An air vent assembly may include a housing configured to allow air to pass therethrough, a slit assembly disposed inside the housing and configured to control a flow direction of the air, and a knob movably connected to the slit assembly to move the slit assembly, wherein the slit assembly includes: an upper inlet plate connected to the housing, the upper inlet plate being movable along the internal surface of the housing, a lower inlet plate forming an inlet slit from the upper inlet plate and disposed inside the housing, the lower inlet plate being connected to the housing and movable along the internal surface of the housing, and an outlet plate, wherein a first side of the outlet plate is pivotally coupled to the upper inlet plate and the lower inlet plate to be movable together with the upper inlet plate and the lower inlet plate and the other side is pivotally coupled in the housing.

A ceiling type air conditioner includes a housing having an inlet and an outlet, a heat exchanger provided inside the housing to exchange heat with air suctioned through the inlet, a blower fan configured to cause the air having heat exchanged with the heat exchanger to flow such that the air having heat exchanged is discharged through the outlet, and a blade unit configured to guide the air discharged to the outlet. The blade unit includes a main blade, a sub-blade, and a guide link provided to guide a movement of the sub-blade.

A cam assembly for selectively contacting an end-of-stroke damper position switch. The cam assembly includes a first cam that is rotatable about a first axis, and a position lever that is connected to and rotates with the cam assembly. The position lever is configured to be connected to an opening and closing mechanism of the damper and the cam assembly is adjustable to contact a first end-of-stroke damper position switch at the end-of-stroke of the opening and closing mechanism of the damper regardless of the position of the lever.

A device for manipulating an actuator (1) of an air vent (2), wherein, for generating as required an adjustment movement acting on the actuator (1), the device has a preferably manually actuable actuating element (3) and a drive mechanism (6) with a motor drive (7). The drive mechanism (6) is assigned a resetting mechanism which is designed to make an adjustment movement, brought about previously by the drive (7), of the actuator (1) relative to the housing (10) of the air vent (2) reversible again, if required, such that the actuator (1) is then again in a position relative to the housing (10) of the air vent (2) that was set previously by actuation of the actuating element (3).

A ventilation system including a housing, with an inlet end into which air is directed, and an outlet end at which the air exits. The housing includes an inlet portion at the inlet end, and first and second channels downstream from the inlet portion. The ventilation system includes an air flow guide element pivotable between a first position, in which a first major portion of the air flowing into the inlet end is directed into the first channel and a first minor portion of the air flow is directed into the second channel, and a second position, in which a second major portion of the air flowing into the inlet end is directed into the second channel and a second minor portion of the air flow is directed into the first channel.

An air-conditioning register includes: a downstream fin; and an upstream fin. The downstream fin and the upstream fin are provided in a ventilation passage which allows air-conditioning air to flow. The downstream fin is rotatable around a center line of a first rotation shaft. The upstream fin is rotatable around a center line of a second rotation shaft further on an upstream side than the downstream fin in the ventilation passage. The second rotation shaft extends in a direction different from that of the first rotation shaft. The downstream fin is slidable in a center line direction of the first rotation shaft and has a driving unit which presses the upstream fin in a slide movement direction as the downstream fin slides.

Air vent for a vehicle, including a housing with an inlet opening and an outlet opening, and an air duct for air flowing from the inlet opening to the outlet opening in a main flow direction. A slat assembly is arranged in the air duct and has a plurality of air-guiding slats that are pivotable together with respect to the main flow direction, and designed to divert the air flow from the main flow direction in an open position of the slat assembly and to interrupt the air flow in a closed position of the slat assembly. The air-guiding slats, in the closed position, are braced relative to one another and each of them takes up its end position, and at least some of the air-guiding slats reach their respective end position in succession during an adjustment of the slat assembly from the open position to the closed position.

The invention is directed to a handle assembly for rotating a pivot rod attached to a damper within ductwork, for the purpose of controlling the flow of conditioned air therethrough. In particular, the present invention provides a pre-assembled portion of the required parts, thereby reducing the number of steps required for final assembly of the damper handle to the pivot rod, resulting in a significant time savings.

A motor-driven air vent device for a vehicle is provided. The motor-driven air vent device connects a horizontal wing of an air vent to an output shaft of a driving motor through a link structure and rotatably operates the driving motor in the forward direction or the reverse direction by a touch type switch operation. Accordingly, the vertical angular rotation operation for the horizontal wing is automatically performed by the operation of the link structure delivering the torque of the driving motor.

An example an adjustable bracket and an damper system usable with the adjustable bracket assembly for transmitting an actuation force from an actuator to a plurality of damper assemblies. The adjustable bracket assembly may include a shaft extending along and configured to rotate about a first axis in response to an output from the actuator, a first output lever configured to transmit a rotational force of the shaft to a first damper assembly, and a second output lever configured to transmit the rotational force of the shaft to a second damper assembly.
