Abstract
A lockout device can be used to secure a valve, a valve stem, or other control. The lockout device includes a cover having an internal cavity and an opening about the internal cavity, a cable that is flexible, a cable attachment point attached to the cover to which the cable is attached at its securable end, and a cable lockout module attached to the cover. The cable lockout module includes a cable engagement element having a cable-receiving pathway extending therethrough for reception of a free end of the cable and selective securement thereof to create a cable loop. The cable lockout module further has a door. When the door is in a closed position, the cable engagement element is securely covered by the door and the door is lockable relative to a remainder of the cable lockout module to prevent the door from being opened.
Claims21
A lockout device for securing a valve, a valve stem, or other control, the lockout device comprising:
- a cover having an internal cavity and an opening about the internal cavity, the internal cavity for receiving at least a part of the valve, the valve stem, or the other control;
- a cable extending from a securable end to a free end, the cable being flexible;
- a cable attachment point attached to the cover, the cable being attached at the securable end of the cable to the cable attachment point;
- and
- a cable lockout module attached to the cover, the cable lockout module including a cable engagement element contained therewithin in which the cable engagement element has a cable-receiving pathway extending therethrough for reception of the free end of the cable and selective securement thereof to create a cable loop between the cable attachment point and the cable lockout module, and the cable lockout module further having a base with a door connected thereto, the door movable between an opened position and a closed position in which the door provides access to the cable engagement element, the cable engagement element being operable whilst the door is in the opened position to receive the cable in the cable receiving pathway and to hold the cable even while the door remains in the opened position preventing the cable from being pulled in one direction under tension;
- wherein, when the door is in the closed position, the cable engagement element is securely covered by the door and the door is lockable relative to a remainder of the cable lockout module to prevent the door from being taken out of the closed position while locked;
- wherein truncated teeth on the door in conjunction with openings on a peripheral wall of the base of the cable lockout module define a cable entrance opening and a cable exit opening.
A lockout device for securing a valve, a valve stem, or other control, the lockout device comprising:
- a cover having an internal cavity and an opening about the internal cavity, the internal cavity for receiving at least a part of the valve, the valve stem, or the other control;
- a cable extending from a securable end to a free end, the cable being flexible;
- a cable attachment point attached to the cover, the cable being attached at the securable end of the cable to the cable attachment point;
- and
- a cable lockout module attached to the cover, the cable lockout module including a cable engagement element contained therewithin in which the cable engagement element has a cable-receiving pathway extending therethrough for reception of the free end of the cable and selective securement thereof to create a cable loop between the cable attachment point and the cable lockout module, and the cable lockout module further having a door movable between an opened position and a closed position in which the door provides access to the cable engagement element, the cable engagement element being operable whilst the door is in the opened position to receive the cable in the cable receiving pathway and to hold the cable even while the door remains in the opened position preventing the cable from being pulled in one direction under tension;
- wherein, when the door is in the closed position, the cable engagement element is securely covered by the door and the door is lockable relative to a remainder of the cable lockout module to prevent the door from being taken out of the closed position while locked;
- wherein the cable-receiving pathway extends between a cable entrance opening and a cable exit opening in which the cable-receiving pathway extends from the cable entrance opening at a lower end of a peripheral wall of a base of the cable lockout module, between a pair of rotatable cleats as the cable engagement element, and to the cable exit opening at an upper end of the peripheral wall of the base.
