Definitions

  • the present invention relates to a corkscrew with screwing, extraction and automatic expulsion of corks for bottles.
  • the present invention refers to a corkscrew of the type provided with a thread which is inserted into the cork automatically by means of a vertical translation of a thread-bearing bar.
  • corkscrew is placed on the rim of the bottle neck without foreseeing a blockage between the rim of the bottle neck and the corkscrew, and so, particular attention has to be paid in the phase of insertion of the thread into the cork, and a very strong pressure has to be made on to the corkscrew itself.
  • DE-A-355971 discloses a corkscrew comprising a framework provided with guides for the sliding of a mobile carriage, and a corkscrew thread to be embedded in a cork and connected to a plate.
  • the lever has to be pushed up again to extract the cork from the bottle.
  • Said device like the other devices of the prior art, is not able to an automatic extraction of the cork from the corkscrew thread.
  • the aim of the present invention is to eliminate the above mentioned drawbacks and in particular to be able to carry out both the screwing, the extraction and the expulsion of the thread into the cork and from the cork, automatically, by means of a simple translating operation of a thread-bearing bar.
  • a further aim of the present invention is to make stable, and without operating difficulties, both the introduction of the thread into the cork and the extraction of the thread from the cork.
  • two levers 6 and 7 are pivoted, said two levers bearing two cog wheels 8 and 9, said cog wheels engaging to a toothed, hollow shaft 10 sliding within a hole 11 which passes through the mobile carriage and inside the crosspiece 5.
  • the levers 6 and 7 are maintained in position by two external plates 6a and 7a which are screwed in correspondence with the axis of rotation of the two cog wheels 8 and 9.
  • the toothed, hollow shaft 10 shows a coaxial cavity 12 inside which a thread 13 can slide, said thread being able to rotate about a pin 14, constrained to a plate 16, sliding within slits 15 (as shown in figures 6 and 7) obtained in said toothed, hollow shaft.
  • a spring 17 is inserted between the plate 16 and the mobile carriage, while another spring 18 is inserted into the cavity 12, said spring connecting the plate 16 to the bottom of the toothed, hollow shaft in such a way so as to maintain the thread 13 pulled towards the top inside said cavity.
  • a cap 19 is inserted at the bottom of the guide bars which is free to slide along said guide bars, said cap comprising a disk 19a provided with a through hole 19b, which has a diameter slightly higher than that of the external diameter of the thread, having a bar or a helical guide 20, which forces the thread to rotate when said thread is vertically translated, as will be described in the following description.
  • the disk 19a comprises two bars 19d sliding vertically inside grooves obtained in a cylindrical body 19c.
  • the cylindrical body 19c is provided with longitudinal grooves within which are inserted the ends of the guide bars, which in said part are close to each other, and the bars of the cap as shown in figure 8.
  • the lateral surface of said cylindrical body has two slits 21 through which are inserted two flat springs 23 shaped in such a way that they can be inserted under the rim of the neck 24 of the bottle 25 so as to hold the bottle during the thread screwing phase.
  • the flat springs 23 are pivoted in 22 and are pressed by springs 26 towards the neck of the bottle, said springs showing a portion outside the cylindrical body on which it is possible to act by pressing using one's fingers so as to unhook the bottle.
  • a housing 27 into which is inserted a block 28 which is subject to a slight horizontal oscillation.
  • the block 28 is provided with a slot 29 through which the toothed hollow shaft 10 passes.
  • the block 28 also bears an upper fork 30 to be inserted between the teeth of the toothed, hollow shaft, and a lower fork 31 to be inserted into a notch 32 obtained in the mobile carriage.
  • a projection 33 having the shape of an inclined plane is provided in correspondence with the upper fork, which projection 33 acts on the upper fork, and vice versa, on the carriage 4 is provided a projection 34 having the shape of an inclined plane, which projection 34 acts on an inclined plane 35 which is obtained on the block 28.
  • the block 28, the forks 30 and 31, the projections 33 and 34 are means for carrying out the constraining between the toothed, hollow shaft and the crosspiece or between the mobile carriage and the crosspiece.
  • the corkscrew is positioned on the top of the bottle with the two levers 6 and 7 raised, as shown in figure 1) thanks to the spring 17 which maintains the mobile carriage pushed upwards.
  • the upper fork 30 is inserted in one of the external cavities of the shaft 10 and so said shaft 10 is constrained to the crosspiece 5 of the framework, while the mobile carriage 4 is free to translate towards the bottom.
  • the neck of the bottle is inserted into the cap 19 as far as the rim of the bottle neck is held back by the two flat springs, said springs opening in the introduction phase and closing under the rim of the bottle neck.
  • the thread 13 will start to come out of the cavity 12 and at the same time will be forced to rotate by the bar or helical guide 20, thus beginning the penetration into the cork.
  • the tooth 34 constrained to the mobile carriage will move the block 28 towards the left in such a way so as to carry out the release of the fork 30 and the hooking up of the lower fork in the seat 32 in such a way that the mobile carriage remains hooked to the crosspiece 5 and the toothed hollow shaft is free to vertically translate upwards when a second rotation of the levers 6 and 7 towards the bottom begins.
  • the cork is left inside the corkscrew and can be removed manually.
  • the cap 19 returns to its initial housing while the toothed, hollow shaft 10 returns towards the bottom pushed by the spring 17, and with the thread recalled by the spring 18 in the cavity 12.
  • the shaft 10 during the final phase of descent, strikes with the inclined plane 33 against the block 28 moving it towards the right, thus inserting the fork into the cavity of the shaft while the mobile carriage is freed from the fork 32.
  • the present invention can be susceptible to numerous variations or changes, for example the constraining means of the toothed, hollow shaft 10, and the mobile carriage 4 at the crosspiece 5 can be made in a different way, without falling outside the field of the following claims.
