Abstract
A clamp for a hose comprising a drum which is confined for rotation within a clip. The axis of rotation of the drum is aligned with the longitudinal axis of the hose. Bands, which are connected to the clip and encircle the hose, are attached to the drum. A bolt or screw head axially accessible at an end of the drum is rotated by a tool to wind the bands onto the drum and tighten them against the hose. The clip includes latch members that engage gears on the drum to maintain tension on the bands and prevent unwanted backwinding.
Claims15
A clamp for a hose comprising:
- a drum having detent means and an annular bearing surface;
- a resilient strip having a first end portion looped around said bearing surface for rotatably holding said drum with its axis of rotation substantially in alignment with the longitudinal axis of a hose to be clamped;
- a strap means secured to said strip and releasably attached to said drum for being wound thereon;
- and,
- implement engagement means on said drum accessible for connection with an implement from a direction parallel to the longitudinal axis of a hose to be clamped, said strip consisting of a singular homogenous structure having a mid-body portion which is folded about said strap means and, spaced-apart strip elements which diverge from the folded mid-body portion to positions proximate respective opposing sides of said mid-body portion and merge into a second end portion, said second end portion positioned over at least a part of said first end portion with a stop means integral with said second end portion comprising at least one latch member extending from said second end portion for releasably engaging said detent means and preventing the rotation of said drum in a predetermined direction.
