Compressible cargo bar
View Patent ↗A cargo bar for retaining loads in a cargo container having opposing side walls. The cargo bar includes telescoping sections and end devices at the opposed ends of the cargo bar. The end devices are elastameric and absorb excessive forces that induce pressure grip extension of the telescoping sections.
1. A support member adapted to help restrain cargo movement comprising:
an extendable support member
a support end gripping member having
a first end adapted to grippingly engage a side member;
a second end including a flange made of resilient material that helps couple the support end gripping member to an end of the extendable support member such that upon transmission of a force caused at least in part by an overthrow distance on the support end gripping member by the extension of the extendable support member, the support end gripping member will deform enough to absorb the force caused by the overthrow distance and achieve locking of the support member between the side member and an opposing side member.
2. The support member of claim 1 , wherein the support end gripping member is made at least in part of a resilient material that provides resistive absorption of said overthrow distance and further induces pressure gripping of the support member to opposing side members.
3. The support member of claim 1 , wherein the first end includes gripping nodules adapted to grippingly engage the side member and compress upon transmission of the force caused by the overthrow distance.
4. The support member of claim 1 , wherein the flange is secured in the end of the extendable support member by a retaining member passing through a hole in the flange, whereby transmission of the force caused by the overthrow distance causes an elongation of the hole in the flange.
5. The support member of claim 1 , wherein a desired gripping pressure is determined, and the support end gripping member is configured to absorb a gripping pressure that exceeds the desired gripping pressure.
6. The support member of claim 1 , wherein the flange further comprises a shoulder adapted to engage the end of the extendable support member.
7. The support member of claim 6 , wherein the shoulder is spaced a selected distance away from the end of the extendable support member when no force is being transmitted such that the flange will be able to compress the selected distance before the shoulder engages the end of the extendable support member.
8. The support member of claim 7 , wherein the shoulder is a resilient material that is adapted to deform upon engagement with the end of the extendable support member end to help absorb the force.
9. The support member of claim 6 , wherein the shoulder is touching the end of the extendable support member end when there is no force being transmitted, the shoulder being adapted to deform upon transmission of the force.
10. A support end gripping member comprising:
a first end adapted to grippingly engage a side member;
a second end including a flange made of a resilient material that is adapted to couple the support end gripping member to an end of a support member such that upon transmission of a force on the support end gripping member by the support member, the support end gripping member will deform enough in a generally linear fashion with respect to a longitudinal axis of the support member to absorb the force caused by an overthrow distance and achieve locking of the support member between opposing side members.
11. A support member adapted to help restrain cargo movement comprising:
an extendable support member
a support end gripping member having
a first end adapted to grippingly engage a side member;
a second end including a flange made of resilient material that helps couple the support end gripping member to an end of the extendable support member such that upon transmission of a force caused by an overthrow distance on the support end gripping member by the extension of the extendable support member, the support end gripping member will deform enough to absorb the force caused by the overthrow distance and achieve locking of the support member between the side member and an opposing side member; and
wherein the flange is secured in the end of the extendable support member by a retaining member passing through a hole in the flange, whereby transmission of the force caused by the overthrow distance causes an elongation of the hole in the flange.
12. The support end gripping member of claim 10 wherein the flange is secured in the end of the support member by a retaining member passing through a hole in the flange, whereby transmission of the force caused by the overthrow distance causes an elongation of the hole in the flange.
13. The support end gripping member of claim 11 wherein the first end includes gripping nodules adapted to grippingly engage a side member and compress upon transmission of the force caused by the overthrow distance.
