Portable Ventillation System
Technical Field
This invention relates generally to devices useful for providing ventilation by circulating ambient air. More particularly, it relates to portable devices that are usefixl for circulating the air surrounding a person resting on a substantially flat surface, sucli as a bed. Background
It is fairly common knowledge that on average, people spend about 1/3 of their lives sleeping. However, there are many people whose sleeping activity does not fall within the average, and of these people a substantial proportion experience one or more common sleeping disorders. While a detailed discussion of the number and types of sleep disorders is beyond this specification, it is nevertheless worthy of mention that most of the people who experience sleep disorders typically achieve less sleep than they generally desire. Sleep deprivation is known to alter cerebral behavior, as shown by hundreds of readily-available studies in the field of psychology, including MRI scans of the temporal lobe of the cerebral cortex of sleep- deprived persons versus persons well rested during verbal learning tests. (Nature magazine, 2/10/2000 issue by author Sean Drummond, et al). Sleep deprivation has been shown to correlate with increased rates of suicide, increased divorce rates, and increased mental stress, which can in many cases set the foreground for the development of more serious chronic disorders. Therefore, it is clear that successfully assisting a person who suffers from a sleep disorder in restoring their body's natural sleeping patterns is an achievement of multi-faceted benefit.
There are a many causes of the various known sleep disorders. Of these causes the physical comfort of the person attempting to sleep or rest is paramount, for if a person's ambient surroundings are not conducive to their personal comfort, sleep can become extremely difficult to achieve, if at all. One factor in the person's environment that has a bearing on their ability to achieve sleep is the ambient temperature. If the temperature of the surroundings of a person is either too hot or too cold, restful sleep may be impossible. Of particular concern is the case where the surroundings are too hot, because in such cases the body's ability to control its internal temperature may be effected to the point where the body begins to sweat, and it is nearly impossible to achieve restful sleep while sweating. Thus, maintaining the ambient temperature at a level which is conducive to sleep is a key to enabling a person to sleep.
Means for controlling the ambient temperature in a person's surroundings are known to include the provision of "air conditioning" in which an air conditioner utilizing the principles of Joule-Thomson cooling is employed to extract heat from a volume of air, such as a bedroom. While air conditioners are highly effective at coarsely controlling the temperature in a room, the customary preference for persons to sleep beneath one or more bedsheets, covers, blankets, etc. coupled with the body's tendency to liberate heat during its normal operation translates to the well-known situation in which the person resting beneath the sheets cannot get comfortable because they are too hot, which is compounded by the proposition that if they remove the covers or sheets from themselves then they become too cold. Owing to variance between selected individual human subjects' metabolism, genetics, etc. the method used in the fine tuning control of one's body temperature becomes a matter of personal taste or preference, and many individuals have typically been observed to develop
their own personal habits of effecting such fine tuning, such as sleeping with more or less clothing, permitting part of the body to be exposed to the open air, etc. m spite of these efforts, however, perfect control of the temperature of ambient surroundings of persons desiring to sleep has been fleeting. This fact is evidenced by the myriad of schemes and contrivances provided by workers in the prior art for effecting thermal control over a bed or region in which a person normally rests for sleep, which are known in the art, and include those cited in the priority patent application document in this case on file with the US Patent and Trademark Office, which are herein incorporated by reference thereto in their entirety. While each of the prior art devices and methods achieve to a greater or less extent their desired objectives, they are nevertheless not without features which have heretofore prevented their widespread adoption by large numbers of people. One of the main factors is believed to be the relative complexity of the prior art devices, with their attendant high cost, tedium in operation, and cumbersomeness in appearance and difficulty in retrofitting existing furniture, beds, and the like. Tlius, it is clear that if a device were available which enabled a high level of control of the temperature of a person's body during sleep and which device were capable of being readily retrofitted to existing furniture, beds, and the like, that a large number of persons with sleep disorders could find relief from employment of such a device. If such a device were of such simplistic design that it could be manufactured and sold at a cost which is accessible to the predominant majority of persons, such would undoubtedly lead to its adoption. In addition, if such a device were small and portable, so that a user could easily stow it when not in use or transport it conveniently when traveling on the road or when merely switching rooms, such a feature would make adoption of such a device more attractive still. The present invention fulfills all of these needs in the
marketplace, in addition to others as one of ordinary skill will come to appreciate by further consideration and understanding of the contents and implications of this specification and the claims appended hereto.
