DETAILED DESCRIPTION

[0033] Referring to FIG. 1, there is provided a storage cabinet 100 which includes multiple storage units. For the purpose of ease, only one storage unit 102a is shown in the diagram and its position on the right side (dashed line diagram of storage unit 102b) however, it will be appreciated by a person ordinarily skilled in the art that there can be multiple storage units located in the storage cabinet or closet. The storage units are adapted to be mounted at and slide along a chain at each extremity of the storage units. As illustrated in FIG. 3, the storage unit 102a includes drawer rails system 302 located at each extremity of the storage unit which help the storage unit 102a to be engaged to a chain 106 through said drawer rails 302. When the storage unit 102a is located in the left side of the closet, said storage unit is engaged to a chain 106 through a drawer rail located externally in the right side X of the storage unit 102a. When said storage unit 102a moves upwardly and reaches the top part of the closed, it is engaged to the chain 106 through a drawer rail located externally in the end part T of the storage unit 102a. Similarly, when the storage unit 102b is located in the right side of the closet, said storage unit is engaged to a chain 106 through a drawer rail located externally in the left side Z of the storage unit. When said storage unit 102b moves downwardly and reaches the end part of the closed, it is engaged to the chain 106 through a drawer rail located in the top part Y of the storage unit 102b.

[0034] In another embodiment of the invention, for operative rotation the storage unit 102a includes inward depressions 202 on all four outward faces X, Y, Z and T, whereas the chain 106 includes the outward protrusions 114 (FIG. 2). The storage unit 102a is engaged in between the rail 112 and the chain 106 with the help of outward protrusions 114 and the inward depressions 202 so as to move the storage unit 102a vertically upward or downward by engaging the inward depressions 202 of the storage unit 102a with the outward protrusions of the chain 106. When said storage unit 102a moves upwardly and reaches the top part of the closed, it is engaged to the chain 106 through the inward depressions 202 located externally in the end part T of the storage unit 102a. Similarly, when the storage unit 102b is located in the right side of the closet, said storage unit is engaged to a chain 106 through the inward depressions 202 located externally in the left side Z of the storage unit. When said storage unit 102b moves downwardly and reaches the end part of the closed, it is engaged to the chain 106 through the inward depressions 202 located in the top part Y of the storage unit 102b. In another embodiment of the invention the rotating mechanism as described above may also be adapted to rotate the storage unit in a horizontal manner as well.

[0035] The chain 106 is configured to be engaged to two vertically aligned rotational gears 104a and 104b. As shown in the FIG. 1, the rotational gear 104a is connected to a set of other rotational gears 108a, 108b through a connecting chain 116. Whereas, the other extreme rotational gear 104b is connected to a set of other rotational gears 108c, 108d through another connecting chain 118. In an embodiment of the invention there is provided a rail 112 fitted between the two set of other pulleys viz. 108a, 108b and 108c, 108d. The rotational gears 108a, 108b and 108c, 108d and the rail 112 along with the rotational gears 104a, 104b form the rotational mechanism to rotate the storage unit 102. For operative rotation of the storage unit 102, the rail 112 includes outward protrusions 110 so that the storage unit is mounted to the rail 112 between two outward protrusions 110a and 110b from one side and to the chain 106 that slide along the drawer rail located outside in the extremity of the storage unit 102 so as to move the storage unit 102 vertically upward or downward. The storage unit 102 that includes the drawer rails 202 is engaged to the chain 106. In another embodiment of the invention the rotating mechanism as described above may also be adapted to rotate the storage unit in a horizontal manner as well. In this regard, the storage unit is mounted to the rail 112 from the top side between two outward protrusions 110c and 110d and to the chain 106 that slide along the drawer rail located outside around the storage unit 102 so as to move the storage unit 102 horizontally either from left to right or form right to left.

[0036] In another embodiment the invention as described above may be manually operated or with the help of linear motors so as to automatically present operator or person using the storage cabinet 100, with empty storage unit. For sensing the empty storage unit 102, there could be placed a sensor to presence the availability of things within the storage unit 102.

[0037] In an embodiment of the invention the user of the storage cabinet 100 whenever wants to access the storage unit 102 might engage the storage unit 102 manually or through an automatic means so as to move the storage unit 102 to be accessed. The user pulls down the storage unit 102 which rotates through the rotational gears 104a and 104b with the help of the chain 106. The rotation could be initiated through a linear motor (not shown in the figure) connected to an axel operatively engaged with any of the rotational gears 104a or 104b (not shown in the figure). The rotation hence initiated provides an access to the storage unit 102 being accessed by the user. Hence, in a scenario when the storage unit 102 is being moved upward, the storage unit, when reaches the top rotational gear 104a, is then moved from left side of the storage cabinet 100 to the right side as displayed by FIG. 1 (dashed line diagram of storage unit 102b). Hence on rotation, once the storage unit reaches any of the extreme rotational gears i.e. 104a or 104b, the alignment of the storage unit 102 is changed. It will be however, appreciated by a personal ordinarily skilled in the art that the rotating mechanism can also be operated in a horizontal manner as well and the rotation can be either in a clockwise manner or in a counter clockwise manner too.

Having thus described exemplary embodiments, it should be noted by those ordinarily skilled in the art that the within disclosures are exemplary only, and that various other alternatives, adaptations, and modifications may be made within the scope of the present invention.
