Definitions

  • the present invention relates to corkscrews fitted with means making it possible to reduce the effort and the extraction time of bottle stoppers or similar containers to a considerable extent.
  • corkscrew The object of this corkscrew is to overcome these various drawbacks while offering a very simple and very fast use.
  • the invention as characterized in the claims solves the problem of creating a hoist reduction corkscrew very simple to manufacture and assemble, designed according to three versions of increasing simplicity.
  • the first version according to the invention simplifies the corkscrew described in the French patent, and in particular the design of the operating handle and the mounting.
  • the second version differs from the first in that the stirrup receiving the return springs is a single central rod and not a U, so the design of the mittens is simpler and the operating cable is much easier to install .
  • the lower block moves with a stroke equal to that of the extraction, while the upper block is fixed.
  • the operating handle integral with the external telescopic tube moves with it, driving the traction belt of the lower block.
  • the third version is even simpler than the previous two in that the telescopic tubes are replaced by a tubular body in the bottom of which is fixed the upper block which remains stationary.
  • the mittens and the tubular body are made of molded plastic, which eliminates many machining operations and reduces assembly to almost nothing.
  • the first embodiment shown in Figures 1 and 2 comprises a main tube 1 flared at its base to serve as a guide and support on the neck of the bottles to be opened.
  • This tube is shouldered in 2 so as to constitute an extraction end-of-travel stop.
  • the second part of the tube also has a shoulder 3 which serves as an internal support for the body of the upper block 4 secured to said shoulder by means of the washer 5 by means of the rivet 6 or by any other known means.
  • a second muffle 7 is arranged at the base, fixed to the guide plate 8 by means of crimps 10, 11, 12, 13, from the lower part of the rods of the stirrup metal 9 folded into a U shape and counter-folded at its upper part 14 to allow the rivet 6 to be put in place.
  • the guide plate or tendril plate 8 receives the tendril 15 welded or crimped.
  • Each of the mittens 4, 7 has two flat pulleys 16,17, the innermost pulleys 17 are of a smaller diameter to ensure the passage of the drive belt towards the second stage of pulleys 16.
  • the pulleys rotate on the axes shoulders 18 which are crimped on the block bodies made of folded sheet.
  • the belt 19, made of metal of very small thickness or of flexible plastic material of low elongation under load, comprises, at each of its ends, a loop obtained by gluing or by pinching by means of a crimped metal clip 20, or else by welding for the metal strap.
  • the lower loop is passed in the shouldered axis 21, itself engaged in the groove 22.
  • the upper loop is slid in the same way on the axis 23 engaged in a groove 24 of the operating handle 25.
  • the handle 25 is produced by molding.
  • the mittens are resiliently returned to the rest position by two compression return springs 26,27, slid over the branches 9 of the guide bracket of the lower muffle.
  • the upper part of the stirrup is guided by the washer 5.
  • Three telescopic extension tubes 28, 29, 30 slide over each other to keep the handle 25 in the axis of the main tube 1 during the extraction of the plug. They are flared at their upper end and narrowed at the base to avoid their dislocation during sliding.
  • the different tubes have received four longitudinal stampings 31, 32, 33, 34, avoiding the twisting of the tubes.
  • the washer 8 has the clearances corresponding to the grooves stamped in the body 1 so as to be immobilized in rotation.
  • the handle 25 is fitted into the free end of the outer tube 30, its two rods are engaged in the opposite grooves 35, 36 of the tube 30 to ensure the drive in rotation.
  • the handle is either glued to the tube 30, or else the tube 30 is crimped onto the handle so that it can be pulled without risking to dislodge it.
  • the handle 25 is pulled, a pull is exerted on the belt, the tubes slide one on the other, the corkscrew lengthens, the swivel washer 8 sinks into the body 1 until coming into abutment on the shoulder 2 at the end of extraction of the plug.
  • the handle is then released and the return springs bring the lower block back to the low position for a new extraction.
  • the outer extension tube 30, under the action of the springs 26, 27, is in abutment on the shoulder of the tube 1.
  • the reduction ratio obtained by the hoist is a function of the number of stages of pulleys and of their diameter.
  • Figure 3 shows the top view of the corkscrew, handle and extension tubes removed. We see the clearance 37 formed on the upper block 4 and on the shoulder 3 of the main tube 1 to ensure the passage of the belt towards the axis 23 of the handle 25, as well as the shape of the longitudinal stamps transmitting the torque from the handle to the spin.
  • Figure 4 shows, in top view, the washer 5 ensuring, in cooperation with the blind rivet 6, the fixing of the upper block 4 on the shoulder 3 of the body 1, the hole 38 for passage of the blind rivet 6 and the grooves 39.40, from stirrup passage 9.
