## Background
CROSS-REFERENCE TO RELATED APPLICATION(S)
This application claims the benefit of US Provisional Patent Application Ser. No. 61/893,515, filed Oct. 21, 2013, the entirety of which is hereby incorporated herein by reference.


FIELD OF THE INVENTION
The present invention relates to air ventilation systems and, more specifically, to an attachment to an air register for directing an air jet to a desired location.
DESCRIPTION OF THE RELATED ART
Typical residential air ventilation systems include air ducts that transport air from a heating and cooling system to air registers located in different rooms throughout a house. Some registers are relatively close to the heating and cooling system, whereas other registers can be much farther away from the heating and cooling system. With some systems, there can be a substantial air pressure drop at the more distant registers. This can result in less air being delivered to inhabitants of distant rooms.
Existing systems used to alleviate discomfort in such distant rooms typically involve boosting airflow through a duct with a fan disposed in a register. Such systems usually require an electrical connection, which is frequently manifested as an electrical cord that is plugged into a wall outlet. Such systems have the disadvantages of being unsightly and being limited in range by the length of the electrical cord. Also, these systems often must be installed by removing an existing register and replacing it with a booster system.
Even in rooms that are closer to the heating and cooling unit, some users desire enhanced airflow. For example, people experiencing hot flashes often prefer air flow directed at a specific location.
Therefore, there is a need for a device that directs airflow from a register to a specific location.
SUMMARY OF THE INVENTION
The disadvantages of the prior art are overcome by the present invention which, in one aspect, is a directional air jet system for directing air from a vent register that includes a body frame having a foot surface and a shape configured to cover substantially the vent register. The body frame defines a cavity in fluid communication with the vent register. The cavity opens to a circular hole passing therethrough. A frustoconical member is disposed in the circular hole and is engaged with the body portion. The frustoconical member defines a circular top opening and an elliptical bottom opening. The frustoconical member is configured to rotate with in the circular hole. A ball nozzle is disposed within the elliptical bottom opening and engaged with the frustoconical member. The ball nozzle is configured to rotate relative to the frustoconical member. The ball nozzle defines a nozzle opening that is in fluid communication with the vent register through the circular hole, the circular top opening and the elliptical bottom opening, so that air passing through the nozzle opening forms a jet that flows in a selected direction. At least one magnet is affixed to the foot surface and is configured to attach the directional air jet system to the vent register.
In another aspect, the invention is a directional air jet system for directing air from an air vent that includes a body frame. The body frame has a peripheral wall and a lateral surface extending upwardly from the peripheral wall. The peripheral wall and the lateral surface define a cavity therein that opens to a hole defined by the lateral surface. The peripheral wall terminates in a foot edge that defines an open base opposite from the lateral surface that is in fluid communication with the cavity and that is configured to overlay the air vent. A plurality of pedestals is affixed to the body frame and is disposed inside the cavity. Each of the plurality of pedestals has a pedestal surface that is spaced apart by a predetermined distance from a plane defined by the foot edge. A plurality of magnets is each affixed to a different one of the pedestal surfaces and has a thickness corresponding to the predetermined thickness. The plurality of magnets is configured to removably couple the body frame to the air vent. The plurality of magnets has a distribution and dimensions so as to be configured to couple the body frame to a variety of different air vent sizes. A turret extends outwardly from the hole defined by the lateral surface and is configured to rotate about a first axis. A ball nozzle is pivotally fit into the turret and defines a bottom opening that is in fluid communication with the cavity through the turret. The ball nozzle is configured to rotate about a second axis that is transverse to the first axis so as to be configured to direct air from the air vent as an air jet in a user-selected direction.
In another aspect, the invention is a peripheral ledge extending inwardly from the foot edge of the peripheral wall and configured to deflect air inwardly toward the cavity.
These and other aspects of the invention will become apparent from the following description of the preferred embodiments taken in conjunction with the following drawings. As would be obvious to one skilled in the art, many variations and modifications of the invention may be effected without departing from the spirit and scope of the novel concepts of the disclosure.

DETAILED DESCRIPTION OF THE INVENTION
A preferred embodiment of the invention is now described in detail. Referring to the drawings, like numbers indicate like parts throughout the views. Unless otherwise specifically indicated in the disclosure that follows, the drawings are not necessarily drawn to scale. As used in the description herein and throughout the claims, the following terms take the meanings explicitly associated herein, unless the context clearly dictates otherwise: the meaning of “a,” “an,” and “the” includes plural reference, the meaning of “in” includes “in” and “on.”
