In the first embodiment shown in FIGS. 1 to 7, the corkscrew according to the invention is constituted by a cylindrical body 1 formed by two semicircular shells 2, 2. I have. The semicircular shells are connected in parallel by studs 6 which are accommodated in corresponding holes in the shell. Once assembled, the two shells 2 are housed in a sheath 4 and the entire shell is retained.

The two shells 2 are provided in the longitudinal direction with a groove 8 having a rectangular cross section, and a parallelepiped formed by two parts, ie, a head 12 and a nut 14, in the groove. The sliding movement of the sliding member 10 is surely guided. The nut 14 is substantially cubic in shape and extends upward by two tongues 16,
These tongues are located in correspondingly shaped receiving grooves 18 cut out in the head 12. In the upper part of the tongue 16, a hole 19 penetrates and receives an opposing catch 20, which catches and retracts under the action of a compression spring 21 disposed therebetween. 12 is attached. In this way, the two parts constituting the slide portion 10, that is, the head 12 and the nut 14, are securely connected.

The upper part of the head 12 is connected to the grip 7, and the lower part thereof is provided with an orifice 13. The orifice 13 suspends the stopper screw 22.

These suspension support means are constituted by a bush 15 and a nut 25, and the screw 22 is freely rotatable with respect to the head 12 and is supported in the longitudinal direction. . The lower part of the screw 22 is a nut 1
4 penetrates in the longitudinal direction, for which purpose the nut is formed with a hole suitable for the helical shape of the screw 22. However, as shown in FIG. 4, the nut preferably has a screw 22
A central longitudinal hole 26 close to the outer diameter of the two cylindrical studs 2
The axes of these studs are perpendicular to the longitudinal axis yy 'of the corkscrew and are offset from one another in the longitudinal and transverse directions.

At the bottom of the upper part of each groove 8 is recessed a recess 28, an elastic blade 30 is fixed above the groove, and a stud 32 is provided at the base of the elastic blade 30. It has a diameter and a length that can be located inside the hole 19 of the part 16. The blade 30 has sufficient rigidity to move the stud 32 with a force greater than the spring force of the spring 21 in the direction of the corkscrew axis yy ', so that when the device is not used, the stud 32 is Presses the catch 20 against the spring 21 and is located in the hole 19 of the tongue 16, thus, on the one hand, the nut 14 is kept stationary with respect to the corkscrew body 1 and, on the other hand, FIG. 4, the nut is unlocked from the head 12.

Each of the two shells 2 has a longitudinal inner groove 33 that is open at the lower part, and these two grooves are arranged at the upper part of the cylindrical body 36. Slide body 3
4 for receiving the cork stopper 5 from the cork stopper body 1 when the cork stopper 5 is to be removed from the bottle neck 3.

The two slides 34 are provided on their outer surfaces with stoppers 37 for limiting the strokes of the slides in the grooves 33.

The compression spring 3 is provided between the base of the main body 1 and the upper part of the cylindrical body 36.
5, and the compression spring connects the cylindrical body 36 to the main body 1.
Has the effect of separating from.

The lower part of the blade 30 and the outer lower part facing the slide body 34 are inclined, and as a result, when the slide body 34 rises against the action of the compression spring 35, each slide body The beveled portion abuts the corresponding sloping portion of the tongue 30 and pushes the tongue outward, as shown in the right half of FIG. And as a result, the two parts of the slide member 10, namely the head 12 and the nut 14, are connected.

In order to center bottlenecks 3 of different diameter, a deformable clamping element 40 is provided on the tubular body 36. This clamping element comprises a cylindrically shaped first part or base 40a fixed to the inner surface of the tubular body 36, and a plurality of vertically elongated grooves 41 cut into the tongues 39 which are elastically deformed therebetween. And a second upper portion 40b having a beveled truncated shape. As shown in FIG. 6b, when the bottle neck 3 is located in the clamping element 40, it hits the tongues 39 and deforms them, and by their reaction the tongues automatically center the neck 3 Position it securely.

