Abstract
A T-bolt clamp includes a circumferentially extending band and a fastening assembly that employs a T-bolt to tighten the clamp by turning a nut to draw loop ends of the band toward each other. One of the loop ends includes a slotted opening that permits a head of the T-bolt to be inserted and removed without removing the nut from the T-bolt. The fastening assembly is configured to constrain first and second bearing loops of the slotted loop end against movement away from each other during tightening of the clamp. Protrusions on the head of the T-bolt can be used to perform the constraining function by engaging slots in the bearing loops.
Claims19
A T-bolt clamp, comprising:
- a band having first and second loop ends and a body that extends circumferentially between the first and second loop ends;
- and
- a fastening assembly connected to the loop ends and including a T-bolt fastener, a trunnion, and a nut,
- the T-bolt fastener comprising a T-bolt having a head and a threaded shank, wherein the head engages the first loop end and the threaded shank extends from the head to the second loop end,
- the trunnion being connected to the second loop end with the shank extending through the trunnion, and
- the nut being threaded onto the shank and engaging the trunnion, wherein the loop ends are drawn toward each other to tighten the clamp when the nut is further threaded onto the shank to draw the trunnion toward the head of the T-bolt;
- wherein the first loop end includes a slotted opening that permits the head of the T-bolt to be inserted into and removed from the first loop end without removing the nut from the threaded shank, the slotted opening defining first and second bearing loops in the first loop end that retain the head of the T-bolt in the first loop end during tightening of the clamp, and
- wherein the head of the T-bolt includes a protrusion received by a slot in one of the bearing loops.
