## Background
FIELD OF THE INVENTION
This invention relates to storage devices and more particularly to a cabinet that is mountable to one or more existing hinges and hinge pins of a door.
BACKGROUND OF THE INVENTION
Additional storage has always been a desirable commodity in homes and other structures where space is at a premium. One overlooked area in the past has been the space located behind doors. Storage devices have been developed in the past that hang over the upper edge of doors on hooks and/or attach directly to a rear surface of a door with screws, bolts and/or adhesives. However, these devices may damage the door's finish, damage the structural integrity of the door and/or make it difficult for the door to close by interfering with the door jam.
An additional problem with conventional door mounted cabinets is the size and weight of the devices, which make shipping and transportation expensive and add unnecessary weight to the door when installed thereon.
Therefore, a need exists for a hinge mounted cabinet that that is mountable to one or more existing hinges and hinge pins of a door wherein the weight of the cabinet is supported by the existing hinges, not the door, and a hinge mounted cabinet that is preferably light, modular and easy to install on any configuration of hinges.
SUMMARY OF THE INVENTION
The primary object of the present invention is to provide a cabinet that that is mountable to one or more existing hinges and hinge pins of a door wherein the weight of the cabinet is supported by the existing door hinges and not the door and a hinge mounted cabinet that is preferably light, modular and easy to install on any configuration of hinges.
The present invention fulfills the above and other objects by providing a cabinet that can be assembled from one or more sections using a plurality of internal support channels that are locked together using splines and caps to form a main body of the cabinet. An exterior support channel allows hinge hanging brackets to be easily positioned to accommodate various sized doors and hinge configurations. The use of internal support channels and external support channels eliminates the need for apertures in the main body of the cabinet. Therefore, the cabinet and sections thereof are ideally manufactured using plastic extrusion.
The above and other objects, features and advantages of the present invention should become even more readily apparent to those skilled in the art upon a reading of the following detailed description in conjunction with the drawings wherein there is shown and described illustrative embodiments of the invention.

With reference to FIGS. 1-5, the cabinet 1 of the present invention comprises a main body 2 having an interior surface 3 and an exterior surface 4, an interior side panel 5 having an interior surface 6 and an exterior surface 7, an exterior side panel 8 having an interior surface 9 and an exterior surface 10 and a rear panel 11 having an interior surface 12 and an exterior surface 13. The main body 2 houses an open storage area for placing one or more shelves 14 that extend across the cabinet 1 from the interior side panel 5 to the exterior side panel 8. The rear panel 11 may be flat or curved as illustrated herein.
Interior support channels 15 are preferably located on the interior surface 3 of the main body 2. The interior support channels 15 preferably run vertically along the interior surfaces 6, 9 and 12 of the interior side panel 5, the exterior side panel 8 and the rear panel 11. The interior support channels 15 comprise a recessed groove 16 partially covered by two flanges 17 that extend inward a predetermined distance over the recessed groove 16 to form a slot 18 that allows access to the recessed groove 16 through which various attachment means may be inserted and secured. Support posts 19 (as illustrated in FIG. 3) comprising a threaded portion 20 and nut 21 may be inserted into the interior support channel 15 and locked into desired positions to adjust heights of one or more shelves 14 within the main body 2. The support posts 19 are locked into position by rotating the threaded portion 20 of the support post 19 in relation to the nut 21 located within a recessed groove 16 of the interior support channel 15, thereby creating a pressure fit between the support post 19, nut 21 and the flanges 17 of the interior support channel 15.
The main body 2 of the cabinet 1 may be a modular unit wherein the main body 2 comprises one or more sections 22 that may be attached to each other to make a taller cabinet 1. The sections 22 are preferably secured together using one or more splines 23 that are inserted into the interior support channels 15 located on the interior surface 3 of the main body 2 and, thus, the sections 22 thereof. The splines 23 are secured using threaded bolts 24 that engage threaded apertures 25 located on the splines 23, as illustrated in FIG. 4. A joint line 26 located between the sections 22 may be covered using a piece of trim 27 that attaches to the exterior surface 4 of the main body 2.
A handle 27, which may be recessed, is preferably located on the exterior surface 10 of the exterior side panel 8 to allow a user to open and close the cabinet 1. A magnet 28 located on the cabinet 1 keeps the cabinet 1 in a closed position against the door by engaging a corresponding magnet 28 that may be installed on the door.