Under such conditions, the automatic corkscrew according to the invention functions as described below and schematically shown in the detailed drawings of FIGS. 1a to 1e and FIGS. 2 to 6.

First, the corkscrew is placed at the start position shown in FIG. 1A, and the head 12 is separated from the nut 14 by pulling the grip member 7. In this position, the compression spring 35 actually moves the tubular body 36 away from the base of the main body 1 and
The slide body 34 is pushed downward (left half in FIG. 4), so that the studs 32 push each of the catches 20 inward, thereby preventing the connection between the head 12 and the nut 14 on the one hand, and on the other hand Then, the connection between the nut 14 and the main body 1 is prevented.

As shown in FIG. 1 b and FIG. 6 b, the neck 3 of the bottle containing the cork stopper 5 to be subsequently removed is introduced into the crumb member 40, and the longitudinal acting force F _{1 is applied} to the main body 1, When the spring 35 is compressed to the maximum, this causes the slide body 3
The slanted upper part 4 corresponds to the slanted lower part of the resilient blade 30, thus pushing the stud 32 outward as shown in the right half of FIG. When acting force F _'1 in the same direction acts on the gripping member 7 in the same direction at the same time, while moving the head 12 downward, rotating the extraction screw 22 extending through the nut 14, shown in FIGS. 1b and 6b Is inserted into the cork stopper 5 as described above.

When the head 12 comes to the end of its stroke, the catch 20 faces the hole 19 of the disengaged tongue 16 and the catch enters into the hole and thus the head 1
2 and the nut 14 are securely connected.

In the corkscrew operation according to the present invention, in the second or withdrawal phase shown in FIGS. 1 c and 6 c, the acting force in the direction opposite to the acting force F ′ ₁ preceding the gripping member 7. F ′ ₂ acts, thereby moving not only the head 12 but also the nut 14 connected thereto upward. During this movement, there is no relative movement between the two parts, so that the withdrawal screw 22 does not undergo a rotational movement and the cork stopper 5 is withdrawn from the neck 3.

[0044] represented in FIGS. 1d and Fig. 6d, is located between the third stage or lowering phase of the operation of the corkscrew according to the present invention, pressed gripping member 7 is F 'to the _first direction, thereby The head 12 and the nut 14 return to the lower end of the stroke.

As shown in FIGS. 1e and 6e, during the fourth or ejection phase of the operation of the device according to the invention, an upwardly acting force F′2 is exerted on the gripping member 7. Works. In the resulting movement, the spring 35 is
, Whereby the inclined part of the slide 34 is moved away from the corresponding part of the tongue 30, as shown in the left part of FIG.
2 is located in the hole 19 of the tongue 16, which results in the catch 20 being forcibly retracted, while connecting the nut 14 to the body 1 and the head 12
And the nut 14 is disconnected. During this movement, the head 12 is therefore lifted, so that the withdrawal screw 22 rotates with respect to the cork stopper 5 and thus the cork stopper is removed.

It will be appreciated that according to the present invention, a simple handle 7 with a gripping member attached directly to the head 12, such as a common corkscrew, for example, as shown in particular in FIG. Some types of booster means, such as a widely used type of lever system, may be substituted.

Naturally, according to the invention, the locking and unlocking means and the means for releasing the unlocking means are produced by a device different from that described with reference to FIGS. 1 to 7. Can be.

For example, as shown in FIGS. 8 and 9, the head 12 and the nut 14
Are securely locked by the joint action of the two resilient blades 44 fixed to them, the blades terminating at their front ends with hooks 43, which are in their normal position, i.e. under stress. When the head 12 is not located, it is located in a notch 45 provided at the front end of the nut 14, whereby the head 12 and the nut 14 are securely connected.

The device comprises unlocking means 47 constituted by a long member, said member being mounted to move along the longitudinal axis yy ′ of the corkscrew and by means of elastic means 49 the arrow F _3. , And comes into contact with the base of the hook 43. The resilient means 49 is capable of deforming the tongue piece 44 outwardly, which releases the hook 43 from the notch 45, thus releasing the head 12 from the nut 14.

