Object of the Invention
[0001] The present invention refers to an improved portable cork-screw, contributing basically
novel features and important advantages with respect to similar devices known and
used for the same purpose in the present state of the art.
[0002] More specifically, the invention proposes the development of a device that may be
used as a cork-screw, with a sufficiently reduced size to be able to be carried by
the user, making it possible to perform, comfortably and simply, the removal of a
bottle cork with a minimum effort and applicable to any type of stopper, independently
from its characteristics or size by a single operation, or in two stages depending
on the length of the cork in question. Moreover, the design of the cork-screw has
been conceived in such a way that it also provides, in the same body, means to cut
the capsules that may cover the cork itself.
[0003] The field of application of the invention is in the industry dedicated to the manufacture
of household items, gifts, promotion and similar items, as well as for industrial
and domestic use.
Background and Summary of the Invention
[0004] Several devices that may be used as cork-screws are known in the state of the art,
with structural designs and
[0005] Several devices that may be used as cork-screws are known in the state of the art,
with structural designs and widely varied shapes. Generally, all these devices are
provided with a suitable spiral component to be "screwed" in the bottle cork to be
removed and at least, a handle component by which the user applies the pulling effort
during the cork removal operation.
[0006] In the case of portable cork-screws, that is, those that may be easily carried by
the user in a pocket, it is logical that the size is reduced to a maximum, trying
to maintain, as far as possible, the advantages of comfort and easy use as others
of a greater size. On many occasions this situation leads to the adoption of complicated
solutions giving structurally complex devices with a difficult design.
[0007] Therefore, a practical necessity exists of making a portable cork-screw which with
a simple design may be quickly, comfortably and simply applied to all types of corks
independently from their features and sizes.
[0008] The solution to the above problem has been solved by the cork-screw of the present
invention, by which it is possible to uncork in a really effective way, in any type
of situation, and with corks whose sizes may be very short, short, medium, long and
very long, for which the cork-screw has been provided with two support arms on the
upper edge of the bottle rim, both arms having different sizes, namely, a reduced
one and the other with normal length, the first of these arms being incorporated in
the second arm and both fastened to the cork-screw body by means of a single, union
point and both crossed by a same pin which pivots them to the body, such that when
the cork is penetrated with the cork screw spiral, totally independent support points
may be available within the same assembly, without being separated parts and without
having also separated supports or fastenings, both arms being found in the same space
and permitting that the spiral penetrates in the cork until a desired position, adjusting
this penetration to the length of the cork and without completely passing through
it if not desired.
[0009] As a result of the arrangement of the short arm, housed or incorporated in the longer
one, the size of the cork-screw is effectively reduced by several centimetres with
respect to similar ones in the current state of the art, such that an object results
which may be easily carried in the user's pocket.
[0010] As will be understood, depending on the length of the cork, either the shorter or
longer arm may be used. Activation of the cork-screw body in its approach movement
to the bottle to lean on the selected arm, makes the other arm, as relevant, to automatically
separate from the bottle, leaving the space free for the easy handling of the assembly.
This characteristic will be explain with greater detail below.
[0011] On the other hand, the invention foresees that the cork-screw body incorporates,
as has been said, decapsulating means, which preferably consist of small curved, chamfered
portions integrated with the body, made in an arched recess, provided in a part of
said body. The arrangement of this portions, together with the own shape and sizing
of the mentioned recess, make the decapsulating operation, clean, comfortable, fast
and effective.
Brief Description of the Drawings
[0012] These and other features and advantages of the invention may be more clearly understood
by the following detailed description of a preferred embodiment thereof, given only
as an illustrative and non-limiting example, referring to the attached drawing, in
which:
Figure 1 shows a perspective view of a cork-screw constructed according to the present
invention.
Figure 2 shows a side elevated view of the cork-screw applied to a bottle, with the
spiral introduced in the cork carried by the latter, and
Figures 3 to 6 correspond to successive views in the side elevation of sequential
operations related to the removal of a long cork of a predetermined size, with the
use of the cork-screw of the present invention.
Description of the Preferred Embodiment
[0013] According to that expressed above, the detailed description of the preferred embodiment
of the invention will be carried out with the use of the figures of the attached drawings
by which, the same numerical references have been used to mark equal or similar parts.
Therefore, firstly referring to figure 1 of the drawings, the representation may be
seen in perspective of a cork-screw constructed according to the invention in which
a body (1) is seen, consisting of a rigid, longitudinal component, preferably metallic,
as a "C" shaped profile, to whose opposite side walls, a conventional spiral shaped
extraction means (2) has been articulated, by means of a pin (3) near to one of the
ends, destined to be nailed in the cork by means of a rotational movement identical
to that made with any other known cork-screw. In this same mentioned end, two arms
(4,5) are articulated by means of a same pin (6) and therefore, in a single position,
of which, one arm (4) has considerably less length than the other arm (5), both mentioned
arms having stepped ends for their easier coupling to the upper edge of the bottle
rim carrying the cork to be removed, and of which one of the arms, particularly the
shorter one (4), has a slightly less width and is incorporated or housed in the inner
space of the other arm (5), the latter having a wide opening through which the shorter
one may pass. Moreover, the body (1) has been provided with means to easily decapsulate
the bottle, said means consisting of two small slightly protruding portions (7), made
over the profile of an arched recess made in one of the side walls of the body. The
portion (8), correspondingly in front of the opposite wall, is kept intact, such that
in the decapsulating operation, it serves as a stop for the upper edge of the bottle,
such that it is the own body width (1) which defines the distance to which the cut
should be made over the bottle capsule.
