Lockout device

Abstract

A fitting lockout device includes first and second plate members each having proximal and distal end portions. The first plate member has at least a first cutout disposed between the proximal and distal end portions, and at least a first lock aperture disposed in the distal end portion. The second plate member has at least a second cutout disposed between the proximal and distal end portions, and at least a second lock aperture disposed in the distal end portion. The proximal end portion of the first plate member is pivotally connected to the proximal end portion of the second plate member such that the first and second plate members may be pivoted to align the first and second lock apertures for receipt of a locking member therethrough. When the first and second lock apertures are aligned, the first and second cutouts overlap to define an opening for securely retaining a recessed portion of a fitting.

Claims

1. A lockout device for obstructing use of a fitting having an outer recessed portion, the lockout device comprising: a first plate member comprising proximal and distal end portions, at least a first cutout disposed between the proximal and distal end portions, and at least a first lock aperture disposed in the distal end portion; anda second plate member comprising proximal and distal end portions, at least a second cutout disposed between the proximal and distal end portions, and at least a second lock aperture disposed in the distal end portion;wherein the proximal end portion of the first plate member is pivotally connected to the proximal end portion of the second plate member such that the first and second plate members may be pivoted to align the first and second lock apertures for receipt of a locking member therethrough;further wherein when the first and second lock apertures are aligned, the first and second cutouts overlap to define an opening for securely retaining the outer recessed portion of the fitting.

2. The lockout device of claim 1, wherein the first plate member comprises a first set of cutouts and the second plate member comprises a corresponding second set of cutouts, wherein when the first and second lock apertures are aligned, each of the first set of cutouts overlaps a corresponding one of the second set of cutouts to define an opening for retaining the outer recessed portion of a corresponding fitting.

3. The lockout device of claim 2, wherein when the first and second lock apertures are aligned, at least two of the openings defined by the corresponding ones of the first and second cutout are sized to accommodate different sized fittings.

4. The lockout device of claim 1, wherein the first and second plate members each comprise a plurality of lock apertures.

5. The lockout device of claim 1, further comprising a first notched blade portion extending from the distal end portion of the first plate member, and a second notched blade portion extending from the distal end portion of the second plate member, wherein the first and second notched blade portions are configured to abut each other when the first and second lock apertures are aligned.

6. The lockout device of claim 5, wherein the first and second notched blade portions comprise interlocking slots.

7. The lockout device of claim 5, wherein the first and second notched blade portions are each bent at an angle with respect to the corresponding distal end portion.

8. The lockout device of claim 5, wherein the first and second notched blade portions are substantially identical.

9. The lockout device of claim 1, wherein the first cutout extends to a side edge of the first plate member, and the second cutout extends to a side edge of the second plate member.

10. The lockout device of claim 1, wherein the first and second cutouts are substantially identical.

11. The lockout device of claim 1, wherein the first and second plate members are substantially identical.

12. A lockout arrangement for a conduit, the lockout arrangement comprising: a fitting for assembly with the conduit, the fitting comprising an outer recessed portion;a first plate member comprising proximal and distal end portions, at least a first cutout disposed between the proximal and distal end portions, and at least a first lock aperture disposed in the distal end portion; anda second plate member comprising proximal and distal end portions, at least a second cutout disposed between the proximal and distal end portions, and at least a second lock aperture disposed in the distal end portion;wherein the proximal end portion of the first plate member is pivotally connected to the proximal end portion of the second plate member such that the first and second plate members may be pivoted to align the first and second lock apertures for receipt of a locking member therethrough;further wherein when the first and second lock apertures are aligned, the first and second cutouts overlap to define an opening for securely retaining the outer recessed portion of the fitting.

13. The lockout arrangement of claim 12, wherein the first plate member further comprises a third cutout disposed between the proximal and distal end portions, and the second plate member comprises a fourth cutout, wherein when the first and second lock apertures are aligned, the third and fourth cutouts overlap to define a second opening for securely retaining an outer recessed portion of a second fitting.

14. The lockout arrangement of claim 12, wherein the outer recessed portion of the fitting is configured to engage a corresponding feature on a mating connection to connect the fitting to the mating connection, such that retention of the outer recessed portion by the first and second plate member prevents connection of the fitting with the mating connection.

15. A method for obstructing use of a fitting having an outer recessed portion, the method comprising: providing a first plate member comprising at least a first cutout extending from a side edge of the first plate member, and at least a first lock aperture disposed in a distal end portion of the first plate member;providing a second plate member comprising at least a second cutout extending from a side edge of the second plate member, and at least a second lock aperture disposed in a distal end portion of the second plate member;pivotally connecting a proximal end portion of the first plate member to a proximal end portion of the second plate member;positioning the first and second plate members to receive an outer recessed portion of a fitting;pivoting at least one of the first and second plate members to a lockout position in which the outer recessed portion of the fitting is securely retained between the first and second cutouts; andlocking the first and second plate members in the lockout position.

16. The method of claim 15, wherein locking the first and second plate members in the lockout position comprises inserting a locking device through aligned lock apertures in the first and second plate members.

17. The method of claim 15, wherein pivoting at least one of the first and second plate members to the lockout position comprises abutting a first notched blade portion on the first plate member with a second notched blade portion on the second plate member.

18. The method of claim 15, further comprising securing the first and second plate members to a structure by a lanyard assembled with at least one of the first and second plate members.

19. The method of claim 15, wherein pivotally connecting a proximal end portion of the first plate member to a proximal end portion of the second plate member comprises riveting the first plate member to the second plate member.

20. The method of claim 15, wherein providing the second plate member comprises providing a plate member substantially identical to the first plate member.