The device also comprises means for releasing the unlocking means 47, schematically shown by a transversely pulling element 50, which is pivotally connected to said element 47, The element can be removed from the base of the hook 43. In this way, the hook 43 that has once been removed returns to the notch 45 again as shown in FIG. 9, and thus the head 12 and the nut 14 are connected.

Other means for removing the unlocking means to ensure the connection between the head 12 and the nut 14 can be used within the scope of the invention.

For example, FIG. 10 and others show a modified embodiment of the present invention.

In these figures, it is assumed that the reference numerals of the corresponding parts used earlier are marked with '.

The corkscrew thus consists essentially of a tubular body formed by two identical shells 2 ′, said shells being provided with studs 6 located in corresponding holes in these shells. 'Are connected together. The assembled two shells 2 'are screwed into a sheath 9', which is made up of three parts 9'a, 9'b and 9'c, and the assembly is securely held.

The two shells 2 ′ have a narrow groove 8 ′ provided in the center in the longitudinal direction, the base of which ends in a lateral groove 8 ′ a. The longitudinal groove 8 'reliably guides the movable slide 10' in the shell.

The slide part 10 ′ comprises three substantially cylindrical elements,
That is, it is constituted by the upper head 12 ', the intermediate bush 13, and the lower nut 14'.

The head 12 ′ is formed with an upper part of a cylindrical member having the same diameter as the inner diameter of the shell 2 ′ arranged diametrically opposite, and the radial guide stud 60 is provided with a groove in the length direction of the shell 2 ′. Each moves in 8 '. Below this upper part,
A small-diameter cylindrical portion 62 extends and its end is divided by a longitudinal groove 63 into four diametrically opposed radial stops 64. As shown in FIG. 13, the portion 62 has an axial cylindrical bored cavity in which a ball bearing 66 is accommodated, and the bearing rotates a pin 65 to which a corkscrew bit 22 'is fixed. Hold freely.

The intermediate bush 13 is constituted by a cylindrical cylindrical element, and ends in a lower part with a circular boss 67. The boss is radially provided with two diametrically opposed studs 68 which move in respective grooves 8 'and 8'a of the shell 2'. On the upper part of the bush 13, four radial inner stoppers 69 are provided at 90 ° intervals, and their width is slightly smaller than the width of the groove 63 in the longitudinal direction. These stoppers are
As shown in the figure, two diametrical shafts uu 'are 4
It is provided so as to form an angle α close to 5 °. The upper part of the bush 13 is provided with four lengthwise grooves 72, which are particularly provided with stoppers 69 and have elasticity. Due to this elasticity, the stopper 64 disposed on the base of the head 12 ′ enters the bush 13 by pressing the stopper 69, and secures the connection by sliding between the head 12 ′ and the bush 13, while being described later. Thus, these two members can be freely rotated.

The nut 14 ′ comprises a cylindrical upper part 74, a large-diameter base 76 and two diametrically opposed studs 78, which move in the grooves 8 ′ when operating the corkscrew. It has become. The interior of the nut 14 ', not shown or described below, is the same as the nut used in the previous embodiment, receives the bit 22', and is positioned between the head 12 'and the nut 14'. The rotation of the bit is ensured when there is a significant longitudinal movement. The nut 14 'is located at the base of the bush 13. For this purpose, the bush is provided with a double groove, a lateral groove 80 and a longitudinal groove 82, which comprises:
The stud 78 is brought closer to the lateral groove 80. The elastic means constituted by the torsion spring 79 acts to separate the stud 68 from the stud 78 as shown in FIG. This is because as soon as the nut 14 'is placed in the bush 13, the studs are in the relative angular position shown in FIG.

