Abstract
A coupling assembly for safety headwear is provided. The coupling assembly includes one or more apertures within safety headwear, such as a hard hat, and a coupling structure that couples to the one or more apertures. The coupling structure includes one or more surfaces that interface with the safety headwear. The coupling structure includes a protrusion that defines one or more widths, and the protrusion extends through the one or more apertures.
Claims20
A safety headwear system comprising:
- a safety headwear comprising:
- a shell formed from a rigid material, the shell defining an external surface and an opposing internal surface that defines a cavity sized to receive the head of a wearer, the shell centered on a vertical axis;
- a first aperture extending along the external surface of the shell;
- and
- a second aperture extending along the external surface of the shell;
- an accessory coupled to and configured to be used contemporaneously with the safety headwear;
- and
- a coupling structure comprising:
- a body coupled to the accessory, the body comprising:
- a radially outward facing surface;
- opposing edges that define a first width;
- and
- a projection extending outward from the radially outward facing surface, the projection comprising:
- an outer surface flush with one of the opposing edges of the body;
- and
- an inner surface opposing the outer surface, the inner surface of the projection configured to support the accessory;
- an arm extending downward from the body to an end of the arm;
- a first support surface facing downward, the first support surface comprising two coplanar portions extending away from opposing sides of the arm, the two portions of the first support surface define a first distance apart from each other;
- a second support surface facing downward, the second support surface comprising two coplanar portions extending away from opposing sides of the arm, the two portions of the second support surface define a second distance apart from each other that is less than the first distance;
- and
- a first step surface facing upward away from the end of the arm, the first step surface extending radially inward towards the vertical axis when the coupling structure is coupled to the safety headwear;
- wherein the first step surface extends laterally continuously along an entire second width of a middle portion of the arm, wherein the second width is defined between opposing edges of the first step surface, and wherein the first width is greater than the second width;
- and
- wherein each of the opposing sides of the end of the arm connect to the respective opposing edge of the body via contiguous surfaces, wherein the contiguous surfaces comprise the first support surface and the second support surface.
