description

The present invention relates to a corkscrew with Rack and levers.

We currently know corkscrews with four columns, which are made from consist of a spindle, which is in a four-column metal device is housed, the lower circular edge protected by a plastic ring, the attachment of the Allow corkscrews on the bottle neck while the upper parts of the frame converge until they have a guide form for the spindle. At the end of the spindle is attached the spiral which penetrates the cork while a rectangular plate inserted between the columns in the framework, which separates the spindle from the spiral and prevents the transmission of the rotary motion from the spindle to the spiral, the known mode of operation of the corkscrew guaranteed.

Such corkscrews have a high mechanical resistance, but work pretty slowly.

There are also corkscrews with levers that have a spindle and spiral are also built into a metallic construction, which also acts as a support on the bottle neck and serves as a guide for the spindle. Two levers are hinged to the upper edges of the scaffolding have teeth at their ends which fit into the thread gaps

the spindle engage. These levers are spread when the spiral penetrates the cork / while closing the lever transmits an upward movement to the spindle, which in this case acts as a rack exercises.

Such corkscrews allow the cork to be pulled out quickly, but are very prone to failure and break frequently, especially on the spindle. This is due to the fact that the levers are on the spindle in all stages of work press, because spindle and spiral are structural Reasons are not made in one piece, and because the clearance to be maintained between the teeth is often between the Lever and the spindle generated forces acting.

Another disadvantage that one often sees in conventional Corkscrews, consists in the unwanted detachment the plastic ring, which is simply pressed onto the inside of the edge of the framework and attached to the neck of the bottle will.

It is an object of the present invention to eliminate the aforementioned disadvantages of the conventional corkscrews by providing a device in which the progressive movement transmitted by the levers is separated from the rotational movement of the spindle.

The invention provides within the scope of the stated object

Realization of a device in front of which a grosoero Movement of the active element when pulling out nasty cork allows.

The invention still applies within the scope of the above-mentioned object The creation of an art at off ring 3 preferred not inadvertently can fall off the body of the corkscrew.

The task mentioned is carried out by the cork

zieher, which is mounted on a scaffold with hinged, with serrated levers is made and marked is by a rack, which can be moved in a guide carved out of the frame, as well as by an active element that has a handle at one end and terminates in a spiral at the other end, which is rotatably housed in a boring in the longitudinal direction through the rack bore. Preferably the frame is provided with a plastic ring underneath, the edge of which fits into a corresponding groove in the frame is clamped.

Other features and advantages of the invention will become clearer from the following description of a preferred embodiment of the corkscrew according to the invention with reference to FIG attached exemplary drawings. Show it:

disassembled state; 3 shows a longitudinal section of the rack; 4 shows a partial longitudinal section of the plastic ring and the part of the corkscrew to which the ring is connected.

With reference to FIGS. 1, 2 and 3, there is the one according to the invention Corkscrew from a frame 1, the two stands of the lower part 2 to be attached to the bottle neck with an upper part connect, v / elcher from the guide 3 in the form of a rectangular tube in which the rack 4 is displaceable is, as well as consists of the recordings in which the levers 5 are hinged.

The levers 5 are each provided with a toothed profile 6, which is present in corresponding, laterally on the rack 4 Depressions 7 engages.

A central bore runs through the rack 4 in the longitudinal direction and forms the central part of a one-piece Element 8 which ends in the spiral 9 and in a handle 10.

The element 8 can rotate freely in its receptacle; however, its displacement with respect to the rack 4 becomes prevented by a ring attached to the spiral 9 or a disk 11.

709885/0771

Along the outer walls of the two uprights of the frame 1 run two lateral grooves 12 for the at least partial accommodation of the completely un>: en rotated lever.

Analogously to this, the uppermost recess 13 of the rack 4 is enlarged, at least around the lever that is turned all the way up partially included.

The contact between the bottle neck and the lower part 2 of the frame 1 takes place via a plastic ring 14, which in particular is shown in FIG.

This ring is provided with a circular edge 15 which fits into a corresponding one in the interior of the lower part 2 of the frame 1 provided groove 16 is clamped.

The ring is also with an annular, εη the framework 1 abutting stop 17 so / ie provided with a protective rim 18.

The corkscrew works in the following way: To allow the spiral to penetrate the cork, the handle 10 and thereby the element 8 rotated. At this stage the rotary movement is completely independent of the Leverage because the levers only act on the rack.

To pull out the cork, the levers 5 must be quick

709885/0771

⁸ .. Ϊ732920

rotated downwards. The existing grooves in the uprights of the scaffolding 1 and in the rack enlarge the Rotational movement of the levers and consequently the displacement path of the rack. In this way it is guaranteed that the cork is pulled out with a single movement of the lever.

In practice it has been found that the device described above has the resistance and the long service life the four-column corkscrew combined with the fast operation of the lever-equipped corkscrew.

Further advantages not to be forgotten are:

- The greater stroke of the element that pulls out the cork, which ensures that the cork with a single movement can be pulled out;

- the elimination of clearances between the spindle and the levers provided with teeth, which often lead to malfunctions led;

the simple structure, thanks to which the device is also very economical to manufacture;

- the choice of materials and size of the various organs;

- the impossibility of inadvertent detachment of the plastic around.

Numerous changes can be made to the invention designed in this way.

The materials and dimensions can be as required to get voted.

In addition, all individual parts can be replaced by other, technically equivalent elements.
