A recessed lighting fixture providing illumination from a light source including a plurality of light emitting diodes (LEDs) placed within a cavity of a planar surface, such as a ceiling, wall, or shower. The fixture comprises a baffle integrated with a low profile heat sink that is used to draw heat out of the fixture and communicate that heat to a trim ring of the fixture for dissipation of the heat in the room so that higher intensity light sources can be used. Improved grounding of the recessed trim unit to the recessed housing is provided with combination support and grounding springs. One embodiment of the light source is fixed in position while a second embodiment is gimbal mounted for aiming the light produced by the fixture.

A hanger bar for supporting a recessed light fixture is attachable to ceiling joists or a T-bar grid of a drop down ceiling. First and second bars of the hanger bar slide and telescope. First and second spring clips are detachably coupled to the brackets at the ends of the first and second bars, respectively. Each of the first and second clips has a pair of downwardly extending arms bent inwardly toward one another, a first leg extending from a first arm, a second leg extending from a second arm, and an outwardly-extending foot on the second leg. The spring clips snap on to the T-bar grid. Each bracket includes a nail that is angled away from the hanger bar and downward so that the nail head is below the level of the hanger bar. The angled nails enable easy hammer strikes to attach the hanger bar to ceiling joists without accidental hammer blows to the hanger bar. The bracket may be discrete from the hanger bar but attached via tox clinching or a tab pass-through attachment.

A junction box having a sheathed cable retainer structure is disclosed. The junction box contains pry outs that cover openings at corners of the junction box wherein the pry outs are removed and a sheathed cable or like electrical wiring can pass therethrough. A strain relief bracket having segmented distal bends at opposite ends thereof engages the cable and under bias pushes the cable against an indent formed on a wall inside the junction box opposite the cable.

Ear muff with side mount

Earmuff with front mount

An earplug composed of a resilient polymeric material including a first hollow member having a closed end and an open end and with the closed end having a rounded cone shaped configuration. At least one flange member extending from the first hollow member and having a similiar cone shaped rounded configuration as the closed end of the hollow member but larger in diameter and located rearward of the closed end. A plug member for insertion into the open end of the first member and with the plug closing off and sealing the open end of the first member to form an air pocket immediately adjacent the closed end and the flange member. The plug member serving in combination with the rearward end of the first member as a handle for insertion of the earplug in an ear canal.

Headband for ear protection

A headband ear protector apparatus with break-away cord attachment including a pair of ear protectors, a resilient headband to form a band which positions the ear protectors to lie by the opposite sides of the head of a person. The headband is formed of a combination of harder and softer materials. The harder material is formed as a main support member for the ear protectors to extend between the ear protectors and provide resilience so the ear protectors will lie by the opposite sides of the head of the person. The main support member includes at least two regions having structure to receive the softer material. The softer material is received by the regions formed with openings having a particular size. A break-away cord attachment for the headband includes a flexible cord having a hard tip at each end of the cord, with the hard tips having a size larger than the particular size of the openings in the softer material to have each tip held in an opening by pressure and friction.
