ABSTRACT:
FIELD OF THE INVENTION
The present invention consists of a corkscrew, designed for the extraction of cork stoppers from bottles, which is manually operated with a lever-type extracting action.
BACKGROUND OF THE INVENTION
It is always necessary, in working with customers in all types of service in restaurants or refreshment establishments, to provide waiters and other staff with tools and utensils which, occupying minimum space, allow them to carry out specific tasks correctly and simply, as is the case with the clean extraction of cork stoppers, as indicated hereinbefore.
There are different types of corkscrews, which are already sufficiently well known and widely used. One of these types has a spike in the form of a ringlet that may be introduced by means of rotation into the stopper to be extracted, followed by an action in the stopper's direction of exit, which action is possible thanks to the lever arm to which the “ringlet” is attached. This action is completed by the provision of an adequate and sufficient point of support upon the edge of the mouth of the bottle itself, which has become the type of corkscrew already known, that is, the type that consists of a second class lever, with the resistance located in the middle area and the point of support at one end.
However, this type of corkscrew has the drawback that, in practice, when carrying out the extraction operation by raising the lever in the direction of exit of the stopper, the length of the arm from the point of support is insufficient to allow the whole stopper to be extracted, so that the operation has to be started again, introducing the “ringlet” further into the partly extracted stopper, which enables the support arm to finish the extraction.
SUMMARY OF THE INVENTION
The present invention is characterized essentially in that it features a multiple and graduated point of support. Consequently, the corkscrew that is the object of the present invention is designed to be able to extract a cork stopper that is forcefully and entirely introduced into the mouth of the bottle without breaking the stopper itself or the edges of the mouth of the bottle, both of which eventualities have an unfavorable influence on the serving of liquid contained in the bottle.
All of this is adequately resolved by applying a corkscrew with a graduated point of support, the object of the present utility model, which is equipped with a simple and easily operated mechanism that allows different points of support upon the mouth of the bottle to be used as the stopper is being extracted, so that it is not necessary to introduce the “ringlet” further into the stopper.
In order to be able to describe in every detail the features of the corkscrew that is the object of the present invention, this specification is accompanied by drawings in which, by way of a non-restrictive practical example, an embodiment of the corkscrew referred to is represented.
