Portable Cooling Fan and Support System
A portable fan includes a housing having a first face with a first ridge and a second face with a second ridge. A recess is defined between the first and second ridges. A support member is connected to the housing. The support member can be wrapped around the recess for storage and can provide mechanical support for the housing during therapeutic use of the fan. The support member can include a handle that can be disposed under a mattress to anchor the portable fan while the patient is in bed. A second recess can be defined in the housing to receive an electric cord for storage.
The present application is directed to portable devices for circulating air to cool a patient. More particularly, the application is directed to a cooling fan having a flexible support system that is easily stowed and transported by its user.
BACKGROUNDVentilation fans are used for moving and circulating air in or through a location depending on the positioning of the fans therein. People commonly use such fans for cooling themselves in hot weather because of the cooling effect of flowing air over the person if the person is in or near the flow path of the air moved by the fan.
Persons with various medical conditions or diseases, such as diabetes, often suffer from “hot feet” or other feeling of increased warmth of a body part. This symptom can be uncomfortable to the patient, particularly at night when the patient is attempting to sleep.
Various fan assemblies that are presently available can be used to alleviate the “hot feet” symptom, such as box fans, oscillating fans, and similar devices. A problem with these fans is they are not easily portable when a user travels, for example on a business trip when the patient does not have significant extra space to carry a larger fan. In addition, the fans on the market cannot be easily adjusted to direct air towards a desired body part while the patient is in bed. In addition, the fans on the market do not have a means to manage the electrical cord to prevent accidental tripping or to streamline the aesthetic appearance of the fan assembly.
Particularly, currently available ventilation fans are not conveniently portable and are not generally suited for travel applications. Some fans are provided with rigid support brackets and are only intended for fixed mounting applications and are therefore essentially not portable at all. Other fans, e.g., oscillating room fans, are provided with a support post, which is typically a vertical cylindrical post about three or four feet in length. These products are not practically transportable and would be inconvenient to pack into one's travel luggage to say the least.
Yet other fans are more compact and come with spring or clamping mounts and short articulating or flexible stalks on which they are secured. These portable fans could possibly fit into some travel luggage, but are still limited in their utility. First, these types of portable fans are generally only available with short (e.g., 6 to 9 inch long) support posts, which do not allow much flexibility in positioning the fans. The support structures for such portable fans have a generally limited range of positioning. Also, the support posts of such system do not extend long enough to put the fans in suitably high elevations above a mounting point. In another limiting aspect, these types of fans are generally DC powered (battery or rechargeable). DC powered personal fans have a limited operating window before they require recharging or new batteries. In either case, their user would have to carry a charging station or spare batteries to continue the use of such DC fans, which makes them unacceptable for extended (e.g., overnight or long flight) use. Where small portable fans are AC powered they typically come attached to an electrical power cord typically measuring several feet in length. Such a power cord can be bunched up for packing in a suitcase or bag, but easily unravels and becomes tangled in itself or tangled with other belongings when packed for travel, or could be damaged or damage other items when packed for travel.
Publication US 2014/0112791 A1, U.S. Pat. No. 7,320,450 and similar art describe ventilation fans that can be mounted to adjustable support legs and to articulated support posts or to bendable support legs, which can therefore direct the output of the fans towards a desired direction. These systems suffer from some or all of the above-mentioned limitations.
All of the above examples have limited positioning and portability features and are not suitable for secure placement in certain environments such as will be described below. What is needed is a fan assembly that is practical for traveling users, that can be stowed in an organized and efficient compact manner, and that is also functional for users who require overnight or extended use of the fans.
SUMMARYIn an aspect, a portable fan includes a housing defining a cavity. The housing has a front face and a rear face. The front face has a front flanged face having a ridge that extends along an outer perimeter of the front face, and the rear flanged face has a rear ridge that extends along an outer perimeter of the rear face. The front and rear ridges define a recessed housing portion therebetween. A fan is disposed in the housing.
A support member is connected to the housing. The support member is capable of flexing from a portable position in which at least a portion of the support member is wrapped around the recessed housing portion, to a therapeutic position in which the support member extends away from the housing to position the fan for circulating air towards a patient.
A wire and/or electric cord is disposed in a conduit defined in the support member. The wire is in electrical communication with the fan for providing electricity thereto.
In another aspect, a portable fan comprises a housing defining a cavity. The housing has a front flanged face and a rear flanged face and a sidewall between the front and rear faces. The front face has a front ridge that extends along an outer perimeter of the front face. The rear face has a rear ridge that extends along an outer perimeter of the rear face. The housing defines a first recess between the front ridge and a middle ridge defined in the sidewall of the housing. The housing further defines a second recess between the middle ridge and the rear ridge. A fan is disposed in the housing.