Summary of the Invention The present invention provides a device useful for providing a moving current of ventilating air which comprises: a) a base portion having a hollow interior portion which itself further comprises: i) at least one inlet opening through which air may be admitted, and ii) an exit opening through which air may exit the liollow interior portion; b) an air conduit channel means having an inlet end portion and an outlet end portion; wherein the inlet end portion of the air conduit channel is in effective fluid communication with the exit opening of the base portion; c) at least one fan means disposed between the inlet opening in the base portion and the outlet end portion of the air conduit channel for causing ambient air to flow from the inlet opening of the base portion to the outlet end portion of the air conduit channel; and c) a support bar means adjustably attached to the air conduit channel.

Detailed Description
Referring to the drawings and initially to FIG. IA., there is shown a front perspective view of a device 10 according to one form of the invention which is shown as comprising a base portion 3 having an interior volume, an inlet opening 5 through which ambient air may be admitted, and an exit opening 7 through which the admitted ambient air may be expelled from the interior of the base portion under the power of one or more fan means which are disposed within the interior volume of the base portion. To the exit opening 7 of the base portion 3, there is attached the inlet end portion 11 of an air conduit channel means 9, through which air that has been discharged from the exit opening 7 of the base portion may enter the conduit channel 9 and under the force of the fan means is conveyed to the outlet end portion 13 of the conduit channel 9. Thus, during the normal operation of a device according to one form of the invention, the fan means thus causes air to he admitted to the inlet opening 5 and to be forced to exit conduit channel 9 at its outlet end portion 13. Also shown in FIG. IA is the electrical power cord 29 used to supply electrical power to trie fan means.
Some details of a base portion 3 useful in constructing a device according to this invention are shown in FIG. IB, in which the base portion 3 is seen to comprise a plurality of fan means 53 disposed at the inlet opening of the base portion, and a rectangularly-shaped opening which serves as the exit opening 7 of the base portion 3. During operation of the fan means 53, which preferably comprises one or more conventional fans operated by a DC or AC electric motor, air is drawn into the hollow interior portion of the base portion 3 and expelled out of the opening 7 and into the air conduit channel means as shown and described for FIG. IA.
The base portion 3 has a dual purpose in a general sense, which on the one hand is to serve as a housing for the fan means 53, that is, the fan means are disposed within the hollow interior volume of the base portion such tlxat their motion draws air into the base portion through the inlet opening(s) 5, and the fan means 53 by its (their) action expels the air through the exit opening 7 of the base portion 3. Since the fan means in one form of the invention are conventional fans with a motor and a blade, their being housed within the base portion prevents the blades motion from being inhibited such as by being struck, touched by a hand, etc., i.e., the base portion acts as a shroud for the fan means. The base portion 3 also serves as the support for the device 10 as a whole, and in many employments of the device it will rest with its base on a horizontal floor or a room in a dwelling or other area. Thus, while the base portion 3 may have outer walls or surfaces which cause it to exist in the configuration of any geometric solid, it preferably comprises a flat bottom portion suitable for enabling the device 10 to rest on a flat surface with the air conduit channel means 9 being disposed so that air is discharged from it in a substantially- vertical orientation. Trie base portion is in one preferred form of the invention comprised of a plurality of pieces of sheet stock, such as plywood or polyolefin slab stock about 1/8 inch thick, or any functionally-equivalent material of construction. The base portion 3 is preferably comprised of a thermoplastic polyolefin and is inj ection molded as a single piece having an interior volume of substantially the same shape as defined by its exterior walls, as it may be thought of as being basically a box.
