BACKGROUND OF THE INVENTION
The present invention relates to brewing cartridge racks and in particular to a brewing cartridge rack for attaching under a cabinet having a downward reaching lip.
A large variety of brewing cartridges are available offering a wide selection of brewed drinks. Users often desire to locate a brewing cartridge holder close to a coffee maker for easy access to the cartridges. Because counter tops can easily become cluttered with various kitchen items, and the brewing cartridges themselves are not large, a brewing cartridge rack can be positioned under the base of a cabinet.
Known under cabinet brewing cartridge holders include a cartridge holder which slides forward. Unfortunately, many cabinets include a downward reaching lip which prevents the cartridge holder from sliding forward to access the cartridges as shown in FIG. 1. One solution has been to pivot the holder at the rear as shown in FIG. 2, however, the cabinet lip still limits access to the cartridges.
BRIEF SUMMARY OF THE INVENTION
The present invention addresses the above and other needs by providing an under cabinet brewing cartridge holder including a cartridge rack which both pivots at the rear and slide forward to clear a downward reaching lip along a front edge of the cabinet. The cartridge rack includes opposing lateral pins near the rack rear, which pins slide in horizontal slots in holder side walls. A sloped rear surface limits the downward pivot of the rack, and magnets retain the rack in the stored position. In another embodiment, a second under cabinet brewing cartridge holder includes unequal length arms attach a second rack to a slider engaging the horizontal slots. The second rack pivots down and away from the holder and slides forward and rearward.

FIG. 10D shows a top view of a rear portion of a three piece cartridge rack and a cross-sectional view of a rear portion of a three piece cartridge rack taken along line 4E-4E of FIG. 4D is shown in FIG. 10E. The three piece cartridge rack includes attachable and replaceable left and right stops 48. The pins 16 may be part of the left and right stops 48 or part of the front portion 14f. 
A side view of a cartridge holder comprising a carriage drawer 14′ having rollers 60 is shown in FIG. 11A, a top view of the carriage drawer 14′ having rollers 60 is shown in FIG. 11B, and a cross-sectional view of the carriage drawer 14′ having rollers 60, in a base 12′, taken along line 12-12 of FIG. 11B, is shown in FIG. 12. The carriage drawer 14′ includes the pins 16 for sliding in the slots 18, but the rollers 60 replace the stop 24 providing a smooth manipulation of the carriage drawer 14′. The carriage drawer 14′ preferably includes channels 50 separated by walls 52 for orderly storing brewing cartridges, and the channels are more preferably sized to accept brewing cartridges sold under the name K-CUP. The base 12′ includes tracks 54 on a ceiling 56 to guide the rollers 60. The tracks may be formed by a recess in the ceiling 56, or by pairs of ridges extending form the ceiling 56, or may be a single ridge or recess matched to a roller recess or roller ridge on the roller 60.
A side view of the carriage drawer 14′ stored in the base 12′ is shown in FIG. 13A and a side view of the carriage drawer 14′ stored in the base 12′ with the cartridge drawer 14′ pivoted down and moved forward, is shown in FIG. 13B. The cartridge drawer 14′ is preferably held in the stored position by magnets 22a and 22b, but those skilled in the art will recognize that the cartridge drawer 14′ may be held by velcro, mechanical snaps, a tongue and groove, or other mechanical apparatus, and a brewing cartridge holder 10′ held in the stored position in any manner is intended to come within the scope of the present invention. The geometry of the roller 60 and pin 16 may be selected to vary the tilt of the cartridge drawer 14′ and any such selection is intended to come within the scope of the present invention.
A cross-sectional side view of a second pivoting and sliding, under cabinet, brewing cartridge holder 10a with a cartridge rack 14a stored, is shown in FIG. 14, a cross-sectional side view of the brewing cartridge holder 10a with the cartridge rack 14a pivoted down, is shown in FIG. 15, and a cross-sectional side view of the brewing cartridge holder 10a with the cartridge rack pivoted down and moved forward, is shown in FIG. 16. The cartridge rack 14a is attached to a slider 10 by unequal length arms 32a and 32b. The slider 30 slides forwards and rearwards in slots 18a. The forward end 18a′ of the slot 18a includes a longer ceiling ramp 20b′ allowing insertion of the slider 30 into the base 12a. Forward motion of the slider 30 is halted by forward stops 20c′. 
When the cartridge rack 14a is stored, the magnets 22a and 22b retain the cartridge rack 14a in the stored position. When the front of the cartridge rack 14a is pulled down, the unequal length arms 32a and 32b cause the cartridge rack 14a to tilt down at the forward end. The slider 30 may then slide forward in the slots 18a. 
Left and right vertical walls are mirror images of each other, and the cartridge rack 14a is laterally symmetric. The arms 32a and 32b are offset to avoid interference and are on both sides of the cartridge rack 14a. The holders 10, 10′, and 10a are preferably sized to hold brewing cartridges sold under the name K-CUP described in U.S. Pat. No. 5,325,765. The '765 patent is herein incorporated by reference in its entirety.
