Abstract
Abstract An elastic pipe-connecting component for pipes or pipelines or the like, comprises an elastic sleeve with flanges at each end and an annular expansion bulge in its midportion. In its undeformed condition, there is a cylindrical section on each side of the bulge, between the bulge and the portion of the component that is clamped to the pipe or pipeline. These exposed cylindrical portions are adapted to expand outwardly, to form two additional bulges, upon the imposition of pressure. To this end, they are reinforced with fibers of glass or steel or high strength synthetic, which are disposed at an angle to the axis of the component, of less than 55°. A desirably long component is thus provided, from a minimum of material.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
140 words
An elastic component containing reinforcing fibers, having a pair of radially outwardly extending end flanges and snap-flanges disposed endwise inwardly from said radially extending flanges thereby to define a groove between said radially extending flanges and said snap-flanges for the reception of rings by which each end of the component is secured to an adjacent pipe or pipeline or the like, said component having an outwardly extending annular bulge at its midportion and a locally reinforced cylindrical portion on each side of said bulge between said bulge and the adjacent said snap-flange, in the undeformed condition of the component, said fibers being disposed at an angle less than 55° relative to the axis of the component whereby, upon the imposition of internal pressure to the component, said cylindrical portions of the component can form two additional radially outwardly extending bulges.
Claim 2
Dependent Claim
140 words
An elastic component containing reinforcing fibers, having a pair of radially outwardly extending end flanges and snap-flanges disposed endwise inwardly from said radially extending flanges thereby to define a groove between said radially extending flanges and said snap-flanges for the reception of rings by which each end of the component is secured to an adjacent pipe or pipeline or the like, said component having an outwardly extending annular bulge at its midportion and a locally reinforced cylindrical portion on each side of said bulge between said bulge and the adjacent said snap-flange, in the undeformed condition of the component, said fibers being disposed at an angle less than 55° relative to the axis of the component whereby, upon the imposition of internal pressure to the component, said cylindrical portions of the component can form two additional radially outwardly extending bulges.
Claim 3
Dependent Claim
30 words
A component as claimed in claim 1, and annular reinforcing rings embedded in said component on each side of the first-mentioned bulge between the first-mentioned bulge and said cylindrical portions.
