An air register handle (10) for mounting in an air register arrangement (12) to adjust the volume and/or direction of air flow through the register (12). The handle (10) includes a bracket (22) adapted to extend forwardly of a front plate (40) of the register (12). The bracket (22) is integral with a straight portion (20) adapted to extend rearwardly through a slot (44) on one side of the front plate (40). Handle tabs (24) extend from the straight portion (20) in a plane skewed relative to the plane of the straight portion (20). An arcuate flat portion (26) located rearwardly of the straight portion (20) comprises two arcuate arms (29) forming a slot (28) opening toward the rear of the handle (10). The slot (28) is adapted to receive a pintle (56) connected to a link (54) which interconnects a set of adjustable louvers (52).

A supply and return air plenum unit for duct air-conditioning systems includes a return air inlet and a supply air outlet defined in a case in vertical juxtaposition, the supply air outlet having an opening located at a front lower corner of the case. A blow-off grill is disposed in the opening of the supply air outlet and is angularly moved by an actuator for varying the direction of supply air within a range between the horizontal and the vertical.

Disclosed herein is a decumbent type petunia plant having long stems. The plant has abundant branching and a great profusion of blooms, and the whole bush remains in bloom for a considerable period of time. The flowers are single and relatively small and the petals have a metallic luster and a strong reddish purple color with dark reddish purple lines radiating from a moderate purple center portion. The plant is highly resistant to rain, heat, and drought.

An automatic temperature responsive ventilator including a housing having side walls defining an air passageway and an openwork grid across the passageway. At least one shutter is mounted within the housing, with one end of one shutter element being associated with a bimetallic spring, the inner end of which is received within an opening in one housing side wall. An outer end of the spring is secured to the shutter. A size-adjustable installation device includes a threaded portion which engages a threaded opening in the housing or in a member held non-rotatable relative to the housing. One end of the threaded portion is integral with a non-threaded distal portion having a diameter less than the diameter of the threaded portion and carrying thereon the small diameter end of a conically shaped compression spring. Variations in ambient temperature cause the shutter element to open and close automatically.

An electric fan heater includes a stationary housing and a louver blade assembly having a plurality of oscillating louver blades located forwardly in the housing for providing multidirectional hot air flow from the heater. The heater also includes a drive system for the louver blade assembly with the drive system comprising lightweight plastic drive gears and a small rubber drive belt located rearwardly in the housing as well as a lightweight plastic connecting shaft extending forwardly from the drive gears to the louver blade assembly. The electric heating element for providing hot air from the heater is positioned between the louver blade assembly and the plastic drive gears. The gears and connecting shaft are located in the housing laterally outwardly from the heating element to avoid direct exposure to the heat therefrom. A common motor is used to operate both the heater and the fan blade which is positioned to move the hot air forwardly from the heating element out past the louver blades and away from the drive gears and to draw cooling air to the drive gears, connecting shaft and rubber drive belt which is further protected by a heat shield between the heating element and the drive belt.

An automatic temperature responsive ventilator including a housing having side walls defining an air passageway and an openwork grid across the passageway. At least one shutter is mounted within the housing, with one end of one shutter element being associated with a bimetallic spring that is received within an opening in one housing side wall. An inner end of the spring is secured to a rod that is attached to the shutter. A setting plug is received in the opening in the side wall to hold the spring in place and to preset the tension in the spring which drives the shutter between an open and closed position relative to the passageway. Variations in ambinet temperature cause the shutter element to open and close automatically.

A ventilator grill comprises an outer frame made of synthetic resin having an inlet opening and outlet opening, at least one stationary vane extending across an interior of the outer frame, a plurality of through holes provided in each half of the outer frame, arcuate recess provided in an end face of the respective stationary vane, which opposes the inlet opening of the outer frame, and which has a circular arc, and at least one movable vane extending across the stationary vane, which is provided at opposite sides thereof in opposing side walls of the halves of the outer frame with journal shafts received within the through holes for permitting the movable vane to swing about an axis of swing extending through a center of the circular arc of the arcuate recess, and which is provided at one end portion thereof toward the inlet opening of the outer frame with a portion which is in sliding contact with the arcuate recess.
摘要:
Within the vent system of an air conditioning unit or the heating system at least one flap is pivotably mounted such as to be moveable between a closed position blocking flow through the conditioned air vent, and an open position allowing conditioned air to pass through the vent and into one or more rooms to be serviced by the conditioned air. One or more stops are provided to cease pivotable movement of the flap when the open position is reached. Preferably more than one flap is utilized. Preferably gravity is utilized to bias the flap into the closed position so that when the heating or air conditioning blower is turned off the flap will return to the closed position. The flap is also moveable manually between the open and closed positions, thereby a room or rooms which are not to be heated or cooled may be blocked off from the air conditioning or heating system by the manual closing of the flap.
摘要:
A wind direction adjusting mechanism for an air conditioner which has an air diffuser barrel supported to a rotational shaft to rotate in elevational or lateral directions in a bezel of a side ventilator, longitudinal or lateral blades pivotally secured in lateral or longitudinal directions in the barrel, a cam rotatably engaged with the rotational shaft, a rod engaged with the cam for operating to rotate the longitudinal or lateral blades, rotary drive means coupled with said cam, and a frictional clutch for producing a slip by a resistance of a predetermined value to couple the cam with the drive shaft. Thus, the adjusting mechanism can separately rotate the air diffusing barrel in a bezel of a side ventilator and the longitudinal or lateral blade in the barrel by a simple drive mechanism, protect the drive mechanism by the slip of the clutch when an unreasonable force is acted to the air diffuser barrel side, be associated in large degree of freedoms of designing in an instrument panel to improve the design in the compartment and provide the large defrosting function of the side window glass.

An air sweep mechanism in the discharge opening of a room air conditioner is provided with an operator level to select a desired position of fixed orientation for the vanes. When the vanes subsequently arrive at the position so selected, the air sweep drive mechanism is automatically stopped to leave the vanes in that fixed orientation.