As illustrated in FIGS. 5 and 6, a perspective top view of a right slotted cap 29 and a perspective top view of a left slotted cap 30, respectively, are illustrated. The caps 29, 30 attach to a top 31 and bottom 32 of the main body 2. Each cap 29, 30 comprises a front edge 33, side interior edge 34, side exterior edge 35, rear edge 36, top surface 37 and bottom surface 38. Exterior support channels 39 are located on the side interior edges 34 of both the right slotted cap 29 and the left slotted cap 30 in locations that align with the exterior support channel 39 located on the interior side panel 3 of the main body 2, as illustrated in FIGS. 1 and 3. This configuration allows the cabinet 1 to be installed on any door regardless of whether the door opens to the right or the left simply by flipping the cabinet 1 upside down so the interior side panel 3 faces the side of the door where hinges are installed so the exterior support channel 39 cannot be seen from the door knob side of the door.
With reference to FIGS. 7 and 8, a perspective side view of a hinge hanging bracket 40 of the present invention and a perspective top view of a hinge hanging bracket 40 of the present invention, respectively, are illustrated. The hinge hanging bracket 40 comprises a substantially rectangular-shaped plate 43 having a top 44, bottom 45, and sides 46. At least one aperture 47 is located on the substantially rectangular-shaped plate 43. An arm 48 having a proximal end 49 and distal end 50 extends from the top of the substantially rectangular-shaped plate 43. A ring 51 and aperture 52 are located on the distal end 50 of the arm 48. An additional feature of the hinge hanging bracket 40, is that the arm 48 has a width 53 that is less than a diameter 54 of ring 51 and the distal end 50 of the arm 48. The width 53 of the arm 48 provides clearance from obstructions, such as hinge plates, molding and so forth, so the hinge hanging bracket 40 can be swung back and forth a full 180 degrees in relation to a closed door and a parallel wall. The hinge hanging bracket 40 may also be used with a wall hanging bracket instead of a door hinge. The wall hanging bracket is an L-shaped bracket that attaches to a flat surface, such as a wall or a door, using screws and/or bolts. A stud or cylindrical projection extends from one end of the L-shaped bracket to engage the ring 51 and the distal end 50 of the arm 48
With reference to FIGS. 9 and 10, a perspective side view of a partially exploded hinge hanging bracket 40 being installed on a cabinet 1 of the present invention and a perspective side view of a hinge hanging bracket 40 installed on a cabinet 1 and hinge 58, respectively, are illustrated. Exterior support channels 39 are located on the side interior edges 34 of both the right slotted cap 29 and the left slotted cap 30, as illustrated in FIGS. 4 and 5, in locations that align with the exterior support channel 39 located on the interior side panel 3 of the main body 2, as illustrated in FIGS. 1 and 3. The exterior support channels 39 comprise a recessed groove 16 partially covered by two flanges 17 that extend inward a predetermined distance over the recessed groove 16 to form a slot 18 that allows access to the recessed groove 16. One or more hinge hanging brackets 40 may be secured to the interior side panel 3 by inserting an internal mounting plate 55 comprising at least one aperture 56 into the exterior support channel 39. The internal mounting plate 55 is secured to the hinge hanging bracket 40 by one or more nuts 57 and bolts 58 that allow the internal mounting plate 55 and hinge hanging bracket 40 to be tightened together, thereby sandwiching the flanges 17 of the exterior support channel 39 between the internal mounting plate 55 and hinge hanging bracket 40.
The hinge hanging bracket 40 may be installed on a conventional door hinge 41 by removing a hinge pin 59 from a the door hinge 41 and then placing the hinge pin 59 through the aperture 52 located on the distal end 50 of the arm 48 and back into the door hinge 41. The hinge hanging bracket 40 may then be rotated on the door hinge 41 and hinge pin 59, thereby allowing the cabinet 1 to be opened and closed.
With reference to FIGS. 11 and 12, a rear perspective view of a hinge mounted cabinet 1 of the present invention having an insert 42 secured to the rear panel 11 and a sectional view along line 12-12 of FIG. 11, respectively, are illustrated. The insert 42 is preferably a rectangular-shaped piece of material, such as mirror, dry erase board, chalk board, cork board, peg board and so forth, that is attached to the rear panel 11 via an attachment means, such as adhesive, clips and so forth. As illustrated in FIG. 12, the insert 42 is attached to the cabinet 1 using retaining channels 60 located on side edges 61 of the rear panel 11. The retaining channels 60 are formed by clips 63 that extend outward from the rear panel 11 a predetermined distance and hold side edges 62 of the insert 42 against the rear panel 11, thereby sandwiching the side edges 62 of the insert 42 between the clips 63 and the rear panel 11. The retaining channels 60 and clips 63 may also be located on the caps 29, 30 to secure upper and lower edges of the insert 42.
It is to be understood that while a preferred embodiment of the invention is illustrated, it is not to be limited to the specific form or arrangement of parts herein described and shown. It will be apparent to those skilled in the art that various changes may be made without departing from the scope of the invention and the invention is not to be considered limited to what is shown and described in the specification and drawings.
