A load binder including a clamp mechanism for clamping onto container members such side boards of a shipping container. The clamp mechanism includes arms having connecting members adapted to couple to a binding strap, as well as gripping members and a gripping pad adapted to clamp against the container member in response to an urging of connecting members towards one another. The arms and the gripping pad may be pivotal about a common axis. Further enhanced binding action may be achieved via a cam buckle provided with double lining.
1. A container member clamp, comprising:
a pair of arms pivotal about a common axis, each having an opposite curvature and/or straight portions, the arms having an outboard portion and an inboard portion;
gripping members coupled to the outboard portions that are adapted to engage an edge and/or back side of a container member;
a gripping pad rotatably disposed about said axis and adapted to engage a front side of the container member,
connecting members coupled to the inboard portions, the connecting members adapted for engagement with a binding strap, wherein application of a force on the binding strap directed away from the clamp urges the connecting members towards one another,
which results in application of a clamping force on the container member caused by the gripping members becoming closer to the gripping pad.
2. The container member clamp of claim 1 , wherein the gripping pad is offset with respect to the axis such that the gripping pad can have a first position and a second position relative to the gripping members, the first position having a greater distance between the gripping members in an open configuration.
3. The container member clamp of claim 2 , wherein the gripping pad is resistively rotatable about the axis.
4. The container member clamp of claim 1 , wherein the arms include:
upper arms that are curved between an outer end of the outboard portion and an inner end of the inboard portion; and
a pair of lower arms disposed on an opposite side of the gripping pad from the upper arm, the lower arms having oppositely curved inboard portions that generally correspond to curvature of the inboard portion of the upper arms, the lower arms each having a first end pivotal about the axis and a second end coupled to a corresponding connecting member.
5. The container member clamp of claim 1 , wherein the binding strap is provided with a single end loop that engages both of the connecting members, wherein the force directed away from the clamp urges elongation of the loop and thus causes rotative closure of the inboard portions of the arms.
6. The container member clamp of claim 5 , wherein the connecting members are rotatably coupled to the inboard portions of the arms to help avoid sliding movement of the end loop relative to the connecting members.
7. The container member clamp of claim 1 , wherein the arms are generally C-shaped and have a consistent radius of curvature.
8. The container member clamp of claim 1 , wherein the gripping members and/or the connecting members are sleeved to enhance gripping and/or reduce wear.
9. The container member clamp of claim 1 , wherein said binding strap includes a reversing loop that allows the strap to be double lined to increase leverage and thus the force directed away from the clamp.
