Patent number: 8388076Abstract: A face plate alignment mounting system is provided and includes a lateral adjustment means that engages a face plate and a drawer front panel, a first nut fastener, and an adjustable fastener. The first nut fastener preferably includes a head portion that is affixed to a front surface of a drawer front panel and a shaft slidably engaged with a first bore of the drawer front panel. The first nut fastener shaft defines an opening with internal threads. The adjustable fastener has external threads engaged with the internal threads of the first nut fastener shaft opening. The adjustable fastener includes a first means for adjusting the adjustable fastener in a frontward direction and a rearward direction to suitably adjust the distance between the face plate and the drawer front panel, which is preferably accessible at the rear surface of the drawer front panel.Type: GrantFiled: September 26, 2011Date of Patent: March 5, 2013Assignee: Rev-A-Shelf Company, LLCInventor: William L.

Publication number: 20120049713Abstract: A drawer slide system having an elongated base channel, an intermediate assembly at least partially received within the elongated base channel, a longitudinally extending I-beam assembly at least partially received within the intermediate assembly, and a pantry mount lock assembly including forward and rearward mounting plates adapted to be coupled to a bottom surface of a drawer. The pantry mount lock assembly can be accessed through the bottom of the drawer to achieve engagement or disengagement between the pantry mount lock assembly and the I-beam assembly. The rearward mounting plates having lateral portions extending over the upper surfaces of the I-beam assembly upper flanges to permit a tilting adjustment of the drawer relative to the drawer slide system. A soft close assembly can be included to provide a soft close for the drawer. A vertically adjustable rear panel can inhibit goods from being lost over the back of the drawer.Type: ApplicationFiled: August 10, 2011Publication date: March 1, 2012Inventors: Bryan K.

Patent number: 8047621Abstract: A system for adjustably mounting the face plate of a drawer so that when the drawer is closed, the drawer face plate is flush with the adjacent drawer face plate and in a desired height, pitch, roll, lateral and skew position with respect to the front surface of the enclosure. The drawer face panel can be easily adjusted in an inward and outward direction, or a rearward and frontward direction, to compensate for differing degrees of tilt and skew of the drawer face panel with adjacent drawer face panels. A face plate alignment mounting system is provided and includes a lateral adjustment mechanism that engages a face plate and a drawer front panel, a first nut fastener, and an adjustable fastener. The first nut fastener preferably includes a head portion that is affixed to a drawer body and a shaft slidably engaged with a first bore of the drawer body. The first nut fastener shaft defines an opening with internal threads.Type: GrantFiled: May 8, 2008Date of Patent: November 1, 2011Assignee: Rev-A-Shelf Company, LLCInventor: William L. Walburn

Publication number: 20090320724Abstract: A shelf and swivel for supporting a shelf for rotation with respect to an underlying base, the shelf including an off-axis aperture, the swivel including a first member having a plurality of openings to receive fasteners for securing the swivel to the underlying base and a pair of downward projections straddling one of the openings. A second swivel member, coupled to the first swivel member for rotation about a vertical axis, is secured to a lower surface of the shelf so that the first member openings are serially accessible through the shelf aperture. A first fastener is installed through the shelf aperture and aligned first swivel member opening into the underlying base with sufficient force to embed the projections in the underlying base, thereby inhibiting movement of the first swivel member sufficiently to permit rotation of the shelf to serially expose additional first member openings to receive additional fasteners.Type: ApplicationFiled: June 27, 2008Publication date: December 31, 2009Inventor: William L. Walburn

Patent number: 7306301Abstract: A drawer slide system providing access and stability for side access drawers has a base including an outside pair of vertical webs and a centrally situated elevated portion. Vertically oriented drawer slides are coupled to each of the vertical webs and a horizontally oriented drawer slide is coupled to the centrally situated portion of the base. The vertically oriented drawer slides are coupled to outside margins of a side access drawer adjacent to a bottom of the drawer. The horizontally oriented drawer slide is coupled to a central portion of the bottom of the drawer. The base can be fixed to a bottom surface of a cabinet to position the side access drawer within a suitable drawer receiving opening in the cabinet.Type: GrantFiled: July 1, 2004Date of Patent: December 11, 2007Assignee: Rev-A-Shelf Company, LLCInventor: William L.

Patent number: 7204569Abstract: An adjustable rack designed for mounting onto a back surface of a cabinet door includes a pair of spaced-apart, generally upright side members having an inside surface and an outside surface. At least one shelf of fixed length extends between the inside surfaces of the side members. At least one channel member is fixed to each of the side members so that at least one end is exposed to a region outside of the outside surface of a side member. The channel members have a pair of grooves in the back surface. A plurality of brackets are provided, each bracket having a pair of flanges received in the pair of grooves in a channel member back surface so that one end of the bracket is exposed from an end of a channel member. Each bracket is selected to have sufficient length to extend from the exposed end of the channel member to the perimeter frame of the door to which the rack is mounted.Type: GrantFiled: November 3, 2004Date of Patent: April 17, 2007Assignee: Rev-A-Shelf Company, LLCInventor: William L.