  • FIGS 5 and 6 show a second version of corkscrew arranged in the same telescopic tubular assembly.
  • the design of the hoist is different. It comprises a lower block 41 made of folded sheet metal, secured to the plate 42 tendril holder by two rivets 43.
  • the block 41 forms a yoke on which are mounted, on each side in cantilever, pulleys with identical grooves 44 , 45.
  • the stirrup is replaced by a central guide rod 46 carrying the return spring 47 intended to bring the gimbal plate back into the rest position.
  • the guide rod 46 passes through the upper block 48, identical to the lower block, and is engaged in a central hole in the washer 49 for fixing the upper block on the end 3 of the tube 1 by means of blind rivets 6 as on the first version.
  • the pulleys 44,45 are mounted rotating freely on the axes 50,51, crimped on the yoke.
  • the strap is replaced by a flexible cable which may be made of stranded steel, or of plastic material of the fishing wire or braided cord type having a high resistance to elongation.
  • the lower part is engaged in the washer 42 stopped by the bulge 52 obtained by overmolding or by a crimped staple or by any other known means.
  • Figure 7 shows the shape of the washer 49 for fixing the upper bearing on the shoulder of the tube 1.
  • the slot 53 allows the passage of the cable to its point of attachment on the axis 23.
  • the holes 54 receive the blind rivets 6 ensuring immobilization on the tube 1.
  • Figure 8 is a section along arrow 55 ( Figure 5) showing the dis,; position of the upper block in the narrowed part of the tube 1, as well as the location of the pulleys 44,45.
  • the third version of corkscrew according to the invention comprises a tubular body 61 which can be provided, outside, with means, polygonal sides, longitudinal grooves or the like, for ensure good manual holding of the tube for screwing because it is not necessary to use a handle as in previous versions since there is no pull on a telescopic tube.
  • the lower part 62 is flared for centering on the upper part of the neck of the bottles at the end of screwing.
  • the telescopic tubes have been eliminated, the internal friction is therefore very reduced. Reeving is also simplified; it consists of the upper block 63 and the lower block 64 both obtained from injection molded plastic.
  • the tubular body can be molded from light metal or also from plastic. All machining is eliminated except the swivel plate 66 and the pulley axes.
  • the tubular body 61 has 4 grooves 65 serving as guidance and anti-rotation to the lower block 64 as well as to the plate 66 carrying the swirler 67 crimped or welded.
  • the lower block 64 is secured to the tendril plate by the crimps 67, 68 of the stirrup 69, the crimps are executed during assembly of the mittens.
  • the stirrup 69 serves as a guide for the two return springs 70,71, it passes through the upper block through the holes 72,73, and the lower block through the holes 74,75, these holes are cut over most of their length to ensure support and passage of return springs 70.71.
  • the pitch between the stirrup rods can be increased
  • the pins 80 can be free in their housing because they are held in place by the springs 70, 71. We can also leave them free in their housing, but put them slightly hard in the pulleys or vice versa.
  • the crimps 68 are made after the stirrup has been placed in the block 63 and the springs 70, 71.
  • the muffle 64 and the plate 66 are then placed and the crimping 67 is carried out.
  • the entire hoist is then engaged in the body 61.
  • the upper muffle 63 is brought into abutment at the bottom of the tubular body 61 and is immobilized by a pin 82 crossing across the body 61 and the muffle 63. We could also glue the muffle.
  • Figure 10 shows in section along B of Fig.11 the arrangement of the hoist.
  • the cord 81 hooked on the axis 80 passes successively on the pulleys 79,77,78,76, and leaves the tubular body 61 by the groove 83 (fig.14) and by the hole 84 (fig.ll) to hang along the body 61 under the weight of the ring 85 on which it is fixed.
  • FIG. 10 a variant of FIG. 9 shows a bush 86 of molded plastic, sliding on the lower end of the body 61 and capable of being clipped elastically in the grooves 87, 88, of the body 61.
  • This socket has the function of centering the corkscrew on the bottle.
  • the sleeve 86 is pushed down until it clips elastically into the groove 88 of the body. Then place the flared part of the sleeve on top of the neck of the bottle, then push the upper end of the tubular body, the sleeve unclips and rises slightly until the tip of the spin touches the cap on which it is then centered.
  • the sleeve 86 is then completely reassembled on the body 61 and can be clipped into the groove 87. All that remains is to pull on the ring 85 to extract the plug.
  • the lower block goes up in the body 61 until it comes into abutment on the upper block 63 at the end of extraction, while the stirrup 69 has come out of the body 61 through the hole 84 (shown in fine dotted lines in FIG. 9) .
  • the return springs 70, 71 bring the lower block 64 back into the down position until the upper part of the stirrup abuts on top of the block 63 .
