Abstract

A hose coupling guard including a fixture configured to connect to a hose coupling having a release mechanism, and a cover movably connected to the fixture to be movable between a first position and a second position. The cover includes a shield configured to enclose the release mechanism when the cover is in the first position, and to expose the release mechanism when the cover is in the second position. A display surface may be located on the shield and configured to be oriented to face a location from which an operator can operate the release mechanism.

First claim

The invention claimed is:

1. A hose coupling guard comprising: a fixture configured to connect to a hose coupling having a release mechanism; and a cover movably connected to the fixture to be movable between a first position and a second position, the cover comprising a shield configured to enclose the release mechanism when the cover is in the first position, and to expose the release mechanism when the cover is in the second position, a travel stop to prevent said cover from moving past the second position, said travel stop maintaining a center of gravity of said cover on a first side of a movable connection joining said cover to the fixture throughout movement of said cover between the first position and the second position such that gravitational force applied to the center of gravity of said cover causes said cover to move to the first position from the second position, wherein the fixture comprises a crossbeam configured to span a side of the hose coupling and a U-bolt configured to surround an opposite side of the hose coupling and be secured to the crossbeam, and wherein a return spring operatively connected between the cover and the fixture and configured to bias the cover to the first position.

2. The hose coupling guard of claim 1 , where in the cover further comprises a display surface on the shield and configured to be oriented to face a location from which an operator can operate the release mechanism.

3. The hose coupling guard of claim 2 , wherein the display surface is movably mounted to the shield.

4. The hose coupling guard of claim 2 , wherein the display surface comprises a flat panel depicting a warning message.

5. The hose coupling guard of claim 1 , wherein the cover is pivotally connected to the fixture by a hinge.

6. The hose coupling guard of claim 1 , wherein the cover further comprises at least one handle.

7. The hose coupling guard of claim 6 wherein the at least one handle comprises a first handle extending laterally in a first direction from a longitudinal axis of the hose coupling, and a second handle extending laterally in a second direction from the longitudinal axis of the hose coupling.

8. The hose coupling guard of claim 7 , wherein the release mechanism comprises a first lever located on a first lateral side of the longitudinal axis of the hose coupling, and a second lever located on a second lateral side of the longitudinal axis of the house coupling, and, when the cover is in the first position, the first handle is located adjacent the first lever, and the second handle is located adjacent the second lever.

9. The hose coupling guard of claim 1 , wherein the shield comprises a semi-cylindrical panel.

10. The hose coupling guard of claim 1 , wherein the shield comprises a solid enclosure.

11. The hose coupling guard of claim 1 , wherein the release mechanism is movable along a travel path from an engaged position to a disengaged position, and at least a portion of the shield is located in the travel path when the cover is in the first position.

12. The hose coupling guard of claim 1 , wherein the release mechanism comprises a first lever located on a first lateral side of a longitudinal axis of the hose coupling, and a second lever located on a second lateral side of the longitudinal axis of the hose coupling, and the shield is dimensioned to prevent the first lever and the second lever from moving to a respective disengaged position when the cover is in the first position.