As in the previous embodiment, the device comprises a control member 34 ′, making it possible to suppress the unlocking means present between the head 12 ′ and the nut 14 ′. The control means 34 'is constituted by a washer 84, which is provided with longitudinal tabs 86 which extend upwardly and whose upper part is the longitudinal axis of the corkscrew. The panel 88 is inclined at about 45 ° with respect to yy ′. A compression spring 90 is disposed between the shell 2 'and the control member 34' to keep the member away from the stud 68 when not compressed. The means for guiding this control member 34 ', when moved upwards, comes into contact with the studs 68 by means of a slanted panel 88 against the force of the spring 90, which are pressed at an angle and the shaft yy for corkscrew removal. 'Move along.

As in the previous embodiment, the base of the device is provided with guide means 40 for securely positioning the assembly in the center of the bottle neck 3.

In these conditions, the corkscrew functions as described below.

When the head 1 is not operated, that is, when no stress is applied to the cork opener, the head 1
2 'is in the bush 13 and the slide 10' assembly is in the lower position, so that the bit 22 'projects below the slide 10'. The stud 78 of the nut 14 'is in the coarse groove 8'. A relative torsional moment acts between the nut 14 'and the bush 13 by the torsion spring 79, separating the stud 78 and the stud 68, and these studs act on the bottom of the lateral groove 8'a, respectively. . Under these conditions, as can be seen in FIG. 10, the stopper 69 overlaps the groove 63 at the same longitudinal axis, and as a result, the head is bushed by the upward pulling force of the gripping member 7 of the head 12 '. 13 and lift the head above the corkscrew in this way. Such an operation corresponds to the operation state schematically shown in FIG. 1a.

Next, when the base of the corkscrew is brought into contact with the bottle neck 3, the control member 34 ′ rises against the compressive force provided by the spring 90, and the inclined panel 88 causes the stud 68 to remove the corkscrew. Is pressed at an angle to the longitudinal axis yy ′, whereby the bush 13 rotates and the stopper 69 moves the head 1
It will face the stopper 64 of 2 '. The head 12 'is then pushed downward with a force F1, as shown in FIG. 1b, and during such downward movement of the head 12', the bit 22 'twists and turns within the nut 14, thereby causing a rotational movement. Given
Drive the bit into cork 5. At the end of the downward stroke, the stopper 64 of the head 12 'and the stopper 69 of the bush 13 come into contact with each other, and when further downward force acts, the bush is deformed by the elasticity of the vertical groove 72, The lock state is reached, the click state becomes recognizable, and the user is notified that the downward stroke has been completed.

In this position, the element 34 ′ acts on the stud 68 such that the stud 68 is on the axis yy ′ of the corkscrew, so that the stud 64 of the head and the stop 64 of the bush are engaged. Head 12 'and bush 1
3 is fixed.

As shown in FIG. 1c, a vertical lifting force F2 acts on the head 12 ', and the connection between the head 12' and the bush 13 raises the slide 10 assembly. 22 'does not move, and the cork stopper 5 is pulled out of the bottleneck 3 in such a state.

When the cork stopper 5 is removed, the cork stopper is removed from the bottleneck, and as a result,
In such a state, the control member 34 'is in a lower position where it does not act. Then, as shown in FIG. 1d, when a vertical force acts on the head 12 ', the slide 10 assembly descends, and when this assembly comes to a lower position,
Element 34 'is deactivated, and torsion spring 79 then biases stud 68 to the bottom of each groove 8'a, causing bush 13 to rotate about 45 °. Therefore, the bush takes the angular position shown in FIG. 10, and in these states, the stopper 69 is in a position where it resists the groove 63, and as a result, the head 12
The upward movement acting on 'separates head 12' from bush 13. During this movement, as shown in FIG. 1e, the passage of the bit 22 'through the nut 14' causes the bit to rotate and disengage it from the cork stopper 5. Then, head 12 '
Return to the cork opener and return to the starting position.

Such an embodiment is of particular interest in that it allows the construction of simple parts, most of which can be obtained by moulding, which can be particularly advantageous in terms of cost. Things.
