Self-centering and self-gripping corkscrew

摘要

A self-centering and self-gripping corkscrew is provided. A centering and locking mechanism is integrated into the bottle receiving opening of the corkscrew such that in one downward motion a bottleneck is securely gripped and automatically centered under the cork removing device (e.g., a worm screw). The centering and gripping mechanism is spring biased downward and utilizes compression techniques configured into an outer mechanism (contained within the bottle receiving opening of corkscrew) and the body of the corkscrew to simultaneously grip and align the bottle with the axis of the cork removing device. The locking mechanism is part of the centering mechanism and allows the corkscrew to remain locked onto the bottleneck (after centering and gripping) during activation of the cork removing device and removal of the corresponding cork. An upward motion opposite the locking motion disengages the mechanism, removing the corkscrew from the bottle.

主权项

1. A corkscrew comprising:
a body having a bottle receiving opening; a cork-removing device positioned within the body; and a self-centering and self-gripping mechanism positioned within the bottle-receiving opening of the body, and being configured to receive, secure and center a bottleneck received therein with the cork-removing device; the self-gripping mechanism comprising:
an inner mechanism configured to engage the bottleneck; andan outer mechanism concentrically positioned around the inner mechanism and configured to compress the inner mechanism around the bottleneck without requiring activation of the cork-removing device; the self-centering mechanism comprising:
a centering and locking mechanism cooperatively formed into the body and the outer mechanism;at least one guide positioned on the outer mechanism; andat least one guide surface integrated into or on the body and configured to receive the at least one guide on the outer mechanism, said at least one guide surface angularly extending toward an axis of the cork removing device.
