FIELD OF THE INVENTION
The present invention relates generally to the field of cabinet and furniture construction, and more particularly to cabinet frame designs and associated fastening devices, methods and systems for use in cabinet and furniture assembly.
BACKGROUND OF THE INVENTION
Traditionally, some cabinets are assembled using dowels and glue, in a time consuming and expensive process that is not suitable for do-it-yourself users. Other modern manufacturing methods rely on cam connectors that, although simple in use, do not produce a stable fastening function, and generally will loosen significantly after shipping, disassembly and reassembly. Other modern connectors may function well, but are complex and time consuming to manufacture.
A traditional American cabinet has an applied frame onto which hinges, drawer slides and accessories are attached. The frame comprises of vertical stiles and horizontal rails. The current American industry standard is to utilize 1½″ or wider stiles and rails. An advantage of the traditional American construction is ease of installation, because the frame adds rigidity to compensate for building walls that are not flat, plump, or straight. A disadvantage is a reduced functional opening, which particularly reduces the width of drawer boxes.
Frameless cabinets, sometimes referred to as European-style or full-access cabinets, are made without a frame, such that the front edge of the cabinet sides form the front of the cabinet. The side is made from a sheet good, typically plywood or particle boards, and the exposed front edge of the sheet good is edge banded with PVC or wood veneer. Hinges, drawer slides and accessories are attached to the sides. The main advantages of European-style cabinets are reduced cost and an increased access opening, which allows wider drawers and more storage space. However, due to the lack of a frame causing a lack of rigidity, European-style cabinets can be difficult to install properly on building walls that are not flat, plump, or straight.
As such, considering the foregoing, it may be appreciated that there continues to be a need for novel and improved devices and methods for construction of cabinets.
SUMMARY OF THE INVENTION
The foregoing needs are met, to a great extent, by the present invention, wherein in aspects of this invention, enhancements are provided to the existing model of systems and devices for construction of cabinets.
In an aspect, a full access frame can be designed with a relatively thin frame, with stiles that are in a range of ¾″-⅞″, about half the width of conventional stiles, such that inner sides of the stiles and rails include hidden/blind connection points to facilitate hidden or blind mounting of the full access frame to cabinet sides with mounted dowel connectors that attach to the hidden/blind connection points.
In related aspects, a framed full access cabinet includes a full access frame mounted on front of a cabinet box, such that drawer rails and door hinges can be mounted on inner cabinet sides of the cabinet box.
In a further related aspect, the dowel connectors and the hidden/blind connection points can be respectively slide-in dowels and slide-in inserts.
In another further related aspect, the dowel connectors and the hidden/blind connection points can be respectively snap-in dowels and snap-in inserts.
There has thus been outlined, rather broadly, certain embodiments of the invention in order that the detailed description thereof herein may be better understood, and in order that the present contribution to the art may be better appreciated. There are, of course, additional embodiments of the invention that will be described below and which will form the subject matter of the claims appended hereto.
In this respect, before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and to the arrangements of the components set forth in the following description or illustrated in the drawings. The invention is capable of embodiments in addition to those described and of being practiced and carried out in various ways.

DETAILED DESCRIPTION
Before describing the invention in detail, it should be observed that the present invention resides primarily in a novel and non-obvious combination of elements and process steps. So as not to obscure the disclosure with details that will readily be apparent to those skilled in the art, certain conventional elements and steps have been presented with lesser detail, while the drawings and specification describe in greater detail other elements and steps pertinent to understanding the invention.
The following embodiments are not intended to define limits as to the structure or method of the invention, but only to provide exemplary constructions. The embodiments are permissive rather than mandatory and illustrative rather than exhaustive.
In the following, we describe the structure of an embodiment of a framed full access cabinet 2500 with reference to FIG. 25, in such manner that like reference numerals refer to like components throughout; a convention that we shall employ for the remainder of this specification.
FIGS. 21A, 21B, and 21C shows a conventional cabinet frame 2100, as traditionally used in American cabinet making. Conventional cabinets 2100 have relatively thick frames, normally with 1½″-1¾″ width stiles 2102, which due to their width limit access to the cabinet interior and reduce the widths of drawers that are mounted to the cabinet. All fittings 2210 are mounted on either the conventional cabinet frame 2100, such as shown in FIG. 22, and/or on the back of the cabinet (for drawer rails). Hinges and slides are mounted to inside edges of the stiles 2102.
European-style frameless cabinets instead mount fittings only on inner sides of cabinets. This provides added access but, due to the lack of a frame, European-style frameless cabinets suffer from lack of rigidity, which can make installation significantly more difficult, thus increasing installation cost, and also may limit longevity of installed cabinets.
