Definitions

  • the invention relates to a device for comminuting food, such as onions and the like, with a housing which can be slipped over the material to be comminuted and a knife which can be moved downwards by means of a plunger against the force of a spring, the knife during the upward movement is inevitably rotated by an angle through the guide in the housing.
  • a crushing device of this type is e.g. Known from German Patent No. 2719980, the rotation of the knife is achieved in that the plunger is surrounded by a wrap spring, which non-positively encloses it during the upward movement, while it is widened during the downward movement and does not cause any inevitable rotation.
  • the known shredding devices have a number of disadvantages, one of which is that the function of the wrap spring is not always reliable and, depending on the cleaning and keeping the device clean, can get stuck on the pestle instead of releasing it. For this reason, improvements to the dismantling have been proposed several times so that the complicated mechanism is more accessible and can be cleaned.
  • the present invention has for its object to propose a novel clutch with which an inevitable indexing of the knife is achieved.
  • this is achieved by a coupling of two concentrically arranged, essentially annular elements, of which one element on the end face facing the second element has a number of teeth tapered on one side over the circumference, while the second part on the one facing the first Front surface has at least two or more resilient pawl and engaging in the vertical flank of the teeth, the first coupling part sliding in spirally guided grooves of the housing, while the second coupling part is firmly connected to the actuating mechanism.
  • the device has a housing 1, which consists of an upper part 2 and a lower part 3.
  • the lower part is connected to the upper part by means of a bayonet catch or the like.
  • the upper housing part 2 has a chamber which is open at the top and which is formed by a cylindrical wall 4 and a base 5 which are integrally connected to the outer wall of the housing.
  • the bottom 5 has an opening 7 surrounded by a cylindrical projection 6.
  • the cylindrical wall On its inner surface, the cylindrical wall has spirally guided grooves 8, which can be seen in FIG. 4.
  • the chamber formed from the cylindrical wall 4 serves to receive the actuating mechanism 9.
  • the actuating mechanism consists of a plunger 11 which is guided in the opening of the chamber floor.
  • the plunger 11 is firmly connected to a push button 12 which has a cylindrical extension 13 downwards, the outer diameter of which corresponds to the inner diameter of the chamber. The push button is thus guided in the chamber.
  • a knife holder is attached to the lower end of the ram.
  • a shock absorber 18 is located between the knife holder 17 and the chamber bottom.
  • a wavy-shaped cleaver 19 known per se is fastened in the knife holder.
  • a wiper 21 is provided in a manner known per se, which can also be removed when the housing is disassembled into the upper part and lower part. Finally, on the lower side of the lower housing part 3 there is a chopping plate 22 on which the housing is placed.
  • the coupling consists of two parts 15, 16, which, however, are joined together and can be rotated relative to one another, but only in one direction.
  • the first part 15 is shown in FIG. 2, specifically a side view in section 2a and a top view in FIG. 2b.
  • the first coupling part 15 a flat disk 23 which is provided on its upper side with teeth 24 which are beveled on one side and have steep flanks on the other side. 16 teeth are distributed over the circumference of the disk 23, so that each tooth corresponds to an angle of 22.5 degrees.
  • the disk On its outer periphery, the disk has a cylindrical extension 25 which is provided with four cylindrical cams 26 which are offset by 90 degrees. The diameter of these cams is 3.5 mm and thus corresponds to the width of the spiral grooves 8 in the chamber wall.
  • the disk 23 On its inside, the disk 23 carries a long, upwardly directed cylindrical projection 27, the inside diameter of which is larger than the outside diameter of the plunger 11.
  • the projection 27 has on its upper side an upwardly conically widened widening 28 which forms a stop at the bottom , with the help of which the two coupling parts are held together.
  • the height of the cylindrical extension 27 corresponds to the height of the second part of the coupling to be described below.
  • FIG. 3 shows a combination of section and view and FIG. 3b shows a floor plan.
  • FIG. 3a shows a combination of section and view
  • FIG. 3b shows a floor plan.
  • the section shown in FIG. 3a does not is guided straight, but runs in part arcuate.
  • the section line is drawn in dash-dot lines in FIG. 3b.
  • the second coupling element 16 essentially consists of a cylindrical outer wall 29 which is provided with two axially parallel projections 31 lying opposite one another. These projections 31 are used to insert the second coupling part 16 into corresponding grooves 30 in the inner wall of the extension of the push button 12.
  • Parts of a base 32 are connected in one piece to the cylindrical wall 29, and these parts extend opposite one another in each case over 90 ° .
  • On these base parts there are in turn upwardly directed lugs 33, also comprising an angle of 90 ° , the height of which corresponds to the lug of the first element until the widening stops.
  • the distance between these two quarter-cylindrical projections 33 corresponds to the outside diameter of the projection of the first element.
  • the function of the clutch is as follows.
  • the push button When the push button is pressed down by hand, the lower part of the coupling is rotated by the spiral grooves.
  • the push button since the push button is held by the operating hand and cannot rotate, the upper coupling part with the tongues slides over the inclined surfaces of the teeth.
  • the engagement of the tongues in the steep flanks of the teeth means that the two coupling parts can no longer rotate relative to one another.
  • the button, the plunger and thus the knife are also rotated.
  • Each twist is 22.5 degrees, after sixteen operations an entire turn is achieved.
  • the usual plastic materials come into question as material for the device.
  • the coupling is preferably made of polyoxymethylene (Delrin (R)).
  • Delrin (R) polyoxymethylene
  • other abrasion-resistant materials with the necessary elastic properties are suitable.
