Abstract
A coupling device is adapted for attachment to an elastomeric tubular body having integral, looped reinforcement fibers as part of a tubular assembly. The coupling device includes a coupling member, a stem and a mechanism for retaining the elastomeric tubular body in sealing engagement with the stem when connected therewith. The retaining mechanism maintains this engagement by being interposed within loops of the reinforcement fibers to limit axial movement of the reinforcement fibers relative to the stem. Thus, the grommet retained coupling and the elastomeric tubular body are maintained in spaced relation to and sealing engagement with each other.
Claims18
A coupling device adapted for attachment to an elastomeric tubular body having integral looped reinforcement fibers as part of a tubular assembly, said device comprising:
- a coupling member;
- a stem connected to said coupling member;
- said stem having at least one annular depression disposed thereabout for receiving a portion of said reinforcement fiber loops within;
- and
- ring means for constrictively retaining said reinforcement fiber loops within said annular depression and said elastomeric tubular body in sealing engagement with said stem, when connected therewith, by interposition within loops of said looped reinforcement fibers to limit axial movement of said reinforcement fibers and said elastomeric tubular body relative to said stem.
A coupling device adapted for attachment to an elastomeric tubular body having integral looped reinforcement fibers as part of a tubular assembly, said device comprising:
- a coupling member;
- a stem connected to said coupling member;
- and
- a plurality of hooks disposed about said stem for interposition within said reinforcement fiber loops to limit axial movement of said reinforcement fibers and said elastomeric tubular body relative to said stem.
In an inflatable packer of the type having an elastomeric bladder with integral reinforcing fibers, and coupling means adjoining said elastomeric bladder for attaching said inflatable packer to a well string and the like, said coupling means having a coupling member, a stem, and means for retaining said elastomeric bladder in secure, sealed position with said stem, the improvement wherein said reinforcing fibers are looped, and said retaining means being said stem having at least one annular depression disposed thereabout for receiving a portion of said reinforcement fiber loops within, and ring means for constrictively retaining said reinforcement fiber loops within said annular depression interposed within the loops of said reinforcing fibers to limit the axial movement of said integral reinforcement fibers and said elastomeric bladder relative to said stem.
In an inflatable packer of the type having an elastomeric bladder with integral reinforcing fibers, and coupling means adjoining said elastomeric bladder for attaching said inflatable packer to a well string and the like, said coupling means having a coupling member, a stem, and means for retaining said elastomeric bladder in secure, sealed position with said stem, the improvement wherein said reinforcing fibers are looped, and said retaining means being a plurality of hooks disposed about said stem and interposed within the loops of said reinforcing fibers to limit the axial movement of said integral reinforcement fibers and said elastomeric bladder relative to said stem.
In an elastomeric hose assembly of the type having an elastomeric tubular structure with integral reinforcing fibers, and coupling means adjoining said elastomeric tubular structure for attaching said hose assembly to other hose assemblies and structures, said coupling means having a coupling member, a stem, and means for retaining said elastomeric tubular structure in adjoined, sealed position with said stem, the improvement wherein said reinforcing fibers are looped, and said retaining means being said stem having at least one annular depression disposed thereabout for receiving a portion of said reinforcement fiber loops within, and ring means for constrictively retaining said reinforcement fiber loops within said annular depression interposed within the loops of said integral reinforcing fibers to limit the axial movement of said integral reinforcement fibers and said elastomeric tubular structure relative to said stem.
In an elastomeric hose assembly of the type having an elastomeric tubular structure with integral reinforcing fibers, and coupling means adjoining said elastomeric tubular structure for attaching said hose assembly to other hose assemblies and structures, said coupling means having a coupling member, a stem, and means for retaining said elastomeric tubular structure in adjoined, sealed position with said stem, the improvement wherein said reinforcing fibers are looped, and said retaining means being a plurality of hooks disposed about said stem and interposed within the loops of said integral reinforcing fibers to limit the axial movement of said integral reinforcement fibers and said elastomeric tubular structure relative to said stem.