In an embodiment, as shown in FIGS. 23A, 23B, and 23C, a full access frame 2300 can be designed with a relatively thin frame, with stiles 23022304 that are in a range of ¾″-⅞″, about half the width of conventional stiles, such that inner sides of the stiles 23022304 and rails, as shown in FIG. 23A, include hidden/blind connection points 23222324 to facilitate hidden or blind mounting of the full access frame 2300 to cabinet sides 112 with mounted dowel connectors 24222424 that attach to the hidden/blind connection points 23222324, as shown in FIG. 24.
In related embodiments, as shown in FIGS. 25 and 26, a framed full access cabinet 2500, includes a full access frame 2300 mounted on front of a cabinet box 2510. As shown, drawer rails 25122514 and hinges 2612 can be mounted on inner cabinet sides 112 of the cabinet box 2510.
In a further related embodiment, the dowel connectors 24222424 and the hidden/blind connection points 23222324 can be configured as respectively slide-in dowels 120 and slide-in inserts 130, as shown for example in connection points FIGS. 1 and 2.
In another further related embodiment, the dowel connectors 24222424 and the hidden/blind connection points 23222324 can be configured as respectively snap-in dowels 1120 and snap-in inserts 1130, as shown for example in FIGS. 11 and 12.
In various related embodiments, the framed full access cabinet 2500 allows a frame 2300 with very small stiles 23022304. Hinges 2612, drawer slides 2512, other hardware and accessories all attach to the sides 112. The frame attach points 23222324 are blind and invisible to the end consumer. Traditional American framed cabinets utilize visible stables, hotmelt glue, and visible frame-to-side attaching techniques that cannot be utilized with a flush or near flush interior side. The frame 2300 allows for the cabinet side thickness to be reduced, which costs less, but does not hinder the use of frameless hinges 2514, slides 2512 and accessories.
In an embodiment, as shown in FIG. 25, a full access cabinet 2500, can include:

In a related embodiment, FIGS. 6A-6D and 7A-7E shows, in lateral sectional cuts, that the target interior gradually expands, from an outer side in layer B 510B, shown in FIGS. 6A and 7B, to an inner side in layer D 510D, shown in FIGS. 6A and 7D, such that the shape of a front end of a slide-in dowel 120 with top front cutout 310 and a bottom front cutout 320 is configured to match with the shape of the target interior, such that when the slide-in dowel is pushed sideways from the entry interior 613 into the target interior 615, the slide-in dowel 120 will be pulled inwards to reach the matching shape of the target interior, whereby the slide-in dowel 120 is securely and tightly connected in the target interior 615. The inward pull of a plurality of slide-in dowels 120 will thereby ensure that the first and second furniture members 112114 are pulled tightly and securely together, as shown in FIG. 2.
In a further related embodiment, as shown in FIG. 7E, a bottom of the target interior 615 can include a bottom elongated guide protrusion 710, which is configured to adjust a position of the slide-in dowel 120 and ensure that the slide-in dowel 120 can be moved into the target interior 615 with minimal friction. In some embodiments the target interior 615 may not have a bottom, such that the target interior 615 protrudes through the slide-in insert 130.
In a related embodiment, FIGS. 8 and 9A-9E shows, in longitudinal sectional cuts, that the target interior provides a side opening that narrows from a 7 mm intersection position 900a, shown in FIGS. 9A and 8, towards a minimum 5 mm hold In position 900c, shown in FIGS. 9C and 8, and then expands, as shown in FIGS. 9D and 9E, such that the slide-in dowel 120 is securely held in position when the slide-in dowel 120 slides past the 5 mm hold in position 900c. Other sizing can be applied, the specific dimensions provided here are merely exemplary. FIGS. 6B and 8 show the slide-in insert 130 with the slide-in dowel 120 inserted into the entry interior 613.
In a related embodiment, as shown in FIG. 6C, the slide-in insert 130 can have serrated edges 620, which can also be referred to as ribbed edges 620, on sides of the slide-in insert 130, such that the serrated edges 620 help secure the slide-in insert 130 inside the insert aperture 115.
In a further related embodiment, the target interior 615 can be configured with a size that matches the slide-in dowels 120, such that the slide-in insert 130 expands slightly when the slide-in dowels 120 are pushed into the target interior 615, whereby the slide-in insert 130 is further secured inside the insert aperture 115, as the serrated edges expand into inner sides of the insert apertures 115. The slide-in insert 130 expands throughout the entire length 650 of a target portion 630 of the slide-in insert 130, around an entire length 650 of the target interior 615.
In a yet further related embodiment, the slide-in insert 130 can further include expansion slits 632 on an outer surface of the slide-in insert 130. The expansion slits can be positioned solely on an outer surface of the target portion 630 of the slide-in insert 130. The expansion slits 632 can be located to control the expanding portions of the slide-in insert 130, such that omission of expansion slits 632 can ensure a substrate 114 is only compressed in areas of sufficient strength.
