Abstract

A quick-connect coupling for a gas line has a socket member for connection t o a gas line and a nipple for connection to a gas appliance, the nipple being engageable in t he socket member for coupling the gas line to the appliance, with a sleeve displaceable betwe en a locking position for securing the nipple in the socket member and a released positio n in which the nipple is free to be uncoupled from the socket member. A locking member is displaceable along a path of movement into an extended position to retain the sleeve in t he locking position. A control knob connected to the gas valve is rotatable for opening and closing the gas valve to control gas flow through the socket member. The control knob ha s an abutment portion movable into the path of movement of the locking member for retainin g the locking member in the extended position, the control knob having an opening in the abutment portion dimensioned to allow sliding displacement of the locking member from the extended position into a retracted position to release the sleeve from its locking position on rotation of the control knob into a valve-closed position.

Claims (8)

1. A quick-connect coupling for a gas line, the coupling comprising:-a socket member for connection to a gas line;
a nipple for connection to an gas appliance, the nipple being engageable in the socket member for coupling the gas line to the appliance;
a sleeve displaceable between a locking position for securing the nipple in the socket member and a released position in which the nipple is free to be uncoupled from the socket member;
a locking member displaceable into an extended position in which the locking member retains the sleeve in the locking position;
a gas valve for controlling gas flow through the socket member; and a control knob connected to the gas valve and rotatable for opening and closing the gas valve;
the control knob having an abutment portion movable into the path of movement of the locking member for retaining the locking member in the extended position;
and the control knob having an opening in the abutment portion and the opening being dimensioned to allow sliding displacement of the locking member from the extended position and into a retracted position to release the sleeve from its locking position on rotation of the control knob into a valve-closed position.
2. A gas flow control device as claimed in claim 1, including a spring biasing the slide member towards its extended position.
3. A gas flow control device as claimed in claim 2, wherein the spring is located in the control knob.
4. A gas flow control device as claimed in claim 4, wherein the spring is a spiral spring.
5. A gas flow control device as claimed in claim 1, 2 or 3, wherein the abutment portion comprises a circularly curved peripheral surface of the control knob.
6. A gas flow control device as claimed in claim 1, 2 or 3, wherein the gas valve has a valve housing, the locking member has a body portion slidable between the control knob and the valve housing and formed with a slot and the control knob has a stem extending into the slot for connection to the gas control valve, the slot being dimensioned to allow the sliding displacement of the locking member into and out of the extended position and the locking member including a stop displaceable into the opening in the abutment portion of the control knob in the valve- closed position of the control knob.
7. A gas flow control device as claimed in claim 6, wherein the gas control valve housing has a convex outer surface and the locking member has a concave surface complimentary to and opposed to the convex outer surface and slidable along the convex outer surface on movement of the locking member into and from the path of movement of the sleeve.
8. A gas flow control device as claimed in claim 8, wherein the convex outer surface is of hexagonal cross-section.
