[0001] The presently disclosed subject matter generally relates to air cooler, and more particularly, the present subject matter relates to a foldable cooler system.

BACKGROUND

[0002] A drawback to many conventional coolers is that such coolers generally require a large amount of storage space when not used. Such coolers are typically stored in a garage, storage shed or closet when not in use because of their size. Further, such coolers take up relatively large amounts of space whenever they are transported for use. This is particularly disadvantageous when the coolers are packed after their usage and required to carried from one place to another to provide the cooling. Because they are so large and bulky, they tend to consume a large portion of the available space, thereby limiting to leverage the usage of the air-cooler at different places. In addition to being disadvantageous for consumers, such devices also are less desirable to retailers, who have limited shelf space on which to display goods for sale.

[0003] Thus, there exists is a need of a mechanism providing the air-cooler that can be portable and be easily accommodated with optimized space and time in any conditions.

[0004] Also, it is an object of the present invention to overcome or ameliorate the above discussed disadvantages of the prior art, or at least offer a useful alternative.

[0029] Figures la and lb illustrate a perspective view of a non-foldable air cooler system, in accordance with an embodiment of the present disclosure.

[0030] It will be understood from the below description that an air cooler system 10 has a plurality of configurations that may be utilized. Various examples utilizing these configurations will now be described, although it will be appreciated that many other uses that are not described do exist and also lie within the scope of the present invention.

[0031] In an embodiment, the air cooler system 10 comprises a base 20, an upper rim 30, a cooler body frame a fastener assembly 40, and a cooler wall 50 extending between the base 20 and the upper rim 30.

[0032] The base 20 includes a bottom 24 and top surface 26. In an example, the base 20 may also include two pairs of coaxial wheels 22 each connected to the base 20 with a conventional wheel axle. The wheels 22 facilitate rolling motion of the air cooler system 10 from one location to another and are preferably constructed of a material capable of supporting the weight of the items stored in and on the air cooler system 10. It is preferred that the wheels 22 be able to support at least about ninety pounds. It is more preferred that the wheels 22 be able to support at least about one hundred and ten pounds.

[0033] The base 20 has a generally rectangular perimeter. Additionally, the base 20 is tapered such that the top surface 26 of the base 20 has a greater perimeter than the bottom 24 of the base 20. In a variation, however, the base is not tapered and, instead, includes generally orthogonal side and lateral surfaces. [0034] The upper rim 30 includes a cooling operational assembly 32. The cooling operational assembly 32 comprising a cooler motor, a water pump, a fin, pipes and an electric control unit. The cooler wall 50 is attached to the upper rim 30 and the base 20 using the fastener assembly 40. The cooler wall 50 includes a foldable inner wall 52. Preferably, the inner wall 52 are bonded, adhered, or cold-molded to the base 20. In at least one embodiment, the inner wall 52 is constructed using the industrially known standard materials that is used for constructing any air cooler system and that would impede the foldability and nesting of sections of the walls along with said base 20.

[0035] Figures 2a and 2b illustrate a front elevational view of said air cooler system 10, in accordance with an embodiment of the present disclosure. The cooling operational assembly 32 comprising a cooler motor 33, a water pump 34, a fin 35, pipes 36 and an electric control unit connected to supply switches 38.

[0036] The cooler wall 50 of the upper rim 30 is extended between and attached to the base 20 and the upper rim 30 of the said air cooler system 10. The cooler wall 50 of said upper rim comprising inner and outer collapsible and foldable walls that are folded such that the cooler is transitional between said folded configuration, the inner and outer foldable walls not requiring an intermediate space to be filled with pressurized air for support.

[0037] The cooler wall 50 comprises a common bottom wall 52 to which the foldable inner and outer walls are joined using said fastener assembly 40 and from which the foldable inner and outer walls extend.

[0038] Further, the cooler wall 50 comprises an inner foldable wall that extends from and is attached to the upper rim 30 using said fastener assembly 40, and that includes an integral bottom wall; and wherein the cooler wall comprises an outer collapsible wall that extends between and is attached to the base and the upper rim 30 of said cooler body frame.

[0039] Figures 3a and 3b illustrate a rear elevational view of said air cooler system 10, in accordance with an embodiment of the present disclosure. The fastener assembly 40 at various elevations thereof can be clearly seen, the fastener assembly 40 being arranged to support the folding and unfolding assembly of the cooler. The cooler wall 50 when fully folded, nested within an inner periphery of the base 20.

[0040] The periphery of the cooler wall 50 proximate the upper rim 30 is greater than the periphery of the cooler wall 50 proximate the base 20. [0041] Figures 4a and 4b illustrate half folded view of said air cooler system 10, in accordance with an embodiment of the present disclosure.

[0042] The cooler body frame of said air cooler system 10 is sub-divided into seven parts. Each part has its significance to make said air cooler system 10 foldable. The first part of the body frame is the water tank 22 connected to the base 20.

[0043] Initially, the side of the water tank 22 towards the front, to which a front body (i.e., connected to said upper rim 30) of the air cooler system 10 is attached. Further, rectangular clamps 42 are configured on both sides at the edge of the back of the water tank 22, the rectangular clamps 42 are thereby used to connect the back road 44 of the fastener assembly 40. [0044] In an embodiment, the front body of the air cooler system 10 is made to “L” shape; the body at both sides is provided with connecting edges. The cooler motor 33 and the fin 35 of the cooling operational assembly 32 is attached to the front body, and the control system is also connected to the front body.