A support member is connected to the housing. The support member is capable of flexing from a first portable position in which at least a portion of the support member is wrapped around the first recess, to a therapeutic position in which the support member extends away from the housing to position the fan for circulating air towards a patient.
A cord is connected to a distal end of the support member. The cord is in electrical communication with the fan for providing electricity thereto. The cord is capable of flexing from a second portable position in which at least a portion of the cord is wrapped around the second recess, to a deployed position in which the cord extends away from the housing to connect to a power supply.
A portable fan includes a housing having at least one recess in a sidewall. The recess(es) can store a support member and/or an electric cord around the housing when the portable fan is in a storage position. In therapeutic use, the support member and/or the electric cord are unwounded. The support member provides mechanical support to the fan for positioning the fan to direct cooling air towards a patient (e.g., towards the patient's feet). An optional handle is disposed at a distal end of the support member for providing additional mechanical support, for example when the support member is inserted under a mattress to cool the patient in bed. The handle can couple the support member and the electric cord. The recess(es) can include a narrowed gap through which the support member and/or the electric cord passes to a second gap for wrapping around the housing. The narrowed gap can mechanically secure the support member and/or the electric cord when they are in the storage position.
As illustrated, the front face 105 and the rear face 110 are generally circular, however other shapes are within the scope of the invention. For example, the front and rear faces 105, 110 can be rectangles, squares, triangles, etc., Alternatively, the front and rear faces 105, 110 can be oval or similar shape. In some embodiments, the front and rear faces 105, 110 are different shapes (e.g., the front face 105 is circular and the rear face 110 is rectangular).
The housing 100 defines a cavity 145 that extends from the front face 105 to the rear face 110 of the housing 100. In some embodiments, the cavity 145 extends only partially through the housing 100 (e.g., from the front face 105 to an interior region (not shown) of the housing 100). As illustrated, the cavity 145 is cylindrical, however other shapes are within the scope of the invention, such as rectangular prisms, cubes, and the like. A fan 150 is disposed in the cavity 145. The fan 150 can be disposed proximal to the front face 105, proximal to the rear face 110, or at any location therebetween. In some embodiments, two or more fans are disposed in the cavity, for example one fan 150 can be disposed proximal to the front face 105 and a second fan 150′ (not shown) can be disposed proximal to the rear face 110.
A flexible and/or adjustable support member 160 is connected to the housing 100. In some embodiments, the support member 160 includes a plurality of segments for adjusting the position of the device 10, similar to a bendable straw. The flexible and/or adjustable support member 160 can be made from plastic, metal or a combination thereof. In various embodiments, the support member 160 either acting alone, or in conjunction with its attachment mechanism, provides flexibility in as many as 5 dimensions/axes (X, Y, Z, overall length, rotational). In some embodiments, the support member 160 is highly flexible while in others the support member 160 is less flexible and/or inflexible. For example, the support member 160 can be highly flexible and can be wrapped around the recessed portion 140 for portability and/or storage, as described below. In addition, the support member 160 can position the fan 150 (e.g., by flexing a portion of the support member 160) so that the fan 150 circulates air across a desired body area (e.g., the feet), as described below. This adjustability, in conjunction with any speed control provided by the fan 150, allows a user to control which body part(s) the fan 150 circulates air across as well as the speed or volume of air being circulated. For example, the fan 150 can be set at a low speed and disposed close to a user. In another example, the fan 150 can be set at a high speed and disposed far away from the user. In each example, a desired body part of the user can receive the same air flow/volume from the fan 150 but, in the latter example, the fan 150 may not circulate air across other body parts and/or a person sleeping adjacent to the user, thus leaving him/her undisturbed.
A wire/power cord 170 extends through a conduit 180 in the support member 160. The wire 170 is in electrical communication with the fan 150 and can be electrically connected to a power source (not shown), such as an external electrical outlet or an internal or external battery. As illustrated in
In some embodiments, the support member 260 is modular and/or segmented. For example, the support member 260 can be a gooseneck arm such as a LOC-LINE® modular hose manufactured by Lockwood Products, Inc. of Lake Oswego, Oreg. Alternatively, the support member 260 can be a bendable metal, such as a metal gooseneck manufactured by SnakeClamp Products, LLC of Riner, Va., a plastic (e.g., LOC-LINE®), or a combination thereof. For example, the support member 260 can be assembled of multiple segments of different types (e.g., metal, plastic, etc.), or there may be a hybrid gooseneck that is manufactured from both metal and plastic parts.
