Abstract
Safety apparatuses for objects having a nut are disclosed. Contemplated apparatuses comprise a nut cap and a nut rotation indicator that can readily be observed by an operator. A retention wall can also be included to operate in conjunction with an additional component to block a rotation of a nut. Apparatuses are preferably configured to remain stable in harsher environments.
Claims21
A safety apparatus comprising:
- a base having a top portion and bottom portion;
- a nut cap rotatably coupled with the base and protruding from the top portion of the base;
- a nut rotation indicator coupled with the nut cap and configured to rotate with the nut cap, the nut rotation indicator positioned under the bottom portion of the base;
- and
- an alert hole in the base and positioned proximate to the nut cap, wherein a rotation of the nut cap causes a portion of the rotation indicator to become exposed through the alert hole.
2 more elements
A safety apparatus comprising:
- a ring-shaped base having a first retention wall, a second retention wall, and a plurality of alert holes;
- wherein each of the plurality of alert holes has a corresponding nut cap having a nut rotation indicator;
- wherein at least one nut cap is rotatably coupled with the ring-shaped base in a manner allowing at least a portion of its nut rotation indicator to be viewed through a corresponding alert hole.
