Various reusable respirator designs are shown. In one example, a reusable respirator includes an inhalation pathway with a conduit extending from the exterior of the respirator into the nose piece allowing users to receive air directly into an inner sealed zone around a user's nose and mouth. The inhalation pathway includes a vent opening such that the inhalation pathway also directs air into a facemask zone, between the nose piece and an outer seal reducing/preventing shield fogging during inhalation. In another example, the respirator includes cartridge attachment lobes each having a different size and shape. A filter cartridge assembly can only be aligned with the lobes in one orientation, creating a robust connection. In another example, a storage bin for a reusable respirator includes a one-way film placed underneath a plurality of perforations allowing gases and moisture to escape the bin while limiting the ingress of other gases or particles.

Various hard hat fan systems are provided. In a certain embodiment, fan system includes an impact absorbing layer with a channel that defines a recessed surface which extends into the impact absorbing layer away from an inner surface of a shell of a hard hat. Together, the inner surface of the shell and the recessed surface define a duct configured to provide fluid communication between an inlet of the channel and an air vent positioned along the channel. In another embodiment, fan system includes a mounting bracket with first and second cam levers which may be actuated into a locked position, and first and second channels. When in the locked position, the first and second cam levers bias the edges of a mounting ridge of the shell against the first and second channels of the mounting bracket such that the mounting bracket is retained on the shell.

Hard hat with fan

A tool, such as a respirator or gas mask, is provided. The respirator includes a body, a filter, an upper and lower strap, and a locking mechanism. The locking mechanism enables quick-release for fitting and/or adjusting the respirator on a user's head or face. In various embodiments, inelastic and elastic properties of the straps and/or a cord in the entwined region of the locking mechanism enhance the quick-release fit and adjustment of the locking mechanism.

The present disclosure describes clips for lanyards, such as hard hat lanyards. The clips include opposing teeth that move to a closed/clamped position to secure a lanyard to a user, such as to the clothes of a user. The clip includes a body, a lever and a grip. Opposing teeth are located on the grip and body. The clip includes multiple pivoting connections between the body, lever and grip. The teeth on the grip may lie along an arcuate path and/or may have a tooth depth that facilitates engagement with material such as clothing.

Lanyard clip

A lanyard with attachment members such as a tool holding member, tether key, or carabiner, is provided. The lanyard includes one or more elastic cords within a sheath. The sheath has a much lower elasticity than the elastic cord. The higher spring constant or modulus of elasticity of the sheath limits the total extended length of the lanyard in operation. The elastic cords stretch to absorb the energy of falling equipment up to the length of the outer sheath. The attachment members may be attached to the sheath or may include components of the sheath and or the elastic cord. The lanyard allows for an elastic response to absorb the energy of a falling tool and a restraint to the total extended length of the lanyard.
