Accordingly, it should be apparent to those skilled in the art that the following description of exemplary embodiments of the present invention are provided for illustration purpose only and not for the purpose of limiting the invention.

[0028] It is to be understood that the singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise.

[0029] It should be emphasized that the term “comprises/comprising” when used in this specification is taken to specify the presence of stated features, integers, steps or components but does not preclude the presence or addition of one or more other features, integers, steps, components or groups thereof.

[0030] In accordance with the present invention, a cabinet (A) with multiple shelves has a cabinet door (B) to access the shelves. An interior (C) of the cabinet, which is normally inaccessible in the prior art, is conveniently accessible in the present invention at the front of the cabinet (A) by means of the cabinet door (B).

[0031] The cabinet (A) comprises a first assembly (1), a second assembly (2), a plurality of coupling elements (3, 5), a first vertical axis (6), a second vertical axis (4), a plurality of pivot points (9.1, 9.2, 9.3, 9.4), a plurality of telescopic slides (10) and/or guide roller assembly (18) comprising at least one roller coupled to a rolling guide, a plurality of first type of frames (14, 17), a plurality of second type of frames (15, 11), and a plurality of horizontal arms (8, 12,13).

[0032] In the cabinet (A), the cabinet door (B) fits over the visible area of the cabinet (A). The visible area of the cabinet (A) is approximately half the exterior-accessible rectangular front area, that extends up to the adjacent perpendicular edge. As the first assembly unit (1) and the second assembly unit (2) are meant to be designed in corners of the cabinet (A), one of the assembly (1) is accessible from the front by means of a door, while the other assembly (2) is inaccessible from its immediate exterior.

[0033] As per an alternate embodiment of the present invention, all the shelves in the cabinet (A) are not designed to be placed in the corner, since there might be more than two shelves in the cabinet (A), resulting in one of the shelves to be designed in the middle of the corner shelves.

[0034] As per the present invention, the first assembly (1) is mounted on the plane of the cabinet (A), while the second assembly (2) is mounted on the front edge of the plane of the cabinet (A). The first assembly (1) and the second assembly (2) are movably interconnected by means of the first coupling element (3).

[0035] Further, as shown in FIG. 1, the first assembly (1) and the second assembly (2) are interconnected in such a way that: [0036] the first assembly (1) has a sliding and pivoting guide so as to slide and swing about the first vertical axis (6). The shelves on the first assembly (1) then move outward towards the exterior of plane of the cabinet door (B), enabling the user to access them; and [0037] the second assembly (2) has a sliding and pivoting guide so as to slide and swing on the second vertical axis (4). The shelves on the second assembly (2) then slide outward, bringing said shelves from interior (C) of the cabinet (A) towards the exterior of plane of the cabinet door (B), enabling the user to access them without reaching inside the cabinet (A).

[0038] The first vertical axis (6), on which the first assembly unit (1) slides and swings, is fixedly secured at the left or right edge of the cabinet (A). The second vertical axis (4), on which the second assembly unit (2) slides and swings, is fixedly secured 50-120 mm inside the cabinet (A), on the laterally located portion of the cabinet door (B).

[0039] In an alternate embodiment of the present invention, the distance of the second vertical axis (4) from the laterally located portion of the cabinet door

[0040] (B), varies with the size and requirement of the cabinet (A).

[0041] The first assembly (1) is mounted on either left or right side of the cabinet (A), depending on the orientation of the cabinet opening. This is illustrated in FIG. 5 and FIG. 6.

[0042] The second coupling element (5) is connected to the bottom of the rear of second assembly (2) on one side. In a first embodiment, the second coupling element (5) is directly attached to the bottom of the movable frame 11 of assembly 2 (FIG. 3). In an alternate embodiment, the second coupling element (5) is connected to a bracket (19) fixed to the bottom of frame 11 by means of a pivot point (9.1) as shown in FIG. 8. As shown in FIG. 3, the second coupling element (5) is also connected to one of the pivot points (9.2) proximate to the plane of the door of cabinet (B), at a suitable proximal distance from the second vertical axis (4) on the inner side of the cabinet (A), which results in pivotal movements.

[0043] In an alternate embodiment, the second coupling element (5) on one side is pivotally connected to a bracket (19) fixed at the rear end of the movable frame 11 of the second assembly (2) by means of a pivot point (9.1) and to the pivot point (9.2) on the other side proximate to the plane of the door of cabinet (B) as shown in FIG. 8.