As shown in FIGS. 1A-1D and 2-5, one embodiment is a system 100 for directing a jet 20 of air from a vent register 14 associated with duct 12 from a heating and cooling system. Typically, the vent register 14 is attached to a wall, a ceiling 10 or a floor of a room and the system 100 overlays the vent register 14.
The directional air jet system 100 includes a body frame 110 having a foot edge 111 that is shaped so that it covers the vent register 14. Flat magnets 160 are affixed to the body frame 110 and are used to affix the system 100 against the vent register 14. (Other methods of affixing the system 100 to the vent register 14 may also be used, including: two-sided tape, fasteners, etc.) The body frame 110 includes a peripheral wall 132 and a lateral surface 130 extending from the peripheral wall 132. The peripheral wall 132 and the lateral surface 130 define the cavity 113. The foot edge 111 defines an open base opposite from the lateral surface 130 that is in fluid communication with the cavity 113 and that is configured to overlay the air vent 14.
The body frame 110 defines a cavity 113 in fluid communication with the vent register 14 (air flow from the duct 12 through the register 14 and the system is shown with broken lines in FIG. 2). The cavity 113 opens to a circular hole 150 passing therethrough. A frustoconical turret member 120 is disposed in the circular hole 150, is engaged with the body frame 110 and is configured to rotate within the hole 150 (by 360° in one embodiment). The frustoconical member 120 defines a circular top opening 121 and an elliptical bottom opening 122, which is on a plane that is transverse to the plane of the circular top opening. A ball nozzle 124 is disposed in and engaged with the elliptical bottom opening 122 so as to be able to rotate transversely with respect to the frustoconical member 120. In one embodiment, the ball nozzle 124 includes oppositely disposed pins 162 that fit into pin joists 160 defined by the frustoconical member 120 at pivot points so that the ball nozzle 124 can rotate by pivoting. The boll nozzle 124 pivots along an axis that is transverse to the rotational axis of the turret 120, thereby allowing the system 100 to direct air in almost any user selected direction from the vent 14. The ball nozzle defines a nozzle opening 128 that is in fluid communication with the vent register 14 and a bottom opening 128 that forms air passing through the nozzle opening 128 into a jet 20 that flows in a direction desired by the user.
In one embodiment, the body frame 110 defines a plurality of pedestals 154, affixed to the body frame and disposed inside the cavity 113. Each of the pedestals 154 has a pedestal surface 156 that is spaced apart from a plane defined by the foot edge 111 by a distance corresponding to the width of the magnets 160, so that the magnets 160 are able to engage the vent 14 when the system 100 is placed against the vent 14. As shown specifically in FIG. 3, the magnets 160 (which may be elongated rectangular in shape) are distributed so that they can couple the body frame 110 to overlay a variety of different air vent sizes 22a-22d. As shown in FIG. 4, the pedestals 154 can be formed as indentations 140 in the body frame 110 that provide a gripping surface that allows the user to remove the system 100 from the vent at will.
In one embodiment, the body frame 110, the frustoconical member 120 and the ball nozzle 124 are injection molded and made of acrylonitrile butadiene styrene (ABS). As will be readily appreciated by those of skill in the art, these elements may also be made from many other materials, including other plastics and metals and made through other processes.
In one embodiment, a peripheral ledge 162 can extend inwardly from the foot edge 111 of the peripheral wall 132. The ledge 162 deflect air inwardly toward the cavity 113. In one embodiment, the ledge 162 can be a weather stripping gasket disposed peripherally about the inside of the foot edge 111. In another embodiment, it can be a rubber band that is stretched about the foot edge 111 so as to have an edge extending into the cavity 113.
A shown in FIG. 5, directional air jet systems 100 can be placed on several different vent registers in a room 30. The user 32 can then adjust each system to direct air to a specific desired location.
One embodiment is an accessory to any existing steel floor, wall, or ceiling register vent. With its one-size-fits all design, it magnetically mounts to the face of a vent. Self-powered, without the use of batteries or electric, it strictly utilizes the exiting thermodynamics of the ambient air pressure at any such vent, compressing the existing outbound air into a chamber, and forcing it out as a jet stream with enough force to move warm or cool air across a room. The multi-directional nozzle permits the user the ability to direct and control the air to where it best fits their needs.
The above described embodiments, while including the preferred embodiment and the best mode of the invention known to the inventor at the time of filing, are given as illustrative examples only. It will be readily appreciated that many deviations may be made from the specific embodiments disclosed in this specification without departing from the spirit and scope of the invention. Accordingly, the scope of the invention is to be determined by the claims below rather than being limited to the specifically described embodiments above.