According to a preferred form of the invention, the conduit channel means 9 is configured in the form of a rectangular solid with a hollow interior portion, which, when standing alone has its two end portions open to the ambient surroundings The purpose for this shape includes provision for convenient aligned mating of the exit
opening 7 of the base portion 3 with the open inlet end portion 11 of the air conduit channel means 9 when the exit opening 7 of the base portion 3 is substantially rectangularly-shaped as in a preferred form of the invention. Such configuration of the air channel means also provides a relatively wide zone of air exiting the outlet end portion 13 of the air conduit channel 9 when the device is in operation, as the width dimension of the air channel means 9 is about 12 inches in one preferred form of the invention. The air conduit channel means may be attached to the exit opening 7 of the base portion 3 by conventional means, such as glues, adriesives and the like, and is preferably itself comprised of sheet stock of wood or thermoplastic polyolefin. The base portion 3 and the air conduit channel means 9 may according to one preferred form of the invention be a single construction, prepared by an injection molding process. An air conduit channel means 9 according to one form of the invention is depicted in FIG. 1C. having a rectangularly- shaped inlet portion 11 through which air may pass and be discharged at the outlet end portion 13. FIG. 2 shows a rear perspective view of a device 10 according to one form of the invention and the relationship of the various elements of the invention to one another, including the base portion 3, exit opening 7 of the base portion, inlet end portion 11 of the air conduit channel means 9, outlet end portion 13 of the air conduit channel means 9 and the power cord 29. FIG. 3 shows a left side perspective view of a device according to one form of the invention and the relationship of the locations of various elements of the invention including the base portion 3, air conduit channel means 9, outlet end portion 13 of the air conduit channel means 9, and power cord 29.

invention including the base portion 3, air conduit channel means 9, outlet end portion 13 of the air conduit channel means 9, power cord 29, rheostat 31 and transformer 33. The rheostat 31 is a conventional rheostat or device of equivalent function which serves to controllably regulate the voltage to the fan means so as to permit adjustment of the volume of air exiting the outlet end portion 13 of the air conduit channel means 9 during operation of the device 10.
FIG. 5 shows a perspective view of a support bar means 17 useful on a device according to one form of the invention. The support bar means 17 is a thin piece of flat slab stock or extruded stock having an arcuate, c-shaped, or crescent-shaped cross section, which is caused to be disposed directly in the flow of air which exits the outlet end portion 13 of the air conduit means of the invention, so as to re-direct the flow of air which impinges on it. When the cross section of the support bar means 17 is arcuate, it is preferred that it traces out approximately a 90° arc. The support bar means 17 is attached by means of the right support arm 19 and left support arm 21 to the air conduit channel means 9, preferably by attachment of the support bars to the edges of the air conduit channel by means of conventional fasteners which may include a hook-and-loop type fastening means such as VELCRO® fastening means, λvith one portion of the fastening means 55 disposed on the inside of the support arms and the complementary counterpart of the fastening means disposed on the external surfaces of the air conduit channel means 9.

FIG. 18 shows a bed having a device according to the invention adjacent to the bed, wherein the bed is covered by a bed covering such as a sheet, wherein the device is supported by the support shelf such that the base portion is not in contact with the floor. In this figure are shown tine respective locations of the various elements of the invention in this embodiment in an actual use position installed on a bed, in which the first portion 25 of the support shelf 23 is shown sandwiched between a mattress 37 and a box spring 39 and wherein the second portion 27 of the support shelf 23 is shown attached to the front face of the air channel conduit means 9 thus supporting the device 10 as a whole off of the floor upon which the leg 41 of the bed is resting. As shown in this figure, air enters the base portion 3 as indicated by the arrows at the inlet opening 5 of the base portion 3 and is caused by the action of the fan means to exit the base portion 3 at the exit opening 7 of the base portion 3 and to enter the inlet end portion 11 of the air conduit channel means 9, through which it is forced upward through the air conduit channel means 9 and out of its outlet end portion 13, whereupon it impinges upon the support bar means 17 and is re-directed in a direction as indicated by the arrows to be substantially parallel to the top surface of the mattress 37, thus providing ventilation for a person resting on the bed.