[0045] In an embodiment, the upper rim 30 is designed to be folded along the front body and the back is made to be connected to the cooler back road of the fastener assembly 40 (using the rectangular clamps 42). In an embodiment, an upper body latch 46 is used at the turning point of the upper rim 30. The cooler back rods are rectangular, and these rods are connecting with the base 20 and the upper rim 30. The connection process is the type of socket system.

[0046] In an embodiment, the cooler sidewall is a water grass support body frame, and connecting with a screw support system with the sidewall cooler body. Further, this sidewall (cooler wall 50) is connected with the water tube system. Alternatively, the cooler includes a pin on the turning edge of the cooler that connects the water tank 22, front body, and upper body/rim 30. In order to prevent these edges from turning, there may be a cooler body latch (not shown).

[0047] The cooler wall 50 is attached to the upper rim 30 and the base 20 using the fastener assembly 40. In an embodiment, the fastener assembly 40 includes a cooler back body support rod assembly 42, a cooler moving edges pin 44, a cooler support body frame key 46, and a clamping panel assembly 48 mounted on both sides at an edge of a back of said cooler water tank to mechanically connect said cooler back body support rod. The clamping panel assembly comprises at least two rectangular clamps, wherein said cooler back body support rod assembly is configured to mechanically connect said cooler upper body and said base of the cooler body frame. [0048] Figures 5a and 5b illustrate a fully folded view of said air cooler system 10, in accordance with an embodiment of the present disclosure

[0049] The folded air cooler system 10 is achieved by using a simple technique and new design for able to meet/address the following: (1) difficult to enter in room if the size of the door is less than or equal to the size of the cooler (2) the frame of the cooler is customized such that it becomes a solid bag (3) this bag contains the motor and all vertical windows (4) the cooler acquires large space after use in the summer season because there is no use of cooler in the winter season (5) it is easy to carry from one place to another place easily (6) customarily more than one person is compelled to lift a cooler (7) there is no compulsion of heavy vehicle requirements for transportation we can easily carry with (bike, car, etc.,).

[0050] In an embodiment, in order to fold the upper rim 30 of the air cooler system 10, at first, the water from the water tank 22 is removed. Once, the water is completely removed then the screw connecting the cooler wall 50 is released in order to be able to release the cooler wall 50. Since, the cooling operational assembly is connected to the upper rim 30, the external connected components (such as water pipe, electrical connection wires, etc.,) should be detached before folding the upper rim 30. Hence, the water pipe is detached from the upper rim 30 of the cooler system 10.

[0051] Subsequent to detaching of all the externally connected components, the latch mechanism of the fastener assembly 40 on the side of the upper rim 30 is removed to separate the upper rim 30 from the back rod clamps of the fastener assembly 40. Further, the upper rim is turned towards under the periphery surface of the base 20, then after that, the back rod is removed, Similarly, the latch of the front side body is removed, then after that, the front side body is tilted forward, This makes easier for the sidewall/cooler wall 50 to placed inside the water tank 22 (which is empty), after that adjust the water pump further side, Thus, we hold the front body in the empty water tank 22, pack and close the back rod in the rear of the water tank 22. The back rod is engaged by closing the pins of rod. Similarly, in the reverse process, is applied to unfold the cooler body.

[0052] Figure 6 illustrates force diagram of upper folding part of a cooler body frame in accordance with an embodiment of the present disclosure. [0053] In order to take measurement about point “A”, we assume left side part of the point “A” is fixed and the right-side part is fold-able, the total weight part may be for example 1kg which lies on center of gravity point (15cm from point A).

[0054] In order to find the reaction on the point B (to support at point B) and to calculate force for holding the cooling operational assembly 32 and the upper rim 30, the following procedure is applied:

AC =15cm

Reaction at point B = Rb

Mass on COG (F)= mg=l*9.81=9.81 N

F * (AC) = Rb * (AB)

9.81 * 15 = Rb * 30

Rb = 4.905 N

[0055] Further, the above estimated force parameters are divided in to two equal parts, since there exists two support structure to which said force parameters is to be applied with same distance.

Rb’ = 2.4525 N

Rb” =2.4525 N

[0056] Figure 7 illustrates force diagram of front folding part of said cooler body frame in accordance with an embodiment of the present disclosure.

[0057] In the Figure 6, taking the moment about the point A, the center of mass of upper body is lies on point O, Weight = mg = 8*9.81 = 78.48 N, Moment MO = 78.48 * 18.4 = 1,444.032 N- cm, MO = 14.44 N-m. Thus, said momentum (calculated using procedures described in Figures 6-7) is used for folding the cooler without any external force.

[0058] Figures 8a-8c illustrate various cross-sectional view of said air cooler in accordance with another embodiment of the present disclosure.

[0059] The cooler wall 50 (including, side walls and back walls) of the foldable air cooler system 10 can be folded separately using said fastener assembly 40 and/or folded (or collapsed) directly within said water tank 22. The direct folding of said cooler wall 50 incudes the side walls folded inside towards the direction of said water tank 22, while back window first folded upper side and then inner side. [0060] By reducing the size of the cooler, the efficiency of the whole cooler decreases, so, and therefore, we cannot reduce the size of the frame of the cooler. Hence, the present disclosure provides changes in the cooler body frame without affecting the performance of the cooler. Performance of cooler means air covering the area, pump work, etc. The performance will remain the same by folding the cooler part appropriately at different-different angles and edges. Body Frame makes it worth folding on different angles and edges. The entire body frame is folded in such a way that the entire body frame joins the cooler tank. Hence, by virtue of this, only one person can transport the cooler by one hand from one place to another place. Also, reducing the need of big vehicles for transportation, since the cooler frame body is easy to fold and unfold.
