Abstract
An improved clamp for hoses and other tubular members includes two rigid clamping members having semi-circular recesses, one or more annular wedge-shaped grooves in the recesses, and fasteners. An elastomeric insert, or a pair of inserts, has one or more ribs shaped to fit the groove or grooves. The rib height is less than the groove depth leaving an annular gap to improve the clamping action. Inserts of different thickness can be provided to accommodate hoses of different dimensions.
Claims1
In an improved clamping ring assembly for clamping a tubular member, the ring being of the type having first and second bodies formed with semi-cylindrical recesses defining a tubular passage to receive the tubular member, at least one annular groove of predetermined depth in each of said recesses, each said groove being trapezoidal in cross section widening toward the opening thereof, and at least one generally semi-cylindrical elastomeric insert being a radially protruding rib to engage one of said annular grooves, and means for urging said bodies toward each other with said recesses facing each other, the improvement wherein
- each said annular rib is trapezoidal in cross section and is shaped to be received in its associated groove substantially without distortion, and
- the radial dimension of each said rib is significantly smaller than the depth of the associated groove so that a gap remains between the rib and the bottom of the groove when the insert and bodies are assembled.
