FIELD OF THE DISCLOSURE
The present disclosure relates to cabinet structure, cabinets, and drawers. In particular, the disclosure relates to a slidable pullout cabinet with an adjustable face plate and an adjustable mounting bracket.
BACKGROUND OF THE DISCLOSURE
Modern kitchens place a premium on sufficient usage of storage for utensils, dry goods, and can goods. In the past, the traditional kitchen includes simple shelving to accommodate these items. However, simple shelving suffers from the drawback of unusable rear areas in corners where items are difficult to see and reach.
In an effort to overcome these difficulties, the prior art has responded by various cabinet pull out devices.
For example, U.S. Pat. No. 7,832,816 to Compagnucci discloses a frame used to support racks that slide out from a cabinet and rotate around a vertical axis. The frame comprises a rectangular structure formed of two uprights connected by upper and lower cross-pieces. The cross-pieces are coupled to telescopic sliding assemblies mounted within the cabinet. The cross-pieces are pinned to the sliding assemblies to allow the rack to rotate approximately 90° on a vertical axis such that the frame becomes parallel with the face of the cabinet only at a fully deployed position. Stops mounted to the cross-pieces prevent the frame from sliding to a stored position within the cabinet before the frame is rotated 90° such that the frame is parallel with the sliding assemblies. The device does not provide a self centering mounting base or an adjustable face plate.
U.S. Pat. No. 6,199,966 to Fulterer discloses a pullout device for a tall cupboard. The device comprises upper and lower sliding assemblies including telescopically sliding rails and running rollers. A vertically extending pullout frame, which is formed of vertical front and rear bars and horizontal upper and lower bars, is secured to the sliding assemblies. The front and rear bars and the upper and lower bars can be formed as telescopic members, permitting to adapt the device to the dimensions of the tall cupboard. A plurality of baskets can be hung between the vertical. A frontal screen is secured to the front vertical bar. The frontal screen is not easily adjustable.
U.S. Reissue Pat. No. RE41,725 to Walburn discloses a drawer slide system providing desired access and stability for a side access drawer. The system comprises a drawer having a front wall, a back wall, a base, and plurality of shelves connected between the front and back walls. The base includes a pair of vertical webs. The base is slidably mounted on an assembly comprised of one horizontally oriented drawer slide and a pair of vertically oriented drawer slides mounted to vertical webs of the base. The drawer does not provide an adjustable face plate.
Despite the advantages of the prior art, a major drawback has been that the pullout devices disclosed are not easily installed or adjusted. The prior art fails to disclose or suggest a pullout cabinet device that is easily and accurately mounted and which is easily adjustable to accommodate alignment with adjacent cabinets. Therefore, there is a need for a slidable pullout apparatus which is easily and accurately installed in a preexisting cabinet space where the apparatus is adjustable to ensure a coordinated and professional look which assimilates with cabinets already installed.
SUMMARY OF THE DISCLOSURE
In a preferred embodiment, a pantry pullout apparatus is comprised of a drawer box slidably mounted within a cabinet carcass. The drawer box is comprised of a rear panel separated from a front panel by a plurality of adjustable shelves and fixed shelves. The drawer box is fixed to a base slide box. The base slide box is comprised of a slotted template slidingly engaged with a frame, where the frame is mounted to the cabinet carcass. Slide rail assemblies connect the slotted template to the frame. A pin block on the underside of a fixed shelf automatically centers the drawer box on the slotted template. A top slide assembly is mounted to the drawer box and the cabinet carcass. The top slide assembly can be adjusted horizontally and vertically with respect to the drawer box and cabinet carcass to accommodate particular dimensions of various drawer boxes and cabinet carcasses. A cosmetic cover is attached to the slotted template and hides the slide rail assemblies connecting the slotted template to the base slide box from view.
In a preferred embodiment, a decorative face plate is attached to the front panel of the drawer box with an adjustable face plate mounting system. A slotted, rectangular bracket providing horizontal and vertical adjustment capability is connected to the face plate.

