Abstract: An air circulator for a vehicle is provided. The air circulator includes a blower case and a connection duct that is connected to an outlet of the blower case. The connector duct includes a first path and a second path that are divided by a separation plate. Additionally, a filter is mounted in the outlet of the blower case and an inlet door is mounted in the blower case to selectively allow air to be blown into the first path and/or the second path.

Abstract: A barrier door for a protective enclosure includes a lower section and an upper section operably coupled with the lower section, and a ventilation system disposed within the lower section. The ventilation system includes one or more blowers and a plenum. The ventilation system is configured to direct air one or more of into or out of the protective enclosure.

Abstract: A register includes an operation knob which is slidably assembled to a selected one of front horizontal blades and which is connected to a selected one of rear vertical blades via a connection mechanism. The connection mechanism includes a connection pillar portion formed integrally with an intermediate portion of the selected vertical blade, the connection pillar portion having a generally circular cross section and being located at a position deviating from a rotation axis of the selected rear vertical blade, and a pair of connection arm portions extending rearward from the rear end of the operation knob with a predetermined space formed therebetween. The operation knob is connected to the selected vertical blade in a state where the connection pillar portion is rotatably inserted into an engagement groove between the connection arm portions.

Abstract: An actuator controller includes an actuator body to be driven in a predetermined driven range, an actuator driving unit; and a controller body for controlling the driven position of the actuator body. The controller body includes an instructing signal outputting zone configured to outputting a position instructing signal for instructing the driven position of the actuator body according to a bid, excluding arbitrary two bits among the predetermined bit counts, an normal direction forcedly driving signal for instructing a normal direction forcedly driving to drive the actuator body in a predetermined direction with the one of the arbitrary two bits, and a reverse direction forcedly driving signal for instructing a reverse direction forcedly driving to drive the actuator body in a direction reverse to the predetermined direction with the other arbitrary bit.

Abstract: A vehicular air conditioning system of the present invention comprises an air conditioning unit which forms an air flow, a first vent 8 through which the air flow formed by the air conditioning unit is blown out toward a passenger, a second vent through which the air flow formed by the air conditioning unit is blown out in an upper direction of the vehicle, an air flow blowout switching unit which switches between blowout from the first vent, and blowout from the second vent at predetermined intervals. The air flow blowout switching unit includes a door unit which closes one of the first and the second vents and opens the other vent, and a control unit which controls the closed state and the opened state of the door unit.

Abstract: A grill assembly comprising an anchor member adapted to fit in a duct around the periphery of a duct opening. Tie members may be slidably attached to the anchor member so that it projects outwardly from the anchor member for receiving a frame. A damper and cover may be subsequently attached to the frame.

Abstract: A cover assembly for a roof mounted air conditioner unit which allows an increased output air volume to flow from a roof mounted air conditioner into a cooling volume; the assembly comprises a cover, return air grills, side diffuser assemblies, and a register having frame, directional control louvers, volume control louvers, a throttle and mounting screws; the register is substantially in alignment with the output blower of a roof mounted air conditioner and sized to allow a maximum output air volume to flow into the cooling volume. The register's volume control louvers and directional control louvers control the amount of air passing through the register and the direction of air flow respectively. Additionally, a method for retro-fitting existing covers with a register aligned with the output blower of a roof mounted air conditioner thereby producing the same effect of the improved cover assembly is shown.