The support member 300 includes a proximal portion 330, a middle portion 340, and a distal portion 350. The proximal portion 330 connects to the housing 360 of the device 30 at a connection point 370. The proximal portion 330 is parallel to a first axis 375, which is perpendicular to a tangent line 385 to the connection point 370. It is noted that one skilled in the art will understand that the support member 300 and the housing 360 can be disposed at various relative orientations to each other without diverting from the scope of the disclosure.
As illustrated in
One skilled in the art will recognize that the support member 300 can be adjusted in a variety of positions depending on the therapeutic need of the patient. For example, the angular section 320 can form a 30 degree angle, a 45 degree angle, a 60 degree angle, or other angle. Similarly, the support member 300 can include multiple angular sections 320, 320′ (not shown), etc. In some embodiments, the support member 300 includes an angular section (not shown) in the proximal portion 330 to direct the fan 390 downwards (e.g., generally in the direction of the distal portion 350) towards a patient's feet or other body part.
As illustrated in
In some embodiments, the first support member 610 is comprised of modular segments having a first shape (e.g., the generally conical shape illustrated in
The distal portion 750 of the support member 720 connects to the angled portion 785D of the handle member 775 proximal to an edge 745 of the mattress 720. This allows the support member 720 to be constructed out of a more flexible material that does not need to withstand the weight and pressure of the mattress 720 (and the user laying on the mattress 720). As illustrated, the angled portion 785D extends to the edge 745 of the mattress 720. However, the angled portion 785D can terminate before or after the edge of the mattress 745 in some embodiments. The handle member 775 can have an irregular shape and/or multiple sections (e.g., angular sections) to increase the surface area and/or friction between the handle member 775 and the mattress 720 or similar object (e.g., a couch) so the handle member 775 can be more securely retained and/or anchored under the mattress 720 (or similar object). As would be recognized by those skilled in the art, the handle member 775 can have various designs/shapes (including materials of the handle member 775) to provide an increased surface area and/or frictional surface.
An electric cord 782 passes through an aperture 777 defined in the angled portion 785C of the handle member 775 to carry electricity to the fan 790. The electric cord 782 can also pass through a conduit in the support member 720 (e.g., as described above with respect to
Electric cord 982 is connected to angled portion 985D of handle member 975, as described above. In the storage configuration illustrated in
In some embodiments, the angled portion 985C includes a curved extension that wraps around the housing 960 to mechanically secure the handle member 975 to the housing 960. The curvature of the curved extension can be slightly greater than the curvature of the housing 960 so that the curved extension remains relatively secure against the housing 960 due to frictional or press-fit securement of the parts. Making the ridges described above from a semi-rigid material such as plastic or thin metal allows for press fitting of the cord and/or handle of the apparatus into properly sized grooves or between the slightly flexible faces of the spool-shaped housing 960.
Similar raised edges can be disposed in the first recess 942 to secure the electric cord 982. The handle member 975 is disposed on the outside of the raised edges 918, 922 to secure the support member 920 against the housing 960 and in the second recess 944. Alternatively, the handle member 975 can be disposed on the inside of the raised edges 918, 922.
Therefore, the present invention provides an electrical fan disposed in a cavity of a device housing. The housing may be spool-shaped and have a pair of flanged or ridged faces surrounding said cavity of the device housing. A flexible electrical power cord and a flexible but supportive support member such as a goose neck extension can be wound about the device housing between said faces of the device for stowage or travel. When in use, the power cord and the flexible support member are unwound from their stowed positions into a deployed position to permit positioning the device in a desired location, including under a bed mattress, box spring, bedding, cushion or other item. In some aspects the electrical power cord can run through the center of a hollow flexible support structure and therefore be wound simultaneously therewith. In other aspects the electrical cord and the flexible support structure are wound about the body of the housing separately and in appropriately sized recessed grooves therein. In yet another aspect, the device has a graspable handle portion at a terminus of the flexible support structure that permits carrying the device and assists in supporting it during operation. The foregoing embodiments allow a person who needs a cooling fan during travel or sleep to compactly store the device when not in use or packed into his or her luggage, and to insert the device under a mattress near the bottom of a bed to cool the person's feet or other body parts as desired.
The present invention should not be considered limited to the particular embodiments described above, but rather should be understood to cover all aspects of the invention as fairly set out in the present claims. Various modifications, equivalent processes, as well as numerous structures to which the present invention may be applicable, will be readily apparent to those skilled in the art to which the present invention is directed upon review of the present disclosure. The claims are intended to cover such modifications.
