Abstract: A device including a housing having an access opening, a swing arm mounted to the housing and configured to be selectively pivoted toward and away from the access opening, and a closure captured by the swing arm. The closure can be configured to be selectively moved in a substantially vertical motion relative to the swing arm between a retracted position and an inserted position at least partially in the access opening and can have locking features for cooperating with engagement features in the device to move the closure into a closed and sealed configuration.

Abstract: Disclosed is an aluminum trailer bunk having a support housing, a base plate, an aluminum rail, and a protective covering positioned over the aluminum rail. Further disclosed is an aluminum replacement rail for a trailer, including an aluminum rail having a bottom plate and a support member, a plurality of L-brackets, and a protective covering placed over said support member.

Abstract: A vision test apparatus includes a viewing assembly connected to a chassis wherein the viewing assembly creates an optical path between an image display and at least one front lens. A near/far assembly includes a secondary lens selectively operable with the front lens to create virtual visual distances. An optional transparent panel intersects the optical path and operates at least partially obscure the image display so that the vision testing apparatus has a means to isolate a portion of the image display. A lifting mechanism is operable to raise or lower the viewing assembly for patients of various heights. The viewing apparatus is also rotatable independently of said chassis to present natural lines of sight to a patient during near and far testing.
