Bottle neck gripper
View Patent ↗A bottle neck gripper includes first and second jaw components, each pivotally mounted for rotation about a respective pivot axis, the first jaw component including a first permanent magnet mounted thereon, the second jaw component including a second permanent magnet mounted thereon. The first permanent magnet and second permanent magnet are positioned to be attracted to each other. An attractive force of the magnets urges grip ends of the first and second jaw components toward each other. The pivot axis of the first jaw component is located between the first permanent magnet and the grip end, and the pivot axis of the second jaw component is located between the second permanent magnet and the grip end.
1. A bottle neck gripper, comprising:
a first jaw component mounted for pivot about a first pivot axis, the first jaw component including a first grip part and a first biasing part, wherein the first pivot axis intersects the first jaw component at a first location between the first grip part and the first biasing part, wherein the first jaw component includes a first permanent magnet carried on the first biasing part;
a second jaw component mounted for pivot about a second pivot axis, the second jaw component including a second grip part and a second biasing part, wherein the second pivot axis intersects the second jaw component at a second location between the second grip part and the second biasing part, wherein the second jaw component includes a second permanent magnet carried on the second biasing part;
wherein the first permanent magnet and the second permanent magnet are positioned to be attracted to each other and an attractive force between the first permanent magnet and the second permanent magnet urges the first grip part and the second grip part together;
wherein the first pivot axis is substantially parallel to the second pivot axis, wherein the first pivot axis is spaced apart from the second pivot axis, wherein a distance between the first permanent magnet and the second pivot axis is smaller than a distance between the second permanent magnet and the second pivot axis, wherein a distance between the second permanent magnet and the first pivot axis is smaller than a distance between the first permanent magnet and the first pivot axis.
2. The bottle neck gripper of claim 1 , wherein the first grip part includes a first distal end and the second grip part includes a second distal end, wherein the bottle neck gripper includes a resting state in which the first distal end and the second distal end are spaced from each other by a first linear distance to define a passage for entry of a bottle neck.
3. The bottle neck gripper of claim 2 , wherein insertion of the bottle neck into the passage moves the first distal end and the second distal end away from each other against the attractive force between the first permanent magnet and the second permanent magnet, wherein the first grip part and the second grip part are shaped to define a neck retaining mouth inward of the passage, wherein entry of the bottle neck into the neck retaining mouth allows the first distal end and the second distal end to move back toward each other as a result of the attractive force between the first permanent magnet and the second permanent magnet.
4. The bottle neck gripper of claim 1 , wherein the first jaw component comprises a plastic material and the first permanent magnet is encased within the plastic material of the first jaw component, and the second jaw component comprises a plastic material and the second permanent magnet is encased within the plastic material of the second jaw component.
5. The bottle neck gripper of claim 2 , wherein the first pivot axis is separated from the second pivot axis by a second linear distance, wherein a bisecting plane bisects the first linear distance and the second linear distance and runs substantially parallel to the first pivot axis and the second pivot axis, wherein the first distal end is positioned on a first side of the bisecting plane and the first permanent magnet is positioned on a second side of the bisecting plane, wherein the second distal end is positioned on the second side of the bisecting plane and the second permanent magnet is positioned on the first side of the bisecting plane.
6. The bottle neck gripper of claim 1 , wherein the first biasing part includes a projecting finger on which the first permanent magnet is carried, the second biasing part includes a leg on which the second permanent magnet is carried, the leg including an opening, the second permanent magnet located between a distal end of the leg and the opening, wherein the finger is positioned in the opening to position the first permanent magnet in proximity to the second permanent magnet.
7. The bottle neck gripper of claim 6 , wherein the opening is sized larger than the finger to allow movement of the finger within the opening as the first jaw component and the second jaw component pivot during engagement with a bottle neck.
8. A bottle neck gripper, comprising:
a first jaw component mounted for pivot about a first pivot axis, the first jaw component including a first grip part and a first biasing part, the first biasing part carrying a first permanent magnet;
a second jaw component mounted for pivot about a second pivot axis, the second jaw component including a second grip part and a second biasing part, the second biasing part carrying a second permanent magnet;
wherein the first grip part includes a first distal end and the second grip part includes a second distal end, wherein the bottle neck gripper includes a resting state in which the first distal end and the second distal end are spaced from each other by a first linear distance to define a passage for entry of a bottle neck;
wherein the first pivot axis is substantially parallel to the second pivot axis, wherein the first pivot axis is separated from the second pivot axis by a second linear distance, wherein a bisecting plane bisects the first linear distance and the second distance and runs substantially parallel to the first pivot axis and the second pivot axis, wherein the first distal end is positioned on a first side of the bisecting plane and the first permanent magnet is positioned on a second side of the bisecting plane, wherein the second distal end is positioned on the second side of the bisecting plane and the second permanent magnet is positioned on the first side of the bisecting plane;
wherein the second permanent magnet of the second biasing part is located toward a distal end of the second biasing part;
wherein the first permanent magnet of the first biasing part overlies a portion of the second biasing part that is spaced from both the distal end of the second biasing part and the second permanent magnet.
9. The bottle neck gripper of claim 8 , wherein the first permanent magnet and the second permanent magnet are positioned to be attracted to each other and an attractive force between the first permanent magnet and the second permanent magnet urges the first grip part and the second grip part together.
10. A bottle neck gripper, comprising:
a first jaw component mounted for pivot about a first pivot axis, the first jaw component including a first grip part, the first jaw component carrying a first permanent magnet;
a second jaw component mounted for pivot about a second pivot axis, the second jaw component including a second grip part, the second jaw component carrying a second permanent magnet;
wherein the first jaw component includes a projecting finger on which the first permanent magnet is carried, the second jaw component includes a leg on which the second permanent magnet is carried, the leg including an opening, wherein the finger is positioned in the opening to position the first permanent magnet in proximity to the second permanent magnet.
11. The bottle neck gripper of claim 10 , wherein the second permanent magnet is located between a distal end of the leg and the opening.
12. The bottle neck gripper of claim 10 , wherein the first permanent magnet and the second permanent magnet are positioned to be attracted to each other and an attractive force between the first permanent magnet and the second permanent magnet urges the first grip part and the second grip part together.
