An air diffuser for use at a ventilation outlet of an HVAC system. The air diffuser comprises a base platform having an opening plenum formed from injection-molded plastic, the base platform including a collar for attachment to the outlet, the plenum defined by a perimeter rim, the edges of the rim lying substantially within a first common plane, at least one first diffuser plate positioned over the plenum, the first diffuser plate formed from injection-molded plastic and having edges lying substantially within a second common plane, and a plurality of stems integrally molded with one or more of the first diffuser plate and the base, the stems configured to secure the first diffuser plate to the base platform, each of the stems having a first end sized to fit within a complimentary female receptacle formed in one of the first diffuser plate and the base platform, the stems being formed via injection molding with one of the first diffuser plate and the base platform.

Injection molded HVAC diffuser assembly

A sign assembly includes a panel and a base. The base is configured to be attached to the panel via a resilient member. The bottom surface of the base defines a pair of cavities. The cavities are positioned substantially adjacent to a forward edge of the bottom surface. A pair of wheel assemblies is secured within respective cavities on the bottom surface. Each wheel assembly includes a housing that houses an axle and wheel.

Sign assembly

A sign assembly includes a base, a pair of spring members, and a panel. The spring members include a resilient portion that includes attachment means at a first end to enable attachment of the spring member to the base. The spring members also include a generally straight rod that extends from a second end of the resilient portion. The panel defines a pair of openings at a lower edge configured to slidably receive the rod of the spring members. The amount by which the rod slides into the panel is configured to secure the panel in an upright position.
