Hose clamp

摘要

A hose clamp includes a band and a worm drive mechanism. The band has a set of slots located between a first and second circumferential end of the band. The worm drive mechanism is connected to the band and causes radial contraction of the band to tighten the band. The worm drive mechanism includes a screw that engages the set of slots for radial contraction of the band. A clamping-pressure-restoring construction is provided in order to maintain a seal between the hose clamp and an underlying hose during use of the hose clamp and when the underlying hose experiences size expansion and contraction due to, for example, temperature fluctuations.

主权项

1. A hose clamp, comprising:
a band having a first circumferential end, a second circumferential end, and a plurality of slots located between said first and second circumferential ends, said band having a first axial end and a second axial end, said first and second circumferential ends and said first and second axial ends being defined relative to a generally circular shape presented by said band during use of the hose clamp, and said band extending from said first axial end to said second axial end along a generally arcuate path, said band further having a pocket defined at an underside of said band by the generally arcuate shape; and a worm drive mechanism connected to said band and operable to radially contract said band during a tightening action of the hose clamp, said worm drive mechanism including a screw with an at least partially threaded shank that engages said slots of said band upon rotation of said screw to cause the radial contraction of said band, the connection between said worm drive mechanism and said band including at least one hook with a free end located at said pocket.
