Quick installation coupling
The present disclosure relates to an installation ready housing type pipe coupling for creating a sealed connection between coaxial groove ended pipes, a hold open clip for the coupling, and other modifications and improvements thereof. The coupling comprises a first and second housing segments creating a cavity, a gasket provided within the cavity, a first and second bolts and nuts connecting the hosing segments at opposite ends, and a hold open clip. The first nut is affixed to the first bolt. The second nut can be adjusted along the second bolt. The hold open clip helps to attach the two housing segments in the preassembled state while keeping the coupling open. The hold open clip may also indicate a proper installation of the coupling.
1. A coupling configured for connecting two grooved pipe ends, comprising
a first and second housing segments, each comprising
an arcuate center portion, wherein an interior surface of the center portion comprising two arcuate keys for engaging the grooves of the two pipe ends;
a first bolting portion, comprising a first bolt hole and a first coupling bolt pad; and
a second bolting portion, comprising a second bolt hole and a second coupling bolting pad,
wherein the interior surfaces of the first and second housing segments are facing each other, creating a center cavity;
a gasket located within the center cavity;
a first bolt connecting the first and second housing segments through the first bolt holes of the first bolting portions of each of the first and second housing segments;
a first nut affixed to the first bolt;
a second bolt connecting the first and second housing segments through the second bolt holes of the second bolting portions of each of the first and second housing segments;
a second nut that is adjustable along the second bolt; and
a hold open clip comprising
a mounting portion comprising an opening that accommodates the first bolt and extending in a longitudinal direction and a width direction, wherein the opening does not allow passage of the first nut or a bolt head of the first bolt;
a tab connected to a side of the mounting portion and having an outer edge; and
wherein the tab is bent relative to the mounting portion while the tab extends away from the mounting portion, whereby the outer edge is located outside of the mounting portion.
2. The coupling of claim 1 , wherein the mounting portion is flat.
3. The coupling of claim 1 , wherein the mounting portion is bent.
4. The coupling of claim 3 , wherein the mounting portion is flattened when the coupling is tightened.
5. The coupling of claim 1 , wherein the tab extends over a part of the side of the mounting portion.
6. The coupling of claim 1 , wherein the tab comprises a first tab and a second tab that are connected to opposite sides of the mounting portion.
7. The coupling of claim 1 , wherein each of the outer edges is slopped, and the hold open clip is mounted to the first bolt in an orientation that a thicker side of the hold open clip is located away from a center of the coupling.
8. The coupling of claim 1 , wherein the hold open clip maintains the coupling in a spaced apart configuration when the coupling is not tightened.
9. The coupling of claim 1 , wherein the tab pivots away from the mounting portion so that the hold open clip is flattened when the coupling is tightened.
10. The coupling of claim 1 , wherein the hold open clip is formed from at least one selected from a group comprising sheet metal, stamped metal, cast metal, machined plastic, and molded plastic.
