dexterously used by even unskilled individuals, and wherein adjustment of the spacing between the cutting blade and the impact surface can be quite easily carried out.
  • the last-mentioned objective is particularly difficult to solve since there must be taken into account an irregular friction of the support means at its guides.
  • the impact element for reasons of cost and for the purpose of reducing weight, should be fabricated as an injection moldedpart or component, then one must take into account less deformation during changing of the clamping action at the cutting blade. Thus it is not possible to rely upon an exact guiding without play of the support means.
  • the inventive cutting mechanism is manifested by the features that the supportmeans consists of the legs of a rigid substantially U-shaped support element at which there is guided the impact element in a direction perpendicular to the plane of the cutting knife and the cutting surface. Further, there is rotatably mounted at one of both elements an adjustment shaft which is parallel to the cut ting knife and which is provided at the region of the legs with similar pinion teeth which mesh with gear rack teeth provided at the other of both elements.
  • one of both support element legs, in which the adjustment shaft is mounted is provided with an opening at the region of such adjustment shaft through which extends a handwheel which is fixedly seated upon the adjustment shaft.
  • This construction affords increased handiness or manipulation possibility of the slicing cutter and renders possible a pleasing constructional form, something which is extremely significant from the commercial standpoint.
  • FIG. 1 is a top plan view of the slicing cutting mechanism designed according to the invention
  • FIG. 2 is a cross-sectional view of the cutting mechanism or slicing cutter depicted in FIG. 1, taken substantially along the line IIII thereof;
  • FIG. 3 is a cross-sectional view of the cutting mechanism depicted in FIG. 1, taken substantially along the line III-III thereof;
  • FIG. 4 is a cross-sectional view of the cutting mechanism depicted in FIG. 1, taken substantially along the line IV-IV thereof.
  • the slicing cutting mechanism constructed as a hand-operated cutter instrument and depicted in the drawing, will be seen to embody a rigid support or carrier element 1 which in plan view possesses a substantially U-shaped configuration and an impact or contact element 2.
  • Each of these elements 1 and 2 are advantageously fabricated as injection molded plastic parts.
  • a flexible cutting blade or knife 3 can be clamped or spanned at the legs 1a and 1b of the support element 1.
  • the cutting blade 3 is introduced from below into a slot of the leg wall at which bears a bolt member 4 which is fixedly riveted or otherwise suitably secured to such blade end.
  • the other blade end is attached by means of a pin 5 at a square portion 6a of a clamping or tensioning bolt 6 which is guided in a suitable hole or aperture of the leg 1b and the screw-formed part 6b of which carries a tightening or clamping nut 7, the thickened freely exposed portion of which is knurled at its periphery.
  • a respective groove lf which is disposed at right angles to the plane of the cutting blade 3. Tongue members 2a are displaceably guided in such grooves If.
  • tongue members are provided at the ends of that part or portion 2b of the impact element 2 diposed at right angles to the plane of the cutting blade 3, and while part 2b for the most part is flat or planar.
  • the part 2b is, however, profiled at approximately the central third of its length in such a manner that it forms a gripping trough or groove for the other fingers of the hand holding the cutter as best seen by referring to FIG. 4.
  • the part 2c extending over the entire length of the impact element 2 possesses the impact or contact surface 8 extending parallel to the cutting blade 3 and intended to bear against the material to be cut.
  • an adjustment shaft 9 which extends substantially parallel to the cutting blade 3.
  • the end portions 9a of this adjustment shaft 9 are formed as identical or similar pinions which mesh with identical or similar gear rack teeth 2d, the rack teeth of which protrude out of the upper surface of the impact element portion 2b, as such has been best shown by referring to FIG. 2. It should be observed that neither the pinion teeth of the shaft end portions 9a nor the gear rack teeth 2d possess an offset or displaced portion. Additionally, it is to be observed that the pinion teeth cooperate without play with the gear rack teeth.
  • the mechanism embodying the adjustment shaft 9 and the teeth 2d should insure that in each adjusted position the impact surface 8 is perfectly parallel with regard to the cutting blade 3, because otherwise binding can occur during the cutting operation which, as experience has shown, can be very much of a hindrance.
  • the parallel guiding rendered possible by the just-considered mechanism also enables the provision of a sufficient amount of play between the end surfaces of the tongues 2a and the oppositely situated floor surfaces of the guide grooves lfand likewise between the end surfaces of the impact element and the oppositely situated transverse walls 1c and 1d of the support element 1, which play can possibly change during change of clamping or spanning action exerted at the cutting knife or blade.
  • the part 2b of the impact or contact element 2 is provided at its upper face with two rows of pawl or looking recesses 10 adjacent the teeth 2d, and with which recesses 10 cooperate resilient locking or rachet elements 11 for arresting the displacement of the support element 1 with regard to the impact element 2.
  • These locking or rachet elements 11, formed for instance of plastic, may advantageously possess the nose-like configuration depicted in FIG. 3 and are fixedly retained by means of one of their legs at the bifurcated eyes or eyelets 1e formed at the support element 1.
  • the support element leg lb is provided at its upper wall with an opening 12 out of which protrudes an adjustment handwheel 13 pressed onto or otherwise suitably connected with the there located end portion 9a of the adjustment shaft 9. Since the justmentioned handwheel l3 possesses very little lateral play in the opening 12, the axial mobility of the adjustment shaft 9 is correspondingly limited.
  • the handwheel 13 is provided with knurls or serrations at one-half of its width, the remaining outer surface carries a scale 14 which in coaction with an index line 15 provided at the support element 1 indicates the magnitude of the spacing between the cutting blade 3 and the confronting impact surface 8.
  • a hand-operated slicing cutting mechanism comprising support means, a flexible cutting blade clamped at its ends at said support means, an impact element possessing an impact surface intended to bear against the material to be cut, said support means being displaceably mounted at said impact element for the purpose of changing the spacing between the cutting blade and said impact surface, said support means comprising a rigid substantially U-shaped support element having leg members, said impact element being guided at said U-shaped support element in a direction perpendicular to the plane of said cutting blade and the impact surface, an adjustment shaft rotatably mounted at one of said elements and disposed substantially parallel to the cutting blade, said adjustment shaft being provided shaft and protruding out of said opening.