Referring to FIG. 7, base slide box 106 is shown. In a preferred embodiment, base slide box 106 is formed of wood, particle board, or polyvinyl chloride (PVC). Rail assembly 702 slidably connects frame 704 to template 706. In a preferred embodiment, rail assembly 702 incorporates three sliding rails with ball-bearing carriages; however, alternate forms of drawer rail assemblies may be employed. Frame 704 includes a plurality of mounting holes 708. Template 706 includes slot 710 located on its central longitudinal axis. Slot 710 has a first end 712 and a second end 714. Redirecting surfaces 716 are positioned at first end 712 of slot 710. In a preferred embodiment, redirecting surfaces 716 are angled generally 45° from the longitudinal axis of slot 710, however angles in the range of 30-60° would suffice. Template 706 includes mounting holes 718 either side of slot 710 proximate second end 714. A front face of template 706 includes mounting holes 724. Cosmetic cover 720 is comprised of two panels connected to each other by a pair of braces 722. Braces 722 are mounted to template 706 at first end 712 and second end 714. Cosmetic cover 720 hides rail assembly 702 from view when drawer box 102 is in the deployed position. In an alternate embodiment, no cosmetic cover is attached to base slide box 106.
Referring to FIG. 8A, the steps to install drawer box 102 in cabinet 108 are shown. At step 802, frame 704 is rigidly affixed to the cabinet carcass with standard mounting hardware such as wood screws through mounting holes 708. At step 804, “L” bracket 306 is mounted to the back of the cabinet carcass with mounting hardware such as wood screws through mounting slots 522. If necessary, vertical or horizontal adjustments of the position of “L” bracket 306 can be made without completely removing the mounting hardware due to the slotted shape of mounting slots 522. At step 806, “U” bracket 302 is connected to front panel 202 and rear panel 211 with typical mounting hardware such as wood screws through mounting slots 314. Vertical adjustments of bracket 302 are possible through the length of mounting slots 314. At step 808, drawer box 102 is positioned over template 706 such that pin block 210 is adjacent redirecting surfaces 716 at first end 712 as shown in FIG. 8B. At step 810, as drawer box 102 is pushed inward towards the cabinet, redirecting surfaces 716 guide pin block 210 towards slot 710 as shown in FIG. 8C. At step 812, as drawer box 102 is further forced towards the cabinet, pin block 210 moves through the length of slot 710 to second end 714 effectively centering drawer box 102 over base slide box 106 as shown in FIG. 8D. Pin block 210 moves through slot 710 until front panel 202 abuts template 706, mounting holes 724 are adjacent mounting holes 208, and mounting holes 212 are aligned with mounting holes 718. At step 814, drawer box 102 is attached to template 706.
At step 816, “T” bracket 304 is attached to outer rail 406 such that outer rail is positioned in between and adjacent sides 510. Curves 530 hook around outer rail 406. Tabs 504 abut outer rail 406 and position outer rail 406 centrally between sides 510. The inward bias of tabs 504 allows “T” bracket 304 to accommodate different possible widths of outer rail 406. Once “T” bracket 304 is positioned on outer rail 406, flexible tabs 502 are bent downwardly such that hooks 503 engage mounting holes 408 on outer rail 406. The engagement of hooks 503 with mounting holes 408 prevents rail assembly 308 from sliding out of engagement with brackets 304 and 306.
At step 818, rail assembly 308 is attached to “L” bracket 306 such that outer rail 406 is positioned in between and adjacent sides 516. Curves 532 hook around outer rail 406. Tabs 518 abut outer rail 406 and position outer rail 406 centrally between sides 516. The inward bias of tabs 518 allows “L” bracket 306 to accommodate different possible widths of outer rail 406. The length of web 514 provides depth adjustment capability if needed. “T” bracket 304 is then mounted to the cabinet carcass at step 820.

