FIELD OF THE INVENTION:
[001] The present invention relates to a portable air cooling device. More particularly, the instant invention relates to an air cooling device having foldable legs in order to enable portability and adjustment of the height of said cooling device.
BACKGROUND OF THE INVENTION:
[002] The conventional air coolers available in the market perform the cooling by means of a pump, a fan and a cooling media including a honeycomb pad or wood-wool. Said coolers also require continuous use water and electricity for the purpose of performing cooling function. Said air coolers are not required during winters and must be stored thereby utilizing a lot of space.
[003] There are certain models of air coolers that may be used with or without trolleys. The heights of said air coolers are suitable for a certain level, but in case the user desires the air delivery much higher, the separate trolleys or tables are employed to lift the cooler to such height. For instance, in case wherein the window coolers are not mounted on a window, said coolers may be installed inside the homes by way of a trolley or a table.
[004] Such a cooling device has been described in US20100164256A1. Said invention relates to a foldable chair, which includes a forced air cooling system. The foldable chair includes a frame member. A flexible seat, which includes a meshed back rest suspends from the frame member. A fan bag, which has a pocket, is attached to the meshed back rest of the flexible seat. A fan is located at the bottom of the fan bag and is electrically disconnectable to a re-chargeable power source that is housed in a housing, which has an ON/OFF toggle switch so as to supply power to the fan.
[005] Such a cooling device is disclosed in CN203548076. Said invention relates to a booster engine air cooler installing support. The booster engine air cooler installing

support is characterized by comprising an upper rectangular support (1). Four supporting legs (3) are respectively hinged to the bottom of the upper support (1). Two of the supporting legs (3) are connected through a first connecting rod (2), the positions where the two ends of the first connecting rod (2) are connected with the two supporting legs (3) are provided with long grooves (5) respectively, and therefore the opening angle of the two supporting legs (3) can be adjusted. The other two supporting legs (3) are connected through a second connecting rod (4), the positions where the two ends of the second connecting rod (4) are connected with the two supporting legs (3) are provided with long grooves (5) respectively, and therefore the opening angle of the two supporting legs (3) can be adjusted. The booster engine air cooler installing support is adjustable in span and suitable for installing various wind power booster engine air coolers; in addition, assembly time can be saved and the stability of the air coolers can be improved during booster engine air cooler installation.
[006] Such a cooling device is disclosed in US4239459. Said invention relates to Method and apparatus for improving building heating and cooling, wherein relatively cooler air is circulated upwardly from adjacent the floor of a room or other space. The upwardly projected relatively cooler air displaces relatively warmer air from the upper part of the room or space, and the warmer air is displaced to a lower level, thereby tending to equalize the air temperatures at different levels of the room or space. The apparatus used for air circulation is adapted for use also in periods when cooling is required, as in summer, in a disposition to propel air horizontally. The apparatus structure includes adjustable legs permitting use of the fan or blower in dual positions.
[007] Such a cooling device is disclosed in US6644300. Said invention relates to A portable blower heater/cooler apparatus for providing 360 degrees of air-forced heat. The portable blower heater/cooler apparatus includes a base housing assembly including a base housing member being mounted upon leg members and having an opening through a top thereof and also having a screen forming a side of the base housing member; and also includes a heater/cooler assembly including a support plate being fastenable over the

opening of the base housing member, and also including a plurality of heating/cooling elements being mounted upon the support plate; and further including a cover being fastenably mounted upon the base housing member and over the heater/cooler assembly; and also includes a fan assembly including a motor being fastenably disposed in the base housing member and having a shaft rotatably attached to the motor, and also including impellers being mounted to the shaft for creating flow of air.
[008] The air coolers, as described in the prior art, do not provide the feature of height adjustment, require a lot of space and need the use tables or trolleys for the convenience of the user.
OBJECTS OF THE INVENTION:
[009] The objective of the present invention is to design an air cooling device that provides the feature of height adjustment so as to increase the height of said air cooler as per the convenience of the user.
[010] The instant invention achieves the objective by designing an air cooling device having foldable legs thereby enabling the portability and adjustment of height of said air cooling device.
SUMMARY OF THE INVENTION:
[011] The present invention relates to a portable air cooling device. More particularly, the instant invention relates to an air cooling device having foldable legs in order to enable portability and adjustment of the height of said cooling device.
[012] According to an embodiment of the present invention, there is provided an air cooling device with In-built legs which are foldable to increase or decrease its height as per user convenience and requirements. It eliminates the need to purchase separate trolley

or table to place the air cooling device which is not only difficult to carry but also creates space constraints. The air cooling device of the present invention is very much easy and convenient to store during off season period by folding the legs.