FIG. 19 shows a bed equipped with a device according to the invention, wherein the inventive device is resting on the floor. In this figure are shown the
respective locations of the various elements of the invention in this embodiment. As shown in this figure, air enters the base portion 3 as indicated by the arrows at the inlet opening 5 of the base portion 3, and is caused by the action of the fan means to exit the base portion 3 at the exit opening 7 of the base portion 3 and to enter the inlet end portion 11 of the air conduit channel means 9, through which it is forced upward through the air conduit channel means 9 and out of its outlet end portion 13, whereupon it impinges upon the support bar means 17 and is re-directed in a direction as indicated by the arrows to be substantially parallel to the top surface of the mattress 37, thus providing ventilation for a person resting on the bed. hi this figure is also shown the bed covering, which may be a blanket, sheet, etc. which is in contact with the support bar. The purpose of the support bar in this embodiment is twofold: 1) to re-direct the direction of the air as previously explained; and 2) to support the bed covering so as to prevent its interference with the air flow out of the outlet end portion 13 of the air channel means 9. Thus, the support bar means 17 holds the bed covering up off of the opening at the outlet end portion 13 of the air channel means, which enables the full air flow to ventilate the volume between the bedcovering and the top surface of the mattress 37, which usually will contain a person residing thereon.
FIG. 20 shows a frontal perspective view of a device according to an alternate form of the invention having a support shelf according to one form of the invention attached thereto, and showing the respective locations of the various elements of this embodiment of the invention including the base portion 3, inlet opening 5 of the base portion 3, support shelf 23 (elements 25 and 27 collectively), the air conduit channel means 9, the outlet end portion 13 of the air conduit channel means 9, right support arm 19, left support arm 21 and support bar means 17. hi this embodiment the support bar means 17 is disposed so ttiat it is not parallel to the outlet end portion of
the air conduit channel means 13. Such an embodiment has the advantage that by adjusting the angle which the support bar means 17 makes with respect to the horizontal surface upon which the bed rests, it is possible to elevate a portion of the bed sheets to a level that is higher than other portions of the bed sheets, to effectuate increased variability in the ability to control ventilating air flow when using a device according to the invention.
FIG. 21 shows a frontal perspective view of a device according to an alternate form of the invention having a support shelf according to one form of the invention attached thereto, and showing the respective locations of the various elements of this embodiment of the invention including the base portion 3, inlet opening 5 of the base portion 3, support shelf 23 (elements 25 and 27 collectively), the air conduit channel means 9, the outlet end portion 13 of the air conduit channel means 9, right support arm 19, left support arm 21 and support bar means 17. In this embodiment the support bar means 17 is not substantially linear and flat as in other embodiments described herein, but rather is curved, which again enables increased variability with respect to the flow of ventilating air exiting the outlet end portion 13 of the air conduit channel means 9.
FIG. 22 shows a rear perspective view of a device according to an alternate form of the invention, showing the respective locations of the various elements of this embodiment of the invention including the base portion 3, the air conduit channel means 9, the outlet end portion 13 of the air conduit channel means 9, right support arm 19, left support arm 21 and support bar means 17. From this figure it is clear how the fan means are mounted within the base portion, in one embodiment by means of fasteners disposed at two or more of the corner portions of the frame of each fan means.
FIG. 23 shows a rear perspective view of a device according to an alternate form of the invention showing the respective locations of the various elements of this embodiment of the invention including the base portion 3, which in this embodiment is cylindrical in shape, with the fan means comprising a "squirrel cage" type of fan, such as are commonly used in ventilation systems. One fan exemplary of this style of fan is manufactured by Lasko Corporation of West Chester, Pennsylvania USA, within their product model 4904; however the present invention is not limited to the use of the fan contained therein, as all squirrel cage fans of this type maybe employed, herein. It is preferable when using a squirrel cage type of fan that the inlet opening 51 comprise a plurality of holed disposed through an end portion of the cylindrical base portion 3 in such embodiments. Also shown in FIG. 23 are legs 84 attached to the cylindrical base portion (which serve as support members for providing a stable stance for the device), the air conduit channel means 9, right support arm 19, left support arm 21 and the support bar means. In one preferred form of the invention, the air channel means has a width of about 30 centimeters and a length of about 40 centimeters and comprises a channel which is 2.5 centimeters deep and about 30 centimeters long. The volume of air delivered is adjustable in the range of between about 1 cubic foot (28 Liters) per minute to about 300 cubic feet (85OO Liters) per minute. In many climates, such airflow is believed to eliminate the need for night time air conditioning, thus saving on energy costs associated with cooling an entire room. The fan means may be any fan capable of moving ' volumes of air in the above range.