[0014] The design given to the cork-screw assembly being described, allows a considerable
reduction of size (several centimetres with respect to a similar cork-screw), due
to the articulation of both arms at the same point and the possibility of housing
in the closed position of the cork-screw of the shorter one (4) inside the longer
one (5), besides permitting than the body (1) may have an ergonomic shape allowing
a perfect grip by the user for easier handling.
[0015] Referring to figure 2, the representation of an elevated view of the cork-screw of
the invention is seen, applied to a bottle whose neck (9) has the cork (10) to be
removed. In this Figure, the spiral (2) introduced in the cork (10) is seen. Moreover,
said cork has been represented with a dotted line and a considerable length has been
selected to be able to more easily understand the different operations involved in
a complete removal sequence, the latter being represented in Figures 3 to 6.
[0016] In fact, once the spiral is introduced as shown in Figure 2, the following stage
to remove a cork (10) consists in supporting the shorter arm (4), taking advantage
of the stepping of its free end, over the bottle neck (9) rim, when the position of
the cork-screw will be that shown in Figure 3. By suitably holding the bottle with
one hand, and applying an upwards pulling effort with the other hand, taking advantage
of the lever effect provided by such a support, the cork is removed until a position
similar to that shown in Figure 4. It will be understood that if said cork (10) is
short or very short, this movement will be sufficient to completely remove it, the
removal operation finishing here, with the sole use of the shorter arm (4).
[0017] However, when a longer cork (10) is used and this first operation is not sufficient
to remove it, the second support, of a greater height is used, provided by the longer
arm (5). For this reason, once the first removal operation has finished, and with
the assembly in the position shown in said figure 4, it will be enough to make the
body (1) descend, such that the shorter arm, dragged by the body itself, is automatically
separated from the bottle neck and in its place, the longer arm (5) may be applied,
taking advantage of the stepping of its free end, as shown in Figure 5 of the drawings.
In this situation, it is sufficient to apply an adequate upwards pull over the body
(1) to pass to the position of figure 6 and therefore, total removal of the cork.
[0018] From the above, it is clearly seen that the cork-screw design of the invention permits
a comfortable and simple use thereof, independently from the type of cork in question.
Moreover, the provision of a single articulation pin (6) for both arms (4, 5) with
the body (1) permits the arrangement of relative dragging means, such that when any
coupling or body (1) moving operation is performed, the arm not being used simultaneously
moves with the body, being separated from the application space, and hence not representing
any hindrance to handle the assembly. Finally, it will also be understood that the
incorporated arm arrangement permits that, in the closed cork-screw position, both
arms remain adapted to the body (1), with the spiral (2) inside the latter, hence
occupying a minimum space making it especially recommended to be transported by the
user in a pocket or any other place.
[0019] It is not considered necessary to extend this description for a skilled person to
understand its scope and the advantages derived from the invention, as well as to
develop and implement the purpose thereof.
[0020] Nevertheless, it should be understood that the invention has been described according
to a preferred embodiment thereof, such that it may be modified without this representing
any change of the basis of said invention, said modifications especially including
the shape, the size and/or manufacturing materials.
1. An improved portable cork-screw, applicable to the removal of corks of any size and
characteristic, of the type that may be incorporated in a body to which is articulated
a spiral component that may be nailed by means of a manual rotational movement, in
the cork to be removed, which is characterised in that:
in the end nearest to the articulation of the spiral component (2) said articulation
has been foreseen, in a single area and with the use of a single pin (6), for two
arms (4,5), whose free ends have the formation of a respective stepped edge to provide
supports over the upper edge of the bottle rim (9) carrying the cork (10) to be removed;
said arms (4,5) have different lengths, such that the shortest arm (4) is housed or
embedded inside the longer arm (5) and such that the latter has a wide opening in
the articulation end, through which the shorter arm (4) may pass;
the mentioned body (1) having an open shape with a "C" profile has, in one of its
walls, a wide recess, whose profile preferably adopts an arched shape, in which two
slightly salient protuberances (7) have been formed in predetermined positions, with
a curved chamfered edge, constituting bottle decapsulating means.
2. An improved portable cork-screw, according to claim 1, characterised in that the shorter
arm (4) in its support on the edge of the bottle rim (9), provides sufficient operative
distance for the removal of short or very short corks, while the longer arm (5) provides
sufficient operative distance for the removal of larger corks and in that the mentioned
body (1) also has dragging means destined to automatically separate the arm (4, 5)
not being used during the cork removal operation.
