Abstract
A protective cap to cover impalement hazards, by means of increasing the surface area associated with said hazard may include utilizing a metal plate embedded within a plastic/polymer cap, with a flat top and a receiving shaft housing below, with mechanical means of securing the cap to said hazard with a mechanical plunger. The mechanical plunger is driven from the exterior of the housing by means of rotating a threaded shaft to selectively engage the impalement hazard and compressively hold the protective cap to the impalement hazard.
Claims21
A protective cap for impalement hazards comprising:
- a housing with an impact surface and a body portion extending away from the first impact surface, the body portion having a sidewall defining a void having a generally rectangular portion, the sidewall forming a side portion with flat surfaces along the generally rectangular portion of the void and a concave channel extending from the generally rectangular portion of the void between the flat surfaces so that a flat surface is disposed on opposing sides of the concave channel;
- and
- a plunger at least partially disposed in the generally rectangular portion of the void, the plunger comprising arms disposed in alignment with the flat surfaces of the sidewall and a concave depression formed into the plunger between the arms.
A protective cap for attachment on an impalement hazard, comprising:
- a housing having a generally flat impact surface and a body portion extending away from the generally flat impact surface, the body portion having a sidewall defining a void, the sidewall forming a plurality of steps, each step of the plurality of steps having a concave channel formed therein for engaging one side of an impalement hazard, and
- a plunger disposed within the void, the plunger having a concave depression formed therein generally opposite of and in alignment with the concave channels formed in the plurality of the steps for engaging an opposing side of an impalement hazard to hold the impalement hazard against the sidewall of the body portion.
A method for securing an impalement hazard, the method comprising:
- selecting an impalement hazard cap having a first, impact surface portion and a second, body portion defining a void;
- disposing an end of the impalement hazard within the void;
- and
- advancing a bolt to advance a plunger disposed in the void to engage the impalement hazard and push or maintain the impalement hazard in contact with an opposing side of the second, body portion to thereby compressively engage the impalement hazard between the plunger and the sidewall of the second, body portion, and wherein the sidewall has flat portions so that the plunger may hold rectangular structures between the plunger and the flat portions of the sidewall, and wherein the plunger has a concave depression and the sidewall contains a concave channel in alignment with the concave depression such that impalement hazards having a square or round cross-section can be disposed in the concave depression and concave channel to hold the impalement hazard between the plunger and the sidewall in the concave depression and the concave channel.
