Abstract
An anti-pivot and lock mechanism for a clamp including a horizontal post connected and moveable relative to a vertical post. The mechanism engages the vertical post and horizontal post above or below a pivot axis of the horizontal post to prevent or minimize pivoting movement of the horizontal post between changes of consecutive clamped workpieces.
Claims9
A clamp, comprising:
- a component engagement member including a clamp head operatively connected to a handle;
- a guide arm operatively connected to the component engagement member at a first end of the guide arm, and the guide arm has an opening at a second end distal the first end and the guide arm has a central axis from the first end to the second end;
- a first post extending through the opening and in sliding engagement with the guide arm, and the first post has a first side facing the component engagement member and a second side opposite the first side, wherein the guide arm has a pivot axis at the second end thereof relative to the first post and the pivot axis is perpendicular to the central axis of the guide arm;
- a second post at an end of the first post and disposed generally perpendicular to the first post and having a first end connected to the first post and a second end, distal the first end, and the second end is disposed opposite the clamp head;
- and,
- an anti-pivot and lock mechanism includes a magnet assembly magnetically connected to the first side of the first post and to the guide arm adjacent to the opening of the guide arm, wherein the anti-pivot and lock mechanism engages the first post above or below the pivot axis and central axis of the guide.
An anti-pivot and lock mechanism for a clamp including a guide arm that has an opening at an end thereof and a clamp post extending through the opening and in sliding engagement with the guide arm, wherein the anti-pivot and lock mechanism, comprises:
- a first magnet mounted to a first base member;
- a second magnet mounted to a second base member;
- and,
- wherein the first and second base members are pivotal relative to one another to a locked position, so the first magnet magnetically affixes to the clamp and the second magnet magnetically affixes to the guide arm.
An anti-pivot and lock mechanism for a clamp including a horizontal post operatively connected to a vertical post and at least one pivot axis associated with the connection of the horizontal post to the vertical post, wherein the anti-pivot and lock mechanism, comprises:
- a magnet assembly including a first magnet pivotally connected to a second magnet;
- and,
- the first and second magnets are pivoted to a locked position, wherein the first magnet is configured to magnetically engage the vertical post and the second magnet is configured to magnetically engage the horizontal post.
