Abstract: An X-type guide bar structure includes a lower rail mounted in a longitudinal direction at a lower side of a vehicle body, a lower slider rollably connected to the lower rail, a guide rail mounted on a door in the longitudinal direction of the vehicle body, first and second guide sliders movably connected to the guide rail, and first and second guide bars having guide paths in the longitudinal direction, wherein the first guide bar is rotatably connected to the lower slider and the second guide slider, the second guide bar is rotatably connected to the lower rail and the first guide slider, the first and second guide bars overlap in an X shape so that the guide paths face each other, and a guide pin is inserted into a central portion of the X shape.

Abstract: A vehicle sliding door mechanism is arranged to move a door from a door opening provided in a vehicle side body structure from a closed position to an open position. The sliding door mechanism comprises an upper slide rail and a lower slide rail fixed to the vehicle side body structure. An upper slider is associated with the upper rail and is movable along the upper rail, and a lower slider is associated with the lower rail and is movable along the lower rail. An upper link assembly operatively connected to the vehicle door and the upper slider, and a lower link assembly is operatively connected to the vehicle door and the lower slider. At least one link assembly of the upper link assembly and lower link assembly is configured to control a moment of force about a pivot axis while moving the vehicle door between the closed position and the open position.

Abstract: A sliding door mechanism includes an upper slide rail and a lower slide rail fixed to a vehicle side body structure. An upper slider is associated with the upper rail, and a lower slider is associated with the lower rail. An upper link includes a control arm pivotally connected to both the upper slider and a vehicle door. A lower link includes a control arm pivotally connected to both the lower slider and the vehicle door. A control mechanism is operatively associated with a selected one of the upper link and the lower link. The control mechanism includes a first control fixed to the vehicle side body structure and a second control fixed to the control arm of the selected link. Movement of the second control is based on predetermined structural constraints associated with the first control. The control mechanism controls rotation and translation of the upper and lower links.

Abstract: A hyperbaric oxygen chamber for treatment of large animals such as horses is disclosed. The chamber is large enough for a horse to fit inside and comfortably move around. A specially designed davit door, though quite heavy, is easily manipulated and may be used to corral the horse during ingress or egress, and is serviceable using fluorocarbon lubricants. The door, sidewalls, and floor of the hyperbaric chamber are coated with a static dissipative polyurethane material suitable for oxygen environments and may protect the horse from injury and prevent sparks. The flooring is specially designed to allow the horse to eliminate during treatment, and may be cleaned easily and thoroughly without disassembly. The control mechanisms of the hyperbaric chamber include electro-pneumatic controls, for avoiding a fire hazard.

Abstract: Disclosed herein is a panel movement system. The panel movement system includes top and bottom rails, top and bottom rail attachments, and a gear movement system. The top and bottom rails include threaded screw members along their lengths and first cog members rotatively coupled to the threaded screw members. The top and bottom rail attachments are movably attached to respective ones of the rails for lateral movement along lengths of the rails. Each rail attachment includes a rotatable second cog member engaged with the first cog member on respective ones of the rails. The gear movement synchronization system connects the rotatable second cog member of the top rail attachment to the rotatable second cog member of the bottom rail attachment such that the top and bottom rail attachments move along the rails in unison. The top and bottom rail attachments are adapted to have a panel connected therebetween.

Abstract: A high temperature industrial door having a flexible door plate with notches about the periphery thereof for receipt of swing bolts. The door plate includes interior insulation and is suspended from and hinged to a door frame using a davit assembly. In the closed position, the lower edge of the door extends below floor level. To open the door, the davit assembly allows the door to be lifted above floor level and moved to an open position, by pivoting of the davit assembly.
