  • Patent number: 11231189
    Abstract: An under-floor HVAC system for a building includes a pliable air duct lying upon a subfloor. A matrix of pedestals resting upon and extending upward from the subfloor supports a set of floor panels, which thus creates a plenum between the subfloor and the set of floor panels. The air duct extends through the plenum to convey conditioned air from a supply air duct to a series of registers in the floor panels. The registers disperse the conditioned air to a room or area just above the panels. To help keep the air duct from repeatedly extending, retracting, and otherwise sliding freely along the subfloor in response to changes in air duct pressure, the air duct is held taut by anchoring a distal downstream end of the duct to one or more of the floor-supporting pedestals. Various air duct configurations can be assembled from a predefined assortment of duct components.

  • Patent number: 11077895
    Abstract: Example portable trailer stands for supporting parked trailers are disclosed herein. Some example portable trailer stands disclosed herein comprise two telescopic posts supporting a generally horizontal beam. Some examples include spring-loaded retractable wheels for selectively installing and removing the trailer stand from underneath a trailer left parked on a driveway. After being positioned under the trailer, the posts extend to lift the beam solidly up against the underside of the trailer. To accommodate conditions where the driveway is not parallel to the trailer's underside, some example posts can be lengthened independently and have angular play that allows the beam to tilt. In some examples, the horizontal axle of the trailer stand wheels is perpendicular to the beam so that the trailer stand can be readily installed from either the front or side of the trailer. Some examples have a kingpin-receiving groove in the beam or have some other kingpin-receiving feature.
