Definitions

  • the invention enters a household press according to the preamble of claim 1.
  • DE 35 33 970 C2 describes a device for cracking or crushing of nuts, which is designed as a screw.
  • the two can halves are adjustable by means of two threaded connections against each other in the axial direction. One of these connections is formed by a movement thread with play in both the axial and radial directions. After inserting the nut into the opened can, the upper half of the can is screwed down to the nut by means of this thread. The further rotation to break the nut with this thread is not possible because of the required excessive force and therefore goes on the other threaded connection with a normal slope over. After the nut shell has been put in place, it is counterbalanced by tilting the can halves.
  • this household press is described in several variants, which consists of a large number of parts existing structure for all shown embodiments very complex. Since the upper half of the can is completely unscrewed from the lower one for inserting the nut, the use of this household press is very time consuming.
  • Advantageous compared to the above-cited embodiment according to DE 66 00 726 U has the effect here that when the nut shell is broken, the shell parts are chambered and can not fly around in an uncontrolled manner.
  • DE 36 24 733 C2 is shown in a further embodiment of the device according to DE 35 33 970 C2, as can be adjusted by one of the Do- senhdroitn locking means of the distance of the can halves to each other in adaptation to the size of the nuts to be crushed ,
  • DE 197 33 551 C2 shows a household press for cutting garlic with the following structure:
  • An outer, downwardly open housing carries in its lower part a transversely arranged cutting blade.
  • the upper housing closure is formed by a screw-on lid, which in turn carries an internal thread.
  • In the outer housing there is a rotatably mounted inner housing with a rectangular inner space and a arranged on the underside cutting grid, which acts together on rotation of the housing to each other with the cutting blade.
  • a rectangular die is accommodated, which is formed on its underside as a pressing part and represents the cooperating with the cutting grid counterpart. With this he forms the receiving space for the cutting material.
  • US 1 248 313 A describes a nutcracker. This consists of three parts, a nut part, a screw part and a base part.
  • the base part is a one-piece sheet metal part with a sleeve-like shaft, which merges into an open shell section, protruding from the end of a right-angled bottom.
  • the sleeve-shaped shaft of the base part has an axial slot open to the bottom, one edge of which is provided with teeth.
  • the female part is insertable into the shaft of the base part and has on the outside a raised portion with teeth which can be latched into the teeth of the shaft. For this purpose protrudes from the raised portion through the slot of the shaft through a pin.
  • the nut part By means of this pin, the nut part can be twisted so that its teeth are in engagement with the teeth of the shaft or not.
  • the female part has an internal thread into which the screw part can be screwed.
  • the screw member has at its bottom 5 of the base part facing the end of a plate. This plate, together with the bottom of the base part, defines a receiving space for a nut.
  • a knob is provided, with the help of the screw part can be rotated.
  • Nutcracker has the advantage that the screw part in adaptation to different nut sizes must not be screwed on a free path.
  • the nut member is first rotated so that its teeth are disengaged from the teeth of the shaft of the base member. Then, the screw part, without having to be rotated, be adjusted axially to the respective nut size. After concerns the plate of the screw on the surface of the nut, the nut part is again rotated so that its teeth engage the teeth of the shaft. Now, the nut part is fixed relative to the base part and by turning the screw part to an axial force can be exerted on the nut, which eventually leads to breakage of the nutshell.
  • the object of the present invention is to form a household press of the type mentioned so that the structure is simplistic, the handling is easy and time-saving and cleaning can be done easily.
  • the invention is characterized in that the household press in its basic form consists of only two parts, namely a screw and a nut.
  • the bottom of the nut forms a closed surface, so that the press in this basic form can preferably be used for breaking nuts.
  • the nut consists of a hollow cylinder with a bottom closed on one side and a half-shell-shaped part on the other side. This carries on its inner surface a trapezoidal thread, whose thread profile is inclined in the direction of the bottom, so that an undercut is formed on the flank facing the bottom of the thread.
  • the thread may fill the entire inner surface of the half-shell or be recessed in its longitudinal center region. With the resulting interruption of the thread is the
  • the screw consists of a threaded part with a subsequent handle in cylindrical form. It is preferably hollow, with a bottom at the end of the threaded part closes the hollow cylinder on one side.
  • the thread corresponds to that of the nut, the slope of the thread profile pointing in the other direction, ie an undercut is formed on the screw bottom remote from the flank of the thread.
  • the nut to be cracked is placed on the bottom of the nut and the screw is placed with its threaded part on the threaded part of the nut.
  • the screw slips over the slope of the thread profiles a piece in the direction of the side facing away from the bottom of the nut until it rests snugly in the nut thread.
  • the bottoms of screw and nut together with the nut's hollow cylinder now form a chamber enclosing the nut.
  • the two floors can be concave.
  • the screw bottom moves towards the nut and finally cracks, whereby the combing ensures that no shell parts can fly away when the nut is broken.
  • the screw Turn back to clearance with the head of the mother and then lift off from the mother.
  • the selected design of the thread ensures that the screw can not lift out of the nut during the cracking process:
  • the abutting surfaces of the undercuts generate under axial load a radial force component that holds the screw in the mother.
  • the attachment of a rotatable plate at the bottom of the screw has a positive effect in that the cutting material does not rotate when turning the screw and thus can be processed into pins, without these in their creation on the entrainment effect of the rotating screw bottom sheared off.
  • the respective floor is designed as a replacement part, which makes the household press to a true universal device.
  • the items of the household press whether plastic or metal, can be easily cleaned, for example, in the cutlery box of a dishwasher.
