DETAILED DESCRIPTION OF THE INVENTION
Referring to the drawings and initially to FIGS. 1-3, a corkscrew in accordance with the preferred embodiment of the present invention comprises a support member 2 having two opposite elongated sliding slots 21, a movable rod 22 slidably mounted in the sliding slots 21 of the support member 2, a resting member 3 pivotally mounted on the support member 2, a screw member 4 pivotally mounted on the support member 2, a cover 5 mounted on the support member 2, and a pull handle 6 having a first end pivotally mounted on the cover 5 and formed with a protruding tongue 61 located between the sliding slots 21 of the support member 2 and the movable rod 22.
The support member 2 has a first end provided with an extension 20 having two downward extending side walls 24, and each of the sliding slots 21 of the support member 2 is formed in a respective side wall 24 of the support member 2. The first end of the support member 2 is formed with a receiving recess 26 connected to the extension 20 to receive the first end of the pull handle 6. The extension 20 of the support member 2 has a substantially inverted U-shaped cross-sectional profile.
The movable rod 22 is movable in the extension 20 of the support member 2 and has two opposite ends each slidable in a respective sliding slot 21 of the support member 2.
The cover 5 is enclosed around an outer periphery of the support member 2 so that the support member 2 is fully hidden in the cover 5. The cover 5 has a substantially inverted U-shaped cross-sectional profile and has an inside formed with a receiving chamber 50 to receive the support member 2 and to receive the first end of the pull handle 6. The cover 5 has a first end pivotally mounted on a mediate portion of the support member 2 and a second end pivotally mounted on the first end of the pull handle 6.
The first end of the pull handle 6 is formed with a recessed receiving portion 60 rested on the extension 20 of the support member 2. The tongue 61 of the pull handle 6 is perpendicular to the support member 2. The tongue 61 of the pull handle 6 is movable in the extension 20 of the support member 2 and is movable to rest on the movable rod 22.
Thus, the pull handle 6 is pivotable relative to the support member 2 between a first position where the pull handle 6 is in line with the support member 2, and the tongue 61 of the pull handle 6 is spaced from the movable rod 22, and a second position where the pull handle 6 is inclined relative to the support member 2, and the tongue 61 of the pull handle 6 is rested on the movable rod 22.
The corkscrew further comprises a blade 62 pivotally mounted on a second end of the pull handle 6, and the second end of the pull handle 6 is formed with a receiving groove 64 to receive the blade 62. The blade 62 is received in the receiving groove 64 of the pull handle 6 at a normal state to reduce the whole volume of the pull handle 6.
The screw member 4 is pivotally mounted on the first end of the support member 2 and located under the first end of the pull handle 6.
The resting member 3 is pivotally mounted on a second end of the support member 2 and is provided with a recessed resting portion 31.
In operation, referring to FIGS. 3 and 4 with reference to FIGS. 1 and 2, the resting member 3 and the screw member 4 are expanded outwardly from the support member 2, and the pull handle 6 is in line with the support member 2. Then, the screw member 4 is screwed into a cork 72 of a bottle 70 until the resting portion 31 of the resting member 3 is rested on the mouth 74 of the bottle 70. Then, the pull handle 6 is pulled upward relative to the support member 2 to pull the cork 72 of the bottle 70 upward gradually.
As shown in FIG. 4, when the pull handle 6 reaches the largest rising angle and the user cannot apply the pulling force easily, the pull handle 6 is initially pressed downward relative to the support member 2 and then pulled upward relative to the support member 2. When the pull handle 6 is pressed downward relative to the support member 2, the tongue 61 of the pull handle 6 is movable toward the movable rod 22 to push the movable rod 22 until the tongue 61 of the pull handle 6 crosses a first side of the movable rod 22 and abuts a second side of the movable rod 22. When the pull handle 6 is pulled upward relative to the support member 2, the tongue 61 of the pull handle 6 is movable to rest on the movable rod 22 to reduce the rising angle of the pull handle 6, so that the user can pull the pull handle 6 successively to pull the cork 72 of the bottle 70 upward until the cork 72 is removed from the bottle 70.
Accordingly, the angle between the pull handle 6 and the support member 2 is adjustable when the pull handle 6 reaches the largest rising angle, so that the user can pull the pull handle 6 upward relative to the support member 2 to pull the cork 72 of the bottle 70 upward successively until the cork 72 is removed from the bottle 70 so as to remove the cork 72 from the bottle 70 easily and conveniently. In addition, the pull handle 6 is pivotable relative to the support member 2 to remove the cork 72 from the bottle 70 by a leverage action, so that the user can remove the cork 72 from the bottle 70 easily and quickly, thereby facilitating the user removing the cork 72 from the bottle 70.
Although the invention has been explained in relation to its preferred embodiment(s) as mentioned above, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the present invention.