[0044] The first coupling element (3) is coupled on either side with the plurality of horizontal arms (12, 13), as is illustrated in FIG. 1, FIG. 2, FIG. 8 and FIG. 9. Horizontal arm 13 is fixedly attached to bottom of frame (17) at one end and to the pivot point (9.3) on the other hand. Similarly the horizontal arm (12) is fixedly connected to bottom of frame (14) at one end and to the pivot point (9.4) on the other hand as shown in FIG. 3. One of the plurality of the horizontal arms (8) is also coupled with the second coupling element (5) either directly or by means of a bracket.

[0045] FIG. 4 illustrates the fixed coupling of the plurality of horizontal arms (12, 13) with the first type frames (14, 17). This connection between the plurality of horizontal arms (12, 13), the first and second coupling elements (3, 5), and the first type of frames (14, 17) result in the angular movement of the two assemblies (1, 2), which is again well illustrated in FIG. 4.

[0046] It is essential to understand that in the present invention, at the initiation stage of mechanism, one of the plurality horizontal arms (12) is configured to be parallel to the plane of the cabinet door (B). The other horizontal arm (13) is configured to be approximately perpendicular to the plane of the cabinet door (B), specifically in an angular range of 80°-100°.

[0047] Once the first assembly unit (1) fixed to the cabinet door (B) is pulled out by means of the cabinet door (B), the first coupling element (3) actuates the second assembly unit (2) to angularly displace outwards on the second vertical axis (4). As the second assembly unit (2) starts to move on the second vertical axis (4), the second coupling element (5) pushes the frame (11) carrying the shelves outwards. The shelves are mounted on the frame (11), movably connected with the frame (17) on the second assembly unit (2) with a pair of telescopic slides (10) (refer to FIG. 1) or a combination of telescopic slide at the bottom and a guide roller assembly on top of the movable frame 11, wherein the guide roller assembly comprises at least one roller configured to move within a guide rail (refer to FIG. 7).

[0048] The frame (11) is movably connected to the frame (17) by means of at least one telescopic slide (10). In one embodiment, there are two telescopic side mounting slides (10) to connect frame (11) and frame (17) as shown in FIG. 1. In an alternate embodiment, the frames (11) and (17) are connected by one telescopic undermount slide and one rolling assembly on the opposite side of the frames as shown in FIG. 7. The rolling assembly comprises at least one roller (18) fixedly attached to the frame (17) and configured to move inside the rolling guide mounted on the frame (11) while pivoting around the second vertical axis (4). FIG. 7, for instance, illustrates a pair of rollers fixed on frame (17). The guide roller (18) assembly is installed for smooth movement of the second assembly (2) around the second vertical pivot axis (4) as illustrated by FIG. 8 according to the alternate embodiment of the present invention

[0049] Similarly, the frame (14) is movably connected to the frame (15) by means of at least one telescopic slide (10). The telescopic slides (10) used to connect the frames may be selected from the side mounting slides, for instance, side mounted ball bearing slides as shown in FIG. 1. In an alternate embodiment, the telescopic slide is a undermount slide as shown in FIG. 8. The guide roller (18) assembly is installed for smooth movement of the first assembly (1) around the first vertical pivot axis (6) as illustrated by FIG. 8 according to the alternate embodiment of the present invention.

[0050] It is understood by a person skilled in the art that the mechanism used in the cabinet with multiple shelves of present invention is applicable for cabinets and shelves with rectangular configurations.

[0051] The mechanism as per the present invention therefore, enables the user to access the inaccessible interior (C) on the outside of the plane of cabinet door (B), without requiring the user to reach inside the cabinet.

[0052] The opening or closing (pulling or pushing) of the cabinet door (B) opens and closes all the shelves in the cabinet (mounted on the door side, at the middle of the cabinet, and at the interior-most corner of the cabinet) in a one-step action, making all the shelves easily accessible to the user. The mechanism of the present invention thus, provides a one-step solution for sliding out the inaccessible interior (C) to the exterior of the cabinet.

[0053] As per another alternate embodiment of the present invention, when the second coupling element (5) is disengaged from the second assembly (2), the shelves therein only angularly pivot on the vertical axis (4) and stop at the edge of the plane of cabinet door (B). Pursuant to this in a following step, the shelves on second assembly (2) can be manually pulled out by the user towards the outside of the plane of cabinet door (B).

[0054] Although the embodiments herein are described with various specific embodiments, it will be obvious for a person skilled in the art to practice the invention with modifications. However, all such modifications are deemed to be within the scope of the invention and claims.
