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.

First claim

What is claimed is:

1 . 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.

2 . The lockout device of claim 1 , wherein the cable attachment point and the cable lockout module are positioned on different external sides of the cover such that the internal cavity of the cover is interposed between the cable attachment point and the cable lockout module.

3 . The lockout device of claim 1 , wherein the opening about the internal cavity of the cover has an insert positioned therein, the insert being positioned about a periphery of the opening.

4 . The lockout device of claim 3 , wherein the insert is made from a material that is more compressible than a material of the cover.

5 . The lockout device of claim 4 , wherein the insert is configured to conform to parts of the valve, the valve stem, or the other control or a pipe associated therewith when the lockout device is attached thereto.

6 . The lockout device of claim 1 , wherein the cable engagement element includes a pair of rotatable cleats having the cable-receiving pathway therebetween.

7 . The lockout device of claim 6 , wherein the pair of rotatable cleats both have tips biased toward the cable-receiving pathway.

8 . The lockout device of claim 6 , wherein, when the cable is received in the cable-receiving pathway between the pair of rotatable cleats, the cable is able to be pulled in one direction to reduce a size of the cable loop formed between the cable attachment point and the cable lockout module but is not able to be pulled in the opposite direction to increase the size of the cable loop.

9 . The lockout device of claim 6 , wherein each of the pair of rotatable cleats is biased by a respective torsion spring.

10 . The lockout device of claim 6 , wherein the peripheral walls surround the cable engagement element wherein the pair of rotatable cleats are positioned between the cable entrance opening and the cable exit opening.

11 . The lockout device of claim 10 , wherein the cable exit opening is positioned at an upper end of the peripheral walls and the cable entrance opening is positioned at a lower end of the peripheral walls that opposes the upper end, and the pair of rotatable cleats are interposed between the cable entrance opening at the lower end of the peripheral walls and the cable exit opening at the upper end of the peripheral walls.

12 . The lockout device of claim 1 , wherein the cable attachment point includes a cable opening sized so that the free end of the cable is able to pass through the cable opening, but the securable end of the cable is too large to pass through the cable opening thereby permitting the cable to be secured to the cover by the engagement of the securable end with the cable opening of the cable attachment point.

13 . The lockout device of claim 1 , wherein the door is hinged relative to the remainder of the cable lockout module.

14 . The lockout device of claim 1 , wherein the cable lockout module has a tab with a plurality of lock openings and the door has a slot for receiving the tab when the door is in the closed position.

15 . The lockout device of claim 14 , wherein, when the door is in the closed position, the plurality of lock openings is on a side of the door opposite the cable engagement element.

16 . The lockout device of claim 14 , wherein the plurality of lock openings is sized to receive a shackle of a padlock to lock the door in the closed position.

17 . The lockout device of claim 1 , wherein the peripheral walls surround the cable engagement element and the cable entrance opening and the cable exit opening accommodate passage of the cable therethrough.

18 . A method of attaching the lockout device of claim 1 to the valve, the valve stem, or other control to lock out the valve, the valve stem, or other control, the method comprising:
placing the internal cavity of the cover over at least part of the valve, the valve stem, or other control;
wrapping the free end of the cable around either the valve, a valve associated with the valve stem, or other control, or an associated pipe therewith; and
placing the free end of the cable within the cable-receiving pathway of the cable engagement element to form the cable loop.

19 . The method of claim 18 , further comprising the steps of:
closing the door of the cable lockout module; and locking the door in the closed position to prevent a removal of the free end of the cable from the cable-receiving pathway of the cable engagement element and thereby preventing the cable loop from being broken.

20 . The method of claim 19 , further comprising the step of pulling the cable through the cable-receiving pathway of the cable engagement element to reduce the size of the cable loop.

21 . 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
