Lockout device and method for its use
View Patent ↗A lockout device for preventing an electrical switch from being turned either ON or OFF while the lockout device is attached to the switch. The present lockout device can be capable of quick and easy attachment to the switch and can be secured to the switch with a padlock or similar locking device. The present lockout device can also have a peg for attaching a lockout tag, which prevents the tag from being removed while the lockout device is connected to a switch.
1. A lockout device comprising:
a housing comprising a housing opening;
a frame located within the housing opening, wherein the frame comprises a front end further comprising a front frame opening and a rear end further comprising a rear frame opening, and the frame further comprising a rear clutch comprising a rear clutch opening connected to the rear end of the frame and a front clutch comprising a front clutch opening connected to the front end of the frame;
a sliding bar having a first end and a second end, wherein a jaw, having primary jaw teeth and secondary jaw teeth, is connected to the first end of the sliding bar and the second end of the slide bars configured to pass through the front clutch opening, the front frame opening, then the rear clutch opening, and the rear frame opening; and
a handle having a first end and a second end, wherein the first end is pivotably connected to both the housing and the frame and is configured to move between an open configuration wherein the second end of handle is away from the bar and a closed configuration wherein the second end of the handle is closer to the bar, wherein movement of the handle from the open configuration to the closed configuration causes the jaw to move toward the frame.
2. The lockout device described in claim 1 , wherein the handle comprises a loophole at its second end configured to accept a padlock shank.
3. The lockout device described in claim 2 , wherein the loophole is configured such that placing the padlock shank through the loophole when the lockout device is in a closed configuration prevents the handle from moving into the open configuration.
4. The lockout device described in claim 1 , wherein the rear clutch acts as a release when moved into a position roughly perpendicular to the sliding bar, allowing the sliding bar to pass through a rear clutch opening.
5. The lockout device described in claim 1 , wherein the housing comprises a peg configured to receive a lockout tag hole.
6. The lockout device described in claim 5 , wherein the handle is configured to lock a lockout tag onto the peg when the handle is in the closed configuration.
7. The lockout device as described in claim 4 , wherein the handle is configured to prevent access to the rear clutch when the handle is in the closed configuration.
8. The lockout device described in claim 1 , wherein the frame comprises frame teeth.
9. The lockout device described in claim 8 , wherein the primary jaw teeth, secondary jaw teeth, and frame teeth comprise a serrated metal edge.
10. The lockout device described in claim 1 wherein the jaw further comprises tertiary jaw teeth.
11. The lockout device as described in claim 10 , wherein the primary jaw teeth, secondary jaw teeth, tertiary jaw teeth, and frame teeth comprise a serrated metal edge.
