Abstract
A strand grab includes a frame including a mounting portion and a hook portion having a first end attached to the mounting portion and extending in an arc shape to a second end, a gate member rotatably attached to the mounting portion, a jaw member rotatably attached to the mounting portion, and a connector member coupled between the gate member and the jaw member. The gate member, the jaw member, and the connector member are operatively coupled such that when the gate member rotates toward the first end of the hook portion, the connector member causes the jaw member to rotate toward the first end of the hook portion.
Claims19
An apparatus for use with a ladder, the apparatus comprising:
- a frame including a mounting portion and a hook portion having a first end attached to the mounting portion and extending in an arc shape to a second end;
- a gate member rotatably attached to the mounting portion of the frame at a first pivot;
- a jaw member rotatably attached to the mounting portion of the frame at a second pivot;
- and
- a connector member coupled between the gate member and the jaw member,
- wherein the gate member is rotatable between a first position proximate the second end of the hook portion and a second position proximate the first end of the hook portion,
- wherein the gate member is structured to rotate from the first position toward the first end of the hook portion when the strand grab is lowered onto a strand such that the strand applies a force against the gate member, and
- wherein the gate member, the jaw member, and the connector member are operatively coupled such that when the gate member rotates toward the first end of the hook portion, the connector member causes the jaw member to rotate toward the first end of the hook portion.
A ladder comprising:
- a pair of rails;
- a pair of rungs extending between the rails;
- a mounting piece attached between the pair of rungs;
- and
- an apparatus rotatably attached to the mounting piece, the apparatus including:
- a frame including a mounting portion and a hook portion having a first end attached to the mounting portion and extending in an arc shape to a second end;
- a gate member rotatably attached to the mounting portion of the frame at a first pivot;
- a jaw member rotatably attached to the mounting portion of the frame at a second pivot;
- a connector member coupled between the gate member and the jaw member,
- wherein the gate member is rotatable between a first position proximate the second end of the hook portion and a second position proximate the first end of the hook portion,
- wherein the gate member is structured to rotate from the first position toward the first end of the hook portion when the apparatus is lowered onto a strand such that the strand applies a force against the gate member, and
- wherein the gate member, the jaw member, and the connector member are operatively coupled such that when the gate member rotates toward the first end of the hook portion, the connector member causes the jaw member to rotate toward the first end of the hook portion.
