Abstract: The present disclosure relates to prosthesis systems having trays and liners having an asymmetrical locking mechanism to bias the strength of the liner to resist loading forces and associated methods. The tray has a lateral groove disposed in an inner surface of a lateral circumferential portion of the tray and a medial groove disposed in an inner surface of a medial circumferential portion of the tray. The liner has an upper segment and a lower segment. The liner has a locking portion for lockingly engaging the tray that includes the lower segment. The locking portion has a lateral toe positioned generally diametrically opposite a plurality of resiliently deformable medial fingers defined therein. The liner and the tray are engageable in a lateral-to-medial direction so that the plurality of medial fingers can resiliently deform to engage the medial groove subsequent to engagement of the lateral toe within the lateral groove.

Abstract: Improvements in a reusable locating bracket for a recessed speaker or light bracket is disclosed. The bracket matches the hole diameter for a speaker of light. The bracket is installed prior to installation of drywall and is used as a trim guide. After installation of the drywall and cutting or trimming of the opening, the bracket is folded, bent, rotated or articulated where it can be removable through the trimmed opening in the drywall or sheet rock. The bracket has folding hinges for retaining side supports. The side supports are typically strips of cardboard, chip board or other material that provides a span from the bracket to studs, joists or beams. The folding hinges have teeth that grip the cardboard and can be opened to pull the cardboard through the retainer.

Abstract: Improvements in a fixture housing for recessed speaker or lighting that can be installed from one side of a wall or ceiling is disclosed. Once the ideal location is identified an installer uses a hole saw to cut an opening in the desired location. The fixture housing can then be pushed into the opening. The fixture housing for recessed speaker includes a plurality of engaging tabs that allows an installer to simply lift the speaker into the fixture housing for recessed speaker, and then turn the speaker within the fixture to lock the speaker within the fixture housing for recessed speaker. The securing tabs fold inward to clear the hole opening and then fold back out where the securing ears are brought down onto the back side of the opening to clamp the fixture to the wall or ceiling and secure the fixture.

Abstract: Improvements in a fixture housing with dog ears is disclosed that can be installed from one side of a wall or ceiling. This increases the ability of the installer to place the fixture in a desired location as opposed to using a location that provides the best access on stud or joists. Once the ideal location is identified the installer uses a saw to cut an opening in the desired location. The housing is pushed into the opening for installation without requiring access to the back of the wall, ceiling or floor. The fixture housing uses a plurality of spring loaded dogs that are operated from the visible wall or ceiling surface. It is also possible for the fixture to be removed by lifting the locking tabs and sliding securing ears where the entire fixture can then be pulled back through the open hole.
