Abstract

The invention concerns a version of the lever corkscrew also commonly known as "wine waiter", more particularly the functioning of the lever (1) and the grooved (5) fulcrum (2) comprising the oil-drop-shaped notches and which are urged to rest on the bottleneck edge for extracting the cork. The invention concerns a modified version of the lever corkscrew and in particular the element which is urged to rest on the bottleneck edge specially designed to enable the cork stopper closing the bottle to be rapidly, gradually and completely extracted.

Description

 MULTIPLE SUPPORT CORKSCREW

The present invention relates to a variant of the corkscrew of the lever type, also commonly called sommelier. The invention relates more particularly to the operation of the lever 1 and of the fulcrum element 2 with grooves 5 which includes notches 7 in the form of a drop of oil and which comes to bear on the edge of the neck of the bottle to allow the extraction of the plug and the location of the hinge pin 8 of the twist rod 9 which is closer to the hinge pin 6 of said support element, so as to allow a more vertical and rectilinear displacement of the twist rod 9 during the extraction of the cork stopper.

The present invention relates to a modification of the lever corkscrew and bearing on the element which comes to rest on the rim of the neck of the bottle, specially designed to allow rapid, gradual and complete extraction of the cork stopper closing a bottle. .

Lever corkscrews currently known and commonly used, base their operation on a lever movement in which the fulcrum located at one of its ends is disposed on the edge of the neck of the bottle, the resistance to overcome, located in the central area, is constituted by the cork to be extracted and the shape applied to the other end of the lever 1 is exerted by the wrist of the user.

Although very widely used, these corkscrews have the drawback of not being able to extract the cork in a single operation because of the length of the cork and the limited stroke of the corkscrew lever, which often means that the operation must be resumed. by reintroducing the twist rod more deeply and repeating the extraction movement, which has the consequence of splitting or breaking the plug and the consequences which follow.

The present invention aims to remedy these drawbacks in particular: by reducing the tensile force and therefore relates to a corkscrew comprising a fulcrum element provided with multiple notches in the form of a drop of oil which allows extraction of the longest plugs without having to reintroduce the twist rod inside the plug by increasing the stroke of the twist with the second or third press. The object of the invention is also to place the axis 8 of the twist rod closer to the axis 6 along which the element of grooved support point slides, so that the removal of the plug is done by a more vertical movement.

Indeed, the corkscrew of the lever type, equipped with the support element with grooves and with multiple notches and a rod with an articulated twist, is remarkable according to the invention in that it comprises notches located at several levels on the fulcrum element, which allows the axis 6 of the action lever 1 to be placed at different levels so as to allow a greater elevation margin for the extraction of the plug as well as a more vertical displacement of the twist rod. The originality of the invention is based on the possibility of sliding the support element with grooves and notches around and along the axis 6 located at the end of the lever 1. Indeed, on the pulls -corks currently known, the fulcrum which comes to be placed on the rim of the neck of the bottle can only initiate a rotational movement with the arm of the lever to which it is attached for an axis; in our invention the support element can not only perform a rotational movement but it can slide freely vertically and thus modify its intervention height to allow the extraction of the longest plugs.

The appended figures will make it easy to understand the novelty of the invented system as well as the manner of its operation. In these figures, identical references designate similar elements.

Figure 1 shows a slightly three-quarter side view of the corkscrew to show the invention with these different elements deployed.

Figure 2 shows by arrows how the support element allows by sliding to position the axis 6 located at the end of the lever 1 at different levels of use by engaging it in the oil drop notches 7 located along the two grooves 5 of the fulcrum element 2 Figure 1.

Figure 3 shows the corkscrew before the start of the extraction operation when the twist rod is fully inserted into the stopper. The axis 6 of the lever 1 is then positioned in the first notch. Figure 4 shows the position occupied by the corkscrew until the maximum travel of the fulcrum element.

Figure 5 shows the next position when the cap is already partially out of the neck of the bottle and the establishment of the axis 6 in the second notch to start the next extraction phase. The third notch can then be used in the same way as previously for very long type plugs.

Figure 6 for the rest, shows that the corkscrew of the present invention comprises in this embodiment a handle or lever 1 which comprises at the upper end a notch 10 for the operation intended to remove the crown caps and a auxiliary knife 11; usual auxiliary essential for the operation intended to remove the overcapping cap set on the neck or neck of the bottle to be uncorked.

Figure 1, in the central front part of the lever 1 is located the twist rod 9 pivoting about a hinge pin 8. In addition, on the part located on the front end is placed a fixed axis 6 on which can slide the fulcrum element 2 to allow the elevation level to be varied by engaging the fixed axis 6 in one of the different notches located on the two cheeks 3 of the point element support.

The fulcrum element 2 with grooves has a bottom 4 (or a back) and two side cheeks 3 which gives it the appearance of a "U" shaped iron; parallel cheeks in which two grooves 5 were provided with notches 7 Figure 1. The fulcrum element is moreover provided with a staircase rim 13 which allows it to be pressed on the neck of the bottle 14 as the drawing indicates in Figures 3, 4 and 5.

In this way, the corkscrew is ready to act as shown in Figures 3, 4 and 5 by exerting for this a force directed upwards by the intermediary of the lever 1 which carries with it the spin 9 and at the same time causes time for the start of the exit of the cork from the neck.

This arrangement makes it possible to then extract the stopper (Figures 3, 4 and 5) in several phases according to its sinking and its size out of the bottle and this without having to reintroduce the twist rod in the stopper.

It is thus possible to obtain a maximum continuous displacement as can be seen in Figures 4 and 5, which the standard type corkscrew cannot do. By providing the articulation axis 8 of the twist rod 9 Figure 1 closer to the axis 6, the displacement of the twist rod rises almost vertically so that the plug 15 (Figures 4 and 5) does not undergoes little or no offset traction effort, thereby eliminating the risk of torsional breakage thereof. This modification of the fulcrum element 2 Figure 1 of the present invention allows rapid and efficient use of the fact that the extraction operation is carried out successively in two or three positions of the axis 6 Figure 1 which is housed in the droplets of oil 7 of the fulcrum element by simple push.

The invention of this new type of fulcrum element allows it to be adapted to the lever corkscrew which is commercially available and which has flat shapes and reduced dimensions as required by the lever corkscrews. and which allow the user to carry it in a pocket in a practical manner as is the case of the most frequent users such as waiters, bar waiters or sommeliers.
