The invention relates to portable cooling systems, and in particular, a portable cooling system that can be attached to a person's clothing.
Portable cooling systems are known. For example, various hand-held fan systems are available. However, these systems typically require that a person hold on to the fan at all times, making them inconvenient for extended use.
For example, one area of the body that may potentially require cooling for extended periods of time is the groin area. Testicles are the primary male reproductive gland in humans, and its functions include the production of sperm. The production of sperm is enhanced at temperatures that are slightly less than normal human body temperatures. Because the testicles are located outside of the body (within the scrotum), this facilitates a lower temperature for the testicles compared to normal body temperature.
However, certain environmental and non-environmental factors may affect the temperature of the testicles. These include factors such as the weather, the health of the person, the person's clothing, and the person's activity level. If these factors cause the temperature of the testicles to increase, sperm production may be impaired.
In addition to the groin area, other areas of the body may also benefit from extended cooling (e.g. the torso). There is therefore a need for a convenient and effective portable cooling system that can be attached to a person's clothing so that it does not need to held for extended periods of time.
A portable cooling apparatus comprises a holder and a fan unit. The holder comprises a clip and a backing with vent openings. A plurality of walls extends from the backing. The fan unit comprises an internal fan housed within a housing. The housing has opposed first and second housing surfaces, with intake openings on the first housing surface. Air outflow openings may be present on one end of the housing. The fan may be battery-operated and is able to circulate air from the intake openings through the outflow openings to produce a cooling effect. The fan unit may be inserted into the holder in different orientations, depending on the desired direction of air flow.
In one embodiment of the invention, a portable cooling apparatus comprises a fan unit and a holder. The fan unit comprises a housing, a fan, a plurality of intake openings, and a plurality of outflow openings. The housing comprising a first housing surface. The fan is located within the housing and is adapted to circulate air.

The foregoing was intended as a summary only and of only some of the aspects of the invention. It was not intended to define the limits or requirements of the invention. Other aspects of the invention will be appreciated by reference to the detailed description of the embodiments.
The preferred embodiment of the invention will be described by reference to the drawings thereof, in which:
Referring to Figs.1 to 9, a portable cooling apparatus 10 in accordance with the invention comprises a holder 12 and a fan unit 14, with the fan unit 14 adapted to removably attach to the holder 12. Referring to
The holder 12 is adapted to engage with a conventional belt by fitting the belt between the clip 20 and the backing 16. Preferably, the first clip portion 24 is adapted to engage with the upper edge of the belt, with the backing 16 and the second clip portion 26 on opposing sides of the belt, thereby securing the holder 12 in place with respect to the belt. Alternatively, the clip 20 and the backing 16 may be adapted to engage with the waistband for clothing, such as the waistband for pants or underwear.
Referring to
The walls 28 may also comprise one or more wall openings 38, which provide access to the fan unit 14 when the fan unit 14 is located within the holder 12.
In accordance with one embodiment, the holder 12 is approximately 3 inches wide and approximately 3.5 inches tall and approximately 1.5 inches deep. It is understood that other dimensions are also possible.
Referring to
The housing 40 comprises opposed first and second housing surfaces 44, 46 and first and second housing ends 52, 53. The first housing surface 44 comprises a plurality of intake openings 48 to allow for air flow into the fan 42. The housing 40 also comprises a plurality of outflow openings 50 for allowing the flow of air away from the fan 42. In the embodiment shown in
The fan unit 14 may comprise a power switch 54 for controlling the operation of the fan 42. The power switch 54 may be a pushbutton switch, a toggle switch, or the like. The power switch 54 may be located on the first or second housing surfaces 44, 46 or on some other surface of the housing 40.
In accordance with one embodiment, the fan unit 14 is approximately 2.75 inches wide and approximately 4.6 inches tall and approximately 1.1 inches deep. It is understood that other dimensions are also possible, so long as the fan unit 14 is able to fit within the holder 12. The fan unit 14 may also comprise a lanyard 56 extending from the housing 40. The lanyard 56 may be placed around the neck of a user 58 to allow the fan unit 14 to be suspended from the neck.
Referring to
Preferably, when the fan unit 14 is inserted into the holder 12 in this orientation, the backing 16 is spaced apart from the first housing surface 44 (forming a separation 68) so as to not completely impede the flow of air into the fan unit 14 through the intake openings 48. For example, when the holder 12 is attached to the user 58 (such as through a belt), the backing 16 may be in contact with the clothing of the user 58. This clothing may block the vent openings 18, thereby preventing any air flow through the vent openings 18. If the first housing surface 44 was in direct contact with the backing 16, then the blockage of the vent openings 18 by clothing would completely impede air flow through the intake openings 48. However, by maintaining the separation 68 between the backing 16 and the first housing surface 44, even if the vent openings 18 were blocked (e.g. by clothing), there would still be some air flow possible through the intake openings 48 through the separation 68 (i.e. from above, proximate to the backing upper edge 22). In one embodiment of the invention, the separation 68 or gap between the backing 16 and the first housing surface 44 may be between 0.125 and 0.25 inches.
The separation 68 between the backing 16 and the first housing surface 44 may be achieved in a number of ways. For example, the curvature of the walls 28 proximate to the first wall edges 34 may force the first housing surface 44 away from the backing 16. Alternatively, or in addition, a protrusion 62 may be located on a first backing surface 60 of the backing 16. The protrusion 62 serves to force the first housing surface 44 away from the first backing surface 60 thereby creating the separation 68 between the first housing surface 44 and the backing 16.
In the embodiment shown in
Referring to
Referring to
In another embodiment, the protrusion 62 may be located at other locations (besides proximate to the backing upper edge 22) on the first backing surface 60.
Referring to
In contrast,
By attaching the portable cooling apparatus 10 to the user 58, the portable cooling apparatus 10 is able to direct cooler air to the user 58. In particular, if the portable cooling apparatus 10 is attached to the waistband of the clothing of the user 58, the cooler air may be directed in either an upwards or downwards direction, providing a cooling effect for regions above or below the waist, respectively.
It will be appreciated by those skilled in the art that the preferred embodiment has been described in some detail but that certain modifications may be practiced without departing from the principles of the invention.