Referring to FIGS. 19A and 19B, bracket 1642 is shown. Bracket 1642 comprises body 1902 slidably engaged with slider 1904.
Body 1902 releasably engages outer rail 1702. Body 1902 comprises web 1908 integrally formed with sides 1910. Sides 1910 extend from web 1908 and include curves 1912. Tabs 1914 extend from each of sides 1910. Tabs 1914 are angled inward towards web 1908 such that they act as a spring and provide an inward bias. Curves 1912 hook around outer rail 1702 and tabs 1914 abut outer rail 1702. Tabs 1914 allow bracket 1642 to accommodate a range of widths of outer rail 1702. Flexible tabs 1916 extend from web 1908. Each flexible tab 1916 includes hook 1918 sized to engage mounting holes 1708 on outer rail 1702. Flange 1920 extends from body 1902. Flange 1920 includes curved sides 1922 and is sized to slidably receive slider 1904. Flange 1920 includes slot 1924.
Slider 1904 is generally “L” shaped comprising tongue 1930 extending generally perpendicularly from base 1932. Tongue 1930 is generally rectangular and sized to slidingly fit within curved sides 1922. Tongue 1930 includes tapped hole 1936. Bolt 1934 is sized to pass through slot 1924 and threadably engage tapped hole 1936. Bolt 1934 and tapped hole 1936 adjustably fasten tongue 1930 to flange 1920. Base 1932 is generally rectangular and includes slot 1938. Slider 1904 is adjustably mounted to face frame 1610 with standard mounting hardware such as wood screw 1940 through slot 1938. Bracket 1642 provides positional adjustability of upper drawer slide 1608 at end 1710 in three directions. Upper drawer slide 1608 can be adjusted vertically in direction 1632 via screw 1940 along slot 1938. Upper drawer slide 1608 can be adjusted horizontally in direction 1634 via bolt 1934 along slot 1924. Upper drawer slide 1608 can be adjusted in the depth direction 1636 via hooks 1918 releasably engaging mounting holes 1708 and tabs 1914 frictionally engaging outer rail 1702.
In use, it is important that the upper slide assembly is properly positioned relative to the cabinet carcass to decrease side-to-side movement and to prevent binding during deployment of drawer box 1602 from cabinet carcass 1604. Once lower drawer slide assembly 1606 is mounted to the support blocks and the drawer box and upper drawer slide 1608 is mounted to the cabinet carcass and the drawer box, it may be necessary to adjust the position of upper drawer slide 1608 relative to the cabinet carcass.
Referring to FIG. 20A, the steps to make a horizontal adjustment in direction 1634 of end 1710 of upper drawer slide 1608 relative to cabinet carcass 1604 are shown. At step 2002, bolt 1934 is loosened. At step 2004, tongue 1930 is repositioned horizontally relative to flange 1920 while bolt 1934 is moved along slot 1924 until the desired horizontal position of upper drawer slide 1608 relative to cabinet carcass 1604 is achieved. At step 2006, bolt 1934 is tightened.
Referring to FIG. 20B, the steps to make a vertical adjustment in direction 1632 of end 1710 of upper drawer slide 1608 relative to cabinet carcass 1604 are shown. At step 2008, screw 1940 is loosened. At step 2010, base 1932 is repositioned vertically relative to the cabinet carcass while screw 1940 is moved along slot 1938 until the desired vertical position of upper drawer slide 1608 relative to cabinet carcass 1604 is achieved. At step 2012, screw 1940 is tightened.
Referring to FIG. 20C, the steps to make a depth adjustment in direction 1636 of upper drawer slide 1608 relative to cabinet carcass 1604 are shown. At step 2014, flexible tabs 1916 are biased away from outer rail 1702. At step 2016, hooks 1918 are disengaged from mounting holes 1708. At step 2018, upper drawer slide 1608 is repositioned in depth direction 1636 relative to bracket 1642 and rear bracket 1640 until the desired depth is reached. At step 2020, hooks 1918 engage mounting holes 1708.
