Patent number: 10689213Abstract: Various example vehicle restraints for use at a loading dock for blocking and later releasing a vehicle's rear impact guard. In some examples, the vehicle restraint includes a hook-shaped barrier that rotates between a lowered position and a raised position. The barrier rotates up to block the rear impact guard and rotates down to release it. The barrier also translates or shifts forward and back between a retracted position and an extended position. The barrier shifts forward to relieve forward pressure that the vehicle might exert against the barrier just prior to releasing the rear impact guard.Type: GrantFiled: May 29, 2018Date of Patent: June 23, 2020Assignee: RITE-HITE HOLDING CORPORATIONInventors: Alan Mushynski, Leonard Kikstra, Matthew Sveum

Patent number: 10329817Abstract: Example insulated pliable door panels or curtains include various internal vapor barriers. The vapor barriers have a relatively high water vapor transmission rate that inhibits water vapor from permeating through the door panel. With such vapor barriers, outer sheets of the door panel can be made of polyurethane or other tough materials that might have an inadequate water vapor transmission rate. In some examples, the vapor barrier encircles or encloses a thermally insulating pad. In some examples, the door panel includes a sleeve or pocket that holds the vapor barrier in place. Some examples include means for draining water that might condense within the door panel.Type: GrantFiled: June 30, 2016Date of Patent: June 25, 2019Assignee: RITE-HITE HOLDING CORPORATIONInventor: Perry W.

Patent number: 10274216Abstract: 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.Type: GrantFiled: August 22, 2008Date of Patent: April 30, 2019Assignee: RITE-HITE HOLDING CORPORATIONInventors: Jeffrey Klopfenstein, Kevin J.
