Abstract
A method and apparatus for locking a hose onto a hose coupling for a valve. A rigid linkage is pivotally mounted adjacent to the valve with a hose engaging member at a first end and an actuator engaging member at a second end. The linkage is pivoted to position the hose engaging member in the engaged position overlying and maintaining in engagement a hose with the hose coupling. A manual valve actuator of the valve is moved to a first position with the valve open. The actuator engaging member engages the manual valve actuator to prevent pivoting of the linkage and maintain the hose engaging member in the engaged position until the manual valve actuator has been returned to a second position with the valve closed.
Claims7
A hose coupling lock for a valve, comprising:
- a support;
- a linkage pivotally mounted to the support, the linkage having a first end and a second end;
- a hose engaging member at the first end of the linkage;
- an actuator engaging member at the second end of the linkage;
- such that by pivoting the linkage, the hose engaging member is movable between an engaged position and a disengaged position, in the engaged position the hose engaging member overlies and maintains in engagement a hose with a hose coupling of a valve, the actuator engaging member engaging a manual valve actuator of the valve when in a first position with the valve open to prevent pivoting of the linkage and maintain the hose engaging member in the engaged position until the manual valve actuator has been moved to a second position with the valve closed.
A hose coupling lock for a valve, comprising:
- a support collar;
- a rigid “Z” shaped linkage having an upper arm, a lower arm and a diagonal connective member, the linkage being pivotally secured to the support collar by a horizontal pivot pin the extends through the linkage where the lower arm meets the diagonal connective member, the linkage having a first end and a second end;
- at least one arcuate hose engaging member at the first end of the linkage;
- an actuator engaging member at the second end of the linkage;
- such that by pivoting the rigid linkage, the hose engaging member is movable between an engaged position and a disengaged position, in the engaged position the hose engaging member overlies and maintains in engagement a hose with a hose coupling of a valve, the actuator engaging member engaging a manual valve actuator of the valve when in a first position with the valve open to prevent pivoting of the rigid linkage and maintain the hose engaging member in the engaged position until the manual valve actuator has been moved to a second position with the valve closed.
A method of locking a hose onto a hose coupling for a valve that has a manual valve actuator with a first position and a second position, in the first the valve being open and when in the second position the valve being closed, comprising the steps of:
- pivotally mounting a linkage adjacent to the valve, the linkage having a first end and a second end, a hose engaging member being positioned at the first end of the linkage and an actuator engaging member being positioned at the second end of the linkage, such that by pivoting the linkage, the hose engaging member is movable between an engaged position and a disengaged position;
- pivoting the linkage to position the hose engaging member in the engaged position overlying and maintaining in engagement a hose with the hose coupling of the valve;
- moving the manual valve actuator to the first position with the valve open, the actuator engaging member engaging the manual valve actuator to prevent pivoting of the linkage and maintain the hose engaging member in the engaged position until the manual valve actuator has been returned to the second position with the valve closed.
