20220364666, Nov 17, 2022

Filed:

Appl. No.:

17/838709

Inventors:

- Corona CA, US

International Classification:

F16L 37/092
F16L 21/08
F16L 21/02
F16L 21/00

Abstract:

A fitting for a pipe has a cylindrical sleeve and a spigot fitted concentrically within the sleeve. The sleeve is slidable along the spigot in a proximal direction. The sleeve has a gripper ring cavity with a conical bearing surface with a diameter that is smaller at the distal end and a larger at the proximal end. One or more gripper rings fit within the cavity and slidingly engage the bearing surface. The spigot has an outer surface sized to fit within a proximal end of the pipe. The inner surface of the gripper rings and the outer surface of the spigot define an annular space with a first radial width sized to accept insertion of the proximal end of the pipe. When the sleeve is moved with respect to the spigot in the proximal direction toward a sealed position, the rings are inwardly compressed by the bearing surface to grip an outer surface of the pipe. The end of the pipe is drawn into a space between the sleeve and the spigot with radial width smaller than the first radial width.

Abstract:

Spigot device including a spigot formed with exterior gripping teeth and sleeve device to telescope over the spigot. The sleeve device is formed with a radially inwardly opening, distally contracting conical bearing surface which mounts a radially inwardly contractible gripper ring device captive therein, and constructed to be driven radially inwardly by the bearing surface as the sleeve is drawn proximally on the spigot to grip a plastic pipe trapped in the annulus between the sleeve and spigot.The steps of selecting a spigot device including a distally projecting spigot of a predetermined outside diameter. Selecting a sleeve device formed with a radially inwardly opening interior retainer collar with an interior distally extending and radially and inwardly sloped bearing surface defining a gripper ring cavity. Selecting a gripper ring device which is contractible radially inwardly and inserting in the cavity and retaining the gripper ring device in the cavity to cooperate with the outside diameter to form an annulus for receipt of the plastic pipe and causing the gripper ring device to grip the pipe.
